2 3 THE ERWIN SATTLER PRECISION PENDULUM CLOCKS

Your decision to purchase the precision pendulum clock with seconds pendulum shows that One of the reasons why you decided to purchase this pendulum clock is its accuracy. The you belong to the very small circle of special connoisseurs of highest mechanical clockmaking accuracy does, however, not only result from the mechanical factors of the clockwork. It does art. Your new clock is after all a first-class product of our company concerning its construction, also depend upon external, physical influences. The period of oscillation of the pendulum is faithfulness to details and last but not least its great manufactural expense. thus mainly determined by its physical length. Changes of temperature, as is generally known, Such a precious instrument naturally has to be handled with a high degree of care. Let alone result in a variation of length according to the longitudinal expansion coefficient of the for this reason you should read the following information and follow the advice given. You will materials imployed. The pendulum rod of your clock consists of a material called super invar. thus be able to enjoy your pendulum clock for many decades. This iron-nickel alloy reacts on changes of temperature only to very small extent. And this is to a very large extent compensated by an exactly calculated temperature compensation. In order to protect them from corrosion, all brass parts of the clock are gold-plated. The exact Due to work tolerances during manufacture of the material a minimal compensation error may fine machining and the arrangement of the bearings concerning the gears and all parts of however occur. It is thus advisable to expose your clock to merely small changes of tempera- the escapement ensure – good maintenance being presupposed – perfect function for ture. If you observe this when choosing the place for the clock, the deviations of accuracy may generations. come to approx. 2 seconds per month. Since the period of oscillation of a pendulum extends when air pressure rises, your clock is equipped with a barometric-error compensation. It consists of aneroid boxes and a weight, which is during changes of air pressure moved upwards or downwards to an exactly defined degree, thus reacting to a change of the period of oscillation. Finally it has to be observed that vibrations transmitted to the pendulum and the suspension spring result in deviations of accuracy. While opening or closing the clock case you should therefore avoid shocks. The wall to which the clock is fixed should therefore also be as stable as possible.

4 5 CLASSICA SECUNDA 1985 AND 1995 Mounting the clock on the wall Precision pendulum clocks Choose for your clock a place on a stable wall without direct insulation, in order to prevent the clock case from heating up and to come up to the weight of the clock. To avoid damage of the clockwork and the case during mounting, the following work should only be done by an experienced clockmaker. Necessary tools: stone drill 10 mm, drilling machine, socket wrench 13 mm or a ratchet wrench with 13 mm socket. For the installation of the clock we provide two possibilities: 1) For a temporary installation in a store use the hanger plate on top of the back wall of the clock. 2) For the ﬁnal installation the clock must be bolted to the wall through the central drilling in the movement holding plate. (hanger bolt with 2 washers and cap nut is included).

Unpacking Please unpack the clock carefully (keep the packing material for possible transports of the clock). Caution! With the clock, there is a protecting cover that has to be laid inside the bottom of the case! The cover has to be used, to avoid damages of the case! Please remove the cover only after the installation is complete!

How to take out the movement Unscrew the four knurled movement holding nuts, pull the movement up to the front out of the case and put it carefully down on an even and ﬁrm underground with the dial downwards.

6 7 How to align the clock case How to ﬁt in the movement For optimal readability we suggest to place the 10 mm drilling for the wall plug approximately Remove the safety rubber band from the pallet. Push the movement on the 4 pillars and screw in eye height (ca. 180 cm). This position is equivalent to the centre of the dial. it down with the four knurled nuts. Remove the transport protection of the escapement lever. Insert the wall plug. Screw in the hanger bolt with the cap nut until the bolt protrudes 4 cm So that motion can be transmitted from the movement to the pendulum, the driving pin of the from the wall. Take off the cap nut again. pallet lever must be inserted in the triangular cut-out in the safety ﬂap on the beat adjuster. Now hang the empty case with the central drilling over the washers and the cap nut and screw To do so, reach behind the movement from the side, carefully press the lever with the cut-out the hanger bolt deeper into the wall until the case is pressed gently to the wall. Put the case backwards and upwards until the driving pin slots into the triangular cut-out. in vertical position by using a water level. Now screw in the for case screws located in the corners of the clock case until the tips get stuck in the wall.

How to set the barometer hand The scale of the barometer does not correspond to the display of changes of pressure measured in hectopascal, as is nowadays the case with barometers. The scale does rather display the changes of pressure, as it was formerly done, in millimetre mercury column. When the pressure at the destination of the clock is »normal« adjust the display by setting the hand of the barometer to zero by turning the knurled-head screw above the aneroid boxes. Push back the protection tube on the suspension spring block. Because of the lateral mounted You can now read the reactions of the barometer to changes of pressure as follows: High air pressure compensation, the pendulum is pushed slightly from the centre position to the pressure is displayed in the upper half of the scale, in the »positive« range, low pressure is side. By turning the nuts at the sides of the pendulum scale you can adjust the pendulum scale displayed in the lower half of the scale, in the »negative« range. If the pressure increases the in a position that the tip of the pendulum points exactly to »0«. period of oscillation of the pendulum lengthens, thus the clock is slow. By the compression of the aneroid boxes however, the weight located on them sinks towards the centre of the pendulum, resulting in the acceleration of the pendulum. The change in speed caused by the change of pressure is thus compensated.

8 9 How to start the clock Before hanging the weight into the pulley, make sure the cable runs in the front groove of the guide pulley. Wind the clock with the crank one turn counter clock wise. Deflect the pendulum until a »tick«, caused by the drop of the escapement wheel tooth on the pallet, is audible. Watch the pendulum scale and note the angular minutes, indicated by the tip of the pendulum, exactly in the moment where the »tick« occurs. Now deflect the pendulum to the other side and again note the angular minutes when the »tick« is audible. It is ideal, when the angular minutes are equal on both sides. Compensation tube If the pendulum has to be deflected more to the right side than to the left to hear the “tick“, you can correct this by turning the adjustment screw on the pendulum rod behind the movement to the right side. Regulation nut Stop winding the clock, when the top end of the pulley is about 1 cm below the dial ring. Lock nut Pendulum rod How to set the time Whole for regulation pin When setting the time, the minute hand may be turned forwards as well as backwards. The second hand shall not be turned. In order to synchronise the second hand to that of another clock (e.g. a radio clock) stop the pendulum when the second hand has reached the mark of the sixtieth second. Let the pendulum go when the second hand of the clock of comparison reaches the sixtieth second. b) Precision adjustment: How to adjust the accuracy For precision adjustment of the clock, i.e. for the correction of small deviations of accuracy, you don’t need to stop the pendulum. Your clock has been exactly adjusted in our workshop. The transport, the sea level and the geographic latitude of the place where the clock is hung up may however lead to a variation Precision adjustment is done by means of the timing weights in the case. Place them on in the period of oscillation of the pendulum. You will therefore most probably have to adjust the adjusting-table situated at the middle of the pendulum rod. your clock once again. The heavier the timing weight, the greater the acceleration of the pendulum, i.e. the faster Adjust your clock as follows: runs the clock. a) Coarse adjustment: By taking away a timing weight, the period of oscillation of the pendulum is lengthened, Should the accuracy deviate by more then one second per day it is necessary to adjust the i.e. the clock goes slower. clock by the adjusting nut. c) How to correct deviations of 1 - 2 seconds from standard time: Please stop the pendulum first. Now put the regulation pin enclosed in the case into the You can correct deviations of 1 - 2 seconds from standard time with the aid of the two hole below the counter nut in the pendulum rod to avoid a twisting of the suspension stainless steel regulation weights also enclosed in the case. You neither need to stop the spring during adjustment. pendulum, nor the second hand. One of the weights should thus always be located on the adjusting table. Loosen the lower nut, the lock nut, and then screw the adjusting nut one line to the left per second gained per day, i.e. one line to the right per second lost per day. Afterwards In case the second hand deviates approx. minus 1 second from standard time, place the screw the lock nut slightly up again. second weight onto the adjusting table as well. As soon as the deviation is recovered, take the weight off again. After having watched the accuracy a couple of days you may readjust the clock as described above. A deviation of approx. plus 1 second shall be corrected by occasionally taking away the weight permanently located on the adjusting table.

You can now airpressure compensation, the pendulum is pushed slightly from the centre position to the read the reactions of the barometer to changes of pressure as follows: side. By turning the nuts at the sides of the pendulum scale you can adjust the pendulum scale High pressure is displayed in the upper half of the scale, in the »positive« range, low pressure in a position that the tip of the pendulum points exactly to »0«. is displayed in the lower half of the scale, in the »negative« range. If the pressure increases the period of oscillation of the pendulum lengthens, thus the clock is slow. By the compression of the aneroid boxes however, the weight located on them sinks towards the centre of the pendulum, resulting in the acceleration of the pendulum. The change in speed caused by the change of pressure is thus compensated.

Necessary tools: stone drill 10 mm, drilling machine, socket wrench 13 mm or a ratchet wrench with 13 mm socket. For the installation of the clock we provide two possibilities: 1) For a temporary installation in a store use the hanger plate on top of the back wall of the clock. 2) For the ﬁnal installation the clock must be bolted to the wall through the central drilling in the movement holding plate.

This position is equivalent to the centre of the dial. To do so, reach behind the movement from the side, carefully press the lever with the cut-out backwards and upwards until the driving pin slots into the triangular cut-out. Insert the wall plug. Screw in the hanger bolt with the cap nut until the bolt protrudes 4 cm from the wall. Take off the cap nut again. Now hang the empty case with the central drilling over the washers and the cap nut and screw the hanger bolt deeper into the wall until the case is pressed gently to the wall. Put the case in vertical position by using a water level. Now screw in the four case screws located in the corners of the clock case until the tips get stuck in the wall.

26 27 Adjusting the striking mechanism The striking mechanism’s hammer is generally factory adjusted. If, however, the hammer should have gone out of adjustment (perhaps as a result of being transported), it can be readjusted by means of a special mechanism on the rear of the movement. This will be necessary if the hammer is too far from the gong (so that the gong is then too quiet) or too close to it (so that the gong »buzzes«). Please note: do not on any account bend the gong! At the 7:30 position on the clock face you will see behind the movement a knurled thumbwheel Compensation tube protruding vertically downwards. By turning it, you can precisely set the hammer gap.

Disabling the striking mechanism Regulation nut The Classica Sonata has a facility for disabling the striking mechanism. It consists of a small Lock nut lever located behind the 9:30 position on the clock face on the inside of the rear plate. If that Pendulum rod lever is pressed downwards as far as the stop, it disengages the hammer from the striking mechanism so that the clock no longer strikes. Whole for regulation pin If you want to re-enable the striking mechanism, press the lever upwards as far as the stop. Please note: the hammer weight continues moving even when the striking mechanism is disabled. b) Precision adjustment: How to adjust the accuracy For precision adjustment of the clock, i.e. for the correction of small deviations of accuracy, you don’t need to stop the pendulum.

To do so, reach behind the movement from the side, carefully press the lever with the cut-out backwards and upwards until the driving pin slots into the triangular cut-out. Lift the glass door from the hinges and hang the case back with the hanging plate over the screw, mentioned above. Remove the screw covers in the 4 corners of the case, level the case and mark the positions through the 4 holes. Remove the case back, drill the 4 holes and insert the plug. Before hanging the case back to the wall, open the right cover seen from behind, remove the protection material from the gong tube and close the cover again. Now you can ﬁnally mount the case back with the 4 screws to the wall. Hang in the glass door and adjust the hinge and hook elements to ensure good opening and closing of the door. Adjusting the gong With the eccentric at the case plate the clearance between hammer and gong tube can be adjusted for a good sound of the gong.

How to hang in the pendulum Caution! Do always hold or carry the pendulum at the free pendulum rod, never at the adjusting-table or the plate of the barometer-instrument. Since the movement is already removed, the nickel-plated protection tube can be pulled How to start the clock off from the suspension spring block (located between the two upper movement holding When hanging the weights in the pulleys, please make sure that the steel cable is properly pillars). seated in the groove of the pulley in each case. Remove the suspension spring Please note that: the weight with the marking/inscription on the bottom »left« must be and keep in reach. Now unscrew the suspended from the left pulley – it is the heavier weight. protection cap from the tip of Using the crank, the clock is wound up one revolution in anti-clockwise direction. While the pendulum. To avoid damage of precisely observing the tip of the pendulum and the scale, you now very slowly deflect the the delicate suspension spring we pendulum sideways until – brought about by the escape wheel falling against the pallet recommend to insert it into the slot lever – a »tick« is heard. You must then make a note of the number of angular minutes of the pendulum rod first, hold it in shown on the scale precisely at the point the tick is heard. Then you deflect the pendulum to place and then hang the pendulum the other side until you hear the »tock«. Ideally this should occur at the same number of together with the suspension spring minutes on the scale in the other direction. If, for example, the pendulum has to be deflected into the suspension spring block. further to the right for the tick to be heard than to the left, you can correct this by turning the Push back the protection tube on the suspension spring block.

If you want to re-enable the striking mechanism, press the lever upwards as far as the stop. In case the second hand deviates approx. minus 1 second from standard time, place the Please note: the hammer weight continues moving even when the striking mechanism is second weight onto the adjusting table as well. As soon as the deviation is recovered, disabled. take the weight off again. A deviation of approx. plus 1 second shall be corrected by occasionally taking away the How to adjust the accuracy weight permanently located on the adjusting table. The clock has been exactly adjusted in our workshop. Transport and variations of the geographical height can however lead to a change of the period of oscillation of the pendulum. It will thus in most cases be necessary to adjust your clock anew. Adjust your clock as follows: a) Coarse adjustment: Should the accuracy deviate by more then one second per day it is necessary to adjust the clock by the adjusting nut. Please stop the pendulum first. Now put the regulation pin enclosed in the case into the hole below the lock nut in the pendulum rod to avoid a twisting of the suspension spring during adjustment. Compensation tube Loosen the lower nut, the counter nut, and then screw the adjusting nut one line to the left per second gained per day, i.e. one line to the right per second lost per day. Afterwards screw the counter nut slightly up again. Regulation nut After having watched the accuracy a couple of days you may readjust the clock as described above. Lock nut b) Precision adjustment: Pendulum rod For precision adjustment of the clock, i.e. for the correction of small deviations of accuracy, Whole for regulation pin you don’t need to stop the pendulum. Precision adjustment is done by means of the timing weights in the case. Place them on the adjusting-table situated at the middle of the pendulum rod. The heavier the timing weight, the greater the acceleration of the pendulum, i.e. the faster runs the clock. By taking away a timing weight, the period of oscillation of the pendulum is lengthened, i.e. the clock goes slower.

52 53 METALLICA 1735 Mounting the clock on the wall Choose for your clock a place without direct insolation on a stable wall in order to pre-vent 5/6 Precision pendulum clock the clock case from heating up and to come up to the weight of the clock. In order to prevent damage to the clockwork and the clock case during assembly, the following work should only be done by experienced clockmakers. Necessary tools: stone drill 10 mm + 6mm, drilling machine, socket wrench 13 mm or a ratchet wrench with 13 mm socket, crosstip screwdriver. For the installation of the clock we provide two possibilities: 1) For a temporary installation in a store use the hanger plate on top of the back wall of the clock. 2) For the ﬁnal installation the clock must be bolted to the wall through the central drilling in the movement holding plate (hanger bolt with 2 washers and cap nut is included).

Unpacking Please unpack the clock carefully (keep the packing material for possible transports of the clock).

Caution! With the clock, there is a protecting cover that has to be laid inside the bottom of the case! The cover has to be used, to avoid damages of the case! Please remove the cover only after the installation is complete!

How to take out the movement Unscrew the two knurled movement holding screws, pull the movement up to the front out of the case and put it carefully down on an even and ﬁrm underground with the dial downwards.

How to hang in the pendulum Caution: Do always hold or carry the pendulum at the free pendulum rod, never at the adjusting-table or the plate of the barometer-instrument. How to set the clock in motion Now unscrew the protection cap from the tip of the pendulum. To avoid damage of the delicate Before hanging the weight into the pulley, make suspension spring we recommend to insert it into the slot of the pendulum rod ﬁrst, hold it in place sure the cable runs in the front groove of the guide and then hang the pendulum together with the suspension spring into the suspension spring block. pulley. Then hang the weight in the bow of the rope pulley without bending the steel cable.

Wind the clock with the crank one turn counter clockwise. Deflect the pendulum until a »tick«, caused by the drop of the escapement wheel tooth on the pallet, is audible. Watch the pendulum scale and note the angular minutes, indicated by the tip of the pendulum, exactly in the moment where the »tick« occurs. Now deflect the pendulum to the other side and again note the angular minutes when the »tick« is audible. It is ideal, when the angular minutes are equal on both sides. If the pendulum has to be deflected more to the right side than to the left to hear the »tick«, you can correct this by turning the adjustment screw on the pendulum rod behind the movement to Because of the lateral mounted air pressure compensation, the pendulum is pushed slightly from the left side. the centre position to the side. By turning the nuts at the sides of the pendulum scale you can Stop winding the clock, when the top end of the pulley is about 1 cm below the dial adjust the pendulum scale in a position that the tip of the pendulum points exactly to “0”. ring.
