An invention may be described as made up of end view of the bed, with the form of type b b four systems or aggregations of parts, each upon it, is denoted by the dotted lines' l', Fig. system being used for the performance of a 1. The surface upon which the form rests distinct portion of the process of printing, as should be nearly a perfect plane, although it performed by the said machine-to wit, first, should be slightly concave or depressed, to the distriloutlon of the ink; second, feeding compensate for the yield of the metal, which and registering the sheets to be printed; is inevitable when impressions are being third, conveying the sheets into the press, or taken. When the press is in operation, the into that part of the machine where the im bed is caused to rise in order to produce im pressions are to be produced; fourth, produc pressions, and to sink down again to its rest ing the in pressions-each system or 'aggre ing-place in order to allow the ink-rollers to gation being so calculated and contrived pass between it and the platen to impart ink within itself, and so connected and combined to the types. The bed is kept in a horizontal witl each and all the others, that while it per positiou by means uot only of the projections forms its office in a complete and distinct man Ul, Figs. 4 and 5, arranged at its ends and ner, all receive their appropriate motions from made to slide in vertical grooves e e, Fig. 6, the same motive agent. Although some parts formed in the opposite inner sides of the frame, are in constant operation, while other parts but also by brackets c' c', Figs. 5 aud 23, one nove and stop, and lhave their periods of rest end of each of which is secured to the under and motion alternately, the said systems sev side of the bed, one at each end thereof.

These boxes are made, respectively, Fig. 1 is an elevation of the machine as to embrace the impression-bolts c, Figs. 1, 2, made with the power to move it applied by 3, and 29, upon which they slide up and means of a spur wheel and pinion, A, running down. Instead of such boxes, there may be horizontally below the flooring on which the projections at the lower ends of the brackets, machine stands.

The said 546 rocler-shaft and levers being rigid, their con true position after having been loosened for nection with the bed serves to keep the bed the temporary removal of the platen. When level in one direction. The bed is raised and the impression is to be altered, the sct-screws made to produce impressions by Ireans of gig intust be loosened or uiscrewed, and the leverse' c', Figs. 1 and 7, called “toggle-joints,” nuts g g turned as much as may be required, whicla levers may be operated by a cam; but on the completion of which the said set for the operation of which I prefer to use a screws are again to be tightened without re crank, D, and pitman or shackle-bar D', Figs. moving said pins of; but when the plater is 1 and 9. to be moved laterally from over the bed the Fig. 7 is a detached view of the toggle-joints; said pins must be taken out, while the set 1Fig. 20, the same of the impression-crank, and screws remain tight. The nuts can then be Fig. 9 the same of the said pitman. These turned back, so as to relieve the platen from toggle joints are hinged together, as seen in any pressure and allow it to be moved away Fig. 7. They are also hinged to the bed and from over the type or form. When the platen to the seat oa which they rest by means of is again brought to its place, the pin-holes in steel pins l' e” and lugs e. e., the said seat said hoops and the corresponding holes in the on which said toggles rest being on a cross platen will serve as guides by whicl the nuts bar or winter, E, Figs. 8, 25, and 34, of suffi. may be brought to the sane positions they cient strength to sustain the impression, The were in before being altered. By this con winter is placed under the machine and con trivance of the nuts g'g'', the hoops g, and the nected at its two ends,ff, with the platen by set-screws g, for increasing or diminishing means of two ve: tical bolts, cc, Figs. 1, 3, the distance between the platen IF and the and 29. winter E, I am enabled, with great ease and Fig. 25 is an elevation of the bottom bar or expedition, to insure the most accurate and winter, such as used in the press deliueated delicate, and at the same time the most per by Fig. 1; but in order to avoid inconvenieut manent, adjustment of the impression to be height in the machine, the winter may be con given to the printed sheets--a result of great structed as shown in the perspective view in value and importance in good printig.

The impression-bolts c' care provided with The bed b'l' is raised, the impression pro strong nuts g'g', which go on the ends of said duced, and the said bed lowered down again, bolts with screws, by means of which the win by little less than one-half of a revolution of ter and platen may be adjusted at a greater the crank D, and on this, account the said. or less distance from each other, in order to crank is made sufficiently eccentric to move suit the impression to the work. Upon each the pitman a little more than twice as far to of these nuts there is a hoop, g, the nut being ward the toggle joints as it is necessary to prevented from turning within the hoop by a move said joints; and a device is adopted by set-screw, f. From the lower edge of each of which the pitman is made to act on the toggle said hoops there is a projecting lip, g', having joints only during a little less than one-lalf of a hole through. it corresponding with holes in its movement toward them while tley are the platen, such holes being for the purpose raising the bed up and nroducing the impres of receiving pins g, for maintaining the nuts. sion, and in only an equal proportion in its move as well as the platen in their respective places ment in the other direction in order to lower during the operation of the machine.

The sail are also to insure the return of each nut to its levice may be described as follows, to wit: 546. 3 A portion, i', of the hitman D' is made nar. rower than the rest of it, so as to leave a its bearing against the toggle gradually nearer shoulder, i, on its under edge, which, at the and nearer to the upper end of the said lever, proper point in its motion toward the toggles, until the bearing against the toggle cones to is pressed against the elid of a lever, herein. be nearly opposite to the bearing of the shoul after called a “declension-lever, and by der of the pitman. When the shoulder of the means thereof forces the toggles tip to their pital an is pressed agaiust the upper end of the effective position. The narrower end, i, of said declension-lever, the lever will be carried for. pitman moves through an opening, i°, Fig. 7, ward by the pitman, so that the toggles by in the upper toggle, and slides on the pin it in such means will be forced gradually up to the center joint of thie toggles during that ward a vertical position, the point of resist part of its movement in which they are not in ance gradually receding from opposite the full motion. The toggle joints are the least pow (ruin aud approaching the upper end of the erful in their action for raising the bed when lever, as aforesaid, until its lower end leaves the pitman first begins to eperate upon them, its bearing or fulcrum. When this takes and the pitman.at the same time will be mov. place, the said lever will be carried along with ing at its greatest velocity toward the toggles. the toggles until the impression is produced. In its backward or retiring movement, when When the toggle joints return to their place lowering down the toggles and bed, said pit of rest, the declension-lever acts with a pro man will be moving at its greatest velocity at gressive power to bring the bed gradually to the moment when said toggles and bed arrive a state of rest. at their places of rest. Consequently a con Sometimes, when the machite is in opera trivance is necessary to prevent the injurious tion, it is desirable to prevent an impression shocks and noise which would be produced being given-as, for instance, when there is no by the sudden, starting and stopping of the sheet on the frisket; also when a sheet has bed and other parts were the shoulders of been inaccurately placed or pointed. To do the pitman allowed to impinge against the this a bar, H, Figs. 1, 2, and 27, is put across *toggle pin i without the intervention of any the macline under the pitman D', and there such device or coutrivance as above referred is a treadle, k", Figs. 1 and 2, on each side of to and hereinafter explained to modify such the machine, one treadle being attached to very oljectioiable effects. For these reasons each end of said bar, and said treadle being I employ and a range on the side of the lower hung on a pivot, as at ki, Fig.1, in a conven toggle, e, an instrument, ii, Figs. 1 and 7, ient position to enable the person feeding the which I call a “ declension-lever,” against the sheets, at either end of the machine, by press upper-end of which the shoulder i of the pit. . ing his or her foot on the treadle, to raise the man is made to operate in impelling forward pitman D' sufficiently high to allow its shoul the toggle joints.
