Referring now more particularly to the drawings, and Hitherto, in such stationary block-stationary coil ma first to the machine and method as a whole, as illustrated chines it has been a prevalent practice to provide a rotary in FiGS. 1 and 2, the same comprises an overhanging flyer drive shaft through which the wire lineally travels top head supported on a rear column 2, the overhang and emerges radially through a slot adjacent an end of 20 ing portion of the head being disposed over a well 3 in the shaft for travel over a sheave which moves in a the floor F in which is contained the support structure 4 for circular path about the block or capstan. In turn, the a pallet 5 upon which wire convolutions are accumulated block is held against rotation as by means of epicyclic in the form of an upwardly growing package or coil C. gearing between the fixed head of the machine and the The pallet 5 and its support 6 together with the three block, the flyer carrying planet gears respectively mesh 25 parallel coil support rolls 7, are mounted on the pivot 8 ing with sun gears fixed to the head and block respec for movement from tilted position as shown in FIGS. i tively. Generally, in this form of machine the end of and 2, to a position wherein the pallet 5 and support 6 the flyer drive shaft is journalled in bearings in the block. are in a horizontal plane and the coil support rollers 7 A disadvantage of this type of stationary block-stationary are vertical. Such actuation is effected as by means of coil machine is that in the case of drawing or like work 30 the fluid cylinder 9 which, when retracted, tilts the as ing of the wire the wire is wrapped around the block sembly 4 about the pivot 8 and which, when extended, under substantial tension to thus place heavy lateral thrust moves the Support 6 to horizontal position so that the and torque loads on the epicyclic gearing aforesaid and completed package C, together with the pallet 5 there on the bearings between the flyer drive shaft and the under may be pulled off the support 6. To facilitate block. 35 such withdrawal of the completed package C and its Accordingly, it is a principal object of this invention pallet 5, the support 6 may be provided with suitable con to provide a stationary block-stationary coil type of wire veyor rolls (). drawing machine and method in which the block com in order to build up a neat and compact package C prises two parts namely, a main stationary part mounted which contains a substantial weight of wire, the support directly and securely to the head of the machine so as 40 6 with the pallet 5 thereon is slowly rotated about the to be capable of withstanding such lateral thrust and tilted axis of the drive shaft is as by means of a suitable torque loads as imposed by the drawing operation as motor i2 and gearing 13, and as the convolutions of wire the flyer revolves around said main part, and a second W descend by gravity from the overhanging head 1 of take-up part which is likewise stationary and supported the machine, the convolutions will engage the upper against rotation by epicyclic type gearing, the flyer be 45 portions of the tilted rolls 7 and will thereby slide down ing operative to unwrap the convolutions from the main wardly and be displaced laterally of the axis of the sta part and wrap them around the take-up part with but tionary block assembly 15 supported by said head . very little stress on the epicyclic gearing and on the bear Thus, as the pallet 5 and support 6 slowly rotate, suc ings between the take-up part and the flyer drive shaft. cessive convolutions are laid in circular progression neat Another object of this invention is to provide a wire 50 ly and compactly. In the present case the package C drawing machine and method of the character indicated in is shown of over-center type, that is, the circularly laid which the take-up part of the two-part stationary block convolutions define a central core and form a package C aforesaid is effective to hold the convolutions around the of outside diameter less than twice the diameter of the main part and to uniformly release the convolutions for individual convolutions. An under-center package may build-up of a neat and compact package or coil. be formed by making the final package of diameter more Other objects and advantages of the present invention than twice the diameter of the individual convolutions. will become apparent as the following description pro Another form of package would be an on-center package ceeds. on which the outside diameter of the package is equal to To the accomplishment of the foregoing and related twice the diameter of the individual convolutions. ends, the invention, then, comprises the features herein 60 In any event, the rollers 7 in engaging the convolutions after fully described and particularly pointed out in the as they are progressively laid, serve to maintain the package relatively smooth on its outside diameter and, claims, the following description and the annexed drawings of course, the progressive circular laying of the convolu setting forth in detail a certain illustrative embodiment tions causes them to nest together to form a very compact of the invention, this being indicative, however, of but 65 and neat package. It is, of course, to be understood one of the various ways in which the principle of the that instead of the tilted rollers 7 as herein shown, the invention may be employed. pallet S may be provided with a tilted core member, In said annexed drawings: basket, drum, or the like which would be engaged by the FIG. 1 is a front elevation view of a wire drawing descending convolutions and laterally shifted thereby so as machine embodying the present invention, a portion of 70 to collect in circular progression on the slowly rotating the machine head being broken away to more clearly pallet 5. It has been found that neat, compact packages. illustrate the two-part block and the flyer structure; of the character indicated are formed as by maintaining a 3,064,919 3 4. speed ratio of about 800:1, that is, the support 6 and pallet by gravity therefrom, there are provided a pair of pivoted 5 make one revolution while 800 convolutions drop from arms 59 on vertical pivots 60 which have wire-engaging block assembly 15. As an example, a coil C of number shoes 61 at their ends that are pressed by tension spring 16% wire has been formed to an outside diameter of 62 against the convolutions. Thus, the convolutions are 31', an inside diameter of 11', and a height of 17' held in single-layer form in the bottom block part 47 and which weighs about 1250 pounds.
