of the type which my machine is designed to fill.

My invention relates to an improvement in automatic machines for filling the collets of lantern-pinions with the short wireswhich form their leaves, the object being to produce a simple and compact machinein which this work may be done not only far more rapidly than it can be done by hand, but also more accurately, and which may by interchanging some of its parts be adapted to fill lanternpinions of different sizes.

With these ends in view my invention consists in an automatic machine for filling lantern-pinions having certain details of construction and combinations of parts, as will be hereinafter described, and pointed out in the claims.

For clearness and convenience of description 1 proposeto describe, as far as practicable, the mechanical features of my machine in the sequence or order of their operation in filling a pinion. The machine chosen for illustration is equipped to fill relatively large pinions having eight leaves; but it will of course be understood that the size of the pinions and the number of their leaves is immaterial.

My improved machine may be made to fill pinions of one particular size,or it may have its parts made interchangeable as far as required to adapt it to beconverted for filling pinions of different sizes. It will also be understood that the wire leaves of the pinions are cut from long lengths 2 of previously-straightened wire. For use in the machine herein shown eight of these long wires 2 are gathered into a bunch, and in order that they may be conveniently handled collectively without longitudinal displacement relatively they are preferably clamped between the jaws 3 4 of a sliding clamp 5, having a rectangular opening 6, adapting it to be mounted so as to slide back and forth upon a horizontally-arranged rectangular bar 7, fixed in the frame 8 of the machine. The upper jaw 3 is controlled in the usual manner by a thumb-screw 9. The operator by taking hold of the bunch of wires or by taking hold of the clamp shoves them step by step into the machine and from time to time shifts the clamp by moving it outward on the wires and clamping it in a new position thereon, this being done as required by the shortening of the inner ends of the wires, by which is meant those portions of the wires between the clamp and the machine, due to cutting them ofi. The inner ends of the eight wires are fed into a corresponding number of holes 10, extending through ahorizontally-arranged movable cylindrical bushing 1 1, located in a circular opening 12in the machine-frame 8. These holes 10 are directly below the center of the bushing and arranged in circular form at equal distances from each other, their arrangement corresponding to the positions of the leaves in the pinionto be filled.

The eight wires 2 being distributed, so to speak, in the eight holes 10, as just described, are fed through the bushing 11 into eight alined correspondingly arranged cuttingofi holes 13, extending transversely through the lower portion of a removable disk-shaped fixed die 14 in a recess 15 formed in the outer face of the machine frame 8 and made concentric with the bushing-opening 12, but larger than the same, From the fixed die 14 the wires pass into eight correspondingly arranged and alined cutting-off holes 16,-extending transversely through adisk-shaped movable die 17, having upon its outer face a hub 18 and mounted in the forward end of a rockingleverlike carrier 19,turning upon astud 20, mounted in the machine-frame 8, the inner end of the said carrier being formed with a recess 21 for the reception of a knuckle 22, formed upon the short end 23 of a foot-lever 24, hung upon a heavy stud 25 in the machine-frame 8. Regulating-

screws

26 and 27, mounted in the machine-frame, are arranged to be engaged by the upper and lower edges of the carrier 19 to regulate the throw of the same, and hence the movement of the die 17 up and down, so that when the same is at the limit of its depressed or pinion-wire-receiving position its cuttingofi holes 16 will exactly register with the cutting-off holes 13 of the fixed die 14 and so that when it is at the limit of its elevated or pinion-leaf-delivering position its holes 16 will exactly register with the ejector-pin-guiding holes 28 of a group of eight holes extending transversely through the fixed die and located above the center thereof in lines parallel with the holes 13 thereof.

As the long wires 2 are being shoved by hand through the bushing 10, through the fixed die 14, and through the movable die 17 they are brought to a stop by means of an upright gage 29, located in line with the outting-off holes 13 of the fixed die 14 and standing close to the outer face of the hub 18 of the movable die 17 when the same is in its depressed or pinion-wire-receiving position, this gage being located at the end ofa horizontal foot 30, enteringa hole 31 in the machineframe 8 and engaged by a set-screw 32, whereby the gage is held in any desired position of adjustment. The said gage will be adjusted or set so that the space between it and the outer face of the fixed die 14 will be just sufiicient to permit the movable die 17 to be moved in between them so as to register its cutting-off holes 16 with the cutting-off holes 13 of the fixed die 14. The long wires 2 are pushed through the bushing and the cutting-0H holes of the two dies until the outer endof each wire has been impinged against the inner face of the gage, whereby uniformity in the length of the pinion-leaves 2 cut from the wires is secured.

The wires having been fed and gag-ed as described, the foot-lever 24 is operated for rocking the carrier 19 and lifting the movable die 17 into its elevated or pinion-leaf-delivering position. At the verybeginning of this movement of the said movable die the pinion-leaves 2 are produced by a shearing action of the movable die over the face of the fixed die.

These eight pinion-leaves 2 are now lifted with the movable die and brought into registration with the eight holes 28 of the upper group of ejector-pin-guiding holes in the fixed die. An unfilled pinion consisting of an arbor 33 and two

collets

34 and 35 now has one end of its arbor inserted into a bearing-hole 36, extending transversely through the movable die 17 and located in the center of its group of cutting-off holes 16. The fixed die 14 is formed with a corresponding bearinghole 37, located in the center of its group of ejector-pin-guiding holes 28 for the reception of the extreme end of the arbor in case it happens to be long. It will be understood, of course, that each of the

collets

34 and 35 have had drilled in them eight holes corresponding in size and arrangement to the several groups of holes already referred to, the holes 35 in the collet 35 being open holes in the sense of extending through the collet and the holes 34 in the collet 34 being closed holes or pockets in the sense that they do not extend through to the outer face thereof. In applying the unfilled pinion to the machine that end of its arbor 33 will always be inserted into the hole 36 of the movable die which will bring the collet having the open holes 35 into immediate proximity to the outer ends of the holes 16 in the movable die. The leaves 2 are now ejected from the holes 16 in the movable die 17 and introduced into the

said collets

34 and 35 by means of a group of eight ejector-pins 38, having a circular arrangement corresponding to the arrangement of the several groups of holes and mounted at their inner ends in an ejector-head 39. These ejectorpins 38 play back and forth in the ejector-pinguiding holes 28 of the upper group of holes in the fixed die 14 and through the holes 40 of a corresponding group of holes formed in the bushing 11 at a point centrally above the lower group of holes 10 therein. The said head 39 has its outer end slotted for the reception of a finger-lever 41, to which it is attached by a pivot 42, the said finger-lever being furnished at its outer end with a fingerpiece 43 and having its inner end hung by a pivot 44 in a post 45. At its extreme inner, end the finger-lev er .is furnished with an eye 46, receiving an adjusting-screw 47, by means of which the ejecting throw of the pins 38 is regulated. A spring 48, interposed between the finger-lever 41 and the machine-frame 8, operates to retract the ejector-pins 38 into .their retired positions after they have been used to transfer a set of pinion-leaves from the movable die to an unfilled pinion.

The operation of my improved machine is simple and extremely rapid, the long wires being fed by one hand to the gage, after which the foot is operated to cut them off and lift the movable die to the limit of its upward movement. An unfilled pinion is then applied by the other hand to the said movable die, after, which the other hand is used to operate the finger-lever for the ejection of the pinionleaves into the unfilled blank, which is then removed for the closing of the outer ends of the holes 35 in its collet 35 by swaging or otherwise.

It will be apparent that by interchanging the fixed and movable dies, the bushing, and the ejector-pins the machine may be converted for filling pinion-blanks of any size and number of leaves. It is also apparent that in carrying out my invention some changes from the construction herein shown and described may be made. I would therefore have it understood that I do not limit myself thereto, but hold myself at liberty to make such departures therefrom as fairly fall within the spirit and scope of my invention.
