I, EMMA F. SHEPARD, administratrix of the estate of said EUGENE H. SHEPARD, deceased,

hereby declare that the following description, in connection with the accompanying drawings, forming a part thereof, is a specification.

This invention relates to improvements in machines for forming bundle carriers of the well-known type in which a wire passes through a wooden handle and has its ends bent to form loops for engaging the strings or cords which fasten the bundles and said machine is adapted to bend the wire in the handle.

The machine has mechanism for performing three different functions in the process of forming the carriers. First, mechanism for feeding the blanks, second, mechanism for bending the wire and third, mechanism for ejecting the carrier when wholly formed. The entire mechanism is mounted on a frame of suitable structure and a carrier is formed at each revolution of the main shaft.

In the drawings herewith accompanying and making a part of this application, Figure 1 is a plan view of said machine, the feeding mechanism being removed, parts of the mechanism being broken away and parts omitted for the sake of clearness. Fig. 2

is a side elevation of said machine; Fig. 3 is a longitudinal sectional view of said machine with parts omitted for the sake of clearness: Fig. 4 is a detail view of a carrier when completed; Fig. 5 is a detail view of the post carrying the loop forming devices; Fig. 6 is a transverse sectional view of the hopper taken on line X--X Fig. 2, and Fig. 7 is a detail view of a portion of the main shaft and its cams.

The same reference characters indicate like parts in the several views.

The feeding mechanism.Upon a suitable frame 1 a hopper 2 is pivotally mounted being hung on a transverse bar 3 supported by uprights 4 secured to the top of said frame, said hopper extendin transversely of the frame. The hopper has. a central handle receiving sect-ion 5 and two wire receiving sections (3, the handle receiving section being larger than the wire receiving sections. The handles with straight wires inserted therein are fed into the hopper in any convenient manner of which I have shown one consisting of an inclined tray 7, its lower end coinciding with the opening in the top of the hopper so that, when the handles with the wires therein are placed in the tray they will roll by gravity into the hopper, the hopper being arranged so that the handles will lie one on top of the other therein and be discharged in the operation of the machine one at a time at predetermined times to the wire bending mechanism hereinafter described. The lower end of the hopper is free to swing and is operated by a link 8 connected one end to the side of the hopper near the bottom and the other end to a two-arm lever 9 mounted on the rock shaft 22 and operable by means of a cam 10 on the main shaft 11 mounted in downwardly extending portions of the frame 1, the rotation of the cam moving the lower extremity of the hopper forwardly. A spring 12 connected one end to the upper end of lever 9 and the other end to some part of the machine frame tends constantly to hold the hopper yieldingly in normal position and to return it to normal position when moved forward by the cam lever, the forward movement of the lower extremity of the hopper bringing the discharge end of the hopper directly over the holding mechanism into which a single handle and wire falls at each forward movement of the hopper.

The wire bending me0ham'sm.-The wire bending mechanism comprises two similar trains of mechanism, one on each side of the machine, each adapted to bend the wire at one side of the handle, both trains being operable simultaneously. On the top of the frame of the machine is a reclprocatmg plunger 13, on the forward end of which are two pairs of handle holding posts 14 and 15 spaced apart from each other longitudinally of the machine, one pair 15 being ad justable longitudinally in the machine. The movement of said plunger 13 is timed so as to bring said handle holding posts periodically below the open end of the hopper, permitting a single handle and wire to fall from the hopper between said handle holding posts and end stops 73 laterally adjustable on the frame of the machine whereupon the hopper moves back to normal position, the lower end of the hopper being closed temporarily by any convenient means, as shown, by the horizontal portions 16 of the holding posts 15. Pivotally attached to the top of the machine on either side thereof are levers 17 carrying on their forward end wire bending posts 18 preferably tapering downwardly. A lateral swinging motion is imparted to said levers by means of toggles l9, pivotally attached to the levers and to the plunger 13. The wire bending posts 18 are positioned so that the wire in the handle lies in front of the posts 18 when the plunger is withdrawn. WVhen the plunger is moved forward the toggles cause the ends of the levers 17 011 which the wire bending posts are mounted to move toward each other against the free ends of the wire in the handle, bending the wire to a position at right angles to the handle. The plunger 13 is operable by means of a link 20 secured one end to the plunger and the other to an arm 21 set on a rock shaft 22 mounted in the frame. Rigidly secured to shaft 22, are forked arms 23 working against cams 24 on the main shaft, whereby the rotation of the main shaft through intervening mechanism imparts a reciprocating motion to said plunger 13. Positioned in front of and a little to one side of posts 14 and 15 are devices for forming the loops 25 on the ends of the wire 26 in the wooden handles 27. Each of these comprises two gripping jaws on the top of a vertically reciprocating and rotatable post 30, one 28 being round and the other 29 in cross section having substantially the shape of the loop 25, the jaw 29 projecting somewhat above the other jaw 28. Surrounding the upper ends of posts 30 are drums 32 adapted to rotate with said posts, said posts being adapted to reciprocate vertically relative to said drum the jaws on the ends of said posts extending upwardly through openings in the topof the drum, as seen in Figs. 1 and 3, whereby the jaw 29 may be withdrawn to a point level with the top of the drum so that the wire 26 may pass over it and be stopped by the other aw, whereby the return upward movement of the post causes the wire to be engaged between the two jaws.

The posts 30 have a vertically reciprocating motion imparted to them by means of a forked lever 33 pivotally mounted in hangers 34 projecting outwardly from the under side of the machine frame, one end operable by a spring 74 and held out of action periodically by a cam 35 on the main shaft and the forked ends provided with dogs taking loosely into grooves 36 in sleeves 37 secured to the lower extremity of the posts. The

said posts are rotatable by means of pinions 38 loosely mounted on said posts, and racks 39 secured to a longitudinally reciprocating plunger 40, said pinions rotating idly upon said posts except when lifted into locking engagement with clutch members 41 on the posts. The pinions are lifted into locking engagement with said clutch members by means of a forked lever 42 pivotally mounted in hangers 34 one end operable by a spring 75 and held out of action periodically by a cam 43 on the main shaft and the forked ends provided with dogs 44 taking loosely into grooves 45 in sleeves 46 rigidly secured to the posts. The plunger 40 is reciprocated by means of a lever arm 47 rigidly secured to a rocking shaft 48 mounted upon the machine frame, said lever arm terminating in an antifriction roll 49 taking loosely into a socket or recess formed by two uprights 50 secured to the top of said plunger. The rock shaft is operable by means of a link 51 pivotally connecting one end to an arm 52 rigidly secured to the end of the main shaft 11 and the other to an arm 53 rigidly secured to said rock shaft 48. The drums 32 are held against accidental rotation in the wrong direction by means of spring controlled locking devices 54 pivotally mounted upon the frame, one end projecting in grooves 55 in the side of the drums, said locking bars being held under yielding tension by springs 56 attached one end to the free ends of said bars and the other end to some rigid part of the machine frame. An adjustable lug 57 limits the backward movement of the drum locking devices.

The ejecting mechanism.Secured to a sleeve 58 mounted on rock shaft 48 is an ejecting lever comprising forked arms 59 adapted to project forwardly, and clamping arms 60 spaced apart above said forked arms and extending laterally relative thereto. The sleeve 58 is held under constant tension. tending to rotate it in a direction to throw the ejecting lever upwardly by means of a spring 61 one end attached to a flexible strap 62 secured to said sleeve and the other end to a lug 63 on the frame of the machine. The ejecting lever is returned to ready position by means of a rod 64 pivotally attached to sleeve 58 and operable by an arm 65 on plunger 40, the arm in its forward motion sliding on the rod and striking against a lug 66 on said rod. A spring 67 interposed between said lug and said arm forms a yielding adjustment therefor. The ejecting lever is locked against untimely release by a spring 68 having a dog 69 on the end thereof taking into a groove 7 O in sleeve 58, said dog being automatically and periodically disengaged by a moving part of the machine, as upright 50 on the plunger 40, striking against a depending arm 72 on the under side of the spring unlocking the sleeve which is immediately thrown upward by spring 61 ejecting the completely formed carrier.
