DEVICE FOR FORMING WIRE BALE-TIES.

SPECIFICATION forming part of Letters Patent No. 507,642, dated October 31, 1893.

Application filed January 19 1893. Serial No.- 458,967- (No model.)

T0 at whom it may concern.-

Be it known that I, ALEXANDER S. ALLEN, of Troy, Rensselaer county, New York, have invented a new and useful Improvement in Machines for Manufacturing Wire Bale-Ties, of which the following is a specification.

In Letters Patent No. 466,563, granted to John Wool Griswold January 5, 1892, there is described a form of adjustable bale tiewhich consists substantially in a wire band having at one end an eye formed by twisting the wire back upon itself, within which eye is received a V-shaped saddle of metal. In operation, the wire band is placed around the bale when said bale is in the press, and the free end of the band is inserted through the saddle in the eye, and drawn tight. The running endv of the band thus becomes jammed in the angle or V of the saddle, and the expansion of the bale, when released from the press, causes the contraction of the eye and hence approximation of the arms of the saddle, whereby the running end of the band becomes still more tightly clamped and grasped.

In Letters Patent N 0. 418,456, granted December 31, 1889, to Frank B. Griswold, there is described a machine for producing, upon the end of a piece of wire, an eye by bending. over the extremity of said wire and twisting the said parts together.

My present invention consists in an improvement in and upon the machine described in said Patent No. 418,456, whereby said machine is enabled to make the device which is set forth in said Patent No. 466,563.

In the accompanying drawings, Figures 1, 2 and 3 illustrate so much of the machine of Patent No. 418,456 as is modified by my invention and as is necessary for the performance thereof; it being understood that the rest of the machine is substantially the same as is illustrated in said Patent No. 418,456. Figs. 4 and 5 represent the device of Patent No. 466,563, which device, as already stated, is made by the apparatus illustrated in Figs. 1, 2 and 3. In Fig. 1 is shown the position of the wire and the parts of the machine before the dog rises to bend the wire over the fixed pin. Fig. 2 shows the position of the wire and the parts of the machine after the dog has risen and bent the wire over the fixed pin. Fig. 3 shows the position of the wire and the parts of the machine after the dog has descended upon the wire to form the eye, and after the eye so formed, which embraces the saddle, has been received and squeezed in the V-shaped notch in the projection on the under side of the dog. Fig. 4 is a front View of the Griswold bale tie and Fig. 5 is a side view thereof.

Similar letters and figures of reference indicate like parts, and the literal references in my present application correspond to those Which appear in said Letters Patent No. 418,456.

38 is a rod having a longitudinal to and fro motion in the manner described in said Letters Patent No. 418,456. The end of said rod 38 enters and is pivoted in a mortise in.a vertical bar, 46, upon which bar, below the pivot, is secured the bending, dog 47. This dog has a rounded downward projection at its extremity 48; and also upon said dog, on its under side, is the cam projection 49.

37 is a flat, projecting head supported upon a friction disk, 36, and carried by a spindle, 39, to which, by suitable gearing, an intermittent, rotary motion is imparted by mechanism which is not here shown, but which is fully described in Letters Patent No. 418,456, hereinbefore referred to. Bolted to the plate 37 is a fixedoam, 50. When the parts are in the position shown in Fig. 1, the dog 47 rests upon said cam 50, and is retained between the plate 37 and a similar plate, 51, outside of said cam. In the upper front portion of the dog 47 there is a longitudinal score (not shown), on opposite sides of which project upward pins, one of which is shown at 52. Supported upon the upper portion of the bar 46 is a downwardly-bent plate, 53, which is slotted and secured by a set-screw, 54, passing through the slot so that the vertical portion of said bar maybe adjusted nearer to or farther from the extremity of the bending dog 47. Projecting from the l1ead'37 is a forming-pin, 57.

The aforesaid parts operate in the manner set forth in Patent N 0. 418,456 as follows, and constitute a device for bending back upon itself the end of the wire A upon which the eye is to be formed. The wire A being introduced under the forming-pin 57, passes between the pins 52 on the dog 47 until its end reaches the stop 53. The wire then lies in the groove on the upper side of the dog 47, and the distance to which it extends over the dog is limited by the position of the stop 53, which is adjusted in the manner already described. By the mechanism set forth in Patent No. 8,456, the rod 38 is caused to move toward the left of the drawings. As it so moves, the cam 49 on the under side of the dog 47 meets the incline of the fixed cam 50,

supported on the head 37, and rises over said cam. As it rises, it carries up with it the end a of the wire which is beyond the forming-pin 57; sothatthis end of the wire assumesfirst a vertical positionand then is bentbackzowvard overthe pin .57, the end 48 of the dog i finallyriding overthe loop and the parts as suming-the position as shown; in Fig. 2. *In order now to form the eye, the rod 38 conitinues to move outward, andthe lower end thebar46 meets an adjustable stop, 58, on

the side of the fixed cam 50; and aS 'LhG bar 46 continues to be pressed against this it stop, the extremity, 4.8, of the dog is forced clownward so as to bring-the bent-overpart of the 0 wire into proximity to the standing part, as shown in Fig. 3. 1 will now describe how theparts, operat- .ing in the manner before described, manufaci ture the bale tie represented in :Figs. 4 and 5. 5 t The said tie consists of-an eye, B, formed on the end of the band, which eye B receives a V-shaped saddle, C, which is preferably made i i of wrought metal. Onthe outside of the saddle formed by bending the edgesthereof to- 40 gether is a groove, D, in which groovethe wire ofthe eye B lies. It will be seenthat I have changed the shape of the forming-pin 57 from a 2 that which is shown in Patent No.418,456, to a pin of triangular cross-section which is adapted to receive upon it the saddle O. This saddle is placed in position upon the pin 57 i by hand before the wire A is introduced into i the machine, as shown in Fig. 1.

i It will be evident from Fig. 2that the operation ofvthe dog 47 is, while bending the .wire A around the pin 57, likewise to carry a said wire snugly into the groove of the sad- ..tdle C. It is,however, necessary that thesad- -dle should be forced down tightly against the i wire at the end of the eye; for I have found, t by actual experiment with these baleties, i that when such is not the case, the saddle is liable to become rupturedunder heavy strain;

this beingdue to the fact that it isnotprop 6o erlysupported orbacked by the wire. I therefore provide, on theunder side of thedog 47,

aprojection, E, in which projection there is a V-shaped recess, F. This recess is so constructed and disposed that when the parts 6 5 reach the position shown in Fig. 3, the pin57 the saddle O thereon and the wire A (now bent over said saddle) will all be received in said recess F, and the remaining additional forward movement of the rod 38 causes the wire A and saddle C to be closely jammed or pressed together between the pin 57 and the sides of the recess F. In this way the wire is closely and snugly forced into the groove D on the saddle C; and also in the manner already described, the end 48 of the dog presses the wire in rear of the fastening pin downward so as to form the eye, as indicated in Fig. 8.

The remaining operation of the machine to effect the twisting of the eye is exactly the same as is described in said Patent No. 418,45 6, and therefore needs no further description.

I claim 1. The combination: in amaehinefor the manufacture ofbaletiefastenings of thertype hereinbeforedescribed, of a fixed supportconstructed to receive the thimble orwsaddle of the eye, means for bending the'wire around said saddle,and means for twisting the approximated parts of the wire togethertoform said eye, substantially as described.

2.The combination in a machine for the manufacture of baletie fastenings of thetype hereinbefore described, of a fixed supportconstructed to receive the thimble or saddle of hereinbefore described, of a fixed V-shaped pin or support 57 adapted toreceivethesaddle O, mechanism for bending the wireA around said support to forum an eye B, anda=reciproeating block E havinga V-shaped opening F adapted to receive said supporthntermittently movingvupon the same and thereby compressing the wire of eye B into the-groove D of the saddle 0,,substantially as described.

4. The combination in a wire-bending machine, of a fixed pin of wedge-shaped crosssection 'aroundwhich-the wireis bent,a:dog swinging in a vertical plane and also: having atitscenter of oscillation a reciprocating motion toward and from said pin, a projection on one sideof said dog having a wedge 01' V-shaped recess turned toward and adapted to receive said pimand a fixedcam :placed beneath: said dog andn'egulating its upper throw; the aforesaid parts beingarranged and operating so that when a wire is i ntroducedunder said pin and over said dog, the

"forward motion of said dog" over saidcam shall cause said dog to rise and to carry and bend said wire over said pin, and the continuing forward movement of said dog shall cause the recess in said projection to receive: the

said wire 100p and compress the same upon F adapted to receive said pin 57, substansaid pin. tially as described.

5. The combination of the rotary head 37 and the wedge or V-shaped forming-pin 57 ALEXANDER ALLEN 5 and fixed cam 50 thereon, the movable rod 38 Witnesses:

and dog 47 pivoted thereto, and on said dog FRANK B. GRISWOLD, the projection E having the V-shaped recess W. W. RoUssEAU.
