BALE-TIE MACHINE.

SPECIFICATION forming part of Letters Patent No. 639,466, dated December 19, 1899. Application filed July 15, 1897. Serial No. 644,621. (No model.

To (all whom it may concern.-

Be it known that I, EDGAR M. TOUSLEY, a citizen of the United States, and a resident of Jamestown, in the county of Chautauqua and State of New York, have invented certain new and useful Improvements in Bale-Tie Machines, of which the following is a specification.

This invention relates to a machine for to manufacturing the so-cailed anchor or cross-head bale-ties; and the invention consists of a machine wherein the bale-wires are subjected to the action of folding mechanism and then to the action of twisting mechanism arranged in connection with folding mechanism, the latter being adapted not only to fold the wire, but to place the wire in the twisting mechanism.

The invention also consists in means for forcibly expelling the completed bale-wire from' the machine, in the construction of the twister,- and in the construction, arrangement, and operation of the Various parts of the machine, all as hereinafter described and claimed.

In the accompanying drawings, to which reference is made and which form a part of this specification, Figure l is a side elevation, partly in section, of my machine for making cross-head bale-ties. Fig. 2 is a rear elevation of the same, the power-shaft being shown in section. Fig. 3 is a side elevation of the twister, the yoke therefor being shown in sectional elevation. Fig. 3 is a perspective View of the said yoke. Fig. 4 is a front elevation of the twister and yoke. Figs. 5 to 13 illustrate the folding and twisting mechanism and the Various positions and operations of the same from the time the straight wire is placed in the machine until the wire is removed therefrom with a complete hook or anchor formed at one end thereof. Figs. 14: and 15 illustrate the construction and operation of an automatic feed for placing the straight wires into the machine and removing the same after being folded and twisted.

Referring to the drawings, 2 represents the power-shaft, provided with a pulley 8 for rotating the said shaft.

On the shaft 2 is secured a Wheel or disk 4, formed or provided with a segment 5 of cogs for intermittently rotating the twister 6 by means of a pinion 7, formed or secured on said twister. The said twister is journaled in bearings 8 and is substantially cylind rical-that is, as here shown, is cylindrical at its ends 9 and 10 each side of the pinion 7, the said ends being adapted to rotate in the bearings 8. The twister is slotted throughout-that is, the cylindrical portions and the pinion 7 are formed with a longitudinal slot 12 to receive the wire w, as illustrated in Fig. 1, and said slot 12 extends to or "beyond the longitudinal axis of the twister. The cylindrical portion 10 of the twister is formed below the slot 12 with an extension or neck 13, which is provided with a slotted flange or collar 14, the slot 14 of which is of a size relative to the size of the wire to be adapted on the revolution of the twister to carry the end to of the wire around the axis of the twister to form the twist. On the extension or neck 13 and collar 14: is placed a yoke 15, which latter is slotted, as shown at 15, and formed with an eccentric recess 16, which serves when the twister is rotated to center the end w of the wire in the twister, and in order that the said yoke 15 may follow the eccentric rotation of the neck 13 its lower end is slotted, as shown at 15 to work upon a stationary pin 17, as illus- 8o trated in full and dotted lines in Fig. 1. On the power-shaft 2 are also secured the cams l8 and 19, which operate the folding mechanism F, and the cam 20, which operates the finishing-plate f-that is, the plate which forms the curve 10 in the wire.

The cam 18 is by preference of the grooved orchannel type, having a channel 18 formed therein. This cam operates vertically a bar 21. The said baris by preference held in po- 0 sition by having its lower end pivoted to a lever 22, sustained bya bar or shaft 23, held in suitable hangers 24 beneath the main table 25. The upperend of the bar 21 is provided with projections or fingers 26, around or par tially around which the wire is bent to form the curves or eyes 20 of the hook or anchor, as hereinafter described. The bar 21 besides having an up-and-down movement has also a lateral movement to cause the fingers 2G to embrace and release the wire, and this lateral movement is by preference produced by means of a cam 27, formed by bending the bar and passing it through a plate 28 or yoke.

The primary position ofthe bar 21 and its fingers 26 is shown in Figs. 5 and G, inwh'ich position the bar has been raised and brought forward, so that theiingers reach over the wire which has just been dropped into the slot of the twister and folder with its end against the gage-plate 29. From the said position wherever the fingers 26 stand above the straight wire the portion 18" of the cam 18 operates to draw the bar 21 and the said fingers downward to the position shown in Figs. 1 and 7, causing the fingers to draw the wire down into the folding mechanism F--that is, down into the openings or recesses 30, formed in the ends of the right and left eye-folders 31 31. These two eye-folders 31 are geared to operate together in opposite directions by pinions 32, one of which is engaged by a reciprocatory rack The end of the left-hand eye-folder is provided with a lug 34, which in being turned from the position shown in Fig. 5 to that shown in Fig. 7 bends the wire around the adjacent finger 26, as shown in dotted lines in Fig. '7, and shapes the hook of the anchor. The right-hand eye-twisteris formed or provided with a folding-blade 35, which in swinging from the position shown in Fig. 5 to that shown in Fig. 7 folds the wire around the other finger 26 and laps the end to of the wire back upon the main length of the wire and down into the twister 6 and the plate 14 thereof.

As above intimated,the operation of the eyetwister and the folders 34 35 is produced by the rack 33, which in this instanceis pivoted to a lever 36, held by the bar 23 and raised by the cam 19 and forced back by gravity or by a spring 37, the downward movement serving to return the eye-twister and folders 34 35 to their original position, that shown in Fig. 5, ready for another operation when the wire thus folded shall have been twisted and discharged from the machine.

In the operation of twisting it will be noticed that the end w is held in the slot 14 as in the claw of a hammer, and this claw being connected to the twister proper is carried around the central axis of the twister. Now to obviate a misoperation and to cause the twist to be properly formed the yoke 1.5 is employed, the eccentric recess 16 of which serves during the first revolution of the twister to gather the two parallel parts of the wire together in the slot at the longitudinal axis of the twister.

During the time that the folder 35 is swung over upon the wire the forming-blade f is elevated, so that its upper curved edge forms the curve 20 in the wire, as shown clearly in Fig. 9. The said forming-blade is by preference a part of the rod 38 and is reciprocated by the cam 20 and spring 39, the rod 38 being connected to the lever 40, sustained by the rod 23. g

It will be noticed that the plate 28, which in connection with the bend or cam 27 moves the bar 21 and fingers 26 laterally, is connected to the bar 38. I do not limit myself to this arrangement and form of construction, as various means for accomplishing the said lateral movement may be employed, but for the sake of economy and compactness the method shown is preferred. When the bar 38 and forming-bladef are lifted, the bar 21 is moved back away from the wire and the fingers 26 are withdrawn from the eyes w, as shown in Fig. 10, and at the time the forming-plate fis making the bend to the cam 18 causes or allows the bar 21 to descend slightly-that is, a distance equal to or greater than the thickness of the wireand when the bar 38 descends the plate 28, acting on cam 27, draws the bar 21 forward again and .projects the fingers 26 beneath the eyes w of the wire. This done, the cam 18 lifts the bar 21 and fingers 26 and causes the .fingers to forcibly eject the wire from the folding mechanism F, as illustrated in Fig. 13. It will be understood that before or during the lastmentioned upward movement of the bar 21 the rack 33 will return or will have returned the folding mechanism to normal position, so that the machine is ready to receive another wire for another operation.

In order to forcibly eject the wire from the twister, I prefer to employ another wire 1ifting or ejecting device located near the inner end of the twister. This consists of a bar 42, pivoted to a lever 43, (see Figs. 1 and 13,) sustained by the rod 23. A stud 44 is connected to the cam 18, which in the revolution of the cam strikes the lever 43 at the proper time, and thus lifts the bar 42 and causes it to expel the wire from the twister.

In case the automatic feeding device shown in Figs. 14 and 15 is employed the bar 2 may be omitted, the lever 45 serving to place the wires in the machine and also to expel them. The lever 45 is to be located adjacent to the inner end of the twister and reci'procated by a connecting-rod 46, attached to the arm 47 of the lever, and at its lower end to the lever 43. The front end of the lever 45 is formed with two fingers 48 and 49, the latter lower and longer than the former, and the former for feeding the wires one by one from the hopper 50 down into the machine, the latter for lifting them out of the machine.

M The wires are retained in the hopper 50 by a spring 51, which presses against the curved face of the back board 52. A shallow recess 53 is by preference formed in the said curved face of the back board, and a bulge 54 is formed in the spring 51 above the said recess, so that as a wire is advanced by the finger 48 the bulge 54 will close in over it and retain or hold back the pile of wires above. The advanced wire is thus held in the recess 53 and prevented from dropping immediately into the machine by the lower portion of the spring 51.

56 represents a by-pass finger switch or spring which presses against the guide 57 and projects into and across the narrow channel 58, which is both theinlet and outlet channel for the wires. The lower end of the spring 56 serves as a switch to direct the completed wires out of the machine as they are lifted out of the twister and folding mechanism by the finger 49.

It will be understood that by omitting the forming-blade fand the lug 3t and properly shaping the inner edge of the folding-plate 35 the machine would operate to form the loop end of the bale-wire instead of the hook or anchor end, as shown and above described, and it will also be understood that by proper juxtaposition of two of the machines described both ends of bale-wire may be folded and twisted at the same time, thus completing a bale-wire at one and the same operation.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1.
