SPECIFICATION forming part of Letters Patent No 639,467, dated December 19, 1899.
Application filed August 3, 1897. Serial No. 646,872. lllo 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.
The object of my invention is to provide a machine for making bale-ties continuously and automatically from a continuous length or reel of wire, the wire being cut into bale lengths and looped and twisted complete at each end before being discharged from the machine.
The fundamental parts of my new machine consist of an endless traveling belt, chain, or
other carrier and chucks mounted, by preference, in pairs on said belt or chain, a wirecutter being arranged to sever the wire at a point between said chucks. I prefer to employ three pairs of chucks connected in the same belt, chain, or carrier a bales length apart and arranged so that they will take the wire from the reel at the beginning of the upper part of the circuit, each succeeding rear chuck being adapted to grasp the main length of wire before the preceding one releases it, so that at no time during the operation is the main length of wire entirely released, and I construct each pair of chucks to fold each end of the wire in opposite directions, both in a direction away from the interposed cutter. In the preferred construction one of each pair of chucks is constructed to fold and twist the loop ends of the bale-ties, while the other is constructed to fold, twist, and form up the anchor ends, both performed simultaneously and while the chucks are traversing the 40 upper half of their circuit.
My invention consists in the general principles, construction, and operation of a machine as above outlined and in the special construction, arrangement, and combinations of parts, all as hereinafter described and claimed.
In the accompanying drawings, to which reference is made and which form a part of this specification, Figure 1 is a sectional elevation of a bale-tie machine made in accordance with my invention. Fig. 2 is an enlarged longitudinal sectional elevation of one pair of sections or chucks, showing the parts thereof in the position they assume when ready to receive the wire. Fig. 3 is a plan view of the same. Fig. 4 is a central longitudinal sectional elevation of the same, showing the parts in the position they assume just before the two adjacent ends of the main length and one bale-wire are bent. Fig. 5 is a like view showing the parts in the position they assume after the ends of the wires are bent and be- I fore the twists are formed. Fig. 6 is a de-' tailed view of the wire-cutter and allied parts. Figs. 7 and 8 are respectively end and side elevations of one of the wire-twisters removed from the machine. Fig. 9 is an end view of the folding bar orshaft with the sliding bar and folding-arm removed. Fig. 10 is a plan view of the sliding folding bar and arm removed.- Fig. 11 is an edge view of the same. Fig. 12 is a plan view of the shaft and folding-arm for forming the anchor end of the wire. Fig. 13 is a plan View of the sliding plate removed from said folding-shaft. 14 is an end view of the said shaft and folder with the sliding bar and plate removed. Fig. 15 is a detailed side view of the said sliding bar. Fig. 16 is a plan viewin section and diagram, illustrating the frame for a single-wire machine and the parts which operate the mechanism of the sections or chucks. Fig. 17 is a detailed side elevation of the gather ing device for the twisters. Fig. 18 is a detailed sectional elevation of the hook or anchor folding and forming arm. Fig. 19 is a plan view of the hook oranchor end of a balewlre.
Speaking in general, explanatory particularly of the general diagram of the machine as shown in Fig. l, 2 represents an endless chain or belt which passes over sprocketwheels 3 3, attached to shafts 4. 4, one of which shafts may be provided with a powerpulley 5 for operating the machine. In the said chain 2 are connected in place of links three pairs of sections or chucks, one chuck of each pair being constructed to form the loop Fig. 75
a shaft or rod 8 to allow the chucks to conform to the circumference of the sprocketwheels and to cause the wire coming froma reel (not shown) through a straightener or feed-tube 9 to be taken by and drawn down into the chucks at the time each pair of chucks pass up over the upper crest of the front sprocket-wheel.
Each loop-chuck 6 is provided with a wire grip or clamp 10, described hereinafter in detail, for grasping the wire at the time it reaches the horizontal position at the top of the front sprocket-wheel, and each anchorchuck 7 is provided .with a wire-cutter 62, arranged to cut the wire in proper lengths for bale-ties, where it lies in the space between the two chucks, the time of such cutting being after the succeeding clamp has fully grasped the main incominglength of wire, so that at no time during operation is the main length of wire released from the grasp of both of the clamping devices 10 on the successive loop-forming chucks.
Each of the loop-chucks is provided with a folder 51, which, after a cutter 62 has severed the wire, folds the severed end back upon the main body of the wire and down into a twister 14, while each of the anchor-' chucks is provided with a-folder or foldingshaft 68, which folds the end of the short length of wire that is, the portion cut off to bale length-over upon itself and down into a twister 16. Each loop-clutch is also provided with a lip or plate 52, Fig. 11., over which the folder 51 bends the wire and up to which the twister 14 twists the wire to form the loop.
The folder 68 of the anchor-chucks operates in conjunction also with means for forming the anchor or hook, one portion of which latter is a plate 17, Figs. 12 and 13, (not shown-- in Fig. 1,) around and up to the edges of which the twister 16 twists the wire.
Following the above general outline, I shall now describe in detail one of the duplicate loop-chucks and then in detail one of the anchor-chucks, which will be sufficient to enable others skilled in the art to construct and operate the machine, preinising that I do not confine myself to the details in construction here shown, for I am aware that the parts and the form of construction may be variously changed and still embody the principles and essential features of my invention.
Each loop-chuck 6 has two side or cheek pieces 20, Figs. 2, 3, 4, and 5, formed with eyes 21 at each end to receive the rods 8 and 22. A bolt 23 and clamp-nuts 24 24 on the shafts 8 and 22 clamp the cheek-pieces firmly together.
25 represents a plate at the ends of the cheek-pieces 20, which is formed with a horizontal flange 26 at its bottom edge and with an open slot 27 at its upper edge to receive the wire. Bolted to the face of the plate 25 are two plates 28 29, which are spaced by in terposed blocks 30, which form the fixed or stationary jaws of the clamp for the wire.
31 is the moving jaw of the clamp, pivoted on a bolt 32, Figs. 3, 4, and 5. The lower end of the jaw 31 is bifurcated to engage with a stud 33, secured in a plate 34, which slides in a way formed by the above-mentioned flange 26 and the plate 29, as shown clearly in Figs. 2 and 3.
35 35 represent two pillow-blocks bolted to the edges of the cheek-pieces 20 20. These are spaced, as shown clearly in Figs. 2 and 3, and are slotted, as shown at 36 36, in line with the slot 27 in the plate 25. The said pillowblocks form journals for the twisting-spindle 37, (see Figs. 7.and 8,) which is formed with a longitudinal slot 38 and provided with a gear wheel or pinion 39, which is formed with a slot 40 coincident with the said longitudinal slot 38 to admit the main length of the wire down into the slot 38 to a point at or below the longitudinal axis of the said spindle and also to allow the end of the wire after it has been folded back by the folder to be likewise forced down into the slot 38. The pinion 39 is rotated by a Worm 41 on the transverse shaft 42. The front end of the spindle 37 is provided with an offset and slotted flange 43, connected to an off-center hub 44, so that when the main wire and its folded-back end are held in the slot and the spindle is rotated the plate 43 revolves eccentrically around the axis of the spindle and twists both wires together.
On the off-center hub 44 is placed a gathering device 45, which in the revolution of the twister operates to close the folded-back end of the wire snugly down into the slot in contact with the main length .of the wire, so that a perfect twist will be formed. This gather ing device consists in the main of an arm or plate 45, formed with an eccentric aperture 45 (see Fig. 17,) one portion thereof bearing concentrically on the hub 44. The eccentricity of the aperture 45 forms an open recess 45, into which the two parts of the wire are carried at the outset of the revolution of the twister. The remainder of the recess forms a gathering or centering cam 45 which in the first complete revolution of the twister forces the two parts of the wire to the center of the twister, which causes the latter during the completion of its given number of revolutions to twist both parts of the wire properly and reliably together.
The above described operation of the twister, as is evident, takes place just subsequently to the operation of the folder now to be described.
The folder comprises a shaft 46, held to make a one-halfrevolution back and forward in spaced pillow-blocks 47 47, secured to the cheek-pieces 20 of the loop-chuck. The shaft 46 is formed with transverse slots 48, which reach practically to its diameter. The said shaft is also formed with a longitudinal channel or Way49, in which is placed a sliding bar 50. ing bar is provided with a lateral folding-arm 51, the outer end of which is, by preference, slightly upturned and notched to properly engage with the end of the Wire to be turned back. The said sliding bar 50 is also formed or provided with a lip or plate 52 in line with the folding-arm 51, as shown in Fig. 10, and the size of this plate determines the size of the loop to be formed in the wire. The distance of longitudinal movement of the bar 50 is just sufficient to carry the lip or plate 52 over the wire after it enters the transverse slots 48 in the shaft 46 and in moving in the opposite direction to release the loop. The first movement, as indicated by the arrow in Fig. 10, carries the lip or plate 52 over the wire and at the same time carries thefolding-arm 51 squarely beneath the wire. At this time the shaft 46 and foldingarm 51 are turned back from the position shown in Fig. 4 to that shown in Fig. 5, thus folding the end of the wire over the lip or plate 52 and depressing the end of the wire down into the twister, as clearly indicated in Fig. 5. The twist having been formed, the plate 50 is moved back to its original position, causing the lip or plate 52 to be withdrawn laterally from the loop, and then in proper time the shaft 46 is turned back to its original position ready to operate upon another wire after the chuck has been carried around the circuit of the endless chain.
As thus far described, it will be seen that bar 34 is to be reciprocated, closing the clamping-jaw 31 upon the wire, that the shaft 42 is to be rotated, that the bar 50, with its folding-arm 51 and lip 52, is to be reciprocated, and that the shaft 46, with the bar 50, is to be rotated from the position shown in Fig. 4 to that shown in Fig. 5 and back again all duijng the continuous travel of the endless chain 2. For producing these said movements various practical means may be adopted, and therefore I do not limit myself to the means shown or to any specific means, but desire it to be understood that I claim the loopchuck broadly without reference to the mechanism adopted for moving the parts named above.
As here shown, the bar 34 is reciprocated by a cam 34, (see Fig. 16,) fixed in the main frame of the machine, one end of the said bar being upturned to form a hook 34 for engaging with said cam. The shaft 42 is rotated by a rack 42, fixed in the frame of the machine, the said shaft being provided with a pinion 42" for engaging with said rack. The bar 50 is reciprocated by a cam 50, also fixed in the frame of the machine, and the shaft 46 is rotated in one direction by a rack 46 and (See Figs. 9,10, and 11.) This said slidthe said shaft being provided with a' pinion 46 for engaging with said racks. It is evident that a spring may be employed in place of the rack 46 for returning the shaft 46 and that a spring similar to that shown in Fig. 6 may be employed for the return movement of the bars 34 and 50.
The anchor-chucks have each two cheekplates 55, formed with eyes 56 to receive the shaft 8 and with eyes 57 to engage with a shaft 58. To the ends of the cheek-pieces 55 is bolted a plate 59, formed with a slot 60, Fig. 3, the edge 61 of which constitutes a stationary cutting edge.
62 is the movable shear or blade, which, in conjunction with the cutting edge 61, severs the wire, as indicated in Figs. 3 and 4. This blade 62 is pivoted on a belt or stud 63 and is slotted at its lower end, as shown at 64, to engage with a stud 65, fixed in a laterally-sliding plate 66, so that the reciprocating movement of said plate will operate the blade 62 for properly severing the wire. The plate 66 is moved in one direction by a spring 66 Fig. 6.
In spaced pillow-blocks 67 67 is held a rotatory shaft 68. This shaft is formed on one side with a longitudinal undercut or T-slot 69 (see Figs. 2 and 14) and on the opposite side with a longitudinal channel 70 and with a slot 71 from channel to channel. (See dotted lines, Fig. 12.) The said shaft 68 is also formed with a transverse recess 72, in which latter is held a folding and forming arm or finger 73. The said folding and forming arm 73 is formed with a channel 73, Figs. 12 and 18, and the flanges which constitute the said channel are recessed, as shown at 73", and the said flanges are also formed with a passage 73, into which a plate 17 is adapted to slide over the wire in the channel 73*, .as illustrated in Figs. 4 and 5. The said plate 17 works in the T-slot 69 of the shaft 68 and is operated by a sliding bar 74 in the longi- IIO tudinal channel 70 and a pin 75, which is attached to said bar and which projects through the slot 71, as clearly shown in full and dotted lines in Fig. 12. At the time the wire enters the channel 73 of the folding and forming arm the plate 17 is withdrawn from across the said channel and the said arm is turned back by the shaft 68 to the position shown in Fig. 4. As soon as the blade 62 severs the wire the shaft 68 and arm 73 are turned to the position shown in Fig. 5, thus causing the folding and forming arm to fold the end of the wire over the plate 17 and at the same time depressing the end of the wire down into the twister 16. This, it is evident, forms a loop in the wire, but does not shape the hook or anchor to the form illustrated in Fig. 19, which it is desirable to do. For thus shaping the hook or anchor the recess 73 is formed in the folding and forming arm 73, which, acting in conjunction with pawl 76, bends the wire back over the edge of the in the opposite direction by another rack 46*, plate 17 and forms the heel a of the hook or -of the hook or anchor.
It remains, then, to form the belly a This is done by a pivoted forming-blade 77, acted upon by a rotary reciprocating cam '78, secured on the shaft 79, which cam operates to vlift the thin curved edge of the blade 77 after the plate 17 has been withdrawn from the wire, but whilethe wire is still held by the pawl 76.
The pawl 76 is pivoted to a lever 80, which is operated by the said cam 78, the cam being by preference formed with a projection 81, which works in a bifurcation 82, formed in the end of the said lever.
The twister 16 of the anchor-chuck is journaled in pillow-blocks 83 83, is operated by a worm 84, Figs. 4 and 5, on atransverse shaft 85, and is in all respects like the twister 14 of the loop-clutch already described and need not therefore be further described, except to say that it is held in its pillow-blocks in reversed position to that of the twister 14.
- The cheek-pieces of the anchor-chuck besides being formed with the eyes 56 57 are also cast to form a tube 86, which is transversely slotted, as shown at 87, Fig. 3, to receive and to act as a stay to the wire, and to further insure the proper holding of the wire at that end of the anchor-chuck I may provide the tube 86 with a sliding bar 88, slotted and undercut to form a lip 89, Figs. 4 and 5, which is adapted to overlie the wire while the operations are being performed and to be moved back when the wire is completed.
I do not limit myself to any special means for reciprocating the bar 66 for cutting the wire or to any special means for reciprocating the bar 74, or for half-rotating back and forth the shafts 68 79, or for rotating the shaft 85 for turning the twister, or for reciprocating the shaft 88, as various means for these motions may be adopted, all within the scope and spirit of my invention; but as here shown the bar 66 is reciprocated in one direction by anchor.
' a cam 66, fixed in the frame of the machine, (see Fig. 16,)and in the opposite direction by a spring 66 (Shown in Fig. 6.) The bar 74 is reciprocated in one direction bya cam 74, the end of the said bar being formed with a lip 74 to engage with said cam andin the opposite direction by a cam 74. The back-andforth rotation of the shaft 68 is accomplished by two oppositely-arranged racks 68 68 fixed on the frame of the machine, the said shaft being provided with a pinion 68 for engaging with said racks; but a spring may be used in place of the rack 68 for return movement of said shaft. The shaft 79 is semirotated in one direction by a rack 79, the said shaft being provided with a pinion 79 for engaging with said rack, and may be returned by the weight of the cam 78 or other counterweight or by a spring. The twister-shaft 85 is rotated by the rack 42, the said shaft being provided-with a pinion 85 for engaging with said-rack. The bar 88 is reciprocated in one direction by the cam 74 and in the other by the cam 74.
IVhile I have shown my invention in the accompanying drawings as applied for automatically andcontinuously cutting and forming complete the so-called anchor bale-tie and for this purpose adaptedfor operation with a single wire, it will be understood that the chucks in their form of construction are adapted for duplication in and with duplicate belts, chains, or carriers to any desired number running side by side, so that I am enabled to construct a seriesmachine to run automatically withas many wires as there may be series of chucks in the machine, and I shall find it practical with such a machine to run from twenty-five reels or bundles of wire, making three times as many bale-ties with each complete revolution of the endless chain; nor do I limit myself to the use of chucks in pairs, as single chucks may be used, leaving one end ofthe bale-ties straight; nor do I limit myself to the anchor or any special form of loop at the end or ends of the bale-ties.
