SPECIFICATION forming part of Letters Patent No. 414,410, dated November 5, 1889. Application filed August 22, 1889- Serial No. 321,583. (No modeL) To all whom it may concern:

Be it known that I, ALBERT HENLEY, of Lawrence, in the county of Douglas and State of Kansas, have invented a new proved BaleTie lowing is a full, clear,

The objectof the invention is to provide a new and improved machine which is simple and durable in construction, very effective in operation, and specially designed to manufacture bale -ties of wire for baling hay, straw, &c.

The invention consists of certain parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Fig. 6 is an enlarged sectional side elevation of the same on the line .2 2 of Fig. 3, looking in the direction of the arrow 2'. Fig. 7 is an enlarged plan view of the tail-piece of the machine. Fig. 8 is a transverse section of the same on the line 10 w of Fig. 7. Fig. 9 is a like view of the same on the line i" v of Fig. 7. Fig. 9 is a detail perspective view of the mechanism for sliding the shaft N Fig. 9. Fig. 10 is a similar view of the same on the line a u of Fig. 7. Fig. 11 is an end elevation of the same. Fig. 12 is an enlarged transverse section of the cylinder, and Fig. 13 is an enlarged end elevation of the feed-rollers.

The improved bale-tie machine is provided with a suitably-constructed frame A, on one end of which is mounted a head B, and on the other end is held a tail-piece 0, between which and the said head B is held the cylinder D, carrying the bale-tie during the process of twisting one end thereof. On the head B is mounted to turn in suitable bearings the main driving-shaft E, carrying the usual pulleys connected by belts with other machinery for imparting a rotary motion to and Im-' Machine, of which the fol-' and exact description.

the said main driving-shaft E. On the latter is secured a grooved feed-roller F, above which is located a similarlygrooved feedroller F, and between the two feed-rollers is passed the wire G to be formed into a baletie. The feed-roller F is secured on a shaft F which carries a gear-wheel F adapted to mesh into a similar gear-wheel F secured on the main driving-shaft E, so that when the latter is rotated the two feed-rollers F and F travel together and move the wire G forward. The shaft F is mounted to turn in suitable bearings formed on a frame F, pivoted at one end, at F to the frame of the head 13. In the frame F is also formed an aperture F through which passes the wire G, and as the frame F is mounted to swing itcan be swung upward, so that the wire G is moved out of contact with the feed-roller F on account of passing through the aperture F of the said frame F, whereby a forward feeding of the wire ceases.

On the outer E is secured a gear-wheel E, which meshes into a larger gear-wheel E mounted to turn on a stud E secured on an arm E fulcrnmed on the main driving shaft E and provided with a bolt E adapted to be secured in any desired position in the slotted segment E held on the frame of the head B. The larger gear-wheel E carries on one face a pinion E meshing into a gear-wheel E fastened on a transversely-extending shaft H, mounted to turn in suitable bearings in the frame of the head B. On this transversely extending shaft H is secured a cam-wheel H, (see Fig. 6,) on the periphery of which rests the free end of the frame F, so that when the shaft His rotated the said cam-wheel H alternately raises and drops the free end of the framcF whereby the feedrollers F and F are alternately thrown in and outof contact with each other. During the time the feed-rollers are thrown out of contact the wire G remains at a standstill, and during the time that the feed-rollers remain in contact the wire G is fed forward, as previously described. The speed of the shaft H can be increased or diminished by placing a differentsized pinion E on the arm E" and changing the latter accordingly on the slotted segment E The wire G, before passing into the frame F and to the grooved rollers F and F, passes througha se end of the main driving-shaft 1 ries of vertically-arranged friction-rollers I and a series of horizontally-arranged frictionrollers I.

On the transverse shaft H is secured a bevel gear-wheel H meshing into a bevel gearwheel H secured on the longitudinally-extending shaft H mounted. to turn in suitable hearings in the frame A and extending from the headB to the tail 0. The shaft H operates the mechanism J (see Fig. 5)for turning the cylinder D one quarter-turn at certain intervals. The mechanismJ is provided with an almond-shaped cam'J, secured on the said shaft and operating on a lever J fulcrumed at one end to the main frame A. The free end of thelever J is pivotally connected by a link J 3 with a crank-arm J fastened 011 one end of the shaft J 8 of the cylinder D. A spring J 5 is also connected with the free end of the lever J and serves to press the said lever into contact with the periphery of the almond-shaped cam J. On the crank-arm J 4 is held a spring-pawl J", adapted to engage one of four notches formed in a disk J secured on the shaft J of the cylinder D. The notched disk J is adapted to be engaged by a spring J serving to hold the cylinder D in the proper position until turned by the return movement of the. mechanism J. When the shaft H revolves, the cam J acts on the lever J and throws the latter outward, so that a swinging motion is imparted to the crank-arm J whereby its pawl J 6 turns the disk J and the shaft J 8 of the cylinder D is turned one quarter-turn, the spring J 9 dropping at its free end into the next following notch. During the other half-motion of the cam J the pawl J 6 rides over the disk J which latter is held in place by the spring J The shaft H also imparts motion at the proper time to the cutting mechanism K, provided with two knives K and K located opposite each other, and of which the knife K is stationary, being held in suitable bearings in the frame of the head 13. The other knife K is held in a frame K mounted to swing on the frame of the head B, and provided with an arm K resting on the periphery of the cam K secured on the shaft H. A spring K presses against the frame K so as to hold the arm K of the latter in contact with the periphery of the cam K When the latter is in the position shown in Fig. 4, the knives K and K are apart and permit the free discharge of the wire G. however, turns, the arm K is swung outward by the cam K so that the frame K swings on its fulcrum and moves its knife K toward the knife K so that the wire G between the knives K and K is cut. During this operation the feed-rollers F and F are out of contact with each other, and the wire G remains stationary. The knives K and K are preferably held adj ustably in their respective bearings by suitable bolts or other means, so as to sharpen the knives whenever necessary and to compensate for the wear on the sharp edges of the knives.

The cylinder D, into which the wire G is fed, is provided with four longitudinally-extending arms D, each provided on its outer edge with a groove D extending longitudinally and adapted to receive the wire G. Each ,groove D is covered by a plate D held to slide on the outer end of each arm D and secured in place by a series of bolts D passing through inclined slots D in the said plates D held a pin D, adapted to engage a cam D secured on the main frame A, and serving to shift the cover-plates D when the respective arm D is in its lowermost position, so as to uncover the respective groove'D to permit the dropping out of the wire, as is plainly shown in Fig. 12. When the lowermost arm D again moves upward on the turning of the cylinder D, the cam D again shifts the respective cover-plate D until the respective groove D is again closed.

The wire fed into the cylinder D projects a suitable distance-about six inchesand passes through a clamping device L to a bending device N and a twisting device 0, which double theouter end of the wire to form a loop G and a twist G in the wire G, as shown in Fig. 2. The three devices L, N, and O are located on the tail 0 and are actuated from the shaft H previously mentione The clamping device L (see Fig. 10) is provided with a bent lever L, fulcrumed at L I11 the middle of each plate D is on a bracket C secured on the frame 0 of the tail 0. One end of the lever L is provided with an inwardly-extending offset L adapted to'clampthe wire G on a fixed anvil L formed on the bracket'C The other end L rests on the periphery of a cam L'gsecured on the shaft H so that when the latter is rotated the lever L is swung and its projection L moves inward and downward, clamping the wire G on the anvil L The bending device N (see Fig. 9) is provided with a disk 'N, from which projects a crank-pin N adapted to double up the end of the wire projecting beyond the cylinder D. The disk N is secured on a shaft N mounted to turn and to slidein suitable bear ings formed in the frame 0 of the tail 0. On the shaft N is held to turn and to slidea gear-wheelNfl meshing into asegm ental gearwheel N fastened on an arm N fulcrumed on the tail-frame C. Near the middle of the arm N is held a pin N engaging an elliptical cam-groove P, formed in the cam P, fastened on the shaft H WVhen the latter is rotated, said cam P imparts a swinging motion to the arm N so that its segmental gearwheel N turns the gear-wheel N forward and backward, whereby the shaft N with its disk N, is turned for doubling the wire end. The shaft N 3 is mounted to slide transversely, so

as to disengage the pin N from the doubled the loop is made. Forthis purpose,

end after the mechanism Q is provided, comprising a grooved collar Q, secured on the rear end of the shaft N and engaged by one end of a lever Q fulcrumed on the tail-frame O,and engaged at its other end bya cam Q secured on the shaft H". A spring Q serves to hold the lever Q in contact with its cam Q. hen the shaft 11* is turned, the cam Q imparts a swinging motion to the lever Q whereby the collar Q is moved. transversely, and a similar motion is imparted to the shaft N so that the pin N is drawn out of contact with the wire G.

The twisting device 0 operates in conjunction with the bending device N,'and is provided with a pin 0', located in front of the pin N which latter bends the end of the wire G over the pin O when the disk N is turned; The pin 0 is secured on a shaft 0 extending longitudinally and mounted to turn in suitable bearings on the tail-frame C.

On the shaft O is secured a pinion 0 (see Figs. 7 and 8,) in which meshes the segmental gearwheel 0', fastened'on an arm 0 fulcrumcd on the tail-frame O and provided with a pin 0, engaging an elliptical cam-groove 0 formed on one face of the cam Oisecured. on the shaft H. \Vhen the latter is rotated, the cam O imparts a swinging motion to the arm 0 so that the segmental gear-wheel 0 turns the gear-wheel 0 forward and backward, whereby the pin 0, having holdof the loop of the bent wire, forms the twist G" when the shaft 0 turns in one direction. WVhen the shaft 0 is at the end of its movement in one direction, the pin O stands downward, so that the loop G of the wire G can drop 01f of the pin 0', after which the shaft 0 is returned to its former position.

At the end of thetail C is located a registering or counting device R, provided with a bevel gear-wheel R, secured at the end of the shaft H and meshing into a bevel gear-wheel R fastened on the transverselyextendin g shaft R mounted to turn in suitable bearings on the tail-frame C.

On the shaft R is securedaworm R meshing into a worm-wheel R mounted to turn on a stud secured on the tail-frame C. On the outer face of the said worm-wheel R is held a cranlcpin R, adapted to engage a pin S, fastened on a lever S,fulcrumed at its upper end on the tail-frame O and pivotally connected at its lower end by a link S with alever S fulcrumed on a shaft T, mounted to turn in suitable hearings on the frameA and extending longitudinally under the cylinder D, as is plainly shown in Fig. 2. The other end of the lever S carries a spring-pawl S engaging a notched disk secured on the said shaft T and held in place by a spring T as is plainly shown in Fig. 11. A spring S presses on the lever S to hold the same in an innermost position. v

011 the shaft T are secured two or more sets of hubs carrying radial arms U, adapted to rethen passes between the feed-rollers F and F,

which feed the wire forward past the knives K and K in the groove D 011 the uppermost arm D of the cylinder D. The wire G passes through the entire length of the cylinder D and projects at the tail 0 about six inches. At' this moment the cutting mechanism K cuts off the wire by means of the knives K and K and at the same time the frame F is swung upward by the action of the cam H on the shaft H, so that the wire G remains at a standstill. The piece of wire held in the cylinderD now turns with the latter, said cylinder making one quarter-turn by the action of the turning device J, previously described. The projecting end of the wire in the cylinder D and tail O now passes onto the top of the pin N of the disk N, and at the same time the shaft 0 turns, so thatv its pin 0" passes over the projecting end of the said wire, as is shown in Fig. 7. The disk Nnow turns so that the pin N bends the wire over the pin 0' and passes the end of the wire between the lever L and the anvil L onto the wire already on the anvil L as shown in Fig. 10. The cam L now acts on the lever L, so that the offset or foot L clamps the two parts of wire onto the anvil L The mechanism Q, after imparting a transverse sliding motion to the shaft N is now actuated by the cam Q so that the said shaft N slides rearward and the pin N is disengaged from the doubled-up end of the wire. to the shaft 0 from the shaft H by means of the cam 0 the arm 0 the segmental gearwheel 0 and the pinion 0 so that the pin 0' twists the end of the doubled wire, so as to form the loop G and the twist G (Shown in Fig. During this time a new piece of wire G fed into the top arm of the cylinder 1) is cut off by the cutting mechanism K, and a quarter of a revolution is again imparted to the cylinder D, so that the first finished wire passes with the arm 1) of the cylinder Dinto its lowermost position, and during this quarter movement of the cylinder D the cam D opens the cover-plate D, so that the finished bale-tie drops out of the arm D and falls between two corresponding radial arms of the sets of arms U. The above-described operation is then repeatedthat is, the wire is fed into the uppermost arm, cut oif, the cylinder is turned one-quarter of a revolution, the loop and twist G and G of the cut-off wire in the cylinder D are formed, a new piece of wire is inserted into the top of the cylinder, and the lowermost finished bale-tie is dropped out of the cylinder, as above described.

The registering device R is so arranged that the sets of arms U remain in position until,say, one hundred bale-ties have been dropped between two corresponding arms.

A rotary motion is now imparted Then the pin R acts on the pin S, so that the lever S actuates the lever S which latter, by means of its spring-pawl 8*, turns the shaft T so as to bring the next following set of arms U directly under the cylinder D. Thus one hundred bale-ties are always placed between the corresponding arms U of a set and dropped simultaneously on the floor or are otherwise removed from the said arms.
