IMPROVEMENT IN GRAIN-BINDERS.

Specification forming part of Letters Patent No. 222,829, dated December 23, 1879; application filed March 3, 1879.

To all whom t may concern:

Be it known that I, SYLvANUs D. LoeKE, of Hoosiclr Falls, in the county of Rensselaer, in the State of New York, have invented new and useful Improvements in Automatic Binding-Machines and Harvesters, of which the following is a full and exact description.

This improvement relates to the twisting, holding, and cutting devices that sever and hold the ends of the wire and secure them to gether around the bundle, and for convenience they will be described in connection with the band-carrying and other mechanism of an au tomatic binder which form the subject-matter of separate Letters Patent, and for which I make no claim in this patent.

The object of my present improvement is, primarily, to secure intermittent rotary movement of both twister and cutter and holder in the same direction, but with different intervals of rotation and rest, and to perform these various and intermittent operations in the simplest and most economical mannerto wit, by the employmentof parts that are duplicated by casting and need'no fitting as to their working parts; and my invention consists, first, in the peculiar and novel construction and operation of a wheel, pinion, and a twister having opposing and radial leaves or hooks, whereby the continuous movement of the wheel during revolution shall, by means of gear-teeth and stop-plates alternately disposed on the Wheel and also on the pinion, and preferably cast thereon, give to the twister first a halfrevolution, then an interval of rest, and then several revolutions, followed by a second interval of rest, during each full operation of the binding machine, thereby enabling the twister itself to dispose the two ends of the band on the opposite sides of its axis, and then to twist them together, after which it is withdrawn and securely held out of the field of entanglement with the grain or band .material during the time they are being presented and adj usted in the machine and until again called to perform its function of securing the ends of the band.

My invention also consists in a similar novel and peculiar construction and operation of a twister, band holder and cutter, and their operating-pinions, with a single and preferably a cast wheel, whereby the various and complicated and intermittent movements and stops of the twister, holder, and cutter are secured by the simple rotation of the wheel, as hereinafter set forth.

My invention also consists in the employment of a looper-preferably a simple piece of l bent wire-underneath the twister, whereby thc ends of the band may be loosened and severed before the operation of twisting them together has proceeded far.

My invention further consists in other details of construction and operation, as herein set forth and described.

That others may fully understand the construction and operation of my improvements, I will particularly describe them, having reference to the accompanying drawings, where- Figure 1 is a transverse section through the binding apparatus, showing the gatheringarms, binding-arm, wire-spool, and twisting mechanism in position. nal sectional elevation of the driving-shaft, representing the twisting mechanism and its driving-gear in position. Fig. 3 is a perspective view of the twisting devices detached. Fig. 4 is a transverse section, same plane as in Fig. 1, but enlarged, and showing the twisting mechanism in operation. Fig. 5 is a longitudinal section of the twisting device. Fig. 6 is an elevation of the same. Fig. 7 is a plan view of the same.

J is the principal shaft, which receives its movement from the prime mover in any suitable way, as by means of a belt or chain passing over the wheel K mounted loosely upon said shaft, and provided with a clutch, L, whereby said wheelV may be locked fast to said shaft, or unlocked therefrom at pleasure..

The binding-head Q, as herein shown, receives its movement from said shaft J, and the gavel, taken from the receptacle of the binder, is carried against the wire,`"partly looping the latter around it by means of the arms M.

The binding-wire is wound upon a spool, d, suitably located upon the machine, and from thence passes to the roller at the end of the binding-arm, and its end is griped by the wireholder.

When the gavel has been raised against the Fig. 2 is a longitudi.

wire by one of the arms M the binding-arm descends, carrying the wire around the gavel and bringing th'e ends of the band together and presenting them to the twister and cutter, whereby' they are twisted together and severed, and the new end again griped, when the binding-arm recedes and the bundle is discharged.

Upon the shaft J there is mounted and attached thereto a wheel or gear, A, of peculiar construction, whereby theA twister and cutter are intermittently caused to operate.

The twister D and cutter E, with their driving-pinions F G, are supported and take bearing in the bracket B, that is bolted to the frame of the machine. The bearing C of this bracket has its axis preferably radial as to the axis of the wheel A.

rIhecutter E is hook-shaped, and extends radially from its hollow shaft or axis. Its upper and under surfaces are hat, and its front upper edge is shaped so as to form a cutter, while the under surface has its front edge rounded and arranged to join the wire between it and the abutment-plate e of the bracket. The shaft of said cutter is tubular or hollow, and extends through the bearing C, and has at its other and lower end a pinion, G, attached thereto. The twister is formed by two hook-shaped arms extending at right angles and in opposite directions from its shaft, which is inserted through and takes bearin g in the tubular shaft of the cutter E, and is terminated at its other end by the pinion F.

A looping-piece, H, preferably a piece of wire, is secured to the bracket B in any suitable manner, as by a set-screw cr belt, h, and its free end extends toward the shaft of the twister, and is curved nearly around the neck of the twister, and at a short distance therefrom, just below the twisting-hooks and between them and the cutter E. After the twister has made a half-revolution or more the ends are severed or loosened, and the object of the part EI is to prevent these ends from escaping from the twisting-hooks while the latter are twisting them together. This object is secured by this part H, which I call a loopen holding the ends close to the neck of the twister and looping or crimping them underneath itself against the cutter-plate below.

The cutter-plate I, the front edge of which should be of hardened steel, -is secured as to one end to the bracket B, and the other end is looped around the neck of the twister and forms a ledge, on which the ends of the band are crimped before being twisted, and the cutter E sheers against the hardened edge of this plate in severing the binding-wire. The pinion G is provided with a cam-projection or stop-plate, g, the outer or workingface of which is fitted to slide upon a circular way that is vturned or cast upon the wheel A, thereby preventing the pinion from turning except at those points where said stopway` is cutaway or depressed for the purpose of permitting said pinion to revolve. The pinion F is provided with two similar cam-projections or stop-plates, f. The stop-plates are at the same radial distance and on opposite sides of said pinion, and have their working-faces preferably parallel with each other and fitted to slide upon another similar stopway on said wheel, thatprevents said pinion from revolving except when it is cut away or depressed for that purpose. I use two stop-plates on this pinion, so as to be able to give the twister D, when required for the purpose of disposing properly the two ends of the band,l only one-half a revolution, and then holding it at rest.

In operation, one revolution of the shaft J and of the wheel A measures, as herein shown, but not necessarily, the time taken in binding a bundle, and it is desired that the twister' shall have imparted to it several revplutions to twist the ends together, and then come to rest and be held in position to receive the ends of the band when properly presented, while the cutter requires only one revolution to cut the band, and thereafter should be at rest and held out of the way of entanglement. The wheel A, therefore, is provided with a series of teeth, a,meshing with the pinion F, extending a portion of the way around the wheel, and these teeth arc sufiicient in number to give said pinion preferably three or four revolutions, and are arranged in connection with the stopway 7c and the teeth and stop-plates of pinion F, so as to rotate the pinion with the twister while the band is being secured, and to prevent them from turning while the other operations of binding are being performed, or at least while the ends of the band are being presented to the twister. The wheel A is also provided with a set of teeth, c, which in practice are, or may be, extensions of a portion of those already mentioned, and which mesh with the teeth of pinion G. These teeth are suf-.

cient in number, and are so arranged in connection with the stopway l and the teeth and stop-plate g of pinion Gr as to rotate the pinion with the cutter one revolution to sever the band, and then hold the cutter at rest and out of the way during the rest of the process of binding. While the cutter is at restitis made to hold the end of the band. The said movement of the cutter I have shown, and prefer to make, coincident with the first revolution of the twister. At the conclusion of the revolution of said pinions the plates fand g, respectively, engage with the plane surface k and Zupon wheel A, so that said pinions are restrained from revolution until they again engage with the teeth a and c, respectively.

There is also upon the wheel A a second set of lteeth, fm, in the line of the teeth a, and in number sufficient to impart to the pinion F one-half of a revolution, the purpose of thesame being to cause the twister to engage with the wire near the end and carry it vone-half the way round the axis of the twister, so as to be out of the way of the band-wire that is brought down by the binder arm or carrier, whereby the two wires, when being twisted, are disposed upon opposite sides of the aXis of the twister, and in the act of twisting are carried bodily around each other instead of being merely twisted without passing around each other, as might be the case if both were disposed upon the same side of the axis.

In Fig. 1 the parts -are represented in the position occupied when ready to receive a bundle to be bound. The end of the'bandwirea is then, as shown, griped between the cutter E and. the plate e, and the twister has made its half-revolution, carrying the bandwire half-way round the axis of the twister. Ordinarily, 1 prefer to make this half-revolution of the twister just before the other end of the band, having nearly completed the circuit of the bundle, is presented to the twister.

In Fig. 4 the parts are shown in the position occupied when the carrier or binder arm has descended and carried the band wire round the bundle, and the twister is ready to be operated to complete the twist. The succeeding movement is caused by the engagement of the pinion F with the teeth a, which rotates the twister several times around its axis, thereby twisting the wire.

At or about the time the twister commences to rotate the teeth c engage with the pinion G, causing the cutter to make one revolution, whereby the end of the wire is released and the wire again severed, and the new end griped between the cutter E and the plate e, as before. Prior to the releasement of the old end and lthe severing of the new end, as described, the rotation of the twister D has carried each of the ends, respectively, nearly around thev neck of the twister, between it and the loop of the looper H and somewhat underneath the latter, whereby, after being released and severed,'they are held in engagement with the hooks of the twister, while the subsequent revolutions of the latter twist them together.

After the twist has been completed the bundle is liberated, and may be discharged from the machine by any devices suitable to that purpose, as by the rotation of the arms M, that bring up another gavel to be bound.

Having described my invention, whatI claim as new 1s y l. In an automatic binder, a rotating twister and a rotating holder and cutter, having coincident axes, combined with intermittently-rotating operating pinions and a continuouslyrotating actuating-wheel, provided with teeth and stop surfaces or plates attached thereto, whereby the various and complicated functions and intermittent rotations of the twister, holder, and cutter, independently and conjointly, with ,their necessarily varied periods of rest are secured by the simple and continuous rotation of the wheel, as set forth.

2. Arotatingcutter, E, mounted upon a tubular shaft, and provided with an actuating-pinion,G, and arotatin g twister whose shaft has its bearing within said tubular shaft, and is provided with a pinion, F, combined with a wheel, A, adapted to impart to said cutter and twister the intermittent rotations described.

3. The cntterE and twisterD, with their pinions F and G, provided with the plates j' and g, respectively, as set forth, combined with a wheel, A, provided with gear-teeth a and c, and plane surfaces k and l, whereby said cutter and twister are alternately rotated and restrained from rotation, as set forth.

4. The looper H, constructed and operating substantially as described,in combination with the rotating twister D.
