GRAIN-BINDER.

SPECIFICATION forming part of Letters Patent No. 271,074, dated January 23, 1883.

Application filed July 24, 1882. (No model.)

To all whom it may concern:

Be it known that I, EDWARD W. JENKINS, of Chicago, in the county of (look and State of Illinois, have invented certain new and useful Improvements in Grain-Binders, of which the following is a specification.

My invention relates to that class of automatic binders, whether using cord or wire, in which the binding mechanism is tripped or to thrown into action through the instrumentality of the accumulating gavel, so that the sheaves shall be of a practically uniform size.

and density; and it consists in combining with theshipping-lever of the binder clutch a packer 1 arranged to mount by the impact of its teeth upon the accumulating gavel, thereby moving said lever; in combining with the grain-receptacle a rotating toothed packer mounted at the head or throat thereof in such manner as to be allowed a bodily-mounting movemeut,with the impact of its teethupon the accumulating and compressed gavel, and connect-ions between said packer and the shippinglever which controls the binder-clutch to cause the engage- 2 ment or disengagement of said clutch; in combining with the binderclutch and its shipping-lever, and with the grain-receptacle, a rotary toothed packer carried upon one end of a longitudinally movable support, with its teeth projecting into the throatway of said receptacle, and a lever intermediating between the other end of said support and the free end of the shipping-lever, whereby the latter will be operated by the mounting of the packer upon or behind the accumulating gavel; in

combining with a tripping-packer in the throatway of the grain-receptacle a positively-operated compressor or cut-off closing the exit side of said receptacle until started by the tripping 40 of the machine; in an improved clutch consisting of a toothed or ratcheted clutch-half affixed to one of two abutting shafts, and a spring-pressed toothed dog or carrier transversely pivoted to the other, and in the various other combinations and details of construction hereinafter described and claimed.

In the drawings, Figure 1 is a rear sectional elevation of so much of a harvester and binding attachment embodying my invention as is necessary to a complete understanding of the latter. Fig. 2 is an outer or stubble side view, the harvester being omitted; Figs. 3 and 4, side and front elevations of thepacker enlarged; and Figs. 5, 6, 7, and 8, details of the clutch and its shipper enlarged.

A represents the main wheel of the harvester, and B the elevator-frame. A beam, 0, supported by or from the outer elevator-struts, or, if convenient, one of the harvester-sills, carries the receiving side of the binder-f'ame, a portion of which only is shown, the dlscharge side of said frame being borne upon the outside sill of the harvester, or in any suitable manner.

Properly mounted in the binder-frame, be- 6 5 neath the decking or. grain-table, is a constant- Iy-rotating shaft, D, hereinafter called the driving-shaft, driven from the harvester by chain and sprocket wheel or other gearin This driving-shaft, in the present instance, does not pass entirely beneath the binder-frame; but as to its inner, and herein the forward, end terminates about midway of the width thereof, and near said end is provided with a fast clutch-half, d, preferably ratchet-toothed to act in one direction only. It also has near this clutch-half a chain or sprocket wheel, d, by which the packer is driven, as will hereinafter appear. 7

In line with the driving-shaft and abutting against its inner end is the binder-shaft E, by. which the actual binding devices are driven. Keyed or bolted to the abutting-end of this shaft is a tubular head or block, E, which, for the purpose of keeping the two shafts steadily in line at their meeting-point, takes over and serves as a bearing for so much of the inner end of the driving-shaft as projects beyond the clutchhalf. To thisblock, or to cars projecting therefrom, is pivoted by a transverse o pivot a carrier or dog, 6, having a tooth or ,lug, c, projecting toward the toothed face of the driving clutch-half, and urged toward the latter by means of a spring, c seated against a lug upon the block. So long as the carrier. 5 is in engagement with the opposing clutchhalf the binder'shaft will be locked to and revolve with the driving-shaft, thus actuating the binding mechanism; but whenever it is disconnected or thrown out of engagement the binder-shaft and mechanism driven thereby will come to a stop and remain at rest. Such disengagment is caused at the end of each complete revolution of the binder-shaft by means of a switch-lever, F, tulcrnmed atf to a lug or lugs projecting from the tubular casting or su tiporting-bar G, one end of said lever normally resting just over and between the carrier and clutch-half, and having an inclined face,f, which is struck by and forces aside an anti-friction roller, or it may be alug, 6 upon the crown of the carrier as the latter approaches the end of a revolution, thereby swinging said carrier back upon its pivot, away from and out of engagemet with the clutchhalf, and'by the contact between the anti-friction wheel and incline preventing re-engagelnent so long as the lever is undisturbed.

Bolted fast to the beam U is a standard. H, forming part of, or corresponding in outline with, the grain board or ch ute-that is, extending upwardly and bending in to a termination immediately beneath the discharge-point of the elevator. 1n the present instance the body of the standard is formed of two side bars, h, spaced by a block, it, at the head, and by the bolts which hold it to the beam at the foot, so as to afi'ord ledges to said chute and to the inner side of the slotted binding-table I. on either side of the path of the binder-arm, as it moves on its pivot to place the wire or cord around the gavel and -carry it into the bandsecuring devices.

The binding mechanism may be that of the well-known McCormick reciprocating binder, in which case the binder-arm will, enter between the ledges from above; or it may be of some other type, with the binder-arm working upon a stationary pivot, either above or beneath the chute. Thelength and outline of the binding-table will of course depend on the style of said binding mechanism.

K is a rotary fingered wheel, running upon aspindle, is, upon the upper end of a'support, connected by a link, 70 at said end to the standard H, near the head or throatway ot' the chute. The fin gerst' of said wheel are preferably pivoted thereto, and have their heels formed as shoes, which travel upon a cam or eccentric t" arran ed in such manner that the fingers, as they are brought up toward the incoming grain,'assume and are held in a radial position to strike and force it onward,but when at the limit of their effective action are permitted to fold back upon theirpivots, to be readily withdrawn from the stream. The fingers may, however, so far as regards other Ieatures of my invention, be rigid with the wheel, and curved or set back from the direction of rotation, as in certain forms of packers or feeders already well known. The support k, bearing the fingered wheel, packer, or feeder, is pivoted at its lower end to one arm, l, of

nection allowing relative play. To thislast mentioned arm may also be applied an adjustable counterbalancc, Z whereby the sensitiveness of the device may be determined.

A chain, M, runs from the sprocket-wheel d over guide-pulleys at, one of which may be on the pivot-pin connecting the lever-arm Z and support It, and the other mounted in a spur or projection, 70 from the latter, upto and over the sprocket-hub of the packer to drive it.

While a gavel is collecting, exit from the grain-receptacle will be closed by the strand of cord or wire stretched across the passage. way, or by a compressor or stop, which at the proper moment will be withdrawn or swiing away to allow discharge. It is preferable to relieve the band material, so far as possible, of this duty, and therefore, while any form of compressor or stop adapted to co-act with the other instrumentalities of my invention may be employed, if so desired, I propose to mount at a suitable height above the receptacle and near to the head of the chute a rock-shaft, N, carrying pendent tines N, of sufficient length to block the passage of the grain when down. These tines have at first a straight body, a, which brings them near to the packer or feedwhcel, and forms, in connection with the chute, at that point a throatway for the action of said wheel; then they curve or bulgeout. at n to gain space for the gavel and properly shape it. The tines are held closed and swung open at the proper periods by means of a pitman, 0, connecting with a crank, 0, upon the rockshaft, and moved by any suitable part of the a mechanism driven by the binder-shaft, a toggle, 0, being interposed between the end of .said pitma-n and the crank 0, in order to increase the oscillation of the shaft, and consequent throw of the tines to open them rapidly and widely.

In the operation of the machine, the grain accumulating in the receptacle and against the tines or other stop gradually backs up in a more orlesscompactmass againsttherotatingwheel, which, as its fingers meet with increasing resistance, will mount or roll to retain its position upon the crest or rear side of said mass, pulling with it thesupport 7c, and therebyrocking the lever L and depressing the free end of the shipper. This movement of the latter throws its inclined face out of contact with the carrier, which thereupon springs into engagement with the toothed clutch-half on the driving-shaft, and the binder is started, takes the gavel, the tines open for its discharge or re- IOU nioval, bound or unbound, as the case may be, are immediately reclosed, and the fingered wheel returns to its first position, again setting the shipper to meet and disengage the carrier as the binder-shaft completes its revolution.

When the gavel is to be encircled and completely bound within the above-described rereptacle the rotary fingered wheel may serve both as a tripping device and as a packer to consolidate the mass preparatory to binding, and the tines or other stop. as an outside compressor, acting in opposition to the bindinga-rm until the ends of the band are united and the sheaf is ready to be discharged. If, however, a McCormick reciprocating binder is used,

or with some other types which either do not complete or do not commence the binding operation in the receptacle, the otfice of the rotary fingered wheel may be merely to trip the binding mechanism at the proper moment, not notably to pack or compress the gavel for the reception of the band, and the tines will be thrown open as soon as the gavel is grasped for removal.

Should the binder be low level, receiving directly from the harvester-platform without the intervention of an elevator, a spring or equivalent device may be applied to the feedwheel support or to the shipper to reset the tripping mechanism after the discharge of a gavel or sheaf. Such an instrumentality may also be employed where the wheel is to act as a packer to subject the grain to marked compression.

It is obvious that instead of mounting the feed-wheel upon a longitudinally-moving support it may be borne in one arm of a cranked lever; that the form of the clutch may be varied and the shipper and its lever-connections suitably modified to control it; that, according to the nature of the clutch, the binder-shaft may be out of line with the driving-shaft, and that various other'changes in matters of detail or of a subordinate character may be made without departing from the principle of my iiivention.
