GRAIN-BINDER.

rEPIiGIE'ICATION forming part of Letters Patent No. 343,152, dated June 1, 1886.

Application filed February 24, 1885. Serial No. 156,859. (No model.)

In a number of binders constructed by the Mc-- Connick Harvesting Machine Company during the last season a peculiar form of table-trip, so called, was employed as auxiliary to the outside tripping and compressing fingers, consisting in a longitudinally-slotted metallic arm hinged at the inner side of the bindingreceptacle, beneath the decking, and rising through the usual slot provided therein for the play of binder-arm, which slot, of course, was widened, as in the new arrangement the binder-arm played between the lateral bars of the table-trip, and of such length that its outer end reached and vibrated between said compressing-fingers according as it happened to be actuated. In its construction at that time this table-trip was closed at its outer endthat is to say, the two side arms of which it was composed curved and met integrally at that point. This was objectionable, as straws would frequently be carried by the binderarm against the closed end of the trip and impede its movement up or down, so that it would either fail to yield for one gavel or else to return to position for the next, in which latter case the binder would continue to operate incessantly. The table-trip rested upon and was supported in an elevated position by an arm from a tripping rockshaft connected by another arm with the outside trip-fingers, so that by the movement of either or both tripping devices against its respective arm from the rock-shaft said rook-shaft would be oscillated and the binding mechanism set in motion. The trip-fingers, also, instead of being hinged at the end of a long supporting-bar pivoted to the heel of the binder-arm, as in the type of machines at present most generally used, were adjustably secured to a block loosely journaled on a supporting rock-shaft, and alongside this block was placed a crank keyed to said rock-shaft and having a lateral lug taking into an elongated slot in the side of said supportingblock, so that as the fingers rocked outward they might, by bringing one end of the slot against the finger, eventually force back said crank and rock the shaft to start the binder, while at the same time they had a free range of movement sufficient to allow for the accumulation of the gavel before such starting. In this latter arrangement also there was danger of the slot becoming clogged, and thus interfering with the perfect action of the outside trip. These features have been made the subject of an application filed by Villiam It. Baker jointly with myself on the 29th day of September, 1884, No. 144,247, and need not be further explained herein.

My present invention relates to the two instrumentalities above adverted to, and is as follows:

First. It has been found, as already intimated, that the uniting of the side bars of the table-trip at the outer end is objectionable, since the binder-arm, playing up and down between the bars, frequently packs grain into the slot at said end, where it lodges and accumulates in such manner as to clog the play of the trip upon its pivot and make it uncertain. Therefore I leave the bars open or disconnected at this end, carrying the slot clear through, so that any grain coming between them and pushed onward by the binder-arm may pass out without obstruction, and, to prevent their being wedged apart, I connect or brace them by an under-curved bridge somewhat preceding this end, and dependingso far beneath them that it will not interfere with the passage of grain.

Second. The segmental slot in the side of the block which supports the tripping-fingers also has proven to afford a lodging place fordust, chaff, and broken straw which lodge therein, owing to the play of the finger from the adjacent crank -.arm, and accumulate until this play is so seriously hindered or limited as to affect the size of the bundles. For this reason I propose to .open an ineffective sideof this slot near the exterior of the block, so that any accumulations of this sort may drop out,

IOO

a spring between the heel of their supportingblock and the outer end of the crank-arm from the rock-shaft on which they play, and I further propose to make this spring adjustable, to control the facility with which they yield. This, it will be understood, is independent of or supplementary to the spring heretofore used between the tripshaft and the lockingdo.

Fourth. hen the arms from the trip-shaft, acting, respectively, with the table-trip and with the outside trippingfingers, are both integral and permanently applied to the trip shaft, so that one cannot be removed without the other, the tripping will oftentimes be too delicate, at least in heavy or wet grain, so that the bundles are made too quickly and too small. To obviate this, I make these arms in dependent each of each, and secure them independently to the shaft, so that one or the other may be removed to permit the action of but a single one of the tripping instrumentalities where the state of the crop is such as to make this advisable.

In the drawings, Figures 1 and 2 are respectively plan and side elevations of my improved table-trip; Figs. 3 and 4, respectively, plan and side elevations of my independent trippingarms from the trip-shaft; Fig. 5, a plan of the supporting-block for the outside compressing and tripping fingers; Fig. 6, a like plan with said fingers in position; Fig. 7, a side elevation of the supportingblock, and Fig. 8 a plan of the crank-arm sleeved to the rock-shaft upon which said block is mounted; Fig. 9, an elevation from the inner side of the supporting-block, crank, and tripping-fingers in position, and Fig. 10a side elevation of the just-mentioned parts in the same arrangement; and Figs. 11 and 12, respectively, plan and side elevations of the foregoing parts arranged in their relative positions for conjoint operation.

' A is a metallic table-trip, hinged, as in the machine described in the above-mentioned application, at the point a, to the upper supporting-bar, a, of the binder-frame, and serving also, as therein, the purpose of an under compressor. This table-trip is formed of two bars united at the hinged end by a connecting-sleeve, a", integral with each. From this they extend parallel with each other at such distance apart as to leave a broad slot, a, for a length sufiicient to accommodate the play of the binder-arm, which, in machines of this construction, generally rises from beneath. Near their ends they converge slightly, and then again become parallel, leaving a somewhat narrower slot, a, in continuation of the first, which extends through to the air. This convergence is simply to bring them sufliciently near together to pass between the checks of the outside tripping and compress ing fingers, and if such fingers should be placed farther apart than usualthe convergence will not be found necessary. Just at the point where they begin to converge they are connected by a subtending bridge, a which curves or bellies down, as shown, suflicientl y to escape entanglement with the grain passing along said trip. A trip arm or lever, B, branching from the trip-shaft B, comes in contact with a ledge on one bar of the table-trip and sustains it normally in its highest position. Therefore it follows that whenever the'tabletrip is depressed by the accumulation of grain thereon this trip-arm is also depressed at its contiguous end, and serves as a lever to rock the trip-shaft. In the former application the arm was represented as integral with or arranged in fixed relation to a second triparm, B, also diverging from the trip-shaft, but operated by the outside trippingfingers, as will presently appear, so that both permanently worked together, and neither could be removed without the other. This arrangemerit, as already explained, has proven to fall short of perfect efficiency under all circumstances. I therefore form each trippingarin independently, and provide each with a hub, b, in the present instance squared to slip over a square portion of the trip-shaft, and provide such hub with a set-screw, b, whereby it may be clamped in fixed position on said shaft, ormay be loosened and slipped laterally to leave either of the tripping devices at rest, in order that the full effect of the accumulating grain may come on a single instrumentality.

Instead of being square, the trip-shaft may of course be provided with a spline or feather, and the sleeve or hub on the trip-arm with a corresponding groove, the set-screws of course still being used to hold them in adjusted position.

The outside tripping and compressing fingers, G, are mounted, as before, upon a block, 0, having an arched crown with longitudinal and transverse slots, said crown fitting the curved face of the fingers, and the transverse slots receiving a tongue from said base, and a clampingbolt, 0, passes from the base through the longitudinal slot, so that by loosening the bolt the fingers may be adjusted in and out along the block, to diminish or increase the graina'eceiving space and the consequent size of the gavel. This block is journaled loosely upon the rock-shaft D, which, at its front end, is connected by a crank and pitman with a lever operated by a cam-track in the usual gear and cam wheel, so as to be restored to position after each binding operation has been concluded and the sheaf discharged.

As explained in the previous application, already referred to, the just-mentioned supporting-block has an inwardly-projecting lug or toe, d, which comes beneath the corresponding triparin, so as to raise it and rock the trip-shaft whenever, the tripping-fingers are pressed sufliciently back, and which, by means of said arm and the spring between the tripshaft and locking-dog usual in this type of machines, aids in carrying the trippingfingers back to position whenever they have from any cause receded therefrom. Alongside the block a crank-arm, E, is keyed to the supporting rock-shaft, so as to come in close proximity to one face thereof and move therewith, or itself move the shaft. Formerly this arm had a loose connection with the block by means of a lateral projection taking into a curved slot in the adjacent face of the block, or vice versa; but this slot being closed at each end was liable to be obstructed by chaff and broken straw. Therefore I now form it as a notch, 6, open to the air at the heel of the block, and discharging freely whatever debris momentarily eni ers it. WVith this expedient the lateral finger may be supplanted by the lateral sleeve from the crank, which sleeve serves as means for connection with the hinged leaf or tail-board at the foot of the bindingreceptacle, so as to open this leaf whenever the rock-shaft D is oscillated; or, instead of the slot or notch, or sup plemental to it, the heel of the block may have laterally-projecting lugs 6, one at top and one at bottom of the slot; or, in other words, at each extreme of the permitted movement between the block and the crank,.which lugs in turn come against the adjacent edges of the crank.

To entirely obviate any possibility of dog ging, I deem it preferable that both lugs and notch should be used concurrently.

The construction just described facilitates still another improvement, which, however, is not necessarily dependent upon these specific features, although practically beneficial therewith, and that is the application of a spring independent of the spring formerly used and above alluded to, whereby the tripping-fingers may be returned to position after depression. For this purpose the heel of the block which supports the fingers has, above the slot or lugs which limit its play, an offsetting lip, f, suitably formed on its under side, to serve as a seat for a spiral spring, F, while the sleeves at the end of the crank over the supporting rock-shaft have an opposing lip, f, similarly formed to receive the other end of the spring, whereby, whenever the fingers are rocked back upon the supportingshaft under the pressure of the accumulating grain they will gradually compress said spring until they reach the point at which the bind ing mechanism is started or their supportingblock engages with the crank-arm on said shaft. They will therefore oppose an elastic resistance to the grain, and, after the binding operation, will he certainly restored to their normal position.

In order to adjust the stress of the spring, I prefer, instead of resting it nakedly upon the upper (or lower) lip, to interpose a disk, f having a seat for the adjacent end of the spring, and receiving one end of a set-screw, f, threaded into said lip, whereby the normal space between its seats may be increased or diminished. Instead of said set-screw the disk may have a screw-shank fitting into the lip, so as to be adjusted therein. This spring, in

addition to its office in returning the trippingfingers to place, has a further function in assisting the discharge of the bundle, since while this bundle is being discharged by the usual revolving ejecting-arms, the trippingfingers are necessarily depressed below the horizontal; but their spring is continually urging them upward against the bundle or sheaf, so that as it reaches their ends they fly up, giving to it a final push from the machine.

It will be understood that although my above-described improvements all relate to a single machine, and to a single object, and will, so far as I am at present aware, be used conjointly, some features of the invention are capable of separate use in connection with mechanism of different structure, but still performing the same function or accomplishing the same effects relatively to these as their cooperating parts herein described.
