`i-mRvEsTER-RAKE.

SPECIFICATION forming part of Letters Patent No. 278,850, dated June 5, 1883,

Application filed November 7, 1882.

To @ZZ whom t may concern:

Be it known that I, SAMUEL D. BATES, a citizen of the United States, residing at Lewisburg, in the county of Union and State of Pennsylvania, have invented certain new and useful Improvements in Harvester-Rakes, of which the following is a specification, reference being had therein to the accompanying drawings.

Figure l is an elevation of the raking mechanism from the grain side of the machine, partly insection, on line y QI/,Figfh Fig. 2 is a sectional view, showing the devices for tripping the switchof the rake-arms. Fig. 3 is a plan view of the cam-track. Fig. 4 is a top view of the raking mechanism and a portion of the rest of the machine. frontview, partly in section, on line x af, Fig. 4. Fig. 6 is aperspective of the tripping mechanism.

In the drawings I have shown sufficient part of a harvesting-machine to illustrate the methed of applying my improved raking and reeling mechanism, though it will be readily understood that the latter can be employed with machines more or less differing from what is shown. The power is transmitted from the drive wheel by any suitable train of gearing. I prefer that shown in another application heretofore filed, of which this is a division.

The raking mechanism is supported in a tubular standard, L, fastened to the platform. In this standard is journaled a vertical shaft, carrying at the upper end arake-head, M, and. at or near its lower end a bevel-wheel, M.

The rake-arms N are respectively hinged to the rotating head M. Said rake-arms may be of the kind shown in previous Patent No.

236,533, or of any preferred character. Each arm has on its hinge a downwardly-projecting stud, m, and roller m. Gamways for raising and lowering the rake-arms are supported upon the stationary tubular standard L, said camways being substantially of the character shown and described in my aforesaid patent. The camway which serves to guide the .arms whenthey are to operate as rakes to sweep the grain from the platform consists of an upper part, O, describing an arc of a circle, and a lower part, O2. Theway which serves to guide Fig. 5 'is a` (No model.)

the arms when they operate as reels consists of the part O, the pivoted cam or track O, a switch or cam-gate, P P2, and ashort stationary cam, P, situated between the pivoted can. O and the switch P P2. The switch P P2 is formed in the shape of abellcrank lever, with the pivot p on its underside mounted within a tubular bearing depending from the camway-support.- The pivot o of the cam or track O is mountedin a tubular bearing, 0. The pivot p of the switch P P2 carries 'an eye, p, secured directly to the pivot p or to a plate or arm, p`, attached to said pivot. p is a coiled spring, one end of which is connected to the pivot p, the other end being attached to some stationary part. This spring p tends to force the forward arm, P, of the switch outwardly, and when said arm is at its outermost position the inner or rear arm, P2, is situated across the inner camway. If one ofthe arms n operates as a rake-that -is to say, moves so as to carry its roller m along the camway 0"-it will strike against the rear arm, P2, as it moves rearwardly, and will throw said arm P2 outwardly, thereby bringing inward the arm P, so as to close said camway O?. As soon as the arm P reaches its innermost position it is locked there by means of a link, Q, pivoted to the arm pl by a pin, q, and provided with a shoulder, s', which engages with a stationary shoulder, o', after the switcharm has been thrown in. This shoulder r is upon a stationary bracket or pendant secured to the under side of the cam-support and consisting of a vertical grooved part, R, and a horizontal part, It', for fastening-it in place. The vertical part' R is provided with a longitudinal way or passage. sage there is placed the sliding tripper R2. This tripper is provided with a series of teeth, 1", upon the rear side, and aseries of teeth, '13,. upon the front side.

S is a lever, pivoted at s in the lower end ot' the vertical part R ofthe bracket. The outer or rear end, s2, of the lever is so situated that it can engage with cams S upon the upper side ofthe bevel-wheel M', which cams successively throw the end ofthe lever up, it falling again after the cam passes from under the outer end. S2 is a dog, pivoted to the lever S and arranged to engage with the teeth r on the tripper R2.

In this way or pas- IOO 2 evaso Then a cam, S, lifts up the lever S the dog S`l engages with one of the teeth a-nd thrusts the tripper R2 up one step. After being thus lifted one step it is held by means of a springcatch, T, which is provided with a dog, z, that engages successively with the teeth r2 on the front side of the tripper R2. The dog is forced inwardly by means of a coiled spring, z", at the lower end of the catch.

There is an aperture at '1 '1 through the bracket, and thelink Q passes through this aperture. W'hen the arm P of the switch is in its outmost position the link Q has its end thrust forward far enough to engage with the upper end of the spring-catch T and force it forward, so as to hold the dog t out of engagement with the teeth Ir`.

The operation of these parts last described is as follows: If it bc desired to have every fourth rake-arm operate as a rake, the tripper R2 is so adjusted that at the fourth upward movement of the lever S and dog S" the tripper shall lift the end of link Q to release the shoulder s from the shoulder r. If, after the tripper is so adjusted, the machine be put into operation, it will be seen that as the wheel H revolves, one ofthe cam S willlift up the lever S, which, by its dog S2, will lift up the tripper one step. Assoon as the cam S passes from the end of the lever Sthe latter drops, carrying the dog S2 Y away from the teeth 1",- but the tripper is prevented from falling by the dog t on the spring-catch T. The outer camtrack still remains open, and the next rakearm will be thrown up away from the platform. \Yhen the second cam S strikes the lever S the tripper is lifted another step and is held there by the spring-catch, the switch still remainingunaffected. The third cam S operates in a similar manner to lift the tripper R2. When the fourth cam engages with the lever to elevate the tripper the fourth step it (the tripper) has reached a point high enough to engage with the link Q, and it releases .the shoulder s from the shoulder r, whereupon the spring p throws the switch arm P outward and pushes the link Qthrough the aperture r* far enough to thrust the spring-catch T outward. The thrusting of the spring-catch outward drops the tripper to its lowermost position, after which it is ready for a similar series of operations. After t-he switch-arm I is moved outward by the spring the inner camtrack is opened and the fourth reel-arm is carried down over the platform, but as soon as its roller ill strikes the arm I"l ofthe switch it will swing the arm P inward again, and thereby draw the link Q back away from the springcatch T far enough to have the shoulder s again engage with thc shoulder r, after which the device is set for another operation. i

If it be desired to cause the raking of the platform at shorter intervals, this can be aceomplished by preventing the tripper RL from falling to its lowest position. Preferably a series of apertures, r9, are formed in the bracket R, through which apertures a pin, 1:, can be passed and secured in the vertical -path of the tripper, so as to stop the latter. The positions of these apertures are so related to the positions of the teeth r on the tripper that when the pin r is in the third aperture from the top, three of the step-by-step movements will move the tripper high enough to release the switch; when the pin is in the fourth hole, four of such movements will release it, and so on throughout the series in an obvious manner.

It' the operator should at any time desire to delay the raking action, he can accomplishthis by releasing the tripper-R2 before it reaches the link Q in its upward movement. One of the forms of mechanism whereby the operator can thus release the tripper I have shown in the drawings, it being constructed as follows:

U represents a rock-shaft mounted in bearings on the draft-frame. a foot-crank, U, in front of the operatonsseat, and a crank-arm, fu, at the inner end.

V is a swinging lever, pivoted at its upper end to the bracket R or to the cam-support, and at its lower end pivoted to a link, V, which in turn is pivoted to the crank-arm lu.

rr is a laterally-projecting pin carried by the swinging lever andarrangedto press against the lower end of the spring-catchT when thclower end of the lever V is moved backward. The lower end of said lever is thus moved backward by the operator by pressing his foot upon the crank I. The pin r swings the upper end of the catch T ont far enough to rclease the dog t from the teeth Ir`` of the tripper. In this way the operator, while in his seat, can regulate with ease the size of the bundles which are to be delivered from the platform.

The swinging lever V is held in the proper position relatively to the spring-catch T by means of two coiled springs, YL Y, carried by aloosely-mounted arm, Y", said springs engaging with the opposite sides of an arm, V, formed with or attached to the lever Y.

W'ith a mechanism of this sort I obviate entirely the necessity of the complicated devices which have heretofore been used for Vlregulating the raking of the platform, and provide a simple means for varying the interval between the successive operations of raking.

Heretofore it has been necessary to remove one or more parts and replace them by others in order to effect a variation in this respect. By having a rising and falling tripper the fall of which can be regulated by a pin or equivalent mcans, I provide a much simpler and more accurate and durable mechanism than those heretofore used with which I am acquainted.

By means of the following devices the opera- .tor can cause the raking ofthe platform at any timethat is, by means of the next cam S.

Y* is an arm pivoted to the link Q and hanging downward. Its lower end is adapted to be swung forward, so as to rest upon the surface s, formed inthe dog S2. This armV8 can It is provided with n IOO IIO

be thus swung forward by the operator by means of the rock-shaft U, treadle U, link 'V and lever V, arm V, and the part S5, proj ecting laterally from the arm Tf'. rlhe proper movement is effected by turning the foot-crank U forward, which results in having the part S5 moved forward, and it swings forward the arm VS until its lower end rests upon the aforesaid surface s on dog S2. After the arm V8 is engaged with the dog'St it will be seen that a single rising of the lever S will throw up .the link Q far enough to disengage its shoulder s from shoulder r, and thus open the switch.

I am aware that switch-trippers have been heretofore used adapted to unlock a shouldered latch, and in combination therewith means for imparting a step-by-step movement in circular paths to means for operating the trip, andl do not claim such devicesas my invention, but there are many advantages incident to a construction ofthe character of mine which are not to those which have been heretofore used. By employing a rectilineally-moving trip mounted loosely in a guide l avoid the necessity of springs and the other returning devices that have been heretofore used, which are liable to get out of working order, and can be repaired only with serious difficulty and inconvenience. ln my case, the tripper being loosely mounted and allowed to return by its own gravity, it need not be permanently connected with ,the other parts, and no serious disarranging of it or stopping of its operations is possible under ordinary circumstances. In all the. ordinary positions of the machine it will operate with uniformity to a greater extent than is the case with those in which the trip is carried by the swinging arm or is arranged to oscillate about an axial line.
