10 so that the uppermost one after being loaded with a shock from the harvesting machine, may dump the shock and set the same upright on the ground, in such manner that the lower dumping tray will come uppermost to receive 15 the sheaves which are to form the next shock.

Y One' of the objects of the presentinvention is to provide improved means for holding 'the duplex trays in a horizontal position lrelatively to the frame during the filling operation.

A further object is to furnish a mechanism of this character, comprising novel means for releasing the trays to allow dumping of one tray and the bringing of the other tray into uppermost position.

A further object is to provide Vthe machine frame with rearwardly and upwardly inclined slots to accommodate the tray axle, so that the trays will ride up and over a deposited shock, while the machine is moving forward, without liability of toppling the shock over.

With the foregoing objects outlined and with other objects in view which will appear as the description proceeds, the invention consists in the novel features hereinafter described in detail, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims.

In the drawings,

Fig. 1 is a side elevation of my improved shocker. Y

Fig. 2 is a transverse. vertical sectional view of the same on the line 2 2 of Fig. 1.

w" Fig. 3 is a longitudinal vertical sectional view with the dumping trays in horizontal position. j

Fig. 4 is a similar view but showing the releasing mechanism actuated and the upper- Vmost tray in the process of dumping.

Referring to the drawings, 5 designates a horizontally disposed U-shaped frame consisting of frontcross bars 6 andside bars 7.

Suitable spacing blocks 8 join the side bars to the vertical side walls 9, and between these Y side walls and the side bars, supporting wheels 10 are arranged to rotate on stub axles 11.

Each side wall hasV an upwardly and rearwardly inclined slot 12, in which are journaled the ends of the dumping tray axle 13, 1

and a suitable abutment collar 14`is fixed to each of the end portions of thelaxle to bear against the sides 9 and limit the lengthwise movement of said axle. i The dumping tray assembly consists of a upper tray 15 and a lower tray 16, each having side walls 17 and a rear wall 18, the front of each tray being open when it is uppermost. Y The bottoms of the trays are rigidly connected to the shaft 13 and are spaced apart by blocks 19.

Asbest shown in Figs. 1, 3 and 4, the bottom of each tray projects outwardly beyond the wall 18, and its edge is reinforced by a U- shaped metal strip 20. The rearl end of lthe uppermost tray 15 is prevented from'rising by a gate 21 which extends between the side of the side walls. y

A spring 24 normally holds the gate 21 in contact with the rear ends of the walls 9 to form amovable abutmentV against which the rear end of the uppermost tray bears.`

The front end of the tray assembly is prevented from risingbyfmeans of strap or leaf springs 25. As shown in Fig. 2, there is one of these leaf springs at each side of the machine, and its upper end is hooked over an upper edge of the wall 9, as at 26, and secured to the wall by screws or the-like 27 These springs 25 converge downwardly, buttheir lower ends can move toward the walls 9 when they are forced to do so by either one of the projecting ends of the tray assembly.4

To permit the gate 21 to be opened from 'a remote point,'one edge-of the gate'is provided/,with an `upstanding lever 28 thatis walls 9, and is hinged at 22 to a bar 23which has its ends rigidly connected to the rear ends een connected to a rope 29 leading to the pointl where the operator is located.

In operation, we will assume that the tray assembly is in the position shown in Figs. 1 to 3 inclusive, and that the device is hooked up with a harvester in the known manner. As the device moves forwardly over the field, with the harvester,` the grain lsheaves kwill be deposited in the uppermost tray l5, and when a suflicient numberv ofsheaves has been deposited to form a 'shoclnthe peratorfpulls the rope 29 to open the gate 2l. As this Y releases the rear end of the inoperm'stv tray, the tray assembly willv moveforwardly and downwardly, as shown in 4,'and`vthe shock will be 'deposited on-the ground. Now, asthemachine moves forward, the tray :assembly willofy course be obstructed vby the deposited shock, 'so vvthat the tray assembly tends toswing in a clock-wise` direction to bring'the lowermost tray tothe uppermost position,'1 but in order to prevent the shock from being'knoeked over, the axle 13 will ride upI the slots l2, whereby the tray assem- @'25 vblywi-llrise'and clear the depositedV shock,

l,and at the sametime, therear edge of the tray which wasmoriginally uppermost, will havev its ends come' in contact with the leaf springs 25, so as to compress the latter and '30 force them towards the walls 9, until 'the tray end passes'beneath the lower edges ofi-the springs 425. In the meantime, the operator `will, have released the` cord 29, Eand tliegate 2 1l will be in the positionY shown in'Fig. 3, Vwith thefresult that the projecting end 2O of the tray, which was originally lowermost, will come in'contact with the lower edge of -the gate and be halted thereby. The original l'owermo'st tray is now inthe properposition toreoeive the sheaves toform'the next shock.

Thebvariousgparts of the device may be 'inade of any suitable'materiahbut Irpref'ertogmake the tray assembly of sheet metal.

Y Y rom they foregoing it is believedthat the construction, operation and advantages of the invention maybe .readily understood,A and I am aware that changes may be made `in they ldetailsdisclosed, without departingfrom the spirit of the invention, as expressed in the olaims. w, a A, ,y VVhatI claim and desire ters 'Pat'ntis: t H
