scoor-nonnn.

To all whom it may concern:

Be it known that I, TVILLIAu J. Clones, a citizen of the United States, and a resident of Otterbein, in the countyofBenton and State of Indiana, have invented certain new and useful Improvements in Scoop-Boards, of which the following is a specification.

My invention is an improvement in scoop boards, and has for its object to provide a board of the character specified, especially adapted for use with wagons having flaring sides, and used for hauling grain, coal and granular matter, wherein the board provides an end gate under normal conditions, capable of being entirely detached from the bed, and which may be lowered into inclined orapproximately horizontal osition to serve as a scoop board, and wherein the pressure upon the board or gate may be first relieved before the board or gate is open and into position to be used as a scoop board.

In the drawings:

Figure l is a rear view of a wagon provided with the improved scoop board showing the board closed,

Fig. 2 is a top plan view of Fig. 1,

Fig. 3 is a section on the line 33 of Fi 1,

Fig. 4: is a perspective view of one end of the angle bar.

. In the present embodiment of the invention, the improved bed comprises a bottom 1 and side walls 2, which have outwardly offset portions 3 at their upper ends, connected to the body portions 2 by inclined portions 4, the portions 2, 8 and 4 of the walls forming a flaring bed. The usual cross bars 5, one of which is shown, are arranged transversely of the bottom, beneath the same, and the ends of this bar in the present instance are supported by rods 6 connected with the inclined portions 4 and passing through the ends of the bar, and engaged by nuts above and below the bar.

Straps 7 are secured to the outer faces of the sides, and the lower ends of these straps have threaded stems which pass through the cross bar 5 and are engaged by nuts below the bar. Plates 8 of wood are arranged at each side of the body, fitting against the inner face of the portions 2 and extending to the top of the side walls of the bed, but spaced inwardly from the outwardly ofi'set portions 3. The scoop board proper is arranged between these bars, the said scoop Specification of Letters Patent.

Application filed March 17, 1920. Serial No. 366,473.

board being in the form of a leaf 10 which is hinged at, its upper end to swing outwardly.

This leaf carries at its upper end an angle plate 11 which is secured thereto transversely of the leaf and at each end the angle plate is provided with a threaded stem 12. The body of the angle plate is of the same length as the width of the leaf, so that the stems 12 extend beyond the ends of the leaf.

The plates 8 have notches 13 near their tops in which the stems 12 are received, and latch plates 14 are pivoted to the tops of the plates 8, and swing down over the notches to prevent rearward movement of the stems. These plates 14 have finger-pieces, as shown for convenience in manipulating the plates, and when they are down in the position shown in Fig. 3, the angle plate and the top of the leaf are prevented from outward movement.

Nuts or internally threaded sockets 15 are journaled in the portions 3 of the sides, in alinement with the stems 12 when the scoop board or gate is closed, and these sockets are also movable longitudinally in the portions 3 of the side.

Referring to Fig. 1, it will be seen that each socket has at its outer end a crank, and near its inner end a collar 16, and the movement of the socket is limited by the crank and collar in outward and inward movement. These sockets are designed to engage the stems 12, to firmly lock the upper end of the leaf 10 in place.

At its lower end the leaf 10 is prevented from outward swinging movement under normal conditions by latch levers 17. These levers are pivoted at 18 to the plates 8, and they engage keepers 19 on the leaf 10. These keepers hold the latch levers 17 in approximately horizontal position, when the levers are engaged with the keepers.

An angle plate 20 is secured transversely of the bottom of the leaf 10 near its bottom, and this angle plate extends at its ends across the keepers. When the latches are swung upwardly at their lower ends, the lower end of the leaf 10 is released, and it may swing outward, to relieve the pressure within the bed, swinging on the stems 12 as pivots.

The scoop board is supported in horizontal position, by means of supporting arms, one of which is arranged at each side of the ping upon the bottom of the bed, to prevent spaced above the bottom of. the leaf 10,a

distance such that when the upper end of theleaf swings outwardly, it will engage the end of the bottom 10f the wagon bed,

to prevent inward sliding movement of the leaf, and will leave enough of the leaf lapdislodgment of this end of the leaf.

The operation of the improved board is as follows: With the parts in the position of Fig. 3, and with the latch plate let at the left swung downward, when it is desired to relieve the pressure in the bed, the latch levers 17 are lifted. The pressure of the grain or other material in the bed forces out the lower end of the leaf, and the pressure is relieved. Now the leaf 10 is closed and locked in position by the latch levers, the

' latch plates 14: are released, and the sockets 15 are turned until they are out of engagement'with the stem 12., The upper end of the leaf now swings outwardly and downwardly into the broken line'position of Fig. 4, the inner end of the board being supported bythe body 1, and theouter end by the sectional arms 22-23.

The angle plate 20 serves as a stop for engaging the end of the bottom 1, to limit the inward movement of the scoop board. The plates 8 are fixed, being secured to the portions 2 of the side walls of the bed at their lower' end, and being held at their upper ends by braces 27 which are connected with the flaring portion 3 of the'side wall, and which extend inwardly to the plates.

Referring to Fig. 2, it will be seen that the leaf 10 is reinforced by a vertical bar 10 which provides side flanges for the scoop board when open, and which abut the inner faces of the plates 8 when the board is closed.- Strips 28 of metal are secured to the plates 8 on their inner faces, and these strips extend over the edges of the bars 10 when the scoop board is closed, to prevent small grain working out the sides of the scoop board.

I claim 1 1. In combination with abed having flaring side walls, of a scoop board for closing the rear thereof, platessecured in vertical position at the rear end of the body, the scoop board being arranged between the plates, said board having'atoits top a transverse bar provided at each end with a threaded stem, the plates having notches forpermitting the passage of the stems, and having latch plates for preventing disengagement of the stems, sockets having cranks journaled in'the sides of the bed and movable longitudinally toward and from the stem'and internally threaded to engage the stems, latches pivoted to the plates at each side of the lower end of'the scoop board, the board having keepers for engagement by the latches, and folding arms arranged between the threaded stems and the platefor supporting said scoop board in horizontal position, said board havinga stop for engaging the end of the bed when it is lowered to limit the inwa'rdmovement of the board. f r i 2. In combination with a wagon'b'ed, of a supporting plate arranged at each side of the rear thereof, a scoop board between the plates, releasable means'at the lower end of the board and supported by the board and plates for preventing outward movement of the bottom of the board, said board having at its upper end a transverse bar provided at each end with a stem, the plates having notches for preventingdisengagement of the stems, supporting arms arranged between the "plates and the stems, and sockets journaled in the sides of the bed and movable toward and from the stems, said stems and sockets being threaded to engage each other. 7
