SHOVELlNG-BOARD FOR VEHICLES. c

SPECIFICATION forming part ofA Letters Patent No. 712,328, dated october 28, 1902.

Application led April 14, 1902. Serial No. 102,944. (No model.)

To all whom t may concern.:

Beit known that we, JAMES A. PAXTON, residing at Ellsworth, and JOHN G. PAXTON, residing at Colfax, in the county of McLean and State of Illinois, citizens of the United States, have invented certain new and useful Improvements in Shoveling-Boards for Vehicles gand we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the a'rt to which it appertains to make and use the same.

Our invention relatesY to improvements in shoveling-boards for vehicles.

The object of our invention is to provide a shoveling-board which will be easy to manipulate and effective in operation.

It consists of guides fixed to the side pieces of the said board and means carried at the end of said guides for locking the board in a closed or upright position.

It also consists in certain other novel constructions, as will be hereinafter described and claimed.

In the drawings, Figure l is a fragmentary perspective view of the back end of a wagon, showing our improved shoveling-board applied thereto. Fig. 2 is an enlarged sectional view through a portion of the saine, parts being broken'away to more clearly show the form of the guide. Fig. 3 is a detail view of the lock. Fig. 4is a section through the same. Fig. 5 is a section through the guide and its engaging pin.

Like numerals of reference indicate like parts throughout the several views.

Referring to the, drawings, the numeral l represents the bed of a wagon, 2 the sides, and 3 our improved shoveling-board. The said board may be of any desired size; but we preferably give it such proportions as will fit the' back end of the wagon, as shown, the

height being equal to the height of the sideboards 2 and the length great enough to extend beyond the said side-boards and reachl to the outer face of a strengthening-strip 3a, which is secured to the end of the said board. Fitted around each end of the said board and screwed or otherwise securely fastened thereto are the side pieces or plates, as 4. We preferably construct these side pieces of sheet metal, although of course any suitable material may be'used for this purpose. As each device, as 13.

end of the base-plate 3 is provided with the same construction of side pieces and guides,-

it is only7 necessary to describe in detail one of said ends with its coworking parts. In order that this board might move on the desired arc, with its pivot-joint at the upper edge of the bed l, as at 3', and to hold vthe said board against displacement, we provide on the inner face of the side plates the metallic segmental guide 5. This guide is so shaped and positioned that when the said' board is lowered to a horizontal position the inner edge 6 thereof will be caused to rise a triiie above the upper surface of the bed l, so as to permit an unobstructed thrust of the shovel over the joint between the two parts-that is to say, the path of the guide is not an arc of a perfect circle, but that end which engages the guidepin 7 at thetime when the board is in alowered or horizontal position is in operation about one-fourth of an inch nearer the point 6 than the opposite end thereof, the said diversion from the line of the perfect circle being greatest at a point marked 8 and gradually decreasing until it meetsthe said circle, as at 9. It is obvious that in order for the said guide-pin 7 which is stationary, to continue its travel in the groove 10 of the guide 5 it is necessary for the said end 8 to be raised a distance equal to the diversion of the said guide from the said perfect circle, and in so doing, the guide being riveted or otherwise securely fastened to the side plate 4 of the base-plate 3, the said board will be caused to rise a distance equal to the variation of the aforesaid parts. To clearly show this difference we have shown in Fig; 2 of the'drawings a dotted line l1, which is an extension of the true circle struck from pivot-pointl 3. Any suitable brace or braces, as l2, may be employed to more securely attach the end 8 to the extended lower corner of the side plates 4.

In order to secure our board against accidental displacement after it has been raised to a horizontal position, we provide at the opposite end of the guide 5 a suitable locking This locking device is circular Vin form and has a slot, as 14, extending from its outer periphery to the center thereof and in such a position as that when the handlel is turned to its highest point the said'slot will register with the path of the guide. Thus it will be seen that when the board 3 is turned IOO to a perpendicular position the pin 7 will slide directly into the slot 14, whereupon it will only be necessary to turn down the handle 15, bringing the solid wall 16 across the path and effectually preventing the falling of the board. In order to give this locking member the proper throw-that is to say, to bring the slot 14 in proper alinement with the path of the guide-we provide upon the outer face of the said member and around the hub of the handle a cut-out portion, as 17, which forms the abutments 1S and 19, the former of which stops the upward movement of the handle 15 when the slot 14 is in register with the path of the guide and thelatter arrests the downward movement of the said handle, presenting the solid wall16, as before mentioned. These shoulders 18 and 19 abut against the lug 19 formed integral with the guides. These locking members and guides are preferably of malleable iron and may be secured in any suitable manner to the side plates 4. An aperture to receiveitis formed in the said side plates and the whole mounted within the enlarged portion 2O of the guides.

It will be observed from the drawings that the guide-pin 7 is placed at the strongest point possible--that is, through the side plates and cleats which are placed to receive the ordinary gate 21. This pin is in the form of an ordinary bolt passing through the two members above mentioned and also through a separate plate 23, placed on the outside of the said side plates 2. An antifriction roller or washer 24 is provided between the head of said bolt and the outer face of the plate 23 and forms an enlarged head to travel in the path 10. It will be noted that we employT no hinges whatsoever aside from the guides, the pin sliding in the said guides forming all the pivot necessary.

In order to facilitate the easy removal of our board from engagement with the pin 7,we provide near the end 8 a suitable recess or brokenout portion, as 25, through which the said pin and roller may be slipped. A bridge, as 26, spans the said opening and forms a rigid connection between the parts.

Although we have set forth one particular embodiment of the presentimprovement, yet we do not desire to limit ourselves to the exact construction herein shown and described, but shall feel at liberty to deviate therefrom to any degree within the spirit and scope of our invention.

Any suitable means might be employed to retain the locking memberin position, but we preferably employ the following: The aperture formed in the guide 5 to receive the locking member is formed with a bushing, as 5', to engage the space between the

flanges

5 and 5* of the said locking member, and a countersink 5c is formed to receive one ofsaid Iianges.
