ADJUSTABLE WAGON BOX BRAfIE Walter H. Dohrman, Emerson, Nebr.
Application November 23, 1954, Serial No. 470,763
2 Claims. (Cl. 296--) The present invention relates to side braces for the walls of a grain wagon.
The principal object of the present invention is to provide a brace for the side walls of a grain wagon and one that is adjustable to permit the side walls to be returned to a vertical position after they have been deformed outwardly by the weight and bulk of grain carried by the wagon.
Another object of the present invention is to provide a brace for the side walls of a grain wagon box to permit the side walls to be readjusted to a vertical position after they have been deformed by the bulk and weight of grain carried in the box and after the ends or side edges of the platform have been deformed downwardly due to the bending movement of the side walls.
A further object of the present invention is to provide an adjustable side brace for the side walls of a grain wagon box of inexpensive construction and one which is easy to attach to existing grain wagon boxes as an extra brace or to replace the braces attached to the side walls.
These and other objects of the present invention will be fully apparent from the following description when taken in conjunction with the annexed drawings, in which:
Figure 1 is a side view partly in cross section of the brace of the present invention :as attached to the side wall and platform of a grain wagon box;
Figure 2 is a front view in elevation of the present invention; and
Figure 3 is a vertical view in cross section on line 33 of Figure 2.
Referring in greater detail to the drawing in which like numerals indicate like parts throughout the several views, the invention is seen to consist of a brace 10 secured in an upstanding abutting position to the side wall 11 of a grain wagon box or any other box on a vehicle which carries bulky and heavy loads.
Bolts or rivets 12 secure the brace 10 to the side wall 11 with the lower end 13 of the side wall resting upon a channel iron strip 14 on the outer side edge of a platform 15.
The brace 10 is of L-shaped construction with one leg in abutting face to face relation with the side wall 11 and with the other leg projecting perpendicularly to the side wall 11 and tapering from its lower end 16 to its upper end 17.
A foot plate 18 is welded or otherwise secured to the lower end 16 of the brace 10 and is provided with a hole Patented Nov. 20, 1956 means of a nut 21 which is in threaded engagement with the bolt below the strip 14.
The foot plate 18 is also provided with another hole 22 to receive one end of the bolt 23 which has its head 24 in abutting relation with the strip 14 on the platform 15.
The hole 22 is preferably threaded, although not necessarily so, as the nut 25 forms a support for the foot plate 18.
As seen in dotted lines in Figure 1 at 26 the side wall may be swung at its upper end inwardly with respect to the platform to correct any outward bending due to the bulk or weight of the grain or other material carried in the wagon box. The vertically extending bolt 23 may be turned or the nut 25 adjusted upwardly or downwardly to effect this swinging movement.
The bolt 20 forms a fastening element securing the brace to the platform and adjustment of the nut 21 may be necessary to permit the swinging movement of the upper end 26 of the side wall 11.
While a single embodiment of the present invention has been here illustrated and described, it is believed that other embodiments may be made and practiced within the scope of the appended claims without departing from the spirit of the invention.
What is claimed is:
l. The combination with a vehicle supported grain holding box including a platform and a side wall carried by said platform adjacent a side edge thereof, of an upstanding brace arranged exteriorly of and abutting said side wall and secured to said wall, the lower end of said brace being spaced above said platform, a horizontally disposed foot plate secured to the lower end of said brace, a bolt supported in said foot plate and extending through said platform and adju-stably secured to the latter, a second bolt spaced from said first bolt and extending through said foot plate and having a head resting upon said platform, and a nut in threaded engagement with said second bolt and having its upper face bearingagainst said foot plate.
2. The combination with a vehicle supported grain holding box including a platform and :a side wall carried by said platform adjacent a side edge thereof, of an upstanding brace of L-shape construction arranged exteriorly of and having one of its legs abutting said side wall and secured to said wall and having the other of its legs projecting perpendicularly from said wall, the lower end of said brace being spaced above said platform, a horizontally disposed foot plate integrally secured to the legs of said brace at the lower end thereof, a bolt supported in said foot plate and extending through said platform and adjustably secured to the latter, a threaded bolt spaced from said first named bolt :and extending through said foot plate and having a head resting upon said platform, and a nut in threaded engagement with said threaded bolt and having its upper face bearing against said foot plate.
