WILLIAM E. BRELSFORD, OF TRIUMPH, ILLINOIS.

WAGON-BODY.

To all whom it may concern:

Be it known that I, \VILLIAM E. BRELS- roan, a citizen of the United States, residing at Triumph, in the county of Lasalle and State of Illinois, have invented new and useful Improvements in lVagon-Bodies, of which the following is a specification.

The invention relates to an improvement in wagon bodies, and is particularly directed to a hinge construction for connecting the platform and sides of the body so that the latter may be conveniently arranged at right angles to the platform to form a box body orin the same plane with the platform to provide an increased carrying surface.

The main object of the present invention is the provision of a hinge construction forming the connection between the platform and sides in the operation of which the side may be turned down into a plane practically coincident with that of the platform and at the same time moved toward the platform to form a practically unbroken surface when the side is extended.

The invention will be described in the following specification, reference being had particularly to the accompanying drawings, in which Figure 1 is a view in elevation, with the wagon platform and side in section, illustrating the application of the hinge. Fig. 2 is a vertical sectional view through the hinge and connected parts. Fig. 3 is a side elevation of the brace block. Fig. t is a broken perspective of the lower end of the hinge member which is secured to the side board. Fig. 5 is a broken perspective of the hinge member which is secured to the platform. Fig. 6 is a broken perspective showing the lower end of the brace member. Fig. 7 is a perspective of the locking pin. Fig. 8 is a broken sectional view showing the hinge members in position to support the side board upright. Fig. 9 is a similar view with the hinge members in position to support the side board in a plane with the platform.

The improved hinge comprises a head member 1 including side plates 2 spaced apart to embrace and be secured to the cross piece or stringer 3 beneath the platform 4 of a wagon body, the side pieces having lateral ears 5 for the reception of screws which take directly into the platform. The outer ends of the side plates are connected Specification of Letters Patent.

by a plate (3 at their upper edges, which plate beyond the adjacent edge of the platform is formed with openings 7 arranged in alinement longitudinally of the platform but in spaced relation. Beyond the outer edge of the plate 6 the side plates 2 of the head are each provided on their inner surfaces with lugs S, which at their outer ends form guard llanges 9, the free ends of which llanges are in line with the outer edges of the plates 2. From the guard flanges the lower surfaces of the lugs 8 curve downwardly, as at 10, and then upwardly, as at 11, and such surfaces terminate coincident with the lower surface of the plate 6 immediately adjacent the outer edge of the opening 7. The upper surfaces of the lugs S are formed, as at 12, Fig. 5, to provide guide surfaces for a purpose which will be hereinafter explained.

Pivotally mounted in the head 1 is a brace block 13 formed to provide an inner plain surface let, the end of the block ad jacent the upper end of the surface 14; being formed with a transverse opening 15, for a purpose which will be later explained. The head 1 is formed with a depending plate 16 to rest against the end of the cross piece 3, said plate having side flanges 17, the distance between the inner surfaces of which corresponds to the transverse dimension of the plain surface 14: of the brace block. On the outer edge the brace block is provided with a projection 18 formed with a transversely arranged pivot opening 19. The brace block is pivotally mounted between the flanges 17 of the head by means of a pin 20, said pin being so arranged that the plain surface of the block may, when the block is permitted to swing freely downward, contact with the outer surface of the depending plate 16.

Secured upon the side board 21 of the wagon is what I term the movable member 22 of the hinge, said member comprising a section of channel iron form having laterally projected cars 23 whereby it may be secutred to the side board. Secured within and centrally of the section 22, preferably formed integral therewith, is a bar which projects below the lower end of the section and is terminally formed with a cross bar 24. This bar is of a length to fit between the side plates 2 of the head beneath the lugs 8, and on its surface next the platform is provided at each end a stud-like projection 25 so spaced apart and of such size as to enter the openings 7 in the head. The end of the section 22 engages the lower edge of the side board and is rounded at 26 to bear upon the upper guide surfaces 12 of the lugs 8. The upper ends of the side walls of the channel section 22 are slightly enlarged and formed with pivot openings 27, to receive the upper end of a brace bar 28, a pivot pin 29 connecting the member 22 and brace bar together at their upper ends. As shown more particularly in Fig. 6 the lower end of the brace bar is provided with spaced laterally projecting ears 30 formed with pivot pin openings 31, said ears being designed to embrace the projection 18 on the brace block and the openings 31 and opening 19 in said projection re ceiving a pivot pin 32 so that the lower end of the brace bar is connected to the brace block. Immediately above the cars 30 the brace bar is provided with a solid projection 33 extending outwardly beyond the free edges of the ears and formed with a transverse opening 34. This opening is designed when the side 21 is in upright position to register with transversely alined openings formed in the side plates 2 of the head, so that when in such position a locking pin, as 36, may be introduced to hold the parts in applied position. The locking pin 36 is preferably identical with the construction of the pin 20, and, as illustrated in Fig. 7 comprises a suitable length of bar formed on one end with a handle 37 and adjacent the handle with a locking pin 38. The opening in one of the side bars 2 is designed to be formed with a communicating recess through which the pin 38 may be passed in introducing the pivot rod, and after the pin is beyond the inner surface of the plate 2, turning of the rod in one direction or the other will lock the same against displacement.

I/Vhen the side board is in upright position it will be noted from Fig. 2 of the drawings that the opening 34 of the projec- "tion 33 of the brace bar is alined with the openings 35 in the side plates, so that the introduction of the pivot rod 36 will secure the parts in such position. In this position the ends of the cross bar 24. of the hinge member secured to the side board rest against the inner surfaces of the guard flanges 9, securing the side boards upright. lVhen it is desired to lower the side boards into the plane of the platform the locking pin 36 is withdrawn, permitting the brace bar to swing downwardly with the brace block 13 until the latter contacts with the outer surface of the depending plate 16. This movement, assisted, of course, by a manual movement of the side board, causes the projecting portions of the cross bar 24 to ride beneath the lugs 8 toward the adjacent edge of the platform, this movement continuing until when the surface 14 of the brace block is in contact with the outer surface of the depending plate 16 the side board 21 is practically in the plane of the platform and the cross bar 24 rests beneath the plate 6 of the head with the studs 25 of the cross bar seated in the openings 7. The side board is thus locked in lowered position with its lower edge in contact with the adjacent edge of the platform to avoid a break at this point.

It is, of course, to be understood that the side boards may be connected to the platform by any desired number of hinges, and that the structure is particularly serviceable with hay rack bodies, though its use is contemplated in any form of wagon body having side boards which it is desirable to adjust to increase the load surface of such body. The various parts of the hinge are to be constructed of any desired material and in any size or shape best adapted for the particular use to which they are to be put.

I claim z- A wagon hinge comprising a head member adapted to be secured against the end of a stringer and below a platform, said head member being formed with side plates, a brace block pivoted to said side plates, said head member being formed with guiding surfaces, a brace bar pivoted at its lower end to said brace block, a bar pivoted to the upper end of said brace bar, a side board secured to said bar, a projection on said brace bar and formed with an opening, a

pivoted rod extending through said open-' ing in said projection, said brace block being adapted to engage the outer surface of the head 1n 1ts innermost position, the lower end of said bar being formed with a rest for said side board, and a rounded cross bar formed on said bar and adapted to contact with the guiding surfaces formed on saidhead.

In testimony whereof I affix my signature in presence of two witnesses.
