rnncK-BonY CONSTRUCTION.

Application filed January 5,

To all whom it may concern:

Be it known that I, GARFIELD A. Woon, a States, and residing at Detroit, in the county of,Wayne and State of Michigan, have invented a new and Improved Truck-Body Construction, of which the following is a specification.

The present invention relates to truck, bodies, more particularly to the type of body which is tiltablc about a transverse horizontal axis near its rear end and in which the latter is closed by a door that, is swingable about a horizontal axis near its upper edge. It is, however, applicable to car bodies and other tilting hoppers.

The object of the invention is to provide a strong neat appearing body from which the material is rapidlyand eompletelydischarged at the rear as the front end is lifted, and to which a standard door construction is applicable regardless of considerable variation in the depth. The invention will be inore fully understood from a consideration of the fo lowing description of a preferred embodiment, and from the attached claims wherein the novel features are more definitely pointed out.

In the drawings, Figure 1 is tary side view of the rear end of a truck showing a preferred embodiment of the invention. Fig. 2 is a rear elevation of the body. Fig. 3 is a central longitudinalvertical section corresponding to Fig. 1, the body being in elevated position and the door being open. Figs. 4c and 5 are sections on the lines H and'55, respectively, of Fig, 1.

The side bars 1 of .the body are swingable about horizontal pivots 2 that are mounted in brackets 3- in the usual way. it being understood that the brackets in turn are secured to the rear end portion of the chassis frame 3 Extending across the side bars at intervals are the cross bars 4 whereon the hopper 5' rests and to which it is riveted or otherwise secured. In order to insure a properdischarge of bulk material," say coal or earth, therefrom. it is preferred to cona fragmenstruct the mam portion of the body of what either is, or .is 1n effect, a metal; that 1s, if any seam arranged longitudinally of single sheet of is present it' s the body'so a..-

may become lodged. This general construetion is well-known.

Were the sides simply extended upwardly each in a. single vertical plane, the construction would be relatively weak; and in order to strengthen the hopper against bulging, as well tlSflfOll' the purpose of materially increasing the capacity, particularly with reference to top load, the upper portions of the metal of the sides are inclined outwardly at 8, then bent inwardly to form horizontal webs S) and finally turned downwardly, as away with the sharp edges that might otherwise cut into bags of cement or the like, and to give strength against bending.

The side construction continued fully to the greatly complicate the construction of ing; again. the capacities. the

The plate 15 may be omit-ted. Those portions of each flange 9 on opposite sides of the.cor-

are finally connected by 16. Then by rivetmg or welding around the extreme rear endthe reinforcing bar 17, preferably-of angle cross-section. and by continuin it upwardly to the top of the portion or plate 15, there cross bolt,

The metal of the body is slitted at 26 opposite the bar 17 to pressed smooth a upper allow it tobe bar, during which operation the slit assumes the form of all as shown in Fi 3. en any suita 1e hoisting mechanism 1(not shown) and the door is pet free, the latter swings out into the position indicated in Fig. 3 and provides a large opening through which the material may freely fiow. By making the upstanding portion the same height in all cases, it is evi entthat a door suitable for one size of body is equally well adapted to another.

The construction of the door may vary; preferably, however, it comprises a sheet metal plate 20 the upper edge of which 15 turned inwardly at 21 over the bolt 1$-and This plate may be reinforced by the fiat U- shapedba'r 23 conforming substantially to and arrange and may have riveted or -welded thereto a striker bar 24 with which the latch 25. (preferably that disclosed in my U. S. Patent No. 1223462. granted April 24, 1917 )1 cooperates.

' The details of construction may be varied to some extent withoutfldeparting from the spirit of my invention, and Ido not, therehe bar 17 fore, wish to be limited otherwise than as indicated by the subjoined claims.
