WILLIAM OSCAR SHAlDBOLT, on NEW YORK, N. Y.
DUMPI NG WAGON.
SPECIFICATION forming part Of Letters Patent NO. 665,137, dated January 1, 1901.
Application filed. November 4, 1899- Serial No. 735,773. (No model.)
To all whom it may concern:
Be it known that 1, WILLIAM OSCAR SHAD- BOLT, a citizen of the United States, residing in New York, borough of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Dumping-Wagons, of which the following is a specification.
This invention relates to the general class of four wheeled dumping wagons with springs at the back between the dumpingbody and the frame; and the object of the invention is to provide a dumping-wagon having the body mounted on full springs at a point in front of the rear axle, the springs being supported at the pivotal axis substantially below the center of gravity of the body and rocking with the body, being secured at both ends thereto. The body turns on but one fulcru m-point in dumping, and means are or may be provided for limiting the extent to which the body tilts in dumping, so that its rear end or tail may not touch the ground. Means are or may be provided also for automatically releasing the tail-board in do mping.
In the accompanying drawings,which illustrate an embodiment of the invention, Figure 1 is a side elevation of the wagon as it appears normally, and Fig. 2 is a similar view showing the body dumped. In both of these views the near wheels are omitted. Fig. 3 is a rear view, the rear end of the body being in transverse section. Figs. 4 and 5 illustrate a way of connecting the ends of the spring to the body, which differs slightly from that shown in the principal views. Fig. 4 is a longitudinal section of the rear portion of the wagon, and Fig. 5 is a transverse section just back of the hind axle. Figs. 6 and 7 illustrate a construction in which the bar carrying the rear springs is fixed in the frame, the springs rocking thereon. Fig. 6 shows the bar in cross-section, and Fig. 7 shows the spring in cross-section.
The construction as illustrated in Figs. 1, 2, and 3 will be first described.
1 is the body; 2, the frame; 3, the front axle; 4, the front wheels; 5, the hind axle, and 6 the hind wheels. The front end of the frame 2 is relatively elevated and is supported on tion 8 being interposed between the frame and the springs. At the rear the'frame is depressed and rests directly on the hind axle. In the frame in front of the hind axle and substantially under the center of gravity of the body is mounted a rocking bar 9, to which is secured by clips or the like the full hind or rear springs 10, the ends of which are secured to the body at a; x. As the body projects well back beyond the rocking bar 9 and is supported at the hinder end only by the springs 10, these latter will be by preference extended farther to the rear of the bar 9 than-to the front thereof. The front end of the body will be supported normally on a transverse member or members in the frame.
The bodyis seen dumped in Fig. 2, wherein it will be noted that the center of oscillation (the axis of the bar 9) is much below the level of the bottom of the body, so that as soon as the body begins to dump the center of gravity passes to the rear of the fulcrum or pivotal point. It will also be noted that the hind springs 10 rock with the body throughout the entire (lumping movement, which takes place about a single oscillating point or fulcrum. This construction lends simplicity and strength to the structure. The rear axle is cranked, so as to afford room for the rear or hind springs in dumping.
To prevent the tail of the body from striking the ground in dumping, limiting-chains 11 are or may be employed.
When the tail-board of a dumping-wagon is set free at the moment of the dumping move- .ment, some portion of the load at the hinder end of the body is liable to escape prematurely and thus shift the center of gravity forward before the entire load can be dumped. To avoid this, the tail-board 12 is or may be provided with an automatically-detaohable fastening device which may be set to act so as to free the tail-board at any point in the dumping movement that may be desired. This device consists, as herein shown, of a lever-latch 13 on the body, the beak or nose of which engages an eye or staple 14 on the tail-board, as seen in Fig. 1. To operate this latch to disengage it, its arm is connected by springs 7, the ordinary fifth-wheel construc- I a chain or the like to some point on the frame, as the bracket 16. Thereshould be two devices of this kind, one at each side of the body.
It will be noted that an important feature of my construction is the mounting of the body at the rear end on full springs, the body being secured to both ends of the springs, and in the fixing of these springs to a simple rocking bar in the frame about under the center of gravity which is between the axles. Thus the body and springs rock together about one point of oscillation and the load is distributed evenly.
The principal views show a known means for connecting the ends of the springs to the body,so that they will rock therewith throughout the entire dumping operation, and the body will always remain seated thereon; but in Figs. 4 and 5 another construction is shown wherein the connection is made by passing the ends of the springs at m loosely through keepers 17 on the body. To prevent the body in dumping from exerting an undue endwise pressure on the front arms of the springs, hinged links 18 may be employed, one end of the link being coupled to the body at y and the other end to the bar 9. These links are shown only in Figs. 3, 4:, and 5,being omitted from Figs. 1 and 2 in order to avoid confusion.
I am well aware that it has been proposed to mount the body of a dumping-wagon on springs fixed to a rocking bar in the frame, the first part only of the dumping movement being about this bar as a fulcrum and the remainder of said movement about the point where the rear or hinder arms of the springs are pivotally connected to the body. The body in tilting leaves or lifts off from the front arms of the springs, not being connected at all therewith. This construction is objectionable in having two fulcrum-points and in being structurally weak. In my construction it will be noted that the springs remain always connected with the body throughout the entire dumping movement. In the construction of Figs. 4 and 5 means are provided to keep the body and springs together, although the coupling is not a rigid one. Obviously one arm of the spring may be securely coupled to the body and the other arm has a sliding connection therewith. The front arm, for example, might be coupled securely to the body and the latter be merely slidably supported on the rear or hinder arm. Obviously, also, the springs may be mounted so as to rock on and about the fulcrum-bar, the latter being fixed. This construction is seen in Figs. 6 and 7, wherein the bar 9 is cylindrical and has a block 19, mounted to rock on it between suitable collars 20. The spring 10 is secured to the block by clips or other means. This construction will operate and produce the same result as that shown in the principal views. The links or struts 18 will in this construction be connected to the fulcrum-bar 9 by means of collars which turn on the bar. Where the bar 9 rocks, the connecting-collars rock with it.
Having thus described my invention, I clai1n 1. A dumping-wagon having its frame supported at the rear on the hind axle, afulcrumbar mounted in the frame between the axles and forming the sole dumping-fulcrum of the body, full hind springs supported on said bar, and the body mounted on the front and rear arms of said springs and supported there on during the entire dumping operation.

4. A dumping wagon having a cranked hind axle, a frame mounted at its rear end on said axle, two full, hind springs mounted to rock in said frame at a point in front of the hind axle, and the dumping-body mounted on the said springs and connected to the front and rear arms thereof, whereby the said body is carried solely by said arms during the dum ping movement.
