SPECIFICATION forming part of Letters Patent No. 637,523, dated November 21, 1899.
Application fil d Se tember 14, 1899. Serial No. 730,420. (No model.)
To all whom it may concern.-
Be it known that I, J OHN OCONNOR, a citizen of the United States, residing in the city, county, and State of New York, have invented certain new and useful Improvements in Dumping-Wagons, of which the following is a specification. V
This invention relates to the class of dumping-wagons wherein the body is pivoted nearly at its center of gravity and is moved to the rear by a rack-and-pinion mechanism at the time of dumping.
The object of the invention is in part to provide a dumping wagon wherein the body may be conveniently lifted off by a crane, lowered into an excavation, filled, and replaced, and in part to certain features of construction, which will be hereinafter fully described.
In the accompanying drawings,which serve to illustrate an'embodiment of the invention, Figure 1 is a side elevation of the wagon. Fig. 2 is a longitudinalvertical section thereof. Fig. 3 is a side elevation of'the rear portion of the wagon, showing the body partly dumped. Fig. 4 is a transverse vertical section of the wagon, showing the body suspended and about to be set on the frame. Fig. 5 is an under side View of the frame and body. Fig. 6 is a detail view of the hooklatch 29.
1 represents the frame; 2, the rear axle; 3, the front axle; 4, springs between the rear axle and the frame; 5, the rear wheels; 6, the front wheels, (indicated only in dotted lines in Fig. 1,) and 7 is the body.
It will suffice to say that the front wheels will be mounted under the frame in the usual manner with a king bolt, hounds, fifthwheel, &c. v
The frame 1 is made at its front end about the same width as the body 7, the front end of which 'rests thereon; but at its rear part it is framed wider, so that the body may pass down between the sides of the frame in dumping. In Fig. 5 these side pieces of the frame at the rear part are clearly shown as overlapping the front part of the frame, the springs lbeingunderandsecuredthereto. Theframe is open at its rear end, so that the body may dump; but there is a tie-piece 1 between its side pieces in front of the rear axle.
The body 7 has a bar 8 extending across it below its bottom, the ends of which rest on the side members of the frame 1 and form trunnions 8, about which the body turns in dumping.
On the inside faces of the respective side members of the frame 1 are mounted in keep ers 9 two like sliding racks 10 10, each of which has at its rear end a fork 10 which engages the bar 8 on the body. Mounted in bearings on the frame is a shaft 11, on which are fixed pinions 1212, which gear with the respective racks 1O 10, and on the shaft 11, exterior to the frame, is a gearheel 13, with which gears a pinion 14 on a shaft 15 on the frame. This shaft is adapted to receive a socket-crank 16. (Seen in Fig. 5.) By means of this crank and the gears the body is moved back on the frame until the trunnions 8 engage and are stopped by keepers 17 on the frame, when the body dumps or may be dumped, as indicated in Fig. 3 and by dotted lines in Fig. 1.
Normally the body is supported at its rear end on the frame by the projecting ends 7 of a cross-bar on the body which rest on the frame, and when these pass off from the side members of the frame the body dumps.
On the rear end of the body 7 is a tail-board 18, which closes it. This tail-board is hinged at its upper edge to the body by means of eyes 19, which engage open hooks 20 on the body. At its lower edge the tail-board is secured to the body by hinged or pivoted latches 21, which engage eyes 22 on the body. The latch 21 is prolonged at its free end, and when the body is dumped this prolonged extremity or arm encounters the beveled extremity of the side members of the frame, as seen in Fig. 3, which serves to automatically lift and disengage the latch, and thus free the tailboard.
The seat 23 for the driver is hinged to a seat-post 24, which is on and rises'from the frame 1, and said seat may be turned forward, as indicated in Fig. 2.
On the framel are upright flared retainers 25, which embrace the body at its base.
It will be seen that the body 7 is left free to be lifted off, and it is provided at its upper edge with eyes 26 to form an attachment for suitable lifting-tackle27. Then the wagon drives up to an excavation to receive its load, the tackle 27 is hooked on, the body lifted off, and lowered into the excavation, filled, lifted out, and replaced, Fig. 4-, on the runninggears. The seat 23 may be turned over to the front, as indicated in Fig. 2, to permit the body to be thus lifted off.
In some cases it is desirable that the body 7 shall not dum p as soon as the laterally-projeeting parts 7 on the body pass off the beveled or inclined rear ends of the frame, and to obviate this the device now to be described may be employed.
On the respective sides of the body are secured horizontally-arranged strips or ledges 28, and on the frame, at the respective sides thereof, are hinged or pivoted spring hooklatches 29, which engage the respective strips 28. These latter are of such length, as herein shown, that the latches will take over and engage the strips 28 and hold the body against dumping until the trunnions 8 shall have got home in the keepers 17, when they will free themselves from the hook-latches and allow the body to du mp automatically. Vithout this precaution the body, which is a little the heaviest at its rear end, might dump prematurely. If the strips'or ledges 28 be extended a little farther toward the front end of the body, the latches will not clear them automatically, and the driver will then have to free the latches by hand to permit the body to dump. Fig. 6 shows in detail a suitable form of spring-latch 29, which will remain so when disengaged. This latch has a spring 29, a flat face 29* to bear on the spring and hold it disengaged, and an operating handle or arm 29 I have shown a latch 29 on each side of the frame, but it would suffice to have but one at one side thereof. The ledge or strip 28 may be any means suitable for engagement I by the latch.
The construction illustrated shows the pivotal point of the body when dumping some what in front of the rear axle; but the axle might be set forward, so as to be practically under the dumping-point. The full springs 4t serve to distribute the load more evenly over the axles than the ordinary construction, as the part of the load back of the axle rests on the rearwardly-projecting arm of the spring.
The keeper 17 is in the form of an inverted L, the upright branch thereof serving as a stop to limit the rearward movement of the trunnions 8 and the horizontal forwardly-extending arm thereof serving to draw the dumped body down on the frame when the body is drawn forward by the racks after dumping.
Having thus described my invention, I claim- 1. A dumping-wagon having rack mechanism for moving the body rearwardly on the frame for dumping, said mechanism having slidable racks in keepers on the frame and provided with open forks engaging a transverse bar on the body, whereby the latter is left free to be lifted off from the frame, substantially as and for the purposes set forth.
2.
