SPECIFICATION forming part of Letters Patent No. 365,233, dated June 21, 1887.

Application filed October 27, 1886. Serial No. 217,302. (No model.)

To @ZZ whom it may concern.'

Beit known that I, JOSEPH M. BLAKE, a citizen ofthe United States, residing at Bu'tlalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Duniping-Vagons for Coal, die.; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thercon,which form apart of this speciiication.

lvIy invention relates, particularly, to that class ofdumping-wagons which are adapted for carrying coal, sand, garbage, and, in fact,`any similar materialof a broken nature requiring a box; and the object of my invention is not only to provide an improved construction which will be simple, inexpensive, and effect ive, but to adapt it as well for direct application to any style of wagon now in use for the purposes above outlined; and to that end my invention consists, substantially, of a frame adapted for direct application to the bolsters of a wagon, such frame having connected and arranged therewith the operative parts for manipulating|` the box arranged upon the frame in the operation of dumping its contents.

I will now proceed to definitely describe, with the aid of the drawings, the manner in which I propose to carry ont my invention.

In the drawings, Figure 1 represents a side elevation, partly in section, Yof a wagon to which my improvement is applied. Fig. 2 is a top plan view of the frame and its operative parts, shown independent of the wagon. Fig. 3 is a back view of Fig. l with the wheels removed, and Figs. at and 5 are detached detail views.

Referring to the drawings, a a are the wheels, a the front bolster, al the rear bolster, a the-reach, and a" the box, of a wagon of ordinary construction to which myinvention is to be applied. It will be remembered that While I have herein shown this ordinary construction ot'wagon to illustrate the application of my invention, I do not wish to thereby confine myself to such restricted application, as it will beseen later on that the adaptability of my improved apparatus is susceptible of a very wille range.

I will now describe the frame and its attached operative parts, which is to bc secured directly to the bolsters of the wagon, the box of the wagon being provided with suitable attachments to cooperate therewith. Of this frame, b b are the side sills, the front ends of which are to be directly secured to the front bolster, a', and b2 b'Z are the cross-pieces employed for strengthening` the frame.

c c are a pair of friction'rollers placed upon each ofthe sills b b. rlhese rollershavc flanged ends c', and are pivoted a. certain distance apart in the side pieces, c2 c, and from the center of each of these side pieces and extend ing downwardly and inwardly are the keepers c c3, the inner ends of which enter the side grooves, b b', of the sill b. By reason of this arrangement these frictioirrollers c c are permitted to roll upon the top surface ofthe sills b b without strain upon their frames ci c2 c, and are confined to their operative position by such frame and their flanged ends, and their length of travel is governed by the stops cl c, secured to the top faces of the sills b b.

The box a" is provided upon its under snr face on either side of its front end with the bearingcleats d, which rest upon the frictionrollers c c between their flanged or flaring ends. and its load backwardly in order that it may be dumped is thus materially lessened.

The rear ends of the sills b b are each incascd in the metallic bearing-plates c c, which cover the bottom and side surfaces only of the sills, and to which they are securely bolted. These bearingplates, with the inelosed sills, are securely fastened to the rear bolster, a2, by the bolts c c, which pass through the bearingplates e c, the sills b I), and the metallic plates c c, cxtending across the under side ofthe bolster at. Upon the outer ends of the bearing-plates c c,

and upon each side thereof, are the projecting 9 journal-boxesf, provided with the removable caps j". (See Fig. 3.)

g is a shaft extending across the frame and seated within the journal-boxes ffof the bearingplates c e. Itisloosely secured in such posi- The power required to move the boxv ICO tion by bolting down the caps f. Between the projections f f at either end of the shaft g, and rigidly secured thereon, arewheels, each having the raised central row of teeth or cogs, h, and the smooth bearing-surfaces h' h4 on either side of the teeth 7i.

Upon either side of the lower surface of the box, at its rear end, are secured the rack-bars '7c le, having the central rows of sockets, 7s', and.

the fiat bearing-surfaces k2 k2 on either side. (See Fig. 3.) The teeth and sockets may be reversed in position without altering their respective functions. Vhen the box Z4 is in position, the teeth or cogs h intermesh with the sockets 7c of the rack-bar, and the surfaces 102k rest upon bearing-surfaces h h of the wheel, these surfaces being intended to bear all the weight as the box a" is moved, the upper edges of the teeth not coming in contact with the upper walls of the sockets in the rack-bar plate. Extending from the ends of the rack-bar inwardly and downwardly on each side of the box are the arms/Z, their ends being joined by the cross pieces or bars Z. The shaft g extends between these cross-bars Z Z' and the box and between the arms Z Z on either side, the cross-bars serving as guides and the arms as keepers for the box in the operation of dumping, as well as at all other times. The device which I employ to turn the shaft g in order to move the box a4 upon its bearings is preferably a double ratchet and pawl lever.

Referring more particularly to Fig. 4, it will be seen that the operative parts of the lever are confined withintwo plates, of which m is the inside plate, the similar outside plate, m, (shown in Fig. 2,) being removed to show the arrangement of parts. Between the forward ends of these inclosing-plates is secured the handle m', the outer ends of these plates surrounding and working loosely upon the shaft g. Rigidly secured to the shaft g, between the plates m m, is the ratehetwl1eel fn.v rlwo dogs or pawls, o o, are pivoted between the plates,

their rear ends being adapted for engagement with the ratchet-wheel n, and their forward ends having attheir outer sides the cam-surfaces o o and at their inner sides the sockets oIl o2, adapted for the reception .of the spiral spring o, placed between them.

p p are thumb-pieces lpivoted in the plates m m, their inner ends having the cam-surfaces p p', for engagement with the camsurfaces o o. The thumb-pieces p, operating with their cam-surfaces against the cam-surfaces of the pawls, throw them in or out of engage ment with the ratchet-wheel.

As seen in Fig. 4, the upper pawl is in engagement with the ratchet-wheel, and by throwing the lever-handle m up the shaft g is revolved in a direction which causes the box a4 to be moved backward. By throwing the lower pawl into engagement with the ratchetwheel n and the upper pawl out of engagement therewith, the box can be moved in the opposite direetion,and by throwing both pawls into engagement with the ratchet-wheel n and fastening the lever m in a rigid position the box a* is held in its proper place.

As will be seen from the foregoing description,the forward end of the box,with its load, rests upon the frietiongrollers c c, and the rackbars k upon the rear end ofthe box rest upon and are operated by the gear-.wheels hhhthrough the medium of the hand-lever m and intervening mechanism, the lever 0perating,as described, to move the box in `either direction. The movement of the box upon the frame is limited by the keepers Z Z and guide-bars Zl Z. Vhen the operating lever m has moved the box a* backward until the forward keepers, Z Z, strike against theinclosed shaft g, the box, with its load, tips up into the position shown by dotted lines in Fig. I, and the load slides out by its own gravity, after which the empty box is easily thrown into a horizontal position and moved back to its normal position by the lever m', as has been already explained.

1Y am aware that a box has before been arranged in various ways so that it could be moved horizontally upon its bearings 'over the wheels and tipped so as to discharge its load; but in each instance a special construction of wagon was necessary, involving more or less additional expense outside of the cost of the dumping apparatus. In my improved construction this is avoided, as my improved apparatus can be directly applied to any wagon without any material increase over the initial cost ofthe special apparatus for dumping.

I claim-- l. A dumping-wagon having a box, a frame secured to the bolsters, anti-friction devices adapted to support the' front of the box in its reciprocatory movements Aand while at rest, rack-bars secured to the rear of the bottom of the box, vertical bars extending downwardly A metallic bearing-plates secured lto the bottom and sides of the sills and extending rearwardly thereof to form journal-boxes for the operative shafts, the operative shaft having toothed wheels thereon to engage the rack-bars on the wagon-box, and extending in a transverse direction between the vertical and crossbars and beyond the axle, and serving as the fulcrum or pivot upon which the box tilts, and devices for rotating said shaft, substantially as and for the purposes set forth.
