Application inea June es, 1906. serial No. 323,921.

To @ZZ whom it may concern."

Be it known that I, JOHN HEBERLING, of Rochester, in the county of Monroe and State of N ew York, have invented certain new and useful Improvements in Dumping- VVagons; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the reference-numerals marked thereon.

My present invention relates to dumping wagons of that class in which the bottom sections or doors are moved by suitable means to normally close the bottom of the box and which may be released to deposit its contents.

The. invention has for its object to provide an equalizing device adapted to cooperate with the means for closing the doors or sections whereby they may be closed tightly in engagement with the box and it has for its further object to provide devices for controlling the operating means of said doors to automatically cause one door or section to be brought to a closed position in advance of the other.

To these and other ends the invention consists in certain improvements, in construction and combinations of parts, all as will be more fully described, the novel features being pointed out in the claims at the end of this specification.

In the drawings: Figure 1 is a front elevation of a wagon box showing devices constructed in accordance with my invention applied thereto, the doors or bottom sections being in a closed position. Fig. 2 is a similar view illustrating the position of the parts during the operation of closing the doors or bottom sections. Fig. 3 is a rear elevation of the wagon box. Fig. t is a detail view of a portion of the equalizing device. Fig. 5 is a sectional view taken on the line 5X 5X of Fig. 1. Fig. 6 is a detail view similar to Fig. 1 showing a modified arrangement of the door operating chains or connections. Fig. 7 is a modified construction of the equalizing device. Fig. 8 is a top plan view of one of the end boards of the wagon box showing another means for supporting the eqnalizing device, and, Fig. 9 is a vertical sectional view taken on the line 9 9X of Fig. 8.

ln illustrating my present invention I have shown it applied to a wagon box constructed with side pieces 1 and 2 and the forward and rear ends 3 and 4 respectively. The bottom is composed of two longitudinally extending sections 5 and 6 which are pivotally supported by hinge members 7 journaled, as indicated at S, on pint-les located a short distance above their lower edges. The bottom sections or doors meet at a central point and the joint formed between them is closed by a batten 9 arranged on the door 5. The sides 1 and 2 of the box project beyond the forward end 3 thereof and supported therein are bearings 10 in which is ournaled a revoluble winding shaft 11, provided at one end with a ratchet wheel 12 secured thereto by a pin 13 passing through its hub. The operating member for rotating the winding shaft is a lever arm 14 having a bifurcated end 15, tle side pieces of which extend at opposite sides of the ratchet wheel and are journaled on its hub. Between the arms of the lever is a pawl 16 and underlying the latter is a finger 17 on an arm 18, pivoted to one of the side pieces of the lever, and having a rearwardly extending end 19 which is adapted to cooperate with the upper edge of the end 3, of the box, to raise the arm and disengage the pawl from the ratchet wheel when the lever is moved into the position shown in Fig. 5. Arranged beneath the ratchet wheel is a locking dog 20, normally held in the operative position by a spring 21, having at its outer end a iinger 22 projecting beneath a shoulder 23 on a pivoted treadle 24, the depression of which moves the dog into inoperative position. Also pivoted in proximity to the ratchet wheel is a brake shoe 25, adapted to be operated into engagement with the rim of the ratchet wheel when the lever 211 is depressed, by a cam shoulder 26 on the latter.

Located on the shaft 11 are two conical winding drums 27 and 28 provided with helical grooves arranged with their smaller ends in proximity to each other and separated a short distance as shown. riihe particular shape of the drums however is not essential and they may be otherwise formed or omitted as desired. Attached to the larger ends of each of the drums are the winding chains or operating connections 29 and 80 which are suspended and extend downwardly beneath the forward ends of the doors or bottom sections 5 and 6 and pass longitudinally thereof to the rear ends of said doors whore the extremities of the chains are carried upwardly and attached to the rear end 4 of the box, as shown in Fig. 8. It will be understood, however,

that the chains might be conn-eoted otherwise than by being anchored directly on the wagon box, for if they were connected to some part contiguous to the box, which would form a. support, the result accomplished would be the same, as the object to be attained is the suspending of the ends of the chains from points above the doors whereby the latter may be closed tightly against the box. At one end of the latter the connecting of the chains to the box is accomplished by means of the winding shaft 11. Both of the rear ends of these chains or connections may be attached rigidly to the rear of the wagon box by eyes, such as 3l, but in practice l find it preferable to provide means for adjusting the end of one of the chains, as it is difficult to proportion their length so that when the winding shaft is rotated to close thc doors tightly, the dog 2O will engage in one of the ratchet teeth without permitting lost motion of the shaft l1 nearly equal to the length of one of the teeth of the ratchet wheel. To provide for this adjustment I attach to the end of the chain 29 an eye 32 having a threaded pin 33 projecting through the outwardly extending foot of a bracket piece 34 and coperating with a nut 35.

At one end of the wagon box, preferably the forward end thereof, where the winding shaft is located, is provided a device which cooperates with the two chains or connections for equalizing inequalities in the lengths of either of them, resulting from unequal wear, stretching or other causes. This equalizing device is movable in a direction transversely of the chains and in the present preferred embodiment of my invention comprises a depending arm 40, journaled on a pin 4i supported in a bridge piece or strap 42, having at its lower end laterally extend` ing arms 48 and 44, the extensions of which are overlapped, or bent into a U-shape, to receive the journal pins 45 and 4G of small rollers 47 and 48. The rollers are sepa` rated a distance somewhat greater than the distance between the proximate ends of the drums 27 and 2S so that when the chains or connections are wound upon the latter, their depending portions are extended laterally. Arranged beneath the rollers 47 and 48 are sheaves 49 and 50 mounted upon pins 5l and 52, supported in the strap 53, rigidly connected to the end 3 of the box. The rollers 49 and 50 are located in alinement with the proximate ends of the two winding drums and consequently are brought closer together than the rollers 47 and 48. It is their object to guide the chains upwardly from the forward ends of the doors to a Y fixed point on the wagon box, relatively to the winding drums, so that when the doors are open the chains or connections will not be permitted to draw away from the rollers 47 and 48. The depending portions of the chains, or connections, extending between the winding drums and the fixed rollers 49 and 50, or the proximate ends of the doors, form spans which if drawn laterally to one side or the other, at an intermediate point, will cause the remainder of the chain or connection to be shortened or drawn independently of the other connection. if the spans of both connections are given an equal lateral movement their respective lengths will remain equal and the winding or drawing up of the two connections will close the doors or bottom sections simultaneously. Thus dit will be seen if the span of one connection is moved laterally a greater distance than the corresponding span of the other section, one of the bottom sections or doors will be caused to close in advance of the other. By arranging a device between the spans of the two connections which is movable relatively transversely of said connections, it may be shifted by one of them, when the tension imparted thereto tends to draw the intermediate offset portion of its span into a straight line, the shifting or transverse movement of the member causing the offset in the other span to be increased until an equalization between the two connections has been effected.

In order to close one of the doors or bott-om sections in advance of the other, by temporarily shortening its connections, as above described, I have provided means which normally tend to move the equalizing device in one direction comprising, for the purpose of illust-ration, a spring 55 attached to the forward end 3 of thewagon box at the point 56, said spring preferably extending upwardly through the strap 42 over the top of the arm 40 and connected to its opposite side, shown in Fig. 4. lll/Then the tension is relieved from the chains or connections the resiliency of the spring 55 shifts the arm 40 to the normal position shown in Fig. 2 permitting the span of the chain 29 to be lengthened out while the span of the chain 30 is taken up. rlhe equalizing device remains in this position until the door G is closed in engagement with the bottom of the wagon box. The continued rotation of the shaft l1 simultaneously winds up the chains 29 and 30 and the tightening of the latter while bearing against the roller 4S causes the equalizing device to be shifted, the roller 47 thereon causing a lateral movement of the chain 29 so that when the doors are closed, as shown in Fig. 1, the span of the two chains are offset approximately equal distances in opposite directions. It will be seen from this construction that if the chains se are of unequal length, the equalizing device will yield to one side or the other, permitting both the bottom sections or doors to be tightly closed against the bot-tom of the box. A further advantage is obtained by the arrangement of means, such as I have provided, whereby the length of one of the chains may be adjusted, as sho-wn in Fig. 3, as it may be taken up or let out so that when the sections or doors are closed the spans of the two chains or connections will be drawn laterally equal distances by the equalizing device, the whole presenting a symmetrical appearance.

In Fig. G I have shown a modified arrangement of the chains or door operating connections whereby the rollers or fixed bearings sti) and 50 may be dispensed with. In this view the chains 29 and 30a, dependingl from the winding shaft lla after passing the rollers or guides 47a and 48a of the equalizing device eti-3, are crossed and extended respectively into engagement with the doors or bottom sections G and 5a. By this arrangement it will be seen that the chains always draw across the guides of the equalizing` device in opposition to each othell whether the doors are opened or closed.

The lateral displacement of the spans of the chains or door connections may be accomplished in different ways than by separating them, as shown in Figs. 1 and G, and in Fig'. 7 I have illustrated an equalizing device in which the guides or rollers 47D and 481 are arranged to draw the chains 291 and 30b into proximity to each other to accomplish the results heretofore described.

The arrangement of the equalizing device whereby it may be automatically operated by either of two chains or door connections permits it to be conveniently located at one end of the box and as its movement is in a direction transversely to the two connections it may be supported either as described as above, or in a manner similar to that shown in Fig. 8. In this modication the rollers or guides 47C and JISC are mounted on a plate or member 43C movable longitudinally in guides 43d attached to the wagon box.
