Application filed July 13, 1907, Serial No. 383,604.

To all whom t may concern:

Be it known that I, JOHN HEBERLING, of Rochester, in the county of Monroe and State of New fork, have invented certain new and useful improvements in Dumpingvv'vagons and I do hereby declare the following to be a tull, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of the specication, and to the reference-numerals marked thereon.

The present invention wagons of the type employing bottom sections movable to discharge the contents of the wagon box and operated by flexible connections, the tension on which is equalized by a suitable means which preferably also acts to close one section in advance of another; one object of the invention being to provide an equalizing means which will be simple and effective in operation and durable in use; another` object being to improve the manner of etlecting the closing of one section in advance ot another; and a further object being to provide an improved means for locking the winding shaft against accidental release due to causes.

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

in the drawings; Figure l is a top view of a wagon body constructed in accordance with my invention. Fig. 2 is a central longitudinal vertical section of the wagon body shown in Fig. l. Fig. 3 is a vertical section in the plane of the winding shaft, showing the bottom sections closed; Fig. t is a transverse vertical section in rear ot' the end wall of the body; Fig. 5 is a detail section showing the pawl operating device in a position permitting the movement of the ratchet in the direction of winding only; Fig. 6 is a like view showing the pawl operating device in the position in which the ratchet is released; Fig. 7 is a section similar to Fig. 3 showing the bottom sections in open position; and Fig. 8 is a section similar to Figs. 3 and 7 showing another embodiment ol my invention.

rl'he invention which is susceptible of being embodied in various constructions, in the form shown in Figs. 1 to 7 comprises a relates to dumping I jarring or other l wagon body or box having its side boards l preferably extended.at both ends and connected by cross pieces 2 to which suitable running gear may be secured. Two bottom sections or doors 3 hinged at 4l to the side boards so as to swing outwardly and discharge the contents of the box, are closed by suitable Vflexible connections preferably two separate chains 5 and 6 each of which in this instance, is secured at one of its ends to one of two hooks 7 arranged on the tail board of the box. The chains pass beneath the sections and at their forward ends are connected to the means employed for drawing or shortening in the connections for the purpose of closing the bottom Sections or doors, comprising a winding shaft 8, journalcd at the forward end ot' the box and carrying a pair of conical drums 8a and 8b to the larger ends of which the connections 5 and 6 are secured. In the present embodiment of the invention the flexible connections are guided along the free edges of the sections and for this purpose the ends of the latter may carry guide rollers 9 over which the connections pass, loops l0 being arranged between and adjacent to the rollers to prevent the sagging of the connections, rollers ll being arranged on a bracket l1a on the front board and serving to guide the forward ends of the connections and retain them in a central position on the box at all times.

The winding shaft 8 is located a short distance in front of the forward end of the wagon box and the ends of the chains or connections extend in a rearward and downward direction to their points of engagement with the doors, or the guide rollers 1l in the event it is desired to employ the latter. In the space thus provided between the shaft and the end ot' the box is located means for equalizing the tensions applied to the door operating connections which in the present embodiment or' the invention comprises two supports, or guides over which the separate chains are passed, said supports being connected and capable of movement in opposite directions for the purpose of taking up one chain or connection and paying out the other, as will be more fully described. In its preferred form the equalizing device comprises the supports or guides l2 and 13 which may be in the form of rollers turning about axes arranged at the ends of an arm let and extending transversely to the longitudinal axis of the box. The arm le is an oscillatory lever journaled on an axis 15 which is slightly inclined to the horizontal and is supported by a bracket 1G. It is apparent that, with the bottom sections in the positions shown in Fig. 7, if the winding shaft 8 is rotated in the direction of the arrow Fig. 2, the flexible connection will be wound about the drums Sa and 8b, first fast and then gradually slower owing to the varying diameter of the drums, and should one connection have more tension applied thereto than to the other, due to stretching of one connection, or other causes, the equalizing means will take up a portion of the other connection.

The free edge of one of the sections is provided with a batten strip 17 which when the sections are closed covers the joint and prevents leakage. The use of this strip makes it necessary to close one section in advance of the other and this can be accomplished automatically by any suitable device designed to set it in the position shown in Fig. 7 whenever the doors are openec. ln the arrangement of parts which l prefer to employ for accomplishing this object, l mount one of the supports or guides so that it may move toward and from the axis of the arm or lever 14, for instance, when the support is in the form of a roller, as shown, l permit the latter to move axially on its bearing. rlhe winding of the chain 6 on the shaft 8 causes its successive convolutions to lie one beyond the other so that when the chain is drawn tight it will also extend laterally and shift the roller 13 outwardly on the lever relatively to the axis thereof.l As the position of the support 12 on the lever does not change, it follows that when the support 13 moves nearer to the axis than the device 12, as is the case when the winding shaft is released, the equalizing mechanism in this instance the lever will be shifted so as to pay out the connection 5 and take up slack in the connection 6 or the one operating the section without the batten strip; and upon the winding of the connections this section will close in advance of the other. From the above it will be apparent that the movable support 13 serves as a means for automatically varying the leverage of the equalizer.

As a preferred means for operating the winding shaft provide the latter with a ratchet wheel 1S and journaled on said shaft is a swingi'ng lever 19 carrying a dog 2O engaging with the ratchet to rotate the latter. ln order to maintain the shaft against rotation there is provided a pawl lever 21 pivoted at 22 on the forwardly extending end of the side board of the box at one end of which is a movable nose 23 permitting the release of the ratchet without undue wear on the teeth of the latter. The position of l l l l the lever is controlled by a device movableto three positions, in one position holding the pawl out of engagement with the ratchet, in another holding the pawl in engagement with the ratchet while permitting its movement only in the direction of winding the shaft, and in the other holding the pawl in engagement with the ratchet against any movement, so that when the wagon is loaded its contents cannotbe deposited by the accidental release of the ratchet by jars or other causes. This device comprises a swinging member 232L pivoted intermediately of its ends to the side board and carrying foot pieces 24. by which it is operated, and an eccentric projection 25 which is adapted to work in a bifurcation in the outer end of the pawl lever 21. ln locking position, the swinging device lies against the lower arm of the bifurcated end as shown in Fig. 2; in winding position midway between the arms as shown in Fig. 5 and in releasing position against the -upper arm as shown in Fig. 6.

ln Fig. 8, have shown a modified form of the equalizing mechanism in which the movable supports 12a and 13a are united by a flexible connection 14a and the equalizing means thus formed may be made to effect the closing of one section before the other by attaching a flexible connector 26 at one end to the equalizing means and at the other end to the section carrying the batten strip or the door which is desired to close last, so that when the sections drop the vertically movable device 12a will descend paying out its flexible connections 5CL and the device 13a will flex or take up its flexible connection G causing the section operated by the latter to close in a-dvance of the other. The winding shaft employed for drawing on the flexible connections 5a and 6a is indicated in this figure by 8a.

lt will be noted that the flexible connections instead of passing directly downward extend rearwardly from the drawing means preferably over supporting guides revoluble about axes transverse axis of the wagon box, so that l am enabled to arrange the drawing means beneath the drivers seat removing the operating lever at one end thereof to a posit-ion where the wagon box does not interfere with its movement whereby a long stroke may be given the lever enabling the operator to close the doors quickly.
