SPZHCZIFTCATION forming part of Letters Patent No. 341,834, dated May 11, 1886.

Application filed October ll, 1885. ScrialNo.179, l35.' (No model.)

To (7, whom it may concern:

Be it known that I, 1VIARTIN CONRAD, of Chicago, in the county of Cook andState of Illinois, have invented certain new and useful Improvements in Dump-Carts; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

The principal feature of improvement herein set forth relates to the support and automatic control of the tail-board. Another relates to the catch by which the body is secured to the thills, and still another to the provision of a permanent]y-attached seat, which may swing up into a vertical position and form a dashboard.

The invention consists in the several matters hereinafter set forth, and pointed out in the appended claims.

In the drawings, Figure l is a side elevation. Fig. 2 is a fragmentary top View. Fig. 3 1s a front elevation. Fig. t is a rear elevatron. Flg. 5 is a side elevation showing the cart dumped.

The letter A is used to designate the connected parts, which constitute the dumping portion or body of the cart as a whole. This dumping or tilting body will commonly be composed, as herein shown, of a frame, the lower side bars of which are marked A, side boards A and a front end-board, A.

B is the wheelaxle, which is secured to the body A, and in that case forms the axis on which the said body tilts.

O O are the thills, which are connected with each other by cross-bars c c, and extend back between the side bars, A, of the body, and are pivoted to the said side bars by a cross-rod or its equivalent at 0 forward of the axle B. Vhen the body A is in a horizontal position, its front end rests on the thills, preferably by a bearing of the frontcross-bar, A", of said body, directly upon the thills themselves, though the main side rails, A, may also, as shown, bear upon the protruding end of the front cross-bar, c, which connects the thills with each other. The said thill-bar c is shown as being arranged with its front face in the same plane with the front face of the crossbar A of the body, and as being provided with a forwardly -projecting pin, 0, intended to serve in connection with some suitable device attached to the body, to hold the front end of said body down until the load is to be dumped.

As one suitable form of catch on the body, D is a bent lever pivoted at its angle to the front face of the cross-bar A of the body, the short arm of said lever depending in the form of a latch or hook, d, in position to engage with the pin 0. The long arm of this lever D, as here shown, extends horizontally beyond the end of the cross-bar A" to form a handle by which said lever may be lifted and the hook disengaged from the pin preparatory to dumping a load.

A vertical strap don thebody forms aguide and retaining device for the long arm of the lever D, and normally thesaid long arm of the the lever rests on a suitable support, as the side bar, A, and may rise and fallfreely. The lower end of the short arm of the lever D depends on thatside of thepin 0 toward thelong arm of said lever, and is made with an inclined surface, (1, whereby the hook engages automatically with the pin when the body of the cart drops forward upon the thills.

Proceeding to describe the principal feature of my invention,which,as stated, relates to the support and automatic management of the tail-board, E E are longitudinal bars arranged one on each side of and at or near the top of the body A, external thereto, and pivoted between their ends to said body on pins or axes of movement transverse to the body, as indicated at e. The tail-board E is fastened securely to the rear ends of these pivoted bars E, and preferably by the construction shown, in which the said bars E extend beyond the 9 depending tail-board and thus afford room for the attachment of the outside braces, c. The front ends of the pivoted bars E are connected by links E with the thills, preferably through the medium of the front crossbar, c, which protrudes at both ends beneath the thills a sufficient distance for the purpose. Thelinks E" are pivoted at their extremities to the ends of the cross-bar c, and also to the front ends of the bars E on transverse pins or axes of I00 movement parallel with the pins 6. By this construction, when the body is tilted to dump I composed of two parts, A and A".

a 1oad,the tail-board E will be upheld by the bars E, while the rear end of the body descends, and on the other hand the tailboard will come back into place against the ends of the side-boards when the body is righted.

Locating the pivotal point e somewhat below the very top edge of the side-boards A as shown, it is desirable to also place it a few inches forward of the axle B,on which the body tilts, and to give the links E a rearward inclination toward their top, so that the endboard will be thrown out clear of the upper rear corners of the side-boards A in the initial part ofthe dumping movement. Ofc'ourse by making the rear ends of the side-boards less in height or downwardly and outwardly inclined these pivotal points can be otherwise located; but both for appearance and utility I .prefer to make the side-boards of uniform height and the tail board vertical, as

. shown.

A further novel feature consists in the construction of the front end board or gate whereby a part thereof may form a seat for the driver. For this purpose said end-board'is The lower part or end-board proper, A", is of the same height as the side-boards A and the upper part, A is hinged thereto or to the side-boards, and made of such length that when thrown down into a horizontal position it will rest at its ends on the side-boards. either to the end-board or to the side-boards, or both, desirably rise in front of the end-board far enough to form a support or stop, the seat part A inits upright position, and one or the other may serve conveniently as a projection on which to loop the lines.

By supporting the tail-board on the board E, as described, said tail-board is relatively moved out of the way of the load to be discharged solely by the operation of dumping the cart, and it is returned to its place, ready for reloading the cart by the act of righting the body. The driver is therefore not called on to manipulate it in any way whatever, and need not release the lines or leave his position near the horse, wherehe will stand to disengage the lever D. When the load is discharged, the starting up of the horse will right the cart, because the thills are pivoted Cleats a,attached By making the tail-board or the tail-board and seat permanent parts of the structure in themanner set forth, much time heretofore spent in handling and hunting these parts when separate or detachable is obviously saved, andthe implement is rendered far more convenient and desirable.

It is to be understood that the term thills includes apole or any other part of the vehicle, which maintains its position while the dumping part is tilted, and by attachment with which the tail-board is upheld, through the medium of the bars E or their equivalent.

I claim as my invention 1. The combination, with the thills and the tilting body, of side bars pivoted between their ends to the body, and connected at their rear ends with the'thills, and a tail-board rigidly attached to the rear ends of said side bars, whereby the tail-board is lifted as the body is dumped, substantially as described.

2. The combination, with the thills and the tiltingbody, of side bars pivoted between their ends to the body, a tail-board rigidly attached to the rear ends of said side bars, and links connecting the front ends of said side bars with the thills, substantially as described.

3. The combination, with the thills and tilt ing body, of side bars pivoted between their ends to the sides of the body, a tail-board rigidly attached to the rear ends of said side bars, and links connecting the front ends of said side bars with the thills, said side bars being pivoted to the sides of the wagon at or near the upper edges of the latter, whereby the tail'board may be arranged at right angles to the bottom of the body, substantially as described.

4. The combination,'with the side-boards and front end-board of awagon, of a seat constructed to fold upwardly, so as to form an upward extension of the end-board, said seat being hinged on the level of the side-boards and made long enough to rest upon the latter when the seat is in a horizontal position, and a stop or stops adapted to limit the forward movement of and to support the said seat when the latter is thrown upwardly into position to form an extension of the end-board, substantially as described.

In testimony that I claim the foregoing as my invention I affix my signature in presence of two witnesses.

MARTIN CONRAD.
