WAGON-DUMP AND ELEVATOR.

SPECIFICATION forming part of Letters Patent N 0. 449,680, dated April 7, 1891. Application filed August 81, 1888. Renewed August 20, 1889. Again renewed August 11, 1890. Serial No. 361,639- (No model.)

To all whom it may concern:

Be it known that I, JOHN S. KIDD, acitizen of the United States of America, and a resident of Des Moines, in the county of Polk and State of Iowa, have invented an Improved VVagon-Dump and Elevator, of which the following is a specification.

My invention consists in the construction and combination of a dumping-platform, an elevator-frame, an elevator-box, and mechanism for operating the platform and raising and lowering the elevator, as hereinafter set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which Figure 1 is a side view of the complete machine, showing the elevator-box suspended and a hinged section of the platform adjust- -ed as required to allow the box to descend to the ground. ,Fig. 2 is a top view of the platform and the operative devices combined with the platform. Fig. 3 is an enlarged side view of a section of the dumping-platform and operative mechanism combined therewith. Fig. 4 is a top view of the top portion of the elevator-frame, and Fig. 5 is an end view of the same frame. Fig. 6 is a top view of the frame upon which the elevator-box is operated, and Fig. '7 is a side view showing the box upon said frame.

A are the sills of the elevator-frame.

A are extensions hinged to the ends of the sills in such a manner that they can be turned upward, so that the complete sills may be used as runners for moving the frame and complete machine from one place to another.

A are posts fixed to the ends of the sills A.

A represents the platform-frame fixed to the sills A. C

A are cross-pieces fixed to the tops of the posts A A are braces that extend from said crosspieces to the platform-frame, and A are braces that extend from the same cross-pieces to the posts A B is a section of the platform, connected with the frame A in such a manner that it can be tilted as required to dump a load from a wagon resting thereon.

faster and a greater distance, and the rear end of the section and wagon will descend, and consequently the dumping-platform can be lower, than when the tilting section has a stationary pivot.

O is a hinged and reversible section of the tilting platform B at its rear end.

C is a wheel-scotching block or bar fixed on its top in such a manner that it will restrict the backward motion of a wagon and prevent the wagon-wheels from running off the tilting section when the section is inclined as required to dump the contents of the wagon into the elevator-box.

d are iron bars fixed on top of the section 0 to extend outward in such a manner that when said hinged section is inverted, as indicated by dotted lines in Fig. 3, they will project under a fixed incline O and aid in uniting the two parts to produce a bridge over which a loaded wagon can be advanced to the top of the tilting section.

0 is a frame hinged to the ends of the sillextensions A and O is a fixed floor that connects with the sections 0 and 0 when the frame is lowered to produce a complete inclined plane over which a wagon can be advanced from the ground to the top of. the tilting platform-section O.

F is the-frame that supports the elevatorbox. It is suspended from the top of the elevator-frame by means of four ropes F that pass over pulleys F attached to the crosspieces A at the top of the frame at four different points, as shown in Fig. 4.

F are triplegrooved directingpulleys, over which the ropes F are passed downward and connected with chains H, (by tying or in any suitable way,) which chains are extended over sprocket-wheels and connected with cables that are passed over the triple-grooved pulleys F and fastened to the platform.

II are wire ropes connected with the ends of the chains to produce endless flexible devices that will be operated by means of sprocket-wheels in such a manner that the rope portions will be constantly on the pulleys F", while the chains are constantly on the sprocket-wheels H 3y thus combining the ropes F and 11' with the chains H comparativcl y short pieces of chains and shorter ropes are required and the cost of construction of the complete hoisting mechanism reduced, while i s efficiency is improved.

1? are sprocket-wheels fixed to an axle H that has its bearings fixed to the frame A in such a manner that when the axle is rotated the ropes l? on the pulleys F will be lengthened or shortened, as required, to raise or lowenthe frame F.

J is a drum fixed to the axle H J is a rope fixed to the drum J and extended over a directing-pulleyJ attached to the frame A in such a manner that when a horse is hitched to the end of the rope, or other power applied to pull on the rope, it will rotate the drum and the two sprocket-wheels II as required to operate the chains 11 and ropes F and thereby elevate the frame F and a loaded box upon the frame.

L is an elevator-box supported upon the frame F. The central portion of its bottom is flat and the end portionsinclined.

m are metal rockers, fiat-bottomed and straight at their central portions and curved and toothed at their end portions, fixed to the outside faces and centers of the box.

m are straight or curved metal bars or racks fixed to the side pieces ofthe frameFin such a manner that the metal rockers m will rest level thereon and support the box level, but allow it to be tilted and its contents emptied from either one of its ends by means of ropes m", attached to the ends of the box. 13y thus making the central portions of the rockers straight the loaded box will remain stationary and balanced in. its normal condition, so

that a locking device for retaining it stationary upon its movable support is not required.

m' are ropes detachably connected with the frame F and hinged end-gates at the ends of the box in such a manner that they can be readily adjusted as required to keep one end closed while the box is being tilted and the other end opened at the same time.

n is a shaft in bearings fixed to the frame A. It has fixed drums n, to which ropes n" are attached and extended upward and over pulleys n and then down and fastened to the tilting section B of the platform in such a manner that the front end of the tilting section can be lifted by rotating the shaft by means of a crank-handle on its end.

'2' is a ratchet-wheel fixed to the shaft 22, and

'1" is a pawl pivoted to the frame A in such a manner that the shaftcan be locked,as required, to retain the tilting section and a wagon thereon elevated at their front ends as long as may be necessary to allow the contents ot'the wagon to be discharged into the elevatorbox when it is resting upon the ground at the rear end of the platform and wagon.
