WAGON-DUMP AND ELEVATOR.

SPECIPICATIONforming part of Letters Patent No. 361,297, dated April 19, 1887.

Application filed August 2, 1886.

To all whom it may concern.-

Be' it known that I, JOHN S. KIDD, a citizen of the United States of America, and a resident of Des Moines, in the county of Polk and State of Iowa, have invented new and useful Improvements in Wagon -Dump and Elevator, of which the following is a specification.

My invention relates to the apparatus shown and described in my application N o. 202,219, filed May 14-, 1886; and my object is, first, to dispense with the winch, so that the elevatorbox can ascend partly through the top of the elevator-frame and the height of the frame reduced; second, to restrict. the motion of the elevator-box when it is tilted to discharge its contents; third, to open the hinged end-gate of the elevator-box gradually, as required to prevent too sudden a discharge from the box; fourth, to prevent jarring and concussion in raising and lowering the elevator-box, and to reduce the cost of the hoisting mechanism.

I accomplish the results contemplated 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 elevator-frame and a section of the Wagon-dumping platform and an end of the elevator-box suspended in the frame. Fig. 2 is a side view of the elevator-frame and suspended elevator-box, taken at right angles relative to Fig. 1. Fig. 3 is an enlarged side view of a top section of the elevator-frame, the elevator-box, and operative devices attached thereto. Fig. 4 is a top 'view of the elevator-frame, the elevator suspended therein, and operative devices combined with the frame and box.

A are the corner-posts, and A the parallel base pieces and runners of the portable elevator-frame.

A represents the wagon-dumping platform, and A the hinged section, which when lowered forms an'inclined plane, and is elevated when required to allow the elevator to be lowered when the loaded wagon is in position upon the platform to dump its load into the elevator-box. 7

A are metal corner-pieces fixed to the elevator-frame to brace and strengthen it.

A are re-enforcing strips and guides fixedto the corner-posts A.

Serial No. 209,762. (No model.)

B B are parallel sliding bars fitted between the guides A on the posts A, as clearly shown in Fig. 4, in such a manner that they will readily slide up and down in the elevatorframe. Shoulders on their ends and clasps,B, fixed thereto prevent the bars from lateral motion.

O are the sides, and G the bottom, of an elevator-box fixed to an axle, O,that has journals on its ends resting in bearing 0*, fixed to the bars B, as clearly shown in Figs. 2 and 3. The box is thus pivoted at its center and balanced upon the axle and the parallel bars in such a manner that it can be raised and lowered with the bars and tilted to discharge its contents from either end..

The bars B and box 0 C are jointly suspended and balanced in the frame by means of wire ropes Nos. 1 2 3 4, attached to the end portions of the bars and passed upward over directing-pulleys 0, attached to the Ol0SS- pieces at the top of the frame, and from thence over pulleys d and d at the corners and on the top of the frame, and then down over a pulley, d, fixed to the top and side of one of the postsA and fastened to a movable pulley, d.

d is a pulley in a bearing fixed to the base of theframe.

No. 5 is ahoisting-rope fastened to the same base at the side of the pulley d and doubled over the pulleys d and d two or more times in such a manner that when power is applied to the end of the rope No. 5 it will draw the movable pulley d' downward and the elevator-box suspended by the ropes 1 2 3 4 upward. Weights may be combined with this movable pulley to balance the weight of the elevator.

f is an eccentric brake-bar pivoted to the base of the frame by means of a bearing, f, in such a manner that it will engage the hoisting-rope No. 5 and hold it fast at any point desired, as required to retain the elevator-box stationary at any point of elevation, and also as required to prevent any backward motion of the rope and falling of the elevator-box.

f is a pulley attached to the base of the frame to direct the rope straight forward from the eccentric f and fixed pulley d. Additional directing-pulleys may be applied to di root the hoisting-rope at any angle or direc tion relative to the frame.

g are wings fixed to the ends of gates hinged at their bottom edges to the bottoms and ends of the elevator-box in a manner common to end-gates in wagon-boxes.

g are pulleys in bearings y, fixed to the sides G of the box in inclined positions.

9 are stops, preferably formed integral with the bearings g, that project outward to engage the top surfaces of the bars B when the elevator-box is tilted, as shown in Fig. 3, and as required to restrict the revolving motion of the elevator-box that is pivoted to those suspended parallel bars.

9 are ropes fastened to the wings g of the hinged end-gates and detachably connected, one with the bar 13 and the other with the side 0 of the box, as clearly shown in Fig. 3, in such a manner that when the end-gate is unlatched and the elevator-box begins to tilt one of the hinged end-gates will be allowed to open downward gradually as the ropes 9 slip over the pulleys 9 until the stops 9 come in contact with the bars B to arrestthe tilting motion of the elevator-box, and also the motion of the hinged end-gate.

h are elbow-shaped levers that have hooks h on their ends, pivoted to the opposite sides and ends of the bottom of the elevator-box in such a manner that they will engage fixed pins h, that project laterally from the inside faces of the suspended bars B, as required to latch or look the box to the bars and to secure the closed end-gate to the box by means of the ropes g.

h are fixed pins that project laterally from the posts A in such a manner that the long arms of the levers h will come in contact therewith to be depressed thereby as the elevatorbox ascends to disengage the hooks h from the pins h to arrest the ascent of the end of the box and open the end-gate.

is a fixed pin projecting laterally from the post A. Both the pins h and h are formed on or fixed to plates J,that are detachably fastened to the posts A by means of screws, or in any suitable way, so that they can be raised or lowered, as required, to tilt and empty the elevator-box at any point of elevation desired.

at are metal bars, of double-elbow shape at their rear ends, fixed against the sides 0 of the elevator-box near their top corners, to project horizontally beyond the ends of the boxjust far enough to allow them to pass upward without coming in contact with the pins h. \Vhen they have passed above the said pins and the lever h is tripped by coming in contact with the pin h, as required, to open the end-gate, the ascent of the open end of the box will be arrested by the lever h and pins h, while the bars B continue to rise and the metal bars on slide outward over the pins h and aid in supporting the arrested end of the loaded box and preventing it from any sudden motion while being tilted and emptied and when the box is empty and the power applied to the hoisting-rope relaxed the parallel bars B and theelevatcd end of the box will desccnd,while the open end will be supported by means of the bars at and pins h' until the box has resumed its normal horizontal and balanced position; and as the parallel bars B are thus lowered and the open end of the box remains stationary, the ropes 9', attached to the bars 13, will be drawn over the pulleys g, as re quired, to automatically close the hinged open end-gate, and the pointed hooks h will slip upward past the fixed pins h, as required, to engage the pins, and thereby automatically lock the box to the bars 13 and secure the endgate at the same instant that it is closed.

In the practical use of my improved box elevating and dumping mechanism a loaded wagon is placed upon the dumping-platform and its contents emptied into the elevator-box, and the hoisting-rope then fastened to therear axle of the wagon by means of a hook, or in any suitable way, and the wagon then advanced and moved away to lift the elevatorbox by means of the ropes and pulleys used in place of the winch, heretofore.

N (shown in Fig. 1) represents my adj ustable chute, that can be raised and lowered relative to the car, crib, or building into which the contents of loaded wagons are to be placed by means of my elevating and dumping mechanism.

To tilt the elevator-box in the opposite direction from that shown, I simply detach the one pair of ropes 5 from the sides of the elevator-box and attach them to the parallel bars B, and detach the other pair from the opposite ends of the same bars and attach them to the box, and shift the plate J to the opposite side of the frame.

From the foregoing description of the construction of the parts the practical operation and utility of the complete invention will be obvious to all persons familiar with elevators and dumps.

I am aware that a frame has been suspended in an elevator-frame by means of ropes, and an elevator-box pivoted in the suspended frame in such a manner that the box could be tilted and dumped in one direction only; but combining a box with two parallel bars in such a manner that the box can be tilted in opposite directions and its contents dumped on opposite sides of the elevator-frame at pleasure is novel and greatly advantageous.

I am also aware that a cage having a pivoted platform has been suspended in a frame and provided with guides and stop devices in such a manner that a car placed upon the pivoted platform in the bottom of the cage could be tilted in one direction only; but my manner of combining a box having hinged endgates with two parallel and independentlysnspended bars in an elevator is novel,and enables me to discharge the contents of the box from either end thereof at pleasure.

I claim as my invention 1. The bars B, independently suspended in the frame, and provided with shoulders on ICO their ends and clasps B and bearings O, the elevator-box O having hinged gates at its ends, and a fixed axle, O in combination with an elevator-frame having fixed guides A,substantially as shown and described, for the purposes stated.

2. The combination of the elevator-box, the elevator-frame having the fixed pulleys G (l d d, the loose pulley d, and the

hoistingropes

3. The combination of an elevator-box, an elevator-frame having a pulley in a vertical position at each of its top corners, pulleys in a horizontal position at two of the top corners, a pulley at the side of one of the top corners, and four hoisting-ropes attached to the base of the frame, all adapted to operate as set forth.

4. The combination of the elevator-box, an elevator-frame having fixed pulleys C d d d, the movable pulley d, the hoisting-ropes 1 2 3 4, a fixed pulley, 01, and a hoisting-rope, 5, all adapted to operate as setforth.

5. The combination of the parallel bars having hoisting-ropes connected thereto, an elevator-box pivoted at its center to the bars and having a hinged end-gate, pulleys fixed to the sides of the elevator-box, and adjustingropes over said pulleys, and connected at one end to the hinged end-gates and at the other end to the elevator-box, all substantially as described.
