SPECIFICATION nforming part of Letters Patent No. I786,926, dated April 11, 1905.

Application filed November 11, 1904. Serial No. 232,380.

To all whom t may con/cern:

Be it known that we, CHARLES H. WELLMAN and JOHN WRIGHT SEAVER, residents of Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented certain new and useful Improvements in Lorries or Dumping-Cars; and We do hereby declare the following to be a full, clear, and exact description of the invention, such as' will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates toan improved lorry or dumping-car, the object of the invention being to provide the lorry or car with improved means for removing material from a bin or bins and filling the car, and thereby cheapening the construction of the bins, as it dispenses' with the usual ore-gates or other feeding apparatus attached to the bin; and with this and other objects in view the invention consists in certain novel features of construction and combinations and arrangements of-parts, as will be more fully hereinafter described, and pointed out in the claims.

. In the accompanying drawings, Figure l is a View in side elevation illustrating our improvements. Fig. 2 is a View in side elevation of the gearing on the car. Fig. 3 is an end elevation. Fig. 4 is atop plan view, and Fig. 5 is a diagrammatic plan view.

The lorry consists of a platform-frame A, supporting a tank or hopper B and mounted on wheels 1, adapted to run on a track 2. The hopper B is supported by means of scalelevers, so that the contents thereof may be weighed.

D represents an electric motor connected by a train of gearing C with one of the caraxles and by beveled gears E with a vertical shaft F. On the upper end of this shaft F apair of curved arms or blades Cr are secured I this construction permits the shaft F and blades G to be moved laterally of the car out of the way of a bin, as shown in dotted lines in Figs. 3 and '4, and also enables the blades to be disposed as far to one side as may be desirable to remove the material from a bin or bins.

The bin or bins I are formed with an inclined bottom, so arranged that the contents of the bin flow down by gravity toward the front of the bin. Extending along the front of the bin is acontinuous slot or opening J, and immediately beneath the same is a horizontal platform or shelf K. The ore slides down the inclined bottom and out on this shelf K as far as the angle of repose.

The operation of our improvements is as follows: The operator stands in a suitable cab L at one end of the lorry or car, and the motor D under his control is started to propel the Ycar alongthe track to a position in front of a bin I. The shaft F and blades G, carried thereby, are then moved to one side of the car to aposition to project the blades over the shelf K. The motor D is then operated to drive shaft F and turn the blades G, which latter will force the material from shelf K down into the hopper or receptacle B, and this operation is continued until the desired quantity of material is received in the hopper B. The material can be weighed as it enters the hopper by the scale-levers, and when the desired amount is received the car can be moved to another bin for different material if a mixed charge is desired. When the proper quantity of material is received in the hopper, the shaft F and blades Gr are moved to the opposite side of the car or out of the way of the bins and the car propelled by its motor Dto the desired point of discharge.

A great many slight changes might be made in the general form and arrangement of the parts described without departing from our invention, and hence we do not restrict ourselves to the precise details set forth, but consider ourselves at liberty to' make such slight changes and alterations as fairly fall within the spirit and scope of our invention.

Having fully described our invention, what We claim as new, and desire to secure by Letters Patent, is-

1. The combination of a lorry or ear, and a rotary device at the top thereof adapted to force material into the car.

2. The combination of a lorry or car, a vertical shaft on the car, means for turning said shaft, and horizontal arms or blades on the shaft adapted to force material into the lorry or car when the shaft is turned.

3. The combination of a lorry or car, a motor thereon, a vertical shaft on the car controlled by the motor, and horizontal arms or blades on the shaft adapted to force material into the ear when the shaft is turned.

4. The combination of a lorry or car, a motor thereon adapted to propel the car, a vertical shaft on the car also operated by the motor, and horizontal arms or blades on the shaft adapted when the shaft is turned, to force material into the car.

5. The combination of a lorry or car, a laterally-movable shaft on the car, and blades or arms carried by the shaft and adapted to force material into the car when the shaft is turned.

6. *The combination with a bin having an inclined bottom and an opening` in its front, and a shelf in advance of the opening` onto which material from the bin moves by gravity, of a lorry or car, and blades or arms carried by the lorry or car and means for moving` the blades or arms in a horizontal plane to scrape material from the shelf into the car.

7. rIhe combination with a frame supported on Wheels, of a hopper carried by the frame, laterally-sliding boxes on the frame,a vertical shaft supported in said boxes, horizontal arms or blades carried by the shaft and adapted to force material into the hopper when the shaft is turned, means for turning said shaft yet permitting the shaft and blades to be adjusted laterally of the lorry or car to dispose the blades in reach of or out of reach of material to be fed to the hopper.

In testimony whereof we have signed this specification in the presence of two subscribing' witnesses.
