GEORGE R. ORAMER, OF CINCINNATI, OHIO.
IMPROVEMENT IN DUMPlNG-WAGONS.
Specification forming part of Letters Patent No. 62,478, dated February 26, 1867.-
To all whom it may concern.'
Be it known that I, GEORGE R. CRAMER, of Cincinnati, Hamilton county, and State of Ohio, have invented a new and useful Improvement in Dump-WagonsJ of which the following is a full and clear description thereof, reference being had. to the accompanying drawing, making part of this specification.
My improvement relates to a device for elevating the front end of the wagon-body to such a height that its weight, overcoming the friction of the rollers upon which it rests, causes it to recede backward until the center of gravity of the load in the wagon-body shall have passed beyond the rear ends of the side rails of the frame of the wagon, when the tail end of the wagon-body descends to the ground.
Figure l represents a longitudinal section of my improved wagon, showing the device for dumping in operation. Fig. 2 is an elevation of the front end of the wagon, the forward carriage being removed.
A is the bolster` upon the front axle. B is the rear axle. "lo the bolster A and axle B are secured the side rails C, the rear ends of which project a little beyond the rear axle B. A rod, a, extends between and is secured to the side rails C. The rod a carries two friction-rollers, b, one near each of the side rails C. The rollers are in contact with the bottom of the wagon-body. Guard-straps c pass over the rod a, and are firmly secured at either end to the under side of the wagonbody. To the rear of the front carriage is located the crankshaft, D journaled in one of the side rails O, and, passing. through the opposite rail, terminates in the lever d. The crankshaft D is crank-shaped at e, and carries a loose guttered roller E. The roller is located at an equal distance from each side rail C. A ridge, f, corresponding in contour to the depression in the roller E, is made fast to the under side of the wagon-body. It extends from the front of the wagon-body to a point in the rear of the crank-shaft D. The wagonlbody F rests upon the frame ofthe wagon of which the side rails C make part. The diameter of the guttered roller E, in connection with the location of the crankshaft bearings, is such that no weight of the wagon-body shall rest upon it. The crank-shaft D is located at such a distance to the rear of the front end of the wagon that the guttered roller E shall be to the rear of the front end of the wagon-body F when the wagon-body is rotating. about the frictionrollers b.
The operation of dumping a load is performed in the following manner The lever d is rotated in the arc of a circle till it attains the position indicated in the accompanying' drawings. The guttered roller E is caused to press upon the ridge f on the under side of the wagon-body, which it elevates. As soon as a sufficient inclination of the wagon-body F is attained, where the weight of the load is sufficient to overcome the friction of the rollers, the wagon-body F is rolled backward until the center of gravity ofthe load in the wagon-body F has passed to the rear of the friction-rollers b, when the tail end of the wagon-body F falls to the ground, as indicated by the outline in Fig. 1.
It is obvious from the above description and operation of the wagon that guttered roller E is employed to the same extent in rolling backward the wagon-body as on the frictionrollers b.
What I claim as new, and desire to secure by Letters Patent, is-
The combination of the crank-shaft D, roller E, lever d, and body F, or their equivalents, when the same are arranged and operate sub stantially as above described.
GEO. It. ORAMER.
