APPARATUS FOR UNLOADlNG CARS.

SPECIFICATION forming part of Letters Patent No. 678,634, dated July 16, 1901.

Application filed March 13 1901.

To all whom it may concern.-

Be it known that I, WATSON BATOHELOR, a citizen of the United States, and a resident of the city of New York, borough of lVlanhattan, in the county and State of New York, have invented a new and Improved Apparatus for Unloading Cars, of which the following is a full, clear, and exact description.

This invention relates to an apparatus for unloading cars, and comprises a cradle poised at its middle or approximately its middle and provided at one end with a weight, the parts being arranged so that when a loaded car is run on the cradle the weight of the car will tilt the cradle, causing it to throw the car into an inclined position, whereupon the load of the car may be discharged through the end thereof, and then when the car is unloaded the weight at the end of the cradlewill assert itself to throw the cradle and car back to horizontal position.

The invention may be used in various connections, as will suggest themselves to persons skilled in the art. It is particularly adaptable to unloading freight-cars into vessels, and by this means the cars may be very rapidly and easily unloaded, so that the load will pass from the cars directly into the vessels without additional handling.

This specification is a specific description of one form of the invention, while the claim is a definition of the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in both views.

Figure 1 is a side view of the invention, and Fig. 2 is a section on the line 2 2 of Fig. 1.

a and of represent the stationary track, which is laid on suitable trestle-work b, elevating it in the customary manner. 0 indicates two columns or supports which carry rockably the trunnions d of the cradle d. This cradle is provided with rails 61?, matching with the rails a, and a, so that the freightcar (indicated at e) maybe run from the rails to and a onto and off of the cradle 01, as desired. For holding the car e on the cradle during the tilting operation I provide tie-rods d which may be of any desired construction and which are connected between the car and the cradle, as shown. A sector-barfis attached to the end of the cradle, which is adapted to move downward, as shown in Fig. 1,

and this sector-bar runs through a suitable housing f on the trestle-work (Z, on which housing is carried a hand-screw f or other fastening device. By these devices the cradle may be locked in any position desired. The opposite end of the cradle d is provided with a counterweight g. (Best shown in Fig. 2. The counterweight g comprises a number of blocks, preferably two, of iron, stone, or other weighty material, and these blocks are held by bolts g between the truss-beams or girders forming the framing of the cradle d. Reference to Fig. 2 will show that three of these girders are here illustrated. Obviously any number might be employed and arranged in parallelism, as shown, with the sections of the weight bolted to them.

The operation of the apparatus is as follows: Assuming that the car is provided with means at its end for discharging the load and that the cradle 61 lies in horizontal position, the car should be run onto the cradle from the track at the right-hand side thereof, and when the car reaches a point partly beyond the trunnions cl of the cradle the weight of the loaded car will cause the cradle to tilt into the position shown in the drawings. "The doors of the car may now be opened and the car will dump its load. When the car is thus relieved of its load, the counterweight Q will assert itself and the cradle cl will be thrown back to horizontal position. By operating the screw f the cradle may be released or fastened immovably at will.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- In an apparatus for unloading cars, the combination with a stationary track, of a cradle, a support on which the cradle is pivotally mounted intermediate its ends, weight-blocks fastened between the beams of the cradle at one end thereof, a curved bar fastened to the opposite end of the cradle, a stationary guide in which said bar runs, and means for remov ably holding the bar rigid with the guide.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

WATSON BATGIIELOR.
