METHOD OF LOADlNG AND UNLOADlNG CARS.

SPECIFICATION forte part of Letters Patent No. 325,308, dated September 1, 1885.

Application filed July 22, 1885.

To all whom it may concern.-

Be it known that we, HENRY M. BARNHART and EDWARD HUBER, of Marion, in the county of Marion and State of Ohio, have invented certain new and useful Improvements in Methods of Loading and Unloading Cars; and we do hereby declare the following to beafull, 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.

Ourinvention relates to an improved method of loading and unloading cars, the object of the same being to materially lessen the work of loading and unloading plat-fornrcars with out increasing the cost of the machinery employed for the purpose; and with this end in view our invention consists in the method or process to be hereinafter more fully described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in side elevation showing our inr provement applied to a train of platfornrcars. Fig. 2 is a plan view of the same.

A represents a train of platfornrcars, each of which latter is provided on its opposite side with the upwardly-projecting guide B, which latter can be provided with rollers or not, as desired, and can be removed from the cars when not needed.

0 is a sled or carriage formed of a series of beams or runners, a, connected together by cross-braces a, and provided at one or both ends with the rigid loops D, to which the tackle for sliding the sled from car to car is attached. The sled thus formed is preferably about as wide as the car-platform, and is provided with the beveled ends, as shown, which permit the sled to slide from one car to another without liability of becoming wedged. This sled rests solidly on the platforms, and is provided on its upper surface with a circular track, having a flat upper surface, and a toothed perimeter, on which the crane or den rick frame rests. This frame consists, essentially, of a base, Z2, and a top, 0, connected together by suitable uprights, d, and braces 0.

At one end ofthe base bis pivotally mounted the boom F, the upper end of which is supported by one or more tic-rods, E. This boom is adapted to carry an excavator, F, or block and tackle for elevating and lowering cross- (X0 model.)

ties, rails, and other articles. This excavating or hoisting tackle is operated by the rope or chain G, the inner end of which is secured to the windlass H, mounted in bearings secured to the derriclcframe. Alongside of the windlass H is located the windlass H, to which is secured a rope or chain, by which the sled is moved. The rope or chain passes from the windlass upwardly over a pulley, f, thence downwardly in or nearly in a line with the axis of the derrick-frame, and around the pulley g, secured to the sled, then forwardly to a pulley secured to one of the cars, and then rearwardly to the rigid loop on the end of the sled.

The windlasses are operated by the engine I, which latter takes steam from the boiler,

preferably located on the end of the frame farthest from the derrick. This engine is connected with both windlasses, and the latter are provided with clutch or other mechanism whereby either windlass can be thrown out of engagement with the engine, as necessity demands.

The derrick-frame is pivoted to the sled in a vertical line passing through the center of the circular track, and is provided with rollers, which latter rest on the upper smooth surface of the circular track and form bearings for the derrick-frame. This frame is also provided with pinions, which latter engage the teeth on the perimeter of the circular track,

for the purpose of changing the position of the derricleframe so as to bring the derrick from one side of the car to the other. These pinions can be operated by hand-wheels or by the engine. The derrick can also be turned by the engine, or by suitable devices operated by hand.

By the above arrangement of parts it will be seen that the sled carrying the derrick can be drawn away from the cars as the latter are loaded, and the cars can be drawn toward the material to be loaded. lVhen unloading, the derrick or crane can be drawn toward the cars to be unloaded.

\Vhen the machine is employed for cleaning the side of a track or widening cuts alongside of a railroad track, an ordinary excavator would be employed, and the material as it is excavated would be dumped on the cars.
