Gottlob Schöller in Rastatt, Baden. Box dump truck.

Patented in the German Empire on January 1, 1924.

With the now usual retrieval of the tilted box, this process involves many Inconvenience, loss of time and a great deal of labor. the. The raised box is awkward to hold. It must be in the designated bracket Timbers are tucked in, around these in turn because of the height because of ropes, and then pull the team from an unfavorable point of view for this purpose a.us returned the box with great effort and loss of time.

The present invention completely avoids these inconveniences by providing for Box tipping no special tipping team is necessary, but either the train attendant (brakeman) or the track-laying team, two to three men, are completely sufficient to empty the train, since the retrieval and locking of the

tipped box takes place completely automatically by the pulling movement and emptying of the train takes place in barely half of the previous time.

In Fig. Ι of the drawing, box prepared for tilting (the locking hook e released ), and Fig. 2, box tilted, this process is shown.

On the protruding end of the running axles there is a simple coupling σ with a drum, which is actuated by levers b and c attached to a shaft. The cam on the bolt holds the coupling in the disengaged state (Fig. I).

If the box is to be tilted, the locking hooks e located at the ends are knocked upwards until they rest on the movable tongue Z of the lever g on the through shaft / seated.

ao The tilted box strikes back the bolt d and the lever c is free, whereupon the coupling is switched on by means of a spring or weight as soon as the claws fit together. At the same time, an am

S5 latch d located stop h the angle lever i, which is also fastened on the shaft f , and the lever g up, so that the locking hooks e fall back into their original position (Fig. 2). A locking hook k , which rises when the box is opened, allows the load to slide off through the opened flap.

If the empty train is now transported back to the filling station, the pulling element m wraps itself around the drum and pulls the box back into the horizontal position, with the same pressing down the angle lever,

which pushes the bolt d forward again and releases the coupling. The locking hooks e held in the closed position by weight hold the box in place.

The retrieval of the box can be done from Leiden axes, with the difference when switching on the two couplings by appropriately strong springs, which are attached to the end of the tension elements are compensated, or by a back gear driven by the axles.

To support the lifting of the tipped box, on the tilting side Springs are installed. 5 »

The force required for tilting can be achieved by arranging the pivot point accordingly be reduced so that at most two men are sufficient instead of the previous ones Tipper column from 12 to 16 men.

Claims (1)

Patent claim: Box tipping car with automatic erecting device acting through the forward movement of the car, characterized in that the tipped box automatically switches on a coupling (α) with winch, which is known per se, is mounted on the running axles or on a special back gear driven by the axles, which when moving the empty car pulls the box back into the horizontal position, the coupling automatically switched off by the bolt (d) and the box is held in a known manner by self-acting locking hooks.
