Demanded 4 April 1928, to 14m (Patent application deposited in Belgium 4 April 1937.-Declaration the applicant.) The present invention relates to mounted- electric charge of the type called "mounted-balls" or "cell-balls" or the like. It creates an elevator in the- 5 which the platform is made pumphandle, for the automatic unloading of the load, the switch or controlling in- be, to a determined threshold tilt, or the- [...] Opening the circuit to stop the The platform is made rocker with the means of a counterweight sliding along a vertical guide and being lockable in its upstroke by a stop which- i5 concha. The usual rising portion com- carries a plate which, normally horizontal, may pivot about its axis to reach an oblique position sufficient, for obtain the automatic failover the 90 load. Said tilting is controlled by the counterweight above by means of a cable or any other means. The cable, connected hand to the tray, drives on the other hand, after have passed over a turn roller attached to 9 5 the upright portion, the counterweight sliding above. When the platform reaches the degree desired tilt, for example 45 °, it interrupts the passage of electric current supplied to the engine immediately and thus stops- 3o coating the upward movement which, without this stop, breakage proximity to the control members, the fixed part of the rising platform continuing to mounting and the tilting part is stopped by the counterweight. Celt power interruption is produced by a switch attached to the upright portion, which were driven and automatically by the rocking member at the time the maximum tilting has been reached. On the other hand, the descent of the rising portion and replacement in a horizontal position of the flip part [...] have the effect of this switch and therefore return the running engine. In this case, it is observed that the motor is engaged with the winch mechanism by means of a clutch that at any time of lifting, that the lowering is independent of the stop or the engine is running, and that therefore the operation of [...] indicated above can be performed at the time of the descent of the platform. The attached figure example a schematic of the improved apparatus which can be fixed or mounted on running gear any; The platform uplink consists of a part A remaining always horizontally and a section B pivotable about an axis carried by the part A G.

A cable is tipped or inverted E is fixed, firstly to the end portion of the 5 opposite pivot axis B C, and on the other hand, to a counterweight G that slides along vertical guides.

F A a given time, the counterweight is stopped by the stopper H and the platform, continuing to mounting, the portion B will thus be forced to change to the position indicated in-dotted, No. When the switch reaches a desired angle, for example 45 °, sufficient to cause the automatic unloading, the current is cut by the drop out J which one part is fixed to the part A and the other to the part B. The mounted the 5 platform is interrupted. SUMMARY. Monte-electric charge characterized in that the platform includes a portion remaining always horizontal, which supports the shaft 3o of tilt of a other part, normally horizontal, but is capable of being tilted, to operate automatically unloading as soon as a counterweight, suspended from a cable attached to the pivotable part of the [...] shape and bypassing a turn roller carried by a projection of the platform, strikes against an adjustable stop in position along the vertical [...] of the apparatus, the tilting of the platform having 4o effect for cutting the motor current " as soon as the fulcrum reaches an amplitude determined. - MULLER M..
