Application filed. February 3, 1926. Serial No. 85,665

The present invention relates to conveyers, particularly such as the trucks employed 1n factories for carrying loads thereabout and discharging the same at intervals in their travel; and the object of the invention is,

generally, to provide a Vehicle of that character improved in various respects hereinafter appearing; and more particularly, to provide such a vehicle having means for travelling and'for loading and unloading the same, operated from a single source of power.

This and any other objects hereinafter appearing are attained by, and the invention finds preferable embodiment in, the organization hereinafter particularly described in the body of this specification and illustrated by the accompanying drawings, in which Figure 1 is a top plan View of a loadcarrying vehicle, the platform thereof being broken away to disclose the working parts thereunder Figure 2 is a longitudinal sectional view thereof taken on a vertical plane corresponding to line 2-2 of Figure 1;

Figure 3 is a transverse sectional View of certain parts of the same taken on a vertical plane corresponding to line 3-3 of Figures 1 and 2;

' Figure 4 is a front elevation of driving means for operating said vehicle and connections therebetween; and

Figure 5 is a side elevation of the same.

In the embodiment of the invention illustrated by the drawings, a load-conveyer, the vehicle 1, travels on its wheels 2 along a track 3, and comprises frame work 4 supporting a platform 5 on which is carried the load. The vehicle is moved along the track by an endless cable 6 which is travelled by suitable means or power, as the electric motor indicated at 7 whose shaft has a worm 8 meshing with a worm wheel 9 whose shaft carries a drum 10. As shown, this endless cable is carried in the grooves 11 of the drum 10, the grooves 12 of the rotatable idler drum 13, and by the sheaves 14, 15, 16, the cable-tightening sheave 17 (having the weight 18), and the sheave 19 mounted on the floor 20 at a suitable distance beyond that end of the vehicle which is opposite to the motor. This cable is wound on a pair of rotatable elements, the drums 21, 22 mounted adjacent one side of the vehicle, the opposite side of the cable being wound on a pair of rotatable elements, the drums 23, 24 mounted adjacent the vehicles opposite side. When the brakes 25 are applied, through their operating lever 26 and connecting rod 27 to the elements or drums 21, 22 the frictional engagement of the moving cable therewith moves the vehicle in one direction; while the cable moving in the same direction moves the vehicle in its opposite direction when the brakes 28 are applied, through their operating lever 29 and con necting rod 30 to the elements or drums 23, 24. These drums or elements 22, 23 and 24 freely rotate on their carrying shafts 40, 41 but the element or drum 21 is keyed to its shaft which carries a gear 32 meshing with the gear 33 on the short shaft 34 adapt-' ed to be coupled as by the conical clutch 35 with a rotatable element, the drum 36' mounted on the vehicle, on which drum a cable 37 is wound. When the brakes 25, 28 are released, the moving cable 6 rotates the element or drum 21 and thereby the drum or element 36 so that the cable 37 is drawn to move a load, to which it is attached as by its hook 38, to or from the vehicle and from or to a stationary platform 39 on either side of the vehicle, the vehicle itself being held against movement on its track by brakes 42 applied to its wheels 2 by a pedal lever 43 having the connecting rod 44 extending therefrom to the crank arm 45 of the brake-operating shaft 46.

A sheave 47, around which the cable 37 may be passed when used to draw the load from the vehicle, may be applied to any one of the spindles 48 on the posts 49 located adjacent the vehicles sides and spaced at convenient distances apart.

It will be seen that the provision of the pairs of drums or elements 21, 22 and 23, 24, instead of the single elements or drums 21 and 23, serves to increase the friction of the cable 6 when said elements or drums are braked to move the vehicle along its track.

The clutch 35 is operated by the lever 50, connecting rod 51 and clutch-fork 52.

It will be seen that the vehicle may be moved slowly or started from a stationary position slowly by applying the brake 25 or the brake 28 with slight force, although the cable is travelling at constant speed; and that the speed of the vehicle may be increased by applying the brake with greater force; and that when the brake is applied with suflicient force to hold the rotatable element engaged thereby against rotation, the vehicle moves at the same speed at which the cable is travelling.

The invention being intended to be pointed out in the claims, is not to be limited to or by details of construction of the particular embodiment thereof illustrated by the drawings or hereinbefore described.

What is claimed is:

1. In an organization of the character described: a load-carrying vehicle; a rotatable element mounted thereon; a second rotatable element mounted on the vehicle; releasable means for rotating said second element by said first-mentionedelement; means for holding said first-mentioned element against rotation; a cable .Wound on said first-mentioned element; means for travelling the cable; means actuated by the rotation of said second-mentioned element for moving a load relatively to the vehicle.

2. In an organization of the character described: a load-carrying vehicle; a rotatable element mounted thereon a second rotatable element mounted on the vehicle; releasable means for rotating said second element by said first-mentioned element; means for holding said first-mentioned element against rotation; a cable wound on said firstmentioned element; means for travelling the cable; means actuated by the rotation of said second-mentioned element for moving a load relatively to the vehicle; means for holding the Vehicle against movement.

3. In an organization of the character described: a load-carrying vehicle; a rotatable element mounted thereon; a second rotatable element mounted on the vehicle; releasable means for rotating said second element by said first-mentioned element; means for holding said first-mentioned element against rotation; a cable Wound on said first-mentioned element; means for travelling the cable; a cable wound on said second-mentioned element for drawing a load relatively to the vehicle.

I. In an organization of the character described: a load-carrying vehicle; a rotatable element mounted thereon; a second rotatable element mounted on the vehicle; releasable means for rotating said second element by said first-mentioned element; means for holding said first-mentioned clement against rotation; a cable wound on said first-mentioned element; means for travelling the cable; a cable wound on said second-mentioned element for drawing a load relatively to the vehicle; a sheave rotatably mounted extraneously the vehicle and adapted tocarry the second-mentioned cable.
