WAREHOUSE-TRUCK.

SPECIFICATION formingpart of Letters Patent No. 771,804, dated October 11, 1904.

Application filed April 18, 1904. Serial No. 203,608- (No model.)

To all whom it may concern:

Be it known that I, AUGUST E. R. BLoM UIs'r, a citizen of the United States, residing at Cleveland, in the county of Ouyahoga and State of Ohio, have invented certain new and useful Improvements in arehouse-Trucks; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in warehouse-trucks adapted to convey boxes, barrels, and other bulky freight from one place to another; and the object of the invention is to provide atruck which is adapted to mechanically raise the freight loaded thereon to such higher elevation in or through the truck as may be desired, so that the freight may be unloaded upon a higher plane than that from which it was taken, all substantially asshown and described, and more particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a perspective front elevation of my new and improved truck; and Fig. 2 is a longitudinal sectional elevation thereof, showing the lifting mechanism engaged upon a cask or barrel.

A represents the main frame of the truck, which may be substantially similar to warehouse-trucks ordinarily, and O is a carrier for the freight slidably engaged in slots, grooves, or channels a in the sides of the said main frame. The carrier O is of the skeleton pattern, as here shown, and preferably of cast metal of the requisite size, but which may also be made of any other metal or material that will suit the purpose, and is provided with ribs or projections 0 at its sides adapted to slide in said grooves or channels a and to be raised in respect to the said main frame according to the elevation at which a piece of freight is to be discharged from the truck. Upon the bottom of the said carrier are hooks c, spaced apart relatively as shown and in position to engage the chime bof a barrel D, as seen in Fig. 2, or the edge of a box, and for which purpose the said carrier O is lowered to make such engagement before the barrel,-box, cask, or other article has been delivered upon the yoke-shaped lift or support B at the bottom of the truck. The said carrier C is more or less concaved or curved out centrally in its middle portion to rest the barrel therein and avoid tendency to roll out at either side, and an adjustable hook g is provided on the upper end of the forked hook-supporting member G, which is pivoted at its two forked extremities or ends in cars or lugs c on the carrier and has a threaded upper extremity g with a lock-nut g or the like thereon over the hook g, whereby the said hook can be raised to a higher or lower point on the said stem g and is adapted to engage a cask, barrel, or other article of larger or, smaller size, the proportions of adjustment accomplished in this respect being clearly seen in Fig. 2. Power is applied to the said carrier O to raise the same with the load thereon by means of a threaded shaft H, having engagement with the upper portion of said carrier O through threaded sleeve 0 thereon and carrying a bevel-gear /L at its upper end outside the cross-bar a of the main frame A, in which said shaft is supported. A pinion a on ashort transverse shaft N, through the side of frame A, engages the gear and is adapted to be operated by a hand-crank J, which serves to apply power to the said shaft H and by the rotation thereof causes the carrier O to be lifted more or less, as may be required.

A swinging and practically free brace M is provided at about the center andbottom of the truck, which serves in one way and another to assist in the handling of the truck and freight thereon,and especially serves to steady or support the truck, as seen in Fig. 2, when the carrier is being raised with the load thereon.

By the means thus shown and described I am enabled to lift a piece of freight from the floor and deposit the same upon a platform or other elevated position a foot or more above the floor-level with no more expenditure of strength than is expended through crank J, and this is very slight compared with the weight lifted.

What I claim is- 1. A warehouse-truck having a slidable carrier confined within its sides and provided with fixed hooks at its bottom and aswinging threaded arm at its top and a hook adjustable on said arm to engage the freight, and means to raise and lower the said carrier in respect to the frame, substantially as described.

2. A warehouse-truck having guideways at its sides and a carrier slidable thereon, said carrier having rigid hooks at its bottom to support the freight and a pivotally-supported adjustable hook at its top to engage the top of the freight, and mechanism to raise said carrier with the freight thereon, substantially as described.

3. A warehouse-truck having guideways in its sides, a carrier for freight slidably supported in said guideways and provided with supports at its bottom to carry the freight, and means at the top of said carrier adapted to engage the freight at its upper portion, said means comprising a forked hook-support pivoted on said carrier and a hook at right on said carrier to secure a piece of freight thereon, substantially as described.

In testimony whereof I sign this specification in the presence of two witnesses.
