WAREHOUSE DUMPING TRUCK.

Applicationfiled February 5, 1921. Serial nu. 44.2mm.

To a ZZ whom it may concern:

Be it known that I, KrNsnY CAnwAnAone a citizen ofthe United States, residing at Argentine, in the county of VVyandotte and State of Kansas, have invented certain new and useful Improvements in Warehouse I DumpingTrucks; and I do declare the following to vbe afull, clear. and exact description of the invention, such as will enable others skilled in the artto which itjappertains to make and use the same, reference be ing had to the accompanying drgnvings and to the figures of reference marked thereon, which form a part of this specification.

This invention relates to barrel'trucks and it is particularly adapted for usein handling open head barrels with ease and dispatch.

While the invention is adapted to handle barrels and 'casks of various form and size, it is primarily intended for use in connection with open ended barrels in' lubricating plants where the open endedbarrel'must be raised and transported to another place.

The specific embodiment of my invention selected for the purpose of illustration shows a novel means forclamping the barrel in the .middle so as to balance the same in turning for the discharge, and I have shown theclamps laterally adjustable for different sized barrels, which are adapted to engage the barrel and lift it from it support.

I have also shown means for supporting the barrel upon a circular frame with handles provided with break joints whereby, the handles may be used for propelling the vehicle or for turning it, as the occasion may demand.

While I have shown with considerable particularity the preferred ,form of my in vention and will describe in detail the manner of construction in operating it, I do not wish to be understood as limiting myself to the particular form shown, but I reserve the right to make such changes in form, proportion and minor details in construction as come within the scope of the following claims and without departing from the spirit of my invention.

In the drawings, Fig. 1 is a perspective view of a truck constructed in accordance with my invention.

Referring now to the drawings by numerals of reference. i

1 designates a semi-circular angle frame on which are suitable wheels or casters? and 3, there being standards or l fastened to the flange of the angle, as best seen in Fig. 1, so that the frame may stand in a hori- Zontal plane when at rest. Upon the semi circular frame 1 and near the respective Fig. 2 1

ends thereof are standards 5 and {twhich receive the arms 12 and 13 of the horizontal sl'idable clamp-actuating yoke 14-, to which is pivoted a connecting membe 15, carrying a clamp connection 16 fODOIlG of the clamps 17 or 18, the connections being such that the clamps may swivel upon the connection 16 and pivot ina horizontal plane by the clamp connection 15so that the clamps are readily adjustable to the barrel whereby the barrel is always supported in a vertical position. The rear ends 19 and 20 of the clamps are connected by a coil spring 21, whereby the forward ends will have a tendency to move apart. The inner edges of the arms 12 and 13 are toothed or serrated as at 22 and 23 to receive the teeth 24 and 25 of the curved clamp actuator 26, which is provided on its back with a dovetail 27 to engage a corresponding groove 28 in the sleeve 8 the curved portion. 29 being adapted to ride in the spaces between the teeth and force the yokes forward so as to cause the clamps to bind against the cask or barrel.

The lower ends of the member 26 are provided with perforate lugs or projections 30, to be engaged by'the end 31 of the lever 32, which is pivoted at 33 to the link 34:, in turn supported on a bracket 35 carried by the flange of the angle frame 1. The upper end of the lever 32 is provided with a slot 36 to be engaged by a bolt 37 in a guide 38 carried LF TO ROY L.

by the 'handle lever 39, pivoted at to the link 34. Therefore, if the bolt is withdrawn from engagement with the slot 36 through the medium of the connection and the manually-operated device 41, the handle may swing down, as shown in Fig. 1.

There are two levers corresponding to 39, the opposite one being designated 39, and these levers are connected by a cross handle 42, the construction of the lever 39 being substantially that of the one designated 39, which is the only one shown in detail.

Carried by the respective arms 39 and 39' are pivoted racks or serrated latches 43 and 44, which are adapted to engage the edges of the keeper loops and 46, carried by the flange of the angle frame 1 so that the sleeve members 8 and 9 may be held in any vertically adjusted position. For example,

suppose the cask or barrel 47 is to be transport-ed by the truck. The truck will be moved into position, as shown in Fig. 1, so

that the clamps 17 and ,18 and the sleevesS and 9 will be in their lowermost positions.

The operator then moves the handle consisting of the members 39, 39, and 42 into the position shown in Fig. 4 and pulls down upon the bar 42 until the latch levers 43 and 44 engage the keepers 45 and 46, raising the member 26 to force the clamps into engagementwith the barrel and raising the barrel 01f the ground. The bar 42 may then be tilted slightly upward, raising the standards 4 so that the truck may be rolled over the surface which supports it, the barrel being held off the ground because the latches 43 and 44 are still in engagement with their keeper, loops. Whenthe barrel is to be released, the bolts 37 maybe withdrawn from the slots or notches 86 so that the clamps .will automatically release themselves,

What I claim and desire to secure by Letlevers, and means for locking said two sets i of levers together. 7

In a device of the class described, a frame, standards carried by the frame, sliding sleeve memberson the standards, barrel ,7

clamps carried by the sleeve members, wedges slidable on said sleeve members for adjusting the barrel clamps and means for imparting movement to said wedges.

4. In a barrel truck, a frame, standards carried by the frame, sleeve members slidable on the standards, ratchet bars slidable in the sleeve members, barrel engaging plates carried by the ratchet bars, wedges slidable upon the sleeves for engaging the ratchet bars and means for imparting movement tothe wedges to cause the ratchet bars to clamp the plates againstthe barrel.

5. In a barrel truck, a frame, standards carried by the frame, barrel clamps slidably carried by the standards and clamp actuat ing means to simultaneously clamp and lift the barrel for transport. I.

In testimony whereof I affix my signature.
