TRUCK FOR LIFTING AND TILTING ARTICLES Filed July 30, 1929 2 Sheets-Sheet 2 described and the novel features thereof'par-- Patented -Mar. 31, 1931 I UNITED STATES PATENT OFFICE TEADDEUS s. TRULLINGER, or ASTORIA, oarieon,

. 'rnucx For, LIFTING-AND rrn'rrne ARTICLES Application filed July so,

I also contemplated that a barrel may be lifted by a movement of the operating parts which movement, in and of itself will lock the barrel,

so to speak, in elevated position until manually released so that it is a simple matter forone attendant to handle the barrel both to elevate it and tilt itfor any purpose desired.

With these and other objects in view the invention consists in certain details of construction and combinations and arrangements of parts, all as will hereinafter be more fully ticularly pointed out in the appended claims. In the accompanying drawings: Figure 1 is a front elevation of a truck embodying the present improvements, the barrel clamping member being shown partly open. Fig. 2 is a side elevation of the truck with the parts shown in the position they occupy when embracing a barrel to be elevated, the barrel being indicated in outline,

i Fig. 3 isa similarview with the barrel elevated and tilted, Fig. 4 is a detail vertical sectional view of the bearing for the barrel clamp,

Fig. 5 is a front elevation of form of truck and a Fig. 6 is a side elevation of the truck shown in Fig. 5.- I In the "preferred form of truck there are a 4 pair of base members 10 suitably supported -OIY' rollers 11 whereby it ma be propelled wherever desired. Extendingupwardly from each base member 10 is a vertically disosed standard 12 having therein a vertically 'sposed slot 13. Projecting1 through each "slot'is a bearing member 14 t e twobearings pivotally supporting af'barre'l encircling clamp by means of trunnions' 15 on said clamp projecting into said bearings. This barrel 5 encircling clamp, may, so far as the present a modified 1929. Serial No. 382,206.

invention is concerned, take various forms but preferably it consists of a band having two sections 16 hingedly connected to a body portion 17. Each of sections 16 has a flange -18 thereon and supported in one of said flanges is a bolt 19 adapted to project through the other. flange 18, the projecting end portion of said bolt bein slotted to receive a wedge20 whereby the band ma be clam ed around abarrel, it being un erstood t at practicall all metallic barrels of the present day are ormed with intermediate annular ribs or projections between which the band may be positioned. 7

Various mechanisms may be utilized for elevating the bearings 14 with the barrel supported thereon but preferably this elevating .mechanism consists of-levers 21 pivotedintermediat their ends on the standards 12, said levers being connected at one I end by a transverse-band bar and having their opposite ends offset laterally, as shown in Figs. 2 and 3. These offset end portions of levers 21 are connected to the bearings 14 by links 22, the links being at both of their ends to said parts. As shown in Figs. 2 and 3, the ivotal centers of levers 21 are vertically almed with the bearing members 14 and the links122 are of angular shape or offset to correspond with the offsets in said levers. With this arrangement, when other end of each lever and the connected end of each of the links 22 pass throu h and ivotallyattached.

' the handle ends of the levers 21 are depressed I for the purpose of elevating a barrel support- .ed between the standards by bearings 13, the

said links are located. Under these circumstances it is impossible for the barrel to drop and the attendant, after moving the levers to this position, can release the same so that he has both hands free to manipulate or tilt the barrel which is, at that time, fully elevated.

Inthe' form of apparatus shown- Figs.

5 and 6, the bearings 14' for the clamp trunnions are suspended by cables 23 from a' transverselyextending shaft 24 journaled at the upper ends of standards 12*, the cable being adapted to'be taken up by being wound around said shaft when the latter is rotated by crank handle 25. In this construction the barrel is retained in its elevated position by means of hook-shaped members 26 pivoted on shaft 24 and provided with recesses 27 for receiving the bearings 14* after the barrel has been elevated. These hook-shaped members swing freely on the shaft and drop under the bearings 14 when the latter are elevated as will be understood. However, to position the bearings 14* in the recesses in said hookshaped members the barrel must be slightly lowered after the hooks have dropped under said bearings. Likewise, before the barrel can be again lowered, it must be slightly elevated to disengage the hook members from said bearings.

IVhat I claim is:

1. In a device of the character described, the combination of a pair of standards each provided with a vertically disposed slot, members in said slots for rotatably supporting a barrel between said standards, a lever pivoted on each standard, and links connecting said levers and barrel supporting members for raising and lowering the latter, the handle portion of the lever and the connections between said links and levers being positioned at the same side of the pivotal centers of the levers when thebarrel supporting members are elevated.

2.- In a device of the vcharacter described, the combination of a pair of standards each formed with a vertically disposed slot, a lever pivoted on each standard, a link pivotally attached to each lever, bearings on said link projecting through said slots and vertically alined with the pivotal centers of said levers, and means for rotatably supporting a barrel on said bearings, the pivotal connections between said links and levers: being In vable v to one side of the pivots of said levers to lower said hearings in said slots and movable to the opposite side to elevate said bearings.

3. In a device of the character described, the combination of a pair of standards each the ofiset end of the lever being located at the same side of the pivotal centers of the levers as the handle portions of said levers when the barrel clamp is elevated.

5. In a device of the character described, a portable base, a pair of standards rigidly mounted on said base, a U-shaped member having oiiset ends pivoted on said standards and constituting a lever, means adapted to be clamped around a barrel, and a pair of links connecting the offset ends of said U- shaped member and said barrel clamping means whereby the barrel clamps may be raised and lowered, the connection with the oilset end of the lever being located at the same side of the pivotal centers of the lovers as the handle portions of said levers when the barrel clamp is elevated.
