My invention relates to a truck and I declare the following to be a full, clear, concise and exact description thereof sufficient to enable anyone skilled in the art to which it appertain to make and use the same, reference being had to the accompanying drawings in which like reference characters refer to like parts throughout the specification.

The object of the invention is to provide a truck that can be used in moving still drums containing oil or other substances that are stored in warehouses.

t is often found desirable to select certain of the drums thus stored for shipping. To this end the truck is made in such manner that it can be adjusted readily to the particular vertical heights of the drums that are to be moved and after loading the drum on the truck it can pass easily with the drum through a narrow lane formed by the remaining stored drums to a shipping platform for transportation.

The object will be understood by referring to the drawings in which Fig. 1 shows the device in perspective carrying a drum.

Fig. 2 is a detail view enlarged showing a perspective of one of the members employed in the structure.

Fig. 3 is a detail view enlarged showing a central vertical section of the member illustrated in Fig. 2 with other parts, some in full.

Fig. 4 is a detail view enlarged showing a central vertical section in full lines in one position and the same device in dotted lines in another position.

Fig. 5 is a transverse sectional view of the device taken on the line 5--5 of Fig. 4.

Fig. 6 is a detail enlarged view showing a perspective of a fitting employed.

Fig. 7 is a perspective view of the truck.

Referring more particularly to the drawings the device embodies a channel shaped casting member l having a central chamber 2 that is open at each end 3, 3. Casting I has projecting parts 4, 4 and a depending part 5 forming a socket 6 for housing the rotatable rod 1. Rod 1 is held in place in socket 6 by a screw bolt 8.

rod 1 by a spring pressed plunger member II. Member H has formed integral with its inner end a rectangular tongue l2 that projects into a horizontal groove [3 several of which are made at predetermined intervals by notching a sector of the outer surface of rod 1. Tongue I2 of member I l is held yieldingly in said horizontal groove 13 of rod 1 by a coiled spring [5 having one end housed in socket [6 of member H and the other end engaging the inner surface of screw plug [1 that is threaded to the internal threads of socket 29. A hollow handle member I8 is fastened at right angles to rod 1 by a headed screw bolt 19 that projects through the hollow handle member l8 and engages a threaded aperture in rod 1.

In order to move adjustable fitting 10 along rodl', whereby to engage the tongue l2 of plunger member I l with any one of the several notches it, it is necessary only to turn rod 1 about ninety degrees by means of handle it, whereupon tongue l2 will ride out of its engaging groove l3. The operator then can 'push fitting I0 along rod 1 to the desired groove I3 and again turn rod 1 by means of handle IS in the reverse direction. about ninety degrees, whereby tongue l2 will be pushed i into said groove is by coiled spring l5.-

The inner end of bolt 8 projects into an annual Fitting Hl'has formed integral'therewith and 1 in alignment with each other twin socket members 2!, 2|. Members 2!, 2| have sockets E22, 22 open at their lower ends. The interior walls of said sockets 22, 22 are threaded for the reception of the upper threaded ends of supporting tubes 25, 25. The upper ends of each of-said tubes 25; 25 extends straight down from sockets 22, 22 is bent at 26, whereby they diverge from each other. The lower ends of each of said rods 25', 25 is again bent at 21, 2?, whereby to extend straight downward into socket 28, 28 made integral with and upstanding from casting 30. An axle 3| extendsclear through a suitable aperture in casting 30. Wheels 32, 32 are mounted on those parts of the ends of axle 3| that project beyond casting 30 and are held in place by cotter pins 33, 33 extending through suitable apertures in the respective extended ends of axle 3|. Washers 34, 34 are mounted on axle 31 on the outside of wheels 32, 32, whereby to protect the bearings from dust and other foreignmatters.

The means for engaging the lower portion of the oil drum All embodies the forwardly projecting lugs M, ll are formed on the arc of a circle to conform with the contour of said drum 40.

The means for pivotally mounting the handle bar 42 contemplates rearwardly extending lugs 56, 46 formed integral with opposite ends of casting 30. A U-shaped casting 41 is fulcrumed to lugs 46, 46 by a headed shaft 48 that extends through aligned apertures in lugs 46, 46 and the cooperaitng parts 49, 49 of casting 41. A cotter pin 50 is projected through the extended portion of shaft 48 to hold it in place.

The handle bar 42 embodies a hollow tube 5I resting in a suitable annular groove 52 made on the under side of casting 41. A headed bolt 53 and nut 54 is used to hold tube 5| to casting 41. A handle 55 is held to the free end of tube 5I by a T shaped fitting 56.

The means for connecting tube 5I with casting member I embodies forks or links 60, 69. The upper ends of links 60, 60 project into chamber 2 of casting I and are pivoted on a shaft 6| having bearings in the lower part of casting I. Links 60, 69 are bent at 62, 62, whereby they diverge from each other. The upper ends of links 69, 60 disposed in chamber 2 of casting I form a rest for the free end of lower rock jaw 19 hereinafter referred to. The lower ends of links 60, 69 are pivoted to a headed shaft 63 which has a bearing in block 65 that is secured to tube 5I by a headed bolt 66 and nut 57. The

under surface or block 65 is curved to conform to the curvature of tube 5I. Cotter pin 68 passes through shaft BI to hold it in place.

The means for gripping the end of bead II of oil drum 40 embodies said lower rock jaw I which is fulcrumed on a headed shaft or pin I2 extending through aligned apertures in the parallel walls I3, I3 of casting I. A cotter pin I4 is projected through the part of pin I2 that extends beyond one of the outside walls I3, I3,

whereby to hold it in place.

An upper jaw I having a hook portion I6 cooperates with the lower jaw I0, whereby to grip the bead II of oil drum 40. Upper jaw I5 is pivoted on a movable headed shaft or pin I9 that has eccentric bearings in discs 89, 80 mounted to turn in walls I3, I3 of casting I. A cotter pin I8 is projected through an aperture in the part of shaft I9 that extends beyond the adjacent wall I3 whereby to hold said shaft I9 in place. Shaft I9 being mounted in said discs 80, 80 is movable from full to dotted line position illustrated in Fig. 3. When said discs are rotated in a clockwise direction they will allow upper jaw I5 to move longitudinally or rearwardly relative to lower jaw I0 as shown in Fig. 3, whereby to clamp bead II of oil drum 40 between the outer edge 8I of lower jaw I0 and the hook I6 of upper jaw I5 as seen in dotted lines in Fig. 3.

The means for returning upper jaw I5 and lower jaw III to normal or full line position illustrated in Fig. 3 contemplates a vertically disposed shaft 85 having a sliding fit in an apermm 86 in the upper horizontal part 8! of casting l. The lower end of shaft 85 rests in an open recess 88 made in the rear end of upper jaw I5, which is cut away on a reentrant angle at 89. Shaft 95 exerts a normal downward pressure against the rear end 90 of upper jaw I5 by reason of a coiled spring 9I that surrounds said shaft 85 and bears at its upper end against the lower surface of horizontal part 81 and at able apertures in the periphery of discs 80, 80. Said pins 93, 93 project into arc shaped slots 94, 94 made in walls I3, I3 of casting I. Said slots 94, 94 are adjacent to and open into the annular open apertures that house said discs 80, 8B.

A fioor support for holding hollow handle bar 42 in elevated position embodies a V shaped bracket I90 that is bolted at IUI and 53 to said tube 5I near its lower end. The lower part of bracket I00 is adapted to rest on the floor or other external support, not shown. A foot pedal I92 is welded or otherwise secured to bracket I90.

The operator after adjusting casting I as to height of selected drum 40 pushes the truck towards said selected drum 40 until lugs 4I, M are a short distance from its exterior lower part and tilts the handle 42 forward, whereby the outer end of lower jaw ID will engage the lower surface of bead II of drum 40 before the lugs 4|, 4| of casting engage the lower part of drum 40. He then puts his foot on pedal I02 and pushes the said lower casting 30 towards driun and simultaneously brings handle 42 backward, whereby to tilt casting I in the reverse direction and thereby force the outer edge of lower jaw '10 upwards against the lower surface of head II of drum 49. This movement will exert a pressure on said lower jaw III which will cause it to rock on its pivot I2 into dotted line position illustrated in Figs. 3 and 4, whereby the rear end of lower jaw III will exert a pressure on the rear end of upper jaw I5 whereby to rock it on its movable pivot I9 into dotted line position shown in Fig. 4. During this interval the force of coiled spring 9| on shaft 85 will be sufficient to prevent discs 80, from turning on their bearings, when upper jaw 15 has reached its dotted line position in Fig 2. A further push on pedal I02 will overcome the resistance of coiled spring 9| and thereby allow discs 80, 89 to turn clockwise on their respective bearings, whereby to cause pivot ID to move therewith into dotted line position illustrated in Fig. 4 and draw upper jaw I5 rearwardly rela tive to lower jaw I0 into gripping contact with the inner surface of bead II of drum 40 shown in dotted lines in Fig. 4. By further tilting the handle 42 the drum 40 will rest on the truck and can be carried to any desired location for transportation.

In order to release the drum 40 from the truck the above movements in the reverse order are made.

Cotter pin I05 will limit the movement of shaft I in fitting I0.
