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 theline 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 acentral chamber 2 that is open at eachend 3, 3. Casting I has projectingparts 4, 4 and a dependingpart 5 forming asocket 6 for housing therotatable rod 1.Rod 1 is held in place insocket 6 by ascrew 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 ofrod 1. Tongue I2 of member I l is held yieldingly in saidhorizontal groove 13 ofrod 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 torod 1 by a headedscrew bolt 19 that projects through the hollow handle member l8 and engages a threaded aperture inrod 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 turnrod 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 alongrod 1 to the desired groove I3 and again turnrod 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 ofbolt 8 projects into an annual Fitting Hl'has formed integral'therewith and 1 in alignment with each othertwin socket members 2!, 2|.Members 2!, 2| have sockets E22, 22 open at their lower ends. The interior walls of saidsockets 22, 22 are threaded for the reception of the upper threaded ends of supportingtubes 25, 25. The upper ends of each of-saidtubes 25; 25 extends straight down fromsockets 22, 22 is bent at 26, whereby they diverge from each other. The lower ends of each of saidrods 25', 25 is again bent at 21, 2?, whereby to extend straight downward intosocket 28, 28 made integral with and upstanding from casting 30. Anaxle 3| extendsclear through a suitable aperture incasting 30.Wheels 32, 32 are mounted on those parts of the ends ofaxle 3| that project beyondcasting 30 and are held in place bycotter pins 33, 33 extending through suitable apertures in the respective extended ends ofaxle 3|.Washers 34, 34 are mounted onaxle 31 on the outside ofwheels 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 saiddrum 40.

The means for pivotally mounting thehandle bar 42 contemplates rearwardly extendinglugs 56, 46 formed integral with opposite ends ofcasting 30. A U-shapedcasting 41 is fulcrumed tolugs 46, 46 by aheaded shaft 48 that extends through aligned apertures inlugs 46, 46 and thecooperaitng parts 49, 49 ofcasting 41. Acotter pin 50 is projected through the extended portion ofshaft 48 to hold it in place.

Thehandle bar 42 embodies a hollow tube 5I resting in a suitableannular groove 52 made on the under side ofcasting 41. A headedbolt 53 andnut 54 is used to holdtube 5| to casting 41. Ahandle 55 is held to the free end of tube 5I by a T shapedfitting 56.

The means for connecting tube 5I with casting member I embodies forks orlinks 60, 69. The upper ends oflinks 60, 60 project intochamber 2 of casting I and are pivoted on ashaft 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 oflinks 69, 60 disposed inchamber 2 of casting I form a rest for the free end oflower rock jaw 19 hereinafter referred to. The lower ends oflinks 60, 69 are pivoted to aheaded shaft 63 which has a bearing inblock 65 that is secured to tube 5I by a headed bolt 66 and nut 57. The

under surface orblock 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 ofoil 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 ofoil drum 40. Upper jaw I5 is pivoted on a movable headed shaft or pin I9 that has eccentric bearings indiscs 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 saiddiscs 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 ofoil 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 disposedshaft 85 having a sliding fit in anapermm 86 in the upperhorizontal part 8! of casting l. The lower end ofshaft 85 rests in anopen 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 therear end 90 of upper jaw I5 by reason of a coiled spring 9I that surrounds saidshaft 85 and bears at its upper end against the lower surface ofhorizontal part 81 and at able apertures in the periphery ofdiscs 80, 80. Saidpins 93, 93 project into arcshaped slots 94, 94 made in walls I3, I3 of casting I. Saidslots 94, 94 are adjacent to and open into the annular open apertures that house saiddiscs 80, 8B.

A fioor support for holdinghollow 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 selecteddrum 40 pushes the truck towards said selecteddrum 40 until lugs 4I, M are a short distance from its exterior lower part and tilts thehandle 42 forward, whereby the outer end of lower jaw ID will engage the lower surface of bead II ofdrum 40 before thelugs 4|, 4| of casting engage the lower part ofdrum 40. He then puts his foot on pedal I02 and pushes the saidlower casting 30 towards driun and simultaneously bringshandle 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 ofdrum 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 coiledspring 9| onshaft 85 will be sufficient to preventdiscs 80, from turning on their bearings, whenupper jaw 15 has reached its dotted line position in Fig 2. A further push on pedal I02 will overcome the resistance of coiledspring 9| and thereby allowdiscs 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 ofdrum 40 shown in dotted lines in Fig. 4. By further tilting thehandle 42 thedrum 40 will rest on the truck and can be carried to any desired location for transportation.

In order to release thedrum 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.
