DRUM LEVER.

"Application filed February 14, 1927. Serial No. 168,199.

This invention relates in general, to levers for handling merchandise, and has more particular reference to a. lever especially designed for handling steel shippingdruins.

' It is becoining more and more the case that liquid and semi-liquid materials are being shlpped in steel drums rather than in the wooden barrels. These drums are cylindriv cal in shape, with an annular, outwardly projecting, flange positioned inwardly of each end a distance equal to one-third of the height of the drum, for facilitating rolling the drums when they are on their sides. At the ends, a reinforced flange projects aboutv one inch beyond the heads, on which the drums and that this is time consuming and expensive.

With the above and other considerations in mind, it is proposed in accordance withthis invention, to provide a lever for raising such drums to, and lowering them from, the standing position, which enables one man to do the work of two, and to do it in less than the usual time and with less effort.

More specifically, the invention comprises a shaft with a hand end, and an ad ustable hook near the other end, for catching under the projecting rim at the head of a drum, and

a heel for engaging one of the annular flanges is on the side of the drum.

Further objects, purposes, and character stic features of the invention will appear as the description progresses, reference being had to the accompanying drawings, showing,

solely by way of example, one form of the invention.

' In the drawings Fig. 1 is a side elevation of the lever in operative position; I

Fig.2 is a bottom plan view of a port on of the lever Q 7 a Fig. 3 is a top plan view of a portion of the lever, with partsbroken away; 1

Fig. 4 is a sectional view on line 4+4 of Fig. 3, with parts left in elevation; and

Fig. 5 is a sectional fragmentary view i1lustrating the adjustable feature of the device.

Referring to the drawing, the lever comprises a shaft 1 made of suitable material, such as hickory, of a length of perhaps five feet, and tapering slightly from the butt end to the hand end.

Adjustably mounted Onthe sliaft'fis a grip hook H made of cold rolled steel, for example. This hook is U-shaped, 'withinturned pointed ends 3, and a strap 4 welded or otherwise fastened across the legs 5 of the hook. The part6 connecting legs 5, is reduced slightly in diameter as at Land has a fiat portion 8 positioned at about a 15 degree angle to the legs 5. V

Mounted longitudinally of the shaft, in a depression 9, is a lock bed 10, furnishedwith a shackle bar 11, the bed and bar being connected together, and to the shaft, by through bolts 12.

' Formed in the lock bed 10, is a series of spaced arcuate grooves 13, formed on the same diameter as thereduced part 7 of the hood for rotatably receiving the hook, the reduced part 7 just fitting between thebed and the shackle as shown in Fig. 4, a sh'oulder'14 at each side'of the bed 10 preventing longitudinally sliding of the hook. I

Whilethe distance fromthe inner surface of the shackle 11 to the lowest part of a groove 13, is just equal to'the diameter of the reduced part 7 the distance to the top fiat part as shown in Figs. 4and 5, the hook H can not beadjusted from one position to another on :10 of the bed 10,1is just equal to the thickness of thehook bar taken at the fiat part 8. Thus,

gles to the shaft 1, but can be thus adjusted, i

only when rotated toward the handle end of the shaft until the fiat part 8 is parallel to the shaft axis, i. e. until the hook legs 5 make an angle of'approximately 15 degrees with the axis of. the shaft. Rotation of the hook in the opposite direction, to the other side of the shaft, ispreventedjby the strap 4, to thus prevent rotation of the hook toward the butt end of the shaft from positioning the flatv part 8 so as topermit adjustment of the posie tion on the hook on the shaft. I

On the opposite side of. the shaft, and near the end of same, is a heel portion comprising a transversely cut notch 15 slightly tapering inwardly, and of a depth to accommodate a drum flange. The upper edge of the notch is protected by a steel plate 16 held in place by a through bolt 17 and having a serrated edge 18 for gripping onto a drum.

The lower edge of the notch 15 is protected by a soft steel plate 19 with a serrated edge 20, held to the shaft by wood screws 21 with countersunk heads, and riveted or welded to, or formed integrally with, a steel ring 22 encircling the butt end of the shaft and held in place by screws 23.

As shown in Fig. 1, the butt end ofthe shaft.

1 is tapered on one side, fromthe lower edge of the notch 15 to the end of the shaft and covered and protected by the soft-steel plate 19 and ring 22. j

The lever described above is usedin the manner shown in Fig. 1, where a drum D is aeing raised from its side to one end. The grip hook H is adjusted in position, so as to be substantially 90 degrees to the shaft, when it engages the end flange 24 of the drum, and the heel of the lever engages a side flange 25 as shown. The soft steel plate 19 contacts with the drum surface to give a large bearing area, but can not injure the side of the drum. By raising or lowering on the shaft 1, the drum 1) is correspondingly moved.

On rotating Fig. 1 90 to the left, this figure illustrates the drum being lowered from its end to its side, and this operation is as iinportant,as that of raising the drum from its side to its end. j A

While but four adjustment positions for the hook H have been shown, more could be provided if need be. The four positions shown, however, place the hook for operating on the various sizes of drums commonly encountered in practice, namely 27", 30", 36 and l0-42". i

It will be seen that with the lever described,

. the hook H can not slip out of adjustment by accident, but must first be rocked upwardly, as in Fig. 5; that such hook canbe adjusted for operation on drums of various sizes, that the heel is arranged and constructed to give a good grip and bearing surface without injuring the drum, and that the various cons ituent partsare simple, rugged tive.

Merely by way of example, it is to be noted that the inventor, with the sole aid of a lever as describedabove, unloadedand stored away, 'a carload of Hytempite, the carload consist ing of drums, each weighing 84:8 lbs. gross, each drum being taken from end to-side position, and again restored to end position for storing. This was accomplished in one-third less b11116, and with less effort, than two men including himself, had everbefore done the same job, andin the very same storehouse.

The above rather specific description of one form of this invention has beengiven solely by way of example, and is not intended, in

and etl eo any manner whatsoever, in a limiting sense. Obviously, the invention can assume many different physical forms, and is susceptible of numerous modifications, and all such forms and modifications are intended to be included by this invention, as come within the scope of the appended claims.

Having described my invention, I now claim 1. In a drum lever, a shaft, a grip heel on the shaft, a hook adj ustably held on the shaft, and means permitting adjustment of the position of the hook longitudinally along the shaft only when the hook is placed in a single predetermined position relative to the shaft.

2.
