My invention. relates to portable hoisting apparatuses in general and more particularly to a device herein designated as a barrel lifter and conveyer designed mainly for the-purpose of lifting, conveying and setting oildrums in accessible positions. Other uses and objects of .the invention are hereinafter fully. set forth, reference being had to the accompanying drawing, in which,- Fig. l is. an end elevation of my device in operative position straddling an oil drum about to be raised from the floor. v

Fig. 2 is a right side elevation ofFig. 1. I Fig. 3 is anenlarged sectional elevation of the hoisting means used,.about as on line 3;-3 g f Fig. 1. Fig. 4 is aright side elevation: of 1g.3.. 1 F ig; 5 is a modification of Fig. .1 omitting the hoisting apparatus and showing a remove able barrel support for storing'an oil; drum within the frame.

. Figs. 6 and? are respectively front and side elevations of a' floor engagingauxiliary rack andthe lowerhalf of an oil-drum supported in elevation position.

Referring to the drawing by reference nume'rals, my device comprises a main frame consisting preferably of two inverted U- shaped bars 10, the lower extremities of which are provided with sockets forjcasters 11.. The said bars 10 are preferably-each a single piece of channel iron, and are'retained ri idly in spaced parallel relation to each other by suitable side bars such as'the two crossed bars 12 (see Fig. 2). The top parts of members 10 are on a common level and may be permanently covered as with cover boards 13, designated by dotted lines in Fig. 2, said cover boards being available for storage of various articles.

The main frame thus far described is, of course open at both ends and portable on its castersto be placed in longitudinal position over and straddling an oil-drum. 14 as best shown in Figs. 1 and 2; Such drums are commonly made with" integral spaced, encircling beads 1413 on which the drum rests, as on a floor 15, supporting the main body of the'd'rum spaced slightly above the floor. This enablesa metal ring. 16 torbe slipped concentrically inwardly and around-each end of the drum, the ring being of course of a" size-to loosely .encircle the drum. .17 is a chainrattached with one end to'the ring and adapted to be extended vertically toward the horizontal part 10H, where a link may 'be en'- gaged on an outwardly projecting prong 18 fixed in said part 10H, the said prongscom prisingpreferably a pin retained transversely in bar 10H and protruding inwardly of 30 said bar also, as at 18A. Each chain is of such length as to extend witha few links above its link which contacts with prong 18 and when its ring 16 is in loose contact with a drum 14 resting on floor 15. 1

. 19 in Fig. 1 designates an arched brace in the upper part of either'end frame 1010H. An oil-drum and my device are placed in the position shown in Fig. 1 preparatory to raising the drum to a pre-determined height for tappin'gthe latter, and certain hoisting means are provided for pulling the rings 16 upwardly by engaging the chain in successive actions by a lever device which will now be described. p

The hoisting device comprises a beam-lever 20 pivoted at 21 between two parallel upright ears 22E of a lever-bracket 22 adapted to rest on the top of bar 10H and having a downward integral lug 22L perforated so as to be slipped onto and removably engage the inwardly projecting part 18A of pin 18. The lever is movable in a vertical plane, and has a short forward arm with its extremity formed as an upwardly open hook 20H, while the other arm is relatively long and used as a lever. Obviously the lever 20 is normally positioned directlyov'er pin 18, particularly its short outwardly directed The lever is so proportioned that when its long arm is about vertical, its short arm is directed out and down'and its hook'20H' engageable with a link of chain 17 just above the link of the latter 17A (Fig. 3) which engages pin 18. Then lever 20 is swung inwardly as indicated' by arrow 23, the short ar'mof it moving out and upwardly as 'indicated by the arcuate line 24 This. action or arcuate outward movement ofho'ok 20H pulls the chain 011' of prong 18 but continued move- 17A and raise the drum accordingly step by 1 step.

The hoisting means just. describedlmaybe provided one for each end of the frame to raise both ends of a drumsimultaneously, if

so desired. However, this is deemed unnecessary as one hoisting device may suflice.

After a hoisting action has taken place at one end of the frame it is freely removed from contact with peg 18A and transferred to the other end of the frame to raise the other end of the drum 14. L

25 designates the outlet of an oil-drum in which may be put a suitable tap 26 to be used only when the. drum is elevated sufficiently to tap the contents as needed, as into a container 27.

In some cases it may be desired to use my device as a holder for the drum until it has been emptied. In this case I provide a removable skeletonized metal frame 28 (see Fig. 5) insertable between the vertical members 10 and retained therein at a suitable height by merely providing removable pins 28F retained in properly located apertures in the members 10 at each end of the main frame. Obviously, a drum is easily raised as described, thenv a pair of support frames 28 set in place under it, and the drum is then lowered to come. to a rest on the said support frames. It will now bereadily understood that a drum thus elevated in the rack and retained therein may be readily moved about to any desired location, I

In other instances myportable device may be used for moving and placing a number of drums invarious locations, or in groups. For this condition I provide a secondary or auxiliary rack best shown in Figs. 6 and. 7. This auxiliary rack comprises two identical end frames each consistingof a pair of legs 29 connected at their upper ends by a downwardly arched strap 30 suitably braced as at 31, said end frames being connected by side braces 82. This entire auxiliary frame is of such size as to be placed longitudinally under an elevated drum 14, the drum being let down to rest on the arched members 30, after which the portable hoisting frame is wheeled away. i I

The use of my device has been fully disclosed inthe foregoing specification. Various modifications of structure may be embodied without departing from the scope and spirit of the invention. The article is par ticularly useful for so called gas and oil ward the "prong to engage it with another link of the .chain raised to a position fora such engagement and simultaneously hoists the drum 1 1.

I claim 1 1; Adrum rack'an'd conveyer of the class described comprising an upright roller supported main frame having downwardly open end frame'members braced and connectedto each other at the side and top parts, said main frame being adapted to be positioned longitudinally over and straddling a cylindrical drum or the like, a'pair of ring members adapted to loosely encircle opposite end parts of such drum, a chain for each ring and extending upwardly from it toward the upper central part of each end frame member, lever actuated means at said latter part adapted to engage the chain and pull it-upwardly to raise the drum in successive lever actions andmeans on the frame for engaging the chain, other than the lever means, before and after each hoisting action of said lever means. 1

2. A portable barrel lifter and conveyer device comprising a roller supported main frame consisting of two arched endmembers, opposite'ends'ofsaid frame opening downwardly and side'brace means rigidly connecting said end members, said frame being adapted to be positioned to straddle a barrel or the like, a barrel engagin ring member for each saidarched frame en to encircle the barrel in approximatelya common vertical planewith said frame end, a chain extending upwardly from each ring toward the upper-central part of the frame end, a prong in said latter part arranged to be en'- gaged by a link of the chain, and a hoisting apparatus mounted on the frame over said prong and comprising a beam lever with a short hooked arm positioned over saidprong and a long arm integral thereof, the end of said hooked arm being oscillatable in an arcuate path over the prong and adapted to engage a link of the chain above said prong, said short lever arm being adapted to be moved upwardlyby downward movement of the longarmto first disengage the chain from the prong, then move it upwardly and subsequently inwardly tore -engage the prong with a lower link of the chain.

The structure specified in claiml in which said lever actuated means comprises a movableunit consisting of a lever, a lever bracket adapted to removably engage the top part of an end member of the main frame, said lever being fulcrumed in the bracket, a perforated lug on said bracket and means on the frame comprising a fixed pin to engage and hold said perforated lug and the lever bracket during hoisting action.

In testimony whereof I aflix my signature.
