HOISTING APPARATUS.
SPECIFICATION forming part of Letters Patent No. 715,747, dated December 16, 1902.
Application iiled March 18I 1902. Serial No.' 98,835. (No model.)
T0 all whom t may concern:
Be it known that I, WILLIAM A. BooK, a citizen of the United States, and a resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Hoisting Apparatus, of which the following is 'a specification and which are illustrated in the accompanying drawings, forming a part thereof.
This invention relates to a hoisting apparatus which isparticularly designed to be used for charging refrigerators with ice and for similar purposes.
The object of the invention is to provide an apparatus of this character which shall .be simple in construction, which may be readily set upor erected for use, and which may be folded up in compact form, so as to be conveniently portable.
lThe invention consists of the combination and arrangement of parts hereinafter fully described, particularly designated j in` the claims, and illustrated in theaccompanying drawings, in which- Figure 1 is a view of the hoisting apparatus when set up or in operative position. Fig. 2 is a side elevation of the same. Figs. 3', 4, and 5 relate to details.
In the drawings I have shown the hoisting apparatus in connection with a refrigerator, a portion of which is shown and designated 9 and the door thereof 10, the invention being particularly adapted to elevating ice for filling refrigerators, although it is not restricted in its use to such purpose.
In carrying out the invention I provide a base 11,1designed to rest upon the floor or ground and supporting a standard which is vertically telescopically adjustable. To this end a tubular section or member 12 is fixed in the base 11 and receives an upper section or member 13, which may be held at any desired elevation by a clamp 14.. The upper end of the tubular member is split, asat 15, so that it maybe compressed by the clamp '14, which encircles the said split end about the upper member. This clamp is in the form of a split ring and is secured by a bolt -'16 and has extensions 17 at opposite sides thereof designed toserve as foot-rests, upon which thevattendant or operator may stand in order to have better access to the door of the refrigerator when filling the latter.
The upper end ofthe member 13 is provided with a socket 18, in which is swiveled an eX- tension'19, to which is connected on a horizontal pivot 20, so as to project at arght angle to the standard, an arm 21, provided with a lug 22, adapted to bear against the standard to prevent the arm from dropping down. The arm 21 is preferably made, as shown in Fig. 3, of parallel bars 23, connected at their free ends and provided with a grapple, preferably in the form of a pivoted hook 24, designed to engage under certain conditions with an eye 25, permanently attached to the front of the refrigerator.
A winch 26, having the usual pawl and ratchet 27, is secured to the lower member of the standard, and the cable or rope 29, Wound upon the same, passes to and over a sheave 30, journaled on the pivot of the arm 21 at the upper end of the extension 19, and then over a second sheave 31, journaled between the bars 23 of the arm 21, and has connected to its end a pair of tongs of any suitable construction, but which preferably consists, as shown in Fig. 1, of apair of arms 32, pivoted together and provided at their lower ends with gripping-pieces 33, provided with teeth and swiveled to the arms 32 in order that they may adjust themselves tothe faces of the block of ice being elevated. The upper ends of the arms of the tongs are connected by links 34 to a ring 35 at the end of the cable or rope 29.
36 designates a collar secured to the upper member of the standard and having pivoted thereto a platform 37, Which is designed to grapple or engage and rest upon a bracket 38, secured to thefront of the refrigerator just below the door thereof, the collar 36 being adjustably secured on the member 13 by a bolt in order that the platform may be adj listed to the proper height with relation to the refrigerator-door.
In storing away small pieces of ice the platform 37 is not employed, but is left free, as shown in dotted lines,`Fig. 2, the apparatus Ibeing held in position by the hook 24 of the arm 21 and the operator standing on the footrest 17 then being able to push the blocks through the refrigerator-opening without difficulty. When handling large blocks of ice, however, the platform is engaged with the bracket 38 and the hook 24 disengaged from the eye 25, so as to permit of the swinging of the arm 2l in a horizontal plane. As shown in full lines in Fig. 2, when the hook 24 is disengaged from the eye 25 it hangs down out of the way of the eye 25, so as not to interfere with the movement of the arm 21, The ice being lifted to the platform, the attendant has but to slide the same into the opening of the refrigerator, as will be readily understood.
To fold up the apparatus, the platform is disengaged from the bracket 3S and the arm 21 swung over on its pivot, so as to fallback of and parallel to the standard. The clamp 14c is then unloosened and the upper member of the standard telescoped into the lower member, reducing the apparatus to a compact and conveniently-portable form. The crank 39 for operating the winch is removable and may also be used for loosening the nut securing the clamp 14.
