I P HT R UNITED STATES PATENT OFFICE.
LEONARD HQHALL, OF ERIE, PENNSYLVANIA.
HOlSTlNG- MACHINE.
SPECIFICATION forming part of Reissued Letters Patent No. 9,095, dated February 24, 1880.
Original No. 210,850, dated December 17, 1878.
i To all whom it may concern --Be it known that l. LEONARD H. HALL, of
'Erie, in the county of Erie and State of Pennhoisting-cranes for use on docks, 860.-
My invention consists in the construction of the means for swinging the crane, and also various details about the machine.
My device is shown in the accompanying drawings, as follows, (there being two sheets, Sheet 1 containing Figure 1, and sheet 2 containing Figs. 2, 3, and 4 Fig. l is a perspective view of the hoisting-machine. Fig. 2 is a horizontal section through the axis of the shafts. Fig. 3 is a transverse vertical section on the linear to, Fig. 2, and shows the parts beyond in elevation. Fig. 4 is a transverse vertical section of a journal-box on the line y 3 Fig. 2.
The parts are designated by letters, as follows: A A A represent a frame-work. B B B represent the crane. O G are the drums, and c the chain by which the crane is swung. D is the main hoisting-drum or windl'ass. D is the bucket or object to be raised, and d is the hoistin'g chain.
The main shaft of the machine, or the one which communicates with the engine, is marked G. All the other parts of the machine receive their motion from the shaft G. I provide friction-wheels for communicating this motion.
The friction-w heel G operatesupon the friction- -wheel G,'which revolves the shaft H, which so shaftllis journaledin aswiveled journal-box,

truly journ aled, no matter at what point it sets. The shaft H is always in gear with the windlass D by the wheels F F, and hence the wheel G revolves, whether the object D is being hoisted or lowered; and the lever h can throw the wheel G" against the dead friction-block 0, as well as against the live friction-wheel G. So the operator at the lever ,h can regulate the speed of thedownward movement as easily as he can throw the machinein gear for hoistin g.
The device for turning the crane consists of a drum or pulley, O, on the mast or post B, a drum or winch, C, and an endless chain, 0, connecting the two.
This device is operated by being. connected with the shaft G by a friction device, which is constructed and operates as follows: The winch 0 receives its motion directly from a shaft, i, which is parallel with it, and is provided with'a pinion, J, which gears into another pinion, J, on the winch. The opposite end of the shaft 6 is provided with a conical friction-wheel, I. The shaft G is provided with two cones, I I, which are joined so as to form one solid spool, the two frustums having their small ends toward each other. This device, by a spline-and-groove arrangement, slides on the shaft G and revolves with it.
By means of yokes k k, sliding bar K, and lever K, either of these frustuins I or I can be thrown into gear with the frustum 1, and in this manner the winch O can be revolved in either direction at pleasure, and thus the crane can be swung in either direction by the operator moving the lever Kas he desires; or by settingthe lever K properly, so that there is no contact between the wheel I and either of the wheels or frustums I or I, the crane will not move at all one way or the other.-
' The shaft G, on which the friction-gears G and I I are placed, is, in eflect, an extension ofthe shaft of the engine which ,propels the hoisting-machine.
By the use of the friction-gears I I the swinging drum 0 can be thrown into operation at any time without shutting down the operator can raise and swing; or lower and swing, or'raisc or s ving alone, at pleasure, without altering the speed or reversing theengin'e. I
What I claim is as follows:
- 1. Ina hoisting apparatus which has acrane adapted to he swung, the combination; with said crane, of the drum'or pullcyG', cliaiuc drum 0, pinions JJ, shaft '13, and conical frictionwhcels I l I, eonstructedaml operatingsubstantially as and for thepurposes mentioned.
2. In combination with thedrum O, shaft 13, and cone friction-wheel I; thesha-ft G, sliding double-conefriction-wheels I I", yokes k k, sliding bar K, and lever C, said parts being arranged and operating substantially as and for the purposes mentioned.
3. The (mmbination, in a hoisting apparatus,
oft-he hoisting-drum .1), wheels F F, and shaft' H; which is jonrnaled atone cnd in a swiveled journal-box and at the other end in an eccentric I operati n g substanti journal-box, and bear-sat that enda. friction-I wheel, G'l, which operates, in conjunction with a friction-wheel, upon the main shaft, or upon a dead friction-block, O, as regulated by said eccentric journal-box H',' when moved by the lei'er h, substantially as and for the purposes set forth 4. The combination, upon the main shaft of ahoistingapparatus. of the frictimmiheel G for operating the hoisting-drum D, and the iii'iction-vwheels l.", for operating the swinging drum 0, said parts being arranged and ally asand for the purposes herein set forth.
In testimony whereof I, the said LEONARD H. HALL, have hereunto set my hand.
