Application filed March 22, 1887.

To @ZZ whom it may' concern.:

f i Be it known that LWILLIAMTHORNBURGH,

of vElyri`a,`in the county of Lorain and State .of Ohio, have invented anew and Improved Hos'ting and Conveying Device, of WhichY the following 'is a full, clear, and exact descrip- 'lhe object of muy invention is to provide a new and improved hoisting andconveying ma# ,chine which is durable Lin construction and Yvery veffective and rapid i'nfoperation.4

)The lnventlon consists intheconstruction and arrangement of various parts and details and combinations of the-same, as Wili be fully the claims. Y Reference is to be. had to the accompanying drawings, forming a part ofthis-specitiation,

described hereinafter, and then pointed out in in which similar1 letters of reference' 'indicate cres'pcndivg, parte" inf fall the, figures: "Figure l'is Va. sectional'front elevation of my improvement.' Fig. 2l isl a Side elevationl of the same onv the line :1v-:v of Fig."1. Fig. '3 is an enlarged 'sectional plan vieur` of the same A, andxthelsaidbushin'gs, are adapted to' be tu'r'ned in thesaid Vbearings by tliehandleCf, secured to the said bshingsG?. 'Thepulley C is located in such amanner that it can be y.moved in contact ,with thejsz'iid, main-shaft pulley', and atthe samei'time is moved in frictional contact With the pulley D, secured tothe shaft D', adapted to slide Vlongitudinally on bearings securedjtotherjnain frame A.

Th'e shaft D', is moved sidewise by a handle, E, providedv'vithalmiddle part, E', held at an angle tothe shaft DT, and passingthroughan" aperture formed in the 'ear D?, secured to theV shaft D. The ends El of (the arnrEstand at right angles tothe shalt D', and are mounted, inbearingsE, secured 'to the main frame A.

- i The shaft D is provided near one end with the bevel gear-Wheels F and F', adlptcd to eugage alternately the bevel-pinion Ff, secured to the shaft F, mounted in suitable bearings on thernain frame A, and' thc Suid shaft cnrries'a'worm, G. On the other end ofthe shaft D' aresecured the bevel. gear-wheels and E adapted to engage 'alte'nnateiyV the bevel pinion H, fastened on the shaft-YH?, mounted .in suitable bearings secured to the main frame A,andthe saidpshaft H3 carries worin G',

The worms' G and G' mesh inte the seilalixir-- culanworm-wheels I and I', sccured'to a shaft,

vI?, mounted in suitable bearings on top ofthe .main frame A. `O`u, the seniicircular wheels I and I' are secured the side, artlns, .1', of the v,h'isting-frameJ, which is provided `with, the

ofl'ltercross:beam, Jj, uniting the saidsidc To the indelen-f the absehen; .Ji-are secured the bearings J3, in which isf vnionx'itfed to turn the hollow 'pulley -liangcrV `Shaft' E, Supporting the pulleys KarfidzK over whichvpasses part of the doubled vro pfe', Il, supporting in the middle of the frame J, the carrierfpnlly N, provided; with n hook, N Y"- Thpers of the rop@v D passing over the g pulleys K' 'diverge inoppo'site directionsand vpass through theV hollow pulleyhanger vshaft AK, upon andV over the pulleys O.,O and. O'Of,

andfthen pass between `therpulleys Oheld inw the main `frame A, and thenthe ends'. of.` the y ropeL are wound; upon the respective drums PQE, secured. to thejshaft P', mounted in, "the eccentric bushings P', held inbeariugs secured .tothe'main frame A. The eccentric bushings '13"' aresiinilar in construction tothe eccentric 'bushings C, and are cach provided-withA au arm, Pf?, by which'the saidbushings andlv the shaft Plcan be turned so us lo move thcvpul-Iy fleyQ, .secured to the shaft 1?', into an outer frictionalfcontact with the pulley-R, attached4 tothefmain shaft B.

,Thedoperatiou is as follows: A continuous 'rotary motion isimparted to the mainshaft B Vbydsuitable' means, and the frict'ien.-pulleysQA :and Ciar'eheld out. of f rictional4 contact with fthe pulleys B and Ron the saidv main shaft B,

utilrequired. If-the'rnachine1 is in the positionvshown in'Figs. 1 and Zand the load held Vonthe hook N' is tobe hoistedvstraight up,` th'enfthe pulley Q [Ais'throwu in frictional coutact with the main-shaft pulley R by moving.

thrown out of frictional contact with ,the pul-Y ley R and the shaft P' is held in a locked position by suitable means. (Not shown.)V If it is desirable to move the load sidewise, then the pulley C is thrown in frictional contact with the pulley B'on the main shaft B. and at the same time with the pulleyD on the shaft D', and simultaneously the arm E is moved y )correspondingly inward or outward, as either kas the bevel gear-wheels F and H or F' and H' are thrown in or out of meshwith the pinions F and H, which are thus rotated in one direction, and cause the worms G and G' to turn the semicircular gear-wheels I and I', whereby the frame J is swung at its lower end to one side. It will be seen that as soon as the frame J leaves its vertical positipn the Weight ofthe load will cause the pulley-hanger Kto turn in its bearings J3 on the cross-beamsl J, so that the pulleys K' and K keep in line with the load and the rope L is not displaced from the said pulleys K' and K2. As soon as the frame J is swung to one side until its desired position Ais reached, then the load can be lowered by unlocking the shaft Pand operating the levers l, so that the shaft P' is free to turn and nnwiuds the rope L from its drums P. The pulley R on the main shaft B can be used as a frictional brake-wheel in case the, load is very heavy and descends' very rapidly.

A load can be hoisted when the frame J is in a sidewise position by throwing the pulley Q into frictional Contact withthe pulley R 0n the main' shaft B by turning' one of the levers l of the eccentric bushing P?. The frame J is swung into a vertical position or to the opposite sideby moving the arm E, so that the disengaged set of bevel gear-wheels F H or F' H on the shaft B is thrown in-ulesh with the bevel-pinions F", whereby the worms G. and G are rotated in an opposite direction and impart a similar motion to the simicireular gear-wheels I and l', which causes the frame A to swing upward to a vertical position and then to the other side.

The frame A is preferably mounted on wheels traveling on a track, so as to permit of moving thc machine rapidly from one place t0 another.'

It will further be seen that both shafts D and P can be set in operatiouat the same time, whereby the load held on the carrying-pulley N is raised, and at the same time the frame J swings on its fulcrum the shaft I.

The machine can be used for hoisting, loading, unloading, or discharging iron or coal or other material out of or ofi` from vessels, cars, or other places, and putting the same upon cars, docks, vessels, or other places, or depositing the same in holds of vessels or elsewhere, and the machine also serves for hoisting ore, coal, or other material for any purpose whatever.

It will be seen that by my improvement I obvate the necessity of using separate power for each machine and am able to work all the hatches of a vessel, for instance, at one and the'same time.U A
