JOHN OHRISTIANSEN, NEW YORK, Y., -ASSIGNOR TO HIMSELF YAND B. KREISOHER, OF SAME P LAOE. y
Leim Paare No. 7s,927, daae June 16, 1868.
`IlllPltOllliD HOISTINGi-PPARATUS.
To ALL WHoM 1T MAY c 'oNoEnNf Be it known that l, JOHN CERISTIANSEN, of the city, county, and State of New York, have invented anew and improved Hoisting-Apparatus; and I do hereby .declaretlxe following to beafull, clear, and exact description thereof, which will enable those skilled in the art to 4malce and usethe same, reference being had to vthe accompanying drawing forming part of'this specification, in which drawing- Figure 1 represents a transverse section o f thisinvcntion, taken in the plane indicated by the linewxJig. 2.v Figure 2 is a longitudinal section thereof, .the linc y y,lig. 1, indicating the plane of section.V Similar letters indicate corresponding parts. a i i This invention relates to airimprovement in that class-of hoisting-apparatus, the clicct ofii'hicli dependsupon'ftwo or more differential gears.
l The invention consists in a double-armed lever, placed loosely'on the drivingshaft of the hoisting-apparatus, and carrying two pini'ons, which'mesh intoV gears'mounted firmly on said driving-shaft, and vone of which-.also meshes into a stationary internal gear, while the other meshes into. cogs on theivinner surfacel ofgthe drum, to n'hich the-hoisting-rope is attached, said pinions and gears being so adjusted in relation to cach other that the gearsmbunted on the shaft have an equal number of cogs, while the number of cogs of the statonaryinternal gear is different from that of the number of the cogs of the internal gear in the drum, and the number of the cogs of one pinion different from -the number of cogs of the other pinions, {or-thejnumber of cogs of t-he internal gear may be the saine, and that of the other 'gears dierent, orthe number of coge on both pinions may be .the same, and that of the internal gears and of the gears on the driving-shaft diii'erent,) in such a manner that by the combination of said double-armed lever and gears 'with the drum', apowerful hoisting-apparatus is produced. The invention consists, also, inthe arrangement of a'stationary` rimand a series of friction-rollcrs,inv combination with one end of the hoisting-drum, the opposi-teend of which is supported on tlxe.drivingshaft, in such-a manner that Aa firm and `durable bearing for said drum'is obtained with the least possible friction.
A represents the driving-shaft of my hoisting-apparatus',which has its bearings in standards, B B', secured to a bed-plate or base, O, of any suitable nature. On this shaft areiirmly mounted-two gears, a a', one of i which gears into apinion, b, and the other into a pinion, b, and these pnions turn loosely on studs,'cc', which are 'firmly secured in avdouhle-armed lever, D. Snidelever turns loosely on the shaft A, and its arms maybe made to extend in opposite 'directions frmfthe centr 'of-the shaft, or they maybe at right angles, or at any other-desirable angle towards each other. l i
The pinion b also gears into a stationary internal gear, d, which -is rigidly connected to the 'standard B, andthe pinion b gears into an internal'gear, d', formed on the inner 'surface of the hoisting-drum E.
This drum has its bearings at one end on the shaft 1A,.and at the opposite end on a series of friction-rollers, e, which roll o n a rim,f, projecting from the standard B, so that both ends of said drums are Vwell supported, and the friction between the Working parts is reduced as much as possible. y
In turning the shaft Ajiy hand or other power, the pinions b b revolve around the gears a a', and if th'e proportion between the gears a 6 dis the saine as that between the vgears a' b d, t he hoisting-drum remains statinary; but if these proportions are different, so that the motion of the lever l), due to the pinion la, is diilerent from that which would hc' due to the pinion 1)',the hoisting-drum necessarily must turn enough to make up for this difference, and a powerful hoisting-effect is obtained.
It is obvious that in this arrangement the gears a a Ymay be alike, and the p nions b b and internal gears iid different in size, or the gears a a and pi'n'ions 6.5 may be dierent, Aand Ythe internal gears d alike, or the gears au and internal gears d d may be dilicrent, and the pinions I b alike, or all the gears maybe di'erf ent from each other without changing the effect, provided the proportion between the gears a I c l retains its relation to the proportion between the gears af b d unchanged.l X
Having thus described ,my inventi o n,.what1 claim as new', anddesire to secure hy'Letters Patent, is- 1. The combination of the lever D; carrying the pinions b li', with the shaft A gears a afinternal gears d d', stationary rimf, and drum E', substantially as `and-for thepurpose described.
2. The combination of the statinaryrim f supporting the friction-rollers e, with the hoisting-drum E, .substantially as and for the purpose set' forth. l A I l' i JOHN vCHRIsTIANsEN. I Witnesses: 4 l
