IMPROVEMENT IN ROTARY'` MECHANICAL POWER.

The Schedule referred to in these Letters Patent and making part of the same.

To cllvhont'lt may concern:

Be it known that I, ADDISON GJWATERHOUSE, of San Francisco, in thecounty of San Francisco,v and State of California, have invented a new and useful Improvement in Rotaryli/Iechanical Power; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the drawings, and to the 'letters of reference marked thereon. l j Y My invention relates to that` class of mechanical gear in which a circulating cog-wheel propelled by a revolving eccentric or crank-shaft, operates within and upon a larger revolving cog-wheel, concentric with said driving-shaft, so as to rotate the said revolving cog- `wheel by'a slower motion than is :imparted to the driving-shaft, but with a proportionate increase of power;

and y lMy invention consists, first, in controlling the movement which is given tothe `circulating cog-wheelby `the eccentric or crank, by means of a sliding ring or cross-arm, having an independent sliding bearing on opposite sides of the revolv'ing'sllafnand upon which ring or cross-arm the circulating wheel has a similar independent sliding bearing on opposite sides of the shaft, in a lineat right angles to jthe sliding movement of said sliding ring or cross-arm; and

4 My invention further consists in making the inner portion of the circulatingcog-wheel, which bears and slides ldirectly uponthe` sliding ring or cross-arm, in

. the form of atletachable plate, which may be connected with or disconnected from said circulating cogwheel, by means of an adjustableclutch, at pleasure, so that by disconnecting said plate, the circulating y cog-wheel will ceasefto act upon thevonter cog-wheel, and the latter will rotate with the same-velocity as the revolving shaft.

My invention consists, further, in placing the revolv- :ing driving-shaft within a hollow stationary shaftfand `in placing the sliding ways or bearings ofthe sliding ring or cross-arm upon the end of said stationary shaft,

as hereinafter more particularly described.

My invention is applicable to ship-Winches, capstans, windlasses, and all kinds of rotary machinery for concentrating power.

In the accom panying drawings- Figure 1 is a central vertical section of a ship-winch, Y'

made pursuant `to -my invention, divided in line :t at',

iig. 3. l

` v Figure 2 is a central vertical section of the same in line y y, fig. 3. K Figure 3 is an end view of the same, with the cover removed, to show the internal structure.

Figure 4 is a view of the circulating wheel moved bythe eccentric.

Figure 5 is the sliding ring, which controls the movement of the circulating-cog-wheel.

. Figure 6 vis a circulating plate, which, when in operation, is secured tothe circulating cog-whcel by a clutch,` and becomes a portion thereof.

Figures 1l and 12 are views of the rotating shaft and the eccentric or cam which operates the circulatingwheel. i l

A is the body or drum of the winch;

A', a' removable cover to the same; v,

B, the revolving driving-shaft;

B, the eccentric, mounted thereon;

yC, the hollow stationary shaft, on which the drum revolves;- and D, the crank, by which the power is applied.

E is the outer revolving cog-wheel, which is made fast to the drum A, and revolves with it;

i F is the circulating cog-wheel, moved by the eccentricB; f is a circulating plate, forming a part of the circulatingwhe'elF, when con uected therewith by a clutch and g is the sliding ring, which controls the movement ofthe'circulating wheel.

H is a circular disk,rigidly`attached to the inner end of thehollow stationary shaft C.

On the face of the disk are two raised ways, h h., shown in iig. 10, extending radially on opposite sides of the revolving shaft.

The inner sideof the sliding ring g has recesses y' g von' opposite sides, which lit ldown upon said ways It h, so that saidring g can freely slide `to and fro on said ways, which are stationary.

vOn'the opposite side of, said ring g, are two simil-ar recesses, ifi, at right angles with the recesses g, -and on `the innei1 face of the circulating plates f are two raised ways, 7' j, opposite each other, which fit into the recesses t t' in the ring g, and allow the circulating plate f (and the circulating cog-wheel F, when attached thereto by the clutch,) to slide to and fro across the ling g, in a line at right angles with the' sliding motion of said ring g upon the disk H.

round a circle, but the wheel notrevol've around its own axis; consequently, said wheel F, by its circuiating motion within the larger wheel. E, successively engages, on all sides, with the cogs of said wheel E,

and at eac-h revolution of the driving-shaft, moves thesaidwh'eel E to the extent of one cog.

' In the drawing, the revolving wheel E has eight A cogs, and, consequently, it will require eight revolutions of the driving-shaft-to rotate said wheel once. It is `manifest, however, thatthe gearing may be ,so modified as to increase or diminish the difference 'betweenthe' speed of the driving-shaft and the rejecting from it a series of studs or clutch-pins, k,

which fit into a corresponding series of recesses k', in the-circulating plate f.

The said wheel Fis connected by three or more sliding rods, l, passing through the cover A', with a cap, L, outside of said cover. By pressing said cap L inward, the studsor clutch-pins k, on the inner face of the circulating` wheel F, are made to engage with the recesses k in the .circulating plate f, and so said plate becomes, practically, a part of the circulating cog-wheel, but, by drawing out the cap L, said circulating wheel F becomes disengaged from the plate f, and partially enters the cavity in the cover A', and there engages with a set of cogs, m, in said cover, which is .rigidly fastened upon the rotating shaft, so that the revolving shaft and the drum will then revolve together' at the same velocity.

On the, outer side of the wheel F is a raised annular flange, l', forming under it an annular groove, into which hooks, on the inner ends of the rods l, enter, so as to clutch the said wheel for the purpose of moving it in and out, without preventing it from rotating.

Said annular flange l is eccentric to the revolving shaft, coinciding with the eccentric B', and the sliding rods l are set in a correspondingly eccentric circle in the cover. v

In'any machinery where it is desired to have a uniform rate of power', in proportion to theforce applied to the driving-shaft, this clutching-device may be dispensed with, and the circulating plate f may be permanently attached to the circulating cog-wheel, or, in other words, may simply be a part thereof, and not a separate plate.'

It is obvious that by applying. the driving-power to the outer revolving cog-wheel, the same gear may be 4used to accelerate motion, but in so using it I prefer a crank to actuate the circulating cog-wheel instead of the eccentric B.

Insteadof a ring, g, to actuate the circulating wheel, cross-arms maybe substituted, in which case, two of the opposite radial arms will slide in suitable groovedy ways, across the disk H, or other stationary bearing, while the other two arms will fit into recesses in the circulating cog-wheel F, or the circulating plate f, when one is interposed.

It will be seen that the sliding ring or cross-arm which controls the movement of the circulating wheel, has two independent sliding bearings on opposite sides of the revolving shaft, and does not rub against or come in contact with any part of the revolving mechanism.

Having thus fully described my invention, and its mode of operation,

What I claim as new, and desire to secure by Letters Patent, is v 1. In combination with the inner circulating cogwheel, actuated by an eccentric or crank, as described, and the outer revolving cog-wheel, a sliding ring or cross-arm, having independent sliding hearings on opposite sides, and sliding bearings at rightangles therewith, for the circulating wheel or plate, substantially as herein described. l

2. In combination with the circulating cog-wheel, the circulating plate, with an adjustable clutch to attach and detach said plate to and from the circulating wheel, substantially as and for the purpose set forth.

'3. In combination with'the 'circulating and revolving cog-wheels and sliding ring or cross-arm, the revolving shaft B, the hollow stationary shaft C, and the stationary disk H, with sliding bearings thereon for the ring or cross-arm, substantially as described.

In witness whereof, I have hereunto subscribed my name, this 28th day of August, 1869.

ADDISON G. WA'IERHOUSE.v
