IVALTER MILLER, OF CLEVELAND, OHIO, ASSIGNOR TO THE GLOBE IRON )VOR-KS COMPANY, OF SAME PLACE.

STEAIVI AND CAPSTAN WINDLAPSS.

SPECIFICATION forming part of Letters Patent No. 403,435, dated May 14, 1889. Application filed December 17,1888. Serial No. 293,835. (No model.)

To all whom it may concern.-

Be it known that I, VALTER MILLER, of Cleveland, county of Cuyahoga, State of Ohio, have invented certain new and useful Improvements in Steam and Capstan Vindlasses, of which the following is a specification,

The object of my invention is to provide a compact, neat, and serviceable form of wind- Io lass for use between decks of a vessel, operated by steam or by a capstan on deck, and having all its parts readily accessible for use and repair.

My invention consists in the combination r 5 and arrangement of parts, as hereinafter described, shown in the drawings, and more fully pointed out in the claims.

In the accompanying drawings, Figure l is a plan view of my improved windlass. Fig. f2

2o is a front elevation. Fig. 3 is an end elevation. Fig. 4 is a side elevation of the central bitt or pedestal. Fig. 5 is a front elevation of the same, having' the upper portion of the hood covering the front of the worin-Wheel broken away. Fig. 6 is a separate view of the clutch mechanism on the crank-shaft. Fig. '7 is a separate view of the clutch mechanism on the auxiliary vertical shaft, and Figs. 8 to l5, inclusive, are detail views of the wild-cat and 3o mechanism operating as a clutch for seizing and releasing the same.

In the figures, A is the main bed or sole plate, having at either end the engine-cylin ders B and crank-shaft bearings C, cast in- 3 5 tegral therewith, and vertical cheeks or bitt-s I), on which the horizontal windlass-shaft E is journaled.

The windlass shaft is supplied with the usual number of wild-cats, spools, and brakes,

4o and is, furthermore, centrally supported and strengthened by bearings F in a large central bitt or pedestal, F, bolted to the sole-plate A. The engines used in this construction of windlass are of the plain slide-valve type and non-reversible. The crank-shaft G is supported in the engine-bearings C upon the rear of the sole-plate A and in bearings F2 in the rear of the main bitt F and integral therewith.

5o Between the bearings F2 in the main bitt are loosely journaled upon the shaft G the bevel-gears H, having clutch-faces, and between them, connected with the shaft G by a spline, the cylindrical double clutch I, operated by lever J, extending to the front of frame A, where it may be readily within reach of the operator.

A vertical shaft, K, supported in the three bearings F3 in the rear of the main bitt F, terminates below in the bevel-gear L, (shown 6o in dotted lines in center of Fig. 2 and in Fig.

3,) which, meshing with the bevelgears I-I on the crank-shaft, has movement communicated to it by means of the clutch I. A Worm, M, (shown in dotted lines in Fig. 3,) on shaft K meshes with the worin-wheel N on the Windlass-shaft E. The movement thus conveyed is easily reversible by means of the clutch I meshing alternately with bevel-gears H; or the Windlass-shaft may be instantly stopped by 7o placing the clutch I in the central position without stopping the engine.

Mounted upon a pedestal-bearing, O, on the top of the main bitt, is the vertical shaft O', extending to the capstan above. Itis provided, near itsV base, with the gear-Wheel O2, meshing with the loose pinion P or the vertical shaft K. This pinion has a clutch-face, P, on its upper surface, meshing with a clutch, K, on the shaft K, so that the Windlass may So be operated by means of the eapstan-shaft O independently of the engine, if desired, the clutch I on the main shaft being placed in its central position. The clutch K is raised out of connection with the pinion P by means of the pins 7o, (shown in the details in Fig. 7,) the operator grasping the pins k by the hand and raising the clutch on the shaft K. When it is desired to engage the clutch K with the pinion P, the clutch K is allowed to drop of 9o its own weight and make the engagement between them, when the Windlass is operated by the engines.

The Worin-wheel N (shown more clearly in Figs. 2 and 3) being necessarily large and eX- 95 posed, the main bitt F is so designed as to practically inclose and protect it from accident, While also remaining sufficiently rigid and strong to support the necessary journals. Figs. 3, 4, and 5 illustrate this more fully, zoo

the front of the Wheel N being covered by the arched extension F4, bolted to the main part of the bitt.

The wild-cats Q are mounted loosely on the shaft E, and are anged on their peripheries, as shown in section in Fig. 8, for the brake,

as in common use, and for accommodating the clutch mechanism, as described.

'Ihe wild-cat Q, having the overhanging iiange q on its periphery, has at intervals on the vertical face adjoining the flange and contiguous to it the raised bosses q. A disk, R, keyed to the shaft E and adjoining the wildcat, is supplied with radial guides r on its inner face, in which slide the movable dogs r', capable of engaging with the bosses or lugs q on the face of the wild-cat and imparting movement to it from the shaft E when pushed out to the end of their throw, but releasing the wild-cat when drawn in. These dogs are controlled as follows: Loosely journal'ed on the hub of the disk R is an external disk or cover, S, pierced by slots s, which are arranged in lines diverging spirally from the center of the disk outward. Bolts or pins r2 from the dogs r extend through these slots,- and rotation of the external disk causes these pins and accompanying dogs to diverge or approach, as may be necessary to catch or release the wild-cat. A short portion of the outer end of the slots is left circular to insure stability in the dogs when at their outer throw. Short radial slots are shown in the disk R, in which the pins play throughout their throw. Sockets s are supplied in the` periphery of the disk S to admit of the application of bars to rotate it `by hand. vThe clutch thus formed is extremely serviceable, compact, strong, and not liable to get out of order.

I am aware that clutches for this purpose have been invented by Potter, No. 371,853, October 18, 1887, in which radially-moving dogs are engaged by a cam-shaped flange on a separate driving-head, the whole being'open to sight, and by Moulton, No. 241,818, May 24, 1881, who employs a single disk provided with slots, in combination with bars and driv ing-gears. I do not claim the arrangement or combination of either of said devices.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. In a windlass, a detachable main bitt or pedestal, F, in two vertical and integral portions provided with horizontal bearings F and F2, vertical bearings F3 and O, and detachable guard F4, in combination with stationary bedplate A and shafts G, E, K, and O', substantially as described. Y

2. In a windlass, a detachable main bitt or pedestal, as F, in two equal vertical portions, connected and integral at their upper edges to form a bearing, O, in combination with an inclosed worm-wheel, N, and worm M, detachable guard F4, and bed-plate A, substantially as described.

3. In a windlass, a wild-cat loose on the Windlass-shaft, provided with an overhanging ilange and lugs on the interior side of said flange, a driving head or disk adjacent to the vertical face of the wild-cat and keyed to the shaft, provided with radial guides and slots, and an exterior disk loosely journaled` upon the hub of the interior disk and having slots arranged spirally to the axis of the disk, in combination with Adogs adapted to slide in the guides of the interior disk and bolts integral with the dogs passing through the radial
