SAMUEL T. RICHARDSON, OF BALTIMORE, MARYLAND, ASSIGNOR TO THE RICHARDSON MANUFACTURING COMPANY, OF SAME PLACE.

WINDLASS.

SPECIFICATIONforming part oi' Letters Patent No. 311,373, dated January 27, 1885.

Application filed June 24, 1884.

To @ZZ wtom t may concern:

Be it known that I, SAMUEL T. Riel-IARD- sON, a citizen of the United States, residing at Baltimore, Maryland, have invented new and useful Improvements in Vindlasses, of which the following is a specification.

My invention relates to a lever-power windlass for use on shipboard or elsewhere.` This windlass consists of a shaft that is suitablyr mounted in a firm support, and carries at each end a windlass-barrel having ratchet-teeth for the engagementof pawls on a pair of bevelgears that are mounted loosely on the shaft near its center, and mesh with an intermediate bevel-gear that is provided with levers7 by means of which the gears are oscillated, so as to cause the pawls to alternately engage with the ratcheted Windlass-barrels, and urge them continuously forward through their rigid connection with the shaft ou which they are mounted.

The invention consists in the construction and combination of parts, hereinafter more fully set forth.

In the annexed drawings, illustrating the invention, Figure l is a top view of my improved windlass, partly in horizontal section. Fig. 2 represents a modification in the arrangement of the ratchet-teeth on the windlass-barrel. Fig. 3 is a vertical section through the bearing for the windlass-shaft.

The wiudlass-shaft A is supported centrally in a tubular bearing formed by corresponding grooves, a, in the opposing surfaces of the bearing-plates B B', that are bolted to a samsonpost, C, as shown in Figs. 1 and 3. It will be seen that the inner bearing-plate, B, is partly embedded in the post C, and the outer bearing-plate, B', is provided at top and bottom with flanges b b that lap over said inner plate, bolts c c being passed through the post and bearing-plates and secured with nuts at one end, as shown, so as to connect the parts rmly. The outer bearing'plate, B', has a tubular boss, b', that is recessed or countersunk on its inner side at b, for receiving the head of a bolt or pin, D, on which is pivoted a bevel-gear, E, having a hub, d, the end of which abuts against the boss b', as shown in 5o Fig. l.

On each end of the shaft A is mounted rig- (No model.)

idly a windlass-barrel, F, of any suitable construction, the inner end being preferably of greater diameter than the outer end. Each windlass-barrel is provided at its inner end with ratchet-teeth e, that may be arranged either on the inner face of the barrel, as shown in Fig. l, or on its circumference, as shown in Fig. 2. A pair of bevel-gears, G G, are mounted loosely on the shaft A, between the 6o wndlass-barrels F F and post or standard C. These gears mesh with the bevel-gear E, that is mounted in a plane at a' right angle, as shown in Fig. 1. The bevel-gears G G have elongated hubs f f, that abut against the ends ofthe tubular bearing a, and each gear is provided with rone or more pawls, g g, for engaging the ratchet-teeth e c on the windlassbarrel. The intermediate bevel-gear, E, is provided with sockets h h for detachable hand- 7o levers H H, by which the several gears and windlass-barrels are actuated.

It will be observed that by means of the hand-levers H H and gear E the gears G G will be made to oscillate rcciproeally, so that their respective pawls will engage alternately with the ratchet-teeth on the windlass-barrels F F, and these latter, being rigidly secured to the shaft A, will consequently rotate together with a continuous forward movement.

The ratchetteeth e can be formed on the circumference of the windlassfbarrel F, as represented in Fig. 2, or they may be arranged as an internal ratchet-gear on the inner recessed face of the barrel, as shown in Fig. l. When constructed in the manner shown in Fig. l, a series of perforations, z' t, are provided to permit the escape of water, and thus prevent its accumulation in the recessed end of the windlass-barrel when the latter is eX- 9o posed to wet weather.

Several of the devices herein shown are speciiically claimed in my application for patent led June 24, 1884, Serial No. 135,915; and hence I herein enter a disclaimer of such devices.

Having thus described my invention, what I claim is- 1. In a windlass, the combination of a shaft mounted in suitable bearings and carrying a roo barrel at each end, said barrels being provided with ratchetteeth, a pair of bevel gears mounted loosely on the shaft at the inner ends of the windlass-barrels, and carrying pawls adapted to engage with the ratchets, and an intermediate bevel-gear pivoted in a plane at right angles with the pawl-carrying gea-rs and arranged to mesh therewith, substantially as described.

2. In a windlass, the combination of the post or standard C, the bearing-plates B B', bolted thereto, one of said plates being provided with a tubular boss, b', the shaft A, the windlass-barrels F F, rigidly secured thereon and provided with ratchets e e, the bevel-gears G G, mounted loosely on the shaft at the inner ends of the barrels, and having hubsff and 15 pawls g g, and the intermedia-te bevel-gear, E, having levers H H and hub d, said gear being journuled on a pin, D, supported in the tubular boss of the bearing B', substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

SAMUEL T. RICHARDSON.
