To all whom t may concern.'

.Be it known that I, sAAcFiniNcis TAY- LOR, asubyect of the King of Great Britain.,

and ireland, residing iat .5 Uplandl road, East Dulwich, London, S. Ewlngland, :have invented certain new and useful improvements in "Winches, of which'the following is a specification. i

This invention relates to winches for use in launching boats or for other purposes or generally to hoisting' gearV in which the winding barrel or barrels is or are adapted to be disengaged from the hand or power.v riving shaft and .controlled dur' operated v ing the lowering of the load by a brake drum or drums.

The invention has for its objects to yenable the lowering or raising of loads vand particularly the lowering or raising and trimming of boats to be effectedand controlled with 1 greater ease and facility than heretofore.

Vith the above objects in viewv the improved winch comprises a winch barrel or barrels with a brake drum ordrums thereon actuated through a hand or power operated countershaft geared to the barrel or barrels by spur. gearing, and worm gear adapted to tljansmit the powerto the countershaft and applied thereto in such niannen'that` lthe shaftA can be moved vlongitudinally vtn ,put

same outofgear with ,thewinch barrel `or barrels as hereinafter described.

.lVhen the winch is employed on board ship to coperate with the usual davits one winch barrelis provided for lowering or raising the boat and another for slewing theV davlt. The Winches may also be vused withv davits of the pivoted cantaliver type,A and may be worked separately `or coupled for` ease of control.

Hand and foot levers are providedtop-control the gear and brake mechanism of the winch such controlling levers being arranged on the winch framing or on an'over-l head platform or bridge.

ln the accompanying.drawings Figures 1 and 2 are side and end elevation respectively Aof a winch constructed according to this invention part of the end framing being ybroken away in Fig. 2. Fig. 3 is a side elevation. showing two winches coupled together and adaptedto be controlled from a distance, Fig. 4 is an end elevation of same, Figs. 5 and 6 illustrate the controlling levers Vand platform in-elevation and S cccatcn of Letters Patent..

barrels c Z each carrying a fixed spur vgear or lowering loads and is provided withv a brake drum gacted'upon by a brake band g1 operated by a hand leverg2 to control the lowering of the load; Ratchet wheels It 711By are alsoprovided on the ends of the winchf barrels and are engaged bypawls t' l pivoted on the winch framing" for,v holding the barrels against rotation in one direction. when required. vWorm gear illustrated in,` detail in; Fi gs. 7 and 8 is employed for transmittingY the power tol the countershaft Fart of this shaft on which a wormwheel j is mounted is inade square in cross Asection or provided 'witha feather and adapted to slide inthe worm wheel so lthat the vshaft]2 can be moved longitudinallyto put its pinion c outof gearwith the 1 winch barrel or into gear as`desired.. By

frames and is moved by an angle lever u2 pivoted in`Y a bracket ug and actuated by a By this construction the Winch barrels CZ CZ can be rotated simultaneously at the samerate by actuating one Aor both driving cranks and will wind up or pay out their ropes to a corresponding eX- tent, or they may be disconnected to pay out or wind up the ropes at dierent rates, for example, to enable a boat to be trimmed when used for lowering same.

The Winch barrels c are divided transversely by a central flange and each receives two ropes'which are wound thereon in op posite directions, such ropes being attached to a davit or other device required to be slewed or adjusted about a. vertical axis. In this case the retaining pawl t' is lifted out of engagement while the barrel is rotating and held in the disengaged position Vby a2 pivoted strut or latch 2 which is pivoted to the end of the pawl z' and which can be thrown into contact with the winch frame so as to hold the pawl in the disengaged position. In this case the various controlling devices for the brake drums and gears are shown with connections broken away but intended to lead to a controlling platform with hand and foot levers as shown in Figs. 5 and 6.

The brake bands g1 are connected by levers g2 rods g3 and bell crank levers g* with'controlling hand levers g5 pivoted at g on the bridge or platform fr while angle levers r2 arranged to operate the shafts f are connected through rods r3, angle levers r* and rods r with the upper end of a pivoted arm r6 pivotally connected with a rod 1-7 which is coupled by a sliding collar rs to the lever g5; A grip lever mounted on the lever g5 engages the collar rs and causes the connections r3 to 77 to move in unison with the lever g5 when sameis being de- For this purpose the before the brake handle is released by pressf ing the grip lever to release the collar rs and connections r3 to W controlling the shaft Y f. A foot lever y is connected in a similar manner to the hand lever g5 with the angle lever u2 which adjusts the coupling shaft t'.

What I claim and desire to secure by Let ters Patent is l. A winch comprising a pair of winch barrels, brake drums controlled by brake bands and levers, 1neans for gearing the barrels together in such manner that they can be rotated simultaneously at the same rate to wind up or pay out the ropes or disconnected to enable the barrels to be rotated at different speeds, worm gear arranged to transmit power to the winch barrels and in dependent of said means, and means for disengaging the winch barrels from the worm gear.

2. A winch of the character set forth, comprising in combination a 'winch barrel, a brake drum for said barrel, a brake band for said drum, means for winding said barrel adapted to be thrown into and out of gear, an operating bridge or platform, connections leading from said platform for op erating the brake band, and connections leading from said platform for controlling said winding means, and a releasable grip connecting said band connections with said winding means connections whereby the winding means may be thrown out of operation simultaneously with the applica-tion of the brake, but that the winding means can be thrown into operative position before the brake is released.

In testimony whereof I have affixed my signature, in presence of two witnesses.
