Abstract

Abstract Direct-drive and gear-drive winches comprising a base for securement to a boat deck, said base having an upstanding post on which a winch drum is journaled. At the top of the drum there is a socket member adapted to receive a driving plug of a crank handle by which power is applied to the winch drum. The socket member, also journaled on the upstanding post of the base, either directly or through ring gearing drives one of a pair of ratchet wheels the other of which is connected to the drum, to effect rotation in one direction. In different embodiments, the drum and base have cooperable ratchet wheels constituting back checks. In one gear-driven embodiment of the invention the socket member and a central drive pinion have cooperable ratchet wheels, the pinion engaging idler gears on the base which in turn engage the drum through a ring gear carried thereby. The ratchet wheels provide for direct drive when the socket member is turned on one direction, and for a gear-reduction drive when the socket member is turned in the opposite direction. In another geared embodiment of the invention the socket member has a drive pinion engaging idler gears carried on a turnable spider, said idler gears engaging a ring gear of the stationary base. The turnable spider can have a direct drive of the winch drum through a pair of cooperable ratchet wheels, or it can be geared to the drum by other ratchet wheels and a second central drive pinion carried by the base. The second drive pinion engages idler gears turnably carried by the base, which latter gears in turn engage an internal ring gear on the winch drum. Turning of the socket member in one direction effects a gear drive having one specified ratio, and turning of the socket member in the opposite direction effects a gear drive to the winch drum having another ratio.

Claims Analysis

Total Claims: 15
Claim 1
Independent Claim 122 words
A winch comprising, in combination: a. a base, b. a drum part journaled on the base, c. a drive part centrally disposed in one end of the drum part and having exposed means engageable with a crank handle to receive torque therefrom, d. a ratchet comprising a pair of annuli located within the drum part and drivingly connected respectively to said parts, said annuli being disposed broadside to each other and having mutually engageable ratchet teeth, the teeth on each annulus being fixed and immovable thereon, e. a loose spline drive between one annulus and part whereby the annulus is axially movable on the part while relatively nonturning, and f. yieldable means tending to maintain the annuli and teeth thereof in engagement.
Claim 2
Dependent Claim 122 words
A winch comprising, in combination: a. a base, b. a drum part journaled on the base, c. a drive part centrally disposed in one end of the drum part and having exposed means engageable with a crank handle to receive torque therefrom, d. a ratchet comprising a pair of annuli located within the drum part and drivingly connected respectively to said parts, said annuli being disposed broadside to each other and having mutually engageable ratchet teeth, the teeth on each annulus being fixed and immovable thereon, e. a loose spline drive between one annulus and part whereby the annulus is axially movable on the part while relatively nonturning, and f. yieldable means tending to maintain the annuli and teeth thereof in engagement.
Claim 3
Dependent Claim 25 words
A winch as in claim 1, wherein: a. the spline drive includes at least one spline carried by the drum part at the inside thereof.
Claim 4
Dependent Claim 44 words
A winch as in claim 2, and further including: a. back-check means on the drum part and base, b. said back-check means including a toothed annulus disposed in the drum part and having a spline engageable with the said spline of the drum part.
Claim 5
Dependent Claim 23 words
A winch as in claim 2, and further including: a. a gear reduction drive connected between the other annulus and said drive part.
Claim 6
Dependent Claim 40 words
A winch as in claim 1, and further including: a. a unidirectional, gear-reduction drive between said drive and drum parts, b. said unidirectional drive and said ratchet being operative for driving, respectively for opposite turning movements of the drive part.
Claim 7
Dependent Claim 23 words
A winch as in claim 5, and further including: a. a gear reduction drive connected between the other annulus and said drive part.
Claim 8
Dependent Claim 61 words
A winch as in claim 3, and further including: a. a bearing bushing disposed inside of said drum part, having an outer periphery provided with a spline engaging the spline of the drum part, b. said bearing bushing being located between the back-check means and said ratchet, and having a smooth bore engaged with the base to journal the drum thereon.
Claim 9
Dependent Claim 27 words
A winch as in claim 7, wherein: a. the base comprises an upright hollow post, b. said drive part extending into and being journaled in said post.
Claim 10
Dependent Claim 52 words
A winch as in claim 8, and further including: a. a transverse wall in the hollow post of the base, and b. means rotatably securing the drive part to the hollow posT of the base, including a screw threaded into said transverse wall and passing through an aperture of the drive part.
Claim 11
Dependent Claim 65 words
A winch as in claim 1, wherein: a. the drive part and drum part have splines, b. back-check means on the drum part and base, c. said back-check means including a toothed annulus disposed in the drum part and having a spline engageable with the said spline of the drum part, d. said loose spline drive being between said one annulus and said drive part.
Claim 12
Dependent Claim 40 words
A winch as in claim 10, and further including: a. a unidirectional, gear-reduction drive between said drive and drum parts, b. said unidirectional drive and said ratchet being operative for driving, respectively for opposite turning movements of the drive part.
Claim 13
Dependent Claim 29 words
A winch as in claim 11, wherein: a. the unidirectional drive includes an annulus having ratchet teeth and having a spline engaged with the spline of the drive part.
Claim 14
Dependent Claim 43 words
A winch as in claim 6, wherein: a. the second-mentioned gear reduction drive comprises a rotary cage having a plurality of idler gears, comprising gears on the drive part and base, engaged with said idler gears, b. said cage carrying said other annulus.
Claim 15
Dependent Claim 60 words
A winch as in claim 13, wherein: a. the spline drive includes at least one spline carried by the drum part at the inside thereof, b. back-check means on the drum part and base, c. said back-check means including a toothed annulus disposed in the drum part and having a spline engageable with the said spline of the drum part.
