UNITED STATES PATENT OFFICE.

JOHN F. BARRETT, OF BROOKLYN, NEW YORK.

WINDLASS.

SPECIFICATION forming part of Letters Patent No. 524,520, dated August 14, 1894.

Application filed December 5, 1892. Serial No. 454,083- (No model.)

e To @ZZ whom it may concern:

Beit known that I, JOHN F. BARRETT, a citizen of the United States, residing at Brooklyn, in the countyof Kings and State of NewYork,

have invented a new and useful Improvement in Windlasses, of which the following is a specification. Y

My invention relates to improvements in windlasses; and the objects of my improvement are to provide a windlass for the purpose, among others, of hoisting and lowering sails, &:c., on boats, vessels, &c., and keeping the halyards clear and free from fouling, thereby greatly lessening the manual labor to be exerted in hoisting and lowering sails, &c. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure I, represents a side view of the wind. lass. Fig. II, represents an end view omitting the crank. Fig. III, represents a vertical cross section on the line Fig. I. Fig. IV, represents a like section on the line y, y, Fig. I. Fig. V, represents a detail view of the crank.

Similar letters refer to similar parts throughout the several views.

The shaft A, and its standards or legs B',

B2, B2, and the bed plate C, constitute the frame work of the windlass.

The roller D is firmly secured to the shaft A so as to turn therewith, and to this roller is attached a ratchet Wheel Gengaging with the stop pawl J there is also a circumferential groove I-I in the roller D to receive a brake strap S running from the pin K on standard B over and through said groove to the pedal I on the standard B.

The roller D2 is loose and revolves indef pendently upon the shaft A, and to this roller is attached a ratchet wheel G2 engaging with a stop pawl J 2; there is also a groove I-l2 in the roller D2 to receive a brake strap S2, running from the pin K2 on the standard B2 over and through said recess H2 to the pedal I2 on standard B2. The hub G of the loose roller D2, carries a ratchet wheel F for the purpose of revolving said roller D2 in unison with' the fixed roller D and releasing it at will, which is accomplished by placing the feed pawl E, which is attached to the crank L, by means ofpins N, in said ratchet wheel. Said hub of the loose roller D2 projects through the standard B2, in which it has a bearing.

Both ends ofthe shaft A are geared and fitted to a hole or perforation M in the crank L, for the purpose of revolving the fixed roller D.

In case one man operates the windlass, he places the crank on the end of the shaft nearest standard B2 and places the pawl E in ratchet F, and turns both rollers by main force of the crank until the throat of the sail is in its proper place; he then releases loose roller D2, by removing the pawl E from the ratchet F and continues revolving fixed roller D until the peak of the sail is in its proper place,where it is held by the action of the pawl J on the ratchet wheel G.

If two men operate the windlass, the crank L, is placed on the hub of roller D2 marked Q, and another crank placed on the end of shaft A nearest standard B and both men revolve their respective cranks until the sail is in its proper place.

To lower the sail he first releases fixed roller D by removing the pawl J from the ratchet wheel G and then releases the loose roller D2,

by removing the stop pawl J2 from the ratchet G2. In case the sail runs down too fast, it can be governed by the brakes S', S2 in the grooves H and H2 of the rollers, by pressing the pedals I and I2, both of which pedals may be connected together, if desired,by means of a bar.

The bed plate C is, in practice, fastened to the deck of the boat.

The end of the crank L, has two holes or perforations; the one marked M is fitted to the squared ends of shaft A, and the one marked P, is itted to the squared ends of the hub of the loose roller D2.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

In a windlass, the combination of the shaft with squared ends, the fixed roller and loose roller thereon, the squared hub of the loose roller, the ratchet-Wheel and stop-pawl to each Wheel, all substantially as and for the purpose roller, the secondary ratchet-Wheel to the herein described. loose roller, a brake to each roller, the crank 1 with two squared holes one adapted to either JOHN F BARRErl T' 5 end of the shaft and the other adapted to said Witnesses:

hub of the loose roller, and the feed-pawl on CHARLES G. COE;

the crank, for engaging the secondary ratehetl GHAS VAHLERS.
