ANTIFRICTIONAL HANK FOR SAILS.

SPECIFICATION forming part of Letters Patent No. 601,002, dated March 22, 1898.

Application filed August 6, l 8 9 7.

.To all whom it mag concern:

Be it known that I, J OHN S. JENNINGS, a citizen of the United States, residing in the city and county of San Francisco, State of California, have invented an Improvement.

adapted to be raised and lowered upon a rope or stay-such as jibs, staysails, and others of a like character.

The invention consists in details of construction, which will be more fully explained by reference to the accompanying drawings,

' in which-- lowered upon a rope which is termed a stay are usually connected therewith by means of a ring or loop, technically called a Fhank, which is adapted to slide'upon the stay and has means by which the edge of the sail is attached to it to form a permanent connection. This device is objectionable, first, because of the friction, which is always great, and when the sail is partially filled, so as to drag to one side, it makes it almost impossible to hoist the sail. It is also objectionable on account of the wear which takes place between the stay and the. hank, and as these stays are usually made of wire rope they soon become abraded or cut, so that they must be renewed, or in some cases the hanks themselves will be worn through,

My invention comprehends the employment Serial No. 647,309. (No model.)

as to allow ample room for the passage of the stay B, and at the lower end they are'united either permanently or they may be so united.

as to be separable.

When permanently united, as shown in Fig. 1, the frame 0 is cast in a single piece and holes are made through the sides to receive a the bolt upon which the pulley A is journaled.

The lower end of the yoke has a concaved channel formed in it, as shown at c, which is adapted to receive the bolt-rope D, this rope being secured along to the upper edge of the sail in the usual manner. This bolt-rope is then attached to the yoke O by what are technically known as seizings or small cords E, which are passed through holes or eyelets F, made at intervals in the edge of the sail, the seizings passing around the lower part of the yoke O. This lower portion is divided by an upwardly-projecting lug or spur c leaving two spaces, one upon each side of it, through which the seizings pass.

- In order to conveniently attach or detach the sail, I prefer to make the yoke O in two parts. The pulley or rollerA is journaled at the upper end, the screw-bolt passing through the two sides of the yoke at this endand forming a connection, While at a point just above the lower end, where the bolt-rope lies, the lug c is made in two parts, which lie against each other and which are secured together by a screwbolt or pin G, passing through the sides of the yoke O and through the lug 0 thus binding the whole firmly together. When it is desired to attach or remove the sail, it is only necessary to remove the two screw-bolts and the parts of the hank will be separable, so that they can be-removed from the stay without disturbing the latter.

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

A device for detachably conhecting sails with the stay upon which they are adaptedsaid lugs and the sides of the yoke whereby this portion is united together and channels formed for the seizings by which the sail is attached to the yoke, a concaved roller adapted to travel upon the stay and a journal-pin passing loosely therethrough so as to unite the upper ends of the yoke together.

In witness whereof I have hereunto set my hand.

JOHN S. JENNINGS.
