Q CHARLES BESTMAN, OF FRIDAY HARBOR, WASHINGTON.

OAR-LOCK.

Specication of Letters Patent.

Patented Feb. 23, 1909.

Application filed June 23, 1908. Serial No. 439,930.

To all whom it may concern:

Be it known that I, CHARLns BEs'rMAN, a citizen of the United States, and a resident of Friday Harbor, in the county of San Juan and State of Washington, have invented a new and Improved Oar-Lock, of which the following is a full, clear, and eX- act description.

This invention relates to oar locks, and more particularly such as have resilient ineens for locking them at the gunwales of a oat.

The object of this invention is to provide oar locks, simple in construction and inexensive to manufacture, which have means Aor removably securing them at the gun- Wales of a boat.

A further object is to provide a device of theclass described, comprising a recessed keeper ada ted to be arranged on the gunwale of a oat, and an oar lock having a yoke and a shank, the latter being adapted to iit into the recess of the keeper, and resilient means carried by the shank for removably locking the oar lock at the keeper.

The invention consists in the construction and combination of parts to be more fully described hereinafter and particularly set forth in the claims.

Reference is to be had to the accompanying drawings forming a part of this speciiication, in which similar characters of reference indicate corresponding parts in both views.

Figure 1 is a longitudinal section of an embodiment of the invention, showing the same in position on the gunwale of a boat; and Fig. 2 is a side elevation having parts in section, and showing, in dotted outline, the resilient locking means in a retracted position.

Referring more particularly to the drawings, I provide a keeper 1 arranged in a recess 2 ofthe gunwale of a boat and having a constricted opening 3, and forming a socket. The constricted portion of the keeper forms an annular shoulder 4. Screws 5, arranged in counter-sunk openings 6, serve to secure the keeper in the recess 2. I further provide an oar lock 7 consisting of a yoke 8, of any common or preferred form, and a tapered shank 9, the latter having an annular shoulder 10 near the yoke. The shank 9 has two recesses or grooves 11 opposite to one another. Arranged within these recesses are spring members 12. The latter are normally, outwardly disposed with respect to the shank 9, and each has an oleset portion 13 adapted to engage the annular shoulder 4 of the keeper to secure the oar lock in position. The upper ends 14 of the spring members are bent upon them selves to form grips.

As shown most clearly in Fig. 1, the grooves 11 which receive the Ispring members are suitably deepened near the to of the shank for receiving the off-set portions and the ends 14, when the former are held out of engagement with the annular shoulder of the keeper.

The spring members may be secured to the shank in any desired manner, as,for instance, by having their ends 15 arranged in openings 16 ofthe shank, as shown in Fig. 1. It should be further understood that these spring members may be of any suitable form, that is, they may be either flat or round.

To place the oar lock in position, the stem is forced into the opening 3 of the keeper; the spring members, on account of their normal positions, moving into inoperative positions in the grooves 11. As however, the olf-set portions 13 of the spring members pass the shoulder 4 of the keeper, the spring members leave the grooves of the shank and the off set portions engage the annular shoulder removably to secure the oar lock in position. The annular' shoulder 10 of the shank of the oar lock engages the to of the keeper' over the opening to present a caring surface, as the oar lock is swiveled in rowing.

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

1. In a device of the class described, a keeper having a constricted opening, an oar lock consisting of a yoke and a tapered stem for engaging the keeper having oppositely arranged longitudinal grooves, and spring members in the grooves rovided with off-set portions for engaging tfie constricted openmg.

2. In a device of the class described, a keeper' adapted to be arranged on the gunwale of a boat, said keeper having an undercut opening, an oar-lock consisting of a yoke and a tapered stem, said stem having a shoulder, said stern further having grooves and being adapted to be received by the opening in said keeper, and spring members neme to this specification in the presence of Carried 1n said grooves and having ofi-set two subserlbing Witnesses.

portions near the upper ends thereof said g off-set portions being adapted to engage et A CHARLES BESTMAN' 5 the under out o ening of the keeper7 to se- TWitnesses:
