ROWLOCK.

SPECIFICATION forming part of Letters Patent No. 416,239, dated. December 3, 1889.

Application filed uly 6, 1889. Serial No. 316,710. (No model.)

To all whom it may concern:

Be it known that I, GEORGE IV. ROES, of Harrison, in the county of Cumberland and State of Maine, have invented a new and useful Improvement in Rowlocks, of which the following is a specification.

This invention relates to that class of rowlocks or oar-locks in which the oar is adapted to be attached to the rowlock, and the stirrup IO or fork of the rowlock is constructed so as to be remo'vably secured to the gunwale.

The nature of the device is fully described below and illustrated in the accompanying drawings, in which a Figure 1 is a part longitudinal vertical section and part side elevation of a rowlock embodying my invention, the oar being shown in end elevation. Fig. 2 is a cross vertical section of the same, a portion of the oar being shown in side elevation.

Similar letters of reference indicate like parts.

A represents a plate adapted to be screwed or otherwise secured to the gun Wale, into which extends the tubular post A, integral with said plate, the whole forming the socket. The end of the plate is cut away or grooved at a from said end to the center to receive a sliding block B, slotted at b to receive the thumb-screw b, and provided at its inner end with a projecting shelf or tenon B, which is curved, so as to fit into an annular groove (below described) in the post which supports the stirrup of the rowlock.

O is the post which supports and is integral with the stirrup D. This post is supported in the tubular post A, is provided with an annular flange G,which rests 011 the plate B,

and with an annular groove C, into which the shelf or tenon B extends, and whereby 40 the rowlock is locked in position.

To remove the rowlock proper from the socket, loosen the screw Z), and, by pressing the thumb upon the thumb-piece or projection B, push back the slide B, thus withdrawing the tenon B from the groove 0. The stirrup D is made thick enough at its lower portion to allow of the curved slot D, and the oar E is provided with a strap E of any suitable material, which extends through said slot D and locks the oar to the rowlock proper. When the oar is removed, the rowlock is removed'also from the socket in the manner above described.

Having thus fully described my invention, What I claim, and desire to secure by Letters Patent, is

1. In arowlock, the stirrup D, provided with the groove D, whereby a strap, as E, secured to the oar, may pass through said slot, thus securin g the oar to the rowlock, substantially as and for the purpose set forth.

2. In a rowlock, the combination of the stirrup D, slotted at D, and the post 0, provided with the groove 0, all forming the rowlock proper, and the plate A, tubular post A, and slide B, provided with the tenon or shelf B and screw Z), all forming the socket, substantially as and for the purpose described.
