' OAR-LOCK.

Specification of Letters Patent. f

Application filed October 29, 1910. Serial No. 589,727.

and useful Improvements in Oar-Locks, of

\ which the following is a specification, referen'ce being had to the accompanying drawlngs.

' This invention relates to improvements in oar locks, the object of the invention \being to provide an improved device of this char acter which may be readily attached to the gunwale of a boat and which serves to pivotally mount the oar lock for universal angular movement so as to permit the free and correct use of the oar in rowing, and which will also serve to prevent the casual unshipping of the car.

' With the above and other objects in View, my invention consists in the construction, combination and arrangement of devices hereinafter described and claimed.

In the accompanying drawings -Figure 1 is a perspective view of an oar lock constructed in accordance with my invention.

Fig. 2 is partly an elevation and partly a sectional view of the same.

y In the embodiment of my invention, I provide a base or yoke 1, which comprises a pair of crossed arms 2, 9 and a boss 10,

which rises from the base at the point of;

intersection of the said crossed arms. The

I arm 9 is for disposition longitudinally of and to bear on the upper side of the gunwale of a boat. The arm 2 is to extend transversely across the gunwale, and is provided at its ends with depending jaws 3, 4 to bear respectively on the outer and inner sides of the gunwale. The jaw 4: is provided with a transverse screw threaded opening in which operates a screw 5. Said screw has a head 6 whereby it may be manually turned and is provided at its inner end with a foot 7 to bear against the inner side of the body. The foot is connected to the inner end of the screw, by a ball and socket joint,

the foot having a socket therein, and the screw being provided-with a globular end .8, which operates in the socket. Through the center of the boss, and the center of the yoke extends a vertical opening 11, the lower end Ofi which is counter-bored as at 12, to provide an annular circumferential shouldef 13. A vertical pin 14 is mounted in the Patented July 4,1911;

ring 16 comprises'a lower semi-circular" sec tion 17 and an upper semi-circular sectlon 18, the sald-sections being respectively provided with oppositely projecting arms 19.,

20, which arms are detachably and adjustably connected together by means of bolts on other suitable devices 21 so that the upp'erf section of the clamping ring may be 'adjusted toward or from the lower section thereof to enable an oar to be placed in and detached from the said clamping ring, the sections of the ring,'when the oaris in place therein, being clamped on opposite sides of the oar, the latter having an annular recess or groove 22, indicated in Fig. 2 of the drawing, for engagement by the sections of the clamping ring, said recess enabling the oar to be turned in the clamping-ring as may be required in rowing. The lower section of the clamping ring is also provided .with a pair of depending spaced arms 23- which are disposed on opposite sides of the upper portion of the pin 14 and are connected thereto by a pivot bolt 24 which passes through alined openings in said arms and in said pin, the said pivot bolt and arms connecting the clamping ring to the said pin for verticalangular movement, and the said pin by reason of its being swivelly mounted in the base enabling the clamping ring to be turned angularly, as may be desired in rowmg. a a It will be understood that my improved oar look, while enabling the oar to be freely turned both axially and angularly, as is required in rowing, and while permitting free movement of the oar, effectually prevents the same from becoming unshipped and lost overboard. Moreover, my-improved oar lock may be readily attached to and removed from the gnnwale of the boat at will.

Having thus described my invention, what I claim is 1. The herein described oar lock compris ing a base member to bear on and provided with means to secure the same to the gunwale of a boat, said base member having a Vertical opening provided with a counterbore at its lower end, a pin mounted in saiding an enlarged head atits lower end in the ing ring to the pin for angular movement in a verticalplane, the pin by reason of its axial Connection with the base member also adapting the clamping ring for angpl'ar movement in a horizontal plane, and connecting the clamping ring to the base member against casual detachment of the clampmg ring. p

' 2. The herein. described oar look comprising abasemember to bear on the gunwale of a boat, and provided with crossed arms,

and a boss rising from the basememberat the point of intersection of the arms, one of the armsbeing provided at its ends with depending jaws to bear on opposite sides of the gunwale, one of said jaws having a clamping screw and the said base member and boss larged head disposed in the counter-bore,

and an oar clamping ring provided at its lower side with a pair of depending arms disposed on opposite sides of the upper por t-ion of the pin, and'a pivot element passing through said arms and pin and connecting the clamping ring to the pin for angular movement in a. vertical plane, the pin by reason of its axial connection with the base member also adapting the clamping ring for angular movement in a horizontal plane.

In testimony whereof I hereunto allix my signature in the presence of two witnesses.
