' OAR-LOCK.

Specification of Letters Patent.

Application filed May 13, 1913. Serial No. M7358 V of rowing.

Another object of this invention is to provide an oar lock with gripping members which will firmly grip the oars, and at times, such as when the boat is drifting or trailing, when the oars are not in use, will prevent them from being lost. I

With the foregoing and other objects in view, this invention consistsin such novel features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings and claimed.

In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters of reference designate like or corresponding parts throughout the several views, and in which,

Figure 1 is a side elevation of the improved oar lock; and, Fig. 2 is a fragmentary view of the oar lock showing one of the crutch arms thereof in section.

In referring to the drawings by numeral, 1 designates a swivel pin which is seated within the opening in the gunwale of the row boat (not shown) and which has two arms 2 and 3 formed integral therewith and extending upwardlytherefrom forming a seat or crutch for the car look. The two arms 2 and 3 extend outwardly substantially at right angles to the swivel pin 1 for a short distance from whence they curve upwardly for substantially one-quarter of a circle, having their upper ends 4 and 5 extending parallel with the swivel pin 1. The extreme upper ends of the two arms 2 and 3 have their inner sides rounded, coming to a point as is shown at 6 in the drawings. 1

Ears 7 which are formed integral with the oar seat and extend parallel from the inner edge of the same immediately above the portion to which the swivel pin 1 is connected, have a pin 8 rigidly mounted in openings Patented Dec. 29, 1914.

9 which extend therethrough. meinit bers 10 and 11 which are segmental in shape and have their upper ends 12 curved slightly 7 outwardly as is clearly shown in the drawings are, pivotally mounted upon the pin 8. These two members 10 and 11 are constructed of metal or any suitable material and have trunnion pins 13 and 14 extending outwardly therefrom at a substantially short distance downward from the outwardly curved points or ends 12 of the same. The axes of the trunnion pins 13 and 14 are preferably in alinement or coincide, with the diametrical line of the two members 10 and 11 and extend through elongated openings 15- and 16 which are formed in the enlarged portions 17 in the portions of the arms 4 and 5 which extend parallel with the swivel pin 1. The ordinary cotter pins 18 are inserted through the outer ends of the trunnion pins 13 and 14 and prevent the pins from being drawn entirely out of the elongated openings15 and 16. Each of the trunnion pins have coil springs 19 disposed thereabout having one end of the spring engaging the outer edges of the segmental members 10 and 11 while the other end en-.

gages the innersurface of the arms 2 and 3 of the oar seat. These springs 19 tend to keep the two members 10 and 11 pressed inwardly or in a position as is shown in Fig. I

1 of the drawings, at all times, so that they will grip the oar (not shown) and prevent the same from shifting or sliding during the operation of rowing.

Themembers 10 and 11 which are the oargripping members, being pivotally mounted upon the pin 8 and resiliently held in place by means of the springs 19, will upon the operation of the oar (not shown) allow movement thereof, assuming at different periods the position that is shown in Fig. 2 of the drawings, thereby allowing a free and easy movement of the oar and also preventing the latter from shifting or becoming lost when the oars are allowed to trail and the boat to drift.

The openings 15 and 16 in the arms 2 and 3 of the oar seat are elongated in order that during the various pivotal operations of the two members 10 and 11 the trunnion pins will be allowed free movement and will not bind as would be the case if the openings were not elongated.

In practical fields, certain minor features of construction, combination and arrange- I ment of parts may necessitate alterations to which the patentee is entitled provided such alterations are comprehended Within the scope of What is claimed.

What is claimed is 1.- In an oar lock, a crutch arm having a pair of car gripping members pivotally connected thereto, means for yieldably holding said oar gripping members in engagement with an car, and means for limiting the pivotal movement of said oar gripping members.

2. In an oar lock, a swivel pin, a crutch arm formed integral with said pin, ears formed upon said crutch arm, a pin rigidly seated in said ears, members pivotally mounted upon said pin for gripping an oar and preventing the same from shifting during the operation of rowing and further to hold the oar attached to the boat when not 20 in use.

3. In an oar lock, a swivel pin, a crutch arm formed integral With said pin, mem bers for gripping an oar pivotally connected to said crutch arm, trunnion pins attached to said pivoted members and extending through elongated openings in the arms of said crutch arm, expanding coil springs mounted about said trunnion pins and engaging said pivoted members and said crutch arm for holding said pivoted members in engagement With an oar at all times.

In testimony whereof I afiix my signature in presence of two Witnesses.
