OARLOCK Filed Sept. 25, 1946 ALVIN J. NORMA/Y I11 rel/tar Patented Aug. 29, 1950 UNITED STATES PATENT OFFICE 1 Claim.

This invention relates to new and useful improvements in oar locks and more particularly to an oar lock having a yoke secured at its upper end for receiving and holding an oar therein.

A further important feature is to provide an oar lock of this character that is efiicient and reliable in operation, relatively inexpensive to manufacture, and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure l is a side elevational view of the invention, and

Figure 2 is an end view thereof.

Referring now to the drawings in detail, wherein, for the purpose of illustration, I have disclosed a preferred embodiment of the invention, the numeral 5 represents the stem of the oar lock which is tapered at its lower end where it is formed with a hole or perforation B, said hole being adapted to receive a cord or the like (not shown) for the purpose of retaining the stem within a conventional oar lock socket (not shown). The upper end or head I of the stem is bifurcated to receive the tongue end 8 of a Y shaped saddle 9 whose upper ends are curved to a point 9a. The saddle 9 is pivotally retained in place by a bolt and nut l9 extending through the head 7 and the tongue 8 as shown in Figure 2.

On the outer curved surfaces of saddle 9 and secured thereto in any suitable manner are a pair of ridges II which act as a reinforcing means for the saddle. A yoke I2 curved to snugly hug the periphery of an oar is seated in the upper end of saddle 9, said yoke extending well past either end of the saddle. The yoke is secured to saddle 9 in any suitable manner.

The outer ends I 3 of said yoke are circular and their uppermost ends are extended vertically to form flanges l4, connected by a pair of bolts and nuts IS. The upper portion of the yoke between its ends i3 is curved downwardly at [6 and upwardly to the center of the yoke H. The handle end of an oar (not shown) is then inserted in the yoke and is clamped therein by tightening bolts l5 which close ends IA of the yoke.

In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the construction, operation and advantages of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claim.

What I claim is:

An oar lock comprising a stem having an upper bifurcated extremity, a tongue pivoted in said bifurcations, a pair of oppositely disposed upstanding arcuate arms extending laterally from said tongue, reinforcing elements on the outer surfaces of the arms, an elongated trough shaped yoke mounted at its central portion in the arcuate arms, a pair of upstanding cooperative clamping flanges on the upper edges of the yoke at the opposite ends thereof and fasteners connecting each pair of flanges together for clamping an car in the yoke.

ALVIN J. NORMAN.
