OAR LOCK Filed June 18, 1932 Patented Jan. 3, 1933 UNITED STATES PETER J. STARTZ, F MANITOWISH, WISCONSIN OAR LOCK Application filed June 18,

This invention relates to oar locks and has for an important object thereof the provision of a means used in combination with a conventional oar lock whereby the oar can be either firmly or loosely held relative to the car look.

Another object of this invention is to provide an oar supporting means which can be mounted on a boat so that the oar can be adjusted either inwardly or outwardly of the boat to suit the particular desires of the user.

A further object of this invention is to provide a device of this kind which is errceedingly simple in construction so that it can be readily and cheaply manufactured.

The above and various other objects and advantages of this invention will in part be described and in part be understood from the following detailed descriptlon of the present preferred embodiment, the same being illustrated in the accompanying drawing, wherein Figure l is a detail front elevatlon partly in section of a device constructed according to the preferred embodiment of this 1nvention.

Figure 2 is a vertical section partly in side elevation of the device.

Figure 3 is a detail perspective view of the spacing member used in connectlon with the oar gauging member.

Referring to the drawing wherein like numerals of reference designate corresponding parts throughout the several views, the numeral 10 designates generally an oar loclr having a substantially U-shaped upper end portion 11 and a stem 12 provided with an annular groove 13 adjacent the lower end thereof, the stem being adapted to be removably mounted in a socket provided in the side of a boat.

The car look 10 is provided with a split oar clamping member 14, which comprises a substantially cylindrical body 15 having a pair of spaced arms 16 which are adjusted relative to each other by means of screws 17. A substantially U-shaped spacing member 18 is disposed between the clamping arms 16 and this 0 spacing member 18 is provided with holes 19 1932. Serial No. 618,043.

through the bight or closed end thereof and also with holes 20 through the parallel legs so that this spacing member 18 can be turned so that the parallel legs can be positioned either in parallel relation or in transverse relation to the clamping arms 16 of the car engaging member 1 1. A pair of pintles or trunnions 21 are secured one on each side of the oar engaging member 14 and positioned in axial alinement one with the other and these pintles 21 are rotatably positioned in the parallel legs of the U-shaped member 11 of the oar look.

In the use and operation of this device, the oar lock 10 having the oar engaging member 14 swingably mounted thereon is adapted to be disposed in a conventional oar lock socket and if it is desired to hold the oar in the oar lock 10 against movement inwardly or outwardly of the boat, the screws 17 may be tightened so as to draw the clamping arms 16 toward each other, and this spacing member 18 may be disposed with the parallel legs thereof engaging the inner faces of the clamping arms 16.

In this manner, when the screws 17 are tightened, the parallel legs of the U-shaped member 18 will be compressed and thereby the cylindrical oar engaging member 15 will be made smaller and will firmly hold the oar against lateral movement with respect to the oar lock 10 while permitting rocking movement of the oar engaging member 14 relative to the car lock. here it is desired to turn the oar relative to the car look 10, as in feathering or the like, the spacing member 18 can be turned so that the parallel legs thereof will be disposed transversely of the clamping arms 16 and in this position, the oar will be rotatably carried by the sleeve or clamping member 1 1.

It is, of course, understood that various changes and modifications may be made in the details of construction and design of the above specifically described embodiment of this invention without departing from the spirit thereof, such changes and modifications being restricted only by the scope of the following claim.

What is claimed is:

r A device as set forth comprising the combination of anoar lock, a split cylindrical oar engaging member, means for swingably mounting the member on the oar lock, a pair of clamping arms formed with the member and disposed in spaced relation to each other,

a U-shaped spacing member disposed between the arms, a split cylindrical bushing Within the member and securing means engaging the arms and the spacing member to adjust the varms and coactively adjust the bushing relative to the car.

In testimony whereof I hereunto aflix my I signature. 1

PETER J STARTZ.
