' OABLOCK.

vAmilication filed September 7, 1926. Serial No. 134,004.

the lock and around the oar shaft so that,

when the oar is in an operative position, all liability of the bushing sections being displaced fromthe oar lock is obviated.

It is another and very important object of the invention to provide a bushing for oar locks consisting of two substantially emi-spheroidal sections which are insertable in the lock to allow a free and easy motion therein during the rowing process.

It is a further general object of the invention to provide a device of this nature which is very simple in its construction, may be in expensively manufactured, and is designed for use in connection with the ordinaryform of row-boats now in use.

With the above and other objects in view, my invention consists of a novel construction, combination and arrangement of parts hereinafter more fully described, claimed,

and illustrated in the accompanying drawings, in which:

Figure 1 is an ,end elevation of the voar lock embodying the features of my invention,

Figure 2 is a side elevation thereof, Figure 3 is a vertical section therethrough, Figure 4 is a top plan view thereof. Referring to the drawing in detail, it will be seen that 5 designates an oar lock of the open type having oppositely bowed arms 6 spaced apart at their upper ends. With these arms, the central pin or shank 6 is integrally formed for engagement in the sockets on :the gunwale of the boat. The arms 6 are recessed or dished at their inner sides as indicated at 7.

The improved wire bushing consists of a pair of castings each of which has a body portion 8 and semi-cylindrical ends 9. The body portion 8 is of asubstantial semispheroidal formation having flanges 5 as is indicated at 10. These sections are attached about the oar shaft ll. by means of screws 12 thereby, forming cylindrical endsand a substantially spheroidal center. Thus the bushing may be inserted in the oar look as is indicated at Fig. 2 and then turned so as to dispose the bodies in the dished out sides 7 of the arms 6. When in this position, as is clearly shown inFig. 3 of the drawings, 1t

WillfbG seen that the bushing is locked in the oar lock and gives two bearing surfaces which are sufliciently free to give the'sculling motion to rowing and yet to prevent.

the oar from moving either perpendicularly orhorizontally until the oai is turned with the fiat side 10 of the bushings in a vertical position.

It is thought that the construction, operation, utility, and advantages of my inven tion will now be clearly understood by those skilled in this art without a more detailed description thereof. The present embodiment of the invention has been disclosed in detail merely by way of example, since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description. It is apparent that changes in thedetails of construction, and in thecombination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.

Having thus described my invention what I claim as new is 1. In combination, an oar bushing including a pair of sections each comprising a substantially'semi-spheroidal body having semicylindrical ends, each body having a flattened side, and anoar lock including a pair of spaced parallel arms with their inner sides dished out. g

2. In combination, an oar bushing including a pair of sections each comprising a substantially semi-spheroidal body having semicylindrical ends, each, body having a fiattened side, and an oar lock including a pair of spaced parallel arms with their inner sides dished out,..and means for attaching the sections to an oar shaft.

3. A device of the class described, including, in combination, an oar shaft bushing including a substantially semi-spheroidal body having oppositely disposed flattened sides and cylindrical ends, and an oar lock for receiving the bushing including a pair of spaced parallel arms having dished inner sides.

In testimony whereof I affix my signature.
