,Be it known that LAL RED P iii-insulin, a

citizen oi the United States, residing at'Iron tion.

This invention relates to shoulders for oar locks, and the primary Object of the in.

vention is the provision or an improved oar shoulder, so constructed as to strengthen the oar and prevent the weakening of the same by theruse of a relatively long fastening element now generally employed in securing oar lock shoulders in place.

Another object of the invention is, to provide an improved oar lock shoulder so con 'structed as to permit the ready placing thereof in position on an arm and to eliminate the use of long fastening elements which tend to weaken the oar.

A further object of the invention is the provision of an improved oar: lock shoulder having a relatively long wear sleeve formed thereon so as to by the oar lock. V

A still further object of the invention is to provide an improved oar lock shoulder of the above character which is durable and efficient in use, one thatis simple and easy to manufacture, and one which can be placed. upon the market at a reasonable cost.

Other objects of the invention will appear in the following detailed description taken'in connection with the accompanying drawing, forming apart of this specifica-.

tion, and in which drawing: 7

of the ordinary or any preferred configura i tlon havlng the improved oar lock shoulder The sleeve portion C: includes a hollow cylindrical body '10 slit longitudinally as at 11, to permit the ready placing'of the device on the oar; The body 10 is Pl'OVldQClTOli each side of theslit portion 11 with openings 12, for the reception of relatively small fastening elements, such as tacks or the like 13, which are adapted to hold the split body in contracted position on the oar'A. body 10 forms the wear portion for the oar an? is adapted to be engaged by the oar lock an lock. v g r "The flange B constitutes the shoulder proper and is adapted to engage the oar look (not shown) tolimit the outward movement of the oar 1n the lock and to prevent the dripping of water on the hands of the oars- .men from the blade of the ear when the oars are in a raised position. The flange D includes an annular body 14: formed on the inner end of the cylindrical body 10 and is provided with a diagonal slit. 1:) the inner end of which communicates with the split portion 11 of the body 10. The diagonal slit 15 permits the annular member 14 to be flexed, to facilitate the insertion of the device B on the oar. By extending the slit 15 diagonally the same forms overlapping portions 16 and 17 and the overlapping portions are provided with alined openings. 18. 20 are adapted to be inserted in the openings and into the oarA. 1

The device B may be made of anypreferred material such asialuminum, hard fiber, for leather. When the same is'constructed of aluminum or hard fiber, the cost of the device is very slight.

In Fig. 3 isillustrated a section through thefiange B when the device is constructed of metal and it can be seen that in this form the flange B is formed integral with the body 10.

hen the device is formed from leather, the flange is preferablylaminated and made thus prevent damage to the oar by said Suitable fastening elements in a plurality of superposed sections 21, a

which can be secured together in any preferred manner.

From the foregoing description itjcan be seen that an improved car look is provided of The 70 l exceptionally simple and durable oliaraiiter which will permit the easy and convenient placing thereof on the arm, and not necessi; I

ing points located over a relatively large area of the car body. 7

Changes in details may be made Without departing from the spirit or scope of my invention, but;

I claim:

1. An oar-look shoulderincluding an annular body having a diagonal slit therein providing overlapping portions; and fasten ing elements arranged to extend through the overlapping portions and into an oar.

2. An oar lock shoulder including a longitudinally slit cy indrieal body, an annular shoulder formed the body, said shoulder having a diagonal slit communicating with the longitudinal slitin the body, and fastening elements arranged to extend through "thelongitudinal body on. each side of the slit portion thereof and into an oar, and relatively long fastenlng elements arranged to extend througlifthe overlapping portlons of the annular shoulder formed by a diagonal slit and into the oar.

3. An oar lock shoulder comprising a cylindrical body formed of flexible inaterial, an annular shoulder formed on one end of the body, said body having a longitudinally extending slit extending from one end of the same to the other and means for holding the body against flexing and on an oar.
