Be it known that I, CHARLES NORMAN, a

' citizen of theUnited States, residing at Fran kfort, in the county of Benzie and State of 7 Michigan, have invented a new and Improved oar lock, and Fig. 2 a front elevation of the same.

Fig. 1, shows the row lock complete on section of oar. It consists of two bands, B, a ring a, and ashank twith an-open head. Two

. bands are used to secure two difierentlengths of car handles, by changing the ring a from one .band B to the other. The bands Bare in halves, and close around the oar by a beveled lap through which the screws pass, securing them to the oar. A groove 7, is out. into each band B and, around its outer circumference inwhich the ring a fits and runs.

Fig. 2 shows front view of ring a, closed on band B, dotted line showing ring a as when open. The ring a is in halves, hinged at the top by a bolt 1, to which a latch 2 is riveted, dotted lines showing latch 2 as when raised.

in a bolt 3, which passes through the head of the shank 4 far enough to allow the other half.

to close upon it, where it is held in position by a pin 5, which passes through both ring a and bolt 3.

The bolt 3 rotating in the shank 4, gives the oar the required vertical motion.

. Having fully described my invention,what I claim, and desire to secure by Letters Patent, is

1. An oar lock having a pintle andthole ring hinged thereon by suitable lugs, said ring being divided into two hinged sections, the lug on one of ,Which is perforated for the reception of a key to lock the same in engagement with the hinge bolt of the pintle.

v r 2. A pintle havinga thole ring thereon, said ring being composed of diametrically divided hinged sections, having lugs on their free ends for engaging with the pintle, and a latch on one of the sections, in combination with a grooved collar attached to the oar and having a recess therein for receiving the latch and locking the ring to the oar.
