Specification of Lettersl Patent. Patentedct. 22,1912.

Application led'Aprl 30, 1912. Serial No. 694,064.

To all whom t may concern.'

Be it known that I, WILLIAM STEPHEN- son, a citizen of the United States of America, residing at Madison, in the county of Dane and State of Wisconsin, have invented' new and useful Improvements in Oar-Locks, of which the following is a speeiiieation.

My present invention relates to improvements in oar locks and has particular application to locks for the oars of fishing boats,

vention is not limited in its useful application to this purpose. I

In carryingout the invention, it' is my purpose to provide a lock of the type set forth whereby the oars may be manipulated with facility and convenience to propel thev boat and prevented from detaching themselves from the boat in the event of such oars being released by the operator.

. lt is also my purpose to provide an oar lock which shall embrace the` desired features of simplicity, efficiency and durability and which may be attached to .any style of oar without changing the structure of such oar.

With the above andv other objects in view, the invention consists in the construction, rombination and arrangement of parts hereinafter set forth in and falling within the scope of the appended claim.

Vln the accompanying drawing; Figure 1 is a side elevation of an oar lock constructed in accordance with the present invention,

' the same being shown applied to an oar.

Fig. 2 is a transverse sectional-view of the same, and Fig. 3 is a detail perspective View of a modified form of the-invention. Fig. flis a transverse sectional View of Fig. 3.

Similar reference characters designate lilze parts throughout the several views.

yReferring now to the accompanying drawing in detail, a boat oar is indicated at und attached to t-he body of such oar beyond 'the blade is my imprcved oar lock designated as an entirety by the letter B.

rThis oar lock, shown, embodies an attaching plate l in the form of an elongated strip and provided with aconcaved surface f" in cross section designed to coincide with the curvature of the body of the oar'so that the attaching plate and oar may present, to all intents and purposes, an integral structure, the attaching plate l being provided with spaced longitudinally arranged apertures 3 adapted to receive screws or thel like fastening devices whereby such plate may be rigidly and securely fastened to the oar. This oar lock also includes a pivot post 4t adapted to enter a socket in the gunwale of the'boat to which the Voar is applied. This. pivot post et, is pivotally connected to the,

lower surface of. the attaching plate l and in the present instance is provided with a bifurcated end portion 5 forming the spaced parallel ears 6, 6 between whichis inserted an ear 7 formed on the lower surface of the attaching plate, grooves 8, 8 being also formed in the lower surface of the attaching plate upon the opposite sides of the ear 7 to accomlnodatethe free extremities of the ears 6 of the pivot post and permit free motion between the parts, a pivot pin 9 being passed through alining apertures in the ears 6 and 7 to' secure the parts in their assembled positions.

In the modified form of the invention shown in Fig. 3, the lower surface of the attaching plate l is provided with depending parallel spaced ears 10, l0 between 'which is inserted an ear ll carried by the end l2 of the pivot post it, such cars being provided with alining apertures designed to receive a pivot pin lli, the plate 'l in this instance being preferably provided with an aperture 14 which aperture arranged between the ears if). l() so as to permit free movement of the parts and minimize friction.

From the foregoing description taken in connection with the accon'lpanying drawing,

it will be seen that l4 have provided an oar meme@ conform to the curvature of an oai' anni hevlng formed 1n its und e1 sul-face grooves spaced apart, an ear depending from said plete and connected Jthereto between the grooves therein, a pivot poet having a bifurcated end recelvlng said ezu' and having Jche .free extremities of the limbs thereof disposed Within said grooves, and a pivot pin pesse through the bifurcated end of Said pivot post and said ear. 10

In testimony whereof I eiiix my signature in presence of two Witnesses.
