OAR LOCK Filed July 6, 1940 l 2 Sheets-Sheet 2 In ventorv Bcf/,4,90 J 62mm/vo off' A torney Patented Mar. 30, 1943 UNITED STATES PATENTD OFFICE 2 Claims.

This invention relates to an oar lock, the general object of the invention being to provide means whereby the oar has a clamp attached thereto which rotates about a vertical pivot with the vertical pivot means capable of rotating about a horizontal pivot so that the oar can readily assume a great many different positions during the rowing operation so as to facilitate movement of the oar by the rower.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure 1 is a fragmentary top plan view of a portion of a boat with the improved oar lock attached thereto.

Figure 2 is a vertical sectional view through parts of Figure 1 and parts in elevation.

Figure 3 is a section on the line 3-3 of Figure 2.

Figure 4 is a view of one of the sections of the clamping member for the oar.

Figure 5 is a section on the line 5-5 of Figure 2.

In these views the numeral I indicates an angle shaped mem-ber which fits over a portion of the top edge of a boat and is fastened thereto 'by the bolts 2. The top portion of this member I is formed with an elongated sleeve 3 which extends longitudinally of the boat and is arranged above a side portion thereof. A shank 4 passes through the sleeve and is held therein by a nut 5 and a cotter pin 6 and an elbow-shaped member l connects this shank 4 with a vertical shank 8, the parts 4, 'I and 8 being integrally connected to:- gether or formed in one piece. A sleeve 9 rotatably fits over the shank 8 and has. one half of a clamp formed therewith as shown at I0. This clamp section is of substantially semi-circular shape t receive portions o-f an oar A. The other section or half of the clamp is shown at I I and the two sections are provided with upper and lower anges I2 which are fastened together by the bolts I3. The section II has internal ribs I4 therein for increasing the gripping action of the clamp on the oar. (I,

As will lbe seen the member 'I forms a lower shoulder on which the sleeve 9 rests and its other end forms another shoulder which abuts the sleeve 3 when the bolt 5 is tightened. Of course, the shank 4 must rotate in the sleeve 3 and the sleeve 9 must rotate on the shank 8 so that the oar can move to the various positions during the rowing operation and thus facilitate handling of the oar by the rower. A port 3 is formed in the sleeve 3 .so that the shank 4 can be lubricated.

In order to prevent the member composed of the parts 4, 'I and 8 from moving to a position where the sleeve 9 can slide off of the part 8, I make an arcuate groove or slot 3" in the lower part of that end of the sleeve 3 which abuts the elbow I and an arcuate projection 'I' is formed on the adjacent end of the elbow l for fitting in the groove or slot. The projection I and the slot 3" are so formed that the elbow can rock to a certain extent before the edges of the projection I will strike the end walls of the slot or groove 3', as shown in Figure 5 but the elbow cannot move to a suflicient extent `to place the part 8 in position where the sleeve 9 will slide therefrom.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts provided that such changes fall within the scope of the appended claims.

Having described the invention, what is claimed as new is:

l. An oar lock of the class described com-prising a bracket for attachment to a part of a boat, a horizontally arranged sleeve connected with the bracket, a clamp for connecting with a part of an oar, a vertical sleeve connected with the clamp and an angle-shaped member including a horizontal shank rotatably arranged in the sleeve of the bracket and a vertical shank rotatably arranged in the sleeve of the clamp, and means for limiting rotary movement of the horizontal shank to prevent the vertical shank from moving to a horizontal position said means including a slot and tongue connection between the sleeve of the bracket and a part of the angle-shaped member.

2. In an oar lock, an angle bracket for attachment to the gunwale of a boat, a clamp for embracing an oar shank, and means to mount said clamp on said bracket comprising a sleeve on said bracket extending parallel therewith, a pintle extending through said sleeve, an enlarged elbow on one end of the pintle having an end abutting one end of the sleeve, a second pintle extending from the other end of said elbow and at a right angle to the pintle rst mentioned, a socket on said clamp sleeved over the second pintle, coacting devices on the first-mentioned sleeve and elbow interlocking to limit rotation of the first-mentioned pintle in said sleeve, and a nut on the other end of the rst mentioned pintle bearing *against said sleeve to maintain said devices interlocked.
