3-Claims.

1 ,Myinvention relates to "improvements in boat oar locks of the type in which the oar is removably-and adjustablyiclamped in a sleeve pivoted on a horizontal axis on a bracket which in turn is pivoted for movement on both vertical and horizontal axes relative-to its means of support on the gunwale of the boat, theprimaryobiect of my invention being to provide an oar lock of the character indicated affording simplicity and mechanical efficiency construction whereby the oarassociated therewith can be manipulated with unusual ease in a variety of positions -of the oar without binding in the lock, and without risk of the oar becoming displaced or lost from the lock.

Another important object of my invention is to provide an oar lock of the character indicated above in which readily manipulable means is provided to lock said bracket on its horizontal pivotal axis in a vertical position, so as to prevent when desired, pivoting of the bracket at the beginning and at the end of the stroke of the oar, as in feathering the oar.

Other important objects and advantages of my invention will be apparent from the following description and the drawing appended thereto, wherein for purposes of illustration only, a preferred embodiment of my invention is set forth in detail.

In the drawing:

Figure 1 is an end elevation of my improved oar lock.

Figure 2 is a fragmentary elevation of the outer side of said oar lock.

Figure 3 is a top plan view of the multiple socket frame.

Referring in detail to the drawing, the numeral 5 generally designates the elongated multiple socket frame consisting of the depending vertical plate 6 provided with screw or bolt holes I at intervals along its length, and the horizontal socket carrying plate 8 which at intervals along its length has depending therefrom the sockets 9 which are substantially cylindrical in shape with diametrically opposed ribs in projecting therefrom.

The sockets 9 are formed with substantially cylindrical bores II which have diametrically opposed grooves I2, the bores and the grooves opening through the lower ends of the sockets and through the frame plate as indicated at l3. Screw or bolt holes M are provided in the socket carrying plate 8 at intervals along the outer edge 55 of the plate 8 and in line with the socket openings I3, and said outer edge may 2 be curvedly indented as indicated at Itbetween the sockets to afford maximumfreedom ofaction of the oar (not shown). The vertical frame plate -6-is adapted to be screwed orbolted 'to themward side of the gunwale or. side of the boat (not shown) and the horizontal socket plate-to the top of the gunwale or side of the boat, or if desired, to the stern of the boat when :the: oar

.socketrrequiring the lugs I3 to slide downwardly in the grooves l2 until they emerge below the lower end of the socket, when the pin can be turned to position the lugs l8 to act as stops against the lower end of the socket, preventing accidental removal of the pin from the socket.

Constituting the bracket of the car lock, the upper part of the pin I! has an annular shoulder l9 to bear upon the upper surface of the upper frame plate 8 and a fan-shaped, flat-sided boss 20 thereabove, against whose opposite sides bear the depending fan-shaped bifurcations 2| of U- shaped fitting 22. A removable horizontal pivot pin 23 traverses the lower ends of the bifurcations 2! and the lower part of the boss 20 to enable the fitting to pivot so as to permit the oar to be freely feathered at the beginning and at the end of a stroke. In order to lock the fitting 22 against such pivoting, when desired, a removable locking pin 24 traverses the bifurcations 2| and the upper part of the boss 20 at a point above the pivot pin 23, to hold the fitting in vertical or perpendicular fixed position, the locking pin being easily drawn when the mentioned pivoting of the fitting 22 is desired.

A horizontal pivot 25 extends between the upright arms 26 of the fitting 22 and traverses a laterally elongated lug 21 depending from the car clamping sleeve 28 substantially midway between its ends.

The oar clamping sleeve 28 comprises the lower half 29, with which the lug 21 is integral, and the upper half 30, the said halves having cooperating clamping ears 3|, 3| and 32, 32, respectively in which are used pairs of longitudinal spaced studs 33. It will be noted that the said halves are tapered so as to form a slightly outwardly tapered cylinder for reception of the shaft of the car (not shown, the bore of which can be adjusted as to diameter and as to taper, by tightening and loosening the studs 33, so as to conformably clamp the car shaft against longitudinal movement relative to the sleeve 28 at any desired point along the oar shaft; or so as to loosely conform to the diameter and taper, if any, of the oar shaft, 50 as to permit a certain amount of longitudinal shifting of the oar shaft in the sleeve, when desired.

It is obvious that an oar associated with my look as above described cannot accidentally become detached and lost even when control of the oar is lost in rough water; and that the oar lock with oar attached can be easily and quickly shifted to any one of the sockets 9 when desired.

I claim:

1. A boat oar lock comprising a vertical socket adapted to be mounted on a boat, a pin turning in and rising above said socket, a flat-sided lug rising from the upper end of said pin, a pair of plate-like elements disposed on opposite sides of said lug, a pivot traversing said elements and said lug, a U-shaped element joining the upper ends of said plate-like elements, a pivot extending between the legs of said U-shaped element, and an ear shaft accommodating sleeve having a depending portion journaled on the last mentioned pivot.

2. A boat oar lock comprising a vertical socket, a vertical pin supportably journaled in said socket and having a fiat-sided lug rising from its upper end, an inverted U-shaped element having platelike legs receiving said lug therebetween, a horizontal pivot traversing said legs and said lug, ears rising from opposite ends of said inverted U-shape, a second horizontal pivot arranged at right angles to the first mentioned pivot and extending between said ears, and an oar shaft accommodating sleeve having a depending portion journaled on said second pivot between said ears.

3. A boat oar lock comprising a vertical socket adapted to be mounted on a boat, a pin turning in and rising above said socket, a flat-sided lug rising from the upper end of said pin, a pair of plate-like elements disposed on opposite sides of said lug, a pivot traversing said elements and said lug, a U-shaped element joining the upper ends of said plate-like elements, a pivot extending between the legs of said U-shaped element, and an oar shaft accommodating sleeve having a depending portion journaled on the last mentioned pivot, and a removable locking pin positioned on one side of said first mentioned pivot and passing through said plate-like elements and said flat-sided lug through openings provided therein, for locking said plate-like elements against pivoting on said first mentioned pivot.
