UNITED STATES GEORGE L. 'FERB-IS, OF
T a A town TEN omen-1.
can LOCK.
Application filed February 4, 1924. Seria1INo. 690,540.
To all whom it may concern:
Be it known that I, Gnonen' L. Frmnrs, a citizen of the. United States, residing at lVellston, inthe county of Jackson and State of Ohio, have invented a new' anduseful Oar Lock, of which the following is a specification. I
This invention relates to an oar lock, one of its objects being to provide a simple, durable and efficient device of this character which can be adjusted quickly to desired position on the gunwale of a boat and there held securely while the device is in use. Another object is to provide a structure of this character which is cheap to manufacture and will not readily get out of order. With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein described may be made within the scope of what is claimed without departing from the spirit of the invention.
In the accompanying drawings the preferred form of the invention has been shown.
In said drawings Figure 1 is a side elevation of the oar lock viewed from the inside of a boat, a portion of the boat structure being shown by broken lines.
Fig. 2 is a section on line 22, Fig. 1.
Fig. 3 is an elevation of the outer side of the oar lock.
Fig. 4 is a plan view.
Referring to the figures by characters of reference 1 designates a plate constituting the outer member or jaw of the oar lock, the same being formed at its lower edge with an inwardly extending flange 2 and, at an intermediate point, with a longitudinal reinforcing rib 3. The upper portion of the plate is oflset inwardly at an acute angle as shown at 'to provide a shoulder 5 and extending toward each other from the ends of this shoulder are lugs 6 spaced from the offset portion 4. An outstanding enlargement 7 is formed on the upper portion of the outer side of plate 1 and is provided with a cylindrical opening 8 extending therethrough at an acute angle to the plateor jaw 1. This opening is adapted to receive the stem of the oar engaging neck ordinarily provided.
. The other member of the oar lock comprises a relatively narrow strip, or plate 9 the lower end of which has an inwardly extending flange 10. A longitudinal reinforcing rib 11 is formed on the outer or exposed surface of this jaw and is extended along the offset upper portion 12 of the jaw which is disposed at an obtuse angle as shown. The upper portion of the rib carried by this olfset portion is enlarged-as shown at 13 and extending through this enlargement and through the upper portion of the plate or jaw 9 is a threaded opening 14 in which is mounted a set screw 15. This set screw has a head 16 at its outer end and mounted on the set screw between the head 16 and the plate or jaw 9 is a lock nut 17 In using this device the set screw 15 is loosened so that the plate 9 can be withdrawn from back of the lugs 6. The plates, 1 and 9 are then placed at opposite sides of the gunwale G of the boat so that the flanges 2 and will project under the gunwale or else will bite into opposed faces thereof. By means of a screw driver or the like the set screw is forced against the upper portion of the offset 4, thus causing the lower ends of the plates 1 and 9 to swing toward each other, the points of contact between the plate 9 and the lugs 6 constituting the fulcrum. Obviously, therefore, the gunwale will be clamped tightly between thejaws or plates. After the parts have thus been tightened the lock nut 17 can be screwed against the enlargement 13 of rib 11, thereby holding the parts securely in position to which they have been moved. The structure can then be used like an ordinary oar lock.
What is claimed is 1. An oar lock including opposed jaws, means extending from one of the jaws for embracing the other jaw, adjustable means carried by one of the jaws for engaging the opposed jaw to tilt the jaws toward each other and hold them against relative movement, there being an opening within one of the jaws for the reception of the stem of an oar engaging yoke.
2. An oar lock including opposed jaws, one of said jaws having an enlargement provided with an opening, means upon one of the jaws for'embracing the other jaw to WELLSTON, OHIO, ASSIGNOR TO THE WELLSTO'N METAL'PROD- UCTS CO'MPALMY, OF WELLSTON, OHIO. f
provide a pivotal and sliding connection between th j ws, djus e means arr by one of the jaws and movable against the other jaw to tilt them relative to each other to clamp upon a structure inserted between the jaws.
3. An oar lock including opposed jaws, one of said jaws having an enlargement provided with an opening, means upon one of the jaws for embracing the other vjaw to provide a connection between the jaws, adjustable means carried by one of the jaws and movable against the other jaw to shift them relative to each other to clamp upon a structure inserted between the jaws, and locking means carried by the adjusting means.
4; The combination with opposed jaws for gripping the gunwale of aboat and flanges extending therefrom, spaced lugs upon one of the jaws for embracing the opposed jaw and an adjusting screwcarried by one of the jaws for engaging the opposed jaw to shift the jaws angularly relative to each other.
In testimony that I claim the foregoing as my own I have hereto af Xed'my signature in the presence of two witnesses.
