OAR-LOCK.

Application filed July 31,

To all whom it may concern:

Be it known that I, Alonzo J. SARGENT, a citizen of the United States residing at Jackson in the county of Jackson and State of lviichigan, have invented certain new and useful Improvements in Oar-Locks of which the following is a specification.

This invention relates to an improved detachable oar lock and has as one of its principal objects to provide a device of this character which may be conveniently carried about and to this end will be provided with elements which may be folded so that the device will occupy a minimum space.

The invention has as a further object in this connection to provide a device having foldabie supporting arms but wherein said arms will, when in active position, be locked against movement.

And a still further object of the invention is to provide a device which may be readily attached to or detached from the gunwale of a boat and adapted, when in position, to support an oar stirrup above the gunwale so that such stirrup will not wear against the gunwale.

Other and incidental objects will appear hereinafter.

In the drawings:

Figure 1 is a plan view showing my improved device applied to the gunwale of a boat, the gunwale being conventionally illustrated,

Fig. 2 is a perspective view showing the device detached,

Fig. 3 is a fragmentary sectional view taken on the line 3 3 of Fig. 1, and

Fig. at is a fragmentary sectional view 7 taken at substantially right angles to Fig. 3, centrally through the device.

Fig. is a fragmentary view of the top most portion of supporting arm 14.

In carrying the invention into effect, my improved device is formed with a cylindrical stirrup socket or barrel 10 from opposite sides of which project pairs of spaced lugs, the uppermost of which are indicated at 11 while the lower lugs of said pairs are indicated at 12. The uppermost lugs 11 are somewhat thicker than the lower lugs and formed in the lugs 11 are, medial alined slots 13 opening through the outer ends of the lugs and extending radially with respect to the socket 10. In this connection, it is to be observed that the socket is open at its ends. Swingingly mounted upon the socket are Specification of Letters Patent. Patqented Mal 34), 1920.

Serial 13f 0. 314,454.

standing from the uppermost of the lugs 16 are ribs 17 and removably engaging through the lugs of the socket and the lugs 16 of said arms are pivot pins 18 detachably and swingingly connecting the arms with thesocket.

Integrally formed on the socket at substantially right angles to the plane of the lugs 11 and 12 are clamping arms 19 and 20 respectively. ihese arms curve d0wn wardly and inwardly beneath the socket and formed on the inner end of the arm 19 is a laterally enlarged head 21. At its lower end, the arm 20 carries a cylindrical head 22 through which is threaded a clamp screw 23 and swiveled upon the inner end of said screw is a clamping plate'24 confronting the head 21 of the arm 19. Formed on the socket at opposite sides of the arm 19 are stop lugs 25 and formed on the lowermost of the lugs 16 of the arms 14 are stop lugs 26 adapted to coact with the lugs 25 for limiting the arms in their outward swinging movement to alined position.

It is now to be observed that the ribs 17 0f the arms 14 are adapted to engage within the slots 13 for locking the arms in alined active position extending at opposite sides of the stirrup socket 10. Consequently, the device may then, as shown in Fig. 1, be fitted upon the gunwale of a boat to engage the arms with the upper edge of said gunwale. In this figure the gunwale of a boat has been conventionally illustrated at 27. The arms will thus support the device upon the gunwale in such position that the head 21 of the arm 19 will confront the outer face of the gunwale while the plate 24 upon the clamping screw 23 will confront the inner face of the gunwale. Accordingly, the clamping screw may be operated for securely clamping the device upon the gun- Wale. The socket is adapted to carry any conventional type of oar stirrup as conventionally shown at 28 in the drawings. The shank of the stirrup is rotatably fitted through the socket in the usual manner, and

of the stirrup socket for supporting the socket spaced above the upper edge of the gunwale so that the shank of the stirrup w1ll not contact with the gunwale to wear thereagainst. Furthermore, it is to be particularly noted that since, when the arms l l are in active position they are locked against swinging movement, lateral displacement of the arms from engagement with the gunwale will be prevented. I accordingly provide a device which, as will be at once appreciated, may be readily attached to the gunwale of substantially any conventional type oi? row boat and which will provide a firm support for an oar. If desired, the arm 19 may be provided with spaced keeper lugs 30 for removably receiving, as suggested in dotted lines in Fig. 3, the needle of a fish stringer. In this way a string of fish may be allowed to trail in the water while, at the same time, being conveniently connected with the boat.

Particular attention is now directed to the fact that the arms 14 are mounted to move vertically upon the pivot pins 18;

Consequently, when the device is detached, the arms-will normally drop downwardly upon said pivot pins to disengage the lugs 17 from within the slots 13. Thus, the arms may be folded inwardly to lie along the sides of the arm 20, so that the device will occupy a minimum space and accordingly may be easily carried about. I, therefore, provide a particularly convenient type of portable oar lock.

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

1. A device of the class described including an open-ended stirrup socket, supporting arms extending downwardly from said socket and terminating below the inner end walo for supporting the inner end of the socket above the gunwale, clamping arms extending from the socket at opposite sides of the gunwale, and clamping means adjustable upon one of said arms to cooperate with the other for engagement with the gunwale to connect the device with the boat.

3. A device of the character described including an open-ended stirrup socket, arms extending from the socket and terminating below the inner end thereof forsupporting the inner end or" the socket above the plane of the free ends of said arms, clamping arms projecting from the socket and terminating in a plane below the free extremities of said Iirst mentioned arms, and clamping means carried by one of said clamping arms and adjustable thereon to coeperate with the other for connecting the device with a boat.

1-. A device of the character described in? cluding a stirrup socket, supporting arms swinginglv connected thereto, and means for connecting the device with a boat.

5. A device of the character described including a stirrup socket, supporting arms swingingly connected thereto, means for locking the said arms in active position, and means for connecting the device to a boat.

6. A device of the character described in cluding a stirrup socket, supporting arms swingingly connected thereto, coacting means carried by said arms and the socket respectively for locking the arms in active position, and means for connecting the de-' vice with a boat.

7. A device of the character described including a stirrup socket, lugs carried thereby and provided with slots, arms swingingly connected with the socket and provided with ribs engageable in said slots for locking the arms in active position, and means for connecting the device with a boat.

8. A device of the character described including a stirrup socket, pairs of lugs carried thereby, supporting arms for the socket, pivot pins swingingly connecting the arms with said pairs of lugs, certain of said lugs being provided with slots, ribs carried by the arms, the arms being movable longitudinally of said pivot pins to engage the lugs thereof within said slots for locking the arms in active position, and means for connecting the device witha boat.

9. A device of the character described, including a stirrup socket, supporting arms swinginglyconnected thereto, means for connecting the device with a boat, and means for limiting the arms in their swinging movement to active position.

10. A device of the character described in cluding a stirrup socket provided with lugs, supporting arms swingingly connected to the socket and provided with lugs engage able with the first lugs for limiting the arms in their swinging movement to active position, and means for connecting the device with a boat.

In testimony whereof I affix my signature.
