' OAR LOCK.

Application filed. August 5, 1925.

This invention relates to car looks and among the objects of the invention are the provision of a simple device of the character set forth which can be easily mounted and dismounted, but which when in position is effectively prevented from being accidently displaced.

In the drawing accompanying and forming part of the present specification I have represented in detail an advantageous form of embodiment of the invention which to enable thos skilled in the art to practice the same will be set forth fully in the following description. I am not restricted to this exact disclosure. I may depart therefrom in several particulars within the scope of the invention defined by the claims following such description.

Referring to the drawing:

Fig. 1 is an isometricperspective view of a boat equipped with two of the oar locks involving the invention.

Fig. 2 is an end elevation.

Fig. 3 is a side elevation showing one of the sections as fitted up to either mount or dismount an oar.

Like characters refer to like parts throughout the several views.

The device involves in its construction a mounting member, such as that denoted in a general way by 2. It consists of an elongated shank, as 3, having a U shaped head, as 4. The shank is adapted to be passed downwardly through an opening in the gunwale of the boat 5 until the base or central portion of the U shaped member a rests on the upper edge of the gunwale.

The oar holder, which is denoted in a general way by 6, is practically of circular formation, and comprises, as shown, semi-circular members, as 7 and 8, which are pivoted together at their butts, as at 9. The semi circular or base member 7, as shown, has integral with it the sleeve 10 whichreceives a pivot as 11 which turns on an axis horizontally disposed. The ends of the bolt or pivot 11 are seated in the arms of the U shaped member 4, one of the ends having a threaded connection with an arm, while the other extends outwardly beyond the arm and receives a nut 12, by removing which the bolt or pivot 11 can be taken from place. The mounting of the parts provides free action of the oars 13.

practically an enlargement of the stud. The

nut in said Fig. 3 is around both sections 15 and 16 of the stud or screw so as to clamp both sections of the screw or stud and thus the sections 7 and 8 together. By unscrewing the nut 17 the sections 7 and 8 will be relieved so that the section 8 can be swung open, as shown in said Fig. 3, to

either mount or dismount an oar. It will be assumed that an oar has been mounted, in which event the section 8 will be closed in abutment with the section 7, thus bringing the portions of the screw into engagement so that the nut 17 can be turned backwardly thus locking the sections 7 and 8 closed to prevent the accidental displacement of the ear.

The head 10 and the integral section 7 have through them a passage as 19 to receive oil to lubricate the pivot or stud 11. This efiective lubrication is an advantage.

VVhat- I claim is: r

1. An oar lock comprising a pivotally mounted annular oar receiving member comprising a pluralityot portions and pivotally mounted, the portions of the oar re ceiving member having a divided stud, the divisions of which are rigid with the respective sections of the oar lock, one division having a cylindrical portion overlapping the other division and a nut threaded on the stud, one of the sections of the stud having an enlargement.

2. An oar lockcomprising a pivotally mounted annular oar receiving member having a plurality of pivotally mounted portions which have a divided stud, the divisions of which are rigid with the sections of the oar lock, one divisionhaving a cylindrical portion overlapping the other division a nut threaded on the stud, one of the sections of the stud having an enlargement to prevent dismounting of the nut, and a mounting member to which the ear receiving member is pivotally connected.

In testimony whereof I aifix my signature.

SAMUEL MANCHESTER.
