sleeve-like member 10 are provided with flanges 13 which extend below thatmember and embrace the 'gunwale 12,thus to keep that member in a relatively fixed position parallel to the gunwale, and these flanges are preferably formed by cutting the belly of 7 that member first lengthwise from its ends to the width of the flanges to be formed, then upwardly, and finally straightening out the relatively vertical po sition. v V r r Adapted for a limited'reciprocal rotary movementwithin the member 10 is the tubulzni'member}lt the ends of which, however, project considerably beyond the ends of the sleevemember and 'those ends of the tubular that member and engaging man annular seg- & mental slot 17 1nthe tubular member 14.,

This oariand lever carry pivot pins 21 provided with heads; 22." Portions of these pins extend beneaththe oarand'the lever and 1 upper portions of the pins are embraced in enter sockets 23in the lower ears, while the diagonal notchslots 24 in the upper ears.

- In, setting up'the mechanism it will be observed that'if theoar andv lever are first placed" in an elevated position between: the

ears whilst the upper portions of those'pins are trayersingthe diagonal'notch slots24,

until the foar, or lever as the casemay be, :arrlves'home, when the lower port onsof those pins may drop into their sockets '23 1 and the oar,, "or lever, asthe'case may be,

comes torest on its respective gallery. :For locking the oar and lever in their fulcrumed osition between the ears there. are provided notched latches or keepers 25 on theupper ears. ",Theselat'ches arepivoted as at26, and

are adapted to be swung in or'out ofengage- Theoar 18 'sff'ulcru'med' between the forment with the pivotsQI. Obviouslythe oar and lever may be disconnected from the tubular member by a reversalof the foregoing procedure.

Pivotally connecting the inboard end of. the oar 18and the outboard end of the lever 19 is the link 28; Although thislink and its pivotal connections-canbe, of any suit'able form and produce the same ultimate result, it is found preferable to; provide that link in the form of a' rod provided with an eye .29 atone end and a hook 30 at the opposite end. The eye 29 is-linked with a hook 31 on the outboard end" of" the lever 19* and the book 30 is linked with. an eye 32 on the ing0 board end of the oar 18. The relative posi,

tion of these, hooks andey'es' is obviously immaterial, the foregoing-relationship being'j,I

ing, however, that that relationship is a pref erable one, theend of the bill 33 of theloopj forming the eye 29wis proportionatelyn'ar- 1 illustratedby way of an example. Assumrowed to a diameter approximately the in tervening space or gap between the end of the bill '34 and the hook-back 35 of the hook; 3 1,Jsee Figure 9; Thus by manipulating the '11n'k28 to a position where: the hook bill 34 meets the narrowed end of the .bill 33" on the eye, the hook and eye may be readily disengaged provided, of course, that the lever.

obviously oncethe mechanism is locked in operative position it becomes-impossible for those parts to become accidentally separated. 7
