@with tatsatw-t @frn MICHAEL A. LANAGAN," 0F BROOKLYN, NEW YORK,4 ASSIGNOR TO .HIMSELF AND JOHN DAILEY, OF SAME PLACE. f
Letters Patent No. 72,865, dated December 31, 1867,
IMPROVEMENT moan-Leens.
TO ALL WHOM IT MAY CONCERN:
Be it known that I, MICHAEL A. LANAGAN, of Brooklyn, Kings county, New York, haveinvented a new;a'nd useful Improvement in Oar-Locks and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which-- Figure l is a side view of my improved oar-lock, part being-broken awag,T to show the construction.
Figure 2 is a detail sectional view of the same. i
Similar letters of reference indicate corresponding parte'.
My invention has for its object to furnish an improved oar-lock that will allow the oar to be moved freely in every'direction, from which it will be impossible for the oar to escape, should it be'dropped, in which it may be quickly placed, and from which itmay be quickly. removed; and iteonsistsiu making the part oflthe oarlock that receives the oar in two parts, hinged to each other, and in the combinationof the rolling oar-lock and pivoted eye-bolt with each other; the wholebeing constructed and arranged as hereinafter more fully described.
A is the oar-lock, which is made in two parts,V al and a2. The pieces a and a2 are hinged to' each other, so that the upper part or piece may be Y'turned back to introduce or remove-the oar. The other endslvot` the pieces a and az overlap each other, and are kept in place'bya pin, B, which is passed into a holc formed partly in' each of the overlapped ends of the said pieces, as shownin g. 1. The pin B is kept from being mislaid or lost, when removed from the oar-lock A, by being attached to the end of a short chain? the other. end of which ifs secured to the lower part of the oar-lockin such a position lthat itwill notinterfere with -the movements of said oar-lock. The low-er part of the oar-lock A has a tcnon, a3, formed upon it, the llower end of which is rounded oif, and which is pvoted between two projections, c',V formed upon the upper end of the bolt C, by-which the oar-lock A is pivoted and secured to the gunwale-'of the boat. Theupper ends ofthe projections c are rounded oil, and enter and work in recesses or cavities formed in the lower part oi' thepiece a of the oar-lock A, upon both sides of the tenen a3. This construction gives-a'rooking or rolling motion to the row-lock, which enables the blade of the oar to be raised out of or lowered into the water to anydesired extent. The bolt C-may be swivellcd or pivoted to the gunwale of the boat in any convenient orknownl manner. '.lhe device hereinafter described is a very convenient means for doing this. I'
l) is a plate, which is screwed fast lto the gunwale ofthe boat.V In the centre of the plate VD is formed a. hole, having a screw-thread cut in its surface. E is a nut, whichis'screwed into thevhole in the plate D, and which has a hole formed through its centre-for the reception of the bolt C. The lower part or end of the bolt C is cut down or made smaller, and has a screw-thread cnt upon it for the reception of the nut F, which prevents the bolt C from beingwithdrawn from the nut E, while, at the same time, the said bolt is free to turn in either direction. The nut F may be screwed up against the under side of the nut E, or into a countersink formed in the under side of said nut. By this construction, the oars are free to move back and forth, while, at the same time, the rolling or rocking of said oar-lock makes them free to be moved up or down.
It should be observed that the opening in the oar-lock A, that receives the oar, should be large enough for the oar to work easily, and, at the same time, so small that neither end of the oar can pass through it, thus preventing the oar from being lost, should the oarsman accidentally let go of it.
Having thus described my invention, what I claim as new, and' `desire to secure by Letters Patent, is
The combination of the hinged row-lock A and pivoting-bolt C with each other, substantially as herein shown and described, and for the purpose set forth.
The above specification of my invention signed by me, this 9th day of September, 1867.
MICHAEL A. LANAGAN.
