OAR-LOCK.
SPECIFICATION forming part of Letters Patent No. 262,108, dated August 1, 1882.
Application filed May 3, 1882.
To all whom it may concern:
Be it known that I, JOHN W. PARKER, of Clinton, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Rowlochs; and I do hereby declare that the following is a full, clear, and exact description thereof', reference being had to the accompanying drawings, and to the letters of reference marked IO thereon, which form part ot` this specifica-tion,
in which- Figure 1 is a perspective view ot' the improved rowlock secured to the gunwale ot' a boat. Fig. 2 is a vertical sectional view ofthe I5 rowlock. Fig. 3 shows my invention applied to an Outrigger; and Fig. 4 is a modification, showing the rowlock applied to a supplemental piece on the gun wale.
This invention relates to rowlocks, and the nature of my invention consists in the combination ot' a hook or horn adapted to receive an oar, which is swiveled to a vertical post, a lug cast on the lower part of' said hook or horn, adapted to bear upon the plateor base ofthe rowlock and to relieve the post from undue strain while pulling an oar, anda conical Wear-l ing-seat for the tube ofthe swivel-hook, as will be hereinafter explained in connection with other features ot' my invention.
'.lhe letter A designates the gunwale of a boat, and B is a base-plate,which is constructed with a vertical post, C, and adapted to be rigidly secured upon the gunwale B. At the base otl the post C is a conical seat, D, upon which is supported the tubular portion E of a hook or horn or stirrup, F. The lower end of the tube E is eountersunk, as indicated at a, and adapted to swivel 011 the conical seat D. The upper end of the post C is perforated horithe stirrup the lug J will bear on the baseplate B with more or less pressure, and thus relieve the post C from strain and wear.
zontally, and receives through it a spring- (No model.)
It is obvious that the post may be formed on an Outrigger, and thatthe horn orstirrup may have its ends connected, so that a ring will be formed which will prevent the possibility ot' the oar jumping out ot' its place either when pulling or backing water.
The dotted lines on Fig. 3 indicate that a 6o ring may be used in lieu of a stirrup or horns.
The base-plate B is cast with studs on its bottom side, which are screw-threaded, and which pass through the gunwale of the boat and receive nuts on their lower ends that contine the base-plate and its post to the gunwalc B in a rigid manner. When the baseplate is secured to an Outrigger the screwthreaded studs will pass through and be rigidly secured to the table or junctions of the 7o arms ot' the Outrigger by the nuts above described. In some cases the base-plate may be riveted to the outer end ofthe Outrigger.
The base-plate may be let into the gunwale ilush with its top side, or it may be let into a gunwale-cleat or supplemental piece secured upon the gunwale.
The advantage of casting the base-plate and its lugs entire is that I obviate the necessity ot' drilling the base-plate and countersink- Sc ing to receive bolts, and I have a perfectly- Hush surface, with the i'astenings hidden from VlCW.
Having described my invention, I claiml. The combination of the base-plate, the post formed thereon', the hook or stirrup swiveled to the post, and the lug J, formed on the hook or stirrup, substantially in the manner and for the purposes described.
2. The combination of the base-plate, the 9o post formed thereon, the cone seat at the base of the post, the tube E, having a countersunlr lower end resting on the cone seat, and the hook or stirrup formed on one side of the said tube, substantially as described.
3. As anew article of manufacture, the bascplate B, the post C, and the lugs, all cast entire, for the purpose described.
In testimony that I claim the'foregoing as my own I afx my signature in presence of two roo witnesses.
JOHN W. PARKER.
