' SAMUEL SEARLE HAZELAND, OF PARISH OF ST. SAMPSONS, COUNTY OF CORNWALL, ENGLAND.

OAR AND OAR-LOCK.

SPECIFICATION forming. part of Letters Patent No. 281,873 dated July 24, 1883.

Application filed October 527, 1882.

To aZZ whom/it may concern Be it known that I, SAMUEL SEARLE HAZE- LAND, of the parish of St. Sampsons, in the county of Cornwall, England, experimental machinist, have invented a new and useful Improvement in Oars and Bowlocks, of which the following is a specification, reference being had to the accompanying drawings.

This invention consists in an improvement in oars and rowlocks, hereinafter described and claimed, whereby great command of the oar is afforded to the rower.

In the accompanying drawings I have shown my improved car and the means for mounting it in the gunwale of a boat.

Figures 1 and 2 show, respectively, the in ner and outer ends of the complete oar mounted in the gunwale in the rowing position. Fig. 1 is a section taken on the line 1 2 of Fig. 1. Figs. 2 and 2 are sectional views, showing the position of the blade when pulling and feathering. Figs. 3 and 4 are sectional views of the improved rowlock, showing the mode in which it is fitted to the oar. Figs. 5 and 6 are plan and edge views, respectively, of the fixed blade employed when the oar mounted in the improved rowlock is to be feathered by hand instead of automatically.

In these figures, A is the shaft; B, the selffeathering blade, secured by slotted collars b b and pins 1) b to the outer end of the shaft in such a manner as to be capable of moving through an arc of ninety degrees, as shown clearly in Figs. 2 and 2", the former representing the vertical position of the blade in the water when pulling; and the latter the horizontal or feathering position assumed by the blade after leaving the water.

0 is the crutch rowlock, swiveling on the pin 0 in a hole in the gunwale D of the boat. The arms of the crutch rowlock O are formed with horizontal lumps or sockets G", which are bored to form long bearings for the trunnions e of a ring, E, which encircles the shaft A at the point where it is to be supported by the (No model.)

rowlock. The ring E is free to oscillate upon its trunnions c c, and is held in position on the shaft of the oar by means of two collars or flanged rings, G G, which lie one 011 either side of the ring E, and are secured to the oar by screws, as shown in Fig. 4. The trunnions e e are formed, as shown best at Fig. 3, with smooth cylindrical stems, threaded ends, and screw-heads. The threaded ends are set up after the trunnions have been screwed into the band or ring E. The rings G G are made sufficiently large to be put on over the handle of the oar, and a filling of leather or other material, F, may be inserted, if necessary, between the rings G G and the oar, so as to allow of their fitting accurately. There is an annular space between the collars G G, and a stoppiece, H, Fig. 3, is screwed to the oar between the said collars, so that when the screw stoppin K is inserted in a hole formed for this purpose in the top of the ring E the degree of axial motion which can be given to the shaft A is restricted, and the rower can at once set the shaft in such a position as will bring the self-feathering blade 13 into position for pulling or backing water. When oars having blades of the ordinary form are used, the screw-pin K may be removed and the oar may be feathered by hand. I11 this case the self -feathering blade may be replaced by a blade of the construction shown in Figs. 5 and 6. This blade B consists of a central portion, B, secured to the shaft of the oar A by a square pin and socket -joint, and two side pieces, B B riveted to the central portion, B, and extending beyond it, 011 either side thereof, the projecting ends being secured to the shaft A by a collar or its equivalent, A.

From the foregoing description it will be seen that an oar mounted in a rowloek as shown is capable of a double swiveling motion, and also of an axial motion, which movements afford the rower the greatest command over the oar, and by means of the removable screw stop-pin K he is able to use either an car with a selffeathering blade or an oar having a motion of the shaft within the said ring, all fixed blade of the ordinary form, or of the substantially as herein described.

novel construction shown in Fi 's. 5 and 6.
