SPECIFICATION forming part of Letters Patent No. 717,980, dated January 6, 1903.

Application filed March 27,1902- Serial No. 100,273. (No model.)

51 otZZ whom it HY/(147] concern.-

Be it known that I, LAFAYETTE W. FLINT, a citizen of the United States, residing at Auburn, in the county' of Cayuga and State of New York, have invented a new and useful Bow-Facing Oar, of which the following is a specification.

This device relates to that class of oar-operating devices wherein the operator sits in the boat facing in the direction in which the boat is moving; and it consists in certain novel features of construction, as hereinafter shown and described, and specifically pointed out in the claims.

In the drawings illustrative of the invention, Figure 1 is a plan view of the device complete. Fig. 2 is an enlarged sectional detail of the operative parts. Fig. 3 is a seetional detail view of one of the joints of one of the oar members. Fig. 4 is a sectional detail view of Fig. 3. Fig. 5 is a section on the line m 00 of Fig. 2. Fig. 6 is a perspective view of one of the pivot-bolts detached.

The device is designed'to be attached to the gunw'ale of a boat forward of the seat instead of astern, as with the ordinary rowlocks, and will be disposed to oscillate verticallyto provide for the dip of the oar; but neither the boat nor the means of pivoting are shown, as the construction is so well known and forms no part of the present invention.

The device consists in two plates 10 11, spaced apart and united at the side by lugs 12 13 and connected by bolts 15. Secured in these lugs are the pivot-studs 16 17, by which the device is pivotally supported upon the gunwale and adapted to rock thereon when the oars are dipped into and removed from the water in the act of rowing. The blade end of the car is represented at 18 and the handle end at 19, each connected, as by bolts or other fastening means 20, at their inner ends, respectively, to arms 21 22. The arms 21 22 extend into the space between the plates 10 and 11 and are pivotally secured by bolts 23 24, passing through both the arms and plates, these bolts being disposed at right angles to the pivot- studs 16 and 17. The ends of the arms21 22 are each turned in reverse angles between the plates 10 and 1 1 and united at their ends by straps 25 26, one on each side of the arms, by pivotbolts 27 28, as shown. The bolts 27 28 are formed as shown in Fig.6, which represents one of them removed, with a comparatively largecenter and with smaller end portions, the endlportions being threadedand adapted to support nuts 29 outside the straps. The enlarged central portion of these bolts engage the arms 21 22, while the smaller ends engage the straps, as shown in Fig. 5.

Surrounding the larger portion of the bolts 27 28 within the arms 21 22 are bushings 30 in the form of small split cylinders, and each arm is provided with a set-screw 31, by which the bushings are maintained in place, as shown in Figs. land 5. The bushings will generally be of brass or other comparatively soft material, while the bolts 27 28 will preferably be of hardened steel. By this means the bushings serve as wearing-surfaces to receive all the wear and when worn out can be readily and quickly renewed, thus preventing wear upon the hardened parts and providing for keeping the joints always tight and free from rattling. The bushings are inexpensive,costing but a trifle, so that the renewal of the joint can be made at a trifling expense. When thus assembled and mounted upon the boat, motion imparted to the handle portion 19 will be correspondinglyimparted to the blade portion 18, but in reverse order, so that the rower will sit facing the direction in which the boatis moving while operating the oars.

The device is very strong and compact, and by the manner shown of forming the joints between the straps and arms 21 22 they may be easily kept tight and all lost motion and rattling obviated. The straps 25 26 by embracing both sides of the arms 21 22 greatly strengthen and support them and insure a correspondiugly-increased steadiness of action.

Having thus described the invention,what is claimed as new is 1. In a device of the class described, the car members mounted pivotally between plates that are spaced apart and provided with oppositely-extending pivot-studs, said oar members having their inner ends extended between said plates, links engaging opposite sides of said extended ends of the car mem bers, split metallic bushings arranged in perforations in the extended ends of the oar members, bolts having enlarged central unthreaded cylindrical portions engaging said bushings and screw-threaded ends extending through perforations in the ends of the links, and nuts upon the said threaded ends of the bolts, substantially as set forth.

2. In adevice of the class described, the oar members mounted pivotally between plates that are spaced apart and provided with oppositely-extending pivot-studs, said oar members having their inner ends extended between said plates, links engaging opposite sides of the said extended ends of the oar members, bushings arranged in perforations in the extended ends of the oar members,
