SPECIFICATION forming part of Letters Patent No. 252,432, dated January 1'7, 1882. Application filed June 1 1, 1881. (No model.) I i To all whom z'tmay concern:

Be it known that I, LEEDS A. COOK, a citizen of the United States, resident of Hanover, in the county of Jackson and State of Michigan, have invented a ncw and valuable Int provementinRowingGears; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation ofthe same, reference being bad to the annexed drawings, making a part of this specilication, and to the letters and figurcsot' reference marked thereon. t

Figure l of the drawings is a representation of a plan view of my devic Fig. 2 is a rear view, showing the car raised out of the water.

Fig. 3 is a perspective view; and Fig. 4 is a sectional view, showing the oar in the water. This invention relates to improvements in devices for propelling row-boats; and it consists in a construction whereby the rower can face the bow of the boat, and at the same time lift the oar easily from .the water attlie tinish, as hereinafter set forth.

Heretofore in the class of devices oi this kind where the rower faces the bow there has been no easy means for the equivalentfof t'eathering, so that the oar can be readily withdrawn for the recover without loss go'f speed by back-pressure on the blade. In stich old devices sufficient support has not been given to the bearing of the our at the gunwale, so as to relieve the rower of much of its weight. In the present device these objects are obtained. A broad fullbearing is atl'orded the oar during its sweep, and an easy withdrawal of the blade at the end ot-the' stroke.

In the annexed drawings, the letter a rep- Held by journ als f g in these bearin gs is a rockshaft, 0, arranged lengthwise the boat, from which shaft, at its end e,.diverges outwardly and. forwardly the curved rest It, and inwardly and forwardly the curved brace 7c, the former longer thanthe latter. Secured near its ends to those of the rest and brace is an obliquelyarranged cross bar, l, which is fastened to rock-shaft e where it crosses the'latter, and is on the angle the car would have when at the beginning of the stroke, thereby forming an abutment. Attached firmly to the inner end, or, of this cross-bar l is a looped couplingstrap, a, between the open ends p of which is pivoted the inner end of the oarq. This latter extendsout over the brace,rock-shaft, and rest, having its bearing on the latter two throughout its entire sweep.

Secured loosely to the outer end, 0', of crossrearward, carries between its forks t the pivoted outer end, a, of the hand-lever v. This lever 12 is swiveled by bolt to to the oar q, and extends inboard, so that the hand-gra p x is at the proper position For the rower.

From this description it will be readily seen that the oar moves with the hand-levegand not in opposite directions, like the blade and hand-grasp of an ordinary oar. This enables the rower to face the bow and see where he is going. The car has a good rest during the whole of the stroke, relieving the oarsman of the weight, and at the finish by pressing down on the hand-lever the rock-shaft turns, bringout even the slight back-pressure of feathering. There are to be two of these devices on other accompanying features, forms a jointed oar easily and quickly managed with slight fatigue.

-1 claimt The combination of oar q, hand-lever o, swiveled together, rock-shaft 0, rest It, and brace connected to the shaft and extending forwardly, connecting-rod s, and couplingstrap n, as set forth.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
