ROWING-GEAR FOR BOATS.

SPECIFICATION forming part of Letters Patent No. 319,935, dated June 9, 1885.

pplication filed August 30, 1884. (No model.)

To all whom it may concern,.-

Be it known that I, DANIEL S'rocxrNG, a citizen of the United States, residing at Fort Atkinson, in the county of Jefferson and State in the art to which it appertains to make and use the same, reference being had to the ac-l companying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

My invention relates to rowing-gear for boats; and it consists in the mechanism hereinafter described, whereby I secure great strength, force, convenience, utilization of power, and ease of manipulation in bow-facing oars.

In the drawings, Figure l is a top view of my device, showing its position in rowing at the moment when the blade of the oar at the beginning of the stroke strikes the water, and by dotted lines indicating its position at the moment the blade is lifted from the water at the close of the stroke. Fig. 2 is a rear view of my device attached to the gunwale of the boat on the line of motion of the oar and handlever. Fig. 3 is a detail showing rocking bar and method of attachment to the gunwalc of the boat.

The same letters refer to like parts in all the views.

In the drawings, A is the gunwale of the boat. B is a rocking bar. C is a hand-lever, and D is the oar.

The rocking barB is a plate having its ends p upturned, forming lugs c and I), and through which it is pivoted to plate c, having corresponding lugs, d and e, at its respective ends, whereby said rocking bar has a rocking or revolving motion at right angles to its length, said plate c being affixed to the top of the gunwale A, preferably by bolts affixed in the gunwale, and having upwardly-extending ends provided with screw-threads and hand-nuts f f, said plate c being also provided with recesses, one near each end on either side extending inwardly from the edge of the plate, adapted to receive the retaining-bolts extending upwardly from tbc gunwalc, said recesses being so located on opposite edges of the plate that the resistance offered by the stroke of the oar in rowing crowds the plate at said recesses against and upon said bolts, said plate being also held firmly in position upon the gunwale by the thumb-screws f f on said retaining-bolts, and j being adapted by means of said recesses to be readily removed from and replaced on the gun- VWale when desired, the releasing or attaching ing bar at t' by a bolt passing through it and i through the lug g, and the oarD is pivoted on said rocking bar at j by a bolt passing through it and through the-lug h.

The tension-arm k is hinged at one extremity to the short arm of the hand-lever C, which extends outwardly from the fulcrum t', and at the other extremity to the short arm of the oar D, which extends inwardly from the fulcrum j. It is obvious that power exerted on the long innerarrn of hand-lever G in the direction of and forcing this arm toward the stern of the boat would move the blade of the oar in the same direction, thereby propelling the boat forward, whereby the rower is required to face the bow of the boat in Vpropelling the boat ahead by pulling on this oar in the ordinary manner of operating oars.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In rowing-gear for boats, the plate c, provided with diagonally-opposite recesses on its longitudinal edges adapted to receive and bear against the retaining-bolts fixed in and extending upwardly from the gunwale of the boat, and end lugs d and e, in combination with the rocking plate B, provided with diagonallyopposite apertures g and h, for attachment of the oar and lever, and with the end lugs a and b, by and through which lugs said rocking plate is pivoted to the plate c, substantiall as and for the purpose set forth. l

2. In rowing-gear for boats, the plate c, prooted on the rocking plate, the one at hand the vided with diagonally-opposite recesses on its other at g, and the tension-arm 7c, hinged at longitudinal edges adapted to receive and bear one extremity to the inner end of the short I5 against the retaining-bolts fixed in and extendarm of the oar, and at the other extremity to 5 ing upwardly from the gunwale of the boat, the outer end of the short arm of the lever C, end lugs d and e, and rocking plate B, prol substantially as and for the purpose set forth. vided with diagonally-opposite apertures g and In testimony whereof I afx my signature in l1, for attachment of the oar andlever, and with presence of two witnesses.
