UNITED sra'rss PAMPHILE GRAVEL, OF PORT ALFRED, QUEBEC, CANADA.

OAR.

Application filed January 27, 1922.

T 0 aZZ 711700771 it may concern Be it known that I, PAMPHILE GRAVEL, a subject of the King of Great Britain, residing at Port Alfred, Province of Quebec, Canada, have invented certain new and useful Improvements in Oars; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in propulsion devices for small boats, having for an object to provide a novel type of oars, such as is used for propelling small boats or the like over a body of water and being of such arrangement as will permit a rower or persons-using the same to face the direction in which the boat being so propelled, is travelling.

It is also an object of the invention to provide an improved oar or oar mechanism employing means for connecting the active elements thereof in a manner such as will permit of transmission of motion from one to the other with such a minimum amount of effort upon part of a user and also, will increase the range of the oar proper, so that greater speed and propulsion may be secured with but minimum efforts.

Other objects will be in part obvious and in part pointed out hereinafter.

In order that the invention and its mode of operation may be readily understood by persons skilled in the art, I have, in the accompanying illustrative drawings and in the detailed following description based thereon, set out one possible embodiment of the Serial No. 532,347.

invention may be stated to comprise oar sec tions, 1 and 2, the section 1 constituting the oar proper, that is, being provided upon its outer end with the usual paddle 3, while the section 2 constitutes the handle portion of the same, having its inner end reduced, as is usual, at l. I

To support the sections 1 and 2, I provide apertured bracket plates 5, arranging oppositely disposed bearing elements 6 thereon between which the right angularly disposed bearing ears 7 of a connecting and supporting bar 8 are pivotally received. This con necting bar 8, as will be noted, serves as an effectual means for pivotally supporting the oar sections 1 and 2 and permitting of their oscillatory motion with respect to the gunwales of the boat to which the oppositely disposed bracket plates 5 are connected as by screws or similar fastening devices.

Bifurcated bearing brackets 9 are formed upon the upper side at each end of the connecting bar 8, and one of these brackets 9 serves as means for pivotally connecting the angular reduced extension 10 of the oar section 2, while the other thereof serves to pivotally support similar extension 11 arranged or secured to the inner end portion of the oar section 1. Thus, it will be under stood that the oar sections 1 and 2 are pivoted for movement in substantially horizontal planes, to the opposite end portions of the bar 8, namely in the brackets 9 thereon. In order that vertical pivotal movement of said sections 1 and 2 may be had, that is, oscillatory movement of the same, said arm or bar 8, as hereinbefore described, has its bearing elements 7 pivotally received between the bearing elements 6 arranged upon the bracket plates 5. Hence, the usual motion employed in rowing a boat will be permitted of.

In order that the oar sections 1 and 2 may be interconnected and motion transmitted from the section 2 to the section 1, so that a boat equipped therewith will be propelled over the surface of a bodyof water in the direction being faced by an operator, bracket arms 12 are fixedly secured to said sections 1 and 2 as indicated at 13, and in turn, are pivotally connected to the opposite ends of a connecting bar 14, as at 15. In

this connection, it should be noted that the arrangement of the bracket arms 12 with respect to their particular sections 1 and 2 occurs at points slightly beyond the pivotal connection of said sections with the bar 8 and in consequence, transmission of power from the section 2 to the section 1 will be permitted. Furthermore, due to the interconnection oi the oar sections 1 and 2, section 1 may be coiled to be rocked in a direc tion to effect propulsion of a boat equipped therewith in that direction being faced by the operaton-hence, permitting such operator or user to more accurately control the course being traversed by the boat.

Manifestly, the construction shown is capable of considerable modification, and such modification as are within the scope of my claim, I consider within the spirit of my invention.

Having thus fully described the invention, what I claim as new and desire to protect by Letters Patent is An oar and supporting means therefor comprising a pair of spaced upright bifurcated members, horizontally bifurcated members having ears pivoted in said upright members, end pieces pivoted in said horizontally bifurcated members, oar sections having their inner ends received in said end pieces, and a connecting bar'pivoted to each of said sections.v

In witness whereof I have hereunto set my hand.

PAMTPHILE GRAVEL.
