Description

HENRY W. CONNOR, OF TROY,'NEW YORK.

Letters .Patent No. 88,013, dated March 23, 1869.

nvrPRovnMENT IN ons.

To all lwho/m it may concern:

Be it known that I, HENRY W. CONNOR, of the city of Troy, county of Rensselaer, and State of New York,

. be propelled in the same direction faced by the oars` man.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

I construct the oar A in the usual and ordinary shape, except that I make the lower part of the oarblade wider than the upper part, so that the pressure will be greater below than above the oar.

About six inches of the loom, or upper end of the oar, I insert in a socket, B, made of metal, or other suitable material, so that the oar will freely turn in the socket, and be readily taken therefrom.

This socket B is attached to an upright, C, of sucient size to bear the strain at a point high enough to allow the oar-blade to work' in the water without striking the side of the boat, and is so attached by means of a joint or hinge, to allow a free movement of the oar in all directions.

Y The upright O is lirmly secured to the boat inthe centre; between the sides, and is the fulcrum of the oar..- y

As a means for working the oar, I make a band, H, of metal, or other proper mateu'al, of suthcient width and thickness to bear the strain upon it and make it to fit the oar, and at the same time to be movable upon it, and to be secured to the oar by means of a screw.

On the top of this band H, I put a -small hinge, F, which is on a direct line with the upper-'edge of the oar-blade, and on the bottom of this band I put a I broad pin, I, with a slot, or groove cut therein, which is on a direct line with the lower edge of the oar-blade. To this band H, I attach the jointed arm E, which is made of the length required by the oarsman.

This arm is made of metal, or other material, and is made with a handle, P, at one end, and with two prongs, or small arms, K and L, from the joint outward to the other end.

One of the small arms K is attached bya pin to the top of the band at F, which forms a hinge;

The other small arm, or prong L ofthe arm, Works easily in the slot, or groove of the pin I.

From or near the top of the upright C to the oar, near the band H, I attach a rubber, or other spring, D, which is to aid the oarsman in raising the oar from the water, and also to hold the oar into the socket B. This spring is attached to the oar, not on the top of the oar, but about one-third of the distance over toward the handle, and between F and I, so as to aid the oarsman in feat-hering the oar.

The operation is as follows:

When the oarsman, taking hold of the arm E by the handle P, pushes the oar out of the water, the arm, by the small arm K, being attached to the band H by the hinge F, which is on a line with the upper edge of the oar-blade, the oar, working in the socket B, is neces- Asarily rolled over backward, or feathered, until the stop O strikes the pin I, and thus remains so long as this force continues, the spring D aiding the operation. When the oar is put into the water, and the oarsman pulls upon it by the arm E, the oar is rolled back again until the stop G strikes the pin I, when the face of the oar-blade is necessarily in the propr` position in the water. The arm E being hinged or jointed, allows the oar to sweep around without inconvenience to the oarsman.

By this operation, the boat is propelled in the direction faced by the oarsman.

What Iclaim as my invention, and desire to secure by Letters Patent, 'is- The arm E, combined with the hinge F and the pin I, substantially as and for the purposes herein set forth.

HENRY W. CONNOR.
