Letters Patent No. V109,286, dated November 15, 1870.

IMPRQVEMENT IN PADDLE-WHEELS.

The Schedule referred to in these Letters Patent and making part of the same.

My invention consists iu an improved mode of eonstruoting paddle-wheels, by which the whole of their working power is made available.

To make the invention better understoodl will proceed to describe it by reference to the accompanying Figure l is a section on the line A B a b of Figure 2, which vis a side elevation of apaddle-wheel constructed according to my improvements.

The paddle,'A A, properly so called, consists of a sheet or plate of metal or wood, jointed at c e to a shaft, M, the ends of which are iixed in a suitable manner to the frame-work of the wheel It.

Each paddle is provided, at`tl1e inner side of the wheel, with an extension piece, C, having at its extremity a buffer, D, and, at the outer side, each paddle is formed with a joint, b, united by a connectingrod, E, to another joint, h., placed on the extension piece C of the next paddle. v

All the paddles are thus united one to another, and

thelength of the rods is so regulated that one paddle is forced to incline, inl turning, on the shaft M.

This paddle acts on the two connecting-rods E, to which it is jointed at b and h in such' a manner as to draw into a radial position the paddle which precedes it and that which follows it. l

To insure greater rmnessto the paddle when it is drawnby the action of the lwater into this radial position, the buffer D, made of washers of India rubber or other elastic material, strikes against an abutment, G, iixed to the framework of the wheel by means of two crank-pins, and by this means the paddle becomes fixed.

The action of a wheel thus constructed and set in motion in the water is as follows: l

The paddle, entering the water in its radial position, will incline under the resistance ofthe water, andv will take an oblique direction, the two paddles next it being brought back to their radial position. In continuing its movement the paddle meets with less resistance, and recovers its radial position from the action of the movement of the preceding paddle, which becomes inclined as it passesl through the water, and the same action takes place for all the paddles.

rlhis arrangement, which causes the paddles toyie-ld to the resistance of the water, econoinizes the motive power, enabling it to give greater speed with the `'saine power and the same number of tn'rns,or of einploying less. power when it itis not required to increase vthe speedV of theressel. rlhe shockl is also less, and the quantity of water thrown up is diminished, thus giving amore useful ei'ect to the motive power.

I do not confine myself to the number of paddles or to their angle of inclination, as their number and angle of inclination may be varied, according to the lapplication or speed of the paddle-wheels.

Having now described m y said invention,

The oscillating paddle A, furnished with an extension piece, C, and an' elastic bufi'er, D, attached thereto, in combination with the connecting-rod E and the abutment G, arranged and'operating as herein described.

In testimony whereof, I, the said SAMUEL BATEMAN, have hereto set my hand and affixed my seal, this thirteenth day of August, one thousand eight hundred and sixty-nine.
