HENRY REYNOLDS, OF ALBANY, NEW YORK.

IMPROVEMENT IN PADDLE-WHEELS.

Specication forming part of Letters Patent No. 154,908, dated September 8, 1874 application led January 10, 1874.

To all whom it may concern Be it known that I, HENRY REYNOLDS, of the city and county of Albany, and State of New York, have invented a new and useful Improvement in Paddle-Wheels, of which the following is a specification:

Figure I is a top view of my improved pad` (lle-wheel, and Fig. 2 is an end view of the same. v i

The invention will rst be fully described, and then pointed out in the claim.

A represents the shaft, which is connected with the vessel, and to which power is applied in the ordinary manner. To tlie shaft A are attached two sets of radial arms, B,

' each outer arm of each set being parallel with the correspondinginner arm of the other set. O are the buckets, which are attached to the arms ot' the two sets. The buckets of the two sets of arms incline toward each other and to the rearward, as shown in Fig. 1, and are intermediate with respect to each other, so that the wash from each preceding bucket may be met by the succeeding bucket, and thus increase thel leverage, thus making the wheel more effective. A

The distance apart of the sets of buckets prevents. any waste of,n power or churning from the waste-water.

The lines of the inner ends ofthe buckets of the two sets are at such a distance apart that v the driving-power may be readily connected with the center of the shaft A when the wheel is placed at the stern of the boat.

By this construction the same amount of bucket-space will be submerged all the time, so that the action of the Wheel will be uniform.

The end of the arms B is shouldered to the same width as the buckets, and at such an angle, dependent on the pitch of the buckets and the distance apart of the arms, as may be deemed necessary.

The arrangement of the 'paddles in my inc the swell is graduated and continuous, being4 produced by the angle and alternation of the buckets. With my wheel no greater swell is raised by the operation of the buckets than would be by a screw completely immersed,

while the cost of operating it is as economical.

as by the screw, for the reason that its hold upon the water is at all times the same.

I secureva greater power than is usual, because the bucketsV always work in the cross- Wash of each other, affording a better leverage than would be obtained in dead water.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The combination of two wheels, made fast at a short distance apart on the same rotary shaft A, having their respective sets of buckets arranged obliquely thereacross, and having the opposite points of corresponding buckets of the two wheels arranged above oribelow and at an obtuse angle to each other, as

and for the purpose described. v

HENRY REYNOLDS.
