Nirnn STATES \VASHINGTON BRYANT, OF FRANKLIN, ARKANSAS.

PADDLE-WHEEL.

SPECEFICATION forming part of Letters Patent No. 379,352, dated March 13, 1888. A

Application filed November 10, 1857.

To all whom it may concern:

Be it known that l, Wnsrnnoron BRYANT, of Franklin, in the county of Izard and State of Arkansas, have invented a new and Improved Paddle-W'heel, of which the following is a full, clear, and exact description.

My invention relates to an improvement; in paddle-wheels, and has for its object to provide a wheel wherein the pad dlcs will enterthe water with the least possible resistance and leave the waterin a similar manner, but in whiclnwhen the said paddles are in the water, they will present the greatest possible hearingsurf'ace thereto.

The invention consists in the construction and combination of the several parts of the wheel,as will be hereinafter fully set forth,and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 illustrates a central transverse see- Fig. 2 is a longitudinal sectional View, partially on line a: :0 of Fig. 1; and Fig. 3 is a perspective view, partly in section, of the shift ing ring and collar.

In carrying out the invention the axle A of the wheel is mounted in a suitable frame, A, if used as a stern wheel, and when employed as a side wheel in a proper outer frame and in the side of the vessel. In each support of the axle and at each side of the bearing of said axle in the frame or ships side horizontal slots at a are cut in align ment with one another,and a ring, B, is secured to the inner side of said frame, or the outer surface of the ships side, provided with outwardly-projecting threaded pins 1) b, adapted to enter and pass through the aforesaid aligning slots a and a, respectively.

Upon the outside of the outer frame or support, A, suitable nuts, 0, are provided the pins 1) b and screwed thereon in such manner as to admit of lateral play of said pins in their said slots. The pins, projecting through the side of the frame or support through which the axle extends and where power is applied to the axle, are secured by suitable nuts to a horizontal sliding plate, D, which plate is provided with an elongated slot, d, to receive the axle A, and

Serial No. 254,771. (No model.)

made to extend farther beyond said axle upon one side than upon the other. To this extended end d of the sliding plate D a vertical lever, E, is attached, i'ulcrumed upon a bar, F, secured to the ships side or to the inner surface of the inner support, A.

The rings B are secured to the frame A in such manner as to be eccentric with the axle, the greatest point of eccentricity being in front of the axle, or at a point aligning horizontally the position the paddles assume when passing downward to the water.

Instead of the slots a a being out in the ships hull when the wheel is in position at the side,

the said slots may be cut in a timber secured to the hull.

The axle A of the wheel, within the frame and near each end, is provided with integral hubs H, in which are secured a number of carryingarms, H, equal to the number of paddles to be placed in the wheel. The arms H, radiating from the hubs,are curved at apoint,preferably above their center, in the direction in which the wheel is intended to move when propelling the vessel forward, as shown in Fig. 1, each arm being provided with an eye in the end.

The ring B is provided with an inwardlyextending fiange,m,as shown in Fig. 3, adapted to receive a collar, M, having a recessed inner face and a series of equidistanced peripheral slots, 777,, equal in number to the number of arms H, and adapted to be positioned in substantial alignment with said arms. To the inner surface of the collar M, within the recess in", aseries of rods, N, are secured,which rods project up through the slots m, and, curving inward to the rear of the arms H, have their ends bent at right angles, also inward.

The paddles N, which may be made as broad as desired-say five or six feet are made with a front and rear concave surface, a n, and of greater thickness upon one longitudinal side, 00?, than the other, as illustrated in Fig. 1, the said thick edge being chamfered ofl' upon the rear side at the ends to permit perfect freedom of play when pivoted to the arm H.

Upon the rear of each paddle, centrally the same and near the ends, posts 0 are secured, having inwardly-extending opposing pins 0 and an aperture, P, near the end. To place will be made concentric with the axle.

the paddles in position, the arms H are brought down to a substantially vertical position and the paddle is placed transversely the frame, face out and heavy end up. The pins 0 are then made to enter the eyes in the arms H and secured in position by nuts or other suitable means. The angular ends of'the rods N are then passed through the apertures P of the posts and secured therein similar to the pins 0'.

The paddles may be more or less boxed along their thick side and partially at the ends, so that by manipulating the lever E the ring B The brackets will thereupon lift the water, and in a stern wheel throw the same over the deck, which in the event of firewill materially aid in extinguishing the same. i

It will be observed that the paddles enter the water in an almost vertical position and pass out therefrom in substantially the same position.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. The combination. with the axle A, carrying curved arms H, and paddles N, provided with a concaved front and rear surface and one weighted longitudinal edge pivoted to said arms, of eccentric rings B, collars M. sup ported by said rings, and curved bars N, radiating from said collar and pivoted to said paddles above said arms,substantially as shown and described, and for the purpose herein set forth.

2. The combination, with the axle A, carrying curved arms H, and paddles N, provided with a concaved front and rear surface and one weighted longitudinal edge pivoted to said arms, of the eccentric rings B, a collar, M, supported by each of said rings,provided with o a recessed inner face, 111?, a series of peripheral recesses, m, and a series of curved rods, N, attached to said collar, passing through said recesses,and pivoted to the paddles above the arms H,substantially as shown and described.

3. The combination, with the axle A, provided with integral hubs H, having attached thereto a series of curved carrying-arms, H, and paddles N, provided with concaved front and rear faces, a weighted longitudinal edge, and posts O,'attached to the rear face, provided with apin, O, and aperture 1?, of the eccentric rings B, a collar, M, supported by said rings, provided with a recessed inner face, on", a series of peripheral recesses, m, and a series of curved rods, N, attached tosaid collar, passing through said recesses, and pivoted to the paddles above the arms H, substantially as herein set forth.

4. The combination,with the frame A, provided with aligning recesses a a, the axle A, carrying curved arms H,and paddles N,piv oted to said arms, of the eccentric rings B, provided with aligning pins 1) b, a collar, M, supported by said rings, curved bars N, ra- 6 diating from said collars and pivoted to said paddles above saidarms,the slotted horizontal bar D, and lever E, all arranged to operate substantially as herein set fort-h.
