IMPROVEMENT IN FEATHERING- PADDLE-WHEELS.

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

To all whom it may concer-n: l

Beit known that I, PRIMUS EMERSON, of Garondelet, in the county of St. Louis, and State of Missouri, have made certain new and useful Improvements in Feathering Paddle-Wheels; and I do -hereby declare the following to be a full and true description thereof, ying drawings, and to the letters of reference marked thereon.

This invention. relates to wheels, with paddles arranged movably in such wise that said paddles shall remain, during their motion, in a vertical, or very nearly vertical position, to prevent the same from lifting up bodies of water or from striking the water 4without acting fully and fairly to propel or otherwise give a useful effect.

The nature of this invention is, first, in the manner of feather-ing the paddles and of vsupporting theA same, to allow for the movement required for feathering, and

' secondly, in the manner of relieving the eccentric ring,

which herein acts to cause the feathering of the paddles, of friction to a great extent.

To enable those herein skilled to make and use my said improved paddle-wheel, I will now more fully dcscribe the same, referring to the accompanying Figure 1 as a side view; to

Figure 2 as a plan; and to Figure 3 as a sectional view, showing the manner of supporting the paddles in the wheel-rim.

-I support` the wheel in the usual manner by its axle A, in proper bearings, a, upon the usual frame.

Connected firmly to the axle, by suitable spider castings or other means, I arrange the wheel-arms. B, which support the wheel-rims C, the parts being secured by bolts or rivets in any manner desirable, and being formed of iron or wood. v

In the rims C, (of which there maybe two or more,) I arrange the paddles D, made of iron or wood.

Saidpaddles are arranged between the sernicircular segments E, usually made of cast-iron, and the paddles are'secured, by proper bolts passing through the central diametrical flanges of the segments E.

'lhese segments form a narrow cylinder, which turns freely in the wheel-rim C, being guided laterally by flanges or side-plates c, which are secured to the wheel-rims.

To said segments, I connect the journals e, all of which are, at their outer ends, connected with the eccentric ring F.

This ring has a series of radial arms, f, connecting with the inner ring F.

The parts F, j, and F are thus joined to forma united body. i l

In order to support the body thus formed, and allow the same to rotate, I arrange, eccentrically, to the shaft A the centre bearing G, supported by proper bracebars, g, to the wheel-frame.

'Said bearing has the rollers leon its outer circumference, and, to properly support the journals of said rollers, said bearing will usually liavecircular flanges,

H, generally as indicated in fig. 1.'

The flanges H mayrevolve with the rollers h about the centre of the bearing-piece G, or the rollersh may simply rotate about their own journals, which will then be firmly secured to the hearing aforesaid.

In the revolution of the wheel thus formed the rims O, and the paddles therein, revolve aboutthe axis of the shaft C, and as the ring F revolves about lachieved whether the journals e are at the upper edges of the segments E or at the lower edges thereof.,

vDuring this feathering-movement of the paddles, the

segments E turn in their housings, in the wheel-rims C, but are always firmly guided and supported ou all points of the circumference, thus resisting eiectually strains and contusion, whether arising from the currents of water or from duit-wood, ice, or` other obstructions. V

By attaching the journals e at the upper edges of the segments E, it is apparent that the featheringmovement of the paddles is in the directionof the water-pressure, as produced by the current madeby the wheel, and the feathering-movement thus requires little power of machinery for its accomplishment; but by thearrangement of the roller centre at G H h, the

power required inactuating the eccentric ring F is reduced to a minimum, especially as nearly all'friction is located centrally. p

` The paddles D may extend beyond the wheel-rims C, outside thereof some distance, the support, as given by the devices here described, to said paddles being sufcient to allow for such extension with proper safety. The arrangement and construction of feathering paddle-wheel thus described, recommends itself by its simplicity of form, avoiding the use of projecting-cranks for feathering, and generally having its detail features well protected against breakage by the usual obstructions, such as snags, drift-wood, and ice, attendant upon ordinary navigati-on.

Having thus fully described myinventiom.

' What I claim, is-

1. The circular segments E, arranged to supportthe paddles D, and to allow the feathering thereof in' the wheel-rimsC, substantially as set forth,

2. The segments E, their journals e, andthe eccentric F f F, when combined with rollers h, substantially-as set forth'.
