The Schedule referred to in these Lettera Patent and making part of the sama.

To all whom it ma/y concern: l l

Be it known that we, D HOLDIMAN` and S. GOOD- wm, of Waterloo, in the county of Black Hawk, and State of Iowa, have invented a new and improved Water-Wheel; and we do hereby declare that the following is a full, clear, and exact description thereof, which will enablethose skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this speciication.

This invention relates to improvements in waterwheels; and g It consists in the construction of the wheel, and in the arrangement of. devices for operating thegates.

Figure 1 represents a plan view of our improved wheel, with a part broken away; and

` Figure 2 represents a sectional elevation, the lines x x, of g. 1, showing the planes of section.

. Similar letters of reference indicate corresponding` parts. A represents the upper portion of the curb, and

' B, the lower portion, from which the discharge-tube C projects in a downward direction, and 'is contracted at the end, which is designed to stand below the level of the water, whereby an effect of suction may be produced on the wheel. n The parts A and B of the curb are oevelled outwardly, to facilitate the entrance of the water to the gates, or chutes d, .which are pivoted near ,their inner ends, at e, and lap each other about half their length.

They are provided on their upper edges with the square projections f, which rise up through the curved slots y in the part A of the curb, and are provided with the sliding plates h, for covering the said slots, and are finally connected to the outer ends of the vibrating levers i, the inner ends of which rest in notches in the 'lower face of the loose ring D, arranged on the hub of the part A of the curb.

K represents vibrating arms, connecten to the arms f i, near their Outer ends, and to studs Lin the top of thepart A of the curb, which are designed to serve as fulcra for the arms i, on which they may oscillate in the act of moving the studs j' in the slots g.

The arms 'i are-placed in nearly a radial position with reference to the'ringl), and as it is evident that the ring D would not operate to throw the arms outward while in this position, it is necessary to provide an Os- .cillating fulcrum, to insure an outward movement of the arm, corresponding to the rotary motion of the ring.

yBy arranging the arms 'i radially, they are not crowded together at their fpoints of connection with the ring D,

as wouldbe-.the-,caseif they were arranged tangentially with reference /Nthe ring.` By the provision of the oscillating fulctuhrhaslight rotarymotion of the ling D communicates a direct ciitward or inward motion to thegates.v

m represents a forked arm, which is rigidly secured to the loose ring D, and is provided on its outer end with a segmental rack, fn, which is actuated by a pinion, o, on a vertical shaftA connecting with any suitable mechanism for operating it.

When it is turned in one direction, it will open the gates, or chutes, andin the other, will close them,

. through themedium of the mechanism, as above described.

The parts A and B of the case are connected together by the oval posts p, so formed as to present the least amount of resistance to the entrance of the water to the chutes, and provided with screw-bolts and nuts, whereby the said parts are fastened to them.

The wheel consists ofa disk, r, of suitable metal, having a' horizontal surface, s, extending from the edge inward a short distance, from thence inclining downward, at an obtuse angle, t, to the point u, and from thence extending, in a vertical line, c, tothe horizontal disk tu, which connects with the hub.

The buckets may be constructed of sheet-metal, and secured by their ends to the outerportion of the plate by bolting them thereto, or they may be soldered to it, or, if preferred, they may be cast together with vthe said plate.

' The discharge-passages, between the buckets, at'` operating-ring, and therefore were crowded at their point of connection with the ring. This, however. we do not claim.

We claim as new, and desire to secure by"Letters Patent t l 1. The arragement of the ring D, arms fi, Oscillating armsk, slidingplates h, 'studs l, curved slots g, square projections f, and gates d, operatingas described, for the purpose specied.

2. The wheel, constructed as described, ot' the outer horizontal surfaces, the angular portion t, vertical portion lv, and the horizontal disk w, connected with the hub, the buckets being securedin place at ,the points s, t, u, and c, as herein described, for the purpose specified.
