IMPROVEMENT IN WATER-WHEELS.

' 'Jl'he Schedule referred to in these Letters Patent and making part of the same.

To all whom 'it may concern.;

Beit known that I, SAMUEL MARTIN, of the city 'and county of York, and State of Pennsylvania, have invented a newand improved Water-Wheel; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawings'rnaking apart of this specification, in which- Figure lis a vertical central section througln the wheel, and

Figure 2 is a plan view Vof the curb, gates, and curved plates. v

This invention consists of certainimprovements .in turbine water-wheels, tending to increase their efficiency, as will hereinafter more f'ully appear.

In the drawingsi The wheel'is shown to consist of au upper disk, a, a lower disk, a', the lower being of somewhat greater diameter than` the upper, an intermediate parallel i ring, a", of the same diameteras the lower disk, the

upper and lower. disks being connected by a web, b. Projecting radially from the web b are vertical buckets bI the upper ends of which are placed beneath the disk a, 4while their lower ends are even with the under side of the ring c, which ring serres to support their lower parts between .itself and the web b.

The ring rests on curved buckets c, which 'themselves rest on the lower disk.

The curved buckets extend inward to the inner side of' the ring a", and outward nearly to its outer side.

'lbewater acts directly ou the 4buckets b', then falls upon the lower disk, and is, by't-lic centrifugal action ot' the wheel, swept against the inner sides of the. buckets c,'and out'of the', wheel between the ends of said buckets. lt thus'imparts a. reactionary force 'to i thecurved bucket-sl in addition lto its direct action upon the buckets b'. y y

To eachcurved buckets there is secured, by a set- -screw passing through' a slot lin the bucket, a'plate, c',

of the same shape andsze,'whose couvexity ts accurately the concavty of the bucket, and which may be 4slid outward, according to the length of the slot iu -the bucket, and thus diminish the size of the open# ings between the buckets, so is to prevent waste of' water.

In iig. 2 are seen the gates d, each by itself, and attached to a radial arm, d', projecting from a central hub, di.

The gates are arranged in pairs, the two of cach pairbeing exact-ly opposite each other, at dili'ereut sides of the curb, and all the gates moving at the same time.

This'arrangement places thegates in equilibrium as to the pressure ot the water, rendering it 'easy to open enclose them.

The end of each gate that enters the opening in the curb is provided with a curved vertical plate, e, set at an angle across such end and extending inward far enough to conduct the water past the Wal] of the curb.

Such plates form, with the 'plates e of the curb, gnideways that conduct the water 4to the wheel tangentially.

Having thus described my invention,

What I claim vas new, and desire to secure by Let ters Patent, is, 1. The combination of the vertical buckets b' with the curved buckets c,',inthe manner described and for the purpose of enabling the water both .to act directl y and to react upon the wheel.

. 2. In combination with the curved buckets c, the sliding adjustable plates c', in the manner and for the purpose described.

' 3. rlhe 'detached gates d when so combined with the revolving frame il d as to be all in equilibrio, in the manner and for the'purpose set forth.

,4. The gates' d combined with .the curved plates e, for the purpose of forming a perfect guideway, subst-antially as specified.

To the above specification ot my invention I have signed myA hand this 30th day of November, 1869.

S. MARTIN.
