IMPROVEMENT |`N WATER-WHEELS.

The Schedule referred tovinxhese Letters Patent ana making part of the same.

l'o all whom 'itgnzay concern Be it known that I, WILLIAM H. ELMER, oferf 1lin, in'the county of Green Lake 'and in the State of Wisconsin, haveinvented certain new andnseful Improvements in Water-\\'heels; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing and to the letters ot'ret'erence marked thereon making a part of: this specification.'

The nature of my invention consists in the eonstruction and arrangement of thecasing of a waterwheel, and in the construct-ion 'and manner of operating the gates, as will be hereinafter fully set' forth.

In order to .enable others skilled in the arl; to which my invention appertains to make and use the same,I will now proceed to describe its construction and operation, referring to the annexed'drawing, in which- A Figure l is a pla-u viewy of mywheel, portions thereofbeing in section y Figure 2 is a side view of one oi' thegates; Aand Figure 3 isa ves'cal sect-ionthrough one ofthe chutes.

A represents the casing7 within which the waterwheel works.

This casing, with the chutes B B, is all cast toge-ther, making it very strong and durable.

The upper and lower parts of the chutes are be-ve'led,'as shown in g.3, so tha-t the water has no parallel surface to pass in going to the wheel, and no loss by friction. A o l At the end of each chutes'hinged a gate, C, which is sofconstruoted that when it is shut .it ils-perfectly tight, being held to its place by the pressure of the water. The' outer end ot each gate rests against the next chute instead of against the adjoiuinggate, as

isl now most4 generallyethe case, tlius forming a, solid bearing for the gate.

The case and gates are dared .up so that the)T will be perfectly tight. Y

Near the' outer end of each gate is a pin, b, pro.- jecting upward,- which pins are operated by means of inclined, cam-'shaped arms, D D, projecting from a ring or wheel, E, said wheel resting upon the upper surface of the easing around a collar on the same, and is turnedby means of'a pinion, dupon an upright shaft, G, engaging with a. rack, H, onv the wheel` E.

It will be observed that the cams D D open the gates and the water shuts them, so that in case an obstruct-ion gets into one it does rnot prevent tlrelrest from shutting.

Having thus fully described my invention,

lVhat I olaim as new, and desire to secure by Let- 1. lhe casing A and chutes B B, constructed as Y described and formed iu one, both the upper and lower parts of the chutes being beveled, as shown, substantially as. and for the purposes herein's'et` forth.

'2. I lhecombination of the easing A, chutes B B, gates' C C, pins b b, arms D D, wheel E, rack H, and pinion d, all constructed and arranged as described,

substantially as and for the .purposes herein -set forth. A l

In testimony that I claim the foregoing, I have hereunto set my lla-nd this 15th day of April,1870.

\VILLI AM H. ELMER.
