Letters .Patent No.,98,561, dated January 4, 1870.

IMPROVEMENT :IINV WATER-WHEELS,

The Schedule referred to n these Letters Patent and making part of the same To all whom it `may concern:

gate; second, in the construction of the buckets of the water-wheel; and third, in the construction and arrangement of the devices for hoisting all the gates at one operation.

In order to enable others skilled in-the art to which my invention appertains, to make and use the same,'I will now proceed to describe its construction and op era-tion, referring to the annexed drawings, in which--v Figure l is a perspective view, and

Figure 2, a horizontal section. c

A represents the upper, and B, the lower part of the casing, between which the wheel C is placed and moves.

Around, and close to the outer rim of the wheel C, between the casings A and B, are pivoted the inner ends of four curved gates, D D, which, when closed, completely encircle the wheel, and shut o' the water, each one thus forming one-fourth of a circle, and, by their' peculiar construction and arrangement, also serve as a scroll for conduct-ing the water to the wheel, whether they are opened much or little.

The buckets E E, of the wheel, are each shaped on a circle of three-fourths the diameter' of the inside face of the wheel, and in length, one-thirteenth of thecir- They are set, so that when the outer edge is at an anglel of ninety degrees, the

inner edge or issues touch an angle of one hundred and sixteen degrees from the centre.

From the outer edge of each of the scroll-gates D, an arm, G, extends upward, above the upper casing A, and is, at its upper end, connected with a rackbar, H,vwhich rests upon the upperside of said casing, and gears with apinion, I, secured to a collar, J, which is placed loosely upon the wheelshaft.. There being four gates, D, there are consequently four of the racks, H, which are placed at ri ght an gles, and confined by suitable guides close to the pinion I.

A large cog-wheel, K, is secured to the collar J, which wheel gears with a pinion, L, upon au upright shaft, M, having its bearings in a suitable frame, N, om

the casing A, and. is operated by a wheel, O, at its Vupperend. Y

It will readily be seen, that by turning the shaft M, the racks H Hare all operated at the same time, and consequently the gates D D are all four opened or Vclosed at one operation. Y

Having thus fully described my invention,

Whatl claim as new, and desire to secure -by Letters Patent, is-

1. The combination of wheel C and gates D D, when said gates aureconstructed and arranged to operate as and for the purpose set forth.

2. The combination and arrangementof the casing AB, 'wheel C, gates D D, buckets E E, racks H H, and pinion I, all constructed and arranged as described, substantially as and for the purposes herein set forth.

ln'testimony that I claim the foregoing as my own,

I aiiix my signature, in presence of two witnesses.

F. O. CLARKE.
