Leners Patent No. 113,489, 'dared A911111, 1871.

`IMPROVEMENT IN I TURB-INE WATER-WHEELS.

The` Schedule referred, to invthes'e Letters Patent and making part of the sama.

To whom it may concern Be it known that I, MCKENDRE A. Bnooks, of La Forte, in the county of La Porte and State of Indiana, have invented a new and useful Improvement in 'lurbiue \Vater-\Vheels; and I do declare that the following is a true and accurate description thereof, reference being had to the accompanying drawing and to the letters of reference marked t-hereon and being a part of this specification, inwhiclw- Figure lis an elevation showing 'the `case and wheel 'in section.4

Figure 2 is a section on the line a: fc, iig. 1.

Like letters indicate like parts in each ligure.

The nature of this invention rela-tes to an improvement in that class of water-wheels which is provided with sliding-ring gate interposed between the buckets of the wheeland stationary chutes, and in the method of operating the saine. p

The invention consists in giving such a gate a downward movement in opening, whereby the 'water is directed. to the tops ofthe buckets in asolid column when less than a full gate is given; also in the novel and peculiar construction of the inechanisru for'operating such gates, as more fully hereinafter set forth.

In the drawing- Arepresents the case of my wheel, between the upper and lower portions of which are arranged the chutes B, rising irom the top and eenterof thc case A, and rigidly secured thereto in a hollow standard,

C?, provided with a screw-thread, D.

E is a Vertical shaft passing through the standard C and case A.

rlhis shaft is stepped upon an adjustable bearing, F, in the foundation-frame G, upon which the case A is rigidly secured.

E is the hub of the wheel, rigidly secured to the shaft E near its lower end, within the case A.

Radiating from this hub are buckets I.

J is a spider, the hub of which encireies the standard F.

Within this hub is placed a rotating collar, K.

L is a stud projecting from the hub ofthe spider J, through which is journaled the rod M. rlhe lower end of this rod is V provided with a pinion, N, which meshes with the teeth c of the collar K. lhe upper end of the rod M passes through the guide O, and is provided with a proper hand-wheel, I.

Projecting downward from the ontervends of the arnis of the spider J are the rods It, passing through the case A, as shown in iig. l.

S is a ring-gate, interposed between the chutes B and the buckets of the wheel. 'Io the flange b of this .gate are rigidly secured the lower ends of the rods It.

Ihe operation ot' this device is as follows:

y turning the hand-wheel I) to the left it will be seen that the collar K will turn down the screw I) of the standard, also carrying with it the spider J; and, by reason of thc connection between the spider and the gate by the rods It, the gate will also be moved downward, thus opening more orless communication between the chutes and the buckets when partizilly Y closed.

rlhe action of the gate iirtliis` .manner causes the water admitted through the chutes to strike the upper portion of the buckets of the wheel, acting upon the whole face of the saine before it can be discharged. By this means the full force of thelwater is obtained,

a portion cf-which would be lost if admitted at the iled.
