WATERf-VVI-IEEL-GATE RING.

Specification of Letters Patent.

Patented Jan. 30, 1912.

Application led May 25, 1911. Serial No. 629,412.

T0 all whom t may concern.'

Be it known that LJoHN KINoAm, a cit-izen of the Dominion of Canada, residing at Vancouver, in the Province of British Golumbia, Canada, have invented a new and useful Vater-Wheel-Gate Ring, of which the following is a speciiication.

This invention relates to a means for controlling the flow of water to the nozzles of a multiple jet impact water wheel and is designed to control not only the passages to the nozzle vbut also the number of nozzles through which the water is directed onto the vanes or buckets of the wheel while maintaining a balance in the disposition of the jets on opposite sides of the wheel.

The invention is fully described in the following specification, reference being made to the drawings by which it is accompanied, in which: 1

Figure 1 is a vertical section through the casing of a wheel rotatable on a vertical axis. Fig. 2, a horizontal section of the same, and Figs. 3 and 4 are developments of the rotatable control rings. Fig. 5 is a detail top plan view illustrating the ring adjusting means. In these drawings 2 represents the circular casing or nozzle ring of the wheel from which the nozzles 3 which may be integral with or removably secured to the casing, inwardly project at an angle approximately tangential to the path of the buckets or vanes of the wheel and 4 is the casing cover which has a bearing which with the footstep bearing, support the wheel shaft.

The outercircumference of the nozzle ring 2 is turned to receive a ring 6 with a ring 7 tted on the outside of it, the ring 6 being rotatable on the nozzle ring 2 and 7 on 6. Both the rings are provided with apertures 8 and 9 corresponding in number and dimension and registering with those of the nozzle ring 2. In addition to the apertures 8 and 9 each of these rings is provided with supplementary apertures 10 and 11 the number of which is any required fraction of the number of nozzles and equally distributed around the ring, so that when either ring is rotated to bring its supplementary apertures into use they-will register with certain of the apertures of the nozzle ring in the case of the inner ring 6 and with the apertures 8 in the case of the outer ring 7.

The developments in Figs. 3 and 4 show clearly the relation of the supplementary apertures to the full power apertures 8 and 9 of each ring. The drawing shows a twelve nozzlewheel and each ring 6 and 7 is therefore provided with twelve apertures 8 in one and twelve apertures 9 in the other, which apertures will register with one another.

If the gate rings are designed to control the wheel by cutting out, say one-third and one-half of its nozzles in use, then one of the rings, say the inner one, is provided with eight supplementary apertures 10 which apertures, in order to have them equally distributed, are arranged, see Fig. 3, in pairs interspaced between each alternate pair of the apertures 8.

The outerring 7 is provided with six supplementary apertures 11 which are pitched around the ring, see Fig. 4, one between each alternate pair of the apertures 9. These rings 6 and 7 are independently rotatable through an arc of `movement sufficient to bring the supplementary apertures to register with those of the nozzle ring by means of a segment of rack teeth 15 projecting upward from each ring, in the teeth of which mesh those of separate pinions 16 mounted on spindles 17 rotated by means of hand wheels 18. y

The water from the penstock or casing in which the wheel is placed will pass through all the nozzles 3 when both rings 6 and 7 have their apertures 8 and 9 in register with those of the nozzle ring.

By rotating the inner ring 6 to bring the apertures 10 to register while retaining the apertures 9 of the ring'7 in their original position registering with those 3 of the nozzle ring, water will be passed` to eight of the nozzles, or two-thirds of the whole number, or if the outer ring is moved to registerk it-s supplement-ary apertures 11 while the ring 6 has its full power apertures 8 in, register, the wheel will be served through six, or one-half of its total nozzles. Again, if the inner ring 6 is moved to bring its supplementary apertures in register and the outer ring 7 is moved to bring its supplementary apertures to register, the outer ring will cut out half of the supplementary apertures of the inner ring and the wheel will be served through four nozzles, or one-third of the total. Thus we have a range of control in a twelve nozzle wheel ranging through twelve, eight, six or four nozzles, and the circumference of the nozzle ring is so proportioned to the diameter of the nozzle inlets or the ring apertures that an interspace occurs between the apertures of the outer ring sufficient to cut off or close the apertures. entirely' when the ring is.ro- .tated' to bring the interspace over the aperture of the inner ring. Means is thus Vprovided by which a wide range of control j over the water admitted to the wheel is lobtained for not only may the gates to each vnozzle ,be uniformly graduated or cut ofi entirely but the number of jets which areby Letters Patent, is:

1. A means for controlling the admission of water to the jets of a multiple jet water wheel, said means comprising two rings one `rotatably iitting over the jet inlets of the wheel casing and the other over the ring yboth rings having through apertures corresponding in number and registeringwith the jet inlets and with them and with one .another each ring having interplaced between the aforementioned aperturessupplementary apertures distributed around the rings the number of the supplementary apertures in each being a different fraction of the number of jets and registering in pitch with certain of them and means forv independently rotatin each ring.

2. Means for control ing the admission of water to the jets of a multiple jet waterl wheel, Vsaid means comprising a ring rotatably fitting over the jet inlets of the wheel lcasing said ring having apertures corresponding in number and pitch with the apertures of the jets so as to register with them and in the interspace between these apertures other apertures in number less Ythan those jet apertures but registering with certain of them, a second ring rotatably fitting on the aforementioned ring and provided with apertures registering with those which correspond in number with the jet apertures and supplementary apertures fractionally less in number than either the jet apertures or the supplementary apertures of the first mentioned ring'and registering with certain of them and means for' independently rotating each ring.

3. Means for controlling the admission of water to the jets of a multiple jet water wheel, said means comprising two rings one `rotatably fitting over the jet inlet of the wheel casing and the other over the ring both rings having through apertures corresponding in numberfwith the jet inlets and registering with them and with one another each ring having interplaced between the aforementioned apertures supplementary apertures distributed around the rings the number of these supplementary apertures inv each ring being a'v different fraction of the number of jets and registering in pitch with certain of them, means for independently rotating each ring said means comprising a segment of rack teeth projecting from the edges of the rings and separate pinions the teeth of which mesh with those of the rack segments and meansfor independently rota-ting the pinions.

4. A means for controlling the admission of water toV the jets of a multiple jet water wheel, said means comprising a ring rotatably fitting over the j et inlets of the wheel casing-said ring having apertures corresponding in number and pitch with the apertures to the jets so as to register with them and in the interspace between these apertures other apertures in number less than those jet apertures but registering with certain of them, a second ring rotatably fitting on the aforementioned ring and provided with apertures registering with those which correspond in number with the jet apertures and supplementary apertures fractionally less in number than either the jet apertures orv the supplement-ary apertures of the first mentioned 'ring and registering with certain of them, the circumference of the rings being so proportioned to the vdiameter of the apertures that an interspace is provided between the apertures which is slightly larger than the aperture and means for independently rotating each ring. v

In testimony whereof I have signed my name tovthis specication in the presence of two subscribing witnesses.
