REGULATINGFVALVE.

SPECIFICATION forming part of Letters Patent No. 721,821, dated March 3, 1903.

Application filed Man, 1902.

To all whom it mag concern.-

Be it known that I, CHARLES O. MYERS, a citizen of the United States, residing at Perry, in the county of Dallas and State of Iowa, have invented certain new and useful Improvements in Regulating-Valves, of which the following is a specification.

The objects of my invention are to provide a valve of this class in which the passage-way through the valve is obstructed only by a plate having different-sized openings therein said openings capable of being successively broughtinto position coinciding with the passageway through the valve, whereby the greatest accuracy in regulating the capacity of the valve may be attained, and, further, to

provide simple and durable means whereby the valve-plate may be adjusted and to provide simple indicating means by which the operator may positively ascertain which one of the various openings is in position coinciding with the opening in the valve.

My invention consists in certain details in the construction, arrangement, and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which 7 Figure 1 shows in perspective the complete valve with a portion of a pipe connected with the union at one end thereof. Fig. 2 shows a vertical sectional view through one end portion of the valve-shell. Fig. 3 shows a vertical central longitudinal sectional view of the complete device. Fig. 4:" shows in perspective the plate detached from the valve.

Referring to the accompanying drawings, I have used the reference-numeral to indicate the body portion of the valve-shell. At one end thereof is an annular extension 11, designed to receive a wrench, and the shell is internally screw-threaded at 12. The other end portion of the shell is adapted to form a union by having its exterior screwthreaded at '13 and a union-fitting 14 connected therewith to receive a pipe 15, said union being of ordinaryconstruction. At the central portion of the shell is a vertical extension 16, which projects both above and below the body portion of the shell. At'its top is a detachable plate 17, and the interior Serial No. 96,270. (N0 model.)

of the extension is hollow, forming a chamber 18. At the rear of the chamber 18 is a partition 19 within the body portion of the cell having a comparatively small opening 20 therein. 7

. The reference-numeral 21 indicates a plate of a size and shape designed to enter the opening in the interior of the extension 16 and of such length as to be capable of considerable vertical movement therein. At the top of the plate 21 is a smooth flat surface 22, and beneath the surface 22 is a series of openings 23 of difierent sizes. At the front face of the plate is a series of cog-teeth 24 at one side of the row of openings 23. When this plate is arranged within the chamber 18, it may move vertically within, so that any one of the open ings 23 on the flat surface 22 may be brought into position in line with the opening 20, and when the fiat surface 22 is in line with the opening 20 the passage-way through the valve will be cut off, and when any one of the openings 23 is in line with the opening 20 the capacity of the valve will be limited to that of the opening in the plate 21 which is in line with the opening 20.

To operate the plate 21, I have provided a shaft 25, seated in an extension 26 on the side of the shell and having its outer end made annular at 27 to receive a key. On the inner end of the shaft is a pinion 28 to mesh with the cog-teeth 24. Obviously when the shaft 25 is turned the plate 21 will be moved vertically within the valve-shell.

I have provided means whereby the operator may ascertain with the greatest accuracy just which one of the openings 23 is in line with the opening 20 within the valve-shell, as follows: On the outer end of the shaft 25' is an indicator 29, and on the extension'26, surrounding the shaft 25, is a series of marks 30, one mark being designed for each of the openings 23 and one for the flat surface 22, said marks and indicator and pinion and teethplate being so arranged and proportioned relative to each other that when the indicator points to the mark corresponding to any one of the openings 23 on the fiat surface 22 said opening or fiat surface will be in position in line with the opening 20.

In practical use and assuming my improved Valve to be connected with water-pipes and assuming that it is desired to permit a flow of water through the pipes such as would pass through the smallest one of the openings 23 the operator need only place a key upon the annular end of the shaft 25 and turn said key to such position that the indicator 29 will point to the mark 30 corresponding with the smallest opening 23. Obviously the amount of water permitted to pass through the valve would then be limited by the size of the opening, and any one of the openings may readily and quickly be brought into position to coincide with the opening 20, or the flat surface 22 may be brought to this position, thus cutting off the flow of water through the valve. It is obvious, further, that the back surface of the fiat surface 22 may be made perfectly flat and that the interior of the extension 16 may also be made perfectly fiat, so that a watertight joint is provided between the back of the plate 21 and the interior of the extension.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States therefor, is

1. An improved regulating-valve, comprising a shell having an integral partition provided with an opening materially smaller in diameter than the interior of the shell, two hollow extensions on the shell one inner face of each extension being flush with one face of the partition, a flat plate having one smooth face resting against the partition and the flush faces of the extensions to form a watertight joint, said plate having a series of openings of graduated sizes, each susceptible of coinciding with the opening in the partition,

cog-teeth formed on the face of the plate opposite from the partition, a pinion contained wholly Within the shell, meshed with said cogteeth, and a shaft for the pinion mounted in the shell and projected through it.

2. An improved regulating-valve, comprising a shell having an integral partition provided with an opening materially smaller in diameter than the interior of the shell, two hollow extensions on the shell one inner face of each extension being flush with one face of the partition, a flat plate having one smooth face resting against the partition and the flush faces of the extensions to form a watertight joint, said plate having a series of openings of graduated sizes, each susceptible of coinciding with the opening in the partition, cog-teeth formed on the face of the plate opposite from the partition, a pinion contained wholly Within the shell, meshed with said cogteeth, a shaft for the pinion mounted in the shell and projected through it, an indicator on the shaft, and indicating-marks on the exterior of the shell corresponding to the openings in the plate, said marks and indicator coacting with the plate to indicate the position of its openings relative to the opening in the partition.
