STEAM-PRESSURE REGULATOR.

To all whom it may concern.

Be it known that 1, Conn S'rronnn, a citizen of the United States, and a resident of Indianapolis, county of Marion, and State of Indiana, have invented a certain new and useful Steam-Pressure Regulator; and I do hereby declare that the following'is a full,

clear, and exact description thereof, refer-' ence being had to the accompanying drawings, in which like numerals refer to like parts.

The object of this invention is to improve This invention consists in combiningwith the reducing valve mechanism, connected with high and low pressure pipes, of auxiliary means controlled by fluid under pressure independently of the main pipe, and

means controlled by the low pressure steam' or fluid for controlling the pressure in said auxiliary means.-

vThe full nature of the invention will be understood from the accompanying drawings and the following specification and claim. p 7 I In the drawingsFigure 1 is a side elevation of the mechanism with parts broken away. Fig. 2 isa central vertical section through the timer for controlling the fluid in the auxiliary pipe. Fig. 3 is a side elevation of the reducing valve mechanism with parts in section. Fig. 4 is a central vertical section through the reducing valve and associated parts. Fig. 5 is an elevation of a modified form of the apparatus. Fig. 6 is'a vertical section through the portion shown at the upper left hand corner of Fig. 5.

There is shown herein a high pressure pipe 10 leading from any suitablesource of fluid under high pressure, connected with a low pressure pipe 11 by a reducing valve mechanism 12 which may be of the usual type. The valve stem 13 of the reducing valve extends upwardly and is mounted on a frame 14 secured upon the reducing valve mechanism, and in said frame a lever 15 is :tulcrumed at 16 between its ends, and at 17 is pivoted to thereducing valve stem 13, and at 18 is pivoted to a plunger rod 19. Therefore the lever 15 is pivoted to said parts on the opposite side of the fulcrum, as herein Specification of Letters Patent. Patented lay 17 1921 Application filed August 11, 1919. Serial No. 316,806. 2

shown, although this particular manner of mounting is not necessary. A weight 20 is suspended from one end of the lever 15 and '1 a weight 21 from the other end, which weights it is understood are adjustable by adding weight thereto or taking weight therefrom.

The plunger rod 19, see Fig. 3, extends into a cylinder 22 and is secured to thepiston 23, anolsaid cylinderis in connection with an auxiliary pipe 25 which runs to a regulating valve chamber 26 that is connectpressure .flows. This pipe 27 may be con nected with a city water supply system or any other water supply system where water is supplied under regular pressure independently of the means for creating the pressure in the high pressure pipe 10. The regulating valve 28 in thevalve chamber 26 is operated by a valve stem 30 that extendsin a diaphragm chamber 31 and is connected ed with a pipe 27, through which fluid under a with the diaphragm 32 therein. A weight regulating lever 3 is fulcruined at its end at 34: in'the frame 35 which carries the -diaphragm and said lever ispivoted at 36 to the valve stem 30 and carries the weight 37 on its outer end. i A pipe 39 extends from the lower side of the diaphragm chamber 31- to the'low pressure pipe 11.

The reducingvalve may be constructed as shown in Fig. 4 where the double valve 113 on the lower end of the rod 13 closes in the seat 11aas it moves downward and opens as it moves upward. The weights 20 and 21 and the mounting of the lever 15 is such that they willnormally hold the valve 113 open.

The operation is as follows: hen the pressure in the low pressure pipe 11 is too high, the fluid actingthrough the pipe 39, will lift the diaphragm 32 and open the valve 28and admit fluid under. pressure from the normal pressure pipe 2'? to the pipe 25 and that will actuate the plunger 23 and reduction valve 12 toward closed position and thus reduce the pressure in the low pressure pipe 11. On the other hand if the pressure is at any time too low in the low pressure pipe 11, the diaphragm will de:

the auxiliary pipe 25 and the plunger 23 and permit the latter to descend and cause correspondin movement of the lever 15 and reduction valve stem 1.3-,which opens the 'scend and close the valve 28 and shutoff I the passage of fluidunder pressure through 100 rod 18 and lever 15, which will moi ethe reduction valve a little more, thus increasing the pressure in the low pressure pipe.

In the modified apparatus, hown in Figs. 5 and 6, some of the parts are arranged to work oppositely to that shown in Figs. 1 to d, but to accomplish the same result in substantially the same way. There, as seen in Fig. 6, the valve 28 is below the port 128 instead of above it as in Fig. 2, and the lever 33 and weight 37 tends to hold the valve open and permit the fluid under pressure in pipes and 27 to pass through to the cylinder 22 and force the piston upward and tend to hold the right hand end of the lever 15 upward and thus hold the reduction valve 118 upward andopen. With this arrangement the maximum pressure of the water acts normally on the pis ton 23, while in the construction shown in Figs. 1 to I} the minimum pressure of the water acts normally on said piston 23. Therefore, in this modified form, the reduction valve is caused to move to a closing position when the pressure of water in pipe 25 1s dinnnlshed so as to allow theweighted end 21 of lever 15 to descend.

In order that the modified form may work as above explalned, the fulcrum of lever l5v is changed to the opposite side of rod 13,

from that shown in Fig. 3 to that shown in F i=g. 5, where it is fulcrumed on the rock- I. 1.1

mg bar 115 that is pivoted to the ear ii see Figs. 3 and 5. Thus when weight 21 descends, the reductionvalve 1s closed, while in F 1g. 3 such movement of weight 21 causes the reduction valve to open When the pressure becomes too high in the low pres. sure pipe 11 the dlaphragm of the regulator is forced upward and the valve 28 tends to close and reduce the pressure in the auxiliary pipe 25 so that it lets the piston 23 descend somewhat and cause the reduction valve to correspondingly move toward closing position. The low pressure in pipe 11 will cause the reversal of the parts just mentioned and thus tend to open the reduction valve.

Therefore, it seen there is more than one way to arrange the mechanism to operate as desired, the chief feature of the means being the utilization of the pressure in the auxiliary pipe to control the reduction valve in the main pipe. lVith this mechanism the parts will operate automatically to regulate the reduction valve, and do so silently andwithout any knocking or disagreeablecharacteristics during the operation thereof.

The lnvention claimed is:

The combination with high and low pressure pipes, and reduction valve mechanism connectlng them having an upwardly extending valve stem, .of a frame rigidly mounted on sald valve mechanlsm through which said valve stem reciprocates, a le ver fulcrumed between its end in said frame, a weight on each end of said lever, means for pivoting the lever to the valve stem for controlling it, a plunger mounted on the frame, a plunger rod extending therefrom' and reciprocable in the frame and pivoted to said lever for actuatlng 1t, an auxiliary pipe connected wlth said plunger for operating it by fluid under pressure therein independently of the high pressure pipe, and means controlled by the fluid under pressure in the low pressure pipe for regulating the pressure in'said auxiliary pipe.

In witnesswhereof, I have hereunto affixed my signature.
