IMPROVEM ENT IN sTEAM-PRE-ssu RE REGULATO Rs.
- Specification forming part of Letters Patent No. 219,178, dated September 2, 1879; application filed Q April 2l, 1879.
To all whom fit may concern i Be it known that l, CHRISTIAN CHARLES SCHMIDT, of the city and county of New York,
a State of New York, havev invented a new and Improved Steam-Pressure Regulator, of which the following is a specification.
Figure l is a vertical central section of my improved steam-pressure regulator. Figs. 2 and 3 are ldetail sectional views ofthe Slide- `valve used therein, showin g it in different po sitions. Fig. 4 is a sectional view of a modiiication` thereof.
' paratus 5 and consists" of several new devices for utilizing the elasticity of a diaphragm, and of other details of improvement, hereinafter Inthe drawings, the letterArepresents the steam-supply pipe, leading from the `boiler or reservoir into a bulb orenlargement,lB, into which enters a tube, C. The open end of this tube C, within the bulb B, maybe more or less closed by a suitable valve, D. It will be perceived that the tube C traverses nearly one-half of the bulb, so that it'will be surrounded by steannwhich arrangement is to enable the water of condensation to collect in the bulb and ilow off through the pipe A, instead of entering the pipe C. a
The pipe. G, or an extension thereof, reaches into a chamber, E, from the lower part of which a discharge-pipe, F, carries the steam to the engine orheating apparatus.
j The back of the chamber E is `formed by a iiexible diaphragm, G, which constitutes av partition between the chamber E and another.
chamber, H.
a j I is a spindle passing through the outer wall, a, of the chamber H, and through the ee'nterof the diaphragm Gr,as`shown. This spindle carries within the chamber E a slidetube or slide-valve, J, which extends over and embraces the pipe C, as shown. The end of the pipe C, within the chamber E, is closed, as shown at b,- but steam escapes from C into E through side. apertures, d d, formedy in the pipe C.
The pipeJ has similar apertures e e, which,
when in line with the apertures d, as in Fig.
l, allow awfree escape of steam from the pipe C into` the chamber E; but when the apertures d and e are entirely out of line, as in Fig.
2, the escape of steam from the pipe (J will be entirely prevented. If the apertures d e are but partly in line, as in Fig. 3, less 'than the full amount of steam will be able `to escape from the pipe C.
In `order to effect these variations of discharge, the pipe J is made capable or longitudinal motion by being screwed upon the spindle I at n,as shown.
On the spindle I is formed a collar, f, which is contained within the chamber H, and which is, by a spring, g, constantly `pressed against its seat h at the back of the diaphragm. Now, by turning the spindle I by means of a suitable hand-wheel, fi, the coll'arj1 will always remain on its seat, andthe only effect of the ro-4 tation will be to screw the pipe J forward or backward, and to thereby adjust the position of the apertures c, so as to attain the desired size of discharge-opening.
The rotation of the pipe J `is prevented by a pin, l, which projects fromY a sleeve, m, into `a straight slot of the pipe J. The sleeve m projects forward from the central bushing of the diaphragm and surrounds part oi the Spindle I.
If, after the apparatus has been set, the pressure of steam within the chamber E should exceed the desired limit it will move the diaphragm outward toward the chamber H, and
thereby, as the diaphragm pushes thecollar f, move the spindle I lengthwise, and cause the Same to pull the tubeJ outward and close the holes d c, as in Fig. 2.
Now,although the slide-valve J, which is controlled by the diaphragm, and nevertheless independently adjustable, is shown in form of a tube, I desire to have it clearly understood that the tubular form is not at all essential, and `that any other form of slide-valve will answer the purpose equally well. l
In Fig. 4 I have shown a modification, according to which the slidevalve J on the spindle I enters the fixed pipe C within the bulb B, so that the entire `adjustment may take place by means of the spindle I, the Valve D v1. The combination, in a pressure-regulator, 0i' the steam-pipe C, entering diaphragm-chainber E, with theA valve J, spindle I, and daphragin G, the spindle I passing through the diaphragm, all arranged so that the valve J is adjustable upon the spindleIindependently of the action of the diaphragm, substantially as herein shown and described.
2. The annular diaphragm G, combined with the spindle I, carrying the eollarf, and with the spring g and slide-valve J, said slide-valve' being capable of independent motion on said spindle, substantially as herein shown and described.
3. The combination of the chambers and H and intervening' diaphragm with the spint dle I, collar f, spring g, slide-valve J, and pipe C, substantially as herein shown and described.
4. The combination of spindle I, having collar f, with diaphragm G, sleeve on, pin Z, slide-valve J, and pipe C, substantially as herein shown and described.
