Patented April 2, 1907.
Application filed February 8, 1906.4 Serial llo. 300,077.
To all whom it may concern:
Be it known that I, LORENZ KRATZEN- STEIN, a citizen ofthe United States, residing at Buialo, in the county of Erie and State of New York, have invented a new and useful Improvement in Whistle-Valves, of which the following is a specification. Y
The object of my invention is to provide a whistle-valve of simplev construction which can be opened against a high boiler-pressure` 'with comparative ease.
In the accompanying drawings, Figurew 1 is a sectional elevation of the improved valve, showing the same closed. Fig. 2 is a similar view showing the same open. Fig. 3 is a perspective view of the main valve and its stem. Fig. -l is a cross-section of the main valve in line 4 l, Fig. l. Fig. 5 is a similar section of the auxiliary or relief valve in line 5 5, Fig. 2.
Similar letters of reference indicate corresponding parts throughout the several views.
A is the case of the valve, having the customary inlet-chamber Af and inlet connection ay and the outlet-chamber A2 and outlet connection a', with which latter the whistle (not shown) communicates.'
B indicates the usual diaphragm separating the inlet and outlet chambers and having the passage b, and b is a valve-seat, preferably of conical form, arranged at the inlet end of said passage.
C is the main valve, having a beveled face,
which normally closes against the seat b', and a hollow stem c, which extends upwardly through the diaphragm-passage b and the neck of the valve-case. This valve is constructed in the form of a piston, which slides in an auxiliary chamber D, arranged within the inlet-chamber A in line with the passage l), this chamber being preferably formed in a removable screw-cap D. The main valve is fitted snugly in the .auxiliary chamber, but'not so closely as to form a steam-tight joint. It is made hollow to form a longitudinal relief-passage e, which extends from' end to end thereof and to the lower end of which is appliedan auxiliary or relief valve F. This valve is considerably smaller in area than the adjacent rear end of c.' As shown in the drawings, the main valve is connected with its stem by radial longitudinal arms g, separated by ports g', through which the steam in the chamber D is allowed to escape into the outlet-chamber gitudinal slot h of the main stem when the relief-valve is closed, as shown in Fig. 1. This slot is formed in the projecting portion of the main-valve stem and receives the lower arm of an operating-lever I, to which the usual pull cord or cable i is connected. The stem of the relief-valve projects nor- `mally above the bottom of the slot h, so that upon pulling the operating-lever the same irst acts upon said stem and opens the relief-valve and then bears upon the bottom of the slot and opens the main valve.
The operating-lever is pivoted to a bracket I, attached to the top ofthe valve-case.
valve and holds the lsame in place. In the construction shown this spring is seated in a socket j, formed in the bottom` of the chamber D, and its upper end surrounds a stud projecting from the back of the relief-valve.
In the normal position of the parts of the valve the main and relief valves C F are closed, and the steam-pressure in the inletchamber A acts against the side of the main valve and also against its back andthe backof therelief-valve, inasmuch as the steam leaks around the main valve into the auxiliary chamber D.
Upon pulling the lever I to sound the whistle the stem of the relief-valve is depressed inde endently of the main-valve stem by the l'iirst portion of the stroke of the lever, opening said valve and allowing the steam in the chamber D to escape into the outlet-chamber through .the hollow main valve and the ports g and releasing the pressure from the rear side of the main valve. During the last portion of the stroke of the lever the same de resses the stem ofthe main steam to pass freely to the whistle.
Owingto the comparatively small areav of the relief-valve, the same can be opened with little effort, andowing to the comparatively close rit between the main valve and the wall of the chamber D the steam in the inlet connection cannot leak into the chamber D as rapidly asV the steam in the chamber is released when the relief-valve is opened. It is therefore only necessary to overcome the J is a spring which tends to close the relief- IOO valve, opening t e latterand allowing the tion this improved valve contains but few parts and can therefore be inaniiaoiured at comparatively sniall oost.
While lie valve is designed especially as a steam-whistle Valve, ity inay be 'used in oonn'ection with other appliances, if desired.
I claini as my invention# l.. The combination of a Valve-case liaving inlet and outlet chambers, a passage oonneoting'tlie sanie and an auxiliary chamber arranged Within said inlet-chamber, a inain Valve controlling said passage and fitted in said auxiliary chamber, said valve having a relief-passage connecting the auxiliary chain-- bei" with Jslie outlet-chamber oic t-lie case and l a hollowv stein extending through the wall of the caseI` a ieliel'evalve oi smaller diameter than the niain Valve arranged in the aiiXili l i i l i i I eeaeee iaiy olianiber controlling, said reliepassage and having a stein arranged in the stein of the iiiaiii Valve, and a common operating device aid stenis arranged to act upon the reliefvalve sieni in advance of the main-valve stein, substantially as set forth.
2. The combination of a valve-case having inlet and outlet chambers, a passage connecting the saine and an auxiliary oliainlier arranged within said inlet-chamber, a inain valve controlling said passage and 'fitted in said auxiliary eli-amber, said valve having a relief-passage connecting the auxiliary' chainlier with the outlet-chamber, a relief-valve of sinaller diameter than the inain Valve controlling said relief-passage, and a spring ar-v ranged in the auxiliary chamber for closing the relief-valve, and means for opening said valves, suliisantially as set forth.
