PILOT-LIGHT VALVE.

Specification of Letters Patent. Patntd un@ 20 1911.

Application led November 17, 1909.` Serial No. 528,490.

To all whom 'it may concern:

Be it known that I, LAURENCE P. Diener, a citizen ofthe United States, and a resident of Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented certain new and useful Improvements in Pilot-Light Valves, of which the following is a speciiication, reference being had to the accompanying drawings.

This invention relates to valves having a by-pass for the passage of a minimum supply of illuminant to maintain a small jet burning while the illuminating burner valve is turned off, for the purpose of igniting the supply of illuminant ejected from said burner when the burner valve is opened.

The principal objects of this invention are, to provide a valve arranged to insure the ignition of illuminant when turned on, with an enlarged equalizing chamber from which the illuminant is distributed through the conduits to the burners;- to provide a tapering rotary controlling valve plug, normally maintained seated by gravity and opening into said enlarged chamber in the valve casing; to provide said casing with means arranged to support a plurality of conduits eontemporaneously controlled by said valve plug, and provided with passage- Ways in communication with said chamber independent of said valve plug; to provide means whereby said communication may be readily eiiected; and to provide a valve structure readily taken apart to aord access to the parts closed by the valve casing, and to the passageways extending through said casing.

This invention is further advantageous in that it provides means arranged to close communication through said passageways by shifting said conduit, or by substituting a conduit having an imperforate wall.

The form of this invention, hereinafter described, provides a valve casing comprising a body portion, and a cap therefor in threaded engagement therewith and affording an enlargedequalizing chamber for the convenient distribution of illuminant, said cap being supported by threaded engagement with the supply pipe and suspending the body portion of said valve, which provides a downwardly tapering seat for the valve plug, a plurality of radially extending threaded sockets for the gas conduits communicating with said chamber through -said tapering valve seat, a hollow valve plug Ahaving ports arranged to register with said conduits, said conduits being provided with `separate passages extending longitudinally therethrough, and connected with said chamber by passageways extending through said valve body to convey illuminant independplug, a sleeve threaded on said stem and secured thereto, a key threaded in said sleeve `in ammed relation with said stem, and means within said casing arranged to limit the movement of said valve.

This invention further includes the various novel features of construction and arrangement as hereinafter more definitely specified.

In the drawings, Figure 1 is a central vertical sectional view of a convenient form of this invention, certain of the parts being shown in elevation for convenience of illustration; Fig. 2 is a side elevation of said valve; Fig. 3 is a horizontal sectional view of said valve taken on the line 3 3 in Fig. 1; Fig. 4 is a central vertical sectional view of a modiiied form of valve taken on the line 4 4 in Fig. 5; and Fig. 5 is a horizontal sectional view of the valve shown in Fig. 4 taken on the line .55 in said figure.

In the form of this invention shown in Figs. 1 to 3, inclusive, the valve body 1 has the removable cap 2, forming the enlarged gagement with the supply pipe 4. Said body 1 provides the threaded boss 5 forming t-he annular shoulder 6, arranged to support the gasket 7, against which the edge 8 of the cap 2 bears when assembled in engagement with the threads of the boss 5, as shown in Fig. 1. y

The valve body 1 has the'downwardly tapering centrally disposed opening forming the valve seat 9, and a plurality ot' threaded sockets 10 communicating through the ducts 11 with said opening and arranged to receive the ends of the radially extending conduits 12 or 13, leading to respective burners of any convenient type (not shown).

The inverted, truncated cone-shaped valve plug 14, having the threaded stem 15, is rotatably seated by gravity in the valve seat 9 and has the central bore 16 in communication with the chamber 3 and provided with the ports 17 leading Jfrom said bore and arranged to register with the ducts 11 in the valve body 1 to open the passagefor illuminant from the supply pipe 4 to the burners ent of t-he valve plug, a stem for said valve i' chamber 3, suspended in screw-threaded enthrough the chamber 3, ports 17, ducts 11 and conduits 12 or 13. The rotary move* ment of the valve plug 14 is effected by the key 20, comprising the grip ring 21 and the shank 22 in threaded engagement with the sleeve 23, which is also in threaded engagement with the valve stem 15 and secured thereto by the screw 25 extending transversely through said stem and sleeve, as best shown in Fig. 1. Said valve plug 14 is limited in its rotary movement by the stop pins 26 and 27, arranged to alternately engage the respective opposite ends of the semiannular boss 30 extending upwardly from the upper surface of said valve body 1, in its respective open and closed positions. The valve plug 14 is conveniently adjusted axially in its seat 9 in the usual manner by the nuts 32 and 33 adjustably engaging the washer 34, carried by the reduced extension 35 of said valve plug 14, as shown in Fig. 1.

The form of conduits 13, as best shown at the right-hand side of Fig. 1, includes the longitudinal partition 38 forming the Separate passageway 39 arranged to convey illuminant to a pilot light adjacent to the burner (not shown), and said passageway communicates with the chamber 3, independent of the valve plug 14, through the by-pass ducts 40, which extend through the valve body 1 and may be conveniently tapped therethrough when said valve body 1 is sep arated from the cover 2, and, as may be observed, said ducts may then be readily cleaned of any obstruction which may be accidentally lodged therein. However, it may be noted that, as shown at the left-hand side of lFig. 1, the by-pass ducts 40 may be closed if desired by simply substituting for the conduit 13 the pipe 12, having the imperforate wall as shown, whereby said pipe or conduit is wholly controlled by the valve plug 14 and the ducts 40 are closed by said imperforate wall.

In the form of this invention illustrated in Figs. 4 and 5, the valve body 45 is provided with separate screw threaded sockets 46 and 47, respectively, for the main illuminant conduits 48 and by-pass ducts 50, which extend radially inwardly and then upwardly in communication with the chamber 3. In other respects the form shown in Figs. 4 and 5 is identical with the form illustrated in Figs. 1 to 3, inclusive.

I do not desire to limit myself to the precise details of construction and arrangement herein set forth, as it is obvious that various modifications may be made therein without departing from the essential Jfeatures of my invention as defined in the appended claims.
