INVENTOR FRANK E R0556 BY @M ATTORNEYS Patented May 30, 1939 2,160,563 VALVE MANIFOLD Frank P. Roesch, Chicago, 111., assignor to The Standard Stoker Company, Incorporated, a corporation of Delaware Application August 10, 1938, Serial No. 224,104

4 Claims.

This invention relates to a valve manifold which consists of an integrally cast body, suitably cored to provide a plurality of passages each having a valve for controlling the flow of fluid therethrough. The invention is shown as applied to the fuel distributing jet of a stoker, although its use is not restricted to any particular installation.

It is an object of my invention to provide a simple and compact manifold that can be cast with a minimum of uneven shrinkage and that will not spring out of shape when the casting is cooled.

It is another object of the invention to provide a novel manifold thatcombines compactness with a maximum of strength and rigidity and that can be economically constructed.

Other objects and advantages of the invention will become apparent from the following description and theaccompanyingdrawings.

Referring to the drawings:

Fig. 1 is a fragmentary view in centralvertical section through a stoker embodying a pressure fluid distributing means, with certain portions of that Stoker in elevation, and in which construction, the novel manifold is employed;

Fig. 2 is a sectional view on the line 2-2 of Fig. 1 with the'manifold shown in elevation;

Fig. 3 is a sectional view of the manifold taken on the line 3-3 of Fig. 2; I

Fig. 4 is a sectional view taken on the line 44 of Fig. 3;'

Fig. 5 is a sectional view taken on the irregular line 5-5 of Fig. 4; and

Fig. 6 is a sectional view taken on the line 66 of Fig. 4.

Referring particularly to Figs. 1 and 2 of the drawings, a stoker discharge conduit is shown at I0, communicating with an opening II in the wall I2 of a furnace I3, such as that of a locomotive boiler. The discharge conduit I0 delivers fuel onto a distributing plate I4 disposed in the opening I I' and from which plate the fuel is projected into the furnace to the various parts of the firebed by blasts of fluid under pressure issuing from the pressure fluid jet member. I5.

The jet member I5 is provided with a plurality of separated chambers, such as I6, I'I, I8, I9 and 20, arranged to receive fluid under pressure from a suitable source ofsupply through the pipes IGa, IIa, I81, I91; and 20a, respectively. The blasts of .pressure fluid for projecting fuel from the plate I4 issue from the jet openings 2| of the jet mem-' ber I5, a plurality of such jet openings, preferably, communicating with each of the chamber I6, I'I, I8, I9 and 20.

The streams of pressure fluid issuing from the jet openings of the several chambers are directed toward predetermined areas of the firebed, and in 5 order to provide for adequate control of the intensity of these blasts for effecting proper control of fuel distribution, delivery of pressure fluidto the pipes I6a, Ila, I8a, I90. and 20a is controlled by valves, designated respectively as IE1), I'Ib, I8b, 10 I91) and 20b, each of which is manually controlled and carried by the manifold M. The manifold M receives pressure fluid from a suitable source of supply, such as the boiler of the locomotive, through the main lead 22. Within the body por- 15 tion 23 of the manifold'M, there is provided a chamber 24 receiving pressure fluid from the main lead 22. The pressure fluid passes from the chamber 24 into a cored triangular-shaped endless passage 25 formed in the manifold body 23 through an opening 26 which isv manually controlled by the main valve 21 carried by the manifold.

The pipes IGa, IIa, I8a, I91; and 20a are screwed into the manifold M and communicate with the 3 passage 25 through the respective secondary passages I6c, IIc, I90, I and 200 therein. The passages I6c,iIJc, I 8c, I90 and 200 are separated from the main passage 25 by the partition I 6d, IId, I 8d, I9d and 20d, respectively, and pressure fluid passes from the main passage 25 to the secondary passages through the openings IBe, I'Ie, I8e, I9e

and 29e, in the partitions IGd, I'Id, I8d, I9d and 2011, respectively, the size of the openings being manually controlled by the valves I 6b, I'Ib, I8b, I9b and 20b, respectively. The manifold M is secured to the locomotive backhead I2 by suitable means, such as the threaded bolts 40 passing through the web M and bosses 42 formed with the body portion 23 of the manifold. 40

Each of the valves, including the main valve 21, comprises a stem 29 threaded into a bonnet 29, the stem having a valve member 30 at its inner end and the valve handle 3| at its outer end. A valve'seat 32 is threaded into the body portion of the manifold between the passage 25 and each of the passages I60, I10, I90, I90 and 200, and between the chamber 24 and passage 25. Thus, pressure fluid will pass into the passage 25 and 50 the passages I60, I 'Ic, I 80, I 90 and 200 at various pressures determined by the setting of the valves.

The manifold embodying an endless main passage 25 is extremely compact and can be secured or interference with other equipment. The construction of the manifold insures against uneven shrinkage and undesired springing or warping out of shape when the manifold is cast and cooled.'

' I claim:

A valve body member having formed therein an endless main passage, said body member having a pressure fluid intake opening formed to receive a valve seat communicating with said main passage, said body member having a plurality of secondary passages, partitions within said bodyvmember' separating said secondary passages from each other, a partition separating said main passage from said secondary passages, said last-named partition being provided with a plurality of ports, each port beingjormed to receive a valve seat and providing communication between said main passage and one of said secondary passages, said body member being provided with a plurality of discharge openings, each of said discharge openings communicating with one of said secondary passages.

2. A valve body member having therein a triangular main passage, said body member having. a
