VALVE AND VALVE-ACTUATING MEANS.

Specification of Letters Patent.

Patented Jan. 31, 1911.

Application filed August 23, 1909. Serial No. 514,183.

To all wlw/m 'it may concern:

Bc it lmoivn that I, CHARLES J. SIDDALL, u citizen of the United States, residing` at the city of Kalamazoo, county of Kalamazoo, State of Michigan7 have invented ce1-tain new and useful Improvements inlValves and Vi-Llve-Actuating Means, of which the following is a specification.

This invention relates to improvements in valves and valve actuating means.

The main objects of this invention are:` First, to provide an improved valve and means for actuating the same, whereby the same may be actuated from a distance. Second, to provide an improved valve mechanism for gas burners having a flash pilot in which the pilot flashing valve Will automatically close While the main burner valve remains open until closed through the actuating means. Third, to provide an improved valve mechanism embodying these advantages which is very simple and economical in strilcture and one which is not likely to get out of repair in use.

Further objects, and objects relating to structural details Will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the j following specification.

' The structure described constitutes one effective embodiment of my invention. Other embodiments would be readily devised by those skilled in the art.

The invention is clearly defined and pointed out in the claims.

A structure constituting an eective and preferred embodiment of the features of my invention is clearly illustrated in the accompanying drawing', forming a part of this specification, in which:

Figure 1 is a detail side elevation of a structure embodying the features of my invention, the pneumatic actuating means being shown in vertical section. Fig. 2 is an enlarged detail vertical section through the gas valve, taken on aline corresponding to line 2-2 of Fig. 1. Fig. 3 is a detail vertical section, taken on a line corresponding to line 3 3 of Fig. 2. Fig. l is a horizontal section takeny on a line corresponding to line 4&4 of Fig. 2. Fig. 5 is a vertical section of a modified construction in which the pilot flashing feature is omit-ted. Fig. 6 is a vertical section of another modification in which the valve proper is formed separately and attached to the valve diaphragm, the valve here shown is adapted for an inverted burner.

In the drawings, similar reference characters refer to similar parts throughout lthe several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing, 1 represents the gas supply pipe, the same being shown in the form of a Wall bracket. The burner 2 which is illustrated as the common form of open burner is preferably mounted on the gas valve casing 3, which is connected to the supply pipe by means of the nipple 4, having the supply passage 5 therein. The pilot burner 6 is mounted upon the valve casing 3. The main burner is connected to the valve chamber 12, by the passage 7, While the pilot burner is connected to the valve'chamber by the

passages

9 and 10. See lig 2. A. delivery passage 8 Which delivers to the valve chamber on the upper side of the pilot valve diaphragm 13 and on the same side thereof as the supply passage 5. The passage 9 for flashing the pilot opens into the chamber 12 on the same side thereof as the supply connections 8, as does also the by-pass passage 10, this by-pass passage is preferably controlled with the regulating valve 14 Which is adjusted to regulate the size of the normal pilot llame. When the passage 9 is opened, an additional supply of gas is admitted to the pilot to Hash the same. I therefore designate this passage as a flashing passage. The valve diaphragms 11 and 13 are concavo-convex in general form and are arranged to move oppositely in closing, so that by connecting a means for producing suction and pressure to the chamber 12 between the diaphragms the valves are simultaneously opened. The valve seats 15 and 16, respectively, for the pilot and main valves preferably project slight-ly into the chamber 12, as illustrated. In the structures illustrated in Figs. 2, 3 and 5, the valvesproper 11 and 13 are formed integrally with their diaphragms 11 and 13 respectively. The valve 11 is adapted to automatically close While the valve 13 is adapted to remain in either its open or closed positions until moved or actuated through the diaphragm actuating means. This result is accomplished by the form of the diaphragms. I preferably accomplish this by forming the main valve diaphragm with an inward curvature, although it may be accomplished by other means. This diaphragm is also preferably concent-rically stepped, as illustrated.

The means for actuating the valves preferably consist of a casing 17 having a plun vger seat portion 19 at its lower end, the seat portion being preferably tapered. lVithin the chamber is a diaphragm 2O which'is arranged to form a partition across the chamber. On this diaphragm is a plunger 21 having' a stem or linger piece Q2 thereon a1'H ranged through the outer end of the casing. The connecting tube 23 preferably opens into the chamber within the seat portion thereof, so that it is closed by the plunger when the plunger is in its inner position. This connecting tube 23 is connected to the valve casing` and through the passage 24 to the chamber between the valves. See Fig. S. The-casing 17 is provided with vent openings 25 at its outer end to permit easy adjustment of the plunger. I also preferably provide the casing with a relie-f passage 2G? which is controlled by the passage 27, the valve being arranged to open outwardly. The valve is held normally on its seat by the spring 2S. See Fig. 1. The advantage of this is to permit the ready seating of the plunger in case it is desired to open the valve, that is, the plunger can be moved to its inner position so that the valves are opened by the suction movement thereof.

In the modified construction shovvn in Fig. 5, the pilot flashing feature is omitted, so that the main burner valveis all t-hat is required. The valve here acts in the same manner as in the structure described in detail.

In the modilied structure shown in Fig. 6 the valve 13 is adapted to close with instead of against the gas pressure. This valve is preferably tapered and the valve seat 1G is also preferably tapered as shown. The valve diaphragm 13 in this structure is also adapted to remain in either its open or closed position.

lWy improved valve is comparatively simple in structure and is preferably made up of parts as is illust-rated in the drawings, for convenience in manufacture and assembling. As these details of structure form no part of the invention they are not specifically described herein.

I have illustrated and described my improved valve in the form in which I have embodied it. I am, however, aware that it .is capable of consider-able variation in structural details without departing from my invention, and I des-ire to be understood as claiming the same broadly as well as specilically.
