However, the prior art gas burner valve and oven control mountings have also proved to be dis advantageous in certain aspects.

In one prior art method for mounting gas burner valves and the like, the manifold was provided with a female thread. The burner valve or the like was provided with a threaded stem adapted to be threaded into the female threads in the manifold. This method requires some drilling and tapping of the manifold whereby metal chips are produced. The metal chips, of course, are not desirable and have to be removed.

In order to overcome the disadvantages of the abovementioned method, the method disclosed in US. Pat. No. 3,602,480 has been proposed. In this method the control device is secured to the manifold by resilient bracket means. One of the biggest disadvantages of this method is the fact that a gasket between the control device and the manifold is relied on heavily to prevent any gas leaks from the mounting to the atmosphere. In case a fire should occur burning the gasket, gas can leak into the atmosphere almost completely unrestricted creating a very dangerous condition.

SUMMARY OF THE INVENTION The present invention provides a useful mounting construction for securing a control device to a fuel supply manifold. The manifold for use with the present invention may be extruded or may be formed from rectangular tubing. Disadvantages of the prior art method are overcome by creating metal to metal contact between the control device and the manifold in addition to a gasket seal therebetween. Thus, should a fire occur burning out the gasket the amount of gas leaking'from the mounting is restricted by the metal to metal contact.

In a first embodiment of the invention, the manifold may be extruded, for example, such that a first side is formed on which the burner valves and other control devices are mounted, and second and third sides are formed adjacent to the first side which each have a groove or indentation running along the length of the manifold. The burner valves or the like have rigid fingers which extend from the valve around the first side of the manifold. A screw, threaded through one of the fingers and extending toward the manifold. is tightened to secure the burner valve or the like on the manifold.

In the second embodiment of the invention, the control device may be secured on a tubular manifold. The tubular manifold may be rectangular tubing having indentations formed at the proper place. The burner valve or the like is locked onto the manifold in the'same manner as before.

BRIEF DESCRIPTION OF THE DRAWINGS The invention will hereinafter be described in conjunction with the drawing figures in which:

FIG. I is a broken isometric view of an extruded manifold;

FIG. 2 is a view in partial cross section of a burner valve mounted on the manifold shown in FIG. 1 in accordance with the present invention;

FIG. 3 is a broken isometric view of a tubular manifold; and

FIG. 4 is a view in partial cross section of a burner valve mounted on the manifold shown in FIG. 3 in accordance with the present invention.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawing Figures and in particular FIGS. 1 and 2 there is shown a fuel supply manifold generally indicated by reference numeral 10 upon which there is mounted a burner valve 12. The manifold 10 may be extruded from an aluminum alloy, for example, so that it has a uniform cross section throughout its length. Other metal forming operations, although not practical for various reasons, may be used to form the manifold if desired.

The manifold 10 has a bore 14 through which fuel flows extending along its length. In addition the manifold 10 may be provided with a :rib 13 which extends along the entire length of the manifold and from which sections may be removed to provide a mounting position for the burner valve or other control device. Four sidewalls l6, I8, 20 and 22 define: the exterior shape of the manifold. Sidewall I6 is shown in the drawings as being flat but it may take on any convenient shape. Upper sidewall 20 is provided with a number of openings 24 extending into the bore 14, the number ofopenings being dependent on the number of valves and the like to be mounted. The sidewalls l8 and 22 are identical and each have a groove or indentation 26 running along their length. The indentations 26 form lips 28 which extend from the edge of sidewall 20. Finally a ring-like recess 29 may be machined in sidewall 20 concentric with opening 24 into which a gasket 30 is disposed.

Since the actual structure of the valve 12 or other control device other than the mounting bracket is not important to the present invention, the valve will not be described in great detail. It should be sufficient to say that the valve may have a rotatable shaft 32 which when rotated controls the flow of fuel from the valve inlet 34 to the valve outlet 36. The shaft 32 extends into the valve housing 38 which houses the valve components.

In accordance with the present invention the mount ing portion of the valve 12, generally indicated by reference numeral 40, includes the valve inlet 34 and a pair of

rigid fingers

42 and 44. Finger 42 has a portion 46 which rests on sidewall 20 and a portion 48 which wraps around flange 28 and into groove 26. Finger 44 has a first portion 50 which rests. on sidewall 20 and a second portion 52 which extends generally downward and toward the manifold as is shown in FIG. 2. A screw 54 is threaded through second portion 52.to secure the valve 12 to manifold 10 when tightened.

In mounting the valve 12 on the manifold 10, it can be seen that the screw 54 should be withdrawn from portion 52 as far as possible. Then the end 48 of finger 42 should be placed in groove 26, the valve seated properly on the manifold with valve inlet 34 and manifold opening 24 aligned. Then screw 54 can be tight ened to secure the. valve on the manifold.

In the embodiment of the invention shown in FIGS. 3 and 4, the same reference numerals will be used to indicate the same features as disclosed in the previous embodiment. Shown in FIG. 3 is a rectangular manifold 60 made from steel tubing for example. The manifold 60 has a number of

sidewalls

62, 64, 66 and 68. Sidewalls 64 and 68 each have at least one indentation 70 formed by conventional means which forms a flange or lip 72 extending from sidewall 66. Upper sidewall 66 has an opening 74 for each valve to be mounted on the manifold.

The valve mounting assembly shown in FIG. 4 is in everyrespect the same as that shown in FIG. 3 except for the gasket mounting in FIG. 4. In FIG. 4 the gasket 30 is mounted concentric with opening 34 in a small recess machined in mounting portion 40 of the valve. It should be understood that the gasket may be mounted in either the manifold or the valve mounting portion, depending on the type of manifold used.

From the above discussion of the invention it should be obvious to those skilled in the art that the present invention provides an improved seal between the manifold and the control device mounted thereon. Should anything happen to the gasket between the control device and the manifold, the metal to metal contact between the control device and the manifold will act to restrict the flow of fuel from the mounting.

It should be obvious to those skilled in the art that modifications may be made without departing from the true spirit of the invention which is defined in the following claims.
