VALVE Filed June 9. 1950 Patented Apr. 3, 1934 UNITED STATES PATENT OFFICE VALVE Application June 9, 1 930, Serial No. 459,889

11 Claims.

My invention relates to valves, particularly of the type in which the valve element is oper'ated by manual depression against a spring and contemplates an improved construction wherein the i operating parts are sub-assembled in a unit inserted, as such, in the housing.

More particularly, my invention relates to the type of valve employed in connection with flash ignitersV for gas burners, in which a restricted by-pass for the gas maintains a small (pilot iiame and in which depression of an external button, manually, elects the flow of a considerably increased amount of gas in order to project the ame over the burner which it is intended to ignite.

My invention is illustrated in the accompanying drawing in which Figure 1 is an elevational view of the valveof my invention;

Figure 2 is an axial vertical sectional view thereof; and

Figure 3 is a view of a clamping ring which is employed.

The valve housing isillustrated at 4. It is ex? tended on both sides of a central body portion, the

extension on one side being provided with the tapered screw thread 5, to take an appropriate receiving opening in the gas manifold of the gas range. The other extension is internally screw threaded at 6 for the reception of the end of the pipe 7 which leads to the torch head.

'Ihe 4central body portion of the housing 4 is provided with a well bore 8, the axis of which is at right angles to the axis of the two extensions. It is this well bore into which the sub-assembly of operating parts, now to be described, is inserted. The well bore has portions of three diameters, to effect the formationof two shoulders, 9 and 10. The sleeve 11 fits withinthe intermediate diameter portion of the bore, and it is this sleeve which forms the main carrying member of the sub-assembly. The shoulder 9 is oblique, as shown, to.

t the chamfer at the lower end of the sleeve 11.

The sleeve l1 is provided with the axial bore 12 which is reduced at 13 for the reception of the valve sleeve 14. Below the portion 13 of the sleeve 11 the transverse bore 15 is provided andv and washer 20, surrounding the valve sleeve 14, is laid upon this packing. A compression spring 21 surrounds the valve sleeve 14, within the bore V12, rests upon the washer l20, and extends up to the sleeve 18.

An operating button 22 has the screw threaded stem 23.threaded into the upper end of the internally screw` threaded sleeve 18. Y

It will now be clear that the spring 21 normally maintains the valve member 17 closed against the 65 seat 16. This normally separates the lower portion of the well bore 8, which forms an inlet valve chamber, and which is connected by passageway 24 with the gas manifold, from the valve outlet chamber which comprises the transverse bore 15 70 in sleeve 11, and which, by way of the passageway 25 and the pipe 7, communicates with the torch head of the igniter. When the valve member 17 is depressed, by depression of the button 22, manually, gas from the manifold ows around the valve member 17, into the transverse bore 15 and then on to the torch head.

However, as before indicated, means is provided for ley-passing a small amount of gas to maintain a pilot -flame at the torch head. This is done by means of the axial bore 26 and the transverse bore 27 in the valve member 17, the bore 26 being controlled by a needle valve 28 which extends upwardly through the enlarged bores 29 and 30 in valve sleeve 14 and which is carried by the lower end of the stem 23 on the button 22.

Obviously, rotation of the button 22 will adjust the point of the needle valve 28 relative to the seat at the top of the bore 26 so that the amount of gas lay-passed may be adjusted.

The top of the needle valve 28 is lodged in the bottom of the stem 23 as followsz--The stem 23 is provided at its bottom with the axial socket 31, in which the upper end of the needle valve ts, and the needle valve is provided, near its upper end, with the annular groove 32. After the upper end of thev needle valve 28 is inserted in the socket 31, the lower end of the stem 23 is spun over, into the groove 32 as indicated at 33.

A short distance above the transverse bore 15, the sleeve 11 is provided with the external groove 34, and a split spring clamping ring 35, shown in Figure 3, is inserted in this groove. 'Ihe groove 34 is of such depth, and the clamping ring 35 is made of wire of such diameter that, when the clamping ring is in the groove, tightly embracing the bottom thereof, the external diameter of the ring is greater than the external diameter of the sleeve 11 at that point. A clamping nut 36 nts tightly around the sleeve 11, below the shoulder 37 thereon, this clamping nut having its internal diameter slightly enlarged to form a shoulder 38 resting on the protruding margin of the ring 35, as shown. The clamping lnut 36 is screw threaded at 39 to thread into the internally screw threaded greatest diameter portion of the bore 8, and a packing ring 40 is disposed between the shoulder 10 and the bottom 0f the clamping nut 36.

It will now be clear that the sleeve l1, valve sleeve 14, sleeve 18, packing 19, washer 20, spring 21, needle valve 28, and button 22 may be subassembled independently of the housing. These parts include all the operating parts. The valve sleeve 14 is inserted into the sleeve 11 from below, the packing, washer and spring put in place, and the sleeve 18 then is threaded into the upper end of the valve sleeve 14, this bringing the lower end of the sleeve 18 into the bore 12.` In this assembly, obviously, the spring 21 holds the valve member 17 against the seat 16. The button 22, carrying the needle valve 28, is then screwed into the upper end of the sleeve 18, this bringing theA lower end of the needle valve 28 into proper position relative to the seat at the top of the bore 26, the button 22 being turned to the proper position to maintain the proper by-pass.

'Ihe clamping nut 36 is then slipped upon the sleeve 11 from below, up to the shoulder 37, and the split spring ring 35 is then slipped over the lower end of the sleeve 11 upwardly until it snaps into the groove 34. This sub-assembly is then ready for insertion into the housing 4. The packing ring 40 is placed upon the shoulder 10, the sleeve '11 is inserted downwardly therethrough until the lower end of the sleeve engages ythe shoulder 9, the clamping nut 36 being brought down onto the top of the bore 8 and being screw threaded therein.

The clamping nut 36 is then tightened against the clamping ring 35, compressing the packing ring 40 to make a gas-tight lt. This assembles the entire structure. With the needle valve properly adjusted, a restricted amount of gas passes from the manifold, past the needle-valve 28, and on through the pipe 17 to the torchhead. This maintains a small pilot flame at the torch head. When a burner is to be ignited, the button 22 is depressed which permits the flow of a greatly increased amount of gaspast valve 17, whereby the name-at the torch head is projected over the burner to be ignited.
