GAS COCK OR VALVE.

Application illed Ivarch 22, 1926. Serial No. 96,516.

I This invention lrelates to gas-cocks or valves, such as used on gas stoves for turning on the gas at the burners. In cooking with such stoves, it` is frequently desired to use the largest possible flame of the burner for a short period, foiyexample, where a food'is toV be boiled for a short time and afterwards left to simmer. Gas-cocks have been patented heretofore which were soconstruc-ted as to enable the gas to be turned full on or partially turned on, but as usually constructed for this purpose, the plug of the gas-cock was not held against a stop when in the foff positiomthat is to say, such devices have been constructed in such a way that the lever or handle was left in an intermediate position when the gas was off and from this position, the handle could be t-urned'in vtwo direct-ions, in one of which the rotation of the plug was not the reason that the` plug is not up againstv a stop when it is in its off positioirand hence in using a stove with a gaseock of that construction, the cook must take care to leave the valve in the off positiointhat is to say, in a position so that no gas is leaking past the Valve. As is well known, the plugs of gas-cocks` frequently become very loose which renders them unsafe due to the danger of leaving them in a leaking position by a person who believed that he had left the gas completely turned off.

The general object of this invention is to produce a gas-cock which will perform the functions of the gas-cock described above, but constructed in such a way that it can be operated with safety.

Further objects of the invention will appear hereinafter.

The invention consists inthe novel parts and combinations of parts to be described hereinafter, all of which contribute to producean efficient gas-cock or valve. l

A preferred embodiment of the invention is descri'bed in the followingfspecication,

e `handle wasrotated in while the scope of the invention ispointed out 1n the appended claims.A

In the drawing:

Figure l is al front elevation of a gas` cock embodying .my invention.

Figure 2 is a horizontal section through the gas-cocky and showing the same in the offvpositioir This section is taken o n the `line 24V-2 of Figure l, looking upwardly.

Figure 3 is 'a view similar to Figure 2 Vbut showing the gas-coelrin the full on or completely open position."

i Figure 4 is a view similar to Figure 3`but Ashowing the gas-cock inits partially open position,v enabling the gas to be left partially on.

In practicing'my invention, I provide a body and a rotatable plug with cooperating gas ports; the body has a fixed stop which cooperates with a stop member which is."

mounted to move with the plug. In one position of the valve or plug, the stop inember` of the plug engages the fixed stop and stops the valve or-plug inthe olf position. yBy rotating the handle, the plug will ,be rotated in a direction to bring the gas cock' to its full onyposition with the gas orts in full communication;` and by rotatlng the handle further in the saine direction, the plug will come up against a second stop that stops the plug in a slightly open position suchV as will supply enough to letthe foodsimmer.

Regarding the invention from another angle, it may be saidthat I provide a handle forfthe plug which is in an intermediate position when the valve or gas-cock is full on and by moving the handle in one direction from this intermediate position, the plug will comeV up against a stop holding the valve turned off if rotated in the other direction, the plug will come up against a stop which` stops the ports in partial communication, that is, the valve is partially open.

Referring to the preferred embodiment of theinvention 'illustrated in the drawing, 1 indicates the body of the gas-cock which is provided with a rotatable plug '2 of common type and capable of being rotated by a handle 3. The body 'and plug have gas ports t and 5' which align with each other when the v gas-cock is inits ffull on position, as indicated in Figure 3.- l

a suitable point, the body of the valve Ali'l is provided with a lixed stop which may be in the form of a shoulder or radial face G. The plug 2 ot the valve is provided With a stop member or pin 7. lfilhen the gas-cock is in its ott position, as illustrated in Figure 2, the stop member or pin 7 is up against the shoulder 6.

lWhen the gas-cock is in its full on position, as illustrated in Figure 3, the plug is not up against a stop but is in a position such that the pin 7 is at an intermediate point between the stop G and a second stop or shoiilder 8 carried by the valve body at a` point beyond the location ot the stop pin 'i'. ln other Words, in turning the valve on, the handle 3 is .moved in the direction indicated by the arrow' in Figure 2, until the handle arrives at the position shown in Figure 2. ln order to partially close the valve, the handle should be rotated further in the same direction until the stop pin i' strikes the shoulder 8. ln this position, the valve will be partially on, that is to say, the gas ports will be in partial. communication, as illustrated .in Figure it.

A gas-cock or valve having these vfeatures ot construction is safe when handled by a child or a careless person because i turning the gas oli from the full on position or :trom the partially on position, the handle is turned in the same direct-ion and it Would naturally7 be turned until it comes up against the stop G. The gas cannot be turned out and their on again unliglited as is possible with some gas-cocks having the partially open position. In other Words, with my corrst-ruction of gas-cock, When the gas is ott, the plug is up against a stop, and in turning the gas-cock to the partially on or simmering position for the valve, the handle must be rotated beyond the full on position.

Associated ivi th the stop shoulder 8, l provide a longitudinally adjustable stopmembei', the end 'tace ot which is engaged by the pin 7 carried on the valve plug. lhis adjustable stop is preterably in the torni of an adjustable set screw 9. This set screw is mounted in the casing or body l of the valve and its head is exposed on the exterior. One ot the advantages oli' this construction is that this stop can be adjusted while the gas is lit with a small simmering tlame; in other Words, by holding the pin 7 up against the adjusting screvv 9 and adjusting this screiv, the small tiame can be regu;

lated as desired While the flame is burning.

l'lvlhat l claim is:

l. ln a gas-cock, the combination ot' a body and a rotatable plug with cooperating gas ports, said body having a fixed stop on the said body, a single stop member mounted to move with the plug for engaging the iixed stop in the oli position ot' the gas-cock, a handle .tor rotating the plug in a direction to bring the gas-cock to its lull on77 position with the gas ports in full communication, said body having a second stop beyond the position ot the stop-member in the tull on" position of the gas-cool; and cooperating with the stop-member,when the plug is rotated further in the same direction to hold the gas ports in partial communication, to produce a small llame, said second stop-member being constructed to be adjusted longitudinally and mounted so that its end tace abuts aga-inst the stop-member on the plug, and accessible from the exterior of the valve to enable the size of the small flame to be regulated.

2. in a gas-cock, the combination of a body and a rotatable plug with gas ports, a handle tor the plug, said plug and body cooperating in the on7 position ot the handle to hold the ports in tull communication, a single stop-member mounted to move with the plug, said body having a fixed stop cooperating With the stop-member when the handle is moved in one direct-ion from the said on7 position into the oil position,

Vand a second relatively iixed stop to engage the stop member when the handle is moved in the other direction from the on position, and operating to hold the gas ports in partial communication, to produce a small tiame, said second relatively fixed stop colisisting ot a screw mounted in the valve casing ior longitudinal adjustment, with itsI end tace in position to engage the single stopniember carried by Vthe plug, and accessible troni the exterior ol? the valve to enable the size ot the small llame to be regulated.
