GAS-BURNER.

SPECIFICATION forming part of Letters Patent No. 406,584, dated July 9, 1889.

Appncainned August 13, 1888. serial 110.282,524.

To all whom t may concern.-

Beit known that I, ALFRED P. JACOB, of the city and county of Philadelphia, and State of Pennsylvania, have invented an Improvement in Gas-Burners, of which the following is a specification.

My invention relates to gas-burners; and it consists of certain improvements, which are fully set forth in the following specification, and shown in the drawings which accompany it.

It is often very desirable at night, particularly in halls and the sick-room, to have a gas-burner so arranged that the full jet of gas can be instantly turned on and automatically lighted without the use of matches or other independent means of igniting. NVhen the gas is merely turned down low, it is in constant danger of being blown out by any slight draft, and unless it is turned down so low that this .is possible the room is not darkened. Many attempts have been made to accomplish this end, which have, as a rule, heretofore necessitated the operation of some mechanical means to ignite the gas after it has been turned on.

These mechanical means are more or less obj ectionable and cumbersome and prone to get out of order.

It is the object of my invention to accomplish the automatic lighting of a full jet of gas by the mere turning of the valve, without 1any other devices, to be operated by the hand.

`turned out the automatic valve in the burner operates to cause the auxiliary flame tobe once more ignited and ready to operate again to ignite the gas when it is again turned on.

The details of my invention will be more fully understood from the description of the drawings, in whiche- Figurel is a side elevation of myimproved gas-burner. Fig. 2 is a sectional view of the same through the line yy of Fig. Fig. 3 is a cross-sectional View through the line ac a: of

piece E is a valve F, with its open part downward. This valve F is provided with alongitudinal slot f, and through a hole ein the side of the cylinder E a pin G is inserted, to hold it within the cylinder and prevent it from turning. The slot f willl allow the valve to rise and fall. l

His a hole or passage-way in one side of the valve F. One side of the cylinder Eis partially cut away to form a passage-way between the cylinder E and the inner surface of the burner B, and opening into 4this passage-way is a hole or orifice .I through the cylinder. On the opposite part of the cylinder E is a hole K. The valve F is so supported 011 the pin G that normally the hole II is opposite and coincides with the hole K of the cylinder. llie burner B also has an opening l) at a similar point, so that there is normally a passage-way through the valve F, cylinder E, and burner B, as shown in Fig..2.

L is a small tube or auxiliary burner into which this passage-way opens.

INI is a cylindrical screen having a collar N, by which it is attached to the burner B. This screen M is open at the bottom to receive the tube or auxiliary burner L, and has an opening at the top, which is almost on alevel with the tip C of the burner. I prefer to construct this screen of fine wire-gauze.with a metal top and bottom, and to have it open at the rop only toward the sidenear the burner-tip C; but the details of this screen are not essential to my invention. Its only function is to protect the Haine against drafts and allow of a sufficient supply of air, and when protection of that flame is not necessary the screen may be entirely dispensed with.

Normally the valve F is suspended on the pin G within the cylinder E, and there is a IOO V3o will continue to flow to the burner B.

passage-way on one side through the valve, cylinder, and burner into the small auxiliary burner L, and the edge of the valve on the other side extends over and covers up the 5 opening J through the cylinder into the passage-wayII, leading to the main burner. \Vhen, however, the gas is turned on full, the pressure of the gas against the valve F is increased, and by this pressure the valve is raised, clos- Io ing the passage-way on the one side to the auxiliary burner L and opening that on the other through J and I to the main burner. These two passage-ways should be so located with reference to each other that the closing of the one is almost simultaneous with the opening of the other, or so regulated that the gas'has commenced to escape through the tip C before the auxiliary burner L is extinguished, and vice versa. Then the escaping` 2o gascoming in contact with that small flame is instantly ignited and the auxiliary jet is extinguished. p

It is apparent that the valve F must in practice be made sufficiently light in weight 2 5 to be instantly operated by the pressure of the gas, and while this pressure continues of sufficient strength (which of course depends on the amount of gas turned on by the main valve) the valve will be held up and the gas When, however, the main valve is partially closed,

so that the pressure of gas is sufficiently diminished, the valve F will fall, thereby closing the passage-way to the burner B just 3 5 aft-er opening that to the auxiliary burner L,

and the gas escaping from said auxiliary burner Will be ignited by the flame from the main burner B, which will then be extinguished. Of course if the main valve is to- 4o tally closed and the entirel supply of gas shut off both burners will be extinguished, and to prevent this happening accidentally I provide the main valve-cock with two projections or pins o o', or one long one in place of two, as is usual, having their operating edges arranged a short distance apart, so that on turning the cock in one direction the pin o will come in contact with the projection P 1 on the gas pipe or 1fixture, and thereby sup-Y Y, ply sufficient gas to the small auxiliary burner fL without operating the valve. If, however, it is desired to completely shut off the supply of gas, the cock O is turned in the opposite direction until the pin 0 comes in Contact 5 5 ,with the projection I),which closes the valve in the usual or present manner.

It will be seen that by my invention the gas may always be kept ignited at the auxiliary ,burner L, andfthat upon simply opening the oo'y main or supply valve the gas automatically operates the valve F in the burner and a full jet of gas is ignited at the main burner B. The screen M, as above stated, protects the little auxiliary iiame and prevents it from being extinguished by the drafts in the room, and at the same time readily supplies all the air needed.

The minor details here shown may manifest-ly be varied in a number of ways without in the least departing from the principles of 7o my invention.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-

i. The combination of a main gas-burner with an auxiliaryY burner opening therefrom,

a short inverted-cu11 shaped valve loosely held entirely within said main burner and free to move vertically therein, and passages to the main and auxiliaryburners controlled 8o by said valve, so that when the one is opened the other is closed. n

2. The combination of a main gas-burner with an auxiliaryburner opening` therefrom, a cylindrical chest held in said main burner and provided with passages leading, respectively. to the main and auxiliary burners, and a sliding valve loosely supported in said cylindrical chest normally open to the passage leading to the auxiliary burner and closed to that 9o leading to the main burner.

2:3. The combination of a main gas-burner with an auxiliary burner opening therefrom, a removable cylindrical chest held in said main burner and provided with passages leading,

respectively, to the main and auxiliary burners, and a sliding valve loosely supported in said cylindrical chest normally open to the passage leading to the auxiliary burner and closed to that leading to the main burner.

4. A gas burner consisting of a main burner, in combination with an auxiliary burner opening therefrom, and a valve operated by the pressure of the gas, consisting of a vertically-movable inverted cup, and a cylindrical piece within which said cup is supported and upon the sides of which it is guided, located within the main burner, and provided with openings, respectively, to said main and auxiliary burners, said openings to I io the main burner being normally closed and the opening to the auxiliary burner being normally open.

5. A gas-burner consisting of a main burner, in combination with an auxiliary burner open- 1 I 5 ing therefrom and arvalve operated by the pressure of the gas, consisting of averticallymovable inverted cup, and a cylindrical piece within which said cup is supported and upon the sides of which it is guided, provided with 12o passages substantially in opposite sides opening, respectively, into the main burner and into the auxiliary burner located within the main burner, the former of said passages being normally closed and the latter normally. 12 5 open when the supply is increased.
