SPECIFICATION forming part of Letters Patent No. 34%,900, dated July 6, 1886. Application filed January 2,1886. Serial No.1S7A-i8. (No model.)
To all whom it may concern:
Be it known that we, GEORGE GALLAND and EMILE GnoUx, of Wilkes-Barre, in the county of Luzerne and State of Pennsylvania, have invented certain new and useful Improvements in Gas-Burners; and we do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings,forming a part of this specification, and to the figures and letters of reference marked thereon.
Our invention relates to that class of gasburners in which the gas is automatically cut off when the ame is extinguished, so that there will be no escape of gas into the room when the gas is blown out by accident or design; and it consists in a certain thermostatic device located within the burner and adapted to opcrate avalve, all as will be hereinafter described, and the points of novelty pointed out particularly in the claims at the end of the specification.
In the drawings, Figure l is a perspective view of a gas-burner constructed in accordance with our invention. Fig. 2 is a vertical sectional view thereof. Fig. 3 is a similar View of a modified form of burner. Fig. 4t is a side View ofthe central tube,within which the valveoperating devices are mounted. Fig. 5 is a sectional view showing a device for operating the valve from the outside. Fig. 6 is a perspective view of one of the thermostatic rods or strips for operating the valve.
Similar letters of reference in the several figures denote the same parts.
Heretofore burners of the class to which our invention belongs have been constructed with thermostatic expansive bars held above the burner and in direct contact with the flame of the gas, and when the iiame was extinguished the bar, by its contraction, automatically shut off the gas below the burner. Such constructions as these, it will readily be seen, are unsightly and require a great deal of nice fitting, packing, Src., in order to have them op crate properly 5 but all these defects and others are remedied by our invention, which consists, essentially, of an outside casing and an inside chamber, containing the operating mechanism, and having at its upper end the lava tip or burner proper, and a valve in said inner casing adapted to be opened'by a thermostatic rod or lbar and closedl by a spring, as will now be cxplained.
A represents the outer casing,adapted to be screwed onto the gasbracket, and having the appearance of an ordinary burner; B, the inm ner casing, consisting of a tube having at its upper end the ordinary lava tip or burner proper, D, to which it is secured, and which connects it to the casing A. At the lower end of this tube is a cap, E, secured thereto i by means of screw-threads, or otherwise, and at or near the center of this plate or cap is preferably provided a screw, e, having a broad head adapted to cover, when screwed in, two small pin-holes, c c', extending through this plate on either side ot' the screw-stem, as shown, for apurpose to be presently explained. F is a small valve placed in the side of the central tube, fastened by means of a screw, f, to a small spring, G, which is in turn secured to the tube B. The screw f extends through this valve and projects ashort distance toward the center of the tube, where it is adapted to be operated by the thermostatie rod or bar at certain times.
rlhe rod or bar G is constructed as shown in Fig. G, and consists, preferably, of a long piece of brass, y, broadened near one end and having the elongated opening or slot g' therein, the extreme end, however, being made quite small and screw-threaded, as shown, for the reception of a small nut, gt. This brass rod is preferably bent slightly near the slot,so as not to obstruct the passage to the burnertip, and to it is soldered or brazed a small piece 'of spring-steel, 7L, surrounding' the opening and. extending a short distance on either side thereof; or, if desired, `any two metals of different degrees of expansibility may be employed instead of the brass and steel. This rod G is secured at its upper end to the lava tip of the burner by having its reduced and screw-threaded portion inserted through a small perforation at one side of the slot in the tip, and the nut g2 applied thereto and tightened so as to fasten it securely, the steel portion of the rod being on the side toward the valve,so that when the rod is heated the brass portion expanding the most Will curve the bar to the position shown in dotted lines in Fig. 2, and its end coming into contact with the extended end of the screw in the valve will push the valve open and allow the gas to escape at the tipand be ignited.
Now, in order to have the rod heated and the valve opened when the lighted match is held at the end of the burner, the end of the rod is extended through the tip and proj eets in close proximity to the slit in the burner, and the rod being thus heated the unequal expansion of the metals will curve it and open the valve, as indicated, againsttthe tension of the spring and allow the gas to escape and be lighted, and after ignition the Haine will heat the bar sufficiently to keep it expanded and the valve open, but just as soon as the light is extinguished the rod,c ooling, contracts and allows the spring operating the valve to close the latter to its seat and shut off the sup ply of gas and prevent its escape into the room.
If desired, the therinostatic rod may be connected rigidly to the valve-stem so as to operate it in both directions, instead of allowing` the spring to close it alone, as described.
In Fig. 3 we Vhave shown a form of burner slightly Adifferent from thatA shown in Figs. l and 2, and consisting of two thermostatic rods, G G2`one on either side ofthe slitin the burner-tip. The lower. end of the longer of the rods G is adapted to come into contact with the pin and operate the valve,'asin the former construction, and it is provided about midway of its length with a short screw or piu, t', adapted to project through a perforation in the end of the rod G2, and having a head or nut upon its outer end, as shown. This rod Gr2 is similar to the rod G', except that itis about half as long,land will consequently move quicker under the influence of heat, and its lower end is provided with a perforatior, through which the pin i upon the rod G projects. The side f the rods on which the steel plate is secured being next the valve side of the tube B, it follows that when the rods are heated-they will both expand in the same direction, and if the shorter rod reaches the maximum amount of expansion first it will, by reasonof the head on the pin z', pull the rod G overand cause itslower end to operate to open the valve, while if the rod G only is heated it will move of itself and open the valve Without affecting the rod G2, thus always insuring the opening of thevalve when the match is applied to the burner-tip.
The lower end of the central tube,B, may, if desired, be held in central position and out of contact with the sides of the casing A by means of a perforated plate, H, secured to it in any suitable manner.
, Oftentimes it is undesirable to wait until sufficient heat has been applied to the thermostatie rods through their small ends at the end of the burner to open the valve, and we therefore provide the two small pin-holes before referred to in the end of tube B, so that a very small quantity of gas can escape-just sufficient to give a small flame at the tip that will heat ithe rods and open the valve, turning on the gas full. By means of the screw e the amount of gas passing through the pinholes can be regulated or shutl off entirely.
When Vit is not desired to have any gas escape when the stop-cock in the bracket is opened, and yet it is notv desirable to wait until the heat from a match has opened the valve, we provide a vdevice for the opening of the valve by the operator from the outside of the burner, and holding it open until the rods are sufiiciently heated by the gasiiame itself to act uponit. This device consists of a plate, I, secured to the tube B above the valve and projecting out slightly to one side thereof, and having at its lower end an armor projection, j, projectingunder the valve-spring,as shown.
J represents a pin or rod passing'through the casing A and irs inner end resting against the spring-plate I at the side of the tube B, as shown, tending to press the pin outward,'and having a head on its outer end,V by means of which it is operated to press the plate I inward, raise the valve from its seat, and permit the gas to escape and be ignited at the tip, as will be readily understood.
In order to prevent the escape of gas through the perforations in the side of the casing A through which the pin J passes, we preferably provide a collar, j', upon the pin, which normall y is pressed against the inside of the casing, making a tight joint therewith.
From the above description the operation of the device will be apparent.
W'hen the valve-operating pin J is used, the operator presses 4upon it, and, holding the match at the tip, ignites the gas, then holds the pin pressed in a few seconds until the rod or rods are heated from the gas-llame, when the valve will be automatically held open until the gas is extinguished, and then the rod or rods,eontracting,will allow the valve-spring to operate and shut off the supply of gas.
If desired, the valve-operating rod or pin may be dispensed with, and the screw in the end of the tube B screwed out, allowing a litl tle gas to pass out, as before explained,through the pin-holes; or both these forms may be dispensed with, and the heating of the rods from the match be relied upon, the latter being the simplest construction.
rIhe thermostatic rod constructed, as shown, with the broad portion where the steel piece is secured, and theprovision of the slot therein, greatly increases the sensitiveness of the rod by reason of the comparatively large amount of metal exposed, and causes the valve to close quite suddenly when the gas is ex tinguished.
The top D may be made of metal, if desired, in order to conduct the heat more rapidly to the rod G.
The whole device above described can be IOO IIO
