GAS-CHECK FOR BUNSEN BURNERS.

SPECIFICATION forming part of Letters Patent No. 732,981, dated July 7, 1903.

Application filed November 7, 1902. Serial No. 130,377. (No model.)

To all whom it may concern:

Be it known that I, LOUIS T. was, a citia t of a spring-pressed slide which may be moved to control the amount of gas which is per-.

mitted to flow into the burner, the improvement for the most part residing in the means for securing and adjusting the spring and slide to the burner-tube.

For a more detailed description of the best embodiment of .my invention known to me reference is to be had to the drawings forming a part of this specification, in whichi Figure 1 is an elevation of a portion of the tube and nipple provided with my improvement. Fig. 2 is a similar view of the same, taken at right angles to Fig. 1. Fig. 3 is a section on the line 3 3, Fig. 2, looking in the direction of the arrows.

partially closed. Fig. 5 is an elevation of the tube. Fig. 6 is a plan of the spring. Fig. 7 is a plan of the slide. of the spring. Fig. 9 is a plan of the screw plug at the bottom of the tube. Fig. 10 is an elevation, and Fig. 11 is a cross-section, of the same, taken on the line 11 11 of Fig. 10 looking in the direction of the arrows.

Throughout the various views similar reference characters designate similar parts. The lower portion of a Bunsen-burner tube is designated-by the character 1, and adjacent to the lower end of this tube are the usual 5 openings 2 and 3, through which air is admitted to the tube. These openings are substantially rectangular, except that the openings 2 are provided with enlargements 4. and 5 in their lower portions, forming the pro- " jections 6 and 7, as is clearly shown in Fig. 5. While I have shown and described two en- Fig. 4 is a View similar to Fig. 3, except that the slide is shown.

Fig. 8 is an edge View largements 4 and 5, it is not necessary to have more than one. Below the openings 2 and 3 are the internal screw-threads 8, which are indicated in dotted lines in Fig. 2. The upper portion of the tube is not shown, as that forms no part of my invention, which may be applied to any Bunsen burner or similar article, and I preferably apply my improvement to those Bunsen burners which are used with Welsbach incandescent gas-lamps.

The spring 9 rests against the shoulder 6 in the upper portion of the enlargement 4, and this spring is provided with shoulders or projections 10, which closely fit the bore of the tube, as shown in Figs. 3 and 4., and these shoulders divide the spring into portions of unequal breadth, the greater not exceeding the length of the enlargements 5, and the lesser closely fits the enlargements 4,-and in the center of the spring is a perforation 11. The spring 9 is a leaf-spring, which may be made out of any suitable material and is bent, as shown in Fig. 8.

In Fig. 7 is shown the slide 12, which is preferably made out of a flat piece of metal and provided with a central perforat-ion 13 and shoulders or projections 14. The shape of the slide is substantially that of the spring, except that it is straight and not bent and is longer than the spring, and the shoulders 14. on the same edge are nearer together than the corresponding shoulders 10 of the spring in order that the slide 12 may be moved in the direction of its length in the bore of the tube.

A screw nipple or plug 15 with threads 16 engages the threads 8 in the end of the bore of the tube 1. Below the threads 16 the nippie is enlarged at 17 to form the shoulder 18, o

against which the lowerend of the'tube rests, and its upper surface 19 is a plane which forms a bearing for the slide 12. In the center of the surface or seat 19 is an opening 20, which connects with the hollowinterior 21 of ()5 the plug, and on the walls of this interior are threads 22, which enable the burner to be secured to any suitable gas-fixture.

23 is a set-screw which engages the threads 16 of the plug or nipple 15, thus securing said nipple in any desired position.

The parts are assembled in the following manner: The spring 9 is passed into the enlargement 5 of the tube 1 until the shoulders 10 are clear of the projections 7 and then it is forced upwardly until it rests transversely of the tube against the projections 6, the'ends of the spring flaring upwardly and outwardly. The slide 12 is then inserted in a similar manner and moved upwardly until it rests against the lowerconvexed surface of the spring 9. The plug or nipple 15 is inserted and screwed to its proper position, as indicated in Figs. 1 and 2, thus securing all the parts in their proper positions, so that the openings 20 and 11 will always register, and the opening 13 may be moved either into or out of alinement with them, as shown in Figs. 8 and at, or into any intermediate position, thus forming between the slide 12 and surface 19 avalve which will regulate by the size of the opening the amount of gas that enters the tube. The tension on the spring 9 may he adjusted by turning the plug or nipple 15 so that the slide 12 is forced into more or less intimate contact with the spring 9 and so moves with greater or less freedom on the surface 19.

An advantage of this construction is that the gas issues through the reduced opening with increased velocity, thus forming a jet which draws air with greater facility through the openings 2 and 3. This advantage would not be obtained if the passages were crooked or tortuous, as is the case where gas is regulatedby an ordinary cock.

While I have shown and described the best known embodiment of my invention, I wish it to be understood that many other forms are conceivable, which are covered in the following claims.

I claim- 1. In a gas-check or similar article, a tube, a spring laterally secured to the same, and spring controlled and laterally movable means connected with the spring to regulate the flow of gas through the check.
