E. PROJAHN GAS LIGHTER Jan. 12, 1965 Filed Nov. 1, 1962 United States Patent 3,164,977 GAS LIGHTER Emil Projahn, Numberg, Germany, assignor to Gebruder Koliiseh, Nurnberg, Germany Fiied Nov. 1, 1962, Ser. No. 234,695 Ciainis. (Cl. 677.t)

The present invention relates to a gas lighter with a burner regulating screw arranged adjacent to the bottom of the lighter and covered by the outer jacket of the lighter. For purposes of adjusting the height of the flame of such lighter, as they are heretofore known, special tools as, for instance wrenches or screwdrivers are required. Such tools, however, are not always available.

It is therefore an object of the present invention to provide a lighter of the above-mentioned general type, which will have associated therewith an adjusting key for adjusting the height of the flame.

It is another object of this invention to provide a lighter as set forth in the preceding paragraph, in which the height of the flame can easily be adjusted from the outside of the lighter.

These and other objects and advantages of the invention will appear more clearly from the following specification in connection with the accompanying drawing, in which:

FIGURE 1 diagrammatically illustrates partially in view and partially in section a lighter according to the present invention with the adjusting key in pulled-out condition;

FIGURE 2 is a section through the burner pipe;

FIGURE 3 represents the adjusting key and spring pertaining thereto.

The present invention is characterized primarily in that the adjusting key is so designed that it can protrude from the jacket and can be returned into the jacket. The lighter has mounted thereon an adjusting key which, when in rest position, has its bit engaging an arm of a bayonet slot of the burner adjusting screw so that the key-head will be completely or nearly submerged in the jacket.

Referring now to the drawing in detail, the lighter illustrated in FIG. 1 comprises a fuel reservoir 2 which is flanged at 4 and 5 for holding the burner tube 3 soldered to reservoir 2. The upper and lower portions of the burner tube 3 are provided with

threads

6 and 7, respectively. A cylindrical tube 8 with a bore 9 is by means of a threaded extension 13 screwed into the burner tube 3. The cylindrical tube 8 has its upper end provided with a flange 10 on which is arranged a conical head 11. An annular seal 12 is interposed between flange 1i) and tube 8. Tube 3 has a portion of its length provided with a longitudinal slot 14 which communicates with the bore 9, the upper portion of said slot being provided with a lateral branch 15. The burner tube 3 has a transverse bore 16 communicating with the interior of the fuel reservoir 2. Mounted on the conical head 11 is a gas permeable pad 17 on which is provided a filter 18. In the upper portion of the burner tube 3, at threads 6, there is arranged a burner head 19 provided with an outer thread. This burner head '19 has a nozzle 20 which cooperates with a key valve '21 known per se, and located at the lower end of head 19. Valve 21 rests against a collar 22 of the lower portion of the burner head which latter rests against filter 18. The jacket body is provided with a bore 23 into which extends a displaceable adjusting key or member 24 3,lhi,77 Patented Jan. 12, 1965 ice having a knurled head 25 and a knurled bottom. Key or member 24 has a bit or pin 26 which latter engages

slot

14, 15. The upper end of key '24 has a stud 27 for receiving a portion of a spring 28 which latter is mounted in bore 9 above the adjusting key.

Spring 28 continuously urges the key 24 outwardly and pushes the same out of jacket 1 when bit 26 has been moved from slot arm 15 into slot 14 by a corresponding rotation of the key. Arm 15 serves as a stop-notch for bit 26 when key 24 has been pressed into the jacket.

The adjusting key 24 is directly connected to burner 20 inasmuch as when key 24 has been pulled down, its bit 26 engages slot 14 of tube 8. If head 25 of key 24 is turned, tube 8 is displaced upwardly or downwardly by means of thread 13 in burner-head 3 so that

pad

17, 18 will be compressed to a more or less extent and thus will become more or less gas-permeable, thereby effecting a control of the flame. These adjusting means are applicable in the same manner for lighters having a fixedly arranged fluid reservoir and also for lighters with interchangeable fluid reservoin It is, of course, to be understood that the present invention is, by no means, limited to the particular construction shown in the drawing, but also comprises any modifications within the scope :of the appended claims.

What I claim is:

1. In a lighter; a housing, a fuel reservoir in the housing, a tube in the housing extending from top to bottom thereof and internally threaded at its opposite ends, a burner head threaded into the upper end of the housing, means connecting the burner head with the reservoir and including a flame control element at the bottom of the burner head, a tubular adjusting element threaded into the bottom of the tube and engaging the flame control member and operable for adjusting the flame control member to adjust the rate of fuel supply to said burner head upon rotation of the said element, a key member reciprocably mounted in the adjusting element and having a first idle position wherein the major portion of the member is within the element and a second working position wherein the major portion of the member projects from the element, and pin and slot means in said member and element drivingly connecting the same while permitting axial movement of the member in the element.

2. In a lighter; a housing, a fuel reservoir in the housing, a tube-in the housing extending from top to bottom thereof and internally threaded at its opposite ends, a burner head threaded into the upper end of the housing, means connecting the burner head with the reservoir and including a [flame control element at the bottom of the burner head, a tubular adjusting element threaded into the bottom of the tube and engaging the flame control member and operable for adjusting the flame control member to adjust the rate of fuel supply to said burner head upon rotation of the said element, a key member reciprocably mounted in the adjusting element and having a first idle position wherein the major portion of the member is within the element and a second working position wherein the major portion of the member projects from the element, a pin projecting laterally from said member, and a slot in said element extending from near the lower end thereof upwardly along the element and terminating in a circumferential offset to receive said pin and lock said member in its said first position.
