2,795,945 SMOKERS LIGHTER August Coenders, Dusseldorf-Kaiserswerth, Germany Application May 31, 1955, Serial No. 512,248 Claims. (Cl. 677.1)
The present invention relates to lighters such as cigarette lighters and, more specifically, to lighters for liquid fuels, which are provided with a fiint, a friction wheel land a wick adapted to be lowered into a wick tube. This known type of lighters as heretofore customary has the drawback that the sealing stopper arranged adjacent the closure -spring is subjected to the heat of the ame tip when the lighter is lit. As a result thereof said sealing stopper becomes brittle and gets cracks after -a relatively short usage so that it will not properly seal any longer. This is the reason why the above identified known type of lighters operating with liquid fuel cannot be marketed without the insertion of absorbing material.
It is, therefore, an object of the present invention to provide a lighter which will overcome the above mentioned drawbacks.
It is another object of this invention to provide a 4lighter adapted to ybe operated with liquid fuel such as lighter fluid, and provided with a nt, friction wheel and a wick adapted to be lowered into a wick tube, in which the sealing plug or stopper will have a long effective life and will not be subjected to a harmful effect of the flame.
These and other objects and advantages of the invention will appear more clearly from the following specifica tion in connection with the accompanying drawing, in which:
IFig. l diagrammatically illustrates a section through a lighter according to the invention, but on lan enlarged scale, said lighter being in `open position.
Fig. 2 is a section similar to that of Fig. l but showing the lighter closed.
General arrangement The lighter according to the present invention which is provided with a flint and a friction wheel is characterized primarily in that the wick receiving tube is longitudinally displaceable and is provided with a lsealing ring or washer which, when the lighter is open, shuts off the supply of lighter fluid. A further feature of the lighter according to the invention consists in that the upper end of the displaceable wick tube is surrounded by a sealing stopper adapted to be engaged in a sealing manner by a closure spring.
When the lighter according to the invention is open, i. e. when the lighter is lit, the wick tube cannot receive any lighter fluid from the fluid container so that after a certain time the flame will die. On the other hand, when the lighter is closed, the wick tube is lowered so that the previous seal effective between the fluid container and the interior of the wick tube, while the lighter was open, is not effective any longer so that new fluid will have access to the wick. When the lighter is closed, the closure spring rests in a sealing manner against the sealing stopper surrounding the wick tube so that in this condition the tip of the wick is properly closed off toward the outside.
Structural arrangement Referring now to the drawing in detail, the lighter shown therein is in customary manner provided with a fluid-receiving container 1 having an opening 2 through which the lighter container 1 can be filled. The opening 2 is adapted to be closed by a threaded stopper 3 and a sealing washer 3u. In the interior of the container 1 there is provided a tubular member 4 the upper end of aired States Patent O Patented June 18, 1957 which carries a int 5 which latter is loaded by a spring 6 within said tubular member 4. The tubular member 4 has its lower end closed by a screw 7.
A friction wheel 9 is rotatably Imounted on a shaft or pin 8 above the flint 5, said friction wheel 9 being c onnected to the lid 10. The lighter furthermore comprises a leaf spring 11 adapted to cause the lid y10 to spring open and thereby to turn the friction wheel 9.
The -lid 10 is provided with a protruding tongue or nose 12 `adapted to catch below a displaceable tongue or handle 13 which latter normally abuts a pin 14. A spring 15 continuously urges the handle 13 against said pin 14. When the 'lighter is in the position shown in Fig. 2, i. e. when the lid is closed, it will Ibe evident from the drawing that as soon as the handle 'has been depressed to such an extent that the nose 12 is released, the spring 11 will cause the lid 10 to spring open.
According to the present invention, the wick tube `16 is longitudinally displaceable. To this end, the lower portion of the wick tube 16 telescopically engages a sleeve 17 connected to the container 1. A pressure spring .18 is interposed between the bottom of the sleeve 17 and the bottom of the wick tube 16 so as continuously to urge the wick tube to move upwardly. The upper portion of the wick tube `16 is provided with a sealing washer or ring y19 supported on the wick tube in any convenient manner for instance by a bead or flange 20. When the lighter lid 10 is open, i. e. occupies its Fig. l position, the sealing ring 19 rests against a flange 21 of a sleeve 22 which in its turn supports a sealing stopper 23.
The upper portion of the interior of the wick tube 16 houses the wick 24 which preferably `consists of nonburnable material as for instance glass fibers. This wick is by means of a thin metal sheet 25 or the like pressed into a spring 26 arranged in the interior of the wick tube 16.
When the lid 10 is closed, the respective parts of the lighter occupy the position shown in Fig. 2. As will be see from Fig. 2, in closed position of the lighter the flange 11a of the spring 11 has pressed the wick into the wick tube 16. -In lorder to prevent the wick itself from lbeing compressed, the pressure is conveyed to the wick `by means of the inserted metal sheet 25. It will also be seen from the drawing that, when t'he lid is closed completely, the flange 11a 4of the spring 11 rests upon the upper edge of the wick tube and presses the latter likewise downwardly. Thus, in fully closed position of lid 10, the flange 11a engages the sealing stopper 23, thereby completely sealing the fluid container toward the outside. In this position the fluid in the uid container 1 will have access to the wick. This is due to the fact that in fully closed position of the lighter, the sealing ring 19 has been lifted off from the flange 21 -due to the displacement of the wick tube 16. The fluid can now pass upwardly between said flange 21 and the seal-ing ring 19 as well as between the sleeve or bushing 22 and the wick tube so that the fluid can flow to the wick through one or more apertures 27.
If now the lighter is opened, the spring 18 pushes the wick tube 16 upwardly while simultaneously the wick 24 is moved upwardly by means of `spring 26. When the lid 10 springs open, the friction wheel rotatably engages the flint 5 thereby striking a spark which will ignite the fluid in the wick. When the wick tube 16 moves upwardly, the sealing ring 19 again engages the flange 21 so that the passage `of :fluid from the container 1 into the annular passage 30 between the sleeve 22 `and the wick tube 16 is effectively prevented. Consequently no fresh fluid can at this time pass through the apertures 27 to the wick s'o that aftcr the fluid in the wick has been used up, the flame wil-l automatically die. It is, of course, under- 's'to'od that lthe flange 21 of the sleeve l22 is fixedly connected in any convenient manner for instance by soldering to the eye 31 of the container 1 so that the sealing ring 19 during the upward movement of the wick tube '16 will hit a fixed abutment thereby arresting the upward movement of the wick tube 16.
In order to keep the heat of the flame away from the upper edge of the sealing stopper 23, it is advantageous to provide a dame shield 28 for instance in form of a iiat spring with a corresponding circular opening. This shield may be made of one piece with the spring as is shown in the drawing. When the lid 19 is opened, the spring or shield 28 moves upwardly from its position shown in Fig. 2 thereby shielding the sealing stopper 23. Due to the fact that the cool air passing to the flame ows below said shield to the llame, it will be -obvious that -at the same time the upper edge portion of the sealing stopper 23 is cooled.
A leaf spring 29 may be provided at the lower end of the wick tube 16 for engagement with the adjacent portion of the spring 26 for the wick, thereby anchoring the lower end of spring 26 in the wick tube 16. It it is desired to remove or replace the spring 26, it is merely necessary strongly to pull on the wick.
It is, of course, 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.
