8 Claims.
This invention relates to catalytic lighters for cigars and cigarettes.
A general object of the invention is to provide such a lighter having improved characteristics facilitating its ease and reliability of operation. More specifically, objects of the invention are to provide a catalytic lighter, wherein the catalyst is constantly open to the atmosphere and is cut o from communication with the fuel supply during periods of nonuse, so that it is not subjected to saturation or smothering by the fuel and is always in proper condition for ready and reliable action.
Other objects of the invention will in part be obvious and will in part appear hereinafter.
The invention accordingly comprises the features of construction, combination of elements, and arrangement of parts, which will be exemplied in the construction hereinafter set forth 20.- and the scope of the invention will be indicated in the claims.
For a. fuller understanding of the nature and objects of the invention reference should be had to the following detailed description taken in connection with the accompanying drawing, in which: Fig. 1 is a vertical sectional view taken through the center of a lighter embodying principles of the present invention, and showing it in the nonoperative position which it assumes during periods of non-use;
Fig. 2 is a vertical sectional view corresponding to Fig. l but showing the lighter in its operative position; and
Fig. 3 is a horizontal sectional view taken substantially along line 3-3 of Fig. 1.
The present lighter is preferably of the catalytic glow type wherein a suitable catalyst, such as platinum oxide, is subjected to a draft of combined air and hydrocarbon fuel, whereupon it becomes incandescent. If such a catalyst is constantly exposed to the presence of the fuel, it becomes saturated or smothered and this greatly increases the difliculty of, or prevents securing the desired incandescence. Also, with some types of lighters heretofore in use, the catalyst has been encased with the fuel supply during non-use, and even though an effort is made to keep the catalyst and fuel supply separated, it has been found that there sometimes is a seepage of hydrocarbon fumes through to the vicinity of the catalyst with consequent condensation of liquid fuel on or near the catalyst. The present invention is intended to obviate these difliculties.
Referring more particularly to the drawing,
there is shown a lower casing element I0 of hollow thlmble construction which is internally screw threaded at its upper edge to receive a union I I. This union is in the form of a hollow sleeve having a downwardly extending portion I2 which 5 is externally screw-threaded for attachment to the upper end of lower casing I0, and an upwardly extending portion I3 which is similarly externally screw-threaded for screw attachment with an upper casing element Il. The union Il 10 also is provided with a plurality of airports I5 which are suitably spaced about its periphery and are located in extension I3 in position to be covered by upper casing element Il when the latter is screwed tight.
'I'hese described parts in eifect comprise a casing formed of telescopically related sections, the lower section comprising casing element I0 and the union II, and the upper section comprising casing element Il.
A catalyst I6 is coniined between a catalyst holder Il and a retaining disk I8 o1' mica or the like and this entire unit is tightly pressed into the upper end of casing element I 4 so that it in effect becomes a single unit therewith. The cat- 25 alyst may be of any suitable form, being illustrated in the present case as a perforate block of platinum oxide, although other suitable forms and materials are contemplated. A split ring I9 underlies the holder I1 and aids in keeping it 30 pressed tightly against the end wall of the upper casing element. This end wall is provided with an opening 20 which is in registry with the catalyst and affords access thereto for the end of a cigarette. The sides of this opening are prefer- 35 ably `beveled as shown to assist in guiding the end of the cigarette into igniting relation with the catalyst.
A hollow tube 2| is rigidly fastened to and projects below holder I'I, the open upper end of this 40 tube being spaced from the under side of the per forate catalyst as shown, in order to communicate readily with all parts of the catalyst. Tube 2| when the device is operative extends nearly to the bottom of lower casing element I0, in such 45 position that when the upper casing element I4 is screwed to its closed position, the lower end 22 of the tube engages a compressible block 23 of rubber or other suitable material which is seated on and may be regarded as unitary with the closed lower wall of casing element I 0. This cuts oi communication between the catalyst and the interior of the casing.
A fuel containing absorbent body 24 surrounds tube 2| and is clamped thereto between holder 55 I1 and a washer 25 which is screwed to the lower portion of the tube. The absorbent body 24 is suiilciently compressed or felted to be self sustaining and is movable as a unit with upper casing element Il. The casing sections, when screwed together, provide a fuel chamber having its side walls spaced from body 24 so that when the parts are in the position of Fig- 2, air may pass from ports I5 to tube 2l as shown by the arrows.
In operation, the absorbent body 24 is impregnated with a suitable hydrocarbon fuel. For this purpose the upper casing element may be screwed entirely of! the union II so that the body 2l may be immersed in a fluid fuel. When the casing element Il has been returned to threaded relation with union I I, it may be screwed down tightly thereover until it covers and seals ports I5, while the tube 22 effects sealing contact with block 23, in which condition the lighter may be kept during periods of non-use. It will be seen that the catalyst is cut off from communication with the fuel supply, and, further, that even if fumes from the fuel source were to seep through into tube 2I, they may be freely dissipated without harmful smothering of the catalyst because such catalyst and the interior of the tube are always open to the atmosphere. When it is desired to ignite a cigarette, the casing element I4 is partially unscrewed so as to expose air ports I5 and to permit communication between the interior of the casing and tube 2|. A cigarette is placed closely adjacent the catalyst, and as the user draws thereon, a current of air is drawn through inlets I5 down around the fuel containing body 2l, where it mixes with fuel fumes, and thence upwardly through tube 2l into contact with the catalyst. The catalyst becomes incandescent in the presence of this combined fuel and air and ignites the cigarette.
It will be seen that there has been provided a construction which is extremely simple, sturdy and reliable, and which is well suited to fulfill its intended functions. Since certain changes may be made in the above construction and different embodiments of the invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense.
It is also to be understood that the following claims are intended to cover all of the generic and specific features of the invention herein described, and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.
