My invention relates to a casing, receptacle, container or the like hereinafter generically termed a casing and adapted to con tain asuitable substance or material, as fuel which may be semiflsolid, jelly-like or of viscous consistency. 1 Y

My invention relates to a casing, as aforesaid, having a nozzle of novel characteristics adapting it for readily detachable association with a pyrophoric lighter casing.

Further advantages, objects and characteristics of my invention will become apparentfrom the following detailed description taken in'connection with the accompanying 1 drawings.

vMy invention resides in the casing, nozzle features, and in the combination of parts and features of construction of the character hereinafter described and claimed.

This application is a division of my application Serial N 0. 392,426, filed September 13, 1929. a

For an understanding of my invention, reference is to be had to the accompanying drawings, in which:

F'gure l is' an elevational view of a fuelcontaining casing as constructed in accordance with my invention;

Figure 4 is an elevational View, partly.

' broken away, and shows the fuel-containing casing after a quantity of fuel has been removed therefrom.

\ For purposes of explanation and to illustrate an important application of my invention, I have shown on the accompanyingdrawings an arrangement for introducing semi-solid or jelly-like fuel interiorly of the casing of pyrophoric lighting mechanism L which may be .of any suitable or desired character or type. As illustrative of one of the many forms of lighting mechanism to which my invention is applicable, I have shown the aforesaid lighting-mechanism L as comprising a casing '1 having 2 and a bottom wall 3. Projecting from the top casing wall 2 is the flameroducing mechanism per se which may be 0 any suitable type. As shown such mechanism comprises a member 4 reciprocatory, by manual action, to swing a lever 5 on a shaft or memher 6 carried by spaced standards projecting from said top casrn wall. The lever 5 carries the usual snu er cap which forms a, movable housing for the end of a wick tube 7 extending through the top wall of the casing 1. As is usual, a wick 8 disposed interior- 1 of said casing 1 extends through the wick tube 7 and projects slightly therebeyond.

a top wall When the member 4 is moved toward the top casing-wall 2, suitable spark-producing memhere, not shown, co-act to produce a shower of sparks which are directed toward the end of wick 8, the latter being exposed at this time due to movement therefrom of the aforesaid snuffer cap in response to pivotal movement of lever 5 as effected by the last described movement of member 4. 7

As is usual in the art, thecasing 1 constitutes a reservoir or receptacle for fuel which heretofore, usually, character, as benzine, gasoline, or the like. For introducing such fuel into the casing 1, it has been customary to. provide an opening or perforation 9 in the bottom casing wall 3, said opening being constituted by a sleeve-like extension, if desired, and being interiorly threaded for engagement with the exterior threads of a closure cap or plug 10. When the cap 10 is removed, a supply of fuel may be introduced into the casing 1 which may or may not, as desired, contain a body of suitable material for absorbing the fuel.

In lieu of the aforesaid liquid fuel and in accordance with my invention, there is utilized and introduced into the casing 1, or any other similar or desired casing, semisolid or jelly-like fuel of any suitable character' such, for example, as described in the co-pending application of Nathan Proper, Serial No. 342,306, filed February 23, 1929.

Semi-solid or jelly-like fuel of the character described above may be dispensed or has been liquid in sold on the market ina casin or tube T which, in the example illustrate comprises a fuel containin section or body portion the wall structure 0 which is deformable sheetlike metallic material closed or sealed at one end and, at the other end, comprising a sleeve-like extension or spout a servin as a nozzle or orifice having an opening 0 suitable extent for the passage therethrough of the semi-solid or jelly-like fuel upon application of pressure to said wall structure.

In accordance with my invention, the extension or spout a is of conical configuration converging in a direction leading from the body section of tube T and is formed of suitable impressionable material, as soft metal, and, throughout a great or the major length thereof, comprises a substantially smooth or even exterior surface. Immediately adjacent the end of said spout or nozzle a, suitable threads 5 may be provided for the rece tion of a closure cap 0.

ith the closure cap a threaded to the nozzle a, the fuel-containing tube T is dis-.

nsed or sold on the market in the condition illustrated in Figure 1. When the purchaser of such a tube T desires to refill or restock the casing of his lighting mechanism with fuel, the closure cap 10 of the latter is removed and the closure cap 0 of the tube T is likewise removed. Thereupon, the nozzle a of tube T may be inserted into the filling opening of the lighter casing and by suitably applied pressure axially of said tube T, while simultaneously rotatin the same, one or more threads (1 are forme on the spout a by die-like action of the interior threads 0 the opening (2 whereby the tube T is so held in assembled relation to thecasing of the pyrophoric lighting mechanism that ressure upon the wall structure of said tu e T forces fuel through the nozzle (1 into the lighting mechanism casing to charge the latter with a supply of fuel F, Figure 4.

After a suitable supply of fuel has been introduced into said last named casing, the tube T, by reverse rotation, may be unthreaded therefrom whereupon the respec-- tive closure caps may be placed in position, the cap 10 being threaded into the lighting mechanism casing and the closure cap 0 'ing threaded to the threads I). of spout a.

The tube T may now be'laid away until it is again desired to refuel the lighting mechanism whereupon the operation described above may be repeated, the previously formed threads (1 again serving to unite the two casings.

As herembefore stated, the spout a, preferably, has an exterior conical configuration and it is desirable that the inclination of the cone elements be relatively sharply inclined with respect to the cone axis. This arrangement is preferable because the spout a is thereby adapted to be associated with any i b such changes and modifications.

desired to be one of a pluralit of easing filling openings, even thou h suc fillin openings may have substantia y different iameters, as those of different makes, models or styles, those of lar r diameter, obviously, co-acting with an threading the spout a nearer the base of the cone and those of smaller diameter co-acting with and threading said spout a somewhat nearer the apex of the cone.

An added advantage of my invention resides in the fact that a single spout a may be adapted to be associated with a plurality of li hter casings even though the fuel openin s thereof have different diameters. This folows because the fuel opening of a certain diameter causes the formation of threads in one region along the spout a, and the filling opening of another diameter causes the formation of other threads in another region therealong.

By the above described manner of assembling the casin s T and L, a tight joint is obtained and, t erefore, leakage or wastage of fuel is obviated when transfer is effected from one casing to the other. The fuel comes into the casing L under pressure, the displaced air passin to the atmosphere by way of the wick tu e 7 To some extent, this action results in the transfer of fuel to the immediate vicinity of the wick 8 which absorbs the fuel in the lighter mechanism casing and causes the transfer of inflammable material to the region of combustion.

Although illustrated particularly in connection with the refueling of the casings of lighting mechanism, it shall be understood f that my invention is useful in other relations for effecting the transfer of material other than fuel in either direction from one casing to another when they are connected in accordance with my invention.

While the invention has been described with respect to a certain particular preferred exam le which gives satisfactory results, it will e understood by those skilled in the art after understanding the invention, that various changes and modifications may be made without departing from the spirit and scope of the invention and it is intended therefore in the appended claim to cover all What is claimed as new and secured by Letters Patent is:

A casing having a body section and a nozzle, threads on said nozzle for a closure cap, said nozzle adjacent the tip thereof comprising an unthreaded conical section of soft metal adapted to be externally threaded by the die-like action of the internally threaded filling opening of a pyrophoric lighter casing.

In testimony whereof I have signed my name to this specification.

LOUIS V. ARONSON.
