4 Claims.

The present invention pertains to a novel smokers lighter of the type which burns a gaseous fuel such as butane gas.

One of the objects of the invention is to provide a manual adjustment for the discharge gas pressure. Another object is to provide an automatic adjusting mechanism for this pressure for lighters in which the gas is stored under high pressure.

In the accomplishment of these objects, a cupshaped housing is suspended from the top of the lighter body and has a porous disk laid in its bottom over an intake port. A chambered plug is screwed in the top of the housing and is adjusted to compress the disk to produce the desired discharg pressure. 7

The automatic control mechanism includes a seating member secured in the chamber of the plug a distance from the bottom thereof. An apertured disk above this member loosely guides a stem having a head adapted to close by gravity on the seating member. Low operating pressure in the lighter body is suflicient to raise the head and permit discharge of gas.

The top of the head carries a porous disk which closes against the apertured disk under high pressure in the lighter body. The porous disk is compressed in proportion to the pressure of the gas, and the discharge pressure is reduced accordingly. Thus, the discharge pressure is automatically reduced in proportion to the storage pressure.

The invention is fully disclosed by Way of example in the following description and in the accompanying drawings in which:

Figure 1 is a vertical section of the device;

Figure 2 is a vertical section of a modification;

Figure 3 is an enlarged view thereof;

Figure 4 is a similar view in a different position; and

Figure 5 is a cross section on the line 5-5 of Figure 3.

References to these views will now be made by use of like characters which are employed to designate corresponding parts throughout.

In the top 4 of a conventional smokers lighter is suspended a cup-shaped housing 2 having a gas inlet port 3 in its bottom. In the bottom of the housing is laid a porous disk t over which is laid a soft metal disk 5 known in the art.

In the housing 2 is screwed a plug 6 having a reduced end 1 bearing on the disk 5. The plug has longitudinal passage or chamber 8 communicating with a lateral passage 9 in the reduced end. The passage 9 connects the cham her 8 to the chamber Iii formed by the reduced end.

Th upper end of the chamber 8 receives an apertured plug l i The usual cap l2 has a rubber packing it that covers the plug III. The butane or similar gas in the body escapes through the aperture 3 and seeps through the disk i to the chamber IE3 where it expands. It then flows through passage s to the chamber 3 where it expands again. When the plug IN is uncovered, the gas flows through the restricted aperture l4 thereof and is ignited in the usual manner. The compression of the disks is regulated by screwing the plug in the body with a special tool.

The modification shown in Figures 2-5 is designed for gas stored under high pressure. A seat member !5 with a conical top It is fixed in the chamber 8 somewhat above the bottom thereof. In the chamber 3 is a. stem ll having at its lower end a head 59 with a rubber packing 2% adapted to engage the member I5 and cover the port 2! thereof. The stem is guided loosely in a pair of apertured disks 22 fixed in the chamber 8. Upon the head I 9 is mounted a compressible porous disk 23 adapted to close upward against the lower disk 2 2.

The high gas pressure in the body lifts the head IS and closes the disk 23 against the lower disk 22, as shown in Figure 4. The gas must flow through disk 23 to reach the chamber 8 and is reduced in pressure in flowing through the disk. The compression of the disk is proportional to the pressure of th gas, and the gas pressure is re duced correspondingly.

When the gas pressure in to raise the head is and stem merely rests on the member I 5. sure is sufficient to lift the head somewhat, but the reduction in pressure is not as great as when the disk 23 is compressed. The control of the outlet pressure is automatic, according to the compression of the disk 23.

Although specific embodiments of the invention have been illustrated and described, it will be understood that various alterations in the details of construction may be made Without departing from the scope of the invention as indicated by the appended claims.
