Figure 4 is a sectional view on an enlarged scale taken on the line 4-4 of Figure 2; and

Figure 5 is an enlarged view of a portion of the assembly shown in Figure 2.

Referring in greater detail to the drawing, in which like numerals indicate like parts throughout the several views, the cigarette lighter, according to the present invention comprises an upstanding casing having a vertically disposed partition 11 therein subdividing the interior of the casing 10 into a reservoir 12 and a pump chamber 13. The reservoir 12 is packed with a wick 14 and wadding 15 for absorbing a charge of liquid fuel.

The casing 10 has a top 16 on which is mounted a flint-striking mechanism 17 of conventional construction. The casing 10 has a bottom 18 which supports an upright hollow tube 19 within which is the conventional flint and spring for moving the flint into the mechanism 17.

A cup 21 rises from the bottom 18 within the pump chamber 13 and has an opening in one side thereof adjacent the partition 11 providing an outlet port for the chamber 13, the port being indicated by the reference numeral 22 and shown most clearly in Figure 5. The outlet port 22 connects the interior of the reservoir 12 in communication with the interior of the pump chamber 13.

A filler mechanism, indicated generally by the reference numeral 23, is positioned within the pump chamber 13 and comprises an upstanding hollow tube 24 normally within the chamber 13, the tube 24 having its upper end open and its lower end closed with ports 25 inwardly of the lower end of the tube 24, as shown most clearly in Figure 5.

The bottom 18 of the casing 10 is provided with an opening, indicated by the reference numeral 26, connect enlarged scale taken 2,818,717 iPatented Jarufl,

A vertically disposed spring 35, formed integrally with the casing 10, is arranged longitudinally of the bag 32 on one side of the latter intermediate the bag 32 and the lever 34. A pivot pin 36 has its ends journalled in the wall of the casing 10 and supports the lever 34 for movement from the full line position, Figure 2, to a dotted line position, in which the portion adjacent one end, indicated by the reference numeral 37, bears against the spring 35 and causes the spring 35 to collapse the bag 32 into the position in Figure 2 shown in dotted lines, causing the air to be dispelled from the interior of the bag 32. This movement of the lever 34 is accomplished by inserting a fingernail underneath the free end of the portion 38 of the lever 34 and pulling it to the dotted line position shown in Figure 2.

A fuel supply can is indicated by the reference numeral 39 in Figures 1 and 2, and has a well 41 adjacent the discharge opening 42 for holding a charge of liquid fuel.

In use, the lighter, according to the present invention, is filled with liquid fuel by manually actuating the lever 34 to alternatingly compress the bag 32 to drive the air therefrom, and with the lower end of the tube 24 submerged in a supply of fuel, release of the lever 34, so that the natural resiliency of the bag 32 causes fuel to be drawn up into the interior of the bag 32. Upon compression of the bag 32, the fuel will be expelled from the open end of the tube 24 through the chamber outlet port and into the reservoir 12.

It will be seen, therefore, that the tube 24 can be manually withdrawn from the interior of the bag 32 and inserted in the well 41 of the can 39 with the bottom 18 of the casing 10 adjacent to and spaced above the dis- 6 t charge opening 42. This will permit filling of the reservoir 12 with fuel without spillage, wastage, and without excessive exposure of the contents of the can 39 to the atmosphere. What is claimed is: a I
