LIGHTER 2 Sheets-Sheet i24 Filed July 18, 1945 Patented Apr. 29, 1947 UNITED STATES PATENT OFFICE 7 Claims.

'This invention relates to cigarette lighters or the like and more particularly to lighters of the type which are provided with closures or caps which are adapted to be opened substantially simultaneously with the igniting of the wick.

The general object of the invention is to provide a novel and improved lighter of this class which is sturdy in construction and easy to operate, while at the same time being of a compact arrangement and smooth contour when closed, whereby it is convenient to carry and use as a pocket lighter for any occasion.

In its preferred embodiment the invention contemplates the provision of a lighter having a cover adapted to conceal and protect the operating mechanism when the lighter is not being used, and which is spring pressed toward open position, the cover being maintained closed by a spring-retained latch device. A knurled roller is set in one corner of the substantially rectangular lighter casing and a int wheel is adapted to be actuated thereby to shower sparks on the exposed end of a wick in the conventional way. However, novel means are associated with said roller to trip the cover or closure retaining latch when the roller is spun, so that the release of the closure and the igniting of the wick occur substantially simultaneously, and as a result of the same manipulative act.

Other objects and features of novelty will be apparent from the following specification when read in connection with the accompanying drawings in which one embodiment of the invention is illustrated by way of example.

Figure l0 is an exploded perspective view of the actuating roller assembly; and

Figure 11 is a horizontal sectional View through the roller and axle assembly taken on line II-II of Figure 4.

The illustrated example of the lighter embodying the novel features of the present invention is indicated generally by the reference numeral I0 and comprises a body housing or casing II of the general shape of a rectangular parallelepiped and a box-like cap or closure I2 which is hinged to the casing by means of the pintle I3 which passes through adjacent ears Il and I5 of the casing and cover.

The casing II includes side walls I'I and I8, a front wall I9, a rear wall 20, a top wall 2|, and a bottom Wall which is not shown in the drawings. The interior of the casing or housing is partly occupied by a block or frame 25 of irregular conguration, which contains or supports certain of the operative mechanism of the lighter. For example, the frame 25 is provided with a tubular recess 26 (see Figures 5 and 8) which is adapted to receive a compressible coil spring 21, upon the upper end of which is seated an abutment 28 having a ,guiding stern 29 received within the uppermost coils of the spring. The cover or cap I2 is provided with an abutment or projection 30 which is adapted to be in contact with the spring pressed abutment 28 at all times regardless of the angular position of the projection 30 corresponding to the pivotal position of the closure I2. It will be readily seen that the resilient pressure of the spring 21 urges the abutment 30 and consequently the cover I2 from the closed position shown in Figure 7 to the open position shown in Figures 1 to 4 inclusive.

The frame or block 25 within the casing II is provided with a narrow vertical chamber or recess 32 in which is housed a latch lever 33 which is pivoted upon the screw 34 and is provided with a nose portion 35 adapted to hook around the corresponding lip 36 formed on the inside of the forward edge of the cover I2. These parts are shown in engaged position in Figure '7 of the drawings. The lower downwardly extending end of the latch lever 33 is provided with an operating projection or abutment 38 and the upper end 35 of the latch is urged toward engaged position with the cover projection 36 by means of a leaf spring 40 which is seated within the rearward portion of the recess 32. The actuating abut- 3 ment 38 is adapted to be contacted and moved by operating means to be later described.

The portion of the interior of the casing Il which is not occupied by the frame I2 is adapted to be filled with cotton or other absorbent material saturated with fuel as indicated at 42, and a wick 43 leads from the fuel reservoir through an opening 44 in the upper wall 2| of the housing I9 and projects at 45 in position to be ignited by the sparks from the flint.

Secured as by means of the screw 48 to the frame of the lighter is a superstructure 50 which is adapted to support and guide the flint and flint wheel. A substantially cylindrical horizontal opening or passageway I is provided in the upper portion of the superstructure 50 to accommodate the flint 52. A pivoted element or lever 54 rotating upon the pintle 55 is provided with a nose portion 56 adapted to press against the rear end of the flint 52 and urge it forwardly toward the flint wheel. The flint projecting lever 54 is urged in a clockwise direction by means of the plug 51 seated upon the upper end of the compressed coil spring 58 contained within the bore 59 of the block or frame 25. A handle or trigger projection 68 extends from the lever 54 so that the lever may be retracted against the pressure of the spring 58 when it is desired to remove or replace the flint.

The flint wheel 65 is provided with a serrated periphery in the conventional way and is seated upon an upper surface of the superstructure 50 adjacent the flint 52. The flint wheel 65 is providedv with a polygonal bore through which the correspondingly shaped end 66 of the actuating shaft 51 extends. The shaft 6l is shouldered as at 68 and the flint wheel is secured in position by means of the screw 69. Thus, it will be seen that the flint wheel 65 is rigid with the shaft 61 and is adapted to rotate therewith.

The shaft 6T extends downwardly through an arcuate recess 'l0 formed in the casing, which recess is conveniently positioned along one corner of the casing Il, and the lower end of the shaft 61 is seated for rotation in the block or frame 25, as at 12. For the greater portion of the length of the shaft 61 it passes through a bore 'I3 in a double operating roller assembly 'l5 which is clearly shown in section in Figures 4 and 6 of the drawings and in perspective in -Figure 10. This V operating assembly consists of a lower knurled roller 'i6 and an upper knurled roller 11 separated by a washer 18. The two rollers are connected by'a pair of diametrically oppositely disposed rods or bars 80. The upper roller Tl is provided with a cylindrical recess 82 and the rods 80 may extend in grooves formed along the edges of this recess as clearly shown in Figure 1l of the drawings. The shaft 61 is provided intermediate its length with a shouldered enlargement 85 transiixed by a horizontal pin 86 the ends of which project radially from the enlargement 85. The enlarged portion 85 and the pins 86 occupy the recess 82 within the upper roller 11 and the arrangement is such that upon rotation of the roller 'l1 for less than a half turn, the rods 80 will strike the ends of the pin 8E and cause the shaft, 81 to rotate along with the operating roller assembly 15. This of course will cause the flint wheel 65 carried at the upper end of the shaft B1 to rotate against the flint 52 and shower sparks upon the upper end 45 of the wick and thus ignite the Wick and produce the flame indicated at 90 in Figure l.

A washer 9| having flat sides and having its ends notched as at 92 for receiving the projecting edges oi the rods 80, is placed around the upper end of the shaft 61 and dropped into the recess 82. This washer maintains the rods in their rigid fixed positions within the grooves adjacent the edges of the opening 82. This arrangement effects a rigid keying of the rods 80 so that they may exert a positive driving action upon the pin 86 and cause the flint wheel shaft to rotate upon the rotation of the actuating roller assembly 15.

The gap between the rollers 1S and 11 which is bridged by the exposed portions of the rods 80 is at the same level as the trigger or actuating projection 38 on the cover retaining latch lever 33 and this trigger 38 is disposed within the path of rotation of the rods 80, as most clearly shown in Figures 6 and 8 of the drawings. Thus whenever the roller assembly 15 is rotated (in a clockwise direction as viewed in Figure 8) one or the other of the rods 80 will strike the trigger or projection 38 and cause the latch lever 33 to rotate about its pivot 34. against the pressure of the leaf spring 40, in a clockwise direction as viewed in Figure 7. This will cause the latch 35 to be disengaged from the keeper 36 on the cover l2 and the spring 21 will effect a quick projection of the cover I2 to open position. At substantially the same time, the rods 80 will contact with the ends of the pin 86 carried by the shaft 61 and the Ilint wheel will rotate against the ilint to ignite the wick.

Thus, it will be understood that by means of the present invention a novel and ingenious lighter has been provided which possesses the convenient and time-saving feature of effecting in a quick and efficient way the simultaneous opening oi the lighter and igniting of the wick.
