PORTABLE LIGHTER.

Application filed February 18, 1928. Serial' Ii'o. 255,354.

This invention relates to portable lighters, an object of the invention being to provide a.

portable lighter in which the several parts may beconveniently assembled, and worn or injured parts readily replaced.

A further object is to provide a lighter of this character in which a spring moved, spark throwing arm is held in inactive position by an improved construction and arrangement of post, having a partial-turning movement to release the arm and permit the latter to throw sparks and ignite a'wick.

This particular invention has more particularly to do with the details of construction and their assemblage to produce an efiicient mechanical device which is not liable to get out of order and which will most efficiently perform the functions for which it is intended.

With these and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts, which will be more fully l1ereinafter described and pointed out in the claims.

In the accompanying drawings- Figure l is a view in vertical longitudinal section through my improved lighter, showing the spark throwing arm in set or inactive position;

Figure 2 is an end View, looking at the right-hand end of Figure 1;

Figure 3 is a top plan view of Figure 1 Figure 4 is a top plan view showing the spark throwing arm released and in upright position;

Figure 5 is a view in'horizontal section on the line 55 of Figure 1;

Figure 6 is a perspective view of the plate 46;

Figure 7 is a view in side elevation of my improved pawl disk 12, the view of the disk being taken on the line 7-7 of Figure 2;

Figure 8 ,is a viewiin'side elevation of the spark throwin wheel 7, the View of the wheel being ta en on the line 8*8' of Fig ure 2. v v

1 represents thecasing of my improved lighter having top andfibottomplates 2 and 3 secured thereto and forming a container'efor fuel oil to maintain awick 4, saturated for ignition. The top plate 2 supports a spark throwing arm 5 and a post 6, which latter functions to hold the arm in inactive posi- 'tionand release the arm to ignite the wick.

The arm 5 above referred to may bestamped from sheet metal or otherwise formed so that the major portion of said arm threaded to receive a nut'll which secures the fork rigidly to the top plate.

A pawl disk 12 of spring metal is positioned beside the wheel 7 and hasa central opening 13 to receive the in 8, and has a slit 14 extending radially roI'n the opening 12, and the metal constituting one wall of said slit is flared outwardly, forminga pawl 15 which engages in recesses 16 in the side face of the wheel17. The disk 12 also has an angle arm extension 17 which engages under the arm 5 so as to compel the disk to turn with the arm.

It is of course to be understood that the recesses 16'and pawl 15 constitute a ratchet coupling means between the arm and the wheel 7 so-that when the arm swings upwardly the wheel is caused to turn with the arm, and when the arm is swung downwardly the pawl .15 will ride over the face of the wheel without turning the same.

A coiled spring 18 is located within the bifurcated or forked end of arm 5 and at one end engages said arm and at the other, end

this spring tends always to throw the arm to an upright position. a The base portion 10 of fork 9 is tubular i form and receives a tube 19, this tube having a reduced end 20 located in an opening in the bottom plate, 3 with the shoulder 21 formed by said reduced end resting against the inner face of plate 3 so as to hold the parts in proper assemblage.

Ascrew22 is screwed into the lower end of the tube 19 and countersunk in the bottom plate 3 and a follower 23 fits the tube and is movable therein. This follower' 23 and the screw 22 have headed pins 24 thereon on which a coiled spring 25 is set. This coiled into a threaded opening 29 in the bottom plate 3 with the head of the screw countersunk, as clearly shown in Figure 1, so that this casing 27 may be removed and new blocks of stone or alloy supplied as the other stones are worn As above stated, the major portion of the arm 5 is tubular in form, and in this tubular portion, which constitutes the free end of the arm, a bushing 30 is screwed and provides mounting for a catch pin 3l.- This catch pin 31 projects beyond the end of the bushing and the arm and is preferably rounded or beveled, as shown at its outer extermit-y,

and adjacent its inner end is formed with an annular shoulder 32 adapted to engage the inner end of bushing 30. v

A block 33 is fixed in the arm 5 and a coiled spring 34 is interposed between the block 33 and the shoulder 32 of pin 31 so as to exert pressure on the pin, normally projecting the end of the pin beyond the end of the arm, as shown in Figure The post 6 above referred to, which normally holds the arm 5 inv inactive or horizontal position, has a circular base portion 35 which is preferably milled or otherwise roughened so as to permit the-.same to be readily turned by the engagement of a finger therewith, and this base portion 35' has an annular groove 36 therein for a purpose which will hereinafter appear.

Theupper end-of the post 6 is made with a recess 37 to receive and accommodate the head 38 of a pin 39. The post 6 has a longitudinal bore accommodating the pin 39, and the base portion of said post has a recess 40 therein receiving the upper reduced end of a ournal pin 41, and said journal pin 41 has a screw-threaded recess 42 in its upper end in which the screw threaded lower end of the pin 39 is secured.

The journal pin 41 has rotary or partial movement in acylindrical bearing cup 43 projected into the casing 1 through an opening' in the top plate'2, and this bearing cup 43 has an annular flange 44 at its upper end resting within a recess 45 in the base of post 6 and also in-a suitable recess in the top plate 2.

The post assemblage, indicated generallv by the reference character 6, and including the post per se, pin 39 and the journal pin 41, turns as an entirety and is held against longitudinal displacement by means of a plate 46. This plate 46 has a recess 47 at one end bearing against the upper end of the base portion 10 of fork 9, and at its other end has a curved recess 48, and this recessed end 48 projects into the annular groove 36 in the base portion 35 of post 6.

The plate 46 also has an opening 49 therein through which a threaded nipple 50 of a tubular wick holder 51 is projected. This wick holder 51 supports the wick 4 above referred to and has a disk-like spanner receiving enlargement 52 thereon-which rests upon the plate 46, and, when the nipple 50 is screwed into the opening in the top plate -2 provided for the purpose, the wick holder will serve to secure the plate 46 against displacement.

The top plate 2 has a recess 53 therein ac-' commodating a spring 54, one end of said sprin bearing against a wall of the recess, and the other end of said spring projecting into a notch 55 in the base 35 of post 6, holding said post in normal position and adapted to return 'said post to normal position.

The arm 5 carries a cup or snufler 56 which is adapted to cover the wick 4 and extinguish the same when the arm is moved to horizontal position.

Referring again to thepost assemblage n Figure 1, it will be noted that the post has a recess 57 under the head 38 of pin 39 and that the latch pin 31 normally rests in this recess 57 to hold the arm inhorizontal position. The recess 57, indicated in full lines in Figure 1 and in dotted lines in Figures 3 and4,

is located directly under the head 38, and said head 38 has a recess 58 therein which registers with'one end of recess 57, but said recess 58 is normally out of vertical alinement with the pin 31 so that in order to release the arm 5 and allow it to function it is necessary to impart a partial turning movement to the post assemblage to bring the recess 58 into register with the end of pin. 31, allowing'the arm to swing upwardly and throw sparks to ignite the wick. When the post is released it will return to normal position and when the arm is swung downwardl the pin 31 will ride over the head 38 into t e recess 57 and be held in inactive position.

By reason of this construction of post assemblage I am enabled to employ a pin 39 having a head 38 which may be case hardened or otherwise rendered extremely hard to withstand the Wear to which it is subjected as it 'is of course to be understood that the head of the pin constitutes a rounded or beveled surface against which the latch pin 31 rides into its holding position, and there is necessarily a maximum of wear at this point and it is therefore desirable that the pin 39'be such that it will withstand the wear, and if it should wear it can be replaced at a very small cost.

It is to be'noted that the different parts of my improved device while capable of ready assemblage into a complete whole are equally capable of removal and replacement in the event of Wear or injury, and I therefore believe that I have produced a device which is not only most efiicient in its performance but is also as near mechanically perfect in design as it is possible to make the same, so that replacement can be furnished and the life of the device as a whole can be extended almost without limit. Various changes and alterations might be 1 made in the general form of the parts described without departing from my invention and hence'I do not limit myself to the precise details set forth but consider myself at liberty "to make such changes and alterations as fairly fall within the spirit and scope of the arm is adapted to be operatively engaged.

to hold the arm in inactive position.
