My invention relates to a cigarette lighter, and the objects of my invention are:

First, to provide a cigarette lighter of class having novel telescopic fluid casing and cover means which automatically actuate the cover lid and spark wheel concurrently when said fluid casing and cover are telescopically pressed together;

Second, to provide a cigarette lighter of this class having novel cover lid opening means for exposing the lighter wick;

Third, to provide a cigarette lighter of this class having noval rack and pinion flint wheel actuating mechanism, combined with a novel over-running. clutch, which permits the rack and pinion to be in meshed relationship with each other at all times during reciprocal movement of the rack in both directions;

Fourth, to provide a cigarette lighter of this class which is very compact and efiicient;

Fifth, to provide a cigarette lighter of this class Which isvery neat, and in which the operating elements thereof are completely enclosed when the lighter is not in operation;

Sixth, to provide a. cigarette lighter or this lass in which the telescopic relationship of the fluid casing and the cover provides for large bearing area to, be engaged by the. fingers of the operator, whereby relative ease of operation of the lighter is afforded;

Seventh, t provide a cigarette lighter of this class having a novel over-running clutch; and

Eighth, to provide a cigarette lighter of this class which is very simple and economical of construction, eificient in operation, and which will not readily deteriorate or get out of order.

With these and other objects in view, as will appear hereinafter, my invention consists of certain novel features of construction, combination and arrangement of parts and portions, as will be hereinafter described in detail and particular- 1y; set forth in theappended claims, reference being had to the accompanying drawings and to th characters of reference. thereon, forming a partof this application, in which:

Fig. 1 is a top or plan view of my cigarette lighter, showing the same in closed position; Fig.v 2 is a side elevational view thereof; Fig. 3 is, a side elevational view of the, lighter as shown in Fig. 2, illustrating the cover in compressed position and the lid open, and a flame issuing from the wick of the lighter; Fig. 4, is a vertical sectional view of the lighter, showing portions fragmentarilyand portions further broken awaythis to-amplify .theillustration; Fig. 5. is a, ira

mentary sectional view, taken from the line 5-5 of Fig. 4; Fig. 6 is an enlarged fragmentary sectional view, taken from the line 6-6 of Fi 4; Fig. 7 is an enlarged fragmentary sectional view, taken from the line 'l----'! of Fig. 4; and Fig. 8 is a perspective view of the clutch operating spring of my cigarette lighter.

Similar characters of reference refer to similar parts and portions throughout the several views of the drawings.

The fluid casing l cover 2, lid 3, rack 4, pinion 5, clutch member 6, clutch spring I, spark wheel 8, rack return spring 9, plug l0, bushing Ii,

bolts

12 and 13, rack stop plate l4, and the lid spring 55, constitute the principal parts and portions of my cigarette lighter.

The fluid casing l is a substantially conventional cigarette lighter fluid casing, having a wick tube la projecting from the upper surface thereof, in which the wick lb is located. Centrally of the fluid casing I is the rack well lo, in which the rack 4 is reciprocally mounted. Secured to this rack 4 is the stop plate I l, held in place by the screw l3 internally screw-threaded into the endof the rack 4. This stop plate It engages an offset shoulder portion Id in the well lc for limiting the outward movement of the rack i, urged by the spring 9, which is abutted at its opposite end by means of the screwthreaded plug Hi, screw-threaded in the lower terminus of the well Ic, as shown in Fig. 4 of the drawings.

The rack 4 is fixed to the cover 2 for limiting the upward telescopic movement thereof relative to the casing and it is to be noted that other stop means may be provided for limiting the cover 2 relative to the casing I, in its upward movement, urged by the spring 9. Various means, such as stop screws, or the like, may be provided, if desired, so that the cover 2 remains in certain telescopic relation with the casing I when urged to its extreme travel by means of the spring 9, as hereinbefore described.

The rack A is provided with involute teeth do which engage the involute teeth of the pinion 5. Fixed to this pinion 5 is a clutch member 3, which may be optionally integral with the pinion 5', as desired. This clutch member 6 is provided with radially disposed buttress ratchet portions 6a, engageable with the angularly disposed end 1a of the clutch spring Lwhich is shown in perspective in Fig. 8 of the drawings. The opposite end 1b, of the clutch spring I is engageable with the radially disposed buttress ratchet teeth 8a 1 of the. spark wheel. 8 which may be: optionally integral therewith, as desired. The spark wheel 8 is provided with a substantially conventional external serrated portion 8b, engageable with the conventional flint, as illustrated by dash lines A in Fig. 4 of the drawings.

The pinion 5, clutch spring I and spark wheel 8 are all mounted on a hollow tubular bushing ll, supported by upstanding bracket I6 and I), which are maintained in spaced relationship to each other by the bolt l2, screw-threaded in the bushing ll, for holding the bracket portions la and If in certain spaced relationship to each other. The cover 2, as shown in Fig. 4, is substantially an inverted cup-shaped member, having a lid 3 pivoted thereon by hinge portions 3a, through which a pin 3b passes, all as shown best in Fig. 4 of the drawings. Secured on this pin 31) is a coil spring l5, which tends to hold the lid in closed position, as shown in Fig. 4.

The operation of my cigarette lighter is substantially as follows: When it is desired to ignite fuel in the wick lb and expose the flame thereon, as shown in Fig. 3 of the drawings, a person exerts pressure on the upper surface 211 of the cover 2, while exerting opposed pressure on the lower surface lg of the fluid casing I, which may be accomplished by pressing the cover and the casing intermediate the fore finger and the thumb of a persons hand. Telescopic compression causes compression of the spring 9 and concurrent rotation of the pinion 5 in its meshed relation with the rack 4, which reciprocates longitudinally of the well lc of the fluid casing l. The slot lh in the well lc receives the teeth 4a of the rack l, preventing rotation thereof, so that the teeth ta are always maintained in alignment with the teeth or" the pinion 5.

During rotation of the pinion 5 in a clockwise direction, as shown in Fig. 4 of the drawings, the clutch spring I interlocks the clutch portion 6a of the clutch member 6, and the clutch portion 8a of the spark wheel 8, causing rotation thereof and concurrent striking of the flint A, which ignites the fuel on the wick lb. During telescopic movement of the cover 2 over the casing l', the upper end portions of the brackets le and If force the lid 3 to pivot about the axis of the pin 32) into the open position as shown in Fig. 3 of the drawings, so that the flame burning on the wick lb is readily accessible to a person lighting a cigarette, and the flame is also exposed for receiving an adequate supply of oxygen.

When pressure is released from the casing l and cover 2, after the operation of the lighter has been completed, the spring 9 forces the rack l upwardly, together with the cover 2, until the stop plate it engages the ledge ld internally of the well lc or the fluid casing l, which limits the outward telescopic movement of the cover 2 relative to the fluid casing l. the position as shown in Fig. 4 of the drawings, the lid 3 is completely pivoted downwardly into its engaged relation with the cover 2 by means of the spring l5, operating about the axis of the pin 31) in the hinge portions 3a which pivotally connect the lid 3 with the cover 2.

In the operation of the clutch spring 7 during return movement of the rack A, the opposite ends la and lb are compressed toward each other longitudinally of the axis of the bolt l2, whereby the clutch is over-running, and the end portions la and lb of the clutch spring 1 alternately pass over the inclined buttress ratchet portions 6a and 8a of the clutch portions secured to the pinion 5 and the spark wheel 8. Thus, the rack 4 is main- As the cover 2 reaches tained in meshed relationship with the pinion 5 at all times, so that positive operation of the lighter is assured with each compressive movement of the cover 2 over the casing l, as hereinbefore described.

Though I have shown and described a particular construction, combination and arrangement of parts and portions, I do not wish to be limited to this particular construction, combination and arrangement, but desire to include in the scope of my invention the construction, combination and arrangement substantially as set forth in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
