Application December 13, 1946, Serial No. 369,995 9 Claims. (01; 67 4.1)
This invention relates to a pyrophoric lighter and has particular reference to a cigar or cigarette lighter and the like which can be actuated automatically by the Withdrawal of a torch member from its frame or casing.
The principal object of the invention is to provide a pyrophoric spark-producing mechanism of the aforesaid type which is mechanically simple, susceptible of economical and easy manufacture, possessing sturdy and rugged construction and which is quickly responsive to even a slight impulse.
Another object of the invention is to provide a lighter with an improved energy-storing mechanism for actuating the spark-producing means in which the energy is stored in response to the torch-inserting movement and which is released by the withdrawal of the torch member.
A further object is to provide a lighter having a casing and means for providing a direct flue throughout the same.
Various further objects and advantages inherent in the invention will become apparent from the following description which is taken in conjunction with the accompanying drawings.
It will be understood, however, that this description and disclosure is not by way of limitation but the invention may lend itself to a variety of expressions within the scope of the appended claims.
In the drawings:
Figure l is a vertical sectional view, partly in elevation, of a lighter according to the invention, showing the torch member in position for the energy-storing movement.
Figure 2 is a sectional view, also partly in elevation, showing the torch member completely inserted into the frame.

Figure 5 is a section taken along the line 5-5 of Figure 1.
Figure 6 is a detailed view of the spark-producing wheel.
Figure 7 is a sectional view similar to Figure 1 of a modification.
Figure 8 is a sectional view, partly in elevation, showing the lighter embodied in an ash tray.
Figure 9 is a top plan view of the device shown in Figure 8.
Figure 10 is a bottom plan view thereof.
Referring in greater detail to the drawings in which the same reference characters indicate the same or similar parts, the invention comprises a torchmember I0 having a handle H. The torch member is adapted to be reciprocated in the frame or casing I2.
The torch member I0 is hollow and is packed with wick-forming material IS. The torch member 19 is recessed adjacent the end and terminates in a nipple l4 through which the wick l3 protrudes. This nipple and wick are adapted to be received in the snufling box l5. In the modification shown in Figures 1 to 4, the snufiing box is made part of the casing or frame 12.
The handle II may be unscrewed for the purpose of charging the wick material l3 with fuel.
The spark-producing mechanism is arranged adjacent one side of the torch member ID. The spark-producing mechanism comprises a pyrophoric element 16 which is held in the tubular support ET. This support is mounted in the bracket is which is soldered or otherwise suitably secured to the frame 12. The spark-producing wheel i9 is freely rotatable on a fixed bolt or pivot 25 on the frame l2. The wheel I9 is provided with notches or cams 2| at one side thereof as shown in Figures 5 and 6 and which are adapted to be engaged by the pawl 22 of the crank member 23.
The crank member 23 engages the slot 24 of the projection 25. The projection 25 is in turn carried by the flanged sleeve or bracket 26 which is reciprocable on the support H.
The flanged sleeve or bracket 26 is adapted to be engaged by the recessed surface of the torch member 18. In this manner the flanged sleeve 26 will be depressed upon the support I! when the torch member is inserted into the frame l2. This downward movement of the sleeve 26 in turn causes the pawl 22 to ride over the cams 2|.
The energy-storing mechanism comprises ahelical expansion spring 28 inserted between the flanged sleeve 26 and the adjusting nut 29, which latter screw-threadedly engages the support l1. By means of the nut 29, the tension of the spring 28 can be regulated. It will thus be understood that the bracket 26 is depressed into the frame by the inserting movement of the torch member H] against the spring 28.
The knurled thumb-screw 30 and the spring 5 in the hollow support I! serve to hold the pyrophori-c element It in engagement with the spark-producing wheel I9.
The latching lever or trigger mechanism 32 is pivoted to the pin 33 on the frame by means of the slot 34. The spring 35 serves to keep the 2. slot in resilient engagement with the pin 33. In this manner the pivotal axis of the trigger may be displaced.
One arm of th trigger abuts against the torch member II] when the latter is inserted into the frame, as shown in Figures 1 and 2. The other arm is provided with acam or nose 36 adapted to co-act with the flange or bracket 26 to lock the spring in compressed condition. The spring 35 is so arranged that it keeps the cammed arm of the trigger in resilient engagement with the flange 26.
The bracket engaging surfaces of the cam taper toward a point. In this manner the spring-actuated flange or bracket 26 will exert an upward-outward force on thecammed arm.
This force is held in restraint by the opposing combined forces of the spring 35 and the torch member 10 when the latter is inserted'into the frame, and when the energy-storing mechanism is 'located'in position as shown in Figure 2; As soon as the torch-engaging arm of the trigger has reached the recessed portion of the torch member upon the withdrawal of the latter from the frame, the opposition to the force of the spring 28 is partially removed and the force of the latter being greater than the force exerted by the spring 35, the cammed arm of the trigger will be pushed aside. The released energy stored in the spring 28 thus becomes effective to actuate thecrank member 23 and the sparkproducing wheel I9.
In the embodiment shown in the drawing, the lighter according to the invention is incorporated in an ash-tray or similar article having a central, hollow, raised portion 31 into which the lighter frame I2 is ffitted. The lighter frame may beprovided with a covering plate 38 of suitable design. The lighter mechanism is held rangement the efficiency of the lighter is increased.
When .the lighter mechanism is to be actuated, the handle H of the torch member I!) is grasped manually and moved upwardly. During such upward movement, the parts remain in the position as shown in Figures 1 and 2 until the recessed surface forming the portion 44 passes the trigger arm. The spring 28 will then push the cammed arm of the trigger outward and become released to actuate the crank member 23 and the spark-producing wheel I 9 with a snapping action. As a result,a step of rotative movement is imparted to the' wheel IS, the latter co-acting with the pyrophoric element It to produce a shower of sparks which passes along a path extending toward the nipple l4 and the wick protruding therethrough. The swinging motion of the trigger, however, is only momentary and as soonasthe flanged portion 26 has passed the cam 36, the spring 35 will return it to its normal position, as shown in dotted lines in Figure 3.
In this connection it will 'be'noted that the pyrophoric element is slightlyoff centerv of the spark-producing wheel Hi. In this manner" the shower of sparks will ave an upward direction.
The timing is such that the shower of sparks will be produced just as the exposed wick is about abreast with the pyrophoric element I5. As a result the fuel-charged wick is ignited to produce a flame which may be utilized for any desired purpose as, for instance, lighting cigars, cigarettes, pipes, candles, or the like, and in so doing the torch member may be passed from hand to hand as desired.
When the torch member ID has served its intended purpose, it may be returned into the frame I2 as shown in Figure 1. In so doing, the exposed wick and the recessed portion l4 en gage the snufiing box which extinguishes the flame. After engagement has been effected between the flanged bracket 26 and the recessed surface of the torch member I0, continued downward movement of the torch member will press downward the flanged bracket 26 to compress the spring 28. By reason of the slotted pivot arrangement and the provision of the spring 35, the cammed arm of the trigger will give way to the flange 26 until it engages the lower surface of the cam 36. In this position the bracket and the spring will become locked against recoil, as shown in Figure 2.
In the modification shown in Figure '7, the snufiing box I50. is made part of the flanged bracket 26a. In this manner, the flame will be snuffed out as soon as the torch member engages the bracket 26a.
A lighting mechanism of the character herein described is reliable and eflicient in operation. The simple act of inserting the torch member in the frame stores energy in the spring from which the power is to be obtained for the subsequent automatic operation. Withdrawal of the torch member a predetermined distance from its normal position caused the power-supplying means to trip the trigger mechanism and the energy thus released will cause the production of sparks which ignite the fuel-charged wick.
Although the invention has been described with respect to certain particularly preferred 5- examples, which give satisfactory results, it will be understood by those skilled in the art, after understanding the invention, that various changesandrmodifications may be made without departing from the spirit and scope of the invention, and it is intended, therefore, in the appended claims to cover all such changes'and modifications.
