To all whom it may concern: 1

Be it known that I, SAMUEL E. GUINN, a citizen of the United States, residing at Johnson City, in the county of WVashington and State of Tennessee, have invented certain new and useful Improvements in Gaslight ers, of which the following is a specification. This invention relates to an improvement in gas lighters of that type designed to be connected to the gas supply pipe for gas ranges or the like, and to ignite gas passing thru the lighter at will thru the use of the usual pyrophoric material, the igniter being adapted to be held in the hand and moved to any position for the ignition of a burner or the like on the range.

The use of a lighter of thistype has been heretofore proposed and the present invention is directed particularly to materially simplifying the construction of such types of gas lighters and to providing details of structure which in addition to their simplicity provide a construction capable of withstanding hard usage while at the same time insuring the effective operation under all conditions.

. The invention is illustrated in the accompanying drawings, in which:

Fig. 1 is a perspective view of the im proved gas lighter.

Fig. 2 is a perspective view of the holder for the pyrophoric material.

Fig. 3 is a sectional view illustrating the means for securing the abrader for the pyrophoric material in place.

Fig. 4 is a section 011 line 4-4 of Fig. 3.

The improved gas lighter comprises a flexible tube 1, having a valve structure 2 at one end whereby the lighter may be connected to the gas supply pipe of a gas stove or range, the valve structure herein shown being more particularly described later. The opposite end of the flexible tube 1 is connected with a rigid pipe-like extension 3,

on which is. arranged a handle 4 for convenient manipulation of the device. The free end of the pipe 3 is provided with a rectangular casing, forming an ignition chamber, this casing being open at the end remote from the pipe 3. The end of the pipe 3 at the juncture with the ignition chamber is closed by a disc of fire resisting material 5, formed with a fine opening therethru as 6, whereby the gas is delivered lengthwise the ignition chamber in a, comparatively fine stream. The abrader 7 is held within the lgnition chamber and against one wall thereof in. a manner permitting its convenlent withdrawal when desired. To this end, the opposing walls of the chamber are formed with elongated slots 8 of a size to recelve the abrader 7, such as a file or the like, and one longitudinal edge of the abrader is formed with arece'ss 9. screw 10 is threaded thru the wall of the casing to seat in said recess, so that the abrader is held against one wall of the easlng in a manner to permit. its convenient removal, as by withdrawal of the screw 10, the abrader is free to be removed. The wall of the casing of the ignition chamber opposite the abrader is cut away or slotted at 11, the cutaway portion extending into the top and bottom walls as shown. There is thus provided a recess to permit the operation of the holder for the pyrophoric ma terlal. This holder comprises a member formed of intersecting rod- like sections 12 and 13, the former constituting the holder.

proper for the pyrophoric material and be ing hollow thruout its entire length. That end of thematerial holder proper remote from the abrader has its wall diametrically slotted as at 14, the slot extending thruout the full portion of the holder beyond the rod section 13. The rod section 13 constitutes the means for connecting the holder to the spring element and manually operable element whereby the necessary action for the pyrophoric material is obtained. The spring acting element for the holder includes a spring strip, preferably spring wire 15, secured at one end to the casing forming the ignition chamber, then extended longitudinally of the pipe 3 to a position adjacent the forward end of the handle 4, then coiled about the pipe and projected forwardly, with'the terminal secured in the free end of the rod-like section 13 of the holder. This arrangement tends to maintain the holder with the holder section proper 12, resting against the bottom of the ignition chamber. Any tendency to move the holder longitudinallyof the face ofthe abrader tensions the spring member to cause'the holder to return to its normal position. a The manual operating member for the holder comprises a lever-like element 16 pivotally supported at 17 on a screw threaded into an appropriate part of the ignition A set I chamber, the rear end of this lever terminating adjacent the handle in a thumb piece 18. This lever in advance or its pivot as at 19 is turned laterally and its more or less loosely in an opening in the upper end ot the vertical rod-like member 13 of the holder.

The pyrophoric material 20 is placed lcose ly in the arm 12 of the holder proper and is automatically ted to proper position for action in conjunction with the abrader by a spring coiled about the spring wire 15 adjacent the connection of the latter by the holder proper, one terminal of this spring passing loosely thru the adjacent wall of r the ignition chamber and the other terminal resting in the slot 1% formed in the holder proper. The latter spring terminal bears upon the pyrophoric material and maintains the same in proper position to be acted upon by the abrader, the spring automatically feeding the material as it is worn away.

The valve structure 2 comprises a section connected to the tube 1 and a second section 21 threaded thereon to permit comparatively free turning between limits of the lighter relative to the section 21 without interfering with the gas connection. Section 21 is formed for connection with the gas supply pipe and has a cut on 22 therein. A needle valve 23 controls the normal passage of the gas thru the valve section at will.

Obviously with the gas cut off open, gas will flow in a fine stream into and thru the ignition chamber. The holder is now actuated by the use of the hand operating lever and released and the spring will draw the pyrophoric material rapidly over the abrading surface to produce a spark which will ignite the stream of gas passing thru the chamber and thereby furnish a flame which projects a considerable distance beyond the open end of the chamber, and which may of course be used for igniting the usual burners of the range or for other purposes.

Attention is particularly called to the fact that the various parts of the structure are readily separable. The abrader can be readily removed when replacement or repair is desired, the pyrophoric material is almost as conveniently removed, being readily withdrawn from the ignition chamber upon the separation of the manually operable lever; and furthermore the pyrophoric material in said holder is automatically fed to operative position with respect to the abrader, without necessitating manual adjustment of any part.
