In my fulminate-torch, which is the :subject of this invention, Iemploywhatis known as fulminateftapev-that.is,.a `tape of vpapervor other suitable material havingfulminate-pellets on it at givendistances `apart-and,ar-

1 produces a flash of dame which ignites the ELS. g A is the magazine,constructed to receive the fulminate-tape b in .the forinof a coil within it, and closed on its one side bya lid, B. (l is the hammenwhichris here represented as. compesed-oi' a bent flat spring, and is made to forma part of theinclosing-wallsof vthe azine, and attached to the latter, andE the tape-ieeder,..which latter is composed of an .elastic lateral projection-from a plate-cam, G, Within the magazine. This rcam is litted to freely turn abouta stud, c, on which the coil oftape is .placed, and serves Ythe purposenot only of operatingthe tape-feeder E, but also 0n the hammer. The magazine-'frame has combined with it a lkey-turner, J,having cheeks orsides arranged lat suitable distances apart, and serving to receive withinthemth'e handle of ,a gas 4key or tap, in order that the tap may be turned bythe ltorch to let thegas on or off,- which will be Efound very convenient, especially when l. the gas-keyis Situated at a `distance lout of vconvenient reach lby hand. Said key-turner J is here represented as combined lwith the magazine or frame of the latnter by casting it iny o ne piece ywith the frame and with fthe socketa,by which said frame is connected .withthe steml. This construction is not only a simple and cheap .o ne, but it gives ygreat stability and strength, and .causes thekey-turner and magazine to mutually supporteach other.

The devices for operating thetumzblcr or .camG to feed forward the fulminate-tape `b its required distance, and to raise the `hammer C, consist of a yconnecting rod, f, attached to the cam and passing down through the stem I, .where (or lin the handle lof the torch) it is pressed upward-or .outwardby a spring, g, ,when the thumby of l the hand holding the torch is `removed .from a` trigger, JL, -yvhich proj ects laterally from the rod f through .a slot in thestem near the inner en d of the handle. By pulling downl onthetrigger the tape-feeder E is -moved forward, andthe hain- .mer O :raised until the .cam Gfv` clears theI ,slidelip on the latter. The springhammer C. then being liberated, strikes the fulminate-pellet of the tape, advanced by the forward action of the feeder E onto or over the anvil D, and gives the necessary ash to ignite the gas.

Io facilitate the feed of the tape from the magazine onto the anvil and prevent it from being caught by any angular projection likely to impede it, the front of the magazine is constructed or provided with a circular concentric guide, t', which serves to direct the tape in a regular and easy manner to the anvil as the tape leaves the magazine.

To insure the proper insertion of the coil of tape within the magazine so that its free end will not be projected through the opening k. between the hammer and the magazine, but will be projected, as required, through the lower opening in the magazine for the operap tion upon it of the feeder E, the lid B is pivoted at l to the upper forward portion of the magazine-frame--that is, at a point between the hammer C and the feeder E-and when thrown up or opened, as shown by vdotted lines in Fig. 1, is arrested by a stop, K, whereby said lid closes the opening 7c at the receiving side of the magazine, thus acting as a bar to the entry of the free or loose end of each fresh coil of fulminate-tape through said opening, and restricting the introduction of the coil so that its free end will pass through the lower opening in the magazine to the guide i, or surface, against which the feeder E operates. Furthermore, the magazine cover or lid B is constructed at its opening end with a hook, m, which engages with a stud, n, on the frame, and locks said lid when closed. It is also furnished with a thumb-piece,o, to facilitate the opening and closing of it.

The piece K, which projects from the upper side of the anvil. in front of that portion of the latter which receives the blow ofthe hammer, not only forms a stop for the lid B, as described, but also a guide for the spent end of the fulminate-tape to assist in its direction, and likewise serves as a guard to prevent the firing of the exposed end of the tape by the ignited gas.

The anvil D, where it receives the blow ofthe hammer, is made wedge-shaped or sharp, so as to prevent an easy or uninterrupted passage on either side of it for 4the llame produced by the striking of the hammer on the fulminatetapein the direction in which the flame is required to take.

The following are additional peculiarities 0f construction and operation which have not yet been specially pointed out in the foregoing description: The tape-feeder E and the guide i unite with the hammer O to form in part the walls of the magazine A. Again, the lid d of the hammer G, under which the cam G operates to lift the hammer when the trigger h is'depressed, is made inclined, as clearly represented in Figs. 7 and 8, whereby, in the .lifting-operation of the cam, the hammer is retained in position on the latter by the inclination of the overlapping lip; but after the feeder E, which here is shown as an attachment to, or forms part of, the cam, has fed forward the fulminate-tape, and the l hammer has been released and iired the pellet, the lifting portion of the cam in the return stroke of the latter catches on the end of the lid d and pushes the spring-hammer slightly to one side to allow of the cam making its return stroke without lifting the hammer or interfering with the hold of the tape by the hammer against the back action of the feeder E.

This completes the description of the construction of the instrument as regards the adaptability of the latter to burners not provided with a chimney or shade-excluding application of the torch to the burner otherwise than down throughV the chimney or shade, it only being necessary in the manipulation of the instrument first to open the gas-key or tap by means of theA key-turner J, then to bring the anvil I) over the burner, and simultan eously to pull down on the trigger h, so as to feed forward the fulminate-tape and cause the hammer C to explode one of the pellets thereof.

When, however, it is required to apply the torch to an Argand burner or toa burner having a chimney or shade, as above described, then the nose or forward end of the anvil has applied to it (as shown in Figs. 5 and 6) a. tube, M, having a bell, N, attached to its outer end for insertion down within the shade orchimney, and serving to conduct the gas as it issues from the burner to the ilame produced by the striking of the hammer. To thisend the tube M is constructed with a longitudinal To prevent a too free escape of `the i1lum1.

hating-gas through the holes fv as the bell N is brought over the burner, said holes are surrounded by anges or necks w, which have the effect of retarding the ow of gas through them.

The transverse slit s in the nose is advantageous without the tube M, as it provides for the spread of the gas across the flames of the fulminate,. as indicated by arrows in Fig. 1.

I claim- 1. The combination, with theframe of the magazine A, of a key-turner, J, cast in one piece with said frame, essentially as and for the purposes herein set forth.

2. The combination of the stem I, the handle I', the magazine A, the connecting-mdf, the spring g, the trigger h, and the tumbler or cam G, substantially as and for the purposes specified.

3. The magazine lid or cover B, pivoted to the magazine-frame at al point, l, between the hammer C and the tape-feeder E, essentially as described. i

4. The guide, guard, and stop K, in combination with the magazine A and its lid B, substantially as specified.

5. The combination of the circular concentric tape-guide i, with the magazine A, and the tape-feeder E, working outside of the exterior concentric surface of said guide, Whereby the feed of the tape from and outside of the magazine is facilitated, essentially as described.

6. The sharp anvil D, in combination with the hammer C, having a striking action in the the direction in which it is required to pass the ame, substantially as specified.

7. The anvil D, constructed with a transverse slit, s, in its nose, substantially as and for the purpose herein described.

8. The magazine A having its Walls in part formed of the hammer O, the tape-feeder E, and the guide i, essentially as described.

9. The vibrating cam G, in combination with the hammer C and its inclined lip d, substantially as and for the purpose herein described.

10. The combination, of the fulminate-tape feeder E, with the cam G, to which said feeder is attached, substantially as specified.
