. HAND-TORCH.

Specification of Letters Patent. Patented Aug, 21, 1917,

Application filed February 2,1917. Serial No. 146,300.

To all 107L077; tmay concern." 1 y I a it known that LVALnNrrnn MFBEARER, a citizen of the UnitedStates, residing at Ligonierylin the county of ,Westmoreland and State of Pennsylvania, have invented new and useful Improvements in Hand- Torches for Back-Firing in Fighting Forest- Fires, of whichjthe following is a specification. 1 r y r 1 My present invention pertains to gasolene blow torches of the hand type, and has for itsgeneral object to provide a gasolene hand torch in which the elements are so constructed and relatively arranged that the torch is adapted foruse to advantage in the so-called back firing against forestfires;

where there is: inflammable material as Well as inflammable material that is somewhat damp, thereby decreasingthe possibility of the back fire-F 'um in or crossin the fire lene for pre-heating purposes.

lane, as is desirable, and this without subjecting theopcrator to the necessity of fre quently assuming an extreme stooping posture. a l

The invention will be fully understood from the following description and claims when the same are read in connection with the accompanying drawings, in which:

Figure l is a broken elevation of the torch constituting the preferred embodiment of my invention. 1

Fig. 2 is a longitudinal central section, taken through the swivel connection.

Fig. 3 is asection showing the drip cup and appurtenances in plan together with the tiller in said cup. 1 r

Fig. 4 is a detail view showing the position in which the parts are placedwhen it is desired to charge the drip cup with gaso Similar numerals of reference designate corresponding parts in all of the views of the drawings.

Among other elements my novel torch comprises a long and slender tank 1, adapted to serve as a convenient handlein manipulating the torch and to prevent excessive stooping. In the preferred embodiment of my invention the said tank 1 is three feet long by one and three quarters inches in On its side at an intermediate point in its length the tank 1 is equipped with a longi- 1 and then laterally is a pipe 7 on the outer end portion of which is a thread 8. In the said outer end portion of the said pipe 7 is a socket 9, of circular form in cross-section, and ground to fit snugly in said socket is the stem 10 of a pipesection 11 on which is a shoulder 12. The said shoulder 12 is engaged by the flange 13 of a coupling member 14 which is threaded on the pipe 7 and is adjustably fixed thereto by a set screw 15 so as to assure a tight fit of the stem in its socket. The pipe 7 is provided with a chamber as shown and said chamber is occupied by packing 10 By turning the member 14: and crowding the shoulder 12 against the said packing, the packing is caused to make a close fitting joint, and by the same manipulation wear may be taken up. In the manner described the pipe section 11 is connected in a swiveled manner with the pipe 7, and hence said section 11 is free to be turned about its axis. It will also be noted that the swivel connection is such that there is no liability of leakage of gasolene or commingled gasoleneand air even when the mixture is under considerable pressure. For this reason I prefer to employ the swivel connection constructed in the manner described.

On its outer end the pipe section 11 carries a foraminous burner 16 which is provided with a valve 17 and is otherwise in general of the ordinary well-known construction common to blow torches. A rearwardly-extending portion 18 of the burner surrounds the stem of the valve and is exteriorly threaded as indicated by 19 for the engagement of an interiorly threaded collar19. This collar 19' is provided with a lateral arm 20 which is sufiiciently long to permit the drip cup to. be turned about the burner freely, .and on said arm is the drip cup numbered 21; the said drip cup being disposed at an angle of about 35 degrees to the burner as illustrated, The said cup is designed to hold a mass of asbestos or equivalent absorbent ma terial 22, and is providedon the inner sides of its opposite side walls with inwardlyextending prongs 23 which are preferably arranged in staggered relation as illustrated and are designed to rest in the absorbent ma of m novel torch it will be manifest that it is unnecessary for the operator, to frequently assume or remain in an extreme stooping position; also, that the capacity of the torch to burn inverted position con tributes materially-to it efficiency when used for back-firing purposes, and that by reason of the absorbent material or sponge'in the drip cup the burner can be heated while thetorch is being carried and rou hly manipulated. I would also have it understood thatthe burner burning as fuel cominingled gasolene and air is adapted to fire material more rapidly and in a continuous stream.

When the torch is to be lighted, the burner is first turned on the swivel to an elevation of approximately degrees and then the rear end of the torch is slightly elevated. The said elevation of the rear end of the torch or tank thereof, as stated,- leaves the burner elevated about 35 degrees, and when the drip cup is tameduntil it rests under the burner, said cup will be in an appro'Xi inate'ly horizontal. position and can be charged with gaso'lene from the tank.

I would have it understood that without departure from my inve tion or from the scope of my appended claims, the dimensions of the tank may vary from one and one half feet to four feet in length, and from one inch to three inches in diameter;

Having described my invention, what I claim and desire to secure by Letters Pat ent, is:

1. A drip cup for torches and other uses, comprising cup having inwardly extend ingspac'edpr'on'gson opposite walls, the prongs on one wall being arranged with their inner portions in lapped relation to the prongs on the other wall, and absorbent materia'l arranged in said cup and receiving and held by the prongs;

21- A hand torch comprising a combined tank and handle, a burner connected there' with, drip cup also connected with the combined tank and handle and arranged at the opposite side ofthe burner, with reference to the'combined tank and handle, and also arrzunged to receive drippings from the burner and having means for securing absorbent material within its wall, and absorbent material disposed in. said cup 7 and engaged and held by said meanswhereby displacement of the absorbent material in Copies of this patent may lie-obtained for cidental to hand manipulation of the torch is prevented.

3. A hand torch of gasolcne blow-torch type, comprising a long and slender combined tank and handle, a pipe connected with the interior of said combined tank and handle and extending laterally relative to the forward end thereof, and a burner carried on the laterally-extending portion of said pipe and disposed in a plane parallel to that of the combined tank and handle and connected with and arranged to be supplied with gasolene through said pipe;
