UNITED STATES PATENT OFFICE.
GILMAN PETERSON, OF ORFORDVILLE, WISCONSIN, AND EUGENE Mi BOURNONVILLE,
OF JERSEY CITY, NEW JERSEY, ASSIGNORS TODAVIS-BOURNONV ILLE .ACETYLENE.
DEVELOPMENT COMPANY, OF JERSEY CITY, NEW JERSEY, A CORPORATION OF SOUTH DAKOTA.
Specification of Letters Patent.
GASEOUS-FUEL-BURNING WELDING-TORCH.
State of New Jersey, have invented certain new and useful Improvements in Gaseous- Fuel Burning Welding-Torches, of which the'following is a specification.
This invention relates to blowpipes or torches and blowpipe or torch burners such as illustrated, for example in Patent Number 880,099, to Rodrigues-Ely and Gauthier,
dated Feb. 25, 1908. Such blowpipes or torches use gases under greater or less pressure, for example acetylene and oxygen, for producing a flame of great heat intensity, suitable for welding and other purposes requiring great, localized heat. In the ordinary use of such torches the expansion-of the gases at the burner mouth is sufficient to maintain the burner at a low enough temperature to avoid injury; but when the welding operation requires the burner to be advanced into a hole or recess in the metal, the flame streaming backward from the hole over the burner tends to heat the latter to such an extent that the acetylene flashes back in the torch, and, of course, the great heat is bad forthe burner structure itself. It is the object of this invention to protect and cool the burner under such circum stances in a simple and eiflcient manner.
.The invention may be said to comprise a shield mounted on the burner adjacent the end thereof and means for directing a current of gas for cooling against the rear of the shield so that the shield serves both to deflect the backward-streaming flame away from the burner and to reflect the flow of cooling gas back along the same, and the cooling gas impinging against the shield,
serves to reduce the temperature both of the shield and of the extreme tip of the burner. Viewed in another light, the invention comprises means for directing a current of 1 burner..
An important feature of the invention is the disposition of the conduit, for delivering the cooling gas against the shield annularly about the burner, as by means of a sleeve spaced therefrom, so that the burner is surrounded in efiect by a' gaseous envelop, which is reflected backward over the burner.
Other phases and details of the invention will be found set forth in the claims.
In the accompanying drawings illustrating one of the possible embodiments and applications of the invention, Figure 1 is an elevation of an oxy-acetylene torch embodying the principle of our invention, and Fig. 2 1s a longitudinal section through the head,
and burner portion of the torch.
It is immaterial, of course, what is the particular form of the torch to which the invention is applied. The numeral 1 indicates a form of oxy-acetylenetorch now in commercial use, of which the numeral 2 may designate the burner as a whole. The oxygen enters the torch past the cock 3, traverses the pipe 4, and flows through the central passage 5 of the injector 6 in the burner,
to and through the burner tip 7. The
acetylene enters the torch past the cock 8, traverses the pipe 9, and is entrained through the lateral passages 10 of the injector by the oxygen.
This illustration and description is merely for the purpose of showing the invention in connection with an operative torch of this general character; and it is to be understood that the novel constructions and arrangements now to be pointed out depend in no Way upon the special features of torch construction proper just outlined.
The numeral 11 indicates the shield mounted on the burner toward the end thereof. Preferably, the shield is cupped, with its concave side rearward. If desired, the shield may be mounted removably on. the burner, which may be effected by forming the shield integral with the extreme end of Patented 0a. 5, 1909.
the burner which may itself be unscrewed.
Gas for coolmg, preferably air under pressure, is admitted within the sleeve 12, toward the rear thereof, by any suitable means, as a pipe 15. The flow of air may be controlled by any suitable device, for example a valve 16. The pipe 15 may be supplied from a tank of compressed air or from any other source of gas under pressure.
What We claim as new 1s:1
1. A blowpipe or torch of the character described havin a shield adjacent its burner end and means tor directing a current of gas for cooling against the rear of said shield.
2. A blowpipe or torch burner of the character. described having a shield adjacent its end and means for directing a current of gas for cooling longitudinally of the exterior of theburner against the rear of the shield.
3. A blowpipe or torch of the character described having a cupped shield adjacent its burner end and means for directing a current of gas for cooling against the rear of said shield.
4. A blowpipe or torch burner of the character described having a cupped shield adjacent its end and means for directing a current of gas for cooling longitudinally of the exterior of the burner against the rear of the shield.
5. A blowpipe or torch burner of the character described having means for directing av current of gas for cooling longitudinally of the exterior of theburner and a deflector adjacent its end against which the gas impinges and is reflected backward over the burner.
6. A blowpipe or torch burner of the character described having a shield adjacent its for admitting gas under pressure for cooling to the rear ofsaid chamber.
8.. A blowpipe or torch burner of the character described having a shield adjacentits end, an external annular shoulder in rear of said shield, a sleeve seated at its rear end upon said shoulder and afi'ording between the sleeve and the burner an annular gas conduit open toward the shield, and means for admitting gas for cooling under pressure to said conduit.
9. A blowpipe or torch burner of the characterdescribed having a shield mounted removably thereon adjacent its end and means for directing a current of gas for cooling against the rear of the shield. 10. A blowpi e or torch burner of the character descri d having a removable and adjustable sleeve mounted thereon but spaced therefrom so as to aflord .an annular gas conduit, means for admitting gas under pressure to saidconduit, and a shield mounted on the burner toward the end thereof to be impinged bythe gas.
