ment in Torches, of which Ythe followingrfis 'f ThisV f invention f `relates to blow-torches, especially that typelof blow-torch in which a pump is used toicompressfair in the reservoir that contains the fuelf Torches of this character are not broadly new but we Ybelieve that" lw'e *have *f' designed" an* inprove'-V ment in the construction of the torchs' Yas to furnish a very much-better support for the burner and so as to avoid a very greatfault and annoyance in connection with i11- struments of this character. It is found that the filled joint between the nut on the burner stem and the reservoir top, which is usually a soldered joint, frequently breaks and requires repair, for obviously no Inat-V ter how small the break it impairs the operation of the instrument by allowing the compressed air to escape.

It is the object of our Vinvention to avoid this breakage of this joint. This we do in the simple way hereinafter described.

In the drawings,- Y

Fig. 3 is an enlarged detail of the joint between the stem of the torch and the reservon'.

The reservoir is designated a and is provided with a suitable base b and a coiled wire handle C. The usual pump d that passes through thetop of the reservoir operates in the usual way. e represents a priming pan. f is the perforated sleeve lor barrel that forms the mixing chamber, z, and z' are soldering iron supports and y' is the valve stem. The barrel, valve, that depends from the barrel, constitute the burner. Y

The opposite-"endof-the bridge lits inbetween `the nut m, which secures the handle y in 'plafand theL top. Between the Atatami ithesi'de wall is a reinforcing plate a. The

nut, plate, bridge end and walls of the reservoirv are all soldered together, forming a secure anchor for this end of the bridge.

Interveningl between the beam portion and the lip n is an enlargement which has a Patented Aug. p13, 1:91.81.

s jointand tomore stably threaded hole through it through which the stem of the burner'screws. v

The lip n of this bridge or reinforcing member 1s soldered to the side of the can or reservoir and the stem of the burner threaded through the bridge. The beamk ofthe bridge is soldered to the topl of theY reservoir. The stem of the burner passing through the bridge secures the location of the nut lo just above the bridge and consequently vthe top of the can is pinched in between the nut Y and the bridge and there can be noi-relative movement between these two members so as t0 tend to break the soldered joint.

A very important condition that results from this bridge arrangement is that vthe 'warping action of the top isY substantially prevented by reason of the long lip n which runs down and abuts against the side of the can or reservoir at. This causes the tubular side wall to resist any warping tendency of the top for obviously with` the lip abutting along they inside of the side wall and soldered thereto, any warping tendency of the top as a whole is resistedV by the strong tubular side wall. It is well known that there is very little warping tendency in a tubular construction, no matter how thin.

From the above description it is apparent that not only is a stronger reservoir construction secured but by reinforcing the top with a bridge having a long anchorage to the side wall, any warping strains are trans ferred to and resisted by the tubular side wall. Hence the filled or soldered joint between the nut and the top of the reservoir is protected from the tearing stresses due to warping and it is also in-Yconnection with the adjacent portion of the top pinched to the reinforcing member' itself so that relative movement and disruption of the joint is almost impossible. Iirthermore, the burner is supported instable upright position with respect to the reservoir.

What we claim is: e

1. In a torch 'for the purpose specified, the combination of a tubular reservoir, a

lstem passing through the top of the reservoir and having a joint with the top of `the reservoir in which isy included a filled connection, and a reinforcing bridge having a beam portion adapted to lie underrthe top and a lip portion adapted to extend along the `tubular side wall of the reservoir, for the purpose specified.
