This invention relates to new and useful improvements in electrode holders for spot welding, soldering or other devices for causing union.

The primary object of the present invention relates to a novel form of electrode holder permitting adjustment thereto whereby connections may be soldered in close fitting and out of the way positions.

With the above and other objects in view,

the invention further consists of the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompan ing drawing and pointed out in the appen ed claims.

In the drawing Figure 1 is a longitudinal sectional View taken through our improved type of torch.

Figures 2, 3 and 4 are horizontal sectional views taken on lines 22, 33 and 44 respectively through Figure 1 of the drawing. Referring to the drawing in detail wherein like characters of reference denote corre- 25 sponding parts, the reference character 10 indicates generally a tubular handle memher having the end walls 11 and 12 therefor centrally apertured, as at 13 and 14 respectively. The interior of the housing is filled 30 with a suitable fireproof and heat resisting material which in this instance is of composite formation in the nature of one part plaster and two parts asbestos.

An attaching plug or tube, such as indi- 35 :zated at 15, and preferably formed of brass or other conducting material, is extended through the opening 14 in the end wall 12 of the handle member 10 and an appreciable distance within the packing carried thereby.

to A conducting tube 16 is attached with the opposite end of the handle member 10 after the manner of the plu 15. The innermost projecting portion of t e attaching tube 16 is provided with an attaching socket 17 into which the adjacent end of the plug 'or tube is received to establish a conducting connection therebetween.

Disk members 18 and 19 respectivel centrally apertured and slidably mount upon m'ihe outer side walls of those portions of the plug 15 and tube16 within the handle member 10, dispose the-outer surfaces thereof for contacting engagement with the adjacent inner'sides of the end walls 11 and 12 of the r handle. The outermost end of the conducting tube 16 is flattened and apertured to provide anattaching ear20 for registration with a complemental ear 21, carried by an attaching socket 22, to facilitate accommodation of a common fastening element 23 therethrough whereby a pivot mounting is established therebetween.

An electrode 24having one end extended withinthe bore ofthe attaching socket 22 is pneferablyformed of carbon and projected outwardly anappreciable distance therefrom. Theoutermost projecting end of the attaching plug or tube 15 has an annular depression orgroove25 within which the looped extremi- 7O ties 26 of afastening grip 27 are sprung. Said grip is carriedby a cable 28 having connection atits opposite end with a source of. current 29. A conducting wire 30 joined atone end with the remaining pole or contact of the sourceof current 29 carries a biting grip 31 at its opposite end. The source of current29 mayxbe. either 1 a low voltage battery, namely six volts, or the-corresponding taps or binding posts of a step down transformer. so

Theinterior of the conducting tube 16 may be filled with dry asbestos filler.

IFrom the-illustration of our invention in Figure 1 of the drawing, the method of the spot welding or solder is shown: the adjacent endsofwires are shown overlapped, the SOlLdBI','WhBthBI rosin or acidcore is interposed between the lap connection of the work and theadj aeent end of the electrode 24. The lowvoltage current assingthroughthe torch will heat solder su ciently to cause same to run and adhere to the overlapping ends of the wires but the heat will not be sufficient 91 intense enough to. cause the solder to run off or fry and spit as generally occurswith 95 he d i o sa Y The biting clip '31, carried bythe'lead wire 30, is then grippinglyengaged with one of the overlappingends of the wires. The'latter connection completes the circuit and contacting engagement of the electrode 24 with the the attaching ear to facilitate angular adjustsolder will instantly join the aforementioned ment to the electrode therefor. over apping free ends of the wires. It is to In testimony whereof we afiix our signabe noted that no current is used when the tU S- electrode is disengaged from the solder or the clip 31 released from the work whereby the amount of voltage required for making the ordinary spotsolder connection is equivalent to that of the flashing of the headlights of a motor vehicle; the above comparison being drawn inasmuch as the improved torch may be ell'ectively connected with the storage battery of a motor vehicle.

As a further safeguard against burning of the hands when employing the improved torch in close places, we provide a protecting sleeve 32 tGlGSCOPlC-Zlllf associated with the conducting tube 16 as shown in Figures 1 and 3 of the drawing. The pivot connection 23 between the adjacent ends of the conducting tube 16 and the socket member 22 for the electrode 2% will permit of angular disposition of the latter to make or establish connections at any place or from any angle.

The invention is susceptible of various changes in its form, proportions and minor details of construction, and the right is herein reserved to make such chan es as properly fall within the scope of the appended claims.

Having thus described the invention, what is claimed is l. A soldering torch comprising a tubular handle member having an insulation core, an attaching plug extended axially within one end and core of the handle member, a conducting tube extended in like manner within the opposite end of the core and handle having an attaching socket receiving the adjacent end of the attaching plu an attaching ear formed upon the outermost projecting end ofthe conducting tube and an electrode holding socket having a complemental ear receiving a pivot pin therethrough common with the attaching ear, and the projecting extremity of the attaching plug having an annular clip engaging depression.

2. A soldering torch comprising a tubular handle member having the end walls therefor centrally apertured, an attaching plug extended through the aperture in one end wall of the handle a conducting tube extended in like manner to the attaching plug through the opposite end wall of the housing having a socket receiving the adjacent end of the plug, disk members carried upon those portions of the plug and tube within the handle and engageable with the adjacent surfaces of the end walls therefor to space the plug and tube from the edges of the central apertures, an attaching ear formed upon the outermost projecting end of the conducting tube, and an electrode carrying socket having a complement-a1 ear lying flush with and movable upon GEORGE E.
