SOLDERING IMPLEMENT.
Application filed March 25, 1926. Serial No 97,194.
` This inven'tion relates to the Construction of electrically heated soldering implements.
The object of the invention ,is to so design, construct and Correlate the parts that a rugged implement is provided, the Copper point ot' which is quickly and etlioently heated by a heating element that, although tragile, is tully protected against camage and is arranged in a position where it may be easily renewed it' it burns out.
This Object is attained by providing the end of the tubular shanlr through which the circuit wires are run, with a hollow exteriorly threaded head into which aflanged and slotted end ot a metallic core, that is wound with resistance wire, is detachably fastened, and upon which the end of a sleeve that carries the copper point is screwed. The other end of the heating element 'core extends into the point where it is supported but is free to move longitudinally as the core expands and contracts under temperature changes. The circuit wires are threadcd through the tubular shank and led through the slotted end of the metallic core and connect-ed with' the resistance wire g coiled upon but insulated from the core, after which the sleeve with the point is attached to the head so as to protect the removable heating unit.
In the accompanying drawings Fig. 1 shows a section of the assembled heating unit and the protecting sleeve and point, with the point detachably Secured to the sleeve. Fig. 2 is a similar section with the point integral with the protecting sleeve. Fg. 3 is a transverse section on the plane indicated by the dotted line 3-3 on Fig. 2.
The shank 1 of the implement is a length of metallic tube. Securely fastened on the end of the shank is a head 2 with a socket 3. The metallic core 4 of the heating element has a flange 40 atone end and a flange 41 atthe other end. The fiange 40 of the core is fitted in the soclet in the head and retained by screws 5. A slot 6 is made across the flanged end of the metallic core that is set in the head. The resistance wire 7, suitably insulated, is coiled about the metallic core, in one or two layers, and the ends of the circuit wires 8 that are threaded through the tubular shank are led, one each side, through the slot in the embedded end of the core and are connected with the ends of the resistance wire that is coiled upon the core.
A inetallic sleeve 9 is threaded upon the head so as to protect the heating unit and provide a suitable mass of heat conducting metal. The Copper point 10 may be attached to this sleeve by threading its end and screwing it into the threaded end of the sleeve, as illustrated in Fig. 1, or the sleeve and point may be made integral, as illustrated in Fig. 9. If the point is detachable it may be removed when worn out or injured and another substituted, or a point of a dilt'erent size may be applied. v
The point is socketed and the fiange 41 at the ree end of the core lies within this socket and is supported bythe wall thereot so it retains the heating element in position but is free to move longitudinally as it changes length under expansion and contraction.
lVith the Construction illustrated the heatingunit is located close to the 'Operating end ot' the iinpleuent and this heating unit is easily applied when the parts are originally assembled or readily removed and another substituted in case it should burn out. It is convenient to lead the wires from the core through the slots to the tubular shank. The heating unit is thoroughly protected by the sleeve and point. By making the core :for the heating unit of metal a rigid structure is produced and one in which the core contributes or assists in absorbing heat from the resistance wireand conducting it to the sleeve and point. Thus the implement heats quickly and with a minimum expenditure of energy.
The invention claimed is 1. The combination in an electrical soldering implement having a tubular shank with a sooketed head, a sleeve attached to the head and a point attaehed to the sleeve, of a solid metallic heating element core having an integral fiange at each end with a resistance wire wound about said core between the flanges, one of said fianges being entered into the soclret of and attached to said head, and the other of said flanges extending into contact with but free to niove within the point for supporting that end of the core and transmitting heat to the point without interfering with the lengthwise expansion or contraction of the core.
2. The combination in an electrical soldering implement having a tubular shank with a socketed head, a sleeve attached to the head and a point attached to the sleeve, of a heating element core having an integral flange at each end With a resstance Wine Wound about said core between the fiang'es,
one of said fiange s being slotted to the .edge
of the core andset intoand fastened to the socket 'of said head, and the other of said ifianges extending into contact With but free to move within the point .for supporting that endof the core and transmitting heat to the point Without nte'te'ing With the lengthwise expansion-or cont'action of the core.
3. The combination in an electrical soldering implenent havinga tubular shank With a socketed head, a' sleeve attached to the.
. head and a point attached to the sleeve, of a.
solid metallc heating element core having a flange at each end With a' 'esistance Wire Wound about said core between the flanges one of said fianges being slotted to the edge of the core and fitted into the socket of said head, and the other ofsaid fianges exteuding into` contact With but free to inove within the point to t-ransmt heat thereto, and screws extending through the head and threaded into the slotted end oi' the core.
4. The combination in an electrical soldering implement having a tubulai* shank With a socketed head, a sleeve attached to the head and a point attached to the sleeve, of a solid metallic heating element core having a flange at each end With a resistance Wire Wound about said core between the fianges, one of said flanges being slotted to the edge of the core and set into the socket of said head,` and the .other of said flanges extending into and freely supported within the point, and :screws extending through the head and threaded'into the slotted end of the core, said screws being concealed by the end of said sleeve thatconnect the head and the point. I e
5. The combination in an electrical soldering implement having tubular shank With a headQand'a pointconnected With the head,
- of@ solid n etallic heating element core having an integral fiange at each end With a re'sstance wre `avound about said core between the fianges, one ot' said fianges beng slotted and the slotted end fitted into `and detachably secured to said head, and .the
other of said fianges extending into .contact With and freely supported by the point.
