ISOLDERING IRON.
Application filed June 14, 1923. Serial No. 645,241.-
To all whom it may concern.
Be it known that I, WVILLIs A. Burns, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain newand useful Improvements inSoldering Irons, of which the following is aspecification. j
his invention relates to improvementsin electrically heated soldering irons .and has or its principal object to produce an improved device of the class described which is simple and economical in construction and operation. I
More specifically my plates the manufacture of a device of the class described by the process of forming, in combination with an electrical heating element,'a sheet metal blank, to produce a finished article much cheaper than electric devices heretofore have been produced for similar purposes.
The invention may best be understood by reference to the accompanying drawings illustrating one form in which it may be embodied.
In these drawings:
Figure 1 is a plan view of a soldering iron constructed in accordance with my invention.
Figure 2 is a sectional view taken on line 22 of Figure 1.
Figure 3 is a View of a sheet metal blank from which the main portion of the device is formed.
Figure 4 is a view of the blank in partially formed condition with portions broken away and showing a portion of the heating element in dotted lines.
Figure 5 is an enlarged end of the iron before the eration.
Figure 6 is a view similar to Figure 5 but after the final pressing operation.
The main elements of my improved soldering iron comprise a head 10, a shank 11 and a handle 12. The electric heating device comprises a resistance element 13 which may be of any ordinary form including coils of resistance wire insulated by suitable means such as mica sheets. The resistance element is preferably formed in a relatively flat secthe head 10 as it is finally formed, as will now be described.
The head 10 and shank 11 are preferably formed of one piece of sheet metal. For this purpose a blank A is shaped substantialinvention contemdetail view of the final pressing op- .15 is provided Figure 3, in which a portion to form the head 10, and the portion 16 is provided to form the shank 11. By forming operations of the usual kind, preferably by machinery, the side margins 17, 17, of portion 15 are turned upwardly and the side margins 18, 18 of portion 16 are also turned upwardly, substantially as shown in Figure a. The central part of portion 16 may also be conca-ved to extend a short distance into the flat central part of port-ion 15 to form a shoulder, as shown. With the parts in this form, the resistance element 13 may be fitted in the head,which is of proper dimensions to receive said element between the side margins 17, 17 thereof, but at a distance from the working point 20. The conductors 14, 1 1 of saidresistance element are also'inserted between the walls 18, 18 of shank 16. The walls 17,v 17 are then folded over the resistance element, with their margins meeting substantially on the center line. The walls 18, 18 of the shank are also closed together, preferably in a tubular form, as shown, with the conductors 14, 14, extending therethrough. The folded walls 17, 17 at the extreme point of the head and beyond the heating element 13 are finally pressed against the lower wall, as shown in ly as shown in of substantial thickness, for the application of solder in the usual manner. 12 may be of any suitable form and construction, as for example, it may comprise a hollow piece of heat resisting material convenient in shape, with shank 11 fitted into one end and with conductors 14c, 14 extending therethrough for connection with a source of current in the usual manner.
It will be understood by those skilled in the art that the operations necessary for forming the blank described are readily accomplished by machinery including suitable forming dies, and that the several operations may be performed singly, or more than one operation may be performed simultaneously, by means of compound dies, without departing from my invention. It will be further obvious that the shank 11 might be shaped in hollow form before the heating element 13 is applied, in which case the conductors 14;, 14 would be inserted through the shank.
