This invention relates to soldering-irons and more particularly to electric soldering-irons and stands therefor.

The invention together with its objects and advantages will be best understood from a study of the following description taken in connection with the accompanying drawings wherein Figure l is a side elevational View of an imin proved soldering-iron and stand therefor.

Figure 2 is an elevational View of the soldering-iron.

Figure 3 is a top plan View of the stand.

Figure 4 is a longitudinal sectional View taken i5 substantially on the line 4 -4 of Figure 3 and looking in the direction of the arrows.

Figure 5 is a top plan view of a second form of stand, and

Figure 6 is a sectional View taken substantially g., on the line 6 5 oi Figure 5.

Referring to the drawings by reference numerals it will be seen that the improved soldering-iron is indicated generally by the reference numeral 5. The soldering-iron 5 comprises a point 6 of any suitable material provided on one end of a tubular shank I which at its opposite end is equipped with a suitable handle Suitably arranged in the shank portion I of the iron is a heating coil 9 which is connected by Wires I to contact prongs II suitably provided at the free end of the handle 8.

In Figures l, 3 and 4 is shown one form of stand I2 for the iron 5.

In this form of the invention stand I2 comprises a hollow shell-like body or box I3 in the top of which is suitably mounted an electrical outlet I4 secured in position as indicated generally at I5.

Also mounted in the top of the stand I2 is hi0 a lamp casing I6 provided at its upper end with a lens II. In the lower end of the casing I6 is a lamp socket I 8 to accommodate the electric lamp bulb I9. The outlet plug I 4 and lamp socket I8 are suitably wired together and to an 45 electric cord 2G, one end of which will be provided with a plug (not shown) for placing the outlet I4 and the lamp socket I8 in any suitable electric circuit. Embodied in the lamp socket I 8 is a suitable toggle switch the toggle lever 50 of which is accessible from one side of the stand and is indicated by the reference numeral 2I. It will thus be seen that the lamp I9 will act as a tell-tale lamp for indicating whether or not the switch is on.

When it is desired to heat the iron 'I the latter is placed on the stand as shown in Figure 1 with the contact prongs II engaged with the electrical outlet I4 in a manner apparent. The switch 2I is then tripped for completing the circuit through the lamp I9 and the coil 9 of the iron for heating the latter. Thus it will be seen that as long as the switch 2I is on the lamp I9 will be illuminated for indicating the fact that the switch 2| is turned on. When the switch ZI is in open position the lamp I9 will remain dark. Thus the possibility of the flow of current through the coil of the iron when the latter is on the stand and not intended for use, as would result in the burning out of the coil of the iron is eliminated by reason of the fact that through the medium of the lamp I9 the operator may readily ascertain whether the switch 2| is in an on or oil position.

In Figures 5 and 6 is shown a second form of stand the same in these figures being indicated by the reference numeral 22. In this form of the invention there is suitably mounted in the top of the stand an electrical outlet plug 23 to which is electrically connected the wires of an electric cord 24. The receptacle 23 is adapted to receive the prongs II of the iron 5 and when the prongs II of the iron are so engaged With the receptacle 23 the circuit through the coil 9 will be completed for heating the iron.

Also in this form of the invention there is mounted on the top of the stand 22 a holder 25 for the iron, the holder 25 simulating in appearance the outlet plug 23, and constituting in effect a false outlet plug adapted to receive the prongs II of the iron 5 for supporting the iron on the stand 22 when the iron is not to be used. Thus it will be seen that when the iron 5 is in one position on the stand 22, that is to say with the prongs II engaged in the electric outlet plug 23, the tool will be in circuit while when the tool is in a second position on the stand 22, that is to say with the prongs II engaged in the outlet simulating plug 25, the tool will be out of circuit.

It is thought that a clear understanding of the construction, utility and advantages of an invention of this character will be had without a more detailed description.

Having thus described the invention what is claimed as new isz- In combination, a soldering tool having at one end a soldering point and at a relatively opposite end a handle, and also having a heating coil connected at one end to said point and at a relatively opposite end to a pair of spaced apart insulated contactprongs extending from the free end of said handle, and a box-like supporting stand for said tool having an electrical outlet plug mounted flush with the top Wall of the stand for receiving the contact prongs in a manner to support the tool vertically on the stand, said plug having means for connection with a source of electric current to complete an electric circuit through the heating coil of the tool, and an electrically operable telltale signal mounted on the top Wall of the said stand and in proximity to the said plug and Wired in circuit with said outlet plug, said electrically operable tell-tale signal embodying an electric switch exposed through a side Wall of the stand to be operated for controlling the circuit through the signal and the coil of the tool.
