To all whom t may concern.'
Be it known that I, HARRYH. I-Lu'nus,
a citizen of the United States of America, residing at Ocontjo, in the county of Oconto and lState .of Wisconsin, have invented certain new. and useful Improvements in Electric: Self-Feeding `Soldering-Irons, of which ,the following is a specificatmn, reference' behad therein tothe accompanying drawly invention relates to improvements 1n electric soldering-Hons, and conslsts 1n the combinatlons, constructwns, and arrangements herein described and claimed.

provide a novel meansA or permitting or :stopping the fiow of melted solder,land a means for readily adjusting theow to suit ,the classl of work being done." f
A` still further objectfof vjmyl invention: vis to provide aIsoldering-iron.whereby the elecltrical .heating element maybe dispensed with, s0 that the soldering-iron ma be" heat-4v edin the usual way by a .tinners last fur- .1 nace, when so desired. c
With .these and othery objects in viewv this invention consists fof certain novel combinations, constructions and arrangements of parts as will be hereinafter fully described and claimed.

Fig. 3 isa sectional plan viewy ofthe s'oldering-iron takenk on vline 3-34 of Fig. 2.

Fig.l 6 is a perspective view of 'a ferrule or tube which is adapted to take theplace of the electrical heating element, when the iron is to be heated in a furnace.4 Fig. 7 is -a' side elevation, partially in section of the' electri- 1 designates ly formed-of copper` and which may be ofthe pyramidall form 1n common use, or o'fhatchet st le generally used for running seams.

The upper end of the tip 1 is internally threaded and is adapted to receive a screw 3, having a passage 4 which is in alinement with the passage 2 in .the tipmernber 1. Th1s passage 4 runs centrally ofthe screw is at right angle with the 'passageff Avalve pin 6, having a somewhat ypointed vend, 7

.electrical heating coil .22-A contained within the casing 23,- is[composed"ofl alternate layers of resistance. wires land' inter losed insulatin material, preferably mica. his casing 23 as an inner 'longitudinally extended central tubular portionr 24 which is-'cast integral with the outer casing-23,'so as to prevent the admission of acids-tol the interior .of the casing-and destroying the` resistance coil vcarried thereby, A cover'v vor cap v25 is adapted to fit cverrear'end of the casing 23 and is secured thereto by means of the screws 25%4 A nut '2 6 fitting in the j-astad' to' raise the piaI 6' the desired. aisanceA forward end of the casing 23, is internally threaded on the screw 3, and on the outer end of the tube 27 and holds their ends in an abutting position. The tube 27 passes through the tubular portion 24 and engages a nut 28 carried by the cap 29. A handle 2O is secured to the cap 29 and lits over the rear end of the tube 27. This tube 27 has a tapering bore which is adapted to receive a stlck of solder 30, the said tapering bore having its large diameter toward the tip 1, which will always leave the stick of solder free to move toward the screw 3.
To insert the stick of solder 30, the cap -29 and nut 28 are removed, allowing access to the bore within the tube 27 the stick 30 is then inserted, when the cap 29 and nut 28 are again replaced on the handle 20. A nut 31 screw threaded to the external threads 32 on the tube 27, is screwed down agalnst a shoulder 33 in the handle 20 and prevents the same, from being displaced when the cap 29 is removed.
Asbestos packing 34 is placed w1th1n the handle 20, and surrounds the ferrule 35, through which the tube 27 passes, and prevents the handle 20 from becoming too hot to be handled. Asbestos washers 36 are placed Within the nut 28, to prevent the solder 30 when melted from leaking out of the nut 28 when in an inverted position and hangin there when cooled off. Connecting posts 3 -are carried by Athe cap 25 and are entirely insulated therefrom, and these posts are adapted to be connected to wires leading to the source of current. The coil 22 is entirely insulated from the casing 23, by suitable insulation preferably a sheet of mica, to prevent short circuit. A ferrule 38 is adapted to take up the space occupied .by the casing 23, when the latter is removed for heating the iron in a furnace. The said ferrule 38 would be carried by the tube 27 between the nut 26 and tube 13 so as to prevent displacement Of the tube 13 and handle 20.
From the foregoing description of the various parts of the device the operation thereof may be readily understood. The solder is inserted within the tapering bore of the tube 27 by removing the cap 29 and nut 28 carried thereby. The contact posts 37 are connected by wires to any convenient source of current of the required voltage. The resistance element 22 will cause the heating of the tube 27 which will heat the tip 1 and also the solder 30 when the latter will begin to melt. Pressure on the linger piece 14 will cause the valve pin 6 to be raised from its seat 8. The solder will thereupon run out through the assage 9 and aperture 8 to the passage 4 an then out at the tip to the place Where it is to be applied. When the lever 11 is released the spring 19 will cause the pin 6 to seat so as to shut off the flow of solder. By removing or adding Washers 39 the tip 1 may be turned so as to bring the outlet on the side desired to suit the hand of the operator.
Various changes in form, proportion and minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention as defined in the appended claims.
Having thus described the invention, what is claimed is 1. In an electric soldering-iron, the combination of a tubular member having a tapering bore for the reception of a bar of solder, a casing carried by said tubular member, a resistance coil contained within said casing and surrounding said tubular member, anut carriedlby said tubular member, a screw carriedby said nut, a tip carried by said screw, said tip provided with a solder passage, said screw communicating with the tapering bore fin said tubular member for conductin the liquid solder to the exterior of the so dering-iron, a valve carried 'b said screw adapted to control the flow of iquid solder, a lever connected to said valve for operating said valve, a spring for kee in sald valve normally closed, and means ori'miting the throw of said lever, substantially as set forth.
2. In an electric soldering-iron, a hollow tubular member adapted to receive a bar of solder, a handle carried by said tubular member, a bushing carried by said handle and surrounding said tubular member, non-combustible acking surrounding said bushing and bearing against the inner wall of the handle, a detachable cap carried by said handle, an electrical heatin element contained within a casing, said casin and heating element surrounding said tu ular member at one end thereof, said electrical heating element adapted to be connected to a source of current for melting the solder, a screw member having passages for conducting the liquid solder to the exterior of the solderingiron, and a valve for controlling the flow of melted solder throu h said passages, substantially as set fort.
3. The combination in a soldering-iron, a tip member having a solder passage therethrough, ascrew carried by said tip member having two separate solder assages, one of said passages registerin Wit the passagein said tip member, the ot er passage registering with a receptacle adapted to contain a bar of solder, saidscrew provided with an aperture connecting the two separate passages, a valve adapted to seat in said aperture for controlling the fiow of liquid solder, a lever connected at one end to said valve, a handle engaging the opposite end thereof, a manipulatin screw carriedby said handle adapted to ajust the throw of the lever, substantially as described.
4. The combination in an electric solderlll tubular member, a detachable cap carried by said handle, a valve carried by said screw adapted to shut olf the flow of solder, a
