SOLDERING-TOOL Speciiication `of,2|f..e1:cers Patent. Application filled Mayv21, 1909. Serial No. 497,481.

Patented May 10, 1910.

To all whom it may concern:

Be it known that I, ALEXANDER A. BE- DARD, a citizen of the United States, and a resident of Detroit,-in the county of Wayne and. State of Michigan, have-invented a new and Improved Soldering-Tool', of which the following is a specification.

l Fig. 7 is a cross section on the line 7-7 ofV This-invention relates to sldering tools of the type provided with a reservoir in the head for retainin `.'a. supply'fsolder in a molten state for Ilelivery as required, and its object is to provide a tool oi this kind whichrshall be easily controlled, which shall have a removable cover for the reservoir in Vthe head, and which shall have a spring- Fi 1. ,y

imilar reference characters refer ,to like partsthroughout the several views.

The head 1 of' the tool is of copper or.v

A l other suitable metal and is secured onto the forked rod 2, the ends 3 of which ma'y be laced in the mold when-thc head ispast. he head is vprovided with a chamber 4', which may have a conical bottom as shown' in Figsa 1 and 2, or it may have a bottom such as shown in Fig. 3. To the upper end of the head is pivoted a cover or cap 5, preferably of copper, which has an opening 6 as shown in Fig. 4. A valve 7 also preferably of copper, is adapted to close the openjecting from the wall of the openin ing 6, and 1s provide with downwardly extending fingers 8 which are slidable in, the

ooves 9 between the shoulders 10. proas shown in Fi 4. After 4the fingers ave been slipped own through these grooves 9, the lower ends may be turned over as shown inFig. 3. Should gases collect within the chamber in the head, the valve 7 can be lifted off by the pressure of the gases so they may escape. At the upper end of the rod 2 is a handle 12 having a fcrrule 13. This ferrule has a small projection or catch 14 extending downward.` The valve-stem 15 has a sleeve 16 surrounding and slidable on its upper end.V This sleeve is provided with a slo't 17 through which the pin 18 extends, and thus prevents the sleeve from slipping 'oli the end of the stem. A spring 19 is mounted within the sleeve and holds it outward. The rod 2 is groovcd as shown 4in Fig. 7 to receive the stem and sleeve; lVlin the parts are in the position shown in Fig. 2,' the spring will hold the valveI 7 'on 'itsscat but will permit the valve to move from its seat under pressure, the small catch 14 holding the stem in the position shown. When it is desired to fill the chamber with melted solder, the sleeve 16 is pulled down so as to free it from the catch 14. when the stem can be swung. out and thus lift the cover from lover the chamber 4, which can then be filled.

Pivoted on the bolt 20 carried by the ferrule is a lever or handle 21, to which is connected the valve-rod 22. This rod extends through a notch 23 in the cover and a groove 24 in the head, and its lower pointed end 25 is adapted to close the passage 26.

AAny desired lneans may be used to hold the end 25 of the valve rod over the opening of the passage 26. The device shown in Fig. 2 is a bent spring 28 havingone end inserted through the eye 29 ou the errule and the other engaging the handle.

When the tool is to be used the sleeve is released from the catch 14, and the cover 5 swung open so that the chamber 4 inthe previously heated head may be filled with melted solder. The cover is then Kclosed, the engagement between the sleeve 16 and the catch 14 holding. it in position, and the spring 19 holding the parts down sufficiently tight to prevent leakage. Whenever solder is required, the handle V21 is pressed down,

thus opening the passa e 26, and permitting This consolder-to run down t e same. struction is especiall adapted for the preferred form of hea s which is practically'- rectangular in cross section with a tapering point.

Havin now explained my improvements', what I c aim as my invention and desi-re to secure by Letters 1 atent is 1. In a solderin tool, the combination of a chambered hea a cover hinged to the upper end of the same, a handle upon which the head is mounted, and a spring held device mounted on the handleto secure the cover in position.

2. In a solderin tool7 the combination of a ehambered 4hea a cover hinged lo the upper end of the same, a valve'for closing an opening inthe cover, a handle for the head, and a rod normally held against the handle and connected to the valve al its lower end to hold the same in closing position.

3. In a soldering tool, the combination of a ehambered l1ead,'ae0ver for lche upper end of the same provided with an opening, a valve closing said opening, an upwardly extending stem seeured to said Valve, and -a spring to hold said stein in proper position.

4. a stem having o'e'einl' forked, a ehainbered soldering-head on the ends of the fork, a handle on the opposite end, a cau-h on said handle, a cover at the upper end of the 4head In a soldering tool, the combination ol y to 'close' the opening', said cover having an opening", a valve to close the opening and ha ving gllille-lingersextending Lhereth rough, asteni connected yto said'valve, a sleeve on the end of the stein, a spring within the sleeve to hold the saine in engagement with the calc-h on the handle, said head havinr a passage through its lower gelul, a rod extending' ironl the handle inlo the head lo said passage, and spring-held means `to force the end of the rod into saidpassage lo close the same.y
