Patented Jan. 6, 1931 e Imam n. WEBB, or nnnn'onnqbn" '4 'nnno'mouaeumrc Hex-fir TOOL i I Application med runes, 19ao;; saiam;1 ,551]? I Myinvention relates to an electromagnetic I pick-up tool.
In accordance with my'invention, I provide an electromagnetic}.pickqip tool or imple-. l ment, which may e conveniently manipu-' lated for removing r'on elements from inac- CGSSIblG places.
The tool preferably embodies an electro-v magnet constitutingiia unit, and so wound as to besmall ands'trong in its electromagnetic force. The ele otromagnet is enclosed in preferably non-magnetic case to be protected thereby fro v oil, grease, water, or mild chemicals, whijc might tend to destroy the insulation of the llwinding. The handle of the device is preferably in the form-of a tube, having a relatively small diameter, whereby the tube may be bent at different angles to enable theitool to be inserted into inaccessible places. 'The tube carries the case andiis adapted to receivea lead wire connected withone end {of the electromagnetic winding, the other'end of the winding being connected with the case; The forward end of the case is formed open and this permits of the insertion of the lead wire, and the electromagnet into theftub and case, respectively in one operation. The end of the case is closed by ahead, preferably forming a part of the core of the "electromagnet. The coacting lead wire isattached to the tubular handle and a flexible "sleeve is preferably secured to the rear end of the tubular handle the following description.
for protecting the lead Wires. The tool is extremely simple inj'construction, strong, du
rable, and convenient ,in use.
Other objects advantages of the invention, will be apparent during the course of In the accompanying drawings, forming a part of this specification, and in which like numerals are employed to designate like v Figure 2 is a transverse section taken on line 2-2 ofFigurel, i v

The tubular handle has ia' r e'lati' vely' The devicejembo di'es electrb'inagn et in} serted within the ca-s65, andthis electromag f net includes. a spool -c'ore '8,"form'edfof"iron or the like, embodying end-"discsi and 10, The 'dis ol9 is "of'adiameterto fliave asliding fit within; the case 5, while the disc 10 has a diameter substantially "the same; as the ex- .terio'r' diameter of 'the ease". 3 The core 8 has awinding 11 thereon, formed'ofinsulated wire, as is well-known; :O'ne'end of the winding is e1e'ctric'ally connected with' 'the' case 5;
as shown at 12. The disc 10 maybe'rigidly' attachedto the case 5 byflany' suitable means, preferably by soldering at 13; for producing 5 The tubular handle of small diameter, and has a bore of small diameter for receiv ing 'an insulated leadwir'e '13, preferably haw mg a close sliding fittherein to close the bore. 7 This lead wire has electricalconnectionwith] g the opposite end of the winding 11 adjacent tothe 'disc'9l- The lead Wire 13 extends rear; wardly beyond the tubular handle and is equipped with a resilient clip 14, 0rthe like/ The other insulated'lead wire 15 may have a resilient clip 16, and'the -lead' wir'e 15 is Thenuinerall'? designatesa flexible protecti'ngg sleeve, preferably formed of a" wire coil, which is attachedto the rear end of the tubular handle 7 and receives the wires 13 .oo' the rear end of thetubular hank and 15 therethrough, preventing the insulation of-the same being injured.
" In the use of the device, the handle 7 by virtue of its small diameter may be angular- 1y adjusted or bent 'so that the case 5 may be a. e inserted into inaccessible places, while the handle 7 is sufliciently stiff to serve as a sup- I 7 port for the case. The handle 7 is, therefore,
' readily bendable. The wire 13 closes the bore forward disc having a diameter larger than.
' of the tubular handle, thereby sealing the rear end of the case. The two lead wires '13 and 15- may be connected with the opposite oles of the source of current, and whenthi's 7 10 1s done, the electromagnetis 'energize'cl"ancl"""' V the metal base will be attractedtothe,elemoeia v ..-.i:.
