PICKER MAGN ET.
application mea January s, 1921. semi m. isaaes.
This invention relates to magnetic tools and has particular reference to an electromagnetic tool for picking or removing fallen nuts, bolts and other steel articles from the mechanism of an automobile or other pieces of machinery or from places that are not easily accessible.
The principal object of the invention is to provide an improved magnetic picking tool that may be bent or deformed to reach around obstacles or into inaccessible places.
Another object of the invention is to provide a bendable magnet which may be readily deformed or bent to adapt its entrance into inaccessible places.
Another object of the invention is to provide such a picker magnet with a simple inexpensive handle that may be easily bent as desired to reach inaccessible places and also to form an opening and closing switch for electrically energizing or de-energizing the ma et.
Anot er object of the invention is to provide simple, inexpensive and eiiicientelectroma `etic picker means adapted'to be deforme to avoid obstacles and to reach inaccessible places.
Other objects and advantages of the invention will become ap arent from the following specifications ta en in connection with the accompanying drawings. It will be apparent that many changes may be made 1n the details of constructionA and arrangement of parts without departing from the spirit of the invention as falling within the accompanying claims, hence I do not wish to be bound to the exact details shown and described, the preferred forms only having been shown by way of illustration.
Referring to the accompanying drawings,
Figure 1 is a top or plan view of the invention;
Figure 2 is a partial cross'section on line 2--2 of Figure 1;
Figure 3 is 'a cro section on line 3 3 of Figure 1, and
Figure 4 is a cross section on line 4`-4 of Fi re 2.
eferring to the drawings in which corresponding reference characters denote corres onding parts. throughout, Fig. 1 shows t at the invention comprises a bendable magnet 1 made of sot bendable Norway iron, a bendable handle portion 2 which is a continuation of the magnet, and the current leads or` wires 3 twisted around the portion 2'.
O ver the magnet 1 is wound the wire coil 4, Fig. 2, for energizing the magnet 1. Over the coil 4 is placed the insulation wrapping 5. The end of the magnet 1 is fashioned into a plcker nose or face Gadapted to pick up iron or steel objects when the magnet is energized. One of the leads 3 is attached to an insulated metallic rim 7 which fits over an lnsulating ring 20 surrounding the magnet, as shown in Fig. 2, and contacts with one end of the coil 4 around the magnet 1. The o posite end of the coil 4 is soldered at 19 to t e magnet 1 and the other lead 3 is attached to a metallic band 8 fitting around an insulation ring 9, Fig. 3, which fits around the portion 2. The two leads 3 are attached to the source of electric current 10 at the posts 11 and 12 respectively. The end of the handle portion 2 is bent at 13 until the extension 14 beyond the bend lies substantially parallel with the main body of the portion 2.
To energize the magnet 1 the extension 14 of the portion 2 ispushed or bent in until it contacts with the metal ring 8, as indicated in dotted lines in Fig. 1. This com letes .one lead direct to the magnet throug the portion 2. The other lead attaches directly to the coil 4 around the magnet 1, as has been described; hence when the contact is made at 8 the magnet 1 is energized'.` Both the magnet land the handle portion 2 may be vbent or deformed as. deslred to avoid obstacles between the operator and the object to be picked up.` The tool is held in the hand of the operator at the bent ortion 14. Electric energy may be furnished rom a battery or other source of electric energy. When the ma et 1 is energized the picker face 6 will pic up iron or steel objects within the limits of its magnetic capacity by contacting the face 6 with the object to be picked up.
From the foregoing description it will be seen that "I have provided simple, inexpensive and efficient means for withdrawing iron land steel objects from inaccessible places, which means are ad'ustable to avoid obstacles, and which provi e a hand and easy operable tool for carrying out t e objects of the invention.
Having described my invention, I claim:
1. An electro-magnetic tool comprising a pliable core formed of a single rod of soft flexible magnetic wire, a conductor coil wrapped around a portion of said core, an
electric circuit means connected with the so i' conductor coil, one end of the core havin a around a portion of the magnetic portion adbent portion lying substantially parallel with jacent the picker nose having one end sethe body of the core, and an exposed elec-f cured to the magnetic portion and the other trical contact point in the circuit associated with the body of the core and aligned with and spaced from the end of the bent portion o f the core whereby the electrical circuit may be completed by pressing the end of the bent ortion of the core against the exposed electrical contact point to energize the conductor coil and magnetize the portion of the core surrounded by the coil.
2. An electro-magnetic tool comprising a pliable core formed of a single rod of soft Hexible magnetic wire, a conductor coill wrapped around the core adjacent one end thereof, electric circuit means connected with the conductor coil, one end of the core havinor a bent portion lying substantially parallel with the body of the core and an exposed' electrical contact oint in the circuit associated with the bo y of the core and ali ed with and spaced from the end of the ent portion of the core whereby the electrical circuit may be completed by pressing the end of the bent portion of the core against the exposed electrical contact point to energize the conductor coil and magnetize the portion of the core surrounded by the coil.
3. An electro-magnetic tool comprising a bendable iron having one end finished. into a picker nose and the other end bent untll the terminal portion lies substantially parallel with the body thereof, a Aconductor coil to an insulated conductor plate supported by the magnetic portion, a second insulated conductor late su ported by the magnetic portion a jacent t e bent end thereof, a pair of electric leads, one'being attached to the lirst insulated late and the other to the second insulate plate, an exposed contact point at the second insulated plate whereby the bent end of the magnetic portion may be pressed to contact with the contact point to close the circuit and energize the magnet.
4. An electro-magnetic tool com rising a bendable magnet portion of a sing e rod of soft magnetic iron havin a hand portion which is a continuation o the ma et portion bent to be substantially paral el therewith, electric leads carried by the magnet portion, a conductor coil surrounding a portion of the ma et portion adjacent one end having one en secured to the magnet portion and the other to one of the electric leads, an insulated support on the magnet portion havin an exposed contact point and aligned with t e bent portion of the magnet portion and connected to the other electric lead whereby the circuit will be closed when the bent portion of the magnet portion is pressed against the contact point to energize the magnet portion surrounded by the con-A ductor coil.
