FLASH LIGHT MAGNET Nicola c; was... Welland, Ontario; Canada Application September a, 1934, Serial No. 142,994' s'o aims. (ours-sen I t The present invention relates to a small im- Figure 4isa detail sectional view taken throughplement or toolhaving controlled magnetic properties for extracting from the eye, skin and the likesmall particlesof iron, steel or other substances which may be attracted to a magnet; and hasfora main object to provide a construction of flash-light body crossing and a magnet'constructed and provided with a' socket adapted for interchangeable mounting on the flash-light body with the usual bulb or lamp so that the magnet may be operated by the dry cells and' by the switch device of the flash-light body.

fAnother objector the present invention is 'to provide a flash-light body of long, slender or,

thin construction-simulating a pencil or fountain pen and wherein the switch or circ closer may be incorporated in a clip structure for bolding the device frictionally to the clothing, such as in a pocket or the like and to provide a con-.

struction wherein the magnet may be quickly and easily interchanged with a light bulb when it is desiredfor use. j

A further feature of the present-invention is to provide a construction of magnet which may carry points of various characters constituting pole pieces for the magnet and which may be of-pointed rigid form, flexible or spring form to eilect a wiping or brushing" action when used, or which may be givenvarious other shapes, configuratio'ns or constructions for carryingout the particular purposes of use.

The invention further has an object to provide a simplified construction of implement or device which may be economically manufactured and which will not easily get out-of order, and wherein the dry cells used may be of any commercialmanufacture and may be quickly and easily interchanged or replenished in the usual manner at present employed inflash-light constructions.

With the foregoing and other objects'in view,

the invention will be more fully described hereinafter, and will be more particularly pointed out in the claims appended hereto. 1

In the drawing, wherein like symbols refer to like or corresponding parts throughout the several views} Figure I is a longitudinal section taken through a magnet deviceuembodying .the features of the present invention. Figure 2 is a detail enlarged section taken longitudinally through the detachable magnet.-

Figure 3 is a similar view showing a slight modification in the construction of the magnet wherein a fiexible'or wiping pole piece may be.used,

and

the flexible pole piece. h V r I Referringnow to the drawing. l designates the body portion or casing of a flash-light which is provided with ,aninsulating lining ll 'extend- 5 ing substantially throughout thelength of. the casing l 0. The casing is adapted to receive therein any desired number of dry cells I! providing a suitable source of electric energy foroperation of the device. The cells I! are of the usual construction having the exterior sheaths or casings of electric conduction material providing one pole of the cell and which are each provided with a central core or pole pieceMIS projecting beyond one end or the cell for electrical contact with the sheath or casing of. the next adjacent cell, Q or with the central contact portion of a lamp or the like, in the usual manner. The inner end of the casing 10 is closedby a'plug M or the like of any suitable construction and which in the present instance is shown as threaded into po-' sition so that the plug I 4 maybe removed for interchange or replacement of the cells II. In thepresent instance the plug I! is of hollow construction'and'carries therein a tension spring I5 adapted to bear against a follower or disc l6 ofpreferably electric non-conducting material and which is adapted to bear under tension of the spring I! against the bottom of the adjacent cell l2. Q. 1 I The outer end of thelcasing l0 has'secured therein, in any suitable manner, a lamp socket I! which isin electrical communication with the casing .Ill and is adapted to jreceive thc'plug l8 tion commonly used for holding plugs detachably in sockets and theplug I8 is provided in the 40 present instance with a centralcontact button or stud I9 adapted to register with the adjacent central pole piece l3 of the outermost cell For closingthe circuitthrough the cells l2, plug I8, socket I l'andthe casing III, the latter is provided with a metallic spring clip '20 secured to one side of the casing l0 exteriorly'thereof and which is of suflicient size and suitably located for securing thecasing Hi to the clothing; such, as to the edge of a pocket by frictional engagement of the free .'end of the clip 20 with the outer wall of the pocket for binding-the latter firmly against the side of the casing. Ill. The: free end of the clip 20 is provded with a head II. which may be of ball or other suitable shapevandwhich when (56 freed from the clothing may be depressed into an opening or slot 22 provided in the adjacent side of the casing i0 and the lining the head 2| may be forced into electrical contact with the adjacent exposed sheath of the dry cell I2.

The plug magnet of this invention comprises a shell 23 which is mounted on the outer end of the plug i8 and carried as a part thereof, the shell 23 being of suitable non -magnetic material and which is of sufficient size to partially fit at its inner end in the outer enlarged end of the socket [1, although any other suitable construction may be given the parts for carrying out the specific purpose for which they are intended. The shell l3 houses a coil 24 providing the body of a magnet having a core rod 25 which is secured in the outer tapering end of the shell 23 and which terminates ina polepiece or point 26 of any suitable configuration, such as conical as shown. The pole piece 26 is located at the apex or outermost point of the magnet so that it may be'applied in relatively small places and may be utilized for attracting relatively small particles of magnetizable material. The ends 21 and 28 of the coil 24 may be'connected in any suitable manner to the outer shell of the plug it and to the central contact piece or button it respectively of the plug for closing the circuit through the 001124 when the clip 20 is depressed.

In the modification shown in Figure 3, the core rod 29 projects through the outer end of the shell 23' and is threaded for the reception of a detachable nut 30 which carries a flexible or spring wiper finger SI of suitable width and construction for wiping contact over the surface of the skin, or for other desired applications.

This wiper 3| constitutes a brush and may be given various other constructions than as herein specifically shown. The nut ll and the wiper 3| are of course of magnetic material so as toconstitute a continuation of the magnet.

In use the magnet-isself-contained as the flash-light body carries the source of energy and the implement or device maybe readily carried by a doctor when called to remove fragments of ma'gnetizable material which may lodge in the eye or the skin, accessible to the usual hospital implements or a source-of current. I The device may be used as an ordinary flash-light with the usual bulb in the socket l1, and when it is desired to convert it toa magnet it is only necessary to interchange the bulb or light of the flash-light with the magnetiof this invention. In application the device is proportioned to flt the hand so that the point 26 or the wiper 3| may be applied to the skin or part of the body in which the metallic particles have lodged so that the application at a desired point so as to obtain the full force and effect of the magnet for withdrawing the magnetizable particles.

It is apparent that the casing I may be used as a support or holder for various other devices or attachments which are capable of use inconnection with a flash-light.

By useof the insulating lining II with the opening 22 in one side'thereof, the exterior paper or other insulating coverings or wrappers now used on dry cells may be completely removed so that the sheath or outer pole of v the dry cell will be protected by the insulating lining II and the exterior side of the adjacent dry cell l2 will be'exposed through the opening 22 so that the the pole rod 28 of H so that.

and where the patient is not may be made clip when compressed will make the proper electrical contact through the cell.

It is obvious that various changes and modifications may be made in the details of construction and design of the above specifically described embodiment of this invention without departing from the spirit thereof, such changes and modifications being restricted only by the scope of the following claims.
