Description
Patented Dec. 17, 194i) FLASHLIGHT DEVICE Samuel Osterman, New York, N. Y., asslgnor to Guth Stern & Co., Inc., a corporation of New York Application June 22, 1939, Serial No. 280,454 '2 Claims. (Cl. 240-646) This invention relates to flashlight devices such as carried in the pocket or purse, or used in combination with instruments, as for example, incorporated in the body of an electrically lighted mechanical pencil, or in the handle of a similarly lighted screw driver, safety razor or the like hand tools.
Among theobjects of the invention is to improve devicesof the character described comprising few and simple parts which are readily assembled and incorporated in bodies or handles of instruments and in hand tool structures, which shall form attractive appearing, small, light-weight and compact articles adapted to be carried conveniently about the person, which shall be capable of withstanding rough and hard service without becoming inoperative, which shall be cheap to manufacture, which shall permit ready and easy replacement of conventional or standard parts such as batteries and lamps, and which shall be practical and efiicient to a high degree in use.
Other objects of this invention will in part be obvious and in part hereinafter pointed out.
The invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be exemplified in the construction hereinafter described and of which the scope of application will be indicated in the following claims. V
In the accompanying drawing, in which is shown various possible illustrative embodiments of this invention,
Fig. 1 is a front elevational view of an electrically lighted screw driver made to embody the invention, partly broken away to expose the interior construction.
Fig. 2 is a fragmentary front elevatlonal view of a light projecting end of an embodiment of the invention showing the provision of a cover cap for said end and a plurality of interchangeable instruments or tools; for use on said end when the cover cap is removed.

Fig. 3 is a fragmentary front elevational view showing an electrically lighted pencil end of another embodiment of the invention.
Fig. 3a is a fragmentary front-elevational view of the switch control end of .the electrically lighted pencil shown in Fig. 3, and
Fig. 4 is a front elevational view of another modification of the invention showing an improved construction embodying an electrically lighted razor.
The invention may be embodied in various electrically lighted articles which are adapted to be carried about the person either in the pocket, 5 purse or in a toilet kit. An embodiment of the invention incorporating an electrically lighted screw-driver 20 as shown in Fig. 1, will first be described.
Said screw-driver 20 is seen to comprise a body 10 or handle 2| which preferably is formed of a metallic tubular casing for housing an electric dry cell 22 of conventional or standard construction. A free end2ia. of said handle-casing 2i may be provided with a suitable switch 23 which 1| is constructed as shown and operates in the manner hereinafter described. The other end 21bof said handle-casing 2| has removably mounted thereon a hollow, transparent conical shaped member 24, the smaller tapered .end 24a of which 30 terminates in a screw-driver blade 25. The larger end 24b of member 24 is seated on the handle-casing end. 2lb by means of a suitable coupling 3!, which, as shown in Fig. 1, may be of screw Joint type. I
To releasably lock the member 24 to the handlecasing 2| at said coupling 3i, there may be provided a suitable fiat spring 32 which is anchored by one end thereof at 32a to the handle-casing end 21b. Said spring 3| carries on its free end 30 a projecting pin 32b which is adapted to pass through the handle-casing end 21b at coupling 3! and engage said large end 22a of member 24 to prevent any relative movement of the latter with respect to the handle-casing 2| when the 35 above described releasable locking means is in efl'ective position as shown in Fig. 1. To release said-locking means the flat spring 32 is sprung out to withdraw the pin 321) from its effective engaging position to permit the unscrewing of member H from the handle-casing 2! at the coupling 3!.
The member 24 may be made of a non-metallic material such as lucite or other similar molded so-called plastic product. Said tapered end w 24a of said member 24 carries a metallic holder 26 firmly secured thereto from which the screwdriver blade 25 extends. Said holder 26 is seen to comprise a. socket portion 26a for anchoring the shank 25a of the blade 25 and a band 26b 5 encircling the exterior of said smaller end 24a; said socket portion 26a and band 26b being constructed to serve as a reinforced seat for the blade 25 as shown in Fig. 1. If desired, a pin 26c may be provided to positively retain the member 51 24, holder 26 and blade 25 against relative movement.
Within the handle-casing end 2|b an electrical and the cell terminal 22a with one spring end 29a of said spring 29 electrically connecting with the lamp screw base 21b, the other spring end 2% of said spring 22 being positioned to contact the shell 22c for the battery cell 22. The spring 29 normally keeps the electrical circuit open between said lamp center terminal 210 and cell carbon terminal 220. as shown in dotted lines in Fig. 1.
The electrical circuit for supplying current from the battery cell 22 for lighting the lamp 21 is controlled by switch 23 at the handle-casing end 2|a. Said switch 23 may be of any suitable construction for moving the battery cell 22 within said handle-casing 2! against the action of spring 29 to cause the lamp base terminal 210 to contact the battery cell terminal 22a as shown in full lines in Fig. 1.
The switch 23 may comprise of a screw portion 23a which is threaded into the handle-casing end 2|a. for abutting the bottom end 22b of the battery cell 22 within the said handlecasing end ZIa, the threaded portion 230. having a head 23?) for manipulating said switch 23.
If desired, the screw driver may be provided with a pocket clip 30 which may be permanently attached to the handle-casing 2| by prongs 30a. in any conventional manner.
With the parts of screw driver 20 constructed as described above and assembled as shown in Fig. 1, it may be utilized by grasping the handlecasing 2| and manipulating the screw driver 20 in the usual manner after engaging the blade in the head of the screw (not shown) in the well understood manner. Illumination at the working region where the blade 25 is to be used is provided by turning of the head 23b of the switch 23 for moving the battery dry cell 22 in the handle-casing 2| until the circuit to the lamp 21 is closed. The light beams or rays from said lamp 21 pass through the member 24 and thus illuminates the working arcato which the blade 25 is applied. When light from the lamp 21 is no longer required the head 23b is turned to permit the battery cell 22 to be moved by the action of the spring 29 within the handle-casing 2| for breaking the circuit.
The releasable locking means positively holds the member 24 to the handle-casing 2| so that they act as a single integral unit and is rigid to take care of any stresses or strains to which the screw driver 20 is subjected in turning movement in a clockwise or counter-clockwise direction, the coupling 3| and said locking means also serving to retain said member 24 and handlecasing 2| against any ossible separation.
For replacing the battery 22 or lamp 21 the spring 32 is moved releasing the pin 32b to permit disconnection of the screw coupling between the member 24 and the handle-casing 2|.
When the screw driver 20 is carried around for use in the pocket, at supporting portion of the users garment is engaged between the clip and the casing 2| (not shown) in the well understood manner.
In Fig. 2*there is shown the provision of a cap 40 for covering the member 24. The use of such cap 40 .is contemplated where there is a modification of the invention in which a blade I25, which corresponds to the blade 25 of the screw driver 20, shown in Fig. 1, is interchangeable with other instruments seated on the holder I26. Such instruments or tools may be a reamer 4|, an awl 42 or other like tools, the shanks of the blade I25, reamer 4|, awl 42 and the like being interlockingly secured in place on the holder I26 as shown in Fig. 2a. Those instruments, when not in use may be removably mounted on the inner side of the closed end 40a. of the cap 40 and may be so arranged that they nest between the member 24 and the wall 40b of the member 40 as shown in Fig. 2. Said closed end 40a of the member 40 with the instruments mounted thereon may be made to be detached from the wall 40b so as to facilitate dismounting of said instruments.
In Figs. 3 and 30. there is shown a modification of the invention embodying the construction of an improved pencil light 220 instead of a screw driver. Said construction may be similar to the screw driver 20 above described with the exception that the holder 26 on member 24 is replaced by a suitable mechanical lead pencil mechanism 226 of any conventional construction, preferably one in which lead 226a is releasably retained therein. The switch 223 shown in Fig. 3a instead of having the head shaped like that for screw driver 20 as shown in Fig. 1 is terminated in a cylindrical rubber tip 2231: which is adapted to be used as an eraser 223?) for the pencil light 220. The pencil light with the eraser may be used in the well understood manner with or without light for the lamp 21 in the same manner as described above for the screw driver 20 and controlled by the switch 223.
In Fig. 4 is shown a further modification of the invention as applied to the construction of an improved razor light 320 instead of a screw driver 20 or a pencil light 220. Said construction may be similar to that of the screw driver 2|l'or pencil light 220 with the exception that the holder 26 and the mechanical lead pencil mechanism 226 is replaced by a mounting 326 on which a suitable head or holder and guard 325 of a safety razor is mounted. Since this razor light 320'would generally be carried in a kit or other suitable container, the clip 30 may be dispensed with.
In using both the pencil light 220 and the razor light 320 there is usually very little or no twisting strains between the parts corresponding to the member 24 and the handle casing 2|, the releasable locking means may also be dispensed with, if desired.
The razor light may be used with or without the light from the lamp 21 in the same manner as described above for the screw driver 20 and pencil light 220 and controlled by the switch 23, the razor portion manipulated and used in the well understood manner.
It will thus be seen that there is provided means whereby the several objects of this invention are achieved and which are well adapted to meet the conditions of practical use.
As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiments above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawing carried at one end of said casing for cooperating with said cell, an electric incandescent lamp insertable into the other end of said casing and resiliently mounted to extend therein, said lamp ,ncrmally being disconnected from an electrical circuit with said cell and being connected in circuit through operation of said switch, a transparent member extending from said last mentioned casing end through which light rays from said lamp pass to serve as a cap over said lamp and as an abutment for retaining the lamp in the casing, threaded coupling means integrally formed on the casing and member for attaching said member in position at said last mentioned casing end, means within the casing movable with the lamp base and mounted inwardly of said coupling means for retaining a center terminal of the lamp base in alignment with a central ter-- minal 01' said cell. releasable spring locking means mounted on the exterior of said casing having a portion thereof projecting through the coupling means beyond said means movable with the lamp base, said coupling means including openings in the casing and said member adapted to be moved into registered ali nment for receiving said lockingmeans portion. and an instru- -ment terminating said member so constructed and arranged to have a region where the'instru-- ment is to be used lighted by rays passing through the member from said lamp during the manipulation of said instrument; themandle-casing,
