FLASHLIGHT DEVICE Filed Jan. 17, 1942 Patented Feb. 16, 1943 FLASHLIGHT DEVICE Stanley Iwanowlcz, Detroit, Mich. Application January 17, 1942, Serial No. 427,138

(Ul. 24o-6.46)

1 Claim.

My invention relates to flash-light devices chiey of the kind adapted for use in conjunction with fountain pens, pencils, safety razors, and other small portable articles or implements, and its principal object is to provide a device of this character which is of small size, simple in construction, cheap to manufacture, and which is so designed as to concentrate the greatest possible amount of light upon the operative points or areas of the article with which it is incorporated.

With the above recited and other objects in view, I will now describe certain preferred embodiments of the invention, reference being had to the accompanying drawing, in which- Figure 1 is a longitudinal sectional view showing an electrically illuminated fountain pen having my device applied thereto.

Figure 2 is a fragmentary longitudinal section illustrating a modified form of the end which supports the pen.

Figure 3 is a longitudinal section corresponding to Figure 1, with certain modifications, as adapted for use with a pencil, and

Figure 4 is a fragmentary longitudinal section showing the invention as adapted for use with a safety razor.

Like characters designate corresponding parts throughout the several views.

Referring more particularly to Figure 1 of the drawing. the numerals I, '2 designate the two parts of the casing or holder, formed of transparent plastic material such as Lucite, a'nd connected together by screw means as indicated Within a cavity II in the part I is a tubular ferrule I2 which carries the pen nib I3 and the usual feeder plug which controls the flow of ink from the rubber sac I4, The free end of lthe part I is bevelled as at I5 and the opposite end has a cylindrical cavity I 6 having a spherical bottom I1. and the extreme end I8 of this part is formed as part of a sphere, for a purpose to be hereinafter explained.

The part 2 has a hollow portion 2i adapted to receive a single dry cell l having rounded terminais 4I, 42, and within the said part is secured a. threaded socket 22 int-o which is screwed alight bulb 5 having a lens 5I in front and a rear contact 52 which abuts upon the terminal 42 of the cell. To the socket 22 is connected one end of a iiat conductor 6, the other end of which is bent over the terminal 4I of the cell and normally in spaced relation thereto, so that by turning the thumb screw 1 in the end of part 2 the conductor may be brought against the said terminal to complete the circuit and thereby energize the bulb 5.

The surfaces Il and I8 of the part I and the outer periphery of the ferrule I2 maybe coated with some mirror-like material, so that part of the light from the bulb is reflected along the lines a: and outward into the operative area of the pen as indicated at y, while at the same time the balance of the light rays are diffused in a general way around the pen due to the transparent character of the material from which the part I is formed.

In Figure 2 is shown a modification of the end ol' the part I the outer surface of which is coincident with the part as a whole, while the bore, adjacent the ferrule I2, is tapered as indicated at I9.

Figure 3 of the drawing illustrates the application of my invention to a so-called "automatic" pencil of 'well-known type. In this case the barrel 8 of the pencil 82 has a bright surface as above described with reference to the ferrule I2 of the pen in Figure l.

The body or casing I in this modification is formed in a single piece as shown, and provided with an end plug 83 screwed therewithin so that inward movement of the plug operates to close the circuit of the battery and lamp, as will be understood.

In Figure 4 of the drawing is shown the adaptation of the invention for use with a safety razor 9, the shank 9| of which is secured within the cavity II as shown. while the end of the part I has its periphery flared outwardly as at 92 and its end rounded as at 93 so as to spread the light rays over a wider area.

'I'he construction of the pencil mechanism and of the razor may be of any conventional form well known in the art, and it is not deemed necessary here to describe them further.

It will be observed from the foregoing description and by reference to the drawing that I have provided a simple and eicient device which is well adapted to fulfill the objects set forth in the preamble of this specification, and while I have herein shown and described a preferred embodiment of my said invention, it will be readily understood by those skilled in the art to which the same pertains that various changes in detail may be made to suit any particular or peculiar requirement without departing from the spirit of my invention as defined in the appended claim. For example, the reflecting surfaces, which in the drawing are merely suggestive, may be modified in 'shape and location according to the best principles of the optical art, so as to project the light rays along the lines indicated at :c and thereby produce the desired illumination. Further, that part of the casing or holder which 5 ,contains the dry celly may be opaque or semiopaque so as to present a better appearance.

Having thus described my invention, what I claim and desire to secure by Letters Patent of the United States is:

A flash-light device adapted for use with an implement having an opaque shank. comprising a single piece of transparent material having at one end a central cavity for receiving said shank and at the other end a cavity for receiving a light bulb, a reflector in iront of the filament of said bulb for projecting the rays therefrom outwardly and rearwardly from said shank, an annular reflector behind said nlament adapted to receive said rays and to project them in an annular beam around and beyond said shank, and reflector means proximate said implement for deflecting said rays into the `operative area thereoi', whereby lall oi.' said rays are utilizable in said area.
