3. Claims. (01. Mil-6.46)

The present invention relates to new and useful improvements in light attachments for pens and pencils and has for its primary object to provide a self-contained lamp of the flashlight type which is adapted to. be expeditiously mounted on a pen or pencil in a manner to facilitate writing in the dark.

Another important object of the invention is to provide a novel combination of clip and circuit controlling switch for the flashlight.

Other objects of the invention are to provide an attachment of the character described which will be comparatively simple in construction, strong, durable, highly efiicientand reliable in use, light in weight, compact and which may be manufactured at low cost.

All of the foregoing and still further objects and. advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawing wherein like characters of reference designate corresponding parts throughout the several views, in which:

Figure 1 is a view in side elevation of an attachment in accordance with the present invention, showing the same mounted on a pencil.

Figure 2 is a view principally in top plan of the invention, portions of the flashlight being broken away in horizontal section.

Figure 3 is an end'elevational view.

Referring now to the drawing in detail, it will be seen that the embodimentof the invention which has been illustrated comprises a flashlight of the portable, battery type which is designated generally by the reference numeral I, said flashlight including a cylindrical casing 2 which is closed at its rear end and open at its forward end for the reception of a socket 3 into which an electric bulb 4 is threaded. The socket l includes an external flange 5 with which the forward end of the casing 2 is in abutting engagement.

The casing 2 of the flashlight I has formed therein, at an intermediate point, a longitudinal slot 6 in which a slidable switch contact I is operable. The reference numeral 8 designates a conventional dry cell battery which is mounted in the casing 2 and which has a terminal electrically connected with the filament in the electric bulb l at all times.- The other terminal of the dry cell battery 8 is the outer shell thereof against which rests contact 1. The contact I is operable between the battery 8 and the casing 2, said contact being formed from a single strip of substantially flat metal whichis bent upon itself in a manner to provide a loop 9, side abutting intermediate portions l0 and oppositely extending end portions H.

The reference numeral l2 designates a resilient combination clip and contact flnger which is 5 formed integrally with the flange 5 and which extends rearwardly therefrom adjacent the casing 2 in spaced relation to said casing. At its free end, the member l2 terminates in an outwardly curved end portion l3 with which the loop 9 of 10 the slidable contact I is engageable for completing the electric circuit which includes the filament of the electric bulb 4. Of course, it will be understood that the socket 3 is of current conducting material. Also integral with the flange 5 is a 1' light shield and reflector ll.

The reference numeral l5 designates a conventional pencil upon which the flashlight l is mounted in spaced, parallel relation thereto through k the medium of a double resilient clamp l6. Of 20 course, the invention is also intended for use on various types of pens and other writing. instru- V merits.

In use, the pencil is held in the usual manner for writing. When artificial light is desired, the 25 slidable contact 1 is moved forwardly into engagement with the resilient contact l2 for illuminating the lamp 4, as will be understood. Either the flashlight l or the pencil 15 may be conveniently slipped out of the clamp l6 when e- 30 sired.

It is believed that the many advantages of a light attachment for pens and pencils in accordance with the present invention will be readily understood, and although a preferred embodi- 35 ment of the invention is as illustrated and described, it is to be understood that changes in the details of construction and in the combination and arrangement of parts may be resorted to which will fall within the scope of the invention 4 as claimed.

What is claimed is:- a

1. A flashlight including a substantially cylin drical casing closed at its rear end and open at its forward end, said casing having a longitudinal slot 5 at anintermediate point, a dry cellbattery in the casing, a socket of current conducting material mounted in the forward end of the casing, an electric lamp mounted in the socket and engaged with the battery, an external flange on the no socket engaged with the forward end of the easing, a resilient contact integral with the flange and extending therefrom adjacent the casing in spaced relation thereto, and a slidable contact operable in the slot and engageable with the resilient contact and resting against the outer shell of the battery and in the lamp circuit for controlling said larnp circuit.

2. A flashlight including a casing open at its forward end and having a longitudinal slot therein at an intermediate point, a socket of current conducting material mounted in the casing, an electric bulb mounted in the socket, a battery in the casing engaged with the bulb, a resilient contact mounted on the socket, and a slidable contact operable in the slot and bearing against the outer shell of the battery and engageable with the resilient contact, said slidable contact formed from a single strip of substantially flat metal in= eluding a loop engageable with the resilient con= tact, a pair of side abutting intermediate portions P operable in the slot, and a pair of oppositely extending end portions slidable in the casing between said casing and the battery. 3. A flashlight including a'casing open at its forward end and having a. longitudinal slot therein at an intermediate point, a socket of current conducting material mounted in the casing, an electric bulb mounted in the socket, a battery in the casing engaged with the bulb, a resilient contact mounted on the socket, and a slidable contact operable in the slot and bearing against the outer shell of the battery and movable into and out of engagement with the resilient contact to energize and deenergize the filament oi the bulb.

A GODMAN.
