PENCIL-LIGHTING ATTACHMENT.

Specification of Letters Patent.

Patented one. 1, mile.

Application filed March 23, 1917, Serial No. 156,911. Renewed February 27', 1918.' Serial No. 219,539.

To all whom it may concern:

Be it known that I, JERRELL BENNETT, a citizen of the United States, residing at Grapevine, in the county of Tarrant and State of Texas, have invented new and useful Improvements in Pencil-Lighting Attachments, of which the following is a specification.

This invention relates to illumination,

and more especially to portable, self-con-.

tained devices for permitting the illumination of a portable article when desired; and the object of the same is broadly to com bine an electric lamp with a pencil, pen, or the like mounted within its. casing, so that the lamp may be illuminated to light the surface being written on.

The invention is carried out as more fully set forth in the following specification and shown in the drawings wherein Figure 1 is a central longitudinal sectional view of this device complete, showing it adapted for use in connection with a pencil point.

' Fig. 2 is a perspective'detail showing how the point protrudes through the annular lamp or bulb.

Fig. 3 is an enlarged sectional detail of the annular lamp itself.

Fig. 4 is an enlarged sectional detail showing the circuit closer 1n a different position from that shown in Fig. 1. t

In the drawings the numeral 1 designates the pencil case of tubular formation, and 2 is the removable cap at its front end which when applied covers the tip of the pencil 3. I desire it understood that where I herein speak of a pencil as shown in the drawings,

it is quite possible to substitute some other article such as a pen or brush. The rear end of the case in the present instance is open,- and temporarily closed by another cap or closure 4. When this is removed access is had to the interior wherein is stored a battery 5 of any appropriate type. Across the case at about 1ts midlength is a partition 6, forward of which the pencil or other instrument 3 is mounted therein in any suitable manner.

In Fig. 3 is best seen the form of lamp or bulb which I preferably employ in this connection. The samehas an annular body 10 of glass hermetically sealed as usual, and an annular threaded shank 11 :which screwed into an appropriate socket 21 within the casing, and the filament 1-2 is indicated in the battery or batteries 5.

this view as extending completely around the annular body and making convolutions or disposed in other zigza paths therethrough, the extremities of t e filament being connected with the

lead wires

22, 23 as;

shown. The wire 22 is carried down within the. case as seen in dotted lines and connected with the lower end of the battery '5 in a manner not necessary to describe in detail. But an important feature of my invention is the switch or button for throwing the lamp into or out of electrical connec- I tion with the battery. This is shown in Fig. l as part of the ordinary pocket clip 13 by means of which the case is held to the edge of the vest ocket or the like when it is not in use. T is clip is shown as having a knob or ball at its free end, and its other end is rigidly carried by an insulated button '14 slidably mounted in a slot 15 in the'side of the casing and in constant contact with the wire 23, the latter being held to but insulated from the casing as at 24 and leading to the bulb asshown. Secured at an appropriate point in the wall of the casing and insulated therefrom is a contact from.

which a wire 26'leads to the upper end of The parts are shown in ig. 1 with the circuit broken, because the ball of the clip does not touch the contact 25. In this condition the operator inserts the device in his pocket and the edge of the latter passes under the ball. In fact. if he should insert the device in his pocket when the parts stand as seen in Fig. 4, the

edge of the pocket would pass between the ball and the contact 25 and the circuit would point 3 onto the matter being written. The

fact that the lamp is annular and the filament extends all around the pencil, prevents the latter from casting a shadow onto that portion of the pa er on which the user is about to write, an therefore I consider this is a decided improvement over such an arrangement in which a small lamp or bulb stood alongside the pencil or other instrument. -Detellsother than as herein set-forth are unimportant. I

What is claimed -as new is: The herein described illuminated pocket instrument including a casing containing a source of electricity and having a slotin one side, an insulated contact in the saline slde of the casing connected with one pole of said source, a lump csirried by the casing and connected with the, opposite pole of said source, a wire leading from the lamp-socket within the 'casin along said slot, a button slidably mounte in said slot in contact with such wire and. insulated from the cas-. ing, and a spring pocket clip carried by the button andhaving its free end adapted to touch said Contact when the button is at one extremity of the slot, for the-purpose'set forth.

In testimony whereof JERRELL BENNETT.
