ELECTRICALLY-LIGI-ITED PENCIL.

Application filed October 19, 1914. Serial No. 867,498.

lb 07/ 1 '7102/2 1'2 may concern:

Be it known that I. 'lLLis Q. BROWNE. a citizen of the l nited States. residing at Boston. in the county of Suffolk and State of Blassachusetts. have invented certain new and useful Improvements in Electrically- ].ighted Pencils: and I do hereby declare the following to be a full. clear. and exact description of the invention. such as will enable others skilled in the art to which it appertains to malte and use the same.

This invention comprehends certain new and useful improyements in electrically lighted pencils and has forits primary object to provide a deviceof this character which will be of exceedingly simple construction as well as cheap to manufacture and highly etiicient in use.

The inventionhas for another object to provide a device of this nature including supporting and holding means for a pencil removably connected with a flash light and constructed in such manner as to not obstruct the rays of light emanating from the bulb of the flash light.

'lhe invention has for another object to provide a pencil holding member of this character which will be of exceedingly simple construction and operation as well as light in weight and cheap to manufacture and is formed in such manner that it may be readily secured to the flash light and the pencil positioned in the holder or removed from the same.

The invention. has for a still further object to generally improve and simplify the construction and operation of devices of this character and increase the etliciency thereof without materially increasing the cost of the same.

With the above and other objects in view as will become more apparent as the description proceeds, the invention consists in cer tain novel features of construction, combination and arrangement of parts as will be hereinafter more fully described and claimed.

For a complete understanding of my invention. reference to be had to the following description and accompanying draw ings. in which:

Figure 1 is a longitudinal section of the preferred form of my invention with a pencil secured in position in the holder. Fig. 2 is an elevation of the pencil holder removed.

Fig. 3 is an enlarged fragmentary elevation of the torm of flash hght upon which I preter tosecure the pencil holder. showing the manner in which the circuit is completed b v an inward pressure upon the spring mounted on the outer face of the casing of the flash light.

Referring more particularly to the drawings in which similar referencecharacters designate corresponding parts throughout the several views. 1. designates the casing of a flash light upon one end of which is threaded the large inner ring "2 of my improved pencil holder from which project the spaced arms which are brought closer together at their Jim-ward ends. as shown at l and secured to the small ring 5 through which the pencil 6 may be removably engaged. said pencil being secured'in position by means of the screws 7 engaged in the small outer collar 5 and also the larger screws 8 engaged through the arms 3 of the pencil holder. It will therefore be seen, that the pencil 6 may be readily adjusted in the holder and secured in adjusted position. In this form of the device the electric bulb 9. threaded in the forward end of the easing 1. as shown at 10 is inclosed by the arms 5) which are narrow and formed of thin metal in order that the arms may not materially interfere with the radiation o light from the bulb 9.

It will be umlerstood that the bulb 9 is engaged with one end of the dry battery 11. as shown at 12. while the opposite end of the dry battery is engaged with the removable top 13 secured on the opposite end of the casing 1 by means of the threaded flange 1-1 or by any other suitable means. The end of the dry battery. 11 is connected with the removable top 1?. and bearing against the same. as designated by the numeral 15 and it will be understood that. the dry battery 11 provided with a suitable wrapping 16 of insulating material to insulate the same from the casing 1.

A little section of the wrapping 16 of insulating material is cut-away. as shown at Specification of Letters Patent. Patented Sept. 28, 1915.

17 in order to expose the dry battery 11 at,

by means of a leaf spring 20 to space the 1nner end of the.push button 18 from the dry battery 11, it being understood that the leaf spring 20 is carried by the outer casing 1.

' ga'ged outwardly of the button 18';' whereby inwardpressure upon the free end of the spring 21,will serve to force the push button 18 inwardly against the small leaf spring 20 against the 'dry battery 11 to complete the circuit and light the bulb' 9 to furnish' illumination, in'order that the pencil 6 may be used. As soon, however, as the pressure upon the spring 21 is released, the spring 20 will serve to force the button 18 outwardly and thereby break the circuit.

From the foregoing it will be readily seen that I have provided an electrically lighted pencil which will be of exceedingly simple construction and operation and which may be readily secured upon or removed from a flash light or adjusted with respect to the same. i

While the preferred embodiments of the invention have been shown and illustrated it will be understood that minor changes in the details of construction, and arrangement of parts may be made without departing from thespirit and scope ofythe invention as claimed or sacrificing any of the advantages thereof.

\Vhat is claimed is A device of the class described comprisingthe combination with the threaded end of a flash light casing and'a bulb projecting from'the same, a holder screw threaded upon the threaded end of said casing, said, holder having its free end curved inwardly and secured by a pencil. receiving ring, said holderprovided with a plurality of screws for adjustably supporting a pencil therein and means carried by said casing completing a circuit through said bulb.

In testimony whereof I afliX my signature in presence of two witnesses.
