Specification of Letters Patent.
Patented Jan. 18, 1916.
Application filed March 23, 1915. Serial No. 16,361.
' at Stanwood, in the county of 'Snohomish and State of Washington, have invented certain new and useful Improvements in Pencil Attachments; 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 make and use the same.
This invention has for its object to provide a simple and efiicient attachment for pencils, pens and the like for illuminating the object written upon.
Another object is the provision of a simple illuminating attachment for pencils which may be inexpensively manufactured and applied to use upon practically any type of pencil.
With these and other objects in view, the invention consists in the novel construction, arrangement and formation of parts as will be hereinafter specifically described, claimed and illustrated in the accompanying draw ing, in which:
Figure 1 represents a sectional view through the attachment, illustrating a fragment of a pencil. Fig. 2 represents a side elevation of the attachment in use. Fig. 3 represents a bottom plan view of the attachment removed.
Referring to the drawing in detail, wherein similar reference numerals designate corresponding parts throughout the several views, the numeral 5 indicates the tubular.U-shaped body of the attachment which is preferably formed of hard rubber or other insulating material and is provided in the pencil-receiving end 6 thereof with an annular shoulder 7 for engaging and limiting the inward movement of a pencil 8 The bore of the end 6 is preferably tapered inwardly from the edge to the shoulder 7 to insure tight frictional engagement of the end of the pencil 8 therein to prevent loss or disengagement of the attachment. The opposite end of the body 5 is formed with internal screwthreads to receive an electric lamp 8,'one of the contacts of which is engaged by a spring contact member 9 secured in the web portion of the U-shaped body 5. The other or central contact or electrode of the lamp 8 is engaged by a relatively stationary contact 10 secured to the U-shaped member adjacent the lamp-receiving end thereof. The contact 9 is preferably formed of spring metal and is of adequate width to snugly fit between the screwthreads of the lamp 8.
The contacts 9 and 10 are connected with wires 11 and 12, respectively, which are extended outwardly of'the body 5 through an v aperture 13 and are connected with a battery or other suitable source ofelectro-motive force 14.
From the foregoing it is clearlyapparent that by'the peculiar shape of the body member 5 and the arrangement of the lamp 8.
with relation to the pencil 8, the rays of light from the lamp are directed toward the pointed end of the pencil and thus sufficiently illuminate the object written upon.
What I claim is:
1. An attachment for pencils and the like comprising a tubular U-shaped body having open ends, an internal shoulder formed adjacent one end adapted to limit the inward movement of a pencil relative thereto, illuminating means removably secured in the opposite end of said body.
2. An attachment for pencils and the like comprising a tubular U-shaped body, an internal shoulder formed adjacent one end of said body adapted to limit the inward movement of a lead pencil relative thereto, in
' electric lamp removably secured in the oppocomprising a tubular Ushaped body having open ends, internal screwthreads at one end of said body, the opposite end of said body being adapted to receive a lead pencil or the like, an electric lamp removably secured in the screwthreaded end of said body, and contacts secured in said body for engaging the electrodes of said lamp.
comprising a tubular U-shaped body hav- 4:. An attachment for pencils and the like 'ing open ends, an internal shoulder formed adjacent one end of said body adapted to limit the inward movement of a lead pencil,
.i internal screwthreads formed in the opposite end. of said body, an electric lamp removably secured in the threaded end of said body, contacts secured in said body engag ing the electrodes of said lamp, and Wires secured to said electrodes and extending eX- teriorly of said casing.
In testimony whereof I affix my signature in presence of two Witnesses.
