SVEND SVENDSEN, OF CHICAGO, ILLINOIS.

WRITING-PENCIL.

Specification of Letters Patent.

Patented July 2, 1907.

Application filed September 26, 1906. Serial No. 336328- To all whom it may concern:

Be it known that I, SvEND SvENDsnN, a subject of the King of Norway, residing at Chicago, county of Cook, State of Illinois, have invented a certain new and useful Improvement in Writing-Pencils; and I declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference I being had to the accompanying drawings, which form a part of this specification. I

My invention relates in general to writing pencils, and more particularly to pencils the graphite or lead in which is adjustable.

The necessary sharpening of pencils as ordinarily constructed in order that they may be in condition for use is often inconvenient as a knife or other sharpening device is required. Women and children especially frequently find it diflicult to properly sharpen a pencil Pencils gradually become shorter with usage so that they can not conveniently be used after they have diminished to a certain degree. In order that these objections to the usual pencils may be avoided pencils have been made with a hollow tubushorter with usage, and which will not require a supply of lead to be kept on hand by the user.

A further object of my invention is to provide an improved pencil which will be simple in construction,

inexpensive in manufacture, and convenient in use.

My invention may be generally described as comprising a longitudinally divided casing, the parts of which are pivotally connected to permit the adjustment of the lead therein so that it will project through the point of the casing, means at one end of the casing for hinging together the parts thereof, and a band or cap removably surrounding the point of the casing to bind the parts thereof tightly around the inclosed lead.

My invention will be more fully described hereinafter with reference to the accompanying drawing in which the same is illustrated as embodied in a convenient and practical form, and in which Figure 1 is a side elevational view; Fig. 2 a sectional view on line 2-2 Fig. 1; Fig. 3 a cross-sectional view on line 33 Fig. 1 and Fig. 4 a view similar to Fig. 1 showing a modification.

Similar reference characters are used to designate similar parts in the several figures of the drawings. 7

Reference characters A and A designate the portions of a longitudinally divided casing for a pencil. The casing may be made of any suitable material, wood such as is ordinarily used in making pencils being preferably employed. The casing may be composed of any desired number of longitudinal shown for convenience.

B designates the cap preferably conical in form which surrounds the tapered end of the casing and binds the parts thereof tightly around the inclosed lead D. In order that the lead may be tightly gripped by the parts of the casing, saw-cuts a are preferably provided which give to the end of the casing a slight resiliency.

The end of the casing opposite to its point is provided with suitable means for pivotally or flexibly uniting the parts thereof. Preferably an eraser O is provided parts, two parts being on the butt end of the casing having a sleeve 0 surrounding and thereby flexibly uniting the longitudinal parts of the casing. v

The manner of using my improved pencil is as follows: When the point of the lead has worn away the cap B is removed and the two parts A and A of the casing are swung apart so that the lead may be longitudinally adjusted therein to such an extent that its end will project beyond the point of the casing. The cap B is then again placed around the point of the casing and pressed tightly thereon so'that the lead will be held against longitudinal movement with respect to the casing. The resiliency of the sleeve 0 of the eraser 0 permits the parts of the casing to be swung apart sufficiently to readily adjust the lead within the casing.

In Fig. 4 I have illustrated an embodiment of my invention in which a modified form of cap is provided for uniting the points of the parts of the casing around the lead. In leiu of the conical cap shown in Figs. 1 and 2 a band B may be employed which can be readily placed around the point of the casing owing to the resiliency produced by the saw-cuts a.

Although new leads may be inserted in the casing to replace those which may wear out, yet it is the intention and design of my invention to provide a pencil so economical in construction that it will not be necessary to supply new leads to a casing, the casing being thrown away when the original lead has been used up.

From the foregoing description it will be observed that I have invented an improved writing pencil which need not be sharpened, which will not shorten in length by usage and which is economical in construction.

Having now fully described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A pencil comprising a casing composed of separable longitudinal parts, a longitudinally adjustable lead inclosed within the casing, an eraser at one end of the easing having a sleeve surrounding and flexibly uniting the parts of the casing, and means surrounding the point of the casing and binding the parts thereof tightly around the lead so that the lead will be immovably held within the casing with its point projecting from the casing.

2. A pencil comprising a casing composed of separable longitudinal parts, a longitudinally adjustable lead in closed within the casing, a conical cap removably surrounding the points of the casing and binding the parts thereof tightly around the lead, and an eraser at'the other 10 end ofthe casing having a sleeve surrounding and flexibly uniting the parts of the casing.

In testimony whereof, I sign this specification in the presence of two witnesses.

SVEND SVENDSEN.
