PENCIL ATTACHMENT.

Application filed. April 5, 1922.

T 0 all to 700m it may concern Be it known that I, CHARLES E. HANsEN, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented new and useful Improvements in Pencil Attachments, of which the following is a specification.

This invention relates to certain new and useful improvements in pencil attachments, and the primary object ofthe invention is to provide an attachment that can be easily and quickly engagedover the end of the pencil and which has spring means asso ciated therewith for attachment to the garment of the user, so as t'ojallow the pencil to be moved away from the garment for convenient use in writing, and which when not in use for writing holds the pencil close to the garment and to the attaching means on the garment.

A further object of the invention is to provide an attachment of this type which has means for completely housing the spring when the pencil is not in use, and for also permitting ready access to the spring conneoting means, if desired or found necessary.

A still further object of the invention is to provide a device of this kind which is of simple and economical construction and wherein the parts are frictionally united, thus dispensing with the use of solder or other separate fastening means.

The invention has further and other objeots which will be later set forth and manifested in the course of the following description.

In the drawings:

Figure 1 is a side elevation showing the spring expanded, and

Figure 2 is a longitudinal sectional view with the spring in contracted and housed position.

In proceeding in accordance with the pres ent invention, a cap 1 is employed which has a closed outer end 2 formed with a struckup ring 3 to which the inner end of a coil spring 1 is secured by means of a suitable hook or the like as indicated at 5. The cap 1 frictionally engages over the pencil P and has a peripheral bead 6 rolled out therefrom and located in spaced relation to the closed end 2. A sleeve 7 is employed which has its ends 8 and 9 rolled outwardly to form finishv Specification of Letters Patent.

ing-beads, the bead. 9 acting to engage the bead 6 of cap 1 so as to restrict movement of the, inner end of the sleeve 7 over the outer end of the cap 1. The sleeve 7 has a tight frictional fit over the cap 1 so that by. eXert- -1ng some little force, the two parts can be separated to gain access to the connectionof the spring 4 to the ring 3 of the cap 1. The spring 4: is very flexible and light, and has ts outer end connected to a safety pin 10 or other fastening, which latter is attached to the garment G of the user. The spring f is of a diameter so as tobe housed within the sleeve 7 when the pencil is released from the hand of the writer or user. Thus inFigure 1 it will be noted that the pencil is in the position in which the major part of the coil spring is out of the sleeve 7, in which position the pencil can be used for writing. Upon release, the spring contracts and its convolutions enter the sleeve 7 as depicted in Figure 1, so as to be housed by the sleeve. If desired the convolutions of the spring adjacent to the pin or fastening 10 can be made so as to frictionally engage against the inner circumferential wall of the outer end of the sleeve so as to assure the spring maintaming its housed position. This might be found necessary in the case of a very light spring and a pencil of such weight as to tend to accidentally move the parts to the posi tion of Figure 1.

From the foregoing it will be seen that no solder or other fastening means is required for the various parts, and the entire invention can be cheaply produced and frictionally fitted over a pencil.

IIaving thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a pencil attachment, a cap having a closed end with a struck-out ring and having a bead intermediate its ends, said cap being 2. In a pencil attachment, a cap formed for frictional engagement over the outer end of the pencil, a sleeve connected to the cap and having an open outer end, a coil spring formed to be housed within the sleeve and having one end connected to the cap, and a fastening connected to the outer end of the spring for securement to the garment of the user.

3. In a pencil attachment, a sleeve having one end formed to receive an end of a pencil therein and having its opposite end open and extending beyond said end of a pencil, a coil spring of a diameter to have its coils received and housed in said opposite end of the sleeve, means to secure the inner end of the spring in position within the sleeve, and

. means to secure the opposite end of the spring to a garment, said opposite end of the spring being disposed without the sleeve when in extended position.

4. In a pencil attachment, a cap formed for frictional engagement over the end of the pencil, a fastening for attachment to the garment of the user, a coil spring connected to the cap and to the fastener and in operative position extending outwardly of and beyond the cap to allow the pencil to be used for writing while connected to the garment, and housing means for the spring carried by the cap and extending longitudinally of the pencil.

5. In a pencil attachment, a coil spring, means to connect the spring to the garment of the user, means to secure the spring to a pencil to allow the spring to extend and the pencil to be used for writing while connected to the garment, and housing means for the spring to receive the latter when the spring is contracted.

6. In a pencil attachment, hollow means formed for engagement over the end of a pencil, a coil spring formed for housing within the said means and connected to the same and means for fastening the spring to the garment of the user, the major part of the spring being movable into and out of the first means to allow the pencil to be used for writing while connected to the garment.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
