WRI TI NG TMPLEMENT Filed Dec. 24, 1934 INVENTOR Patented Jan. 17, 1939 UNITED STATES PATENT FFICE WRITING IMPLEMENT Arthur Pestel, NeWYcrk, N. Y. Application December 24, 1934, Serial No. '758,880

8 Claims. (CI. 120--9) This invention relates to writing implements and especially to mechanical propel pencils. In carrying a proper pencil on a person's body, the practice prevails to carry the same in the pocket on a clip with the point of the pencil directed downward. While this practice of carrying a pencil is generally recognized as the most convenient, it nevertheless is known to possess certain disadvantages and even dangers to a wearer,

in that the pointed pencil may hurt a person when falling or when being pressed against.

It is for these and other reasons that many prefer not to carry a pointed pencil in their pocket and are satisfied to go without this convenience.

While many common non-propelling pencils are known to be provided with a pencil point protector, it has not however been possible to develop a mechanical propel pencil of which its pointed end can be protected without however being unwieldy in its practical application and/or unsightly in its generally graceful appearance.

It is therefore one of the main objects of my invention to provide a propel pencil of which its pointed end can be concealed.

It is another object to provide a propel pencil which is concealable in a holder.

It is a further object to provide a concealable propel pencil, which will retain spare pencil parts within its casing.

It is another object to provide novel means for extracting the spare pencil parts from the concealable propel pencil.

These and other objects which will be pointed out in the specification and especially the claims,

I attain by means of the devices illustrated in the accompanying drawing, in which:

Fig. 1 is a side view of an invertible propel pencil of oblong cross section in a position for use. i

4.0 Fig. 2 is a side View of the pencil shown in Fig. 1, with the propel pencil in an inverted or inoperative position.

Fig. 3 is an enlarged sectional plan view of the greater part of the pencil shown in Fig. 1.

4.5 Fig. li is a Sectional side view of the invertible pencil unit on line -ll Fig. 3.

Fig. 5 is a cross section of the pencil, showing a plan view on line 5-5 Fig. 3.

Fig. 6 is a bottom view of the closing cap of the l50 pencil unit, on line 6--6 Fig. 4.

Fig. '7 is a top view of the end part of the pencil unit, with the closing cap displaced.

Referring to Figs. 1, 2, 3, 4, 5, 6 and 7, a propel pencil unit ill held in a tubular holder ll, is 55 removable therefrom and may be placed in an lpart of casing ili.

either operative or non-operative position as shown respectively in Figs. l and 2.

The propel pencil unit lil comprises a propel mechanism 2 of a conventional design, tightly held by its stationary pivot member is in an end The latter is slidable within holder i i. The casing and holder are preferably oblcng or elliptical in cross section. Casing ili is curved from its largest dimensioned points towards the pivot member EB which has a Circular contour, so as to provide a good gripping surface for this member and a pleasing design of the casing as well.

The other end part of casing Id is provided with a closure device lil, serving the purpose to permit an extraction of spare pencil inserts ll, which are held in this casing. This closure device comprises a closure cap iti which has a stud iQ at its bottom surface and the middle section thereof. The closure end part of casing lil is provided with a bridge piece having a guide hole in its center to locatethe stud IQ and closure cap ES on this end part. A spring 2l located on this stud, between the lower surface of the bridge and a washer 22 held at the end part of this' stud, serves the purpose to press the cap against the casing.

Ordinarily the cap is in line with the casing to prevent a pencil insert from escaping. If however a spare pencil insert is required, the cap may be turned substantially 90 degrees, Fig. '7, so that the narrow sides of the oblong cap leave two openings at the end of the casing through either of which one or more pencil inserts may be extracted.

In order to positively locate the cap on the casing in a closed condition, a protrusion 23 has been provided on the lower surface of the cap, which protrusion is ordinarily seated in a detent 2d on bridge 2% by means of the pressure spring 2l.

Pencil unit lil is positively located in holder ll in a lengthwise direction by means of a stop member 25, which may be of tubular form as shown or any other suitable design.

The invertible pencil described is mainly for the purpose of carrying it loose in a vest pocket or the like. It is especially useful in that it can not tear the inside of a pocket and still possesses all the advantages of a mechanical propel pencil.

While the invention discloses the preferred form in which the same is to be applied, it is to be understood that various changes relative to the shape, size, material and arrangements of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

Having described my invention, What I claim is:

1. A writing implement comprising a casing for a pencil mechanism, said casing having an oblong cross section Whereby to provide a housing part With a cross-dimension of comparatively small magnitude for gripping the casing When writing, and a cross-dimension of larger magnitude to increase the capacity to store pencil spares.

2. A Writing implement comprising a casing for a pencil mechanism, said casing having an oblong cross section whereby to provide a housing part With a cross-dimension of comparatively small magnitude for gripping the casing When writing, and a cross-dimension of larger magnitude to increase the capacity to store pencil spares, one end of said casing having a conical contour.

3. A Writing implement comprising a casing for a pencil mechanism, said casing having an oblong cross section Whereby to provide a housing part with a cross-dimension of comparatively small magnitude for gripping the casing When writing, and a cross-dimension of larger magnitude to increase the capacity to store pencil spares, one end of said casing having a conical contour and the other end thereof being adapted to house a closure for the aperture of said casing.

4. A writing implement comprising a casing for a pencil mechanism, said casing having an oblong cross section whereby to provide a housing part With a cross-dimension of comparatively small magnitude for gripping the casing when writing, and a cross-dimension of larger magnitude to increase the capacity to store pencil spares, one end of said casing having a conical contour and an aperture adapted for maintaining a pencil mechanism.

5. A writing implement comprising a casing for a pencil mechanism, said casing having an oblong cross section Whereby to provide a housing part with a cross-dimension of comparatively small magnitude for gripping the casing When Writing, and a cross-dimension -of larger magnitude to increase the capacity to store pencil spares, one end of said casing having a conical contour, the conical angle of which is substantially the same as that of the protruding operating tip of a pencil mechanism.

6. A Writing implement comprising a casing for a pencil mechanism, said casing having an oblong cross section whereby to provide a'housing part with a cross-dimension of comparatively small magnitude for gripping the casing When Writing, and a cross-dimension of larger magnitude to increase the capacity to store pencil spares, one end of said casing having a conical contour and the other end thereof being adapted to maintain a shiftable closure for the aperture of said casing.

'7. A Writing implement comprising a casing for a pencil mechanism, said casing having an oblong cross section whereby to provide a housing part with a cross-dimension of comparatively small magnitude for gripping the casing when Writing, and a cross-dimension of larger magnitude tok,

increase the capacity to store pencil spares, one end of said casing having means to maintain a rotatable closure for the aperture of said casing.

8. A Writing implement comprising a casing for a pencil mechanism, said casing having an oblong cross section whereby to provide a housing part with a cross-dimension of comparatively small magnitude for gripping the casing when Writing, and a cross-dimension of larger magnitude to increase the capacity to store pencil spares, one end of said casing having a conical contour, the conical angle of Which is substantially the same as that of the protruding operating tip of a pencil mechanism, the other end of said casing being adapted to maintain an opera-m ble closure for extracting stored pencil spares from said casing.
