CLIP FORMEGHANIGAL PENCILS. 3

Application filed April 13, 19212. Serial no. 552,093. I

To all whom it may concern:

Be it known that 1, JOHN C. NAHL, a citizen'of the United States, and a resident of the city of Chicago, county of Cook, and

State of Illinois, have invented certain new and-useful Improvements in Clips for Mechanical Pencils, of which the following is aspecification.

My invention relates to improvements in devices for holding pencils in the pocket, and has'for its object to provide a cheap, simple, reliable, and desirable clip whereby a pencil may not only be held securely in the pocket but may be available at all times for instant use. 1

' Another object of my invention is to eliminate soldering, riveting, or any other means generally used to permanently aflix a clip to the pencil body. Through experience it has become recognized that the portion of the clip immediately adjacent the portion attached to the pencil barrel suflers the full strain when the prong of any resilient clip is forcibly moved away from the barrel in order that the edge of the pocket of a garment may be inserted between thepencil barrel and the prong to prevent the pencil from becoming lost, consequently thefre- 'quent fastening of the pencil to the garment in every day use weakens that part of the clip and it will eventually break. My improved clip eliminates this fault entirely.

The invention is fully disclosed in the following specification of which the accom- H panying drawings form a part.

Referring to the drawings V Fig. 1 a plan view of a mechanical pencil embodying my improved clip,

Fig. 2 is 'a view of that part of the pencil barrel in which is impressed the seat-for the cli Fig. 3 is a cross sectional view taken on the line 33 of Fig. 2,

Fig. 4 is a cross sectional view 4l4 of Fig. 2, I

5 is a plan view of the clip,

Fig. 6 is a top plan view of Fig. 5,

Fig. 7 is a sectional View along the line 77 of Fig. 5, and i Fig. 8 is a cross sectional view on the line 8-8 of Fig. 1.

In th drawings, 10 indicates a metal barv V onthe line rel of the ordinary mechanical pencil now in general use, havin a transverse incision. 11 out therein, the thickness and width of the incision being such as to receive the clip :12 hereinafter to be-descr-ibed. Clip seat 13,

of. a conformation such asshownv in Figs. 1 and 2, is formed in the barrel by embossing the barrel immediately below the incision 11, thegeneral outline of the embossing being curved inwardly to form the indentations 16; the lines then curve outwardly and come together by forming the circular shaped. por tion 17. A metal clip 12, having a prong 18 which is adapted topress against the body portion of the barrel when the clip is affixed to the pencil, is provided, said clip beingv bent to form the loop 19, the base 20 of the clip being fashioned to conform with the clip seat 13 in the pencil barrel. 7

An inner sleeve commonly used in all modern pencils, is adapted to be placed in the barrel 10. a

The manner of assembling is as follows z After the incision 11 has been cut in the barrel and the clip seat 13 stamped there- Assrenon TO THE WAHL ooivirnnY, or

in, the base 20 of the clip 12 is passed through the incision 11 until the circular portion 22 of the base engages the correspondingly shaped impression 17 in the barrel The indentations 28 of the clip base i will engage the indentations 16 of the clip seat 18 and that part of the base of the clip immediately above the indentations 23 will rest in that space formed in the clip scat immediately between the indentations l thereon and the incision 11. .When the base of the clip engages the clip seat 13 in the barrel, the forward end of the prong 18 presses against the barrel 10. It will be noted that'the clip seat 13 formed in the barrel 10is pressed out of alignment with the generalcontour of the barrela distance approximately equal to the thickness of the base 20 of the clip 12, thus causing, when the clip base 20 of the clip 12 is en-' gaged with the clip seat 13, a smooth surface of the inner wall of the barrel 10. Af-

. ter the base of the clip is positioned within the clip seat in the barrellO, the inner barrel 21 is inserted in the outer barrel 1.0, the i inner barrel being dimensioned to conform with the inner face or wall of the barrel 10, and held therein by friction engagement or permanently afiixed thereto by any ordinary means. When the inner barrelis inserted in the outer barrel 10, it looks the clip base 20 of the clip 12 inlthe clip seat, and due to the fact that the diameter of the circular end portion 22 of the clip base is. greater than the distance between the indentations 16 in the clip seat, the clip cannot become detached from the pencil.

VVhile I have illustrated and described the preferred "form of construction for carrying my invention into effect, this is capable of variation and modification without depart- -metal body provided with a transverse 1ning' from the spirit of the invention. 1, therefore, do not wish to be limited to the precise details of constructionset forth, but

desireto avail myself ofsuch variations and modifications as come within the scope of the appended claims.

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

1. In a pencil; in combination, a hollow metal body provided with atransverseincision' therein and a clip seat adjacent there to, fashioned by. outward impress of the metal body to. form a clip. seat, its longitudiand interlock in the clip seat in the metal body.

2..In a pencil, in combination, ahollow cision therein and a clip seat adjacent there to, and provlded with an outwardimpress,

itsgside portions being offset to form locking lugs, a clip, itsseating portion fashioned for entry through the incision and forconformatory seating in the clip seat in the metal body; and an interior holder member adapted 'for snug seating relation with the seating portion ofthe clip In witness whereof, Ihave hereunto subscribed my name- JOHN G. WAHL:
