2 Claims.

My invention relates to bushings and clips for mechanical pencils and has as its principal objects to simplify such constructions, to improvethe appearance thereof and to increase the ef' ficiency of the clipand minimize the damage to parts during the assembling process.

'I'he invention consists principally in a selfcontained bushing and clip assembly for mechanical pencils wherein the clip has a perforated head that ts over the bushing and the bushing has a peripheral flange for locating it and the clip at the end of the pencil. The invention further consists in the pencil bushing and clip and in the parts and combinations and arrangements of parts hereinafter described and claimed.

In the accompanying drawing.

Fig. 1 is an elevation of a mechanical pencil having a bushing and clip construction embodying my invention, showing the clip in sidev elevation;

Fig. 2 is a partial elevation of the pencil showing the clip in front elevation; y

Fig. 3 is a sectional Vview on an enlarged scale on the line 3-3 in Fig. 1 ,fthe bushing being shown in elevation;

Fig. 4 is a sectional view on an enlarged scale on the line 4-4 in Fig. 2;

Fig. 5 is a perspective view of a partly assembled bushing and clip; and

Fig. 6 is a view similar to Fig. 2 showing a modification omitting the ornamental ring shown in the other views.

In Fig. 1 is illustrated a mechanical pencil of a well-known type including a hollow body I of Celluloid or other plastic, a conical tip 2 through which the lead 3 extends, a cap 4 for the end of the body remote from the point and a clip 5 for holding the pencil in a pocket or other receptacle. 'Ihe present invention relates to the construction of said clip 5 and its associated parts.

Inserted-in the end of the pencil body is a sleeve or bushing '6 having its lower end 'I closed, so as to constitute a receptacle for spare leads 8. 'Ihe clip 5 has a transversely extending head portion- 9 in which is an opening Ill through which said bushing 6 extends. The bushing 6 is provided with a peripheral external ilange I I that is formed by crimping or otherwise.

As shown in Figs. 1 to 5 inclusive, an ornamental ring I2 is interposed between the head of the vclip and said flange, said ring being shown as having the same outside diameter as the clip ring and the bushing ange. Thus, when the assembled bushing 6, ring I2 and'clip 5 are mounted at the end of the pencil body, said flange II conternal flange II on said bushing. The bushing is ,stitutes a stop or locating means for properly `positioning the parts in the pencil body. The portion I Ia of the bushing on which said ornamental ring and said clip ring are mounted is of slightly larger diameter than the body of said bushing o so that the clip is rmly held. Said portion may be knurled to give it a iirmer grip. The short portion I3 of said bushing 6 that projects above the end of the pencil body has an internal ribI constituting a seat for an eraser I5. The Celluloid or other cap 4 is mounted on the projecting eraser holding portion of said bushing 6.

In the modification shown in Fig. 6, the ornamental ring is omitted, the head 9 of the clip 5 directly engaging the external flange II of the bushing 6.

The above described construction is quite simple and dispenses with numerous operations required with the customary clip constructions which are secured to the pencil barrel. The clip ring 9 is easily slipped over the bushing 6 (with or without an ornamental ring. above it) and moved endwise until it reaches the enlarged Aportion I IaV of the bushing and is stopped by the ex- 25 then inserted in the pencil body and forced endwise until the clip ring seats against the end of the pencil body. Said bushing is of a diameter to fit tight in said body and knurled bands I6 on the bushing 6 assist it in gripping said body so as to be firmly held in place. The gripping portion I 'I of the clip is above the level of the bottom of the bushing, thus furnishing adequate support for the clip and preventing the pencil body from being distorted due to the spring force of the clip. The above described bushing and clip constructionv may be preassembled in a separate department or, factory and the assembled bushing, clip and eraser, with or without the ornamental ring, may be easily assembled with theCelluloid or other pencil barrel. The construction is very neat in 'appearance and it dispenses with several parts and several assembling operations heretofore required in securing clips in placeon pencil bodies or caps. The ornamental ring may be made of any desired material or Celluloid or other plastic and affords a simple and durable means for improving the appearance of' the pencil.

Obviously numerous changes may be made without departing from the invention and I do not wish to be limited to the precise construction shown.

What I claim is:

fil

l. A pencil construction comprising a hollow barrel, a bushing fitting tightly therein and having a peripheral flange and al clip having a ring integral therewith fitting over said bushing between the end of said barrel and said flange. whereby said ange positions said bushing and said clip.

2. A pencil construction comprising a hollow internally cylindrical barrel, a. cylindrical bush-
