To all whom, t may concern.-

Be it known that I, FRANK MCINTYRE, a citizen of the United States, residing at New York, borough of Bronx, State of New York, have invented a new and useful Improvement in Pencil-Tips, of which the following is a specification.

his invention relates to metallic penciltips designed to be mounted on lead-pencils and to hold erasive material.

It consists in a certain construction of the tip, which will first be described in connecion with the accompanying drawings, forming part of this specification, and will then be more particularly pointed out in the claims. -In the'drawings, Figure 1 is a erspective view of the tip and a portion of tllie pencil to which it is ap lied. Fig. 2 is a like view of the same 'portion b and pushed along the same until it brings up against the ring or band C, the latter being knurls a and c, which constitutel shoulders T he tip as a whole is then iitted upon the end of a pencil P and is held thereon by the usual indentation or indentations i., (made by a suitable indenting-toel,) whereby not only are the thimble and barrel A united together, but the tip as a whole is made fast to the pencil.

A tip of this kind requires for its -Inaking a little more metal than the ordinary seamless one-piece tip. It is, however, readily and cheaply made, and the lessened cost of' labor, particularly where the tip is to be provided with any great degree of ornamentation or place.

the three tub ar pieces or bands which make up the tip separated from one another. Fig. 3 is a longitudinal axial section of the tip and portion of the pencil on which it is mounted. Fig. 4 is alike sectional -view of a modification.

The three parts of which the tip is eomposed, are lettered A B C, respectively, al made, preferably, of s heet metal, seamless and vin tubular form. The piece A, which constitutes the upper exposed portion and main part of the tip and which I shall for distinction sake term the barrel7 contains the erasive material a: in its upper end. Between its ends it has a circumferential knurl a, and A from this knurl to its lower end it is of smooth exterior and slightly reduced in diameter as compared with the portion above the knurl, the reduction in diameter being to enable this portion b of the barrel to receive upon it the pieces B C, which have the same diameter practically as the upper portion of tube A. The part B as represented in the drawings is a comparatively narrow seamless band. The part C, which I term for distinction sake the with a band of color differing from the -body of the tip, ofl'sets the increase in expense ol' material.

By way of illustration the drawings represent a ti i in which the part B is a plain band .of red co or, while the body of the tip on each l 4`,side of the band is of yellow gold color, these colors being represented in Fig. 1 by their apropriate conventional hatchings. The band can be most readily produced from a properly-colored tube of indeinite length, which can be expeditiouslyr into bands of desired width. f

Oi courseif two or more bands B are desired there would be a circumferentially-knurled spacing ring between adjoining bands. Such a modification is shown in section in Fig. 4, in which there are two bands B,with a knurled spacing-ring between theln. rI`hev construction in other respects is the same as already described in connection with the preceding igure.

Having described my invention and the manner in which the same is or may be earried into efi'ect, I state in conclusion that I do thimble, is a formed with a circumferential knurl c. his ring is a retainingring, the band B being held between its knnrl c and the knurl a on the barrel. `When the l tip is provided with more than one band B, l as in Fig. `4e, .then a similar retaining-ring c! led for i by the change in location is interposed bei tween adjoining bands. V tting the parts together the band or ring B is first slipped onto the ortion b of the 'i thimble E is iitted upon not limit myself strictly to the structural de-I and cheaply divided up.

held between the between which it is conmed and kept in tails hereinbefore described in illustration oi the invention, since manifestly the same can be considerably varied Without departure from the spirit ofthe invention but.

What I claim herein as new, and desire io secure by Letters Patent, is

1. In a metallic tip for lead-pencils, a barrel provided with a circumferential knurl, n knurled retaining-ring {ittingupon the barrel. and a band also litting upon the barrel and 2 y enanosV held thereon between the knurl on the barrel between the knurls on the barrel nd thm :o and retaining-ring respectively, substantially 'ble respectively. t as set forth. In testimony whereof I affix my signature 2. A metallic tip for lead-pencils consistin presence of two witnesses. 5 of a barrel having at. a point between' itsv ends a circumferential knul-l or shoulder, a FRANK MINTYRE knurled thimble fitted upon and secured to Witnesses: t l the forward portion of the barrel, and a rin -4 SAMUEL KRAUs,

' or band also fitted upon theA barrel, and hel CLAES Win. BOMAN.
