PENCIL-HOLDER.

SPECIFICATION forming part of Letters Patent No. 498,442, dated May 30, 1893. Application filed February 17, 1893. Serial No. 462,719- (No model.)

To aZZ whom it may concern: I

Be it known that I, JUMATsU MATSUO, a citizen of Japan, residing at Philadelphia, in

- the county of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Pencil-Holders; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in pencil-holders.

The primary object of my invention is to produce an instrumentwhich will enable short lead-pencils to be used. It has been customary heretofore, when a lead-pencil has been used to within a short distance of the end, to throw away this short remnant and make use of an entirely new pencil. This has arisen from the fact that it is inconvenient to hold such small piece of lead-pencil, and all the holders of which I have any knowledge have been so inconvenient and ill adapted for use thatthey have not been generally adopted.

My invention consists of certain improvements which will first be described in connection with the accompanying drawings, and

then pointed out in the claims.

In the drawings, Figure 1 is a side-elevation of the pencil-holder complete with the pencil inplace. Fig. 2 is central longitudinal section ofthe same. Fig. 3 is aside-elevation of the holder without the clamping-sheath. Fig. 4 is a side-elevation of the clamping-sheath alone. Fig. 5 is an end view of Fig. 1.

Referring to the drawings, A is a holder, preferably hexagonal in cross-section, in order to adapt it for nsein holding the ordinary hexagonal pencil, a short piece of which is shown at B. The holder A is of a diameter exceeding that of the pencil B, excepting at the extreme end a. From a to 1, it will be noticed, the inner surface of the holder is fiattened, and from 1 to 2, it tapers gradually as shown. A longitudinal slot 3 is cut from the point 2 to the end a on the two opposite sides of the holder as will be seen in Fig. 3.

O is a clamping-sheath, also tapered and flattened at one end to fit on the outside of the holder. The tapered portion extends from 4 to 5, while the flattened portion extends from 4 to c. The sheath 0 is extended being the point only of the pencil projecting beyond the end a of the holder. The clampingsheath 0 is then slipped onto the holder A and by means of the finger-hold 6, drawn upward until the flat portion from a to 1 is crowded tightly against the pencil, thus firmly holding along the entire length of said fiat portion and preventing all slippingor canting of the pencil in the holder.

It .will be noticed that the friction of the sheath on the holder is relied upon to clamp the pencil, and in order to insure .the retention of the sheath in position on the holder the inner recess 7 is provided. As the sheath is being drawn onto the holder, the latter is compressed by the fingers holding it above the" tapered portion; when the fingers release the holder at that point, the elasticity of the metal, of which the holder is constructed, tends to force the holder outward against the inner surface of the sheath, thus to a limited extent crowding into the recess 7 and holding the sheath against accidental withdrawal. The sharp corners 8 tend to cutinto the metal of the holder and also aid in retaining the sheath in place; moreover, by extending the sheath up onto the straight portion of the holder, as described, a firm hold is given for the recess 7 and corners 8 which would not be the case if the tapered portion of the holder, or of the sheath, or of both, extended all the way.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is

1. The combinatioinwith a tubular holder having a straight interior holding-portion, a tapered portion above the holding portion, and a pair of longitudinal slots, said slots being in opposite sides of the holder, of a tubular clamping-sheath having a straight interior portion, a taperedportion, anda finger-hold, said clampingl sheath-lbeing adapted'itofi tover the holder, substantially as described and for the purpose set forth.

2. The combination, with a compressible tubular holder, of a clam pin grsheath provided with a recess in its-inner side and sharp corners each side of the recess for engagement with the holder, substantially as described:

and for the purpose set forth.

3. The combination, with a compressible tubular holder havingastraightinteriorvholdl ing portion, a tapered portion above. the I straight portion, and a pair of'longitudinal slots, said slots being on opposite sides of the holder, of artubular elampingsheath having a straight interior portion,.a taperedv portion above the straight portion, and a finger-hold provided with a recess on its under side, said clamping-sheath fitting over the holder and the latter expanding into the recess, substantially as described and for the purpose set forth. 7

In testimony whereof I affix my signature 1n presence of two witnesses.
