PATENT OFFIC HENRY SPENGLER, OF NEW YORK, N.

PENCIL.

SPECIFICATION forming part of Letters Patent No. 764,312, dated July 5, 1904. Application filed July 21, 1903. Serial No. 166,478- (Ho model.) h

' be acted upon by the cutter and sharpened.

One embodiment of the invention is illustrated in the accompanying sh'eet ofdrawings, throughout the several views of which like numerals indicate corresponding parts.

In the drawings, Figure Us a view in elevation of a pencil constructed in accordance with my invention and showing a strip of the paper partly cut from the roll thereon. Fig. 2 is an enlarged sectional view of the point end thereof; Fig. 3 is a cross-sectional view taken on the lines S S of Fig. 1, and Fig. 4 is a similar view taken on the lines S S of Fig. 1.

Referring now to the drawings, 1 represents atube, which extends throughout the length of the pencil and is designed to receive the lead 2. I preferably employ a very small lead having a light covering of wood; but it will be understood that lead of larger diameter withoutthe wood covering may be uscd,'if desired. The pencil or lead may be secured 4 in the tube in any suitable manneras, forexample, by means of the jaws 3 3, which are actuated by the collar 4 and spring 5 to normally clamp the lead, as shown in Fig. 2.

A tubefi, inclosing the lead-tube, is enlarged at the end adjacent to the pencil-point I to receive a tubular section 7, which through the action of the spring 8 tends to telescope into the open end thereof. The .tubes 6 and 7 are connected to rotate together by means of lugs 9 9, &c., of the collar 4, which project through registering slots thereof. Threaded the tube 6 between terminal springs 13 13" and the longitudinally-disposed cutter-bars 14 14. As shown in Figs. 1 and 4,.the spring 13 is detachably secured to the cutter-bars 14 14 by buttons passing through slots thereof.

when about exhausted may be removed and replaced by a new one. The cutter-bars become adjusted to the varying diameter of the roll by the action of the springs in contracting as the paper is drawn therefrom.

From the foregoing it will be seen thatas and 7 will be rotated, and this motion imparted to the cutter 11 will cause the same to point the projecting end of the lead. This action continues until the length of-lead projecting beyond the clamp of the lead-tube is sufliciently reduced to permit the tube-section 6, as shown in Fig. 1. By adjusting the collar 4 to release the clainp-jaws the lead will feed out by gravity as the-tube 7 is drawn out against the action of the spring 8, and on releasing the collar to allow the clamp-jaws to again grip the lead the tube-section will be held as adjusted, as shown in Fig. 2. When itis desiredto point the lead without drawing paper from the roll. the cutter-cap may be given several turns, first in one direction, then in the other. When the roll becomes exhausted, another may be placed in position by removing the spring 13 and slipping the roll on the tube 6, which is roughened or otherwise formed to engage a1 id rotate with the same. Having therefore described my invention, I claimof paper mounted thereon, a cutter for pointing the pencil and means for transmitting motion from the roll to the cutter.
