MAGAZINE-PENCIL.

Specification of Letters Patent.

Patented Apr. 16, 1918.

Application filed May 12, 1917. vSerial No. 168,072.

v y To all whom t may concern:

Kings and State of New York, have invented certain new and useful Improvements `in Magazine-Pencils, of which the following is a specification, reference being had therein to the accompanying drawings, forming part thereof.

This invention is a magazine pencil designed to hold a number of pencil leads and to feed them successively through the marking end of the pencil as they arev worn down in use.

' In the accompanying drawings,

Figure 1 is a longitudinal mid-sectional view of the pencil, and l Fig. 2 is a transverse ysectional view thereof onthe plane 2, 2 of Fig. l.

A tubular magazine 3 is closed at its rear end by a button 4 and at its front end is contracted in conoidal form and prolonged into a tubular extension 5 of smaller diameter which serves as the lead holder. The leadholding tube 5 joins the reduced end of the conoid of the lead magazine so that when the encil is held with the button end up and slig tly shaken, one of the leads 6 will be guided into the lead-holdingtube 5 and will slide down through this tube until its end projects therefrom. The front end of the holding tube 5 is split as indicated at 7 and the bifurcated halves of the tube are flared away from each other so that when the tube is drawn rearward throu h the constricted end of the casing 8, the inding action'of the casing on the split holder will 'p the pencil lead in anyA desired position. A spring 9 is coiled upon the holding tube 5 and compressed between the front end of the casing and the front end of the pencil reservoir 3, so that it tends always to force the holding tube 5l rearward to grip the pencil lead at the front end of thetube. Themasing 8 extends from its constricted end 'rearwardly in expanding conoidal form until it merges into a tubular form which closely embraces the tubular magazine 3, and the rear end of this casing may be spun down as indicated at 10 to engage thishoulder formed by the overlapping of the magazine 3 on the button 4. The inward 'ange thus spun upon the casing will act as a back-stop for the expansion of the spring 9. From this description it will be apparent that when the casing is held in the hand and its button 4 is pressed, the holding tube 5 will be slid forward through the casing aperture so that its split ends may expand andvrelease'their grlp on the pencil lead which may then be adjusted to any desired position before releasing the button to regrip the lead. rlhe magazine is loaded by holding the pencil casing point upward and pressing the button to expand the end of the holding tube 5, 'after which the leads may be successively inseated, droppingl successively into the maga,- zine. l

The invention may be embodied in otherl constructions, some of which will be obvious to those skilled in the art, and others of which may be inventivel devised, all with in the spirit and princip es and scope of the invention and the following claims.

1. A pencil comprising a tubular lead magazine with a sconoidal end, a tubular lead holder projecting from said conoidal end of the magazine and having a split end,.a. cylindrical casing having a sliding fit over the magazine and having a conoidal end with an 'aperture sliding over the split end of the holder, and a spring coiled on the holder and compressedbetween the conoidal end of the magazine and the conoidal end of the casing, 4and means for sliding the magazine in the casing to compress the s ring and release the split end of the lead holder.

2. A pencil comprising a tubular lead magazine with a conoidal end, a tubular lead holder projecting from said conoidal end of the magazine and having a split end, a cylindrical casin having a sliding fitover the magazine an having a conoidal end with an aperture sliding over the split end of the holder, a, Spring coiled on the holder and compressed between the conoidal end of the magazine and the conoidal end of the holder, and a rearward projection from the magazine which projects from the rear end Laeaaae magazine and having a colloidal end with an and an inward Hange formed on the rear end aperture sliding over the split end ofv the of the casing around said button to engage holder, a spring coiled on the holder and the rearend of the magazine and act as a 10 compressed between the conoidal end of the stop for the spring.
