PENCIL.

SPECIFICATION forming part of Letters Patent No. 480,188, dated August 2, 1892.

Application filed March 17, 1892. Serial No. 425,343- (No model.)

To all whom it may concern.-

Be it known that I, ALFRED Fonnnnnnaa subject of the King of Sweden, and a resident of New'York city, in the county and State of New York, have invented new and useful Improvements in Lead, Crayon, Slate, and other Pencils, of which the following is a specification.

My invention is essentially a contrivance whereby sharp points of the lead, crayon, or

tudinal section of a portion of the pencil,

showing the manner of discharging a worn or broken point.

The general principle of the invention consists of the leads or other markers a made in short taper pieces, a magazine-tube b, containing a number of such markers, and means for displacing a broken or worn point and substituting a new one through the instrumentality of a movable device, as a push-piece c, to be worked with a finger by the person holding the pencil, and the taper point is pressed and held firmly in the taper nose d of the holder by a spring 6, the said means for displacing the worn or broken point being in this example of my invention a slot f in the side of the magazine-tube back of the taper point and the cover g thereto, along which the magazine is moved to uncover said slot by pressure of the finger on the push-piece and permit the worn or broken point to drop out when pressed back out of the taper nose by hand over the slot, the pencil being then first turned point upward, so that the points in the magazine will drop away from the slot and then held horizontally or thereabout with the slot in the under side, as in Fig. 3. The

cover of the slot is in this example a flat strip attached to the lower end of ahandle-tube h,

in closing the magazine-tube, so that one slides relatively to the other for covering and uncovering the slot. The movement in the direction for covering the slot is caused by the aforesaid spring a, which is coiled around the magazine-tube within suitable space provided for it between said tube and the handle-tube and is seated on the inside of the lower end of the holding-tube, which is shorter than the magazine-tube, and bears on the shoulder j of the latter near but a suitable distance within the upper end of the handle-tube. The new point is substituted by holding the pencilpoint downward sutficiently to permit the next point in the magazineto slide into position in the nose, and it is then secured there in by its upper end being pressed against the lower end of the cover, which when the pressure is removed from the push-piece and. the spring is released projects inward over the upper end of the point and bears thereon subject to the pressure of the spring. The said lower end of the cover springsinward through the slot and over the end of the point when its inwardly-bent portion 7a passes over the ledge Z at the upper end of the slot, said bent portion being provided to force the lower end outward as the cover is drawn back and leave free passage for the points along said lower end.

It will be seen that with the magazines thus charged with sharpened points a new sharp point is always ready when required and the Waste of time and labor of sharpening worn or broken points is wholly avoided.

I claim 1. In a pencil, anumberof individual marking-points, amagazine containing said points, a push-piece, and means adapted to be actuated thereby to renew the points, substantially as described.

2. The combination, in a pencil, of a magazine containing a number of individual marking-points, a point-holding nose, a pusher adapted to hold the points in said nose individually, and means for discharging the worn or broken points out of said point-holding nose below or in advance of the points in reserve in the magazine, substantially as described.

3. The combination, in a pencil, of amagazine containinganumber of individual marking-points, a point-holding nose, a pusher adapted to hold the points in said nose individually, and means for discharging the worn or broken points backward out of said pointholding nose below or in advance of the points in reserve in the magazine, substantially as described.

4. The combination,in a pencil, of a magazine containinga number of individual marking-points, a point-holding nose, a pusher adapted to hold the points in said nose individually,a discharge-opening for the Worn or broken points through the side of the magazine above or back of the point-holding nose, and an adjustable cover for said opening, substantially as described.

5. The combination, in a pencil, of a magazine containing a numberof individual marking-points, a point-holding nose, a pusher adapted to hold the points in said nose individually, a discharge-opening for the Worn or broken points through the side of the magazine above or back of the point-holding nose, and a cover for said opening consisting of the point-holding pusher, substantially as described.

6. The combination, in a pencil, of a magazine containing a number of individual marking-points, a point-holding nose, a pusher adapted to hold the points in said nose individually, a tube inclosing the magazine and having the pusher attached, said tube and magazine movable lengthwise relatively to each other, and aspring-aetuatin g the pusher, substantially as described.

7. The combination, in a pencil, of a magazine containing a numberof individual marking-points, a point-holding nose, a pusher adapted to hold the points in said nose individually,a discharge-opening for the worn or broken points through the side of the magazine above or back of the point-holding nose, a tube inclosing the magazine and having the pusher attached, said tube and magazine movable lengthwise relatively to each other, and a spring actuating the pusher, substantially as described.

8. The combination, in a pencil, of a magazine containing a number of individual marking-points, a point-holding nose, a dischargeopening through the side of the magazine above or back of the point-holding nose, the spring point-pusher, and discharge-opening cover, the tube inclosing the magazine and having the pusher attached, said tube and magazine movable lengthwise relatively to each other, and the ledge of the dischargeopening adapted to effect the lateral movement of the pusher, substantially as described.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two Witnesses,this 12th day of March,

ALFRED FORNANDER. \Vitnesses:
