LEAD, CRAYON, OR OTHER HOLDER.

SPECIFICATION forming part of Letters Patent N0. 499,191, dated June l6, 1893.

I Application led July Z8, 1892. n Serial No. 441,434. (No model.)

To a/ZZ whom it may concern.-

Be it known that I, ALFRED FORNANDER,a subject of the King of Sweden and Norway, and a resident of New York city, .in the county and State of New York, have invented certain newand usefullmprovementsinLead,Crayon,

' ings in which- Figure 1, is a sectional elevation of my improved pencil asl prefer to make it, with the point in position for use. Fig. 2, is a like section of the lower part of the pencil with the parts in the positions showing the manner of substituting a new point. Figs. 3 and 4 are sectional elevations; of like pencils in which some of the parts are modified to some extent but are adapted to operate on the same general principle. Fig. 5, is a like section of the lower part of the form represented in Fig. 4, with the parts in the position for substituting a new point.

The essential principle of the invention consists of a series of short taper points of lead or other marking substance contained in a magazine having a split contracting nozzle at the lower end, and contained in a case or handle tube at the lower end of which is a taper nozzle adapted to receive the points through the split nozzle, and hold them` by the head with the most of the length projecting :for use, said points being larger in the head than the bore of the said taper nozzle and being pressed downward and confined therein by pressure of the end ot' the-split nozzle against the upper ends of the heads, the said split nozzle being pressed down and contracted in the .taper nozzle over the heads and caused to press downward -thereon and hold the points iirmly in the position for use.

I represent three dierent arrangements of apparatus in the drawings all operating upon this principle though diering somewhat in details of construction, but alike included in the claims. v

' In all the figures a, represents the case or handle tube which maybe of wood or other suitable material and of considerable thickness as in Figs. l, 2 and 3, or of'thin sheet metal like the form representedv in Figs. 4 and 5. -A

b represents the magazine tube which will preferably be of thin sheet metal.

The magazine is charged with a seriesof short taper lead, crayon or other points c, which lie one above another with the points downward.

Atthe lower end of the pencil is a taper nozzle d, for holding the points, said nozzle being detachably connected'as by screwing on the shoulder e of the magazine tube, or it may be on to the lower end of the case or handle tube, or it may be formed on the end l'of the handle tube as d Fig. 4, or of an intermediate .tube f, Fig. 3. The opening through the lower extremity of this nozzle is slightly smallerfin diameter than the heads of the points so that the points may beheldfor'use by pressure against the upper ends. To effect this pressure the lower portion g of the magazine tube has a number oflongitudinal slits extending a suitable distance upward to allow it to be contracted at the lower extremity within the area of the head of the point below and it is made to bear thereon. In Figs. 1 and 2 the nozzle clbeing first slacked oit to allow the slitted part g to expand and permit the point to drop through vinto the lower end` of the said nozzle, and then being screwed up again, so contracts the saidV part g, over the point, and it also carries the point against the contracted end and effects the required pressure. i

this case forced down by pressure of the finger on the push piece k to permit the part g to expand and allow the point to drop through. The handle tube a, and magazine tube b are connected by studs a', through slots a2 of the intermediate tube.

roo",

In Fig. 4 the like spring Z, in the space between tubes a and b at the upper end and confined between shoulder m of tube a, and the studs n, connecting ring o and tube l), through slots p of tube ct presses the expansible part g of the magazine tube down into the taper nozzle d to secure the point.

To raise the magazine tube and allow the point to drop through part g into the nozzle the ring o is held between the fingers while ther push piece k is pressed downwardly by another linger.` The worn points are discharged out ofthe nozzle d by screwing it oit,

and thrusting the points backward out of the y larger end. The points may however be wrenched out through the small end by taking the protruding portion between the edge of a knife blade or other like instrument and the thumb and giving a suicient lateral thrust to break oft the edge of the head, and this is the way the points will be discharged from the modified form of Figs. 3 and 4. The nozzles d, cl', may however be split so as to open slightly by the wrenching action on the points to facilitate the discharge.

The points may be charged into the magazine tube through the upper end or in any approved way.

The invention is thus distinguished from those in which the leads of usual length for continuous use slide freely through the nozzle of the holder, and jaws are made to grip the sides of the lead by being pressed into the nozzle for holding them which, it will be seen would not serve for short points such as are to be thrown away when worn blunt.

The invention is distinguished from that of my Patent No.l 480,188 in that the device for pressing the points down in the holding nozzle is a split nozzle formed on and being part of the inclosedmagazine tube, and the holding nozzle is exterior thereto which is a simpler and neater device.

I claim- 1. In a pencil a number of individual taper marking points, a magazine containing said points and having a split contracting and expanding lower end portion, an internally taper bored point holding nozzle exterior to the split portion of the magazine tube, the bore of said taper nozzle being continuous through its length and at the outer extremity smaller than the heads of the points, and means to press the split end of the magazine tube on the heads of the points and hold them in the taper nozzle substantially as described.` 2. In a pencil a number of individual taperI marking points, a magazine containing said points, and having a split contracting and expanding lower end portion, an internally taper bored point-holding nozzle exterior to the split portion of the magazine tube, the bore of said taper nozzle being continuous through its length and at the outer extremity smaller than the heads of the points, andv said taper nozzle being adjustable lengthwise of the split portion of the magazine tube to secure the points, and also detachable for discharging the worn points substantially as described.

Signed at New York city, in the county and State of New York, this 23d day of July, A. D. 1892.

ALFRED FORNANDER.
