MAGAZINE LEAD-PENCIL.

SPECIFIQATION forming part of Letters Patent No. 48 dated January 3, I893.

' Application ma Hny16.1892. Serial 1%. mass. on model.

To all whom it may concern:

'Be it known that 1, James B. SMITH, a citizen of the United States, residingat Brooklyn, in the countyof Kings and State of New York, have invented certain new and useful Improvements in Magazine Lead-Pencils; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in the art to which it apl0 pertains to make and use the same, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon, which form a part of this specification.. My invention relates to pencils, and its object is to enable one to write in morethan one color, or with leads of different degrees of hardness, with the same pencil case, so that one instrument may take the place of several.

The invention consists in a case containing. two or more lead holders, and provided with means for propelling any desired holder.

In the drawings, Figure 1 is a side elevation of the pencil closed. Fig.2 shows a lead holder projected. Fig.3isa longitudinal central section, and Fig. 4 is a cross section, on the line 4-4 Fig. 1.

The pencil case is composed of a barrel A, preferably cylindrical and having at oneend a tip B, which is secured to the barrel by a slip' joint or screw thread and contains a ccn-.

tral hole I). Secnrcdwithin the tip is a funnel C, the inner end of which is of adiameter to slide stiffly in the barrel A.

Near the upper end of the barrel is a partition a, and the endof the barrel is closed by a screw cap A, the chamber .r forming a convenient'receptacle for extra leads. Adjacent to the screw cap a collar D is formed on 0 or secured to the barrel;

similarly arranged asuitable distance above the tip B. Between the collars is a sleeve or jacket F which fits the barrel nicely and is readily revoluble thereon.

i5 In the barrel A, between the collarsD E are made several longitudinal slots (1', correspending in number with the leads it is pro posed to use. The jacket contains a single slot f, which can be made to register with any Another collarE is d ird slot a by turning the jacket. on the barreh Th lead holders G,which may be of an y usual or d ired construction, are each provided with an extension or tail g composed preferibl of a flat spring, carrying atitsupperend vented from slipping down into the funnel C.

But when the slotf of the jacket is made to i ide with a slot a, the pin is released from the groove, since the slot f intersects th groove, as shown. The lead holder thus el ed can he pushed out of the tip B, by sliding the pin 9' down the slots a'f. To accompllsh i readily, a loose collar or slide II i provided, moving freely on the jacket, and provided with an internal block h projecting into the slotfand having a notch or r adapted to engage a pin g. \Vhen the ll r ii is at the upper end of the jacket as shown in Fig. I, the notch in the block it coi id g with the groovef in the jacket, so that when the jacket is turned it carries the bl k over the pins g in succession until the desired one is reached. The slide is then moved downward, carrying the pin with it, A

containing triangular spots of color e e' e, c

corresponding with the respective colors of the leads, For instance, when our leads are e yshown in the drawings, they may be colored NSPBCU BIY, black, red, green, and blue. The spots may consist of' enamel let 5 into shallow depressions. The advan'tagcs f such a device are so apparent, that they need not boespecially mentioned.

While I am aware that the idea of a magazine pencil is not broadly new, yet I believe that the means I employ are. novel, and far more simple and reliable than those heretofore proposed.

Having thus described my invention, what I claim and desire to secure by Letters Patcut is:'

1. A magazine pencil, comprising a tubular barrel, two or more lead holders inclosed therein, and mean 5, substantially as described, for selecting and propelling any one of said holders, as and for the purpose set forth.

2. A magazine pencil, comprising a tubular barrel, having longitudinal slots, two or more lead holders inclosed in said barrel, each having a pin projecting through one of said slots, and a slide for engaging anyone of said pins and propelling the holder from the barrel, substantially as described. 1 l

3. A magazine pencil comprisinga tubular barrel, having longitudinal slots, two or more lead-holders inclosed in said barrel and having pins projecting through said slots,a slide adapted to engage anyone ofsaid pins and propel the holder from the barrel,and means 7 for locking the remaining holders in place in the barrel, substantially as described.

4. A magazine pencil, comprising a tubular barrel, having longitudinal slots, two or more lead-holders inclosed in said barrel,and having pins projecting through said slots, and a jacket revoluble on said barrel and containing a single longitudinal slot, and having an annulargroove near one end to receive the pins, substantially as described.

5. A magazine pencil, comprising a tubular barrel, having longitudinal slots, two or more leadhohlers inclosed in said barrel, and having pins projectiugth rough said slots, ajacket revoluble on the barrel and having a single longitudinal slot, and a collar sliding on the jacket and carrying a block entering the slot in the jacket and adapted to engage with the pin on a lead holder, substantially as described.

6. In a magizine pencil, the combination with the tubular barrel having longitudinal slots, of the lead-holders each having a spring extension carrying a pin engaging with one of said slots, substantially as described.

7. The combination with the barrel A having the slots a, of the lead-holders G having the flat springs g carrying the pins g' entering said slots, substantially as described.

8. The combination with the barrel A, of the funnel C at one end, lead-holders G inclosed in said barrel, and means for propelling any one of them through the funnel, substantially as described.

.9. A magazine pencil containing two or more lead holders, means for propelling any one of said holders, and a guide for selecting the proper holder,substantiallyas described.

10. The combination with the barrel A containing the lead-holders G, and provided with the slots a, of the jacket F revoluble on the barrel and containing a single slot, and a collar E bearing devices in line with the slots a to indicate the characters of the several leads, substantially as described.

In testimony whereof I afiix my signature in presence of two witnesses.
