9 Claims. (Ci. 120-14) My invention relates to improvements in polyons l3 are of segmental'or sector-like cross-secpointed Or multiple lead pencils and crayons and tion so that when arranged with their sharp the main object is to provide in simple, attractive edges or apices [4 turned inward together they and inexpensive form a pencil having a number form a mutually supporting cable-like assembly of leads or crayons of diifering colors or grades 5 of such exterior diameter and shape as to just and any of which may be projected from the nicely slide in and friction-ally engage the inner pencil and exposed for writing or drawing while periphery of the barrel The inner longitudithose not in use remain concealed and protected nal edges of the leads or crayons are located at from breakage. the longitudinal axis of the barrel.

Inside the barrel It a plurality of radially which a number of segmental leads or crayons spaced inwardly projecting longitudinal guide may be slidably inserted, the said barrel having ribs or beads it are formed and occur between inner longitudinal dividing ribs or beads between 15 each lead 'I S-and the next whereby these leads the leads and having longitudinal slots regisare separated slightly to permit free longitudinal tering with the leads through which slots an movement of any one without disturbing the ear on a sliding band on the barrel may be enothers. gaged with any of the leads for projecting the The barrel it also has a number of longitusame outward from the barrel at one end, dinal radially spaced slots l'l occurring in regthe said band being substantially'larger in di istry with the leads I3- as they are placed in the ameter than the barrel and the barrel near barrel, the said slots terminating short of each the working or lower end having outwardly pr'oend of the barrel a indicated at it.

The utility of such a pencil will at once be apof thin metal or other suitable material and parent, affording as it does a conveniently and closed at one end by a screw cap or other suitable selectively used assortment of leads or crayons device H and open at its other, and as hereinor different colors or degrees. The pencil is furafter termed, working end l2. The leads or craythermore inexpensive in manufacture, simple and attractive in appearthe leads when the sleeve is slid over the barrel. The sleeve 20b has threads 23 adjacent its end over the working end of the pencil and a cap 24 is threaded thereon to protect the end of the pencil. This cap 24 has a conventional clip 25 for carrying the pencil in the pocket.

In the claims, the word crayon is intended to include a stick of marking material of a composition including graphite, such as is used for pencil leads. The term includes all colored compositions which are used to make visible marks or streaks on suitable surfaces.

I claim: 1. In a pencil, a barrel, a plurality of segmental leads slidably mounted in and filling the bar,

rel, and from the barrel independently of the others.

2. In a pencil, a. barrel, 9,

sector-like cross section slidably mounted in and filling the interior of the barrel,

selecting and projecting any lead from the barrel. 3. In a pencil, a barrel, a plurality of leads of longitudinally extended slots registering with the leads, and means mounted on the barrel for engagement with the leads through the slots i'or threaded on the sleeve enclosing the end of the barrel.

4. In a pencil, a barrel, a sector-like cross section slidably mounted in and end of the barrel.

tudinally extending slots registering with the outer sides of the leads, an annular band loosely and slidably mounted around the barrel, and a laterally proJecting ear 0n the band adapted to engage a lead through one of the said slots whereby any one of the leads may be pendently of the others.

7. In a pencil, a cylindrical hollow barrel, and a plurality of. segmental crayons slidably mountprojecting any of said crayons from the barrel independently of the others.

crayons from the barrel independently of the others.
