5 Claims.

My invention relates to improvements in polypointed or multiple lead pencils and crayons and lthe main object is to provide in simple, attractive and inexpensive form a pencil having a number of leads or crayons of differing colors or grades and any of which may be projected from the pencil and exposed for writing or drawing while those not in use remain concealed and protected from breakage. 10

Another object is to provide a pencil of this kind of a minimum number of Working parts Y comprising simply a tubular barrel or stock into which a number of segmental leads or crayons may be slidably inserted, the said barrel having inner longitudinal dividing ribs or beads between the leads and having longitudinal slots registering with the leads through which slots an ear on a. sliding band on the barrel may be engaged with any of the leads for projecting the same outward from the barrel at one end, the said band being substantially larger in diameter than the barrel and the barrel near the working or lower end having outwardly projecting ribs into which the band may beforced to constrict the barrel slightly on the leads and hold them in adjusted position.

With these and other objects in view the in- .vention resides in the novel construction and arrangement of parts as hereinafter fully set forth and claimed, reference being had to'the accompanying drawing wherein:

Figure 1 is a side view of my pencil.

Figure 2 is an enlarged section along the line 2 2 in Figure l.

Figure 3 is an enlarged fragmental longitudinal section showing the action of thevband in moving the leads. A

Figure 4 is an enlarged section along the line 4 4 in Figure 1.

Figure 5 is a side of one of the leads or crayons alone. Figure 6 is a side view ended form of my pencil.

Figure '7 is a side view, partially in section of a modified enclosed form of pencil.

Figure8 is a fragmental longitudinal section through the pencil of Figure 7 showing the action of the sleeve in moving one of the leads.

Referring now with more particularity to the drawing my invention as shown in Figures 1 to 5 comprises an elongated tubular barrel or body II) of thin metal or other suitable material `and closed at one end by-a screw cap or other suitable device II and open at its other, and as hereinafter termed, working end I2. The leads or crayons of a modified doublethe ribs I3 are ofl segmental or sector-like cross-section so that when arranged with their sharp edges or apics 'I4 turned inward together they form a mutually supporting cable-like assembly' of such exterior diameter and shape as to just nicely slide in and frictionallyengage the inner periphery of the barrel I0. At their intended Working ends the leads I3 are sharpened or tapered olf toward theapi'ces .I4 as indicated at I5. Inside the b arrel I0 apluralityof radially'spaced inwardly projecting longitudinal guide ribs or beads I B are formed and occur between each lead-- I3 and the next whereby these leadsfare separated slightly" to permit free longitudinal movement of any one without disturbing the others.

'I'he barrel I0 also has a number of longitudinal radially spaced slots-Isl occurring in registry with the leads I3 as they `aralplaced in the barrel, the

said slots terminating short of each end of the barrel as indicated at I1 and vat the working end I2 of the barrel outwardly projecting pressure ribs I9 are formed and extend inwardly along the barrel past the adjacent ends I8 of the slots' as shown. An annular sliding band 20 of somewhat greater diameter than the b arrel I0 is slidably mounted thereon and has a laterally projecting ear or linger 2| serrated onits under or inner side as at 22.

In use, any one of the sharpened ends I5 of the leads I3 may be` projected out from the worklead may be moved by sliding the band along the ban'el. I'he leads may -then be -secured -in ad- J'usted position by sliding the band 20 down over I9 which have a. projection calculated to bring' an inward compression or constriction on the barrel when the band 20 is forced over the ribs. SufIicient resiliency in the barrel I0 is provided for its constriction in this manner both by the thinness of its Walls and the slots I'I which extend between the ribs I9 as set forth.

'I'he utility of such a pencil will atonce heapparent'affording as" it doesV a conveniently and' selectively used assortment .of leads or crayons of different colrs` or degrees. 'I'he pencil is furthermore inexpensive in manufacture, simple and convenient in use and attractive in appearance.

I8. Intermediate the slots In Figure 6, a double ended pencil is shown J wherein all the foregoing parts are duplicated at each end of the barrel Illa, the slots Ila andribs I9a being provided 'at each end of the barrel with 2 separate bands 20a for moving and manipulating a diierent and separate set of leads I3a at each end as shown. The color range or capacity of the 'pencilis thus doubled by this arrangement as will be understood. i

In Figures 7 land 8 an enclosed form of the pencil is shown wherein` the barrel lob with its slots I1b, ribs I9b and leads I3b are exactly as shown in Figure 1 but the band 20 isfreplaced by an elongated tubular sleeve 20h almost entirely covering the barrel and having a spring leaf near 2lb punched out of one side so that it may be pressed throughany one of the slots l8b to manipulate the leads whenthe sleeve is slid over the barrel. The sleeve 2Gb 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.

While I have herein setforth a certain preferred embodiment of my invention, it is understood that I may vary from the same in minor structural details, so as best to construct a practical device for the purpose intended, not departing from the spirit of the invention and within the scope of the appended claims.

I claim:

' 1. In a pencil, a barrel, a plurality of segmental leads slidably mounted in and filling the barrel, and means for projectingany of the leads from the barrel independently of the others.

2.A In a pencil, a barrel, a plurality oi leads of sector-like cross section slidably mounted in and lling the interior of the barrel, ribs extended longitudinally in the barrel separating the outer sides of the leads, the said' barrelalso having longitudinally extended slots registering with the leads, and means mounted on the barrel for engagement with the leads through the slots for selecting and projecting any lead from the barrel.

3. In a pencil, a barrel, a plurality of leads of sector-like cross section slidably mounted in and filling the interior ofthe barrel, ribs extended longitudinally in the barrel separating the outer sides of the leads, the said barrel also having longitudinally'extended slots registering with the leads, and means mounted on the barrel for engagement with the leads through the slots for selecting and projecting any lead from the barrel, the said means comprising an elongated tubular s leeve loosely tting the barrel, a spring ear on the sleeve for engaging the leads, ribs projected outwardly from the barrel at one end between the said slots for engagement by the sleeve to constrict the barrel on the leads, anda cap threaded on the sleeve enclosing the end of the barrel.

4. In a pencil, a barrel, a plurality of leads of sector-like cross section slidably mounted in and lling the interiorof' the barrel, ribs projecting inwardly and longitudinally extending along the interior of the barrel between the outer sides of`V the leads, the said barrel also having longitudinally extending slots registering with the outer sides of the leads, an annular band loosely and slidably Vmounted around the barrel, and a laterally projecting ear on the band adapted to engage the leads through the said slots whereby any one of the leads may be projected out the end of the barrel.

5. In a pencil, a barrel, 'a plurality of leads of sector-like cross section slidably mounted in and filling the interior of the barrel, ribs projecting inwardly and longitudinally extending along' the l mounted around the barrel, and a laterally projecting ear on the band adapted to engage the leads through the said slots whereby any one of the leads may be plojected out the end of the barrel, and pressure ribs extended outwardly from the barrel adjacent one end and adapted to con- 40 strict the barrel onthe leads when the band is slipped over the Vsaid pressure ribs.
