1 Claim.

It will be noted that the slots of firmly holding crayons of different diameters 15 extend from the forward end of the barrel, as well as tapered crayons.

I 55 through the corrugations 14 and to the threads By pressing the threads 13 outwardly f the barrel, and by having the end 1'! of the thimble at least as great as the internal diameter of the barrel, a crayon of the largest size that can be inserted in the barrel can be slid between and clamped by the fingers in writing position.

In Figure 6 the modification consists in forming only a few lugs, corrugations, or threads 21 at the free ends of the fingers and providing unthreaded sections 22 at the upper portions of the fingers. This renders the fingers slightly more flexible and thus slightly less effort is required in screwing the thimble into clamping positionbarrel between the two extreme positions shown,

is relatively short, due to the provision of the expanded portion of the thimble which accommodates the fingers when a crayon of large diameter is used and the relatively rapid compression of the fingers which occurs when the thimble is screwed upwardly. Thus just a. few turns of the thimble are necessary in clamping the small end of a crayon in position after discarding the large end of a previous crayon.

While I have shown and described certain em bodiments of my invention for the purpose of illustration I do not wish to be restricted specifically thereto except as so limited by the appended claim.

I claim:

A crayon holder comprising a tubular barrel having its lower end slotted longitudinally to provide a plurality of radially flexible fingers, the lower ends of said fingers being provided with a plurality of transverse corrugations on both the outer and inner surfaca thereof, said outer corrugations extending outwardly beyond the original outer surface of the barrel, a portion of said barrel adjacent the upper ends of said fingers being threaded, and a clamping thimble having a frusto-conical portion provided with an p nin at the lower end,'said thimble having the upp portion thereof threaded for cooperative engagement with the threads of said barrel and having a diameter suflicient to accommodate said cormgated fingers whereby the large end of a tapered crayon can be positioned between the lower ends of said fingers for engagement by the lower inner corrugations thereof as the thimble is screwed rearwardly of the barrel to cause said conical portion of the thimble to engage the outer corrugationsof' the fingers and compress the same ra-- dially to force the lower inner corrugations into engagement with the crayon, the threaded portion of said thimble being of such length that said thimble can be movedrearwardly of said barrel sufileiently to cause the forward ends of the fingers to project from the thimble and be compressed by the coaction of one or more of said .outer corrugations and the lower end of said thimble into gripping relation with the small end of a tapered crayon.
