Specification of Letters Patent.

For adjusting the length of the crayon the 110 The rear end of the barrel is also provided outer casing 12 is first removed, the tube 11 with external screw threads to receive the and collar 3 are also removed from the outer end and the sleeve 9 may then be slipped off of the barrel 2, though this may not be necessary. The crayon within the barrel may be projected from the open end thereof by proper rotation of the rod 7 as described, after which the nut 3 is threaded upon the members 2 until the crayon is securely clamped in the barrel. Nhen fresh crayon is inserted in the barrel 1, it is necessary to remove the cap 5 from the rear end thereof. The crayon is now placed within the barrel and is forced from the open end thereof, when the cap may be readjusted in position. The head 7 of the adjusting rod 7 is of course disposed in contact with the rear end of the crayon and the milled head 8 manipulated until the proper length of crayon protrudes from the open end of the barrel. lVhen the first portion projected is used up the adjusting rod is threaded inward to present a fresh marking portion un til the crayon has been entirely consumed.

Thus it will be seen that I have provided a crayon holder wherein the chalk will be securely held in position when it is desired to use the same, and may be rapidly adjusted in the tube or barrel so that the same may be always ready for instant use. The parts comprising my improved holder are very few and of extremely simple construction, which are very quickly assembled or disassembled. The sleeve 9, cover 11, and outer casing 1:2 are all to be made of aluminum, whereby the device is rendered extremely light, so that the same may be quickly handled.

The nut 4, cap 5 and adjusting rod 7 are preferably constructed of brass, though it t will of course be understood that the same may be formed of any other material applicable to the purposes for which the same are designed.

The barrel 1 would preferably be formed of sheet steel to secure the proper resiliency of the plates 2.

After the crayon has been properly adi justed from the end of the barrel, the sleeve 9 and the outer casing 12 may be replaced to provide a smooth surface by which the holder may be firmly grasped and manipulated.

When the parts are assembled as shown in Fig. 1, the recesses 10 formed in the end of the barrel 9 receive the lugs 5 formed upon the cap 5, and when the casing 12 is removed for the purpose of adjusting the crayon from the end of the barrel, any rotative movement of the cap and barrel will be prevented.

It will be understood that the crayon may be of any convenient size and that the proportions of the various parts may be altered without materially effecting the construction or operation of the holder.

Having thus described my said invention, what I claim as new and desire to secure by United States Letters Patent is:

A holder of the character described comprising a hollow split barrel, a clamping nut adapted to have threaded engagement with one end of said barrel, a cap upon the other end of said barrel, lugs integrally formed with said cap at diametrically opposite points, an adjusting rod threaded through said cap, said rod having a plunger head upon its inner end, a. collar disposed upon said barrel, a cylindrical sleeve surrounding said barrel and extending between said cap and said collar, said sleeve having recesses formed in one end thereof adapted to receive the lugs formed upon said cap, a tube provided with internal screw threads adapted to be threaded upon the split end of said barrel, and a casing disposed over said barrel in threaded engagement with sleeve.

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

GEORGE A. TUCKER.
