SPECIPCATION forming part of Letters Patent No. 296,537, dated April 8, 138%.

Application filed August 15, 1883. (No modem To fili infront t vii/tty con/cervi,.-

Be it known that I, ALONZo T. CRoss,of Providence, in the State of Rhode Island, have invented an Improvement in Crayon-Holders,

5 of which the following is specification.

My invention relates to an improvement in 15 nsed-up cra-yon may at the proper time be automatically thrown to a considerable distance by means of the resilience of the spring.

Figure 1 represents an axial section of a crayonholder having a carrier provided with my improved forcer-spring. Fig. 2 is an elevation ofthe slotted screw-holding tube. Fig. 3 is an elevation of the carrier-tube with an inserted crayon. Fig. Lt represents the several parts of the screw mechanism as secured to each other preparatory to the final attachment of the case of the holder. Fig. 5 is an axial section of the carrier with an inserted crayon. Figs. Gand 7 represent the application of my improvement to the carrier shown and described in my Patent No. 263,392.

In the accompanying drawings, A is` the screw-holding tube, provided longitudinally with aslot, a, the lower end' of which is made wider than its upper portion to form the shoulder b. The lower end of the tube A is provided with the opposite slots c, and the two jaws d d so formed are arranged to spring toward each other, in order to clasp the crayon, and also the lower end of the carriertube B when the carrier is brought down to expel the unused stub of the crayon, and upon the tube A, between' the slots a. and c, is secured the collar e, by means of which the point-tube Gis secured to the tube A.

The carrier for the crayon is formed of a tube, B, made to lit loosely within the bore of the tube A, and provided longitudinally at near its upper end with a slot, f, the upper portion of which is laterally deflected to form 5o a holding-notch for. the pin ofthe forcer, and` the lower end of the carrier-tube is provided with a split, r, for a short distance, in order to adapt the saine for receiving crayons of slightly-differentdiameters.

NVithin the carriertube B is placed the loose] y-moving forcer E, provided with the pin j, which enters the slot f, and, passing through the slot a of the tube A, enters the groove kof the hollow' screw G,which is loosely held upon the tube A by means of the iixed collar g. The forward end ofthe forcer E is provided with a projecting stem, i., upon which is placed the spiral spring h. The plug F, also moving loosely in the bore of the tube B, is provided with a. pin, m, which enters the lower portion of the slot f, and the spring h is made to oecupy the space between the plug F and forcer E, as shown in the section, Fig. l, which represeuts the forcer and plug at their greatest distance from each other, the pins j and m being at opposite ends of the slot f,which forms a limitingstop to the movement of the forcer and plug under the action of the intervening spring. Then the crayon H is inserted into the split end of the carrier-tube, the plug F will be forced backward, causing the compression of the spring h. until the stem i brings up against the rear end of the plug F, as shown in Fig. 5. t

The operation of the holder will be as follows: Upon turning the screw G in the proper direction the crayon will be fed downward to the point o of the holder, and when the crayon has been nearly used up the forward end of the carrier will strike the inner side of the conical end 0 of the point-tube C, and also encounter the resistance caused b v thesprin g action of the jaws d d, which will serve to prevent the car- -rior-tube B from revolving within the bore of the tube A under the continued movement of the screw, which movement will cause the pin j to be moved laterally to a position under the shoulder Z in the slot of the tube A, and also at the same time out of its retaining-notch n `in the slot f of the carrier-tube, after which the continued movement of the screw will ini part a longitudinal movement to the forcer, the pin j passing `forward along the slotf7 and the stem 2'., which is in Contact with the rear end of the plug F,will serve to impart an equal movement to the plug, tending to force the stub of the crayon'out of the carrier-tube; and as the crayon gradually moves forward, the frictional hold upon the same by the spring of the split end of the carrier will become gradually lessened until apoint is reached in which the frictional grip will be overcome by the resilience of the spring, which will then cause the sudden ejectment of the crayon to a considerable distance from the holder, the forward movement of the plug F being limited by the pin m and slotf7 or by any lother suitably-arranged stop. Now, in order to insert a fresh crayon, the movement of the screw is to be reversed and the reverse movement continued until the pin j has been brought to theupper end of the slot f, and then upon the movementr of the pin j into the notch n the crayon may` be inserted into the end of the Carriertube, thus compressing the spring h until the proper degree of insertion has been reached, as shown inFig. 5, and by the continued movement of the screw the crayon may be drawn wholly within the bore of the holder.

I do not of course limit my claim for aspring arranged between the forcer and the rear end of the crayon to any particularform of mechanism for operating the forcer, since my improvement is applicable to carriers that are differently operated-as, for instance, that shown and described in my Patent l No. 263,392, an axial section of which is shown in Fig. 6, with an elevation of the forcer in Fig. 7, thespringh being in this case held in the hollow end of the forcer, as shown in Fig. 6, and upon the ejectment of the crayon H the spring will project beyond the forward end of the forcer, as shown in Fig. 7, land a disk, p, may be soldered to the end of the wire spring, in order to protect the same from injury.

My improved forcerspring may also be adapted to the carriers of ordinary slidepencils in which the screw mechanism is not employed, and in carrying out myinvention in such pencils I prefer to make use of two slidesone secured by pin to the carriertube and the other to the forcer-and upon the arrival of the carrier-tube at its stop at the lower end of the pencil the required additional forward movement is to be imparted to4 the slide of the forcer, and the form of carrier shown in Fig. 6 is adapted for this purpose.

I claim as my inventionl. In a crayon-holder, the combination of the carrier-tube, provided with a split end for frictionally holding the crayon, with means, substantially as described, for imparting .an initial movement to the crayon-stub from the carrier-tube, and a spring for forcibly ejecting the same when the frictional grip of the split end of the tube has become less than the resilience of the spring.

2. In a crayon-holder, the combination of the screw mechanism, and a carrier-tube pro-` vided with a split end for frictionally holding the crayon, with a forcer and a spring adapted to forcibly eject the stub vof the crayon upon the continued movement of the screw after the carrier has reached'its stop at the lower end of the holder.

3. In a crayon-holder, the combination of the screw mechanism, and a carrier-tube provided with a split end for frictionally holding the crayon, with a forcer, a'plug, and an intervening spring adapted to forcibly eject the crayon, substantially as described.
