, the head C is turned round, the tube D remains stationary, while the lead-sheath Eis moved in or out by the action ofthe flat spiral G upon the toe j'.
Cn the tube D is secured the revolving latch L In the example shown in Figs. 1 to?, in-
elusive, lthis latch consists of a ring which is situated between two collars, i i0, fastened on the tube D, so that it can freely revolve, but is prevented from moving in the direction of the axis of the tube D. This ring is provided with one or more teeth, i,.and in the example illustrated by the drawings I have shown three such teeth to correspond in number and position to the three slots b b"3 bo* inthe tube When the head C is in the position shown in Fig. 1, the lead is retracted and the teeth of the latch I abut againstthe upper ends of the slots b b03 b, so that they prevent thehead C from following the action of the spring H beyond the position shown in Fig. 1. 1t' the head C is pressedinward, the teeth of the latch Iineet the inclined faces of the' teeth b of the tube B, [see Fig. 2,) and bythe time the head C has been pressed inward to the position shown in Fig. 3 the Vteeth of the latch have moved down over said inclined faces ofl the teeth 110, the latch I is slightly turned round its axis in the direction of arrow 1, and its teeth strike the bottom of the teeth b", thereby preventing the head CA from being depressed beyond t-his position. .lfthe head C is now released, the latch is, carriedup with the tube D and the teeth of said latch strike the inclined faces ofv the teeth b9 of the tube Boland as they slide up on these faces the latch is again slightly turned in the direction of 'arrow 1, and the head C is finally arrested in the position shown in Fig. 4, leaving the lead exposed for use. Vheny the head C is again depressed, the teeth of the latch I strike the inclined faces of the teeth bo ofthe tube B and the latch is again -in the cage.
slightly turned in the direction of arrow 1, so that when the head C is released its teeth meet the inclined faces of the teeth b9 and are conducted into the slots b02 b3 bo, so that the head C is carried backto the position shown in Fig. 1, bringing the lead in to its retracted position. Q
' In t-he example shown in Figs. S `to12 of the'drawings, the letter A designates a tubu# lar easing open at both ends, the lower end being made tapering. -Inthe interior of this casing. near its lower end, is firmly seciired a cage, D, on one side of. which is formed a toothed rack, a; ywhile from its opposite side projects a dog, b.
lnto the upper end of the casing A is fitted the hollow head C, from which extendsatube, D, down through the top of the cage Band into said cage, as seen in Fig. 12. Freni oppositesides of the tube D extend two arms, .cpcJ` whichengage withlongitudinalslotsdd,for|ned In. the interiorof the tube D is situated the'shcath E, which contains the lead,
F, the lower end of the tube D being split, so as to formspring-jaws e e, Fig. 1, which grasp the lead, F, with an elastic pressure. From the lead-sheath E projects a toe, f, which extends througha slot, g, in the tube D, Fig. 12, and engages a ,flat spiral, G, which is secured to the head C by any suitable means-#sueltas pins h h. The tube C, so that the latter can turn freely in either direction independent of lthe tube, while both' are compelled to move together inthe direc tion of ,their length. For this purpose a pin, c, may be employed, as shown in Fig. 1,2.
Between the upper end of the cage vB and the inner end of the head C is placed aspiral spring, H, which is wound in a direction opposite to that of the spiral G, and which has a tendency to throw saidl head lup to the position shown in Figs. 8 and 12. In this position the head is arrested by the arms c c coming in contact with the upper ends of the slots d d, Fig. 12, while the lead-sheath E is compelled to follow the movements of thehead by the engagement of the toe. f with'- the -flat spiral G. If the head C is tprned round, the tube D remains stationar l moved in or out by the action ofthe flat spiral G upon the teef.
On` the tube D is firmly secured a pin, i', which forms thel axis for revolving latch I. In the example shown in Figs. 8 to ll, inclusive, this latch is 'made in the forni of a starwheel, which has six teeth and six recesses,
which are of unequal'depths, the deep. recesses'v t" t" t" alternating with the Shallow reccsses'zM1 it i2, Fig. 13. A
The latch is exposed arm, i3, which presses upon it so'as to produce sufficient friction to prevent it from Iehanging itsI position accidentally,
C is in its highest position, Fig. 8|, the upper tooth of thisraclc engages one of the deep recessesfi ofthe latch I. lf the head C is de pressed to the position shown in Fig. 9, the axisi of the latch tooth a of the rack a., and if the head is depressed a little ni'ore one of the teeth strikes the dog b of the cage, and the latch is turned to the position shown in Fig. 9. If the head C is now permit-ted to follow the action of the spring H, the tube D'moves up and one of the shallow recesses li2 of' the latch engages the tooth aof the rack-a.; ,This tooth is a little longer than the remaining teeth of the rack, so. that if the same engages one ofthe shallow recesses i2 of the latch, see Fig. 11,) it forms a stop, whereby the latch is locked and the lead is retained in the position shown in Fig. 11, so that it can be used for writing. It the "while the leadsheathE isl is carried below the lastl D is secured to the head to the action ofa spring-l and it (t-lielatch) engages the rack a in' the cage B, and if the head IIO head C-is again depressed, the latch l'strikes` f the dog b, so that it turns in the direction of the arrow-marked thereon in Fig. 10,and when the head-is released o ue of the deep recesses i of the latch engages the long tooth a' ot' the rack a, so that the latch can turn and the head rC, together with the tube D andthe lead con- .tained therein, are carried up by the action of the spring H to the position shown in Fig. l. From this description it will be seen that by 5 v-pressing the head C clear down and then rethe lower end of the tube D', and by nrst depressing the head C'and then releasing it the pen is locked in the position shown in Fig.1l, ready for; use, and i'f then the head is again depressed and releasedv the penis carried back vinto the casing A.
'In order to be able to feed the lead forward asits point wears off 1 insert the same into the sheath E, which slides in the tube D, and whichis moved in or out by turning the head C, as already explained.
What I claim as new, and desire to secure 1. The combination,with casingA,the springsupported head G, fitted into said casing, and the tube D, carrying a pen or lead, of a latch, 1, actuated by bthehead C and constructed to lock the tube D in its forward and 4also in its retracted position, substantially as described,
whereby the latch is thrown in its locking po- .,sition by rst depressing and then releasing the h eadC, and in its unlocking position a1- lewing'the tube D to recede by depressing and releasing the head a second time, as set forth.
2. The combination, in a pen orlead holder, of the tubular casing provided interiorly with upper and lower teeth, the spring supported head, the pen or lead holding tube, and the latch mountedon the said tube and having a .tojseries of teeth and locked in astationary posibe seen that the pen P is inserted directlv into tion to hold thetube advanced bydepressing` and then 'releasing thehead, and unlocked to permit the tube to recede by again depressing .and then releasing said head, substantially as described.
3. The combi of 'thecasing A, having the lower fixed tube B, provided with teeth bo, the' upper 'tube B0',
provided with teeth b, and slots bU2 bfi bof, the spring supported headf. the pen nr lend bolding tuheu., andthe revolving toothed latch I,
-mounted on said lholdingtube and revolved by the teeth. substantially'as and for the purposes described.
et. The combination of the casing A, the non1otating pen or lead holding tube D, the springsupported head C, loosely connected with the tube, the'spiral G, connected with'the head, the sheath E, arranged in the holding- 'tube and having'atoe, f, projecting through the latter and engaging the spiral, a rotating toothed latch, I, mounted on the lead-holding.. tube, andupper and lower teeth in the casing i for turning the latch, substantially as de- 5. The combination, with the Casin;r A and the springsupported head C, of the tube D, the spiral G, carried by the head and made' to embrace the tube D, the lead-sheath E, tit-ted into the tube D, andthe toef; made to project from the sheath Ev through a, slot in. the tube ation, in apen or lead holder,
D and engaging the spiral G, substantially as described.
In testimony whereofI I have hereuntose't my hand 'and seal in the'presence of two subscrib` ing witnesses.
