HOLDER FOR PENCILS.

SPECIFICATION forming part of Letters Patent No. 364,303, dated June 7, 1887,

Application lled March 15, 1886. Serial No,195,334. (No model) Patented in Germany November 1D, 1885. No. 35,867, and Novemlmr21.1885,No.36,478; in England December l?, 1885, No, 15,533, and in Austria-Hungary July 52, 1F86.

To all whom it may concern:

Be it known that I, MORITZ SACHS, a subi ject of the King of Bavaria, residing in Nuremberg, Bavaria, Germany, have invented a new and useful Improvement in Holders for Pencils and Similar Objects, (for which I have obtained patents iu England, No. 15,533, and dated December 17, 1885; Germany, No. 35,867, November 19, 1885; patent of addition thereto, No. 36,478, of November 24, 1885, and Austria -Hungary July 2, 1886,) of which the following is a specification.

My invention relates to t-he contrivauce for feeding forward, withdrawing, stopping, and releasing the movable core or tube of holders for pencils, pens, and other small instruments.

In describing the invention reference will be made to the accompanying drawings, of which- Figure 1 is an axial section 0f an improved pencil-holder, the movable core being withdrawn; and Fig. 2, an axial section of the same, the movable core projecting. The remaining figures represent. modifications and details.

The outer tube, a, contains the black-lead tube b, fastened at its lower extremity. The blackdead tube b is furnished with a long slit, b', and two lateral recesses, bz. To the tube b is fixed a small tube, c, furnished with elastic cheeks c', which catch into the' recesses b. The tube b contains the black-lead d, over which lies freely the slide g with the catch g. The latter projects from the tube slit b' and catches into the screw-thread hof the tube h. This tube h is adapted to revolve the tube Z), and also (as in pencil-holders with so-called English guiding to be displaced longitudinally thereon. lt is raised at the projection h2 by the spiral spring i, resting on the bent portion a of the tube, acts in raised position, Fig. l, with its bent lower extremity, h3, on the clipping-checks c', and project-s with its up per end the tube-head h* from ont of the tube a. By pressing on the tube-head h, Fig. 2, the slide g g is moved longitudinally Within the tube h h', and thereby the blaclolead released from the clipping-cheeks is fed forward. When the pressure on the tube-head h ceases, the black-lead remains in the forward position, if the holder lie horizontally, while the tube h h', with the slide g g', gets back again intothe original position and clips the blaclolead fast again. By a further pressure on the head h, while the point' of the holder is held upward, the lead can be brought into the original position, as in Fig. 1. rlhe slide g g' being also adapted to be shifted by turning the tube h h', this slide can, with the varying length of the black-lead, always be put in a position which allows the black-lead to be fed forward in the requisite amount for use by pressing the tube-head 711i. The blacklead, of course, cau also be fed forward for use by Inerely turning the tube h.

Figs. 3, 4, 5, and G represent likewise a holder with feed mechanism. This device is equal to that of Figs. 1 and 2, with the only exception thatin theholder shown by Figs. 3, 4, 5, and G the black-lead d is rigidly connected with the slide g g', and the small tube c with the clippingcheeks c and the tube-recesses b2 are omitted. Owing to the connection of the black-lead d with the slide g g the black-lead d, if'only the arrangement shown by Figs. 1 and 2 were applied, could be propelled by longitudinally displacing the tube Il., but could not be retained in its forward position. For attaining the latter purpose a stopping and releasing dcviee is arranged, which, as it will be shown, may also be applied to holders with differently-constructed feed mechanism.'

The stopping and releasing device consists,

(Fig. 3,) first, of the elastic catches k, fixed to the tube a; second, of atube, m, secured on the tube It, and provided with an outslandi ng ring, m', preferably of an ogival or conical form, adapted to arrive between the catches 7c and press the same apart, so as to arrive in front of them; third, of the ring n, sliding ou the neck h5, above the said conical part mi', and having an exterior diameter somewhat larger than the base of the said part m', its travel on the said neck h being limited downwardly by the said conical part m' and upwardly by the flange h".

By shifting forward thesleeve h h,and there fore the slide g g'with black-lead d, by press ure on the head h the ring m' passes between the points of the catches k and the latter rest on the neck h, and the base of the ring m is pressed back onto the said points by the action of the spring i, so that the tube h h', and there ICO fore the black-lead (l, (or pen, crayon, or the like) is held firmly in its forward position. When the black-lead is to be released, the head h* is pressed farther downward into the ease, by which means the flange h arrives on the ring `n and forces the latter downward between the points of the springs lr. 0n releasing the head h the slide h h', with all the parts lr h m' n, is moved upward in the case by the spring 'i'. By this means the base of the ring m arrives against the ring n, forcing the latter from between tlie catches k, which slide off onto the sides of the ring m', so as to free the latter, and the whole mechanism resumes the position shown in Fig. 3.

Fig. 6 is a cross-section of Fig. 5 along line A B. As also this arrangement permits the tube h h' to turn on the tube b b', the slide g g' can also here, when the length of the blacklead changes, be brought into a position which allows the black-lead to be shifted forward for use by pressing the tube-head h. Moreover, here the black-lead can also be fed forward as well as withdrawn by merely turning the tube h h. 'The feeding forward and withdrawal of the black-lead can here be effected in any position of the holder by pressing as well as by turning.

I do not confine myself to any particular lshape or number of catches, la. Also, I may replace the screwthread pressed into the material of the sleeve h by a helical rail fixed to or formed on the inner surface of said sleeve.

The arrangement of the separate parts of the stopping and releasing device may also be different from that shown by Figs. 3, 4, and 5. Figs. 7, 8, 9 represent such a modification of a holder, with a part, h, simply adapted to slide longitudinally, which, as in the holders hitherto described, is in connection with a spiral spring, i'. Here the catches are fixed to the part li and tend to expand or separate from each other by their elasticity. The slide-surface m, with the projection m', however, is situated on the stationary tube a that is to say, they are formed by this Very tube, and themovable ring n may be displaced within the limits m' and h, Fig. 7. The arrangement is here made so that by displacing the part h (which may carry a pen, o, or a black-lead and such like) the catches k, which press against the sliding surface m, slide on the latter until they arrive behind the projection m', where they spread so as to abut when the pressure ceases on the said projection and be retained thereby, as shown in Fig. 8. When the part li is again fed forward, the catches k are pressed together inwardly, Fig. 9, by the ring n, situated at the limit h, and they are held in this position by the ring a until the latter is suddenly thrown upward with the parts k k by the spiral spring i, when the pressure on h* ceases and is stripped off when abutting against the projection m' by the catches k, which thereby get on the sliding surface.

With holders in which the movable part h is not turned the movable part n need not b e ring shaped. This part may, for instance, if the stopping device is arranged as shown by Figs. 3, 4, and 5, consist of two small parts of a ring connected by a pin, which partsarc guided and stopped by a pin working 1n a slot of the neck lr" ot' the tube.
