To aZZ whom, it may concern: 1

Beit known that l, OTTO BUSSLER,ofNuremA berg, in the German Empire, have invented certain new and useful Improvements in Lead Pencil Gases, (For which Letters Patent were granted in England in 1886, No. 275, and also in Germany, No. 37,88l;) and I hereby declare the following to be afull and clear description thereof.

This invention relates to a pencil ease or holderof that class in which the lead or pencil proper is held ina concentrically-surrounding case or holder in such a manner as to be fed forward in its said case as its front end is said ease being accomplished by the forward pressure or manipulation of some part of or appendage to the inclosingcase.

The specilie parts of the said case or holder which forni the especial features of this invention are a double holder or a pair of actuatingcases each of which is made to grasp the vinclosed lead and is actuated by a special spring so that they may be operated partly together and partly separately, in a peculiar manner (hereinafter fully explaineth) which aetuates or moves forward the lead, as desired.

The invention will be readily understood by reference to the accompanying drawings, of which- Figures l, 2, and 3 are full-length sectional elevations of the improved lead-pencil case or holder, showing in each of the said figures, respectively, the operative part-s thereof in dif* ferent positions. Figs. t and 5 show sectional elevations of the frontend portions of the said pencil cases or holders.

The outer or inclosing case consists of two parts, h and It', which abut together, end to end, and are secured together by screw-threads. The longer part, h, of this case constitutes about threed'onrths of its whole length, and the other part, k', about one fourth of its length. The forward part of the said case h carries twoinwardlyprojecting anges, h`l and ha, the fiange if being located just at the front end of the said case and the dange h3 a short distance--say an inch or two, more or lessto the rear of said dange h2, so as to form between the two said flanges a sort ofcylindrical eha1nber,in which the ring r slides forward and backward in the manner and for the purpose presently explained. The forward end ofthe forward section, 11,',of the outer case also has an inwardly-projecting ange, h4, which forms an abutment against which the spiral springfis seated and presses. The rear face of the innermost iiange, h, also forms an abutment for the actuating spiralspring f to press against.

There are two inner cases or grips, a and b, which are respectively seated coneentrically in the cuter cases, 7L and'li, and slide longitudinally therein. The iront end oteach of these sliding eases is slotted, and has its extreme end turned inwardly, so as to form grips or lips c and c', between which the pencil d is gripped and held longitudinally in position, as below described. The springf, having its front end abutted against the front end iiange, 11i, and its rear or inner end against the flange c', atthe inner end ofthe sliding case or holder a., acts thereon to habitually throw the sliding case a inward in its housing-ease h', yet permitting it to move forward in the said Casoli', as presently explained. This grip-case @,when thus thrown inwardly by the springf, has its outwardlyilaring frontend, c, pressed against theinner face ofthe iront aperture in il., thereby causing it to spring inwardly, (its front end being slotted, so as to permitit to do so,) and by this gripping movement ofthe case a its extreme front end is pressed inwardly, so as to inipinge against the pencil d, which is thereby held fast at the extreme front end of its holder. The inner or rearward sliding gripcase b has its slotted frontend surrounded by a sliding ring, r, which said ring when thrown forward on the said slotted front end of the tube b causes the lips e at its extreme front end to press inwardly and impinge tightly upon the lead-pencil d, so as to hold it iirrnly at that point; but when the said ring is thrown rearwardly on said tube b the jaws or lips c' rest lightly against the periphery of the lead d, which is then permitted to slide easily forward or backward within the saidjaws.

The spiral springf, arranged as shown in the drawings, with its front end abutting against the dange'h3 and with its rear end roo against the collar b', attached to the case b, acts to habitually throw the said grip-case b inwardlyin its housing-case h, and thereby the sliding collar also is drawn back on the outwardly-springing slotted front end of the case b until it impinges against the front face of the flange h3, which causes the said ring to stop, and then the spring f continuing to act,presses the tube b still farther inwardly, the said tube b meanwhile sliding within the ring r, which is thus relatively moved forward on the said sliding tube and up n its outwardly-springing front end, thereby causing the lips c to impinge tightly upon the sides of the lead d, which is thus firmly grasped at a second point. The rear end of theinnertube, b, extends back beyond the rear end of the case h far enough for a button, 7c, to project sufficiently for the forward movement of the tube b for feeding forward the lead d, as required.

The operation of the pencil-case thus con-v structed is as follows: The cases a and b are' thrown forward, as shown in Fig. 3, when a lead is to be inserted, and in this position the jaws c and c are relaxed as far as possible and sufficiently so to allow the lead d to be inserted longitudinally as far as required, and then, as pressure of the thumb is relaxed from the button 7c, the springsfandf press their respective grip-cases a and b inwardly, and the outwardly-flaring grips c and c' are pressed inwardly, respectively, by the front end of h and the sliding ring r acting as above described. This rearward movement of et and b continues until the rear end of a is stopped against the front end of the flange h2. The grip-cases a and b have a longitudinal movement independently of each other for the purpose of feeding forward the lead d when it is required so to do. Thus when the button 7c is pressed forward, it first causes the tube b to slide forward on the lead d, the grip-teeth c slipping on d for that purpose, while the tube a remains stationary, the spring fpushing it back meanwhile, so as to keep the grip c tightly closedl upon the lead d. Then as the forward movement of the tube b is continued the front end of b c strikes the rear end of a and pushesit forward, as shown in Fig. 3, and

during this part of the movement, or during the latter part of it, the grip c is loosened from the peneils sides and the grip-jaws c push the lead forward in said jaws c, and thus the lead is fed forward.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a lead-pencil holder, the inclosing-ease 7L It', combined with the lead-holding case a, auxiliary lead-holding ease Z, button k, and springs ff', the whole constructed and operating substantially as set forth.

2. In a pencil holder or case, a front cylindrical pencilease, c, centrally apertured longitudinally for the pencil-lead d and provided with an actuating-spring, f, and an outside embracing jaw-piece, h4, arranged to press the jaws c, forming the outer end of the case a, upon the said lead d, in combination with a similarly-formed inner case, b, which is actuated by a spring, f, and provided with a sliding clamping-ring, m, moving longitudinally in an annular chamber in the handle or case ofthe pencil and arranged to clamp the inner case, b, upon the lead d when the said clamping-ring is thrown forward and to release it therefrom when the said clamping-ring is thrown backward, substantially as described and set forth. a

3. In a pencil case or holder, the inner sliding tube or leadgrip, b, slotted and provided at its front .end with inwardly-inclined gripjaws c', adapted to hold the leadin place when it is otherwise released, in combination with a sliding clamping ring fitted eXteriorly thereon and arranged to move forward and backward on the said tube and within a housing formed for it in the outer ease, so as to cause it to press the jaws c upon the lead d when it is thrown forward and release them therefrom when it is retracted, substantially as' described and setl forth.

In witness whereof I have hereunto set my hand in presence of two witnesses.
