PENCIL-HOLDER WITH ADJUSTABLE (103E.

Specification of Letters Patent.

Patented Nov. 5, 1912.

Application filed January 16, 1911. Serial No, 602,889.

To all when 'it may concern:

Be it known that I, Encnmnn'r GER- SPACIIER, a subject of the Emperor of AustriaI-Iungai-y, and resident ofV I Stumpergasse 23. Vienna, Austria-Hungary, have invented certain new and useful Improvements in -Iencil-I-Io-lders with Adjustable Cores, of which the following is a specification.

IIeretofore pencil holders with adjustable cores have been made where the core 'is yieldingly supported and where the shell is arranged movably in a corresponding bore of the holder. "ilh these holders, :1 piece of wire is used to support the core and the arrangement of the wire in the holder is eflected in such a way that the exchange of the core is complicated, since the said wire piece must be taken out, together with the core,

in order to efi'ect the said exchange and must be inserted together with the new core, and with the core shell, into the holder.

According to the present inventionthe support of the core is effected by means of a yielding piece of sheet metal wire or string inserted into the holder diametrically to the longitudinal axis'of the same and near to its outer end, the whole arrange ment being effected in such a way that the exchange of the core is produced by simply pulling out the core shell inserting into the same a new core and replacing the shell into the holder.

Vith the holders of this class the elasticity of the support is obtained by means of a spring arranged upon the end of the holder and hence the exchange of the spring, in

case of emergency, becomes very difiicult.

without impairment of the holder, since access to the spring, with ordinary tools, is practically impossible. As, according to the present invention, thespring is arranged near to the free end of the holder, and renewal may be easily efi'ected.

Figure 1 is a view in side elevation of a pencil embodying my invention, parts being shown in longitudinal central section to disclose details of construction. Fig. 2 is a view similar to Fig. 1 showing a modifieation of my invention. Fig. .3 is a fragnientary View of the core end ofapencil, a

modification of my invention, parts being shown in longitudinal, central section to disclose details of construction. Fig. 4' is an end ,view of the device shown in Fig. 3. Fig. 5 is a view similar to Fig. 3 showing a further modification of my invention. Fig. 6 is a view similar to Fig. 5 showing a still further modification of my invention. Fig. 7 shows a View of the core shell. Fig. 8 shows a modification of the spring illustrated in Fig. 5 and Fig. 9 shows a bush in side and end views respectively for fixing the spring in the holder.

A is the holder having a bore (1 The. shell B is inserted onto the holder A. (I- is the core and D is an additional tubularholder piece with bottom 6. The core shell B is provided with two oppositely disposed grooves c c which are open to the slot (Z and extend longitudinally through the head piece e for the reception of the cor-e 0.

Near to the free end of the holder an elastic piece of'wire is drawn through holes 7", the wire being preferably bent in its central part, as shown in the drawing, and the size of the wire being chosen so that it fits into the longitudinal slots (1. The core shell is moved into the bore and the wire acts as an abutment of thecore. It will be readily seen that every inward movement of the core shell causes the core to move outwardly from i obtain a quick outward movement of the core, by the said sheet metal piece, the latter is made of hardened steeland is provided with a perforation i (Fig. 4) in such a manner that a narrow cross-piece is left against which abuts the core of the holder, this cross piece having sufficient elasticity to effect outward movement of the core.

In order to increase the elasticity of the inserted piece of wire and also to facilitate the fixture of this piece into the holder it is preferably to employ a 'piece of wire which is bent several times in opposite directions,"

snakelike, one shank abutting againsta projecting surface of the' holder and the other shank abutting against the core. Thereby the degree of elasticity of the core support is considerably increased. The introduction. and the exchange of the spring is effected in a simple way either with the aid of a somewhat larger diameter to accommodate a bush E (Fig. 9) slotted in its upper part and serving for taking a spring, bent in op posite directions. The bush E together with .the spring is inserted into the holder A the spring resting with its upper part against the bottom of the bush excavation and resting with its lower part against a flange-of the bush E the intermediate parts of the spring resting within the slot of the bush E. The bushing E is shifted into the bore of the bush in such a way that the spring entersalso the axial and corresponding slots of the core shell B. The core 0 abuts against the shanks of the springs and moves outwardly after shifting back the core shell into the holder. 1

In case of the core not projecting outwardly from the shell the desired distance it will be suflicient to press the head piece 6 of the shell againstany rigid surface in order to tension the spring of the latter causing therefore the outward movement of the core after releasecof the pressure upon the head piece e. The additional bush piece E may also be dispensed with and the slot h for taking up the spring may be provided in the holder (Fig. 6) the spring ends abutting against the lower and upper walls respectively of the slot. The spring may also be sha ed in such a way that its upper shank 'pro]ects centrally and longitudinally in the direction of the core (Fig. 8). The lower end'of such a spring abuts against the wall of the slot and the longitudinal projection of the spring is carried through the central groove of thecorshell B and abuts against- -the core itself.

Having now described the nature of my invention and in what manner the same is to be performed what I claim is a 1. A pencil comprising in combination, a body portion, a shell carried by said body means carried by said body portion adjacent the mouth of the said core in the latter, adapted to form a yieldable abutment for the core in said shell.

3. In a pencil of the character described, the combination of a core, a shell therefor, a holder adapted to receive said shell and provided with recessed portions, the said core, shell, and holder being movable with respec to each other, and a relatively flat spring bent alternately in opposite directions carried by said recessed portion of said holder and disposed with its plane in the line of movement of said core, the spring forming a yieldable abutment for the latter.

4. A pencil comprising in combination, a body portion provided with a longitudinally extending bore and a second bore of larger diameter at the end of said body portion and opening into said first mentioned bore, a bush adapted to be inserted into the larger of said bores of said body portion and provided with a bore adapted to register with said first'men'tioned bore of said body portion, said bush having oppositely disposed slots disposed laterall of the bore therein, a core, a shell provided with a bore for said core and having slots disposed laterally of the said bore in said shell, said shell being adapted'for insertion into the said here of said bush and first mentioned bore of said body portion, and a relatively flat sprin disposed within said slots of said bush and shell forming ayieldable abutment for the said core.

In testimony whereof I 'affix my signature in presence of two witnesses.
