PENCIL-CASE.

To all whom it may concern:

Be it known that I, JosEr WERNER, citizen of Germany, residing at Munich, Bavaria, Germany, have invented certain new and useful Improvementsin Pencil-Gases; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

In pencil-cases according to the prior art, in which the lead is adjusted bymeans of a member sliding on the case, the connection of the lead to said sliding member has always been rigid; the consequence is that any shock to said member, for instance,

when the case falls to the ground, will be transferred direct to the lead and frequently I cause it to break. Further, the leads themselves are seldom perfectly straight and it was therefore heretofore found necessary to ive the. lead a certain amount of free play in the front aperture of the case, in order to prevent breakage of the lead whenadjusting; for purposes of writing and drawing it would however be very desirable for the lead to fit tightly into the front aperture of the case.

The present invention provides a pencil case in which, on the one hand, all shocks are lessened and breakage of the lead thus avoided and on the other handthe lead is guided inthe front aperture of the case without free play, fitting tightly into said aperture without fear of crooked leads"be coming broken when adjusted. These advantages are attained by interposing between the lead and the above-mentioned sliding member'a more or less elastic or flexible element, which imparts all axial movements of the adjustable sliding piece direct to the lead but at the same time weakens all outward shocks and also allows of a certainamount of lateral motion in the case of crooked leads. This connecting element may consist of a coiled spring, or of a pin or bolt having at either end a ball and socket joint or similar connection.

Reference being had to the accompanying drawing Figures 1 to 5 show a pencil case in which the connecting element between lead andsliding member consists of a coiled spring, Figs. 2 and 4 being views, Figs. 1 and 3 longitudinal sections and Fig. 5 a cross-section. Fig. 6 is a longitudinal section through a pencil case in which a bar Specification of Letters Patent. Application filed April 28, 1910. Serial No. 558,254.

In the forms ofconstruction shown in Figsal to 5 the lead an isheld at its rear end by a coiled spring (2 adjustable in the longi-- t-udinal cavity 1) of'the case 0. The rear end of said coil-spring (Z is connected by means of an an able slidingmemberf. i r

In the form 'ofconstruction according to Figs. 1 and 2 the connection between the pin e and the sliding member f- .is attained by means of a metal strip Z projecting laterally through the longitudinal slit g of the pencil case and fixed to said member .The

lar .pin' 6 or the like to the adjustsliding member fcan be fixed in position by a ring or collar m, axiall adjustable on over small wedge-shaped;projections n of the lower and slitted portion of said mem- In the form of constructionaccordin'g to Figs. 3, 4 and 5 the sliding member for adjusting the lead in the case is formed by a strip of metal f connected to the pin a and projecting. through the slit 9 of the casec, being then bent around saidcase. In order to fix this sliding'member in its position, -a ring it having an aperture or recess is, cor:

(responding to a wedge-shaped projection 71 of the sliding piece 7, is adapted to be turned on said sliding member. By turning over the sides of the metal strip f, so as to form a raised bordero, the ring it can be prevented from sliding off the part f.

:The action of the device is similarin bothv forms of construction. In the firstmentioned (Figs. 1 and 2) the ring m, when pushed downward over the projectionsn, n will press the lower slitted portion of the sliding member f against the case and thus secure it in position. In the second form of construction the turning of the ring it in the direction of the arrow (Fig. 5) will have the same effect.

According to Fig. 6 a bar or bolt 77 is provided at either end with a ball and socket joint 9, the lower joint connecting with the inwardly projecting part of the sliding member 1". Instead of the ball and socket. joints any other'universal joint allowing of movement in any direction may be used.

If necessary, the sliding member in all the above-mentioned forms of construction may be provided with concentric rings .or/ ribs in order increase the spring action to be pushed and the friction between said sliding member and the case, and thus to facilitate its secure locking in position. The parts 0 shown in the drawing may, for instance, be adapted to form such ribs.

The lead a may consist of any desired material such as graphite, charcoal, chalk crayon, copying-ink or the like;

\Vhat I claim as my inventionland desire to secure by Letters Patent is:

1.A device of the character described comprising a longitudinally bored case having a lateral slot therein, a lead contained in the bored case, means for moving the lead including a member passing through the slot in the case, and a laterally yieldable resilient elementinterposed between the lead and said'member, one end of said resilient element engaging the lead and the other end thereof engaging the member passing through the slot in the case, the part of said through the lateral slot into the case, said projection being adapted to move the lead in the ease, and a laterally yieldable' resilient element having one "end engaging the lead and g j the other end engaging said projection, the v part of said resilient element intermediate its ends being; capable for" free lateral distortion, and the diameter of the bore in said case be ng g'reatcrthan the diameter of either said lead or said resilient element.

. A device of the character described comprising a longitudinally bored ease havmg a lateral slot therein, a lead movable in said ease,- means for mo'vingthe lead comprising a sliding member haying a projeo" 'tion extending through the lateralislot in the case, a coiled spring having one end; en-

gaging said lead, and a pin connecting the other end of the coiled spring With said projection, the portion of said coiled spring intermediate its ends being capable of free lateral distortion, and, the diameter of the bore in said case being greater than the diameter of either said lead or said coiled spring. 1 v v k 4. A device of the character described ment intern'iediate its ends being capable of free lateral distortion, and means for looking said projection in adjusted position, the diameter of the bore in the case being greater than the diameter of either said lead or said resilient element.

5. A device of the character described, comprising a case having a longitudinal bore one end of which is exactly of a diameter to retain a lead without play, said case having a lateral slot in the wall thereof, a laterally yieldable resilient element connected at one end to one end of the lead, the diameter of the bore in the case at points other than the'said end thereof being greater than the diameter of either said lead or said resilient element, means for longitudinally moving the lead, saidmeans being connected to the end of the resilient element opposite that to which the lead is connected,'a projection on the lead moving means, and an apcrtured member adapted to be moved into engagement with said projection to retain the lead moving means in adjusted position;

In testimony whereof I hereunto affix my signature in the presence of two Witnesses.
