Kombinerad blyertshallare, -skyddare och -formerare. Combined pencil holder, protector and former.

Prioritet begiird frdn den 13 februari och 29 adobe,. 1940 (Norge). Priority begiird frdn February 13 and 29 adobe ,. 1940 (Norway).

FOreliggande uppfinning avser en kombinerad blyertshallare resp. -skyddare och -forme- rare, vilken utom att den liar en form, som gor att den ãr bekvam bade att anvanda och att bara i fickan ger blyertspennan saker styrning under formerandet saint reglerar detta automatiskt. The present invention relates to a combined pencil holder resp. -protector and -former, which except that it has a shape, which makes it comfortable to use and that only in the pocket gives the pencil things control during the shaping saint automatically regulates this.

Blyertshallaren enligt uppfinningen innefatter tva rar, som kunna skjutas eller skru-vas in i varandra, och av vilka det inre i sin ena ande ar forsett med en fasthallningsanordning for blyertsen oeh tjanar till styrning av denna under formerandet. Enligt uppfinningen aro roren gangade i varandra med mycket liten stigning pa gangorna -vilken stigning at avpassad sa, att blyertsen mains cram med en for formeringen lamplig hastighet. For att fOrhindra aft den formeras mer an som Or nodvandigt kunna gangorna i de tva rOren Tara avpassade sh i forhallande till vatandra, att de komma ur ingrepp med varandra, sa att matningen upphor automatiskt, nar blyertsen Or fardigformerad. The pencil holder according to the invention comprises two parts which can be pushed or screwed into each other, and the interior of which in one of its parts is provided with a holding device for the pencil and serves to guide it during formation. According to the invention, the tubes are interlocked with a very small pitch on the aisles - which pitch is adapted so that the pencil is framed at a speed suitable for the formation. In order to prevent it from being formed more than necessary, the passages in the two tubes Tara adapted sh in relation to water, that they come out of engagement with each other, so that the feeding ceases automatically when the pencil Or is preformed.

Sjalva formeringen kan, for att den skall fit minsta mojliga dimensioner, lampligen be-sin av en av stal framstalld kon, i vars vagg en spiratformig fortlopande slits, vars ena sidokant Or inbOjd och vassad, sa att den bitdar formerarens kniv. Att kniven gar spiralformigt, medfor att den slid'. Mitre On de for koniska formerna vanliga raka knivarna. Man kan emellertid ocksh anvanda en rak kniv, som Or inbojd pa det namnda sattet eller, sasom vanligen Or fallet vid koniska formerare, en stalkniv, som Or fastskruvad tangs kanten .av en slits i kon.en. Formeraren Or enligt uppfinningen lOstagbart fast vid det yttre rOret, i det att den t. ex. kan vara ingangad I raret med gangor, vilkas stigning Or motsatt stigningen av rarets gangor. The formation itself, in order to fit the smallest possible dimensions, can suitably be made of a cone made of steel, in the cradle of which a spiral-shaped continuous slot, one side edge of which is bent and sharpened, so that it bites the knife of the former. That the knife goes helically, means that it slides'. Miter On the straight knives common for conical shapes. However, it is also possible to use a straight knife, which is embedded in the said manner or, as is usually the case with conical formers, a steel knife, which is screwed to the edge of the pliers by a slot in the cone. The former Or according to the invention is removably attached to the outer tube, in that it e.g. may be entered in the ridge with passages, the pitch of which is Or opposite the pitch of the ridge corridors.

Utvandigt ph det yttre roret kan lampligen liistas en riled botten forsedd hylsa, som omfattar formeraren, sa att hole hallaren far en idealisk glatt cylindrisk form. Hylsan tjanar dessutorn till att under formerandet upptaga span, som kunna avlagsnas da och da. On the outside of the outer tube, a riled bottom-mounted sleeve, which comprises the former, can suitably be attached, so that the hole holder has an ideally smooth cylindrical shape. The sleeve also serves to absorb spans during formation, which can be removed from time to time.

:A bifogade ritning visas ett utforingsexem- pel pa en blyertshallare e:nligt uppfinningen. The accompanying drawing shows an exemplary embodiment of a pencil holder according to the invention.

A ritningen betecknar 1 det inre roret med fasthallningsanordning for blyertsen. Denna anordning bestar vid det visade exemplet av fliken eller haken 2, som bojes in sh att de fjadra och darigenom fasthalla blyertsen i rOret. Man kan emellertid anvanda fasthall- ningsanordningar av godtyckligt slag. I sin nedre del Or rOret I forsett med gangor 3. In the drawing, 1 denotes the inner tube with holding device for the pencil. This device consists in the example shown of the flap or hook 2, which is bent in sh that they spring and thereby hold the pencil in the tube. However, restraint devices of any kind can be used. In its lower part Or rOret I continue with gangor 3.

Dot yttre rOret Or betecknat med 4. Detta har ph en del av sin langd hrvandiga gangor 5, med vilka gangorna 3 ph rOret 1 komma ingrepp, nar roren Rims in 1 varandra. I sin nedre ande har rOret 4 invandiga gangor 6, I vilka formeraren 7 inskruvas. Dessa gangor have stigning Ot motsatt hall mot gangorna 3 och 5. floret 4 har dessutom utvandiga gangor 8 for paskruvande av hylsan 9. The outer tube Or is denoted by 4. This has ph a part of its length hrvarandi corridors 5, with which the passages 3 ph the tube 1 come into engagement when the tubes rim in 1 each other. In its lower spirit, the tube 4 has internal passages 6, into which the former 7 is screwed. These passages have a slope ot opposite the hall to the passages 3 and 5. the floor 4 also has external passages 8 for screwing on the sleeve 9.

Formeraren 7 Or i sin koniska vagg forsedd med en spiralformigt lopande slits 10, vars ena sidokant Or bojd inat sa, att den bildar kniven. The former 7 Or in its conical cradle is provided with a helically extending slot 10, one side edge of which is bent inwards so as to form the knife.

Nar blyertsen skall spetsas, fores roret 1 in i rOret 2, tills gangorna 3 och 5 nastan komma i ingrepp med varandra. Blyertsen inskjutes darpa sa langt in i rOret 1, att dess spots kommer att ligga an mot formeraren. Darpa vridas roren i farhallande till varandra, och da blycrtsen fasthalles i roret 1 nedfores den automatiskt, sa att den formeras, i det den harunder far god styrning, genorn att rOret 1 styres inne i rOret 4. Frarnmatningen sker sa lange som gangorna 3 oar 5 sia i ingrepp med varandra, men upphor automatiskt, nar gangorna 3 Oro helt och hallet skruvade geHorn gangorna 5. Nar blyertsen skall anyandas, tages den ut ur rOret 1 och insattes med spetsen vand utat. When the pencil is to be pointed, the tube 1 is inserted into the tube 2, until the passages 3 and 5 almost come into engagement with each other. The pencil is inserted darpa so far into the tube 1 that its spots will abut the former. Then the tubes are rotated in relation to each other, and when the lead is held in the tube 1 it is lowered automatically, so that it is formed, while it has good control, so that the tube 1 is guided inside the tube 4. The feeding takes place as long as the passages 3 oar 5 sia in engagement with each other, but ceases automatically when the passages 3 Oro completely and the hall screwed geHorn the passages 5. When the pencil is to be used, it is taken out of the tube 1 and inserted with the tip water out.

Det sift, pa vilket sjalva formeraren Or fast ph Oct yttre roret, mojliggor att formeraren kan utf ores i ungef Or tva likadana delar, som upptill hallas &Inman, darigenom att de omfattas av rOret, och nedtill sammanhallas de med hjalp av en ring eller mutter. En dylik uppdelning av formeraren Or synnerligen for- — — delaktig vid framstallning och senare slipning av dess skarande egg. The sieve on which the former itself forms the outer tube, allows the former to be made in approximately two identical parts, which are held at the top & inman, in that they are covered by the tube, and at the bottom they are held together by means of a ring or nut. . Such a division of the former Or is particularly advantageous in the production and later grinding of its cutting edge.

For att man mera bekvamt skall kunna om blyertshallaren kan derma vara utvandigt forsedd med rafflor, exempelvis pa den ovre koniska delen av roret 1 och pa en del av hylsan 9. In order to be more comfortable about the pencil holder, it can be externally provided with grooves, for example on the upper conical part of the tube 1 and on a part of the sleeve 9.
