Abstract
831,632. Propelling pencils. KREUTZER, R., and WISSMULLER, G., [trading as STAEDTLER, J. S., [Firm of]]. Dec. 24, 1957 [Dec. 24, 1956], No. 40112/57. Class 146(3) A longitudinally slit lead gripping device for pencils for holding leads of different thicknesses has a frusto-conical outer surface which is stepped in such a manner that any one of the steps can co-operate with the forward part of the pencil depending upon the thickness of the lead. The gripping device b has a cylindrical rear portion threaded at c for connection with a lead guiding tube or the like and which is inserted in a corresponding bore in the point section a of the pencil. The bore is enlarged at the outer end of the point section to receive the enlarged portion of the gripping device which is formed with three annular steps f 1 , f 2 , f 3 . ...The device has a number of longitudinal slots d to form a corresponding number of gripping jaws. The diameter of the bore of the head part e of the device is variable to accommodate leads of different thicknesses, being at its smallest when the step f is inserted in the enlarged bore of the point section and at its largest when only the step f 3 is inserted.
