Propelling pencil for pins, whether coloured or not, which consists mainly of the combination of an elongated casing (1) with an axial bore (2) for housing a pencil pin (3) which is provided at the top with a screw thread part (6), a screw head (9) with an axial bore for passing thepin (3) and of which the tailpiece (13) is provided with a screw thread part (12) which can be screwed into and moved in the screw thread part (6) of the axial bore (2) of the casing (1), the tailpiece (13) being provided with several longitudinal grooves (14) which run over a distance of the end of the tailpiece, and means (7-15) being provided for gradually squeezing the middle part of the tailpiece (13) in which the grooves are provided, between the axial bore (2) of the casing (1) and the tailpiece (13) of the screw head (9).
摘要:
This application discloses multi-color marking implements (i.e. crayons) having variegated color patterns, and a method and apparatus for their manufacture involving consecutively casting small amounts of molten crayon-like materials into suitably shaped molds at specific temperatures. The marking implements have a multiplicity of discretely-colored regions of random shape, randomly distributed in the implement. In addition, the marking implement may include a multiplicity of non-discretely colored regions resulting from a blending of colors from two discretely-colored regions. Optionally, the multi-color implement may be provided in a transparent lipstick type container that may serve as the mold in the casting process.
