350,387. Ornamenting pencils. ANGLO PENCIL CO., SMITH, M., and PRITCHETT, R., Bank Chambers, Pelham Street, Nottingham. March 5, 1930, No. 7167. [Classes 93 and 146 (iii).] Pencils and like articles are ornamented by providing the surface with a sensitized coating, and passing the articles in succession through an apparatus for exposure under a negative, the prints being subsequently developed and fixed, and toned if desired. A matt surface of pigmentized cellulose ester and gelatine varnish may be provided as an undercoating on which the gelatine or collodion sensitizing emulsion is applied. Finally a coating of nitro-cellulose varnish is applied to protect. the print. In the apparatus shown, the pencils 2 are fed from a hopper 8 by means of a plunger 3 reciprocated by solenoids 4, 5 alternately energized when a brush member 19 contacts with contact elements 20, 21 mounted on a rotating drum. The pencil is pushed from the hopper 8 between oppositely-rotating feed-rollers 9 into the printing- chamber 10, and a negative 12 is brought down into contact therewith by the action of solenoids 14, the circuit being completed by the brush 19 and a strip 22 on the drum. Further rotation of the drum causes the member 19 to make contact with a strip 23, thereby lighting a lamp 16 to make the exposure. Subsequently the brush moves out of contact with the strips 23, 22, thus permitting the negative to move upwards under spring action, and the exposed pencil is ejected by the incoming pencil. Mechanical means may be substituted for the electrical means described. Dipping-machines such as are described in Specification 325,638, [Class 95, Paints &c.], may be used for applying the sensitized emulsion, and for developing and fixing.
