Abstract

149,072. Marks, E. C. R., (American Lead Pencil Co.). May 7, 1919. Pencils.-Pencil leads and similar material are formed as plastic rods by extrusion through orifices, and are then delivered upon a carrier and subjected to heat or other drying agent, the carrier being provided with means for straightening or preserving the straightness of the rods while drying. Fig. 7 shows an extrusion device producing several rods 23 from a thick ribbon 24 at each stroke of a plunger 21. The ribbon 24 is fed intermittently across the path of the plunger to an extent determined by a spring-projected supporting-lever 27, which is tripped by a projection 32 on the plunger 21, and is angularly adjustable to regulate the feed. The extruded rods 23 are received in grooves 45, Fig. 4, in a transferring- cylinder 44, which is advanced intermittently by pawl-and-ratchet mechanism, and delivers the rods over the end of a shield 58 to a transverse carrier on which the rods are dried. The rods are cut off adjacent to the orifices by the, edges of the grooves 45, and are preferably made long enough to project at the other end of the cylinder 44 for trimming by a stationary knife. The transverse carrier may be grooved to receive the rods and advanced intermittently. In the arrangement shown in Figs. 4 and 8 the transverse carrier comprises three conveyer bands 65, 66, 67, preferably of absorbent material, running over heated tables 59, 60, 61. A preliminary drying under close confinement is given on the table 59 under a band 80, and subsequently on the tables 60, 61 the rods are exposed to the open air. The bands 65, 80 may be run at different speeds to give slow continuous rotation to the rods. On the tables 60, 61 intermittent rotation is imparted to the rods by means of friction bands 85, which are fixed at their forward ends and lie loosely on the conveyer bands. The bands 85 are preferably loaded at intervals by means of slats attached to their upper surfaces. The tables are disposed at different levels so that the rods fall a short distance from one table to the next, to corect small divergencies from parallelism. The dried rods are discharged upon a delivery band 88, on which the ends of the rods are trimmed by knife-edge disks 92; horizontal disks 98 aline the rods on the band 67 in relation to the cutting-disks. Reference is made to Specification 143,073.
