Abstract: 146,109. Addressograph, Ltd., (Assignees of Duncan, J. S., and Hubbard, H. E.). June 23, 1919, [Convention date]. Void [Published under Sect. 91 of the Act]. Addressing-machines.-An addressing machine is fitted with an attachment for feeding through the machine ruled or plain sheets on which names or addresses can be printed in list form. This feed mechanism is automatically actuated by the platen-operating means, but is capable of independent operation, and the feed rollers can be tripped when desired, and the extent of the feed motion can be varied as desired, and is so governed that the motion is slow at the commencement and finish of each operation. As shown in Fig. 1, the feeding-device is mounted in a frame 20 which is attached by means of a pin 22 and set-screw 21 to the frame 10 of the addressing-machine. The platen 13 of this machine is operated by hand to depress it to printing position against the action of a spring which normally maintains the arms 14 of the platen in a raised position. When used for listing, the strip or sheet is guided transversely by an adjustable guide 57 carried by rods 58 from the frame 20, and the strip is advanced after the printing operation by means of rollers 24, 33, Figs. 4 and 5, which are operated by means of a long flexible shaft 23, fitted with a gear wheel 34 which is oscillated by a rocking toothed sector 36 operated from the platen mechanism by means of a link 38 and an adjustable crank mechanism. The wheel 34 drives the shaft 23 through a roller clutch 25 which operates this shaft only during the return movement of the platen. The roller 24 is mounted in a bell-crank 25, 25<1>, normally maintained in operative position by a spring 28, Fig. 5, but capable of being moved by a cam-shaft 27 fitted with a lever 29 to raise the roller 24 out of action, the shaft 23 being formed long and thin to permit its flexing to enable this to be done. The roller 24 can be operated by a hand-wheel 23' for adjustment purposes. The crank-mechanism for oscillating the rocker 36 comprises a block 41 fixed on a horizontal shaft 42, and fitted with a sliding block 44 integral with a nut 40 which is adjustable by means of a screw 45 with a cap 46 to permit the radial distance of a crank-pin 39 from the axis of shaft 42 to be varied. Scale pointers are provided to enable the feed to be adjusted as desired. The pin 39 is connected by a link 38 to the rocker 36, and the shaft 42 is oscillated from the platen by means of a lever 47 and link 48, and a rocking member 49 which is actuated by a pin 55 on the platen arm and is capable also of hand manipulation. The rocker 49 is normally maintained by a spring 54 at a spaced distance from a second pivoted member which moves with the rocker and is fitted with a shock absorbing spring. The pin 55 acts on this second arm on the return motion of arm 14, and the rocker 49 is in this case operated from the second pivoted member by means of the spring 54. After being printed the sheet is guided by curved arms 60 connected by bars 61, 62, and mounted in a frame which is secured in position by a set-screw. The platen may be constructed to print from the whole or a part only of the printing plate.
