It will be seen from the drawings that the covered wire or cable as it moves forward passes between the roller Il and the die roller 2l, and no driving mechanism is required for the entire vmachine other than the act of drawing the wire or cable through it.

Inasmuch as the platen Il, the lnking rollers and inking wheel are all adjustable in the frame 2, it will be quite apparent that the parts can be adjusted so as to provide the proper pressure between the faces of the various wheels and rollers and also so that the type or die on the i'ace of the type or die wheel 24 will bear wtih the proper pressure upon the cover or insulation Il of the cable 40 in order that the desired symbols, characters and other markings may be applied to this covering as the cable passes through the machine.

My machine will print coated wire while the coating is still soft and the-imprint will remain after being further coated with paraffin or wax coating. I might say, also, that my machine is adapted to print a paraffin or wax coated wire as well as a wire having cloth, fabric, rubber or other coating.

It is to be understood that changes may be made in the details of construction and arrangement of parts above described without departing from the spirit and scope of my invention.

What I claim is:

1. In a machine of the class described, the combination of a vertically extending supporting frame, a supporting block extending through the frame, compression springs beneath the block, an adjusting screw above the block for adjusting the compression springs,` a stub shaft extending through and supported by the block, a platen carried thereby, a compression spring intermediate the frame and said platen, said shaft being adjustable lengthwise to vary the spacing of the platen from the said supporting frame, and a thumb-nut for holding the shaft in adjusted position.

2. In a machine of the class described, the combination of a vertically extending supporting frame, a supporting block extending through the frame, and vertically slidable in guides therein, compression springs beneath the block, an

die wheel 24 and adjusting screw above the block for adjusting the compression springs, a stub shaft extending through and supported by the block, a platen roll freely rotatable thereon, a stub shaft above the first mentioned shaft extending parallel thereto, said last mentioned shaft being adjustable in an axial direction in said frame, and a type wheel freely rotatable on the last mentioned shaft with its periphery aligned with the periphery of the platen and spaced therefrom to provide for the reception of a traveling covered wire to be marked, the platen and typ'e wheel being constructed and arranged to retain a cable injalignment with said type wheel. i

3. A cable printing machine comprising a frame, a type wheel journaled for rotation around a continuous shaft and freely rotatable thereon, the type wheel and platen being so constructed and arranged thatthey are rotated by drawing the wire or cable through the machine, an inking roller resiliently bearing against said type and a platen wheel resiliently mounted for rotation adjacent to said type and constructed and arranged to bear against a strand of wire while the latter is in engagement with said type, said platen wheel having a V shaped periphery to retain the strand in alignment with the type and means for applying oil to the said poriphery.

4. A cable printing machine adapted to print on a cable having a wet coating thereon comprising a stub shaft, a type whel mounted for free rotation upon.said shaft and having a grooved line of type thereon, means for applying ink to said type, a second stub shaft parallel to said rst mentioned shaft, a grooved platen mounted for free rotation upon said second shaft, said shafts being so spaced as to bring said platen into alignment with and in spaced relation to said type wheel, means for adjustably varying the spaced relation of said wheels whereby the printing pressure may be accurately determined independent of other factors, said parts being so conment of the cable between them in contact with the type and means for continuously applying a lm of oil to said platen to protect said wet coating from damage.
