953,229. Selective embossing machines. ADDRESSOGRAPH-MULTIGRAPH CORPORATION. May 1, 1961 [June 27, 1960], No. 15672/61. Heading B6F. In a machine having a rotatable head carrying punches and dies for embossing character- &c. on plates P, Fig. 11, and which can be keys operated or controlled for all operations, including feeding and delivering the plates, by perforated tape the punches and dies are certain circumferential positions are formed to emboss a stylized numeral NC and a corresponding code marking CR, whilst others emboss a normal character AC, ON, and the machine is provided with means whereby when the carriage is positioned for embossing the line containing normal characters, operation of the stylized and code punches and dies is prevented. The plates P are intended to be used for printing on record sheets, tabulating cards &c., which are to be scanned for accounting purposes, the code marking being printed in an magnetic ink. The punch and die 27B, 28B, Fig. 8, for each numeral NC and code marking CR is a single element, and such elements are spaced around the periphery of the head with groups of the punches and dies 27A, 28A for the normal in characters between them. The positioning of the head for embossing particular markings is effected by stops 50 connected to key bars 51. Certain of the normal character dies, however, carry shift characters, i.e. numerals or lower case characters, and to position these deis, an additional movement of the head corresponding to the circumferential distance between two normal dies is effected as follows:-the head has two teeth 45T at its lower face engaging two inclined slots 42R in a collar 42 splined to the driving shaft 40, and raised or lowered into one of two positions by an arm 70 attached to a rockshaft 73. The lower position shown in Fig. 8 is the shift position wherein a stop 50 will select a shift character, but if the collar 42 is raised, the head is given the additional movement mentioned, and a stop 50 will select a non-shift character or a stylized numeral. The carriage 65, Fig. 11, has jaws 66 holding the plate P, and is line-spaced by a rack-and-pinion mechanism 90, 92. When the card is positioned for the embossing of the " line " of numeral and code markings NC, CR, a cam member 94 on the shaft 93 operates a two-way switch 100 to energize an electromagnet 81, Fig. 9, which causes a lever 88 to move clockwise, this preventing any shaft movement as described later. When the carriage 65 moves to
