I The present invention isdirected to an imiprovement in punch ing devices :for lpunching tabulating cards. I V

Inthe-makmg of these cards-for dlrectory 'work'ithasbecome the practice to codet-he alphabet. and utilize multiple punchings to The punching of uiresa coninarily it is perform the cod-mg operation mentall and then to strike the proper combination 0 keys to accord with thencoded character. In lizing combinational holes for denoting :siderable amount of skill as or phabetical *characters the machine itself effects-the coding but the actual punching operation is effected by the power of the operators fingers.

The present invention is directed to the provision of a simplejpunching device WhlCh is adapted to be controlled by a keyboard similar to that used on in which the coding. of the characters is effected automatically by the machine and in which the direct labor of-punching. is-performed by the machine itself instead of by the operator as heretofore.

According to the presentinvention the operator. strikesthe usual typewriterform of keys. The operation of these keys effects the selection of the desired combinations of punches and thereafter-thepunch tion itself is performed'by the rived from a translating device in ing operapower dethe punchmerelydepresses the keys for controlling and selecting purposes and all other operations are per formed automatically by the-machine. Ac-

cording to the present invention the only effort required upon the part of the'operator is the effort required to close a single pair of contacts associated with each key and all the other I operations are performed automatically and by an outside source of power. Furtherobjects and advantages of the present invention will be hereinafter set forth in the accompanying specification and claims and shown in the'drawings which by wayof illustration other devices utiq moved position.

F 1g. 7 is a circuit diagram of the machine. The machine in general includes a keyboard section designated A and a punching section designated B. The punching section 'inits general characteristics is similar to devices already in use. usualelectric key punch previously utilized for punching the tabulating cards. The particularform herein used is more fully shown and described in the copending application ,of John T. Schaaii, Serial vNo. 731,980, filed August 14,1924. A somewhat similar form is shown in the-patent ofL. C. Reynolds No. 1,298,400. The punching attachment includes the usual mechanismjfor feeding the The principle of operation utilized with punches of this character is to a plurality ofpunches 20 disposed across the punching attachment, .each punch corresponding to a particular indexpoint perforation in the card. In the present embodiment twelve such .punchesare provided. In the operation .of the punching attachment a punching operation is eflectedupon one col- 'umnof the card, then the .card is displaced relatively to the punches and a second punching operation is performed in another column on the card. The arrangement of the parts is such that feed of the card takes place 7 I The card feed is usually effected by means of a spring It consists of the.
