Card Punch

This card punch serves to punch holes of a uniform code into a punch card. It may be strapped, for example, to the arm of a patient and be used to identify specimens taken from him. When a specimen is taken the patient's code is punched into a punch card, which is then affixed to the container of the specimen. Free fields in the punch card can be employed for further data.

The card punch measuring abt. 35 x 30 x 10 mm consists of a base 1 and a lid 2, which are connected by means of a hinge 9. 0n its sides base 1 is provided with four adjusting points 3. These points 3 are arranged unsymmetrically, to prevent cards punched in the places where adjusting points 3 are positioned from being erroneously inserted. Bores 4 between the adjusting points are arranged so as to suit the code used. Lid 3 comprises recesses 5 facing adjusting points 3 in the base. Lid 2 also incorporates two leaf springs 6, the free ends of which are disposed between adjusting points 3 and recesses 5. Leaf springs 6 have a longitudinal slot 7 extending across the full area of adjusting points 3. Punches 8 in lid 2 match bores 4 in base 1. The various code elements with bores 4 and punches 8, which can be made readable by an imprinted digit, are preferably exchangeable.

Full punching, lid 2 of the card punch is opened and the punch card is placed on adjusting points 3. By partly closing the lid, leaf springs 6 are caused to descend so that the punch card is forced against the base. T...
