Abstract
238,884. Engstr÷m, D. A. Aug. 23, 1924, [Convention date]. Endless and continuous band files; cards. - The cards of a card register are secured together so as to form a continuous band capable of being made into a roll and wound from one roller to another on shafts mounted in a casing, inspection and marking of the cards being allowed by an opening in the top of the casing. The cards may be secured together by the provision on the edges of interlocking tongues 1 and holes 2, or by connecting the cards together by means of staples. Alternatively, the edges of the cards are inserted in flexible bands formed, preferably, of elastic strips united at their outer edges and connected by transverse stripe. Slots 11, 12 are provided in the casing 10 to receive the shafts 6, 7 on which the bands are rolled, crank handles 8, 9 being provided thereon, together with a support 13 for the cards and an inspection opening 14 in the lid 16. Movement of the cards may be effected by a small electric motor, and devices may be provided for indicating when the required card is nearing the reading position. When the cards are made into a roll, this may be sealed and stored.
