Abstract

410,426. Photographic roll-film spools. SCHWARZ, P., 3, Diekerstrasse, Wichling- hausen, Wuppertal, Germany. Dec. 1, 1933, No. 33839. [Class 98 (i).] In an all-metal spool, the winding- key slot is provided, at the edge of the middle enlarged portion, with a drawn guide neck formed with two oppositely located longitudinal slots and having a length approximately equal to or greater than the diameter of the middle slot portion. As shown, the end disc b, secured to the tube a by a fold c, has a key slot d provided with a guide neck f extending inwardly into the tube a and formed with two longitudinal slots g located at the points at which the narrow end portions d<1> of the slot d commence. At one edge each slot g is provided with an outwardly extending lug h. The bottom of the guide neck may be punched out or perforated and bent outwards to form an extension of the guide neck. In a modification, the two halves of the guide neck separated by the longitudinal slots are connected at the inner ends by means of a transverse web. The guide lugs may be provided on both the edges of the longitudinal slots. The spools may have flanges consisting of several parts, and the guide neck may be made as a separate part.
