Title: Improvements in door-closing devices
IPC: E05F1/10
Filed: 1934-06-11
Abstract: 421,037. Door-operating appliances. DILLEN, A. VAN, 83, Beethovenstrasse, Amsterdam. June 11, 1934, No. 17242. [Class 65 (i)] A device for completing the closing of a door comprises a doublearmed spring-controlled lever mounted on the door and co-operating with coupling means on the door, so arranged that the lever is released from the coupling means after being deflected at the commencement of opening of the door and remains in position for re-engagement on closing the door, the spring then coming into operation to complete the closing and to hold the door firmly closed ; a blade or like spring, arranged in the plane of the lever, is used, and this bears against the lever either directly or through the intermediary of another lever. The form shown is applicable to a door opening in either direction ; a forked lever 4, pivoted at 18 in a casing in the door frame so as to swing in a plane at right angles to that of the doorway, engages a roller 10 on a stud carried by the door, and is acted on by two strip springs 5 each fixed at one end in the casing and bearing at the other on a pivoted lever 11 which bears against the upper end of the lever 4. When the door is opened, the lever 4 is deflected to the position shown dotted and the roller 10 then leaves the fork of the lever, which is retained in the position shown by the lever 11 pressing on the upper end of the lever 4 in a direction passing through the pivot 18 ; the other lever 11 meets a stop 13. When the door is closed again, the roller 10 re-engages the fork of the lever 4 and moves it towards the vertical position, so that the pressure of the lover 11 becomes effective to continue the motion of the lever 4 and complete the closing of the door. The pivoted levers 11 may be replaced by blade springs; in a modification, they are not used, the ends of the springs 5 bearing directly on the lever 4. In a modified form for use with doors opening in one direction only, the forked lever 4 is replaced by a straight lever which engages between a pair of rollers carried on a bracket on the face of the door.

Abstract: 391,636. Boxes for cigars &c. BRADEN, W. E., 28, Reed Pond Walk, Gidea Park, Essex. June 20, 1932, No. 17397. [Class 18.] A box or case for cigars &c. is of substantially cylindrical shape with radial vanes or fins which are movable one towards the other or towards a fixed partition to maintain the contents compactly in a vertical position after a part has been withdrawn. As shown the box a has a diametral partition c secured to a rod d secured at its lower end to a false bottom e and two vanes g, g<l> hinged to the rod d are forced by springs i towards the partition to hold the cigars &c. b in the vertical position. The partition may have lugs f by which it is secured to the bottom e which may be concave, convex or stepped so that the ends of the cigars &c. are at different levels to facilitate withdrawal thereof, or at the same level if the cigars &c. are of varying lengths. The bottom of the box or the bottom e may have serrations or notches with which the lower edges of the vanes or projections thereon engage to prevent backward movement of the vanes and, in this case, the springs i may be dispensed with. The upper end of the rod d is formed as or provided with a handle or ring by which the bottom e and the contents of the box may be raised in, or withdrawn from, the box ; the bottom may be hinged to the partition and may be in two parts. In a modification a fixed and a movable vane may be carried by each of two rods secured to the false bottom parallel to each other with the upper ends of the rods connected to form a handle.
