[Class 97 (i).] Strips such as kinematograph films are attached to spools by a device which is adapted, by manipulation from outside the spool discs, to be moved towards the periphery so that the strip may be attached thereto, and then to be moved into the interior of the core, the core being hollow. Fig. 2 shows a film clamp 6 between the spool discs 3 which is formed by bending the end of an arm 5, extending through an arcuate slot 7, and mounted on a pivot 4, outside the discs, at the centre of the arc. The core comprises a cylindrical jacket 2, riveted to the discs 3, and having an aperture 8 to permit the clamp 6, after the film 10 has been attached to it while it is at the periphery of the discs, to pass into the core. The position of the pivot 4 &c. may be such that the clamp 6 is urged towards the core when winding is begun, and the arm may be located on the side of the spool adjacent to the operator when the spool is correctly mounted in the apparatus. The spool discs may be formed without large apertures therein. The Specification as open to inspection under Sect. 91 (3) (a) describes also a construction wherein a clamp to which the strip is attached is secured to the end of a strip or band spring which can be rolled up on the core and pulled out therefrom for attachment of the film, and also constructions comprising other forms of clamping means. As shown in Fig. 5 (Cancelled), a clamping device 9 in the form of a resilient U-shaped metal strip is provided with a projection which passes through a radial slot 71 in a spool disc, and terminates in a knob by which it is movable along the slot so as to clamp a film strip between it and the edges of an aperture in the spool core 2. The clamp 9 may have a rough surface to prevent the film from being pulled out, and resilient means may be provided enabling the clamp to be retained in any desired position. A clamping device similar to that shown in Fig. 5 (Cancelled) may be carried on an arm pivoted as shown in Fig. 2. Fig 7 (Cancelled) shows a pressing piece 14 curved to conform to the surface of the spool core and having a roughened surface 15 ; the piece 14 may be carried by an arm 5 pivoted on one disc and pressed by a spring 16, or by duplicate arms and springs pivoted one on each disc. The piece 14 and the arms may be made from a single thick wire, and the piece 14 may then be received in a recess or groove in the spool core. This subject-matter does not appear in the Specification as accepted.

Patent GB-384161-A (GB)
Title: Improvements in or relating to mercury dash-pot timing devices
IPC: G04F1/00
Filed: 1932-03-30
Abstract: 384,161. Dashpots ; retarding electric switches. IGRANIC ELECTRIC CO., Ltd., 147, Queen Victoria Street, London.-(Assignees of Schmidt, E. X. ; Whitefish Bay, and Stevens, W. C. ; Milwaukee, both in Wisconsin, U.S.A.) March 30, 1932, No. 9135. Convention date, March 30, 1931. [Class 108 (iii).] In a mercury dashpot timing device, applicable to switches, a cup or cylinder and its close fitting piston are formed of a rigid composition comprising graphite and a non-metallic bonding material such as the material sold under the Registered Trade Mark Bakelite. The dashpot, Fig. 1, may be associated, as shown in Fig. 4, with switch operating mechanism whereby a period of slow movement is followed by a rapid closing movement. The dashpot cylinder 10 is bolted to the underside of a metal casting 23 which may be secured to an insulating panel 72. As the piston 11 moves up or down, mercury is transferred through the byepass 15, 16 which is regulated by an adjustable pin 30. Within the body of the piston 11 is secured by a nut 43, a metal bushing 37, the upper flange of which bears on an upstanding flange on the body of the piston, providing an annular recess 40 into which a number of vertical passages 41 open. The recess 40 is further connected to passages 44 which may be closed by a disc 45 slidable on the piston-rod 51 and pressed down by a spring 46. The piston is operated from a spindle 61 through the piston-rod 51 which is movable relatively to the piston under the control of springs 53, 46 and carries at its lower end a ball valve 49. When the piston is forced downwards by the piston-rod, the disc 45 closes the ports 44 and the ball valve 49 is forced on to its seat, thus closing the central openings. The rate of movement is then slow since mercury can only flow through the byepass 15, 16. When the disc 45 is stopped by a shoulder on the cylinder 10, the piston moves downward rapidly since the ports 44 are then uncovered and mercury can flow upwards freely. On the upward return movement, the valve 49 is lifted off its seat and mercury can flow freely downward through the central passage. The shaft 93 may be operated in a clockwise direction to close contacts providing starting connections for an electric motor, while contacts 69, 70 are closed to complete the running connections of the motor after a period depending upon the dashpot. The shaft carries an arm 86 connocted by a link 83 and spring 89 to a lever 78 secured to the spindle 61 operating the dashpot. The lever 78 also carries a plate 81 which closes the contacts 69, 70 sharply when allowed to do so by the dashpot. When the shaft 93 is rotated, the spring 89 is extended and the link 83 slides through the block 85 on the lever 86. The spring 89 rotates the spindle 61 and moves the dashpot piston downwards slowly until the point is reached when the piston is allowed to move freely and the contacts 69, 70 are then closed quickly.
