Abstract: 492,891. Stapling. QUICK. C. G., and FOWLES, R. W. Feb. 26, 1937, No. 5849. [Class 89 (iii)] A rotary web-stapling mechanism designed for inserting a line of staples longitudinally of the web feed comprises staple-forming, stapledriving, and clenching cylinders 1, 2, 3 and a wire-feeding mechanism M. The cylinder 1 comprises two plungers 7, 8 which are projected in turn, at an appropriate time, beyond the periphery of the cylinder, by levers 11, 12 connected by a link 17 and operated by a cam projection 24 and a recess 25 in a fixed ring 22. When so projected, each plunger co-operates with a recess 28 or 29 in the cylinder 2 to bend into staple form a length of wire 38 which has been fed between the cylinders. The formed staple is carried round by the cylinder 2 until it registers with one of two clenching blocks 45 provided'in the cylinder 3. At this point, while the staple, the webs W to be stapled, and the block 45 are, relatively, at rest, the staple is driven through the webs by a plunger 26 or 27 movable in the recesses 28, 29 and operated by cam linkage similar to that for the plungers 7, 8. This cam operation is such as to produce a very rapid projection and retraction of the plungers. The wire-feeding mechanism comprises a ratchet and pawl 30<1>, 32 operated by a crank disc 35, and staple lengths are severed by a cutter 42, Fig. 4, which is carried by a pivoted arm 40 and is operated by tappets 44 adjustable on the cylinder 1.

A magazine for double-run 8mm. cine film has a feeler arm 15 fixed to pivotable pin 16 and spring- urged into contact with the film on the take-up reel 14 until a certain diameter is reached when a projection 19 on the arm enters a recess on the inner wall 20, the pin 16 then being moved axially under the action of a pin 7 on contact spring 27 whereby the contacts 26, 27 are opened and the camera motor is switched off. Magazine 8 is then turned over so that the reel 13 is mounted on the driving pin and a further lug 18 now enters a shallow recess 23 which retains the arm 15 but does not permit the contacts 26, 27 to open; braking of the supply reel is thus avoided. After the second run, the film is allowed to run off the spool 14. As a safeguard against wrong insertion of the magazine, recess 24 is provided to engage lug 18 and switch off the motor. A centrifugal switch controls the motor speed, and the invention may be applied to spring motor cameras.
