Stapling, hand tools for.-In a stapling machine of the desk type using loose staples which are fed along a bar by a spring pusher, the end staple 73, Fig. 4, is supported before, and during most of, the driving stroke of the driver 52 bv a spring strip 54 having an inturned lower end 58. The strip 54 moves downwardly with the driver untilstopped by the engagement of a stop 60 with a front plate 55, after which the driver completes its stroke alone, pushing the strip outwardly from the staple. The staple bar 21 and casing 19, 28 are pivoted to the base 16 at 20. The staples are fed by a pusher 27 connected by a flexible strip 37 to a drum 30 adapted to be rotated about an axis 31 in a counter-clockwise direction by a spring 36 mounted within it. An open side of the drum is closed by a disc 32 pinned to a sleeve 34 on the axis 31 to which one end of the spring is connected. The disc, which is free to rotate independently of the drum. has mounted on it a ratchet 41 and is normally held from rotation by a spring-held pawl 44. The pawl is lifted from the ratchet at each up and down movement of the driving plunger 39 by a bar 49 on the plunger engaging cam faces 48 on an arm 47 of the pawl, thus allowing the spring 36 to pull forwardly the pusher 27. The disc 32 carries an arm 63 projecting into a slot in the plunger 39 so that the downward movement of the plunger rotates the disc and increases the tension of the spring 36. The arm 63 is raised by a spring 65 to raise the plunger 39 after its stroke. The spring 36 and its associated feeding parts are mounted as a unit in a casing 29 which can be put in place in the machine by moving a cover plate of the casing 28. In replenishing the supply of staples. the pusher 27 is pulled out backwardly, the pawl and ratchet preventing return motion of the spring.

Filed: 1974-03-08
Abstract: 1468967 Collapsible containers W ZARGES 8 March 1974 [9 March 1973] 10594/74 Heading B8P  In a collapsible container comprising a base tray 1, pivotal side walls 2-5 having pins 6 and 7 engaging in vertical slots 8 and 9 in the sides of the base tray to facilitate inwards collapse of the side walls on to the base of the tray, and a removable top cover 10 lockable by commonlyactuated bolts 12-15, the slots receiving the pins of the front side wall 2 are spaced inwardly of the corresponding tray front wall 33 to form a space 32 between these walls which accommodates locking means associated with one or more closures 21 and 25 of openings in the tray bottom. The arrangement is such that the closures cannot be opened until the top cover is released thus permitting the use of only one lead seal to seal the top cover. As shown, a downwardly-opening pivotal flap 21 is lockably retained by a hooked lever 46, which is pivoted to the tray by a bearing 47, having an opening key receiving square bore 50. This bore may be blocked during container transit by a protrusion 53 on a loosely-pivoted plate 51 such that this protrusion can only be pushed inwards out of the bore to permit unlatching of the flap when the front side wall is raised. In a modification, Figs. 7-9 (not shown), the plate 51 being pivoted aside in use to leave the bore 50 clear, the hooked lever is coupled by a cable (56) to a pivoted lever (57), which is engaged by the bolt (12) of the cover so that the hooked lever can only be released on retraction of the bolt (12). A further, upwardly and inwardly openable flap 25, Fig. 6, in the tray bottom has a pivotal free edge locking portion 31, which is received in the space 32 and which can only be pivoted inwardly to clear a stop 36 to allow opening of the flap when the front side wall is raised. This arrangement is for use with a lining bag since the flap 25 has to be opened before the container is filled. In another modification, Fig. 10 (not shown), the flap 25 is replaced by a horizontally-pivotal cover plate (20), which cannot be opened until the flap (21) is opened. The base has openings 17 and 19, Fig. 1, in a support skirt for receiving the tines of a forklift truck and an opening 23 for receiving the outlet pipe of a lining bag for carrying liquids in the container. Encodable magnets or magnetic strips (67), Fig. 3 (not shown), may be provided on the inner side of the base tray front wall (33) to facilitate automatic direction of the container to a conveying vehicle and a destination strip or label may be adhered to, or received in a recess (34<SP>1</SP>) in the outer side of the tray wall (33).
