Title: Improvements relating to Clip Applications
IPC: B65B51/04
Filed: 1968-11-04
Abstract: 1,187,737. Sealing apparatus. SOC. FRANCAISE D'AGRAFAGE INDUSTRIEL. 4 Nov., 1968 [7 Nov., 1967], No. 52117/68. Heading B6P. A fluid cylinder operated sealing clip applicator is provided with a locking device which secures a sliding member (to which the sealing jaws are connected) to the piston-rod for the return stroke of the piston, in order to permit the jaws to grip a new clip supplied by a loader, the sliding member and the jaws subsequently being returned to clip applying position relative to the piston-rod by fluid pressure after the locking device is released. To apply a clip around, for example, the neck of a log, a fluid pressure valve in the handle of the applicator, is actuated by depressing a button 6. This places a channel 9 under pressure and evacuates a channel 10, which pushes the piston 12 forward from the position shown in Fig. 1. The piston-rod 14 penetrates a sleeve 18 so that an extension 33 on the rod 14 penetrates an extension 36 of the sleeve 18, thus pushing back a projection 37 which allows locking pins 35 to enter a groove 34 on the extension 33. A sleeve 39, repelled by a spring 40, ensures that the rod 14 and the sleeve 18 are locked by the pins 35. At this moment the end 17 of the sleeve 18 abuts against a washer 16 of the piston 12. The entire piston, shaft and sleeve assembly continues to move, thereby effecting the closure of the jaws to apply the sealing clip. When the push-button 6 is released, the channel 10 is placed under pressure and the channel 9 evacuated whereby the piston 12 draws back the jaws and the sleeve 18. After travelling a given distance, the rear end 44 of the sleeve 39 abuts the forward face of a bush 23, so that the pins 35 are unlocked. The sleeve 18 is checked but the piston and rod 14 continue to move back. At this moment the jaws (48), which are held open, stop opposite the loader (57, Fig. 2). Thereafter, the sleeve 18, which is free to move, is pushed forward under the influence of the compressed air which is contained in the cylinder 11 in front of the piston 12. In so doing the new clip deposited by the loader, is picked up by the jaws which move forward into their starting position. The loader (57) comprises a generally U-shaped cross-section channel with a spring- loaded follower (70) positioned behind a stack of sealing clips. Specification 972,489 is referred to.

Abstract: 1333964 Screw-threading and beading caps by rolling ALLUMINIO MAUCERI BORGHETTO SpA 11 Nov 1971 [11 Nov 1970] 52380/71 Headings B3A and B3E A head for a beading and/or screw-threading machine for metal stoppering caps on containers having a pouring mouth comprises a rotary body 1 adapted to rotate a body 5 coaxial therewith which is caused to slide axially with respect to the rotary body against the bias of a spring through the action exerted by applying the cap to the container mouth, the coaxial body 5 carrying beading and/or screw-threading members formed by respective levers 21, 23 fulcrummed on the coaxial body, camming means rotatable with said rotary body and axially slidable thereon against the bias of resilient means 50 which thrust them into engagement with the levers, said camming means comprising as many cam sectors 45 as there are levers to be controlled and every one of the cam sectors being thrust into engagement with the respective one of said levers by resilient means 50 which are individually adjustable. A motor (not shown) controls rotation of sheave 2 and simultaneous depression of the machine head towards the mouth of a stoppered container. Rotation of sheave 2 causes rotation of rotary body 1, of rotary body 5, and annular body 8 with its assembly of levers 21, 23 and respective rollers 28, 35. The cap, inserted through flared bore 13, engages plunger 12 and causes shaft 16 to enter bushing 3 against the bias of spring 17. The actual engagement between bodies 8, 9 causes lifting of body 8 so that cam sectors 45 act upon rollers 27, 34 and levers 21, 23, thus causing rollers 28, 35 to approach the sides of the cap. Rollers 28 perform a beading of the bottom of the cap, and rollers 35 perform a screw-threading operation with annular projections 40 following the screw-threads of the container mouth. Individual adjustment of the cam sectors may be made by adjusting springs 50 via brushes 51. Further adjustment of the pressure imparted by the rollers on the cap may be made by varying the length, shape or initial position of cam sectors 45. Also, the caps may not necessarily be entirely metallic but merely incorporate metal portions, for example in plastics material.
