Title: Improvements in or relating to the manufacture of sliding clasp fasteners
IPC: A44B19/48
Filed: 1935-06-07
Abstract: 458,082. Sliding clasp fastenings. LIGHTNING FASTENERS, Ltd., Imperial Chemical House, Millbank, London.-(Chappuis J. A. ; 2, Rue Pury, Neuchatel, Switzerland) June 7, 1935, Nos. 16670/35 and 14909/36. Addition to 418,905. [Class 44] Sliding-clasp fastener elements after having been orientated by falling down an inclined plane fitted with angular baffles, as described in the parent Specification, pass into a steeply inclined slotted guideway in which the elements slide downwardly with their legs lying horizontally and in the plane of the guideway, and thereafter the elements are transferred to a rail along which they are finally moved horizontally to the clamping device of the apparatus in pack formation with the legs horizontal. Elements from the hopper 1 pass beneath a helically grooved roller 5 to the inclined plane 9 and must therefore be lying flat with their interlocking projection uppermost. These elements are orientated by engaging the angular baffles 11 ... 17 and then enter the slotted guideways, the engagement of the rectangular interlocking projections in the vertical slots 40, 41 causing the elements to lie with the legs horizontal. When an element reaches the bottom of the slotted guideway it is transferred to a conveying rail 55 by a reciprocating plunger 59, shown on an enlarged scale in Fig. 4. The rail 55 may be wholly horizontal but in the apparatus shown the rail is at first steeply inclined and therefore the plunger 59 is provided with a longer upper pin 57 so that the element is turned over through nearly 90‹ to straddle the nearly vertical rail 55. The pins 57, 58 are spring mounted to yield if an element jams. A light friction lever 66 retards the elements so that a pack formation is obtained. Friction rollers 70, 71 feed the pack formation along the final horizontal portion of the rail 55 to the clamping device 64. The elements move along the rail 55 with their legs disposed horizontally in a vertical plane ; a guard rail 65 engages the heads of the elements. The angular baffles 14.. 17 are connected by a spider 31 and vibrated by a cam-actuated rocking lever 22. Incorrectly disposed elements are either skimmed off or turned to proper position by vibrating needles 44 situated just in front of the entrance to the slotted guideways 40, 41. Adjustable pieces 36, 37 at the entrance to the guideways allow the slot width to be adjusted.
Patent GB-1381796-A (GB)
Title: Packaging machine
IPC: B65B43/12
Filed: 1972-04-11
Abstract: 1381796 Packaging apparatus R J WEIKERT 11 April 1972 [12 April 1971] 16722/72 Heading B8C In apparatus for packaging liquid or semiliquid products such as milk or ice-cream mix, plastics bags formed in a continuous web are opened, filled with measured volumes of the product, and sealed in a non-stop, continuous passage through the apparatus. The bags are drawn from a supply roll 30 on stand 16 or 18 and pass through the apparatus between moving belts 174 and supported on moving belt 104, the spacing and height of these belts being adjustable for different bag sizes. Lateral seams 36 stop short of the free upper edges 38 of the bags so that, in being drawn over a plough 42, the bags are opened and pass beneath a filling station 12. Canted rollers 58 tension the web of bags, and grooved rollers 60 press the edges 38 on to teeth 70 on two endless conveyer chains 64. As the opened bags pass beneath station 12, measured volumes of the product are conveyed from a hopper 287 in transfer cans 252 moving in an endless path defined by members 206, 208. Cam track 212 raises the cans as they pass under hopper 278 to contact and open spring-loaded valves 280, thereby releasing the product into the cans. Cam track 212 then lowers the filled cans so that nozzles 254 enter the bags, the product being released into the bags as ears 268 of rotary valves 256 are tripped by fingers which subsequently trip ears 270 to close the valves. The cam track then raises the nozzles out of the bags for ultra-violet sterilization over a drip pan 506. The relative speeds of the opened bags and the moving nozzles are constantly variable by a control unit receiving signals from a photo-electric device scanning indicia on each bag entering the machine. Filled bags finally pass between moving heated sealing bands in sealing unit 14, and excess bag material is trimmed off. With larger bags, bigger transfer cans 252 are used with a second hopper, and are filled in two steps from both hoppers. Again, a bag may be filled by the insertion simultaneously of multiple nozzles 254.

[Class 122 (i)] The shaft 1 of an eccentric having parallel flats 2 at its middle section or block 3 and adjusted in the sheave 5 by a pair of screws 6a, 6b passing through the block and bearing against the sheave walls, as described in the parent Specification, has the two screws engaging within the sheave either by gear-wheels 12a, 12b directly engaging and mounted on pins 9a, 9b fixed in the screws or by indirect engagement of gear wheels through an intermediate piston. The pins 9a, 9b are locked by nuts 15a and one of them carries a head rotatable to effect the adjustment of the screws and eccentric by a tool inserted through a hole 13a in the eccentric strap. In a modification the sheave has lateral extensions enveloping the strap, and an adjusting pinion is located in a recess in the face of one of these extensions and is therefore accessible in any position of the eccentric.

In a device 10, e.g. for workpiece transfer on a production line, a reciprocating drive rod 16 acts through a cam 21 and pivoted follower 22 to move a shaft 15 axially, and simultaneously through a rack 19 and pinion 20 and a pin and slot lever system 31, 32, 35, 34 to rotate the shaft 15, which carries a workpiece arm 12. The hollow lower portion of the shaft 15, Fig. 7, contains a spring 48 which acts on a cross-pin 49 projecting through slots 47 of the shaft to engage a thrust bearing 50, to urge the base nut 29 of the shaft against a roller 28 of follower 22. Axial travel of the shaft 15 is limited by an adjustment nut 42 and lock nut 44 on a threaded portion 40 of the shaft. A pin 36 on the lever 34 engages bushes 38 in lugs 39 of the casing 11 to locate the shaft 15 at the extremities of its rotary movement. A guide roller 65, Fig. 7, holds the rack 19 in engagement with pinion 20. The reciprocating drive rod 16 may be replaced by a rotary drive to an extension of the pinion shaft 30, and the levers 31, 34, or the rack and pinion 19, 20 may be replaced by alternative linkages.

Abstract: 936,360. Internal shoe drum brakes. ROBEY & CO. Ltd., and A. CROMPTON. May 1, 1962 [May 16, 1961], No. 17736/61. Addition to 846,555. Class 103 (1). The arrangement disclosed in the parent Specification is modified in that it is applied to an internal shoe drum brake, the spring assemblies acting between each sliding shoe-carrying element and a fixed frame supported within the drum, and the fluid pressure-operated means opposing the spring pressure also being arranged within the drum. As shown, the brake comprises two units 1 each comprising a sliding element 5 carrying a brake shoe 4. Each element 5 slides in arcuate guides 6 and is urged radially outwardly by springs 7 bearing against a cover-plate 8 which is adjustably positioned by bolts 9 threaded into the frame sections 3. To facilitate adjustment a fluid pressure cylinder 12 is mounted on the frame so that extension of its piston 13 moves the cover-plate to compress the springs. By supplying fluid at the same pressure to the cylinders 12 of the two units the springs can be set to the same compression, in which state they are held by manual adjustment of the bolts 9. The fluid-pressureoperated means opposing the spring pressure is a further cylinder 10 secured to the frame, the piston 11 of which bears against a central portion of the element 5 so as to move the latter radially inwardly when pressure fluid is admitted to the cylinder.
