Abstract: 683,693. Wire strainers. POWER & SONS (BOX STRAPPING), Ltd., F. A., and PADMORE, J. R. Sept. 19, 1950 [June 20, 1949], No. 16274/49. Class 45 [Also in Group XXXII] A slack-gathering device for a wiretying machine for packages is resiliently loaded to take up any loss of tension in the wire while it is being trained round the package to prevent slack forming in the trained loop. A plate t is attached to the rotatable training ring of a machine of the type described in Specifications 523,786 and 523,829, and supports two pulleys n, o, which are mounted in slots r, s on blocks p, q which slide on rods x. The pulleys are forced away from each other by springs y surrounding the rods x. Wire from a supply reel is fed to a feeding device (not shown) which is carried by a plate v and from the final roller of the feeding device passes round the pulleys n and o in succession and then to a pulley (not shown) which is mounted in a central aperture u in the plate t. From this pulley it is fed to the training pulley on the wire-training ring. The wire is subjected to an adjustable tension in the feeding device which causes compression of the springs y. During training the springs move in their slots to take up any variation in this tension caused by the difference between the shapes of the package and training ring.

Abstract: 352,185. Bottle-washing machines. ADAM, H., 67, Keplerstrasse, Heidelberg, Germany. May 27, 1930, No. 16302. Convention date, May 27, 1929. [Class 138 (i).] In bottle-washing machines of the type in which rinsing jets enter and are withdrawn from the bottles and in which the bottles are held in an inverted position in holders mounted on an intermittently rotating supporting plate, the supporting plate which rotates about a vertical axis is conical with the holders in tiers so that the bottles are easily accessible and the rinsing water and labels readily disposed of. As shown, the bottle holders e are supported on a conical plate d which is raised and lowered over squirt tubes q by means of a shaft 1, crank b, and forked connecting rod b<1>. Intermittent rotation of the plate to bring the bottles to successive jets is obtained from the shaft 1 through toothed gearing 15, 16, and a crank pin h, which enters between vanes on the plate d. When the plate is lowered a roller i enters between the vanes and retains the plate in position. Instead of the plate d being raised and lowered the same action may be performed by a frame carrying the squirt tubes. Strainers q which are detachable serve for collecting the labels. Water from the interior of the bottles is discharged through the plate d while water from outside jets n is led with the labels along channels o. In a modification the intermittent motion of the supporting plate is obtained by a pair of cams.

The tup 17, Fig. 1, is guided at its corners by ways 16, Fig. 3, on standards 12, 13, each of which is double with space for an intermediately situated chain 21. A motor 35 on the head 15, supported by and connecting the standards, drives by V-belts a flywheel 33 running by roller bearings on the shaft 28 carrying a pinion driving, through gearing, chain - wheels 22. The fly - wheel drives the shaft through a plate clutch 37 controlled by an annular air-cylinder 39. A similarly constructed brake 41 is controlled by a cylinder 47 and the arrangement is such that when the clutch is engaged the brake is off and conversely. The chains are of triple roller form, the centre rollers running on ways 61 on a separator 55 located between the up and down runs. The outer rollers engage lugs 60 on the tup during lifting, and this engagement is effected by lateral movement of the separators by pistons 58 controlled either manually or by dogs actuated by the tup. Reverse movement of the separators frees the tup for the drop. Instead of moving laterally, the chains may be mounted to swing about the axes of the chain-wheels 22. In modifications, the tup has rollers or lugs to engage lugs on the lifting chain.
