Title: Strapping machines
IPC: B65B13/28
Filed: 1941-08-06
Abstract: 551,163. Strapping machines. KAMPER, A. M., PARKES, S., and GERRARD INDUSTRIES, Ltd. Aug. 6, 1941, No. 10004. [Class 45] In strapping machines of the kind in which a wire is tensioned round a package and a helical twisted tie formed, the twisting is effected by a lever 5 which operates knot-ejecting means on its return stroke. The twisting is effected by the usual slotted pinion which is rotated through a larger pinion 9 loose on a lever shaft 7 which carries a spring-pressed radial pawl 12 engaging ratchet teeth formed inside the wheel bore. One-way rotation is thus applied to the slotted pinion on oscillation of the handle 6. The outer end of the binding wire is inserted under an eccentrically mounted toothed grip 15. The wire is then led through the slotted pinion, around the package, and then once again through the pinion, under a cutter blade, and over two anvils 21, 24. The anvil 21 is stationary, and the wire is automatically gripped thereon by a spring-pressed pivoted jaw 22 having an extension 23. The anvil 24 is carried by a spring-retracted hand lever 28 and has a similar'jaw 25, so that repeated rocking of the lever 28 will result in gradual stretching of the wire about the package. On each side of the wheel 9 is a disc 50 loose on the shaft 7 but operated there-from on the return stroke of the lever 5 by spring-pressed radial pawls. The discs 50 are registered by spring-pressed plungers 51 entering a series of depressions 52 in the rim, and have bolted to them toothed plates 49, the teeth 48 of which engage notches in two spring-retracted ejector plungers which throw out the twisted fastening from the slotted pinion on the return stroke of the lever 5. The return stroke also actuates a cutter blade through projections 45 on a disc 46 keyed to an extension 49a of one of the plates 49. The wire is retained by a latch 32 actuated by a nose on the lever 5, and held by a catch 36 released by a cam 38 on the shaft 7. The machine body is cast in two parts having mating housings 3, 4 to enclose the twisting and driving pinions when fitted together.

Abstract: 679,469. Windscreen-cleaners. O'SHEI, W. E. May 12, 1949 [April 12, 1948; April 22, 1948; June 12, 1948], Nos. 10089/48, 11164/48 and 15896/48. Class 138 (i). Relates to a windscreen wiper system having two or more wiper arm spindles actuated by differential fluid pressure, wherein the automatic valve controlling the supply of fluid pressure to the actuating cylinder or cylinders or the like, and the actuating mechanism therefor, is incorporated in a unit separate from the cylinder or cylinders or the like and is coupled to one of said spindles so as to be directly actuated thereby. Wiper arm spindles 4, 5, Fig. 3, are mounted in bearings carried in brackets 2, 3 connected to a rigid metal strip 1. Pinions 9, 10, on the spindles 4, 5, are oscillated by toothed segments 11, 12, Fig. 1, pivotally mounted in the brackets 2, 3, which segments are connected by a metal link 13 for movement together. The segments are oscillated by links 14, 15, connected to the diaphragms of single acting fluid pressure motors 18, 19. The supply of fluid pressure to the motors 18, 19, is controlled by a semi-rotary valve of known type mounted in a housing 21 secured to the bracket 2, which valve is arranged coaxially with and actuated directly by the wiper spindle 4. The automatic valve moves over three ports, one of which is connected by a flexible conduit 25 to the motor 19 while the other two are connected by flexible conduits 26, 27 to a manual valve 28 of known type which is connected by a flexible conduit to the motor 18. When the valve 28 is in the " on " position fluid pressure is applied alternately to the motors 18, 19 by automatic valve operation by the spindle 4. When the valve 28 is in the " off " position the source of fluid pressure is disconnected from the automatic valve and applied to the motor 18 direct, so that the wiper arms are moved to a parking position. The motor units may comprise conventional pistons movable in cylinders. In another embodiment the toothed wheels on the wiper spindles engage with a toothed rack mounted on a framework for longitudinal reciprocating movement, the outer ends of the rack being connected to conventional pistons movable in cylinders. The two cylinders may be mounted in line with the rack and be carried at opposite ends of the framework. Specifications 517,441, 546,483, 557,232 and 557,377, [all in Group XXVI], are referred to.
