Abstract: 727,963. Hydraulic machines. BENDIX AVIATION CORPORATION. May 26, 1950 [May 31, 1949], No. 13341/50. Class 69 (2). Hydraulic apparatus, particularly for agricultural implements, comprises a valve 16 controlling the flow of pressure fluid to a motor 15 and having a valve piston movable from a neutral position, in which the motor is locked, into positions for moving the motor in opposite directions, the valve piston being actuated by a control handle 101 movable selectively through any one of a number of parallel paths and being urged by a spring 109, Fig. 4, into one of said paths in which a shoulder element 102 connected to the valve piston is actuated by collars 24, 26, connected to the motor piston rod 22 for restoring the valve piston to its neutral position when the motor piston reaches a predetermined position. The apparatus is similar to that described in Specification 715,111 and has its valve piston connected at one end 386b to the handle 101 movable in a plane parallel with the valve axis and adapted to pivot with the valve piston about the said axis in order to bring the shoulder element 102 into or out of the path of the two collars 24, 26 which are carried by an arm 23 connected to the motor piston. The collars are adjustable for varying the stroke of the piston. Movement of the handle and hence the valve member is normally limited by a stop screw 116 but for slow movement of the piston, the handle together with the valve piston is moved to the right, Fig. 4, against the spring 109. The shoulder 102 is thereby moved from the path of the collars and the longitudinal movement of the valve member is then limited by stops 110, 111, which do not allow the valve to fully unmask the liquid supply port to the motor 15. In another position of the handle its movement is unrestricted.

Abstract: 150,424. Jerram, A. E., Gouldbourn, J., and British United Shoe Machinery Co. June 2, 1919. Pulling-over.-Consists in detail improvements in the type of pulling-over machine described in Specifications 16398/15 and 103,349. in which the bulk of the operating mechanism and a substantially vertical actuating cam-shaft therefor are located below the shoe. The head 4, Fig. 1, carrying the pulling-over and fastening mechanism and cam shaft 5, is pivoted at 8 so that it may be swung as a whole into. a position where the carn shaft is substantially horizontal to facilitate adjustment and renewal of parts of the operating mechanism. In this position the head rests on a strut 16, and the bevel wheel 21 on the cam-shaft is separated from its driving pinion 72, but may be-turned by a bevel pinion operated by a hand-wheel 18. When the head 4 is in its normal position the machine is started by a pedal 64 having a pivoted 62 passing through a slot in a member 48 connected to a clutch actuating rod 46. The link 62 has a wear plate 63 which engages a block 52 on the member 48 depressing this member against the action of a spring plunger 50 out of the path of a lever 56 operated by a cam on the shaft 5, and allows springs 38 to clutch the pinion 72 to a revolving pulley 26. When, in the normal operation of the machine, the lever 56 disengages the clutch, a brake 34 is brought into action to stop the pinion 72. A lever 74 carries a stop 76 which, when desired, is brought into the path of a lug on the member 48 with the effect that depression of the pedal 64 frees the brake 34 without engaging the clutch so that the operating mechanism can be turned by the hand-wheel 18. The tack-puffing plunger 94 is pressed forward by a spring 96 and pulled back by a rod 88 having a hook 90 engaging a pin 92 in the plunger. The rod 88 is pulled back until an adjustable screw 100 engages a projection 98 and frees the hook 90 from the plunger, which is then returned byits spring. The tack pockets 144, Fig. 4, are closed by oppositely movable plates 146, 148 pressed together by a spring 150 and separated by the driver. The tack carriers 106, Fig. 2, are pivoted to driver-bar arms 108 and are looked in tack driving position each by a pawl 110. When the driver-bar arms move out into inoperative position gear segments 118 on the tack carriers are brought into mesh with gear segments 120 connected by links 134 and cranks 136 and operated by a cam lever 130. As the gear segments mesh, the pawls 110 are engaged by screws 140 to release the carriers and allow them to be turned by the gear segments into tack-receiving position. The tacks are allowed to settle in the carriers during the time the machine is stopped for the operator to adjust the upper to the last, being blown into the tack carriers before this stage, and the carriers are moved from receiving to driving position on re-starting of the machine. Specification 7005/00 also is referred to.

Abstract: 1,032,278. Suction moulding pulp articles. DIAMOND NATIONAL CORPORATION. April 8, 1963 [May 31, 1962], No. 13899/63. Heading B5A. In a method of suction moulding pulp articles a series of suction dies 10 (Fig. 1, not shown) is rotated through a vat 12 containing a pulp slurry 14, vacuum being applied to the dies to cause pulp to be deposited thereon, the dies then passing to a pressure applying station wherein whilst the pulp is still in a gelatinous stage pressure is applied to the outer surface of the pulp deposit on the die by a continuously moving surface, e.g. an endless belt 20, to provide a smooth surface on the pulp article formed on the die. The pressure is preferably initiated whilst the die is still submerged in the slurry and continues until all moisture has been squeezed out of the deposited pulp. The continuously moving surface may act to mask a portion of the deposited pulp on the die from further deposition. Thereafter the dies may pass to other pressing stations and drying stations. The pressure applying means 20 may have a patterned surface and may be formed from a laminate of rubber and canvas duck layers, or rigid plates, plastic sheets, or rubber rolls.
