Title: Improvements in cheese cutting method and apparatus
IPC: B26D1/547
Filed: 1954-07-28
Abstract: 757,270. Cheese-cutters. TRIGGS, W. W. (Kraft Food Co.). July 28, 1954, No. 22028/54. Class 87(2) An uneven surface layer is removed from a block of cheese by passing a cutting element through the block while applying pressure to the block in a direction perpendicular to the surface and in an area immediately preceding the forward edge of the cutting element. The block may at the same time be cut in 'planes parallel to the surface layer, e.g. by wire cutters. As shown, the cutting element comprises a blade 19 horizontally mounted between blocks 75 which have bores threaded at 117 to engage threads 115 in screws 113 simultaneously operated to vertically adjust the blade 19 The pressure applying means comprise a roller 85, horizontally mounted just forward of and above blade 19, which, in operation, exerts downward pressure due to springs 91 engaging its end bearing blocks 87 in guides 89. To cut the block through its central horizontal plane a wire 21 is mounted horizontally between blocks 77 threaded at 121 to engage an extended threaded part 119 of screw 113, the thread 119 having half the lead of thread 115 so that blade 19 is always twice the distance of wire cutter 21 above the block supporting surface. In operation the cheese block is placed on a platform 31 and against a backing member 25 mounted thereon and having a vertically adjustable upper part 53 and a fixed lower part 49. The platform 31 is then hydraulically operated to move forward, on rollers engaging rails 13 on stand 71, so that the blade 19 and wire 21, respectively trim the surface and divide the block, the rollers 85 resiliently pressing on the top surface. Rollers 61 on the sides of the part 53 engage cams 131, mounted on the blocks 75, which deflect the part 53 downwards so that its upper edge is close to blade 19 at the finish of the cutting operation, thus preventing a ragged cut.

Title: Improvements in electric resistance welding machines
IPC: B23K11/04
Filed: 1948-08-24
Abstract: 654,601. Electric welding. RESISTANCE WELDERS, Ltd., and GORDON, S. H. Aug. 24, 1948, No. 22321. [Class 83 (iv)] [Also in Group XXIX] In an automatic flash butt welding machine in which the feed increment of the moving head 12 is accompanied by liquid displacement and the rate of movement during flashing is controlled by restricting the flow of the displaced liquid, this restriction being removed at the end of the flashing period to permit the head 12 to move rapidly forward to effect butting, the head 12 is displaced by liquid pressure generated in an intensifier, the rate of movement being controlled by restricting the flow of liquid placed under pressure by the intensifier. The head 12 is connected to a piston 14 in a cylinder comprising an intensifier chamber 15 and a dashpot chamber 16, while an air cylinder 17 contains a piston 18 integral with a plunger 19, the latter being so connected to the piston 14 that on retraction of the plunger 19 the piston 14 is pulled back also. Valves 22, 23 are spring- urged to allow flow only into chambers 16, 15 from a reservoir 26 but are displaceable by stems on plungers 27, 28 in cylinders 29, 30 which may be opened to air pressure. A metering valve 31 allows restricted flow from the chamber 16. A compressed air source is connected to a manually-operated valve 33 and to a solenoid-operated valve 34, the valve 33 in its " return " position connecting the air supply to cylinder 30 and to the front end of cylinder 17 and its " forward " position connecting the rear end of the cylinder 17 to the supply, the ports not connected to the supply in either position being connected to exhaust. The valve 33 is mechanically linked to a switch 35 which is closed when the valve 33 is in the forward position, thus completing a contactor circuit to supply current to the work and the solenoid valve 34 circuit through a trip-switch 36, to put the valve 34 to exhaust. In operation the valve 33 is placed in the forward position when both cylinders 29, 30 are to exhaust, thus allowing valves 22, 23 to close and the air supply is connected to cylinder 17 to move the plunger 19 into the chamber 15 to move piston 14 and the head 12 forward slowly since liquid escape from the chamber 16 is by the restricted metering valve 31. Movement continues until the switch 36 is tripped, breaking the solenoid valve circuit and allowing air into cylinder 29 to open the valve 22. Liquid then freely escapes and the head 12 moves rapidly forward to butting action. The valve 33 is then placed in the return position when with valves 22; 23 open, the piston 18 draws plunger 19 and hence piston 14 and head 12 rearwardly. The Provisional Specification describes a welding-machine in which the moving head is moved by liquid means, the metering valve being associated with these liquid means to limit the rate of supply thereto and therefore to limit the speed of the moving head.
