Abstract: 1,133,183. Folding and finishing edges of non-metallic sheet material. L. G. FREEMAN. 25 May, 1967, No. 24439/67. Heading B5K. Apparatus for folding the marginal portions 3 of a cut-out 2 in the vamp 1 of a lady's shoe comprises an upper die assembly including a member 11 on a mounting plate 17 secured to the plunger of a conventional bench type cut-out machine having a fixed base and an overlying reciprocating plunger which, upon actuation, moves the member 11 downwardly into contact with a lower die assembly including a member 4 and a subplate 9 spaced upwardly from a baseplate 23. A masking plate 26 is hinged at 27 to the subplate 9 and a gauge plate 30 is slidably mounted in guides 29, 29a on the plate 26. The member 4 projects upwardly through an opening 28 in the subplate 9 and is mounted on a vertically movable plate 19 urged upwardly by springs 20. A gauging head 5 of a size to fit within the initial cut-out opening 2 in the workpiece 1 is provided on the member 4. A shoulder 6 corresponding in size to the final size of the cut-out opening surrounds the head 5. The member 11 has a recess 13 to receive the head 5 when the dies are brought together, the recess 13 being surrounded by a ledge which seats on the shoulder 6. A vertical wall 14 terminates in a flared shoulder 15 which is adapted to coact with the subplate 9 to fold the portions 3 back on to the workpiece 1. In operation, the workpiece 1 is seated on the head 5 and the plate 26 is lowered with the plate 30 in its forward or operative position, Fig. 9 (not shown). The plate 30 has an opening 32 therein of the size to surround the member 4 so that, as it is brought downwardly, it forces the workpiece 1 downwardly around the member 4 and causes the portions 3 to be bent upwardly. When the workpiece 1 has been seated on the subplate 9, the plate 30 is retracted and the workpiece is held against the subplate 9 by the plate 26. The upper die assembly is lowered and the member 11 moves the member 4 through an opening 10 in the subplate 9. As the members 4, 11 move downwardly the upwardly projecting portions 3 come into contact with the shoulder 15 which folds them outwardly and juxtaposes them against the workpiece 1. Adhesive and/or a stiffener has been previously applied to the workpiece in the area surrounding the portions 3 and under the pressure of the upper die the portions 3 will be pressed into tight contact with the adhesive and/or stiffener. The workpiece 1 is removed after upward movement of the member 11.

Title: Jet forming apparatus
IPC: B24C7/00
Filed: 1973-05-25
Abstract: 1424896 Blasting B E HART 5 June 1974 [25 May 1973] 25254/73 Addition to 1403528 Heading B3D A method of operating a particulate material jet forming apparatus comprises producing a jet of particulate material and liquid at an outlet nozzle of a gun 1, the material and liquid being drawn into the gun from a supply means 14 by vacuum created in the path of the mixture by a high pressure jet of liquid 8 around the path thereof, and diverting at least some of the liquid forming the jet into the path of the mixture flowing to the gun adjacent the outlet of the supply means 14 therefor. The gun 1 is as described in Specification No. 1,403,528 with the valve assembly 2 rotated through 90 degrees relative to sand and water mixture flow passage 3. Depression of handle 5 operates valve 2 so that water at a pressure between 2000 and 5000 p.s.i. passes through passages 11, 7 and impinges on a tapered surface 8 to form a conical jet which, in turn, creates a vacuum drawing a mixture of sand and water in hopper 14 through passages 19, 20, flexible hose 12 and passage 3 to the nozzle, an extension 9 of a tubular member 10 forming passage 3 protecting the surface 8 from abrasion by the sand and water mixture. To prevent a deposit of sand in passage 3 when the valve assembly is closed, the return port 4 of valve assembly 2 is coupled by a flexible hose 16 to a passage 22 in the outlet 13 of the hopper, and a bleed port in passage 11 is connected by a flexible hose (17, Fig. 2, not shown) to a passage 24 in the outlet 13 having a nozzle 25. When the apparatus is in use, the water which passes through the bleed port and is formed into a jet by the nozzle 25 assists the vacuum created by the conical jet in drawing the mixture of sand and water from the hopper 14. When the apparatus is not in use, the water from the supply passes along hose 16, passages 22, 20 and passage 3 to clear the gun of sand. The back pressure of the water in hoses 16, 12 prevents the mixture of sand and water leaving the hopper and may cause turbulence, and hence mixing, of the mixture in the hopper. In an alternative arrangement, the supply to nozzle 25, instead of coming from the bleed port, is from the pump outlet.
