Title: Improved means for feeding blanks for metal working machines
IPC: B23Q7/10
Filed: 1919-05-28
Abstract: 150,399. National Acme Co., and Rindfleisch, B. F. May 28, 1919. Feeding blanks.-Metal blanks, such as drills, studs, &c., are fed to metal-working machines from a hopper so constructed that the weight of the blanks in the hopper is taken off the blank which is being delivered at the bottom thereof. The hopper 2 has its bottom formed by pairs of side rails 10, 11, and the rails 11 are formed with recesses 12 into which two or more of the lowermost blanks enter by rolling and are then relieved from the pressure of the blanks above them by the overhanging wings 13. The opening in the bottom of the hopper is closed by a slide 18; when this is moved to the left one of the blanks under the wings 13 drops into the opening 19 and upon the movement of the slide to the right the blank drops into the receiving-device 50 which may be the work spindle of the stud threading machine described in Specification 166,585, [Class 83 (iv), Metals, Working], of which 17 is the bed. The hopper is secured to an upstanding part of the bed by means providing for vertical adjustment comprising dowel pins and a set of holes at different levels, and a bolt. The sides of the hopper are tied together by bolts 8 and distance sleeves 7. The sleeves, the rails 13, and the slide 18 may be changed for others to suit the size of the blanks under treatment. The slide is worked by a cam and lever 24, and to prevent breakage, in the event of choking of the feed, a yieldable connexion is applied in the form of a cone-ended pin mounted in the end of the lever and pressed by a spring against the surface of the arm 22. In the arm are three depressions or holes united by a groove on slot 33. Normally, the pin engages the central depression; under undue strain it moves back againat the spring and the lever moves forward, the pin sliding along the groove until it drops into one of the end depressions.

Title: Method of and apparatus for the manufacture of electrical connectors
IPC: H01R12/00
Filed: 1972-03-28
Abstract: 1385125 Making electrical connectors INTERNATIONAL COMPUTERS Ltd 2 March 1973 [28 March 1972] 14403/72 Heading B3A A method of making an electrical connector includes positioning a plurality of conductive elements with respect to a sheet or strip 9 of an elastomeric material, forming an assembly by forcing the elements into the material so that they extend substantially therethrough, and treating the opposite faces of the assembly so that the ends of the elements are substantially level with the adjacent faces of the material. A phosphor-bronze strip 2 is etched in an etching unit 3 to form a comb-like structure 4 having spaced teeth. The structure is passed through a test unit 5, which compares the comb optically with a master pattern, and derives signals which control the unit 3. The comb is fed into an insertion unit 7, to which is also fed the strip 9 which may be of silicone rubber or neoprene. The comb structure 4 is cut into sections in the unit 7, and each section is forced into the strip 9 to form groups of toothed sections. The strip passes through an etching unit 10 which etches away the bar joining the teeth of each comb section so that they become individual microspring elements. Grinding rolls 11 treat the upper and lower surfaces of the strip assembly and the ends of the spring elements may subsequently be electro-plated to form domes of a noble metal, e.g. gold or platinum. The unit 7 may be designed to handle individual strips or sheets of elastomer and the micro spring elements may be formed by cutting and shaping a continuous wire of, e.g. beryllium copper.
