Title: Improvements in machines for applying housings to electrical connectors
Inventor: BUSLER WILLARD LEROY
IPC: H01R13/46
Filed: 1965-02-11
Abstract: 1,092,110. Housing flag connectors. AMP Inc. Feb. 11, 1965 [Feb. 27, 1964], No. 5933/65. Heading H2E. A machine is provided in which flag-type connectors are crimped one by one to leads and then enclosed in housings. Each housing is moulded from nylon or polypropylene in the form of two sections 1, 2 linked by hinge pieces 3 so that when the connector has been placed in section 1 with the end of the socket positioned over a raised part 16 and with the conductor resting in a groove 11, the section 2 may be folded over it, apertures 26 snap-fitting over projections 14. The raised part 16 serves to guide a mating tab connector between the resilient bent-round sides of the flag connector. A number of housings are moulded integrally with a carrier strip, Fig. 7 (not shown), having a hole at one end and a boss at the other by which it may be snap-fastened to other strips to form a long strip which may be wound on a spool of the machine for connecting and assembling the connectors. Another spool carries a strip of the flag connectors themselves. On operation of a foot switch, a single-cycle mechanism operates to cause the end of an inserted conductor to be crimped in known manner into the next flag connector by dies (CD, SD), Fig. 12 (not shown), and the flag connector to be severed from its strip. This mechanism then initiates a further single-cycle mechanism which actuates: (a) a feed mechanism, Figs. 16 or 23 (not shown), to move the flag connector into the housing-fitting position, (b) a mechanism, Figs. 13, 14 and 19 (not shown), including an external ring gear (118), through an aperture in the bearing of which the next housing is positioned and which carries a block (121) to fold the section 2 of the housing over the section 1 and the flag connector, (c) a mechanism, Fig. 18 (not shown), including a knife (107) for shearing the housing from its carrier strip and a pin (109) for locating the carrier strip and separating one length of it from another, and (d) a mechanism, Fig. 22 (not shown), for feeding the carrier strip (41) one step forward through the bearing of the gear (118).

Patent GB-466231-A (GB)
Title: Improvements in or relating to machines for sewing articles to work
IPC: D05B3/14
Filed: 1936-03-02
Abstract: 466,231. Sewing-machines. AMERICAN BUTTON SEWING MACHINE CO. March 2, 1936, No. 6322. Convention date, Nov. 18, 1935. [Class 112] In a machine for sewing articles, such as four-hole buttons, to work, the means for relatively moving the needle and work, and the thread-severing mechanism, are so operated that the article is secured to the work by a plurality of disconnected sets of stitches during a single complete, uninterrupted machine cycle. This eliminates the cross-thread on four-hole buttons attached by stitching, without stopping the machine to cut the thread between the formation of the groups of stitches. The invention is shown as applied to a machine for attaching four-hole buttons. The needle 5 is reciprocated by a shaft 6 and crank 7, the shaft 6 being driven from the power shaft 10 which drives the looper 15. The button clamp 16 is of conventional type and carried by the usual arm 17 on a cloth plate 20. The plate 20 and arm 17 are vibrated in two directions to bring the pairs of holes in line with the needle in the usual manner. The thread passes through tensions 35, 36, 37, the second two of which act as thread grippers. The groove 40 of the cam 30 causes the work to be vibrated so that a predetermined number of stitches are placed in a pair of Holes of the button, and causes the needle to pass several times through the same hole to knot the last stitch. At this point the cam 85, carried by the cam 30, reaches the position shown in Fig. 8, where the rod 73 co-operating with the tension 37, drops into the notch 86. The thread is then clamped in the tension 37. The dropping of the rod 73 operates a bell-crank 66 so that the thread is simultaneously released in the tension 36. The tension 37 is adjusted so that the clamped thread is broken after the formation of the first group of stitches, a, Fig. 10. To provide sufficient starting length of thread for the next group of stitches b, Fig. 10, a finger 50 secured to the rock-arm 100 pivoted on the button clamp-opening shaft 101, is actuated to pull off thread from the released tension 36. As the rod 73 rides up the inclined face 90 of the notch 86, Fig. 8, the finger 50 is returned to its original position, the tension 36 closed and the tension 37 released. The second group of stitches b is then formed in the button after the manner of the group a, the machine coming to rest automatically after the thread has again been broken and with the tension 36 open and the tension 37 closed.

[Classes 83 (ii) and 83 (iv)] Soldering.-In bonding aluminium or aluminium alloys to steel, the surfaces of the metals are each first coated either with tin or with a cadmium zinc alloy, whereupon in the first case the coated steel is provided with a second coating of tin containing aluminium and in the second case it is provided with a second coating of cadmium-zinc alloy containing aluminium. The aluminium may be coated with tin by brushing or scraping the surface while immersed in molten tin. The steel may be first coated with pure tin and then with tin containing about 0.5 per cent. of aluminium. It is stated that repeated immersions of steel in a bath of pure tin do not appreciably increase the thickness of the coating, and also that tin containing aluminium does not wet the surface of uncoated steel. For the second coating subsequent use may be made of the bath in which the aluminium has been first coated. The two tinned surfaces are united by heat and/or pressure. In the modified process the aluminium may be coated with a cadmium zinc alloy containing 82 per cent of cadmium and 18 per cent of zinc and the steel provided with a first coating of the same alloy and then with a second coating of a similar alloy but containing also aluminium. Use is preferably made of the bath in which the aluminium has been coated.

Title: Improvements in and relating to the manufacture of electric resistances
IPC: H01H33/16
Filed: 1941-05-19
Abstract: 547,449. Wire resistances. HENLEY, J. A., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. May 19, 1941, No. 6428. [Class 37] A resistance element in or for use in conjunction with switch gear of the air or gas blast type is enclosed in a rubber composition or equivalent insulating material which is initially mouldable but is rendered hard after enclosure of the element to provide a rigid weather-resistant sheath. The insulating material may be a mixture of natural rubber and sulphur, with or without the addition of a filler such as clay, which is subjected to a curing process for substantially vulcanizing the mixture. A tube 1 of such insulating material is encircled at one end by a steel or other metal ring 2 and at an intermediate point by a similar ring 4. The resistance element 5 consists of a cotton, silk, or other fibre-covered wire, which is bared and anchored to the ring 2 by one of several screws 6. The tube 1 is placed on a mandrel and rotated and the resistance wire is closely wound in a single layer between the rings 2, 4. A portion of the wire is then bared and anchored to the ring 4 by one of several screws 7. A solution of rubber or other insulating varnish is then applied and allowed to dry, and a second layer is wound from the ring 4 back to the ring 2, where the wire is bared and anchored to the ring 2 by another screw 6. Rubber solution is then applied and a similar layer is wound from the ring 2 to the ring 4 and so on. The resistance wire may be soldered to the rings 2, 4 at the points where it is joined thereto. The tube 1 with the wound resistance element is then inserted into a sheath 8 of mouldable insulating material having flanges 9, 10 and circumferential stiffening ribs 11. The whole assembly is then subjected to a curing process until it becomes hard and rigid. The resistance may be used in the gas blast switches described in Specifications 534,224 and 541,949, [Group XXXVII].

Title: Improvements in or relating to photographic cameras
IPC: G03B17/04
Filed: 1943-04-23
Abstract: 563,415. Photographic cameras. KODAK, Ltd. April 23, 1943, No. 6573. Convention date, May 11, 1942. [Classes 97 (i) and 98 (i)] A photographic camera comprises a fixed tubular member extending through the front and adapted to receive interchangeable lens mounts, together with a rotatable but not axially movable focusing member, adjacent the front, which is capable of operative connection to the inserted lens mount and is also operatively connected to the ray-deviating means of a range-finder, these means being carried by the camera front whilst the other optical parts of the range-finder are carried by the body. The camera shown comprises fixed tubular members 3, 4 which may telescope into the body as disclosed in Specification 511,731. The tube 3 carries a hollow front 2 containing the adjustable elements of the range-finder and is adapted to receive an interchangeable lens mount 36. It also carries, mounted on ball bearings 62, a rotatable focusing member comprising a knurled ring 33 to which are secured a driving ring 45 and a cam ring 18 which operates the rangefinder. The driving ring contains spring- pressed pins 34 which engage in grooves 35 in the lens mount. When the mount is inserted, spring-pressed balls 39 in it slide in aligned grooves 48, 39<1> in the ring 45 and a tubular liner 40 of the member 3 until when the mount is fully home they come opposite the ends of that one of a number of sets 41, 42, 43 of cam grooves which is appropriate to the focal length of the lens, so that rotation of the mount by the ring 33 now causes axial focusing movement of the lens. The initial rotary movement of the ring 33 causes a spring-pressed pin 50, carried by it, to snap over a fixed stop (not shown), so preventing the grooves 48 being accidentally brought into alignment with the grooves 391 and possible falling out of the lens. The range-finder comprises levers 8, 9, the lower ends of which are held by a spring 19 in contact with cam surfaces on the ring 18 so that rotation of the ring varies the distance between positive lenses 12, 13 mounted in their upper ends. The other optical elements are mounted in the camera body and comprise lenses 22, 23 and mirrors forming a split image which is viewed through an eyepiece 26. The viewfinder comprises an eye-lens 32 and negative lens 20 carried in a frame which is pivoted at 21 and engages the spring 19 by a fork 29, the spring being so designed that its changes of form produced by the movements of the levers 8, 9 cause vertical movements of the lens 20 which correct for parallax error.
