Title: Improvements in and relating to coil winding machines
IPC: H01F41/06
Filed: 1930-02-11
Abstract: 348,645. Traverse mechanism for coilwinding machines. OWEN, C. J. and AUTOMATIC COIL WINDER & ELECTRICAL EQUIPMENT CO., Ltd., Winder House, Douglas Street, London. Feb. 11, 1930, No. 4602. [Class 120 (ii).] The traverse of a hand or power driven coilwinding machine of the type having two leadscrews, has half-nuts carried by a rocking arm with a doubly bevelled pin, the ridge bounding the bevelled surfaces of which being at an angle to the line of travel of the traverse carriage and the pin being engaged by a projection on an arm, slidable in the traverse carriage and having a pin engaging pre-set stops to cause the projection to ride over the ridge and the arm carrying the half-nuts to reverse the carriage movement. The carriage slides along guide-rods f, g, Figs. 2 and 3, the rod f being surrounded by tubes h<1> extending from each side of the carriage. Lugs h<8> on the carriage support the arm k carrying the half-nuts k<2> which are held in engagement with the lead-screws b, c by the downward pressure on the bevelled surfaces k<4>, exerted by a conical projection h<13> on a lever h<10> pivoted at h<9> and having a tension spring hll. The pivot pin h<9> encounters a stop just prior to each reversal of traverse, which displaces the lever h<10> relatively to the carriage and causes the projection h<13> to ride up one side the surface k<4> till it crosses the bounding line between the two bevels, which is at an angle of 45‹ with the direction of movement of the carriage, thus rocking the lever k. The wire guide comprises an arm j, pivoted on the traverse carriage, having thin steel plates j<1>, Fig. 2, above which are two rollers or rods j<2> between which the wire passes, an adjusting screw h<7> abutting against a lug j<3> limiting forward movement of the arm, but allowing it to be swung back for bobbin changing. A paper feeding device such as is described in Specification 348,678 may be mounted behind the leadscrews, which have an adjustable friction drive d. d<1> such as described in Specification 199,417, [Class 120 (ii), Spinning, twisting, &c.], and are geared together.

Abstract: 702,068. Welding by pressure. OHIO CRANKSHAFT CO. Feb. 28, 1951 [Feb. 28, 1950], No. 4904/51. Class 83 (4) The opposed surfaces of two members to be pressure butt welded are heated by applying high frequency electromagnetic induction heating to the members in the region of at least a part of the outer perimeters of their opposed surfaces and passing an electric current through the members in a direction transverse to the opposed surfaces to produce secondary heating in the regions not heated by the high frequency heating. In an embodiment, a coil 14, Fig. 1 (not shown) connected to a source of high frequency current is arranged about the end surfaces 12 of rods 10, 11 while a direct or low frequency alternating current from a source 22 is applied longitudinally of the rods 10, 11. The surface 12 may be coated with lead, copper, nickel or chromium or placed in contact with thin sheets of such metals, and the rods 10, 11 may be vibrated, reciprocated or twisted relatively during welding. In another embodiment a coil 14, Fig. 3, connected to a high frequency source 16 is arranged about the ends of two tubes 30, 31, spaced apart slightly with a plug 63 of carbon, graphite, steel, &c., forced into the end of each tube. A clamp 37 preferably of copper is secured to each tube 30, 31 with rods 50, 51 attached to the clamps 37 and to hydraulic cylinders 52. Current from a direct or low frequency source 64 is supplied through the clamps 37 so that secondary heating takes place at the surfaces 65, 66. Welding is effected by drawing the clamps 37 together by applying hydraulic fluid to the cylinders 52. The plug 63 may be left in position or removed after welding. Electric vibrating means 70 are provided to vibrate the tubes 30, 31 during welding. In a further embodiment, two tubes to be welded have outwardly tapering recesses in their adjacent ends so that a tapered carbon block carrying a split metal ring may engage therein and hold the tubes slightly apart. Heating is effected by a high trequency coil and longitudinally applied direct or low frequency current after which the tubes are brought together, thus breaking the carbon block. U.S.A. Specification 2,583,362 is referred to.

IPC: A43D8/00
Filed: 1920-02-20
Abstract: 163,485. British United Shoe Machinery Co., Ltd., (United Shoe Machinery Corporation). Feb. 20, 1920. Boot-sole stitching and assembling machines.- The parts of a turn-shoe or welted shoe are assembled without lasting and stitched together with the usual kind of seam in a speciallyarranged sewing-machine. The upper is moulded and the insole inserted and secured by a tack 13, as shown in Fig. 3, before being introduced to the sewing- machine. After the stitching is completed, a last somewhat larger than the shoe is forced into it and the shoe is thereby stretched into shape. Subsequent operations may then be performed with the last in the shoe. In the sewing-machine, the insole is supported by a channel guide 36 and a U-shaped guide 40 which passes between the sole and upper and embraces the feather of the sole. The edge of the upper is guided by an edgeguide 76 and is held between the upper surface of the guide 40 and a presser-foot 64. The upper part of the presser-foot is formed as a welt-guide. All these parts pivot about the axis 54 and, with the exception of the upper edge-guide 76, move with the feed-slide.' The presser is secured by a screw 168 upon a lever boss having toothed engagement 98 with a lever 102. By means of the lever 102, a cam lever 112 and an intervening spring 114, the presser is periodically pressed heavily upon the work and is locked by means of two detent levers 120. The presser is released when a cam depresses the tails 130 of the detent levers or when a treadle-operated lever 138 is depressed and a lever 134 having a pin 136 projecting into the plane of the detents is turned thereby. The guide 40 is normally pressed lightly upon the work by a spring 58; it transmits the heavy pressure of the presser to the insole and is lifted free of the sole, when the presser is positively lifted by the cam-lever 112 and the rod 106, by means of a screw 72 which contacts with a projection 74 on the boss 48 of the guide 40. In ether respects, the machine is substantially the same as the Goodyear outsole lock-stitch machine.
