Title: Method and apparatus for producing an elongated metal member with metal elements welded thereto at spaced positions
IPC: B23K11/00
Filed: 1965-05-06
Abstract: 1,090,747. Making barbed wire; welding by pressure; barbing by cutting. AMRERICAN MACHINE & FOUNDRY CO. May 6, 1965 [May 7, 1964], No. 19105/65. Headings B3A, B3R and B3W. In forming an elongated metal member with a succession of metal elements welded thereto at spaced positions, the elongated member and another elongated metal member are welded together at spaced-apart positions and the other member is severed between the welds. In an embodiment for making barbed wire a pair of metal strands 20, 21, Fig. 1 (not shown), are advanced by pairs of rollers 22, 22; 23, 23; 24, 24; so that they form a V gap in advance of the weld point w where they are brought together by pressure rollers 26, 27. High-frequency current of at least 50 kc. per sec., e.g. from an oscillator, is supplied in pulses to a pair of contacts 29, 30 engaging the strands ahead of the weld point so that current flows to and from the weld point and effects spaced welds 40. The members 20, 21 may have different sections, of different metals, e.g. different steels or one or both may be of galvanized wire. One of the strands is then sliced through preferably angularly at 41, Fig. 2 (not shown), to form bars elements 42. The prongs of the elements are deflected outwardly in the same or different directions or alternate elements may be deflected in different directions. In a modified apparatus the welded wires are passed between a pair of rotary elements 52, 53, Fig. 7 (not shown), and a pair of rotary elements 60, 61. The element 52 is provided with radially opposite barb cutting and deflecting knives 54, 55 co-operating with cavities 56, 57 in the element 53 to cut and deflect downwardly the forward prong of each barb. The trailing prong on each barb is then deflected upwardly by projections 64, 65 formed on the element 61 to engage in cavities 62, 63 formed in the element 60. In an alternative construction the welded strands pass between a pair of rotating members 70, 71, Fig. 13 (not shown), each carrying diametrically opposed severing knives 72, 73, 74, 75 which co-operate to form a scissors cut.

Abstract: 1,189,241. High-speed cinematography. R.R. CAMPBELL. April 23, 1968, No. 19240/68. Heading G2E. In a high-speed cine camera, film is fed intermittently past exposure aperture 41 by a device 39 comprising a shuttle 73 consisting of two plates 75 spaced on shafts 77, 79 and having fingers 81 to engage the perforations on each side of the film, the shuttle 73 being driven in a circular motion with plates 75 remaining parallel to their initial position such that fingers 81 always have the same inclination to the film. Motor 33 drives shafts 77, 79 through gears 57, 87, cranks 97, 99, two shafts 101, 103 and two further cranks 105, 107 which are 90 degrees out of phase. A registering pin (109), Fig.9 (not shown) of U-shape holds the film during exposure and is driven by an eccentric and spring. Both pin (109) and shuttle 73 are manually adjustable. Film is held against an exposure aperture by a pressure member slidable within holding means (43) and containing a prism which is intermittently urged against film pressure plate (142) by eccentric (119) and spring (121). The prism permits viewing of the image formed at the gate during preliminary camera adjustments. The shutter comprises front and rear sectored discs (151, 155). Fig.14 (not shown) and mounted respectively on a shaft (159) keyed to a surrounding tubular shaft (161). Shaft (161) is slidably keyed to a sleeve (163) with a helical (165) gear engaging a driving gear (167). The size of the shutter openings is variable during rotation by axially shifting sleeve (163) to give relative rotation of the two discs (151, 155) due to gears (165, 167). Dissolve and fade effects are thus possible. Drive is transmitted to the single film sprocket 37, Fig.4, from motor 33 through shaft 55 and planetary gear system 61. Gear 67 drives the take-up spool (31), Fig.13 (not shown), through a belt (199), pulley (201), star-wheel coupling (202, 204, and 206) and shaft (203). The supply spool (49) is freely rotatable on a tubular shaft (205) surrounding shaft (203). A brake band (209) passes round a drum (207) and is attached to a spring-loaded pivoting bracket carrying a filmguiding roller. An event synchronizing means (51) Fig.19 (not shown) by which external events may be triggered at a predetermined point on the film-run, comprises a film-coil sensing feeler arm (237) whose rotation about tube (241) turns a hub with teeth (257) which engage a gear to which a footage indicating needle (261) is attached. A manually adjusted needle (267) carried on a cam-bearing hub is set to the desired point on the footage scale, and a sensing arm within the hub carrying teeth (257) is tripped by this cam to actuate an event triggering switch (299) by axial displacement of shaft (293). Timing marks are provided on the film by means of a pulsating neon light.

Abstract: 685,121. Stator winding machines. HOOVER (ELECTRIC MOTORS), Ltd., and WICKHAM, A. H. July 5, 1950 [July 25, 1949], No. 19515/49. Class,35. In a stator winding machine in which the stator is moved angularly to enable a needle reciprocating through its bore to lay wires in different slots for each direction of its travel., stationary guiding members are provided near each end of the path of the needle for holding the wire toward the bottom of the slots. As shown in Fig. 5, the stator holder B<SP>2</SP> is adjustably secured to the annular pinion B<SP>1</SP> supported on rollers D<SP>1</SP> the pinion B<SP>1</SP> being turned by a toothed rack reciprocated through a variable ratio lever from the follower of a high-speed cam M (Fig. 3). The amplitude of the rack is variable by a slow speed cam drum, the effective surfaces of which are strips the extent and spacing of which depend on the numbers of turns to be wound and the slot spacings of the several coils of a winding, the low-speed cam being linked through pawl-and-ratchet gearing with the high-speed cam. Above and below the stator holder are guide cylinders J fitting over the needle head guides G and having slots J<SP>3</SP> through which the needles C can pass near the ends of their outer strokes, the open ends of the slots J<SP>3</SP> being curved to cause the wire from the needle to ride round the cylinder surface in an arcuate path. The needles C are side-by-side in needle head H mounted on guide-bars G which have cam slots G<SP>1</SP> to receive rollers C<SP>2</SP> carried on the needles so that as the head is moved up the bars G the needle tip is first withdrawn radially as it passes through the stator and is then reprojected after traversing the stator, a similar movement occurring as the needle head travels downwards. Pulleys H<SP>1</SP> on the needle head guide wire to the apertures through the needles. The head is reciprocated by a connecting-rod K<SP>3</SP> coupled to the main shaft of the machine. Before winding commences, a pin X is placed in a slot near the centre of the coil to be first wound, the said slot being one to be wound at a later stage, the pin occupying the half of the slot to be wound last in the case of a doublelayer winding. These pins, of which there is one per hole, assist in the location of the end portions. The two slots nearest the pin are first wound, after lowering the upper guide cylinder over the pin extensions (Fig. 5) then the next two until the windings for a pair of poles has been completed whereupon the machine is automatically stopped. The operator then rotates the stator holder (throngh 90 degrees in the case of a four-pole stator), resets the slow-speed cam drum and starts the machine in the opposite direction. A similar procedure is adopted for the starting winding which occupies the other halves of the slots. Specification 685,199 is referred to.
