Title: A device for gripping and cutting off the inoperative threads in circular knitting machines
IPC: D04B35/00
Filed: 1954-03-16
Abstract: 782,569. Knitting-machines. ZAPADOMORAVSKE STROJIRNY NARODNI PODNIK. March 16, 1954 [March 16, 1953], No. 7653/54. Class 74 (2). The outgoing one of striping yarns n<SP>1</SP>, n2 is trapped between a rockable clamp 27 and the top face of a stationary member 8 and is cut between an upper cutting edge 10 on that member and a cutting edge 17 on a rockable member 14; and an outgoing elastic yarn e is trapped between a rockable clamp 28 and the bottom face of the member 8, and is cut between an edge 11 on that member and an edge 18 on the member 14. For this purpose, the member 14 is rocked from a central position, in which both trappers are closed, either upwardly to open the striping yarn cutter, or downwardly to open the elastic yarn cutter: in each case, the associated trapper is opened by engagement of member 14 with a pin 33 or 34 on the appropriate rockable clamp, the other trapper remaining closed by reason of a spring 31 which urges both clamps into the clamping position. A rod 35 guides the striping yarn to be severed, under the cutting edge 17. Exchange of striping yarns and their cutting and trapping are controlled by a cam shaft 56 racked round by pawl 121 and ratchet 123 whenever a follower lever 113 is shogged by a pattern or timing chain into the path of a cam 111. At each rack of the shaft 56, cams 100, 101 thereon interchange the swingable striping yarn guides 95, 96 and another cam 55 thereon acts through linkwork, including a lever 48 and tie rod 23, to open and close the striping yarn cutter and trapper. The elastic yarn guide 79 is swung into and out of action, along a slot 82, by reason of a segment 87 on a control drum 70, which segment acts through two-armed levers 89, 90, link 93, lever 85 and link 84. The cutter and trapper for the elastic yarn are operated by another segment 71 on the drum 70, acting through a bell-crank lever 73 and a link 76 to swing the lever 48, and thus the member 14, in the directions opposite to those in which it was swung during exchange of striping yarns. A pin and slot connection 49, 52 provides sufficient lost motion to enable each of the yarn cutter and trapper controls to operate independently of the other. The yarns are shown as being fed to the lower cylinder needles of a superposed cylinder machine.

Title: Improvements in or relating to magnet assemblies which are long compared to their cross-sectional dimensions
Inventor: ROGERS DOUGLAS CECIL
IPC: G05D16/06
Filed: 1953-03-26
Abstract: 742,070. Magnets. STANDARD TELEPHONES & CABLES, Ltd. March 26, 1953, No. 8391/53. Class 35. [Also in Group XL (a)] A magnet assembly producing a rectilinear magnetic field along an axis over a length much greater than the cross-sectional dimensions of the assembly, particularly for focusing the beam of a travelling-wave tube, comprises a plurality of abutting cells stacked along an axis, each cell comprising at least one permanent or electromagnet, together with additional spacing members of low reluctance material, if desired, arranged between a pair of parallel plates of high permeability and low reluctance, the separation between the plates being not more than half the shortest distance through the axis between opposite ferromagnetic cell members. The magnets may be axially magnetized and annular, Fig. 8, 18 being the magnets and 19 slightly thicker soft iron spacers; the spacers may be omitted, Figs. 1-3 (not shown). Plates 17 are also of soft iron. Since the magnetic field is more nearly uniform away from the magnet surfaces, the area of uniform field is enlarged by making the axial length of each cell not greater than half its internal diameter. In modifications, each cell may have two electromagnets of circular cross-section arranged along the longer axis of rectangular plates, Figs; 4, 5 (not shown),.or two permanent magnets 27, 28, Fig. 9, of rectangular cross-section magnetized at right-angles to their lengths, the end plates being unapertured, Figs. 6, 7 (not shown), or apertured, Fig. 9. In general, non-uniformity of the field introduced by apertures in the end plates can be corrected by graduating the magnetic properties of the cells such as the strength of the magnets, e.g. by partial magnetization. The end plates are thicker than the intermediate plates. In another embodiment, Fig. 10, the magnetic cells, each comprising two soft iron plates 46 of square section, two magnets 47 and two soft iron spacers 48, are held between end plates 37, 38 by four tie-rods 39. Member 40 allows for forced air cooling and locating means for the collector 24, and member 42 for mounting and locating the gun end of the tube. The input and output guide connections 29, 33 are mounted on tie-rods 39 and have coupling flanges 49 on one side, and piston matching arrangements 30, 34, Fig. 9, on the other side, of the assembly. The spacers 48 are slightly thinner than magnets 47.

Title: Improvements in machines for making sliding clasp fasteners
IPC: B21D53/50
Filed: 1948-03-22
Abstract: 684,391. Making sliding-clasp fasteners. MORSE, S. R. March 22, 1948 [Sept. 30, 1947], No. 8402/48. Classes 83 (ii) and 83 (iv). [Also in Group XXV] Shearing; stamping. In a machine for punching fastener elements from an intermittently-fed strip and securing them to a tape to form sliding clasp fasteners, means is provided for moving the strip reversely of its direction of feed immediately after shearing to lessen the formation of chips. An electromotor 4 rotates a shaft 5 with eccentrics reciprocating a ram 11 carrying a block 13 with punch 76, female projection forming dies 67<SP>1</SP> and clamp actuating cams 80. Strip feed. The strip 42 is fed from a spool through a guide 27 and between a roller 36 rotated by ratchet mechanism 40 from the shaft 5 and a block 29 urged by a spring 43 towards the roller against pressure of a spring 33. The block 29 is a loose fit in an opening 28 and is urged rearwardly by a spring 31. The ratchet mechanism rotates the wheel 36 to feed the strip forwards and to carry the block 29 against the top of the opening 28. When the ratchet-wheel is freed the spring 31 forces the block downwards to prevent the formation of chips at the shearing tools. A cam lever 35 releases the pressure on the block 29. Tape feed. The tape 43 is fed horizontally with headed edge downwards from spools through spring-pressed friction guides on a mounting 20, Fig. 4, not shown, past the punches by a roller 57 on a shaft 59 rotated by ratchet gearing 61 from the shaft 5. The roller co-operates with a pressure-pad 58. Punches. The die-plate 21 of the top of the strip groove 26 houses a die 67 for forming the depression in the element, a shearing die 68 and a spring-pressed ejector 69. The strip 42 is fed upwardly in the groove 26 and die 67 forms the projection on the element. The pouch 76 cooperating with the die 68 shears an element 87 from the strip with legs straddling the bead of the tape. On continued forward movement of the ram inclined cams 80 engage members 86 to close the legs and secure the elements to the tape. Gap-forming device. In order to leave bare parts in the tape, means is provided for interrupting the formation of fastener elements without stopping the tape feed. To this end an apertured metal band passes between a weighted pulley 93 and freely mounted pulley on the shaft 37 rotated by a ratchet pawl moving with the strip feed pawl 39. Masking plates are selectively secured to the band to mask the pawl 39 and periodically to prevent operation of the strip feed. A friction band is fitted to the shaft 37. The mechanism is duplicated to produce two fasteners during its operation. Specification 684,458 is referred to.
