Patent GB-1008758-A (GB)
Title: Knitting machines
IPC: D04B15/88
Filed: 1962-04-26
Abstract: 1,008,758. Knitting. SCHUBERT & SALZER MASCHINENFABRIK A.G. April 26, 1962 [May 12, 1961], No. 15938/62. Headings D1C and D1K. Each loop of the first course of a fabric knitted on a straight-bar into machine is engaged by one of the hooks of a welt bar which is then operated to draw off the fabric. Alternatively when knitting a plain welt on a straight-bar into machine, Fig. 8, the initial course is held on the machine needles and, after half the welt has been knitted on the frame needles, the welt hooks are engaged in the course of loops hanging on the frame needles to draw off the welt which is completed in the usual way. As shown, a welt bar 2, mounted between the needles bars in each division of the machine, slides or runs on rollers between rails 3 and is linked with chains 5 carried on rollers and driven from shaft 7. A cam disc 6 on the main cam shaft comprises a cam 60 and a cam track 60<SP>1</SP> which are engaged by a follower roller 62 on a spring biased lever 61 pivoted on the presser shaft 64. The upper end of lever 61 is connected by a link 65 to a clutch 71 on draw-off shaft 7. When knitting commences a first course of loops is drawn on needles 14 and 15 and cam 60 deflects lever 61 so that link 65 causes the clutch 71 on shaft 7 to engage which causes shaft 7 to be turned by 65 so that the welt bar 2 and hence the hooks 1 thereon are advanced to engage the loops on needles 14 and 15. As follower 62 rides down cam 60 clutch 71 is released and the roller is shogged on to the circular cam 60<SP>1</SP>. When bar 2 is advanced a stud 57 on chain 5 engages a spring biased lever 58 which retracts the bar so that the hooks engage the loops as follower 62 rides down cam 60. The fabric is drawn off as the chains 5 are retracted driven from shaft 7 which is rotated by a ratchet and pawl arrangement. Just before the blank is completed, cams 21 strike the followers 22 of stripper 24 which pushes the fabric off the hooks. The end of the fabric is then cast off the needles and an auxiliary motor 25 returns bar 2 to its starting position. Hooks 1 are inclined to the plane of the bar 2 at an angle # and should engage the yarn at an angle α of about 90 degrees. Alternatively the hooks may be latched needles with oblique latches. Clutch 71 comprises a chain which embraces a disc on shaft 7, Fig 13 (not shown). A similar locking device, Fig. 14 (not shown) may be provided to prevent the bar 2 from dropping back when in its starting position. Specification 928,951 is referred to.

Title: Reciprocatory pumps and motors and hydrostatic transmissions of power
Inventor: SLIMM VICTOR ROY
IPC: F01B3/10
Filed: 1963-04-24
Abstract: 1,018,575. Hydrostatic transmissions. FORD MOTOR CO. Ltd. March 2, 1964 [April 24, 1963], No. 16228/63. Headings F2C and F2D. [Also in Division F1] An hydrostatic transmission (Fig. 1, not shown) comprises a pump 3 and a motor 5, each having a swash plate 23 of adjustable inclination to vary the speed ratio and direction of rotation. The swash plates are adjusted by a linkage comprising a crank 83, Fig. 4, rotatable by a servomotor or by hand, and connected to the pump swash plate by a rod 97 and to the motor swash plate by a rod 95. To increase the speed ratio, initial clockwise rotation of crank 83, from its neutral position shown, tilts the pump swash plate without substantially affecting the motor swash plate. When the pump swash plate is near its maximum tilt, further rotation of crank 83 causes movement of the motor swash plate nearer its zero displacement position. Anticlockwise rotation of crank 83 from its neutral position provides speed ratio variation in reverse drive. The pump and motor valve plates 31 (Figs. 2 and 3, not shown) each have kidney ports 33, 35 communicating respectively with blind ports 55, 59 arranged to effect pressure balance of the valve plate, and each cylinder is connected to a source of high or low pressure as it traverses the lands between the kidney ports, to reduce forces tending to tilt the swash plate. In operation of the pump (Fig. 2, not shown), a cylinder moves out of register with low-pressure port 33 and into register with passage 63 on blind port 59 and is pressurized. Beyond the B.D.C. position, the cylinder moves out of register with passage 63 and into register with passage 67 on high-pressure port 35, and then directly with port 35. The arrangement is such that pressure change in the cylinder is approximately linear. In operation of the motor (Fig. 3, not shown), each cylinder registers with a T-shaped passage 73 or 75, after moving out of register with a kidney port, passage 73 being connected to an independent high-pressure source, and passage 75 to atmospheric pressure via the motor casing.

Title: Improved method and devices for the salvage of sunken ships
IPC: B63C7/16
Filed: 1921-06-17
Abstract: 165,042. Hasselberg, B. A. L., and Ostberg, K.. G. June 18, 1920, [Convention date]. Wire couplings.-Relates to apparatus for raising sunken ships of the type in which floats carrying guide-lines are released from the ship, and comprises a form of automatic coupling by means of which lifting.cables are connected to the ship. The float carries a length of thin wire coiled within it, which as the float rises, runs out against a resistance so that the wire is kept stretched. The lower end of the wire is secured to the coup: ling member 3, Fig. 3, which is attached by a chain to the framing of the ship. The lower coupling member consists of two concentric sleeves with internal flanges. The upper coupling member 7, secured to a guide line, is threaded on the float wire, and lowered till it engages within the sleeve 13. Freely movable balls 28 are housed in pockets 29 in the member 7 arranged askew with respect to its axis and so shaped that the balls may project but cannot fall out. Helical springs may be arranged behind the balls. The member 7 thus freely enters the sleeve 13, but on passing the flange 19 the balls fall outwardly and lock between spherical recesses in the pockets and the hollowed underside of the flange 19. The coupling member 12, to which is attached by means of the eyes 22 a lifting chain, is then threaded on the guide line and lowered to engage with the sleeve 3, the upper part of the member 7 being coned to assist the engagement. Locking is effected by means of the balls 25, the action being the same as that of the smaller coupling. If necessary, two or more guide-wires may be employed before the final lifting chain is lowered, further couplings being arranged concentric with the first. The Specification as open to inspection under Sect. 91 (3) (a) also describes a modified form of coupling of general application, shown in Fig. 5 (Cancelled), in which spring-pressed balls 37, housed in pockets in the sleeve 35 engage in recesses in the head 33. Between these recesses the head is cylindrical, so that disengagement may be effected by relative rotation of the members. In a further form of this modification, the balls are housed in pockets in the head, and engage in recesses in the sleeve. It is also stated that the locking balls in the form shown in Fig. 3 may be replaced by rollers or clutch teeth. This subject-matter does not appear in the Specification as accepted.
