Title: Improvements in or relating to straight-bar knitting machines
IPC: D04B11/00
Filed: 1947-12-13
Abstract: 655,048. Knitting - machines. SOC. ITALIANA E. BREDA PER COSTRUZIONI MECCANICHE. Dec. 13, 1947, No. 32909. Convention date, Dec. 13, 1946. [Class 74 (ii)] On axial displacement to the left of the cam-shaft 1 of a straight-bar knitting-machine, the driving half 2 of a dog clutch, transmitting the drive to the reciprocating motion driving pinion 7, bears against a roller 13 on a slide 14, so compressing an adjustable spring 16 and hence, at a predetermined stage, moving another slide 11 to the left, against a weaker spring 12: the slide 11 carries with it a surface 17 which, after disengagement of dogs 3, 4, brakes the driven half 5 of the clutch and a spring-urged member 18 which engages a notch 20 in and locks the part 5.

Title: Improvements in gyroscopic apparatus for indicating angular movements
IPC: G01C19/38
Filed: 1931-11-27
Abstract: 382,782. Gyroscopic apparatus. FRIEZ & SONS, Inc., J. P., Baltimore Street, Baltimore, U.S.A. Nov. 27, 1931, No. 32925. Convention date, Nov. 28, 1930. [Class 97 (iii).] In a gyroscopic turn indicator, a fluid pressure actuated device is provided for centralizing the gyro about its axis of precession and for damping its oscillations. The device may be actuated by the fluid used to drive the gyro. In the form shown, the rotor 5 is mounted for rotation about an axis X-X in the ring 6, which is mounted to oscillate about the axis Y-Y, corresponding to the longitudinal axis of the vehicle, in the airtight casing 3. Opposite ends of the ring 6 are connected by chains 19, 20 to a bell-crank lever assembly including the arms 23, 24 and lever 22. When the vehicle turns about the axis Z-Z the gyro precesses about the axis Y-Y, actuating the pointer 7 through gearing 11, 12 and pulling on one or other of the chains 19, 20, thus rocking the lever 22. In order to apply a restoring force to the gyro the lever 22 is connected to a piston 30 working in a cylinder 34 from the inner end of which air leaking past the piston is exhausted by the pipe 18 connected to a Venturi tube. The cylinder is tapered so that the restoring force is greatest when the piston is in the outermost position. The gyro is driven by air sucked in to the casing 3 through the pipe 17. A byepass valve 33 may be provided to adjust the sensitivity. The piston 30 and cylinder 34 in addition to providing a centralizing force also serve to damp the oscillations of the gyro. When the supply of fluid ceases, both the damping and centralizing forces are suspended and the failure of the instrument may be detected by the unrestrained fluctuations of the pointer 7.

Abstract: 637,713. Pressure-relieving devices for fluids ; valves. MALTERRE, F. R. Dec. 5, 1945, No. 32925. Convention date, Aug. 23, 1943. [Class 135] A valve for the control of liquids, having a closure member 3, Fig. 2, formed at one end of an operating rod and co-operating with a seat 10, is characterized in that the rod is hollow and contains a gaseous medium to absorb shocks caused by closure of the valve. A pressure gauge may be connected to the hollow space in the rod for measuring the rate of flow of the liquid, the space being subjected to the total head of the liquid passing through the valve. Oscillations may be damped by providing a closure member which extends across the lower end of the space in the rod and is provided with a number of apertures controlled by a spring-loaded disc arranged to permit the flow of liquid into the space in the rod relatively unrestrictedly, but to limit the rate of outflow therefrom. Modifications are described in which the space in the rod is sealed from the controlled liquid either by a resilient diaphragm at the lower end of the space or by being enclosed in a resilient bellows 16, Fig. 8. Fig. 6 shows the invention applied to a valve comprising a hollow operating-rod 1 passing through a stuffing-box 57 and actuated by a cap 50 having screw-threaded engagement with the housing. The rod may be modified by flaring the lower end thereof and providing strengthening ribs between a flange 2 and the rod proper. The operating-rod may be made, e.g. of metal, pottery, glass, synthetic plastic material or wood.

[Class 83 (iii).] In a portable automatic tube-cutter, a body has a pair of oppositely aligned tubular bosses in which are mounted brackets carrying V-shaped clamping members for the tube, adjustable to and from each other, the toolcarriers being movably guided within the brackets. The device comprises a body 1, flanged at 2 and provided with bosses 3 which support the guides and cutters and the operating handles 24. The V-guides 8 are secured by screws 9 in similarly shaped brackets 6, 27, the former being integral with the body 1 and the latter formed on a stem 22 slidable in the boss 3 and guided by a spline 26 and a screw 25a. A tool-carrier 11 is slidable against a flat face 10 on the boss 3 and has a stem 12 located in the boss and normally pressed outwards by a spring 13 engaging a collar 14 which is fixed in the boss to provide a guide for the stem. A cutter 18 is adjustable in the carrier by the head of a screw 17 engaging a slot in the cutter and is clamped by a screw 38. A similar tool-carrier 30 has a stem 31 slidable within the stem 22 and is pressed outwards by a spring 33, the stem 22 being adjusted by a left-hand thread thereon engaging a sleeve 21 which screws in a right-hand thread in the boss 3 and is rotated by handles 20. In operation, the handles 20 are manipulated to cause the V-guides 8 to engage and centre the tube to be cut, the toolcarriers being forced backwards against their springs by the tube. The body 1 is then rotated round the tube, the cutting feed being applied by the springs 13, 33. The depth of cut is limited by stops 15, secured to the tool-carriers by screws 16, and located in recesses so as to project towards the axis of the work slightly less than the cutters and run in the groove formed by the cutters. In a modification the body 1 is formed in two parts which are adjustable relatively to each other, to accommodate tubes of different sizes, by a right and lefthand screw and are guided by a rod parallel with the screw, the bracket 27 then being non- adjustable in the boss 3.
