Abstract: 1,048,641. Buckles. A. S. STEINBERG, E. BARATTO and G. MATTEINI, [trading as A.C.F.A.-SOCIETA IN ACCOMANDITA SEMPLICE DI ADALBERTO STEINBERG & C.] April 30, 1963 [June 13, 1962; July 7, 1962; July 27, 1962], No. 16995/63. Heading E2A. [Also in Division A3] A buckle comprises a movable frame 5, the side bars 6, 7 of which form guides for side bars 10, of a stationary frame 1, holding the frames together and allowing displacement of the movable frame with respect to the stationary frame in the direction of the side bars, the movable frame having an end bar 14 and an intermediately positioned cross bar 12 with an engaging lip 13 and the stationary frame carrying a roller 3 for a strap, placed between said intermediately positioned cross bar and said end cross bar 14 and adapted to co-operate with the said engaging lip of the intermediately positioned cross bar to clamp the strap between said roller and said engaging lip. The stationary frame is intended to be fastened to a shoe by securing a cross bar 4, at the opposite end of the frame to the roller, to the shoe so that in use the pull exerted in the longitudinal direction by the strap on the movable frame 5 slides it in a direction which moves the lip 13 towards the roller 3 so that the strap is positively clamped between the lip 13 and the roller 3. In the construction shown the lip 13 is curved and the roller has a corresponding shape. In a modification however the lip 13 has a flat surface and the roller has a cylindrical central portion and frusto-conical ends and the strap is suitably shaped to engage both the frusto-conical ends and the cylindrical portion of the roller. The stationary frame instead of being connected directly to the shoe can be connected to a loop member which is itself connected to the shoe.

Title: Improvements in or relating to textile spinning machines
IPC: D01H1/02
Filed: 1949-06-28
Abstract: 672,718. Suction end-catchers and cleaners for textile spinning machines. BECHTLER, H. C. June 28, 1949.[June 28, 1948], No. 17095/49. Classes 120(ii) and 120(iii) Broken ends of yarn, dust and fluff are removed from a spinning machine by pneumatic suction nozzles traversed in association with the roving traverse motion by means of' an additional member extending longitudinally of the machine. In one embodiment, a cross-member 12 carrying roving guides 9 is reciprocated by an eccentric 14 and a suction duct 18, flexibly connected through a separator 19 to a fan 20 and carrying nozzles 17, is reciprocated by another eccentric 23, having a radial slot for adjustment of the pivot pin by which the duct 18 is coupled to the eccentric, so that the length of the traverse, which is usually shorter than that of the roving guides, may be varied. Since the traverse of the yarn leaving the drawing rollers often lags behind that of the rovings as they enter the rollers. the eccentric 23 may be arranged out of phase with the eccentric 14. Alternatively, eccentrics 14, 23 may be dispensed with and cam discs with correlated contours substituted. Although the drive to the reciprocating members is preferably from a common shaft, the eccentrics 14, 23, or cam discs may be driven by separate electric motors. In modifications wherein the duct 18 is stationary and the nozzles 17 are flexibly connected to the duct and mounted for reciprocation, a rotary shaft may have transmission ' elements imparting the reciprocatory movement to groups of nozzles, or the nozzles may be attached to reciprocatory cables. If desired, the nozzles and ducts may both be reciprocated and at different speeds. In order to render the bottom front drawing rollers more accessible, the suction nozzles may be mounted to be displaceable from operative position. In one form of nozzle mounting, nozzles 17 may be arranged in groups on funnels 28, Fig. 2, connected by flexible conduits to a stationary collecting duct 26. All the funnels 28 in a spinning machine are secured to the reciprocating crossmember 21. The funnels 28 may be rotated to adjust the distance of the nozzles 17 from rollers 3. In another embodiment, nozzle pipes are flexibly connected to the duct 26 and may be held in operative position by a spring catch. Specification 645,432 is referred to.

In a liquid cooled and fluid pressure operated braking system of the kind including an endless liquid circuit, as indicated by pipes 12, 14 and 17 in Fig. 1, and having connected in series therein a liquid pressure operated actuator, as shown in Fig. 8, having a hollow annular piston 133, acting as a friction member, a circulator pump 10, also connected in series, forcibly, circulates liquid through the circuit, and the pressure therein may be increased to move the piston 133 by an actuator member 7. As shown in Fig. 1, the member 7 is a self-lapping valve operated by means of pressure applied to a brake pedal 30 to apply varying pressures from a compressed air reservoir 5 to the upper parts of liquid reservoirs 18, whereby variable liquid pressures are generated in the two closed circuits shown, over and above those generated by the pumps 10. Pressure from the valve 7 is arranged to operate a pressure switch 28 so that motors 11 driving the circulating pumps 10 are only started when braking is actually taking place. Fig. 3 shows a braking system, according to the invention, for a tractor-trailer unit, members 43 and 44 representing respectively differential area piston devices for the tractor and trailer having compressed air acting above upon liquid below supplied from reservoirs 50. The devices 16 represent heat exchangers for cooling the circulating liquid. In a further embodiment described, the valve 7 controls liquid pressure, instead of air pressure, to vary the pressure in the circulating system. By connecting the valve 7 to the space below the top of the differential pistons in members 43 and 44, vacuum produced by a vehicle's induction pipe may be used to vary the cooling liquid pressure.
