Abstract: 796,729. Fabric raising machines. HOBE, C. M. VON. Oct. 19, 1954 [Oct. 19, 1953], No. 30061/54. Class 42 (1). In a fabric raising machine, the tension of the fabric is controlled by adjustment of the ratio between the speeds of rotation of externally-driven conveying rollers 2, 4 in accordance with the fabric tension at a location between the rollers so as to keep the tension at a required value; roller 2 is located at the entrance to the machine and roller 4 at the end of the raising path (as shown) or between two raising sectors. Rollers 2, 4 may be driven by gearing from the drum 3 carrying the raising rollers, an infinitelyvariable gearing being included in the drive to roller 2 for speed control purposes. A fabric tensioning arm 11 carrying an adjustable weight 12 is maintained at a given position on a graduated scale by manual adjustment of the variable speed gearing or by automatic adjustment of the gearing through electrical contacts or a piezo crystal associated with arm 11. Alternatively a device responsive to a torque dependent on the fabric tension may be used to regulate the speed ratio of rollers 2, 4. Tension control may be applied at a number of different locations along the fabric travel; the tension in the second portion of the travel may be kept greater than in the first portion by adjustment of the speed ratio between the entrance roller and an intermediate roller and also that between the intermediate roller and the exit roller.

Abstract: 246,277. Bennett, G. H. Dec. 15, 1924. Vacuum closures; capsule and like closures; cap-stoppers, screw; lever lids; stoppers, packing rings for. -Closures for bottles, jars, cans, &c. comprise a thin ring or band of rubber &c., of less diameter than the container at the part where the joint is to be made, which is stretched and placed in a vertical position around the mouth of the container or around the spigot portion of the closure member, the ring being adapted, when the closure is effected, to be bent and compressed between the container and its closure member to form an horizontal # -shaped packing which can easily be punctured to admit air to facilitate the opening of the closure. A flat horizontal ring is stretched around the mouth of the container 1 and placed vertically thereon so that, when the cover 2 is applied, the ring 5 is doubled up to the # -shape shown and is compressed between the flange 3 of the container and the lid which has the lower edge of its flange 4 inturned to prevent the ring from wedging between the lid and the neck of the container. In modifications, a groove is formed on the container or on the spigot part of the closure member for the reception of the stationary edge of the ring and the adjoining surface on which the ring is stretched is convex in vertical section, Before application of the closure, the ring may be doubled on itself by a ring-shaped tool, and when the closure is completed, a protecting band 6 or clips embracing the flanges of the container and closure member may be pro vided, or the closure may be held down by a screw cap.

Abstract: 442,040. Toys. HOBBS, W. J., Forest Cottage, Castle Lane, Southampton. April 15, 1935, No. 30701/34. [Class 132 (iii)] A dart flight is made of hair or bristle secured in twisted wires. As shown in Fig. 1, two lengths of galvanized iron wire 1a are wound on a drum or bobbin 1b and the ends of the wires are clamped between the jaws of a rotating vice 1c of a stranding machine, the drum being braked to keep the wires taut and parallel with each other. A quantity of lightly packed hair or bristle is placed between and at right angles with the wires and the vice is rotated, causing the wires to form a twin spiral strand and the hair or bristle to form a cylindrical brush, the wire being gripped on the side of the brush opposite to the vice to limit the length of wire being stranded. The wire is then cut and the flight inserted in the bored and countersunk body of a wooden dart, Figs. 7 and 8, to which a liquid adhesive has been applied. Fig. 9 shows a sectional view of a dart body having a wood shaft containing the flight set in a socket in a metal body.
