Abstract: 19,583. Longworth, W., and Stewart, W. J. Sept. 2. Bolts, screwing into place and unscrewing.-A heckling-machine for flax and the like, of the kind described in Specifications No. 17,437, A.D. 1899, and No. 16,010, A.D. 1901, [Abridgment Class Spinning], has a screwing and unscrewing device for the flax holders as shown in Figs. 6 and 8. The screwing and unscrewing spindle Q is driven by bevelgearing r , r . The bevel-wheel r for unscrewing is driven by a spring-clutch r controlled by a forked lever S actuated by a cam S, which also rocks a pivoted lever W to lift the spindle Q when required. The bevel-wheel r for screwing is controlled by a spring-clutch device t and wedge piece t.

Abstract: 19,300. Longworth, W., and Stewart, W. J. Aug. 28. Heckling-machines.-Relates to the transferring- devices of heckling-machines two of which are arranged side by side, and in which the holders are automatically clamped and unclamped and transferred from a main channel to a cross channel, and vice versa, by turntables such as are described in Specifications No. 17,437, A.D. 1899, and No. 16,010, A.D. 1901, and consists chiefly in pivotally mounting the turntables on a stationary part of the framework instead of upon the ends of the rising and falling main channels. The turntable C, Figs. 2 and 4, is mounted on a spindle c supported in bearings c in a bracket c which is rotatably mounted on a stud c carried by a part of the framework B. The turntable receives a holder a from the rising and falling main channel a, which then rises and swings the turntable through a quadrant by means of a connecting-link D, lever d, and bevel-gearing d', so that it comes opposite to the cross channel. By means of a bevel-wheel c keyed to the fixed stud c and a bevelwheel c on the turntable spindle c, a second quadrantal movement is given to the turntable, so that when it comes opposite to the cross channel it has turned the holder from a vertical plane into an horizontal plane. In machines such as are described in Specification No. 17,437, A.D. 1899, this secondary movement is not required and the turntable is bolted to the . bracket c . A safety-clutch device is provided between the lever d and the bevel-gearing d by loosely mounting the lever upon the bevel-wheel spindle d , to which it is connected by the engagement of a V-projection on the lever with a corresponding groove in a spring-pressed disk E, which engages with a key on the bevel-wheel spindle. In a modification, the link D, lever d, and bevel-gearing d are replaced by a bridle-rod connected to the main channel and actuating the turntable bracket by means of a crank on the bracket. In another modification the turntable H, Fig. 10, is fixed to a sector-shaped shoe h mounted to slide in a circular guide h carried by a bracket h pivoted on a spindle h . The stud has an upwardly-projecting twisted strip k engaging with a pair of rollers l carried by a bracket on the main channel a, so that as the channel rises and falls the rollers acting on the twisted strip turn it and the turntable through a quadrant and bring the turntable opposite the cross channel b. By means of a bridle-rod M attached to the shoe h, the secondary quadrantal movement is given to the turntable. A device for transferring the holders from the main channel to the cross channel is shown in Fig. 12. A lever N mounted on a fixed stud n is coupled to the ordinary catch-bar for moving the holder along the cross channel, so that the lever is operated by the catch-bar and moves the holders from the turntable into the cross channel. The lever N also controls another lever n by means of a roller device n , the lever n having a spring catch n adapted to move the holders a' out of the main channel a into the turntable. A device for transferring the holders from the turntable to the main channel has a bell-crank lever o, Fig. 14, pivoted in a fixed bracket o actuated by the catch-bar lever P and adapted to engage with a snug a on the holder a .

Abstract: 122,045. Stewart, W. J., Woolcock, J., and Kruse, H. Jan. 17, 1918. Concrete vessels.-Reinforced-concrete ships are built up of assembled pre-cast complete transverse frames a, Figs. 1 and 4, formed with apertures b through which is laid the longitudinal reinforcements of the stringers, keelsons, deck beams, and other longitudinal members which are all cast in situ, the hull being then completed in situ with its reinforcement interlinked with the frames to form a monolithic structure. Stout transverse or fairing bars g are laid parallel with the edges of the frames a and connected thereto by linking elements d in the form of loops, ae shown, or loose ends bent round the bars g. These fairing bars support the longitudinal bars of the inner and outer meshwork reinforcement, and these in turn support lighter transverse bars. The pre-cast frames are supported on concrete pads h, Fig. 5, recessed therein, as shown, and grouted through a hole h . These pads become incorporated in the bottom slab when the same is cast in situ.

Abstract: 28,652. Stewart, W. J. Dec. 15, Piles; caissons.-A thin shell 1 is provided with a strong annular or conical shoe 2 secured tc it and having a shoulder 3, upon which is driven a heavy tube 4 closely fitting and supporting the thin shell 1. When the outer shell has been driven the required depth, the inner tube is withdrawn and the shell is filled with concrete. A modification is described in which the driving-tube 4 is short, and is driven by a plate covering the upper end.

Abstract: 117,504. Stewart, W. J. July 25, 1917. Concretes of low specific gravity are formed by fixing moulded elements of a shapable material such as vitreous clay, or non-vitreous clay, subsequently receiving a vitreous coating and sanding. The aggregate is prepared by moulding clay in uniform moulds, e.g. of spherical form, burning, glazing to render non-absorbent, and causing sand to adhere to the glaze before cool to produce a rough surface. Such aggregates, in differing forms and sizes, from a quarter to three-quarters of an inch in diameter, are employed with sand and lime to constitute concretes, which, if they are to be moulded, may have the aggregate elements systematically arranged according to size in the mould. The matrix material, such as cement, is caused to flow in from below upwards preferably under pressure so as to displace air and obviate bubbles.

Abstract: 8488. Stewart, W. J. April 8. Piles; piles, driving. - Hollow wooden and other piles, which may, after driving, be filled with concrete, are constructed of stout longitudinal ribs 1 alternating with lighter ribs 2 and connected together, ior example, by means of stays not shown in Fig. 2. A light sheathing 4 of wood or other suitable material is connected to the ribs; and on the outside of the sheathing are secured longitudinal pieces 5 of hoop iron &c., to the exterior of which are fastened hoops 6. The shoe, which consists of a baulk of timber 7 having an iron or steel point 8, is attached to the ribs 1, 2, and the sheathing 4 and vertical pieces 5 may also be brought down over the shoe. The pile is driven by means of a core provided with fixed or adjustable horizontal or longitudinal ribs which contact with the lighter ribs of the pile. Fig. 8 shows a hollow core 10 with ribs 11 which are made to collapse inwardly by means of toggles 16 operated by a rod 17. Fig. 6 shows a solid core 10 projecting through the bottom of a pile and provided with shoulders 12, as described in Specification 7454/09, or with projections 14, 15 for assisting in pulling the pile downwards.
