Title: Improved apparatus for applying pressure to assemblies of curved glass sheets
IPC: B32B17/10
Filed: 1959-07-07
Abstract: 858,578. Laminating. FORD MOTOR CO. Ltd. July 7, 1959 [July 17, 1958], No. 23269/59. Class 140. An apparatus, for applying pressure to curved glass sheets to be laminated, comprises a frame and a rolling assembly supported therewithin, said assembly comprising a plurality of opposed pairs of freely rotatably elastomer roller components arranged across the frame to press on the sheet in a direction substantially in or parallel with the plane of the frame, as the sheet passes through the frame, the roller components of each pair being movable along the line on which they apply pressure independently of the roller components of any other pair. As shown, an inner frame 26 is pivotably mounted in the base structure 11. Two rows of rubbercovered rollers 75 and 78 are mounted in yokes on the ends of shafts 54, which are slidably mounted in the frame 26. The rollers are 'pressed towards one another by springs of which one end of each is connected with the adjustable tension-plate 62 on the shaft 54, and the other end with ears 68 on the frame 26. Air or hydraulic cylinder devices may be substituted for these springs. A gap in the lower row of rollers 78 is occupied by a driving-unit 79 comprising a cylindrical hub provided with a layer of rubber divided into two sections. Between these sections is a sprocket driven by transmission means (not shown) from the electric motor 111 mounted on the frame 26. The frame 26 may be held stationary by the straps 118, or these may be removed and the frame and all that it carries rotated by means of the hand wheel 117, or by power-operated means. Stops may be provided to limit this rotation. Specifications 708,702 and 774,067 are referred to.

Title: Mechanism for handling elongated articles, such as tubes, bars or the like
IPC: B21B43/00
Filed: 1957-07-24
Abstract: 817,198. Roller conveyers. SALEM-BROSIUS Inc. July 24, 1957 [Oct. 19, 1956], No. 23412/57. Class 78 (1). Elongated articles, such as pipes, travelling along a roller conveyer 2, Fig. 1, are transferred by ejectors 19 to an inclined bed 3 consisting of parallel rails 4 down which they roll to its lower end where they are transferred to a roller conveyer 5 by pushers 36, Fig. 5. Each ejector 19 is fast on a shaft 8 which carries an arm 9. These arms are connected by a link 10, which is connected by a lever 13 to the piston 16 of a cylinder 17 actuated by fluid pressure. Each ejector has an inclined upper surface 21, Fig. 4, down which the pipes slide towards the bed. An arm 24, mounted on a shaft 23 situated between a pair of rollers 2, projects upwardly into the path of the tubes. This arm, when engaged by a tube, turns against the action of a spring to cause fluid to be admitted to the cylinder 17 to raise the ejectors to operative positions. At the lower side of the bed a series of rods 26 is mounted slidably in the framework between the rollers 2. Each rod carries a stop member 27 which limits the movement of the tubes down the bed. Each rod is pivoted to an arm 68 fast on a shaft 69, the position of which can be adjusted by turning a handle 30. An arm 54 fast on the shaft 69 is connected to an adjustable link 56 which is pivoted to one arm of a bell-crank lever 59. The other arm of the lever is pivoted to a slidable member 63 which is in the same vertical plane as an arm 49 fast on a shaft 48. The end of the slide 63 is stepped at 65, the steps acting as stops to limit the movement of the end 66 of the arm 49. Another arm 47, fast on the shaft 48, is pivotally connected by a pin 45 to a tube 35 which is mounted slidably in a fixed guide 34. A rod 36 mounted slidably in the tube 35 is connected by a loose pivotal connection 38 to an arm 39 fast on a shaft 37. Another arm 40 on this shaft is connected to a fluid-actuated piston-and -cylinder mechanism 43. The arm 49 is connected to a similar mechanism 52.

Title: Improvements in or relating to silencing devices for internal combustion engines
IPC: F01N1/16
Filed: 1928-08-14
Abstract: 295,652. Wilman, Z. Aug. 16, 1927, [Convention date]. Exhaust silencers.-The exhaust gases are divided into two parts, one of high pressure, which traverses a closed valve chamber of small volume and thence passes into a silencing chamber, and another of lower pressure which passes either into another silencing chamber or direct to the atmosphere. The engine exhaust passes through a conduit 2 to a central chamber 1 two of the walls of which have. apertures controlled respectively by valves 3, 4 mounted on a common spindle 5 loaded, so as normally to open valve 3 and close valve 4, by a spring 6. The first rush of exhaust passes through chamber 1. valve 3 and conduit 8 to fill the silencing chamber 9. Subsequently, equilibrium is established and the spindle 5 is moved to close the valve 4 and open valve 3 thus permitting the exhaust gases of lower pressure to issue through apertures 10 either to the atmosphere or another silencing chamber. The valves may be actuated positively from the engine.
