Title: Improvements in sash raising systems for movable windows
IPC: E05F11/38
Filed: 1923-07-27
Abstract: 201,909. Soc. HÚra, (Assignees of Klein, G.). Aug. 5, 1922, [Convention date]. Sliding window opening and closing apparatus; vehicle window opening and closing apparatus.- In operating mechanism for vehicle &c. windows consisting of an endless chain b, Fig. 1, passing over upper and lower sprocket wheels c, d, a rod a' has mounted thereon in a displaceable manner a roller a<3> adapted to engage a groove in a member a<2>, Figs. 1 and 5, secured to the window. The roller a<3> is secured on the rod a<4> bv means of a set-screw a<5>, and, in order to ensure close contact with the grooved member a<2>, a spring pressure member is provided on the rod. When the window reaches its closed position it is forced over the rail at the bottom of the window opening by reason of a bend in the slotted member a<2>. Another method of causing this transverse movement is shown in Figs. 10 and 11, wherein the roller is provided with a helical groove h adapted to be engaged by a pin on a button i formed with a groove i<1> working in the slot a<2>. In this case, when the window is nearly closed, the link e reaches the sprocket-wheel c and the roller begins to turn, which movement causes the button i to move along the roller and push the sash over the rail. The chain b is tensioned by a member b<1> carried by a pivotally mounted and spring-pressed arm b<3>. For locking the window in any position the upper sprocket wheel is provided with a central portion which can only be operated by the handle. The wheel d is provided with a balancing spiral spring.

IPC: B60Q1/124
Filed: 1925-07-30
Abstract: 260,353. Whittle, W. G. July 30, 1925. Switches, mechanical, without quick action; handles.-An arm carrying a lamp is couuected to a support by a joint associated with a switch so that the movement of the arm switches the lamp on and off. In one form a cylindrical boss 5, Fig. 3, on the arm 6 is pivoted on a cylindrical base portion 1 clamped to a cycle handle. The base portion 1 is provided with a fixed semi-circular contact blade 11 and the cvlindrical boss 5 has two normally separated contact blades 7, 8, each having a contact stud, one of which is electrically connected to the lamp bulb so that current is supplied to the bulb only when the stud is in contact with the blade 11. The two blades 7, 8 may be brought into contact by means of a tumbler 13, Fig. 8, so that the bulb remains alight during the whole angular movement of the arm 6. The boss and the base piece are secured together by means of a cap 23, Fig. 3, engaging a vertical stud 24 and by a milled nut 26 engaging the base-piece and forcing a split-ring 25 against the boss 5, the coacting surfaces being protected by a downwardly inclined flange on the member 5. In a second form the joint is provided with an additional switch comprising contact blades caused to contact with one another by means of a tumbler 13<a>, Fig. 8. In a third form, the automatic switch comprises a fixed and curved contact blade concentric with the axis of the boss and a contact pin forming a continuation of the conductor in the arm 6. In any of these forms the arm 6 may be held in the adjusted position by a bent blade spring engaging depressions in projections on the member 5, the spring bearing against the outside of the member 5 when not engaging the depressions.

The substrate is preferably primed metal (e.g. steel), glass, paper or polyethylene film. The microporous layer may be formed of cellulose acetate butyrate or a polymer of ethylene, propylene, hexamethylene adipamide (nylon 66), hexamethylene sebacamide (nylon 610), caprolactam (nylon 6), or vinylidene chloride. Blends or copolymers of the above nylons may also be used, and the solutions may be applied by doctor blade.

Abstract: 290,072. Morris, A. July 21, 1927. Road-traffic signals on vehicles. - An arrowshaped direction signal f is mounted, for movement in a horizontal plane, on an arm c by means of a swivel pin e, the arm c being lifted about a pivot d from a concealed position in a casing a to the horizontal position by pulling a flexible shaft n by means of a handle s. A key device on a plate v engages a guide groove t during this movement, ensuring that the signal f arrives at the outstanding position in alignment with the carrier arm c. By turning the handle s, the signal f may now be turned in either direction in a horizontal plane, through the medium of the shaft n, sprocket wheels k, m, and chain and wire connections 2. A lamp h inside the arrow f is lighted when a contact on a segment j engages a contact blade x. In a modification the flexible shaft n is extended through the arm c and turns the arrow f by means of bevel gears. A red transparent plate 12 may be fitted at the point of the arrow.
