Title: Improved Reed-release Motion for Power-looms.
Inventor: JACKSON WILLIAM
IPC: D03D49/68
Filed: 1918-03-27
Abstract: 122,330. Jackson, W. March 27, 1918. Addition to 5550/15. Loose-reed motions; stop-motions, shuttle. - The reed-release motion described in the parent Specification is modified by the use of a system of interconnected levers for transmitting the movements of the swells to the reed-releasing daggers instead of a one-piece wire lever device. The plates B, Figs. 1 and 7, on which are pivoted the box castings A carrying the reed-case M, are extended downwards to form brackets B<1>, on which are adjustably pivoted levers F<1> of the shape shown in Fig. 4, and these levers are connected by rods, chains, &c. V<1>, V, V<2> to one another and to levers F pivoted on bearings O at the back of the lay K. Levers C secured to the stop-rod E have integral projections P engaging slotted parts of the castings A, and levers C<1> with slots from front to rear and from side to side also are secured to the stop-rod and engage the release daggers D and projections P<1> thereon. If the shuttle does not enter the shuttle box, the daggers are not raised by the levere F<1> and engage castiron buffers L, adjustably secured to two-part brackets H, and the rear ends of the daggers turn and slide down the levers C' against the action of springs W. When this occurs, the projections P on the levers C pull down the castings A and release the reed N. A hand-lever on the stop-rod is used to replace the parts and is connected by elastic means to the weft fork to hold this down when the reed is released and thus to stop the loom. If the shuttle enters its box, it pushes out an arm G, Fig. 3, of a lever pivoted on the swell U so that the other arm G' of the lever acts on one of the levers F and turns it to one side, so that, through the connexions, the levers F<1> are turned to cause their lower projections to raise the front ends of the daggers D above the level of the buffers L. In a modification, the swell acts on a projection or adjustable screw on one arm of a bell-crank lever pivoted at the back of the shuttle box, the other arm being connected to a bent lever used in place of the lever F. In a further modification, the swell U, Fig. 12, acts on an arm G secured to the upper end of a shaft F. to the lower end of which is secured an arm G<1> to which the connexion V<2> is adjustably secured.

Patent GB-832044-A (GB)
Title: Improvements relating to self-energizing brakes
IPC: F16D55/46
Filed: 1958-02-21
Abstract: 832,044. Disc brakes. DAIMLER-BENZ A.G. Feb. 21, 1958 [Feb. 28, 1957], No. 5716/58. Class 103 (1).  A self-energized brake is characterized by two operating members acting on a movable brake shoe, the first being such as to act in a direction to the brake surface which remains the same and the second operating through a self-adjusting mechanism such that its direction of action varies automatically in dependence on the coefficient of friction of the braking surface. In Fig. 1, the shoe 12 slides on a carrier 13, 14 carrying a fixed shoe 11, against the disc 10 under the action of connected actuators 15, 16, the piston-rod 22 of actuator 15 having a ring- sector shape extension engaging a tooth 23 on the shoe and on movement of the shoe in the direction of rotation of the disc the rod 22 rocks so that the force exerted by the actuator 15 is always along the axis of the piston 21. The piston-rod 25 of actuator 16 comprising cylinder 24, engages a socket member 26 pivoted to carrier 13, 14, a further socket member 29 being provided on a shoe 12 and a ball 28 being included between the socket members whose cavities may be spherical, ellipsoidal, &c. The ball 28 is deflected on movement of the shoe 12 according to the coefficient of friction of the disc surface, a greater deflection for greater coefficient of friction and the greater the angle from normal of the direction of the self-intensification force, hence the force perpendicular to the disc decreases for greater coefficient of friction and vice versa, the selfintensification thereby varying according to the coefficient of friction. In the arrangement in Fig. 2 (not shown), the actuator 16 is inclined to the disc surface and acts on the socket member 26 which may be pivoted to the long arm of a two-armed lever, the short arm being pivoted to the shoe, the lever being actuated manually by a cable for parking and provides a greater sensitivity to changes in coefficient of friction. In Fig. 5 (not shown), an arrangement keeps the ball in an off-centre position when the brake is not in use corresponding to the normal average coefficient of friction, and in Fig. 6 (not shown), the pistonrod of the actuator 16 is pivoted to an intermediate lever engaged by a pin on the shoe 12, this lever adjusting its angle to the braking surface according to the coefficient of friction.
