Abstract: 912,363. Door chimes. EVERED & CO. Ltd. May 25, 1959 [May 23, 1958], No. 16578/58. Class 13. In a door chime in which a striker 28 (Fig. 1) is caused to strike the gongs 20, 21 in succession when an over-centre mechanism, which is normally biased to one side of its dead-centre position, is actuated by a manually-operated member, the member moves a pair of driving arms 41, 42, one of which drives the over-centre mechanism, whereafter the other arm operates as a stop to limit the motion of the striker 28. The gongs 20, 21 are mounted on rubber bushes 19 carried by pins 18 secured to four lugs 14 on a baseplate 10. The upper two lugs are joined by a bridge-piece 15 (Figs. 1, 4), having a U-shaped bend 16 at its centre, and the over-centre mechanism is a spring- loaded toggle consisting of a spring 22 and an F-shaped plate 26 of which the arm 25 (Fig. 4) is seated in the U-shaped bend 16. This arm has at its free end a lug 32 which lies between the bridge-piece 15 and the base-plate 10. A pivot-pin 35 extending through a lug 34 and the bridge-piece 15 has its cranked upper end located in a slot 36 in the base-plate 10. A lever 39, having two ears 40 which are pivoted on the pin 35, has one edge which constitutes the pair of driving arms 41, 42 located upon opposite sides of the arm 33 of the plate 26, the spring 43 urging these driving arms towards the base-plate 10. A push-rod (Fig. 2, not shown), extends through a hole in the baseplate 10 and is actuated, by a push-button on the outside of the door upon which the baseplate 10 is mounted, to rotate the lever 39 about the pivot-pin 35 against the action of spring 43. The driving-arm 42 then moves the plate 26 over the dead-centre position of the toggle whereupon spring 22 snaps it over and drives the arm 33 of plate 26 into contact with the arm 41. The flexibility of the wire striker-carrier 27 allows the striker 28 to impact the gong member 20, although the plate 26 is stopped by the arm 41. When the pushbutton is released the spring 43 returns the lever 39 to its initial position, the member 41 driving the toggle over dead-centre whereafter spring 22 snaps it over, the side of the spring carrier 24 acting as a stop in this case.

Title: Improvements in or relating to safety devices for motion picture projectors
IPC: G03B21/18
Filed: 1929-05-31
Abstract: 313,439. Sentry Safety Control Corporation, (Assignees of Allen, T. T., Adams, J. F., and Dunn, J. S.): June 11, 1928, [Convention date]. Kinematograh apparatus.-A cut-off shutter is mounted on a shaft carrying a latch and cam, and a swinging control plate, positioned by the keeper of an electromagnet, prevents turning of the shaft when the magnet is not energized, and swings to disengage the latch when the magnet is energized; the control plate has means engaging the cam to hold the shutter in raised position when the magnet is energized ; means enabling the shutter to be released or raised at will may also be provided. As shown, the shutter, comprising spaced plates 26, is carried by an arm 22 secured to a rotatable shaft 18 carrying a, latch 33 which may engage in a notch formed in the casing 11 when the shutter is in operative position..The shaft 18 has a flat portion engaged, when the shutter is operative, by a spring-controlled pivoted arm 104 carrying an electrical contact 122, so as to allow the contact to separate from a contact 123 on a similar arm 106; the initial movement of the shutter engages the contacts and closes the motor circuit. Further movement of the shutter is prevented by the engagement of a catch 86 carried by the shaft 18 with a lug 69 on a control plate 59 pivoted at 64 and pulled by a spring 76. When the film is moving at projection speed, an electromagnet 49 becomes energized through the operation of a centrifugal switch or other means and attracts a pivoted, weighted, keeper or armature 53. The movement of the armature is followed by the plate 59, thus releasing the catch 86 and allowing the shutter to be raised into inoperative position and retained there by the engagement of the edge of a cam 83 with a notch in the plate 59, as shown in Fig. 5. Stoppage of the mechanism, or breakage &c. of the film, causes the magnet to be de-energized with the result that the weighed armature swings and moves the plate 59 so as to release the shutter, and break the motor circuit. The shutter mav also be released by hand either by depressing a button 127, or, from a remote position, by moving a lever 129 bv means of a cord 130. When it is desired to project images from slides, the plate 59 may be moved by pressing a button 139 the end of which engages the plate 59; this movement frees the catch 86 and enables the shutter to be raised.

Title: Improvements in and relating to emergency release mechanism for power driven wringers
IPC: D06F45/18
Filed: 1950-07-06
Abstract: 684,049. Wringers. BRITISH THOMSONHOUSTON CO., Ltd. July 6, 1950. [July 19, 1949] No. 16922/50. Class 138 (ii). In a wringer having a head portion swingably mounted on a wringer post, roll drive gearing of the type biased to neutral (described in Specification 562,164) and means including a handle 32, 33 and a detent 75, Fig. 7, for setting and maintaining the gearing in a driving position, the detent 75 is adapted selectively to be released either by operation of an axially-pushable member, or by swinging the wringer frame about the post to discontinue the drive. The pushable member is constituted by the handle 32, 33 which is rotatable for setting the gearing and is also movable axially (as described in Specification 562,164). A tubular extension 80, Fig. 3, of the wringer head is rotatable relative to a fixed flange 81, rigid with the wringer supporting base, and having indexing holes 82. A lock bolt 83 is pivotally mounted at 86 on the extension 80, and is also reciprocable against the action of a spring 85 from engagement with a selected hole 82 by the action of a manually operable lever 90, the end of which engages a lug 83a projecting from the bolt 83. J-shaped bell cranks 93R and 93L are each pivoted at 86, and are connected at the ends of their longer arms by a spring 100. Each of their shorter arms is formed with a lug 98 which is arranged to engage a horizontal portion 101 of a rod 92, the upper end of which is connected to either of two arms 72, 73, Fig. 7, of the clutch mechanism, which is identical in construction with that described in Specification 562,164 and operates under either rotation or axial push action of the push-bar handles 32, 33 to stop the drive to the wringer rolls. In operation, on pulling on the wringer frame relative to its supporting base, the bolt 83 is rotated due to its engagement with one of the holes 82 and engages a lug on the long arm of one or other of the bell cranks 93R or 93L. The lug 98 of the bell crank engages the portion 101 of the rod 92 and thus raisesthe arms 72, 73 to release the drive-clutch. One of the bell cranks may have a further spring 102 tending to return it to the inoperative position to correct for the action of the torque of the wringer drive motor. Instead of a spring 100 common to the two bell cranks, each may be positioned by a respective spring.
