Abstract: 516,221. Time-controlled valves and electric switches. HORSTMANN, B. G., and HORSTMANN GEAR CO., Ltd. May 21, 1938, No. 15200. [Class 135] [Also in Group XXXVII] A time-controlled device such as an electric switch or gas valve of the kind moved by hand from an initial position to another position and at the same time put under the control of a time piece so that after a certain time interval it returns to its initial position is provided with manually operable means whereby the timecontrol may be cut out and the device set in a desired position. The Figure shows the device applied to a gas-cock. A spring or synchronous electric motor driven clock movement is housed in a case below a plate 2 and drives a spindle 6 passing through the plate. The gas-cock is also arranged below the plate 2 and is actuated by a spindle 13 and crank arm 19. A threearmed lever pivoted to the plate 2 at 12 has a manually operable arm 14, an arm 15 connected by a link 18 with the crank 19 and provided with a cam surface 16 adapted to operate a brake 17 stopping and starting the clock movement and an arm 11 provided with a pin 10 adapted to co-operate with a notch 9 in a cam disc 8. This disc which is frictionally mounted on the spindle 6 is provided with a manipulating knob and has a stop pin 28 adapted to co-operate with an adjustable stop 23 on a pivoted member 26. To operate the device the lever 14 is depressed to adjust the valve, remove the pin 10 from the notch and start the clock. The cam disc is turned in a clockwise direction to an appropriate setting and the pin 10 allowed to engage its periphery. After the desired interval the pin again engages the notch 9 and allows the spring 20 to close the valve, the parts 16, 17 simultaneously stopping the clock. If the disc is rotated in an anti-clockwise direction cam surface at the side of the notch 9 operates the threearmed lever to adjust the cock while engagement of the stop pin 28 on the disc with the stop 23 prevents rotation of the disc by the clock movement. The lever 14, link 18 and crank arm 19 are so arranged that by moving the mechanism to the position where the link 18 is on the other side of the spindle the initial position of the valve is changed from the open to the closed position or vice versa. According to the Provisional Specification the stop on the casing may be moved from the path of the stop on the cam disc to permit the spring to be wound up by a continuous turning of the control knob.

Abstract: 1,057,983. Photographic cameras. VOIGTLANDER A. G. April 13, 1964 [April 13, 1963], No.15210/64. Heading G2A. A photographic camera having a cap into which is built a flash-lamp holder, is provided with a hinged cover which encloses the holder and serves to disengage a flash-lamp from the holder. The holder comprises a base 4 secured to the camera body 1 and two contact springs 5 which hold a flash-lamp 8 in position. The cover 12 is hinged to the back of the camera by a pivot pin 13 on which is mounted a spring 16 to urge the cover into the open position (Fig. 1). A section 112 of the cover, extending at right angles thereto, carries at its free end an insulating element 22 of wedge-shaped cross-section. As the cover is hinged into the closed position the element 22 forces the springs 5 apart to release their grip on the flash-lamp 8. A pin 23 which projects from the inside of the cover 12 contacts the flashlamp and forces it from the holder. When the cover is completely closed the pin 23 is gripped between the springs 5 which overcome the action of the spring 16. In a second embodiment (Fig. 8) the ejection of the lamp 8 is effected by further outward pivoting of the cover. The ejector element 26 consists of a part 260 formed with a central opening 27 for the passage of the lamp base, and a part 261 extending beneath the opening 27. A screw projects from the part 261 into a cavity of the holder base and is urged by a spring 28 into the cavity. On further pivoting of the cover beyond the normal open position lugs 32, 33 carried on side walls of the cover abut against the element 26, lifting it so that the part 261 passes between the springs of the holder and forces the lamp 8 upwards.
