Abstract: 711,337. Discharging vertical retorts. DIDIERWERKE AKT.-GES. Dec. 12, 1952 [Jan. 26, 1952], No. 31579/52. Class 51 (2) A bottom closure arrangement for an intermittently operated externally heated vertical retort or chamber comprises the combination of a bottom door adapted to close the bottom aperture of the chamber in a gas-tight manner, a separate lining member which overlies the bottom door when closed but is supported independently thereof and which constitutes a platform at a level in the region of the lowest chamber wall heating flue for supporting a charge in the chamber and means for withdrawing the lining member in a substantially horizontal direction to a position clear of the bottom aperture.. In the embodiment shown the bottom aperture of the coal distillation chamber 1 is closed by the combination of a door 2 and a slightly sloping lining member 3. The latter comprises a block 3a of refractory material mounted in a cast iron frame 3b supported on bearing surfaces 5 which are formed on cast iron members 6 detachably secured to the metal frame 7 which underlies the chamber walls. The bottom door, which when closed engages the sealing edge of a door frame 10 and is provided with a hood 12, hinges about an operating shaft 8 a latch 9 being provided for closure purposes. The member 3 is withdrawn through an aperture 13 formed in the front wall of the chamber this aperture being normally closed by a door 14 which is secured to the frame 3b. A pair of rails 15 receives the member 3 as it passes outwardly through the aperture rollers 16 being mounted on the member for this purpose. An endless cable 17, passing round driving pulley 19 and idle pulley 20, moves the member a counterweight 22 assisting in the withdrawal. The pulley 19 is driven by suitable manual driving mechanism 21.

Title: Improvements in and relating to coin-freed markers for games

Filed: 1945-12-06
Abstract: 603,766. Coin-freed billiard markers. BREAKWELL, E. Dec. 6, 1945, No. 32969. [Class 27] Coin-freed mechanism is arranged to release a push-rod 27, or other operating member, which sets free score indicators for a period determined by a clock mechanism set in operation also by the operating member. As shown, the spindles 19, 20 of the score indicators are driven through coiled spring belts 15, 16 from pulleys 13, 14 on hand shafts 11, 12. Projecting tongues 43, 48 associated with a bar 46 normally engage the belts to lock the indicators, inward movement of the push-rod 27, after insertion of a coin and through a depending arm 30, displacing the bar to the right to free them. The push-rod is retained by a spring 35 whilst the bar 46 is retained by a pivoted catch 45a. As a precaution against fraud, the indicators are locked temporarily while the push-rod is held in by further tongues 40, 41 on a second bar connected with the push rod, being finally freed for use only when the pushrod has been released and the mechanism brought under the control of the clock mechanism 54. Movement of the bar 46 is transmitted through a lever 50 to a rod 52 which releases a brake from the clock mechanism. At the expiry of the prepaid period, e.g. half an hour, one of a pair of pins 57 on an hour wheel 56 of the clock rocks a lever 58 which releases a spring driven disc 59, a pin 60 on which lifts a bar 65 to release the catch 45a so that the various parts are restored to normal with the indicators and clock locked. The bar 46 is also connected to a switch 47 for controlling a light over the billiard table. A peg 67 on the bar 65 operates a counter. Coin action, weight; coin-discharging mechanism: The push rod 27 is locked by engagement of a pin on it against the end 29a of a slot in a coin lever 23. An inserted coin enters a pocket 22 on the lever and rocks it about its pivot 24 so freeing the pin which, in travelling down an inclined extension 29 of the slot, rocks the lever further to discharge the coin to the till.
