Title: Improvements in electric clocks
IPC: G04C3/02
Filed: 1930-04-16
Abstract: 352,560. Electric clocks: WIRZ, A., 6, St. Albananlage, Basle, Switzerland. April 16, 1930, No. 12044. [Class 139.] In an electric clock wherein the pendulum at each swing releases an impulse lever from a lifting pin, this pin is carried on the core of a solenoid. The core, after release, rotates under the action of a weight to circuit-closing position, whereupon the pin and core are returned to latched position and a ratchet device is actuated to drive the clock hands. The pendulum 7 is hung on a blade 5 and has a projection 13 coacting with a rod 12 on a lever 10 attached by a flexible blade 8 to a pin 9. This lever 10 has pins 15, 14 controlling a pin 17 on the core lever 19 of a solenoid 21. 19 is a permanent magnet and is rigid with its axis 20, with a weight 24 and with a disc 25 carrying a pin 27 which makes electric contact with a lever 29, counterweighted at 30 and pivoted at 28. A disc rigid with axis 20 carries a pawl 34 for driving a ratchet 35 to the clock hands. Pin 27 is electrically connected by a line 26 to a stop 18 on which the lever 10 rests in its lowest position, this lever being connected by line 33 to solenoid 21, line 22 and battery 23. As the pendulum swings to the right it lifts lever 10 and releases pin 17 whereupon weight 24 rotates lever 19 clockwise, carrying pin 27 with it until contact is made at 27, 29. About the same time contact 18, 10 is made and a circuit 32, 29, 27, 26, 18, 10, 33, 21, 22, 23 is closed to energize the solenoid 21. The latter attracts its core 19 and the pin 17, moving counterclockwise, is relocked by pins 14, 15. During this movement contacts 27, 29 break just prior to the opening of contacts 18, 10 by pin 17, to prevent sparking at these latter contacts: 27, 29 is a rubbing contact. As solenoid 21 moves its core 19, and hence disc 25, counterclockwise the pawl 34 drives the ratchet 35. In a modification, Fig. 5, the electrical circuit does not include lever 10. The solenoid 21 is connected directly by blade 26 to disc 25 and pin 27. Lever 29 has a projection 29<11> and has pivoted to it a finger 28<1> coacting with an insulated stud 27<1> on disc 25. When the pendulum swings to the right and releases pin 17, core 19 swings clockwise and pin 2<7>1 presses finger 28<1> and lever 29 to the right so that the extension 29<11> is kept out of the path of pin 27, until the pin 27<1> leaves the end of finger 28<1> and passes under the-latter. Thereupon lever 29 is swung counterclockwise by its weight 30 and the circuit is closed at 27, 29 for solenoid 21 to return the core 19 counterclockwise to locked position. The contacts 27, 29 may also, once each complete pendulum swing, close the circuit for secondary clocks 37 through line 36 and battery 38. Alternatively, the battery 23 may be used for this purpose. Solenoids may act on both ends of the lever core 19.

Title: Improvements in Grenades and like Projectiles.
Inventor: FORREST HUBERT
IPC: F42C14/02
Filed: 1918-07-25
Abstract: 130,727. Forrest, H. July 25, 1918. Projectiles; projectile fuses. - Relates to time-fuse grenades adapted either to be thrown by hand or discharged from a rifle or the like, and consists in means whereby the short fuse . which operates in the case of hand throwing is supplemented by an additional length of fuse interposed between the primer and the detonator when the grenade is to be discharged otherwise than by hand. In the grenade shown in Figs. 1 and 7, comprising a spring striker f controlled by an external lever g, a percussion cap e adapted to be ignited by the striker, and a short time-fuse k leading to the detonator d, a rotary ring h carrying a supplementary time-fuse h<1> is provided. Ports i, i'; i<2>, i<3> are formed in the central plug h<2>, and are so arranged that, when the ring h is set in one position, the flash from the cap e is transmitted to the fuse h' and thence to the fuse k; with another setting of the ring h, when the grenade is to be thrown by hand, the fuse h<1> is cut out, and the flash passes directly to the fuse k. In a modification, the change in the effective length of fuse is made automatically when the grenade is projected from a rifle or the like, one of the passages being closed, in this case, by the set-back of a plug. A ring b is formed on the outside of the grenade body to enable it to be projected from a discharger.

Title: Improvements in apparatus for measuring and delivering liquids
IPC: B67D7/60
Filed: 1928-04-30
Abstract: 318,183. Bremner, D.O., and Watson, G. W. April 30, 1928. Measuring-devices; priming; locking and releasing devices.-In a measuring pump of the kind described in Specification 313,203, in which the visible chamber is primed by the pump without causing the totalizer counter to operate, the sales counter is rendered inoperative during priming either separately or jointly with the totalizer counter. This may be effected by opening a clutch 24, 25, which drives the counters 26, 49 through a gear train, the opening being effected by a cam on the rod of the diverting valve when the latter is set to the priming position. Means to prevent the valve from being moved from one setting to the other, unless the pump is at starting position, comprises a plate 44 carried by the valve rod 20 and provided with a slot 45 through which the pump rack 2A slides, so that the plate cannot move unless the rack is at bottom position. The pump cannot deliver to the discharge hose until the hose nozzle is removed from its support. The support 59 for the nozzle 60 is connected by a rod 58 and lever 57 to a eliding bolt 55 which fits a specially shaped slot in the plate 44 carried by the valve rods 20. When the nozzle is removed from the hook, a spring 56 withdraws the bolt and allows the valve to be set to discharge position. The priming of the weir chamber may take place while the totalizer counter is operative, if a second counter is used to record the priming strokes, the difference between the readings on the two counters giving the quantity delivered. The priming counter is made inoperative when the valve is set for delivery by means .of a double sliding clutch which drives the sales counter and the priming counter alternatively according to the setting of the valve. The sales counter and/or the totalizer counter may be incorporated in the same structure as the valve and weir chamber. The valve may slide or rotate, and may be loose coupled to its shaft to enable it to seat correctly. The weir chamber 72 may be obscured during priming by a shutter 71 operated by the valve rod 20 through gearing 69, 70.

Abstract: 543,104. Electric signalling systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., COCKERELL, C. S., and TOOLEY, M. D. Aug. 8, 1940, No. 12748. [Class 40 (i)] In an arrangement for tuning wireless sets, a disc J which is coupled to the tuning condenser C and which carries in concentric grooves a number of pre-adjusted stop members D for co-operation with levers M is driven in response to a setting operation from a main shaft F through a friction clutch H to wind up, a driving spring K until a'datum position is reached, whereupon a pin coupling X, W becomes operative, the friction clutch slips and the shaft F drives a cam shaft Q to bring an appropriate lever M into the path of the corresponding stop D. The shaft Q also drives a rotary switch R which is inter-connected with the manual setting switch S1, which may be remotely situated, in such a way that the clutch B between the motor A and the shaft F is engaged, or alternatively the motor A is energized, as long as the two switches are out of register. When the motor drive ceases, the spring K comes into action to drive the disc J and the condenser C in the reverse direction under the control of a governor L until a stop D strikes the selected lever M, this movement being transmitted through the friction clutch H to withdraw the pin X from its associated pin W to allow for the preliminary movement of the disc J to its datum position at the next setting operation. The shaft Q carries a starwheel S which co-operates with a pin on a spring- pressed lever T so that the shaft is jerked forward ahead of the drive into each operative position. Wave-changing switches may be controlled by the shaft Q if required. Instead of the pin coupling the shaft Q may be driven by a ratchet through reduction gearing. A second embodiment is described in which the parts are assembled somewhat differently.
