Abstract: 125,139. Anderson, H. V. June 10, 1916. Machine guns.-Relates to automatic guns of the kind described in Specification 16038/15, and consists in special trigger mechanism adapted to fire single shots or continuously. The sear n<1> is actuated by a sliding trigger-rod n<12> and a system of links so constructed that a short pull fires a single shot, and a long pull causes continuous firing. The sear n<1>, Figs. 1 and 2, is pivoted at n<2>, and at its lower end has a notched lever n<17> adapted to be engaged by a pawl n<15> mounted on the pivot of a pair of toggle-links n<7>, n<9>. One end of the toggle is pivoted on the sear pivot n<2>, and the other end to a block n<11> fixed on the trigger rod n<12>. The notched lever n<17> is connected by a link n<20> to a pivoted piece n<5> which, when the breech is open, projects upwards into the path of the breech-block. When the breech is closed, the piece n<5> is pressed down by the breech-block, and the notched lover n<17> is thereby turned into a position to be engaged by the pawl n<15>. For single-shot firing, the pull of the trigger is limited by a stop t<2>, Fig. 1<a>. For continuous firing, the stop t<2> is removed and the trigger is pulled farther back, as shown in thick dotted lines in Fig. 1<a>. The parts then take up the position shown in Fig. 2, and each time the breech is closed, the piece n<5> is depressed, the notched lever n<17> is, by engagement with a heel-piece n<24> on the toggle-link n<9>, turned into the position shown in dotted lines in Fig. 2, and the sear is thereby actuated.

Filed: 1928-05-04
Abstract: 291,051. Bosch Akt.-Ges., R. May 25, 1927, [Convention date]. Regulating delivery by by-passes. - In a fuel pump for internal-combustion engines, the delivery is regulated by a bye-pass port e con. trolled by an inclired edge p on a sleeve k carried by the plunger c. A channel n in the plunger connects the pump chamber to an annular space m surrounding the plunger. The bye - passed fuel enters this chamber and then passes through the port e when the edge p clears it. The delivery is regulated by turning the plunger so that opening of the port e by the edge p occurs sooner or later in the delivery stroke. This arrangement of a chamber between the pump chamber and the port e damps the flow of the fuel in the return pipe and so prevents irregularity in the flow of fuel to the suction port d. In another form, the port e opens into a chamber surrounding the pump barrel and the suction port. Specification 263,772 is referred to.

Title: An uncoupling device for use on standard electricity meters
IPC: G01R11/60
Filed: 1941-10-17
Abstract: 548,817. Supply meters; calibrating meters. LANDIS & GYR SOC. ANON. Oct. 17, 1941, No. 13368. Convention date, Oct. 21, 1940. [Class 37] An uncoupling device for a standard meter for use in calibration is operated by means of two electromagnets which are arranged so as to be alternately connected to a coil mounted on the core of the driving magnet and act on the coupling between the driving and counting mechanism by means of armatures alternately coming into a locking or engaging relation with the coupling mechanism. The pointers 6 of the counting mechanism are connected through gearing 7 to the upper part 8 of the shaft of the driving disc 2. The lower part 9 of this shaft is connected with the upper part 8 through a coupling 10, 11, the member 10 of which is axially movable and normally held in engagement with the member 11 by a spring 13. The armature 15 of an electromagnet 16 is pivoted at 14 and has a projection 17 engaging the upper side of a flange 12 on the member 10. An insulating pin 18 carried by the armature 15 engages the spring part of a switch 19 in series with a second electromagnet 20 having an armature 21 which is pivoted at 22 and has an extension 23 engaging the spring part of a switch 24 in series with the electromagnet 16. One end of each of the electromagnet coils 16, 20 is connected to a tapping on the voltage coil 3 of the meter, a second tapping on which is connected to the movable arm 31 of a change-over switch 28, the contacts 27, 29 of which are connected to the switches 24, 19. In the position shown the switch 19 of the electromagnet 20 is open and the armature 21 is locked by the armature 15 and holds the switch 24 of the electromagnet 16 closed. The circuit of this electromagnet is, however, open as the arm 31 of the switch 28 is on the contact 29. When the change-over switch 28 is actuated by pressing the button 32 the arm 31 engages the contact 27 and closes the circuit of the electromagnet 16 which attracts its armature 15 and releases the member 10 so that the counting mechanism 6 is engaged with the driving system 1, 2. At the same time the pin 18 closes the switch 19 and the armature 15 releases the armature 21, so that the switch 24 is opened and the coil 16 de-energized. The armature 15 is locked in its attracted position by a shoulder on the armature 21. If the button 32 is again depressed the arm 31 engages the contact 29, the electromagnet 20 is energized and releases the armature 15, and the switch 24 closes the circuit of the electromagnet 16. A spring 34 rotates the armature 15 which uncouples the members 10, 11 and opens the switch 19, deenergizing the electromagnet 20. Several tappings may be provided on the voltage coil 3 to allow the use of different voltages. Alternatively a separate coil may be wound on the voltage core for operating the electromagnets 16, 20.

Convention date, May 4, 1933. [Class 139] In a clock wherein the regulating member is electrically maintained, the contacting device comprises a pin 3, secured to a disc 2 rigid with the balance staff 1, and a threearmed contact lever 6, the arm 12 of which coacts with the pin 3, while the arms 13, 14 are yieldingly held by a spring 7, secured to a fixed pin 10 and to a pin 11 on the lever, against fixed pivot pins 8, 9 respectively, the pins alternately acting as fulcrum for the oscillatory movement of the lever. The pin 9 is insulated and the pin 8 conducting, so that during rotation of the balance in the direction of arrow A the circuit is closed when the pin 3 engages arm 12 and rocks the lever about pin 8. During rotation of the balance in the reverse direction the circuit is momentarily closed when pin 3 engages arm 12, but is immediately broken as the lever is rocked about pin 9. Instead of insulating the pin 9, however, the lever may be disposed so that the arm 12 is not normally radial to the axis 1, the impulse thereby being of longer duration during one swing of the balance than during the other. The impulses are imparted to the balance by a magnet 5 acting upon an armature 4 rigid therewith.
