Abstract: 549,878. Variable-speed gearing. RUAU, F. F., and MOLINS MACHINE CO., Ltd. May 8, 1941, No. 5999. [Class 80 (ii)] Variable speed is transmitted automatically to a driven member, e.g. a conveyor chain 21 of a cigarette collecting machine, by ratchet gearing, the stroke of the ratchet mechanism being varied automatically in accordance with the rate at which the material may be handled by the machine. As shown, the sprocket wheel 50 of the chain 21 is fixed to a shaft 54 which is rotated by ratchet rollers 66, Fig. 4, upon oscillation of a member 68. The latter is moved by a bar 71 secured to it at 70 and having a pin and slot connection 73, 72, with a two armed lever 82 pivoted to a fixed frame at 75. The lever 82 is oscillated by a crank and connecting rod mechanism 79, 80, driven through reduction gearing in a casing 77. The bar 71 is moved by the lever 82 to the left, Fig. 2, to drive the sprocket 50 and is returned by' spring means. An abutment 96 having a toothed inclined face 97 is fixed to the end of the bar 71 and the return movement of the bar 71 under spring action is limited by the engagement of the abutment 96 with a knife-edged rod 98. The latter is pivoted on a fixed member at 99 and has an arm 100 adjustably secured to one end of a rod 41 the other end of which is pivoted to a lever 39. Movement of the lever 39 thus varies the position of engagement of the members 96, 98 to vary the stroke of the ratchet gear and thus the speed of the conveyer chain 21. The chain 21 moves container R', R<SP>3</SP> to receive cigarettes delivered by a band 2. The lever 39 is moved by a plate 37 bearing on a flexible member 17 which moves according to the quantity of cigarettes accumulated adjacent the supply paddle 9.

Title: Engine starting apparatus
IPC: F02N15/02
Filed: 1926-03-08
Abstract: 261,696. Eclipse Machine Co. Nov. 21. 1925, [Convention date]. Driving arrangements.-An engine starter comprises a driving member 14 adapted to engage and crank an engine member 15, an inertia device such as a flywheel 60 adapted to drive the member 14, manual driving means operatively connected with the inertia device, and a dynamo 150 which can be used as a motor to drive the inertia device or can be driven, with the inertia device, as a generator for wireless transmission or other purposes, by the manual driving means. In one form, Fig. 1, the flywheel 60 is set in rotation before the members 14, 15 are brought into engagement, and a shell 159 in threaded engagement with the shaft 158 of the dynamo comes automatically into engagement with the web 61 of the flywheel when the dynamo is driven as a motor. The transmission between the flywheel and the member 14 includes bevel gears 63<a>, 45, spur gearing 41, 41, 39, and planet pinions 31 meshing with the pinion 39 and with a stationary internal gear 29. Carrier plates 32, 33 for the planet pinions are splined to a barrel 4 rotatable in a bush 3 and connected by a multiplate clutch 6 to a shell 5. Internal threads 12 in the shell 5 engage a screw shaft 13 to which the driving member 14 is connected by splines, a spring 22 normally holding the member 14 against the head of a manual operating-rod 23 extending centrally through the gearing. The manual means for driving the member 14 or the dynamo comprises a shaft 52 engaged bv a starting handle and connected by bevel gears 57, 49 to a shaft 24 having pins 88 in engagement with the hub of the planet carrier 33. Rotation of the starting handle is thus transmitted to the flywheel 60 through the planetary gearing 31, 33 and the gearing 41, 43, 45, 63<a>. To drive the dynamo 150 as a generator, a shell 163 sliding on splines 169 on the dynamo shaft has pins 167 for engagement with holes in the web 61 of the flywheel and is moved into engagement by means of a rod 166 and yoke 165. A spring-pressed locking-rod 170 holds the rod 166 and shell 163 in the engaged or disengaged position. In a modification, the hand-controlled shell. 163 is omitted and the dynamo connections are reversed when it is to be driven as a generator; the shaft 52 is engaged and driven backwards by a starting handle having a longitudinal slot for engagement with the pin 53. The flywheel 60 is thus driven backwards and the shell 159 has sufficient frictional contact with the flywheel to clamp it and establish driving connection with the dynamo. In another form, in which a shell such as 163 is employed, the can be disconnected from its shaft, spring-controlled plungers in the hub of the flywheel being held or released by the tapering end of a manually controlled rod sliding axially in the shaft.

Abstract: 398,418. Audible-signalling apparatus. FLORISSON, C. L., 11, Rue de Cronstadt, Becon-les-Bruyeres, and SOC. DE CONDENSATION ET D'APPLICATIONS MECANIQUES, 42, Rue de Clichy, Paris, both in France. March 2, 1933, No. 6438. Convention date, May 20, 1932. [Class 118 (ii).] In pressure waves or vibration generators for submarine signalling, echo-sounding or like purposes of'the type employing a piezo-electric crystal in an oscillatory circuit, the oscillatory circuit is shock-excited by the charging or discharge current of a condenser or the inductive " kick " generated upon opening the circuit of an induction coil. As shown in Fig. 1, a condenser 4 is charged from a source of supply 3 when the switch 6 engages contact 7. When the switch is moved into contact with contact 8 the condenser discharges through a coil 5 coupled to the coil 2 in circuit with the crystal 1, and the steep wave front of the discharge current shock excites the circuit 1, 2 to produce a damped oscillatory wave train. A resistance 9 is adjusted so as to render the shock circuit aperiodic or, if oscillatory, in a highly damped condition. In the modified arrangement shown dotted, shock excitation occurs by virtue of the steep wave front of the charging current of the condenser. In further modifications shock excitation may be produced by both charging and discharge currents and the coil 5 may. be dispensed with by utilizing a tapping on the coil 2. In the modification shown in Fig. 5, shock excitation is produced by the e.m.f. induced in the coil 10 when the switch 6 is opened. The switch 6 may be replaced by apparatus, e.g. a rotary or vibratory switch or a " relaxation " oscillating device and a morse key, adapted to interrupt the circuit at a desired frequency.
