Title: Improvements in Electric Rotary Converters.
IPC: H02K47/02
Filed: 1912-11-20
Granted: 1913-11-20
Abstract: 26,680. British Thomson - Houston Co., and- Whitaker, F. P. Nov. 20. Drawings to Specification. Rotary converters. -Relates to rotary converters of the split-pole type described in Specification 7943/08, in which the field-magnet poles are divided into main poles and auxiliary poles, the latter being wound with regulating-coils for the purpose of shifting the field magnetization with respect to the brushes so as to vary the voltage ratio, and consists in providing the machines with additional commutating-poles which are arranged between the field-magnet poles and are excited by continuous current in series with the armature. The converters are thus enabled to operate with improved commutation on alternating-current circuits of higher frequency, and their armatures may be rotated so as to meet the auxiliary poles before the main poles in their rotation.

Title: Improvements in Variable Speed Gear and Clutch Mechanism for Motor Cycles, Cycle Cars and the like.
Inventor: BOWDEN FRANK
IPC: B62M25/00
Filed: 1913-01-04
Granted: 1914-01-01
Abstract: 273. Bowden, F., [trading as Raleigh Cycle Co.J, and Cohen, I. Jan. 4. Variable speed epicyclic gearing for motor-cycles &c., of the kind comprising two or more epicyclic gear trains capable of giving three or more speeds of which the top speed is the normal, is provided with means whereby one of the gear trains employed for giving forward speeds may be also used to give a reverse speed. For this purpose, when the sun-pinions b<1>, b<2> are in the direct-drive position the second internal wheel e, the carrier h, and the planetwheels a<2> may be moved bodily to the right to clutch the carrier to a stationary member m and the internal wheel to the member g; a reverse drive is then transmitted through the clutch i to the hub. The sun-pinion b<1> is freely mounted on a sleeve or extension b<3> of the second sun-pinion b<2> and for the direct and reverse drives is clutched to the extension by teeth b<4>. In the position shown, the pinion b<1> is clutched to the carrier d and to the extension b<3>, and the internal wheel c is clutched to the carrier d; this gives the direct forward drive. Movement of the sun-pinion b<2> to the left disengages it from the pinion b<1> and locks it to the fixed clutch k<2>, so that a lower speed is obtained. Further movement of the pinion b<2> brings a shoulder b<Î> against the pinion b<1>, which is then moved into engagement with fixed teeth k<3> so that both pinions are held stationary to give the lowest speed. Springs p, o tend to keep the parts in the normal or direct forward-drive position. The members e, h, a<2> may be moved to the right for the reverse drive by a control rod within the axle or by a stud projecting through slots in the hub and carried by an external and laterally-movable sleeve. The gear may be used in a countershaft position, the hub being fitted with one or more pulleys or one or more chain-wheels, or the hub may be stationary, and the driven member g or the hub end l<1>, running on ball bearings between itself and the hub, connected to a belt pulley or the like. Instead of being applied between the gear and the hub, the free-engine clutch i may be disposed between the engine and the gear or between the hub and the vehicle.

Title: Electromagnetic Switching Mechanism for Heavy Current Switches with Automatic Release.
IPC: H01H71/68
Filed: 1913-02-03
Granted: 1913-07-24
Abstract: 2778. Bergmann Elektricitõtswerke Akt.-Ges. Feb. 1, 1912, [Convention date]. Automatic circuit-breakers; electro-magnetic switches. - Relates to distant-control switches for heavy currents, arranged for automatic opening in case of overload. The switch S is closed by a solenoid c controlled by a handswitch k and a throw-over switch h. The switch h being closed, and the switch k being in the position shown, the solenoid e is excited from a circuit g and the main switch after closing is held on by a latch p. The stroke of the solenoid core throws over the switch h and breaks the actuating circuit. The latch may be tripped by a magnet a energized by overloadrelays m or by moving the switch k into position for connecting contacts d, whereupon the switch S opens and cannot again be closed until the auxiliary switch h has been thrown over on the contacts i. This is effected by a magnet b which is excited either by a separate switch f, or by a contact o belonging to the switch k, which in that case has to be put back into the tripping position if it is not there already. In a modification, the magnet a serves solely for opening at will, and separate magnets are provided for tripping the latch in case of overload. A mechanical connexion is made by which in the non-automatic opening of the main switch, the auxiliary switch h is thrown back on the contacts i; in the automatic opening this does not take place, the operator being compelled to put back the switch k to the tripping position before he can re-establish a circuit through the solenoid e. The auxiliary switch h has an additional pair of contacts in circuit with the trip magnet. Indicating-lamps are connected to the contacts of the auxiliary switch and to extra contacts of the main switch.

Abstract: 19,884. Johnson, G. W., [Link-Belt Co.]. Sept. 2. Chain-wheels; tension arrangements.-Relates to mechanical devices for movably connecting a series of three or more juxtaposed chain-wheels to one another and to the shaft upon which they are mounted so as to equalize automatically the tensions in a series of independent chains driving simultaneously and in parallel between such shaft and another shaft. In the arrangement shown in Figs. 1 and 2, a series of chain-wheels 5 are loosely mounted upon the bosses 3 of a series of hub elements 2 secured to a shaft 1, the several wheel and hub elements being interconnected by one or more endless chains 7 each passing outside bearing-parts 8 on the hub elements and between bearing-parts 9, 10 on each wheel element. The arrangement enables a drive in either direction of rotation to be effected between the shaft and the series of chain-wheels and permits relative selfadjustment of the chain-wheels to equalize the tension in a series of independent chains transmitting the drive simultaneously. The bearing- parts 8, 9, 10 are grooved at each side as shown in Fig. 1, the rollers of the chain resting on the raised part between the grooves, and the links of the chain engaging the grooves to retain the chain in position. The bearing-part 8 may be round instead of elongated in section. The parts 9, 10, and the part 8 if round, may be provided with rollers. In a modification adapted to transmit rotation only in one direction, only one of the sets of bearings 9 or 10 on the chain-wheels is emp!oyed, single lengths of chain being passed around the parts in zigzag fashion and connec'ed at the ends to arms upon the shaft or to the end chainwheel elements. Rope or other flexible means may be employed instead of the chains 7. In a modification shown in Fig. 7, the hub and chainwheel elements are interconnected by means of series of levers 17, 18 and links 13. The levers 17 are rotatably but not axially movable in supports 11 and are retained by pins 19, the supports 11 being arranged radially and rotatably mounted in the hub elements.
