Title: Improvements in electrically-controlled brakes for rotating parts
IPC: H02K7/102
Filed: 1938-12-21
Abstract: 523,003. Brakes. WADKIN, Ltd., SIMS, W. L., and MOORLEY, G. W. F. Dec. 21, 1938, No. 37162. [Class 103 (i)] In a brake mechanism of the kind in which a self-energizing brake is applied by energizing or de-energizing an electro-magnet when the drive to the part to be braked is interrupted, one member of the magnet is connected to one of the brake elements and moves with that element towards the rotating brake element when the magnet is energized or de-energized as the case may be, and the frictional drag in the first mentioned brake element causes a part rotation thereof which effects an increase in the braking pressure. The disc brake Fig. 2, 3 comprises a brake disc 11 secured to the shaft 10 of the machine adapted to be engaged by a friction lever 12 on a disc 13 rotatably mounted on a member 15 to which is secured the armature 14 of a magnet 27. The parts 14, 15 are connected by a pin 20 to a forked arm 17 pivoted at 18 on which abuts a spring 25 tending to apply the disc 12, 13 to the disc 11 but prevented from doing so when the magnet 27 is energized. Upon de-energization of the magnet a frictional torque on the disc 12, 13 consequent upon its initial engagement with disc 11 causes projections 21 to ride up fixed cam surfaces 22 to increase the pressure applied to the discs. An internally expanding brake may be employed instead and comprises a pair of brake supports 34 radially slidable and adapted to pivot on a pair of fixed pins 38. A brake shoe 32 is mounted with freedom for circumferential movement between a pair of projections on each support and bears also on parts 35 of the support. Springs 43, 44 extending between the shoes and the supports hold them normally in a centralized position on the supports. A magnet 42 and its armature 41 are secured respectively to the two supports 34 and when energized, draw the supports towards each other to release the brake against the action of a spring 45 attached to one support and acting on the other through a bell-crank 46 pivoted at 47 on the magnet 42 and ' engaging the armature 41. When the magnet is de-energized, the supports 34 with the shoes are moved outwardly on the pins 38 by the spring 45 and the frictional drag on the shoes by the rotating drum effects engagement of cams 36 on the shoes with the abutments 35 causing the supports 34 to re-engage the pins 38 and increasing the pressure between the shoes and the drum. When the machine &c. is driven by an electric motor, the magnet may be arranged to be energized when the motor is energized, as by connecting in parallel. The brake may be arranged to be engaged by energizing the magnet and it is stated in the Provisional Specification that the magnet may be operated by a clutch lever or belt-shifter. An electrically driven wood-working machine having a highspeed rotating tool may be provided with this brake mechanism.

Abstract: 1276060 Time switches LANDIS & GYR AG 3 Aug 1970 [8 Aug 1969] 37335/70 Heading H1N In a time switch having two time discs 1, 18 rotating at different speeds and co-operating with respective contact actuating members 4, 5, and 15, 16 mounted on a common shaft 7, the contact actuating members 4, 5 co-operating with the faster (day) disc 1 are displaceable along the shaft 7 by the slower (week) disc 18 whereby the contact operations performed by the members 4, 5 under the control of the faster disc 1 may be prevented. Members 4, 5 are starwheels carried on a sleeve 6 rotatable with shaft 7 by a pin 8, axial movement of sleeve 6 being permitted by an axial slot therein. Tappets 2, 3, adjustable on disc 1, co-operate with star-wheels 4, 5 to actuate contact sets (not shown) through cams (not shown) at the lower end of shaft 7. Contact actuating members 15, 16 are also starwheels which are actuated by adjustable tappets 17 of week disc 18. Star-wheels 15, 16 are formed on a connecting member 12 rotatable on shaft 7. Connecting member 12 co-operates by way of recesses in one end with complementary saw teeth on the end of a connecting member 11 which is prevented from rotating in the clockwise direction by an abutment 20 and is normally restrained from anticlockwise movement with connecting member 12 by a spring 21. When the teeth of member 11 are aligned with the recesses of member 12, due to rotation of member 12 by week disc 18 a spring 9 moves the member 11, sleeve 6, and star-wheels 4, 5 down the shaft 7 so that the star-wheels 4, 5 no longer co-operate with tappets 2, 3. Thus switching operations controlled by day disc 1 are prevented until the member 12 is advanced again by week disc 18. Should either star-wheel 4, 5 be situated immediately below a tappet 3 during its return movement, the spring 21 yields, permitting members 11 and 12 to rotate together until the star-wheels 4, 5 can move up without interruption.

Abstract: 371,424. Electric signalling systems. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A. -(Assignees of Allegemeine Elektricitats- Ges. ; 2, Friedrich Karl-Ufer, Berlin.) Dec. 17, 1930, No. 38098. Convention date, Dec. 18, 1929. [Class 40 (i).] In electrical means for indicating measurements at a remote point, in which a rotating member, the speed of which is proportional to the measurement, connects at each revolution or part of a revolution the primary of a transformer to a direct-current source, the receiving instrument is a direct-current instrument which is supplied with the secondary impulses of the transformer through a rectifying arrangement. In the construction shown in Fig. 1. the current impulses in one direction are suppressed by a rectifier. In the modification shown in Fig. 2, two rectifiers are employed to supply current to the indicating instrument from impulses in both directions. In the arrangement shown in Fig. 3, a relay a is provided which is slow to energize, so that its contact aa is closed after the closing impulse through the secondary of the transformer has ended. Only the impulse caused by the opening of the primary circuit is supplied to the indicating instrument. In a modification the closing impulse only is supplied. In the construction shown in Fig. 5, the impulses transmitted energize the relay R2 which at contacts r2<SP>1>, r2<SP>2> change the connections from the secondary of the transformer to the indicating instrument, and at contact r2<SP>3> completes a circuit for relay R1. The contact r1 therefore closes a circuit through the primary of the transformer so that the secondary closing current impulse flows to the indicating instrument through lines r. When the relay R2 is de-energized the contacts r2<SP>1>, r2<SP>2> are changed to the position shown and relay R1 is de-energized. The secondary opening current impulse passes through lines l and through the indicating instrument in the same direction as the closing current impulse. Specification 342,681 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) comprises also an arrangement for use in transmission over great distances, in which the receiving arrangement is actuated by a receiving relay controlled through a relay at the transmitting point. This subjectmatter does not appear in the Specification as accepted.
