[Class 38 (v)] The quick release in each phase of a multipole circuit-breaker, as described generally in Specifications 588,724, 588,738, 588,749 and 588,750, is applied to the moving contacts of a threephase motor protection switch, which is closed and held closed by an electromagnet 2 mounted on an insulating contact carrier 1. The moving contacts 8 are resiliently mounted on blade springs 12, which are latched forward on the carrier by pawls 10 engaging blade-spring latches 14. When the latch in any phase is tripped by the arm 17 of an overload-release magnet (not shown) the contact 8 is carried back from the fixed contact 6 by the blade spring 12, and the pin 10a strikes the common release-bar 22, thereby rocking the shaft 4 and bell-crank lever 35 so that a pin 34 thereon opens the contact 33 of an auxiliary switch in the coil circuit of the magnet 3. The trip is reset by depressing the knob 28 so that the slide 26 first carries back the blade spring 29, releasing the arm 38 so that the hook 39 is carried up by the blade 40 to engage a pin 42 on the carrier 1 and latch it in the open position. At the same time the contact 32 of the auxiliary switch is opened and the end of the recess 25 in the slide 26 engages the arm 24 to rock the shaft 4 so that the release-bar 22 bearing on the pin 10a forces the pawl 10 on to the catch 14. On releasing the button, the spring 29 carries the slide back to close the auxiliary switch, and at the same time bears on the arm 38 to unlatch the contact carrier. A bimetal strip 45 may be arranged to trip a catch 47 so that the spring-biassed lever 48 engages the extended contact arm 49 to open the auxiliary switch on overheating of the motor.

Abstract: 411,493. Couplings and draw-gear for railway vehicles. SOKOLOWSKI, W., Huta. B. Hantke, Czestochowa, Poland. Dec. 8, 1932, No. 34874. [Class 103 (v).] In an automatic coupling for railway vehicles of the 1 ind in which a transversely sliding bolt 4, Fig. 5, in each head is adapted to be moved by a guide surface 2<a> on the other head into engagement with a wedge-shaped recess 3<a> on the latter, the bolts 4 are locked in coupling position by means of longitudinally moving slides 5 actuated by springs 7 and adapted to enter slots o in the bolts 4, the slides being operated for release by one or other of two double-nosed cams 6 coacting with slots 5a and lugs 5b on the slides. The rear ends 5d of the slides are thickened to perform a double function, that is, in the coupled position, to engage with grooves 4<a> in the bolts 4 to prevent displacement thereof, and, in the uncoupled position, to engage the rear edges of the bolts and so maintain the slides 5 in a retracted position with the springs 7 compressed. Actuation of the cams 6 is effected by a chain 21, Fig. 2, connected to a lever 8 on a cam shaft 9, the lever being fitted with a pivoted tappet 10 which is adapted to drop behind a projection 2b on the opposed coupler-head and so maintain the lever 8 and cams 6 in the unlocked position when once moved there. Draw-gear ; couplings, convertible. In the transition period, when couplings of the kind described secured to the vehicle frame are being substituted for the ordinary screw couplings, the coupling may be temporarily supported on the draw-hook as shown in Figs. 1 and 2 by means of a pair of parallel pivoted links 19 having lugs 19<a> that are engaged by a bow 18 pivoted at 17 on bent links 16 mounted on the draw-hook. Springs 12 bearing against a fixed support 14 normally serve to swing the links 16 downwardly so that a cross-piece 16<a> rests on the shank of the draw-hook, with the links 19 maintained at a small inclination to the horizontal. At their outer ends the links 19 have additional projections 19b abutting against the coupler-head 1 whereby the latter is permitted to pivot upwardly to give the flexibility necessary to effect a coupling with the opposed coupler-head, the links 19 being allowed a downward movement against the effort of the springs 12. By raising the bow 18, the links 19 are released and with the couplerhead drop to a vertical position when the draw-hook is to receive the chain of the non- automatic coupling.
