Abstract: 471,083. Railway &c. vehicle bogies. SOC. D'INVENTIONS AERONAUTIQUES ET MECANIQUES S.I.A.M. Aug. 5, 1936, No. 21600. Convention date, Nov. 18, 1935. [Classes 103 (vi) and 108 (ii)] The body of a railway or other vehicle is resiliently supported upon a bogie by means of a single supporting member such as a rubber cushion, oleo-pneumatic spring, &c., which constitutes the sole means for preventing wheel displacements from being transmitted to the body. In the railway vehicle bogie construction shown in Figs. 3 and 7, the axles E are directly mounted in a frame of H-shape comprising a plain side frame 4 pivoted at 6 to a second frame member in which transverse limbs 5 are formed integrally with a side frame 3. Between the limbs 5 a channelled support or plank 11 is suspended by swing links 9, such plank supporting by means of a single central rubber block 13 a bolster 12 on which the vehicle body is pivoted at 14. Side sway of the bolster is resisted by means of longitudinal arms 20 connecting the bolster to a torsion rod 17. The Specification as open to inspection under Sect. 91 also describes a modification in which anti-rolling springs are inserted between the plank 11 and bolster 12 on each side of the resilient support 13. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to snap action mechanisms
IPC: H01H15/18
Filed: 1955-07-30
Abstract: 805,662. Snap-action switches. BROOKHIRST SWITCHGEAR Ltd., and BUTTERWORTH, E. M. July 30, 1956 [July 30, 1955]; No. 22098/55. Class 38 (5). A snap-action switch has a driven member with two retaining pawls arranged so that one of two spring connected trip catches releases a pawl after the spring means has been tensioned so as to allow the second trip catch to move the driven member with a snap-action. The driven member 14 and trip catches 22, 23 are slotted and slidable on rivets 12, 13 between two plates 10, 11. The trip catches 22, 23 are pulled towards each other by springs 27 and held apart by a projection 17 on the driven member 14, which projection passes through a slot in the plate 11 to operate the switch. When the catch 23 is moved to the right the springs 27 are tensioned until a flange 28 of the catch 23 engages the pawl 19 so as to disengage it from the rivet 13 and allow the catch 22 to move the driven member 14 to the right, whereupon the pawl 18 engages the rivet 12. The members 10, 14 are slotted to allow an operating member 30 to pass through and engage the flanges 28 of the catches 22, 23. The slots have openings 36a, 37a which are only in line in the " OFF " position so that the bent end 35 of the member 30 can only be disengaged in this position, thus allowing withdrawal of a lid slidably supporting a plate 33 carrying the member 30. The plate 33 has ratchet teeth 34 engageable by a pinion on the operating-handle spindle. The switch can still be operated, without snap-action, if the springs 27 are broken.

Pumps P 1 , P 2  and P 12  maintain the circulation and non-return valves N 1 , N 2  prevent shortcircuiting. A header tank T is connected through a pipe 11 to the lowest part of the system and keeps the system full of coolant. The tank T is vented to atmosphere at V and the radiator R 1 , R 2  are vented to the tank T by pipes 9 and 10. In a further form, Fig. 2 (not shown, auxiliary engines are provided for supercharging the main engines and for driving the pumps. These auxiliary engines and also any necessary oil coolers are connected into the third circuit of the system. In this form two header tanks are provided, the vent pipe of each tank being under the control of a float valve which operates to prevent, except at excessive pressure, liquid flowing from one tank to another due to the pressure difference which arise from variations in the speeds of the respective pumps associated with each group of engines.
