Title: Improvements in or relating to car couplers
IPC: B61G3/06
Filed: 1931-07-26
Abstract: 354,163. Automatic couplings for railway vehicles. NATIONAL MALLEABLE & STEEL CASTINGS CO., 10600, Quincy Avenue, Cleveland, Ohio, U.S.A.- (Assignees of Bazeley, A. J. ; 9718, Logan Court, Cleveland, Ohio, U.S.A.) July 26, 1930, No. 11066/31. Convention date, July 26. [Class 103 (v).] In an automatic knuckle coupling for railway vehicles of the kind in which the knuckle B is opened by a pivoted knuckle thrower E actuated by the lock D, the lock, when in its lowermost or locking position, Fig. 1, is adapted to be supported in part upon surfaces 20a, 20b of the tail 20, Fig. 4, of the knuckle by means of an upper laterally projecting lug 21 and a lower shoulder 21a disposed respectively above and below the locking face 41. In addition, the lock is supported at its rear upon the knuckle-thrower E as shown, the latter point of support being to the rear of the centre of gravity of the lock, while the first-mentioned points of support are forward thereof, this arrangement permitting the depending leg 3 of the lock to be retained out of contact with the walls of the coupler head A. The co-operating surfaces 21a, 20b slope rearwardly and thus prevent the forward upper corner of the lock from jamming against the forward wall of the cavity in which the lock operates.

Abstract: 129,424. Baumann, K., and British Westinghouse Electric & Manufacturing Co. July 8, 1918. Toothed gearing. - For alining toothed gearing and for distributing the tooth pressure, bearings for the shafts of the toothed wheels are cushioned and adjusted by films of oil or other liquid maintained between the bearing and its supports by a continuous flow of liquid between the parts. Clearance spaces 16, 17, Fig. 1, below and above a bearing have inlets 18, 19 and outlets 22, 23, and oil is forced through the spaces by a pump or two separate pumps which are provided with throttle or relief valves, so that by varying the oil pressure the bearing may be adjusted vertically.

Title: Master cylinders
IPC: B60T11/224
Filed: 1972-03-14
Abstract: 1345452 Master cylinders FIAT SpA and PS BALDWIN 14 March 1972 [27 March 1971] 11857/72 Heading F2F In a master cylinder having a main spring biased piston 5 on auxiliary piston 8, between the piston 5 and a pedal-operated push-rod 2, and a precompressed spring 15 between the pistons, the chamber 4 between the two pistons communicates with an hydraulic reservoir through two valves, one valve permitting flow of fluid to the chamber but preventing reverse flow, being controlled exclusively by fluid flow, and the other valve being closed when a predetermined movement of the auxiliary piston relative to the main piston occurs. The first valve comprises a sealing ring 25 having an arcuate periphery and seated in a recess in a washer 23 with axial and radial play. Fluid flows from the reservoir via a channel 5a in the piston 5, passages 22, 21, and a space between the washer 23 and the piston 5, defined by radial ribs or grooves on the washer, forces the ring 25 away from contact with the washer, to allow the flow to continue past a second washer 16 to the chamber 4. Reverse fluid flow causes the ring 25 to abut the washer 23 to block the flow. The second valve comprises an 0-ring in a recess in the washer 23 and at least partially covering at least one passage 30 in a rod fixed to the piston 8 and communicating with the passages 21, 22, 5a, when the pistons are at rest. When the auxiliary piston 8 moves towards the piston 5 a predetermined amount, the passage(s) 30 are covered by the O-ring and fluid flow is blocked. Therefore the spring 15, apart from prestressing, need not be very rigid since the fluid in the chamber 4 provides the force on the piston 5.

Abstract: 197,337. Carpenter, C. U. May 3, 1922. [Convention date]. Type-lever machines.-A compact portable machine comprises key-levers pivoted at the top of the framework and having depending arms connected to type-levers pivoted in a segment arranged at the bottom of the framework. Typelevers 12 are pivoted on an arcuate segment 14 secured to a plate 19 which is secured to the sides of the framework 11. The pivot-wire 21 for the type-levers lies in slots 22 in the segment, and is provided at the ends with screws 23. The heads 27 of the type-levers rest on a horizontal arcuate shelf 28 of greater radius than the segment, the tvpes being accessible for cleaning &c. The types preferably strike the platen at a point above the horizontal line through the axis. The type-levers are connected by links 68 to the key-levers 56 - - 59, and are curved to provide space for a pivot-rod 62 for the key-levers. The key-levers 58, 59 of the two upper banks of keys. 53, 54 are pivoted on the rod 62 and have depending arms 66 connected to the links 68, and the key-levers 56, 57 of the two lower banks of keys 51, 52 are formed with depending arms connected to the links 68, and arms 95 pivoted on the rod 62, or, preferably, on a rod 81. The arms of the key-levers are graded in length to render uniform the touch of the keys. The type-heads 27 are normally adjacent to the pivots 62, 81. Carriage-shift mechanism.-Shift-key levers are connected by links 45, arranged at the sides of the segment 14, to bell-cranks 41 supporting the paper carriage 37.

Abstract: 563,041. Coin-freed meters. LANDIS & GYR SOC. ANON. Aug. 26,1942, No. 11994. Convention date, Sept. 8, 1941. Addition to 550,395. [Class 27] In a modification of the coin freed mechanism described in the parent Specification, a coin pocket 41 is provided normally spring-held projecting out of the casing, in which is a slide 3 held forward in the pocket by a spring 3a. The coin is inserted in the pocket between the partial end wall thereof and the slide 3, the pocket having side openings 43 for inspection, whether a coin is in or not, and also for co-operation of a known coin feeler in the interior of the drum. The slide 3 has recesses 9, 10, 10a for co-operation with a projection 5 in the radially moving slide 6 with the pins 7, 8, 8a which correspondingly actuate the quantity setting pinion 11 for the appropriate one of the three proper kinds of coin inserted. The slide also has the pin 36 sliding on the guiding stop 38 for the normal position of the drum A set of fine ratchet teeth 42 on the slide 3 engages the projection 5 if an improper coin is inserted, to hold the slide 6 from quantity setting and to let the coin fall from the pocket during the ineffective turn of the drum. The slide has an aperture 40 to clear the energy storing pinion 17 which is engaged by racks 45 in the apertures 44 in the sides of the pocket 41. The pocket has a recess 46 larger than those on the slide 3 to clear the pin 5, the difference in size allowing the pocket to free the coin and drop it into the receptacle 39 while the drum turns. A roller 47 is provided to engage the end of the pocket after the pin 36 leaves the stop guide 38. The interior of the drum casing is enlarged to allow clearance to the pocket after about 30 degrees turn to facilitate the release of the coin.

Title: Braking system, more particularly for motor vehicles
IPC: B60T11/10
Filed: 1956-04-19
Abstract: 800,217. Servo-brakes. ECKARDT, K., and ECKARDT, J. April 19, 1956, No. 12001/56. Class 103 (1). In a braking system for vehicles, a single auxiliary brake on one of the vehicle wheels is adapted for sole actuation by the vehicle brake actuating member such that, upon actuation, it rotates relatively to its respective wheel axle to cause actuation of the main brakes situated one on each wheel of the vehicle. In the embodiment illustrated, actuation of the auxiliary brake 4, by depression of brake pedal 1 acting upon a master cylinder 2 and wheel brake cylinder 3 causes the brake shoe carrier of the auxiliary brake being driven by the brake drum 8 when the shoes 5 and 6 are applied. The movement of the brake shoe carrier 7 acts through levers 9, 10 and 11 to actuate compensating balance beam 13 and the master cylinders 14, 15 for actuating the main brakes 16, 17, 18, 19. The auxiliary brake 4 engages the same wheel of the vehicle (rear wheel) and the main brake 16. The opposing spring force 20 for the main brake 16 is weaker than the spring force on main brakes 17, 18, 19, thus permitting the main brake 16 to lock its wheel first before the other wheels are locked by the other main brakes. The opposing spring force 21 may be adjusted by screw-threaded connections 22-25 to vary the force required to apply the main brakes. The braking force in the system may be transmitted mechanically instead of hydraulically as in the present case.
