Title: Improvements in or relating to fluid pressure brake apparatus for railway vehicles
IPC: H01H63/18
Filed: 1926-01-16
Abstract: 247,535. Hildebrand, W. Feb. 13, 1925, [Convention date]. Fluid-pressure.-In brake apparatus comprising an accelerator valve associated with each triple or equivalent control valve and adapted to vent the train-pipe to a chamber in an application of the brakes so as to prevent the air displaced by the piston of the control valve from being delivered into the train-pipe, means are provided for ensuring the movement of the accelerator valve to operative position before that of the control valve. According to Fig. 1, the apparatus comprises a control valve S and an accelerator valve B connected to the train-pipe at L. The accelerator valve has a short stroke and small frictional resistance so as to be sensitive and comprises a piston q subject on one side to train-pipe pressure and on the other side to that in the auxiliary reservoir H through the pipe e and actuating a pair of slides valves a, b<1>. The valve a is adapted to vent the train-pipe side of the piston q to the chamber U. The control valve S comprises the usual piston k subject to opposing train-pipe and auxiliary reservoir pressures and actuating main and subsidiary slide valves g, s<1> controlling the brake cylinder connection c and normally venting the chamber U to atmosphere by a restricted passage h<1> and a port m. The piston rod of the valve S carries a counter-piston v one face. of which is normally exposed to atmospheric pressure by way of pipe c<1>, valve b<1>, and port i. Upon a slight reduction of train-pipe pressure to effect an application of the brakes, the piston q and valves a, b<1> are immediately moved to close the exhaust port i and to open the pipe l<1>leading to the chamber U, but the movement of the control valve piston k is delayed by reason of the auxiliary reservoir pressure acting on the counterpiston v. The provision of the restricted passage h<1> prevents any considerable escape of air from the chamber U from taking place before closure of the port in by a valve. g. The counter-piston v and valve b<1> may be dispensed with and the smaller resistance to movement of the accelerator valve B compared with that of the control valve S be relied upon to ensure the movement of the one valve before that of the other. In this case, the resistance to movement of the accelerator valve may be further reduced by the substitution of a flap valve for the valve a. According to the Specification as open to inspection under Sect. 91 (3) (a), the invention may be applied to vacuum brakes. This subjectmatter does not appear in the Specification as accepted.
Patent GB-347176-A (GB)
Title: Improvements in and relating to method of and means for putting boxes in order for subsequent operation
IPC: B65G47/14
Filed: 1930-01-14
Abstract: 347,176. Feeding match boxes &c. FAIRWEATHER, H. G. C., 65, Chancery Lane, London.-(Aktiebolaget Siefvert & Fornander; Kalmar, Sweden.) Jan. 14, 1930, No. 1375. [Class 117.] The drawers of match and like boxes are put into predetermined order for subsequent operation, e.g. insertion in the outer shells or for filling, by delivering the drawers to a position in which they rest upon any of their side surfaces with the bottom vertical or substantially so and then mounting them while in this position so as to allow them to turn under the torque due to the weight of the bottoms until the bottoms are directed downwards ; empty or full drawers with the surrounding shells may be similarly treated. As shown the drawers are delivered one at a time from a receptacle 3 by a conveyer 4 and rotating brush 5 to a rotary conical disc 1 by which they are thrown outwards towards a stationary mantle 6 surrounding the disc and spaced from the periphery thereof, the space 7 being such that the drawers can only stand therein on their narrow sides on the flange 8 of the disc. Each box is moved by succeeding boxes from the disc into a discharging channel 13 one wall 14 of which extends adjacent the periphery of the disc while a rotating brush 12 sweeps off surplus drawers or any not in the correct position. From the channel 13 the boxes pass into a receiving channel 15 the bottom of which has a knife edge 17 to cause the drawers to turn over towards one side wall of the channel the walls of which may diverge upwards. The drawers then pass into a channel 18 of more or less circular cross section where the turning of the drawers to a position in which the bottoms are underneath is completed and which leads to a channel 19 of rectangular cross section ; the channel 15 may be dispensed with and the channels may be downwardly inclined or may be given a shaking movement in a vertical plane extending longitudinally through the axes of the channels by a horizontally-disposed lever 21, one end of the lever carrying a roller engaging a cam 20 on the base of the disc 1 and the other end movably engaging a guide 22 on the channels which are mounted in guides. A hammer mounted on a lever operated by abutments on the cam 20 is periodically depressed to rest upon the drawers in the channel 13 a sufficient time to allow the preceding box to turn in the channel 15 or 18. Instead of using turning channels the drawers may be seized by a pair of needle points which engage them at opposite points lying in a line through the centre of the drawer which is then allowed to turn to its desired position by lifting the needles or lowering the supports of the drawer.

Class 82 (2) [Also in Group XXII] A method of making containers from tin plate is characterized in that the two end surfaces of a tin-plate casing forming the body of the container, said end surfaces being untinned over a specified breadth, are first welded together and the welded seam subsequently tinned. Apparatus for carrying out the invention comprises a spiked conveying mechanism for conveying the welded casing 16 along rails 1 from the welding machine. The casing is fed into a cleaning mechanism consisting of two interacting pads 2 which remove the oxide layer from the seam 17. After cleaning a flux is applied to the seam by two superimposed rubber rollers 4 the lower roller lying in a flux bath 3. After fluxing, the seam is preheated to approximately 250‹C. and then conveyed to the tinning apparatus which comprises upper and lower steel rollers 9 and 8 respectively. The upper rollers 9, which may be preheated, are driven by a chain drive 11 from a pulley 10 and are in frictional engagement with the lower rollers which lie in a tin bath 6 heated by a resistance heating device 7. The profiles of the upper and lower rollers are concave and convex respectively, and the 'rollers are spring-loaded by springs 18 and are capable of an oscillatory motion in the direction of feed. The rollers coat both sides of the seam with molten tin. The tin bath 6 has an eternal fitting 5 to ensure smooth conveyance of the casing 16. The tinned seam is then cooled by compressed-air jets (not shown) and passed through spirit-soaked brushes 12 and 13 which polish the seam and remove any remaining traces of flux. The compressed-air jets, the upper brushes of the polishing mechanism, and the upper rollers of the tinning mechanism, including the drive, are swivel mounted to enable them to be raised for cleaning or repair purposes. The seam may be coated on one side only, i.e. inside or outside the casing or the two sides of the seam may be coated with alloys of different compositions.
