Title: Improvements in valve mechanism for compressed air brakes
IPC: B60T15/30
Filed: 1926-11-18
Abstract: 279,264. Drolshammer, I. Nov. 18, 1926. Fluid-pressure.-A brake accelator and control valve for compressed air brakes comprises a piston 1 subject on its upper side to train pipe pressure and on its lower side to the pressure in a control chamber A fed through a passage 37. On reduction of train pipe pressure to apply the brakes the piston 1 moves and by means of a cup leather 115 held between two parts of the piston rod 2, first closes the exhaust port 19, then opens the inlet port 17 of a transfer chamber 41 to which compressed air escapes from above the piston and the train pipe the consequent further movement closes the exhaust port 20 and opens an inlet port 18 of a second transfer chamber 42, which causes a further escape of air under pressure and rise of the piston rod which through a spring 11 raises a piston 12 to close the brake cylinder exhaust valve 16 and open the brake cylinder inlet valve 5 to connect the auxiliary reservoir B to the brake cylinder C. When the reduction of train pipe pressure is stopped the brake cylinder pressure acting on the piston 12 compresses the spring 11 and allows the valve 5 to close maintaining a definite pressure in the brake .cylinder at each train pipe pressure reduction. When the train pipe pressure has been reduced for maximum brake application a port 34 is opened connecting the train pipe to a further transfer chamber 120 which in the case of express and passenger trains may be connected to the brake cylinder duct 22 through a non-return valve 75 to allow air to pass from the train pipe into the brake cylinder. On increase of train pipe pressure to release the brakes the piston 1 moves down to open the transfer chambers in turn to the exhaust port 54 through grooves 23 in the piston rod and the brake cylinder is exhausted through the port 54 by the valve 16, which is reclosed by piston 12 acted on by the spring 11 at each stage of the release. The charging of the auxiliary reservoir through a duct 24 causes air to pass through a cock 95 and passage 28 to charge the chambers above and below the piston 1.

Title: Improved method and apparatus for applying socket-nipple end fittings to hoses
IPC: F16L33/207
Filed: 1950-11-30
Abstract: 680,080. Jointing by forging. AEROQUIP CORPORATION. Nov. 30, 1950 [Dec. 10, 1949], No. 29378/50. Class 83 (iv). [Also in Group XXVIII] A method of applying a socket-nipple fitting to a hose end portion comprises holding the hose end within an annular cavity formed between the socket and nipple with the socket and nipple correctly positioned for final securing upon the hose end and subjecting the socket to fluid pressure within a confined space abounding the socket to deform it on to the hose, partially collapsing the said annular cavity to compress the hose end between the inner nipple and the deformed outer socket. A hose end portion comprises inner and outer layers 10 and 12 respectively and an intermediate reinforcing layer 14 bored to contact the interior surface of a socket 16. An inner nipple 18 screws into the socket and forms an annular cavity with the socket into which the hose end is introduced. Apparatus for affixing the hose end within the cavity comprises a cylindrical body 22 into which the hose end assembly is introduced. Sealing rings 24 in the body engage the enlarged end portions 34 of the socket so forming a fluidtight annular space 38 abounding the reduced socket portion. An end flange 40 on the socket locates the assembly in the body. A filler ring 11 is inserted between the socket and the intermediate layer 14 of the hose and an end closure cap 42 is screwed on to the nipple 18. The body is closed by a disc 44 having a central opening 48 which can be connected to a compressed air supply for ejecting the finally-assembled end fitting from the body. Fluid pressure is introduced through a port 26 into the cavity 38 and the socket is deformed on to the hose as shown in Fig. 4. The pressure may also be produced by gas or by means of an explosive cartridge. In an embodiment an elastic sleeve 50 having enlarged end portions 70 applies the fluid pressure to the socket 52 and seals the ends of the annular space 54. The hose end assembly together with the sleeve 50 is inserted into a cylindrical body 66 and retained in position by means of a plug 68. Fluid pressure is introduced into the space 54 through a port (not shown) to collapse the sleeve on to the socket and deform the socket on to the hose. The fluid is drained through a port 74.

Filed: 1933-10-24
Abstract: 425,182. Speedometers. HEMPHILL CO., Central Falls, and LAWSON, R. H., 55, Cooke Street, Pawtucket, both in Rhode Island, U.S.A. Oct. 24, 1933, No. 29482. Convention date, Oct. 26, 1932. [Class 106 (iii)] [See also Group VIII] Relates to means for indicating whether two or more threads or yarns in a textile machine, e.g. the yarns supplied to the several feeds of a multi-feeder knitting-machine, are running at equal speeds or not, and for manually or automatically equalizing the speed of threads or yarns running at unequal speeds. In one form, the indicating device comprises rotatably mounted discs 16, 17, some of which have apertures 26 therein, and the others have corresponding markings 25 or apertures. The discs are grooved peripherally to receive the threads so as to be driven thereby. Inequality in the speeds of threads is indicated by an apparent movement of the markings 25, seen through the apertures 26. An electricallydriven rotary member, the speed of which may be varied by a rheostat and may be shown by a speedometer, may be used in conjunction with the discs 16, 17. Further, the apertures 26 and markings 25 may be replaced by peripheral or other contacts, so disposed that with the discs rotating at equal speeds the contacts on adjacent discs do not touch, but that, upon unequal speed, eventually engage to close an electric circuit. Discs 16, 17 each having apertures 26 may be used together with selenium or photo-electric cells to operate a bell or a visual indicator by means of a light. In another form, Figs. 10, 11, the threads pass over and drive grooved discs 43, which by means of worm gearing 47 drive discs 48. Springs 57 are mounted upon the discs 48 so as to be carried thereby and have ends projecting radially of the discs to serve, with stops 55, to indicate the amount of movement of the discs 43, 48. By stopping the machine, the relative speed of any of the threads can be readily determined. Specification 425,197 is referred to.
