Title: Knitting machine
IPC: D04B9/22
Filed: 1950-03-13
Abstract: 704,852. Change-speed control ; friction clutches. SIRMAY, J., and ZERUNEITH, R. E, Class 80 (2) [Also in Group VIII] The main drive of a knitting-machine is derived from a motor having two pulleys of different diameter connected by belts to two adjacent pulley wheels 100, 101 of equal dimensions freely and independently mounted on, the main drive shaft 102 of the machine. The drive is obtained by frictionally coupling one or the other of the pulley wheels to the shaft 102 thereby providing a high or low-speed drive, The pulley wheel 100 has an axially extending flange 103 to the end of which is rigidly secured a member 112. The pulley wheel 101 also has a flange 111 extending along and around the flange 103 but separated therefrom by antifriction bearings. Split rings 114, 115 are positioned on the flange 111 and member 112 and have diametrically opposed lugs 123, 122. A lever 126 pivoted to a housing 128 keyed to the shaft 102 has one end in engagement with a member 131 slidable on the shaft 102 and having a conical portion 132. The opposite end of the lever 126 is chamfered and engages studs 124 adjustable in the lugs 123. The lugs 122 are engaged by a shaft 154 having flats 155, 156 at right angles to each other and in alignment with the lugs 122 on the rings 114, 115 respectively. The shaft 154 is mounted in the housing 128 and has projections 159, 160 at one end adapted to engage the end of a pivoted lever 161 controlled so as to be either in alignment with the projections 159 or 160. As the housing rotates, dependent on its position, the lever 161 engages' the projections 159 or 160 so that either a flat 155 or 156 is brought into contact with the lug 122 of the ring 114 or 115 respectively. Actuation of the lever 126 by its engagement of the conical portion 132 by the member 134 being moved by a hand controlled lever 135, urges the chamfered edge of the lever 126 into contact with the studs in the lugs 123. One of the flats 155, 156 being adjacent the lugs 123, the actuation of the lever 126 serves only to move the corresponding split ring about the axial portion 111 or member 112. The other split ring having its lug 123 held by the shaft 154. grips the portion 111 or the member 112 and the drive from the corresponding pulley wheel is transmitted through the housing 128 to the shaft 102. The control of the lever 161 is obtained by an extension on the lever 270 actuated by the pattern chain to cause it to engage a micro switch. The drive to the cam shaft 191 from the shaft 102 is through bevel gears 190, 192. Specifications 704,923, [Group VIII], 704,932; 704,933, 704,938 and 704,939, [all in Group VIII], are referred to.

Title: Improvements in or relating to railway train control
IPC: B60T7/12
Filed: 1923-03-06
Abstract: 209,629. National Safety Appliance Co., (Assignees of Folker, H. S.). Feb. 7, 1923, [Convention date]. Addition to 170,814. Fluid-pressure. - Modifications in the brake application valve for the automatic train-stopping mechanism described in the parent Specification include chiefly the substitution of a diaphragm for the piston which actuates the valves for cutting off the air supply to the train-pipe and for venting this pipe. The casing 1 is interposed in the train-pipe the part o of which leads to the driver's valve and the part t to the brakes. A diaphragm 17 secured between the casing 1 and a cap 11 is attached to a valve 6 having a stem 2<a> which also carries a valve 2. The chamber e on one side of the diaphragm 17 is supplied with air at main reservoir pressure through a restricted passage 15b, the chamber d and passages 15<2> in a stem 15. The chamber e is also connected by a passage f to the pilot or control valve described in the parent Specification which is adapted to be opened by means on the track. Normally, the pilot valve being closed, the main reservoir pressure obtaining in the chamber e, opposed to the train-pipe pressure in the chamber v holds the valve 6 seated and the valve 2 open as shown. If the passage f is opened the fall of pressure in the chamber e causes the diaphragm to move to the left unseating the valve 6 and closing the valve 2. The closing of the valve 2 cuts off the train-pipe t from the air supply through the pipe o and vents it to atmosphere through the chamber v and a passage z. When the pilot valve closes, the pressure builds up again in the chamber e and the parts return to the normal position to release the brakes. If however the pressure supply to the chamber e should fail, the valves can be returned by turning a hand wheel 12 which causes a screwed spindle 15<1> to engage the valve and diaphragm member. When the spindle 15 is at its inner position, the passage 15<2> is closed and the air supply to the chamber e thus stopped'. The valve may be used with the modified control or pilot valve described in Specification 209,627. Specification 174,559 also is referred to.

Title: Arrangement for detecting the direction of propagation of a current, particularly applicable to switching in telephone installations
IPC: H04B3/36
Filed: 1928-03-05
Abstract: 286,607. Lange, C. J. A., and Forest, L. J. E. March 5, 1927, [Convention date]. Two-way repeating systems. The direction of energy flow in a telephone line is indicated by inserting a network 10 having an impedance equal to the characteristic impedance of the line and causing the difference in the A.C. voltages at the two sides of the network to produce a. potential difference between points 18, 19 by means of a pair of opposed triode rectifiers 14, 15. A biassed Baudot relay 20 connected to the points 18, 19 may be made through one or more further relays to control an outgoing substation amplifier so that it is connected up only while the subscriber is talking. The relay 20 controlling the amplifier may be controlled by the relay 20, as shown in Fig. 4, so that its operation and release are delayed by a sluggish relay 26. In a modification, Fig. 6, the relay 20 is unbiassed, and when the subscriber at 5 talks, energizes a relay 33 which cuts out the network 10 and closes a circuit through a transformer 34. which induces an impulse in the circuit of a biassed Baudot relay 35 which repeats the impulse over the two sides of the line in parallel to an unbiassed relay 40 at a repeating station and to the relay 20 at the distant substation. Relay 40 energizes relays 42, 43 to connect up the amplifier 9 in the proper direction. When the other subscriber talks the converse of these operations takes place. In a modified method of producing the control impulses, the relay 20 itself connects battery to the mid-point of coil 38, the circuit being broken by a sluggish relay in series with relay 20. The control impulses, which may also be produced by condenser discharges, may be amplified, and may control several repeaters, mav be made in known manner to travel in the line more quickly than the speech currents to ensure that the inital syllables may not be lost. Specification 207,852 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) states that the mechanical switches may be eplaced by known arrangements of opposed thermionic amplifiers.
