Title: Improvements in or relating to a brake control apparatus for railway equipment and the like
IPC: B60T8/32
Filed: 1948-02-03
Abstract: 641,625. Vehicle brakes. AMERICAN BRAKE SHOE CO. Feb. 3, 1948, No. 3133. Convention date, Jan. 9, 1942. [Class 103 (i)] In apparatus for preventing wheel slip of railway vehicles and the like, fitted with devices whereby the speeds of two adjacent axles are compared by electrical means in such a way that if there is sufficient lack of synchronism, relays are operated which actuate valves that exhaust air from the appropriate brake cylinder, the speeds of the axles are registered by means of commutating switch members mounted on axles separate from or forming extensions of the wheel axle and enclosed within the journal box in positions affording ease of inspection. As shown in Figs. 3, 4 and 8, electrical speed detecting units are mounted at the end of each axle A within a casing 15 having an inspection end cover 66. Each unit comprises a fixed outer member 21 having a ring of segments 30 and two slip rings 32 and 35 connected to terminals 34 and 37 respectively, and a core member 22 secured so as to rotate with the axle A, having sets of upper and lower brushes 79 and 78 contacting the segments 30 and further axially spaced brushes 77 and 75 contacting the slip rings 32 and 35. Corresponding segments on the unit S<SP>1</SP> on one axle are connected to corresponding segments on the unit S<SP>2</SP> on the adjacent axle as shown in Fig. 12. Although both sets of brushes 78 and 79 may in practice be fitted to the unit S<SP>1</SP>, only the brushes 79 are shown since only these form part of the operating circuit of Fig. 12 in which the unit S<SP>1</SP> is assumed to be on the axle that is tending to slip. If the axle of unit S<SP>1</SP> rotates at a different rate to the axle of unit S<SP>2</SP>, it is apparent that the brushes 79 of unit S<SP>1</SP> will be electrically connected in turn to the brushes 79 and 78 of unit S<SP>2</SP>, and thus the relays SR<SP>1</SP> and SR2, which are of the slow to release type, will be energized in corresponding sequence. If the wheel of the unit S<SP>1</SP> should slip to such a degree the the two axles become sufficiently out of synchronism to cause the delayed opening periods of the relays SR<SP>1</SP> and SR<SP>2</SP> to overlap so that both the armatures 125 and 126 are closed together, then a further relay SR3 is also energized which causes a valve 100 to be operated to release air from the brake cylinder 92 so as to reduce the degree of braking on the slipping wheel. In Figs. 3 and 4 the core unit 22 of the rotary switch is made to rotate with the axle proper by means of engaging flats 45, special means such as the oil seal 51 being used to prevent lubrication from reaching the slip rings and switch segments. In a modification, the core member has a resiliently coupled inwardly projecting shaft with a splined end boss engaging internal splines in a recess in the end of the axle, this arrangement affording very easy removal of the electrical parts for inspection and cleaning.

Title: Improvements in or relating to coin-freed apparatus or the like
IPC: G07F5/04
Filed: 1928-02-02
Abstract: 314,911. Thrissell Engineering Co., Ltd., (formerly Brecknell, Munro, & Rogers, Ltd.), and Bryan, W. E. Feb. 2, 1928. Coin action, weight and multiple-coin. - In coin-freed apparatus, inserted coins of different denominations, when falling under their own weight, operate a driving arm which moves through a predetermined distance varying according to the denomination of the coin, the driving arm operating a controling disc which controls the number or value of the coins required to actuate the apparatus. Pennies and halfpennies, dropping through shoots 13, 14 respectively actuate a counterweighted driving arm 7 carrying a pawl 9 for driving in clockwise direction a toothed control disc 1, backward rotation of which, under the action of a counterweight 4, is normally prevented. by a pawl 18. A penny causes the arm 7 to move to the position 33 and drive the disc 1 through two teeth, while a halfpenny moves it to position 34 and drives the disc through one tooth. A pin 5 on the disc is initially against a fixed stop 6. After a predetermined value of coins have been inserted, a projection 26 on the disc engages and moves an arm 19 against a spring 25, the arm 19 acting through a link 20 to raise a stop 21 from a delivery drawer 24 or the like. A complete outward and return movement of the drawer actuates a lever 27 which engages a pin 29 on the pawl 18 and raises it to allow the disc 1 to return to its initial position. If a coin over the requisite number be inserted, the pin 5 actuates a lever 31 having a surface 32 which deflects the coin to a return shoot 16 instead of allowing it to pass through a shoot 15 to the money-box. The stop 6 may be adjustably mounted so that the number of coins required to actuate the apparatus may be altered. The movement of the lever 19 may be made to actuate the delivery mechanism instead of freeing it. The disc 1 n.ay be courted to a cam which limits the opening of the delivery mechanism so that the quantity of goods delivered depends on the value of the coins inserted. In a. modification, the disc 1 controls a coin deflector so that the last coin, of a number of predetermined value, is deflected to release the delivery mechanism.
