Title: The control of the parking or emergency brakes of vehicles
IPC: B60T11/04
Filed: 1946-04-11
Abstract: 610,603. Oontrolling motor vehicles. MATON, W. C. April 11, 1946, No. 11124. [Class 79 (v)] [Also in Group XXXIV] A parking or emergency brake on a vehicle is actuated by a lever which is operable independently to apply the brake and has locking means so associated with the main brake and clutch pedals as to be released by actuation of either of said pedals. As shown, a main brake pedal 11 and parking brake pedal 14 are rotatably mounted on the shaft 13 of a clutch pedal 12, the pedals 11 and 14 having extensions 15 and 16 coupled to the brakes. A second shaft 18 carries an arcuate ratchet 19 which is urged by a spring (not shown) into engagement with a prong 25 on the pedal 14, but is depressed by a lug 21 on the pedal 11 when the latter is actuated to apply the main brake. The shaft 18 also carries an arm 27 having a hinged end 28 carrying a roller 29 engaged by a nose 30 on the pedal 12. When the pedal is depressed, the end 28 is deflected to allow the nose to ride over the roller, and on the return movement of the pedal the underside of the nose engages the roller to swing the arm 27 and thus disengage the prong from the ratchet. The emergency brake lever may be arranged adjacent to the main brake pedal so that the two pedals present a substantially flush surface, or it may be remote from the main brake pedal.

Title: Improvements in electro dynamic transmission systems
IPC: H02K51/00
Filed: 1923-04-25
Abstract: 197,322. Sperry Development Co., (Assignees of Sperry, E. A., and Drake, H. C.). May 5, 1922, [Convention date]. Operating clutches.-An electric power transmission system, comprising a dynamo driven by the engine and a motor mounted on the driven -shaft, is provided with a friction clutch which is rendered operative by the relative speeds of the driving and driven shafts. The friction clutch comprises a spiral spring abutting against a stop on the driven shaft at one end and secured by a pin at the other end to a member which normally rotates at the same speed as the driven shaft. The armature 7, Fig. 1, of a generator G is mounted on a sleeve 8 secured to the driving shaft 2. Secured to the sleeve 8 is an annular member 17 containing springs 31, Figs. 1 and 3, which normally hold a member 30 away from an annular member 27, Figs. 1 and 2, secured to the driven shaft 14 through a member 13. A spring 33 abuts against a projection 36<1> on the sleeve 8 and is secured to the member 30. The spring 33 is made progressively lighter, parts being left to keep the spring concentric about the member 17. The member 30 is secured to the member 17 by springs 44, Fig. 3, and pins 45 on the member 30 move in slots 46 in the member 17 to limit the rotation of the member 30 in either direction relative to the member 17. The armature 12 of a motor M is mounted on the member 13 to which is secured a cup-shaped member 50 adapted to_be engaged by the spring 33. The member 27 is provided with a magnet coil 29 which when energized attracts the member 30. The coil 29 is under the control of a differential switch comprising a shaft 60, Figs. 7 and 8,. driven by the engine and a shaft 61 connected to the driving shaft. A pinion carrier 66 is provided with an annular member 67 carrying a slip-ring 76 connected to a contact 74 and engaged by a brush 75. The contact 74 moves between projections 70, 71 mounted on a member 69 rotatably mounted on the shaft 60 and the rotation of the member 69 due to the shaft 60 is prevented by means of a spring member 73. When the shaft 60 rotates faster than the shaft 61 the contact 74 engages a contact 72 on the member 69 and which is connected to a slip-ring 77 engaged by the spring member 73. When the controlling drum is in its fourth running position and the contacts 72 and 74 engage the magnet 29 is energized to attract the member 30. The relative movement between the member 30 and the sleeve 8 uncoils the spring 33 which engages the member 50 to drive the shaft 14.

Abstract: 347,854. S e w i n gmachines. SINGER MANUFACTURING CO., Ltd., Singer, Clydebank, CORRALL, H., St. Alban, Helensburgh, Dumbartonshire, and HEGGIE, J., 7, Drumry Road Clydebank. April 9, 1930, No. 11249. [Class 112.] In sewing-machines in which the work-clamp is given longitudinal and transverse movements for the formation of a group of stitches for example in stitching around tabs for attachment to soft collars, the lower member of the clamp is formed as a work-receiving die and the upper member as a clamping foot which may be swung aside to give access to the die. The die 1 is carried by a bar 24 to which the usual movements are given by a cam 31. The upper clamping foot 4 is carried by shanks 6, 7, slidably mounted in a bracket 8 which is pivoted on a pin 9 mounted on the bar 24. During a stitching operat.on the foot 4 is held on the work by springs 12, 13 which engage notches in the top ends of the shanks. At the end of an operation a pedal-operated lever 16 is actuated and causes a bar 20 to rise and free the springs 12, 13. A light spring 14 then opens the clamp, and a spring 21 rocks aside the bracket 8 carrying the clamp foot.
Patent GB-744780-A (GB)
Title: Apparatus for distributing liquid manure and the like
IPC: A01C23/00
Filed: 1953-04-24
Abstract: 744,780. Liquid distributer; valves. FULLER, A. July 20, 1954 [April 24, 1953; May 12, 1954], Nos. 11300/63 and 13828/54. Classes 69 (3) and 135. A tank 1 for liquid manure is mounted on wheels and driven by a vehicle, and is connected through a suction pipe 3 and a valve 5 with an airpump on the vehicle. With the valve in one position the pump draws air from the tank and liquid manure is drawn in through a pipe connected at one end to a connector 26 and having its other end immersed in a liquid manure supply. A float switch in the tank automatically cuts off the tank interior from the pump when the liquid therein reaches the required level. Discharge from the tank is effected via a pipe 27, a manually operated valve 29, a distributer chamber 34 and three outlet pipes 36. The outlet pipes, Fig. 3, are connected to the chamber 34 by flexible ducts, and include horizontal parts with oblique outlets about which are arranged plates 37 with side walls 37a. Each outlet is partly closed by a plate 38 pivoted about a pin 40, and pivotally connected at 45 to a pneumatically operated control device. Each device comprises a length of convoluted flexible tubing 42 with its interior connected by piping 56 to the valve 5. The upper ends of the devices are pivotally attached to supports 49, and by adjusting the valve the air pump may communicate with the interiors of the flexible tubes. The partial vacuum created therein contracts the tubes and the plates 38 are completely withdrawn from the outlets to allow a flushing action. By a further valve adjustment the tubes are vented and the plates return to their partly open position. A rod 50 is pivoted to each plate and slides through a support 49, and a compression spring 53 on the rod biases the plate towards the closed position. In a modification, Fig. 5, each discharge pipe has a downwardly extending outlet partly closed by a flat plate 66 mounted at the end of a lever 68 pivoted at 69. The other end of the lever is connected to one end of a pneumatic control device similar to that described which is pivoted at 48 to a support 49. Withdrawal of air from the device causes the withdrawal of the plate 66 from the outlet, and a spring 71 within the tube 42 biases the plate to the partly open position. A canvas shield 72 surrounds each outlet. The float switch, Fig. 2, includes a dome 6 with a detachable cover 7 through which extends a pipe 14 connected to the suction pipe 3. Cylindrical walls 12, 13 extend from the cover, and the outer wall 12 supports a plate 23 and a spider 16 through which passes the spindle 17 of a valve head 18. A float 25 fixed to the spindle moves into the lower part of the wall 12 during the latter part of its upward movement and, in consequence, the tank interior is cut off from the pump and the float is sucked upwardly causing the valve head to move against the wall 13.

Abstract: 1,224,840. Barrel locks. TOKAI RIKA DENKI SEIKSAKUSHO K.K. 3 March, 1969 [1 March, 1968], No. 11318/69. Heading E2A. A combined steering lock and ignition switch has an additional detent 15 which prevents engagement of the steering locking bolt 22 when the key 8 is turned to the locking position, until the key is withdrawn from the barrel 7. The barrel is connected to a controlling shaft 10, journalled at 4, connected at its far end to the control switch 25, and has a transverse slot 12 accommodating the detent 15. The bolt is L-shaped and is pressed down against spring 24 by two cam surfaces 13a and 14a on the shaft 10. As the key enters, its end presses back a spring- loaded sliding pawl 17 in the detent 15. As the key is turned, with the barrel and shaft 10, through 90�, the detent 15 rides round a surface 2a, Fig. 3 in the lock housing 1, and is deflected laterally to the position shown in Fig. 6. At this position the end of pawl 17 is displaced from the end of the key and moves axially beside it. Hence, when the barrel is returned to the locking position, the pawl 17 lodges under the key-end as shown in Fig. 8, thus holding the bolt down, against spring 24, by its foot-portion 23. When the key is withdrawn, the pawl 17 and is carrier. - the detent. 15, are released and the bolt 22 flies up to lock the steering Column.

Title: Improvements relating to frequency discriminating electrical apparatus
IPC: H03D3/22
Filed: 1942-08-14
Abstract: 558,482. Frequency discriminators. STERLING, L. Aug. 14, 1942, No. 11414. Convention date, Aug. 15, 1941. [Class 38 (iv)] [Also in Groups XL and XXXVI] In a frequency-discriminator. of the type described in Specification 487,913, [Group XL], in which voltages which are both of input frequency but have a phase relationship which depends on the deviation of this frequency from a standard value, are developed on two control grids, e.g. of a hexode valve, each grid circuit comprises a parallel resonant circuit tuned to the standard frequency and at least one of them passes grid current but has such a low impedance that the voltage developed at the grid by the rectified current is negligible. As shown, received frequency-modulated signals pass via a frequency changer 15 and I.F. amplifiers 18, 19 to a hexode frequency discriminator 20. The grid 25 of the latter is so biased that substantial grid current passes on the positive half-cycles but no bias resistance is used and the resistance of the input circuit is made as low as possible. The other signal grid 26 may or may not pass current. As an alternative to providing a transducer 21 in the plate circuit, the amplitude-modulated radiofrequency component which, as shown, passes to earth via capacitor 34, may be made use of by providing a high radio impedance in the anode circuit and a detector e.g. a separate diode in the hexode envelope. Automatic frequency-control-When the I.F. carrier deviates owing to oscillator drift &c., a steady or slowly varying voltage is developed across resistor 36 in the anode circuit of the discriminator. This resistor is included in the anode circuit of oscillator 37 supplying the frequency-changer and by modifying the anode voltage of the oscillator valve and so its transconductance modifies the effect of its reflected reactance on the tuning of tank circuit 38, 39 in such a direction as to nullify the deviation. Audio currents are excluded from the A.F.C. circuit by a filter 42, 43. The Specification as open to inspection under Sect. 91 comprises also (a) a transmitting station in which the oscillator is stabilized in the same way as the heterodyne oscillator described above and the oscillations are modulated by means of reactance tube shunting the oscillator tank circuit, Fig. 2 (Cancelled) (not shown), and (b) a discriminator similar to that described above but in which the stabilizing voltage is derived from a resistor in the screen grid circuit, Fig. 3 (Cancelled) (not shown). This subject-matter is not included in the Specification as accepted.

[Class 103 (i).] The electromagnetic rail brakes of a vehicle are rendered inoperative automatically when the speed has fallen to a predetermined value. The device is applicable to brake systems in which the rail brakes are brought into operation by an emergency application of the fluid-pressure brakes of the vehicle. In the Figure, the circuit m of the rail-brake magnets includes a relay switch g which is closed at normal speeds since the hand switch b and the centrifugally controlled switch d in the relay switch circuit a are closed. If in these conditions, the pressure in the brake pipe L is reduced to the value corresponding to emergency braking, the switch f closes the brake-magnet circuit which, however, is opened by the switch d when the speed falls to the lower value. The relay switch g may be dispensed with, and the switch d be in the brake-magnet circuit.
