Title: New or improved multi-ratio transmission mechanism for vehicles
Inventor: ASHFIELD HERBERT EDWARD
IPC: F16H61/02
Filed: 1959-10-19
Abstract: 917,593. Change-speed and clutch control. BROWN TRACTORS Ltd., DAVID. Jan. 2, 1961 [Oct. 19, 1959], No. 35251/59. Class 80 (2). A vehicle transmission comprises a changespeed gear with clutches or brakes controlled automatically in accordance with engine or vehicle speed by the sequential operation of a series of differential valves in response to variations in the pressure of the delivery from an engine or vehicle driven positive displacement pump. Mechanical transmission.-The arrangement shown for a tractor drive comprises input and output shafts 14, 35 and two epicyclic gear units 10, 11 in series, with fluid-pressure disc clutches 18, 29, respectively, giving provision for four gear ratios. The shaft 35 carries: a pair of spur pinions 36, 37 meshing with pinions 38, 39 on a drive-shaft 40 carrying a reverse pinion 43 and a dog-clutch 42 for establishingthe final drive through pinion 38 or 39. The gear unit 10 consists of axially spaced sun pinions 13, 16 meshing with stepped planet pinions 15 on a carrier 17 which is rotated by engagement of clutch 18; gear unit 11 is of similar construction with sun pinions 24, 27 meshing with planet pinions 26 on a carrier 28 operated by clutch 29. One-way roller clutches 23, 34 are provided in the respective units. Hydraulic control system.-The delivery from an input- or output-driven gear-wheel pump 58 is fed through conduits 20, 31 to the clutches 18, 29 under the control of spring-loaded valves 46, 47, 48 which are of the differential type in order that they may operate at higher opening pressures than closing pressures. A piston valve 65 is positioned as shown by a manual override lever 81 so that the pump delivery passes through a calibrated orifice 68 before entering sump and lubricating passages 70, 71. Initially both clutches 18, 29 are disengaged for highest gear ratio, increasing pump pressure with speed first causing valve 46 to open and engage clutch 18, then causing valve 47 to open and valve 46 to close, to engage clutch 29 and release clutch 18, and finally causing valve 48 to open and thus re-open valve 46, so that both clutches are engaged for direct drive. The operation is reversed when speed falls. Manual control.-Upon raising hand lever 81 to depress valve 65 a passage 85 is uncovered to by-pass orifice 68, and at the same time the loading is varied of a spring 89 acting on a valve 87 controlling the flow through passage 85, whereby the valve operating pressure and thus the particular gear ratio engaged is determined solely by the position of lever 81.

Abstract: 639,932. Magazine gramophones. GARRARD ENGINEERING & MANUFACTURING CO., Ltd. Dec. 5, 1946, No. 36047. Convention date, March 18, 1942. [Class 40 (ii)] In a magazine gramophone a stack of records to be played is supported on a rod 5 by an eccentric tooth 1a on a supporting shaft 1, which is rotated 150 degrees in each direction during a record-releasing operation so that the entire stack is first lowered by a distance corresponding to the height of the eccentric tooth 1a and the lowermost record then drawn sideways by the eccentric tooth 1a out of alignment with the remainder of the stack into alignment with the supporting shaft 1, so that it falls to the turntable 19. The pick-up arm is swung outwardly by a cycling cam-disc 7 and is lifted and lowered by means of a cam 48 on a shaft 10 coupled to the cam-disc 7 by bevel gears 8, 9. The supporting shaft is rotated through 150 degrees by means of a crank. 16, levers 14, 17 and a cam-roller 12 on the cam-disc 7. The initial setting of the stylus on the record is controlled by the size of the record being released from the stack supported on the shaft 1. When the eccentric tooth 1a pushes a 12-inch record towards the pick-up arm pivot, the edge of the record comes into contact with the upper end of a lever 30, which pivots about a screw 31 and moves a lever 26 into a position in which a pin 33 may intercept a lever 22 on the cam-disc 7, Fig. 4, so that the latch members 34, 36 become interlocked, as in Fig. 5, and the wall 45 engages the pin 43 on the pick-up control arm 40, and moves it to the starting position for a 12-inch record. When a 10-inch record is released on to the turntable, the edge of the record does not come into contact with the lever 30, the lever 22, 23 remains in the unlatched position shown in Fig. 4, so that the wall 45 engages the pin 44 on the pick-up control arm 40, and moves to the starting position for a 10-inch record. The turntable 19 is mounted on a bearing 3 surrounding the supporting shaft 1 and is driven by means of a pinion 2.

Abstract: 368,707. Code telegraphy. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. Dec. 1, 1930, No. 36219. Convention date, Dec. 2, 1929. [Class 40 (iii).] A non-polarized relay is arranged to respond to selective or telegraphic impulses resulting from the connection of alternate positive and negative potentials to a single wire. Fig. 1 shows a telegraph exchange system in which such a relay responds to selecting impulses. When the polarized relay ER energizes over the incoming line L, relay R1 pulls up and the preselector VW rotates under control of the magnet D1 and test relay Tl and seizes an idle connector LW. With relay ER energized, impulse relay A1 energizes over winding I and locks over winding II in series with relay J1, winding I being thereby connected to positive instead of negative potential. When relay ER falls back in response to each impulse, reverse current flows through winding I and nullifies the effect of winding II, thus causing relay Al to relapse. The connection is completed over the connector LW in known manner, and telegraphic impulses are repeated in either direction by the polarized relays ER, ES. Fig. 2 shows a modification in which relay J1 is dispensed with, while in Fig. 3 the relay A3 has a single winding and is normally traversed by a small opposing current which serves to effect rapid release when the energizing current ceases although insufficient to energize the relay.
