IPC: A01C7/12
Filed: 1937-06-03
Abstract: 496,728. Delivering materials from hoppers. O'CONNOR, A. W. L. June 3, 1937, No. 15388. [Class 78 (i)] [Also in Group I] Seeds &c. are fed from a hopper into a groove in a cylindrical member which is given an oscillating movement about its axis to deliver the seeds to a shoot. Fig. 1 shows a. hopper 1 delivering seeds to a groove in a cylindrical member 4, the axle 3 of which is given an oscillatory motion. The member 4 may be provided with a number of grooves of different sizes any one of which may be brought beneath the hopper by shifting the member 4 along the axle 3 and fixing it in position by a set screw 8. Fig. 5 shows an implement fitted with the device shown in Fig. 1 and provided with means for oscillating the member 4. The oscillating mechanism comprises a wheel 17 carried by a spring controlled arm 18 and frictionally driven from the land roller 15. A connecting rod 19 is pivoted at one end on an eccentric pin 20 on the wheel 17 and at the other end has an adjustable slotted connection with an arm 21 projecting from the axle 3 of the grooved member 4. The seeds delivered by the member 4 fall down a shoot 11 into a furrow made by a tool 23. A furrow closing device 24 is situated behind the shoot 11. The tool 23 and device 24 are vertically adjustable. The roller 15 may be replaced by a dished roller in which case the wheel 17 is provided with a bevelled edge adapted to engage the oblique face of the roller. The wheel 17 may be disengaged from the roller 15 by a cable 28 which is connected to the arm 18 and to a lever 27 on the handlebars 25. The latter are hinged at 23 and can be folded for transport. Fig. 7 shows an alternative method of oscillating the axle 3 in which a weighted lever 29 engages a cam 34 on a land roller 15 and is connected through a lever 31 to the arm 21 projecting from the axle 3. A track marker 36 is provided on the implement shown in Fig. 5, and may be raised, as shown, into an inoperative position. The distributer may be arranged on a garden roller and hoes and other tools may be attached. Fig. 3 shows a modification in which the oscillating grooved member consists of a ring 37 which is held removably between two members 4a 4b. The screw 8 can be loosened and the member 4b removed and a ring having a groove of different size substituted for the ring 37. The tools for making and closing the furrow may be secured to the shoot 11 and casing 2 as shown in Fig. 4, the furrow making tool 23 being adjustable vertically by a screw 45 and the furrow-closing tool 24 being carried by an adjustable pivoted arm 49. The hopper and oscillating grooved member 4 may also be used for feeding birds, the perch being coupled to the axle 3 so that the weight of the bird causes the member 4 to oscillate and drop a small quantity of seed on the ground.

Title: Improvements in and relating to record players
Inventor: WALKER RONALD
IPC: G11B3/08

Abstract: 968, 524. Gramophones, starting and stopping. B. S. R. Ltd. March 25,1963 [April 24,1962], No. 15466/62. Heading G5R. In a gramophone means are provided whereby movement of the pick-up arm away from the axis of the turntable causes the turntable to start rotating, and rapid radial movement of the pick-up arm at the end of a record causes the turntable to stop rotating. Referring to Fig. 4 an arm 46 is attached to the pick-up arm 30 so that anti-clockwise rotation of the pick-arm causes arm 46 to engage a pin 51 on lever 49 and rotate lever 49. This rotation causes a second pin 50 on lever 49 to bear against the inner end 29 of a switch arm and move it in-. wards. The switch arm is provided with an elongated slot 36 which is engaged by a pin 37 carried by one arm 20 of a switch lever. The end of this arm is coupled to one end of a toggle spring 22 so that movement of the arm past the dead centre position causes the arm to snap into the on position; the end 16 of the other arm 17 of the switch lever then causes the jockey pulley 9 to engage a driving spindle 8. As the pick-up approaches the end of a record track a peg 47 on arm 46 comes into engagement with a guide surface 53 on the switch arm. The effect of a friction member 52 provided between the switch arm and the switch lever is such that the pressure of peg 47 tends to rotate the switch arm about pin 37 so that a projection 54 is moved towards a cam provided on the turntable spindle 5. The pressure of the cam will normally cause rotation of the switch arm in the opposite sense, but a rapid radial movement of the switch arm at the end of a record causes the projection 54 to engage the cam which displaces the switch arm into the off position.

IPC: B62D11/10
Filed: 1966-04-07
Abstract: 1,142,531. Change-speed control. BOFORS A.B. 7 April, 1966 [26 April, 1965], No. 15800/66. Heading F2D. A hydromechanical change-speed system for a crawler tractor transmission comprises a rotary-sliding manual control member 23, 25, the rotary movement of which operates, through bevel gearing 26, 27, a rotary ratio selector valve 29 and the sliding movement establishes the drive through the main clutch 46. Mechanical transmission.-The arrangement shown comprises a disc clutch 46 with locking brake 50 arranged between the engine and a six-speed gear train 47. The latter comprises forward and reverse control clutches 62 operated by a double-acting hydraulic piston actuator 57, and ratio clutches 73, 81, 113 operated by actuators 71, 78, 107 respectively. Hydraulic control system.-Pressure liquid is supplied by an engine-driven pump 11 connected by lines 12, 13 to the main control valve 14, the latter comprising drive clutch and ratio clutch control valves 31, 32 connected to the shaft 25 of the gear change member. Valve 31 consists of opposed spring-loaded members 37, 38 controlling the pressure supply to the drive clutch line 45, while valve 32 controls supply lines 56, 119 to the forward and reverse actuator 57 and a line 65 connected to the rotary selector valve 29, Fig. 5 (not shown). The latter communicates with the ratio actuators 71, 78, 107 by lines 69, 117, 77, 112, 115. Valve 14 also includes a spring-loaded pressure regulating valve 16 and blocking valves 75, 85 which normally prevent release of a ball detent 88 limiting axial movement of valve 31. In addition valve 32 is acted upon by a retarding dashpot latch 94 to delay the initial movement of the valve and commencement of gear shift. Operation.-In neutral the clutch 46 is non- pressurized and held locked by brake 50, while valves 31, 32 are engaged by detent 88 and retarding latch 94. To engage gear, control member 23 is first rotated to the desired setting so that valve 29 makes communication with the required ratio actuator 71, 78 or 107, and is then moved axially in the forward or reverse direction to the limited extent allowed by detent 88. Liquid from the valve pressure chamber 33 then passes via valve 37 or 38 to line 45 and main clutch 46 which is permitted to slip due to release of brake 50. At the same time pressure in lines 56, 119 conditions the forward and reverse actuator 57, and in line 65 causes engagement of the appropriate ratio clutch. Pressure build-up then operates valves 75, 85 to release detent 88 so that valve 31 may be moved to the fully open position and thus allow maximum pressure to be supplied to clutch 46 to establish the drive. Member 23 may be moved to a setting in which the rotary valve 29 is connected to exhaust and the blocking valves 75, 78 are by-passed to allow full control pressure to be applied to the main clutch 46.
