Title: Improvements in or relating to apparatus for automatically playing gramophone records
IPC: G11B17/02
Filed: 1945-11-05
Abstract: 619,132. Magazine gramophones. METCALFE, C., and RAE, A. J. Nov. 5, 1945, No. 29291. [Class 40 (ii)] In a magazine gramophone, particularly of the type described in Specification 617,864, having a frictionally controlled tap-tap lever adapted to be tripped by the exaggerated movement of the pick-up arm at the inner part of a record to initiate the automatic recordchanging cycle, a wheel 2 carries a pin 25<SP>1</SP> which positively resets a lever 10 carrying the tap-tap lever 11, to its correct starting position during said record-changing cycle, in order to avoid overshooting and consequent false operation which may occur when light frictional control, necessary with lightly damped pickups, is employed. The invention has a particular reference to the kind of apparatus described in Specification 562,650 in which the exaggerated movement causes a gravityoperated clutch to effect engagement between the motor and the cycling cam. During playing of a record the lever 10, which is frictionally coupled to the pick-up arm mounted at point 4, is slowly moved so that a rubber roller 14 on the tap-tap lever 11 comes into contact with a lug 24 on a wheel 23 rotated by the turntable. When the exaggerated movement occurs, the nose 15 of the tap-tap lever 11 moves into the path of the lug 24 and causes a pin 13 on the tap-tap lever 11 to be moved against the tension of a spring 12 to displace shutter lever 17 and clutch lever 21 coupled together by a pin 25, so that a lug 18 on the end of shutter lever 17 is moved out of the slot 19 in a shutter 20 mounted on a shaft driven by wheel 1. At the same time, a lug 22 on the clutch lever 21 releases a part 3 of a gravity clutch, so that wheels 1, 2 which control the automatic mechanism, are brought into operation. During the automatic cycle, the lug 18 is pressed against the periphery of the shutter 20 by spring pressure. When the pickup arm is moved to the outermost position, the lever 10 is brought to rest against the stop pin 25<SP>1</SP>, as in the position shown in Fig. 1. At the conclusion of the automatic cycle when the pick-up has been lowered on to the record, the lug 18 enters the slot 19, and the lug 22 on the clutch lever 21 passes beneath one of cams 261 and lifts the part 3 of the clutch to disengage the drive to wheels 1, 2. In a modification described with reference to Fig. 3 (not shown), a spring-loaded lever 27, coupled to levers 17, 21 by the pin 25, is included, whereby the turntable is uncoupled from the rest of the mechanism, by the withdrawal of the clutch, as soon as the motor is switched off, so that the inertia of the turntable does not cause the mechanism to be driven beyond a desired position.

Filed: 1956-09-26
Abstract: 803,303. Elevated rail switch points. ALLEN, C. J. Sept. 26, 1956 [Oct. 5, 1955], No. 29444/56. Class 104 (2). In an elevated rail switch with the switch blade moved from an inoperative position to an operative position in which its entry end overlies the main rail to form a track interconnecting the main and branch rails, lifting means engage the load carriers at points other than their part normally bearing on the rail so as to lift the load carriers clear of the entry end of the switch blade as they advance thereover. In the arrangement shown in Figs. 2-4 the continuous main rail 1 is interconnected to a branch rail 2 by switch blade 11 the under side 15 of which blade 11 rests on the upper surface 16 of the main rail 1 when in the operative position. The load is suspended from C- shaped skids, Fig. 1, provided with a downturned lip 6 the underside of which is rounded or convex. When the blade 11 is in the operative position the lip 6 engages an inclined surface 35 on a member 33 secured to the blade 11 as the skids move from the position 20a to 20b, Fig. 3. On further advancement of the skid to the position 20c the lip 6 moves up the inclined surface 35 to lift the horizontal portion 5 of the skid above the entry end 19 of the blade 11. Further advancement of the skids to the position 20d enables the lip 6 to move along a flat portion of the member 33 and the horizontal portion 5 of the skid 6 to contact the inclined upper surface of the blade 11 so that the skid may now be further advanced over the blade 11 to the branch rail 2. The end of the blade 11 adjacent the branch rail 2 is attached to a member 21 pivoted at 12 to the branch rail 2, Fig. 5. The end of the member 21 is bent outwardly to form an operating handling 25 and carries a tumbler block 26 pivotally mounted on pin 27 in such a manner that when the upper edge 29 of the block 26 moves to the position below the lower edge of the branch rail 2 the block tilts to the position shown in Fig. 4 to hold the blade 11 in the inoperative position. The block 26 is retracted by a handle 32. The adjoining ends of the blade 11 and the branch rail 2 are curved to permit the blade 11 to pivot. In a modification shown in Figs. 9 and 11 the skid 49 is lifted over the entry end 39 of the switch blade 37 by the inclined surface 61 of a block 60 attached to the end of a support arm 57 secured to and spaced from the switch blade 37. The switch blade 37 is attached to an arm 45, Fig. 11, through the intermediary of spacing pieces 47. The arm 45 is pivotally mounted at 44 on an overhead bar 43. A pivoted arm 52 moves the switch blade 37 to the inoperative position or releases it to the operative position on passing through a dead centre position. The device may also be used with wheeled trolleys.

C., 13, Leathley Road, Hunslet, both in Leeds. Oct. 25, 1935, No. 29546. [Classes 78 (iii) and 78 (v)] [See also Groups I and XXXI] A hydraulic transmission gear, which is interposed between the prime mover and the drum of a winding or hoisting-gear, comprises a casing supporting a cylinder in communication with its interior, a piston in the cylinder carrying a rack which drives a pinion on the winding-drum shaft, and a pump adapted to drive the piston. As applied to an agricultural tractor or like machine for hauling on chains adapted to raise and lower the digging or like implements, the closing of a clutch 26 by hand operation, drives a pump shaft 22, thus causing the pump 23 to draw oil from the bottom of the gear casing 1 and force it into the cylinder 2 thereby depressing the racked piston 43 and rotating the shaft 40 through the medium of the pinion 41. Drums 47 on the shaft 40 wind up chains to raise the implements. At the lower end of its stroke the piston releases the clutch automatically. When the clutch-operating lever is moved into position for lowering, it operates a relief valve automatically, thereby allowing the weight of the load to force the piston upwards and return the oil to the gear casing. The sleeve 24, carrying one element of the clutch, is driven from a shaft 8 in line with and coupled to the propeller shaft of the tractor.

Abstract: 882,791. Clutch control. EDDY, W. C. Sept. 1, 1959, No. 29819/59. Class 80 (2). [Also in Group XXII] A torque responsive control arrangement reverses the direction of rotation of the tool of a machine tool upon overload, which is driven by a reversible pneumatic motor 12. On the occurrence of overload an electric circuit is completed to reverse a valve 132 controlling the supply and exhaust of air to the motor 12. At the same time a solenoid operated valve 72 is actuated to open the cylinder of a clutchoperating piston 60 to exhaust so that a friction clutch 30, 32 in the drive to a chuck 14 is disengaged by a spring 54. A time-delay relay subsequently opens the circuit to the valve 72 so that air pressure is applied to the piston 60 to re-engage the clutch so that the chuck is driven in reverse. The driven plate 30 of the clutch is connected by a spring 110, which yields on overload, to a shaft 34 driving the chuck. When the spring yields a contact arm 118 fast with the clutch plate 30 engages a contact 119 or 120 adjustably mounted on the shaft 34 to complete the electric circuit. Adjustment of contacts 119, 120 varies the maximum torque transmittable. As described, the mechanism is applied to a tapping machine and the shaft 34 drives the chuck through a pin-and-slot connection, allowing axial movement of the chuck so that the tapping die can feed itself on to the work. Limit switches are included in the electric circuit for reversing the motor at the ends of the stroke of the chuck.
