Title: Self-contained hydraulic means for driving gramophones
IPC: G11B19/00
Filed: 1926-10-27
Abstract: 284,029. Johnson, O. C. Oct. 27, 1926. Driving; starting and stopping; speed ,regulating.-A gramophone is driven by a motor comprising a compressible spring S acting on a piston E in a cylinder B containing oil or other fluid, the fluid being forced, as the spring expands, through ports H<3> in a valve ring H fixed in a casing B<1> above the cylinder, into oscillating members K, pivoted on the ring and having cylindrical arms in which piston rods T work; these arms carry sleeves N, which are connected to the pistons T and which are all coupled to a crank-pin 0 on an arm O<1> fixed to a shaft O<2> supporting the turntable O<4>. Exhaust ports H<4>, formed in the ring H beneath the members K, lead to the inside of the ring, while the inlet ports H<3> all communicate with a circular groove H<2> connected by a duct Z to the cylinder B. An orifice B<2> connects tha interior of the ring to the portion of the cylinder B containing the spring. Thus as the sleeves N reciprocate, driving the turntable, the members K are oscillated, putting the inlet and discharge ports H<3>, H<4> alternately in communication with the cylindrical passages in which the rods T work. Power is stored in the spring S by mechanism which may be actuated by movement of the lid of the gramophone casing. The mechanism comprises bell-crank levers C<\> C<2>, which are both secured to a shaft C', free to turn in a bearing or collar C' slidably mounted on a rod C<6>. The short arms of the bell-crank levers are connected, through links C, to the outer end of the piston-rod E<3>. With the spring S unstressed, as shown, the collar C<5> is engaged by a pivoted detent C<7>, held in locking position by a spring S<1>. To start the machine, the upper ends of the levers C<2> are depressed, for example by closing the lid of the casing, (which may be connected to the levers for this purpose), and the piston E is thereby moved along the cylinder B, compressing the springs S, whilst oil flows past the piston-head. Then the detent C<7> is moved so as to release the collar C<5>, and the spring expands, driving the machine as previously described. The release movement of the detent C<7> is effected by rotating a rod G by means of a handle G<2>, the rod carrying a pin G<1> which depresses the outer end of the detent. At the same time, a friction pad G<3> is moved away from the turntable. The speed of the machine is governed by providing on the turntable spindle O<2> radial extensions of the arm O<1>, the ends of which have attached thereto, by means of leaf springs, weights P' carrying friction pads. The pads bear against a coned surface P<3> on the inside of the casing, and the vertical position of the friction pads relatively to the surface P<3> is varied as desired, to control the speed, by raising or lowering within the casing a bush O<6>, together with the spindle O<2> passing through it, and all the parts carried by the spindle. This vertical adjustment is effected by means of a rod M<2> passing through an oblique slot in the casing.

Title: Accumulating and distributing conveyor for food products
IPC: B65G47/30
Filed: 1973-06-06
Abstract: 1414427 Endless conveyers TOBY ENTERPRISES 6 June 1973 27002/73 Heading B8A An accumulating and distributing mechanism for correcting for random fluctuations in the delivery of objects to an object demanding mechanism from an object supplying mechanism comprises a pair of intersecting conveyers, means for detecting a space greater than a predetermined space between successive objects on the first conveyer and means responsive to such detection to move the point of intersection of the conveyers in the direction of flow of the objects. In Fig. 1, stacks of meat slices are delivered from slicer 13 to first conveyer 18 which comprises a plurality of chains 28 (Fig. 2). Second conveyer 19 comprising a plurality of chains 32 (Fig. 2) intersects conveyer 18 at a point of intersection formed by guide rollers mounted on a carriage 37 which is movable along the path of the conveyers by a chain loop 99 (Fig. 2) driven by motor 57 which also drives the conveyers by means of chains and sprockets. A gap between successive stacks is detected by detector 129 on carriage 37 and this causes the carriage drive to be connected to the motor so that the carriage and hence the point of intersection " follows " the last stack at the predetermined spacing. Meanwhile conveyer 18 is driven at twice the speed of conveyer 19 and carriage 37 until the next stack on conveyer 18 arrives at the point of intersection, when the stack is transferred to conveyer 19, and carriage 37 moves against the direction of flow until it is the predetermined distance behind the stack which has just been transferred, in order to correct for the next gap in the flow. Stacks are discharged singly to a packaging machine, entry to the drop zone being controlled by detector 127 which stops conveyer 19 if the packaging machine is not ready for delivery of a stack. Rollers mounted in pairs on tubular supports (see Fig. 2) receive a stack, the supports rotate downwards through 90 degrees and the stack drops through the gap so formed to a receiving station of the packaging machine.
