Title: Improvements relating to signalling apparatus
IPC: F21V11/04
Filed: 1929-05-02
Abstract: 333,169. Aldis, A. C. W. May 2, 1929. Electric lamp and flash signals.-In apparatus of the kind having a plurality of shutters intermittently occulting a light beam the operating springs are energized by a continuously running motor and controlled by an escapement mechanism. The shutters a mounted on rotatable pins c journalied in a fixed ring d have crank arms e engaging with pins 24 fixed to a a ring f rotatably mounted about a spindle 25 on which a lamp b is mounted; the ring f being oscillated, and the shutters opened and closed, by the rotation of a spindle j having a crank pin g mounted on an arm i engaging with a slot h in the ring f. The sun pinion y integral with the spindle j, and the sun pinion 2 mounted on a loose sleeve z mesh with pairs of pinions 4, 5 respectively, integral with spindles 6 carried in a rotatable case 7 whose toothed ring 8 engages a pinion 9 mounted on a spindle w. The sleeve z also carries a pinion 3 meshing with a quadrant s whose spindle r carries a lever q whose ends are attached to springs p. In operation the continuously running motor t drives through friction wheels a, v the spindle w which through pinion 9 and gearing 8, 4, 5, 2, 3, the shaft j being held against rotation by an escapement bearing k abutting against one end of the arm i, rotates the quadrant s tensioning the springs p. When a signal is to be sent an electric circuit is closed energizing a solenoid n to lower the bar k and free the arm i which under the action of the springs p rotates 180‹ until its other end is engaged by the bar k in its lower position, see Fig. 3. During this operation the spindle w is held against reverse rotation by a suitable coiled clutch spring 10 and after the arm i has come to rest against the bar k the motor t again energizes the springs p in readiness for the completion of the revolution of the arm i which occurs when bar h is released by the solenoid and returns to its upper position under the action of a spring o. To prevent over-energizing of the springs p, the pinion 3 during tensioning of the springs, through a loose pinion 13, rotates a wheel 12 which rises on a threaded sleeve 11 and carries a bar 15 to push up a disc' 16 integral with the spindle w against the action of a spring 17 thus releasing the friction drive u, v, which is reengaged after the springs have operated the shutters. To minimize shock when the arm i, comes against the bar k, the latter is provided with a dashpot l at its pivoted left end; also the crank pin g is arranged to come to rest in the middle of the slot h so that the motion of the shutters is practically zero when the pin g comes to rest. Additional springs 23 are provided to aid the oscillation of the ring f. The springs pare arranged easily accessible for renewal during operation of the apparatus. In a modification the shutters may be in the form of a flat screen preferably mounted on a revolving platform, or they may be arranged horizontally. Another modification states that skylight instead of a light beam may be obstructed by the shutters.

Title: Method of and machine for handling eggs
IPC: B65B23/02
Filed: 1954-05-13
Abstract: 747,455. Coating eggs. FOOD MACHINERY & CHEMICAL CORPORATION. May 13, 1954 [June 1, 1953], No. 14079/54. Class 49. [Also in Groups XVII, XVIII, XIX, XXX and XXXVII] Eggs to be sorted according to weight and quality, e.g. colour, are conveyed along a predetermined path and discharged therefrom at appropriate points by means controlled by a record of the weight and quality of the article. An operator takes eggs from boxes delivered by a conveyer 100, Fig. 1, candling each by viewing it against a light 106, and placing it in the appropriate one of eight racks 108a .... h. each rack corresponding to a different colour or quality. Adjacent these racks is an elevator carrying cups 112, and as an empty cup reaches a rack containing eggs, one of the eggs rolls into the cup and in doing so closes a contact which records the quality of the egg on a " memory device." At the top of the elevator, each egg is transferred to a weighing cup 118 and its weight is recorded on the " memory device." The egg is then transferred to a horizontal conveyer 122 which extends across transverse conveyers 124, 126 divided into eighteen lanes, each lane corresponding to a different quality/weight combination. As an egg on conveyer 122 reaches the lane corresponding to its quality and weight, a solenoid is actuated by the " memory device " to tip the cup and transfer the egg to the conveyers 124, 126. From conveyers 124, 126, the eggs pass to a conveyer 138 where they are rotated and sprayed with a sealing liquid spray (" oiling "), and thence to shoots feeding egg accumulators which are automatically depressed as each row is filled, and when completely full, close a gate which is only opened when an empty accumulator is in position to receive eggs. Eggs' from the conveyers 124, 126, Fig. 1, pass to the further conveyer 138 where they are coated with oil from a spray not shown. Conveyer 138 is similar to conveyers 124, 126, comprising rods transversely attached to chains; the rods have enlarged portions defining lanes; in addition, the rods are caused to rotate by pressing against rubber strips so that the eggs are rotated in their traverse. To enable conveyers 124, 126 to be positioned close to the " oiling " conveyer 138, sprockets have three teeth of greater height than the intervening teeth so that the links between two transverse rods may bend sharply. To transfer the eggs from conveyers 124, 126 to the " oiling " conveyer 138, a vane extending the whole width of the conveyers 124, 126 may be rotated by sprockets to intermesh with the transverse rods and push the eggs over the junction. A similar arrangement is provided at the exit of conveyer 138. Rubber aprons cushion the eggs against breakage. The lanes on the oiling conveyer are preferably separated by ribs.
