Title: Improvements in egg handling plant
Inventor: ROSTRON FRANK
IPC: B65B23/06
Filed: 1957-06-24
Abstract: 854,055. Endless-chain conveyers. NEWMAN, HENDER & CO. Ltd. May 22, 1958 [June 24, 1957], No. 19866/57. Class 78 (1). Eggs A are arranged with their major axes parallel to one another and with their narrow ends pointing in the same direction by placing them one by one between pairs of rotatable rollers 6 with their major axes substantially parallel to the axes of the rollers, moving the rollers bodily while they are rotating in a direction transverse to their axes to carry the eggs towards a guide 14 and stopping the rotation of the rollers while they pass the guide. The rollers 6 are mounted between a pair of parallel endless chains 3 and each is formed with a neck 7 adjacent one end. Each pair is connected at each end by an arcuate link 8. A spindle 9 fixed to each pair of links 8 passes freely through a central aperture of much larger diameter formed in a roller 10 and a block 10a of square cross-section fixed thereto. Surfaces 12, 12a and 13 disposed below the conveyer determine whether the rollers 6 rotate in one direction or the other, or are stationary. The conveyer moves from left to right, Fig. 2, and in the part above the surface 12, the rollers 10 are in contact with the surface and also with the rollers 6. Consequently the rollers 6 are rotated. As the rollers 10 pass on to the surface 12a, they move away from the rollers 6 and since a side of each block 10a engages the surface, the rollers 10 do not rotate. The rollers 6 also do not rotate and as the eggs are carried past the guide 14, its inclined face acts as a cam and turns them about their long axes. As the conveyer moves into position above the surface 13, the rollers 6 are rotated by contact with it and the eggs move into the depressions formed by adjacent necks 7. The eggs are delivered to the conveyer by shoots 15, 15a and brought into engagement with a rotary feeding device 17 which passes them singly to the pairs of rollers. An escapement device 25 in the shoot 15 retains an egg until an egg arriving by the shoot 15a has been delivered to the conveyer by the feeder 17. The pins of the escapement are mounted on a pivoted rocker 26 having a cam follower 27 which engages a cam 28 keyed to the driving shaft 22 of the feeder 17. Specification 854,054 is referred to.

Title: Improvements in brake and accelerator pedals for motor vehicles
Filed: 1937-07-21
Abstract: 499,750. Controlling motor vehicles ; pedal levers. KING, H. H. July 21, 1937, No. 20134. [Classes 79 (v) and 136 (ii)] Comprises a combination of two pedals, such as accelerator and brake pedals, for motor vehicles and other machines, in which one, e.g. the brake pedal is above, at the forward end of and in the same vertical plane as the other, e.g. the accelerator pedal, and the bars forming the two pedals are interdigitated so as to form a practically continuous surface for the driver's foot to slide along from one pedal to the other. In the construction shown, the acceleration pedal h is pivoted at j on a triangular frame d<3>, which is pivoted at c and is normally held against a stop n by a spring t.. The brake pedal a is interdigitated with the accelerator pedal h and is pivoted at y on the frame d<3> which is directly connected to the brake linkage (not shown), so that when the pedal a rocks the frame d<3> by pressure against the side d<4> the brakes are applied. A spring x normally keeps the pedal a against the side d<4>. The forward end of the accelerator pedal is connected at k to a lever l pivoted at p on the brake pedal and connected at n by a cable q to the throttle (not shown). When the pedal h is depressed the lever l rocks about p and the brake pedal rocks slightly backward about y so that the cable q is pulled and the throttle is opened. When the brake pedal is depressed, or if further pressure is exerted on the accelerator pedal beyond that necessary to open the throttle fully, the throttle is allowed to close by the forward movement of the lever l and cable q, and the brakes are applied. Modifications are described in which (1) the brake pedal and the frame d<3> are integral, and the accelerator pedal acts on the lever l through a lostmotion slot connection, (2) the.brake pedal is formed as a lever, its lower arm carrying a roller which, when the pedal is depressed, engages the under surface of the accelerator pedal and returns it to the closed-throttle position, and (3) a roller on the chassis prevents the accelerator pedal from moving forward with the brake lever except in the closedthrottle position.

Title: Improvements in electrical relays
IPC: H01H51/32
Filed: 1936-07-21
Abstract: 478,654. Electromagnetic interrupters. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd. July 21, 1936, No. 20193. Convention date, Jan. 16. [Class 38 (v)] Electromagnetic interrupters, which may be employed as track or line relays in railway signalling systems employing for the control of the signalling devices direct current which is periodically interrupted or coded at different frequencies have two sets of opposed polepieces magnetized by a permanent magnet and a magnetizable armature extending longitudinally between the sets of polepieces which are so arranged that the polepieces on the same side of the armature are of the same polarity, the armature being movably supported at one end outside the magnetic circuit of the polepieces and armature and the latter being surrounded by an energizing coil between the sets of polepieces. As shown in Figs. 1 and 2, two pairs of polepieces 9a, 9b and 11a, 11b are clamped in magnetic bars 7a, 7b secured by bolts to the main magnetic framework 2. These polepieces are magnetized by a permanent magnet 13 secured to the rear face of the framework 2 by a strap 14 and bolts 15. To the lower end of this member is clamped a spring blade 17 supporting the armature 20 which extends upwardly between the pole faces 10a, 10b and 12a, 12b. Mounted between the pole faces surrounding the armature is a coil 23 to which the supply currents, for example, interrupted D.C. of varying frequencies, is led. Normally the armature is biassed towards the right-hand poles by springs 38a, 38b acting on the contact mechanism, Fig. 3. These springs act on blade members 33a, 33b secured at their ends to brackets depending from the terminal base 1 of the relay, the free ends of the blades 33a, 33b carrying contact blades 32a, 32b co-operating with front and back contacts 44a, 45a and 44b, 45b. The free ends of the contact blades bear against recesses in an insulating member 35 attached to the upper end of the armature and when an interrupted D.C. current traverses the coil the variation of the polarity induced in the armature causes it to vibrate between the polepieces. The polepieces are adjustable and the upper pair are formed with inclined faces so that they may be parallel to the armature in its opposite inclined positions. To prevent sticking of the armature its opposite faces are provided with non- magnetic pins 21. The edges of the members 18 confining the armature-supporting spring 17 may be rounded to prevent damage to the spring during the armature vibration. In an alternative arrangement the lower end of the armature is supported on a knife-edge first. A cylindrical glass casing 4 surrounds the relay, being clamped with interposed gaskets between the upper and lower plates 1, 3.
