Title: Improvements relating to means for transferring articles from one moving conveyor toanother
IPC: B65G47/82
Filed: 1949-12-07
Abstract: 680,559. Endless conveyers. PALETHORPES, Ltd., and PALETHORPE, J. Dec. 5, 1950. [Dec. 7, 1949] No. 31373/49. Class 78 (i). Means for transferring articles from a first moving conveyer to a second moving conveyer comprises a stationary support arranged alongside the first conveyer and across the second conveyer and a push bar arranged along the support and carried by a plate which is guided by means of pins on its underside engaging tracks on the support, such that movement of the plate along the support from one end to the other is accompanied by lateral movement which causes the push bar first to move away from the support so as to push the articles from the first conveyer to the second conveyer, and then to move back towards the support, and that return movement of the plate along the support is unaccompanied by lateral movement so that the push bar remains out of contact with approaching articles on the first conveyer. Cooked, or uncooked pies a, Fig. 2, are transferred from an endless belt b to a transversely extending endless belt c by means of a push bar f which is movable in a closed triangular path, corresponding to a pair of triangular guide tracks i, Figs. 2 and 3, in a clockwise direction corresponding to pies moving from right to left along belt b. The push bar f thus moves with the pies on belt b during transfer and returns parallel to belt b and out of the parth of the pies. The bar f is carried by a plate e mounted on balls g running in triangular recesses 2 in a fixed support d on which the guide tracks i are provided. Each guide track i is formed by the peripheries of a triangular recess j and a triangular member k pivotally mounted on a vertical pin and urged anticlockwise by a spring n so as to determine the sense in which a peg h depending from the plate e is guided around the track. As plate e is reciprocated along the support d the two pegs h run along the two inclined sides in the direction of movement of belt b, of each track i, and along the third aligned side of each track i in the reverse direction. A pawl u connected by a strap t to the plate d is adapted to be engaged by a peg x on a supporting pulley v of the belt b to move plate e in the direction of belt b, and after moving the appropriate distance is released from the peg x by a stop y co-operating with an arcuate guide w, plate e being returned to the initial position, Fig. 3, by a weight q acting on a cable r passed over a pulley s and connected to the plate e. The base of each recess 2 for the balls g is of plate glass or like material and similar triangular recesses 3 facing oppositely to each recess 2 are provided in plate e opposite each recess 2 for resting on the balls g and are similarly formed with a glass or like base, the plate e being preferably cut away so that the balls g are visible through the glass of the recesses 3.

Title: Rotary automatic welder
IPC: B29C65/02
Filed: 1974-07-16
Abstract: 1471010 Seaming non-metallic sheet material M MIKAMI 16 July 1974 31390/74 Heading B5K A rotary welder comprises a verticallymovable fusion-welding bar 13, Fig. 5, and a plurality of fusion welding beds 4 spaced about the periphery of a rotatable drum 1, Figs. 1 and 4, and having bed plates locked on the opposite ends of the drum 1 by plates 6 so as to be adjustable about the periphery of the drum 1. As shown, the drum 1 is mounted on a shaft 2 and has a circular T-section groove 3, Fig. 4, cut on each end thereof to receive T-bolts and nuts 7 to retain the plates 6. The bar 13 is mounted on a block G, Fig. 1, movable vertically by a cylinder H. The bed plate of each bed 4 has a contact member 14 to contact a limit switch 15 as the drum 1 rotates. In operation, to weld strips Q, Figs. 3 and 5 (the former not shown), of holding cloth to a motor-vehicle head-lining cloth P to form pockets for receiving listing rods, the strips Q are each located in a bed 4 and clamped by plates 5, Fig. 5, and the desired number of beds 4 are spaced about the drum 1. Rotation of the drum 1 commences and when the switch 15, Fig. 1, is contacted by a member 14, a clutch K is disengaged and bars 10 are projected by air cylinders 11 to be received in openings 8, Fig. 4, in the plates 6 to stop the drum 1 at a predetermined position. The block G is lowered and guide bars 12 thereon are received in openings 9 of the bed plate of the bed 4. Welding is effected by high frequency current applied for a predetermined period using the bar 13 and a bed 4 as electrodes. After cooling for a predetermined time set by a timer, the block G is raised so that the clutch K is engaged to rotate the drum 1 to position the next bed 4 for welding.

Title: Improvements in and relating to a method and an apparatus for mechanically cracking eggs
IPC: A47J43/14
Filed: 1964-08-04
Abstract: 1,027,663. Opening eggs. J. T. KLINT Aug. 4, 1964 [Aug. 3, 1963], No. 31463/64. Heading A4R. A method of cracking eggs comprises resiliently supporting an egg by pressure in the direction of its longitudinal axis, additionally supporting the egg on a narrow edge at about mid length, and lightly pressing diametrially opposite the narrow edge to press the egg over the edge. A machine comprises contra-rotating discs 1 2 carrying co-operating egg gripper units 5. In operation, eggs are fed singly from a conveyer through side openings 19 in cups 14 to be resiliently gripped between co-operating pairs of cups 14 as they are brought together by the rotary discs 1, 2. The eggs are additionally supported on the edges 22 of knives 21 pivotally mounted, as at 26, and having their movements controlled by cams 39, 41 fixed discs 6, 7 associated with the rotary discs 1, 2 respectively. The thus supported eggs are pressed over the knives 21 by further knives 30 carried in spring biased blocks 29 carried by a stirrup 25 pivoted, as at 26, to the frame of the gripper unit 5, and being controlled by cams 40, 42 and 45, 45a. Further rotation of the discs 1, 2 causes division of the egg into two parts, the contents running down a chute to a device for separating yolk and white. Further movement of the grippers past fixed cams 55-58 causes ejection of empty egg-shells in readiness to receive a further egg.

Abstract: 324,955. Baird, J. L., and Television, Ltd. Nov. 7, 1928. Synchronous movements. - A synchronizing device comprises a commutator or rotary switch, which receives an electric impulse emitted at a time in each cycle determined by a transmitting apparatus, and co-operates with brushes or contacts 14, 16, 18, 20, 22, 24 to bring into action successively, on departure from synchronism, devices 30, 28, 26 or 32, 34, 36, which exert on the moving member to be synchronized correcting impulses which increase in degree with increasing displacement from synchronism. The line of contact between the commutator and the brushes is inclined relatively to the edge of a conducting-segment 4 by spacing the brushes diagonally as shown, or by inclining the edge of the segment (Fig. 2, not shown), so that during movement of the commutator the brushes engage the segment successively. According to a modification, a plurality of conducting- segments co-operate with a plurality of brushes and are so spaced and dimensioned that, during movement of the commutator, the brushes engage the segments in a given order, and at any instant not more than one brush is engaged with a segment (Fig. 3, not shown). Specification 320,639 is referred to.
