Title: Improvements in sheet delivery mechanism for printing presses and like machines
Inventor: SKELLY ERNEST ALBERT JAMES
IPC: B65H31/32
Filed: 1962-10-22
Abstract: 992,675. Delivering sheets. LINOTYPE & MACHINERY Ltd. Nov. 27, 1963 [Oct. 22, 1962], No. 39842/62. Heading B6H. A sheet delivery mechanism includes a main pile support for carrying a first pile board, an auxiliary pile support for carrying a second or subsequent pile board, and means for controlling the sequential lowering of the main pile support by a pile hoist until a selected depth of pile is reached, the pile hoist being actuated by insertion of the second pile board into the auxiliary pile support to lower the main pile support for removal of the loaded first pile board and being actuated by removal of the loaded first pile board to lift the main pile support to a position adjacent the auxiliary pile support to receive the second pile board. The main pile support comprises two spaced cantilever arms 7 connected by a cross-bar 8. The arms are guided by vertical side rails 114 and raised or lowered by screw means 10 passing through the crossbar. The screw means is rotated by a reversible motor 16 through an electromagnetic brake 17. The main pile support is lowered step-by-step as the pile grows, under the control of a sensing switch 49. The latter is mounted on an arm 50 carried by a crossshaft 51. The shaft 51 is rocked by links 52, 53, and a crank 54. The auxiliary pile support comprises two spaced-apart side rails 21 carrying a plurality of rollers 24 on which a second or subsequent pile board is supported. Each side rail is suspended from the machine frame 1 by two arms 22, 23 pivotably mounted on a shaft 34. The side rails are maintained in the position shown in Fig. 2 by spring-loaded latches 44, each engaging a lug 47 on the associated arm 23. The side rails may be pivoted apart to drop the second pile board on to the main pile support, by means of rods 32, each under the control of a solenoid 27. When the rods 32 are lifted a spring 40 encircling each rod is compressed until a collar 42 releases the latch 44, the spring expands to pivot the arm 23 counterclockwise as seen in Fig. 2. In use, the main pile support is lowered step-by-step until it closes a switch (not shown) whereby a visible or audible warning is given. Next a second pile board is placed manually on side rails 21. This closes switches 63, 67. The former switch closes the motor circuit and the main pile support is lowered until the down circuit switch 59 is opened. The loaded pile board 14 is run out by means of a roller conveyer 64. This re-sets switch 58 whereby the motor is reversed and the main pile support raised until it engages the up limit switch 65. The solenoids 27 are then operated, either manually or automatically, and the second pile board dropped on to the main pile support. Automatic operation of the solenoids is achieved by means of. a second sensing switch 48 (not shown) in series with the switches 65 and 67.

Abstract: 1476757 Stamping THEODOR GRABENER MASCHINENFABRIK 12 Sept 1974 [18 Sept 1973] 39863/74 Heading B3Q Coining press comprises means for feeding blanks to, and removing coins from, a ring die via a table, a male coining die and an ejector/die with upward and downward working strokes respectively and a drive to the male coining die which includes a transmission element the down stroke of which aligns the coining surface of the die with the upper surface of the table, the feed and removing means being arranged to operate only when the die surface is so aligned. As shown a toggle drive 5 acts on a male coining die 24 via a transmission assembly 20, Fig. 4. When the press is at rest there is a gap 16b between upper members 17-19 of the assembly, which rest on a damping ring 21b in a recess 21a of the press frame, and a lower push rod 16. A pneumatic device 45 acts via a lever 42 and rod 40 on the ejector/die 28. The die 28 is mounted on a holder 30 providing fine angular adjustment of the die. The upward stroke of the holder is limited by a strop 32 adjustably mounted on a fixed yoke 33 by a worm (34), Fig. 2 (not shown). The downward stroke is limited by an adjustable screw 46. A fixed ring die 25 is mounted above the press table 22 at a height slightly greater than the thickness of a coin blank. Blanks are delivered to one of a multiplicity of recesses (52), Fig. 3 (not shown), of a rotary table 51 from a stack 54. In operation, the first position of the upward, coining stroke of the toggle 5 closes the gap 16b. Then the die 24 is raised, lifting the blank and the ejector/die against the pressure of the device 45 until the holder 30 abuts the stop 32 when coining takes place. The push rod 16 is immediately lowered, thus lowering the die 24 until the plate 17a abuts the damping ring 21b at which point the upper face of the die 24 is fluah with the top of the table 22. The ejector/ die follows, disengaging the coined blank from the ring die and returning it to rest on the male die in its recess in the table 51. A discharge shoot (not shown) is located at one indexing position of a recess 52.

Title: Improvements in or relating to side channel pumps
IPC: F04D5/00
Filed: 1963-10-14
Abstract: 995,983. Centrifugal pumps. SIEMEN & HINSCH. Oct. 14, 1963 [Oct. 16, 1962; Sept 3, 1963], No. 40361/63. Heading F1C. In a side channel pump having control discs disposed laterally of the impeller and formed near the impeller vanes with ports for the conveyed medium, a side channel for liquid delivery, an auxiliary channel and a gas exit port, those boundary edges of the ports and/or side channel or auxiliary channel which lie in the main planes of the control discs within the radial extent of the vanes, lie at angles of from about 30 to 150 degrees to the front side edges of the vanes. The main planes are those planes of the control discs which are immediately adjacent the impeller. By so arranging the boundary edges relative to the impeller vanes, noise, created by periodic interruption of liquid flows passing over edges otherwise parallel to the front side edges of the vanes, is reduced. One of the control discs of the pump is provided with a side channel 18, Fig. 6, of semi-circular cross-section, in which disc the start 20 of the side channel 18, the finish 22 of the auxiliary channel 21, and the finish or the start and finish, of the liquid port 19 are arranged radially outside the zone (7 to 8) of the vanes. This is because they all contain boundary edge parts with angles outside the range stated. For the same reason the start and finish of the gas outlet 23 are raised clear of the main plane of the control disc to form pockets on the side of the control disc remote from the impeller, which side is provided with a baffle 26 extending transversely to the flow. Alternatively, the start and finish of the gas outlet may be arranged radially outside the zone of the vanes. In a cylindrical section, Fig. 7, through the side channel 18, the angles #1 and γ1 that the start of the side channel and the finish of the auxiliary channel make with the main plane of the control disc are # 30 degrees. An inlet port provided in the control disc on the other side of the impeller may have its start and finish either raised out of the associated main plane or arranged outside the radial extent of the vanes.
