Abstract: 808,460. Shearing, punching. WEAN EQUIPMENT CORPORATION. March 4, 1957 [March 14, 1956], No. 7067/57. Class 83 (4). In order to accurately locate a continuously advancing strip being cut into sheets by flying shears, a locating hole is formed on the feed side of the blades as the blades make each cut, and a locating means moving with and connected to the shears enters the hole to position the leading end of the strip as each cut is made. The blades 3, 4 are shaped to make an irregular cut as shown in Fig. 6 to form sheets shaped to minimize waste when the sheet is subsequently punched to produce circular blanks 8 and the locating holes 10 are punched in portions of the sheet that are waste. The lower blade 4 is supported by links 16 pivoted on a fixed axis 17 and guided at their upper ends 18 in vertical guides in a frame 15 carrying the upper blade 3 and the punches 20. Eccentrics 13, 14 move the frame 15 through a circular path and so effect shearing. Arms 22, 23 connected to the upper and lower blade carriers 47, 48 carry tapered locating pins 26 and co-operating bushes 30 adjustable along the arms. The pins 26 before each cut is made pass through the holes 10 in the strip and into the bushes 30. The strip is fed by rollers 31 which may be driven from the shaft 12 of the eccentric 14, the upper roller being raised by a lever 35 actuated by the blade carrier 47 just after the pins 26 enter the holes 10. The severed sheets are carried away at a higher speed than the feed by three parallel moving belts 45. Strippers may be provided for the punches 20 and locating pins 26.

Filed: 1948-03-12
Abstract: 647,087. Snap-action switches. DEHN, S. G. (Sunbeam Corporation). March 12, 1948, No. 7604. [Class 38(v)] [Also in Groups VI and XI] A switch for a coffee maker (see Group XI), comprises a contact 39 carried by a fixed conductor 41 and cooperating with a contact 38 carried by a flexible conducting member 37. A diaphragm 47, e.g. of a syphon bellows, is exposed on its lower face to the pressure in the lower vessel of the coffee maker, its upper face engaging a latch 45 pivoted at 55 between the arms of a bell-crank 51 pivoted at 52. A spring maintains a projection 54 on the crank 51 in contact with the diaphragm 47. Upon a pressure increase in the vessel, latch 45 is carried up, the crank 51 being rotated anticlockwise, and the contacts 38, 39 remaining closed. Upon a subsequent fall in pressure in the vessel, the member 37 is engaged in a notch 62 in the latch 45 which eventually depresses the member 37 to open the contacts 38, 39. To re-set the switch manually the crank 51 is moved clockwise, which, since the latch 45 engages a fixed stop 57, moves the pivot point 55 to swing the latch 45 anti-clockwise and release the member 37. A bimetallically-operated switch 64, 65 shunts the switch 38, 39. In a modification, Fig. 11 (not shown) the upper contact arm of the switch is retained in its uppermost position after a rise in pressure in the vessel, by friction washers. The lower contact arm follows the diaphragm down in its subsequent fall, to open the switch. Both contact arms can be independently pivoted manually by pressing external buttons to open or close the switch. Specification 625,797 is referred to.

Title: Improvements in or relating to steam separators
IPC: F16T1/24
Filed: 1924-03-25
Abstract: 223,814. Eisenbeiss, E. March 25, 1924. Steam - traps. - A steam separator or steam trap of the kind having a fluid pressure operated and float controlled discharge valve gear is characterized by the combination of the valve gear with a discharging member so displaceably arranged that it is surrounded by steam. When the separator is filling and the! discharge valve is closed but dips into the condensate when the valve is open for discharging. The cylindrical separator a, Fig. 1, has an inlet A and depending inlet tubes B in the upper part of which is a throttle valve C. A float b is pivotally mounted on a shaft c which also carries an arm d connected with rod e of a piston valve which controls a piston f. The piston f operates a hollow shaft i through the lever g. The hollow shaft carries a depending discharge tube h and communicates with a space m, Figs. 2 and 4, leading to the discharge valve which is controlled by the lever k. The valve consists of a fixed rod n, having an axial bore s and transverse bore p, and a sleeve m<1> which is movable on the rod by the lever k. In the positions shown the vessel is full of condensate and the pipe h and discharge valve are set for discharging the contents whilst the throttle C is closed. When the vessel is empty the float falls and operates to close the discharge valve and raise the pipe h which in rising contacts with the lever D and re-opens the throttle C. A counting mechanism may be driven off any suitable moving part. The discharges valve when closed is surrounded by steam only. In a modification, the pipe h is replaced by a vertically sliding pipe on the upper end of which is the actuating piston f. The pipe acts also as a valve and has peripheral openings which register with discharge openings in the enclosing guide member. In a further modification, the separator is divided into two portions, an inlet portion which supplies a float portion, the passage between the two being controlled by a valve carried by the vertically sliding discharges pipe. The connection of the float with the piston valve provides for lost motion during the rising and falling movements. In order to give a sharp control, a tumbler-weight lever may be included in the transmitting levers.
