Title: Improvements in automatic reversing mechanism for door-operating motors
IPC: E05F15/02
Filed: 1921-07-12
Abstract: 184,967. Dehn, F. B., (National Pneumatic Co.). July 12, 1921. Operating doors pneumatically.-A sliding door operated by a pneumatic motor is arranged to operate a trip mechanism should it encounter an obstruction in closing, whereby the motor is reversed to move the door towards the open position without interfering with the position of the normal control valve, and as soon as the obstruction is removed the door continues its closing movement. Means are provided for preventing the actuation of the reversing device when the door closely approaches its completely-closed position. The door 7 is operable by a pneumatic motor 1 and a rocking arm 6, the ends of the cylinder being connected through a main valve 9 which normally controls the pressure supply from a reservoir 16. The door is opened and closed by the attendant, who sets the main control valve 9 with an arrangement of ports to supply pressure fluid to one end of the cylinder, the other end of the cylinder being opened to exhaust, the pressure fluid passing from the supply chamber 16 and through the passages 23 in a reversing valve member 18 slidable in a cylinder 17. The member 18 carries a plunger 19, which normally seats against the opening of the pipe 20 communicating with the left-hand side of the motor cylinder and prevents fluid pressure from being supplied through the pipe 20 to open the door. It is maintained in this position by a spring 26 housed in the other end of the cylinder 17, the action of the spring being assisted by pressure which leaks past the piston member 18. When this end of the cylinder is opened to exhaust by an inward movement of valve 32 against a spring 33, the pressure at the other side of the cylinder moves the piston member 18 to allow pressure fluid to pass through the pipe 25 to the motor cylinder, thus causing an opening movement of the door. This movement of the member 18 puts the other end of the motor cylinder to exhaust, the pipe communicating with a duct 28 opening into the right-hand side of the cylinder 17. The valve 32 is arranged to be unseated when the door encounters an obstruction during its closing movement, except when it is near its closed position. For this purpose, the front edge of the door is provided with a pivotally-mounted shoe 34 which is lifted bv an obstruction to operate through links 35, 39 a lever 40 in contact with the valve spindle 27. When the obstruction is removed and the shoe returns to its lowered position, the spring 33 seats the valve 32 and the plunger 19 is thereafter restored to a position in which it closes the pipe 20, the closing movement of the door being then resumed.

Title: A device for use in gas pruifying plants
IPC: C10K1/28
Filed: 1937-07-07
Abstract: 487,550. Gas - purifier valves. JOHNSSON, I., and ABERG, K. July 7, 1937, No. 18865. Convention date, July 11, 1936. [Class 55 (ii)] Apparatus for controlling the flow of gas through purifier boxes comprises a valve casing divided into upper and lower compartments with the lower divided into four chambers 4 each having a top opening 5 ... 8 and a side opening 9 ... 12, a distributing U-shaped pipe 13 being turnably mounted in the upper compartment with one leg 14 communicating with one chamber constituting an inlet chamber and the other leg 15 witli any of the other chambers. Vertical displacement and rotation of the distributer 13 is effected by means of a shaft 18 secured to leg 14 and passing through a bearing 20 in the casing 15a of the top compartment. The top of shaft 18 is bored and has interior threads adapted to engage with a spindle 25 rotatably mounted within a shaft 22, the lower end of which has a non-circular bore receiving a similarly shaped end of shaft 18. Movement of a hand wheel 26 turns spindle 25 so as to engage and raise shaft 18, thus lifting the distributer above the level of the upstanding edges of the openings into the outlet chambers but not above that of the opening out of the inlet chamber. By means of a hand spike 27 the shaft 22, and with it shaft 18 and the distributer, is then rotated so that leg 15 registers with the appropriate chamber opening and the distributer is then lowered into position. The gas is thus directed from the inlet to one of the outlets and may at a later stage in its travel pass through the upper compartment from one of the remaining outlets to the other.
