Title: Improvements in door operating apparatus
IPC: E05F15/02
Filed: 1936-11-05
Abstract: 471,705. Door operating appliances. NATIONAL PNEUMATIC CO. Nov. 5, 1936, No. 30148. Convention date, Aug. 5. [Class 65 (i)] A pneumatic engine for operating a sliding door, particularly of a vehicle, is so connected to the door as to be brought into operation by a slight manual opening movement of the door ; the engine may be reversed automatically at the fully-open position of the door and is also reversed automatically if th closing of the door is obstructed. The engine comprises a fixed cylinder 6 with a piston 26 fixed to a piston rod 11 which has secured to it an abutment 13 engaging a bracket 14 fixed to the door ; the bracket 14 is normally held against the abutment 13 by a spring 16 on the piston rod. The door bracket 14 also carries a stop 17 engaging the end of a fluted rod 19 which is slidable in an axial bore in the piston rod and which carries a valve and valveoperating member 31. An airtight disc 28 is secured to the piston 26 by a ring 30, with an interrupted flanged end which limits the motion of the member 31, and to the piston rod 11 by a ring 29, which forms a seating for a valve disc 34 carried by the member 31 ; the member 31 has a cylindrical wall pierced at 31<1> and is formed with extensions 32 passing with clearance through holes in the disc 28 to engage a valve member 35 which is pressed against the disc 28 by a spring 36 to cover the openings through which the parts 32 pass. Compressed air is supplied continuously through a passage 24 to act on the right-hand side of the piston, and in the position shown it is shut off from the left-hand side by valve 35, while the left-hand side is opened to atmosphere through valve 34 and the flutings of the rod 19 so that the piston is moved to the left and the door opens. When the door is fully open, the member 31 strikes a stop 40 (which can be turned out of the way if the door is required to remain open) and is moved to the right, closing valve 34 and opening valve 35, so that compressed air can pass from the right-hand side of the piston through passage 27, valve 35, the passages in disc 28 and openings 31<1> to the left-hand side, where it acts on a greater area of the piston and consequently forces the piston back to the right to close the door, the spring 16 being sufficiently strong to carry the normal closing load. If the closing of the door is obstructed, the spring 16 is compressed and the piston rod 11 slides through the door bracket 14 until the rod 19 strikes the stop 17 on the door bracket and is forced inwards to move the valves to the door-opening position. When the door is fully closed, the valves are similarly set to the opening position shown by slight manual movement of the door relative to the piston rod 11 to operate the rod 19 by means of the stop 17 ; the spring 16 is compressed until the engine takes up the load.

Abstract: 1,248,411. Riveting. GEORGE TUCKER EYELET CO. Ltd. 25 June, 1969 [26 June, 1968], No. 30358/68. Heading B3U.  A blind riveting machine comprises a reciprocable setting head 47 and a transfer device 128 which is reciprocable and rotatable about a horizontal axis for picking up fasteners from the lower end of a raceway 82 and presenting them reoriented about the horizontal axis to the fastener-setting head 47. Blind rivet assemblies 14 are fed from a vibratory hopper 30 down the raceway 82, the lowermost assembly 14 being arrested by abutments 102 (104) of the raceway 82. The transfer device 128 includes a sleeve 126 which is moved to the left as the head 47 is retracted by a connecting link 74. Mounted within the sleeve 126 is a rod 152 having a magnet 176 at one end for engaging the mandrel stem. As the sleeve 126 is advanced, the lowermost rivet assembly 14 is removed from the raceway 82 by the rod 152 which is thereafter also rotated by a stud 156 engaging in a part spiral groove 154 in the rod 152 to cause the assembly 14 to be turned over and positioned beneath the head 47. The next assembly 14 in the raceway 82 is held back by the advancing rod 152. The cycle of operations is initiated by the workpieces 10, 12 to be riveted actuating a valve (232) (Fig. 12, not shown), which actuates a cylinder 50 controlling the reciprocation of the setting head 47. As the head 47 advances, the mandrel stem is engaged by the nosepiece 190 of the head 47 and the rivet assembly is pulled off the magnet 176, the assembly being prevented from falling by a portion 220 attached to the rod 152. The rod 152 of the transfer device 128 is retracted and rotated as the head 47 is advanced so that the portion 220 is removed from the path of the nosepiece 190 to allow it to position the rivet in the workpieces 10, 12. A valve 68 is actuated by the head 47 to cause a cylinder (196) to be actuated which operates a mandrel pulling device within the head 47. A valve 244 is also actuated by linkage 240, 250, 254 causing the cylinder 50 to retract the head 47 after the mandrel stem has been broken and the rivet set. A spring detent (218) (Fig. 10, not shown) is positioned within the nosepiece 190 for engaging the mandrel stem. Suction means may be provided on the rod 152 if the mandrel is non-ferrous. The setting head 47 is mounted in a guideway 42 which is adjustable about an axis 38.
