Abstract: 366,672. Ironing - presses. PROSPERITY CO., Inc., Lombard Street, Syracuse, New York, U.S.A.-(Assignees of Davis, E. ; 404, Ellis Street, Syracuse, New York, U.S.A.) Dec. 30, 1930, No. 39210. Convention date, May 22. [Class 138 (ii).] An ironing press comprises an adjustably mounted fixed press head 10, Fig. 2, and a number of bucks 17, 18 having downwardly projecting pins 19 slidably mounted in a frame 16 that can be oscillated through 180‹ by power about one of the pillars 14 that support the head. Oscillation of the frame is effected by the engagement of a pinion 21 thereon and a rack 22 which is reciprocated by a piston 25, Fig. 6, working in a cylinder 26. The buck which has been swung to position beneath the head is raised into pressing- engagement therewith by another piston and cylinder mechanism 40,41. The control means for the fluid pressure operating the pistons 25, 40 are arranged so that upward movement of a buck is prevented except when such buck is positioned beneath the press head and so that rotation of the frame is prevented when a buck is in pressing engagement with the head. Actuation of the means for moving a buck into pressing engagement with the head automatically follows the swing- ing of the frame to one or other of its extreme positions. The piston 40 operates an eccentric 33 which acts on a vertically movable member 31 carrying a plate 30 which contacts with the pins depending from that buck which is under the press head. As the member 31 rises, a roller 46 drops into a vertical groove 45 therein to close a valve 64 in the pressure-fluid supply pipe 105 thereby cutting off the supply to the pipe 107 which feeds valves 64a, 64d, in casings 63, 80 which control the admission of fluid pressure to the cylinder 26. Before the piston 40 is actuated, however, the valve 64 is open so that depression of the appropriate button 60, 61 to open the valve 64a or 64d admits fluid pressure to the cylinder 26 through the pipe 108 or 110 respectively. Simultaneous depression of both buttons is rendered non-effective by the opening of exhaust valves contained in casings 90, 92 and arranged, respectively, in the circuits controlled by the opposite valves 64d, 64a and mechanically linked to the buttons 60, 61. Maintaining means 73a, 73d are provided for the valves 64a, 64d. As the piston 25 reaches the end of its stroke the appropriate pawl 53 of a trip rod 50 carried thereby momentarily closes an exhaust valve 65a and opens an inlet valve 64c in a pipe 106a whereby fluid pressure is admitted by pipe 115 to a diaphragm chamber 73b to open and maintain open a valve 64b whereby fluid pressure is admitted to the cylinder 41 through a pipe 116. The buck is then raised into pressing engagement with the head and remains so until the depression of one of the buttons 60, 61 which opens an exhaust valve 82 or 91 respectively thereby exhausting the iiaphragm chamber 73b and closing the valve 64b, simultaneously opening an exhaust valve 65b. After the slot 45 has cleared the roler 46, the appropriate button 60, 61 is operated to admit the fluid pressure to the end of the cylinder 26 opposite to that at which it was admitted previously.
