Abstract: <PICT:0602262/IV (c)/1> <PICT:0602262/IV (c)/2> An apparatus for setting and shaping stockings and other fabrics comprises a retort 30 having a rectangular opening 30a normally closed by a hinged door 33, a main carriage 35 movable outside of said retort transversely to said opening upon a pair of parallel main tracks 34, a form carriage 37 mounted on said main carriage for movement transversely to the path of movement of said main carriage upon a pair of track members 36 which extend parallel to the axis of the longitudinal retort, locking bars 100 which are adapted to position the main carriage 35 so that the form carriage 37 may be moved therefrom into the retort, power-actuated means for moving the aligning form carriage into and out of said retort after the movement of said carriage has been manually initiated, means for permitting said form carriage to be tilted to an inclined position when it is withdrawn from said retort, means for latching said form carriage in said inclined position, means actuated by the tilting of said form carriage for releasing said main carriage and allowing movement thereof to move said form carriage out of alignment with said opening, and means actuated by a return movement of said main carriage to the extent required to position said form carriage again in <PICT:0602262/IV (c)/3> alignment with said opening for releasing said form carriage from said latching means.  The form carriage carries trunnions 135 which are engaged by the hook bearing members after a predetermined travel of said carriage on said track members which enable the form carriage to be tilted about the axis of said trunnions.  The form carriage which travels forward on the track members 36 to the auxiliary track members 44 mounted parallel to but at a higher elevation than said track members and terminate at their outer ends in upturned hook bearing members is tilted into an inclined position by means actuated by its own momentum in which position it is automatically latched. The tilting of the form carriage actuates means by which the main carriage is released, allowing the movement thereof.  Movement of the main carriage actuates means by which the latching of the form carriage is released.  The means for opening and closing the door 33, moving the form carriage into and out of the retort, admitting high pressure steam to the retort, withdrawing the carriage from the retort, shutting off the steam and exhausting the retort are all power actuated with additional automatic means for controlling the sequence and time durations of said steps.  The apparatus also comprises means for conveying steam to and from said retort, fluid pressure-operated means for operating the door, moving the form carriage and controlling the flow of steam in said conveying means, solenoid-operated valves for controlling said fluid pressure-operated means, an electric circuit having a number of branch circuits connected to said solenoid-operated valves, a motor-driven rotary controller comprising a number of switches connected in said branch circuits for operating said solenoid-operated valves in predetermined sequence and time relation and means actuated by the movement of said carriage for starting the operation of said motor, said controller having means for thereafter continuing the operation of said motor through a predetermined cycle of operations of said solenoid-operated valves, means for actuating mechanism including a latch member movable parallel to the path of movement of the form carriage, means for automatically causing said latch member to seize said carriage when said carriage is moved into proximity with said latch member, means for then operating said mechanism to move said carriage into said retort and subsequently reversing the direction of movement of said carriage, means actuated as said carriage passes outwardly through said opening for operating said latch member to release said carriage and resilient means adapted to cushion the movement of said carriage as said carriage approaches said latch member and to project said carriage from said retort when said carriage is released by said latch member.
