Abstract: 990,674. Textile treating apparatus. TURBO MACHINE CO. March 20,1964 [April 23, 1963, No. 11796/64. Heading D1L. Apparatus for treating textiles comprises a main treatment chamber 10 closed by a door 12 movable bodily outward from the chamber, track means extending along the front of said door including longitudinally spaced stationary loadunload and transfer track sections 30 and 42 respectively on opposite sides of the chamber, and track sections 51 and 63 mounted respectively on the inner and outer sides of said door for movement therewith, the outer movable track section being interposed between and aligned with the stationary track sections, and the inner movable track being adapted for being interposed between and aligned with the stationary tracks when the door is open, means coacting with the door to provide an auxiliary chamber 95 over the outer movable track, carriages 110, 112 and 114 for supporting textile materials to be treated, the carriages being respectively mounted on the stationary load-unload and movable inner and outer tracks, and means for opening and closing the chambers and actuating the carriages in predetermined timed relation whereby each carriage is progressively advanced from the stationary load-unload track to the other tracks and back to the loadunload track for treatment of the textile first in the main chamber and then in the auxiliary chamber. As shown autoclave 10 has a retractable door 12 hung from trolleys 14 movable on tracks 16 by rack and pinion means 22 operated by motor 24. To the left (Fig. 1) of autoclave 10 is a load-unload track 30 and to the right is transfer track 42. The door 12 carries inner track 51 (Fig. 2) and outer track 63. Over track 63 is arranged auxiliary chamber 95 made up of walls 78, 80 and door 12 with side doors 82 suspended from rollers 84 which can travel on inclined bars 86. In wall 78 is a compartment 96 housing a battery of lamps 98 and a blower 99. Mounted on each track 30, 51, 63 is a expansible carriage 110, 112, 114 respectively (Fig. 3) each of articulated cross link construction and mounting a battery of work supporting forms 121. Under conditions shown in Figs. 1 to 3 and 19, carriages 110, 112 and 114 each carry a full battery of forms loaded with stockings. Main treating chamber 10 is closed and the auxiliary chamber 95 is closed. Carriage 110 is expanded for loading and unloading, whilst carriages 112 and 114 are collapsed, carriage 112 being latched against expanding by suitable latch means. The stockings are treated with fluid media in chamber 10 and may be partially dried therein, the drying being completed in chamber 95. The arrangement is such that treatment in chamber 10 of one batch, drying in chamber 95 of another hatch and loading or unloading of another batch on carriage 110 can go on simultaneously. When treatment in chamber 10 and drying in chamber 95 are completed, the door 12 is moved forward to Fig. 20 position carrying with it tracks 51, 63 with carriages 112, 114 thereon and the whole of drying chamber 95. As the door 12 reaches its foremost position it operates a switch to start motor 196 which drives chains 184, 178 and 166. Lug 198 releases switch 200 to open the circuit to lamps 98 and blower 89. Pin 180 on chain 184 engages carriages 112 and moves it to the right on to transfer track 42. At the same time pin 164 on chain 166 engages with carriage 110 to first collapse it into an unexpanded condition and then push it on to the inner track 51. At the end of this movement a switch is operated to stop the motor thus arresting the carriages in the position shown in Fig. 21. Door 12 is then moved back to its closed position and carries with it tracks 51 and 63 with carriages 110 and 114 thereon. It also carries with it the front wall 78 and top wall 80 of chamber 95 but the doors 82 remain in their forward position being held by latch 106 as shown in Fig. 22. As door 12 is closed a switch is operated to start motor 196 whereupon pin 164 moves back to the left engaging carriage 114 and pulling it to the left and expanding it for unloading and re-loading. Pin 190 also moves to the left pushing carriage 112 on to track 63, Fig. 23. In the meantime treatment of the stockings on carriage 110 commences in chamber 10. At the end of the traverse of carriage 112 lug 198 re-emgages switches 200 and 206 to close the circuit to lamps 98 and blower 99 and open the circuit to motor 196. At the same time solenoid 108 is operated to release latch 106 so that doors 82 return to their initial positions. Thus each carriage is advanced progressively from the load-unload track 30, to the inner track 51, to the transfer track 42, to the outer track 63 and finally back to the track 30. Specifications 568, 946, 709, 494 and 954, 441 are referred to.
