Class 100(2) A mounting for a silk-screen frame moved to successive positions along a table for printing textiles comprises an elongated angle iron having wheels running on rails at one side of the table, and a bar for attachment to the frame at one side thereof and on the outside thereof so that the frame may be raised and supported manually at its other end and be wheeled from one position to another, the bar being adjustable horizontally and vertically relatively to the angle iron and having a limited angular adjustment in the horizontal plane relatively to the frame. A wheeled assembly B is arranged to run on a rail 3 by means of wheels 2 carried on extensions of an angle iron 1 carrying blocks 13. Adjustably secured in and through the blocks 13 bv screws 14 are rods 12. having handle portions 12A for lifting the assembly bodily and carrying posts 9 in slots 11 of which are located bolts 10 for adiustablv securing brackets 8 carrying a bar 4 provided with bolts 5. The screen frame A carries plates 6 with slots to engage the bolts 5. being clamped by nuts 7. The frame has handles 15 by which one end can be manually raised and supported while it is wheeled over the rail 3 to the next printing position. At each printing position. the rail 3 carries a block 25 having a slot 27 to engage a pin 19 carried on a lever 16 pivoted at 17 to a bracket on the angle iron 1 and urged downwards by a spring 20. The pin 19 can be released from the slot 27 by a handle 24 and Bowden cable 23. According to the Provisional Specification, two downwardly divergent squeegees are located on opposite sides of a mounting provided with two parallel upwardly curved tubular handles, and at each end of the mounting is a longitudinally extending leaf spring carrying at its outer end a projecting rigid plate, which rests on the side members of the frame to provide a resilient support when the squeegee device is at rest and is pivoted clear of the frame when each squeegee is brought into use. A bolt threaded into a fixed nut at each end of the mounting engages the spring to adjust the tension thereof.
