Abstract: 22,424. Johnson, J. Y., [Philadelphia Textile Machinery Co.]. Oct. 4. Clothes - frames and the like. - In hosierydrying machines of the kind described in Specification 28,961/12, wherein the stockings are mounted on a series of shapes or 'forms' caused by scroll cams to travel through a drying- chamber, the stockings are removed automatically from the forms after drying, by providing devices for grasping the stockings and effecting relative movement between these devices and the forms. The drying - chamber, containing steam - pipes 9 and a fan 5, is situated to the rear of the bed, its upper portion being rounded and its front projecting over the rear edge. Doors 10 are provided at the ends of the chamber, adjacent to which are slots 11, 12 permitting entry and exit of the flat stocking forms. These forms 15, Fig. 4, are borne by carriers 14 moving in guides formed by plates 16. The head 17 of each carrier has a bearing in which is mounted a spindle supporting a bracket 46 having a bearing for the stem of the form. An arm on which rollers 48, 49 are mounted is clamped on the spindle end. The bracket 46 carries a detachable counterweight 50 to balance the form. The end of the stem carries a projection 51 which, by engaging guides at the end of the chamber, holds the form in proper position to pass through the slots 11, 12. The scroll cams which move the carriers are driven through gearing from the shaft driving the fan, a clutch being provided; they are arranged, as shown in Fig. 9, so that the carriers accumulate in the drying-chamber and move more rapidly in the remainder of their travel. A rail 53, Fig. 6, extending along the rear and the delivery end of the bed, supports the roller 48 and prevents the form from tilting laterally; after the form has passed the slot 12, the roller 48 enters a groove in a cam-plate 56, and the form turns to the horizontal position; the roller 49 rests on the upper cam-surface, and the form in its further travel rests on a fixed guide 58. A second cam 59 prevents a too rapid motion of the carrier. After the stocking is removed, the roller 48 engages a rail 60, Fig. 1, and the form is turned by a car 61, Fig. 1, till it is in position to receive a fresh stocking taken from a pile on the table 62. The gripping- devices for removing the stockings are supported through an arm 104, Fig. 12, from a solid shaft 72 enclosed by hollow shafts 70, 71 supported on a frame at the delivery end of the machine, Fig. 1. All three shafts are actuated by rack-and-pinion gear from cams on the front scroll-cam shaft. The shaft 71 is connected by lever arms to a hollow spindle 90 carrying arms 92, 93 on which the grippers are mounted. These arms carry bearings 94, 95, Fig. 13, which themselves carry the fixed parts of the heel and toe clamps. The arm 92 is rigid, but the arm 93 turns in the bearings and actuates the movable portions of the clamps. This arm 93 is turned by a rod 107 actuated through a bellcrank lever and an arm 104 operated by the shaft 72. The movable portion of each clamp may consist, as shown in Fig. 14, of a series of spring-pressed plungers 115, with roughened or ribbed undersides. The bearing 95 slides on the rods and is attached by a cord to a weight pivoted on the rod 92, allowing the toe clamp to assume various positions during the withdrawal of the stocking. When the form leaves the stocking, the clamps open, allowing the stocking to fall on a platform 123, Fig. 1. As the carrier moves on, it engages a lever operating a lazy-tongs and withdraws the platform, the stocking falling on a table 124. The table is adjustably secured to a counterweighted lever 130, Fig. 10, a pin 141 on which rests on a cam so constructed as to be lowered an equal distance as each stocking is placed on the table. When twenty-four have accumulated, the pin falls into a slot 143, the table tilts to discharge the stocking, and a cam 138 on the front scrollcam shaft engages an arm 139, pushing the table back into position. A counting-disk 144 operated from the cam 138 is provided.
