130,478. Thompson, W. P., (Union Special Machine Co.). Aug. 9, 1918. Sewing-machines; foldding-devices.-A folding attachment made in two parts, separable at the will of the operator without stopping the stitching mechanism, in order to facilitate hemming tubular garments, is mounted on the work support so as to swing forwardly from the stitch-forming mechanism. The outer folding member 22 is adjustably fixed on a plate 14 and the inner folding member 21 is slidable in guides on the said plate 14, and is held close to the outer member by a spring-pressed rod 33. which co-acts with a projection on a lever 37 connected to a. treadle or knee-lever by means of which the two parts of the folder may be separated when the hem of a circular garment is nearly completed so as to allow the stitched hem to pass up to the needle. The front end of the folder has a guard lip 8<a> extending laterally across the meeting edges of the sections The device is carried on a brachet 13 pivoted on a clamp 9 for attachment to the frame of the machin. A spring 18, in co-operation with a cam surface, holds the device in or out of working position as required.
