Abstract

216,904. Thompson, W. P., (Union Special Machine Co.). Dec. 6, 1922. Sewing-machines; duplex feed by dogs.-The main feed-dog is carried by an upright bar 5, Fig. 1, pivoted to a lever 8 to receive vertical movements and connected by a link 13 to an eccentric rod 10 which is restrained by an oblique anchor link 11 so as to cause it to impart to- and-fro movements to the feed-bar. The auxiliary feed-dog is carried by a bar 15 pivoted at 16 to the main feed-bar 5.and is slotted at 18 to engage a block 19 carried by a pin 20 adiustablv fixed in the machine frame. The main feed is varied by means of a normally stationary part 12 to which the anchor link 11 is pivoted. In a modification, the auxiliary feed-bar has an adjustable pin-and-slot connection with a lever 26, Fig. 4, pivoted at 25 to the machine frame. A second arm of the lever 26 has a sliding-rocking connection 28 with the lever 10.
