US Patent No. 1,076,798, granted October 28, 1913 to Thomas Thompson of Pawtucket, Rhode Island, for an automatic stopping device for "lever" or "go through" lace looms. The device uses the loom frame as part of an open electric circuit. When a displaced shuttle forces the catch bars out of engagement, spring contacts close the circuit and an electromagnet trips the shipper to move the belt to the loose pulley. A variant breaks the fuses of a motor-driven loom. The scan has four sheets of mechanical drawings (Figs. 1-15) followed by the specification and four claims.
