Abstract

729,968. Hinges. UNION SPECIAL MACHINE CO. March 10, 1953 [March 20, 1952], No. 6509/53. Class 65(2). [Also in Group VII] The presser bar 40 of a sewing machine is fixed to a pin 50 slidably and rotatably mounted in spaced bearings 52, 56 in the machine frame 20. A pivoted latch 76 is biased by a spring 82 to engage a groove 80 in the pin for holding the latter in the retracted position against the bias of a spring 62 interposed between the bearing 56 and a collar 58 fixed to the pin. On release of the latch, spring 62 moves the pin outwardly, when a spring-based plunger 64 in collar 58 cooperates with a cam surface 70 on frame 20 to effect simultaneous rotary movement of the pin. Specifications 672,098, [Group VII], and 691,894 are referred to.
