Abstract

1,051,798. Ratchet gearing. SINGER CO. July 14, 1965 [July 16, 1964], No. 29761/65. Heading F2Q. [Also in Divisions D1 and E2] In a buttonhole sewing machine a sleeve 133 is rotatable on a shaft 91 and is rigid with a ratchet wheel 134. A sleeve 145, axially slidable but non-rotatable on shaft 91, is separated from sleeve 134 by a compression spring 148 and is reciprocated on shaft 91 during operation of the machine by engagement with a member 150 rigid with the needle bar. A plate 153, pivoted at 152 to sleeve 145, carries an upstanding pawl member 154 biased by a spring 156 against ratchet wheel 134. An inclined pawl surface 155 on member 154 serves to rotate ratchet wheel 134 on upward movement of sleeve 145.
