Abstract

881,623. Sewing machines. PFAFF A. G., G. M. Aug. 18, 1958 [Aug. 24, 1957], No. 26426/58. Class 112 [Also in Group XXV] A sewing machine presser foot assembly comprises a member adapted to be mounted on a sewing machine presser bar and provided with a cylindrical guide slot, a guide member carried by a shank of a presser foot and adapted to be slidably inserted in the guide slot, rotation of the guide member being prevented by the shank and the depth of insertion of the guide member being limited by an abutment, and latch means adapted to retain the guide member releasably in the guide slot. In Figs 1 and 5 a presser foot 18 has a shank 17 formed at its upper end with a cylindrical portion 19 adapted to slide into a cylindrical bore 4 formed in a member 3 secured to the presser bar 1, the shank 17 passing through a slot in member 3. A cylindrical bore 5 formed transversely to bore 4, and intersecting the latter, journals a cylindrical latch member formed centrally with a latch portion 8. A leaf spring 11 acts on a handle 9 rigid with the latch member to bias the latter anti-clockwise. The front end of portion 19 first engages the flat bottom surface 24 of portion 8 to turn the latch member clockwise until the rounded front end of portion 8 engages the forward face of a transverse notch 23 in portion 19, and by cam action on said face under the bias of spring 11 moves portion 19 until a collar 21 thereon abuts a countersunk portion 22 of bore 4. The latch member may be turned by handle 9 for releasing portion 19. In a modification, Fig. 9, a member 103 secured to the presser bar 1 has a cylindrical bore 104 extending diametrically into upper and lower slots 106. The presser foot shank 117 is formed with a cylindrical portion 119 which is slidable in base 104. A transverse notch 123 in portion 119 is engaged by one arm of a lever 108 which is pivoted at 107 in the upper slot 106 and the other arm of which constitutes a handle 109. The nose 112 of a leaf spring 115 acts on the lever 108 to bias portion 119 inwardly until a shoulder 121 on shank 117 abuts wall 122 of member 103.
