Claims

[Scope of utility model registration request]

(1) In a sewing machine feed device in which the feed amount is adjusted by changing the inclination of the tension box, the brake body 12 and the drive are fixed to a rotating shaft 8 to which the tension box 7 is attached in the center. The cam part 13 formed on the shaft 9 is provided between the shaft 9 and the cam part 13 formed on the shaft 9, and is actuated by the cam part of the rotating drive shaft to press the brake body 12 and rotate the feed dog while the feed dog is raised and at least the cloth is being fed. A feeding device having a holding device A that holds the shaft in a fixed state.

(2) The holding device A consists of a bracket 11 into which the drive shaft 9 and the rotating shaft 8 are loosely fitted, and a lever 15 whose intermediate portion is pivotally supported by the bracket 11 and whose one end is engaged with the cam portion. The lever is pivoted by a cam part and the other end of the lever is rotated by the brake body 1.
2. A feeding device according to claim 1, wherein the feeding device is adapted to crimp two parts.

(3) The feeding device according to claim 2, wherein a brake piece 14 is attached to the other end of the lever.

(4) Screws 16, 17, and 22 that move forward and backward in the radial direction of the corresponding drive shaft or rotating shaft are screwed onto at least one end of both ends of the lever, and the forward and backward movement of the screw is adjusted. 3. The feeding device according to claim 2, wherein the gap between the drive shaft and the brake cylinder is adjusted by adjusting the distance between the drive shaft and the brake cylinder.

(5) The feeding device according to claim 2, wherein two grooves into which the drive shaft and rotation shaft fit are formed on one side of the bracket.

(6) The feeding device according to claim 1, wherein the holding device A is formed by bending and folding the spring plate 25 and attaching its base to the sewing machine frame 1.
