Claims

[Scope of utility model registration request]

The chamber shaft, which is rotatably driven by the drive motor, is vertically supported in the upright part of the sewing machine frame, and the vertical feed cam, which has a vertical cam lift, and the horizontal feed cam, which is an eccentric circular cam, are supported together or separately. The feed shafts 1 or 2 to which the drive pulley is fixed and the hook drive shaft to which the hook device is attached and the hook shaft drive pulley are fixed are attached to the auxiliary machine frame fixed in the sewing machine frame bed section, respectively. A belt is stretched between each of the pulleys so that they rotate in conjunction with each other, and a belt is stretched between one of the pulleys and a pulley attached to the chamber shaft. In addition to transmitting power from the chamber shaft, a cam follower is provided protruding from a rocking body that is equipped with a feed dog at one end and supported at the other end by the auxiliary machine frame so as to be able to swing back and forth and up and down. , the swinging body is caused to swing up and down by the rotation of the vertical feed cam, and a sliding body is attached to an end of a rod surrounding the horizontal feed cam,
The sliding body is slidably fitted into a retaining groove of a feed adjuster whose inclination direction can be adjusted, and the sliding body and the oscillating body are connected by a link, and the oscillating body is moved by rotation of the horizontal feed cam. Sewing machine feeder 1 characterized by swinging back and forth
