Generally, the button feeding machine
is a machine adapted for feeding shank type buttons sequentially into a sewing position. In general, the feed-through mechanism is intended to be relatively simple to maintain and low-cost. Moreover, it is not necessary for the machine operator to align the button holes. The machine can be quickly installed on an existing button sewing machine.
In order to feed the button, the feeding machine comprises a hopper and a chute. The hopper holds the shanks of the buttons, which are then pushed along the chute. The chute is arranged so that the shanks of the buttons are positioned to one side of the chute. The button feeding machine also comprises a presser foot with a channel leading into the chute. The button is moved to the sewing position when the presser foot is lifted.
The shanks of the buttons are arranged to engage the chute contour to extend the shanks to the side of the chute. This does not interfere with the natural gravitational throw of the shanks. However, the engagement of the shanks does not prevent the buttons from backing up. In addition, the shanks are not subjected to sufficient force to sever the thread connecting the buttons to the sewing machine.
The chute is positioned adjacent the discharge opening in the hopper. The ram arm has one end coupled to the oscillatory drive means. The other end is connected to the push arm. The push arm is connected to the base of the button feeding machine. The ram arm has a spring biased finger for engaging the button shank.
