ABSTRACT:
A button selector feed for button sewing machines which has a button clamp plate with a button feed slot through which a driver is movable to advance a button into association with the sewing apparatus, comprises a button selector which is mounted on the clamp plate adjacent the feed slot. The button selector has a fixed part with a button delivery slot overlying the feed slot and a movable part which is movable relative to the feed part and which contains a plurality of button feed channels defined therein, each accommodating a stack or a supply of a button of a particular type. The movable part is movable, for example, rotatable, relative to the fixed part so as to position a selected one of the feed channels into alignment with the feed slot. The button feeding mechanism includes means for holding a button in a feed slot after it has been withdrawn from the button delivery slot until a driver which is mounted on a lever for movement therewith engages the button and advances it into association with the sewing needle.
