A button attaching machine having an apparatus for preventing button parts from falling from an intermediate chute when the latter is detached from a chute assembly. The apparatus includes a transverse lever pivotally connected at one end to a bracket mounted on a lower end of the intermediate chute, and a blocking member carried on the lever remotely from the bracket and having a first and a second projection. The lever is normally urged by a spring to turn so as to cause the first projection to penetrate into a channel of the chute, thus blocking the passage of the button parts. When the chute is mounted, the second projection is pushed by a stop until the first projection is retracted from the channel of the chute, thus allowing the passage of the button parts. |
