<p>A button attaching machine having an apparatus for preventing button parts (B) from falling from an intermediate chute (13) when the latter is detached from a chute assembly (1). The apparatus includes a transverse lever (31) pivotally connected at one end to a bracket (21) mounted on a lower end of the intermediate chute (13), and a blocking member (41) carried on the lever (31) remotely from the bracket (21) and having a first and a second projection (43), (44). The lever (31) is normally urged by a spring (34) to turn so as to cause the first projection (43) to penetrate into a channel (8) of the chute (13), thus blocking the passage of the button parts (B). When the chute (13) is mounted, the second projection (44) is pushed by a stop (12) until the first projection (43) is retracted from the channel (8) of the chute (13), thus allowing the passage of the button parts (B).</p> |
