Abstract
An apparatus for protecting a horizontally reciprocable light projector from collision with a vertically reciprocable punch of a button setting machine, wherein a lost motion mechanism is provided for producing a delay between retracting movement of the light projector and the downward movement of the punch to such an extent that the light projector is retracted from the vertical path of movement of the punch before the punch starts moving downward. The lost motion mechanism is composed of a shaft having an annular actuating flange, and a cylinder member slidably receiving therein the shaft. The actuating flange is normally separated from the cylinder member and engageable with the cylinder member to lower the punch when the light projector is retracted from the vertical path of movement of the punch.
