ABSTRACT:
A pneumatically operated pile carpet trimmer includes a housing having a drive shaft projecting from one end thereof, and a shearing head removably threaded on the last-named end to surround the projecting end of the shaft. An operating lever which is pivotally mounted in the head is connected at one end to the movable shearing member of a set of shears which is removably mounted on the bottom of the head, and the opposite end of the lever is releasably connected to an eccentric carried by the drive shaft. When the latter rotates it oscillates the lever, which therefore reciprocates the movable shearing member. The head may have two sets of shears removably mounted thereon to operate in intersecting planes. In each case exhaust air from the housing is directed onto the shears to blow away cuttings.
