Abstract
This invention relates to an apparatus for adjusting the spacing between sheaves and tightening the belts operating the sheaves, the apparatus comprising an elongated threaded rod and an elongated smooth guide rod spaced apart therefrom and parallel thereto, two spaced lateral support arms attached to both rods, one arm being fixed and the other being movable by threaded engagement to the threaded rod, each arm supporting a positionally adjustable concave receptacle, the two receptacles being aligned with each other parallel to the rods and the concave portions facing away from each other, the threaded rod having one end journaled in the fixed arm and the other end fashioned with a head to which a wrench may be fitted for turning the threaded rod.
Claims12
An apparatus for applying force to increase the spacing between two cooperating sheaves comprising an elongated threaded rod having an upper journal section and a lower journal section with a wrench receiving head extending beyond said upper journal section, a stationary transverse support arm having a recess to receive said lower journal section, a travelling transverse support arm having a threaded hole mated with said elongated threaded rod, a nonthreaded guide rod spaced from and positioned parallel to said elongated threaded rod and being affixed to said stationary arm and slidingly engaged in a hole in said travelling arm, a connecting spacer clamped to the end of said nonthreaded rod adjacent the head of said threaded rod and a hole for receiving said upper journal section, each of said arms having adjustably affixed thereto a receptacle adapted to receive a portion of a sheave, the two receptacles being aligned with each other parallel to said threaded arm and directed away from each other.
An apparatus for tightening a belt operating on two cooperating sheaves comprising an elongated threaded rod, an elongated smooth guide rod spaced apart from and parallel to said threaded rod, two spaced support arms substantially perpendicular to said rods and extending outwardly from said threaded rod diametrically opposite to said guide rod, a positionally adjustable concave receptacle adjacent the outer end of each arm aligned with each other in a direction parallel to said threaded rod and oriented with the concave portion of each receptacle facing away from each other, one of said support arms being fixed at the same ends of each respective rods with said threaded rod being rotatably supported therein, and the other of said support arms being movable by threaded engagement with said threaded rod and slidable engagement with said guide rod, said threaded rod having a head adapted to be gripped by a wrench for turning said threaded rod.
