ABSTRACT:
A slackless drawbar system includes a support member comprising a top plate, a bottom plate and a pair of spaced apart side plates joining the top and bottom plates to form a hollow rectangular member closely fitting inside the rectangular longitudinal opening of a railway car center sill. A back wall joins the top and bottom plates and the pair of side plates at a point spaced from one end of the support member and the top and bottom plates are provided with aligned bores each of which has a bushing therein, one of which bushings receives one end of a cylindrical pivot pin and the other of which bushings receives the other end of the pivot pin. The side plates of the support member are secured to the railway car center sill through weld slots in the center sill and at weld chamfers provided at each end of each of the side plates. The support member also includes reinforcing ribs connecting the back wall to the side plates and to the top and bottom plates. A slot is provided in the support member running from the top of the top plate to the bottom of the bottom plate for receiving a follower and slack take-up wedge. A follower support plate and a pivot pin support plate are also provided and are removable secured to the flanges of the railway car center sill.
