A railway car connection system for a railway car having a center sill. Such connection system includes a sliding yoke. The sliding yoke having a front pocket portion open at a front end thereof. The front pocket portion is formed by a top wall portion, a bottom wall portion and a pair of radially opposed side wall portions which form a continuous outer wall. Such continuous outer wall has an outer cross section complementary to an interior cross section of such center sill and capable of both being received therein and sliding longitudinally thereof. The top wall portion has a first bore therethrough and the bottom wall portion has a second bore therethrough concentric with such first bore. A rear block portion having a top wall portion, a bottom wall portion and side wall portions each adjacent the corresponding top wall portion, bottom wall portion and side wall portions of such front pocket portion. At least the side wall portions of such rear block portion being recessed inwardly toward a longitudinal center line of the sliding yoke from corresponding adjacent portions of such continuous outer wall of the front pocket portion. Such rear block portion has a rear wall surface provided with a bore having its axis along the longitudinal centerline of the front pocket portion. Such bore extending through the rear wall surface of such rear block portion and at least partly through such rear block portion.

The present invention provides a castable pedestal-type support apparatus for a cargo shipping container. Such support apparatus includes a body member having a pair of side wall portions and a connecting wall portion disposed midway between the side wall portions. A generally rectangular end wall portion is disposed at a first end of the side wall portions. At least one aperture is formed through the end wall portion. A pivot pin receiving portion having an aperture formed therethrough is disposed intermediate the side wall portions closely adjacent a second end thereof. A counterweight is disposed intermediate the pair of side wall portions to provide a predetermined force required to pivot the support apparatus.

A system for manufacturing a wheel includes a cope mold portion with internal cope mold walls and a drag mold portion with internal drag mold walls. The internal cope mold walls and internal drag mold walls define at least in part perimeter boundaries of a wheel cavity. The wheel cavity includes a cavity center portion configured to form a wheel center portion of a wheel after solidification of a molten alloy in the cavity center portion, a cavity plate portion configured to form a wheel plate portion of the wheel after solidification of a molten alloy in the cavity plate portion, and a cavity flange portion configured to form a wheel flange portion of the wheel after solidification of a molten alloy in the cavity flange portion. The system includes a chill component positioned within the wheel cavity adjacent the cavity flange portion. The chill component is configured to provide directional solidification from the cavity flange portion toward the cavity plate portion of molten alloy in the wheel cavity.

A drawbar for a slackless drawbar system comprises an elongated bar having a load support portion adjacent its one end for connection to one of a pair of adjacent cars in a train, a pin receiving opening extending through the load support portion, a hemispherical recess extending partially around the pin receiving opening and a pin bearing having a hemispherical outer surface receivable in the hemispherical recess and a cylindrical inner surface to receive a pin. The pin bearing preferably is constructed of two symmetrical halves retained in the hemispherical recess by a retaining clip of spring material and the pin receiving opening is provided with a recess to receive the pin bearing retaining clip. The drawbar is provided with a second load support portion at its other end which may be the same as the load support portion at its one end or which may be different if required to connect to a railway car with a different form of coupling.

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.

The present invention provides a weldable cast insert that enables a particular style locking mechanism to be used in securing a container to a support pedestal on a transportation vehicle. Such cast insert includes a plate-like portion having at least one lug-like portion extending outwardly from an outer edge of the plate-like portion and at least one leg-like portion which depends from a first surface of the plate-like portion at least one aperture having a predetermined configuration is formed through a predetermined portion of the plate-like portion and at least one cut-out portion and such at least one leg portion adjacent a predetermined surface thereof.

An adjustable securing device for securing spaced wedge members to provide for movement of the wedges together or apart comprises a threaded bore in one wedge that has threads opposite in direction from a threaded bore in the second wedge. A threaded member has threaded portions engageable with the threaded bores of the wedge members and upon engagement therewith, rotation of the threaded member in one direction moves the wedges apart while rotation in the other direction moves the wedges together. The wedge members preferably have tongues which fit complementary members, such as flanges, on blocks so that engagement of the wedge members with the blocks and movement of the wedges together or apart will either push the blocks apart or pull the blocks together.

The present invention provides a castable pedestal-type support apparatus which supports a cargo shipping container on a transportation vehicle in a position to be secured thereto by a particular style locking mechanism. Such apparatus includes a body portion with a pivot pin receiving portion extending outwardly from a portion of an outer surface of each of a pair of side wall portions of such body portion. An aperture is formed through the pivot pin receiving portion. The apparatus further includes a box-like member formed at one end of the body portion to receive a locking mechanism therein. There is a counterweight disposed at the other end of the body portion to provide a minimal force being required to pivot the apparatus from an inoperative container supporting position into an operative container supporting position.
