| 145 | SUBSURFACE CHILLS TO IMPROVE RAILCAR KNUCKLE FORMATION | US15069576 | 2016-03-14 | US20160193654A1 | 2016-07-07 | Jerry R. Smerecky; F. Andrew Nibouar; Noland Brooks; Nick Salamasick |
| A method for manufacturing a railcar coupler knuckle includes, before casting, positioning an external chill within a cope mold portion and a drag mold portion offset from and adjacent internal walls of a pulling face and a throat of the cope and drag mold portions, thus producing a casting with reduced micro-shrinkage in at least the throat, a high-stress section of the casting. Use of subsurface chills produces an improved surface with fewer inclusions when compared to an equivalent surface produced in a process without use of a subsurface chill. The external chill may be a cone chill of a larger size to improve cooling and solidification at and below the surface. The external chill may also be a cylindrical and/or oblong chill with a tapered design that may correspond to the internal walls of the cope and drag mold portions between the pulling face and the throat. | ||||||

A through hole is formed in the top seat (7), the eyelet bolt (6) penetrates through the through hole in the top seat, a nut (9) is fixedly arranged at the tail end of the eyelet bolt (6), a spring (10) is arranged between the nut (9) and the through hole of the top seat (7), and the diameter of the spring (10) is larger than the diameter of the through hole in the top seat (7). The balancing apparatus can effectively prevent the phenomenon of a “bent head” found in a transition coupler when coupling car-couplers, and the transition coupler can be horizontal after being installed. | ||||||

A locking mechanism comprises protrusions (6) distributed at the other end of the compression rod (2), and grooves (7) in engagement with protrusions (6) on the inner wall of the bearing connector (3). One end of the compression rod (2) is connected to the movable housing (1) via a torsion spring (5), keeping the compression rod (2) and the bearing connector (3) in a locked state; an unlocking driving mechanism is provided on the outside of the movable housing (1), and is in an unlocked state when the protrusions (6) face the grooves (7), in which case, the movable housing (1) and the bearing connector (3) can slide relative to each other. Since the extension/retraction driving mechanism (9) is provided inside the movable housing (1), volume is reduced, good protection is provided for respective components, and the telescopic mechanism and the locking mechanism are relatively simple in structure, labor-saving, reliable in operation, and can bear relatively large loads. | ||||||

| An improved coupler-knuckle assembly is comprised of a coupler body, a knuckle, and at least two knuckle retainer plugs. The knuckle has an internal coring geometry that increases the cross-sectional area of the throat portion of the knuckle compared to previous designs. The present invention's knuckle design includes a top and a bottom tapered holes in the knuckle with a locking groove at the bottom of each tapered hole for the knuckle retainer plugs to snap into. The knuckle retainer plugs are inserted through the coupler body and into the tapered holes in the knuckle. The improved coupler-knuckle assembly of the present invention reduces fatigue on the coupler, knuckle, and knuckle pin, prevents misalignment of the coupler-knuckle assembly, and prevents knuckle pin breakage. | ||||||

| A semi-automatic method for reconditioning an articulated connector while it is still mounted to the end structure of a rail car is disclosed. The female connector is mounted to a fixture and subsequently appropriately aligned. Weld metal is automatically applied to the worn portion of the female connector while attached to the aligned fixture.

| A muff coupling intended for vehicle couplers includes two components formed with ring-shaped flanges, as well as a muff consisting of at least two arch parts tightenable against each other, each having an inner flute formed between two inwardly turned bulges, which flute is delimited by obliquely inclined side surfaces to, upon radial tightening of the arch parts against each other, be pressed against analogously obliquely inclined shoulder surfaces on the flanges and thereby, by wedge action, transfer axial component forces to the same, pressing the ends of the components in close contact against each other. The arch parts are formed with double sets of bulges for cooperation with double flanges on the respective component, whereby forces that are transferred between the components via the muff are distributed to a plurality of axially spaced-apart pairs of contact surfaces in an axial train of forces near the outside of the components. | ||||||
