Subsurface chills to improve railcar knuckle formation |

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 boxless casting form which is separated horizontally and which is composed of a lower casting body (1)and an upper casting body (2). The casting bodies (1, 2) are formed of dry sand and define a casting cavity (9). Openings (3, 4) are introduced into the casting bodies (1, 2), and these openings (3, 4) are used to align the casting bodies horizontally and form a vertical guide passage for a rod-like guide element (5). |

A flask for containing mold sand within it prevents any mold shifting or mold dropping. Each of an upper flask 2 and a lower flask 3 includes a body that defines an opening in which a sand mold is to be molded. The body has at least one inlet 101 for introducing the mold sand into the opening. Two flanges 102 are extended from the body such that they are opposed to each other across the opening. Each flange has a through bore. The flask also includes engaging members for engaging an actuator in the outside of the flask such that a force or forces from said actuator could be transmitted to the flask. An upper flask 104 and a lower flask 105 are opposed to each other across a pattern plate 107. They are integrally assembled to make a flask unit by means of a pair of connecting rods 106 that are fitted in each bore. |

William A. Hunter |
The pattern plate of a matchplate molding machine is attached to a drag flask by spring-loaded clamps which may be rapidly opened to enable the plate to be quickly and easily removed from the flask and replaced by another plate. Locating members are attached to the flask in laterally opposed relation with the clamps and coact with the clamps to fixture the pattern plate accurately on the flask. A removable operating handle is provided for opening the clamps and carries a latch for releasably holding the clamps in their open positions during changing of the pattern plates. |

A first insert is arranged to be engaged with one surface of a matchboard in alignment with a bore in the matchboard. A second insert has a portion thereof arranged to be engaged with the opposite surface of the matchboard at the bore. The first and second inserts have impression forming portions arranged to make recess and projecting contours respectively in impression material with a close tolerance interfitting engagement when in facing relation to provide anti-shifting connection to opposed portions of the impression material. The inserts have a telescoping engagement which precisely aligns the first and second inserts in their impression forming functions, and such telescoping arrangement provides adjustable mounting of the inserts on matchboards of different thicknesses. |

Core and shell shooter |

A core or shell blow (shoot) machine, equipped with a quick core-box change device, makes it possible to carry out a quick core-box change in just a few minutes, thereby reducing down time. For this purpose, the core-box change device consists of a twin carrier which is swung hydraulically in a horizontal plane about a vertical axis. The care-box in the machine, after picking up the cope and the cope ejector plate, is lowered by the lift table into the carrier, after hydraulic clamps between the table and the core-box bolster have been released. The core-box change device is then rotated 180.degree., which swings the old core-box out of the machine and, simultaneously, swings the new core-box stack-up into the machine over the lift table. In the meantime, the old blow-plate is removed from the sand magazine, outside of the machine, using the blow-plate removal device. This layout also allows collection of the remaining sand from the sand magazine in a collecting pan, which is part of the blow-plate removal device, insuring a clean, trouble-free core-box change. |
