    摘要: Metal castings are prepared using rigid closed molds by submerging the mold in a bath of lower temperature molten metal, with removal of the mold from the bath being handled to hold the metal inside the mold, but to allow the excess metal to run off the exterior of the mold without metal freezing thereto which could cause damage or locking-in of the mold.

    摘要: Metal castings are prepared using thin rigid closed molds by submerging the mold in a bath of high temperature molten metal, with removal of the mold from the bath being handled to hold the metal inside the mold, but to allow the excess metal to run off the exterior of the mold without metal freezing there which could cause damage or locking-in of the mold.

    摘要: An insert for a railroad brake shoe having a support plate engageable complementally with a portion of the shoe back. Shoulders are provided for preventing the lateral and longitudinal displacement of the insert relative to the brake head assembly. A guide is cantilevered from one side of the support plate and so configured to generally complementally fit the flange of the wheel, thereby to guide the shoe into aligned contact with the wheel tread when the brake is applied.
