Abstract: A crowd machinery guard system for a mining shovel is provided. The crowd machinery guard system includes a mounting bracket assembly coupled to the front of the mining shovel frame. The crowd machinery guard system also includes at least one support leg rotatably coupled to the mounting bracket assembly, and an impact plate assembly coupled to the support leg. The impact plate assembly includes an impact plate configured to receive dipper impacts, at least one support leg bracket coupled to the impact plate, and at least one cushion subassembly including a dampening portion. The crowd machinery guard system is configured to absorb and distribute the force of dipper impacts.

Abstract: A transfer apparatus which performs long-distance transfer at a high speed, while preventing dimensions of the apparatus from increasing. Specifically, a transfer apparatus transfers a work to a pressing machine The transfer apparatus is provided with a base section, a follower arm, which is connected to the base section on the base-section end side such that the follower arm can rotate and vertically slide, and a first driving arm which is rotatably connected to the base section on the base-section end side. The transfer apparatus also includes a driving arm, which is rotatably connected to the first driving arm on the base-section end side and rotatably connected to the follower arm on the leading end side, and a holding apparatus arranged on the leading end side of the follower arm for holding the work.

Abstract: An invert assembly for an individual section glassware forming machine includes an invert base that is oscillated about an axis between angularly spaced apart first and second positions, a double ended ball screw positioned co-axially with the axis and having spaced apart oppositely threaded portions, first and second nuts each threadably engaging one of the oppositely threaded portions of the ball screw so that the nuts reciprocate toward and away from each other in response to rotation of the ball screw, and first and second neck ring arms respectively engaging the first and second nuts so that the neck ring arms reciprocate toward and away from each other along the axis with the first and second nuts. Preferably, the invert base is oscillated about the axis by a first reversible electric motor, and the ball screw is driven for rotation in opposed directions by a second reversible electric motor to move the nuts and neck ring arms toward and away from each other along the axis.

Abstract: The present invention provides transport apparatus for transporting and aculating an article into and out of a housing having limited access, and includes a lifting beam having a curved shape to which is attached a lifting assembly. A hoist device is connected to the lifting assembly for raising and lowering the entire transport apparatus and also includes a worm-drive assembly for moving the lifting assembly relative to the lifting beam to thereby articulate an article about a first axis. In addition, one end of the lifting beam includes a rotational mechanism which is connected to a second worm-drive assembly. Operation of the second worm-drive assembly allows the article to be rotated relative to the lifting beam which allows the article to be rotated relative to a second axis. The combined operations of hoisting and movement about the two axes allows the article to be articulated in any direction for insertion or removal from a housing having limited access.

Abstract: A crane having a fixed mast and a boom pivotally mounted at the top of the mast for movement in a horizontal plane through at least 180.degree. and in a vertical plane downwardly from the horizontal plane at any position of the boom relative to the vertical axis of the mast, a load carrying trolley movable along the length of the boom, hydraulic means located at the top of the mast controlling the movement of the boom in the horizontal plane and hydraulic means between the boom and the mast controlling movement of the boom in the vertical plane.
