  • Patent number: 4148524
    Abstract: An improved seat, including a support member having a plurality of legs extending rigidly outwardly therefrom. An upright tubular inner column is affixed to said support member and is telescopically engaged by an upright tubular outer column whose top carries a device for supporting a person. A vertically pivotable footrest is carried by the ends of a pivot shaft which is, in turn, carried by the outer column. In one embodiment a locking pin, carried by the footrest, is selectively engageable with any one of a plurality of vertically arranged locking holes located in the inner column. In another embodiment, the locking pin, carried by the pivot, is located within the inner column, and selectively engages one pair of a plurality of pairs of vertically arranged locking slots in the inner column. In both embodiments, the height of the seat is adjusted by pivotably lifting the footrest to selectively engage and disengage the locking pin and its associated locking hole or locking slots.

  • Patent number: 4004905
    Abstract: An apparatus for forming glass containers wherein the glass is expanded to its final shape in a blow mold. A blowhead is brought onto vertical registry with the blow mold cavity. In the conventional Hartford I.S. forming machine, the mechanism for moving the blowhead onto and out of registry with the blow mold is pneumatically operated. The blowhead and the arm that supports the blowhead or blowheads is of considerable mass, and when an operator is required to change blow molds, or in some instances repair mechanisms which are at the blow mold location, it is necessary to maintain the blowhead in its up position. Air lockout systems have been used in the past but have not been foolproof. Accidents may occur. The present invention utilizes a mechanical lockout arrangement which locks the piston rod in its elevated position to avoid any possibility of the blowhead dropping.
