Filed:

Aug 7, 2006

Appl. No.:

11/500201

Inventors:

William Allan Hunter - Palatine IL, US

Assignee:

Hunter Automated Machinery Corporation - Schaumburg IL

International Classification:

B22D 47/00

US Classification:

164130, 164324

Abstract:

Method and apparatus for feeding sand molds from multiple sand mold forming stations to a common metal pouring station. The method and apparatus of this invention utilize walking-beam-type conveyors having spaced apart fixed outboard rails and a central reciprocating rail. Walking-beam conveyors are disposed in perpendicular directions with a junction therebetween that allows for a perpendicular change in direction. The method and apparatus of this invention allow multiple parallel walking-beam conveyors to feed sand molds to a single junction for transfer to a metal pouring station.

Gateway Industries, Inc. - Hazel Crest IL

International Classification:

A44B 1128

US Classification:

24640

Abstract:

A seat belt buckle having a buckle frame and a pivotal latching member mounted therein includes a single spring for biasing a push button toward an outer position and for ejecting a tongue plate from the frame when the latch mechanism is in its open position. The preferred spring is a coil spring which is loaded in tension in an extended configuration. In the preferred embodiment, the spring additionally provides biasing force to lock the latch mechanism in its latching position after insertion of the tongue plate into the buckle frame and provide biasing force to maintain the latching member in its open position prior to insertion of the tongue plate.

Heatherwill Company - Inverness-Palatine IL

International Classification:

B22C 920
B22C 1104

US Classification:

164 24

Abstract:

A machine for forming foundry moulds includes a turret supporting spaced mould frames, each of the latter having a mould portion formed therein by rotation of the turret toward a sand filling and compacting station and away therefrom. The completed mould portion may be moved to a position where a core can be set thereon and then moved to a position where the mould portions are positioned one atop another to make a stack of finished and cored moulds. When the moulds are not cored, a pair of said filling and compacting stations are provided, the turret oscillating or rotating unidirectionally from a loading position to a delivery position. Where a pair of filling and compacting stations are provided for forming cope and drag mould portions, the turret oscillates to place the two mould portions in proper position to form a mould comprised of cope and drag portions. The machine makes foundry moulds capable of being placed one atop another, a pair of moulds defining a pouring lip connected to a pouring channel in turn connected to runners and mould cavities.

International Classification:

B22D 4702

US Classification:

164130

Abstract:

The upper level of a pouring conveyor receives sand molds and conveys the empty molds to a pouring station wherein molten material is deposited therein to form castings. Each mold is provided with a supportive weight and jacket before pouring. After the castings have been poured, the molds are transferred to the lower level of the pouring conveyor for cooling purposes, and then back to the upper level to remove the weight and jacket. The sand molds are then transferred to the upper level of a cooling conveyor and are deposited into trays provided on the cooling conveyor. Each tray is adapted to receive a plurality of molds to enable the molds to move from serial to parallel movement. An indexable pusher arm is provided to accurately place each mold in a respective tray to insure proper spacing for uniform cooling. After each tray has traversed the upper and lower levels of the cooling conveyor, the molds are removed from the trays and the sand is broken away to reveal the castings for harvest.
