Abstract
Abstract A retrieval apparatus for die casting equipment which includes an extension tube for reaching into a die casting machine carrying an extension bar for increasing the range of the reach, there being pick-up jaws on the extension bar for clamping an ejected casting and returning it to a drop position over a quench tank, the jaws being movable to change the position of the casting so that it will orient properly with the quench tank and thus reduce the spacing required for the assembly. A mechanism for actuating the jaws from a release position to a pick-up position and again back to a release position together with a locking means for the jaws is incorporated to operate automatically during the extension and retraction motion of the slide tube and slide bar, and safety release mounting means are provided for the assembly to avoid damage due to possible malfunction.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
165 words
A casting retrieval machine for use with automatic die casting machines of the type having horizontally separable dies which comprises: a. a base, b. horizontal ways on said base, c. spaced slides supported on said ways, d. cross mount means supported on and spanning said slides, e. means to move said cross mount on said slides, f. an arm mount on said cross mount means, g. a slide tube slidably mounted in said arm mount, h. means on said cross-mount means for moving said slide tube in a projection stroke transversely of said spaced slides in a harmonic motion with the lowest acceleration and deceleration at the ends of the stroke, i. a slide bar slidably mounted in the end of said slide tube movable to project out of said tube in the same direction as the projection stroke of the tube, and j. means carried by said tube to project said slide bar in a projection stroke beyond the end of said slide tube.
Claim 2
Dependent Claim
165 words
A casting retrieval machine for use with automatic die casting machines of the type having horizontally separable dies which comprises: a. a base, b. horizontal ways on said base, c. spaced slides supported on said ways, d. cross mount means supported on and spanning said slides, e. means to move said cross mount on said slides, f. an arm mount on said cross mount means, g. a slide tube slidably mounted in said arm mount, h. means on said cross-mount means for moving said slide tube in a projection stroke transversely of said spaced slides in a harmonic motion with the lowest acceleration and deceleration at the ends of the stroke, i. a slide bar slidably mounted in the end of said slide tube movable to project out of said tube in the same direction as the projection stroke of the tube, and j. means carried by said tube to project said slide bar in a projection stroke beyond the end of said slide tube.
Claim 3
Dependent Claim
48 words
A casting retrieval machine as defined in claim 1 in which means is interposed between said cross mount and said arm mount to pivotally mount said arm mount on a vertical pivot post for movement in a horizontal plane and resilient means is disposed to resist said movement.
Claim 4
Dependent Claim
56 words
A casting retrieval machine as defined in claim 1 in which a vertical pivot post means is provided adjacent one of said slides to pivotally mount said arm mount means on said cross mount means, and means is provided adjacent the other of said slides to support said arm mount means in a swinging arc motion.
Claim 5
Dependent Claim
25 words
A casting retrieval machine as defined in claim 3 in which means is provided to resiliently bias said arm mount against said swing arc motion.
Claim 6
Dependent Claim
97 words
A casting retrieval machine as defined in claim 1 in which slide bearings are provided in said arm mount for said slide tube comprising a bearing housing and two pairs of opposed rollers mounted in said housing to contact the outer walls of said tube, at least one roller of each pair being mounted on an axle, and a plurality of resilient O-rings surrounding said axle and lodged in a recess in said housing to provide a resilient mount for said axles and allow compensatory movement of said rollers as said tube slides in said arm mount.
