Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
179 words
In an apparatus for spraying die cavities in a pair of relatively movable dies which open and close including spraying means movable between the dies during die opening, the dies and spraying apparatus being subject to damage in the event the dies close on the apparatus, mechanical means operated by die movement for moving the spraying means into the space between the dies during die opening and into position for spraying the dies for positively removing the spraying means from the space during die closing comprising an arm pivotally secured at one end to one of the dies and attached at the other end to the spraying means for support and guidance thereof, a first link having one end rigidly connected with the said one of the arm for movement therewith, and a second link having its ends respectively pivotally connected to the other of the dies and to the other end of the first link so that relative movement of the dies causes pivotal movement of the links and consequently of the arm to move the spraying means.
Claim 2
Dependent Claim
179 words
In an apparatus for spraying die cavities in a pair of relatively movable dies which open and close including spraying means movable between the dies during die opening, the dies and spraying apparatus being subject to damage in the event the dies close on the apparatus, mechanical means operated by die movement for moving the spraying means into the space between the dies during die opening and into position for spraying the dies for positively removing the spraying means from the space during die closing comprising an arm pivotally secured at one end to one of the dies and attached at the other end to the spraying means for support and guidance thereof, a first link having one end rigidly connected with the said one of the arm for movement therewith, and a second link having its ends respectively pivotally connected to the other of the dies and to the other end of the first link so that relative movement of the dies causes pivotal movement of the links and consequently of the arm to move the spraying means.
Claim 3
Dependent Claim
179 words
In an apparatus for spraying die cavities in a pair of relatively movable dies which open and close including spraying means movable between the dies during die opening, the dies and spraying apparatus being subject to damage in the event the dies close on the aPparatus, mechanical means for moving the spraying means into the space between the dies during die opening and positively removing the spraying means from the space during die closing comprising a pair of parallel arms of equal length each pivotally secured at one end to one of the dies and pivotally secured at the other end to the spraying means for support and guidance thereof, a first link having one end rigidly connected with the said one end of one of the arms for movement therewith, and a second link having its ends respectively pivotally connected to the other of the dies and to the other end of the first link so that relative movement of the dies causes pivotal movement of the links and consequently of the arms to move the spraying means.
