Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
117 words
Apparatus for deflecting a molded structure from a molding machine comprising a mold with separable parts within the machine, a movable member mounted on the machine, a flexible rod secured to said movable member for entering the space between the molded structure and one of said parts when the parts are separated, said flexible rod including a protuberance having an inwardly and downwardly sloping surface at an intermediate position between the ends of said rod, and deflection means having a cam surface for engaging the inwardly and downwardly sloping surface of said protuberance during a limited portion of the stroke of said flexible rod to thereby deflect said rod and kick said molded structure from said mold.
Claim 2
Dependent Claim
117 words
Apparatus for deflecting a molded structure from a molding machine comprising a mold with separable parts within the machine, a movable member mounted on the machine, a flexible rod secured to said movable member for entering the space between the molded structure and one of said parts when the parts are separated, said flexible rod including a protuberance having an inwardly and downwardly sloping surface at an intermediate position between the ends of said rod, and deflection means having a cam surface for engaging the inwardly and downwardly sloping surface of said protuberance during a limited portion of the stroke of said flexible rod to thereby deflect said rod and kick said molded structure from said mold.
Claim 3
Dependent Claim
38 words
Apparatus as defined in claim 1 wherein said protuberance surrounds said rod and engages said cam only after the portion of said rod extending from said protuberance to a free end of the rod has cleared said cam.
Claim 4
Dependent Claim
24 words
Apparatus as defined in claim 2 wherein said deflection means extends at a right angle with respect to said rod before the deflection thereof.
Claim 5
Dependent Claim
18 words
Apparatus as defined in claim 1 wherein a plurality of flexible rods are secured to said movable member.
Claim 6
Dependent Claim
17 words
Apparatus as defined in claim 4 wherein a separate deflection member is included for each separate rod.
Claim 7
Dependent Claim
14 words
Apparatus as defined in claim 1 wherein said flexible rod is made of nylon.
Claim 8
Dependent Claim
26 words
Apparatus as defined in claim 1 wherein said protuberance has a parabolic cross section centered on said rod, with the apex of said parabola pointing downwardly.
Claim 9
Dependent Claim
22 words
Apparatus as defined in claim 1 wherein said protuberance has a downwardly pointing conical configuration with a longitudinal axis on said rod.
Claim 10
Dependent Claim
26 words
Apparatus as defined in claim 1 wherein said cam surface is provided by a contoured aperture which engages said protuberance to provide deflection of said rod.
Claim 11
Dependent Claim
13 words
Apparatus as defined in claim 9 wherein said aperture has an open contour.
Claim 12
Dependent Claim
13 words
Apparatus as defined in claim 9 wherein said aperture has a closed contour.
Claim 13
Dependent Claim
19 words
Apparatus as defined in claim 1 wherein the position of said flexible rod on said movable member is adjustable.
Claim 14
Dependent Claim
17 words
Apparatus as defined in claim 1 wherein the position of the protuberance on said rod is adjustable.
Claim 15
Dependent Claim
15 words
Apparatus as defined in claim 1 wherein the position of said deflecting means is adjustable.
