Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
113 words
A corner miter clamp comprising plate means having integral upstanding side walls positioned at right angles to each other, said side walls having a break therein for providing entry for an insertion of a holding means through a mitered joint of a pair of frame members clamped in the right angle formed by said side walls, said plate means having a slot bisecting said right angle, clamp means slidably positioned in said slot for applying a corner pressure against a pair of mitered frame members, and separate means interposed between said corner pressure applying means and said frame members for divorcing a clamping action from any cocking of the frame or clamp parts.
Claim 2
Dependent Claim
113 words
A corner miter clamp comprising plate means having integral upstanding side walls positioned at right angles to each other, said side walls having a break therein for providing entry for an insertion of a holding means through a mitered joint of a pair of frame members clamped in the right angle formed by said side walls, said plate means having a slot bisecting said right angle, clamp means slidably positioned in said slot for applying a corner pressure against a pair of mitered frame members, and separate means interposed between said corner pressure applying means and said frame members for divorcing a clamping action from any cocking of the frame or clamp parts.
Claim 3
Dependent Claim
71 words
A corner miter clamp comprising means for applying a corner pressure against a pair of mitered frame members, and separate means interposed between said corner pressure applying means and said frame members for divorcing a clamping action from any cocking of the frame or clamp parts, wherein said corner pressure applying means comprises a wedge block member, and said separate means comprises a sliding block member driven by said wedge block.
Claim 4
Dependent Claim
71 words
A corner miter clamp comprising means for applying a corner pressure against a pair of mitered frame members, and separate means interposed between said corner pressure applying means and said frame members for divorcing a clamping action from any cocking of the frame or clamp parts, wherein said corner pressure applying means comprises a wedge block member, and said separate means comprises a sliding block member driven by said wedge block.
Claim 5
Dependent Claim
74 words
A corner miter clamp comprising means for applying a corner pressure against a pair of mitered frame members, and separate means interposed between said corner pressure applying means and said frame members for divorcing a clamping action from any cocking of the frame or clamp parts, wherein said corner pressure applying means comprises a first sliding block and said separate means comprises a second block disposed over and vertically retained by the first block.
Claim 6
Dependent Claim
74 words
A corner miter clamp comprising means for applying a corner pressure against a pair of mitered frame members, and separate means interposed between said corner pressure applying means and said frame members for divorcing a clamping action from any cocking of the frame or clamp parts, wherein said corner pressure applying means comprises a first sliding block and said separate means comprises a second block disposed over and vertically retained by the first block.
Claim 7
Dependent Claim
72 words
