Patent ID: 7434438

Claim:
A folding brake comprising: (a) a frame having a pair of vertically disposed and spaced side members; (b) a lower clamp means which is rigidly attached to each side member and which is disposed in a horizontal plane; (c) an upper clamp means which is movably positioned in relationship to said lower clamp means for selectively clamping a work piece positioned onto said lower clamp means; (d) a first pivot means for pivotally attaching a predetermined portion of said upper clamp means to a rear portion of said frame; (e) a first drive means for generating a clamping force and for pivotally moving said upper clamp means between a first position wherein a predetermined portion of said upper clamp means abuts such work piece positioned on said lower clamp means and applies said clamping force thereto and a second position wherein said predetermined portion of said upper clamp means is disposed at a predetermined distance from such work piece for enabling selective positioning of such work piece within said folding brake; (f) a bending means engageable with a portion of such work piece protruding beyond a front edge of said lower clamp means; (g) a second pivot means for pivotally attaching said bending means to said frame; (h) a second drive means for generating a bending force and pivoting said bending means in a first direction to engage such protruding portion of such work piece and apply said bending force thereto and in a second direction to disengage such bent portion of such work piece, said second drive means including: i, a first elongated member rigidly attached to a rear portion of said each side member of said frame, ii, a second elongated member pivotally connected to said each side member of said frame, iii. at least one cylinder pivotally connected to said first elongated member at one end and pivotally connected to said second elongated member at a second end, wherein a longitudinal axis of said at least one cylinder is perpendicular to a longitudinal axis of each of said first elongated member and said second elongated member, and iv. at least one arm member pivotally connected to said second elongated member at one end and pivotally connected to said pivot means at a second end; and (i) a control means for operating said first drive means and said second drive means.
