Abstract

Abstract An adjustable barrier guard on a mechanical power press consisting of a three-panel cage for enclosing the sides and front of the point of operation of the machine. The side panels are hinged to the press and pivotally support the front panel with all swingable to fully open positions for set up purposes, being mechanically locked and electrically interlocked in the operating position. Each panel is a rectangular frame supporting upper and lower rows of vertically disposed facing loops being individually vertically adjustable and clamped to form a closed protective barrier or any aperture configuration between the rows.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 85 words
An adjustable barrier guard for mechanical power presses and the like, comprising a frame, barrier means supported on said frame to form a protective enclosure for a side of the press and providing at least one limited access opening therein, said barrier means including multiple vertical members individually adjustable relative to the frame in upper and lower series movable by such adjustment toward and away from each other to locate and determine the size and configuration of the access opening or openings within said frame.
Claim 2
Dependent Claim 85 words
An adjustable barrier guard for mechanical power presses and the like, comprising a frame, barrier means supported on said frame to form a protective enclosure for a side of the press and providing at least one limited access opening therein, said barrier means including multiple vertical members individually adjustable relative to the frame in upper and lower series movable by such adjustment toward and away from each other to locate and determine the size and configuration of the access opening or openings within said frame.
Claim 3
Dependent Claim 43 words
A guard as set forth in claim 1, wherein said frame is provided with means for pivotally mounting the same on said press for swinging movement relative to the operating area thereof, and further including means for locking said frame in closed condition.
Claim 4
Dependent Claim 50 words
A guard as set forth in claim 2, wherein said frame forms one side of a cage enclosing the machining area of the press, second and third similarly formed frames are provided with means for pivotal mounting to the press frame to swing between open and closed positions relative thereto.
Claim 5
Dependent Claim 45 words
A guard as set forth in claim 3, wherein said first frame is pivoted and lockable in closed condition to one of the second and third frames, with the former at the front and the lattEr at the respective sides of the press operating area.
Claim 6
Dependent Claim 46 words
A guard as set forth in claim 1, wherein said vertical members comprise loops of rigid material slidably mounted and lockable in said frame, the loops of said first series being offset with respect to and facing the loops of said second series of said frame.
Claim 7
Dependent Claim 62 words
A guard as set forth in claim 4, wherein each said frame comprises a generally rectangular structure having upper and lower straps spanning the same, with said vertical members thereof being guided in said straps, and clamping means for respectively engaging the upper and lower series thereof for locking the same releasably in vertically adjusted positioning at intermediate elevations within the frame.
Claim 8
Dependent Claim 59 words
A guard as set forth in claim 1, wherein said frame comprises a generally rectangular structure having upper and lower straps spanning said structure, with said vertical members being guided in said straps, and clamping means for respectively engaging the upper and lower series for locking the same releasably in vertically adjusted positioning at intermediate elevations within the frame.
Claim 9
Dependent Claim 43 words
A guard as set forth in claim 7, wherein said vertical members comprise loops of rigid material slidably mounted and lockable in said frame, the loops of said first series being offset with respect to and facing the loops of said second series.
Claim 10
Dependent Claim 59 words
A guard as set forth in claim 8, wherein said frame comprises a generally rectangular structure having upper and lower straps spanning said structure, with said vertical members being guided in said straps, and clamping means for respectively engaging the upper and lower series for locking the same releasably in vertically adjusted positioning at intermediate elevations within the frame.
