Claim 1
Independent Claim
288 words
A setting tool for collapsible shank toggle bolts of the type which include a stop flange, a collapsible shank extending from said flange, a threaded receiver portion at the distal end of said shank and a bolt member having a head disposed adjacent said flange and a shank axially movable within said shank of said toggle and threadedly engaging said receiver portion, comprising a frame member including a base plate having an inner and an outer face and a slot formed between said faces, said slot including first portions sized to permit the passage therethrough of said head and shank of said bolt, and other portions sized to prevent the passage of said flange, a puller plate abutting said inner face of said base plate, said puller plate including a slot in registry with said slot of said base plate, said slot of said puller plate including first portions sized to permit the passage therethrough of said head and shank of said bolt and other portions sized to prevent the passage of said head and permit the passage of said shank, said first and other portions of said slot of said base plate being in registry with said first and other portions, respectively, of said slot of said pulley plate, whereby a said toggle may be mounted in clamping relation of said plates with said flange engaging said outer face of said base plate and the under surface of said head engaging the face of said puller plate remote from said base plate, and mechanical advantage means on said frame engaging said puller plate for shifting said puller plate inwardly away from said base plate, thereby to shift said receiver portion toward said flange and collapse said shank.
Claim 2

A setting tool for collapsible shank toggle bolts of the type which include a stop flange, a collapsible shank extending from said flange, a threaded receiver portion at the distal end of said shank and a bolt member having a head disposed adjacent said flange and a shank axially movable within said shank of said toggle and threadedly engaging said receiver portion, comprising a frame member including a base plate having an inner and an outer face and a slot formed between said faces, said slot including first portions sized to permit the passage therethrough of said head and shank of said bolt, and other portions sized to prevent the passage of said flange, a puller plate abutting said inner face of said base plate, said puller plate including a slot in registry with said slot of said base plate, said slot of said puller plate including first portions sized to permit the passage therethrough of said head and shank of said bolt and other portions sized to prevent the passage of said head and permit the passage of said shank, said first and other portions of said slot of said base plate being in registry with said first and other portions, respectively, of said slot of said pulley plate, whereby a said toggle may be mounted in clamping relation of said plates with said flange engaging said outer face of said base plate and the under surface of said head engaging the face of said puller plate remote from said base plate, and mechanical advantage means on said frame engaging said puller plate for shifting said puller plate inwardly away from said base plate, thereby to shift said receiver portion toward said flange and collapse said shank.
Claim 3
Dependent Claim
40 words
Apparatus in accordance with claim 1 and including guide means interposed between said base plate and puller plate for guiding said puller plate in a linear path relative to said base plate responsive to activation of said mechanical advantage means.
Claim 4
Dependent Claim
33 words
Apparatus in accordance with claim 1 wherein said mechanical advantage means comprises a lazy tongs linkage having a fixed fulcrum mounted to said frame and a movable fulcrum mounted to said puller plate.
Claim 5
Dependent Claim
55 words
Apparatus in accordance with claim 1 wherein said slots of said base plate and said puller plate open to lateral edge portions of said plates, whereby a said toggle bolt may be inserted into said clamping position responsive to a movement of said bolt in a direction parallel to the plane of said base plate.
Claim 6
Dependent Claim
27 words
Apparatus in accordance with claim 1 wherein said slots taper progressively from a wide dimension at said first portion to a narrowest dimension adjacent said other portion.
Claim 7
Dependent Claim
284 words
A setting tool for collapsible shank toggle bolts of the type which include a stop flange, a collapsible shank extending from said flange, a threaded receiver portion at the distal end of said shank and a bolt member having a head disposed adjacent said flange and a shank axially movable within said shank of said toggle and threadedly engaging said receiver portion, comprising a frame member including a base plate having an inner and an outer face and a slot formed between said face, said slot having an open end portion extending to a lateral edge of said base plate and including gripper portions sized to permit the passage therethrough of said shank of said bolt but not said flange, a puller plate abutting said inner face of said base plate, said puller plate including a slot having an open end extending to a lateral edge of said plate, said slot including gripper portions sized to permit the passage therethrough of said shank of said bolt but not said head of said bolt, said slots of said plates being disposed in registry and having said open ends faced in the same direction whereby a said toggle bolt may be mounted in clamping relation of said plates responsive to a movement of said toggle in the direction of said slots, with said flange engaging said outer face of said base plate and the under surface of said head engaging the face of said puller plate remote from said base plate, and mechanical advantage means on said frame engaging said puller plate for shifting said puller plate inwardly away from said base plate, thereby to shift said receiver portion toward said flange and collapse said shank.
Claim 8
Dependent Claim
284 words
A setting tool for collapsible shank toggle bolts of the type which include a stop flange, a collapsible shank extending from said flange, a threaded receiver portion at the distal end of said shank and a bolt member having a head disposed adjacent said flange and a shank axially movable within said shank of said toggle and threadedly engaging said receiver portion, comprising a frame member including a base plate having an inner and an outer face and a slot formed between said face, said slot having an open end portion extending to a lateral edge of said base plate and including gripper portions sized to permit the passage therethrough of said shank of said bolt but not said flange, a puller plate abutting said inner face of said base plate, said puller plate including a slot having an open end extending to a lateral edge of said plate, said slot including gripper portions sized to permit the passage therethrough of said shank of said bolt but not said head of said bolt, said slots of said plates being disposed in registry and having said open ends faced in the same direction whereby a said toggle bolt may be mounted in clamping relation of said plates responsive to a movement of said toggle in the direction of said slots, with said flange engaging said outer face of said base plate and the under surface of said head engaging the face of said puller plate remote from said base plate, and mechanical advantage means on said frame engaging said puller plate for shifting said puller plate inwardly away from said base plate, thereby to shift said receiver portion toward said flange and collapse said shank.
