Abstract
Abstract A grounding and clamping device comprised of a combination conduit receiving and locking member and flange clamp to rigidly secure and ground a metallic electrical conduit to a supporting metallic structure. A pair of adjustably coupled recessed members provide a conduit receiving cavity therebetween within which the conduit may be secured; the recessed members may be tightened about the conduit placed within the cavity by threadably engaging threaded extensions protruding from one recessed member and through registering apertures in the other. Coupled to and extending from one of the recessed members is a flange clamp adapted to rigidly secure the recessed members to a support member. At each end of the flange-adapted recessed member is a locking means threadably coupled thereto and extending into the clamp aperture to provide biting engagement between the recessed members and the support member.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
246 words
A grounding and clamping device comprising: a first body portion; a second body portion; means for coupling said first body portion to said second body portion to form a conduitreceiving cavity therebetween; clamping means coupled to said first body portion to clamp said first body portion to a support member; and adjustable locking means threadably coupled to said first body portion and extending therethrough to contact in locking engagement an adjacent surface of a support member interposed between said first body portion and said clamping means; said first body portion having at least one generally recessed surface disposed substantially transverse to the longitudinal axis of said first body portion; said second body portion having a similar generally recessed surface disposed substantially transverse to the longitudinal axis of said second body portion; each of said generally recessed surfaces being defined by at least two pair of surfaces, each surface of one said pair of surfaces in oblique planar relationship one to the other, each said pair of surfaces disposed longitudinally along said first and second body portions, each said pair of surfaces communicating at a first edge of each of said surfaces forming a crest, the second edge of each of said surfaces communicating with opposite sides of said first and second body portions, whereby a conduit engaged between said first and second body portions may be rigidly secured therebetween, the longitudinal axis of said conduit in offset angular relationship with the axis of said conduit-receiving cavity.
Claim 2
Dependent Claim
246 words
A grounding and clamping device comprising: a first body portion; a second body portion; means for coupling said first body portion to said second body portion to form a conduitreceiving cavity therebetween; clamping means coupled to said first body portion to clamp said first body portion to a support member; and adjustable locking means threadably coupled to said first body portion and extending therethrough to contact in locking engagement an adjacent surface of a support member interposed between said first body portion and said clamping means; said first body portion having at least one generally recessed surface disposed substantially transverse to the longitudinal axis of said first body portion; said second body portion having a similar generally recessed surface disposed substantially transverse to the longitudinal axis of said second body portion; each of said generally recessed surfaces being defined by at least two pair of surfaces, each surface of one said pair of surfaces in oblique planar relationship one to the other, each said pair of surfaces disposed longitudinally along said first and second body portions, each said pair of surfaces communicating at a first edge of each of said surfaces forming a crest, the second edge of each of said surfaces communicating with opposite sides of said first and second body portions, whereby a conduit engaged between said first and second body portions may be rigidly secured therebetween, the longitudinal axis of said conduit in offset angular relationship with the axis of said conduit-receiving cavity.
Claim 3
Dependent Claim
23 words
A grounding and clamping device as defined in claim wherein each said surface of said pair of surfaces is at least partially serrated.
Claim 4
Dependent Claim
19 words
A grounding and clamping device as defined in claim 1 wherein the plane of said surfaces is substantially curvilinear.
Claim 5
Dependent Claim
232 words
A grounding and clamping device comprising: a first body portion; a second body portion; means for coupling said first body portion to said second body portion to form a conduit-receiving cavity therebetween; and clamping means coupled to said first body portion to clamp said first body portion to a support member; said first body portion having at least one generally recessed surface disposed substantially transverse to the longitudinal axis of said first body portion; said second body portion having a similar generally recessed surface disposed substantially transverse to the longitudinal axis of said second body portion, said recessed surfaces defining a cavity wherein a conduit seated within said cavity may be rigidly secured therebetween; said clamping means being a generally L-shaped portion coupled to said first body portion, the open portion of said L-shaped portion and an adjacent surface of said first body portion defining a slot therebetween for engaging a support member; said L-shaped portion being the looped end portion of a threaded U-bolt, said looped end portion having a substantially C-shaped profile axially disposed in substantially parallel planar relationship with and offset from the plane of the threaded leg extensions of said U-bolt, at least one of said threaded leg extensions extending through an aperture in one of said upturned portions of said first body portion and through a registering aperture in said web portion of said second body portion.
Claim 6
Dependent Claim
232 words
A grounding and clamping device comprising: a first body portion; a second body portion; means for coupling said first body portion to said second body portion to form a conduit-receiving cavity therebetween; and clamping means coupled to said first body portion to clamp said first body portion to a support member; said first body portion having at least one generally recessed surface disposed substantially transverse to the longitudinal axis of said first body portion; said second body portion having a similar generally recessed surface disposed substantially transverse to the longitudinal axis of said second body portion, said recessed surfaces defining a cavity wherein a conduit seated within said cavity may be rigidly secured therebetween; said clamping means being a generally L-shaped portion coupled to said first body portion, the open portion of said L-shaped portion and an adjacent surface of said first body portion defining a slot therebetween for engaging a support member; said L-shaped portion being the looped end portion of a threaded U-bolt, said looped end portion having a substantially C-shaped profile axially disposed in substantially parallel planar relationship with and offset from the plane of the threaded leg extensions of said U-bolt, at least one of said threaded leg extensions extending through an aperture in one of said upturned portions of said first body portion and through a registering aperture in said web portion of said second body portion.
