Abstract
Abstract A saddle for a U-bolt clamp is formed from a sheet metal blank rolled at its ends in opposite directions to provide tubular portions which receive the bolt legs in axially slidable relation. Under the clockwise torque transmitted to the ends of the tubular portions as the securing nuts are drawn up on the bolt legs against the saddle, the force exerted on both legencompassing tubular portions of the saddle will act to wind or constrict both tighter on the bolt legs or at least will prevent them from twisting loose on the legs. The web of the saddle is reinforced by an integral portion extending between the bolt legs.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
83 words
In a U-bolt clamp assembly having a U-bolt, said U-bolt comprising a bight portion and a pair of legs, a pair of tubular portions axially slidable on said legs, a saddle web integral with and spanning the space between said tubular portions, and securing nuts threaded on the free ends of the bolt legs for drawing up against the adjacent ends of the tubular portions; the tubular portions in cross section being unclosed loops trained clockwise in opposite directions from the saddle web.
Claim 2
Dependent Claim
83 words
In a U-bolt clamp assembly having a U-bolt, said U-bolt comprising a bight portion and a pair of legs, a pair of tubular portions axially slidable on said legs, a saddle web integral with and spanning the space between said tubular portions, and securing nuts threaded on the free ends of the bolt legs for drawing up against the adjacent ends of the tubular portions; the tubular portions in cross section being unclosed loops trained clockwise in opposite directions from the saddle web.
Claim 3
Dependent Claim
82 words
In the clamp assembly of claim 1, said saddle web being planar, the ends of the tubular portions proximate the securing nuts being in a plane common thereto and which is perpendicular to the plane of the web, each tubular portion being in cross section a circular loop bisected by the plane of the web, one loop being trained initially clockwise from one side of the web, and the other loop being trained initially clockwise from the opposite side of the web.
Claim 4
Dependent Claim
64 words
A U-bolt clamp saddle comprising a planar sheet metal blank, a pair of tubular portions thereon in parallel spaced relation thereon and integral therewith, one tubular portion being in cross section a clockwise trained loop open at one side of the blank, and the other tubular portion being a clockwise trained loop in cross section and open at the other side of the blank.
Claim 5
Dependent Claim
64 words
A U-bolt clamp saddle comprising a planar sheet metal blank, a pair of tubular portions thereon in parallel spaced relation thereon and integral therewith, one tubular portion being in cross section a clockwise trained loop open at one side of the blank, and the other tubular portion being a clockwise trained loop in cross section and open at the other side of the blank.
Claim 6
Dependent Claim
122 words
A U-bolt clamp saddle comprising a planar, oblong sheet metal member, said member having a relatively thin web portion of uniform thickness forming a work engaging edge portion, and a tubular portion at each end of said member, said tubular portions each adapted to receive a leg portion of a U-shaped bolt to form an opening to receive the work, and reinforcement means formed integral with said oblong member for an appreciable extent at the lower portion thereof and closely adjacent the lower end of said tubular portions receiving the leg portions of the U-shaped bolt, said reinforcing means being distally spaced below the work engaging edge portion, said reinforcement means being an edge portion of the blank doubled back upon itself.
Claim 7
Dependent Claim
122 words
A U-bolt clamp saddle comprising a planar, oblong sheet metal member, said member having a relatively thin web portion of uniform thickness forming a work engaging edge portion, and a tubular portion at each end of said member, said tubular portions each adapted to receive a leg portion of a U-shaped bolt to form an opening to receive the work, and reinforcement means formed integral with said oblong member for an appreciable extent at the lower portion thereof and closely adjacent the lower end of said tubular portions receiving the leg portions of the U-shaped bolt, said reinforcing means being distally spaced below the work engaging edge portion, said reinforcement means being an edge portion of the blank doubled back upon itself.
Claim 8
Dependent Claim
36 words
In the clamp saddle of claim 4, the blank having a work indenting edge portion spaced above the edge of said doubled back portion, the indenting edge being curved and the doubled back edge being straight.
Claim 9
Dependent Claim
123 words
A U-bolt clamp saddle comprising a planar, oblong sheet metal member, said member having a relatively thin web portion of uniform thickness forming a work engaging edge portion, and a tubular portion at each end of said member, said tubular portions each adapted to receive a leg portion of a U-shaped bolt to form an opening to receive the work, and reinforcement means formed integral with said oblong member for an appreciable extent at the lower portion thereby and closely adjacent the lower end of said tubular Portions receiving the leg portions of the U-shaped bolt, said reinforcing means being distally spaced below the work engaging edge portion, said reinforcement means being a downwardly extending enlargement of the blank in the plane thereof.
Claim 10
Dependent Claim
123 words
A U-bolt clamp saddle comprising a planar, oblong sheet metal member, said member having a relatively thin web portion of uniform thickness forming a work engaging edge portion, and a tubular portion at each end of said member, said tubular portions each adapted to receive a leg portion of a U-shaped bolt to form an opening to receive the work, and reinforcement means formed integral with said oblong member for an appreciable extent at the lower portion thereby and closely adjacent the lower end of said tubular Portions receiving the leg portions of the U-shaped bolt, said reinforcing means being distally spaced below the work engaging edge portion, said reinforcement means being a downwardly extending enlargement of the blank in the plane thereof.
