Abstract
A U-bolt saddle clamp is disclosed having a double saddle design, wherein the primary saddle web is centered on the U-bolt axis to provide a substantially complete circular indentation on the coupled pipes to which it is applied in cooperation with the U-bolt. The spaced secondary saddle web functions as a fulcrum for the actuating or primary web and is cut out higher as it does not indent the pipe.
Claims6
A U-bolt clamp assembly adapted for sealing and interlocking a pair of telescoped metal tubes to each other, said clamp assembly comprising a U-bolt and a saddle, said U-bolt having substantially parallel legs threaded adjacent the free ends thereof, and a pipe engaging radius, said saddle having a front face, a rear face parallel to and spaced from said front face, and a top wall connecting said faces, said front face having a primary pipe-engaging radius on its ower edge, said rear face having a secondary pipe-engaging radius on its lower edge, U-bolt receiving apertures in said top wall, a vertical plane through the center line of said apertures being substantially coplanar with said front face pipe-engaging radius, and nuts for engagement on the threaded ends of the U-bolt legs, whereby when applied to a pair of telescoped tubes tightening of said nuts on said U-bolt ends against said top wall will result in the front face pipe-engaging radius and said U-bolt pipe-engaging radius compressing said tubes to form a substantially circumferential indentation therein, said rear face radius bearing upon the outer of the telescoped tubes and serving as a support.
In combination with a pair of telescopingly engaged metal tubes, a U-bolt clamp assembly for sealing and interlocking the tubes to each other, said clamp assembly comprising a saddle and a U-bolt, said U-bolt having substantially parallel legs threaded adjacent the free ends thereof, and a pipe-engaging radius, and nuts for engagement on the threaded ends of the U-bolt legs, the improvement comprising said saddle having a front face, a rear face parallel to and spaced from said front face, and a top wall connecting said faces, said front face having a primary pipe-engaging radius on its lower edge, said rear face having a secondary pipe-engaging radius on its lower edge, U-bolt receiving apertures in said top wall, a vertical plane through the center line of said apertures being substantially coplanar with said front face pipe-engaging radius, and wherein the inner one of said telescoped tubes is provided with a locating and rotation locking tab having an upstanding wall on the surface thereof, said outer tube having a slot formed therein receiving said tab, the rear face of said saddle member having a keyhole slot extending upwardly from the radius there of for reception of the wall of said tab, whereby tightening of said nuts on said U-bolt ends against said top wall will result in the front face pipe-engaging radius and said U-bolt pipe-engaging radius compressing said tubes to form a substantially circumferential indentation therein, said rear face radius bearing upon the outer of the telescoped tubes and serving as a support.
