Abstract
Abstract A covering for insulating a pipe including a U-shaped refractory cast having embedded in the refractory cast a U-bolt, and a plurality of parallel rods welded to the bolt to form a cradle-like frame. The ends of the U-bolt project from the sides of the cast. The cast is seated against the pipe and supported thereto by assembling a collar member on each of the U-bolt ends. The sides of the collar members extend over and are seated against the pipe. Nut members are threaded to the bolt ends and tightened against the collar members. Refractory material in plastic form is applied to the pipe, covering the exposed portion of the pipe, the U-bolt ends, collars and nuts assembled thereto to completely insulate the pipe.

Total Claims: 4
Claim 1
Independent Claim
156 words
An insulating form comprising: a longitudinal body having opposingly coterminous sides, and being U-shaped in cross section for longitudinal seating against a pipe, said coterminous sides having inwardly extending shoulders and opposingly slanted sides extending above said shoulders; a U-bolt embedded in a cross section of said body, the ends of said bolt projecting from said inwardly extending shoulders being threaded; a collar member on each end of said bolts and being within the confines of said sides extending above said shoulders, a part of said collar member extending over a part of said other side of said pipe; threaded means for connecting each of said threaded end of said bolt and moveable thereon against said collar member to wedge said collar member between said ends of said bolt and said part of said other side of said pipe; and a plurality of rods embedded longitudinally in said body, said rods being connected to said U-bolt.

An insulating form comprising: a longitudinal body having opposingly coterminous sides, and being U-shaped in cross section for longitudinal seating against a pipe, said coterminous sides having inwardly extending shoulders and opposingly slanted sides extending above said shoulders; a U-bolt embedded in a cross section of said body, the ends of said bolt projecting from said inwardly extending shoulders being threaded; a collar member on each end of said bolts and being within the confines of said sides extending above said shoulders, a part of said collar member extending over a part of said other side of said pipe; threaded means for connecting each of said threaded end of said bolt and moveable thereon against said collar member to wedge said collar member between said ends of said bolt and said part of said other side of said pipe; and a plurality of rods embedded longitudinally in said body, said rods being connected to said U-bolt.
Claim 3
Dependent Claim
237 words
An insulating pipe cover comprising: a plurality of cast forms each thereof having opposingly coterminous sides and being U-shaped in cross section, said plurality of forms abutting end to end to collectively cover one side of a pipe, said coterminous sides comprising inward extending shoulders and opposingly slanted sides extending above said shoulders; a U-bolt embedded in a cross section of each of said forms, the ends of said bolt projecting from said inwardly extending shoulders of said sides being threaded; a plurality of rods embedded longitudinally in each of said forms, said rods being connecting to said U-bolt; a collar member on each end of said bolt, said collar member being within the confines of said side extending above said shoulder, a part of said collar member extending over a part of said other side of said pipe; threaded means for connecting each of said threaded ends of said bolt and moveable thereon against said collar member to wedge said collar member against said end of said bolt and said part of said other side of said pipe for supporting said forms against said one side of said pipe; and heat insulating material in homogeneous form covering said other side of said pipe, said inwardly extending shoulders, said opposingly slanted sides of said plurality of cast forms, and encasing said ends of said bolts, said collar members and said means connecting said ends of said bolts.
