Abstract
Abstract A precast insulating material member for insulating a furnace skid rail includes a precast insulating material portion containing a crisscross reinforcing structure. The crisscross reinforcing structure is comprised of a pair of arcuate-shaped rods which are welded together intermediate their ends, each rod having end-eye portions which extend outwardly from the corners of the U-shaped precast insulating member. Positioned about the crisscross-shaped rods are coil members which assist in reinforcing the insulating portion of the member when the reinforcing structure is embedded within the insulating portion. The end-eye portions of the rods provide a mechanical lock of the insulating member to a skid rail pipe when the eye portions are moved into engagement with the outer surface of the skid rail pipe. The method of affixing the precast insulating member to a skid pipe includes the steps of; positioning the precast insulating member having exposed rod end-eye portions about the skid pipe, bending the exposed end-eye portions into engagement with the outer surface of the skid pipe to provide a mechanical lock of the insulating member to the pipe and filing the exposed surface of the pipe with a pliable insulating material to insulate and seal the skid pipe.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
116 words
A precast insulating material member for insulating about a skid rail pipe, including in combination a housing portion of insulating material having recessed corners thereon and adapted to be positioned about a skid rail pipe, a crisscross shaped rod portion and a coil member portion wrapped around said crisscross shaped rod portion, said rod and coil member positioned within said housing portion of insulating material, with said rod portion having end portions extending outwardly from the said recessed corners in said housing portion, and mechanical locking means associated with said end portions of said rod position when the same are engageable with the skid rail pipe to fix the insulating member to the skid rail pipe.
Claim 2
Dependent Claim
116 words
A precast insulating material member for insulating about a skid rail pipe, including in combination a housing portion of insulating material having recessed corners thereon and adapted to be positioned about a skid rail pipe, a crisscross shaped rod portion and a coil member portion wrapped around said crisscross shaped rod portion, said rod and coil member positioned within said housing portion of insulating material, with said rod portion having end portions extending outwardly from the said recessed corners in said housing portion, and mechanical locking means associated with said end portions of said rod position when the same are engageable with the skid rail pipe to fix the insulating member to the skid rail pipe.
Claim 3
Dependent Claim
24 words
The precast insulating member in accordance with claim 1 wherein said housing portion is U-shaped and includes a pair of leg extensions integral thereto.
Claim 4
Dependent Claim
26 words
The precast insulating member in accordance with claim 1 wherein said end portions of said rod portion are looped and engageable with the skid rail pipe.
Claim 5
Dependent Claim
34 words
The precast insulating member in accordance with claim 3 wherein said precast material member further includes fusion locking means for fusing said looped end portions of said rod portion to the skid rail pipe.
Claim 6
Dependent Claim
27 words
The precast insulating member in accordance with claim 2 wherein the length of said pair of leg extensions extends beyond the midpoint of the skid rail pipe.
Claim 7
Dependent Claim
42 words
The precast insulating member in accordance with claim 1 wherein when said rod portion and said end portions thereon are engageable with the skid rail pipe, substantially all of the pipe is enclosed by said rod portions and said end portions thereon.
Claim 8
Independent Claim
113 words
The method of affixing a precast insulating member to a skid pipe having a rub rail mounted thereon, including the steps of, positioning a U-shaped precast insulating member, having a crisscrossed shaped rod portion and coil structure portion wrapped around said rod portion within said insulating member with said rod portion having exposed end-eye portions extending outwardly from the insulating member thereon, about a skid pipe, bending the exposed end-eye portions of said rod portion into engagement with the skid pipe to provide a mechanical locking of the insulating member to the pipe, and filling the exposed surface of the pipe with a closure insulating material to insulate and seal the skid pipe.
Claim 9
Independent Claim
113 words
The method of affixing a precast insulating member to a skid pipe having a rub rail mounted thereon, including the steps of, positioning a U-shaped precast insulating member, having a crisscrossed shaped rod portion and coil structure portion wrapped around said rod portion within said insulating member with said rod portion having exposed end-eye portions extending outwardly from the insulating member thereon, about a skid pipe, bending the exposed end-eye portions of said rod portion into engagement with the skid pipe to provide a mechanical locking of the insulating member to the pipe, and filling the exposed surface of the pipe with a closure insulating material to insulate and seal the skid pipe.
Claim 10
Dependent Claim
43 words
The method of affixing a precast insulating member in accordance with claim 7 further including the step of fusing said end-eye portions of said crisscrossed rod portion structure to the skid pipe, after bending said end-eye portions into engagement with the skid pipe.
