HEAT-OBSTRUCTING MIXTURE.

SPECIFICATION .forming part of Letters Patent No. 282,779, dated August '7, 1883.

Application filed February 26, 1833. (No model.)

T0 and whom it may concern.-

Be it known that I, WILLIAM H. Romans,-

of Hartford, in the county of Hartford and State of Connecticut, have invented a certain new and useful Improvement in Heat-Obstructing Mixtures, of which the following is a description, reference being had to the accompanying drawing, where the figure shows a pipe covered with a jacket made of my improved mixture for a part of the length shown.

III the drawing, the letter a denotes a meeight-tenths, (by weight;) hair, one-tenth, and mineral wool, one-tenth.

Itwill be readily understood that clay and hair and the mineral wool are to be moistened sufficiently to make the whole mixture plastic, 0 and that all the constituents of the mixture are to be thoroughly incorporated and intimately mixed. Mineral wool is peculiarly well adapted to preventing the passage of heat, and used in combination with clay and hair, 5 (to which other suitable and desirable heatobstructing elements may be added, if desired) it forms a mixture plastic enough at first for ready working, and tenacious enough afterward to hold itself in place. 40

I claim as my improvement The non-conducting mixture for covering pipes, boilers, &c., consisting of mineral wool one-tenth, hair, one-tenth, and clay eighttenths,mixed, substantially as described.

XYILLIAMII. ROGERS.
