SPECIFICATION forming part of Letters Patent N 0. 397,822, dated February 12, 1889.

Application filed April 17, 1888 To all whom it may concern:

Be it known that I, VILLIAM M. SUHR, of the city, county, and State of New York, have invented a new and Improved Covering, of which the following is a full, clean-and exact description.

The object of the invention is to provide a new and improved covering adapted for protecting boilers, steam or water pipes, or any hot or cold surfaces requiring a ive and protecting covering.

The invention is an improvement in the coveri n g for which Letters Patent N 0. 383,599 were granted to me May 29, 1888'; and it consists of a covering provided with an inner wall composed-of fire-proof material, gauze,

and waterproof material, of an outer Wall composed of fabric, fire-proof material, gauze, and water-proof material, and of a filling located between the said two walls and made of mineral-wool, rock wool, orisimilar substance.

The invention also consists of certain parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.

v (\I I Reference is to be .had to the accompa-nylng drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure 1 is a sectional end elevation of the improvement in an open position, and Fig. 2 is a like view of the same in a closed position as applied to a pipe.

The improved covering A is provided with an inner wall, 13, and an outer Wall, between which isplaced a filling,- D, made of a nonconducting and protecting materialsuch as mineral wool, rock wool, asbestus fiber, hair, cork, orlike substance The inner wall, B, is made of three layers, of which the outer one, E, is made of tire-proof material-such, as asbestuson the inside of which is glued or otherwise secured the gauze F, which is again covered by the third layer, G, formed of The outer wall, 0, is composed of four layers, of which the outer one, H, is formed by a fabric of cotton, hemp,

Wool, or other similar material saturated in .TtfiI'Q-pIOOf liquidsuch as silicate of soda,

alum, or other substance. The layer I next as asbestus-and is covered by a gauze, J, soaked in a fireproof substance-such as silicate of soda-and this gauze J is covered by a Water-proof material, K, similar to the one Wall, B. I

The fabric II is provided with ping end, 11, adapted to lap over, as'shown in Fig. 2, so as to secure the covering firmly to the pipe N or to the boiler to which it is to be applied, the overlapping end H being secured by tacks, glue, or in any other suitable manner to the other end of the fabric.

In order to hold the filling D in place between the tWo walls, I employ a stiffener, L, placed in the, middle of the filling D, and preferably made of wire-gauze covered by a Water-proof or fire-proof material such as that .outer walls, B and C.

for covering straight surfaces or in the manner illustrated in tlgp drawings, so as to be better applied to on 'ed surfaces, as boilers, pipes, (to The sides'of the covering are then left open, so that. the pipe can be placed on the inner warn, as shown in Fig. 1, and then the sides are closed until they meet and locked in place by the overlapping end H of the fabric H. It will be seen that the covering protects the boiler, pipe, or other surface to which it is applied from both heat non-conductive, water-proof, and fire-proof. The water-proof material forms a protection against moisture and exposure to water or steam.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. A pipe-covering comprisingan inner and outer wall between which is placed a filling, said inner and outer walls each being made of above described in relation to the inner and water, being to the fabric H is of fire-proof materialsuch an ov-erlap-.

The entire covering is made either in sheets a fire-proof material, a water-proof material,

7o above described in reference to the inner and each made of a fire-proof material, a water water-proof material, andag'auze between the [0 proof material, and a connecting-gauze betwo, in combination with a filling placed between the two, in combination with a filling V tween the said two walls and a stiffener placed between the two said walls and a fabplaced in the said filling, substantially as ric secured on the outer Wall and provided shown and describe with an overlapping end, substantially as. \VILLIAM M. SUHR. shown and described. Witnesses:
