- COVERING FOR STEAM BOILERS, PIPES, AND OTHER HEATED SURFACES.

SPECIFICATION forming part of Letters Patent No. 293,752, dated February 19, 1884; i Application filed October 10, 1883. (No model.)

To all whom it may concern: v

Be it known that we, EDWARD KRAHEN- BEIHL and PAUL Bron, of Allegheny, in the county of Allegheny and State ofv Pennsylva- 5 nia, have invented certain new and useful Improvements in Coverings for Steam Boilers,

Pipes, and other Heated Surfaces; and we do hereby declare the following to be a full, clear, and exact'description of the invention, such as I0 will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to an improvement in Y coverings for steam pipes, boilers, 820., the object being to provide a covering or jacket 15 which shall be so constructed that air-spaces shall be formed at intervals between the covering or jacket and boiler or pipe, and thus secure a more perfect non-conductor of heat; and with this end in view our invention con- 20 sists in certain novel features of construction, as will be hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a viewin perspective of a jacket or covering 25 embodying our invention. Fig. 2 is a similar view ofour improvement applied to a pipe.

Fig. 3 is a modification.

A represents a covering or jacket, made of 3o ofvlayers of paper secured together, or paperpulp, the inner surface of the same being lined .35 cover being also cut longitudinally to more easily apply it to the pipe B, the edges being securedin any desired manner. The covering is fluted or provided with corrugations O, the same being formed when the covering is compressed into shape. By these means air-spaces E are formed at intervals between the covering and the pipe or boiler, only a small portion of the covering coming in contact wit-h said pipe or boiler, and thus presenting but a small surface for the transmission of heat, the air-spaces 4 E forming a good non-conductor.

The corrugations may be formed in any desired shape, one form being shown in Fig. 3 of the drawings, and may'a'lso be made of any desired size.

Having fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-

A covering for steam boilers, pipes, &c. consisting of layers of paper firmly united together, 5 or paper-pulp, the said covering being lined or coated on its inner surface with asbestus, and

.the said lining and covering being fluted or corrugated longitudinally, whereby air-spaces are formed between the boiler and covering, 6 substantially as set forth. I

In testimony whereof. we have signed this specification in the presence of two subscribing witnesses.
