PIPE-COVERING.

Specification of Letters Patent.

Patented Feb. 24, 1920.

To all whom it may concern:

Be it known that we, NICHOLAS S1M0N0- won, a citizen of Jugo-Slavia, residin at New York, county of New York, and tate of New York, and SAMUEL SIMONOVICH, a citizen of Jugo-Slavia, residing at New York, county and State of New York, have invented certain new and useful Improvements in Pipe-Coverings, of which the following is a specification.

This invention relates to improvements in coverings for pipes used in conveying hot or cold liquids or gases, so as to prevent the loss of heat by radiation from the surface of the pipes, or the entrance of cold therewithin.

This object is attained by the novel construction and combination of parts hereinafter described and shown in the accompanying drawings, forming a material part of this disclosure, and in which- Figure 1 is a perspective and sectional view showing a covering as applied to an ordinary water pipe, and

Fig. 2 is a similar view showing a modified form of the covering as applied to a steam pipe.

Referring to the drawings in detail, the numeral 10 indicates an ordinary cylindrical tube or pipe adapted to convey liquids, gases and the like. the pipe being of the ordinary type usually employed for such purposes.

Surrounding the pipe 10 is a cover 11, made of felted asbestos fibers, of a uniform thickness, and divided in two equal sections, as are all the subsequent covering applied to the pipe.

Circumjacent to the asbestos felt covering 11 is a thicker covering of wool felt 12, in turn encircled by a relatively thin cover 13, of felted hair, enveloped in an outer covering of wool felt 14, and confined in a wrapper 15 made of muslin, canvas or the llke, in turn inclosed by an outer covering 16 of strong linen.

The semi-circular sections of the pipe covering are held in position and adjusted upon the pipe by a plurality of thin metallic bands 17, one of their ends being turned rentrantly and secured by rivets 19 and inclosing a flattened ring or link 20, in which is engaged the opposite end 21 of the band, the material being of flexible and pliable nature, adapted to draw the pipe coverings tightly together, so as to confine the same when in an adjusted position.

In the adaptation shown in Fig. 2, an inner covering of asbestos felt 11 surrounds the pipe 10, circumjacent to which is a relatively thicker covering of wool felt 22, surrounded by another asbestos felt covering 23, overlaid by an exterior covering of wool felt 24, held in position by

easing elements

15 and 16, and clam ed by a metallic strap or band formed in tfie manner previously described.

From the foregoing it will be seen that an effective and practical pipe covering has been disclosed, preventing t e loss of heat by radiation and conversely, preventing cold from entering and affecting the contents of the pipe.

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

'1. A pipe covering comprising layers of asbestos wool and hair, shredded and disposed substantially as described, the layers being formed in two equal semi-circular sections, and means for clamping said layers on the pipe.

2. A pipecovering comprising layers of felted asbestos fiber, one of said layers being disposed directly on the surface of the pipe, layers of felted wool, one of said wool layers being disposed between said asbestos layers, and the other circumjacent thereto, covering said layers, and means for securing said layers in position on a pipe.

3. A steam pipe covering comprising an innermost layer of asbestos felt, a second layer of'wool felt relatively thicker than the first named layer, a third relatively thin layer of hair felt, a fourth layer of wool felt, a muslin cover disposed thereover, a lining over said muslin cover, and a plurality of pliable bands for uniting the sections of said coverings firmly with the surface of a pipe.

In testimony whereof we have afiixed our signatures.
