c. M. STOKES. PIPE COVERING. APPLICATION FILED JUNE 27' I910.

Patented Apr. 27, 1915.

I I N VENTOR Clam/we J1. 7 530/265 ATTORNEY FC *i CLARENCE M. STOKES, OF NORRI STOWN, PENNSYLVANIA.

PIPE-COVERING.

To all whom it may concern Be it known that I, CLARENCE M. S'roKEs, a citizen of the United States, residing at Norristown, in the county of Montgomery and State of Pennsylvania, have invented a certain new and useful Improvement in Pipe-Coverings, of which the following is a specification.

My invention relates to a new and useful improvement in pipe coverings, and has for its object to construct a device of this character of a number of ribbons of suitable insulating material, said ribbons being spirally wound,vone upon the other so that the uppermost ribbon always overlaps the joints of the ribbon beneatli.

In accomplishing the above named objects I cut an insulating material such as Wool or shoddy felt paper, known to the trade as deadening felt, into relatively long and narrow strips or ribbons. I then take a number of these ribbons and wind them spirally, one upon top of the other, using as many ribbons as necessary to produce the finished article of the desired thickness. Each outermost ribbon is so wound that it overlaps or covers the joints formed'by the inner ribbon, thus preventing the radiation of heat which would occur if the joints were in alinement. In practice, any desired insulating material may be used, or a number of insulating materialsmay be combined, that is, the

inner ribbon may be of asbestos, the next may be of wool felt, another of tar felt and so on, using any suitable insulating material, and if found desirable these ribbons may be corrugated so that when they are wound together air spaces will be formed which prevent the radiation of heat in a very effective manner.

With these ends in view, this invention consists in the details of construction and combination of elements -hereinafter set forth and then specifically designated by the claims.

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, I will describe its construction in detail, referring by letter tothe accompanying drawings Specification of LettersPatent.

forming a part of this specification, in

which- Figure 1 is a perspective view showing plain fabric used in the construction of the pipe; and Fig. 2, is a similar view, illustrating a modification.

In carrying out my invention as here embodied, A represents one of a number of ribbons of insulating material, which are spirally wound one upon the other forming layers until the desired thickness of the covering is obtained, each succeeding ribbon covering or overlapping the joints B formed by the preceding ribbon. In winding these ribbons an adhesive material, such as corn starch, silicate of soda or a composition of rubber, is placed between each pair of ribbons so that they always remain securely in position. The ribbons from which the covering is made are of deadening felt, (a paper,

made from wool or shoddy) asbestos, tar felt or any other suitable insulatmg material, and when making a covering all of the ribbons may be of any one of the insulating materials or two or more different 1nsulating materials may be used.

In Fig. 2, I have shown the several layers of fabric corrugated longitudinally to form air spaces when the several layers are assembled, and to increase the insulatmg properties of the pipe.

To place the covering upon a p1pe, 1t is cut or split longitudinally, then placed about the pipe and covered with canvas or a sheeting jacket pasted down to form a finish and also to.hold the covering in place upon the pipe. This sheeting jacket is used upon all P p E-rings of the present day, and it is therefore thought unnecessary to illustrate or describe the same in detail.

Having thus fully described my lnvention, what I claim as new and useful, iS

1. A pipe covering consisting of a spirally longitudinally as and for the purpose set said covering being split longitudinally for forth. the purpose described.
