CAP FOR STEAM-PIPE CLOTHING.
SPECIFICATION forming part of Letters Patent No. 276,044, dated April 17, 1883.
Application filed March 8, 1883. (No model.)
To all whom it may concern.-
Be it known that I, PETER HOLT, a citizen of the United States, and residing in Philadelphia, Pennsylvania, have invented a certain Cap for Steam-Pipe Clothing, of which the following is a specification.
My invention consists of a device, fully described hereinafter, for preventing the disintegration of the ends of the non-c0nducting clothing with which steam or hot-air pipes are often covered.
In the accompanying drawings, Figure 1 is a longitudinal section of a pipe, its non-cond nctingclothing, and annular cap for the same; Fig. 2, an end view of the cap, and Fig. 3 a perspective view of the same.
The non-conducting clothing B of the pipe A consists in the present instance of an inner layer, a, of asbestus board or composition, an outer layer, (6, which may be of the same material, and an intermediate layer, 1), of felt or hair. My invention, however, is not restricted to any specific kind of clothing, for all modern pipe-wrappings are apt to become disintegrated atthe points Where they are necessarily cut away for exposing the pipe wherever it is necessary to make attachments thereto. In order to prevent this I use an annular cap, D, made in two exactly similar parts, as best observed in the perspective view, Fig. 3, each part consisting of a semi -annular piece, 61, adapted to fit on the outside of the non-conducting clothing, a smaller semi-annular piece, 6, to fit to the pipe, and the beveled connecting-piece f, the whole being preferably composed of sheet or cast metal, and provided with lugs t' z, for receiving bolts by which the two parts are secured together, so as to inclose the clothing of the pipe at and near the end of the same. The intermediate beveled piece of one or both parts of the cap is of such a length that the beveled piece of one will overlap that of the other, thereby preventing all exposure of the end of the clothing, which being thus contained within the cap is not liable to be disintegrated.
I claim as my invention 1. The combination of a pipe and pipe-clothing with a cap, D, made in two parts for embracing both clothing and pipe, substantially as set forth.
2. The within-described cap for pipe-clothing, the same consisting of two parts, each composed of the semi-annular pieces d and e and connecting-piecef, and each part provided with lugs 27, all substantially as specified.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
