Specification of Letters Patent.

Patented Nov. 18, 1919.

Application filed April 26, 1919. Serial No. 252,780.

To all whom it may concern:

Be it known that I, MAURICE A. NEAMES, a citizen of the United States, and a resident of Gramercy, parish of St. James, State of Louisiana, have inventedcertain new and useful Improvements in Protective Coverings or Casings for Pipes, of which the following is a specification.

My invention relates to a protective covering or casing for pipes, conduits, mains and for fire-proofing of building columns and the like; and, more particularly, to a covering or casing for pipes, conduits and mains exposed to deteriorating influences, such, for example, as extreme heat, moisture, acids and gases.

The object of my invention is to protect pipes, conduits, mains and other pipe installations from the deteriorating action of high heat, moisture, gases and acids by means of a two section protective covering or casing with novel clamping and supporting features, the whole being extremely simple in design and construction, quickly and with the greatest facility adjustable in place over the piping wherever installed, and which may be manufactured with a minimum of operations and at correspondingly low cost.

The invention itself consists of the novel features of design and construction in the various applications of the preferred embodiment thereof illustrated in the accompanying drawings, in which similar characters of reference indicate corresponding parts throughout the several views, and in which Figure 1 is a side view of the pipe construction applied to an elbow connection, taken on a verticalplane passing through the longitudinal aXis of the case, the incased pipe being shown in full outline.

Fig. 2 is an end view of the pipe protector construction showing the casing in full outline and illustrating the end clamping and supporting means.

Fig. 3 is a side view in elevation of my protective covering applied to a- T connection, taken on a vertical plane passing through the longitudinal axis of the casing, the pipe being shown in full outline.

Fig. 4- illustrates in plan View, partly in section, the method of applying a plurality of sections of my protective covering end to end on a straight run of pipe.

Fig. 5 is a side view in elevation of the metal clamp and fastening means by which supported on the Referring to the drawings, the invention casing 7, molded of refractory tile or other suitable material to meet special require ments. The casing 7 is composed of two like half sections 8 and 9, in Fig. 2 shown joined to ether and may be made from the same mold.

The casing 7 is shown in F 1 and 2 shaped to fit an elbow union between vertical and horizontal pipes 18 and 1? respectively; in F ig. 3 a style casing is illustrated suitable for a T connection between vertical and horizontal pipes 18 and 17 respectively, and in Fig. 4 the casing 7 is shown applied to a straight run of pipe, a plurality of sections being positioned end to end. scription of the casing'l, given in the following for the elbow connection shown in Figs. 1 and 2, will also serve to describe the modified forms thereof illustrated for the T connection and straight run of pipe, Figs. 3 and 4 respectively, as the details of construction in each are the same.

Each of the longitudinal half sections 8 and 9 of the casing 7 is molded with interior and end recesses, which, when the sections are fitted together, form interior cavity-lO and end cavities 11 and 12. Cavity 10 serves both to reduce the weight of the construction and to furnish a dead air space necessary, for example, when the covering is used as a protection for the blow off pipe of a boiler. End cavities 11 and 12 are formed by the end recesses of the sections 8 and 9 when brought together, and these cavities are so shaped, and are of such dimensions laterally and in depth, that they will each receive themetal clamping and supporting members 13, which, when in position on the pipes and in said end cavities, serve to lock the sections 8 and 9 together composing the casing 7, and to secure the casing to the pipes.

The metal clamping and supporting member 13 is made up of two like half sections 13 and 13 in Fig. 5 shown joined in horizontal axial plane 20, each half section carrying like male and female dovetailing 14 and 15 for locking the sections together. Sections 13 and 13 are identical and may be cast from the same pattern, and are hence in vertical axial plane 19,'

its preferred form comprises a sectional The deinterchangeable and easily matched for assembly. A central opening 16 in the clamp 13, and lengthwise thereof, is provided, the diameter of said opening being such that the clamp may be closely fitted over the pipe to be covered.

The ends and the longitudinal seams of the case 7 are covered with cement, clay or other suitable material, thus sealing the casing with the clamps and supporting mem bers completely covered and embedded therein, rendering them free from external deteriorating influences.

It will be noted that the cross section of the casing 7, shown in Fig.2, is made oval in shape, the object of which is to reduce the weight of the construction; and, further, when the casing is applied to a boiler blow off pipe, the oval cross section will present as small a surface to the backward flow of furnace gases as possible, thus affording a freer egress to the gases than where a brick casing 1s employed.

Having thus described my invention, I claim as new and desire to secure by Letters Patent.

1. A protective covering or casing for a pipe of the class described, comprising, in combination, a sectional unit of refractory or protective material, an end cavity in said unit, and means for locking the sections of said unit together and for supporting the said unit on the pipe comprising a member fitting into said end cavity, said member being provided with a central opening of dimensions to fit the exterior of the pipe.

2. A protective covering or casing for a pipe of the class described, comprising, in combination, a two section unit of refrac tory material, an end cavity in said unit, and means for locking the sections of said. unit together and for supporting said uniton the pipe, said means comprising a two section member fitting into said end cavity, said member being provided with a central opening of dimensions to fit the exterior of the pipe.

3. A protective covering or casing for a pipe of the class described, comprising, in combination, a two section unit of refractory material, end cavities in said unit, and means for locking the sections of said unit together and for supporting said sections on the pipe, said means comprising a plurality of two section members fitting into said end cavities, said members each being provided with a central opening of dimensions to fit the exterior of the pipe, and interengaging means for locking the sections of said members together.
