UNITED STATES PATENT OFFICE.
E. O. LITTLE, OF ST. LOUIS, MISSOURI, ASSIGNOR TO EVELINE LITTLE, OF THE SAME PLAGE.
|MPROVED oovERlNc FOR STEAM PlPEs AND I2o|| |ERs.-`A
Specification forming part of Letters Patent N o. 56,856, dated July 3l, 1866.
To all whom it may concern:
Be it known that I, E. C. LITTLE, of St. Louis, in the county of St. Louis and State of Missouri, have invented 'a new and useful Improvement in Coverings for Steam Pipes and Boilers; and I do hereby declare that the following is a full, clear, and exact description thereof', which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part oi' this specification, in which- 'Figure 1 is a longitudinal section of a steampipe covered. Fig. 2 is a cross-section of the same.
Similar letters of reference indicate like parts.
The nature of this invention consists in preventing the radiation and loss of heat from steam pipes and boilers by covering them with a coating of plaster-of-paris cement, which may be used with a wrapper, to vguard against accidental injury to the plaster, or not, according to circumstances.
The ordinary method of covering steam pipes and boilers (to retain the heat) with felting, blanketing, and other materials is not nearly so effectual as plaster-of-paris, which is a superior non-conductor of heat, while they are good conductors. This substance, too, is very abundant and cheap and is easily applied, while it lasts a long time without needing repairs or renewal.
The blue color in the drawingsI indicates a steam-pipe, a, overlaid evenly with plaster-ofparis, b, to the depth of, say, one-third to half an inch for an inch pipe, and indicated in white between the metal pipe and a wrapper of canvas, c, indicated in yellow.
The plaster-of-paris is applied to the steampipe in a uid condition, and may be run into a mold or form surrounding the pipe, or be put on with a trowel or other suitable tool when convenient, and afterward wrapped with canvas or other suitable fabric to keep the plaster in place. When applied to boilers, segmentary bricks or blocks of plaster-of-paris to t the shell ofthe boiler may be used, and the interstices be filled with Huid plaster, and in this case a wrapper is not necessary.
Having described the composition and application of my improvement, what I claim as new, and desire to secure by Letters Patent, 1s-
Oovering steam pipes and boilers with a coatingofplaster-of-paris cement, with or without a wrapping of canvas, for the purpose of retaining the heat and preventing its loss by radiation, in the manner herein described.
E. C. LITTLE.
