GEORGE B. WIESTLING, OF MOUNT ALTO, PENNSYLVANIA.
IMPROVEMENT IN LAGGING FOR COVERING STEAM-PIPES.
Specification forming part of Letters Patent N o. 192,474, dated J une 26, 1877 application iled April 23, 1877.
To all whom t may concern:
Be it known that I, GEORGE B. WIEsT- LING, of Mount Alto, in the county of Franklin and State of Pennsylvania, have invented a new and Improved Lagging, of which the following is a specification:
Figure 1 is a side elevation of a section of pipe covered with my improved lagging. Fig. 2 is an enlarged transverse section, taken on line :o in Fig. l.
Similar letters of reference indicate corresponding parts.
My invention relates to lagging or covering to be applied to pipes and boilers to prevent the radiation of heat; and it consists of an envelope of one or two thicknesses of ordinary strawboard separated from the surface of the boiler or pipe, as hereinafter described.
In the drawing, A is a pipe, which may represent any steam-heated surface to be protected by the lagging. B B, Ste., are strips of Wood, which may be of any desired width and thickness, and are arranged a small distance apart'around the pipe A, C is a covering that consists of one or more thicknesses of straw-board Wrapped around the strips B inclosing the air-spaces a. Another form of lagging is shown at the opposite end of the tube A, which consists of a straw rope, D, Wound around the pipe and covered with sheets of strawboard, as in the other case.
The coils ofthe rope are placed a small distance apart, and the covering C, when placed around the rope D, incloses air-spaces, which, together with the rope, prevents the radiation of heat from the pipe. The strips B, as Well as the straw-board covering' B, may be retained in place by cords or Wires.
The lagging may be applied with advantage to Waterfpipes to prevent freezing.
The advantages ot' this covering over others now in use are its cheapness, its adaptability
