PIPE-FLANGE COVER.
Specification of Letters Patent.
Patented Sept. 5, 1905.
Application filed November 29,1904. Serial No. 234.812.
[0 MN 'IIJiLO/lb 'lIb/ljl/ concern.-
Be it known that I, \VILLLUI A. T. WiL- 1 LINK, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Pipe-Flange Covers, of which the following is a specification.
My invention relates to pipe-flange covers. More specifically, it belongs to non-conducting jackets for pipe-joints, and has for its objects the production of such a cover having particular and peculiar construction and arrangement of parts, thereby reducing weight and cost of manufacture.
it is likewise an object of my invention to provide a pipe-flange cover having a drip-receiver and drip-cock for testing and draining purposes. 7
1 accomplish the objects mentioned above by fashioning and associating parts as illus trated in the accompanying drawings, of which Figure 1 represents an external side view of all parts assembled. Fig. 2 is a vertical longitudinal section. Fig. 3 is a vertical crosssection on line X X of Fig. l, and Fig. i is a vertical cross-section on line Y Y of Fig. 1.
Like numbers refer to like parts throughout.
In the drawings two portions of steam-piping having their flanges joining are designated by numerals l, and immediately about each portion of the pipe before the flanges are reached are plates 2, of asbestos packing or the like, bent into hollow semicylindrical form and held in similarly-bent sheets of metal 3, with ends a turned inwardly, as shown, and riveted to horizontal metal sheets or plates 5.
It will be observed from Fig. 2 that the total length of my invention comprises the combined lengths of the twin hollow half-cylinders of asbestos and metal just described and lying, it will be understood, upon the upper side of the steam-pipe and in addition the length of the space between the half-cylinders and in which the flanges or joint of the pipe situated. The outermost metal part of my invention is a sheet 6, bent into a halfcylinder and having outwardly-turned edges 7. riveted to the horizontal plates 5. Exteriorly sheet 6 is covered with a plate 8, of asbestos packing or equivalent substance. Upon each side of the middle air-space in which the pipe-flanges are located the inner and outer curved metal sheets 3 and (5 on the l same side of the steam-pipe are joined and held with relation to each other by suitable spacing rod-rivets 9.
It is thought to be now clear from an inspect-ion of Figs. 2 and 3 and from the preceding explanation that there are two curved metal sheets 3 joined to the outer curved metal sheets 6 and that their common axis of curvature is the axis of the steam-pipe. also that between the ends of sheets 3 there exists an air-space about the pipe flanges or joint extending outwardly to sheet 6. Upon sheets 3 and extending outwardly to sheet 6 are pairs of semicircular sheets of metal 10, having central half-circular recesses formed to fit sheets 3 exteriorly. The sheets 10 are held together at suitable distance apart by the spacing-rivets 11. (See Fig. 2.) By means of sheets 10 a stitf wall is formed at the right and left ends of the invention (see Fig. 2) for the externally-placed semicircular plates of asbestos packing 12.
In Fig. 2 there are shown attached to the inner surface of the innermost metal semicircles 10 two curved parallel strips 13, between which is inserted the edge of the curved perforated sheet 14. This sheet H completes the upper half of my invention, and as all parts are attached to or carried by the hori* zontal plate 5 it now becomes apparent that the horizontal plate and everything comprising the upper half of the invention may be removed from pipe 1 or placed thereon togcther.
The lower one-half of my invention that is to say, the half below the pipe is an exact duplicate of the upper half, with the addition of the drip-receiver l5 and drip-cock l6. (Shown in Fig. +15.) The drip-receiver consists of a sheet of metal having the form shown usually, although .I. do not limit myself to any ptll'blcllitll shape for that part. It is placed beneath the perforated sheet 1*, and its middle and lowest point touches the outer metal sheet 6, at which point the drip-cock is connected.
In operation when the two halves are placed together on pipe 1 the two horizontal sheets 5 have their projecting ends scparably secured together bysmall bolts 17. The middle openings 18 of sheets (see Fig. 3) have the same length and width as the air-space about the flanges. The perforated sheets by breaking the air-space limit the convective loss of heat from the pipe-flanges; butany leakage passes down through them and is guided by the dripreceiver 15 into the drip-cock, and the existence of a leak is determined by occasionally turning the cock.
In practice my invention is covered externally with canvas 19in the ordinary way.
Having thus described my invention and its mode of operation, what I claim is- 1. In a pipe-flange cover, the combination with separable horizontal plates 5, of inner curved sheets of metal and packing adapted to fit on a pipe and having an air-space between their ends for the flanges of a pipe, an outer curved metal sheet, and spacing means securing said inner and outer metal sheets together, a sheet of packing upon said outer metal sheet, pairs of semicircular recessed metal sheets arranged between said inner and outer metal sheets, and external semicircles of packing forming the ends of the flange-cover, substantially as described.
2. In a pipe-flange cover, the combination with separable horizontal plates 5, of inner curved sheets of metal and packing adapted to fit on a pipe and having an air-space between their ends for the flanges of a pipe, an outer curved metal sheet, and spacing means securing said inner and outer metal sheets together, a sheet of packing upon said outer metal sheet, pairs of semicircular recessed metal sheets arranged between said inner and outer metal sheets, perforated curved sheets arranged between said pairs of sheets, and external semicircles of packing forming the ends of the flange-cover, substantially as described.
3. A pipe-flange cover comprising two complementary portions having in combination with curved inner sheets conforming to the shape of the pipe adjacent to its meeting flanges, exterior curved sheets and radially spaces are provided at the sides of said middle space, and means adapted to secure the said complementary portions of the cover one to the other.
4. A pipe-flange cover comprising two complementary portions having in combination with curved inner sheets conforming to the shape of the pipe adjacent to its meeting flanges, exterior curved sheets and radiallydisposed spacing-rivets connecting the inner and outer sheets, pairs of semicircular sheets arranged between the said inner and outer curved sheets and horizontal spacing-rivets connecting the members of each of said pairs of semicircular sheets whereby a middle space is formed to receive the pipe-flanges and airspaces are provided at the sides of said middle space, curved perforated sheets arranged between the said pairs ofsemicircular sheets, and means adapted to secure the said complementary portions of the cover one to the other.
5. A pipe-fl ange cover comprising two complementary portions having in combination with curved inner sheets conforming to the shape of the pipe adjacent to its meeting flanges, exterior curved sheets and radiallydisposed spacing-rivets connecting the inner and outer sheets, pairs of semicircular sheets arranged between the said inner and outer curved sheets and horizontal spacing-rivets connecting the members of each of said pairs of semicircular sheets whereby a middle space is formed to receive the pipe-flanges and airspaces are provided at the sides of said middle space, means adapted to secure the said complementary portions of the cover one to the other, and a drip-cock communicating with the said middle space of one of the portions for draining the interior.
In testimony whereof I afiix my signature in presence of two witnesses.
