IMPROVEMENT IN THE APPLICATlON OF STEAM-'PIPES TO BUILDlNGS.

Specification forming part of Letters Patent No. GILNN), dated June 22, 1375 application tiled April 23, 1875.

To all whom it may concern:

Beit known that I, OALEB C. W'ALwonrn,

of Massachusetts, haveinvented a new and uset'ul Improvement in the Application of declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, and vto the letters of reference marked thereon, which form a part of this specification. A

In the ordinary application of steampipes to buildings,when the same are carried through through the ceiling and iloor of each story, through which the pipe is to be carried, such hole being of much larger diameter than the pipe. Into this hole is inserted a tin tubular guard, ot a larger diameter than the steampipe to be carried through the same, and of sufficient size to allow currents of cold air to pass up between the two, such guard at its upper end being turned down upon and nailed lower end being untlanged, and extending down through the ceiling a distance equal to the thickness of the plasterin g. Through this guard the steam-pipe is carried.

This application of the steam-pipe to the building is objectionable on several accoun ts,I as the space between the pipe and theguard for the ascent of currents ot' cool air not only allows any impure air, smoke, disagreeable odor or noise contained or generated in a room to ascend into the room above it, but it affords a passage-way for bugs, roaches, 85e., to migrate from one room to another. It also affords a very imperfect barrier against unduly heating or charring of the woodwork in the immediate vicinity of the pipe.

To remedy these objections is the object of my invention, which consists in surrounding the steam-pipe with one or more capped sleeves space between suoli and the steam-pipe with asbestus or other non-combustible material, whereby not only a perfect protection against undue heating ofthe wood is attained, but the passage of noise, disagreeable odors, smoke,

&c., from one room to another is colnpletely obviated, the same being as will be hereinafter referred to and claimed.

In the drawing I have illustrated my invention under two forms, one in which the steampipe is untapped, a single sleeve or packingchamber being employed, and the other in which a branch pipe is led from the steampipe, and in which two sleeves or packingchambers are employed.

ln the said drawing, Figure 1 denotes a central and vertical section of my invention as applied to a ceiling and oor above it, in accordance with the rst part of my invention. Fig. 2 is a similar section ot' my invention as applied to a ceiling and i'loor above it, illustrating the second part of my invention. i Figs. 3 and 4 are, respectively, top views ot' the capplates of Figs. l and 2. Y

In the drawing, A may be supposed to represent a floor of a building; B, one ot` the t'urring-boards, and C the ceiling or plastering. D is the steam pipe.

In Fig. l, a denotes a hollow cylinder or sleeve, the same being disposed concentrically around the pipe D, such sleeve being made ot such diameter as to leave a free space between the two, so as to constitute a packing-chainber. b is apap-plate having a hole through it, having a diameter sutticient to receive and closely tit to the pipe l). Snehcap-plate has an annular flange, c, on its under face to enter the chamber or end of the cylinder, such plate being secured to the top of the door by means of screws passing through the plate and into the'tloor. d is a short cylindrical tube, which has an annular ilange, e, project ing from its upper end, the same being aiiixed by means of screws to the under face of the t'urring B. The upper end of this tube eX- tends up into the lower end of the cylinder, while its lower end projects down below the furring a distance equal to the thickness of the plastering C. f is a screw-cap, embracing thesteam-pipe and screwing into the bottom ofthe tube d, the said cap having an annular flange, g, upon its lowerend, which screws up against the plastering, and serves to hold the same in place and make a tight joint therewith. The space between the steam-pipe and its enveloping-tube c is to be packed with asbestus or other elastic non-combustible packing.

In Fig. 2, h denotes a hollow tube, which embraces the upper portion of the steam-pipe D, and is of a diameter somewhat larger than the pipe, the upper end ot' the tube being hanged and secured by means ot' screws to the top of the hoor A. The bottom ofthis tube or sleeve is formed with a contracted neck, and has a hole made through it of the size of the steam-pipe D. z' is another screwcap, having a hole made axially through it of a diameter corresponding` with that of the steam-pipe, such latter cap screwing into the upper end of the sleeve It; or, it' preferable, the latter cap may be screwed to the iiange of the sleeve 7L. By this construction ot' the tube h a packing-chamber is produced which is to be ijlled with asbestus or other elastic heatresisting packing. h is another hollow sleeve or tube, which is disposed below the sleeve h, and concentrically around the steam-pi pe, such sleeves being of such a length as to leave a portion of the steam-pipe exposed between the two, the object of this arrangement being to allow the steam-pipe to be tapped to receive a branch pipe. The tube h is formed with an annular dan ge, j, near its lower end, by whichthe tube is secured by means of screws to the under surface of the furring B, such tube extending a little below the ange, or a distance equal to the. thickness of the ceiling or plastering. A screw-cap, l, screws into the lower end of the said tube, and impinges against the outer surface of the plastering. The upper end of this tube or sleeve is contracted, and has a diameter corresponding with the diameter of the-steam-pipe. By this means a chamber isformed in the sleeve IL', which, like the sleeve h, is to be filled with asbestus or equivalent elastic heat-resisting packing. m is a branch pipe leading'from the main steampipe, the same being tapped into the latter between the sleeves h and la'.

Havingdescribed my invention, what I claim 1s- 1. The combination, with a steam-pipe passing up through a ceiling and contiguous door ot' a building, ot' a protecting-sleeve, packed as described, and having each ot' its ends provided with a flanged fastening-cap, the lower one having a screw-cap, g, screwing into its inferior end and against the plastering, the whole being constructed and applied in manner as shown, and for the purpose set forth.

2. The combination, with a steam-pipe passing up through a ceiling and a contiguous floor of a building, of a sectional sleeve or two sleeves, each provided with a packing-chamber and packed as described, the upper one of such sleeves being provided with a fasteningflange and a screw-cap, and the lower one having a fastening-flange and a screw-cap to screw into the inferior end of the sleeve and against the outer face of the plastering, the whole being substantially as and for the purpose set forth.

3. The combination, with a steam-conducting pipe, of a circumscribing sleeve packed with asbestus or other non-combustible material, such packing impinging against the pipe, and filling the space between the latter and the sleeve, as and for the purpose set forth.

4.-' Ihe combination with a steam-pipe, D, of the tube or thimble d, provided with a flange, e, and the screw-cap f, provided with a ange, g, the said i'lan ges being, respectively, applied to the under surface of the furring and the lower face of the plastering, substantially as shown and described.

In testimony that I claim the foregoing as my own .invention I afiix my signature in presence of two Witnesses.
