,SOIL-PIPE AND ROOF CONNECTION.

SPECIFICATION forming part of Letters Patent No. 621,320, dated March 21, 1899.

Application filed December 3, 1897. Serial No. 660,701. (No model.)

Aing a weatherproof joint between the roofing of houses or buildings and the soil pipe, stack,

or other flue providing an escape or vent, and which will obviate a molten, putty, or like joint, and which will not be affected by contraction and expansion and fulfil the requirements presently to be referred to..

Certain requirements provide that the projecting portion of the soil pipe or stack above the roof shall be of larger diameter than the inner or main portion, and to meet these conditions different sizes of pipe are generally employed and require a molten or like joint between them. A purpose of this invention is to have the inner and outer portions of the pipe of different diameters and integrallyT formed, thereby obviating the' necessity for the usual joint and simplifying the construction and materially reducing the cost. The lower portion of the enlarged section of the pipe encircles the upper portion of the smaller section and overlaps the upper end of the roof-flanges, which latter is snugly received into the space surrounded by the depending portion of the upper or enlarged section, as will be describedat length farther on.

For a full understanding of the merits and -advantages of the invention reference is to be had to the accompanying drawings and the following description.

The improvement is susceptible of various changes in the form, proportion, and the Vminor details of construction without departing from the principle or sacrificing any of the advantages thereof, and to a full disclosure of the invention an adaptation thereof is shown in the accompanying drawings, in which- Figure lis an elevation of the upper length of a soil pipe, stack, or flue constructed in accordance with this invention, showing it inA operative relation. Fig. 2 is a vertical centrai section. Fig. 3 is a detail section thereof, on a larger scale, and disassociated from the roof-liange and other parts.

Corresponding and like parts are referred to in the following description and indicated in the several views of the drawings by the same reference characters.

The pipe, stack, or flue is composed of parts l and 2, the part l being of larger diameter than the part 2 and being the upper or outer element. rPhe part 2 is the inner or lower element because it does not project beyond the roof 3 and is of less diameter than the upper part l. These parts 1 and 2 are inte grally formed, and the lower portion of the outer part l surrounds the upper or contiguous portion of the part 2, inclosing a space 4, which receives the upper end of the roofiange 5, the latter being of ordinary construe-- tion and having'its base secured to the sheathing and overlapped by the shingles or slates in the usual manner. The pendent portion 6 surrounds the roof-flange 5 at its upper end and excludes rain and provides a weather'- tight joint without requiring the use of putty,

calking, or other material, and the parts can contract and expand without danger of starting or opening seams and causing leaks. The upper part 1 lnay be suitably ornamented, thereby giving a nished appearance to the projecting portion of the pipe.

The base of the roof-ange may be straight or angling, according to the pitch of the roof, and in metal5 roofing it may be a collar soldered at its lower end to the metal covering. This pipe does not require any special fitting to the roof and can be placed in position by the carpenter, tinner, or roofer, thereby obviating the necessity for the plumber to go upon the roof when placing the soil pipe or stack in position.

At this point it is to be observed that the space confined between the pendent dan-ge 6 and the lower pipe-section 2 is formed by providing the upper end of said lower pipe-section with an upwardly -inclined and outwardly-deflected web, which is joined to the larger pipe-section 1 near the lower end of the latter, and by reason of having the said web upwardly inclined and disposed adjacent the roof-flange 5 is permitted to snugly em- ICO brace the lower pipe-section 2 and also to have its upper end rest against the said inclined outwardly-deflected web, thereby insuringa proper support of the soil-pipe on the roof -ange and a thoroughly weather-tight connection between these parts.

Having thus described the invention, what is claimed as new isl. A soil-pipe having separate upper and lower concentric sections, respectively, of different diameters, and the lower section provided at its upper end with an upwardly-inelined and outwardly-deflected Web joined to the larger upper pipe-section near the lower end of the latter` and forming an intervening space between the contiguous ends of the two sections, said lower pipe-section being adapted to snugly register within a roof-lian ge, and the Aintervening space between said sections permitting the roof-fiange to extend to a point with its upper end resting against said deected web, substantially as described. g

2. In a soil pipe, stack or Iiue, a length comprising upper and lower parts integrally formed and of diierent diameters, the upper part being the larger and having its lower portion surrounding the upper portion of the lower part and forming a space to receive the upper end of a roof-flange, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto aiixed my signature in the presence of two witnesses.

JAMES W. BROWN.
