ROOF CONNECTION.

Specification of Letters Patent.

Patented Nov. 18, 1919.

To all whom t may concern Be it known that I, CI-IARLEs L. Hom', a citizen of the United States, and a resident of Lawrence, county of'EsseX, State of Massachusetts, have invented an Improvement in Roof Connections, vof which Jche following is a specification.

rlhis inventionparticularly relates to connections for internal drainage to the surfaces of what are known as saw-tooth roofs, which consist of a series off oppositely inclined roof sections formingv a series of valleys, the section forming one side of each valley being nearly vertical and principally of glass and the, sections forming the other side being inclined at angles usually from 200 to 330 and being formed of plank or cement, covered with water proofing material.

Roofs of this character are frequently of1 large area, so that the length of each valley` is so great that provision for drainage at intervals throughout the length of each valley must be made.

As usually constructed, roofs of this character are provided with girde-rs which extend continuously throughout the length of each valley at the bottom thereof, to provide a support for the ends of the roof beams or timbers.

These girders are usually supported by upright posts arranged at. suitable intervals, and, where a Wooden beam or timber is employed to support the roof timbers, usually an iron Ibeamis provided between the timber and the posts.

, Inasmuch as the location of the roof drain in the middle of the lowest portion ofl the valley would make it necessary to weaken the roof supports to a highly objectionable extent, suoli anarrangement is notk considered practicable, and, to avoid this difliculty, it has been common practice to build up clined roof section, thereby permittingthe roof drain to be-set in the portion" which extendsover the inclined roof section, sothat' the drain pipelmay passdownward;l at. one

Y be' secured',4 and. to provide means whereby.

side ef the iniddlegirdeny This arrangement isobjectionable onaccount of the excessive expense of filling up the valley to the necessary extent and it is particularly objectionable on account of the fact that, in order to get the necessary slope in the bottom of the valley to the drain, it is necessary to build the cricket much higher at the points midway between the outlets than at the outlets, so much so that it ofte-n becomes necessary to fill in up to the sash level, or undesirably close to the glass of the upright section.

Thile these objections may be largely, and I believe entirely, obviated by arranging the outlet fitting in the inclined roof section as closely as possible to the middle supports, certain other difficulties are encountered in thus arranging the outlet fitting, and it is these difficulties which it is the primary object of my invention to overcome.

Some of these difficulties are due to the fact that the angle of inclination of the inclined roof sections are likely to be different with diderent buildings, so that a fitting which is adapted for one inclination will not be suitable for another. Much complication and expense may, therefore, be saver by the employment of a fitting which is adaptable for roofs of all inclinations, so that the production of such a. fitting is one of the objects of my invention.

A further object ofmy invention is to provide a form ofV roof fitting adapted tol be located in the inclined roof section of' the valley which will provide a large, ef-

Y fective area for the ingress of water to the drain pipe withoutv unduly enlarging the roof aperture, so that the water flowing info the valley will be conducted to the drain pipe before it can rise to an undesirable extent inthe valley.

Another object of my invention is to provide a form of fitting for use' in the above' specified location which isY but slightly, if any, greater than that involved in installing a connection for an ordinaryflat roof,

`Other objects are to provide the fitting withl means wherebyit may be locked` to roof sectionsk of different inclinations, so that, by employingy a slip jointv in the pipe to whichy it is connected. the advantages of a roof connection, such as that broadly claimed in myprior Patent #1059671, may

connection between the fitting, at whatevel` inclination it may be positioned, and a ver; tical drain pipe, may be readily made.

I accomplish these objects by the means shown in the accompanying drawings in which:

Fig. 10 is side elevation of the fitting, showing adjustments to roof sections of different inclinations.

In Fig. 1 of the drawing a portion of a valley in a saw-toothed roof is shown, which comprises the nearly vertical roof section 10, composed principally of glass, the inclined section 11, which is shown as an ordinary planked roof supported by roof timbers, which are usually supported in stir rups on a main timber, as 12, the latter being supported by iron I-beam, as 13, mounted on upwrightposts, as 14.

According to my invention, I provide a roof fitting 16, which is of tubular form and of sufiicient length to extend completely through any roof to which it is likely to be applied, said fitting being elliptical in form at its upper end and tapering to a circular form at its lower end, a preferable arrange ment being such that the internal crosssectional area at the upper endis approximately double that at the lower end, for reasons to be explained. Said fitting is provided with a flange 16a which extends about both ends and one side of the elliptical opening, the flange being reduced to nothing at the middle of the opposite side, indicated by the character X, Fig. 6. In practice the angle of inclination of the inclined roof sec tions, corresponding to the section 11, vary from approximately 20O to 330 from the horizontal, and, according to my invention, the fitting 1G is so constructed that the angle between what I may term as its front side, which comes next the timber 12, and the plane of the fiange 16a, exceeds a right angle by the minimum angle at which the inclined roof section is likely to be built, namely,

approximatelyv 2Go, while the surface at thelower end of the fitting is preferably formed at an angle to said front side which exceeds a right angle by the mean roof angle, for example 6. The fitting is also provided with side ribs 16", which extends from nothing, at points adjacent the under-side of the flange, to the lower end of the fitting, the edges of said flanges being parallel, as shown in Fig. 5. The lower end of the fitting is provided with bosses 16, having dove-tailed slots formed in their under sides, which are adapted to receive the heads of clamping bolts, 18, as shown in Fig. 4.

An elliptically shaped, fianged clamping collar 20, is provided, which is adapted to fit loosely on the exterior of the fitting 16 in as close proximity thereto as would be required by a roof of minimum thickness, said collar being provided with a pair of set screws 21 disposed at opposite ends of its long diameter, in position to engage the edges of the ribs 16", to clamp the collar to the fitting, and a wedge 22 is provided` which is adapted to be driven in between the collar and the fitting at the rear side of the latter.

In setting the fitting into position, an elliptically shaped opening is eut through the roof section 11, which corresponds as closely as possible to the exterior of the fitting adjacent its flange, in such a position that its long diameter extends in the direction of the timber 12, so that the timber forms the lower side of the roof opening at the middle thereof. lVhen the fitting is placed in position in the roof, it will be suspended by its flange, and its front side, at the point X, will rest against the timber 12, as shown in Figs. 1 and 6. The fitting is then locked to the roof by forcing the collar 20 against the under side of the roof, and by locking it in position by means of the set screws 21 and wedge 22, as before described.

The fitting will thus be held in a certain angular position with relation to the vertical, dependent on the inclination of the roof surface in which it is placed. That is, with the above described construction, the fitting may be considered as adjustable to different angular positions, dependent on the inclination of the roof, the point X as a pivotal point, from an initial position, corresponding to a roof of minimum pitch, in which the side of the fitting rests against the timber 12, throughout its entire length, and a position in which the angle between the timber and the adjacent side of the fitting is equal to the difference between the angle of a roof of minimum pitch and that of a roof of maximum pitch, as illustrated by the dotted and full line positions of Fig. 10.

In completing the connection of the fitting to the roof surface, a copper flashing 24, having an aperture, corresponding to the tting orifice, is placed in position on the.

neas-1,189?

flangev 16s, said flashing being. adapted to extend beyond the flange 1,6?L onto :the roof. surface and'ontc the surface of the timber.

gravel roof covering 26 being indicated,

which brings the roofsurface up to the level of the gravel stop 25a, both on the roof section 11 and on the'timber 12.

In practice, the roof'. covering directly over. the timber. is gradually increased inl thickness in each direction from the middlev of the fitting, so that the' bottom of the valley will be inclinedito each fitting, from each side, from points niidway between eac-h fitting, `as indicated in Fig. 2.

In making the connection between the lower end of the fitting and the drain pipe, a smooth surfaced brass tube 28 is provided, to one end of-which a flanged ring 29 is rigidly connected, and a coupling ring 30 is passed onto said tube into engagement with said ring 29. The surface of the flanged ring 29 is inclined or disposed in a plane inclined to the axial line thereof, and a wedge-shaped lead washer 3l is also provided, and adapted to be interposed between the lower end of the fitting and the ring 29. By rotatably adjusting both the washer 3l and the tube 28, the latter may be held in a vertical position, with the several engaging surfaces in flat contact, and when thus adjusted, the bolts 18 are suspended in the dove-tailed slots of the fitting and passed through the ring 30 and the nuts are screwed thereon, so as to force said surfaces into water-tight engagement, as indicated in Figs. l, 2 and 4.

A pipe sec-tion 32, having a stuffing box 33 at one end, is telescopically engaged with the tube 28, and the opposite end of said section is connected to the drain pipe line 3st by a suitable off-set connection 35, which may be set in different positions according to the distance of the pipe 32 from the line of the drain pipes.

With the above described construction, any appreciable quantity of water which accumulates in the valley will immediately flow over the lower edge of the fitting and be conducted away by the drain pipe, and, as the opening thereto is substantially longer than wide, substantial accumulation of the water in the valley will be prevented, so that the water will not rise against the glass l0 to an objectionable extent.

As the drain pipe is of a size sufficient to conduct away all the water which would be supplied under ordinary conditions, the water level in the valley is not likely to reach a point in which moi'e than lia-'lf the inlet orifice will be covered.'

Theabove described constructionmay be readily adapted toa roofi section of any pitch within ordinary limits without change inconstruction, the only necessity being to bend the front portion of the flashing to correspond to the angle between the inclined roof surface and the surface ofthe middle timber, and to make the necessary adjust-y ments ofthe parts, as already described.
