Specification of Letters Iiatent. Ptqgnggd Sgpt, 10, 1918,

Application led October 18, 1917. Serial No. 197,342.

To all 'whom t may concern:

Be it known that I, EDWARD F. DONNELLY, a citizen of the United States, residing at Malden, county of Middlesex, State of Massachusetts, have invented an Improvement in Roof-F langes, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to roof flanges and has for its object to provide a novel roof flange which is simple in its construction and inexpensive to manufacture; which can be used equally well on a flat roof, a roof having a steep pitch, or a roof having any pitch between the two, and which has other advantages, all as will be more fully here- In order to give an understanding of my invention I have illustrated in the drawings a selected embodiment thereof which will now be described, after which the novel features will be pointed out in the appended claim.

Figures 1, 2 and 3 are longitudinal vertical sections through a roof flange embodying my invention showing the flange applied to roofs of different pitch;

Fig. 4 is a top plan view of.a roof flange with a portion of the flashing broken out;

Fig. 5 is a section on the line 5 5, Fig, 4.

My improved roof flange is formed with a bottom 1 adapted to rest on the roof 2 and it `has a wall or curb 3 rising from the bottom 1 and forming a space to receive the usual packing 4. This wall or curb 3 has a general oval shape and the

end portions

5 and 6 thereof are inclined in the same direction relative to the plane of the bottom 1. The curb 3 thus forms an oval space having its axis inclined to the bottom 1. The wall or curb 3 is situated a slight distance from the peripheral edge 7 of the bottom 1 so that a peripheral flange 8 is presented exterior to the wall 3. 9 is the usual copper flashing which encircles the wall 3 and rests on the flange 8, said flashing being preferably soldered to the flange S, as shown at 10, thereby making an absolutely tight joint.

The bottom 1 of the roof flange is provided with an opening 11 through which the soil pipe or other pipe 12 may be introduced. The opening 11 is herein shown as having a transverse diameter substantially equal to the distance between the sides 13 of the curb 3, and it has a longitudinal diy aineter which is considerably less than the distance between the

end portions

5 and 6 of the curb so that there are

portions

14 and 15 of the bottom 1 which are situated with# in the outline of the curb 3. These

portions

14 and 15 constitute supports for the oakuln or other packing 4 which is placed within the curb 3.around the pipe 12. They are also of a franoible nature so that they may be readily broken or chipped thereby to enlarge the longitudinal dimension of the aperture 11. This frangible character of the

bottom sections

14 and 15 may be secured in various ways. One way is to make these portions relatively thin, as shown in the drawings, so thaty they may be readily brolken or chipped by a hammer or other too The roof flange is made in the first place with the aperture 11 of sufficient size to easily receive the soil pipe 12 when the soil pipe extends through the bottom in a direction perpendicular thereto, as shown in Fig. 1, in which figure the device is illustrated as applied to a flat roof. When used in this way the roof flange is placed on the roof as usual and the soil pipe or other pipe is inserted through the aperture 11. The space between the pipe and the wall 3 is then packed with oakum or other suitable packing 4, and if desired hot lead 1'6 may be poured on top of the oakum to make a tight joint.

' If the roof flange is to be used on a roof having a relatively steep pitch, as shown in 4ig. 3, it will be necessary to have the aperture 11 enlarged somewhat in its longitudinal dimension to accommodate the pipe 12. This may be readily done by breaking away the edge of one or both of the

bottom sections

14 and 15. The shown as havin@ the greatest extent and the aperture 11 will preferably be enlarged by breaking away the edge 17 of the bottom section 15 in order to provide an aperture of sufficient size to receive the pipe 12. When the roof ange is used on a steep pitched roof, as shown in Fig. 3, it will be necessary to break away the edge 17 of the bottom portion 15 until the aperture is enlarged about to the dotted line 18, Fig. 4. After the roof flange has been placed on the roof, as shown in Fig. 3, the space between the pipe and curb 3 is packed with oakum bottom section 15 is or other' packing in usual manne* and the packing ma@v be sealed by the application ot melted lead to the top of the packing' it desired.

he device is equalliY applicable to a root having a less pitch7 as shown in Fig. 2, it onlyY being necessar)T to break away a less portion ot one or both bottom sections lei, l5 to accommodate the pipe. ln every instance, the bottom sections lil) 15 constitute supports Yfor the packing` and because the packing rests directly on the bottom it is not necessary to make the curb 3 of very great vertical dimension. rlfhe device is, therefore, a compact one which requires a relatively small amount oi metal in its inanu't'acture, a tact which reduces its cost.

claim:

A root flange haring a bottom provided throughout its extent with a latface to rest Copies o this patent may be obtained for on the root and also having a relativel)Y low oral-shaped Wall or eurb rising from the bottom a slight distance from its peripheral edge whereb;Y said edge of the bottom terms` a tlashinga'eeeiring iange on the exterior ot' the Wall, the end portions of said Wall or curb being inclined relative to the bottom., and said bottom extending irmardl;7 from the Wall or eurb and having a pipereceiving aperture therein, the portion of the bottom situated Within the outline of the Wall or curb constituting a support for the packing and being trangible so that it can be readily broken to enlarge the longitudinal dimension oit said aperture whereby the device may be used on either a fiat root or a pitched roof.

ln testimony whereof, l have signed my naine to this specification.
