MICHAEL J. McI-IALE, OI SCBANTON, PENNSYLVANIA.

ADJUSTABLE EDGE-FLANGE.

Specification of Letters Patent.

Application filed December 22, 1915, Serial-1N0. 68,258: Renewed July 26, 1919. Serial No. 313,479.

To all whom it may concern:

Be it known that I, MICHAEL J. MoHALE, a citizen of the United States, residing at Scranton, in the county of Lackawanna and State of Pennsylvania, have invented certain new and useful Improvements in Adjustable Root Flanges, of which the following is a spec'ific.'tion.

My invention relates to new and useful improvements in an adjustable roof flange.

The primary object of the invention is the provision of a device of this character which may be adjusted to accommodate itself to pipes passing through the roof at various angles.

A further object of the invention is the provision of means for reversing the flange whereby a greater or less adjustment may be secured.

A still further object of the invention is the construction of the device in such a manner as to receive and securely hold a cal king with these and other objects in view the invention consists in the novel details of construction and arrangement of parts which will be more clearly understood from the following description and drawings, in which,

Figure 1 is. a longitudinal section through the roof and flange,

Fig. 2 is a longitudinal section through the roof showing aside elevation of the flange, and

Fig. 3 is an end view of the flange.

In the drawing the numeral 1 indicates a roof having an opening 2 therein through which a vent pipe 3 or other similar pipe may pass.

My adjustable roof flange is formed in two separate sections, one section forming the base adapted to be secured to the roof and. the other section being connected to the base and adjustable in relation thereto. The base and adjustable section are each struck from a single piece of material, in the pre ferred form of my invention, but it will be understood that the parts may be cast or otherwise constructed as may be desired.

In Fig. 1 of the drawing, I have illustrated my roof flange as applied to a flat roof in such a manner as to accommodate a pipe leading straight up through the roof and in dotted lines have shown the position in which the device may be adjusted.

The base comprises a flange portion indishown in dotted lines.

are secured to each side of the portion 5 and form pivot points for the adjustable section to be later described. By providing the openingin the portion 5 at an angle, it will be seen that one side or end of the base portion will be considerably higher than the other, and the purpose of which will be presently described.

The adjustable portion of my flange comprises av concavo-convex member so shaped asto fit the portion 5 of the base as is clearly shown in the drawing. The lower edge of this concavo-convex adjustable member is cut at an angle thereby forming one end thereof, as indicated at S, of less length than the opposite end indicated at 9. The upper end of the adjustable concavo-convcx member is flanged as indicated at 10 to receive a calking ring of lead or other suitopenings adapted to engage the rivets or.

lugs 7 formed on the base portion.

Having described the detailed construction of my device, it is thought that the operation and many advantages will be clearly understood. In Fig. 1 of the drawings as well as in Fig. 2, I have illustrated the flange as applied to a roof and greater or less adjustment can be secured by reversing the concavo-convex adjustable member upon the base. In Fig. 1 of the drawings I have shown the adjustable member in one position, and in Fig. 2 I have shown it reversed. lVhen in the position shown in Fig. 1 of the drawings, the adjustable member may be adjusted to the position illustrated in dotted lines and when in the position shown in Fig. 2, may be adjusted to the position in full lines or raised to the position It will be seen that when the adjustable member is reversed as illustrated in Fig. 2 of the drawings, a greater angle can be secured than when in the position shown in Fig. 1 of the drawings. It will be seen that when in the position shown in Fig. 2 of the drawings, the shorter end 8 of the adjustable member allows of a greater angle being secured. WVhen in raised position the end of the adjustable member will engage the lug or projection 6 formed on the portion 5 of the base. My adjustable roof flange is particularly adapted for earrying vent pipes through roofs which may be of a greater or less angle. It will be understood that the pipe will pass through the opening 2 formed in the roof and then through the opening formed in the portion 5 of the base as well as the opening formed in the adjustable member. After the pipe has been passed through the adjustable member, and calking rings 11 are secured to the flanged portion 10 on the adjustable member, the calking element or ring ll is then calked in and around the pipe. When it is desired to reverse the adjustable memher to secure a greater angle, it is only necessary to engage the flared ends of the lugs or projections 7 and they may be disengaged from the rivets or lugs 12.

Having fully described my invention what I claim as new and desire to secure by Letters Patent is:

1. An adjustable roof flange comprising a base, a cover movable of said base, and resilient means for removablysecuring said cover in position.

2. An adjustable roof flange comprising a base, a. concave-convex shaped cover movable of said base, and resilient means for removably securing said cover in position.

3. An adjustable roof flange comprising a base, a reversible cover movable of said base, and resilient means for removably securing said cover in either of its positions of operation.

4. An adjustable roof flange comprising a base, a reversible cover movable of said base, said cover having its wall concavoconvex in form and provided with an opening disposed at one side of the center thereof, and resilient means for removably securing said cover in either of its positions of operation.

5. An adjustable roof flange comprisin a base, a reversible cover movable of sai base, said base having its wall concavoconvex in form andprovided with an opening disposed at one side of the center thereof, oppositely disposed lugs carried by said base, and resilient ears formed with said cover and adapted to be snapped nto engagement with said lugs for pivotally retaining said cover in either of its operative positions.

6. An adjustable roof flange comprising a base, a reversible cover movable of said base, said cover having its wall ooncavoconvex in form and provided with a flanged opening disposed at one side of thecenter thereof, a gasket carried by the flanged wall of said opening, oppositely disposed lugs carried by said base, and resilient ears formed with said cover and adapted to be snapped into engagement with said lugs for pivotally retaining said cover in either of its operative positions.

7. An adjustable roof flange comprising a base, a reversible cover movable of said base, said cover having its wall concavo-convex in form andprovided with an opening at one side of the center thereof, a flange surrounding said opening, a gasket carried by said flange and having its inner wall flush with the exposed portion of the inner wall of said flange, oppositely disposed lugs carried by said base, and resilient ears formed with said cover and adapted to be snapped into engagement with said lugs for pivotally retaining said cover in either of its operative positions.

In testimony whereof I affix my signature in presence of two witnesses.
