Description
March 11, 1930. F. J. MOORE ROOF FLASHING AND JACKET Filed Nov. 3, 1928 Patented Mar. 11, 1930 UNiTtEfi fiTATES FRANCIS J". MOORE, 0F MINNEAPOLIS, MINNESOTA ROOF FLASHING AND JACKET Application filed November 3, 1928. Serial No. 316,970.
My present invention relates to a combined roof flashing and jacket for a vent pipe or the like and is in the nature of an improvement on or a refinement of the invention disclosed and broadly claimed in my United States Letters Patent 1,279,572 issued September 24, 1918.
This roof jacket is circumferentially spaced from the vent pipe, to which it is applied, to leave an air space or chamber between said jacket and pipe. Said chamber has a closed top and an open lower end, the latter of which affords communication with the interior of the building through the roof structure for the passage of air therethrough to keep the air in the chamber at substantially the same temperature as that in the building to prevent formation of frost in the vent pipe by keeping the cold air outside of the building from coming into contact with said pipe.
The formation of frost in a vent pipe is,
of course, detrimental to the efficiency of said pipe for the reason that a cold vent pipe produces a poor draft and the conducting capacity thereof is often impaired by the building up of frost within said pipe.
In installing this roof jacket, the purpose for which said jacket is intended,is often destroyed by placing the roof structure against the vent pipe or in cutting a hole therethrough just large enough forthe vent pipe and thereby closing the interior of the jacket to the interior of the building so that the jacket simply forms a dead air space.
The object of my present invention is to provide the roof flashing and jacket with a spacer to prevent the instillation thereof without leaving or forming an opening in the roof structure that is spaced from the vent pipe to form a passageway between the interior of the building and jacket.
To the above end, generally stated, the invention consists of the novel devices and combinations of devices hereinafter described and defined in the claim.
The invention is illustrated in the single figure of the accompanying drawing wherein the view is partly in side elevation and partly in vertical section showing a roof structure and vent pipe extendlng therethrough and to ture is a flashing6 which extends under the shingles 3 and is nailed to the roof boards 2. Appliedto the flashing 6 is a jacket for the vent pipe 4 above the roof structure. This jacket comprises telescopically connected upper and lower sections 7 and 8, respectively, the latter of which at its lower end is rigidly secured to saidflashing by solder or otherwise. This flashing and jacket are of the type shown in the above identified patent and said flashing is readily adjustable to roofs of different pitch as fully described in said patent. By forming the jacket in two telescopically connected sections, said jacket may be readily longitudinally adjusted to vent pipes that project different distances above a roof.
A cap 9, of the type disclosed and claimed in my United States Letters Patent 1,647,414 issued November 1, 1927 and entitled Roof jacket, is applied to the top of the vent pipe 4 and upper end of the upper jacket section 7. It will be noted that the jacket is concentric with the vent pipe 4 and is spaced therefrom to leave an air chamber 10 between said jacket and vent pipe 4 and which chamber completely surrounds said pipe, is open at its lower end and extends through the flashing 6.
i A spacer 11 is provided to prevent the roof boards 2 from being closely positioned to the vent pipe 4 and thereby close the open lower end of the jacket and cuts off the warm air from the building to the chamber 10. This spacer 11, as shown, is in the form of a sleeve which forms a depending extension of the acket and also the air chamber 10. The upper end of the spacer 11 is telescoped into the lower jacket section 8 and rigidly secured in respect thereto by solder or otherwise. The length of the spacer 11 is such as to extend below the flashing 6 and through the hole 5 in the roof boards 2.
By providing the flashing and jacket with the s acer 11 it is impossible to place the roof oards 2 close enough to the vent pipe 4 to close the open lower end of the chamber 10. When installing the flashing and jacket after the roof boards 2 are in place, it is necessary to cut the hole 5 of such size as to permit the insertion of the spacer 11 therethrough.
The use of this spacer in connection with the roof flashing and acket aflords positive means to prevent the air chamber 10 from being closed by the roof structure. The spacer 11 is of substantially the same diameter as the acket and hence maintains an air space therethrough of the same size in cross section as the chamber 10 and the distance to which the spacer 11 extends below the flashing 6 depends on the thickness oi? the roof structure to which said flashing is applied. Or in other Words, the spacer must be of such length as to prevent the roof boards or other covering from closing the passageway from the building to the air chamber 10.
What I claim is:
The combination with a flashing having a raised intermediate portion, of a vent pipe jacket, the lower end of which is supported on said intermediate portion of the flashing and rigidly secured thereto, and a spacing sleeve telescoped into the jacket, extending through the raised intermediate portion of the flashing and below said flashing.
In testimony whereof I aflix my signature.
FRANCIS J. MOORE.
