Aug. 22, 1933. E. N. LIGHTBOW'N VENT PIPE JOINT GUARD Filed June 8, 1932 Patented Aug. 22, 1933 VENT PIPE JOINT GUARD Edward N. Lightbown, Brentwood, Md.
Application June 8, 1932. Serial No. 616,145
1 Claim.
This invention relates to vent pipes and has special reference to a vent pipe joint guard.
In the art of plumbing it is required, under most codes of plumbing laws, that each plumbing 5 fixture have a trap and that each trap be connected to a vent pipe extending through the roof of the building in which the fixture is located.'
In order to prevent leaks of rain water at the place where the vent pipe extends through the roof it is the practice to provide a flashing or flange having a sheet metal base which lies flat on and is secured in a leak proof manner to the roof. From this base there extends upwardly a tubular portion through which the vent pipe passes. Usualy this tubular portion is made of malleable metal such as lead or soft copper and it is, after being positioned, hammered or swedged into intimate contact with the exterior of the vent pipe. Due to various causes such as improper'or careless workmanship in forming the joint, the vibratory effects of winds, expansion and contraction from changes in temperature and the like, this joint between the vent pipe and flashing or flange is apt'to open so that rain runs down the vent pipe through the open joint and leaks into the house.
The principal object of the present invention is to provide a novel attachment for vent pipes joint with the flashing against all possibility of leaking, the device being of such'nature as to be very inexpensive and readily applicable to vent pipes either already installed or during installation.
With the above and other objects in view, as will be presently understood, the invention consists in general of certain novel details of construction hereinafter fully explained, illustrated in the accompanying drawing and specifically claimed.
In the accompanying drawing like characters of reference indicate like parts in the several views, and:
Figure 1 is a side elevation showing the device as applied to a vent pipe.
Figure 2 is a vertical section through the device, the tubular portion of the flashing or flange and the upper part of the vent pipe being also shown in section.
Figure 3 is a section on the line 33 of Figure 2, and
Figure 4 is a section on the line 4--4 of Figure 2.
In the embodiment of the invention as here shown the roof line is indicated at 10 and on the roof is applied a flashing or flange plate 11 having a centrally disposed tubular portion 12. The upper end 13 of this portion is fitted tightly, as by hammering or swedging, against the exterior of a vent pipe 14 which extends well up above the roof forming a guard which will completely protect the through this tubular portion 12. It is at this joint between the portion 13 and the vent pipe 14 that the leak is apt to develop.
The attachment itself consists of a metallic sleeve having a slightly tapered body 15 of suflicient length to extend from the top of the vent pipe to a point well below the upper end 13 of the tubular part of the flashing. Commonly the vent pipe extends about twelve inches above the end 13 and in such case the length of the body 15 would, preferably be about thirteen inches. An inturned cuff 16 is formed on the upper and smaller end of the body 15 and is spaced from the body so as to let the upper end of the vent pipe fit in the space, the cuff extending down a short distance, say a half inch, into the vent pipe. The upper end of the body is preferably about three-sixteenths of an inch larger than the diameter of the vent pipe while the lower end of the body is about seven-eighths of an inch more in diameter than said vent pipe. As the device is made the shape of the lower end is that shown by dotted lines in Figure 2 but when the device is applied to a vent pipe this lower end is hammered or swedged in against the part 13 as shown in full lines at 17 in said Figure 2. It is to be understood that the device is to be of suitable malleable metal or other suitabl material.
It will now be plain, from an inspection of th drawing, that there can be no possibility of a leak at the joint 13.
Obviously changes may be made in the form and proportions of the invention. For instance, the dimensions referred to may be varied to suit conditions and are not to be understood as restricting the invention to any particular size or proportion, the scope of the invention being understood to be limited only by the claims.
What is claimed is:-
A joint guard for the joint between a vent pipe and the tubular portion of its flashing and consisting of a tubular body member having a lengthsufiicient to extend from the top of the vent pipe to a point below the joint of the pipe and its flashing, and an inturned cuff formed on the upper end of the body and adapted to extend down into the top of the vent pipe, said body being tapered outwardly from the upper end downwardly to a point approximately on the level of the upper end of the flashing and having its lower end arranged to fit tightly against the outer surface of the tubular portion of the flashing. The lower end of the body being curvingly tapered inwardly to fit at its lower edge flat against said tubular portion of the flashing. V
