UNITED STATES PATENT OFFICE.

ROOF FLASHING.

Application filed November 5, 1926.

This invention relates to roof flashings, adapted to maintain water-tight joints between a roof and a pipe, such as a ventilating pipe, for example, projecting upwardly therethrough.

Such devices commonly comprise a flat base plate which is anchored in or upon the roof materials, and a sleeve member projecting upwardly from the base, the free end of the sleeve snugly surrounding the pipe and being calked or otherwise secured thereto to maintain a tight joint. is usually supported from below, independently of the roof, and if the roof should settle an appreciable amount as it often does in time or tilts slightly in one direction or another, the joint between the sleeve and the pipe will be broken away and leakage will occur.

The principal object of the present invention is to provide an improved roof flashing which will permit limited relative movements in various directions between the roof and pipe without disturbing the joints between the flashing and the pipe or between the flashing and the roof. This is accomplished, in general, by providing two similar telescoping flashing sleeves, one of which is secured to the pipe and the other to the roof, the two sleeves being capable of limited relative movements in various directions. Due to the long overlap between these two sleeves, no water can flow between these sleeves although they may be drawn somewhat apart atone point or another to permit the relative movements to take place.

Another object is to provide means which prevents complete disconnection of the main and counter flashings without interfering with the-limited relativemovements between these two members.

Another object is to provide an improved adjustable collar at the upper end'of the flashing, adapted to engage pipes of various diameters. This adjustable collar also permits the flashing to be passed over enlargements or projections on the pipe.

Other objects and advantages of this invention will be apparent from the following detailed description of one approved form of the device.

In the accompanying drawings:

Fig. 1 is a perspective view of the improved roof flashing in use.

Fig. 2 is a central vertical section through the assembly as shown in Fig. 1.

The pipe.

Serial No. 146,411.

Fig. 3 is a central vertical section, taken at right angles to Fig. 2 and substantially on the line 33 of Fig. 2.

Fig. 4 is a plan view of the flashing, the pipe-being shown in transverse section substantially on the line 4-4 of Fig. 2.

Fig. 5 is a horizontal section taken substantially on the line 55 of Fig. 2.

In Figs. 1, 2 and 3 is shown a portion of a. roof 1, having a covering, such as shingles 2, for excluding water. As indicated, a portion of the shingle covering 2 has been removedvto disclose the base plate 3 of the roof flashing, which base plate will ordinarily be anchored between the roof 1 and the shingles 2. Obviously, any other type of roof covering might be used instead of the shingles. The base 3 is preferably formed of a rectangular sheet of metal, having a central opening from which projects the tapered flashing sleeve 4 which surrounds the pipe 5. The pipe 5 projects substantially vertically through an opening 6 in the roof 1, and it is the purpose of this roof flashing to prevent the entrance of water or similar substances through the opening 6 in the roof. The flashing sleeve 4 is preferably of a frustro-conical form, having a substantially elliptical cross-section, and projecting at an angle to the perpendicular from the base plate 3, so that the center line of the conical sleeve will substantially coincide with the vertical center line of the pipe 5, while at the same time the base plate 3 will lie inan inclined plane corresponding to the inclination of the roof 1. Preferably this main flashing sleeve 4 is made of a separate piece of sheet metal, the lager end of the sleeve being secured about the edges of a correspondingly shaped opening in the base plate 3, preferably by crimping the edges of the two metal parts together and soldering same. The upper end of the sleeve 4 is largeenough to extend loosely about the pipe 5, as shown in the drawings.

A similarly shaped sleeve, or counterflashing 7 is adapted to fit snugly over the ma-inflashing sleeve 4, so that when the two sleeves are completely telescoped, the lower edge of sleeve 7 will extend closely adjacent the base plate 3., The upper edge of the sleeve 7 is flanged outwardly as indicated 9, provided at its lower edge with an inturned flange 10 adapted to engage tightly beneath the flange 8 on the sleeve 7 The two ends 11 of the split ring 9 extend out substantially radially and are apertured at 12 to receive a bolt 13, on one end of which is a nut 141- whereby the ends of the split ring may be drawn adjustably together. Preferably the upper edge of ring 9 is curled or crimped outwardly as indicated at 15 and embedded in a soft metal collar 16, preferably of wedge-shaped cross section as shown and adapted to engage snugly about the pipe 5. This collar 16 is formed of soft malleable metal, such as lead, and its thinner upper edge 17 is adapted to be calked tightly against the pipe 5 and soldered thereto, or secured in any other suitable manner. The soft metal ring 16 is split, like the other member 9 of the split collar, and the ends 18 of this soft metal ring extend beyond the ends 11 of ring 9 and are beveled and overlapped, as best shown in Fig. 4. Obviously, by tightening or loosening the bolt and nut 13 and 141-, the diameter of the split collar can be varied so as to accommodate different sizes of pipe 5, and by entirely separating the splitends of the collar it may be passed over projections of considerable size on the pipe. The split collar may be an entirely separate unit from the counter flashing sleeve 7, the two parts being held together by the engagement of flange 8 at the upper end of the sleeve in the channel formed between the main portion of the ring 9 andthe inturned flange 10 at its lower edge. Preferably, however, a tab 19 extending from ring 9 at the side diametrically opposite the split portion of the collar, is riveted or otherwise secured to the sleeve 7 so as to prevent the entire removal of the split collar from the sleeve. This tab 19 serves to keep the parts together when in storage or shipment, and prevent loss or theft of a portion of the flashing.

It will be obvious that the outer sleeve 7 may be lifted from its position of close engagement about the inner sleeve 4, so as to permit longitudinal separation of the pipeengaging collar and the base plate 3, and this movement will create a clear space between the two sleeves which will permit lateral. movement of sleeve 7 in any direction with relation to sleeve 1, or will also permit tiis outer sleeve to be tilted in any direction to a limited extent with relation to the inner site sides of the inner flashing sleeve 4. Projections 21 extend inwardly from the outer sleeve 7 into the depressions 20. These projections 21 may be formed by pressing inwardly portions of the outer sleeve, or as here shown, rivets .or similar projecting members may be secured to the outer sleeve.

If the rivets are used the head of the rivet is soldered over to prevent leakage at this point. The depressions 20, atleast at their upper portions 22, are sufliciently large to permit the projections 21 to move laterally therein to the extent permitted by the overlapping walls of the two sleeves. This interengaging means between the two flashing sleeves will permit all necessary movements of adjustment between the two sleeves but will prevent their disconnection when once assembled, so that no portion of the flashing can be lost or stolen. Obviously, the positions of the projection 21 and depression 20 might be reversed on thetwo sleeves, so that both would project outwardly instead of inwardly, or instead of a depression an opening might be cut in one sleeve to accommodate a projection from the other sleeve.

Preferably, however, no openingswill be formed through either sleeve, so that pro tection against water will be provided throughout the entire overlap of the two sleeves.

When the device is positioned for service,

and the collar 16 is calked or otherwise per manently secured to the pipe 5. If now, the roof 1 should settle with respect to the pipe 5, carrying down with it the base plate 3 of the flashing, this will not break loose the joint between the collar 16 and the pipe 5., but the sleeves 4 and 7 will simply separate to the extent necessary to permit this relative separation of the base plate and the clamping collar. Any relative tilting movements, or lateral movements, between the roof 1 and pipe 5 will be accommodatedin a similar manner. While each flashing is designed for use on a roof of a given inclination to the vertical, this flashing is adapted for use on roofs which vary considerably from this standard inclination, since the angle of the pipe 5 within the split collar 16 may be varied considerably, and also by separating the sleeves 4 and 7 they may be relatively tilted to accommodate' a consider 3 with relation to the center line of the pipe 5. It will be evident that the long overlap.

provided between the main flashing and the counter-flashing insures complete protection against the entrance of liquids? at thispoint,

even though considerable settling or displacement has taken place'between the roof and pipe;

I claim:

1. A roof flashing consisting of three'relatively movable parts: a base member having a projecting tapering sleeve, asimilarly tapered counter-flashing into which the first sleeve telescopes, and a split collar movably attached to the smaller free end of the counter-flashing and adapted to engage aboutv a pipe, and means for connecting the three members to prevent complete separation without interfering with limited relative movements therebetween.

2. A roof flashing comprising a sleeve adapted to loosely surround a pipe and terminating at one end in a split collar, the split collar comprising a metal ring having outwardly projecting portions adjacent the split therein, means for adjustably connecting these projecting portions, and an inwardly projecting soft metal ring secured to the free edge of the first ring and adapted to engage about the pipe, the ends of the soft metal ring being beveled and overlap ping.

3. A roof flashing comprising atapered sleeve the smaller end of which is adapted to loosely surround a pipe, and is formed with an outturned flange, and a split collar adapted to engage about this flange, the collar comprising means for adjustably drawing the split ends together, and a soft metal ring on the collar adapted to snugly engage the pipe.

4. A roof flashing comprising a tapered sleeve the smaller end of which is adapted to loosely surround a pipe, and is formed with an outturned flange, and a split collar adapted to engage about this flange, the collar comprising means for adjustably draw,-

ing the split ends together, and a soft metalring adapted to engage snugly the pipe, the adjacent ends of the split soft metal ring being beveled and overlapping. 5. A roof flashing comprising a tapered sleeve the smaller end of which is adapted to loosely surround a pipe, and is formed with an outturned flange, and a split collar com prising a sheet-metal ring having an inturned flange to engage about the first mentioned flange, means for adjustably connecting the ends of the split ring, and a soft metal ring formed about the free edge of the first ring and adapted to snugly engage the pipe, the adjacent ends of the soft metal ring extending beyond the ends of the sheet metal ring and being beveled and overlapping one another.

6. A roof flashing comprising a flat metal plate having a sleeve extending from one face thereof, the sleeve tapering inwardly as it recedes from the plate, a second similarly shaped sleeve overlapping the first sleeve, the sleeves being so proportioned that they may be almost completely telescoped one within the other to normally form a double-walled flashing, a soft metal collar at the free end of the second sleeve for snugly engaging a pipe, the sleevesbeing free to separate to a limited extent to accommodate themselves to relate movements of the pipe and the roof to which the flat metal plate is attached, and I interengaging means between the two sleeves to prevent their complete separation.
