ROOF FLASHING.

Application filed March 19, 1928. Serial No. 262,742.

This invention relates to roof flashings,

, one of which is adapted to maintain a watertight joint between a roof and a pipe, such as a, ventilating pipe, projecting substantially vertically therethrough.

These flashings commonly comprise a flat base plate which is anchored in or upon the roof materialsand a sleeve portion which may consist of a plurality of inter-engaged members, the sleeve portionprojecting upwardly from the base and usually having a generally conicalforin, the smaller upper end of the sleeve being tightly secured about the pipe, usually by means of a soft metal 5 collar which is calked to the pipe The pipe, which extends downwardly through the flashing and an opening in the roof, is usually supported from below independently of the roof, and if the roof should settle an appreciable amount, or change its angular relation to the pipe, the joint between the collar and the pipe will be broken away unless the sleeve is provided with some form of telescopic or slidingconnection to allow for these'relative movements between the roof and pipe. A flashing provided with such a telescopic connection is disclosed in the patent to Robert J. Stephenson, 1,587,250,

granted June 1, 1926, the present invention relating to certain improvements in the type of roof flashing covered by that patent.

The principal object of the present invention is to provide a roof flashing of this general type adapted for use with roots of various inclinations. In general terms, the

sleeve member consists of a plurality of annular sections, theupper end of the uppermost, section being anchored in the soft metal collar which engages the pipe, and the lower end of the lowermost. section being secured about the periphery of the opening of the base plate. A telescopic connection is provided between two of the sleeve sections .to

accommodate the relative vertical movements between the roof andpipe. A rotary connection between another pair of the sections is positioned in a plane at an angle to the central axis of the sleeve members, so that the inclinationof the axis of the clamping collar and telescopic connections with relation to the roof or base plate can be varied. A third connection between a pair of the sleeve sections permits 7 a limited tilting movement between these sections to accommodate a small change in the angular relation between the roof and pipe, or to orig- .inally adapt the flashing for use withroofs of varying inclinations. The general object is to provide separate connections for accommodating the flashing to use with different roof angles,- without necessitating any tilting movement betwen the members of the telescopic joint, the axis of this joint being maintained substantially coincident with the central axis of the pipe so that there will be no binding between the members of the telescopic connection.

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 's a plan view of the flashing as applied to a horizontal roof and a vertical p1 e.

ig. 2 is a central vertical section taken substantially on the line 2-2 of Fig. 1.

Fig. 3 is a side elevation of the flashing as applied to a vertical pipe and a roof extending at substantially 45 to the vertical or horizontal.

Fig. 4 is a partial central vertical section, corresponding to the upper portion of Fig. 2, but showing the use of the upper tilting connection. I V v The base 1 of the flashing is in the form of a rectangular sheet metal plate, which is anchored to the roof in any suitable manner usually being secured between the roof and the shingles or other roof covering. The plate 1 is formed with'an elliptical opening 2, large enough to permit the pipe 3 to pass through at various angles. A soft metal collar 4 is adapted to be clamped securely about the pipe 3. This collar will initially have an inner diameter (particularly at its lower end) somewhat larger than the diameter of the pipe 3, but the collar is formed of lead or other suitable soft metal, and a clamping means is provided for contracting the upper portion of the collar and forcing same into snug engagement with the pipe. In the form here shown, a split wire ti 5 surrounds the upper portion of the collar '4, the eyes6 at the ends of the split ring 5 being adjustably connected by a screw bolt 7. By tightening this bolt the ring 5 may be contracted about the soft metal collar 4e, thus forcing the collar into engagement with the pipe, after which the upper end of the collar may be calked tightly to the pipe.

A sleeve membe of generally conical form connects the collar 4 with the base plate 1 so as to prevent water from passing ClOY 1'l1 wardly about the'pipe 3tlirough the roof opening 2. This sleeve consists 0;" a pin rality of annular sections, formed and connected as hereinafter specified in detail.

The lower sleeve member 8 is in the form of the trustum of a cone the lower lar 'er end of the sleeve being secured about the edges'ot the opening 2 in base plate 1 in anysuitable manner, usually by crimping the edges of the sleeveand plate together as in; dicated at 9. The sleeve 8 might be stamped intergrally tromthe base plate '1, thus entirely eliminating the oint mentioned. The upper open end of sleeve 8 terminates in an outwardly extending annular flange 10,

which lies'in a plane having an angle of substantially 22 5 with: the plane of the base plate 1. A second, substantially cylindrical sleeve member 11 has its upper open end provided with an outwardly extending annular flange 12 lying in a plane perpendicular to the axis of the cylinder. The lower end of the sleeve member 11. terminates in a plane extending at an angle of 22 to the axis of the cylinder, this end of sleeve 11 being flared or crimped so as to extend outwardly and then inwardlyaround the flange 10 on the lower sleeve member 8, The lower end 13 of cylindrical sleeve 11 is not crimped tightly to the flange 10, but the flange 10 is capable of sliding in the recess formed at the lower end of member 11 so that the lower end of member 11 may be rotated about the upper end of inei'nber 8. With the parts in the position shown in Fig. 2, the angle at the lower end of sleeve member 11 counteracts the angle at the upper end of sleeve member'S so that the vertical axis of cylinder 11 is substantially perpendicular to the plane o'f base plate 1.1 It the sleeve member ll is rotated through 180 with relation to is of suilicient inner diameterto fit loosely' aboutthe outer periphery of flangelil at t upper "end of sleeve 11, and the inwardly extending flange 15 on sleeve member 1 1: has

7 an inner diameter slightly larger than the;

outer diameter of sleeve 11 whereby the an cess 21 tor receiving the outwarch nular flanges 12 and 15will overlap to pre- Sleeve member 17 is secured at its upper end to assert metal collar l, preferably by having this end of the sleeve member imbedded-within the softmetal of the collar. The lower end of sleeve member 17 extends outwardly at 18,.downwardly at 19, and in wardly at 20, to form an inner annular rel 7 projectin flange 16 at the upper end of ....eeve member 14;. This lower portion of sleeve 17 fits rather snugly about the outer periphery of ii o 16. but the recessv oi considerably great height than the thickness of the flange. 16 so that the flange may be tilted therci 7 for example as indicated in Fig. 4, so as to displace the central axis of sleeve member 1'? and clamping collar l angularly with relation to the axis of cylindrical sleeve lit is oesirable that when this assembled flashing is installed between the pipe and root, the longitudinal axis of the cylindrical sleeve members 11 and 14L 'shall'be substantially coincident with or parallel to the axis of pipe 8 so that as the root settles with relationto the pipe the telescoped sleeve members mav ree v slide over one another without dai that ith the parts positioned.- as shown in Figs. 1 and 2 this desired relation of the telescoping members with respect to the axis of the pipe is obtained for substantially flat roots, that is when thereof is horizontal and the pipe vertical. l Vith the members adjust ed as shown inllig. 3, that isfwhen sleeve member 11 has been rotated 180 "from the position siown in Fig. 2, the same relation between the upper sleeve members and the pipe obtain as the Fig. 2 position but the ba seplate'1 is adapted for a 4:5" root :1. gle. t lting the upper sleeve member 1 ans clampmg collar l with relation to the upp cylindrical sleeve 14, 215 shown in'l ig. 4, the flashing maybe used onfroofs having angles intermediate or varying from the horizontal and 45 angles shown in Figs. 2 and 3! This tilting connection between the two upper sleeve members will also accommodiate tilt ing movements of the pipe with relation to the root, or vice rersa. after the devicehas been installed. In other words, if the root settles at an angle, as is orten the case, this relative tlltingmovement can be accommodated by the connection between sleeves 1 h and 1'? without causing binding between the telescoped sleeve members 11 and 1 1. A certain amount of angular adjustment is also possible between these telescoped members,

but. it is desirable to take up this angular ad'- 1 or" binding. It will be seen imam ' members, for reasons already specified.

It should also be'noted that the sleeve sections are all off materially greater inner diameter than the outer diameter of pipe 3, so that an appreciable angulartilting ot the pipe 3 in the soft metal collar 4.1nay be utilized when the flashingisinstalled to help adjust the device to thciangleof any par- 7 ticular roof. All of'ithese teatures provide a considerablefrangc of fiClJllStfibllllv to this flashing so that the flashing may be used on' a roof of any angle normally encountered without relatively tilting the two telescoping sleeve members 11 and 14 or varying their angle with relation to the axis of the parts to an extent sufficient to cause binding in the telescopic connection.
