To all whom it may concern: I
Be it known that I, ROBERT FRANKLIN F1rE,a citizen of the United States, residing at Canton, in the county of; Stark and State of Ohio, have invented a new and useful Stack-Flashing, of which the following is a specification.
This invention relates to stack flashings and is designed to provide aflashing that is quickly and easily applied to a variety. of sizes of pipe.
Another object is to provide'aflashing that will readily fit roofs of various pitches with the same facility.
With these objects in View the invention consists in the novel construction and arrangement of parts, hereinafter descr bed, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, 't being understood that various changes in'the form, proportlons, size and minor details of construction may be made within the scope of the appended claims, without departing from the spirit or sacrificing any of the advantages of the invention.
In the drawings:
Figure 1 is a sectional view of my im-.
Fig. 2 is a similar view on a somewhat reduced scale showing my flashlng applled to a pipe of comparatively small diameter. Fig. 3 is a view similar to Fig. 2 show ng pipe of slightly larger diameter than F1g. 2. Fig. 4: is a cross sectlonal view with the calking sleeve trimmed down and a slightly larger pipe than Fig. 3 shown fitted therein. Fig. 5 is a similar view wlth a still larger pipe shown in conjunctlon with the flashing. Fig. 6 is a similar View with the flashing shown in the position it would assume on a roof of greater pitch than Figs. 2, 3, 4 and 5. Fig. 7 is a view of a slightly mod fied form in which I use a plurality of grooves or indentations on the calking sleeve, each at which to trim the calking sleeve for ferent sizes of'pipe.
Similar numerals of reference indicate corresponding parts throughout the several figures of the drawings. a To'those' familiar with the; installation and adjustment of flashingsof this charac ter now known and used, it is well known that only a very light variation in thesi'zes of pipes that can be used with a certainsize dif- roove or indentation indicating the point,

flashing, is possible. -For this reason the craftsman who is to install the flashing must determine the size pipe that will be neces sary for a certain job and then order his flashing to fit the pipe. This necessitates either a loss of time in getting a particular size flashing for each size of pipe or the carrylng n stock by the craftsman of a large:
variety of flashings for different sizesof pipe; In order to overcome this difficulty I have designed a flashing, the calking sleeve of which has-a wide range of adjustment and can fit'a large'variety'of sizesof pipe and is also adapted to be as readily adjusted to a roof of the maximum pitch as to a flat roof. As shown in the drawings my flashing comprises a sheet metal frusto-conical' POP-I tion 1 which has the laterally extending. flange or base 2 by means of which'it is secured to the roof. .The upper end of this frusto-couical collar is turned outwardly to form a flange 3 about which the lower end of the calking sleeve formed oflead or. similar soft malleable metal is molded. I form this calking sleeve indicated at 4 of approximately twice the length of calking sleeves on flashings now known and-employed and about mid-way between the upper end of the said calking sleeve and the point where it isjmolded about the flange 3, 11 form a groove or indentation 5for' a purpose to be hereinafter set forth.
[Referring now more particularly to Fig. 2 I have shown my i'mproved flashing ap plied to a-pipe of relatively small diameter such for instance as an inch and a half waste pipe and as shown in this figure, by virtue of the extreme length of the calking sleeve the craftsman is enabled to hammer it into close contact about the pipe to form a water tight and air tight joint. It is readily seen that this will not be possible with a calking sleeve ofthe ordinary construction and of similar diameter, since the calking sleeve would neither reach to the pipe nor would it be practical. even though the sleeve would just reach the pipe to hammer it suflicientlyin order to do so. "Fig. 3- shows the same sizeof flashing applied to a pipe of a slightly larger diameter than that shown in Fig. 2 and as will be readily seen in thisfigure,no change has been madein the flashing. Since the pipe is of a slightly larger diameter a. trifle less hammering is necessary to bring the calking sleeve into close contact about the pipe.
the now remaining upper end of the calls in-g sleeve and as shown in Fig. i, the remaining port1on 1s hammered into contact with the pipe. Should a still larger size of pipe be required it is readily seen that it can be as easily used by simply hammering the calking sleeve to fit. As shown in Fig. 6 :a great variation is possible in vthe pitch of the roofs on which this flashing can be used. V p
.Refer-rin-gnow to Fi '7 of the drawings 1 have shown a calking sleeve with grooves 6, 7 and 8, all similar to the groove 5 and in full lines in this figure I have shown a pipe of the proper diameter to fit within the extreme upper end of the said calking s leev-e when a pipe of the next size larger than the one shown "full lines is to be used, the upper end of the calking sleeve is severed at the groove 16 and will then take sizes of the pipeup to and including the one shown in dot and dash lines It is thus seen that sizes of pipe up to the size indicated by lines for-med with a dash and two dots can be used, this being. the :size that would require the trimming of the calking sleevedown to the last groove. 7 i 7 From the foregoing it will be obvious that my flashing need only bemade in a very few different sizes, each size having a variation suflicient to cover a half dozen or more different sizes of pipe and since the spacing of the grooves from the upper end of the calking sleeve are designed to enable the plumber vto determine exactly where to trim the calking sleeve in order to ieave enough metal to insure cailzing the pipe properly without danger of the lead cracking away from the lower portion or the -flashing, a considerable amount of time can be saved in applying the said flashing;
Having fully described my invention what I claim as new and desire to secure by Letters Patent, is I 1. A stack flashing comprising a frustoconical collar having means for attachment to a roof and adapted to inelose a pipe, a irusto-conical cal-king sleeve of soft malleable mate-rial entirely surrounding and supported upon the upper end of the collar, said calking sleeve being of suliicient length to allow t he'u pper end thereof to be forced in to accommodate several different sizes of pipe. V
2. A stack flashing comprising a frustoconical collar having means for attachment to a roof and adapted to inclose a pipe, an outwardly disposed annular flange provided around the upper end of said irusto-conical collar, a frusto-conical calking sleeve of soft malleable material entirely surround ing and supported upon said annular flange, said sleeve being conical on its interior and adapted to fit the pipe and be forced down thereon, said pipe being spaced from the collar and from the major portion of the sleeve sufficiently to permit the collar to be set at different angles to the pipe, the sleeve being adapted to have its upper endforced into closer contact with the pipe, said sleeve being of sufficient length to allow the upper end th-ereoii to be forced in to accommodate several different sizes of pipe.
3. A "tack .tiaslrng comprising a trusteconical collar vhaving means for attachment to a roof and adapted to inclosea pipe, a fmsto-conical callring sleeve of soft. mall'eablemateriai having va, groove or indentation therein, the said groove or indentation being spaced at a predetermined point below theupper extremity of the saidirustoconical calkin-g sleeve, the, said calk-ing sleeve being of suliicient length to allow the upper end thereof to be forced in to accommodate several difl'erent sizes of pipe, the upper portion of said caiking sleeve being adaptedto .be severed from the lower portion at-the point indicated by thesaid groove or indentation to enable the said calking sleeve to accommodate aastill larger size of] ing adapted to be, severed from the lower portion at the point indicated by the said groove or indentation to enable the :said calking sleeve to accommodate a still larger size of pipe than any hereinbe'fore referred to, and the portion of the ealizing sleeve re-. maining after said upper portion has been severed at the point indicated by said groove or indentation being of suihcient length to allow the upper end thereof tobe forced in to accommodate several different sizes of pipe.
