ROOF-COLLAR.

SPEGIFICATION forming part of Letters Patent No. 549,352, dated November 5, 1895.

Application filed June 27, 1895.

To all whom it may concern:

Be it known that I, HENRY C. FOLGER, of Somerville,- in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Roof- Collars, of which the following is a specifieation. r

This invention has for its object to provide improved means for forming a tight joint I o around a pipe, such as a ventilating or soil pipe or a steam-pipe, where it passes through the roof of a building.

The invention consists in the` several improvements, wh ich will be first described, and

then pointed out in the elaims.

Of the accompanying drawings, forming a part of this specification, Figure 1 represents a perspective view of a collar and its flashing eonstructed in aceordance with my in- :o vention. Fig. 2 represents a perspective view of the elastic binder which is applied to the upper portion of the collar. Fig. 3 represents a longitudinal section of the collar before it is secured to the flashing. Fig.

2 5 4 represents a sectional view showing the entire device applied to a pipe and to the roof of the building. Fig. 5 represents a sectiou on the line 5 5 of Fig. 4. Fig. 6 represents a sectional view showing a collar of a some- 3o what different constructio. 1- i i The same letters of reference indieate the same parts in all the figures.

In the drawings, a represents a collar or tube, the lower end of which is forned to 3 5 correspond to the roof to which it is to be applied, said ring being beveled for a ptch roof, as here shown, the bevel or inelination of said lowerend being such that when the collar is in placev on the roof 'it will stand in 4o a substantially vertical position. For a flat roof the lower end of the collar would be at right angles with the length of the eollar.

The collar a is made of lead or any other suitable malleable metal or alloy. The lower end of the collar is forned in such nanner that it can be readily secured to a sheet of metal b, which is to rest upon the roof and be interposed between the roof and the shingles, said sheet being t-ermed for the sake of convenience a flashing The preferred construction of the collar, whereby it is Serial No. 554,262. (No model.)

adapted for attaehnent to the flashing, is that shown in Fig. 13, the collar being provided with an outwardly-projecting flange a' near its lower edge and being reduced in thickness below said fiange to form alip a2, ada-pted to be turned outwardly against the under side of the flashing b, the flange bearing on the upper side of said flashing h. The flashing b is provided with an opening fornod to receive the lower end of the collar and to fit snugly against the fiange af thereof. After the insertion of the lower end of the (-ollar into the opening in the flashing Z) the lip (2 is turned outwardly, as shown in Fig. Jr, and pressed firnly against the under side oi' the flashing b, the latter being thus g'asped or clamped between the lip and the iiange I prefer to additionally secure the lip o? to the fiashing b by a solder-joint.

The flashing Z is laid upon the -oof c, as indieated in Fig. 4, and supports the eollar a in a substantally vertical position.

The soil-pipe (l is passed through the collar and extends to any desired height above il. The upper end of the collar is contrneled to form a neck u, whichapproximately iits the exterior of the pipe (1, the collar below said neck being preferably enlarged and tapered outwardlyfroin the neck to the Hangi' d', this form enablug` the eollar to aeeonnodate itself to the ppe and to various angles of inclination of; the roof. In other words, the eollar may oceupy a somewhat inclined position while surrounding the vertical pipe and the degree of inclination of the collar may vary to a considerable extent, as may be necessitated by the piteh of the roof.

erepresents a binder or clamp, which is secured to the upper portion of the collar a and is constructed to be contracted upon the collar and to press the la-tter closely against the external surface of the pipe (I. The pressure thus created will be practically sufieient to form a Water-tight joint between the collar and the pipe; but asan additional safeguard I locate the binder below the upper end of the collar, so that the binder will servo as an anvil and upset the upper end of the collar by hammering down or upsctting the portion of the collar that projects above the binder, thus compressing the metal of the eollar be- IOO binder.

tween the binder and the pipe, this operation being equivalent to ealking the joint between the collar and the pipe. A portion of the displaced metal is disposed in the form of a l'p or flange a;i upon the upper edge of the To prevent the binder from slipping downwardly upon the collar during the upsetting or calking operation, I form the internal surface of said binder so that vit will penetrate the collar, and thus lock itself thereto againt downward movement. To this end an inwardly projecting rib e' may be formed upon the binder, as shown in Fig. 4, or the binder may be construeted in any other suitable way to produce'the desired result.

The binder e may be provided with any suitable means for contracting it around the collar. I have here shown the binder made in one piece, which may be made of any suitably elastic band metal and provided with ears e2 es, which are connected by a screwthreaded bolt 64, having a nur. 65, rwhich the binder may be contracted. One end of the binder is provided with a recess es, along the upper edge of which extends a lip e, which isa continuation of the inner bearing-surface of the binder. The other end of the binder is cut away at e7 and formed to enter the recess ea. It will be seen that the described construction enables the binder to have a continuous bearing upon the collar, so that the binder supports the upset portion of the collar equally at all points, there being no interruption in the continuity of the binder. The binder thus construeted is adapted by its elasticity to conform elosely to any slight irregularities on the pipe, and thus make a continuous tight joint around it.

The collar may be supplied independently in the condition shown in Fig. 3 as an article of manufacture, the flashing being applied subsequently by the plumber. I prefer, however, to supply the collar and flashing permanently connected as an article of mat ifacture. i

It will be seen that the improved device, comprising the malleable collar, the fiashing, and the binder, enables a tight joint to be formed around a pipe at the point where it emerges from the roof of a building with comparatively little labor and without the employment of molten metal, the operator having only to secure the flashing to the roof in the proper position and then apply the binder and upset the projecting end of the collar, the latter operation being conveniently eected by an ordinary hammer.

The binder may be construeted in any suitable way to be contracted on the collar and thus bind it to the pipe, and said binder may be composed of wire having its ends twisted together. I do not limit myself, however, to the employment of a contractible binder, and may substitute therefor a continuous ring or band.

I claim-- '1. A roof-collar eomprising a malleable tube formed to eneircle a pipe, a contractible elastic binder having a continuous bearing edge formed to encirele the tube, means for contracting the binder, whereby it may be clamped upon the tube to serve as an anvil on which the upper end of the tube is upset, and a sheet metal flashing secured to the lower end of the tube.

2. A roof-collar comprising a malleable tube, a sheet-metal fiashing secured to the lower end of the tube, and an elastie binder embracing the upper portion of the tube, said binder having an internal rib to engage the tube and prevent downward movenent thereon, the malleable tube being adapted and arranged to be headed down over said binder.

3. A roof-collar comprising a malleable tube having an outwardly projecting inclined flange near its lower end, the portion of the tube below said flange being formed as a lip adapted to be turned outwardly and confine a sheet-metal flashing against said flange.

4. A roof-collar conprising a malleable tube having an outwardly projecting flange at its lower portion, a thin lip below said flange, and a contracted neck at its upper portion formed to bear upon a pipe passing through said tube.

In testimony whereof I have signed my name to this specifieation, in the presence of two subscribing witnesses, this 21st day of June, A. D. 1895.
