WATER-CLOSET CONNECTION.

Specification of Letters Patent.

Patented Aug. 24, 1915.

Application filed May 24, 1912. Serial No. 699,579.

17 '0 all whom it may concern Be it known that I, J OSEPI-I J. CoseRovn, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Water-Closet Connections, of which the following is a specification, reference being had therein to .the accompanying drawing.

This invention has relation to water closet connections and has for its object the provisions of novel means for connecting a water-closet or similar article with a soil pipe so as to avoid breaking the soil pipe, the floor flange of the closet, or the floor flange of the connection, or any other damage to the closet or its connections: by the.

settlement of the soil pipe or the sinking or sagging of the floor. I

My present invention consists in a novel connection for water-closets comprising a combined floor plate and flange for the soil pipe having a seat to receive the collar surrounding the closet outlet, said floor plate and flange being in the form of a crimped or corrugated ferrule of thin metal which is soldered at its lower inturned edge to the soil pipe and has its upper edge or seat part reinforced and strengthened by a non-flexible metallic ring, whereby I secure a perfectly rigid and strong seat part and can use a thin metal for the body of the ferrule to give flexibility where the same is required.

My invention further consists in the provision of novel means for attaching the combined floor plate and flange to the closet bowl and for attaching the closet bowl to the floor.

In the accompanying drawings illustrating my invention applied to an earthenware closet and a metallic soil pipe: Figure 1 is a vertical, sectional view of a portion of a water-closet and a portion of a soil pipe with my improvements, applied thereto. Fig. 2 is a horizontal sectional view on the line ww of Fig. 1, looking downward.

The water-closet designated 1, is of any desired type and formed with the outlet passage 2, terminating in a flange or projection 3, which is threaded, combed or slotted on the outside as shown at 4, to receive a collar 5, which latter is slightly tapered inwardly toward its lower end, so as to rest in a correspondingly tapered seat formed in a ferrule 7. The ferruley7, is a separate 1 structure from the soil pipe 8, which latter is of the usual form, being a section of lead tubing of interior diameter corresponding to the interior diameter of the outlet passage of the closet. The ferrule 7 is formed with a horizontally extending portion 9 that constitutes the floor flange of the soil pipe and the inner edge of the portion 9 is soldered to the soil pipe so as to form a water and gas tight joint therewith. The central portion of the ferrule is crimped or corrugated as shown at 10 to give the desired amount of flexibility and the upper portion of the ferrule is so shaped as to form a tapered seat at 11 for the reception of the tapered collar 5, carried by the flange or projection 3 of the water-closet. A rigid ring of metal 12, surrounds the upper or seat portion 11, of the ferrule and this ring, which may be of galvanized steel or iron or of other suitable material, is formed with a horizontal flange 13, at its upper edge and the metal of the ferrule extends over the top and around and below the bottom of the flange 13, so as to retain the ring in position.

The ferrule is attached to the bowl by clamps 14, which are formed of stamped or pressed metal, preferably galvanized steel, and having upturned outer ends 15, that bear against the bottom of the'closet base 16, the inner ends of the clamps bearing against the bottom of the flange at the upper end of the ferrule, formed by the flange 13, of the ring 12, and the overlapping metal of the ferrule. The clamps 14 are formed with slots 17, through which are passed hollowbolts 18 that pass through holes 19 in the closet base 16, and are secured therein by nuts 20. Solid bolts 21 extend through the hollow bolts 18 and screw into the floor 22, and cap-nuts 23, screw onto the upper ends of the bolts 21, and serve to cover and conceal the upper ends of the hollow bolts 18, and the nuts 20 thereon, and at the same time fasten the closet base to the floor.

In assembling the parts, the ferrule is first soldered to the soil pipe. The solid bolts 21 are then screwed in place, the hollow bolts with the clamps 14 attached, then slipped into position and kept temporarily in place with paper or other soft material packed underneath them. The closet is then set in place, the nuts 20 screwed onto the hollow bolts, thereby making-up the closet floor flange. The cap nuts 28 are next screwed to the solid bolts 21, thereby securing the closet to the floor.

The rigid ring of metal 12, which surrounds the seat portion of the ferrule, renders that portion firm, strong and rigid without, in any way, detracting from or interfering with the flexibility of the ferrule and by the construction described and shown I get strength where strength is needed and can use a thinner sheet metal for the ferrule than where the rigid ring is not provided, thereby securing flexibility where flexibility is needed. v

As will be seen, none of the weight of the closet is supported by the soil pipe, nor is any part of the closet connections brought into such contact with or relation to the soil pipe as to affect or to be aflected by any change in the position of the soil pipe with reference to its alinement with the closet outlet opening. Any unevenness in the floor or abnormal condition or relation of the soil pipe to the closet is compensated for by the flexible corrugated ferrule, which yields under slight strain without breaking or rupturing the parts connected thereto or opening up any scams or subjecting the parts forming the closet connections to the soil pipe, to strain or other injurious effects.

The application of the corrugated flexible ferrule embodies the novel desideratum of a metal-to-metal flexible connection, between the closet and soil pipe, which will enable the closet, soil pipe and joint elements to be installed and maintained in satisfactory relation and insures a water tight joint under the varying conditions which are encountered in the first installation of the closet and after lapse of time.

I claim:

1. A ferrule for connecting the outlet projection or flange of a water-closet to a soil pipe, consisting of a floor flange portion adapted to be attached to the soil pipe, a rigid upper seat portion adapted to embrace and form a sleeve joint with the outlet projection or flange of the closet and an intermediate flexible portion.

2. A ferrule for connecting the outlet pro jection or flange of a water-closet to a soil pipe, consisting of a floor flange portion adapted to be attached to the soil pipe, an upper seat portion adapted to embrace the outlet projection or flange of the closet and form a sleeve joint connection therewith, a rigid ring surrounding the seat portion and an intermediate flexible portion.

3. The combination with a water-closet having an outlet flange and a soil pipe, of a ferrule having a floor flange portion soldered to the soil pipe, an upper seat portion receiving the outlet flange of the closet and forming a sleeve joint connection therewith, a rigid ring surrounding the seat portion and an intermediate flexible portion.

4. The combination with a water-closet bowl having a base, a soil pipe, and a ferrule connecting the closet and soil pipe, and having an external flange at its upper end, of clamps extending under the flange of the ferrule and bearing against the bottom of the closet bowl base, hollow bolts passing through the said clamps and said base and solid bolts passing through said hollow bolts and attached to the floor under the said base.

In testimony whereof I aifix my signature in presence of two witnesses.

JOSEPH J. COSGROVE.
