STACK CARRIER AND BOWL CONNECTION Filed Nov. 18, 1958 3 Sheets-Sheet a INVENTORS VINCENT T MANAS Y GEORGE I. FLEGEL ATTORNEYS Unite States Patent M STACK CR AND BOWL CONNECTION Vincent T. Manas, Washington, D.C., and George J.

Flegel, Michigan City, Ind., assignors to Josam Manufacturing Co., Michigan City, Ind., a corporation of Delaware Filed Nov. 18, 1958, Ser. No. 774,659 4 Claims. (Cl. 4252) Ths invention is directed to improvements in closet bowl fixture carriers and has for its general object the provision of a carrier and soil line fitting adaptable to vertical line stacks and to vertical connection leading into branch waste lines.

In tall buildings such as hotels, office buildings, etc., it frequently is desirable to connect single bowl fixtures to vertically extending soil line stacks and due to the height and weight of the soil line, supporting connections for the stack are installed at each floor of the building to distribute the load of the stack from floor to floor. Likewise supporting connections are desirable for vertical soil line connections of bowl fixtures on a single floor to a horizontal waste line branch. The general object of this invention is to provide an improved supporting connection.

A more specific object is to provide a stack fitting and associated fixture carrier of simple and economical structure and wherein the fixture outlet may be connected directly to a stack fitting by an adjustable ferrule in the minimum amount of space thereby requiring only a minimum space for the installation.

A further object is the provision of a carrier and fitting which can be utilized in building structures where limited utility space or chase space is available and wherein backto-back or single closet mountings may be required one above the other from floor to floor on a single stack.

A still further object of the invention is a carrier plate structure on a stack fitting the carrier plate being reversibly attachable to the fitting for the mounting of syphon jet type or blow out type of closet bowl fixtures.

Other objects of the invention will become apparent to those skilled in the art from the following description referring to the accompanying drawings. The essential characteristics are summarized in the claims.

In the drawings,

FIG. 1 is an elevational view partly in cross section showing a close installation of a blow out type of bowl fixture requiring only a minimum space;

FIG. 2 is a front elevation of a carrier plate adapted to be attached directly to a special fitting comprising part of the vertical stack line;

FIG. 3 is a plan view of a carrier locking and packing gland ring;

FIG. 4 is a side view of a ferrule constituting the soil line connection between the bowl fixture and the special stack fitting;

FIG. 5 is a perspective view of one of two adjustable connections between the bottom region of the carrier plate and a carrier foot or pedestal secured to a roughed in floor;

FIG. 6 is an end view of the carrier plate partly in section along the line 6-6 of FIG. 2; and

FIG. 7 is a sectional view taken along the line 77 of FIG. 2.

The present invention contemplates a closet bowl installation wherein a single bowl or two so-called back-toback bowls is or are suspended upon a carrier or carriers which support the fixtures at the correct elevation above the finished floor independently of the wall to which the fixture is juxtaposed. The fixture support or carrier is shown as being connected directly to a special fitting comprising part of a vertical stack for the purpose of 3,054,l l9 Patented Sept. 18, 1962 illustrating one form of installation. The carrier is in the form of a vertically reversible flat plate structure having a hub formation which extends into an opening of the wall after the stack and carrier are installed, the opening being provided at the time the wall is built.

Referring to the drawings, a vertical soil pipe line or stack 10 is shown, for purposes of illustration, with a special fitting generally designated by the numeral 12 with opposed branches 14 and only one fixture installation illustrated. Attached to the branch 14 is a carrier plate 1'5 supported by adjustable pedestals or feet 16 at each lower corner of the carrier plate. Bolts 17 serve to secure the pedestals to the plate after the carrier plate is installed on the fitting. Floor bolts 18 secure the pedestals to the roughed in floor 20. These pedestals or feet may be attached to the front of the carrier. plate or to the back of the carrier plate as shown in full lines in FIGS. -1 and 5.

Thus the pedestals support the carrier and the carrier supports the stack at each floor of a building when the fixtures are installed one above the other i.e., floor to floor in the installation illustrated, on a single vertical stack.

The fittings 12 are installed in the stack at each floor with the branches 14 disposed at the proper elevation relative to the finished floor surface 21.

The carrier plate 15 is reversible for either a blow out or a syphon jet fixture installation and FIG. 1 illustrates a blow out type of installation wherein the bowl fixture is supported on three bolts, two upper bolts 26 located equi-distantly from the center line of the horn 28 of the bowl fixture and a lower centrally located bolt 27 which is supported by a slide block 29 adapted to be clamped or secured to the carrier in the slideway formation 30 of the carrier plate 15. The bolts are secured to the carrier plate to support the bowl fixture independently of the wall structure.

The soil line connection between the outlet or fixture horn 28 consists of a single adjustable ferrule member 32 having a cupped outer end 33 and having an external straight thread 34 adjustably engaging an internal straight thread 35 formed in the carrier supporting part 14a of the branch structure 14 of the fitting 12. The cup part 33 of the ferrule 32 is so disposed by adjustment of the ferrule relative to the fitting branch as to compress the usual horn gasket 40' when the fixture is bolted in place after the wall is built.

To fix the carrier upon the fitting branch, the branch is provided with an annular slightly tapered seat 42 (note the left branch in FIG. 1) terminating at a beveled shoulder 43 having two key lugs 44 formed thereon ver tically spaced apart so that the carrier plate may be reversed vertically.

The carrier plate is provided with a hub structure 45 projecting forwardly with a slightly tapered opening 46 and terminating on the inner side of the plate in a beveled annular surface 47 complementary to the beveled shoulder surface 43 of the fitting branch. Keyways 48 formed in the beveled surface 47 fit the key formations 44 of the fitting when the carrier hub is applied to the fitting branch. (See FIG. 2.)

To center the carrier hub on the fitting branch after 'it is applied to the branch a clamping collar or ring 50 is threadedly mounted on the ferrule forwardly of the branch end and equi-angularly spaced clamping screws 51 are located on the ring 50 to press upon the forward end of the carrier hub, the 'hub being of sufficient diam- .eter to afford a compression surface against which the connection from fitting to bowl fixture.

when the ring 50 is screwed toward the fitting branch to seal the fitting-ferrule connections. Thereafter the clamping bolts 51 are cinched home against the hub of the carrier and the carrier becomes vertically aligned. Thereafter the carrier feet may be adjusted to bear upon the roughed in floor structure 20 and become buried in the finished floor 21. Should a test show a leak at the ferrule packing the clamping screws 51 may be loosened and the ring 50 is then turned to further compress the packing. This can be done even after the Wall is constructed. Likewise if the ferrule is adjusted improperly relative to the bowl form 28, the ferrule may be adjusted in the same manner.

It will be understood by those skilled in the art that the carrier plate will not be cinched home upon the branch seat by the screws 51 until an inspection test tight fit is obtained at the packing gland 52 whereupon the clamping screws 51 are tightened against the end of the carrier hub.

For a siphon jet installation with the carrier plate infverted from the FIG. 1 position, the two lower closet mounting studs, used therein in place of the single lower stud 27 for the blow-out type, serve the function of the nut and bolt 17 for securing respective feet to the carrier plate. Here again, the vertical leg of the right-angle bracket-shaped pedestal may be placed at the back or front of the carrier plate 15 with the fore and aft projecting portions of the side flange 16a respectively embracing the vertical side edge of the plate for stability in either case, as in the FIG. 1 type installation.

With additional diametric pairs of keyways or notches angularly spaced at 45 from the vertical pair, as appear at 48a in FIG. 2, the fitting may be installed at a corresponding angular displacement, about the intended axis of the ferrule 32, from the position of FIG. 1. For greater flexibility, permitting a proper installation of the carrier, hence bowl fixture, when the stack or other line is a few degrees out of plumb in lateral sense, a plurality, say three, of like arcuate slots may be provided in the carrier plate just outside of and concentric with the tapered opening '46 thereof; and the fitting is provided with a radial formation, as a circumferential flange or shoulder, inward beyond the bevel 43, which has circularly spaced tapped blind holes for reception of bolts passed through the respective slots to secure the carrier and fitting together in proper relative position.

The advantages of the overall structure appearing in the drawings, such as compact fixture mounting and waste line support, may be desired in installations not using a special fitting such as 12, but rather one of various prior art waste line fittings having a male or female standard pipe threaded lateral opening for a coupling assembly In such cases, the carrier supporting and engaging formations of the branch 14a, that is, the portion 42, bevel 43 and keys 44,

may be provided on one end of a special coupling, having at its other end threads complementary to those of the opening of the waste line fitting, and an intervening Wrench-engageable formation whereby the coupling may be screwed securely into the fitting to convert the same into a special fitting of the character of fitting 12. By such a coupling, the above characterized prior art fittings may be supported by the carrier plate and pedestal and 5 connected to the bowl fixture in the manner of FIG. 1.
