-6 Claims. (Gl- 4252) Thisinve-ntion relates to an improved carrier "for 'the bowl of wall hung water closets.

To obtain a better appreciation of the improvements contributed to the art by the present invention, the following should be borne in mind.

Heretofore, the design of wall hung closet carriers neces sitated a final adjustment of the carrier supporting structure-both behind and in front-of the finished wall. The final step inthe installation of the water-closet is of the utmost importance, as proper closet support eliminates the placing of any undue stress on the'soil pipe, or extension thereof, and the finished wall. "It'isobvious that the proper adjustment can be effected only with the exercise of painstaking care in the-limited space behindthe finished wall. The inability to rnake a proper adjustment in the confinedwall spaces as-demanded by the prior carrier designs has resulted-in unduestresses being imparted to both the wall and the plumbing'connection as well.

:It is therefore a main object of my invention 'to pre sent a carrier which is simple .in design and which can be mounted on the face of the finished wall requiring no .final adjustment behind the wall.

:It isa further object of my invention'to provide a carrier design which is composed of basic parts which are relatively simple to assemble and manufacture, thus assuring both ease of installation and alow unit 'cost.

These and other objects of my invention will become more readily apparent upon proceeding with 'the following detailed description read in the light of the accompanying drawings, in which Fig. 1 is a perspective exterior-view of :the closet carrier which is .the subject matter of my invention.

Fig. 2 is a perspective view of a soil pipe connected ,to the novel closet carrier.

Fig. 3 is a side elevation, :partly in section, of a closet utilizing my invention.

Similar reference numerals refer to similar parts throughout the several views.

Referring now .to Fig. l, a wall plate 1 -is illustrated which is preferably of rectangular or other polygonal configuration. The plate 1 is tapped at Z for threaded'ly engaging a soil pipe nipple 14 (see Fig. 2 The four edges of the plate are tapped as at 3 for purposes of having the upright supporting arms 4 attached thereto by means of the bolts 5. It will be noted that by tapping all four edges of the wall plate 1, the carrier will be in proper position for complete assembly on approaching the wall surface after every quarter turn of the plate on the soil pipe nipple. It should be understood that the ability of the plate to properly position with every quarter turn presents a novel and distinct advantage in that a close and more eflicient adjustment is possiblerelative to the finished wall.

The supporting arms 4 are provided with tapped holes 6 for threadedly engaging studs 7 which are the means for supporting the closet 13 as shown in Fig. 3. The washers and cap nuts 17 which threadedly engage the termini of the studs 7 firmly secure closet 13 in position.

ice

The arms 4 are also provided with drilled holes '8 shown in Fig. 3 for purposes of assembly to the wall plate 1 by means of the boltsS. The lower portion of the .supporting arms 4 are obliquely tapped asat' 9for threadedly engagingheadless set screws 11. It isthe action of the termini of these screws lbearing against the surface of the angle iron 12 or other fixed'abutment'behind'the wall which transmits the stress o'fLthe suspended closet from the carrier as shown in Figs. '2 and 3. In addition, the screws ll provide stability of the entire assembly as rotation of the closet and attached carrier about'the threads of the soil pipe nipple 14 is prevented by their opposed positioning, as is clearlydepictedin Fig. 2.

Referring now particularly"toFig. '3, .a closet bowl 13 is'illustrated,.partly in section, utilizing my-invention. The wall plate '1 is depicted threadedly engaged to the soil pipe nipple :14, which .is in 'turn threadedly engaged to the soil pipeffitting 20. Interposedbetween the nipple 14 and'the end surface '15 "of :the closet "13, the gasket 16 made of rubber orother'suitable'gasket'material is positioned. It will be noted that the end surface 15 and the flange portion 18 of the closet 13 define a recess .19 for receiving'the entire carrier assembly. The closet flange portion 18 conceals the carrier from view in the final assembled position, therebypresenting a pleasing appearing closet design which is substantially close to the wall W at its end limit. 7

Particular attention 'is now directed to the supporting headless set .screws 11 which penetrate the wall W through the'oblique passages 21. .As illustrated, the end limits "of the screws '11 'bear against the angle "iron 12 which is maintained in a stationary position behind the Wall W by means of the screws 22 which fasten the iron 12 to the floor F. It is, of course, obvious that any equivalent means may be substituted for the angle iron 12, such as a recessed block positioned behind each wall passage 21, 'which'wil'l function to similar advantage.

From Figs. 1 and 2, it is apparent that the oppositely disposed positioning of the screws 11 on the supporting arms 4 will prevent any applied force on a side edge of the bowl :13 from causing the bowl and attached carrier to revolve about the waste pipe threaded connection at '2.

Prior to final assembly of the closet 13 to the carrier by means of the studs 7 and cap nuts 17, the supporting arms 4 and attached wall plate 1 are set in fixed relation to the angle iron 12 by adjusting the supporting screws 11. The adjustment comprises the simple act of advancing .the screws 11 through the tapped holes 9 by means of a screw driver until the screw ends are firmly po'sitioned against the angle iron 12. The closet bowl 13 is then firmly secured to the supporting arms 4by means of the studs '7 which pass through the holes 23 of the closet bowl. The washers 10 and cap nuts 17 are then assembled to the ends of the studs 7.

From Figs. 2 and 3, it will be noted that the downward thrust imparted to the carrier by the closet bowl 13 is reacted to and negated by the set screws 11 reacting on the angle iron 12. Consequently, a stable, secure assembly is efiected employing my carrier with an ease of installation heretofore unknown.

It should be appreciated'that by utilizing my invention no final adjustment behind the wall is necessary. The edge of the angle iron 12, or other fixed abutment, is positioned immediately behind the finished wall beneath the soil pipe nipple 14 and may therefore be easily installed on the floor surface prior to the erection of the finished wall W. After the erection of the wall W, the set screws 11, as previously described, are made to bear against-the angle iron 12. This simple adjustment is performed from the outside of the wall and obviates any necessity for adjusting a soil pipe support or other reinforcing means behind the wall W.

It should be further noted that the carrier assembly may be advantageously employed with a blow-out type closet bowl. Since the soil pipe connection would of necessity be positioned higher relative to the floor than in a siphon closet installation as hereinabove described and illustrated, the supporting arm members would be attached to the Wall plate at their upper extremities. It would therefore be possible to have supporting arms which would work equally well on blow out and siphon type closet bowls by merely obliquely tapping both ends of the supporting arms to engage the supporting set screws. Corr sequently, whether the wall plate is attached to the upper or lower extremity of the supporting arm would be immaterial since the set screws may be inserted and will perform their supporting function in either Wall plate position.

Thus, I have presented in the illustrated designs a wall hung closet carrier in which the final adjustment of the carrier is simply and efiectually made on the outside of the finished wall eliminating the necessity of working in confined walled-in spaces. In addition, elficient distribution of the downward thrust of the suspended closet to the fioor behind the wall is efiected with no stress imposed on the wall W itself. The set screw members transmitting the downward thrust perform the secondary function of stabilizing the closet bowl 13 against any revolution occasioned by a moment of force about the spoil pipe connection resulting from a weight applied to an edge of the closet bowl. Thus, a secure closet assembly is assured.

It is, of course, obvious to those skilled in the art that numerous substitutions and changes may be made in the details of the construction revealed without departing from the spirit of my invention as determined by the appended claims.
