TOILET BOWL ATTACHMENT MEANS 2 Sheets-Sheet 2 ATTORNEY United States Patent 3,125,765 TOILET BOWL ATTACHMENT MEANS Allyn C. Fay, 9 3rd St., Springfield Gardens, NY. Filed May 23, 1962, Ser. No. 197,112 Claims. (Cl. 4-252) This invention relates to toilet bowls and is particularly directed to a toilet bowl used in conjunction with a flush tank.
It is primarily directed to an adjustment means provided in the toilet bowl and the flush tank, to enable the toilet bowl to be moved through a specified range in various directions relative to a lead bend or discharge tube, which is connected to the horn of the toilet bowl.
A primary feature of the invention is that the trapway of a vitreous china toilet bowl is formed of a constant diameter, which is considerably smaller than the lead bend or discharge tube, which is connected to the horn of the trapway of the toilet bowl, thus enabling one size of toilet bowl to be adjusted relative to the wall adjacent which the toilet bowl is mounted, thereby substituting one adjustable toilet bowl for several stock sizes of toilet bowl.
Another feature of the invention is that space is provided around the discharge or horn end of the trapway of a toilet bowl to enable the toilet bowl to be moved along either an axis aligned with the longitudinal axis of the toilet bowl or along any other axis, the degree of movement of the toilet bowl being controlled by the diameter of the horn of the trapway relative to the diameter of the lead bend, as well as the cross-sectional contour of the horn or discharge end of the trapway, and the size of the lead bend or discharge tube, to which the horn of the toilet bowl is fitted.
Another feature of the invention is that a plurality of adjustable mounting bolts is used to attach the base flange of the toilet bowl to a support flange which is attached to the lead bend or discharge tube, thereby clamping the toilet bowl to the support flange in any adjusted position.
Another feature of the construction is that the base flange of the toilet bowl has means formed therein operative to receive a plurality of threaded studs each of which is integral with one of the adjustable mounting bolts, to clamp the base flange of the toilet bowl to the support flange of the lead bend in the adjusted position.
Another feature of the invention is that the support flange attached to the lead bend has a plurality of radially positioned slots of arcuate contour therethrough, each of which is adapted to adjustably receive the cylindrical body of one of the mounting bolts, thereby providing a wide adjustment between the base flange of the toilet bowl and the support flange attached to the lead bend.
A primary object of the invention is to provide a single adjustable toilet bowl to be used in placed of two or more selected sizes of toilet bowl to compensate for variations in spacing between the finished wall surface adjacent which the toilet bowl is mounted, and the lead bend or discharge tube and the support flange attached thereto.
Another object is to provide a plurality of adjustable mounting bolts, to clamp the mounting flange of the toilet bowl and the support flange attached to the lead bend, or discharge tube, to compensate for variations in location between the toilet bowl in which the outlet or horn end of the trapway of the toilet bowl is mounted. The mounting bolts are so constructed that the toilet bowl may be moved in several directions through a predetermined range to compensate for variations in spacing and location between the lead bend or discharge tube and the finished wall, adjacent which the toilet bowl is mounted.
The accompanying drawings, illustrative of one embodiment of my invention, and several modifications thereof, together with the description of their construction and the method of operation, mounting, adjustment and utilization thereof, will serve to clarify further objects and advantages of my invention.

FIG. 7 is a front elevational view, similar to FIG. 4, of a modification of the mounting bolt shown in FIG. 4, showing variations of the clamping stud, and the connecting section connecting the two clamping portions of the mounting bolt to one another.
It will be understood that the following description of the construction and the method of operation, adjustment, mounting and utilization of the toilet bowl and adjustable attachment means therefor is intended as explanatory of the invention and not restrictive thereof.
In the drawings, the same reference numerals designate the same parts throughout the various views, except where otherwise indicated.
One embodiment of the construction shown in FIG. 1, shows a vitreous china toilet bowl 15, with tank 16, attached to the upper end of the toilet bowl.
The lower end of the toilet bowl has a base flange 17 integral therewith, the base flange having a substantially circular base wall 19 integral therewith, as shown in FIG. 3.
The lower right-hand portion of the toilet bowl has a trapway 21 integral therewith, the trapway being generally of circular or other suitable cross-section, the upper end of the wall of the trapway being in the form of a baffle or weir 22, the upper end of which determines the level 23 of the Water 24 in the toilet bowl 15.
The lower or discharge horn 25, of the trapway, which is integral with the top wall 26 of the base flange, is of circular or other suitable cross-section, as shown in FIGS. 1 and 3, the outer diameter of the discharge horn of the trapway being considerably smaller than the diameter of the lead bend or discharge tube 27, shown in FIG. 2, to provide an adjustment between the lead bend and the horn of the toilet bowl, as shown in FIGS. 2 and 3, and hereinafter described in greater detail. The inner diameter of the trapway 21 is limited by code regulation to a diameter which allows a one and half-inch diameter solid ball to be passed therethrough. As shown in FIGS. 2 and 3, the outer diameter of the discharge horn or dis charge end 25 of the trapway, is equal to or less than onehalf the inner diameter of the lead bend or discharge tube 27, to which it is fitted. This provides an adjustment in any radial direction which is equal to or greater than the outer diameter of the discharge end of the trapway, relative to the discharge tube to which the discharge end of the trapway is fitted.
As the trapway forms an integral part of the toilet bowl, this enables the entire toilet bowl to be moved through a distance substantially equal to the outer diameter of the discharge end of the trapway, to take up any misalignment between the discharge end of the trapway and the discharge tube or lead bend 27.
In the construction shown in FIGS. 2 and 3, the inner diameter of the discharge horn of the trapway is approximately 1% inches in diameter, which with an outer wall thickness of one-quarter inch, which is also controlled by regulation, the outer diameter of the discharge horn of the trapway limiting the degree of adjustment between the horn of the trapway of the toilet bowl, and the discharge tube 27 or lead bend in the manner hereinafter described.
A water supply tank 16 is mounted on top of the upper flange 31 of the toilet bowl, the bottom wall 30 of the flush tank having a water discharge opening 32 therethrough which connects with a mating opening 33, formed in the upper flange of the toilet bowl, the opening through the top flange of the toilet bowl being in direct communication with a tapered syphon section 34, which is normally filled with air when a flush ball 35, which is fitted to the interior of the tank and which normally seals the opening 32 through the bottom wall of the tank 16, is moved out of engagement with the opening 32, through the bottom wall of the water tank, thereby allowing flush water to flow from the tank to the body of the toilet bowl through the syphon area 34 thereof.
An opening 37 is cut through the inner wall 38 of the toilet bowl, at the lower end of the syphon section, the opening 37 which is normally sealed by the water in the center of the toilet bowl, allowing the water from the supply tank, to enter the interior of the toilet bowl, through the syphon section 34, thereof.
When the flush ball 35 is elevated, thereby opening the discharge opening 32, through the bottom wall 30 of the tank, water under pressure from the interior of the tank is released through the syphon section 34 of the toilet bowl, thereby elevating the level of the water in the toilet bowl above the normal level 23 shown in FIG. 1, the water and the refuse material being deposited in the toilet bowl, the water 24 and the refuse material being discharged above the weir of the trapway, thence through the trapway 21, through the horn at the discharge end of the trapway, thence to the discharge tube or lead bend located below the toilet bowl.
As shown in FIG. 1, an inner wall 39 of arcuate crosssectional contour is integral with the right-hand portion of the toilet bowl, the inner wall being sloped at a relatively shallow angle relative to the top surface of the flange of the toilet bowl, the lower end of the inner wall having a baflle integral therewith, the bafile extending below the nominal water line 23, thereby controlling the direction of flow of the Water from the interior of the toilet bowl, toward the baflle, or weir 22 of the trapway, thence through the trapway 21 to the discharge end or horn thereof, at the bottom of the trapway.
In order to support the toilet bowl in the adjusted position shown in FIGS. 2 and 3, a support flange 42 is attached to the upper end of the lead bend 27, or discharge tube. The flange includes an inner wall 43 which is of circular cross-sectional contour following the cross-sectional contour of the lead bend or discharge tube, the inner wall 43 of the flange being fixedly attached to the outer diameter of the lead bend 27, or discharge tube. A substantially flat top wall 44, integral with the inner wall of the flange extends from the inner wall to a substantially circular outer wall 45, which is co-axial with the inner wall andsubstantially perpendicular to the top wall of the support flange 42.
An annular gasket 46, formed of wax, or other suitable compressible material, is inserted between the top wall 44 of the support flange 42, and the inner surface of the top wall 26 of the base flange 17 of the toilet bowl 15, which is substantially parallel to the top wall 44 of the support flange.
As shown in FIG. 3, a plurality of equally-spaced parallel- faced cutouts 47, 47a of arcuate contour is cut through the top wall 44 of the support flange to clear the body 48, 48a of the cylindrical head end of an adjustable mounting bolt 49, 49a, which is provided to clamp the support flange 42 to the base flange 17 of the toilet bowl.
In the construction shown in FIG. 3, there are three equally-spaced arcuate slots 47, 47a through the top wall 44 of the support flange, the number of slots corresponding with the number of adjustable mounting bolts 49, 49a fitted between the base flange 17 of the toilet bowl and the support flange 42 attached to the lead bend or discharge tube 27.
In order to allow a relatively flat oval head 51, 51a integral with each of the adjustable mounting bolts 49, 49a to pass therethrough, an oval slot 52, 52a which is directly connected with one end of each of the parallel-faced slots 47, 47a, is cut through the top wall of the support flange 42. This auxiliary oval slot 52, which is in direct communication with each of the parallel-faced slots 47 through the top wall of the support flange 42, allows the oval head 51 of one of the mounting bolts 49 to be inserted therethrough, the arcuate slots 47, 47a allowing the cylindrical connecting or body section 48, which is integral with and connects the head 51 of the mounting bolt, with the parallel-faced oval connecting flange or spacer section 55, of each mounting bolt, to be moved from the oval cut-out at one end of each arcuate slot to the required mounting position of the base flange 47 of the toilet bowl relative to the support flange 42 attached to the lead bend 27.
As shown in FIGS. 2 and 3, the top wall of the base flange has a plurality of substantially circular openings 56 therethrough to clear the stud end- s 54, 54a of the mounting bolts 49, 49a, the number of openings 56 corresponding with the number of mounting bolts 49, 49a used to clamp the base flange 17 of the toilet bowl, to the support flange 42 attached to the lead bend 27 or discharge tube.
When the toilet bowl 15 is moved to the mounting position, such as that shown in FIG. 3, relative to the support flange 42 attached to the lead bend, the location of which is fixed relative to the wall 60 adjacent which the toilet bowl is mounted, the toilet bowl is first held in a position in which the upper wall 26 of the base flange 17, of the toilet bowl clears the top of the studs 54, 54a of the mounting bolts. After the toilet bowl is in this position, the mounting bolts 45!, 49a are moved along the arcuate slots 47, 47a through the top wall of the support flange 42, until the studs 54, 54a of the mounting bolts are substantially aligned with the mating openings 56, 56a through the top wall 26 of the base flange 17 of the toilet bowl 15.
After the studs 54, 54a of the mounting bolts 49, 49a are aligned with the openings 56, 56a through the top wall 26 of the base flange 17, the toilet bowl and the base flange 17 thereof are dropped into a position substantially as shown in FIG. 2, in which the studs 54, 54a integral with the mounting bolts 49, 49a pass through the openings 56, 56a through the top wall 26 of the base flange.
Before the toilet bowl 15 is moved into the mounting position shown in FIGS. 2 and 3, a wax gasket 46 such as that shown in FIG. 2, is inserted above the support flange 42, between the top wall 44 of the support flange 42 and the under surface of the top wall 26 of the base flange of the toilet bowl.
With the wax gasket in place relative to the support flange 42, the toilet bowl is dropped until the cylindrical studs 54, 54a integral with the mounting bolts 49, 49a pass through the openings 56, 56a through the top wall 26, of the base flange 17, thereby compressing the wax gasket 46, located between the top wall 26 of the base flange 17 and the under surface of the top wall 44 of the support flange 42. The wax gasket, which is made of relatively soft compressible material is compressed by the top wall 26 of the base flange. It is also distorted to some extent where the gasket engages the various sections of the mounting bolts 49, 49a, as shown in FIG. 2.
A washer 58, is fitted to each of the studs 54, 54a of the mounting bolts, after which a nut 59, 59a, is threadably fitted to each of the studs 54, 54a of the mounting bolts, the nuts 59, 59a being threadably moved downward relative to the studs 54, 54a, until they clamp the top wall 26 of the base flange 17, to the top wall 44 of the support flange 42, thereby rigidly supporting the toilet bowl relative to the support flange 42 attached to the lead bend 27 or discharge tube, the position of the toilet bowl, relative to the lead bend or discharge tube 27, being dictated by the relation between the finished wall 60, adjacent which the toilet bowl is mounted, and the center of the discharge tube 27 or lead bend which is located in a fixed position relative to the unfinished wall. This position will be changed to some extent relative to the lead bend or discharge tube 27, after the wall is finished by plastering, or other suitable finishing means.
As shown in FIG. 3, the base flange 17, of the toilet bowl 15 may be moved longitudinally outward, in a direction perpendicular to the wall 60 adjacent which the toilet bowl is mounted, or it may be moved through any angular direction relative to the axis of the lead bend 27 or discharge tube, depending upon the required mounting position of the toilet bowl 15 relative to the lead bend, or discharge tube 27 and the support flange 42 attached thereto, which are fixed relative to the wall 60 adjacent which the toilet bowl is mounted.
The position of the individual mounting bolts 49, 49a, 4% relative to the arcuate slots 47, 47a through the top wall 44 of the support flange 42 is determined by the relation between the axis of the base flange 17 of the toilet bowl 15, relative to the axis of the support flange 42 attached to the lead bend or discharge tube 27.
This applies also to the angular relation between each of the connecting flanges of each of the mounting bolts 49, 4%, relative to the face of the wall 60 adjacent which the toilet bowl 15 is mounted. These vary with the relative position between the axis of the toilet bowl 15 and the axis of the support flange 42, which is attached to the lead bend or discharge tube, which supports the toilet bowl.
The upper section of the toilet bowl, adjacent the upper flange 31 of the toilet bowl, located near the left-hand end thereof as shown in FIG. 1, includes a top wall 62, and a substantially parallel lower wall 63, spacedly located relative to the top wall, a clear area 64, being formed between the top wall and the parallel lower wall, as shown in FIG. 1, the top wall and the lower wall 63 parallel thereto surrounding the syphon section 34 of the toilet bowl 15.
The parallel lower wall 63 at the upper end of the toilet bowl 15 has one or more small discharge openings 65 therethrough, to allow any water pocketed in the clear area 64 between the top wall and the lower wall to be discharged therethrough into the center of the toilet bowl.
As shown at the right-hand end of FIG. 1, the upper portion of the toilet bowl shown in FIG. 1, has a head section 66, of oval cross-sectional contour, which follows the oval outer contour of the top of the toilet bowl, integral therewith.
The interior of the oval head section at the top of the toilet bowl has a closed cavity 67, of oval cross-sectional contour in the center thereof.
The lower wall of the head section 66 at the top of the toilet bowl, has a plurality of angularly positioned discharge openings 68 therethrough, the discharge openings being operative to allow any water collected in the closed oval cavity 67 to be discharged therethrough into the interior of the toilet bowl 15.
FIG. 7 shows a modification of the adjustable mounting bolts shown in FIGS. 4, 5, and 6. In this construction each mounting bolt consists of a head 90, of oval or other suitable contour, the head being integral with a cylindrical body section 91, the opposite end of which is integral with a cylindrical or other form of elongated connecting section 92, which connects the head 90 and the body, with an externally threaded cylindrical stud end 93, which is substantially the same as the stud end of the mounting bolt shown in FIG. 4.
In all other respects, the modified mounting bolts shown in FIG. 7, are substantially the same as those shown in FIGS. 4, 5 and 6, the mounting bolts being used interchangeably with those shown in FIGS. 4, 5 and 6.
The primary advantage of the toilet bowl construction shown in FIGS. 1, 2 and 3, is that a single adjustable toilet bowl can be substituted for several standard sizes of toilet bowls.
Thus, where a 4-inch inside diameter lead bend is roughed in through a distance of from 10 /2 to 13% inches from the rough wall surface, -a single toilet bowl having an adjustment range of 1%" in either direction, along the longitudinal axis of the toilet bowl can be utilized in place of several sizes of toilet bowl.
Thus, instead of warehouses stocking several sizes of toilet bowls, as for example 10 inch, 12 inoh, and 14 inch, the above sizes representing the distance between the surface of the finished wall tand the center of the base flange of the toilet bowl, a single nominally 12-inch adjusta ble toilet bowl can be substituted for a range of sizes of toilet bowl.
This also tends to reduce the installation time for installing a toilet bowl, by a wide margin, as it avoids the necessity for making a special trip to the warehouse for a replacement toilet bowl in another size, when the installer discovers, while installing a toilet bowl, that the distance from the finished surface of the wall to the center of the base flange of the toilet bowl is not at the correct distance to fit into the discharge tube or lead bend 27. It is then necessary to either replace the toilet bowl by another size, or adjust the position of the center of the lead bend [relative to the finished wall.
Where local building codes permit the use of a 3-inch inside diameter lead bend or a 3-inch inside diameter copper waste tube in place of the 4-inch diameter lead bend, the adjustable toilet bowl can be utilized without altering the toilet bowl in any manner whatever. With the conventional type of toilet bowl, it is necessary to utlize an expansion tube to expand the inside diameter of the tube from 3 inches to the four inches to receive the horn of the convention-a1 toilet bowl.
While the range of adjustment is reduced with a 3-inch diameter tube, the reduced adjustment range is still 1% inches in either direction, thus allowing a single toilet bowl to take up the adjustment required in most lead bend or copper water tubing installations.
The advantage of the washdown toilet bowl fitted with a continuous diameter trapway, as shown in FIGS. 1, 2 and 3, over other types of toilet bowls is substantially as follows:
This type of toilet bowl will exert more pressure during the flushing operation and therefore dispose of the waste material more effectively and in less time than the conventional type of Washdown toilet bowl.
Assuming a 6 gallon flush tank, the total weight of the water in the flush tank is 50 pounds, assuming 8 /3 pounds per gallon, as the weight of the water in the tank.
Pressure exerted by the total amount of water in the tank, or approximately 50 pounds, is released against the air trapped in the syphon of the toilet bowl shown in FIG. 1. The air in the syphon is compressed by this water pressure, in the lower portion of the syphon assist or jet hole at the lower end of the syphon shown in FIG. 1. This jet of air creates a partial vacuum at the bottom of the water seal of the toilet bowl. The normal atmospheric pressure of 14.7 pounds per square inch on the top surface of the water in the toilet bowl works against this vacuum. The atmospheric pressure is exerted on the entire top surface of the water in the toilet bowl, the area of which is considerably greater than the relatively small area in the syphon in which the vacuum is formed.
The specified water surface on this type of toilet bowl is 9 inches as compared to the washdown type of toilet bowl. The total water surface is therefore 63.62 square inches in this type of toilet bowl, and with atmospheric pressure of 14.7 pounds per square inch, this gives us a total atmospheric pressure on the surface of the water of 945.06 pounds, which is almost 200 pounds greater than the pressure which flushes a washdown type of bowl.
In the toilet bowl and trapway design shown in FIGS. 1, 2, and 3, we obtain full water pressure, so that the compacted waste and the paper deposited in the toilet bowl completely pass through the horn or discharge end of the trapway, shown in FIGS. 1, 2 and 3. With the combination of improved horn and trapway design, the offset floor flange bolts, shown in FIGS. 2 and 3, and the adjustment feature of the tank bowl connection, shown in FIGS. 11 and 12, we obtain a sharp and obvious improvement from an operating and installation standpoint over the conventional type of toilet bowl, and tank combination.
It will be apparent to those skilled in the art that my present invention is not limited to the specified details described above and shown in the drawings, and that various modifications are possible in carrying out the features of the invention and the operation, adjustment, actuation, and method of utilization thereof, without departing from the spirit and scope of the appended claims.
