FLOOR DRAIN EXTENSION Filed Oct. 2a, 1951 Ill 'I'IH: W1
INVENTOR J v 606m"! United States Patent FLOOR DRAIN EXTENSION John H. Schmid, Erie, Pa., assignor to J. A. Zurn Mfg. Co., Erie, Pa., a corporation of'Pennsylvania Application October 26, 1951, Serial No. 253,389
2 Claims. (Cl. 182-31) This invention relates generally to floor or surface drains and more particularly to an extension or extensions for extending the height of a floor or surface drain to conform to a raised floor level upon the addition of concrete or the like to the floor after the original installation without disturbing the original drain connections.
In remodeling work, thefloor level is often changed by removal or addition of concrete, terrazzo, or other floor finishing material. When conventional floor drainshave been installed in an original floor, it is necessary to remove and relocate the drains or to slope the new floor excessively to the drain aperture. No suitable means has heretofore been provided to raise or lower the level of a floor drain grate to accommodate diflerent floor levels.
It is, accordingly, an object of my invention to overcome the above and other defects in present surface or floor drains and it is more particularly an-object of my invention to provide a surface or floor drain with an adjustable extension or extensions for varying the level of a floor drain which is simple in construction, economical in cost, economical in manufacture, and eflicient in operation.
Another object of my invention is to provide an extension for a floor drain whereby a floor drain may be installed permanently in an initial floor installation and the level thereof raised at alater date without disturbing the original installation.
Another objectof myinvention is the provision of novel means for securing an extension in a floor drain in different vertical positions.
Other objects of my invention will become evident from the following detailed description, taken in conjunction with the accompanying drawings, in which:
Fig. 1 is a vertical sectional view of my novel floor drain showing on the left side the extension in its lowermost position and on the right side of the drawing, the extension in an upper position; and
Fig. 2 is a vertical sectional view of my novel floor drain extension whereby an intermediate extension is added to the drain shown in Fig. 1 when an excessive height change is required.
In a drain, it is desirable to increase the flow of fluid through the drain line extending therefrom and to do this, it is necessary to minimize the entrainment of air with the water which seriously impedes the flow of water through the drain and in the drain line. The flow rate of a fluid varies directly with the square root of the hydraulic head available. My novel drain extension greatly increases the hydraulic head on the waste line as will be apparent from the drawings. By having a deep body provided by my novel extension or extensions and a comparatively deep reservoir, ponding over the waste line but below the grate is possible to allow venting of entrained air which will insure the waste line running full. A greater length of time is given for the air to vent because of the greater length of the drain and the extensions and a lower lineal velocity through drain body results which 2,749,999 Patented June 12, 1956 permits a maximum separation of air from the Water before it enters the drain line.
Referring now to the drawings, I show in Fig. 1 a cylindrical shaped reservatory 1 terminating in a centrally disposed, internally threaded outlet 2 in the bottom thereof for connection to suitable drain piping (not shown). The reservatory 1 has an angularly upwardly, outwardly directed flange 3 intermediate the outer side thereof. The bottom of the flange 3 is adapted to engage a marginal portion of an aperture in a floor for support thereby. The top of the flange 3 is engaged by a mated tapered flashing clamp or clamping ring 4, the bottom 5 of the clamping ring 4 being tapered so that it corresponds to the angularity of the top of the flange 3. The clamping ring 4 is secured to the flange 3 by screwbolts 6 which engage threaded apertures 7 spaced circumferentially around the flange 3. Conventional waterproofing paper or metal flashing 8 is clamped between the clamping ring -4 and the top of the flange 3 of the reservatory 1. The reservatory 1 has laterally extending drain openings 9 for seepage water. I
A cylindrical shaped extension 10is telescopically disposed in the reservatory 1 and it has bossed portions 11 with internally threaded, laterally extending apertures 12 for receivingscrew bolts 13 which frictionally engage the inner side 14 of the reservatory 1 to hold the extension 10 in different vertical positions with reference to the reservatory 1. The upper end of the extension 10 has an inwardly directed peripheral flange 15 for seating a strainer grate 16 and an outwardly directedflange 17 for seating on the upper end 18 of the reservatory 1 when the extension 10 is in its lowermostposition as shown on the left side of Fig. 1 and for firmer anchoring in the floo structure. V
In the-installationof my novel floor drain, it is of particular use in instances where the floor is to be poured of concrete in two or more stages. The reservatory 1 is permanently installed in the base portion of the floor and a waterproofing paper 8 is clampedto the top side of the flange 3'by the clamping ring 4. The extension 10 is then disposed telescopically in the reservatory Land the upper side thereof is leveled at the proposed floor level, the outer surface of the extension 10 tapers :downwardly and inwardly toward the bolts 13, thereby allow ing for leveling of the top of the extension to conform to unlevel floors, and the screw bolts 13 are turned to engage the inner side 14 of the reservatory 1 to hold the extension 10 in a given vertical position with reference to the reservatory 1, after which the floor is poured. When, at a later date, it is desired to add a new floor finish, it is only necessary to chip around the flange 17 and relocate the extension 10 at the desired new level and pour the new floor. It is thus unnecessary to rip out the whole drain and waste line for such a revision.
' The addition of the extension member 10 provides a deep reservatory for water whereby a high head of water forms therein. Inasmuch as the water must pass a substantial distance through the extension member 10 and the reservatory 1 to the discharge outlet 2, substantially all of the air in the water is vented therefrom. Furthermore, because of the great distance that the water must travel through the reservatory 1 and the extension member 10, the time to pass through the reservatory is lowered to permit a maximum separation of air from the water. Thus, the high hydraulic head provided by my novel drain and the substantial elimination of entrained air in the water substantially increase the flow of water through the drain.
Where an excessive or comparatively large vertical adjustment of the drain is required, I provide an intermediate extension 20 as shown in Fig. 2 to take care of the excessive vertical adjustment of the drain. In Fig. 2,
the reservatory 1, the extension 10, and the strainer grate 16 are the same. The only difference is that an intermediate offset cylindrical extension member 20 is inserted between the extension 10 and reservatory 1 in Fig. 1. The extension member 20 has a peripheral seating portion 21 for seating on the top 18 of the reservatory 1 and the extension 10 is telescopically disposed in the upper portion 22 of the intermediate member 20 with the screw bolts 13 engageable with the inner side 23 of the intermediate member 20 to secure the extension 10 in different vertical positions. The lower portion 26 of the intermediate member 20 is telescopically disposed in the upper portion of the reservatory 1 and it has bossed portions 27 with internally threaded apertures 28 for threadably receiving screw bolts 29 which frictionally engage the inner side 14 of the reservatory 1 to secure the member 20 in different desired vertical positions with reference thereto. It will thus be seen that the member 20 may be adjusted vertically with reference to the reservatory 1 and held in a desired vertical position by the screw bolts 29 engaging the inner side 14 f the reservatory 1 and the extension may be adjusted to different relative vertical positions and secured in these different vertical positions by the screw bolts 13 engaging the inner side 23 of the upper portion 22 of the intermediate member 20. This modification of my novel invention will permit a very large amount of vertical adjustment of the drain, and by addition of the intermediate member 20, a much deeper reservatory and, thereby, a much higher head of water forms in this drain so that the water must pass a substantial distance through the extension member 10, intermediate member 20, said intermediate member and said extension member constiuting lengthening members, and the reservatory 1 to the discharge outlet 2 whereby all air is vented from the water and the lineal velocity thereof is increased and the time the water travels at a low velocity is increased to permit a maximum separation of air from the water. The high hydraulic head and the substantial elimination of entrained air in the Water greatly increase the flow through the drain over prior strainers.
It will be evident from the foregoing description that I have provided a novel extension for a surface or floor drain with novel attaching means associated therewith which permits a floor drain of conventional construction to be initially installed in a floor in the first stages of construction thereof and which permits extensions to be added thereto at a later date without disturbing the original installation, which adds to the maximum flow capacity and the hydraulic head of the drain, which minimizes the entrainment of air with the water passing to the drain ine through the drain when the extension is attached thereto, and in which the construction and assembly are very simple and economical.
Various changes may be made in the specific embodiment of my invention without departing from the spirit thereof or from the scope of the appended claims.
What I claim is:
1. A surface drain comprising a drain cup of cylindrical shape having substantially vertical sides, a drain outlet, an outwardly extending flange having the top surface thereof sloping upwardly and outwardly disposed intermediate the height of said drain cup attached to the outer periphery thereof, a flashing clamp comprising a ring wedge shaped in cross section adapted to be secured to said flange and to clamp a flashing material therebetween with the top surface of said flashing clamp ring substantially flush with the top surface of said flashing, a hollow cylindrical lengthening member telescopically disposed in said drain cup, laterally extending screw bolts extending through threaded apertures in the sides of said lengthening member, said bolts frictionally engaging the inner surface of said drain cup for securing said lengthening member in different vertical positions relative to said drain cup, and means on the top of said lengthening member to support a strainer grate.
2. The surface drain recited in claim 1 wherein said means to support a strainer grate comprises a hollow cylindrical extension telescopically disposed in said lengthening member, and screw bolts provided through the sides of said extension to frictionally engage the inner periphery of said lengthening member whereby said cxtension may be selectively disposed in a plurality of vertically adjusted positions in said lengthening member.
