S. C. QUALHEIM ET AL 'FLUSH TANK DRIP PAN Filed May 27, 1948 INVENTORS SVERRE COUALHEIM HAROLD J.QUA1 HEiM Patented May 30, 1950 FLUSH TANK DRIP PAN Sverre C. Qualheim and Harold J. Qualheim, Racine, Wis.

Application May 27, 1948, Serial No. 29,488

1 claim. 1

Our invention refers to drip pans for toilet flush tanks. The primary object of our invention is to provide a light weight exteriorly ribbed pan having transverse throat slots therein for the reception of the flush pipe and supply pipe of the tank. The pipe throats are ribbed and shouldered for the reception of interlocked drain covers and we provide a plurality of adjustable cups whereby the pan is detachably secured to the bottom of a tank without the aid of a skilled mechanic.

With the above and other objects in View, which will appear as the description proceeds, the invention resides in the novel construction, combination and arrangement of parts, substantially as hereinafter described, and more particularly defined by the appended claim, it being understood that such changes in the precise embodiment of the herein disclosed invention may be made as come within the scope of the claims.

In the accompanying drawings is illustrated one complete example of the physical embodiment of the present invention constructed according to the best mode so far devised for the practical application of the principles thereof.

In the drawings:

Figure 1 represents a plan view of a drip pan embodying the features of our invention, parts being broken away and in section to more clearly illustrate structural features.

Figure 2 is a longitudinal sectional view through the pan, the section being indicated by line 2-2 of Figure 1.

Figure 3 is a cross section of the same, the section being indicated by line 33 of Figure l.

Figure 4 is another cross section of the same, the section being shown upon a, plane as indicated by line 4 4 of Figure 1.

Referring by characters to the drawings, l indicates a rectangular drip pan which may be stamped from light material or molded preferably of aluminum material.

The edges of the pan are provided with an upstanding rib I and the bottom of the pan, as best indicated in Figures 3 and 4 of the drawings, is inclined forwardly for draining purposes. The front rib portion is formed with a drain gutter 2 which is flared towards the center of the pan and said gutter has molded therein a centrally disposed nipple 3 for the reception of a small nexi- 2 ble drain pipe 3 which may be conveniently inserted within the toilet bowl.

'I'he rear side of the pan is 'provided with a pair of transversely disposed throats 4-4 terminating with semi-circular ends for the reception,

as indicated in dotted lines, of the flush pipe A and the supply pipe B, which pipes communicate with the flush tank, not shown.

As best shown in Figure 2 o f the drawings, the bottom of the pan, as a whole, is downwardly inclined towards the center whereby drainage is effected in conjunction with the gutter 3.

The pipe receiving throats which interrupt the rear flange of the tank, are provided with upstanding lips 5-5, which lips are shouldered with reference to their point of intersecting with the rear rib portion I and said lips are also provided with shoulders 5 intersecting the circular base portion of the lips, for the purpose of receiving and interlocking a pair of removable caps 6 6'. The caps serve to close the throats and the same are preferably crowned for drainage purposes and the longitudinal edges thereof are formed with depending flanges 1 1.

The caps at their inner ends are semi-circular in form to coincide with the semi-circular base of the pan throats whereby the water pipes are encased.

In order to adjust the pan to the bottom of a flush tank, not shown, we provide the bottom of said pan with a series of threaded Shanks 8, the same being molded within the bottom surface of the pan.

The Shanks, having adjustably fitted thereto, bosses 9 terminating with vacuum cups 9', the same being formed from any suitable exible material such, for example, as rubber or the like.

The cup shanks 8 extend in pairs from the bottom of the tank at the front and rear portion thereof, and due to the adjustability of the bosses of the cups upon the shanks 8, the angle of the pan may be varied with reference to the discharge nipple, which angle in many cases must be varied due to the fact that such pans are attached to old flush tanks, the same being sagged due to age of the installation.

By this simple construction, the pan may be adjusted to the bottom of a tank by those unskilled in the art of mechanics whereby the series of cups will firmly adhere to the bottom of the 3 iiush tank and in conjunction with their adjustability the drain angles of the pan may be Varied.

After such adjustment of the pan to the tank, the caps 6--6' are simply dropped into place over the lipped throats of said pan whereby the caps are rrnly held in their proper positions with relation to the drip pan and associated parts, it being noted in Figures 1 and 2 of the drawings, that the rear crowned ends of these caps are formed with tapered beads E, which beads serve to engage the interrupted rear ribbed portion I so as to insure that all drainage from the tank Walls will be directed into the drip pan.

We claim:

In a dripv pan attachable to the bottom of a iiush tank, having throats for the reception of the water supply, flush pipes and a drain nozzle means for adjustably securing the pan to the tank bottom, comprising a pair of front and rear threaded Shanks, vacuum cups having bosses engageable with the threaded shanks, the cups being rotatably adjusted upon the shanks to increase or decrease the length of the cups relative to the pan bottom, whereby the angle of the pan is varied, with reference to its drain nozzle.
