(10 is hereinafter referred to as the shield.) 13-43- 13-13 indicate gaskets shaped to beveled top surfaces 2-2A. 12 indicates water flushing chamber. 18 indicates ball check valve in tank 19. 17 indicates water 2,777,137 Patented Jan. 15, 1957 seal in bowl 20. 15 indicates fan. 16 indicates electric motor.
Figure 2: The reference numeral 1 indicates a perspective view of my ventilator. 2 indicates beveled top. 3 indicates the concave channel giving greater area to chamber. 12. 5 indicates air exhaust. Said air exhaust 5 is directly connected to concave channel 3; through 3 to water flushing chamber 12. 10 indicates enclosure structure in position around front or visible part of 1. 11 indicates mounting holes.
4 indicates connection between concave channel 3 and exhaust 5. 7 indicates protruding tubular portion. 6 indicates shoulder.
What I claim and desire to secure by Letters Patent is:
l. The combination with a toilet bowl having an upwardly facing water inlet opening and a flush tank having a flush water tube extending through the bottom thereof, the bowl and tankforming the elements of a closecoupled toilet assembly, of a ventilating fitting which spaces said bowl and tank apart, comprising a flat annular body inserted between said bowl and tank, with the flush water tube extending into the central opening of the body, the upper surface of the body surrounding the opening sloping upwardly and outwardly to the outer circumference of said tubular body and forming a seat .for a bevel washer carried by said flush water tube, a
concave circumferential channel formed in the inner wall of the annular body and extending completely around the side of the opening below the inner termination of said sloping portion, an integral air exhaust tubular portion formed on the outer side of said body and adapted to be connected to an air exhaust vent pipe of a suction producing device, said tubular portion communicating with the concave circumferential channel, the lower portion of the body being of reduced diameter to form a shoulder having the flat, horizontal portion facing downwardly in the axial direction of said opening, and a protruding tubular portion extending into the upwardly facing water inlet opening of the bowl and carrying a bevel washer, the protruding tubular portion and bevel Washer centering and sealing the fitting to said bowl.
2. The combination of claim 1 including a shield for the fitting, said shield including a rectangular structure of sheet material, open on one long side and closed across the top and bottom, the closed top and bottom surfaces being cut out inwardly from the open side and equidistant from the ends to fit about the fitting, the topand bottom surfaces having holes spaced between the cut out portion and the ends and receiving the bolts which secure the flush tank to the bowl.
