GHEGK VALVE.
No.-314;107. Patented Mar.17,1885.
UNITED STATES PATENT OFFICE.
WILLIAM OHAPPELL, OF CHICAGO, ILLINOIS.
CHECK- SPBCIEICATION forming part of Letters Patent No. 314,107, dated March 1'7, 1885.
Application filed Mgrch 6, 1884. (No model.)
To all whom it may concern:
Be it known that I, WILLIAM CHAPPELL, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented a certain new and Improved Check-Valve; and I hereby declare the following to be a full, clear, and exact description of the same.
My invention is designed particularly for use with bath-tub and water-closet wastepipes, where these are connected, to afford a back-water valve. It frequently happens thatv the large quantity of water which enters a closet soil-pipe does not pass off as fast as supplied, and seeks an outlet through the pipe leading to the bath-tub, introducing into the latter water mixed with matter of the water closet. The connection also affords a means of escape by way of the bath-tub, for gases arising from the sewer. It is the object of my invention to obviate these diflriculties; andto this end my invention-co1nprises a check-valve of peculiar construction located within one waste-pipe leading to another waste-pipe, whereby the waste in the one shall pass without obstruction into the other, the passage remaining closed, however, when the flow is in the opposite direction.
In the drawings, Figure 1 is a longitudinal vertical section of a bath-tub and water-closet provided with my improvement; Fig. 2, a 1on gitudinal vertical section of my improved valve; and Fig. 3 a plan view of a detail.
A is a bulb provided with a tubular extension, t, at one end, the opening at the opposite end being beveled, and provided with a flange, s, slanting in the-direction of the opening, but bent at its upper and lower edges in opposite directions, to form right angles with the bulb A and extension t, as shown at s in Fig. 1, and provided with bolt-holes.
A is a straight tube, of narrower dimensions than the bulb A, and having the opening at one end beveled to coincide with the beveled opening in the bulb, being also provided with the flange q, producing aninternal shoulder, and formed in the manner described ofthe flanges. The detailshownin Fig.
VALVE.
3 represents the device for forming the valve B,being located for that purpose between the parts just described, and held between the flanges, the right angular portions. of which assist in producing a tight joint, the parts being joined together by means of bolts passing through the bolt-holes provided, as described, in the flanges s and q, and also inthe valve B, as shown at x in Fig. 3.
The part B comprises a disk, preferably of rubber, of dimensions sufficient to cover the adjacent openings in the bulb A and tube A and the inner adjacent faces of the flanges ,s and q.
A flap, O, of oval shape, is cut, extending partway around thecenter of the disk, leaving it connected at its top to operate as a hinge. A portion of the material of the flap G is cut away around the edges to provide an opening, y, and leaving the flap of dimensions greater than those of the opening to the tube A, but less than thoseof the opening to the bulb A. A plate of metal, 10, afford ing a strengthening medium and a weight for the flap, is secured upon one face of the latter by means of abolt, o, passing through the flap and plate and nut o.
It will be understood from the foregoing description of the construction that the flap O can be swung upon its hinge into the bulb A, being of dimensions smaller than the same, but being larger than the openingof the tube A, it will, when forced toward the same, abut against its edges and close the entrance in that direction.
The connection with the bath tub D is made in a. manner to permit free flow of the water from it through its waste-pipe a into the soil-pipe m of the water-closet E by opening the flap G into the bulb A. Nothing can pass in the opposite direction from the soilpipe mon account of the barrier formed by the abutment of the flap 0 against the edge of the opening in the tube A and the inner face of the flange q.
What I claim as new, and desire to secure by Letters Patent, is-
A valve to be inserted in a waste pipe leading from a bath-tub to a watercloset,
comprising in combination the following elements, viz: a bulb, A, provided at one end with atubular extension, t, and with aflainge, s, at the opposite end, a tube, A, of narrower dimensions than the bulb A, and provided with a flange, q, a disk, B, of pliable material, secured between the flanges s and g, which are secured together, and a flap,'O,
formed by cutting part Way around the center of the disk B and hanging at one end from 10 the same, all being constructed and arranged to operate substantially as described.
