l llTliU *rais Ir a-tented Februa y 28! 1905" HENRY J. LUFF, OF CLEVELAND, OHIO.
SPECIFICATION formingpart of Letters Patent No. 783,586, dated 1F ebruary 28, 1905.
Application filed ebruary '7, 1903. Serial No. 142,346.
To (all 'IUII/U'IIZ/ it lit/t7 concern:
Be it known that LHENRYJ. LUFF, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented new and useful lm provements in \VallClearrOut and Hack-Vent Fittings; and .i do declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to a wall clean-out and back-vent litting for sink waste-water connections; and the object of the invention more especially is to provide means for facilitating the cleansing oi the pipes and other parts in sink connections which are back of the trap therein.
It is well known that greasy deposits in wastepipes 'lrom kitchen-sinks are not only constantly and inevitably occurring, but in time such deposits completely clog and lill the waste-passage, so that it becomes completely closed. Sometimes the accumulations gather above and in the air-vent so as to completely close said vent, and thus cause the sink-trap to siphon, which is most deleterious to health when it occurs, because of the opening it atfords for the entrance of poisonous sewergases. Furthermore, the old-style sink connections were devoid oi. such construction as would facilitate or make easy or even practicable the cleansing of the said connections when this became necessary, and hence the present invention. By my invention an opening is provided immediately at the place of danger, whereby a plumber particularly can quickly and effectually deal with the trouble and remove all foreign matter and restore the parts to operating position with small labor and expense.
To these several ends the invention consists in the construction and combination of parts, substantially as shown and described, and particularly pointed out in the claims.
In the accoi'npanying drawings, Figure l is a cross-sectional elevation of a sink-basin and a plan elevation of the waste-pipe and vent connection therewith. Fig. 2 is an enlarged front elevation of the fitting for the backvent and wall clean-out with a portion ot' the cap thereon broken away to show internal constructions; and Fig. 3 is a vertical sectional elevation of said fitting on line .41 m, Fig. 2.
As thus shown, A represents a sink-lmsin, and B the waste-pipe there for, inchuling trap 2 and coi'ipling pipe or section 3, having a threaded coupling or union with the extremity of trap 2. The other end has a threaded connection with boss ion cap (3, screwed into a relatively large opening in the front ol the iitting l). in use the said fitting rests within the wall E, behind the sink, and l plan to bring the taco of cap U about I'lush with the finished surface of said wall, so as to maintain appearances consistent with the other open-plumbing eliects. titructurally and internally the upper open end 6, constituting the vent portion of this fitting. begins practically at the si'ibstantially transverse line 7, which, it will be observed, is above the upper portion of the inlet through cap U and especially above the inlet through pipe 3 in said cap. This is a very important feature in my construction, because it carries the said inlet so far below the mouth oi? the vent at 7 that there is no possibility practically of the water splashing up into said vent, and thereby depositing adhesive matter and gradually lilling up said ventpassage, as formerly. Then, again, it will he noticed, that the mouth proper oi? the vent lying, say, between points (Z and (6, lies at an angle of about lorty-[ive degrees to the face of the front opening in litting D, so that this part of the vent is within easy ac.- cess if for any reason it should become clogged and require cleansing; but the bowl 8 ol the litting is so constructed and the outlet down ward tl'leretrom is so ample that water passes directly down as it l'lOWS in and there is no opportunity for backing of the water into the vent. At the most this cannot occur until the down-pipe is practically lilled up, and this fact will at once liselose itself to the sink.
Then removing the large face-cap U the whole interior ol fitting is laid open,as well as its up and down extremities or portions 6 and 9.
Cap O is preferably provided with an inner hood or extension opposite its central opening to deflect the water downward and more effectually guard against any matter splashing upward into the vent-opening.
It will be seen that the trap 2 and Wall-fitting D are wholly separate and distinct from each other and that the trap is essentially of a self-cleansing variety, being preferably of the so-called 8 pattern. Hence there is no clogging possible therein. Then it is connected with said wall-fitting by means of a removable pipe-joint 3, supported on and connected with trap 2, so that when cleansing of the fitting is to occur said joint is first removed and then the cap 0, whereupon the whole interior of the fitting is laid open to cleansing.
WVhat I claim is" 1. A sanitary fitting for waste water from sinks and the like consisting of a hollow body having a vent-opening inits top and a wateroutlet at its bottom constructed each to make pipe connections and provided with acircular threaded opening at its front, in combination with a removable cap closing said threaded opening and constructed with a threaded opening at its middle and having a downwardlycurved deflector on its back extending substantially across beneath the said vent-opening and wholly apart from the wall thereof, substantially as described.
2. In Waste-water connections for sinks and the like, a trap of substantially the S pattern, in combination with a back vent-wall fitting constructed top and bottom to make up and down pipe connections and having a front opening, a cap to close said opening having a curved deflector on its back extending across the space beneath the vent-outlet from said fitting and apart from the wall thereof, and a detachable pipe-joint 3 connecting said trap and cap, whereby said joint and cap can be removed when said fitting requires cleansing, substantially as described.
itness my hand to the foregoing specification this 31st day of January, 1903.
HENRY J. LUFF.
