WILLAM E. DELEHANTY, OF NEW YORK, N. Y.
SEALING-GAF l FOR SOIL-PiPES.
SPECIFICATION forming part of Letters Patent No. y#59,081, dated May 3, 1904. Application led August 8, 1903. Serial No. 168,735. (No model.)
To f//ZZ 1r/'hmm it may con/cern,.-
Be it known that LVVILLIAM E. DELEHANTY, a citizen of the United States, residing in New York city, county of New York, State of New York, have invented certain new and useful Improvements in Sealing-Caps for Soil-Pipes; and I do hereby declare the followingl to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to the temporary closing or sealing of the upper ends of soil-pipes, either before the closet-bowls have been installed in a building and when it is desired to test the pipe system or protect it against obstructions inserted by malicious or careless persons or when for any reason after instal lation one or more of the bowls or all of them have been temporarily removed.
In the accompanying drawings, Figure l represents a perspective View of a soil-pipe sealed in accordance with my invention. Fig. 2 represents a vertical section thereof.
Similar letters of reference indicate similar parts in both views.
Referring to the drawings, A indicates a water-closet soil-pipe having' an expanded or flaring upper portion L extending, as usual, up through the flooring and surrounded by the plate B. The plate B constitutes one of the elements of the closing or scaling device and is provided with a central opening having a beveled flange Y), whose upper and inner edge makes a knife-edge contact with the proximate wall of the soil-pipe. lt is alsoprovided with lugs c, having screw-threaded apertures which receive the corresponding screwthreaded ends of pins d. The pins d pass freely through openings in lugs e of a coverplate C andare screw-threaded at their upper ends to receive the clamping and tightening nuts f. The cover-plate O has a downwardly and outwardly flaring tubular conical projection 72., adapted to enter the top of the soil- V pipe. About this projection is located a groove e', containing an elastic packingring 71:, preferably of soft rubber. This ring rests securely in the groove and is adapted to be strongly compressed, so as to be forced well down into the V-shaped opening' between the tubular projection and the Haring mouth of the soil-pipe when appropriate tension is put upon the nuts.
By the employment of this device the plumber is enabled to readily and effectual] y seal all of the soil-pipes of a building' before the closets are installed in such manner that al] of the usual peppermint, water, and other tests may be carried on and so that the building itself is protected from sewer-gas iniiltrations at any time when it is necessary to remove or replace a closet bowl or bowls.
1t will of course be understood that Fig. 2 represents the closure just before the nuts are tightened down to compress the packing-ring. When compressed, the packing-ring will be forced well down into the V-shaped space below it between the expanded end of the soil pipe and the outer surface of the downwardly and outwardly iiaring projection of the cap.
Having thus described my invention, what I claim is- A closure for soil-pipes, comprising a Hoorplate having a central aperture through which the soil-pipe projects and an outlying beveled iiange, against whose edge it is adapted to be expanded, `a sealing cap-plate having a groove in its under surface, an elastic packing-ring lying in said groove, a downwardly and outwardly flaring conical projection from the capplate, and screws and nuts for completing the joint; substantially as described.
In testimony whereof I ailix my signature in presence of two witnesses.
WILLIAM E. DELEHANTY.

WV. Sen'r'runeoon, D. R. TABER.
