METAL PIPE QONNECTlON.
SPECIFICATION forming part of Letters Patent No. 514,768, dated February 13, 1894. Application filed May 13, 1893. Serial No. 474.138. (No model.)
To all whom it may concer-n:
Be it known that I, PATRICK J. MCGUIRE, of New York city, in the county and State of New York, have invented a new and useful Improved Metal Pipe Connection, of which the following is a full, clear, and exact description. a
This invention relates to an improved device for the attachment together of metal pipe sections, andparticularly for the j ointed connection of pieces of cast iron pipe used to convey away the exhalations from watercloset attachments to sewers, technically known as soil pipes.
As ordinarily constructed, soil pipe sections arejoined together byenlarging one end of a pipe section, and slipping the small end of a similar section into this hub end, leaving an annular space between the pipes, which is partly filled with oakum that is calked upon the bottom of the annular recess,to prevent an escape through the crack between the pipes at the bottom of the recess, of melted lead, that is poured into said recess upon the oakum, and when cool is calked to expand it, and produce a tight joint between the pipe sections, and also firmly unite the two pieces of pipe.
It has been found by testing the joints of soil pipe connected in the manner just ex-- plained, with water introduced under pressure, that more or less leakage occurs after the soil pipe has been in service forsome time, and the oakum rots, so asto leave 7 the lead joints without a base, and the settling of the soil pipe produces strains upon the lead joints, the result being that sewer gas filters through the joints between the soil pipe sections, and pervades the building in which said pipe is erected.
The objects of this invention are, to provide a novel, simple, and reliable pipe connection, that is especially well adapted to join together the sections of a soil pipe, and preclude the passage of sewer gas through the joints between said pipe sections; a further object being to materially expedite the work of erecting a soil pipe in a building, thereby cheapening the cost of construction, and also to provide a pipe joint that can be reliably produced by unskilled labor, at a less cost than is required where skilled artisans are employed to join soil pipe in the ordinary manner.
To these ends, my invention consists in the construction and combination of parts, as is hereinafter described and claimed.
Reference is to be had to the accompanying drawings forming a part of this specification,
in which similar letters of reference indicate corresponding parts in both of the figures.
Figure 1 is a longitudinal sectional view of two soil pipe portions, showing the improved joint connection between them; and Fig. 2 is a longitudinal sectional view of two soil pipes in part, joined together by a modified form of the improvement.
In the drawings, A represents the .end portion of a soil pipe'section whereon a diametrical enlargement is produced for the reception of the straight cylindrical end portion B, of another soil pipe section, the internal diameter of which is similar to the caliber of the pipe A, where not enlarged. The hub enlargement A, of the pipe A,is comically formed from the point a, where iteoommences to flare, and at a proper distance from a, the hub A is rendered cylindrical, thus alfording an annular channel of a suitable diameter,whic'h extends from b, to the terminal of the hub, where-v on a bead c, of the usual form is externally produced, which bead serves to strengthen the hub at its edge. The conical portion of the hub A, is designed to receive a base ring C, that is preferably formed of the same metal as the pipe A, and is conically shaped on the exterior, to adapt it to fit accurately upon the inner surface of the hub portion it is seated upon, and when said base ring is introduced, its internal diameter should correspond with that of the pipe section A, forming a continuation of the same. The cylindrical part of the hub A, is interiorly threaded from the edge toward the conical portion thereof, as at e, and the cylindrical end portion of the pipe section B, is externally threaded at a point it, that will locate said thread opposite the thread e, when the pipe sections are connected.
To produce a hermetically sealed joint between the pipe sections A, B, so that they will practically become one pipe, the base ring C is coated externally with any suitable liquid to form water and gas tight joints between metal surfaces, and then the ring is bedded within and upon the coniform portion of the hub A. The pipe B, is now inserted and its end is caused to impinge upon the ring 0, the wall of said pipe being maintained concentric with the cylindrical part of the hub it is located within. Melted lead is now poured into the annular space between the pipes A, B, that are supported in a vertical position to facilitate the introduction of the lead. With a proper tool the lead joint D, is expanded by blows applied to the tool, so as to drive the leaden ring closely within the threads 6 and 72, and also consolidate the soft metal of the ring D, upon the base ring 0, which will complete the connection of the pipe sections A, B. It will be seen that the calking of the leaden filling ring D, will so solidify said ring, that settling of the soil pipe will not be liable to disturb the integrity of any of its joints, and the permeation of liquids or gas through said joints will be precluded in an obvious manner.
It is sometimes necessary to join a short piece of pipe, such as B, in Fig. 2, with the pipe section A, having the improved hub end. In such a case, it may be advisable, if said piece B is devoid of the thread 71, to form a circular flange G on the base ring C, the interior diameter of which flange is so proportioned,that a small quantity of oakum i, may be calked down upon the base ring 0, as represented in Fig. 2, filling the space between the flange and the end portion of the pipe portion B; then the melted lead to form the ring D, is poured within the larger annular recess covering the flange C and oakum i to a proper depth, and seating said joint ring upon the top surface of the base ring that is outside of the flange C. The consolidation of the leaden joint ring D, being produced by calking it as before explained, will laterally expand the soft metal and force it to penetrate to the bottom of the thread 6, so as to form a perfectly gas tight joint, the pressure produced upon the base ring holding its cemented surface forcibly impinged upon the conical inner wall of the hub A, which coacts to prevent any escape of sewer gas through the joint formed, as shown in Figs. 1 and 2 of the drawings.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a pipe joint, aconically enlarged hub, a mating joint ring seated therein, and a soft metal joint ring formed between a cylindrical extension of the conical hub portion and external threads on an inserted pipe section, substantially as described.
2. In a soilpipe joint, the combination, with a pipe section having a hub end that is partly coniform and partly inserted cylindrical, and a cylindrical pipe section, of a base ring that is coniform and fits within upon the coniform part of the hub end and receives the end of the inserted pipe section, and a soft metal joint ring seated upon the base ring, substantially as described.
3. In a soil pipe joint, the combination, with a pipe section, a hub thereon partly conit'orm and partly cylindrical, and threaded within said cylindrical portion, of a soil pipe section externally threaded, a coniform base ring seated within the hub on its coniform portion and impinged by the end of the threaded pipe, and a soft metal joint ring between the threaded parts of the inserted pipe and the cylindrical end of the hub bearing on the base ring and expanded in the threads of the pipe and hub, substantially as described.
