SEWER "cons'rnucrron.

Specification of Letters Patent.

Application filed July 24, 1908. Serial No. 445,251.

more sanitary than the ordinary cement sewers now extensively used and at the same time less expensive and capable of easier and more rapid installation, the completed sewer being practically continuous or unbroken from end to end, or in other words, without any open joints therein.

With the above and other objects in View, the nature of which will more fully appear the description proceeds, the invention consists in the novel construction, combination and arrangement of parts as herein fully described, illustrated and claimed.

In the accompanying drawings :Figure 1 is a vertical cross section through a sewer embodying the present invention. Fig. 2 is a vertical longitudinalsection through the same showing the manner of uniting adjoinone of the sewer sections. Fig. 4 is a detail vertical cross section showing the means for causing the sewer sections to drain off water during installation. Fig. 5 is a vertical cross section showing a modified form of section.

The construction of the sections of the,

sewer is best illustrated in Fig, 3 in which one of the sections is shown in detail wherein it is seen to comprise a cylindrical body 1 and a base 2, the base forming a reinforcement for the body 1 and in the preferred embodiment of the invention comprising a fiat supporting bottom 3. Atthe opposite sides the base extends partially upward along the sides of the body and is. made sufliciently thicker than the body to, provide oppositely located shoulders or ledges which extend lengthwise of the section and provide a support for a body of concrete indicated at 5.

any usual composition such as Portland cement, sand and gravel or crushed stone, while the body 1 and base 2 of the sewer sections are preferably composed of vitrified clay, which is salt glazed so as not to admit ing sections. Fig. 3 is a perspective view of The concrete body 5-may be composed of of the lodging or adherence thereto of sediment. It will also be observed by reference to Figs. 2 and 3 that the base 2 is extended at one end beyond the corresponding end of the body 1 to. form a stay or socket 6 to receive the adjacent end of the adjoining section, the body of which projects beyond the base as shown at 7. In this way the sec tions of the sewer overlap each other or more accurately speaking, the body portion of one section overlaps the base portion of the adjoining sections thus attaining an accurate alinement of all of the sections. The outer coating 5 is applied to the sections after the same have been placed in the ditch and combined in the manner above described, an outer incasing, shell or jacket of any suitable material being employed in connection with the sewer sections to enable the concrete while in a plastic condition to be introduced between the body 1 and said outer shell or jacket, it being understood that when the concrete has hardened sufiiciently, the-said outer shell or jacket is removed. As said outer shell or'jacket forms no part of the present invention, the same has not been shown.

It is also within the scope of this inventionto make the base 2 of .suflicient depth and other dimensions to provide for the formation therein of one or more drain channels 8 in the installation of the sewer and carrying offof the water in the bottom of the drainage while the construction is in progress.

By means of the construction described, a

,sanitarysewer is produced as by reason of the interior of the sections being salt glazed or of vitrified clay there is little liability of cement or other refuse lodging in or adhering to the inner surface thereof. The c011- struction described also greatly facilitates the building of the sewer as a whole as the sections form cores or formers around which the concrete is laid and when the sewer is complete, it is practically continuous or without joints from one end of the line to the other. Furthermore, the weight of the sewer sections is approximately only about one-half the weight of the sewer pipe section now in common use which admits of the same being" manufactured more economically and handled with greater ease at all points.

By reason of the outer layer or coating of cement extending from shoulder to shoulder.

Patented Aug. 31, 1909.

' dium for the vitrified clay sections, holding and continuously across the joints between the adjoining sections, such layer or coating acts as a reinforcing and strengthening methe same in perfect alinement. The base or invert may be made separate from the remainder of the sections Where conditions demand it for convenience in handling, the

the tubular body eing then placed upon the" base or invert in readiness for the 'concrete coating or reinforcement;

1. As'ew'er pipe section comprising a ho'lE low cylindrical body and a base integral therewith, the inner wall of the base being coincident With the inner Wall of the body and the base being of greater thickness than base or invert beingj placed in the ditch and the body at the junction of the body and "base to provideoffset longitudinally extending shoulders.

2. A sewer pipe section comprising a tubnlar' body, and a relatively thick base integral with the body forming oifset longitudinal shoulders opposite the juncture of the body and base, said shoulders projecting outward beyond the plane of the body, the base being extended at one end beyond the body to form a seat or socket for an ad-* joining section, and the body being extended at the other end beyond the base for a like purpose.

In testimony whereof I aflix my signature in presence of two Witnesses.
