MANiIoLE.

.Application led Novemb'er 24;, 1926. Serial No. 150,442.

My invention relates to manholes, of the type used to permit access to sewers, drains, conduits, and the like.

It has been theV practice heretofore to construct the manholes commonly used in city streets, and other locations, to permit access to drains, or water, gas, or electric mains, by first excavating a hole of suitable size, and form, and then building a foundation of concrete,'on which is erected a wall of bricks and mortar. After the brick work is completed, it is customarily Waterproofed by a coating of tar, or other suitable material.

A cast iron section for supporting the manhole cover Hush with the' surface of the street or sidewalk, is then set in place.

The ordinary construction above described is open to the serious disadvantages that only highly skilled masons can be used, and much time is lost in waiting for the cement foundation, and the motar in the walls, to harden. A further disadvantage is that the great weight of the structure necessitates a substantial and costly foundation. Where the earth is soft, or quick sand is encountered,

piling must be employed to support the.

foundation. I'

Among the objects of the present invention are to provide a sectional manhole construction Which can be quickly installed without the use of skilled labor; which can be economically manufactured and transported; which will be sufficiently light in weight kto permit an inexpensive foundation t0 be employed for its support; which will rovide a simple means for accurately aligning the top of the manhole with the slope of the surface of the place of embedment; and which will provide means for raising or lowering the top of the manhole without the necessity of destroyingl the surrounding pavement.

The improvement claimed is hereinafter fully set forth.

In the accompanying drawing: Figure 1 is a vertical central section through a inanhole embodying my invention, the pavement and surrounding earth being also indicated in section; Fig. 2, a similar section through the top portion of a manhole embodying a horizontally tapered section used to bring the top of the manhole in alignment with the crown slope of a road; Fig. 3, a central vertical section, through the top portion of a manhole, illustrating my improved means for raising and lowering the top of the manhole; Figs. 4 and 5, similar'sections, illusti'ating structural modifications; Fi 6 a vertical central section of a manhoa, bodying two horizontally tapered sections, disposed so as to give the upper rim of the top. section the maximum incline; Fig. 7, a view, similar to Fig. 6, the tapered sections being disposed t0 position the upper rim of the top section horizontal; Fig. 8, an isometric .view'of one of the tapered sections shown in Fig. 6; Fig. 9, a central vertical section of a manhole, embodying two telescoping sections, and two unflangedv horizontally tapered spacing sections, interposed therebetween, the spacing sections being disposed so as to give the upper rim of the top section the maximum incline; Fig. 10, a view, similar to Fig. 9, the spacing sections being disposed to position the upper rim of the top section horizontal; and, Fig. 11, an isometric View of one of the tapered spacing rings.

In the practice of my invention, referring descriptively to the 'specific embodiment thereof which is herein exemplified, the manhole is shown embedded in the earth, with its riin flush with the surface of the road, 10. The in anhole embodies a foundation plate,` 11, which supports ai plurality of superposed sections,^l3, 14, l5, 16, 17, 18 and 19. Each of the sections here shown is in the form of a cylindrical wall, but they may be of any other cross section, and the tops of said sections are each formed with a peripheral olfset, or lip, to provide a horizontal supporting surface, 20, for the bottom of a superpOSed section, and a vertical flange, 21, adapted to prevent transverse displacement of the sections, and to provide a space for a seal of tai', or the like, whereby a leak-proof joiiitui'e may be effected between abutting sections.

rlhe lowerinost section, 19, i'ests directly on the foundation plate, 11.

To provide for the admission of pipes or' leads into the manhole, thewall of one of the sections, in this case section, 19, is formed with an opening communicating with an outwardly directed tubular extension, 23.

Sonie of the sections, in this case the sections 18 and 19, are made of greater diameter than the other sections, to provide ample interior space.

The sections, 17 and 16, are tapered, or

substantially frusto-conical in form, to provide for va reduction in the diameteriiof44 the manhole, at its top.

The sections, 15, 14 and 13, are similar 1n diameter, which diameter is Yless than that of the other sections, and they are of dlfferent depth, respectively. i

The peripheral offset at the top of section, 13, is adapted to receive and retain a suitable cover plate, 24.

Referring to Fig. 2, the top sectiop, 13, 1s horizontally tapered, to provide for aligning its cover -with the slopinor surfrice ot' a crowned roadway. It is to e understood that any of the sections may be horizontally tapered to effect the desired slope for the cover of the manhole.

InV practice, it sometimes happens that l the manhole, or the pavement, sinks, and' it is particularly desirable that means be pro-A vided to enable the top of the manhole to be raised or lowered without the necesslty of destroying the surrounding pavement. To

this end, I have provided the constructions illustrated in Figs. 3, 4; and 5. Referring Fig. 3, a straight cylindrical section, 25, 1s shown as superposedon section, 16. T elescopically fitted within the section, 25, 1s a section, 26, the top of which forms a seat, 2T, for the cover, 24, and an outwardly d1- rected horizontal fiange, 28. Spacing secing the depth of the spa-cing members, the

' top of the section, 25,*and the flange, 28. It

will be obvious that by adding, or taking out, a spacing member, or members, or varying the depth of the spacing members, the top of the manhole may be raised or lowered, to bring it Hush with the surface of the place of embedment.

Fig. 4 illustrates a structural modification, in which one of the bearing faces of section, 25, is inclined to the axis of the section, to effect the desired slope for the cover of the manhole.

As shown in Fig. 5, the section, 25, rests on a supporting ring, 33, which, in turn, rests directly on any suitable base.

In the construction shown in Figs. 6 and 7 the top section, 34, and the intermediate section, 35, are each made in the form of a cylindrical band, and each.is provided with a bearing surface, or seat, 36, extending substantially around the band, and disposed substantially throughout in a plane inclined to the axis ofthe band. It will be obvious that by disposing the sections so that `the lowest portions of the inclined bearing per rim of the top, section will be positioned substantially horizontal, as'shown in Fig. 7. Obviously, any suitable incline may be given to the rim of the top section, by relatlvely rotating the sections.

I n Figs 9 and 10, the cover section, yBZpis shown with a depending flange, 38, which telescopes into the lower section, 39. AInterposed between the two sections are three spacing sections, two of which, 40 and 41,

respectively, are each horizontally tapered to provide a bearing face, 42, inclined to the axis of the section. By rotating the spacing sections, the upper rim o the cover section may be adjusted from the horizontal position shown in Fig. 10, to the extreme inclined position shown in Fig. 9.

Preferably, each of the sectionsis made of cast iron, which material enables a construction of great strength, in proportion to its weight, to be produced, at a relatively low cost. It is within the contemplationl of the invention, however, to form the sections of any Aother suitable material. So far as I am aware, it is broadly novel to employ a horizontally tapered section to impart to the cover of the manhole a slope in accordance with the slope of the place of embedment. It is also broadly novel to provide means permitting the top of the manhole to be raised or lowered, without the necessity for destroying the surrounding pavement.

I claim as my invention and desire -to se- Vcure by Letters Patent:
