Street tral'lic becai'iee oi the excavation necessary to jnrovide ior the builiiling' of the manhole.

The main object of the present invention into provide a manhole constructed in sections whi zh can be manufactured by cheap labor away from the site of the proposed manhole and which can be 'very quickly as-v sembled by cheap labor in the manhole excavation.

Another object of the invention resides in forming the manhole sections so that they can be integrally united at their joints, and thereby produce a manhole integral from top to bottom when located in sites.`

llinother object oi" the invention is to provide each section with one or more rungs which lorm a ladder for the manhole when the sections are assembled.

Other objects off the invention will appear as the detailed fflescription thereof proceeds.

Figure 1l. is a vertical section through one oi' the umts taken on line 11H11 of Figure l0.

In the iorm f-:honi'nin Figures lj 2 and 3 oil' the drawing7 the manhole is of the truncated cone tyjgie, and compu-ieee bottom section l Seated onv a flatbed of concrete 2 and having' apertureeI 3 and Il through the sides thereof to receive the ende oilE pipee4 5 and o.

The bottom section is preferably cylindrical, while the euperposed sections 7 and il are shaped. as hollow truncated cones. The section l comprises an inner cylindrical plate 9 concentrically arranged within and spaced apart trom an outer cylindrical plate l0, the space between the platee 9 and l() heing filled with pitch or concrete or any other suitable binding material, 11.

The upper end oli the plate E) le slightly oli'eet inwardly to :form an ollieet bearing` l2, and the upper end of plate 10 ie oil'eet outwardly to liorm oil'eet bearingl 13 cooperating;` with bearing.;l l2 to form a seat for the corre- :spending ond lei: of the section 7.

Parte of the offset bearings l2 and 13 are further oli'set to 'orm pour epouts l5 through which the binder ll is adapted to be poured when the sections are assembled.

'lhe joint between the sections 7 and 8 is substantially the same as the joint between sections l and 7 and the parte thereof are similarly m'unbercd. The pour epoute l5 in ihc joint between ecrtione4 l and 'i' lie in the plane of Section and make the joint appear slightly dill'erent trom the joint between eee tions 7 and 8, "where the pour holes are shown at an angle of 9() degrees relativo to those Shown in the lower joint. j

` It munt be uaderstoml that the elemente ot the Several sections; are assembled away from the manhole excavation and that the binder lll, in poured into the space between er' and outer plates olf' each ocation ill uch el ce troni the bottoni of the section up to thefoifsets formed to receive ,the lower end of the next superposed .-section. then an upper section located binder 11.

properly on the one immediately below'vit,

binder material can be poured in through pour holesV 15 to till the joint and integrally unite thetwo sections.

The sections 7 and 8,. shaped as hollow truncated cnes,arealso made of inner and Vouter plates 16 and 17 with the inner plate .16 arrangedc'oncentrically within the plate y 17 andgspaced apart therefrom to receive the binder 11.Vlr

Theiupper section 8 is finished flush at its top-edgeto'receive a man-,hole cover 18 which may, 1f'desired,`be formed oit Ytwo plates 19 and 20, separated by binder 11. As shown vin the drawing, the cover 18` is provided with a flange 19 adapted to seat in a recess 21-formed in a concrete or other suitable ring, 'and maybe removed by hooks adapted to pass through holes 22 and 23 formed in the top plate oi cover 18.

f The conduits and 6 are also preferably formedby cylindrical tubes 24 and 25 conc'entrieallyV arranged and bound together by .The inner tube 24 has a fla-nge 26 turned out to engage the inner plate 9 et the section land the outer tube has a flange27 formed to engage the outer plate '10 oti section 1.

`The whole construction intended to provide-'completeinsulation between the inner and outer plates of the manhole and between the inner and outer tubes of conduits connected thereto. .The plates-are intended to be made of rust proof iron and to be assembled in sections with binder between them beforetheir assembly in the manhole excavation. V

In order to obviate the necessity ot using ladders in kthese manholes each section is provided with a rung 28 formed by a rod of steel or other suitable material inserted asa chord vinslots cut in the offset 12 of the inner plate of each section.

In the modification shown in Figures 4, 5,

i and 6, the sections are all cylindrical, the

lower-section 29 being formed of concentrically spaced apartfplates, 32 and'33 vseparated by the binder 11..

Conduite 34 and 85 snnilar tothe conduits 5 and'G are similarly connected to the inner and outer plates 32 and 33, respectively.

' In-order to form the joint between the scct'ions29 and 30,-the outer plate is inn wardly offset at its upper end to form a recessed portion 3G and a shoulder 37 formlower section 29. The inner plate 39 of section 3() tits snugly against the outer face of theinner plate 32 of the lower section 2!) and at intervals is provided with slots 14.() adapted to permit binder to tlow between the upper and lower sections in the joint thereof when such binder is poured through the pouring olt'sets 41 suitably formed Varound the inner plate 32.

,The upper section 31 is connected to the adjacent lower section 30 by a similar joint and terminates at its upper end to form a seat for a concrete ring 42 in which a manhole cover 13 similar to that shown in Figure 1 is adapted to seat. Each of the. sections in this modification is provided with a rung l1-il extending across the inner plates as a chord and seated in slots t5 and 4G formed in the upper edge of said inner plates, the inner plates otl the upper section being slotted to seat over the projecting ends of said rungs and lock them in position.

The modification shown in Figures 7 and 8 is also cylindrical and the joints between the sections L17, A18, 49 and 50 are the same as are shown in Figure 1. In this moditication, the lower sections L1-7 and 48 are provided with apertures formed to receive tubular conduits 51, 52, and 51, and the inner plates of all the sections are slotted to receive the rungs to form a ladder as in the previously described modifications. The manhole cover 56 is similar to that shown in Figure 1 and adapted to be similarly positioned in a concrete ring 57 seated on the top of the upper section 50.

In the forms shown in Figures 9, 10 and 11, the sections are rectanguliirly shaped to form when suitably united a large vault or chamber from which conduits may extend in any desired direction. These sections are each composed ot separate units adapted to be bolted or riveted together. For example, t-he section 58 shown in Figure 1() comprised of end units 5t) and G() connected by flanges G1 and (S2 to a central unit (33. Stiffening plates (it (see Figure 11) are bolted or riveted to said flanges 61 and (32 near the top and bottom of said unit in order to form struts to resist the inward pressure on the walls ofthe section.

Conduits 65 and (itlextend from the end units 58 and Gt), respectively, and are coinposed of inner and outer tubes (3T and ('8 adapted to be connected to the inner and outer walls (S9 and 70 of each unit, binder ll being poured into the spaces between spaced apart walls of said conduits and sections, as in the other mmliiieations.

The various sections in this rectangular form of the invention are adapted to be superposed one on the other and connetded by joints similar to those shown in Figure 1 of the drawing, which joints are adapted to be filled through pour holes 71 suitably llo formed around the outer and inner plates of the lower section. Each of the sections and the units thereof may be provided with ladder rangs 72 either riveted or otherwise secured to the opposite walls of each unit or set into slots formed in t-he upper-edges of the inner plate of each unit;

A single cover 73 may be extended over the top unit and provided with flanges adapted to facilitate the seating thereof on the top section. lVhere a large cover used suitable manhole plates 74: 'may be formed therein in order to 2give admission to any part ol the manhole wall without necessitating the raising of the whole cover 73. The several parts of the cover may beY formed' by spaced apart plates and the spaces between said plates may be filled with insulartingi binder ll as desired.

lt will be apparent from the foregoing description that I have provided manholes and vaults which may be varied as to size and which may be formed in sections ot standard sizes adapted to be assembled very quickly and cheaply in previously formed excavations. It will also beapparentthat conduits may be connected up'very quickly to any of the sections forming` part of the i'nanholcs described herein.

Vihile l have shown a conduit as entending from intermediate parts of each section, it is to be 'understood vthat these conduits may be readily located at the joint between superposed sections, which may be notched to lit into each other and over any conduit positioned therebetween with the insulating,l binder properly packed between the element of the sections and the conduit.

What I claim is:
