CONDUIT.

Specification of Letters l'atent. v

Application led August 16, 1909. Serial No. 513,18Q.'

To all 'whom it may concern l Be it known that T, \\'ii.i.i.\.\r (i. Fanno, a citizen of the linited States, residing at Jackson, in the county of Jackson and State 5 of Michigan, havqinvented certain new and useful Iniprovei'nents in Conduits,of which the following is a specification.

This invention relates to conduits. One'object is to provide a sectional rein- 40 forced concrete conduit which will be tightI under auch pressureas'attained in water supf ply lines or in carrying gases or other flzfids under coiisideral'ile pressure.

Aiiotherol'ijeftof the invention' is to pro vide a reinforced concrete conduit including' a cylinder embedded therein with. the

cylinder' and other reinforcements protected against deteriorating agencies veither from within the conduit. A

Another object. 'of the invention residesyin A the provision of a reinforced concrete conduit composed preferably of sections, each section including a thin cylinder embedded the atmosphere without or fromlthe fluids 'in the concrete with the abutting ends of the cylinders jointed by .sealing strips or bars which are compressed by suitable tools over 40 inders being so disposed with relation to one another that they may be jointed together throughthc instrumentality ot' suitablefsealing strips which will permit of a -sinall longitudinal movement or stretching 'ntthc conduit sections after completing; the joints Yto provide an. expansion joint and also to permit of longitudinal adjustment in bringing the flanges together when appll.- ing the'sealing strips.

lt; is still further designed to provide a sectional. reinforced concrete 1conduit em` hndying-an inner and an outer jacket inierposed between which .isidisposed a metallic cylinder having inwardly and outwardly 5 directed aiiges at its ends, the cylinder and its ends being not. exposed to deteriorating agencies either frein the atmosphere witl1- out o i' from the fluids Within the conduit.

'ith the above andotheiobjects in View,

.the present inventionconsists inthe coinbiiiaton andl arrangement of. parts herein- .after more fully described, illustrated in the accompanying drawings, and particu-. lai-ly pointed out in the appended claims, it being understood that changesl may beinade in theV form, proportion, size and minor details without departingr fromtliespirit or sacrificing any of the advantages ot the invention.

In th drawingsz-V-Figure l is a longitudinal sectional view `of two abutting sections ofthe conduit assembled -in accordance with my invention. Fig. 2 is an" endview of one cof tne sections.` Fig. Buis a detailedv perspectiie view of one end of one of the cylinders yillustrating the flanged ends.: Fig. 4 iba detailed viewillustratlng the position of one of thesealing strips with :relation to abutting ends of metallic sections prior to compressin the sealing strip over the abutratenteaiaar. 2.6, 1912..

ting ends o the cylinders.V Fig '5 is asimilar view illustrating the sealing strip comp pressed'or` .otherwise applied permanently to the abutting ends of the cylinders.

Referring now more particularly to the accompanying drawings, the reference characters l and 2 indicate abutting concretel lsections, each section -having 'a thin4 metal cylinder 34 embedded therein, itlie cylinders` being slitted or hi-sected at each end 'to permit of the formation of; the inwardly directed fianges '14 and the outwardly directed flanges 22,'as` and fon'the purpose hereinafter understood.

That. portion a'o the concrete upon the outer side of the metallic cylinders 3 con` stitutes an outer jacket and that portion 7;

.of the concrete withiii'thecylirders provides a liningso that the cylinders are protected from the` deteriorating agencies either from 'the atmosphereiijithout org-from' the iuids within the cf'indiiit.l 'llee, conduit ismade tight by .the`v metallic. cylindersembedded therein, tlie cylinders n otheilig intended to resist the pressure or the contained fluids, which pressures areislistainedV by Athe Areinforcing 5-ontsiderfxit-th',thin metal cylinders. The liniiig-poi-.timilb within the cylinders may be reinfrii'etljpto. prevent cracks and to hold it in place. Any type of' reinforcement may be employed, and by Virtue of the cylinders being embedded in the cona crete, inthe manner stated, they are profinside. y i

The'coiicrete section l Is 'provided with a tected by a smooth concrete lining on the semi-annular shoulderi at one end for col operation with the semi-annular shoulder -7 of the concrete section 2 to provide 'anex' ternal semi-annular recess adapted to be lilled with mortar or other sealing material 9 tofcalk the. abuttingends' of the sections 'at their' lower portions. The section 1 is also provided with a semi-annular inclined meeting face 10 disposedA .in advance 'of the shoulder 6 for dispositionopposite'to the semi-.annular inclined meeting face 11 of the section 2, and if these meetingfaces 10 and 11 are nottted tightly together the sealing material 9 may pass into the space between them to seal said meeting faces.

The section- 1`has its lining portion b terminate short Iof the shoulder 6, as at 13,

for coperation with the inclined portion 12 of the lining b of'section 2 to4 rovide an internal recess c for the reception of the lower inwardly directed semi-annular flanges 14 of the metallic cylinders. Thus, they recess c formed by the inclined portions, 13-12 of the linings b of the sections 1 and 2 'is semi-annular. Said recess is preferably SUdovetailed, as shown, in any event. beingv wide enough to over the lower contiguous flanges 14 of ad'- jacent Imetal cylinders after theconduit sections are laid.l asjclearly shown vin"Figs.1 and 5. The pinching together ofthis seal ing strip l5' could be done in sections," that is, the jaws of thepresslnot, showjii)would close on four to sixfinches at "a time 'and proceed around the'semi-annular joint.

After the flanges 14 are secured together the annular recess c is filled with mortar or other suitable material 8 to cover the fianges 14 and strips 15 or other securing means and to provide a smooth interior for the 'conum 'lhe recess c is bounded at the center of the conduit by the shoulders 17 at the lower ends of the seini-annularprojecting portion 18 of the section l which shoulders 17 are adapted to rest upon, the shoulders 19 of the section 2', there being a second internal semiannular recess f between the abutting ends of 'the cylinders which will be calked or sealed as are the other -recesses by the sealing material g.

The outer jacket portion a of the section 1 terminates short of the end of the latter' throughout substantiallyone-lialf of the cirl and is inclined, .as at 20,V forxcoperation with a similarly inclined portion 21 of the section 2, to provide a semi-annular external recess d to receive the upper outwardly directed flanges 22 of the abutting cylinders, as clearly shown in Fig. 1. The edges of the fiangesA 22 are` shouldered-,rasata 23, to provide an effectual connection between the flanges and, the sealing strip 24, which is preferably ofthe same material as the sealing strip 15 and which is preferably applied to the flanges 22 inthe saine way as set forth in connection with the sealing strip v15 with relation to the inwardly turned flanges 14 ings, respectively, to the'metallicfcylinders,

as clearly shown in Fig. 1.

Each end of each concrete 'section may be` formed the saine or eachsection may have one cnd.-formed as .shown 4and its'opposite end the reverse, that is, the `section'l may l vhave one 'end formedexactly'as shown with its opposite end formed like theend shown .of section The reinforcing material. of

lthe concretesection's may be tied together,

if desired, at. the abutting ends of t e sec-- tions. In any event, the construction of the flange jointsherein described permits of a smalllongitudinal movement or' stretching of thepipe sections after" completing thev K joints, the construction also permitting of a longitudinalc adjustment in bringing4 theA` flanges together when applying the sealing strips or in otherwise securing -adjacent flanges together. i

From the foregoing it will `be understood that the top poi-tion or upper half of the metallicl cylinders may be secured' together outside of the conduit while the libttom portion or lower half of the metallic cylinders may be connected together within the conduit. At the points where the flanges change in direction from inside'tooutsde, that is, atf'the points '.fr, the cylinders at these points of abutment may be fused, brazed, soldered, welded, riveted 0r calked. If referred, the. sealing strips may be ex@ ten ed 4over the ends of -fthe respective fianges 14 and 22,.as indicated at 14' and,

using the same soft metal fof to seal the joint from either or 4both 'sides.

It will be apparent that Ip,pryide l1aim water-tight conduit. in that if water should;
