` SEWER-PIPEL- tain new and useiul Improvements in SewerfPipes', oi

- 'which the following is arspe-cieatiou.

This invention relates to improements in pipes oi that type which are commonly employed for the con- A i @struction of sewers and 'which areiormed insections connectedby spigot jointes, The pipe embodied in 'the present invention is digned iw'be formed oi some plastic material such as concrete having a .number oi peculiarly designed reinforcing members embedded therein. l'he reinforcing members'are peculiarly iormed so as to prevent any serious injury to j the pipe by a slight cracking ofthe concreteand also so asto enable the concrete to be thoroughly taxnped the formation ot' the pipe.

The numeral 1 designates vthe Apipe which is enlargedat one'end to yiorzn thebell 2 andv which is i shownas having a circular cross section, although i other cross sections could be. employed without dei parting from the spirit oi the invention. This pipe- `which is formed oi some plastic triat'erah Preferably concrete,'is reinforced by ymeans o the ti l3 embed. ded in the concrete. ties areangular and are approximatelyy ll-shaped and comprise a cross b ar y4 which isla'terally disposed inthe concrete so as turesist any tendency of the pipe to burst or split longii tndinally. t each end or' the mss bars 4 there is an arm 5 and these arms 5 extend longitudinally along thepipe so as to resist any tendency oi the concrete to bre-.tk transversely.

` y One of the most seriousob'ections that have-been brought forward against the use oi reinforced concrete hitherto has been that the concrete almost invariably cracks with age and that the Cracks have a tendency patented' .my 1o, iso?.

seen .that in the construction oi a reinforced concrete pi pe,` it would'be veryv objectionable to employ either` transverse rings extending'continuonsly around the pipe or continuous longitudinalmembers, jsince when thecracks once'started, they would follow the continuous mekmbern'andy very *quickly produce a rnpture. lniorderto overcome this dil'liculty; theA U- shaped reinforcing ties 3 are'amtnged in succesive transverse series of rings around the pipe, the crossv `bars inr each `ring being in staggered relation to the and obtain asecure bond between the concrete and the reinforcing members. Inv constructingthe pres- `ent'pipe.' itis preferably formed in a. series of succensite layers which are each thoroughly taznp'edt.

The preferred method of procedure is to placevenough concrete in the mold to form one layer which mayl be Y designatedin the drawings by the numeral 6.v The U-shaped ties are then placed in position andthe layer oi concrete thoroughly tamped. Thenext layer T of concrete may then be placed in the mold upon the `first layerand the process again repeated, the ties `3 in the second layer being so placed that the crues' bars 4 alternate and oyerlap the cross bats 4 in the layer Band'that the arms 5 the layer 7 extend longitudinally/along the pipe so as to overlap and loosely engage the cross bars 4 ot' the ties in .the layer 6. The pipe is thus formed by a series oi successive layers each of rt'hichiis thoroughly tamped'so as toelixninate the voids `and force the Vconcrete into a closeuniun ,wv-ithth'e'tie's-fvv L, Where thcpipe 'B formedvtvith afbell 2, the same preferably basa continuous lring or kband 8 embedded therein, which 'is overlapped by a series oflongitndi.' 1700 nal reinforcing rods v9 extending into they body of the These ,longitudinal rods 9 comprisev twouarms pipe. v i l0, one of the arms connected by an offset portion ,being embedded in the bell, nhile theopposte arm l is embedded'in the body oi the pipe and overlaps 105 and loosely engages the U-shaped reinforcingl ties 3. rIt will thusb'e seen, that the bell 2 is securelycorp nected tothe' body of. the pipe and that it is reinforcedA by thfering 8 against the lateral pressure ex crted by the spigot 1l oi the adjacent pipe when the 11.0
