. .Anothenimportant :feature. of our {inventionis the meansifonsupporting pipes .o'rtheJike within the conduit.

Each .foot.22 has. depending; lugs, 25 to abuttingly engage the upper portions of the side ,walls or, the upper. edges of :the Ndrain channel,2 in the base .-A. Each upstanding -arm .21 has .longitudi nal channels 26. to, face the. channels in the op-.
posite standard, nd-shaft;supporting. braclgets 27 are slidably mounted in said channels. Each bracket. 27 has at one end a seat 28 to receive one end of a shaft 29, and at the other end has a leg 30 which rests in a seat 31 formed by bosses 32 projecting upwardly from the foot 22 in spaced relation to the bases of' the channels 26. The brackets 27 can be easily slid into and out of the channels 26 and the elevation of the seats 28 may be varied by cutting on: portions of the legs 30so that the brackets can be made of standard size and later out according to specifications of the particular conduit. Each shaft 22 has a roller 33 rotatably mounted thereon to support a pipe or the like E.
In constructing a conduit in accordance with our invention the base A is first poured in the bottom of the ditch in which the conduit is to be laid, the drain channel being molded into the top of the base. After the concrete has hardened the pipe supports are set upon the top 1 of the base in the desired spaced relation. The feet 22' are simply set upon the top of the base with the lugs overhanging the edges of the drain channel'and in abutting relation to the sides thereof In this way the standards are easily and quickly alined with each other along the edges of the drain channel. The brackets 2'7 are then adjusted to the proper elevations, after which the shafts 29 are mounted in the brackets and the pipes E may there be laid on the rollers 33. The side walltiles 3 are then set by joints 35 on the top 1 of the base at opposite sides of the drain channel 2 in end to end relation to each other with the horizontal openings 4 in alinement longitudinally of the conduit. Ifv
necessary, the standards 23 of the pipe supports maybe adjusted to locate them between the ends of adjacent side tile 3, and the webs 24 of the standards are embedded in the joints 36 between the side'tile; and, of course, the side tile are preferably set in contacting relation with the standards 23.
Then the top tiles 6 are set upon the tops of the side tile 3 with the mortar joints 60 between the edges of the top sections 6, and the joints 12 between the ends of the top sections.
With this construction; it will be observed that the various sections of the conduit may be separately and independently erected or installed, and that the pipe supports and pipes may be set and laid directly on the fiat top of the base without any interference from upstanding projections such asare encountered in conduits formed of two half sections of tile pipe with the pipe supports laid in the lower section. Therefore, there need be no interference between the various groups'of workmen performing the difierent operations necessary in constructing the conduit, and one portion of the job can be completed before the next portion is started.
It will also be observed that the side tile, top tile and pipe supports can be made in various complemental sizes and that the base A may be made of any desired size so that conduits of widely different sizes or capacity can be easily and quickly installed by various combinations of the sections. For example, the height of the conduit can be varied by using taller side sections, while the width of the conduit can be varied by using wider top sections on a wider base, and both the width and height of the conduit can be increased by utilizing taller side sections, wider top sections and wider bases. Sections of the various sizes can thus be kept in stock and combined for different jobs as desired.
- insulating material.
I Obviously'the partitions'51'will be laid after the side tiles 3 are set, and the pipe containing a chamber above the partitions maybe filled with suitable heat insulating material when'desired.
The upwardly converging sides of trapezoidal side tile 3 outside and inside of the conduit tend to facilitatev draining of exterior water away from the conduit and conduct interior moisture rapidly downwardly to the draining channel 2, respectively, and special fillings of crushed-rock, gravel, etc. and extra outside drain pipes to facilitate drainage are not required. All moisture within the conduit is quickly conducted to the drain gutter 2 at the bottom of the conduit, and this drain gutter canvbe interrupted atintervals by manholes and runoff drains for carrying the water to some suitable outlet. Furthermore, the hollow structure of the side tiles with'the longitudinal channelsserve as secondary drain channels for carrying off any moisturewhich may seep through the joints between the side tile, and said tiles also have high heat insulating qualities due to air in the chambers 4. The partition 51 fully protectsthe insulating material above it from moisture in thebottom of the conduit and prevents the drain channel from becoming clogged with the The longitudinal channels in the top and side sections enhance the'heatinsulating qualities of the conduit sections due to the confinement of air within the channels.
The pipe supports rest directly upon the base A so that no strains from the weight of the pipe supports or pipes are imposed upon the side walls or top of the conduit, and various sizes of the pipe supports may be utilized as required, while the elevations of the pipe supporting shafts may be varied as required by cutting off the legs of the brackets.
In all forms, the side tile are preferably provided with-exterior grooves 50 inthe joint surfaces for providing a bond betweenthe tile and the mortar. I I
