JULIUS H. SCHLAFLY, OF CANTON, OHIO, ASSIGNOR TO THE CANTON CULVERT COMPANY, OF CANTON, OHIO, A CORPORATION OF OHIO.
Specification of Letters Patent.
Patented Jan. 3, 1911.
Application led January 4, 1910.1 Serial Nol 536,395.
To all whom 'it may concern:A
Be it known that I, JULrUs I-I. SCHLATLY,
a citizen .of the United States, residing at and well adapted to the purpose for whichl it is intended. I attain this object, and other objects readily apparent to those skilled in the art, by the construction illustrated in the accompanying drawing, in
- which- Figure 1 is a .perspectiveview of a draining culvert embodying my invented im-,
that portion of the culvert where longitudinally adjacent upper sections over-lap. Fig. 4 isa side elevation illustrating two upper sections and a lower section properly connected together and the flange of the lower section broken away to disclose the construction.
Throughout the several views similar numerals of reference indicate similar parts.
The numeral l indicates a bottom section, preferably formed with a plain, flat upper surface and having side or retaining flanges 2 along both longitudinal'edges. The numeral 3 indicates one of the upper sections while 3a indicates a similar section longitudinally adjacent to the section 3. Each upper section is preferably arched or curved and is provided along its longitudinal edges with the integral flan es 4. Circumferential corrugations extend rom the outer edge of the flange on one side to the' outer edge of extending not only throughout the arched portion of the section 'but through the flanges 4. The purpose of the corrugations in the arched portlon of the culvert is to strengthen the same and enable it to withstand the crushing pressure of the earth immediately above it, while the corrugations in the flanges 4 strengthen said flanges and provide a broad bearing to support the arched portion, the said flanges having less tendency to bend along the line of their attachment to the arched portion and in fact throughout their width by reason of the strengthening corrugations, and thus distribute the weight or pressure over a substantially larger surface. A further purpose of the circumferential corrugations 1s to conduct water to the draining apertures, as hereinafter described.
In erecting thevculvert lon itudinallyadjacent upper sections are overapped at thelr meetin ends one full corrugation, as .illustrated 1n Figs. 1 and 4 and bolts 5 or their equivalents are used for the purpose of connecting the upper sections to the lower sections. The apertures 6 in the flanges 4 are elongated transversely with respect to the culvert for the purpose of permitting ad]ust ment of the upper sections relative to the lower sections so as to bring the edges of the flanges 4 against the lianges of the lower sections as illustrated in Fig. 3` and also to permit of some slight adjustment of the u per and lower sections when either surroun ing groundor water within the culvertv itself is frozen.
In the arched portion of each upper section are arranged a number of dralningapertures 7, which apertures are preferably located in the externally concave surfaces Vformed by the circumferential corrugations to increase the draining efficiency. When water haspercolat'ed through the soil and come into Contact with the surface of one ofthe upper sections it will be directed along -said surface into the nearest concavecorrugation, whence it will flow circumferentially along the side of the section to the first aperture in lits pathway and .through said laperture into the interior of the culvert. In placing culverts of the character herein described it is desirable to provide a firm and smooth foundation for the low'er section-and to fill in around the top section a quantity of coarse gravel or broken stone to aid in the rapid draining of water from the surrounding soil to the surface of the upper sections, whenceit will be carried into the-interior of the culvert as just described.
It will be noted that while my draining culvert may be used to advantage in practically all places where an ordinary culvert might berv used, yet it is especially designed for draining fills on railways or in other placesvwhere it is desired to combine a means or conduetlng water with a means for draining the surrounding ground.
The culverts may be shipped in a knockeddown and nested condition and a culvert of any desired length may be formed by connecting up the necessary number of sections. Both upper and lower sections may be made in.any desired or convenient length, joints between longitudinally adjacent upper seetions being preferably arranged intermediate joints between longitudinally adjacent lower sections.
It will Ibe noted that by reason -of the transverse corrugations in the flanges 4 the said flanges do not lie fiat against .the lower section but contact with said section only where the corrugations in saidfianges are convex on the underside, as clearly ill-usn trated in Fig. 4. Intermediate each two sion or rusting of the meta-l.
points of contact is an air space 8 produced by the upwardly'convex corrugation, said air space permitting the rapid dryin of water from between the contacting suraces of the flanges 4 and the lower section and thus to a large extent preventing the rapid corro- Attention should also be called -to the fact that a oertain amount of water will enter the 'culvert j by coming in `contact with the upper surface of the flanges 4, following said surface to the edge of the flange and seeping downwardly between the flange 2 and the edge of the flange 4', whence .it will be readily conducted under the flange 4 to the interior of the `culvert through the spaces 8.
Thile I have illustrated and described the lupper sections asvarched I do not desire to be confined to that construction as it is evident that said sections might be formed of an inverted V-shape or otherwise and also other minor changes of form or detail might be made without departing from the spirit of the invention.
