ROBERT MASON HEREFORD, OF NEW ORLEANS, LOUISIANA.
METALLIC CULVERT.
Specification of Letters Patent.
Patented fin 11%, 1913.
Applieatioii filed June 2d, 1913. Serial No. 775,600.
To all whom it may concern:
Be it known that I, ROBERT M. HEREFORD, a citizen of the United States, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented certain new and useful Improvements in Metallic Culverts; and I do hereby declare the fol lowing to be a full, clear, and exact description of the invent-ion, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to improvements in metallic culverts, and it is especially appli' cable to corrugated culverts made of iron or steel, in which the culvert is made up of a series of joints linked together. S11Gl'1;c11l verts frequently becomeclogged up with earth, or other solid matter, and it is dithcult to. clean out the same. This objection is in a large measure obviated by the apparatus herein described.
Reference is had to the accompanying drawings, in which Figure 1 shows a series of sections of corrugated culverts connected together in the usual way, alternate sections being provided with removable covers; Fig. 2 shows a section along the line 22 of Fig. l; and Fig. 3 is a perspective view showing one of the sections of the culvert with the removable cover applied thereto, parts being broken away.
rshows a section of the ordinary corrugated culvert, and 2 a similar section with the upper portion thereof cut away,-as at 3, near the edges of which cut away portions the angle irons l are attached. These angle irons serve not oiny to stifien and brace the cut-away portion of the culvert, but are spaced far enough from the cut-away edges 3 to leave a shoulder 5 on each side of the opening on which rest the edges of the rematerial as the. body of the.
movable cover 6, which cover is of similar culvert, and is held in place by its own weight and by the earth, or other material, piled above the same. In the ordinary fitting of the parts, there will be clearance space enough to permit the insertion of a crow bar, or other tool,. for lifting the top of the cover incident to removing the same from the culvert when desired. It will be obvious that no especially snug fit is necessary. These open top sections 2 of the culvert may be arranged alternately with the closed sections 1, or the open top sections may be spaced at any suitable distance apart, depending upon the na ture of the use to which the culvert is subjected.
The corrugations in the arched cover will give it the sufficient rigidity against compressive strains, and the inner walls of the angle irons 4; will prevent the cover from being flattened out too much, or from lateral displacement relative to the opening in the 5' top of the culvert.
Having thus described my invention, what I claim and desire to secure by Letters Patent of the United States is Y 1. A corrugated culvert consisting of a plurality of peripherally closed sections, with intermediate sections cut away at the top thereof and provided with loose arched corrugated covers adapted to close said 'open-' ings, and with stilfening bars secured near each side of said openings and adapted to engage the edges of the covers, substantially as described.
2A corrugated culvert consisting of a plurality of peripherally closed sections, 8 with intermediate sections cut away at the top thereof and provided with loose arched corrugated covers adapted to close said openings, and with angle irons riveted to the latter sections near the openings thereof and 5 adapted to leave a shelf to support the edge of the covers, and the said angle irons engaging the outer edges of said covers, substantially as described.
In testimony whereof, I affix my signa- 9 ture, in presence of two witnesses.
ROBERT MASON HEREFORD.
Witnesses J. E. QUINN, Geo. FREDRIOK BRANTLEY.
