To all whom it may concern.

Be it known that 1, JOHN H. Duels, a citizen of the U itec States, residing at Birmingham, in the county 01'": Jefierson and State of Alahaiiia, have invented certani new and useful Improvements in Sheet- Metal Culverts, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to sheetmetal culverts or pipes to be used as drains, aqueducts or the like, and more particularly to such culverts of the nestable type, wherein the same are built of sections adapted to be knocked down and nested together in ship ment and storage and to be 'set up and formed into a complete culvert or pipe at the place where the same is to be used, the application for this invention being a division 0- an application filed by me on April 22, 1914, Serial No. 692,326.

The principal object of the invention is to generally improve the constructioii'of such culverts and to provide a culvert which is strong and rigid in construction, cheaply made, and requiring a comparatively small amount or" labor in assembling the culvert sections to form a completed culvert.

A further object of the invention is to providea culvert which is made up oi? corrugated metal sections, preferably half sections, said sections having rigid metal. strips to the same at or near their longitudinal edges, so that when the sections are placed together with their; longitudinal edges meeting, adjacent strips or bars serve as a means to which metal fastoning .devices may be applied for holding In connection with this object of the invention, it is 'to be noted that the rigid strips or bars are connected directly to the convex corrugations of the culvert sections, in which event they also serve to materially strengthen the sections.

A still further object or" the invention is to provide a culvert of the type set forth, wherein the sections thereof are particularly adapted for nesting one within the other while being shipped or in storage, and fursections may be eas- 11y connected together without the use of bolts, rivets or similar fastening devices, or breaking away of the metal from which the culvert sections are made, thereby prolonging the life of the culvert.

Further objects and advantages will appear in 'fillQ'fOllOWlHg description, it being understood that various changes in form, proportions and minor details of construction may be resorted to within the scope of the appended claims.

I have illustrated my invention in the .accompanying drawings, in which:

Figure l is a side elevation of a culvert showing the sections of the same constructed in accordance with my invention, and further illustrating my improved straps or connecting bands for retaining the complementary sections in connected relation. Fig. 2 is a transverse sectional view of the culvert taken on the line 22 of Fig. 1, and Fig. 3 is a view showing a number of the culvert septions in nested relation one with the ot ier.

that each section, indicated at 1 of thc metal culvert is provided with corrugations which are arranged parallel with opposite ends thereof, and that when these sections,

which are preferably alt sections, are arranged in assembled position to form the completed culvert, the corrugations of upper and lower sections coincide with each other,

or in other words each convex and'concave corrugation of an upper section is directly in line with the convex The sections 1, as has been stated, arc'preferably half sections, and the same are con: structed without the usual outstanding flanges, but the longitudinal edges of complementary sections areadapted to abut as indicated at 2, so that when said sections are connected together with their longitudinal edges meeting or abutting, suitable improved means to be hereinafter described being provided for retaining them in such relation, the corrugated culvert, for all intents and purposes, has the appearance and strength of an'integral corrugated cylinder.

The culvert sections are provided along their longitudinal edges with rigid metal strips or bars 3, which aresecured to the convex corrugations of each section preferably by weldin or riveting the same thereto. In the pre erred embodiment oimyin Referring to the drawing it is to be noted and concave corru- 'gations respectively of the section below it.

greatly str en. the sections and retain L'- i, K m n v them in. sh pe. ihese SlulPS 3, however, made of short sections arthe prays ranged intervals along the longitudinal edges of the m vert sections, this construction being cally claimed in a companion application, Serial Number 720,527, filed Sept. 30, 1915.2.

in assembling the sections of this culvert with the longitudinal edges of upper and lower sections abutting the metal strips or bars 3 0i. complementary sections are ar- 0 lie adjacent one another, and in this retion and when the same are fastened or ii d together, serve as a means for retaininathe sections in connected relation for toi-ming the completed culvert. These adjacent strips of complementary sections, as hetero referred to, convert corrugations of the sections, and ,are preferably arranged upon the outside of said sections, and it will be noted that passage-ways indicated at at are formed between the corrugated culvert sections and the said. metal strips at points intermediate the com cs: corrugations o't said sections, and these pasagewuys to receive the metal 1" wing devices 5, which are in the straps or connecting bands, and are provided ior fastening adjacent s together for the purpose of holding sections in connected relation. These straps or connecting bat-Ids illus rated in. drawing,

It is to be here noted "that complementary sections are connected together at points intermediate the convex corr mist-ions of the sections, and this is rend-cred po )le by reason of the tact that the metal strips which are connected to the longitudinal edges said sections are only connected to the convex corrugati ns thereof. so as to leave passagebetween the, sections and the metal st, a points intermediate the convex corrugm.

are connected to the- 5, as clearly, are adapted to.

, The particular purposd of the metal strips, as before mentioned, is to provide a connecting means between the complementary culvert sections, but these strips also serve as a means for supporting the sections in nested relation. In this connection it will be noted upon referring to Fig. 8 of the drawing, that when the sections are in nested relation the inner longitudinal edge 7 of each metal strip rests upon the longitudinal edge of the section below it, thereby allowing the sections to be neatly nested and supported one'within the other.

In arranging the sections to vert any number thereof may be employed to produce the desired circumference, but usually two sections only are necessary, preferably arranged as lower and upper complementary sections. It will be noted that the sections of the culvert embodying this invention, may be all alike, thus making different kinds it unnecessary to keep two form a complete pipe of sections in stock to or culvert. j

Many advantages are obtained by a construction of sheet metal culvertalong the lines, as herein specified, some of which advantages have already been set forth in the objects of this invention, and it will be perfectly obvious that the assembling of the parts is simple and effectual and is of such a character that it may be accomplished where the work of installing a culvert is being carried on. It is to be further noted that the sections are constructed without outstanding flanges and that the complementary sections are adapted to be connected together with their longitudinal edges abutting, without the use of bolts, rivets or similar fastening devices engaging the metal sections themselves.

laying thus described my invention, what I claim is 1. A sheet metal culvert comprising complementary sections, a metal. strip or bar secured along each longitudinal edge of said sections, and a strap or connecting band engaging one of said sections and fastened to the metal strip of the opposite section for retaining the sections in connected relation.

2.. A sheet metal culvert comprising complementary sections, a metal strip or bar secured along each longitudinal edge of said sections, and a strap or connecting band adapted to straddle one of the sections and to be secured to the metal strips of the 0pposite section for retaining said sections in connected relation.

3. A sheet metal culvert comprising complementarysections, and a strap or connect ing band adapted to straddle one of the sec tions and to be secured'tothe longitudinal edges of the oppositoa ction for retaining said sections in connected relation.

4. A sheet metal culvert comfiri'sing commemes plementary corrugated sections, a metal strip or bar secured in the convex corrugations of each section aleng each longitudinal edge thereof, fliereby forming passage-Ways between said metal strips and. the sections themselves, and strap 01 connecting bend adapted to straddle one of the sections, the ends of said strap or band adapted to be inserted Within tie passageways and bent over the metal strips of the opposite section 10 for retaining said sections in connected relation.

In testimony whereof I have aflixed my si -nature in presence of two Witnesses.
