Il, 'iM/,347,

To ai?, whom it' may concern.-

Be it known that LKARL JOHAN THonsY, a subject of the King of Norway, residing at alland,` inthe county of Alameda and State of California, have invented certain new and useful liuprm'ernents inMetallic Culverts, of which the following is a specifica-tion. f

lily invention relatesto the class of culverts, drain pipes, and the like, and especially to structures of this nature made of sheet metal.

My invention consists in a sheet metal culvert or drain having its end fitted with a novel' rein forcing member.

lt also consists in the novel fitting and arrangement of said reinforcing member, as l shall hereinafter fully describe.

My invention is vapplicable to culverts, such as are used for drainage under railroads. highways, or in other places where a durable culvert or drain pipe is required.

The objects and advantages of mty invention will be fully set forth hereinafter, and

.y will be better understood from an inspection of the accompanying drawings, in which- Tfigure l is a side view, broken, of an end section of a culvert or of one end of a culvert, showing-the reinforcing member in its seat, but Anot fully covered therein at its meeting ends. Fig. 2-is an end View of the same, showing the covering ton ue bent home. Fig, 3 is a section, enlarge on line wwe of Fig. 2. Fig. is a section, enlarged, on line 41/--3/ of Fig.v 2. Fig. 5 is a side View, broken,A showing the application of. the reinforcing member to a. part circle culvert. ll1 ig. 6 is an end View7 partly in section, of the' same.

In Fics. l and 2, theculvert shown is a full circ e. and is made of corrugated-sheet metal. Fig. l may indicate either one end of a culvert, or it may represent one end of one of the end sections of a culvert. In the foi-nier case each end of the culvert is to be fitted with the reinforcing'- member; and in the latter case but one end will have said reinforcing member, while the other end section of the` complete culvert will have its free end provided with the reinforcing member, the intention in all cases being to reinforce both ends of the eiilvert.

in Figs. l to the culvert is l, and the reinforcing member is a rod 2. The end of 'specification of Leiters raient.

Application led October 30, 1911.

ltatented Serial No. $7,466.

the culvert l is bent over at 3 to form a channel in which is seated the rod ln order to make a proper joint where the sides of the culvert plate overlap and to cover therod 2 where its ends meet, the inf nerlying side of the culvert plate is cui in from the end along a line above the 'edge of the outerlying side, thereby forming a tongue et; and the end of theouterlying side is entirely cutaway to the Width of the over-.

ally used in street work or Where the head room is limited and a large water way is called for, the reinforcing rod 2 will be covered in the bend ,3 of the part circle culverts 5 of Figs. 5 and 6.

It will be noted that in both culverts, full round and part round, when they are of the corrugated metal type, the channel formed by the bend 3 has for its inner portion the bottom ofal furrow of the corrugation.

By my invention I am able to provide a metal culvert or drain pipe of increased strength at the extremities, thereby guarding against the'impact of debris, rock, etc., or whatever would tendi to distort the true shape of the ends and thus obstruct thev water way. A culvert tlnis reinforced at its ends, especially one which is of comparatively large diameter and made of thin sheets of metal and which would, not of itself bear a load likely to be placed upon it, is thus made capable of sustaining heavy travel. This reinforcing rod also acts as a guard against the effects of rough handling during shipping, transportation and installing which in most cases is hard to prevent, especially where the'culvert sections are of large diameter and great length.

It is also to be noted that a reinforcement as herein disclosed is lespecially advantageous in a culvert made of corrugated sheets, where by reason of the corrugations than its extreme ends. vWith an end reinthe pipe itself is of much greater strength forcing rod this difference will be elimi-l nated andthe end of the pipe will beV of equal strength with its body. Moreover in this' corrugated type of culvert, by having for the inner portion of the peripheral channel the bottom of a furrow of the corrugation, the reinforcement is compact Aand does not project unduly from the general surface of the culvert; it will not, therefore, be as liable to injur l;

Having thus described my invention what l claim as new and desire to secure by Letters Patent isy l. A sheet-metal' culvert of the corrugated metal type having its end bent to form a peripheral channel, the inner portion of which is the bottom of a furrow of the corrugated metal and a reinforcing member seated in said channel.

2. A sheet-metal culvert of full round section with overlapping sides, the innerying side being cut in from the end. to form a tongue, and the corresponding portion of the outer-lying side being removed, the end i l l i i i of' said culvert and the said itongue being bent to form a peripheral chinnel; and a reinforcing member seated in said channel.

3. A sheet-metal culvert of full round. 25

section with overlapping sides, the innerlying side being cut in from the end to form a tongue, and the corresponding portion of theonterlying side being removed, the end of said culvert and the said tongue being bent to form a peripheral channel; and a reinforcing member seated in said channel, and so disposed that its meeting ends are covered by said tongue.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

KARL JOHAN THORSBY.
