To all'whpgt-may concern:

j Be ity'known that L'OHARLES E. GLASS- 1 POOLE, vajjcitizen of the UnitedStates, resid-V w i ;ng at St." aul, in .the county'of Ramsey and` State of Minnesota, have invented a new and 1 useful Improvement in Culverts, of "which thefollowingis aspecication..

culvert; Fig. 5 is a longitudinal section of culvert showing a modified construction, and

Eig. G .is a4 ransverse section taken on the hne Y-Y o `ig. 5l

In the drawings A represents a' section of culvert having my invention which is in the f orm of a pipe the ends of lengths 2 and 3 'of which are joined together in the following manner to form a complete line of culvert;

.The section of culvert as shown is provided with upper and lower longitudinal parts which 'are' respectively corrugated at 4 and. .smooth at` 5 t e corrugations of the former running transversely and in .cross section ap- `pearmglin the form of reverse curves, o r of er suitable form' or shape desired for` the purp'se of reinforcing the strength of the` thin sheet metal or other material out 4of whichthe culvert is preferably made.

Y The 'upperand lower parts of the culvert. are intgral being made out of a single sheet of material. The sides of the sheet are connected by a lap joint B. the parts of which are .secured to ether-by means of -rivets 6. welding or botl as desired. The lower part ofthe culvert has a smooth inner surface and is not rovided with corru ations, -so that when t e culvertis in use a 'of the Waterin it flows out and is notheld by the intersti'ces between corru ations as when the latter entireliy encircle t e culvert.

T to nearly circumscribe the culvert when desired but never entirely encircle the culvert within the scope of my invention. The

method of joining thelengths at (l as shown consists of securing one. end of the length 2 over the vadjoining end of .length 3. VAfter these parts are connected in the .manner described the rivets are secured in place to complete the joint B.,

vIn the modified construction shown in Fig.

3 the lower or smooth portion ofthe endsof the culvert at the joint C are secured ether by rivets 6 for the purpose of increase `corrugations may be varied in length? ing the strength of the joint and it isobvious that this method' of securing 4the parts together may be varied as desired.

In forr'mn the sheet to make the culvert out of a sing e piece .of material, the corrugations are ressed into the sheet while lyln flat and efore it is bent into cylindrica shape and in order to revent distortn the lane ofthe material t e sheet is held 4rmly in place by jaws -nr other'suitable means so Q COPY 901,703v

hilo this culvert is shown of substen.- tially hollow cylindrieui shape yet it is obviof e. single piece of sheet meta-l ous that it may be made of any suitable cross sectional design desired and the-t the corrugated part muy extend a greater or less distance up or down at the sides of the culvert.

It is also obvious that the culvertinay bef' curved orotherivise shaped longitudinall'y3g Whenidesired and While described es being mede out of metal it may be Inadesuccess-- fully out of other suitable' material.

`In Fig. 5, longitudinalcorrugation 7,is

formed in each side of the culvert for the purpose of allowing expansion and contraction ofthe materiel. Such longitudinal corruga- .l tions-'it will be noticed do not tend -toob-.g structthepissage or hold any waterin inte'rstices as witli trun'sverse' cirrugutions. "In
