To all whom it concern: i
Be it known that I, JAMES B. JARMIN, a citizen of the United States, residing at Spokane, in the countyfof Spokane and State of Washington,A have invented a new and useful Flat-,Bottom Culvert, of which the following isa specilication.
This invention relates to improvements in sheet-"metal culverts and the object of the invention is to provide a culvert which will possess the maximum strength and whichmay be-readily assembled at the place Where it is to be used and which will be of such form as toe'ectually resist the crushin strain.
The mvention consists in certain novell features of the device illust-rated' in the accompanying drawings," as will be hereinafter described and claimed.
In the accompanying drawings, Figure l is an end view partlyin section of a culvert embodying my present invention. Fig. 2 is aside' elevation of a portion ofthe culvert.
In carrying out my presentainvention, I form the bottom of the culvert of a sheet metalv plate 1 which is transversely corrugated but which is fiat when viewed transversely. i y
The body of the culvert consists of a sheet metal plate 2 which is also transversely corrugated which is bent into a semi-circular or arch form having vertical side portions 3 and horizontal flanges 4 extending outward from the lower ends of the said vertical side portions. These horizontal flanges areprovided at intervals with openings adapted to register withsimilar openings in ,the fertiges., of the base portihinndf'su'itble securing bolts 5 are inserted through the said openingsto secure the members of the culvert together.
The culvert is formed in sections which maybe shipped in a knock-down or nested conditionand assembled at the place where the culvert is to be located. In assembling the part-s, the horizontal lianges on the sides of the body 2 are placed on the -u per faceof the base portion and bolted rigi y to the same, the meetin ends of sectlons of the body portion over apping so that there will be no open joints formed in the finished culvert through which dirt might filter or leak into the 'culvert to obstruct, the' passage through the same.
By constructing the culvert of corrugated sheet metal ample provision'is made for expansion and contraction under changes in temperature while the peculiar mannerl of connecting the sections employed by me effectually resists any tendency of the body of the culvert to spread and thereby separate from the base. vThe flat corrugated bottom provides a very stiff base and 'prevents'sinle ing of the edges of the arched shaped body under the weight placed upon the same while the provision of the horizontal flanges on the sides 'of the said bottom increases the bearings'urface and prevents the eX anding or spreading out of the' bottom of t e body.
Having thus described my invention, what I claim is:
A sheet metal culvert 'comprising a fiat bottom, and an arched body having vertical side walls, and horizontal flanges at the lower ends of the said walls rigidly secured to the upper side of the flat bottom, the bottom and body being transversely corrugated and made in sections.
. 'In testimony that I'claimthe foregoing as owmIhav-e hereto yaffixed my signature in the presence of two witnesses.
JAMES B. JARMIN.
