CULVERT.

1 '0 all whom it may concern:

Be it known that I, WILLIAM B. STAM- of the United States, residing at VVoodsboro, in the county of Frederick, State of Maryland, have invented certain new and useful Improvements in Cul-' verts; and I do hereby declare the following to be a full, clear, and exact description of the invention, such-as will enable others skilled in the art to which it appertains to make and use the same.

The present invention is directed to improvements in sheet metal culverts.

The invention has for its object toprovide a simple and practical connection for edges ofthe semi-cylindrical sections.

A further object of the invention is 'to so construct a connection of this type which is simple in construct-ion, durable, and one which may be manufactured at a minimum cost.

With these and, other objects in view, this invention resides in the novel features of construction, formations, combinations and arrangements of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawing, in which Figure 1 is a side elevation of a portion pf a culvert showing the sections connected 1n accordance with the invention. a transverse sectlonal view. Fig. 3 tall perspective Fig. 2 is is a deview of the connection.

Fig. 4 is a-similar view ofa slightly modified form of connection. Fig. 5 1s a transverse scctional view through the culvert showing the modified form of connection applied thereto.

Referring to the drawing, and 2 designate upper and lower sections, respectively, said sections being constructed of sheet metal and are semi-cylindrical in cross section. Each section is transversely corrugated, as indicated at 3, said corrugations being arranged annularly and extend the entire width of the section.

Adapted to seciirethe meeting longitudinal edges of the respective sections 1 and 2 are connections 4 which consist of a horizontally' disposed web 5 having formed integral with the sides thereof plates 6, said plates being arranged in spaced parallel re lation to form open grooves opposing faces of the plates 6 are formed Specification of Letters latent.

with vertically arranged corrugations 9, corrugated formation of the longitudinal edges of the sections 1 and 2 so that said edges will fit snugly within the

grooves

7 and 8, thus securely connecting the sections and preventing both relative lateral and longitudinal movement thereof.

In practice the lower sections 2 are first laid with their meeting ends arranged in e connections 4 are placed upon the longitudinal edges of the thus'laid sections with the rooves 8 engaging said edges, whereupon t e upper sections 1 are placed with theirlongitudinal edges engaging in the grooves 7 and resting .upon the uppersurface of the-web 5 of each connection, thus securely holding the meeting longitudinal edges of the respective sections. The meeting ends of the sections 1 and 2 are arranged so as to break joints, and the meeting ends of the connections are likewise arranged with respect to the meeting ends of the sections, thus producing a thoroughly water-tight culvert.

In the modified form of the v invention, as shown in Fig. 4 th e connections 10 consist of of. the sections, said plates being provided with perforations 12 near their opposite ends, said plates being connected by bolts 13 which hold said platesin clamping engagement with edges of the respective sections.

at is claimed is 1. -A culvert comprising semi-cylindrical upper and lower metal sections formed with annularly arranged corrugations through out their width, a connection consisting of a horizontal web having formed integral therewith vertical plates arranged in spaced parallel relation to form oppositely disposed open grooves for receiving the respective longitudinal edges of the sections, said plates having their opposing faces formed with corrugations to engage the corresponding corrugations of said sections, as and for the purpose set forth.

2. A culvert comprising transversely arched and "corrugated sections having their corresponding longitudinal edges opposed in spaced relation, retaining members disposed respectively against the inner and outer faces of the longitudinal edge portions of the sec- 1 a pair of plates 11, both faces ofwhich are corrugated to conform to the corrugations the longitudinal meeting,
