companying drawing.

This invention relates to improvements in culvert headers adapted for attachment to the terminals .or ends of sheet metal culverts or pipes, and has for its principal object to improve the construction and increase the efficiency and utility of devices of this character.

A further object of the invention is to provide a header of this character which is simple in construction, and which may be readily attached to the ends of culverts or pipes without structural changes therein.

A still further object of the invention is to produce a header of this type which will give additional strength at the ends of the culvert and serve as a means for protecting said culvert ends against injury by heavy traffic and loads.

Another object is to produce a header having a flaring mouth which prevents the water from breaking in around the culvert, and furthermore protects the earth in the immediate vicinity of the receiving and outlet ends of the culvert and prevents the same from washing away. In this connection it is to be noted that the earth being protected around the culvert ends or terminals, will necessarily be prevented from dropping in and thereby filling up and clogging the culvert.

A still further object of the invention is to construct a nestable header made of com-Y plementary sections which can be easily assembled and readily secured to the ends of culverts or pipes, thus facilitating handling and shipment.

Further objects and advantages will appear in the following 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 portion of a nestable culvert illustrating my improved header attached thereto;

Fig. 2 is a longitudinal section of the same;

Fig. 3 is a detached; Y

Fig. 4 is a side elevation, partly in section of a nestable header for use in connection with nestable culverts; y

Fig. 5 is a similar view ofy a nestable header used inconnection with the ordinary corrugated pipes or culverts;

Fig. 6 is a cross-sectional view talrenon the line 6 6 of Fig. 4; f

Fig. 7 is a cross-sectional view taken on the line 7+? of'Fig. 4, and

perspective view of the header FiU. 8 is a cross-sectionall view taken on the line 8-8 of Fig. A5.

Referring to the drawings, itisto be noted that the improved header herein re'- ferred to is adapted to be securely fastened to the terminals of corrugated nestable culverts, and without structural changes being made to such culverts. 'A portion of a nestable culvert is illustrated in theKdra-wings, the complementary sectionsl` and 2 .thereof being adapted to be connected together in a manner such as isy more particularly set forth and claimed in my Patent No. 1,049,86, granted January 7, 1913.v y

The particular type of header illustrated in Figs. l, 2 and 3, is made up of two parts, namely, a flared or funnel-shaped member 3, preferably of circular formation in crosssection, and a cylindrical collar 4, said collar being transversely corrugated. Iti's to be noted that the collar 4 is permanently fastened to the smaller end of the flared member 3 by any of the usual securing means, although preferably by the spot welding operation. The flared member is shown as transversely corrugated although this member may bev made of smooth or non-corrugated metal as may be deemed advisable. By making the flared member corrugated as shown, said member is materially strengthened as will beV obvious. As a further strengthening means for the header they flared member is provided at its outer or` larger end with a circumferential outwardlyV strengthens these terminals or ends and serves as a means for protecting the same against injury by heavy traflic and loads, and at the same time, providing an effective means for connecting the header to the terminal. Furthermore, the flared or funnelshaped member of the header will, in addition to its other functions, serve to deflect the heavy load to which the culvert may be subjected, and this due to its particular shape.

Referring particularly to Figs. 4 and 5 of the drawings, it will be observed that the culvert header is shown as being made up of complementary half sections 5 and 6, each section comprising a collar portion 7 and a flared portion 8 which are permanently secured together. These complementary secf tions 5 and 6 are provided along their longitudinaledges with metal strips 9, which strips are secured to the convex corrugations of each section, preferably by welding or riveting the same thereto. It is to be noted that key-receiving sockets or passageways are formed between the strips and the convex corrugations of the sections of the header, and that metal keys or clips l0 are provided for engaging within said keyreceiving sockets for fastening together adjacent strips of the complementary sections for the purpose of holding and retaining said sections in assembled relation.

In constructing these nestable headers for use' in connection with the terminals of nestable culverts, the connecting strips 9 of the collar complementary sections are arranged upon the inside of the collar sections and at the longitudinal edges thereof, so that said strips will not interfere with the nestable culvert sections when the same are clamped about the cylindrical collar of the header. This construction is clearly shown in Fig. e ofthe drawings.

In providing a nestable header of the type herein shown, it will be understood that the same can be used to great advantage in connection Vwith the ordinary corrugated pipeV or culvert, to` which it may be easily attached, the complementary sections of the collar portions of said header being clamped about the terminal or end of said culvert or pipe, as clearly shown in Fig. 5 of the drawings.

It will thus be seen that in providing a culvert header of the type herein shown and described, many advantages are obtained over any heretofore known, and in addition tothe usual functions performed by said Vheader, additional strength at the ends of corrugated metal pipes or culverts is provided, which, without the header, are eX- posed to abuse by heavy traiiic and loads, inasmuch as the corrugated collar gives double strength and the funnel-shaped member will deflect the load on account of its shape.

Having thus described my invention, what l claim and desire to secure by Letters Patent is 1. In a culvert, the combination with com-` plementary culvert sections, a header comprising a flared or funnel-shaped member and a collar permanently attached thereto, said header also being made up ofcomplenientary sections, the coniplementary'culvert sections and the collar of the header having overlapped relation one with the other, and means for fastening all complementary sections together in this overlapped relation, the fastening meansV at the overlapped portion of the sections for one set of complementary sections being located upon the outside thereof and the fastening means for the other set of sections being located upon the inside thereof.

9;. In a culvert, the combination with complementary culvert sections, a header comprising a flared or funnel-shaped member and a collar permanently attached thereto, said header also being made up of complementary sections, the complementary culvertsections and the collar of the header 'having overlapped relation one with the lar portions being located uponV the insideV thereof.

Yin testimony whereof l have aliiXed my signature in presence of two witnesses.
