concnnrrn CULVERT.

Specification of Letters Patent. Patented June 20, 1911.

Application filed March 31, 1911. Serial No. 618,086.

J. BURns, a

This invention relates to certain new and useful improvements in concrete culverts.

The primary objectof my invention is to provide a strong, comparatively inexpensive culvert, to serve as a transverse train or waterway under country roads, railroad beds and the like.

Another object is to provide a culvert, with an earth holding top flange and two divcrgently extending wings, serving as retaining walls at each end of theculvert.

With these and other objects in View the present invention consists in the combination and arrangement of parts as will be hereinafter more fully described and finally pointed out in the further understood that changes in the specific structure" shown and described may be made within the scope of the claim, without departing from the spirit of the invention. I

In the accompanying drawings forming a part of this specification, and in which like numerals of reference indicate similar parts in the several views: Figure 1, shows an end view of a culvert constructed according to my invention showing the same in position. Fig. 2, shows a transverse sectional View.

Fig. 4, a top view.

In my present invention I provide a concrete culvert which is preferably made directly in the cut or at the point where the conduit is finally to rest. A. road culvert should be so constructed that it will withstand the heaviest load which is likely to pass over the same, while also including feas tures insuring the water being carried States, and a resident appended claim, it being what I claim as new and desire to through the culvert without washing away the side earth or draining under the culvert.

A tubular culvert including the above desirable features, I show in the accompanying drawings in which the numeral 1, designates the lower half of the culvert and the numeral 2, the upper half.- The culvert is of a suitable length and is traversed from end to end by a cylindrical drain opening. As

shown in Fig. 2, the upper half of the conduit 1s of a greater thickness thanthe lower.

half and has its opposite faces 3, flattened,

the upper half being arched from the fiat faces 3, as shown at at.

As disclosed in Fig. 2, a narrow lengthwise running ledge 6, is formed at the base of each flattened side 3, these ledges 6, assisting in retaining and supporting the faces 3. The culvert at each upper end is slightly enlarged as shown at 5; in Fig. 3,

, and each upper end is further provided with a skirting arcuate flange-7.

Extending from each end of the culvert, are two similar wings '10, 10, these wings extending obliquely outward fromthe ends as shown in .Fig. 4:, the bottom edge l1, of these wings extends in a plane forming a tangent to the culvert proper. It is of course understood that these culverts are made of various lengths and capacities. The face of each culvert end at the lower portion is further provided with an outwardly extending lip 12, as shown more clearly in 3, to insure the water washing into the culvert and preventing the water from seeping under the culvert.

A culvert constructed according to my invention is simple, and inexpensive in construction and both durable and efficient in operation.

Having thus described my said invention, secure by United States Letters Patent is As a new article of manufacture, a tubular culvert traversed from end to end by a cylindrical drain opening, the upper half the earth and holding earth-adjacent to the of said culvert being pf a greater." thickness ing in a coinmon plane extending tangenthan the lower half'end having 'tWo opposite tially t0 the bottom part of said culvert. 10

flat faces each ending in a narrow length- In testimony whereof I affix my signature, Wise ru ning ledge, the culvert at each upi in presence of two Witnesses. I per end being slightly enlarged and ending 7 ROBERT J. BURNS. in a skirting flange, two retaining Wings Witnesses: 1 obliquely extending from each end of the JOHN J.
