@EECFICATION forming part of Letters Patent No. 491,408, dated February 7, 1893.

Application tiled November 5, 1892. Serial No. 451,028. (No model.)

.To @ZZ whom, may concern.:

Beit known that I, CHARLES B. DAVIS, ot Savona, in the county of Steuben and State of New York, have invented a new and Ifnpreved Culrert, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved culvert, which is simple and durable in construction, readily set up in place, and cheaply manufactured.

The invention consists of two series of curved metallic plates placed one on top of the other to break joints, and riveted together to torni a double-walled arch.

The invention also consists of certain parts and details, and combinations of the saine, as will be fully described hereinafter and then pointed out in the claims.

Reference is to be had to the accompanying drawings forming apart of this specilication, in'vwhich similar letters of reference indicate corresponding parts in all the iigures.

Figure l is a front elevation of the improvement as applied; Fig. 2 is a longitudinal section of the saine; and Fig. 3 is a sectional,

B are fastened together by means of suitable rivets C or other devices, and a desired number ot plates are joined in the manner described so as to forni an arch of the desired length 5 that is, corresponding to the width of the culvert to be built. The plates A are formed at their ends with inwardly bent `flanges D, and corresponding flanges E are formed on the outer plates B and extend in au opposite direction, that is outwardly, to the flanges D, as will be readily understood by reference to Fig. l. The flanges D and E forni a toot for the arch composed of the metallic plates, and rest on a suitable foundation F builtin the banks of the culvert. Stones or other suitable materials are placed on top of the metallic arch to build the culvert in the usual manner. As shown in the drawings a stone facing is set on the ends of the metallic arch, and the space between the facings is filled in with earth or other material to the desired height. A culvert built in Y this manner is very durable, and the arch can be quickly set up and the tacings and fillings put in position without requiring inuch skill.

Having thus fully described my invention, l claim as new and desire to secure by Letters Patent;-

l. A culvert provided with a metallic arch composed of curved plates placed one on top of the other to break joints, and riveted together, substantially as shown and described. 2. A culvert provided with a metallic arch comprising two sets or series ot metallic plates placed one on top of the other to break joints, rivets for fastening the two series of plates together, and anges formed on the ends of the said sets of plates and bent on opposite directions to form a foot for the arch, substantially as shown and described.
