Description

Dec. 2, 1930. w. E. BABE 1,783,597 I SHEET METAL CULVERT Filed April 2, 1929 //l //V70R W f. 51475 C Patented Dec. 2, 1930 UNETE PATENT OFFICE WILLIAM ELWOOD BABE, OF OSI-IAWA, ONTARIO, CANADA, ASSIGNOR TO THE PEDLAR PEOPLE LIMITED, OF OSHAWA, ONTARIO, CANADA, A JOINT-TOOK COMPANY SHEET-METAL GULVERT Application filed April 2, 1929. Serial No; 351,953.
My invention relates to improvements in sheet metal culverts, and the object of the invention is to devise a culvert of this type which will have maximum durability, which will provide free, unobstructed water flow, and may be easily freed from accumulated matter or ice or snow, which will provide complete drainage so that there will be no pocketing of moisture in the culvert bottom tending to corrode the same, and in which any sediment lying at the bottom of the culvert will not be held in corrugations, and it consists essentially of the arrangement and construction of parts as hereinafter more particularly explained.
Fig. l is a perspective view of a portion of a sheet metal culvert constructed in accordance with my invention.
2 is a longitudinal sectional view through Fig. 1, taken on line 22, Fig. 3.
Fig. 3 is a transverse sectional view through the culvert.
l and 2 are two culvert sections. Each section is formed with an upper corrugated peripheral portion, the corrugations extending transversely of the section. The lower peripheral portion of the culvert is depressed as indicated at 4 so as to form a trough-like depression having a smooth surface free from corrugations so that any water or moisture accumulatin at the bottom of the culvert will have a free flow over such surface, and thereby provide for complete drainage.
The longitudinal edges of the portion 4 are formed into shoulders 4P which serve to reinforce the culvert section longitudinally. The sections of the culvert fit one into the other in the usual manner and are connected together by tie-plates 5 the overlapping ends of the culvert sections.
Each tie-plate 5 is provided with a central corrugation 7, forming an exterior rib around the lower portion of the culvert, serving to engage the ground surface in which the culvert is embedded and thereby prevent longitudinal movement. Although I show the tie plate 5 located at the joint between the culvert sections, it will of course be understood that they might be placed at suitably spaced riveted as-indicated at 6, to
apart points along each section of the culvert as found desirable.
By the construction above set forth it will be readily understood that I have provided a sheet metal culvert which will be rendered strong and durable by reason of its corrugated upper portion, and at the same time will provide for the free flow and drainage of water along the lower surface of the culvert, eliminating the formation of pockets in which matter may accumulate or ice and snow congregate. W hen the lower portion of the culvert is corrugated, the ice and snow particularly engage in such corrugations so that it is impossible to clear the culvert until such ice and snow has slowly melted.
Also by forming the lower portion of the culvert with corrugations pockets are formed in which water is retained for a considerable length of time which thereby tends to corrode the interior surface of the culvert, reducing the life thereof.
l/Vhat I claim as my invention is A pair of corrugated sheet metal pipes inserted at their ends one within the other so that the end corrugations interengage, and a semi-cylindrical tie-plate adapted to fit the engaging corrugations and to be riveted at one side to one pipe end at the one side of the engaging corrugations and at the other side to the other pipe end at the other side of the engaging corrugations.
