IMPROVEMENT IN CAST-METAL GUTTERS FOR STREETS.

Specification forming part of Letters Patent No. 146,652, dated January 20, 1374; application filed December 13, 1873.

To all 'whom it may concern:

Beit known that I, JOHN P. BYRNE, of Louis` ville, in the county of Jei'erson and State of Kentucky, have invented certain new and useful Improvements in Cast-Metal Gutters for Streets; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompany, ing drawings and to the letters of reference marked thereon, which form a part of this speci.- iication.

The nature of my invention consists in a concave gutter of cast-iron or other suitable metal, as will be hereinafter more fully set forth.

In order to enable others skilled in the art `to which my invention appertains to make and provided with a portion of its upper surface a depressed, so as to form a rabbet equal in depth to the thickness of the plate at its other end b, so that when the end b of the next plate is laid, resting on the rabbet a of the first section, the upper concave face of the gut-ter forms an even, continuous surface-line. For corners,

the ends of such` curved section being constructed in the same manner as described for the straight sections A A. Each section ot this gutter is provided with a vertical iiange, c, under each edge, projecting down a suiiicient depth to form a wall, against which the general pavement rests. These vertical ilan ges c c are as much shorter than the whole length of each section as the length4 of the rabbet a., and located on each sect-ion one-half such length of rabbet a from each end of each scc tion, thus locking the sections together in a continuous line on both sides, and preventing any one from moving laterally in the rabbet a. For example, if the whole length of a section be four feet and three inches, and the rabbet three inches long, then the vertical iianges c c would be four feet long, located one and a half inch from each end of the section.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is y A concave met-al gutter made in longitudinal sections, and each section provided with a rabbet, a., and vertical side flanges c c, constructed and arranged substantially as and for the purposes herein set forth.

In testimony that Iclaim the foregoing as my own I aiiix my signature in presence of two witnesses. l

JOHN I). BYRNE.
