Specification of Letters Patent.

Patented Dec. 1, 1908.

Application filed June 18, 1908.' Serial No. $39,268.

To all whom/"it may concern:

Be it known that we, ANDREW A. CUM- MINGS and DANIEL S. DEMPSEY, citizens of dinal edges and having flanges at said lon-' the United States, residing at Little Genesee and Bolivar, respectively, in the county of Allegany and State of New York, have invented certain new and useful Improvemerits in Sluices, of which the following is a specification.

- The present invention provides a sluice, culvert, or like water-way of novel construction, the same being formed with a view to economize in material, provide a simple construction and to devise an article of the 'character'aforesaid which will not become deranged either by settling or by frost.

The invention consists ofa sluice or culvert deflected intermediate of its longitugitudinal edges to form supporting means to prevent settlement and. to provide anchoring means to overcome the action of frost and prevent lifting of the sections in cold weather by the frost penetrating the ground and reaching the devlce, saidflanges eing provided by angle strips equal in length to that of the culvert-and attached 1 fisclaimed as new 1s:

thereto by one of their wings, the other wings projecting outward to form flanges, 80

all as set forth hereinafter, claimed and shown in the accompanying drawing, in which:.

Figure lis a perspective view of a sluice or culvert embodying the invention; and Fig. 2 is a transverse section thereof.

Corresponding and like parts are referred to in the following description and indicated in both views of the drawings-by the same reference characters..-

The sluice, culvert or like device may be constructed of any material, metal being preferred, and is deflected between itslongitudinal edge portions into any desired form. The sections maybe of any length or width and their ends may be formed either to abut or interlock, as may be found most advantageous. The body 1 of the sluice or culvert is provided at its longitudinal edges with flanges 2. These flanges consist of angle'strips equal in length to vthe length of the culvert, each angle strip bein secured to a longitudinal edge portion 0' the culvert by one of its wings, the other wing extending-outward to form the flange. The angle strips reinforce the edge portions of the culvert, besides forming anchoring means to prevent frost lifting the culvert and supporting means to prevent the culvert from settling.

It is to be understood that the sluice is open at the bottoms and being of arch form provides ample space for the flow of water therethrough. The flanges 2 obtain an extended bearing upon the ground and prevent the sluice from settling or from being lifted by the action of frost, thereby preserving the alinement' of the sections and adding materially to the efficiency and serviceability of the structure.

Having thus described the invention, what ANDREW A. CUMMINGS. [a 5.] DANIEL s. DEMPSEY. ln. 8.]
