To 3 whom, it may concern:

Be itlmown that I, LITTLETON W. TRAVIS,

a citizen of the .United States, residing at .Martin,in the county of Weakly and State of 5 Tennessee, have invented new and useful Im rovements in Flood-Gates, of which the folowingis a specification.

This invention relates to flood-gates designed especially for use in ponnection with irrigation-canals and other waterways, and

has for its objects to produce a comparatively simple inex ensivedevice of this character which may e readily installed foruse,

. wa but will automatically open under the uen'ce of an abnormal water-pressure, and

one wherein' the gate-supports will efl'ectually withstand an abnormal flow-of water .20 to obviate injury thereby to the gate.

, With'these and other objects in View the invention comprises the novel features of construction and combination of parts more fully hereinafter described.

z 5 In the accompanying'drawings, Figure'l is -a front elevation of a gate embodying the invention. Fig'."2 is a to plan view of the same. Fig. 3 is an all arged detail view,

partly in section, showing the mannerof'cono necting'the the posts. F1g.- 4 is a front elevation showing a modified embodiment ofthe invention. Fi 5 is a top'plan view-of the same.

- eferring to the drawings, 1 designates an I3 5 irri ation-canal or other waterway in-which is p anted apair of vertical posts or standards 2, disposed, res .ectively, at opposite sides of the canal and avin their upper ends connectedby a horizonta bracing rod or element 40 3, said posts being further braced by means of diagonal guides i attached at their upper ends, respectively, to the posts and at their lower ends to anchors v5, embedded'in'the ground at o positesides of and suitably re 4 5 mote from t e canal 1 Sustained by the posts 2 is a gate 6, comprising two sets or series of members or sec tions 7 8, pivoted, respectively, to the posts 2, it being'noted in this connection that the members or sections comprised in each set are spaced relatively in vertical planes and that the sections 7 are arranged inalternate staggered relation relative to the sections 8,

whereby the outer or free ends of the-sections 5 5 may normally overlap in superposed osition. The members or sections of eac segate members or sections with rice are connected to their appropriate post 2 by a single connecting and pivoting element or wire .9, threaded through perforations 10, formed at the inner ends, ofthe sections, be-

tween which latter the element 9 is folded or crimped, as at 11, and secured to the post by fastening members or staples 12, thus pro- 100 s adapted to receive separately the severa sections of theseries.

In practice the gate normally stands in closed position, with the outer or free end of the sections 7 8 disposed in overlapping suone whereby a normal water-level. will be I .15 properly maintained-in the canal or water perposed relation, as illustrated, whereby the weight of the sections. bearing one upon another serves to maintain them in normal ducing in the element separate portions or position for withstanding the usual pressure p of the water containedin the canal or waterway 1, it being noted in this connection that owing to the gate members or sections being spaced vertically'a sufficiently free passage of the water through the gate is permitted, while at the same time the gate offers sufficient resistance to maintain the proper waterlevel in the canal. When, however, the gate is subjected-j-to an abnormal water-pressure resulting from a flood or ireshet, the sections 7 8 will yield readily to the increased pressure and be swung to open position, as indicated by dotted lines in Fig. 2, thereby permitting the water to flow freely and unobstructedly in the canal and relieving the conjested con-' dition of the latter, it being understood that when the water again reaches its normal level the gate is manually closed by arranging the sections 7 and 8 in the manner heretofore explained. It is to be particularly observed that under this construction of ate and owing to' the sections opening frer y under an abnormal pressure liability of the gate being injured or other damage ensuing from a swollen condition of the water in the way is whollyobviated. Itis also to be observed except that -I- have shown a. double gate adapted for use in connectionwith a canal or waterway 1 of unusual width and which necessitates the planting of an intermediate. post 2 at the transverse center of the-waterway for service in conjunction with the posts for the attainment of the 2 for proper hanging or mounting of the pair of gates 6, the members or sections 7 8 of which are, however, disposed in relative arrangemente and connected with the posts in the-manner above described.

From the'foregoing it is apparent that I produce asimple device admirably adapted ends in view, it being understood that in attaining these ends minor changes-in the details herein set forth may be resorted to without departing from the spirit of the invention.

Having thus fully described my invention, what I claim as new is- In a gate of. the type described, a pair of posts or standards, two sets of cooperating gate members arranged in vertically-spaced ally connecting the erases relation and in relative staggered order, said sets of members being adapted for arrangement with their outer ends in overlapping superposed condition, and means for pivotsets of members with their respective posts, said pivoting means comprising an element threaded through the set of sections, and fastening members for attaching theelement to the post at points between the sections.

In testimony whereof I affix my signature in presence of two Witnesses.

I LITTLETON W. TRAVIS.
