Specification of I zetters Patent. Pgfliented Oct, 4, 1921,

Application filed April 16, 1921. Serial No. 462,059.

To all whom it may concern 1 Be it known that I, ONESIME J. HALLEE, a citizen of-Canada, residing at Chisholm, in the county of Franklin and State of Maine, have invented certainnew anduseful Improvements in Dam Constructions, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to improvements in dam constructions and more particularly to a construction of the flood gate type.

An important object of the invention is to provide a construction of this character wherein when the automatic flood gate is moved to the discharge position all of the water passing through the gate will pass over the same so as to prevent the collection of debris at the base of the gate, preventing proper closing of the same.

A further object of the invention is to provide a novel construction offlood gate which may be readily placed upon a stream bed without necessitating the construction of an expensive and costly base therefor.

Other objects and advantages of the invention will become apparent throughout the course of the following description.

In the accompanying drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention and wherein like reference characters designate like parts throughout:

Figure 1 is a fragmentary perspective of a flood gate constructed in accordance with my invention.

Fig. 2 is a side elevation thereof, and

Fig. 3 is a section on the lines 33 of Fig. 2.

Referring now more particularly to the drawings, the numeral 10 indicates a substantially vertical wall formed upon a bracket 11 and connecting at its upper endwith a wall 12, inclining upwardly from the upper end of the vertical wall 10 and extending in what might be termed a downstream direction therefrom.

At the junction of the vertical and inclined walls 10 and 12, a socket 13 is formed,

for the reception of a shaft 14 the shaft beingheld in position in the socket by means of straps 14 bolted through the vertical and inclined walls or some similar expedient. For each flood gate section a pair of the brackets 11 are provided.

The numeral 15 indicates a flood gate formed of vertical strips suitably braced passage of the water thereover.

as at 16, and pivotally connected to the shaft 14 by means of bearings .17 secured to the flood gate 15 and through which the shaft 14 extends. Attention is directed to thefact that the mounting of the shaft 14 in the sockets. l3 permits of the engagement of the face of the flood gate flatly with the walls of the vertical and inclined sections 10 and 12, these sections being notched, as at 10 and 12 to accomodate the braces 16. The brace 11 will be sufficiently widely spaced so that the flood gate 15, pivoted therebetween, will cover approximately half 7 of the wall of the braces with which it coacts, thereby permitting of the arrangement of a plurality of flood gates in series as shown in Fig. 8, without forming between the flood gates a space necessitating the rovision of a vertical stop wall to prevent ow. The lowerends of the vertical walls 10 of the adjacent brackets 11 are connected by braces 18, and the upper ends of the inclined walls 12 thereof are connected by braces 19 which receive and support the upper and lower edges respectively of the flood gate 15 so that when the same moves to either open or closed position it is supported by both the shaft 14 and a brace 18 or 19, rendering the same very solid.

The operation of the flood gate is identi the gate remaining in the position shown in Fig. 2 until the water reaches a predetermined height when it automatically swings to the position shown in Fig. 1, permitting In order to prevent the collection of debris at the base of the flood gate in such a manner as to prevent proper closing of the same, I provide in advance of the flood gate a baflie grid 20 formed of spaced strips 20*, suitably braced as at 21, with which the gate 15 coacts when in the open position as indicated in Fig. 1, to bar the passage of debris be-- neath the gate.

The construction hereinbefore set forth being capable of many changes and variations with respect to size, shape and arrangement of the various parts hereinbefore set forth without in any manner departing from the spirit of my invention, I do not limit myself to the specific structure thereof except as hereinafter claimed.

What I claim is:

1. An automatic flood gate comprising a. pair of spaced supports, each embodying a substantially vertical Wall and a wall connected to and inclining upwardly from the same, a brace connecting the vertical walls of said supports at the lower ends thereof,

a second brace connecting said inclined walls at the upper ends thereof, a pivot member secured at its ends to'said supports at the juncture of the vertical and inclined walls thereof, and a flash board pivotally mounted upon said member and swinging to alternately engage said braces. r

2. The combination with a normally vertical horizontally pivoted flood gate adapted to automatically shift upon the pivot thereof a to open positionto permit passage of the water retained thereby when the same has attained a predetermined depth, of means coacting with the lower end of the flood gate for preventing the passage of debris therebeneath while in such open position.

3. The combination with a normally vertical horizontally pivoted flood gate adapted to automatically shiftjupon the pivot thereof to open position to permit passage of the water retained thereby when the same has attained a predetermined depth, of an inclined baflie grld'arranged adjacentsaid flood gate and coacting with the lower end thereof to prevent'tlie passage of debris therebeneath when the gate is in open position.

In "testimony whereof I hereunto aflix my signature.

ONE SIME J HALLEE.
