To whomvit may concern The nat-ure of this invention relates to an improvedconstruction-of Hood-gates, and consists in the peculiar construction of the gate and its frame, the former being sectional, and the latter hinged to the crossbeam, and the whole so arranged that, in h igh water a single section, or as many `more as may be neces'- sary, will lift to permit the passage of oating sticks and other obstructions;

Awhole may be swung up clear of the water, so as not to be frozen in, which would render itliable to be carried away when the ice broke up. 1n the drawing, which isa perspective view of the down-stream side of my `fiood-gate- A represents mud-siils, secured in the bottom of brook, near its sides, on which are erected the posts B,

connected at theftop by across-beam, O..

D is the gate-frame, composed of two verticalv 'pieces of timber connected at the top by a cross-beam;

from the upper corner of the downstream side of -the beam C project the' pintles d, to which the gate-frame is ypivoted by an iron rod, b, passing through all.

E are the sections of the gate, in the shape of planks, either hinged to the bar b or bored transversely through their upper ends, so that the bar may pass through them in the manner shown.

useful Improvement ina" in low water the sections are secured to the frame, and, `on approach of winter, the

D' are side bars, one of which issecuredon the down-stream facevof each of the vertical bars of the gate-frame.

AF is a transverse bar moving np and down in thc slide-bars.

c are pins passing through the braces of thegposts B, and, engaging with the gate-frame, secure the lat- 1er in its vert-ical position; in the latter position, .and in low water, the bar F is moved down to thebottom of the slides, when the gate sections and frame' forin essentially a'solid strluiture; during high water or flood, thebar F is raised upA in the slides above the tops of the sections., which give readily to a oating ohstruction'and permit it to pass. On the approach ot' frost-y weather, the bar F- 'is moved. up above the sections andthe pins c withdrawn from the gateframe, which is swung up ou'its pivot to a horizontal position, resting on the cross-beam C, as sh'own by the dotted lines, while the sections are/thrown up to rest 'on the cross-bar at the top of the frame, as shown in like inan'n cr;by this means, the gate will not'be frozen in during the winter, to be carried away when the ice breaks up in the spring.

That Iclaim as my invention, and desire to secure byLetters Patent, is

The construction and arrangement of the sills A, posts B, cross-beam C, and gate-trame D, pivoted thereto by the bar b, said bar having also pivoted on it the' sections E, the slides D', and bar F,`as and for the purpose set forth.
