FLOOD-GATE.

SPECIFICATION forming parter- Letters Patent No. 791,637, dated June e, 1905. Applicationrled September 26, 1904. Serial No. 226,066.

To (LM whom it may concern..- n

Be it known that I, HENRY DEARBORN MER- RILL, a citizen of the United States, residing..

This inventionrelates to automaticrHood fences or gates for luse across streams and low places liabie to be Hooded in certain seasons of the year, which will effectually prevent the passage ofl stockduring the dry season, but which will yield and permit the passage of drift material during high water or Hoods without damage and be restored to its former position when the Hood has passed.

The invention has for its lobject to improve and strengthen the construction of devices of this character. A y

With these and other objects in view, which will appear as the nature of the invention is better understood, the same consists in certain novel features of construction, as hereinafter fully described and claimed.

In the accompanying drawings, forminga part of this specification, and in which corresponding parts are denoted by like designating characters, is illustrated the preferred form of embodiment of the invention capable of carrying the same into practical operation,

In the drawings thus employed, Figure 1 is an elevation of the improved device from the downstream side. Fig. 2 is a plan view of the same. Fig. 3 is a section on the line 3 3 of Figi l. Fig.L 4 Ais a section on the line 4 4 of Fig. 1. Figs. 5 and 6 are enlarged detail be any distance apart, according to the nature of the ground.` Where the stream or low land is relatively contracted, one of the gates only willgenerallybe' required; but for wider streams -orlands two or more of thefgates may be employed and arrangedto operate independently. For the purpose of illustration two of the gates are shown, with anintermediate su ppor'ting-post 12. The ordinary fences 13 14, of any approved construction,

will/lead from the boundary-posts 10 11.

The automatic gate or fence'portion of the Y-device consists of the head member-l5, having spaced pickets 16 and provided at the ends with U-shaped loop-bolts 17, connected to the inner faces of the posts 10 11 and both sides of the intermediate post 12 by bolts 18. The ends of the head members 15 extend past the upstream sides of the posts and are preferably squared ,where they engage the posts and hang from their pivot-bolts at an angle, as

shown more clearly in Fig. 5, and thus support the pickets 16 normally in a vertical position. The-outer ends of the pivot-bolts 18 vare supported by guard-straps 19, bolted to form a water-shedding surface and preventing damage to the banks by drift material and ice.

The intermediate post 12 is provided with a U-shaped strap 32, extending above the same and between whose sides the central pivot-bolt .18. is connected, the strap thus performing substantially the same function as the guardstraps`19 and being, in fact, a modified form of' the same. The U -shaped strap 32 also serves as a support for one end of an inclined combined ice-breaker and post-supporter 33,

the member 33 being supported and 'strengthened by a mudsill 34 and vertical stay members 35 in substantially the same manner as the members 20 21 are 'strengthened and supported.

The'construction is very strong and durable "Ioo The U-shaped straps may also be employed,H

upon the end posts if required.

Having thus described the invention, what is claimed is- 1. In a flood-gate, spaced supporting-posts at the sides ofthe gateway-opening and one or v lmore intermediate supportingfposts, U-shaped keeper-straps connected to said intermediate y, posts and provided with transverse pins, gates formed of head members-and spaced pickets with the adjacent ends of the `head members f `provided vvitlrelongated eyes for-movably engaging -said pins betweenzthe sides ofisaid U-shaped straptrand a guard member connected to each of saidl strapsfat the upper terminal Iof the same and extendingat an incline therefrom and secured to the bed of the stream at the .upstream side of the gate.

2.i In a flood-gate, spaced supporting-posts at the sides of the gateway-opening and one or more intermediate supporting-posts, keeperstraps on the inner sides of the end posts and upon both sidesof the intermediate posts and spaced therefrom and provided with transverse pins, and gates formed of head meinbers and spaced pickets and provided with elongated eyes movably engaging said pins.

3. In a Hood-gate, a supporting-post having an inverted-U-shapedstrap attached to its sides and -provided with a transverse pin, in

elongated eyes for movably engaging said transverse pin.

In 'testimony that I claim the foregoing as i my own I have hereto aiiixed my signature in the presence of two witnesses.
