JACOB A.'DUNI-IAM, OF ROLL, INDIANA.

FLOOD-GATE.

SPECIFICATION forming part of Letters Patent No. 425,869, dated April 15 1890.

Application filed January 29, 1890- Serial No. 338,444. (No model.) 7

To all whom it may concern:

Be it known that I, JACOB A. DUNHAM, a citizen of the United States, residing at Roll, in the county of Blackford and State of Indiana, have invented certain new and useful Improvements in Flood-Gates; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which'it appertains to make and use the same.

This invention has relation to an improvement in flood-gates, and the novelty will be fully understood from the following description and claims, when taken in connection with the annexed drawings, in which- I Figure 1 is a perspective view of a floodgate constructed according to my invention. Fig. 2 is an end view of the same'with the gate in an erect position. Fig. 3 is a perspective view of a modification of the gate-post such as used in arock bed, and Fig. t is a View of one end of the log.

Referring by letter to the said drawings, A indicates posts, there being two arranged at opposite points on the opposite sides of a stream, as shown. These posts may be of wood or other suitable material, and are provided on their upstream sides and inner sides, respectively, with staples a and b, for a purpose which will be presently explained.

13 indicates the log. This log is designed to extend the width of the stream and from one post to the other. Said log is recessed or cut away on its inner side or downstream side at opposite ends, as shown at 0, Where it normally bears against the upstream side of the posts A.

D indicates a chain, there being two employed-one at each end of the log. These chains are secured at their lower end to the lower portion of the log and in the plane or recessed portions thereof, the opposite ends of said chains being secured to the staples a in the posts, which are arranged in the up stream side thereof and at a suitable point above the log.

E indicates chains, which are secured at one end at a suitable point to the inner sides of the posts, and at their opposite ends to the log in advance of its vertical center or slightly to the upstream side thereof. These chains E serve to sustain the pickets in an approximately horizontal position, while the chains D serve to sustain the log and pickets carried thereby in proper position after a flood.

As it is sometimes necessary to set the posts in av rock bed, I have provided the posts shown in Fig. 3 for the purpose. This post, instead of being made of wood, is made of metal or like material, and is provided on one of its longitudinal sides with notches, so as to present barbs cl, whereby it may enter the rock, as shown in Fig. 3.

In setting the metal post- I employ a wedge, such as F, which is driven down one side of the post, so as to force-the notches therein forcibly into the rock or rocks. This metal post is also provided with a yoke G for the attachment of the chains D and a yoke H for the attachment of the chains E.

When the stream is very wide, I arrange a third post in the center of the stream, and form the fence or gate into two-panels instead of one, the logs beinghung at one end to said center post.

Having described my invention, what I claim is* 1. In a flood-gate, the combination, with the posts on opposite sides of the stream, of the log 13, having its opposite end. recessed at c and carrying pickets, the chains D, secured at one end to the lower portion of the log and in the recesses thereof and at their opposite ends secured to the upstream side of the posts, and the chains E, secured at one end to the inner sides of the posts and at their opposite ends to the log in advance of its vertical center and slightly to the upstream side thereof, substantially as specified.

2. In a flood-gate, substantially as described, the combination, with the log carrying pickets and chains suspending the same, of the posts having notches on one side, a wedge for locking the post in its seat, and the yokes for the attachment of the log-chains, substantially as specified.

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