IMPROVEMENT IN FLOOD-GATES.v

The Schedule referred 4to ln these Letters Patent and making part of the same.

To all whom it may conce-rn Be it known that We, SAMUEL 4ROWLAND and Figure l is a frontview of our improved flood-gate or fence.

Figure 2 is a vertical detail section of the saine. Similar letters of reference indicate corresponding parts.

'lhis invention is an improvement on the Hood-gate patented June 17, 1862, No'. 35,591, to William'D'om` nan.

A1n his invention, the roller, in which the stakes are set, is exposed, in common with them, to the force of the flood itself', or to injury from'.contact with logs, stone, or whatever else may be carried along by the same.

` The arrangement of spring-retracting devices is also such that a box must be provided for thcir'protection, and their frequent repair aud constant care are requisite to keep his lgate in working condition.

To obviate these and other diculties connected with the practical operation of said invention, we have conceived the plan of providing an inclined frame or shed for protecting the gate on the side toward the current. We also arrange the retracting springs beneath this, and allow the stakes to rest against it when in the vertical position. Thus, no sticks, stones, or other substances can eiect a lodgment against or beneath the roller, and the gate may beleft for months without necessity of inspection occurring.

A is the under sill or fonndation-iianie of the gate or fence, which is designed to be placed upon or im bedded in the bottom` and banks of the stream, and which may be secured iii place, when necessary, by stakes or 'other means.

lhe upper side of the mnd-sill or frame A is covered with sheathing-boards B. y

O is a roller, the ends of which are pivoted to the sill or frame A, or to' supports attached to said sill or frame.

rlhe roller C may be made in one piecc,cr in sections, las may be desired, and 'to it are .attached the ends of the bars or stakes 1).v`4

E are springs, attached to the roller O, and to the silLor frame A in such a way as to hold the stakes D ina vertical position, .except when forced down by drift-wood or'other substance heilig carried down by the stream.

The springs E may be iliade of' gum elastic, or of 4some suitable metal.
