HEAD-GATE.

To all whom it may concern:

Be it known that We, JOHN Z. HANSON and WVILLIAM D. THOMAS, citizens of the United States, and residents of Aberdeen, in the county of Bingham and State of Idaho, have invented a new and Improved Head-Grate, of which the following is a full, clear, and exact description.

Our invention is capable of embodiment either in a permanent head gate, or in a portable head gate adapted to be located at any point in aditch, to raise water therein where desired.

It is an object of the invention to provide an improved valve means for commanding the opening in the gate, and a novel arrangement of manually-controlled operating rod and guide therefor.

The invention will be particularly explained in the specific description hereinafter to be given.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a front elevation of a head gate embodying our invention, showing the same in position for use; Fig. 2 is a sectional plan view; and Fig. 8 is a side elevation with parts broken away.

In forming a head gate in accordance with our invention, the body 10 of the gate is preferably formed of a plate and is of a size to range across a ditch, as indicated by the letter A, to regulate the height of the water B at the front of the gate. Said gate is provided with a suitable opening for the water, and surrounding said opening is an annular flange 11, that extends forwardly. If the gate is employed in the head ditch in a permanent position, it may have a rear flange 11 to receive any suitable lateral pipe (not shown) to extend through the bank of the ditch.

The opening through the gate is commanded by a valve disk 12, having a peripheral ear 12 which is pivoted on a post 13 that extends forwardly from the gate 10 parallel with the flange 11 and outwardly beyond the latter. The valve can be swung on" its pivot by means of a manually-controlled operating rod 14, which is pivoted at Specification of Letters Patent.

Application filed March 12, 1913.

Patented Dec. 30, 1913. Serial No. 753,730.

14, to a peripheral ear 12 on the valve disk, said rod extending upwardly in front of the gate, above the top thereof, and having guided movement in a horizontal keeper bar 15 which is connected-by the legs 15 with the gate 10. The operating rod 14 is provided with a suitable handle, preferably by forming a rearwardly extending arm 14 thereon at the outer end, which is disposed above a horizontal, forwardly extending flange 1O on the top of the gate. The flange 10 constitutes a handle or gripping member to be utilized in placing and removing the gate.

The valve disk 12 is pivoted to the rod 14 in a position to bear against the outer edge of the forwardly extending flange 11, the pivot ear 12 of the valve being disposed at the inner side of a fixed member 16 preferably in the form of a disk or collar on the post 13, to bear against the said inner side of the member 16. A retractile, helical spring 17 is secured at one end to the valve disk 12 adjacent to the collar 16, and the opposite end of the spring is secured to a presser bar 18 pivotally mounted 011 the post 13, at the outer end of the latter, said presser bar extending in the direction of the valve disk and terminating in a foot 18 which is parallel with and has a bearing on the outer face of the valve disk. The foot 18 is free to slide relatively to the valve disk 12 within a keeper 19 on said disk.

It will be observed that the spring is connected with the presser bar 18 at a point farther from the pivot post 18 than the connection of the spring with the valve disk, so that the force of the spring will act on the presser bar through a longer lever arm than in its action on the valve disk, so that the increased leverage causes the force of the spring to be greater on the presser bar than on the disk, the result of which is that the spring acting through the presser bar will tend to hold the valve tightly against its seat on the flange 11 in any position to which the valve has been moved by the operating rod 14.

To facilitate the placing of the gate in position, its bottom edge is convexed and formed with teeth 20, giving the said bottom edge the form of a saw. By means of the bottom 'saw edge and the handle portion 10, the gate may be caused to readily cut its way into the ground when placing the gate in position.

Having thus described our invention, We claim as new, and desire to secure by Letters Patent:

1. A head gate having an opening, an annular flange on the gate at the opening, a pivot post on the gate extending forwardly beyond the flange and having a fixed bearing member adjacent to the outer end of the flange, a valve disk having a peripheral ear pivoted on the post adjacent to the inner side of the said fixed member, to bear against the latter, the valve being adapted to be swung across the opening in the gate close to the annular flange, a manually-controlled operating rod pivotally connected with the valve disk and having guided movement on the gate, a presser bar pivoted on the post at a point outward from the valve disk and mentioned fixed member, and extending to the said valve disk, the outer end of the presser bar having a foot parallel with the valve disk and bearing thereon, a keeper on the valve disk beneath which the foot of the presser bar has sliding movement on the valve disk, and a helical retractile vspring secured at its ends to the valve disk andpresser bar respectively, the point of connection between the spring and presser bar being farther from the pivot post than the connection of the spring with the valve disk.

2. A head gate having an opening, an annular fiange on the gate at the opening, a post on the gate extending forwardly beyond the flange and having a fixed bearing member, a valve disk pivoted on the post and lying beneath the inner surface of the fixed member, to bear against the latter, a presser bar pivoted on the post, and a retractile spring connected at one end with a valve disk and connected at its opposite end with the presser bar at a pointfarther from the pivot than the connection of the spring with the valve disk.

In testimony whereof we have signed our names to this specification in the presence of two subscribing Witnesses.
