DITCH-STOP.

SPECIFICATION forming part of Letters Patent No. 674,314, dated May 14, 1901.

Application filed January 30, 1901. Serial No. 45,397. (No model.)

T0 at whom it may concern:

Be it known that I, ENOOH M. JOHNSON, a citizenofthe United States of America, residing at Beulah, in the county of Pueblo and State of Colorado, have invented certain new and useful Improvements in Ditch-Stops; and

I do declare the following to be a full, clear,

My invention relates to improvements in.

ditch stops or dams, being especially intended for use by those whose business it is to superintend the irrigation of land in sections where the rainfall is not sufficient to supply the needs of vegetation.

My object is to provide a device of this class which shall be sim ple in construction, economical in cost, and reliable, durable, and efficient in use; and to these ends theinvention consists of the features hereinafter described and claimed, all of which will be fully understood by reference to the accompanying drawings, in which is illustrated an embodiment thereof.

In the drawings, Figure l is a perspective viewillustrating the device in use. Fig. 2 is a perspective view of the device shown in detail. linesa: a; and 'yy, respectively, viewed in the direction of the arrows.

The same reference characters indicate the same parts in all the views.

Let the numerals 5 and 6, respectively, designate two blades or wings, which are pivotally connected at their lower extremities, as shown at 7. The central portions of these blades overlap each other for a distance depending upon their adjustment, as hereinafter explained. To the blade 5 is applied, near its inner edge 5 a metal strip or arm 7, which extends from the lower pivotal extremity of the blade upwardly its entire length and proj ects above the device, forming a handle 7 a to facilitate adjustment. To this handle, just above the upper edge of the blade, is attached a keeper 8, consisting of a metal piece which overlaps the blade 6 and holds the two blades Figs. 3 and 4 are sections taken on the together at the top in proper operative relation. To the upper part of the blade 6 is attached a handle 6*, provided with a keeper 9, overlapping the blade 5. As the handles are spread apart or separated the lap of the blades is increased and the width of the device diminished, while as the handles are removed toward each other the central lap is diminished and the width of the device increased. The two blades are provided at their upper and outer edges or corners with upwardly-projecting parts 5 and 6, respectively, which engage the handle-keepers and form stops limiting the outward or spreading movement of the handles.

In using the device it is placed in the ditch and the handles moved toward each other until the blades cut into the opposite sides of the ditch and form a positive stop or dam for the Water, which is thus diverted into a lateral channel, (see Fig. 1,) which figure shows a section of the ditch where myimproved device is located. The arm 7 stiffens the blade 5, and the latter forms a support for the blade 6 when the device is in use, since'the latter is so located that the arm 7 is opposite the direction of the current or the flow of the water in the ditch, and thus greatly reinforces the device. This feature also prevents the blades from spreading or bulging apart, since the weaker blade 6 is pressed by the force of the water against the blade 5, which is reinforced or stiffened by the arm 7, as aforesaid.

Having thus described my invention, What I claim is- 1. Aditch stop or dam,comprising two overlapping blades, pivotally connected at their lower extremities, and respectively provided with handles projecting above the top of the device, and a reinforcing-strip applied lengthwise to one of the blades on the opposite side from the cooperating blade.

2. A ditch stop or dam, consisting of two pivoted, overlapping blades, one of them being provided with a reinforcing-strip extending lengthwise thereof on the opposite side from the cooperating blade.

3. A ditch stop or dam comprising two pivoted overlapping blades, handles rigidly attached to the respective blades, a reinforcing-strip applied to one of the blades lengthwise and forming a continuation of its handle, and a keeper attached to the handle of each blade and arranged to overlap the upper edge of the opposite blade for the purpose set forth.

4:. A ditch stop or dam comprising two overlapping blades pivotally connected together, a reinforcing-strip attached to one blade lengthwise thereof, and extending above the blade to form an adjustinghandle, a handle attached to the opposite blade, and keepers applied to the handles of the respective blades, the keeper belonging to the handle of each blade being arranged to overlap and embrace the upper edge of the opposite blade.

5. A ditch stop or dam comprising tWo pivoted overlapping blades, a handle attached to each blade, a reinforcing-strip applied to one of the blades lengthwise and forming a continuation of its handle, and a keeper attached to each handle and overlapping the opposite blade, each blade being provided with a stop located in the path of the handle and keepers, as the handles are separated.

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

ENOOH M. JOHNSON.
