DITCH DAM Dimond Herschel Loosli, Idaho Falls, Idaho Application December 3, 1948, Serial No. 65,411

4 Claims.

My invention relates to the construction of ditch dams and the like, and particularly to water gate insert for a ditch dam which features extreme portability and lightness in weight, capability of being shipped through the mails, and which is produceable at extremely low cost, and an important object of my invention is to provide a simple and practical arrangement of the character indicated.

Other important objects and advantages of my invention will be apparent from reading the following description taken in connection with the drawings, wherein for purposes of illustration 1 have set forth the preferred embodiment of my invention.

In the drawings- Figure 1 is a general vertical longitudinal sectional view taken through the ground and showing an arrangement in accordance with the present invention installed therein.

Figure 2 is a top plan view of Figure 1.

Figure 3 is an enlarged perspective view of the dam per se.

Figure 4 is an enlarged transverse vertical sectional view taken approximately centrally through Figure 3.

Figure 5 is an enlarged horizontal sectional view taken approximately centrally through Figure 3.

Figure 6 is a perspective view of the gate frame.

Figure '7 is a perspective view of one of the retainer strips of the gate frame.

Figure 8 is an enlarged horizontal sectional view taken through Figure 2 approximately on line 8-8, and looking upwardly in the direction of the arrows.

Referring in detail to the drawings, the numeral 5 generally designates the ditch dam of the present invention which is adapted to be disposed at right angles to the direction of flow of water in the water passage 6 in a position declining toward the approach of the water as indicated in Figures 1 and 2 of the drawings. In accordance with the present invention a long wooden or other bar or strip i has fastened to the approach side thereof the upper edge of the canvas 8 by means of roofing nails or the like 9 which are readily applied by unskilled persons, and which by their large heads provide a good attachment of the canvas to the bar I, the bar 1 being of adequate cross section to provide the necessary rigidity and strength. The canvas sheet 8 extends substantially the length of bar 1 and has a sufficient height to have the desired reach into the ground below the ground level II]. Normall the length of the bar I and consequently the width of the canvas 8 will be greater than the width of the ditch 6 as indicated in Figure 2 of the drawings so that the bar I may rest on the opposite banks of the ditch and support the device in the desired position, with the lower end of the canvas resting on the bottom H of the ditch and the opposite ends of the canvas sheet lying along the side walls of the ditch, all as indicated in Figures 1 and 2 of the drawings.

The principal features of the present invention is the gate frame 12, shown in Figure 6, which consists of a light weight angle iron bar bent into U-shape and provided adjacent its bight with a transverse horizontal angle iron brace [3." The side flanges of the vertical legs of the gate frame which project on the water side of the device are provided with suitable holes l5 to receive roofing nails or the like 16, while the other flanges I9 are provided with holes to accommodate the bolts l5 which fasten the gate to the cross bar I. With the gate frame bolted to the bar I the canvas is laid thereon and the wooden retainer strips or cleats ll provided with openings to receive the nails [6 are laid against the canvas lying on the flange I4 with the nails I6 installed therein, and the points of the nails are then pushed through the canvas and then through the openings IS in the flanges l4, and the points of the nails then bent over as indicated by the numeral IS in Figure 5 to hold the parts assem bled. A similar arrangement with respect to a horizontal cleat l8 and the transverse brace I3 is made to hold the lower edge of the opening in the canvas. After the cleats are thus installed the canvas is cut around the inner edges of the frame so as to leave gasket forming edge portions lying respectively along the flanges l9 and the vertical flange of the cross member l3. The nails 9 similar to the nails 9 are placed close to the opening in the canvas so as to be located close to the gate frame as indicated in Figure 3 so that the canvas and the bar 1 lend support to the gate frame and a secure assembly is achieved. The vertical cleats or retainer members I! are sufflciently outwardly spaced from the transverse flanges IQ of the legs of the gate frame and the edge portion of the canvas lying thereon to provide slide spaces for the opposite lateral edges of a vertically slidable gate 20 which has on its forward face a suitable operating handle 2!. When the gate is in its lowered position with its lower end disposed between the lower cleat l8 and the vertical flanges of the cross bar 13, the upper end of the gate is flush with the top of the bar I. The gate is shown in a partially open position in Figure 3 and also in Figures 1 and 2. The cleats H, H and I8 are of suitable cross section wood or of other structurally suitable material of the same easily obtained and low cost character. The canvas between the gate 28 and the flanges '19 of the gate frame and the vertical flange of the cross member l3 act as a gasket to prevent water seeping between the opening in the canvas and the gate frame when the gate 20 is in closed position and frictionally hold the gate in adjusted positions.

3 The head of the bolts l5 are countersunk flush with the surface of the flanges IS on the gate side thereof.

The gate frame' is of a depth or height to rest its bightportion for support on the bottom of the ditch thereby more satisfactorily supporting the canvas, and preventing water from pushing the dam out of position, while holding the gate. in such a position that an even and unobstructed flow of water through the gateis arranged for, enabling accurate control of. the water discharge.

Bolted to the side members of'the gate frame at 22' below the cross member 43 and' on the opposite side of the gate frame is the wooden or other material cross bar 22 whose ends extend, slightly beyond the side edges of the gate frame. A canvas flap 23 of the width of the bar 22 is secured to said bar so as to hang down and rest on. the bottom of the ditch under the gate opening and act to prevent the water from washingaway the soil where it falls after passing through the gate opening.

.Although I have-shown and described herein av preferred embodiment of my invention, it is to -be definitely understood that I do not desire to-limit the application of my invention thereof, anyany changes or change may be made in the materials employed and in the structure and arrangement of the-parts, within the spirit of. the invention and the scope of the subjoined claims.

Having described the invention, what I claim as new is:
