Application filed November 24, 1922, Serial No. 603,111. Renewed March 20, 1926.
The present invention relates to valves and ates and more es aeciall to irri ation A further object is the novel formationof the gate member or slide and its guide for the slidable connection thereof, and efliciently guiding said gate member or slide as well as rendering the parts strong and substantial and also as providing a tight closure of the gate member or slide.
It is also the object of the invention to provide such a device which is simple and inexpensive in construction and manufacture, as well as being thoroughly efficient and practical in use.
l/Vith the foregoing and other objects in view, which will be apparent as the description proceeds, the invention resides in the construction and arrangement of parts hereinafter described and claimed, it being understood that changes can be made within the scope of what is claimed without departing from the spirit of the invention.
The invention is illustrated in the accompanying drawing, wherein Figure 1 is a front view of the gate, showing the gate member or slide raised to open position.
Figs. 2 and 3 are sections on the respective lines 2-2 and 33 of Fig. 1, with the gate member or slide in closed position.
The present gate is adapted especially for irrigation purposes, although it can be used wherever suited, for controlling the flow of water or other liquid into and out of the end of a conduit or pipe 6. An end or guide plate 7 is secured on the end portion of the conduit, being provided with an opening 9 in which a ring 8 is fitted to slip over the end of the conduit. Said ring has an outturned flange 10 at its rear edge overlapping the rear side of the plate 7, and said ring has an inturned annular flange 11 at its forward edge extending across the edge or end of the conduit, and providing a seat for the gate member or slide, which seat is offset forwardly from the plate 7 so as to form an annular boss surrounding the opening. The conduit 6, plate 7 and ring 8 are secured together, such as by means of solder 12.
The gate member or slide 18 is movable vertically, or transversely of the conduit, across the end thereof, being made from sheet metal, as is also the plate 7 The vertical or longitudinal side edges of the slide 13 have flanges 14 extending forwardly at right angles from the slide, to stiffen or strengthen the slide against bending or warping, and the upper end of the slide has a forwardly extending flange 15, to serve as a handle for raising and lowering the slide, and to also stiffen the slide transversely thereof. The slide has a recess 16 in its lower end, and the edge portion of the slide along said recess is bent forwardly to provide an arcuate cam lip 17 which will slide over and across the upper portion of the seat or flange 11 when the slide is moved downwardly to close same, and such lip 17 also assists in stiffening the lower end portion of the slide. The slide 13 is guided by the plate 7 which is provided along its V61- tical or side edges with flanges 18 extending forwardly at right angles from the plate 7-, and the free edge portions of said flanges are bent t ward one another and rearwardly, as at 19, to abut the front side of the slide 18 between the flanges 14, with said flanges located within the bends of the flanges 18. The flanges 18 are resilient, having a tension to press the slide 13 tightly against the flange or seat 11. The slide 13 is thus guided for sliding movement across the seat 11, and the flanges 18 stiffen and reenforce the plate 7.
In forcing the slide downwardly, to close the seat, the lip 17 in contacting with the upper portion of the seat 11, will force the slide forwardly slightly, by cam action, thereby springing the flanges 18, so that the spring tension will press the slide tightly against the seat. The flange 15 in contacting with the upper ends of the flanges 18 will limit the downward movement of the slide.
Having thus described the invention, what is claimed as new is A gate comprising a ring adapted to fit over the end of a pipe and having an inturned flange at its forward edge to extend across the end of the pipe and forming a said plate having flanges at opposite sides of seat, the ring having an outtui'ned flange at said opening bent toward one another to its rear edge behind said end of the pipe, abut said slide and press the slide gainst 10 a plate behind the firstnamed flange and said seat.
5 having an opening, the outturned flange be- In testimony whereof I have signed iny ing secured to said plate around said openname to this specification. ing, and a slide movable across said seat, JOHN B. KINGHAM.
