Definitions

  • apron is made as a separate unit and fixed to the frame by a U-link which is secured to a frame beam by a crosspiece fixedly connected to the upper end of the apron, and by an inverted U-link which is secured to a spaced portion of the frame beam by a second cross piece fixedly connected to gussets forming part of the apron. Stops are provided to fix the position of the inverted U-link on the frame beam, and shims are utilized with the second crosspiece to effect precise adjustment of the centering of the apron on the axis of rotation of the gate.
  • This invention relates to gates for automatically controlling the flow of water in canals, streams, etc., and more particularly to an improved apron construction for the sector type of such automatic gates.
  • Automatic gates of the sector type are usually constituted of an upstream, arcuately-shapedgate apron centered on the axis of rotation of the gate, a downstream sector-shaped, gate float centered onthe same axis, a frame connecting the gateapron and the float, and ballasting means for balancing the gate to effect its automatic operation.
  • the frame 3 is composed of two parallelly disposed hollow'metal frame arms 3',3" of rectangular 0 configuration.
  • the upper portionsof the outer ends of the arms 3,3" are cut out, leaving the lower portions thereof to provide reduced sections 13.
  • the top of each reduced section 13 and the end of the upper portion of the frame arm from which such reduced section proarms of the frame'in an exactly centered position relajects, are closed by an angle plate 22 to prevent the tive to the axis of rotation of the gate.
  • the aforesaid purpose is attained by constructing the apron as a separate 7 unit and then fixing the apron to the frame by means that include a U-link which is secured to a reduced section of a frame beam by a crosspiece fixedly connected to the upper end of the apron, and an inverted U-link which is secured in position on a spaced section of the frame beam by a second crosspiece fixedly connected to gussets forming part of the apron. Stops are provided to fix the position of the inverted U-link on the frame beam, and shims are utilized with the second crosspiece to effect precise adjustment of the centering of the apron on the axis of rotation of the gate.
  • FIG.-l is a schematic, side elevational view of the gate
  • FIG. 2 is an'enlarged, side elevational view of the gate apron with one of the outer gussets partly broke away to show the outer U-link assembly more clearly;
  • FIG. 3 is a top plan view of the parts shown in FIG. 2;
  • FIG. 4 is a sectional view taken along the line 4-4 in FIG. 2;
  • FIG. 5 is a sectional view taken along the line 55 in FIG. 2.
  • the automatic gate shown includes a frame 3 which extends upstream from the gate pivotal axis 2 and on the outer upstream end of which is mounted a sector-shaped apron 1 radially disposed to the pivotal axis 2.
  • the gate unit further includes a hollow sector float 4 which is also centered for pivotal movement about the axis 2 and which moves in a tank 5 that is in communication with the downstream reach of the canal.
  • the float 4 also functions as a ballasting container for ballast material 20 which is loaded therein when the gate is in its closed entry of moisture into the frame arm.
  • each crosspiece 17 may also be connected, as by welding, to the opposed faces of an outer gussett 11 and an inner gusset 12 associated in spaced relation with each frame arm and secured along their outer end edges, as by welding, to the interior surface of the apron 1.
  • the crosspiece 17 forms part of one of the devices for securing the apron 1 to the frame arms 3,3"
  • the link 8 is secured in position by two lock nuts 25 in threaded engagement with the legs 24 thereof and tightened against flanged lock washers 26 seated on the upper surface of the crosspiece l7.
  • the other assemblies or devices for securing the apron 1 to the frame arms 3'3" each include a stop 10 which is permanently secured, as by welding, to the lower surface of the associated frame arm so that the outer end face 30 thereof is spaced a given distance from the pivotal axis 2 and a given distance from the centerlines of the holes 23 in the associated crosspiece 17.
  • a second stop 14 Permanently secured to such lower surface of the associated frame arm in spaced relation to the end face 36 ⁇ of stop 10 is a second stop 14.
  • Located between the two stops 10 and 14 is a crosspiece 9 which is seated against the end face 30 of stop 10 so that it is precisely positioned with respect to the axis 2.
  • the crosspiece 9 extends across and is permanently secured, as by welding, to the inner end edges of the spaced gussets 11 and 12 associated with this assembly. It will thus be seen that each pair of gussets 11 and 12 are rigidly secured in proper fixed relation by the connections of their inner end edges with the crosspiece 9, of their front end edges with the interior surface of the apron 1, and of their opposed surfaces with the ends of the crosspiece l7.
  • the crosspiece 9 is provided with two spaced openings 31, in FIGS. 2 and 4,-through which are inserted the threaded ends of the legs 32,32 of an inverted U-shaped link 7 straddling the associated frame arm so that its central portion bears on the upper surface of such frame arm.
  • the link 7 is secured in position on the frame arm by lock nuts 15 that are screwed on the threaded ends of the link legs 32 into tight engagement with the flanged lock washers 33 seated on the lower surface of crosspiece 9.
  • the apron l Prior to the tightening of nuts 15, the apron l is precisely centered with relation to the axis of rotation 2 by inserting one or more shims 18 between the crosspiece 9 and the lower surface of the associated frame arm.
  • a sector-shaped apron 1 of a given curvature can be exactly centered on the axis of rotation 2 by a securing means which precisely positions the apron 1 at the correct radial distance for its given curvature from such rotational axis and precisely arranges such apron with respect to such axis so that all of the radii extending from such axis to the apron will be exactlythe same length throughout the extent of its sector shape.
  • stops 10 serve. a dual purpose; (1) they help to position accurately the apron on the frame arms, and (2) they support the thrust of the apron along the axial lines of the frame arms 3' and 3".
  • a water gate including a frame, means on said frame for mounting the gate for pivotal movement about a fixed axis, a separate, removable, sectorshaped gate apron of given curvature, and means supporting said apron on said frame so that it is centered with respect to said axis, said supporting means comprising a first means fixed to said frame and a second means fixed to said apron and cooperative with said first means to position the apron relative to said frame so that the distance of said apron from said fixed axis is comparable to the length of a radius from said axis of the curvature of said apron and so that the plane of ourvature of the apron is parallel to said fixed axis, first connecting means for securing said'first and second means in cooperative relation and said apron to said frame, a third means fixed to said frame spaced substantially from said first connecting means and located adjacently said apron and a fourth means fixed to said apron and cooperative with said third means to center the said a
