  • This leaf spring extends outwardly to a position benea-.h the leg 33 and bears upwardly against the land 52 when the flapper is in the horizontal position or attitude, and against the foot 51 when the flapper is in the vertical position, exerting a holding pressure against said land or foot, as the case may be, which must be overcome to change the attitude of the flapper.
  • This pressure is normally sufficient to prevent the llappers from changing positions except when urged by force sufficient to overcome the pressure of the spring 53, and thus the ilappers will ordinarily remain in the assumed attitude under normal conditions.
  • the flapper base ear 28 has a rearwardly extending upper bracket 55 and a rearwardly extending lower bracket 56 spaced vertically from said upper bracket.
  • Each of said brackets has a hole vertically therethrough and aligned with the hole in the other bracket, in which is mounted a plunger 57, on the upper end of which is a laterally extending plunger handle 58 which may be threaded into the plunger 57 after the latter is mounted in the brackets 55 and 56.
  • Plunger 57 on its lower end and extending upwardly-for example, about a third of the length of the plunger-is preferably increased in diameter to form a strike or stop member 59, the increased diameter strengthening the plunger and also forming a shoulder on the top of the strike portion 59.
  • the bracket 55 has an upwardly extending boss 61 which is grooved laterally on its upper surface, as indicated at 62, with a groove to receive the handle 58.
  • the upper bracket 55 is likewise grooved, as shown at 63, on its upper surface for the purpose also of receiving the handle 58.

  • Lifting the lever handle 72 rotates the arm 73 clockwise and moves the latch hook 7.4 from beneath the slider bracket hook 85, freeing the latch and mechanismy so that the flappers may be raised to the vertical position.
  • the pivotal or clockwise movement of the arm 73 is limited by the stop 78 on the lever extension 75 striking the stop boss 79, so that this movement need be sufficient only to clear the latch hook 74 from engagement position with the slider bracket hook 85 to release the mechanism.
  • the stop 86 on the slider bracket is preferably slanted, as indicated for example in FIG. 2, so that when the flapper 32 is moved to the horizontal position, the outer end of the latch hook 74 will ramp or slide down the surface of the stop 86 and move under the slider bracket hook 85 automatically. The force of the spring 81 on the lever extension will urge the latch hook 74 to move counterclockwise, causing such automatic locking.
  • the slider bracket ⁇ 84 has been drilled lengthwise to provide a hole 87 for the receipt of a swivel lock plunger 88.
  • the top portion of the slider bracket is provided a groove from the hole 87 connecting with an outer slot 89 and an inner slot 91, as best Iapparent from FIGS.
