Definitions

  • the present invention relates to an -apparatus for spraying insecticides, pesticides, agricultural chemicals, whitewash, paints Iand other sprayable solutions contained in a rellable tank and especially to a compression sprayer having novel sealing means for effectively sealing against leakage of air pressure generated in the tank by the intermittent operation of a pump, Iand for the positive release of entrapped air pressure when spraying has been concluded or the spray solution ybecomes exhausted and the tank requires refilling.
  • the present invention comprehends novel rneans for the positive sealing of a detachable pump assembly in a compression sprayer capable of continuously dispensing a spray solution over a substantial period o-f time by means of air pressure generated in the spray tank by the pump, and in the novel means for and manner of breaking the seal and relieving the air pressure when spraying has been completed or the spray solution has become exhausted preparatory to removing the pump Vand refilling the tank.
  • Another object of the present invention is to provide a novel resilient sealing grommet encompassing the discharge tube which passes through Ian opening in the tank and permits the passage of the spray solution from the tank and to provide a positive inner seal about 'the tube under the influence of 'air pressure in the tank.
  • This novel grommet provides a positive seal about the encompassed discharge ytube and an inner seal about the drain opening of the tank with the air pressure in the tank lifting the grommet into effective sealing contact, and when pressure in the tank is to be relieved this is easily and readily accomplished by merely pressing down on the elevated grommet to release its sealing engagement and permitting the escape of air.
  • the present invention further comprehends a sealing grommet -so constructed and designed as to be vertically movable in its mounting in the head of the tank and functioning not only as a positive seal but also as a pressure relief valve and as a means for draining the tank of its contents.
  • Another important object of the present invention is the provision of a novel self-sealing gasket encompassing an inner ange or constriction in the cupped head of the tank ⁇ defining the fill opening and having sealing contact with an external ange on the pump cylinder and also with the interior of the head 'of the tank, thereby effecting a positive inner seal.
  • the gasket is self-sealing with the air pressure in the tank enforcing its sealing effect.
  • a further object of the present invention is the provision of a novel cam-locking means for locking and sealing the pump assembly in the tank, said cam-locking means being constructed and arranged whereby the pump assembly cannot be forcibly dislodged or removed until the seal between the pump and the tank is broken and any entrapped air pressure in the tank is relieved.
  • the novel camming means on the cupped locking member or cam plate of the pump cylinder is provided with alternate vertically and circumferentially ⁇ spaced flanges having the dual 2 function of (l) locking the pump and sealing gasket in sealing contact with the .internal flange defining the fill opening of the tank, and (2) preventing removal of the pump assembly until the air pressure in the tank is relieved.
  • the present invention further comprehends the provision of a novel tank or container for the spray solution in which the head or depressed upper end of the tank completely eliminates the need of a funnel or the like for -lilling the tank.
  • the concaved head of the tank is provided with an embossment or elevated portion having a fiat surface or horizontal ledge provided with a drain opening in which is mounted the resilient grommet through which projects the discharge tube.
  • FIGURE l is a side elevational view of the novel compression sprayer but with the lower portion of the tank broken away to show the base construction.
  • FIG. 2 is an enlarged top plan view of the assembly with the spray hose and pump handle broken away as in FIG. 3, the pump assembly being in released position preparatory to removal.
  • FIG. 3 is a fragmentary vertical cross sectional view through the upper portion of the sprayer taken on the irregular line 3 3 of FIG. 2.
  • FIG. 4 is a vertical cross sectional view of the gasket shown in FIG. 3 for sealing the upper end of the pump barrel in the lill opening of the tank.
  • FIG. 5 is a yfragmentary top plan view of the pump vassembly and head of the tank shown -in FIGS. 2 and 3 but with the camming means on the pump rotated to locked and sealing engagement and with the projections ⁇ on the pump handle moved to released position permitting pumping operation.
  • FIG. 6 is another fragmentary top plan view similar to FIG. 5 but with the camming means being moved by the handle counter-clockwise toward release position in which the air pressure is relieved.
  • FIG. 7 is a top plan view of the locking clipwhich is clamped or aflixed to the head of the tank and defines its fill opening.
  • FIG. 8 is a vertical cross sectional view taken on the line 8 8 of FIG. 7 and viewed in the direction of the arrows.
  • FIG. 9 is a top plan view of the cam plate or cupped locking member which is affixed to thev upper end of the pump cylinder and forms part of the pump assembly.
  • FIG. 10l is a vertical cross sectional view taken on the line 10-10 of FIG. 9 and viewed in the direction of the arrows.
  • the novel compression sprayer comprises a tank 10 for containing a quantity of spray solution to be dispensed under pressure generated by a pump assembly 11 through a flexible -discharge tube 12 having its lower end projecting ro adjacent the bottom or 'base 13 of the tank.
