Definitions

  • the invention relates to a sprayer of the reciprocating l type, and therefore includes a relatively reciprocable cylinder and plunger pump operable to draw the liquid to be sprayed from a tank and to deliver it to Ia nozzle from which it is discharged.
  • the pump device delivers the liquid directly from the tank to the nozzle. Since the liquid itself is of course substantially incompressible, this structure required continuous manual operation of the pump as long as it was desired to continue the spraying action.
  • said reservoir being adapted to receive liquid from said pump and in which said liquid is maintained under pressure by a spring-loaded piston, the reservoir being enlarged by movement of said piston against its loading spring. Since the nozzle itself constitutes an extreme tlow restriction, rapid operation of the pump will fill the reservoir and compress the loading spring. Thereafter, spraying action will be maintained until the loading spring has fully recovered.
  • Another object is the provision in a sprayer of the class described, of a regulating andshut-off valve between the reservoir and the nozzle, whereby the rate of discharge from the reservoir may be controlled, and whereby the spraying ⁇ action may, if desired, be delayed until the reservoir is fully charged and the nozzle is properly positioned relative to the object to be sprayed.
  • Still another object is the provision of a sprayer as described wherein the nozzle is carried by an angled tube attached rigidly to the plunger of the pump, said plunger being axially rotatable relative to the cylinder of the pump, and wherein said reservoir constitutes a cylinder afxed to and extending transversely from said nozzle tube, whereby said pump and reservoir cylinders are adapted to serve as handles both for reciprocal operation of the pump and for rotation of said nozzle tube to direct the nozzle as desired.

  • Fig. 2 is an enlarged fragmentary sectional viewof the Ysprayer, showing the pump ⁇ 'section and Yrelated parts thereof, i
  • fitting is tubular, and is affixed to the screw cap 6 of a bottle or tank 8 adapted to carry the liquid to be sprayed by means of a tubular flanged nipple 10 extending through said cap and threaded into the lower portion of fitting 4.
  • a tube or hose 12 is attached to nipple 10, and depends into the bottom portion of tank 8.
  • Cap 6 is vented to the atmosphere at 14.
  • Cylinder 2 is further secured to cap 6 by means of a U-bolt 16 straddling said cylinder and secured in cap 6 as by nut i8.
  • a valve ball 20 is mounted loosely in an interior bore 22 of tting 4,Y and is retained therein by a pin 24 carried by said tting and extending transversely across said bore. Said ball cooperates with a valve seat 26 formed by bore 22 to permit ow of liquid from tank 8 to cylinder 2, but to prevent ow in a reverse direction.
  • a tubular pump plunger 28 is disposed concentrically within cylinder 2 and extends outwardly from the forward end thereof. Said plunger is of smaller diameter than cylinder 2, whereby to form an annular chamber 30 therebetween.
  • plunger 2S is provided with a tubular piston 32 sealed in cylinder 2 by a compressible O-ring 34, yand having a portion 36 of reduced diameter inserted slidably into plunger 28.
  • a valve ball 38 is carried loosely in the central bore 40 of the piston, and is retained therein by a pin 42 extending transversely across said bore. Said pin passes through both the walls of the reduced piston portion 36 and the walls of plunger 2S, so as to serve also to aix said piston to said plunger.
  • Valve ball 38 cooperates with a valve seat 44 ⁇ formed in bore 40 to permit ow of liquid from cylinder 2 into plunger 28, but to prevent llowin a reverse direction.
  • one or more holes 46 are formed inplunger 28 to communicate with the annular chamber 30 between said plunger and cylinder 2.
  • a second pin 4S is inserted transversely through the "plunger,- thelends thereof projecting into chamber 30 for a purpose which will presently appear.
  • cylinder 2 At its Vforward end, cylinder 2 has ⁇ a cylindrical tting 50 welded or otherwise aflixed thereto, and an annular bushing 52 is inserted slidably between said fitting and plunger 23. Said bushing is sealed against tting 50 by a compressible O-ring 54, and is sealed against plunger 2S by a compressible O-ring 56. The bushing is retained in place, and the 0 ⁇ rings are compressed, by a clamping ring 53 threaded on fitting S0. It will be seen that as plunger 28 is moved forwardly, ball 38 will be seated and ball 20 will be unseated, and liquid from tank 8 will be drawn upwardlyrthrough hose 12 and fittings 10 and 4 intoV cylinder 2.
  • V Y The vforward-"end of plunger ,28 "is inserted VthroughV vcylinder 69 tube maybe designatedV as a singlejtubularmemberY with f thereservoir 6 0 A interposed,intermediate the ends thereof.
