Definitions

  • a piston pump spray gun with a detachable container for fluids, such as paint, to be sprayed is provided with a removable di cast metal or injection molded plastics one-piece pump housing and lid or cover for the container with the pump housing portion molded or cast around a hard metal cylinder sleeve for the piston and passages connecting the interior of the sleeve with the container without requiring seals to feed liquid from the container to the pump and for draining liquid back to the container.
  • the one-piece part together with a piston operating in the cylinder sleeve is easily mounted on and removed from the main body of the spray gun by means of a single securing ring rotatable on the pump housing portion and threaded in the front of the main body of the gun.
  • the one-piece molding or casting with it's integrated hard metal cylinder eliminates leakage paths, reduces manufacturing costs, and facilitates replacement or repair of worn or broken parts.
  • the one-piece part of this invention provides a pump housing portion molded or cast around a cylinder sleeve in which the piston operates and a depending cover or lid portion into which is threaded a container for material to be sprayed and having leak proof passages conveying fluid between the container and sleeve without the aid of seals.
  • the piston housing portion of the part carries a locking ring which is threaded into the spray gun housing for securing the part to the spray gun.
  • Prior Art Piston pump paint spray guns have heretofore been provided with piston cylinders or sleeves inserted in a bore or recess in the spray gun housing and secured therein by a threaded pin.
  • Such constructions required seals between the cylinder sleeve, the bore in which the sleeve was received, and the structural part providing the bore. These seals had to be seated in recesses and not only were extra seal parts required, but additional machining was necessary. Then when the cylinder sleeve was replaced, satisfactory rescaling was frequently not obtained so that air would be sucked into the piston pump and feed performance would be impaired.
  • the present invention now eliminates the heretofore required seals and extra machining operations for piston pump spray guns by molding or die casting the pump housing around the cylinder sleeve for the piston and integrating this housing with a depending lid or cover for the spray gun supply container.
  • the onepiece pump housing and lid molded or cast part has a hollow stem receiving a suction tube depending into the container which registers with an aperture in the cylinder sleeve to feed the liquid to be sprayed to the pump and also has a passageway communicating with a chamber in the sleeve to drain liquid back to the container. Machining of the passages and seals between these passages and the cylinder sleeve are not needed because the pump housing part is tightly molded around and integrated with the cylinder sleeve.
  • the one-piece molded or die cast part is detachably mounted on the main housing of the spray gun with the pump housing portion of the part having a cylindrical sleeve fitting into a bore of the gun housing and the lid portion of the part underlying the housing while a neck connecting the pump housing and lid portions of the part fits in an open front recess in the bottom of the housing bore.
  • a single locking ring on the pump housing portion is threaded into the bore of the gun housing to secure the part in position in the gun housing.
  • a spray head is threaded on the outer end of the pump housing portion of the part and an outlet valve slidable in the pump housing portion seats against an end of the cylinder sleeve while a piston slidable in the sleeve is reciprocated by driving means in the gun housing to suck liquid from the container into the cylinder sleeve and to discharge the liquid from the sleeve through the outlet valve to the spray nozzle.
  • Another object of the invention is to eliminate heretofore required seals between the pump housing and cylinder sleeve of a piston pump spray gun.
  • Another object of the invention is to provide a spray gun with a removable molded or die cast part housing a piston pump assembly and suspending a supply container from the gun.
  • a further object of the invention is to provide a spray gun for the atomization of liquids by means of a piston pump driven from an alternating current oscillating magnet and having a supply container suspended therefrom wherein a one-piece molded or cast part provides the pump housing and the lid for the supply container and is removable from the gun by manipulation of a single locking member.
  • Another object of the invention is to provide a piston pump spray gun having a housing with an open front bore and an open front bottom recess detachably receiving a one-piece part including a pump housing fitting said bore, a neck fitting said recess, and a lid suspended from said neck underlying the gun housing to support and close the top of a supply container.
  • FIG. 1 is a side elevational view of a spray gun provided with the pump part of this invention and shown partly in vertical section;
  • FIG. 2 is an enlarged vertical sectional view of the pump and container lid part provided for the spray gun of FIG. 1 according to this invention.
  • FIG. 3 is a front end elevational view with parts in transverse section of the spray gun of FIG. I.
  • the spray gun I of FIG. 1 is especially suitable for paint spraying and includes a gun housing 2 in which is mounted an electromagnet 3 with an oscillating armature 4 actuated by alternating current from a switch 5 in a depending handle portion of the housing 2.
  • a supply container 6 is removably suspended from the housing 2 and feeds liquids, such as paint, through a suction tube 7 suspended from a cover or lid 8 for the container 6.
  • the lid 8 is a portion of a one-piece injection molded plastics material or die cast metal part suspended from a bore 9 of the gun housing 2 and has a sleeve-like pump housing portion 10 removably seated in the bore 9 and molded or cast around a hard metal cylinder sleeve 11.
  • a piston 12 is slidably mounted in the cylinder 11 and a pumping chamber 13 is provided ahead of this piston 12.
  • a return spring 14 in the bore 9 of the gun housing 2 biases the piston 12 against the armature 4.
  • the lid or cover portion 8 and the pump housing portion 10 of the one-piece molded or die cast part are joined by a neck 21 fitting snugly in an open front bottom recess 22 in the bore 9 of the gun housing 2 and a flat bottom wall 23 of the gun housing receives the flat top of the cover or lid snugly thereagainst with the periphery of the top of the lid being bottomed against a shoulder 24 acting as a stop member on the bottom of the gun housing 2.
  • a hollow stem 25 depends from the lid and has a tapered bore therethrough receiving the suction tube 7.
  • a passageway 26 is also provided through the lid and neck 21 adjacent this stem 25.
  • the hollow interior of the stem 25 is connected through an aperture 27 in the cylinder sleeve 11 with the pumping chamber 13 of the sleeve.
  • An opening 28 in the sleeve 11 joins the passageway 26 with an enlarged internal collection cham ber 29 in the sleeve 11.
  • the sleeve has an annular recess 30 therearound filled with plastics or metal material from the molding or die casting operation to integrally lock the sleeve with the pump housing portion 10.
  • the bore 9 of the gun housing 2 has an internal shoulder 31 forming an abutment for an annular collar 32 integral with the pump housing portion 10 to limit the insertion of this pump housing portion 10 in the bore 9.
  • a securing ring 33 rotatable on the outer end of the pump housing 10 is screwed into an internal thread 34 in the outer end of the bore 9 against the collar 32 to secure the collar against the shoulder 31.
  • the pump housing 10 is tightly anchored in the bore 9.
  • the spray nozzle 16 is threaded on the projecting front end portion 35 of the pump housing 10 which has external threads 36 for receiving the internal threads of the nozzle 16.
  • Container 6 has an externally threaded neck threaded in the internal thread 37 of the cover or lid 8, to provide a liquid-tight connection between the container and cover so that liquid will not spill out of the container even when the spray gun has fallen over or is laid down.
  • the handle portion of the gun housing 2 is manually gripped and the switch 5 is depressed by the index finger of the gripping hand whereupon the electromagnet 3 will be energized to oscillate the armature 4 thereby driving the piston 12 to the left as viewed in FIG. 1 and displacing liquid in the pumping chamber 13 to unseat the outlet valve 15 and discharge the liquid through the nozzle 16.
  • the inlet aperture 27 is closed by the piston.
  • the spring 14 causes the piston to follow the armature thereby retracting the piston to the right on a suction stroke closing the outlet valve 15, uncovering the aperture 27 and sucking liquid from the container 6 through the tube 7 into the pumping chamber 13. Liquid finding its way between the piston 12 and the cylinder 1 l is collected in the enlarged collection chamber 29 and drained back to the container 6 through the opening 28 and the passageway 26.
  • the securing ring 33 is unthreaded from the threads 34 and the entire pump assembly is easily pulled forwardly out of the gun housing since the pump housing, and the lid or cover 8 are all part of the same one-piece member. Then it is easy to remove the piston, the valve, and the spring of the pump assembly for repair, or replacement. Cleaning of the pump components is, of course, also facilitated.
