Rotatable Unit Patents (Class 239/538)
  • Patent number: 4638951
    Abstract: An adjustable pattern powder spray nozzle assembly comprising a nozzle body having an axial powder flow passage extending therethrough and a pair of rotatable adjacent shafts extending across the powder flow passage. The shafts are in contact with each other substantially along their length and each has a slot formed in the periphery thereof. The slots are oppositely positioned so as to define a powder flow opening therebetween. The shafts are interconnected by gears at the ends thereof so that they are rotatable in unison to vary the configuration of the opening and thereby, the pattern of powder sprayed from the nozzle assembly.

  • Patent number: 4579285
    Abstract: An adjustable orifice sprinkler unit includes a tubular body member with a rotatable cap mounted on one end thereof that cooperates with peripheral edges of the tubular body member for defining an adjustable arc spray orifice for adjusting a spray pattern from an angle of from about 0 degrees up to about 360 degrees with the cap adjustable axially of the tubular body member for selectively adjusting the height of the orifice opening.

  • Patent number: 4502640
    Abstract: A spray gun is disclosed intended alternatively for the application of plaster to walls, and the application of particulate finishing materials to the wet plaster. The gun has a hand held stock supporting a tubular housing, which receives at its front end interchangeable barrels having apertures in their side walls which can be brought into coincidence with an aperture in the housing communicating with a supply of material to be sprayed. One barrel has a handle so that it can be rotated in the housing to adjust the degree of coincidence between the openings and thus control release of particulate material into the barrel, while the other barrel is provided with a nozzle for the spraying of plaster. Compressed air for carrying out the spraying is admitted through an axial pipe connected to an external trigger.

  • Patent number: 4272025
    Abstract: A water distribution system for spraying a plurality of fine streams of water in a relatively uniform manner onto an ice forming surface. A hollow spraying tube is rotationally and coaxially disposed in a shielding tube of larger diameter. The shielding tube has an elongate slot extending substantially the axial length of the spraying tube such that streams of water are sprayed through those orifices in the spraying tube not shielded by the shielding tube and through the elongate slot. The width of the slot determines the angular arc of spray from the system. The shielding tube is adjustably secured to one side of a turbine housing to adjust the spray direction. A turbine blade assembly is rotationally disposed within the turbine housing and is operatively connected to the spraying tube. Pressurized fluid through an inlet of the turbine housing rotationally drives the blade assembly and the spraying tube and the water is discharged in an unpressurized condition through an outlet of the turbine housing.

  • Patent number: 4234128
    Abstract: An adjustable nozzle assembly for a hand operated compression sprayer is disclosed. The nozzle is attached to the discharge end of the sprayer and is adjustable from an off position to two discharge positions, such as a spray position and a stream position. The nozzle and sprayer body have cooperating passages which, when brought into register by adjustment of the nozzle, determine the discharge mode (i.e., whether off, spray or stream).

  • Patent number: 4085895
    Abstract: A simple, two-part adjustable spray device is disclosed, the device consisting of a tubular member within which is a cylindrical insert member. At its inner end, the insert member includes a chamber in selective communication with both the inlet portion of the tubular member and a longitudinal channel formed in the internal wall of the outlet portion of the tubular member. The side wall of the insert member defining the chamber is sufficiently flexible to be distended by the pressure of liquid within the chamber into a sealing engagement with the interior side wall of the tubular member. By rotationally adjusting the insert member, the chamber may be brought into selective communication with the longitudinal channel to allow a varying volume of liquid to pass from the inlet to the outlet and a spray of liquid to be emitted through a profiled aperture.

  • Patent number: 4020982
    Abstract: A multiple purpose nozzle includes a tubular member having a bore and communicating passage network therethrough and through which material to be dispensed is adapted to pass. An adjustable cap is coupled with the tubular member having an orifice in the end wall thereof of predetermined configuration. The cap is coupled to the tubular member so that it may be shifted between shut-off and open positions. In addition the cap is provided with a passage which form part of the passage network when the cap is shifted to the open position. In the closed position the cap passage is not aligned with the passage network of the tubular member and thus prevents the material from being dispensed. The cap is adapted to assume at least one other and open position at which the cap passage is aligned with the passage network and the material to be dispensed is adapted to pass in a selected predetermined discharge pattern through the bore passage network and orifice.

  • Patent number: 3967765
    Abstract: A nozzle located at the discharge end of a container includes a tubular member and a cap thereon. The tubular member has a passage in communication with the container interior for passage therethrough of the container contents to be dispensed. The cap is adjustably mounted on the tubular member and is capable of being turned to a first position at which the passage of the tubular member is closed to prevent the passage of the material to be dispensed. The cap is adapted to be turned to a plurality of discharge positions depending upon the discharge pattern desired. In these positions the passage is open and is placed in communication with a discharge opening and surrounding recesses in the closed end of the cap through a passageway defined by cooperating surfaces of a slotted core portion and surrounding slotted core skirt of the tubular member and a slotted boss cooperating with the core and skirt of the tubular member when the cap is assembled to the tubular member.
