Definitions

  • nozzles designed to be mounted on spray pipes for installation especially in places where available space is restricted. For example, in paper-making machines there are places where it is necessary or desirable to wash some parts of the machine, such as rolls, wires, felts, screens, constantly to avoid any accumulation of fibres which might create defects in the pulp sheet which is being made into paper. It is also desirable that such nozzles be easily cleanable without moving them from their places.
  • a nozzle is provided that is designed to be mounted in the side of a spray pipe so that most of the nozzle is within the pipe and very little protrudes outside.
  • the nozzle embodying the invention is of simple construction, is easily assembled, and is easily cleaned by shutting ofl temporarily the water or other fluid supplied to it.
  • Figure 3 is a perspective view of a seat member in the nozzle
  • Figure 4 is a perspective view of a spring part of the nozzle
  • Figure 5 is a plan view of the nozzle
  • Figure 6 is a fragmentary sectional view of the nozzle casing or body.
  • a spray nozzle embodying the invention is shown in Figure 1 mounted to project through the wall of a spray pipe 10.
  • the nozzle comprises a body 12 which is cylin drical and is externally threaded as at 14.
  • Thisbody has a central cylindrical bore 16 in which is slidably fitted a tubular cylinder 20.
  • the body 12 has a semi-cylindrical extension 22 which rounds off into a dome 24 extending across the outer end of the body 12 and spaced therefrom by a slot 26 which extends to the axis of the body 12.
  • a seat member 30 is secured in or is integral with the dome 24. This member is an obstruction opposite the outer end of the bore 16 to deflect the stream of water flowing through the bore and cooperates with the tubular cylinder 20 to form a spray of the fluid flowing therethrough when the member 20 is seated against it.
  • the face of the seat member 30 opposed to the bore 16 is given any esired contour according to the type of spray to be emitted from the nozzle. is shown as being conical for the most part as at 32, the cone being modified by a shallow concave gouge 34 facing the slot 26.
  • the tubular cylinder 20 has a central bore 40 which By way of example, this face ice serves as a passage for water leading from the pipe 10 through the spray nozzle.
  • the cylinder 20 has a neck of, reduced diameter 42 near the inner end thereof, forming a shoulder 44.
  • An annular washer. of rubber or equivalent material surrounds" the neck 42 and bears on the shoulder .44..
  • Fhe-qou-ter edgeror of the washer 46 restson the inner errd face 47 of the body member lz which face is countersunk so" that it slopes ebnicallyltoward--the-axis ofthe body member and is.
  • a flat spring 50 which is preferably H-shaped and of resilient material such as spring metal or a plastic is mounted upon the Washer 46 and straddles the neck 42, engaging under a head 52 on the neck.
  • the spring 50 has four legs, 54, 56, 58, 60, which make it more flexible and which engage under the flanges 49, 49' as indicated in Fig. 5 so that the spring resiliently supports the tubular member 20 in the position illustrated in Figure 1.
  • the member 20 is of sucha length that when supported in the position shown in Figure 1, its lower end is spaced from the seat member 30 sufficiently to permit a voluminous flow of water through its bore.
  • a spray nozzle comprising a cylindrical body with a central bore countersunk at one end thereof and an obstruction opposite the other end of said bore, a tubular cylinder loosely fitted within said bore and adapted to engage said obstruction to form a spray vent, said tubular cylinder having a portion of reduced diameter at the end thereof remote from said obstruction, said reduced portion terminating in a head of slightly larger diameter, a flat flexible washer surrounding said reduced portion and fitted in said countersunk end of the bore, and a leaf spring overlying said washer and extending the full width thereof, said spring engaging under said head to hold said washer in place.
  • a spray nozzle as described in claim 1 said body having spaced inturned flanges along portions of its countersunk end, said leaf spring having end portions engaging under said flanges.
  • a spray nozzle comprising a cylindrical body with a central bore countersunk at one end thereof and an obstruction opposite the other end of said bore, a tubular cylinder loosely fitted within said bore and adapted to engage said obstruction to form a spray vent, said tubular cylinder having a portion of reduced diameter at the end thereof remote from said obstruction, said reduced portion terminating in a head of slightly larger diameter, a flat flexible washer surrounding said reduced portion and fitted in said countersunk end of the bore, and a leaf spring overlying said washer and extending the full Width thereof, said spring engaging under said References Cited in the file of this patent UNITED STATES PATENTS 1,272,274 Kinealy July 9, 1918 Flannery et al Mar. 4, Collis Dec. 31, Lincoln Sept. 6, Griswold May 12, Bates Oct. 25, Bloom Jan. 8, Goyette et al Aug. 20,
