Definitions

  • Att0rney-Marshall & Yeasting ABSTRACT A device for delivering a flow of matter in a variable direction, comprising an inlet piece and an outlet piece, said pieces being interconnected in a ball-jointlike manner in which the forces caused by the flowing pressure and tending to move the two pieces apart are compensated by a tie member disposed in the flow passage through and between the two pieces.
  • This invention relates to a device for delivering a flow of matter, such as a liquid (e.g. water), foam and the like, in a variable direction.
  • a liquid e.g. water
  • An example of such a device is a watergun used for tire-extinguishing purposes.
  • the jetlike outlet piece must be able to take various positions with respect to the inlet piece, the latter taking a more or less fixed elevational position with respect to a supporting surface, such as the pavement of a street, a deck of a ship or the like.
  • a device comprising an inlet piece and a jetlike outlet piece, the latter consisting of two branches, the upstream ends of which are bent one towards another and are pivotally supported in the ends of a cross bore of the inletpiece, the latter being mounted for adjustment rotation about a vertical axis onto a water-supplyconnecting piece.
  • the water-supply connecting piece is supported on legs or fixed to the supporting surface.
  • a disadvantage with the transportable watergun is the tendency to be tilted rearwardly by the reaction force caused by the outflowing water jet, so that the device requires a continuous watch.
  • the construction is rather complicated in view of the two separate pivot connections and the two worm gear mechanisms as used for adjusting the positions of the outlet piece and of the inlet piece respectively.
  • A' disadvantage of the stationary embodiment of the wellknown water gun, e.g. on board of a ship is to be seen in the fact that the adjustment gears do not permit carrying out quick-and smooth movements of the outlet piece for compensating the continuous movements of the ship.
  • A'common disadvantage of both of the embodiments is the relatively large number of curves in the flowing path through the device, which means-a relatively high loss of pressure.
  • the invention aims at providing a device for delivering a flow of matter in a variable direction in which an outlet piece may be universally moved relative to an inlet piece in an easy manner, and even under high working pressures.
  • a device for delivering a flow of matter in a variable direction is provided,
  • FIG. 1 is a longitudinal section of a device according to the invention, suitable for displacement from one site to another, and shown in a central position;
  • FIG. 2 is a cross-sectional view of the same device, as seen according to the arrows IIll in FIG. 1;
  • FIG. 3 is a partially sectional view of a device according to the invention in a second embodiment, suitable for being installed in a stationary manner and shown in a central position;
  • FIG. 4 is an end view of the lower part of the device according to FIG. 3, as seen from the left in FIG. 3;
  • FIG. 5 is an enlarged cross-sectional view of a detail of the device accordingto FIG. 3 and 4 and FIG. 6 is an enlarged cross-sectional view of the same detail, but now seen according to the arrows VI-VI in FIG. 5.
  • the device shown as a transportable water gun consists of an inlet piece 10 and an outlet piece 11, the latter being movable relative to the former.
  • the inlet'piece 10 is provided with three support legs l2, l3 and 14, adapted to support the inlet piece 10 in a stable manner on a substantially horizontal surface.
  • the inlet piece has a supply-connecting part, which is formed by two connections 17 and 18, provided with exterior screw threads and adapted to be connected to tire hoses (not shown).
  • the two passages and 16 of the connections 17 and 18 merge into a single passage 19, which in turn merges into the space 20 of a cup-shaped end portion of the inlet piece 10, said end portion having a semispherical inner surface 21.
  • the outlet piece 11 has a central passage 22, gradually tapering in the outflowing direction.
  • a jet 24 is connected by means of a union 23.
  • This jet 24 is provided with internally disposed guide blades 25 and has an outlet opening 26 as an extension of the passage 22 of the outlet piece 11.
  • the outer surface of the outlet piece 11 is for the greater part machined according to a spherical surface, the diameter of which is slightly smaller than that of the cup-shaped end portion of the inlet piece 10.
  • About one-half of the spherical annular outer surface 27 of the outlet piece 11 is surrounded. and engaged by the cup-shaped end portion of the inlet piece 10, so that a ball-joint-like connection between the two pieces is formed permitting a universal pivoting movement of the outlet piece 11 with its jet 24 relative to the inlet piece 10.
  • the joint is sealed by means of a sealing ring 29, seated in a circumferential groove 28 of the surface 27.
  • the outlet piece 11 with its jet 24-when put into practice-- would be readily forced out of its cup-shaped seat by the action of the work pressure, which may be as high as 10 atm. or even more.
  • a different type of retaining and releasing member 34 is used, extending through a part of the space constituted by the passage 22, the space 20 and the passage 19.
  • the retaining and release member 34 is constituted by a tie rod having at its end facing towards the outlet piece 11 an eyelet or ring 33, which engages a ballshaped enlargement 31 of the central section of a cross pin 32 mounted in the outlet piece I1.
  • the center 30 of the ballshaped enlargement 31 coincides with the center of the spherical annular surface 27 of the outlet piece 11.
  • the inner circumferential surface of the eyelet or ring 33 cooperating with the ball-shaped enlargement 31 has been correspondingly spherically shaped.
  • An eyelet 35 is provided at the other end of the tie rod 34, said eyelet engaging an eccentrically disposed section 37 of a cross pin 36 mounted for rotary adjustment in the inlet piece 10.
  • a crank-shaped end section 38 of the pin 36 extends beyond the inlet piece and serves as a handle for adjustment purposes. By turning the pin 36 by means of the handle 38 the outlet piece 11 may be pulled more or less tightly into the cup-shaped portion of the inlet piece 10 through the tie rod 34.
  • An average angular position of the handle 38 and consequently the average effective length of the tie rod 34 corresponds with the relative position of the inlet and outlet pieces, in which the center of the ballshaped enlargement 31 and of the spherical annular surface 27 coincides with the center of the semispherical inner surface 21 of the inlet piece 10. In the latter position the sealing ring 29 is slightly compressed and the outlet piece 11 can be easily and universally pivoted relative to the inlet piece 10.
  • the effective length of the tie rod 34 may be slightly shortened by turning the handle 38, as a result of which the outlet piece 11 will become seated more tightly in the cup-shaped portion of the inlet piece 10.
  • the outlet piece 11 is shown in a central position, from which position the outlet piece may be universally pivoted through an angle A, which may be about 30. In the central position the angle of elevation is also about 30.
  • the pivoting range ofthe outlet piece 11 with itsjet 24 is determined by a cone having an apex angle of 2A.
  • the mechanical limit of this pivoting range is formed by a circumferential shoulder 39 at the intersection between the spherically shaped surface 27 and the remainder of the outer surface of the outlet piece 11.
  • the shoulder 39 cooperates as an abutment with the edge 40 of the cup-shaped portion of the inlet piece 10.
  • FIG. 36 show a water gun constructed according to the invention and adapted for being fixedly mounted on a supporting surface, e.g. on the deck of a ship or on a vehicle.
  • the supply-connecting piece 50 having a flow passage 53, constitutes a separate piece, onto which the inlet piece 52 is mounted for adjusting rotation about a vertical axis 51.
  • the supply-connecting piece 50 is adapted to be connected with its lower end to a stationary water supply pipe (not shown).
  • the inlet piece 52 has a cup-shaped end portion 55, similar to the cup-shaped end portion of the inlet piece 10 in the first embodiment, while the construction of the outlet piece 56 with its jet 60 is also similar to that of the outlet piece 11 with its jet 24 in FIG. 1 and 2.
  • the inlet piece 52 is substantially shaped as a bend, having at its downwardly facing end 54 an axially extending collar 70 surrounding an upper flange of the supply-connecting piece 50 with a small clearance.
  • an inner circumferential groove 74 and an outer circumferential groove 72 are machined, said grooves forming together an annular track for a plurality of balls 75.
  • the balls 75 provide for an antifriction bearing for the inlet piece 52, enabling an easy turning movement of the inlet piece 52 relative to the connecting piece 50.
  • the connection between the two pieces 50 and 52 is sealed by an O-ring 80 seated partially in a groove 79 and partially in a groove 78 machined in the opposing surfaces 77 and 76 respectively of the connecting piece and the inlet piece.
  • the collar 70 is provided with a hole 90, intersecting the groove 72 in such a way that the balls may be readily introduced into the ball track through the said hole, when the two pipes 50 and 52 are assembled.
  • the hole is plugged by a pin 91, locked in place by a locking screw 92.
  • the inlet piece 52 may be fixed in an adjusted angular position by means of a cam lever 81, pivotally connected to the collar 70 about a pivot pin 82, the cam 83 of which cooperates with an annular bearing surface 84 of an intermediate flange of the connecting piece 50.
  • the cam 83 may be urged to move the inlet piece 52 and the connecting piece 50 slightly apart, due to which the two pieces become clamped more or less tightly one relative to the other through the balls 75, after which it has become more difficult to turn the inlet piece relative to the connecting piece.
  • the water gun according to FIG. 3-6 is provided with a tie rod 62 similar to the tie rod 34 in the embodiment of FIG. 1 and 2.
  • a tie rod 62 similar to the tie rod 34 in the embodiment of FIG. 1 and 2.
  • the upstream end 61 of the tie rod extends beyond an enlargement of the inlet piece 52 and forms a bearing 63 carrying a cam lever 64, the cam 65 of which cooperates with a flat end surface 66 of said enlargement.
  • the cam lever 64 By turning the cam lever 64 in one direction or the other, the tie rod may be pulled more or less tightly and as a result of this the outlet piece 56 will become seated more or less tightly in the cup-shaped end portion 55 of the inlet piece 52.
  • corrosion-resistant material such as stainless steel, bronze and the like.
  • a device for delivering a flow of matter in a variable direction comprising an inlet piece having supply-connecting means, and an outlet piece pivotally connected with said inlet piece, in which the interconnected ends of the two pieces have mating partially spherically shaped inner and outer surfaces respectively, a tie member being provided in the flowing passage between the two pieces, said member being connected to said outlet piece at a point adjacent the center of the common spherical surface, defining said inner and outer surfaces, and on the other hand being connected to a point of said inlet piece located upstream of said center, the inlet piece being mounted for an adjusting rotary movement about a vertical axis on a stationary connecting piece, characterized in that the inlet piece is carried out as a hand, one axis of which is directed along the average elevation angle of the outlet piece, and the other axis of which is directed downward and has an axially directed collar enclosing an upper flange of said connecting piece and being supported by said flange with the intermediary of a ring of balls disposed
  • a device characterized in that a cam lever is disposed between the collar and an intermediate flange of the connecting piece, said lever being adapted to exert an axial force tending to move the inlet piece and the connecting piece apart.
  • a water gun for fire extinguishing comprising an inlet piece having supply-connecting means, and an outlet piece pivotally connected with said inlet piece, in which the interconnected ends of the two pieces have mating partially spherically shaped inner and outer surfaces respectively, a tie rod being provided in the flowing passage between the two pieces, having one end engaging said outlet piece along a partially spherical surface concentrically disposed with respect to the center of said mating partially spherical surfaces, and having its other end engaging said inlet piece at a point upstream of said center on the cam surface of a rotatable cam, said cam being provided with an external handle for rotating said cam to vary the tension in said rod.
