  • a primary objection to this prior art apparatus resides in the fact that a plurality of sprinklers are usually required to effectively protect the enclosure. Further. the prior art sprinklers are conspicuous and detract from modern architectural designs.
  • an object of the present invention to provide a thermally actuated fire sprinkler which pro vides a more efficient and effective distribution of fire extinguishing fluid.
  • the inventive sprinkler be mounted normal to a side wall of the enclosure to be protected thereby eliminating the need for elbow joints.
  • Another object of the present invention is to provide a fire sprinkler having a relatively narrow transverse dimension.
  • the present invention contemplates a sprinkler providing a controlled distribution of fluid in a con-- fined enclosure. It comprises a nozzle having an orifice through which the fluid is discharged under pressure. Deflector means of substantially wedge shape are disposed in the discharge path of the fluid. The deflector means includes a leading edge formed at the narrow in cluded angle having a substantially zero angle of attack relative to the discharged fluid. The deflector means effects the desired controlled distribution and are supported in the path of the fluid by yoke means opera tively associated with the nozzle.
  • the deflector means comprises two wedge shape members substantially diametrically positioned in the path of the fluid discharging from the no/zlc.
  • Each wedge member is individually supported by separate yoke members fixedly mounted to and extending from the nozzle and configured to place the wedge members in the path of the fluid. In this configuration. the angle of attack of the respective leading c..- U a.
  • edges of the wedge members is approximately zero and the narrow included angle of each is in a range between approsimately I(J and approximately h(I.

  • FIG. 2 is a perspective view of a typical wedge shaped member
  • FIG. 3 is a schematic pictorial representation of a wetting pattern produced by a particular embodiment of the present invention.
  • FIG. 4 is a plan view of a flat pan distribution of fluid produced by the same inventive embodiment as FIG. 3;
  • FIG. 5 is a schematic pictorial representation of a netting pattern produced by another embodiment of the present invention.
  • FIG. 1 there is displayed a typical em bodiment of the improved nozzle-deflector portion II) of the present invention.
  • a nozzle member 11 is normally thread-ably engaged by means of thread portion 18 to a thermally actuated fluid control valve or line.
  • the thermally responsive portion of the sprinkler is described in copending application Ser. No. 336.849. filed Feb. 28. I973 now US. Pat. No. 3.834.463 and entitled Sensitive Sprinkler and assigned to the assignee of the present invention.
  • Nozzle 11 is of standard design including a shank section about which pcriphery threaded portion 18 is formed and an integral flange member extending axially and radially beyond the diameter of the shank section.
  • That portion 19a of the internal chamber communicating with the fluid source is of frusto-conical shape having its largest diameter D at the input end and the smaller diameter C at its exit.
  • the discharge orifice portion 19 is of cylindrical shape smoothly intersecting with the walls of frusto-conical portion 190.
  • the diameter of orifice 19 is. of course. the same diameter C.
  • yoke means including yoke members 12 and I4.
  • Yoke members 12 and 14 are attached to nozzle 11 by serrated portions at their respective ends engaging complementary through holes in nozzle 11 flange.
  • the complementary through holes are of se lected dimension so as to provide the appropriate interference when erimped or fastened to yoke members 12 and 14 thus providing a locking function. It should be mac noted that yoke members l2 and I4 and edge mem bers l3 and I5 protrude from the wall.
  • Yoke members 12 and 14 generally extending anally are inclined tonard the center line of noz/le ll thereby placing wedge members 13 and 15. respectively. in diametrically opposed positions in the path of the fluid discharged through orifice l9.
  • ⁇ Nedge member I5 is shown as having a leading edge formed by narrow included angle 13 disposed at a /ero angle of attack a relative to the fluid discharged from orifice I). The leading edge is dislocated from the center line of orifice I) by a distance A and from the plane of orifice I) by a distance B.
  • FIG. 2 showing a perspective view of a typical embodiment.
  • a leading edge 30 having a length L is formed by the intersection of the wedge surfaces determinative of narrow included angle B.
  • Length L is determined both by orifice 1) size as well as the fluid distribution pattern desired and may be altered significantly to meet operating exigencies.
  • the thickness W is shown as a constant throughout the length L. Again. however. thickness W may be varied as may the included angle B. By utilization of such vari ations. it is possible to refine the geometry of the distribution pattern.
  • Protuberances 16 of substantially triangular shape are shown as extending above the top surface of wedge member 15 and are typical of the de' vices employed to further alter the distribution pattern.
  • protuberances I6 may take on a variety of shapes and its shape is not limited to that of triangular. These alterations and modifications. however. are not considered necessary in the achievement of the principal goals and objectives of the present in vention but are intended only as refinements thereto.
  • Wedge member 13 is arranged similarly to member IS except that its angle of attack (r ofthe leading edge is shown as slightly greater than zero.
  • the dimensions A and B from the center line and discharge plane or orifice 19, respectively are ofslightly different dimension. These dimensional alterations are in many applications necessary to achieve the performance parameters required within a particular enclosure for which protection is sought.
  • the means of attachment of wedge shape members 13 and 15 to yoke members 12 anti 14, respectively. are not of critical importance and may be achieved by welding. brazing. soldering. riveting. or threadable engagement. It is only necessary that the composite structure be of sufficient integrity to remain in the desired position during discharge of fluid through orifice I).
  • Yoke members 12 and 14 are advantageously formed from rod stock but again may be formed of other materials having sufficient strength so as to permit that minimum dimensioning necessary to avoid disruption of the pattern provided by deflector means 13 and 15.
  • yoke members 12 and I4 need not be attached to nozzle 11 flange but may be suitably engaged to other portions of the sprinkler assembly and even may be rotatably engaged so that the action of the discharge fluid causes placement of wedge members 13 and IS in the path of the discharge fluid. This latter approach in certain instances may allow for a design having further decreased transverse dimension and thus more esthctically pleasing.
  • FIG. 3 shows the wetting pattern achieved after a ten minute test in an enclosure 20.
  • the improved sprinkler [0 of the present invention wetted side walls 21 and 23, vertical wall 22, near wall 26, ceiling 24 and floor 25 in accordance with the pattern indicated by the wetting line indication of FIG. 3. Near wall 26 was 95% wet at the end of the test.

  • Near wall 26 achieved 95% wetting and side walls 21 and 23 achieved 84 jet wetting.
  • the present invention achieves an improved fire sprinkler producing con trolled fluid distribution patterns meeting requisite standards of operation. it further provides a device of reduced transverse dimension. in the examples shown being no greater than approximately 1 /2 inches from the entry port of nozzle ll to the end of yoke members [2 and 14.
