United States Patent 3,352,364 JACKET TYPE SPRINKLING AND SPRAYING DEVICE Clarence J. De Coste, 58 Shore Road, East Providence, RI. 02915 Filed Sept. 17, 1965, Ser. No. 487,989 4 Claims. (Cl. 169-1) ABSTRACT OF THE DISCLOSURE A portable fire-fighting apparatus which is self-contained and includes a manually operable and controlled nozzle and a sprinkler mounted on the apex of a helmet or hard hat which discharges water or other fire-fighting fluid laterally outwardly in a manner not only to assist in putting out a fire but also to protect the user from burn injury and other dangerous conditions which he may encounter such as conditions of extreme heat, exposure to flames and the like. A self-contained tank which can be pressurized together with a control valve is provided with the tank being integral with a jacket to facilitate movement to the user without interference from the apparatus.
This invention relates generally to portable fire fighting and fire protective apparatus and more specifically to a jacket type portable device adapted to be worn by a fireman or other person engaged in saving the lives of those trapped in flame engulfed areas and includes a hat mounted means useful in conjunction with the device for the purpose of fighting fires.
Many persons have died or have been seriously injured while fighting fires or while attempting to rescue those trapped by fires due to the extreme heat and flames normally attendant to such fires. Various protective devices have been devised to provide protection for such persons; however, these devices have proved to be generally unsatisfactory due to the rather high cost and/or weight thereof.
Accordingly, it is the object of the present invention to provide a lightweight fire fighting and fire protective apparatus which is inexpensive to manufacture while at the same time being extremely eflicient for its intended purpose.
In accordance with the above object, it is a further object of the present invention to provide a fire protective device adapted to be worn on the body of the user and including built-in fluid containing, spraying and dispensing features.
It is another object of the present invention to provide fire fighting apparatus adapted to be worn on the users head and body including novel and unique tank means and fluid outlet means for enabling the user to effectively fight fires while at the same time be protected from the extreme conditions encountered thereby, leaving his hands free to perform other required functions.
A still further object of the present invention is to provide novel hat mounted fluid sprinkler structure useful for protecting the wearer from flames or excessive heat while fighting fires or the like.
These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

FIGURE 7 is an enlarged partial vertical sectional view taken substantially on the plans of the line 7-7 of FIGURE 2.
Referring now to the drawings in greater detail, reference numeral 10 denote generally the fire fighting device comprising the present invention. The fire fighting device 10 comprises a jacket 12 preferably of approximately fingertip length and fabricated of rubberized or heavy duty plastic generally fire and heat repellent material. The jacket includes conventional closures or clasps 14 for fastening thereof and further has a sack or pouch 16 of similar material bonded or molded to the rear portion thereof as indicated by reference numeral 18. The dimensions of the pouch are preferably 16 inches wide by 24 inches high by 6 inches deep thereby enabling the pouch to contain slightly over nine gallons of conventional fire fighting fluid 20 in the chamber 26 defined therein. However, it will be appreciated that the volume of the pouch 16 may be either increased or diminished if so desired.
The pouch 16 includes a threaded stem 24 defining an opening in the upper wall 23 thereof, and a cap 22 which may be screwed on thestem 24 for closing or opening the opening in the pouch 16. The stem 24 is bonded or molded in an opening in the upper wall 23 of the pouch, the opening in stem 24 being provided in order to introduce conventional fire fighting fluid material 20 into the chamber 26 within the pouch. A discharge tube 28 is also mounted in the stem 24 and extends downwardly in the chamber 26 terminating in an open end 30 adjacent the bottom wall 27 of the pouch.
In order for the fluid 20 to be discharged upwardly through tube 28 and stem 24, the fluid level generally indicated by reference numeral 30 is normally below the upper wall 23 of the pouch, thereby leaving an empty space 34 in the upper portion of the chamber 26 when the chamber is filled to level 30 with fluid 20. A charging valve 36 is mounted in the upper wall 23 for introducing charging media, such as air or other conventional charging fluid into the empty portion 34. The valve 36 may be of any conventional variety, it being contemplated that a Schrader valve will be suitable for the intended purpose. Thus, the pouch may be charged, thereby creating pressure on the fluid 20 which causes the fluid to rise in pipe 28. Except for cap 22 the fluid would thereby be forced out of the pouch under pressure.
The screw cap 22 has a conventional pressure reducing valve 38 mounted on the upper portion thereof, the pressure reducing valve 38 also including a pair of T-arms 40 and 42 leading therefrom. A handle 44 is mounted on the valve control stem 46 for conventionally operating the pressure reducing valve 38 in a manner well known to those skilled in the art. Thus, by operating the handle 44 the valve 38 may be opened or closed to allow the fluid 20 to flow through the T-arms 40 and 42. The arms 40 and 42 include conventional threaded nipples 48 and 50 on the outer ends thereof into which are threaded the threaded ends of a pair of hoses 52 and 54. The hoses 52 and 54 having mounting nuts 56 and 58 thereon to retain the threaded ends thereof in the nipples 48 and 50.
The hose 54 includes a spray nozzle 60 threadedly received at 62 on the end thereof opposite the end coupled to nipple 50.The nozzle 60 is of generally conventional configuration comprising a metal spray nozzle including the operating handle 64 thereon having valve operating rod 66 attached thereto for operating a conventional internally mounted valve. Further, it is anticipated that the spray from the nozzle may be adjusted in a manner well known to those skilled in the art. The jacket 12 includes a mounting bracket 68 attached to the front portion thereof by conventional attaching means such as threaded coupler 70 and bonded portion 72. The mounting bracket 68 is provided for hanging the nozzle 60 therein when the nozzle is not in use, as illustrated in FIGURES 3 and 4, thereby providing a readily accessible position for the nozzle 60 while at the same time allowing the nozzle to be retained out of the way of the user of the device.
The hose 52 is coupled at the end remote from nipple 48 to a hat mounted sprinkling device generally denoted by reference numeral 74. The sprinkling device 74 is mounted on a conventional fireman-type hat 76, which hat ispreferably fabricated of Plexiglas or other substantially sturdy and lightweight material. The hat 76 includes a chin mounting strap 78 for retaining the hat on the users head, and a flat portion 80 at the apex thereof at which point the spray nozzle 74 is mounted. The hose 52 is connected to the spray nozzle 74 by threaded coupling 82. The spray nozzle 74 includes a body portion 84 of generally cylindrical configuration including a fluid receiving chamber 86 opening at 88 as an inlet to the hose 52. Mounted at'the top of the body 84 and rotatably held therein by the peripheral notch 90 in the inner wall of body member 84 is the. rotating sprinkler section 92. A mounting flange 93 is retained in notch 90 by cap 100. The rotating sprinkler section 92 includes an upstanding body portion 94 opening at one end to chamber86 and four integrally formed arms of identical construction 96 extending perpendicularly therefrom in oppositely paired relationship. Each arm 96 is open at one end to the body portion 94 and is preferably approximately two inches long by one-half inch in diameter. However, as will be appreciated, the size of the arms may be varied. Each arm 90 includes a sprinkler orifice 98 in the same side thereof and adjacent the end opposite the end opening to body 94. Thus, insofar as the sprinkler section 92 is rotatably mounted on the body member 84 and held thereon by cap 100, when the fluid 20 is forced under pressure through hose 52 into chamber 86 and upwardly through the body member 94 into the arms 96, the fluid will be sprayed out of the orifices 98 thereby causing rotation of the sprinkler section 92 as the fluid is projected from the sprinkler orifices due to the force impaired to the arms thereby. Further, the body portion 94 is capped by a capping member 102 having a pair of sprinkling orifices 104 and 106 therein, thereby allowing the fluid 20 under pressure to be projected upwardly and outwardly therethrough.
A circular metal guard 108 is maintained in encircling relationship to the sprinkler section 92 by being mounted on the body member 84 by a plurality of arms, 110, which arms 110 are braised or welded or otherwise mounted on the body member as illustrated at 112. The arms 110 are joined at their upper end by an encircling generally circular guard member 114 which together with the arms 110 protects the sprinkler 92 in case the hat 76 is inadvertently knocked to the ground. Incidentally, in this regard, if the hat 76 were to be knocked oft" the users head, the hose 52 will enable the user to quickly recover it, thereby eliminating the possibility of losing the hat.
The valve 38 permits fluid to be conveyed to the spray nozzle 60 and sprinkler section 92 at the same time when the control handle 44 is operated. Of course, when the handle 44 is turned to open the valve 38, the sprinkler section 92 will be immediately activated. However, in
order to allow the fluid to flow from the nozzle 60 the valve therein must be opened by handle 64. Thus, when,
valve 38 and the valve in nozzle 60 are both opened, fluid will flow from both the nozzle 60 and sprinkler section 92, whereas if the valve in nozzle 60 is not activated fluid will only flow from sprinkler section 92. If the valve 38 is only partially open, of course, the pressure of the fluid through the hoses 52 and 54 will be relatively slight and the fluid will be sprinkled or sprayed only in close areas. However, if the valve 38 is fully opened, the pressure will be greater and the liquid will be sprayed into a larger area. Further, the distance of spray from the nozzle 60 is variable by the handle 64 and control valve contained therein.
Thus, it willbe appreciated that the present invention comprises an extremely useful and novel device for firemen or others engaged in helping people escape from fire enveloped areas. The hat mounted rotating sprinkler section 92 will protect the fireman from the flames or excessive heat by allowing fluid to form an umbrella-like shield about him, and the fluid may alsobe conveyed from nozzle 60 to spray flames or may be turned on the operator in order to protect himself from flames and heat. Further, the sack or pouch 16 may be filled with fluid, charged and stored on a fire truck or the like along with the hat in order to allow firemen to quickly put the device onin case of emergencies when the use of the device is called for. At this time, the device can be quickly activated merely by turning handle 44, and the device may be used either with or Without the handheld nozzle 60.
The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.
