3 Claims. (01. me -145) ,This invention relates to a smoke-diifusing apparatusto be employed especially by firemen when fighting fires.
An object of this invention is to provide a ;smokedifiusing apparatus of simple and practical, construction which may be easily and quickly adjusted uponthe body of a fireman.
Another object is to provide: an apparatus which will effectively diffuse smoke in the vicinityycf theyflremans head, thereby permitting him to breathe more freely and reducing the possibility of suffocation.
The above and other objects of this invention may be realized through the provision of a perfo- :;rated member supported by a neck-band, a
waist-belt and a breast plate upon the firemans body and connected with means supplying air to said member.
The invention will appear more clearly from the following detailed description, when taken in connection with the accompanying drawing, which illustrates preferred embodiments of the inventive idea.
In the drawing:
Figure 1 is a side elevation, partly in section, of an apparatus constructed in accordance with the principles of this invention;
Figure 2 is a, perspective view showing the application of the apparatus;
Figure 3 is a section along the line 3-3 of Figure 1.
Figure 4 is a top view of a breast-plate forming a part of the smoke-diffusing apparatus shown in Figure 1;
Figure 5 shows a nozzle of a different type in side elevation; and
Figure 6 is a, section along the line 6-6 of Figure 5.
The smoke-diffusing apparatus illustrated in Figures 1 to 4 of the drawing is shown as comprising a pipe 7 having a laterally extending nozzle 8 provided with screw threads 12. A hollow ball 10 forms a single body with a nut 11 which is screwed onto the screw threads 9, or is otherwise connected with the nozzle 8 in an airtight manner. The hollow ball 10 is provided with a plurality of air openings 9 which are preferably distributed in a symmetrical relationship over the surface of the ball, so that the air discharged from the perforations can intermingle and create an air current which will efieetively diffuse the smoke.
The opposite end 13 of the pipe 7 may be connected in any suitable manner with an air hose '14, capable of supplying air under pressure to the ball 10 from any source,;not shown in the drawing, such as. a separate container, or a pump on the engine which is pumping the streams of water to the hose lines used to extinguish a fire.
.;In order that the supply or? air to the nozzle 8;may be controlled, the pipe 7 is provided adjacent its end 13 with a bearing 15 having a valve 16 rotatable therein so that itmay be turned to open and close the pipe 7 atthis. point, as shown in Figure 3 of the drawing.
The apparatus is conveniently supported upon the firemans bodyrin a position wherein the perforated ball 10 will be located adjacent his face so that as the air under pressure escapes through the openings 9 it will diffuse the smoke, as indicated in Figure 2, and thus permit freer breathing and reduce the possibility of suffocation. To this end, the apparatus is supported from the neck, the breast and the waist of the wearer in a substantially vertical position by means of a neck-band 29, a breast plate 21 and a waist-belt 22.
The ends of the band 20, which is adapted to be passed over the head to the position shown in Figure 2, are secured between the ends of a clamp 23, by a bolt 2s. The clamp 23 is slidable upon the pipe 7 and may be secured in ad justed positions thereon by means of a wing nut 25.
The breast-plate 21 which is used for preventing the pipe 7 from revolving, consists of wires forming an elongated oval member, which is slightly bent in conformity with the curvature of the body of the wearer, as shown in Figures 1, 2 and 4 of the drawing. The breast plate 21 is carried intermediate its ends by a conical support 26 which is rigidly connected with a hollow tube 27. A cylindrical end of a link 28 projects into the interior of the hollow tube 2'7 and is secured therein in adjusted positions by a wing nut 29 carried by the tube 27. The opposite end 30 (Fig. 4) of the link 28 is flat and is surrounded by the ends of a U-shaped clamp 31 which has an annular middle portion surrounding the pipe 7. The clamp 31 is secured on the pipe 7 by a bolt 32 passing through the ends of the clamp 31 as well as through the flat end 30 of the link 28.
The belt 22 which encircles the waist of the wearer is passed through a link 33 mounted upon the pipe 7 on opposite sides of the bearing 15.
The modification illustrated in Figures 5 and 6 of the drawing comprises a pipe 17, one end of which terminates in a laterally extending nozzle 18 having a plurality of air openings 19 therein, similar openings being also formed in the portion of the pipe adjacent the nozzle 18. The end 34 of the nozzle 18 is closed. The bent portions of the pipe 1'7 and the nozzle 18 which are furthest from the wearer, are not perforated as illustrated in Figure 6 of the drawing.
In operation, the nozzle 8, or the nozzle 18, are maintained in their proper position close to the face of the wearer by means of the neck-band 20, the breast-plate 21 and the waist-belt 22. Due to this arrangement the air escaping through the perforations 9, or the perforations 19, will permit the fireman to breathe freely and will diffuse smoke.
What is claimed is:
1. A smoke diffusing apparatus comprising a pipe, a perforated member connected with said pipe and forming a continuation thereof, an air hose connected to an end of said pipe for supplying air to said perforated member, a valve carried by said pipe and controlling the supply of air through said pipe to said perforated member, a'link mounted upon said pipe, a waist-belt connected to said link, a breast plate, and telescoping means connecting said breast plate with said pipe, said perforated member being supported in front of and adjacent to the face of the wearer.
2. A smoke diffusing apparatus comprising a pipe bent at one end to form a laterally extending nozzle, said nozzle and the portion of said pipe adjacent thereto having a plurality of perforations therein, an air hose connected to an end of said pipe for supplying air to said perforated nozzle, a valve carried by said pipe and controlling the supply of air through said pipe to said perforated nozzle, a link mounted upon said pipe, a waist-belt connected to said link, a breast plate, and telescoping means connecting said breast plate with said pipe, said perforations being distributed over portions of the pipe and nozzle which are close to the face of the wearer in operation whereby the air from the perforated member will intermingle and create an air current which will effectively diffuse the smoke, said nozzle being supported in front of and adjacent to the face of the wearer.
3. A smoke diffusing apparatus comprising a pipe bent at one end to form a laterally extending nozzle, a hollow perforated ball connected to the end of said nozzle, an air hose connected to an end of said pipe for supplying air to said perforated ball, a valve carried by said pipe and controlling the supply of airthrough said pipe to said perforated ball, a link mounted upon said pipe, a waist-be1t connected to said link, a breast plate, and telescoping means connecting said breast plate with said pipe, said nozzle being supported in front ofand adjacent to the face of the wearer.
