A DEVICE FOR A FIRE EXTINGUISHING HOSE REEL

Abstract: Device for a fire hose with reel where the hose by preference is made of reinforced rubber (non rigid type) which can be laid out while the water-pressure is on and in such a way that the nozzle at the end of the hose can be used everywhere within the length of the hose without using a reel with a nave revolving on a fixed hollow axle which the water is passing through. According to the invention the main part of the hose is connected to the water supply pipe and is rolled up on a reel in the usual way and the invention is characterized in that the last part of the hose (6') with the nozzle is coiled up on the side of the reel (25) and is detachably fastened to it so that the main part of the hose is rolled out while carrying or rolling the reel toward the fire. On any suitable place the hose can be released so that the nozzle can be used everywhere within a certain distance from the reel.

Description: 1 A " device for a fire extinguishing hose reel. The purpose of this invention is to lay out a fire hose and o every point of time be able to use the nozzle in all directions without using expensive and complicated devices for the supply of water tc the hose through- the nave of the reel or the like. Fire hoses with nozzles particularly those with rein¬ forced rubber hoses for industry, institutions, schools hotells and the like and also for private homes nearly allways have the water supply from the water pipe through a shut-of cock and a pipe or a hose to an hollow axle and then the water flows into a nave which is rotating on the axle and is connected to the fire hose. This construction has many possibilities for leakages. The nave rotates on the hollow axle and the packings at both ends of the nave can become leaky. The rotation of the reel must be braked so that no uncontrolled rolling out of the hose can occur and therefore the rolling out of the fire hose when it shal be used will also be braked. Fur-her- more this construction will be very heavy and there¬ fore the devices carrilng the reel must be very- strong and heavy. The hose must also be fastened to aniple on the nave of the reel. This will cause a sharp bend on the hose and it will very soon be damaged there unless it is taken special measures for example putting in an helical saring into the hose. The Swedish patent no. 154 163 describes a construc¬ tion where the first part of the hose with the nozzle has been drawn through a hole in the cylinder lining on which the other part of the hose is rolled up. hen the first part .of τjhe hose is coiled up inside the said cylinder lining and the nozzle is fastened en the side of the reel. 7hen the first τjart tf the hose (which ought to be 4-5 meters long) is drawn out, the nozzle will turn round just as many times as there are coils in the cylinder lining which undoubtedly will cause "cracks" on the rubber hose which again will stop the water supply and the hose will also fasten on the edges. Furthermore experiments has shown that the coils will fall out to the side if they are not kept in place by a device when the other part of the hose is rolled out. Furthermore it is very difficult to coil a rather rigid reinforced rubber hose into a c3linder lining with a sa all diameter without having "cracks" on the hose. In the Swedish patent the nozzle is fastened en the side of the reel. This will increase the width of the construction and make the boxes in which t e fire hoses are kept wider and that will be a very big draw¬ back in a building. To avoid this the nozzle can be put into the center of the coils, but as the nozzle with its hose niple is of* rather big length one will allways have a "crack" on the hose there and that will in due time cause a fracture on it. The intention of this invention is in a simple way to lay out a fire hose and on any place during the layout be able to move the nozzle and a part of the hose freely in all directions without using complicated devices as described. The invention is characterized in the constructions mentioned in the claims of patent no . 1,2,3 and 4. In this way one will have a much simpler and cheaper conεtructionwith fewer possibilities of leakages and mechanical defects. The fitting-up will also he easi¬ er, the ".vhole device will be lighter and the hose can be laid out easier and faster. It must be pointed out that if a hose is drawn out from a reel wit -water supply through the center and it shall be drawn through a door-onenins or rjast a corner It is reces- 3 sary to have a person standing at such places to re- farward the hose. The hose according to the inventi¬ on can on the other hand be laid out by only one person at all events. When the last part of the hose with the nozzle is coiled up on the side of the reel, this reel will have smaller dimensions than a reel according to the Swe¬ dish patent or a reel with supply of water through the center of the reel. When the last part of the hose is drawh out from the side of the reel, the nozzle willwill turn around only less than half as many times as it will do on the construction according to the Swedish patent. So few turns of the nozzle will be assesed by the rubber hose without any "cracks". On the drawing fig.1 is shown a cross section of a reel and fig.2 shows the same reel seen from above. Fig.3 shows a cross section of another reel and fig. 4 that reel seen from the left. Fig.5 shows how the hose is rolled out. On the figures 1 and 2 there are two cross-shaped sides 1 and 2 on the reel 24. The sides are held to¬ gether by a cylindrical navepiate 3 which is fastened to the sides 1 and 2 and the whole construction rotat¬ es on an axle 4 which has a prolongation with a loop or the like 5 which can be used for hanging the reel on awall or the reel can be carried by It while one is running against the fire and the reel revolves leting the hose, hic is rolled up between the sides 1 and2 , out. On the outside of the side 1 there are taps 7 and the distance between each pair of them is smaller at the top of them than at the bottom near the side 1 in such a way that the hose 6 'can be pressed down between each pair of taps 7 so that it can be held firmly against the side 1. When assembling this reel the hose 6 is put down be¬ tween two arms of the side 1 inmost at the naveplate 3with such a length of the hose 6' outside the reel that it corresponds with the length needed to move the nozzle 8 uite freely. Then the hose 6 ' is pres¬ sed down between the taps 7 pair by pair round and outward. When the whole length 6' with the nozzle 8 is fastened, the rest of the hose 6 is rolled up on the naveplate 3 between the sides 1 and 2. Then the coupling 9 can be coupled to the water supply pipe. Instead of having the taps 7 elastical, they may be made rigid and with a distance between them so that the walls of the hose 6 are pressed together. When the hose reel is. used it must be taken down from the wall or out of its cabinet, the water cock is open¬ ed and the reel is carried along while the hose rols of. J-Tear the fire the reel Is laid down and the hose 6' which is fastened between the taps 7 on the side of the reel is taken up and the nozzle can then be moved freely in all directions at a maximum distance like the length of the hose 6'. The figures 3 and 4 are showing a construction of the reel 25 which by preference is used for greater dimen¬ sions of hoses. The end of the hose β which is fast - ened to the water supply 20 is rolled up on a cylind - rical naveplate 16 between spokes 11 with rings 10 and 10' -fastened to them. J5.ear the center the spokes 11 are fastened to a tube 12 which revolves on an axle 13. This axle is fastened to a plate 14 and on the top of it a handle protruding Inward over the reel is fastened. On the plate 14 there can be fastened signs with dir¬ ections for use. iϊe r the naveplate 16 one part 6' of the hose is drawn aside between two of the spokes 11 and is rolled ut> from the navenlate 16 and outward. O ?I <=. In the end of this part of t ' -. e lro r.e 6' the nozzle 8 is fastened and in order to oep the hose 6' with the nozzle 8 fastened to the side of the reel an elastic cross-shaped part 17 is fastened to the ring 10'. Farthest out on each end of the parts 17 an elastic part 18 is bent inward and then again outward 19 thereby holding the part 17 irmly against the side of the reel 25 with the hose 6' between. This reel is used in just the same way as described before and shown in fig. 5. When the reel 25 is laid down with the part 17 upward this part is taken of the reel and the nozzle can be used as described. There may be used different constructions for this purpose, but the imprtant thing is that the water cock on the supply pipe can be opened before the rol¬ ling out is started and that the part 6 ' of the hose v/ith the nozzle 8 can be operated quite freely with¬ out any risk for having "cracks" on the hose.
