57 ABSTRACT Afire hose nozzle is sharpened to a bayonet-like point at its forward end, thereby enabling the operator to gouge a pit or open a crack in a wall to be breached. A high pressure stream ofwater issuing from the nozzle and striking the pit or crack is sometimes effective through pressure alone to enlarge the surface opening and ultimately breach the wall. By injecting a charge of abrasive material into the high pressure water stream,
the area of weakness formed by the pit or crack quickly enlarges and soon causes the wall to rupture and give way since the erosion of the pit or crack is greatly accelerated by the abrasive material entrained in the high velocity water stream. 1
4 Claims, 5 Drawing Figures WALL BREACHING ATTACHMENT FOR FIRE HOSE The invention relates to improvements in fire fighting equipment used to breach walls, partitions, dividers and the like.
It frequently becomes necessary in the course of fighting a fire to obtain access to an adjacent space separated from the fire fighter by a wall in which there are no convenient window or door openings. Walls, whether of wood, masonry of of composite construction, such as stucco and paneling or gypsum board and plaster, for example, are often very difficult to penetrate. I-Ieretofore, hand axes and in some cases jackhammers have been required to breach the barrier, procedures which are not only cumbersome and fatiguing, but also time-consuming.
It is therefore an object of the invention to provide a wall breaching attachment for a fire hose which is effective to initiate a surface weakness in the wall, in the form of a pit or a crack, then to place the weakness under great stress by directing a high pressure stream of water against the pit or crack, and finally to abrade or wear away the wall material adjacent the weakened area by introducing abrasive material into the stream flow so that the dynamic force of the water can readily rupture the weakened portion of the wall and thereby provide access to the adjacent space.
It is another object of the invention to provide an attachment of the foregoing kind which is relatively small, compact, light in weight and readily maneuvered, yet which is rugged, durable and long-lived, and which in no way interferes with the operation of the nozzle itself.
It is yet another object of the invention to provide a wall breaching attachment which is relatively inexpensive but is efficient in operation.
It is a further object of the invention to provide an at tachment which can be utilized to advantage in breaching walls, dividers and the like of many different kinds and sizes.
It is another object of the invention to provide a generally improved wall breaching attachment for a fire hose.
Other objects, together with the foregoing, are attained in the embodiments described in the following description and illustrated in the accompanying drawing, in which:
FIG. 1 is a top plan view of one form of the device;
FIG. 2 is a median, vertical, longitudinal, sectional view of the FIG. 1 form of device;
FIG. 3 is a transverse sectional view taken on the line 33 in FIG. 2;
FIG. 4 is a fragmentary sectional view, to an enlarged scale of the screen gate retainer shown in FIG. 2; and,
FIG. 5 is a fragmentary median, vertical, longitudinal sectional view of a modified form of abrasive material conductor, or injector, showing a canister discharging its contents into the injector.
While the wall breaching attachment of the invention is susceptible of numerous physical embodiments, depending upon the environment and requirements of use, substantial numbers of the herein shown and described embodiments have been made, tested and used and all have performed in an emimently satisfactory manner.
The fire fighting attachment of the invention, generally designated by the reference numeral 12, comprises an elongated nozzle 13 extending from an after, inlet end 14 to a forward, outlet end 16, at which point a stream of water emerges through the discharge port 17 under conditions of extremely high pressure and velocity. The dynamic force exerted by a stream of water emerging from the customary fire hose is surprisingly great, and this attribute is taken advantage of in helping to rupture the wall to be breached.
The after end of the nozzle is provided with a threaded connector 21 for engagement with a conventional fire hose coupling (not shown).
From the connector 21, the nozzle converges toward the forward end 16, the tapering walls 22 of the nozzle defining a converging channel 23 which increases still more the velocity of the stream of relatively incompressible water flowing therethrough.
Adjacent the upper forward end of the nozzle, the nozzle walls are shaped to form a bayonet-like point 26 which is driven against the wall with great force so as to gouge out a pit or start a crack in the wall. Once the surface opening is provided, the full force of the water stream can be directed toward the depression. In the fashion of an impulse turbine of the Pelton Wheel type, the reversal of water flow effected by the pit extracts a large portion of the impact energy of the water. As a consequence, even minute cracks and crevices in adjacent fracture planes, or planes of weakness are discovcred" and quickly enlarged in size by the erosive effect of the high velocity water. Often, the abrading away of the wall material adjacent the initial pit or crack resulting from the water alone is sufficient to rupture the wall.
However, the wearing away process is greatly accelerated by introducing into the high pressure water stream, at appropriate intervals, a suitable charge of abrasive material 31. The abrasive can be of lead or steel pellets, or shot, comminuted hard refractory material, cast iron fragments, or the like. Crushed brittle materials not only afford the impact effect, which serves to enlarge fractures surrounding the depression formed by the bayonet point, but they also provide a very effective abrasive effort owing to the numerous sharp corners and projections of the crushed fragments.
Serving both as a storage chamber and as a conduit for the abrasive charge 31 is an elongated, fore and aft conductor 32, or injector, mounted on the upper portion of the nozzle wall in substantial fore and aft alignment with the bayonet point 26. The conductor 32 extends angularly inwardly toward the nozzle axis from an after end 33 to a forward end 34. The charge 31 is introduced into the conductor 32 through a mouth 36 and is injected into the path of the high velocity stream of water through an opening 37 in the nozzle wall 22. In the form of the device illustrated in FIGS. l-4, the mouth 36 can be selectively covered and uncovered by a swingable gate 41 hinged on a cross pin 42 adjacent the bottom of the sloping face 43 on the after end of the conductor base 44. The gate 41 is formed by a bail 46 connected at its two bottom ends to the pivot pin 42, the upper portion of the bail being; covered by a screen 47 extending downwardly into abutment with the upper surface ofa planar sliding gate 51 supported on the planar upper surface of the conductor base 44. The swingable gate 41 is movable between an open position, shown in broken line in FIG. 2, and a closed position shown in full line in FIGS. 14. In closed, or covered position, the upper portion of the bail 46 detachably engages a detent member 48 formed on the upper after end portion of the conductor.
The slidablc gate 51 is movable between a closed position shown in full line in FIGS. 1-3 and an open position shown in broken line in FIG. 2, an upturned handle 53 at the after end facilitating movement of the gate 51. In closed position of the gate 51 the forward end portion 53 of the gate covers the nozzle wall opening 37 and precludes the entry of the abrasive charge into the high pressure stream of water flowing through the nozzle.
By closing the swingable gate 41 after the abrasive charge is placed in the conductor, the nozzle can be tilted upwardly to any desired attitude. The closed screen gate 41 prevents the abrasive material from pouring back out through the mouth 36.
When it is desired to inject the abrasive charge 31 into the high pressure stream, the operator grips the handle 53 and slides the gate 51 to open position. Gravity, but more particularly the reduced pressure result 'ing from the swift flow of water past the opening 37 sucks the charge 31 into the stream, at which juncture the abrasive material undergoes great acceleration and is driven against the previously weakened wall area at a highly destructive velocity. The gate 51 is thereupon slid into closed position and, if desired, the screen gate 41 can be swung open and a new charge of abrasive material from any suitable container (not shown) can be introduced, followed by again snapping the gate shut over the detent member 48.
For protection of the operator's hand while holding a pivoted foldable handle 61 on the bottom forward portion of the nozzle, 1 have provided a shield 62. The shield deflects any abrasive material which bounces or ricochets back from the wall after impact, and thereby keeps the handle area free and clear of abrasive and abrasive-caused debris.
FIG. illustrates a modified form of device wherein the conductor 132, or injector, can be charged by a canister 135 previously loaded with abrasive material 131. Just inside the mouth 136 of the conductor 132 is mounted a limit stop 140. Where the conductors inner walls are circular, the limit stop 140 assumes the form of an inwardly projecting ring. The limit stop 140 serves as a seat against which the forward margin 145 of the canister abuts when the canister is inserted in the conductor mouth 136 preparatory to recharging the conductor with an abrasive load.
The canister 135 is constructed so that its walls 155 are collapsible when a predetermined amount of force is applied against the base sealing plug 160, but are sturdy enough to retain the desired configuration under ordinary handling. The leading, or forward, end of the canister 135 is sealed by a star-shaped closure 165, or the like, similar to the closure on the forward end of a shotgun shell.
The loaded canister is inserted into the conductor 132 until the leading margin 145 abuts the limit stop 140. At this juncture, the base of the palm of the operators hand is firmly pushed against the base plug 160 causing the walls to collapse in accordian fashion. In FIG. 5 the walls are shown in their initial configuration, for the sake of clarity. The force is thereby transmitted through the contents against the inside surface of the star closure. As force against the base plug 160 continues to be applied, the star closure 165 is split apart, as
appears in FIG. 5, allowing the abrasive charge to pour into the conductor and thence through the opening into the high pressure stream of water in the nozzle. As before, the extremely high velocity flow of water instantaneously accelerates the abrasive particles and shoots them against the previously weakened area of the wall in a manner not unlike shooting a charge of buckshot against a target which is close at hand.
A highly destructive impact force is thereby brought to bear against the weakened area, causing further cracks and pits. Simultaneously, the bombardment of the area by the abrasive particles quickly erodes the remaining wall material. The combination of the two forces soon results in breaching the wall.
It can therefore be seen that l have provided an attachment for a fire hose which not only efficiently serves as a nozzle in the customary way, but which also enables the firefighter to utilize the device immediately, if need be, for breaching a wall in a swift and convenient manner.
