JOHN IV. REGAN, OF BOSTON, MASSACHUSETTS.

HOSE-NOZZLE.

SPECIFICATION forming part of Letters Patent N o. 568,876, dated October 6, 1896.

Application filed April 25, 1896. Serial No. 589,017. (No model.)

T 0 all whom it ntm/ concern;

Be it known that I, JOHN W. REGAN, a citizen of the United States, and a resident of Boston, in the county of Suffolk and State of Massachusetts, have invented new and useful Improvements in Hose-Nozzles, of which the following, taken in connection with the accompanying drawings, is a specification.

This invention relates to improvements in hose-nozzles for tire-hose; and it has for its objectto throw one or more flat or fan-shaped streams or sheets of water on burning buildings in case of fire, and it is particularly well adapted in theaters or similar halls, where it is desired to prevent a tire on the stage from reaching the auditorium by forming an intermediate liquid curtain, and this may be done either by means of my improved nozzles attached to stationary stand-pipes or forming part of portable hose-pipes, as may be desired.

The device, although particularly well adapted for confining fire in theaters or pu blic halls, dac., may to equal advantage be used for other purposes when it is desired to prevent spreading of tire to'adjacent buildings to the one on iire.

The device is also useful for fighting fire direct upon the burning building or materials contained therein, as will hereinafter be more fullyshown and described,reference being had to the accompanying'drawings, whereininvention.

Figure l represents a side elevation of my Fig. 2 represents a top plan view of the same, showing the slitted cap arranged for throwing sheets of water in two opposite directions. Fig. 3 represents a similar top plan view showing the said cap turned to one side, s0 as to bring its slits out of alinement with the slits in the ejector. Fig. 4. represents a similar top plan View showing the slitted cap turned to a position for throwing the sheet or sheets of water to one side of the central line of the ejector. Fig. 5 represents a central longitudinal section on the line 5 5, shown in Fig. 2; and Fig. 6 represents asimilar central longitudinal section on the line 6 6, also shown in Fig. 2.

Similar letters refer to similar parts wherever they occur on the different parts of the drawings.

A in the drawings represents the pipe,

which may be of any ordinary form or construction. either a stationary stand-pipe or aA portable one attached to the end of a line of hose, as is common in devices of this kind. To the screw-threaded end of said pipe is secured the internally-screw-threaded ejector B, as shown. Said ejector is provided at its upper end with one or more slits b b b, as shown in the drawings. The outer periphery of said slitted ejector is screw-threaded, and on it is adjustably arranged the internallyscrew-threaded cap C, provided at its upper end with an inwardly-projecting annular lip O', as shown.` Said annular lip C is provided with transverse slits C" C", which, when the cap C is turned to the position in Figs. 1, 2, and 5, are in alinement with the ejector-slits b b b, so as to cause the sheets of water ejected through the slits b and C C" to assume fan shapes extending in two opposite directions to the 'axial line of the pipe A.

At or about right angles to the slits C" are made similar slits O3 O3 C3 in the annularlip C', as shown in the drawings, the opposite portion of the said lip being unbroken, as fully shown in Figs. 2, 3, 4c, and 6, and when said slits C3 are in alinement with the slits b b h, as shown in Figs. 4 and 6, the sheet or sheets of water ejected through the slits b b b are caused to extend more to that side where the slits C3 are located as compared with the opposite side of the ring O, thus enabling'the iremen, by simply adjusting the position of said ring relative to the slitted ejector B, to cause the fan-shapedstreams to be ejected in opposite directions or to one side more than the other relative to the axis of the ejector, as may be desirable, according to the'nature and location of the fire to be extinguished or the surrounding objects or buildings to be protected.

1f the firemen desire to limit the lateral flow from the slits b in the ejector B, all that is necessary to do is to turn the cap C to the position shown in Fig. 3,.so as to cause the slits b to be ont of alinement with the slits O" in said cap C.

For the purpose of holding the cap C in any desired position relative to the ejector B, I use a suitable locking or holding device interposed between said parts, which may be either positive or frictional, and for this pur.

IOO

pose I have represented in the drawings a yielding frctional spring D, secured, preferably, to the part B and pressing against the part C, as fully represented in Figs. I and 6.

Having thus fully described the nature, construction, and operation of my invention, I Wish to secure by Letters `Patent and claim- 1. In a hose-nozzle a pipe having attached to its end an ejector having one or more slits combined with a rotating adjustable cap mounted on said ejector and having transverse slits or notches adapted to be brought in or out of alinement with the ejector-slits substantially as and for the purpose set forth.

2. In a hose-nozzle a pipe having attached to its end an ejector having one or more slits combined with a rotary adjustable cap mounted on said ejector and having transverse slits or notches adapted to be brought in or out of alinelnent with said ejector-slits, and having one or more slits or notches for throwing a sheet or sheets of water to one Aside of the ejector substantially as and for the purpose set forth.

In a hose-nozzle a pipe having attached to its end a slitted ejector combined with a laterally or radially slitted adjustable cap and a suitable locking or holding device for holding the parts in their proper adjusted positions substantially as and for the purpose set forth.

In testimony whereof I have signed myv name to this specification, in the presence of two subscribing witnesses, on this 18th day of April, A. D. 1896.
