This` invention relates to a portable-coupling for use in city fire departments; and the purpose of theinvention is'to provide a means by lwhich aftera hose-wagon on varriving at y theiire has had its hose connected to the source of wateresupply-'say a water-pressure iireplugand is playing on the iire'a steam lire'- engine on arriving maybe connected with'the same source of water-supply 'and may play on the lire through the saine hose already soco'nnected without disconnecting the hose con tion is toaccornplish this new result.

Toithis end my invention consists, essensuction-pipe and engine jdischargehosewith tia1ly,1ofa` coupling adapted for connectiong-4 i say with' the fire-plug` for connection withx the hose, anolforA 'connection with the engine g suitablevalve or cut-oliiy devices,` alll as vhere-` inafter more fully described, and particularly pointed out in tliegiclairns.

` Thejletter A designates. theportable coup ling generally, the saine'consistingv ofjone or more sections, as may be desired. In the 'present instance, for convenienceot' manufac-- ture, two sections B and C are used. sectionsv are-interconnected by means ofwel screw-tlire'adD and `band D. Section B is fr ny coupling, valineoi" hose, andthe pump'of- Aa steam fire-engine connected tcniy coupling ThesewA adapted forconnection witli'thesource of watersuppl.y'-say a fire-plug containing. water under pressure-andfor that purposeis pro:-

vided with' any approvedforrn of` threaded g ring E. The section B isvfurther. providedy ywithva cut-off F, adapted to be operated'by the application ofa'suitable vtool, toits pro.

jecting stemGr, as particularly seen infFi'gs. "1 and 3.v i As shown in Fig. 2, thecut-off 'stands in position to allow thewater to pass byitspressure from the ii re-pl ug through the coupling and `thence into andalong the line of hose H, assee'n in Fig. 5, andwhicli hose is connected' to the section C at Ii'by the usual means. vThe section B is further provided 4with a branch .1.. adapted, through atlireaded part`K, to be-connected with the engine suction-pipe L, as 'also' suggested Vbyljig. 5. The cut-off F stands across `the branch Jin what` IOO might be calledtlie"nor'inalv positionff--that is to'say, when'y the water is playing directly 'through-the coupling; but this cut-oli' is adapted to be turned so that itwill stand across" 'the passage ofthe coupling atthe point M,"

as shown in dotted lines in Fig. 2, in whichI position of the cut-off the water will pass into the branch J' and thence to the suction-pipe of the engine. To limit the movements of the cut-off, so 'that it will stand in either of the two positions described when turned to either limit. I provide a stud N on the outer wall of the coupling and provideacap O, with lugs P and Q.` When the lug P is in contact with the stud N, the water will'pass straight through the coupling; but when the lug Q is in contact with the stud N the water will pass out through the branch J. The cut-off F is tapered and is drawn and held in place in its seat by means of the cap O bearing upon the ring O', which in turn rests upon the coupling-casing, and by the threaded stud Q and nut R. The end of the cut-off has a square boss F, which fits within a correspondingly-v shaped socket O of the cap O, so that when the cut-ofi1 is turned the cap will turn with it and bring its lugs P and Q; respectively, into contact with the stud N. This is one mode of constructing the cut-off; but it may be departed from without departing from the invention itself.

The section C has a branch R, which connects with the discharge-hose of the engine through any approved connection, such as the threaded ring T. In this section there is located a valve U, pivoted at V, and when in the'normal or closed position, as shown in Fig. 2, it rests on a seat W. A cushion or gasket X is held to the valve proper by means of a plate Yand a screw Z. This valve serves the oce of preventing the water from fiowing into the branch R before the engine begins to act; but when the water begins to enter through the branch from the dischargehose S then the valve U opens until it nally swings against the stop a.

Having described the construction of my coupling in respect to the form selected for illustration, I will now set forth the mode of operation and manner of using the device. The coupling will generally be carried by the hose-wagon of a fire department and will be normally attached on the end of the hose. On arrival at the fire the crew willattach this coupling to, say, a water-pressure tire-plug, as seen in Fig. 5. They will then run out their hose and form a line, as suggested at H in Fig. 5. The normal position of the cut-ofi' F being that shown in Fig. 2 and also the normal position of the valve U being that shown in such figure, there is nothing for the crew to do but to turn the water on in the fire-plug, when it will instantly pass through the coupling and into the line of hose. The reason for the coupling being carried most usually by the hose-Wagon is that the hose-wagon usually reaches the lire ahead of the engine, because it is lighter and the horses can run faster with it. When the engine arrives, the crew immediately connects the suction-pipe L with the branch J of my coupling and at the same time connects the discharge-hose S with the branch R ofthe coupling. The engine is then put into action, and as it starts up the cuto F is turned quickly to the position shown in dotted lines in Fig. 2 or is turned more or less into such position, usually wholly to such position. The effect is to divert the Water through the branch J, or to partly so divertit, according to the extreme to which the cut-off is turned and to thus supply the engine with water. The action is so quick that in either case there is no interruption in the iiow of the stream through the hose, since the momentum of the water at the time the cut-off is manipulated is such as to keep up the stream for the mere instant occupied in diverting the water through the engine. It will be seen also that during the coupling-of the engine suction-pipe and discharge-hose to my coupling there is no interruption in the play of the water. It will further be seen that the same` hose which the hose-wagon crew connected with the fire-plug and were using when the engine arrived is utilized after the engine goes into action. Incidentally this not only has the advantages above referred to, but avoids the use of additional hose and saves the cost of purchasing and carrying the same, as well as the time in runningI it out during the fire. Thus the several advantages and features of utility of my coupling will be fully understood in addition to its construction and simplicity.

I have shown the sections B and C as directly connected together; but .it is obvious that without departing from my invention they might in practice be otherwise related or that the distance between the two sections might be greater-than here shown. It will further be understood that the particular type of cut-off and valve may be changed or varied without departing from my invention and that whether the coupling is made in two sections or more or only one is not material. It will also be understood that in use section B of my coupling might be left on the lireplug, while section C could be carried on the hose or with the hose-wagon or possibly in some cases with the engine and that on arriving at the plug the connection would be made between the two sections instead of as here illustrated and described, where the connection is made between section B and the plug. This is merely referred to as a possible though not so advantageous a system of use of my device. I would further state that while it is preferred in practice to apply the coupling to the source of water-'supply directly, still there may be more or less distance between the coupling and suph supply as if a section of hose extended from the immediate source of supply `to the coupling instead of screwing the coupling directly to the fire-plug.
