` To all whom t may concern.'

Be it known that .I WILLIAM RICH, a citizen of the United states of America, and resident of Liverpool, in the county of Lancaster, England, have invented new and useful Improvements 4in Apparatus for Indicating Fires in Compartments at a Distance, of Whichthe following is a specification.

This invention has reference to systems and apparatus for detecting fire in compartments or rooms or spaces, at a distance, from a place of detection or observation; and it relates more particularly to that type of system in which pipes extend between separate compartments or rooms, and the said place of detection or observation; and through which air is continuously, or at 1n- 'tervals, drawn or caused to pass from the separate compartments or rooms, so that if a fire breaks out in any one of the compartments o r rooms, smoke is automatically drawn or caused to How to theplace of observation, and it is made known that a lire exists in that compartment or room; and when it is so ascertained, steam is adapted to be transmitted through that particular smoke conveying and indicating tube to the compartment or room, and the fire smothered.

The object of the present invention is to provide improvements in connection with systems and apparatus of fire detection and extinction by which certain objections hereinafter referred to are obviated, and the system as a whole, is improved.'

The system Ias hitherto arranged and worked, has been open to objection in some cases as applied to and used on ships, in connection with which it is very advantageous. The objections were largely that the place of detection and observation. of the system was located in a Wheelhouse or similar house of the shipwhich, especially in large ships, isv

occupied by an officer in charge, so that if a fire broke out, it could be immediatelyseen here by the oflicer'in charge; but inasmuch as in 'this observation apparatus, inwhich the terminals of the pipes are placed, an

electric motory and fans are used, the noisel of them is found disturbing to the oicer; and the further disadvantage is, especially in large ships, that the apparatus is necessa- .rily very 4large, and occupies therefore a large space, whether built in one large one or in several parts, say placed slde by side; and this latter applies, whether the appawhatever room it was placed in'.

Accordlng to this invention, the pipe `termina1 station case, with its air fan and electric motor, -do not constitute the main or chlef observation or detecting means; but

- ratus were placed in the wheel-house, or

the chief or main detecting means and obwill be under the observation of an oiicer or other authority; and in this part of the apparatus, the existence of smoke is made known and observed. The'pipe terminal station boxes-which may be conveniently termed sub-stations-a1e distributed in different parts ofthe ship, at which they may be conveniently or advantageously located; and they also serve as means of observing the condition of the various holds or rooms of the ship, and a means of detecting fire.

The main or terminal detecting and observing station apparatus is without moving parts and silent, and occupies relatively only very smallspace. In all cases, this terminal detecting apparatus will be such that the presence of the smoke will be seen or indicated by it; and preferably this is effected by the employment of a chemical indicating means, by which the presence of smoke or products of combustion will act upon a chemical which will change color, and so give an indication of its presence. Ad'- vantageOuSly, this change of -color indicai presence of the carbon dioXid which usually accompanies the smoke, which is passed to the liquid or lime-Water through the pipe from the sub-station pipe terminal case. Each terminal pipe sub-station will, in most cases, be connected upI with a detecting and observation appliance in the terminal station; so that if there are three sub-station cases, there will be three detecting and observation instruments or appliances in the main terminal station. l

The invention will be further described with the aid of the accompanying drawings which illustrate it. In the example shown there are three sub-,station apparatus shown, operating in connection with a single terminal detecting and observation apparatus;

and it will be assumed that this sub-station apparatus will be disposed in different parts of the ship where it may be conveniently placed, seen, attended to, and used, and where the noise of the motor fan is not objectionable or disturbing, and where the steam connections can be conveniently lald.

Referring to the drawings a1, a2, a3, represent the sub-station boxes or cases, each having in the lower part of it, the ends of the tubes b which extend between the case and different compartments of the ship, and each of the pipe terminals will have a fitting, to which the union of a hose-pipe connected with the source of supply of steam is connected; while inthe upper part it is provided with a fan c which is electrically driven, either continuously or intermittently; its starting and stopping being controlled by a suitable clock which opens and closes the circuit to the motor of the fan.

The terminal station boX or case is marked e, and each of the instruments within it is connected with a sub-station case by a pipe cl, the end of which at the sub-station enters the pipe f, which conducts the surplus air or air and smoke from the fan or propeller c away to a place of discharge. The lower ends of the pipes d are open, and project into the pipes f, so that any smoke that passes into any of the cases 'a from any of the pipes b, will be drawn by the fan c, and forced by way of the pipe d up into the instrument in the case e; and this will be detected and indicated.

The sub-station cases a1, a2, a3, have doors 7c on them, and the part m, of the doors,

opposite the mouths of the pipes b, to which the steam supply pipe will be coupled as stated, will be glazed to form a window through which, in case of fire, smoke passing from any of the pipes, will be seen; so'that the sub-stations in themselvesconstitute additional detecting and observation means.

The detection and observation indicating means in the terminal station e, consist of glass or other transparent vessels b-or they may be provided with an opening for observation-having in them lime Water, or other chemical which will change l.in the presence of smoke or thev products'ofcombustion due to the'production' `of a White 'precipitate in the -colorless solution used;

' and into these vessels the bentv down'ends of the pipe d dip,A e,ir-tending leitherj'ust' over the liquid, or into it soithatth'e smoke or products of.con'ibustio'n'v passlng-up thel pipe d will act. upon the liquid and affect it and changeJ its color. The .vessels la, .canv

be filled withliquid through the funnels i, and can be emptied through the draw-off pipes j; while smoke andair passing into the vessels h can also pass away by the funnels i, the lower end of which ,lie above the level of the liquid. In use, if a fire breaks the fan c and forced into the pipe f, andy so into the lower open end of the pipe d, by which it will be conducted into the/vessel t of the detecting apparatus'e which is connected with this particular sub-static apparatus.

The smoke, in consequence of its contents of carbonio acid, makes the lime water contained in the vessel l1, milky; and the ofiicer in charge therefore sees that smoke has been drawn through the sub-station case a connected with this particular bottle or vessel h.

In consequence of this the sub-station case connected with this bottle or vessel is at once examined, and it can at once be ascer- Y tained in which compartment of| the ship a fire has broken out.

It will be seen that the whole'of the air is not driven through the pipe d, but only a portion of it, and that the remainder is discharged through the pipe f into the atmosphere. Upon the pipe f there may be usedl a suitable throttle or other'controlling valve or stopping device, which will be so arranged that the greater part of the air is driven into the open, and only enough air is driven through the pipe b that, if smoke is" present, a suiiicient quantity of smoke reaches the indicating vessel h to cause the reaction in the lime Water. p

' When the fire is extinguished, the lime water-which will be colored dark gray by. i

the smoke-is let out of the bottle k by means of the cock and the bottle is refilled -through the fiume i.
