FIRE-EXTINGUISHER.

SPECIFICATION forming part of Letters Patent No. 589,202, dated August 31, 1897. Application filed May 3l, 1895. Serial No. 551,074. (No model.)

To all whom t may concern:

a citizen of the United States, residing in the city of New York, in the county and State of New York, have invented certainnew and useful Improvements in Fire-Extinguishers,

of which the following is a full, clear, and

exact description, reference being had to thev accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.

My invention relates to that class of reextinguishers which may be carried from place to place for use and in which liquids and chemicals are used, which are designed to be left separated when the extinguisher is not in use and to be united to perform their proper functions when it becomes necessary to employ the extinguisher to suppress a lire. Usually a strong soda solution is employed, which is kept in the tank or receptacle constituting'the 4extinguisher, and in the saine tank a vessel containing strong acid is disposed, and the apparatus is rendered effective for use by mixing the acid and soda solution and thereby generating a gas by means of which the contents of the extinguisher are forced out throughahose and impelled upon the re. In these devices great difticultiesl have been met in properly arranging a vessel containing the acid within the tank or receptacle. should be made of glass, that it should be sealed when the extinguisher is not in use, that its contents should be easily and certainly released when it is desired to use the extinguisher, and that it should be of such structure as to be readily and conveniently replaced in case of breakage.

The object of my invention is an acid holding and discharging device which will safely contain the acid, in which neither the vessel nor any part of it is to be broken in order to discharge the acid, which is so constructed that the sealing device will certainly be removed from the oriice of the acid-holding vessel,'and in which an ordinary bottle is to employed, which can be readily replaced at any drug-store in case it should be broken and the extinguisher at once recharged;

To enable others skilled inthe art to make It is very desirable that thisvesselY t land use the same, I will now describe its con- Be 1t known that I, BENJAMIN S. BROWN,

the acid-bottle contained in its cage suspended thereto, partly in section. Fig. fshows the acid-bottle and certain parts reversed as they appear when the acid is to be discharged. Fig. 4 is a view from the line a: an of Fig. 2,

looking downward. Fig. 5 is a view from the line z z of Fig. 2, looking downward, the acidbottle and weight removed to show the parts more clearly. Fig. 6 illustrates an example of my invention in which the stopple Gr is prolonged to form a guide into the orifice of the acid-bottle. Fig. 7 is a perspective View of parts ofthe form of device shown in Fig. 6. Figs. 5, 6, and 7 are drawn to a scale larger than the other figures. y

Similar letters of reference indicate like parts in all the drawings.

A represents one of the ordinary fire-extinguishing vessels or tanks, which is to be provided with a suitable hose B, connected to dischargethe contents and provided with a nozzle B. The extinguishing vessel has a vscrew-threaded neck adapted to receive a closing-cap C, to which the acid vessel, with Iits accompanying devices of my invention, may be secured in any convenient manner.

The acid vessel readily adapted for use in my invention may consist of an ordinary round bottle D-saya four, six, or eight ounce bottle-such as is usually in stock at drug stores.

In the example of my invention figured in the drawings the acid vessel D is shown disposed in a cage consisting of a bar I-I, which is bent to have a leg H H on each side of the bottle D and a cross portion H2 at the top, connecting the two legs II H. The cross part at the top may be soldered or otherwise secured to the cap C. In Figs. l and 2 the same is shown attached to the cap C by two auxiliary strips I I, which pass around it, and being soldered to the cap C hold it firmly in place there. At the lower ends of the legs H H' feet H8 II3 are formed, by means of which the legs H H' are firmly secured to a IOO ring M, which is made of a size to allow the the bottle D to pass through it from beneath until it reaches a point where its shoulder impinges against a ring 7i,which has an opening of such size as to prevent the further passage upward of the bottle D. This ring h' is secured to the legs H H in any convenient manner. A disk N is attached at a suitable point to the ring M by a pivot p, as shown in Fig. 1, by means of which the disk N can be turned out of the way of the opening in the ring M to permit the bottle to be passed through the ring M', between the legs H1 H, and against the ring h', and when the bottle has been passed into place the disk is turned upon its pivot p to close the opening and support the bottle in position, a suitable clamp O, Fig.,l, supporting the disk N at a point opposite tothe pin p.

For sealing the said bottle D a stopple Gis provided. This consists of a portion which projects into the orifice of the bottle a reduced portion which is adapted to take and retain a rubber disk F, having a. hole in the center, and an enlarged portion adapted to rest on the rubber disk and hold it down upon the neck of the bottle and seal the same, as clearly shown in Figs. l and 2. ln order to guide the stopple G upon and into the neck of the bottle, a guide portion is provided, one form of which may conveniently consist of a piece, as K, attached in any convenient manner to the top of the stopple G.4 This guidepiece has projections 7o k, which move in slots h h of the legs H H and always hold the stopple G in line with the neck ot the bottle D.

For the purpose of holding the stopple and rubber disk to the neck of the bottle to seal the same I have disposed a suitable device which performs that office by gravity. This consists of a piece forming a` pair of legs J J and an u pperconnection J, to which the guide K and stopple G are connected. At the end of the legs J J the feet m m are provided., and the arrangement of the parts is, such that when the stopple is in the bottle the guide K passes between the legs H H', and the projections k k of the guide pass through and beyond the slots h h, and over the stopple'and guide-piece K the part J crosses at right angles to the upper part H2, so that the bottle D is disposed between the four legs H Il and J J, as clearly shown in Fig. 4.

To weigh down the stopple upon the disk F, a weight L is provided, which may be in the form of a metal ring consisting of two parts, which can be hinged together, as shown at Z in Fig. 4, and opened to be clasped around the legs H Il J J, and closed around them and held together by a suitable spring Z', Fig. 4. This weight rests upon the feet m m of the legs J J, as clearly shown in Fig. 4, whereby the weight is suspended upon the stopple G and holds the same against the rub.- ber disk F by gravity, and thereby the bottle is sealed, which prevents weakening of the acid by taking up moisture from the water in the extinguisher-tank.

As these extinguishers are frequently placed in position for a long time without use, by reason of which the working parts are liable to corrode and stick together, it is necessary to provide eiiicient means for unclosing the bottle when the acid is to be mixed with the solution in the tank. The liability of a rubber seal to stick to the neck of a bottle when held in place for any length of time is well known, and until my invention, described herein, it has not been practicable to use sucha sealing device, although no better device is known for that purpose. For this purpose the weight L is. utilized toperforrna percussive otlice, the reextinguisher isreversed,Y which causes the parts toassume the position shown in Fig. 3, the weight L slides down the legs H H J J, striking theiends 7a 7a of the guide K in its. downward path, and thereby the stopple G and disk F are forcibly driven away from the orifice of the bottle..

Another example of my invention is shown in the drawings in Figs, 6 and 7,. In thisexample of my invention legs H4, correspond-v ing to the legs I-I, but without the slot haatte provided and the guide K is. dispensed with. A guide for the stopple G is. termed by pro-Y longing the same with a stem, asp/which re.- mains within the orifice of the bottle when the same is reversed. The Weight-carryingy part of this example of my invention consists of legs J3, corresponding to theV legs J and having a. cross-piece J? at the topcorrespond'- ing to the cross-piece J', but near the upper part of the weight-carrying legs projections j are provided, against which the weight L strikes when the bottle is. reversed. This projection j may be readily made by stamping out apart of each leg J3 andv turning it outward, as shown in Fig. 7,` or a screw or other form of detent may beA attached to each of the legs J 3 inthe pathl of the'y weight to ref ceive the'impactof the weight when the'. bottle is reversed,` as shown in Fig.V 6.

The weight may have openings o o formedV through it,V which will increase the space for the commingling of the acid and solution, if desired.

The metallic parts may be formed of aluminium, if desired, which is a metal not liable to corrode, althoughv I have found that copper will answer the purpose very well. The weight L may be cheaply cast in` iron, or lead,` and the stopple can also be madeof lead. The sealing-disk F` may be conven-A iently made of rubber;

The operation of the device is as follows.: The cap C of the extinguisher is takenof, and therewith the cage andacid-bottle. The liquid solution is poured into the. cylinder or tank. The bottom N ot the cage is swung away and the acid-bottle D taken out andlled to near'the top. It is then inserted into the cage through the ring M, and the bottom N is adjusted to hold it in place. The cap ICO IIO

C, with its cage, is then screwed back onto the extinguisher, and the same is put asidev Abottom and replenished With acid. Liquid solution is again put into the tank, acidinto the bottle, Which is put into its cage, the bottom closed, the cap C fastened into position, and the device is again ready for use. It Will be noted, furthermore, that as the stopple is always in line With the opening of the bottle the discharge of the acid can readily be stopped, if desired, by simply reversing the position ofthe extinguisher, when the Weight Will act to draw down the stopple and sealing device upon the oriiice of the bottle.

It Will be seen from the description that there is no part of this device which is designed to be broken or destroyed by the ordinaryuse for which it is intended; that in using it there are no pieces of glass or other broken material to Work into the hose or hoseopening and obstruct free passage therein; that the only part which can be broken is a common round bottle, which if broken by accident can be replaced at any drug-store and the device rendered as effective as it was before. Where a peculiar seal or vessel or bottle is designed to be broken or is broken by accident, it often happens that it cannot be replaced at once, but must be supplied from a distance, or it may not be practicable to replace at all if the particular manufacturer has changed his patterns or gone out of business.

It will be evident that my invention can be carried out by the use of other .forms of Weights, projections, cages, and parts coacting to suspend a Weight. upon a stopple provided With a sealing part and adjusting the Weight to hold the stopple in place by gravity and then to release the stopple percussively by striking upon some part connected With `it, when the position of the acid-bottle is reversed, and therefore I do notlimit myself to the forms of the parts shown; but,

Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, is-
