JOHN EGLESTON, OFWESTFIELD, MASSACHUSETTS.

FTRE-EXTINGUISHING APPARATUS.

Specification of Letters Patent.

Patented Mar. 2?, 191?.

Application filed March 21, 1916. Serial No. 85,721.

To all whom it may concern:

.Be it known that 1, JOHN EGLESTON, a citizen of the United States of America, and resident of Westfield, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in Fire-Extinguishing Apparatuses of which the following is a full, clear, and exact description. I

This invention relates to improvements in fire extinguishing apparatuses, and is more especially designed for use in residences, al-

I though available and applicable for use in office buildings and other situations.

The apparatus comprises a casing or cabinet adapted to receive therein a hose, in folded or other compact form, a valve body in said casing having an inlet connection member and an outlet member, and a valve in said body for closing the inlet having a slidable stem, a hose connected to the outlet member, and a device for exerting a valve opening draft on the valve stem, operable through a connection with the hose so that when the hose is unfolded and entirely run out the draft action exerted by the hose will effect the opening of the valve to turn on the water for its discharge through the hose.

The apparatus, furthermore, includes means for retaining the hose in its compact, folded condition within the casing.

Other features of advantage comprised in the apparatus will be hereinafter rendered manifest.

The invention is described in conjunction with the accompanying drawings and is set forth in the claims.

In the drawings Figure 1 is a front view of the fire extinguisher,the hinged front or cover of the casing being indicated as swung open.

Fig. 2 is a sectional elevation as taken on substantially the line 22, Fig. 1. I

Fig. 3 is a cross section, on a larger scale, as taken on the line 33, Fig. 1.

Fig. 4 is a vertical sectional view on a larger scale, through a part of the apparatus as taken on line M, Fig. 1.

In the drawings, A represents the cabinet or casing, which may be regarded as the supporting frame for the apparatus, and for which a hinged door A is provided at the front for the closing thereof.

This casing or cabinet is intended usually to be built into the wall in a house.

Within the casing, at one side thereof, is

a .valve body B having inlet connection member a and outlet connection member I).

64 represents the water supply pipe coupled to the inlet member of the valve body, and C represents the hose coupled to the outlet member of the valve body.

(Z represents the valve for closing against the valve seat 0 in the chambered valve body and for closing the passage of the water through the valve.

The stem of the valve is slidable through a gland or bonnet g, and is made in screw united sections f and f for practicability of assemblage.

The valve is made with a member (P, which when the valve is open and subject to pressure of the water passing through the valve body and the hose, seats against the packing (Z of the gland and prevents the leakage of water to the exterior of the valve.

A toggle is employed for controlling the condition of the slidable valve stem and valve carried thereby, the link member 7% thereof being permanently connected by pivot k to the outer end section of the valve stem, while the link member 1' has one end thereof, by pivot j, connected to the link It, and has its other end permanently connected by pivot i to a bracket or fixture secured to, or formed as an integral part of, the casmg.

One of the link members, here shown as the one 2', is provided with an angular projection is, terminating in a transverse foot 70 The link members of the toggle normally are as shown in full lines in Fig. 2, that is practically straightened, although the pivot 9 is at a point a little inside of the line between the pivots h and 2' D represents a flexible connection, one end of which is attached to a part of the hose adjacent the valve, while the other end thereof is attached to a suitable part of one of the toggle link members, and this flexible connection, which may be a wire cable, cord or chain, is intermediately guided so that when draft is exerted thereon through the hose with which it is connected, it will exert a force substantially atright angles to the length of the toggle and in a direction to break the toggle, and exert a valve opening draft on the valve stem,-the angular or broken relation of the toggle members being represented by dotted lines in Fig. 2.

The hose is represented in Fig. 1 as being slack or having loops or partial folds there in between the point of attachment of the flexible connection D therewith and its point of connection with the inlet member I) of the valve.

A part of the hose located a few inches distant from its connection with the valve, and at which the flexible connection I) is attached, is provided with a metallic appliance for preventing the collapse of the hose at this point and to afford a practical means of attachment of the cable D to the hose.

This appliance, as shown, consists of a pair of opposite transversely curved plates m m to embrace the hose, and a rigid frame or split ring 0 to clamp the plates at by the hose.

One of the plates m has a radially projecting stud m by which the eye member 3) of the end of the cable D engages,p representing a clamping nut for confining said eye member in its engagement wlth the stud.

The cable D extends from its connection with the hose through an eye member or circularly apertured lug g to one side of the valve body, and somewhat distant from the back or base of the casing.

The cable D thence passes around a sheave '1" so as to be guided more or less nearly parallel with, or along the length of, the casing.

The end portion of the cable ad acen t the link member 2' of the toggle has a guiding engagement around another sheave r so 7 that from the location of such sheave r and its point of attachment with the foot member of the link member, the draft to be; exerted through the cable will be in a direction at about right angles to the length of the toggle link member i and in a manner 7 most effective to break the toggle.

An intermediate eye member or guide 8 is shown as provided,it however, to be understood, that so long as suitable guides for the cable are provided, the same need not necessarily be exactly as shown.

' The hose in Fig. 1 is shown as folded up, compactly disposed in a'multiplicity of reversed folds and retained by a double set of resilient clips with which the casing is in ternally provided, each set consisting of coils t of spring wire preferably having a tubular rubber covering t and having the bases thereof confined between a bar u secured across the back or base of the casing, and a clamping bar u ,the last referred to features being represented in the enlarged view, Fig. 4'. V

The coils or loops may be elongated so as to engage and receive the folds of an unusually long hose in a double tier, as occasion may render desirable.

In case of emergency, the cover or door of the cabinet is swung open, the nozzle end of portion of the hose is becoming straightened out, the exertion of the required draft on the cable for the automatic valve opening action.

Inasmuch as the pressure of the water in the taut portion of the hose adjacent the valve is usually so great as to render it impossible to flex such portion of the hose so as to straighten the toggle to close the valve and shut off the water, the cable is disconnected from its connection with the hose by unscrewing the nut 27 from the stud m After the hose shall have become dried and is replaced in the casing in its folded disposition, the connection of the eye member of the cable D is again made with the non-collapsible appliance m, 0, and to leave the apparatus in readiness for its utilization when occasion therefor requires.

While this apparatus is primarily designed as a fire extinguishing apparatus, the hose may be employed for the discharge or distribution of water for other purposes.

Various changes from the constructions comprised in this apparatus may be made without departing from my invention or sacrificing any of the advantages thereof.

I claim 1. In a fire extinguishing apparatus, in combination, a supporting frame, a valve body in said frame having an inlet connection member, and an outlet member, and a valve in said body for closing the inlet having a slidable stem, a hose connected to the outlet member, a toggle having one link member thereof pivoted to the valve stem and having the other link member thereof pivoted to a fixed part of said frame, and adapted in its straightened condition to hold the valve closed, the hose having, to be embraced thereby, a pair of opposite curved plates and a rigid frame encircling said plates at a suitable distance from the point of connection of the hose with the valve, said embracing device having a threaded stud, and the hose being normally slack between said embracing device and the valve, a flexible connection having one end attached to a link member of the toggle, and having an eye at its opposite end adapted to detachably engage said stud, and a nut screw engaging said stud to confine the eye portion of the flexible connection in its engagement thereon.

2. In a fire extinguishing apparatus, in combination, a supporting frame made in the form of a forwardly opening casing, a valve body located within and near one end of the casing, adjacent the back of the latter, having an inlet connection member and an out-' let member, and a water supply pipe leading through the end of the casing and connected with the inlet member, a valve in said body for closing the inlet, said valve having a stem slidable in a direction along the length of the casing, a hose connected to the outlet member, a toggle having one link member thereof permanently pivoted to the valve stem, and having the other link member thereof pivoted to a fixed part in the casing and adapted in its straightened condition to hold the valve closed, a flexible connection attached to a part of the hose adjacent the valve outlet member, a ring eye supported by the casing at a location adjacent the valve outlet member and outwardly beyond the back of the casing, a guiding sheave in the casing inwardly opposite said ring eye, another guiding sheave in the casing located adjacent, but outwardly beyond the pivot connecting the toggl e members, said flexible connection being guided from its connection with the hose through said ring eye, inwardly partially around the first named sheave, and to and partially around the second named sheave and extended from the latter in a direction angularly to the length of the toggle members and having a connection with one of such members.
