Application filed November 1, 1916. serial No. 128,922.

To all whom it may concern:

Be it known that I, EDWARD E. FEnGUsoN,

a citizen of. the United States, residing at- Portsmouth, in" the county of Norfolk and State of Virginia, have invented certain new and useful Improvements in Combined Fire- Alarm Boxes and Hydrants; and I do hereby declare the followin to be a full, clear,

and exact description 0 the invention, such as will enable others skilled in the .art to which it appertains to make and use the" same.

The present invention relates to improve-. ments in fire alarm and water distribution systems, and consists more particularly in an improved combined fire alarm box and by .drant.

It is a primary object of the present invent-ion to provide a hose mounted in connection with a fire alarm box in such-man.- ner that when the nozzle of the hose is removed an alarm will be turned in, and when the hose is removed from a support, provided near the alarm box to receive the same, the water supply will be turned 'on, so that a single person, detecting a fire may have the convenient means at hand of automatically turning in the alarm and in theratus constructed in accordance with the present invention.

Fig.2 is a side elevational view of the alarmb'ox.

Fig. 3 is a front elevation of the alarm box with the door open, and showing the alarm setting lever in the potential position before the alarm has been turned in.

Fig. 4 isa similar view of the alarm box,

- illustrating the alarm lever as having been released.

Fig. 5 is an enlarged cross sectional viewthrough the service-pipe and drain.

Fig. 6 is an enlarged fragmentary view of v the upper end of the service valvelever,

Fig. 7 is a similar view at right angles to Fig. 6; and

Fig. 8 is a sectional view taken on the line 88 in Fig.7. I Referring more particularly, to the drawmgs, 1 des gnates a service-pipe connected to a; 'watenmain in the usual manner. A hose 2 is held by a suitable union to the service-pipe land is folded and placed upon a support 3 above, or near a fire alarm box 4. The hose nozzle is indicated at 5.

On the nozzle 5 is a projection 6 having an inclined lower edge 7, for the purpose of entering an opening8 in one side wall of the alarm box 4.2 As clearly seen from Fig. 3, when the projection 6 is placed within'the opening 8 the nozzle 5 is supported thereby and is prevented from accidentally jarring therefrom by the inclined lower edge 7. The alarm setting lever 9 within the box 4, is adapted'to engage the projection 6, which lies in the path thereof, and holds said lever 9 suspended in the potential position in readiness to drop bygravity or spring when the nozzle 5, and projection 6 are removed,

. and act in a well known manner to turn in the general. alarm.

Fig. 4 shows the fallen position of the alarm setting lever 9 after the nozzle 5 and projection 6 have been removed; and when in such fallen position the lever 9 carries a block 10 down therewith to close the opening 8 and prevent the reentering of the proalarm box 4 therefore furnishes a suitable support from which the .nozzle 5 maybe suspended, and from which it may not be stolen without sending in an alarm.

In the service pipe 1 is included a valve casing 11 having a gate or other valve 12 therein. The valve 12 is hung on a suitable shaft 13 projecting from the casing 11, and connected to be oscillated by a lever 14. A link 15 connects the lever 14 with a second lever 16 in operative'relation to a valve 17 in a drain pipe 18, which is connected tothe as, for instance, the service valve 12 is shown in this figure to be closed, shutting oif the water supply, ,while the drain valve 17/ 1s open, permitting the water from the'hose 2 i of the longitudinal axis of said lever. The

opening 19 is for the purpose of receiving a tip 21 on a flexible connection 22, such as a cord, rope, or the like, there being a cap 23 forming a shoulder for engaging the wall of the lever 14 adjacent the openin 19, and preventing the tip 21 from passing therethrough. In this tip 21 is an annular groove 24 having an abrupt or perpendicular wall 25 and an inclined or conical 'wall 26. A. pawl 27 is fitted to slide at the base of the longitudinal passage 20 and is'limited in its downward movement by a shoulder 28 formed between said passage 20. andJ a socket 29 in which is placed a coil spring 30 for yieldingly urging the pawl 27 upwardly. The pawl 27 has, at its upper end, a tooth '31 shaped with an abrupt edge 32 and an inclined edge 33 formed complementary to the V groove 24 in the tip 21, and fitting the same snugly, as clearly illustrated in Fig, 8. In this position the tip 21 is locked in place by the pawl 27, and can be withdrawn from the opening 19 only when said pawl is retracted in opposition to the spring 30.

The withdrawal of the pawl 27 from engagement with the tip 21 is automatically accomplished by means of a finger. 34 pivoted at 35 on the lever 14 and carrying a screw,

pin, 'or other device 36, which engages through a vertically elongated slot 37 in the lever 14, and is connected in any suitable manner through the opening 38 in said pawl 27. This trip finger 34, as disclosed to advantage in Fig. 1, lies in the path of a lug 39 on the upper end of a stationary arm 40. This arm .40 is connected, in any suitable manner, to the service-pipe 1, or other fixed support; the lug 39 thereon forming a stop for the lever 14 and acting, when struck by the finger 34, .to swing the latter about its pivotal connection 35,- thereby moving the connecting pawl 27 downwardly in the passage -20 in a manner to release the tooth .31 thereon from engagement with the annular groove 24 in the tip 21. In such position the .tip may be withdrawn from the slot 19, thus releasing the. connection 22.

As shown in Fig. 1,. on the arm 40 is a pulley block 41 through which engages the flexible connection 22. The opposite end of the flexible connection 22 is coupled to the hose 2 as by the means shown at 42 in Fig.

in the general alarm.

1; although other means maybe employed without departing from the present invention..

The operation of the invention is carried on substantially as follows:

The several parts are normally in the positionshown in Fig. 1, where the nozzle 5 is suspended from the alarm box '4 and, the 'hose'rests on the support 3, with the service valve 12 closed, as indicated in Fig. 5, and the drain valve 17 open, allowing any water in the hose to be discharged through the drain 18. Y

In case of fire the nozzle 5 is grasped and lifted so that the notch or inclined lower edge 7 of the projection '6 maybe withdrawn through the opening 8 in' the alarm box 4. I When the projection 6 is so withdrawn, the

lever 9 will drop from the position shown in Fig. 3 to that shown in Fig. 4, and will actuate any suitable mechanism for turning I When the nozzle 5 has been thus released from the alarm box 4, the hose 2 will be drawn down from the support 3, and when fully removed therefrom I will drop by gravity tothe ground, thereby :pulling upon the flexible connection 22 which will swing the lever 14 over, opening the service valve 12 and, through the'link 15 and lever. 16,

simultaneously closing the drain valve 17, so

as not to permit the escape of the waterflowin throu h the service-pipe 1 to the hose 2. en t e lever 14 is thus swung over, the finger 34 will strike the lug 39 on the arm 40 and will move said finger about the pivot 35, thus operating, as above described, to trip the reciprocating pawl 27 and permit the'escape from the opening 19 of the tip 21 on the flexible connection 22. The flexible connection 22, together with the tip 21, ma thereby be drawn through the pulley bloc 41 and fall down with the hose 2; while the weight of the valve-operated parts will maintain the same in actuated position with the service-pipe-1 open and the drain 18 closed. Water'will thus be supplied to the hose 2 until the valve mechanism is returned by hand to a position closing the servicepipe and opening the drain. This manual return of the valves to theirvnormal positions is accomplished after the fire has been extinguished, and subsequently the hose is replaced on the support 3 which is elevated above the service-pipe 1, and from which any water that mayremain therein will be discharged through the-drain 18. After the hose has been replaced on the support 3, the flexible connection 22 is again inserted through the pulley block 41,.and the tip 21 re'ngaged with thepawl 27 in the opening 19.-

1 After the nozzle 5 is suspended from the alarm box by lifting the lever 9 from the pos1tion shown in Fig. 4 to the raised potential position shown in Fig. 3, the apparatus is again in the initial position in readi ness for subsequent operation. It is obvious that those skilled in the art mayvary the details of construction and arrangements of parts Without departing from the spirit of my invention, and therefore I do not wish to be limited to such features except as may be required by the claims.
