FIRE-HYDRANT.

SPECIFICATION forming part of Letters Patent No. 468,782, dated February 16, 1892.

p. Application tiled-September 2, 1890. Serial No. 363,750. (No model.)

To a/ZZ whom it may concern:

Be it known that I, SIMON BRENTANO, of the city, county, and State of New York, have invented certain new and useful Improvements in Fire-Hydrants, of which the following is a specification.

This invention relates to that class of firehydrants wherein, as usually constructed,`

screw-caps are employed, the cover is separately unfastened, and the Water subsequently turned on; and the object of the invention is to. reduce to a minimum the delay attendant upon opening such hydrants and to save valuable time in connecting the hose to the hydrant and in turning on the water.

In general terms the invention consists in a lire-hydrant in which unthreaded outwardly-opening caps for the hose-nozzles are employed, together with a single locking and operating mechanism, by means of which a cap is iirst unlocked, the water admitted after the lapse of sufcient time for the hose to be connected. A second cap is then in turn unlocked for the connection of a second hose, and a valve is then subsequently opened for the passage of water through the nozzle, cooperating with the second cap.

The improvements are illustrated in the accompanying drawings, wherein- Figure 1 is a central vertical section of a hydrant containing the improvements. Fig. Eis a front elevation of the same, partly in section and broken away. Fig. 3 is a horizontal section in a plane indicated by the line 3 3 in'Fig. 1. Fig. 4 is a partial longitudinal section in a plane indicated by the line 4 4 in Fig. 1. Fig. 4 is a detail sectional view showing the locking-bolt on an enlarged scale. Fig. 5 is afragmentary vertical section showing a moditication of the interior valve which closes the outlet to one of the nozzles.

1 indicates aiire-hydrant having two screwthreaded ports or nozzles 2 and 3, as shown.V Any greater number of the nozzles may be provided, if desired.

Instead of the usual form' ot screw-cap which is ordinarily employed fitting over the hose-nozzle, (which consumes valuable time in the haste incident to a fire to unscrew, and which is also liable to become jammed or stuck by violence or by the changes in temperature,) unthreaded outwardly opening caps 4 are employed to cover the ports or nozzles 2 and 3, the caps being hinged to the under side of the ports, so as to swing down automatically upon being unlocked. It' desired, the caps may be hinged to swing laterally; but the downwardly-swinging caps are preferable.

Each cap 4 is formed with an upwardlyextending portion or lug 5, which, when the cap is closed, seats against a corresponding upwardly-extending projection 6 on the cooperating port. Formed in the upwardlyextending portion 5 is an L-shaped slot or passage-way 7, which registers with a slot or passage-Way 8 in the upwardly-extending projection 6.

`lVithin each of the slots 8 is located a lock` ingbolt 9, having a curved outer end 10 adapted to move laterally into the slot 7 in the lug 5 and so lock the cap 4 in its closed position. The width of the slots 7 and S is such that as the bolt therein is moved forward or retracted there will be room fr its lateral play in engaging or disengaging the outer angular end of the slot 7 as the bolt slides in the slot S.

The preferred shapes of the slots 7 and 8, and the preferred shape of the locking end 10 of the bolt 9, are shown in Fig. 4f. A somewhat moditied construction in these respects is shown in Fig. 4.

Each slot 8 communicates with the interior of a vertical casing 11, located on the hydrant above each port or nozzle, and the inner end of each bolt 9 is pivoted to a horizontallysliding bar 12, located within the casing. Each bar 12 is provided with a laterally and horizontally projecting pin 13, which engages an inclined slot or way 14, formed in the lower end of a vertically-movable bar 15, located in the casing 11.

Each of the bars 15 is guided between onev ot the sides of its casing 11 and guide-strips 16, and is formed with. aninclined slot or way 16 nearits upper end, which is engaged by a pin 17, extending laterallyfrom a horizontally-sliding bar 18 projecting through a passage-Way or aperture in the wall of the hydrant. This bar 18 is bolted to a ring 19, elnbracing an eccentric 19', which is carried by a vertical shaft or rod 20 within the hydrantcasing. rlhe two eccentrics are connected to the shaft by splines, so that the shaft can move vertically without moving the eccentrics with it. v

The shaft or rod 20, which is employed to operate the locking-bolts 9, the water-supply IOC ' or rod 2O as it is turned is also lowered or raised. The plug 22 is secured in place by a nut 23, and the upper projecting end of the shaft or rod 2O is formed with a wrench-boss 24 for the application of a key or wrench to operate the shaft.

Beneath the eccentrics 19 is located a stuffing-boX 25, through which the shaft 2O passes. The stuffing-box 25 is carried by a partition, which separates the watenchamber of the hydrant from the upper part. It will readily be seen that upon turning the shaft 2O so as to lower the same the eccentrics 19"'will also be turned and will act on the rings 19 to slide the bars v18 inwardly, which in vturn raise the bars 15 and retract the bolts 9, thereby unlocking the caps 4.

At the lower end of theshaft or rod 2O is*L mounted a plug-valve 26, serving as the watersupply valve and fitting into a port or opening 27 in the bottom of the hydrant. In order that the valve 26 may not be opened until after opportunity has been given for a hose to `be secured to the port or nozzle 2, a collar 28 is secured to the shaft 20, and is located (when the shaft is in its upper normal position) in the upper end of a chamber 29in t-he valve 26. As the shaft 2O is moved down in its rotation the collar 28 is carried down with it to the bottom of the chamber 29 in valve 26, the rod meanwhile acting on the eccentrics 19 to unlock the bolts 9. Upon the further rotation of the shaft 2O the collar 28 bears against the bottom of chamber 29. The valve 26 is thereby unseated and the water is admitted to the hydrant, a hose having been in the meantime attached to port 2. As the main valve 26 is opened, the waste-passage 30 is closed by au auxiliary valve 31, which is suspended by pivoted links 32 and 33 to an arm 34, pivoted to the interior wall of the hydrant and having its free end engaging a peripheral groove in a fixed collar 35 on the shaft 20, said collar being located at a suitable distance above the valve 26. As the shaft 2O descends the collar 35, engaging arm 34, moves it down and causes the valve 31 to close passage 30.

36 is an internally opening valve closing the inner orifice of the port or nozzle 3 to prevent the escape of water through the nozzle. The valve 36 isheld in its normal closed position by means of an arm 37, the inner end of which rests against the surface of a sleeve 38, fixed on the shaft or rod 20. As shown in Fig. 1, the arm 37 is rigidly connected with the valve 36, which is pivotally connected with the casing. The center of gravity of the Valve 36 and the arm 37 is back of the pivotal point of the arm 37, so that if the sleeve 38 were not present, as in Fig. 1, the valve would automatically open by gravity. As the shaft 20 descends, the sleeve 38 is carried below the end of arm 37 and the latter drops back into the annular space or recess between the sleeve 38 and a collar 39, thus opening the valve 36. As the shaft 2O descends still farther the collar 39, encounters the end of the arm 37 and presses the same down far enough to open the valve 36 to its full extent. theshaft 2O has thus been lowered to open the water-supply valve 26 to its full extent, the collar 39 is above and in contact with the arm 37, so that the valve 36 is prevented from being closed by the water pressure. The movement just described takes place after the water has been admitted to the hydrant and after opportunity has been given to attach a hose to the port or nozzle 3, but before the hydrant has been filled with water, and consequently before the water-pressure can prevent the valve 36 dropping open by gravity. It will be noted that the peripheral groove between the sleeve 38 and the collar, rib, or projection 39 constitutes in effect a recess in the shaft or rod, so that normally the arm 37 rests against a portion of the shaft or rod, drops into said recess when the shaft is lowered, and is swung down and held open by the upper margin of the recess acting upon the arm. It will readily be 'understood that a reverse movement of the shaft 2O will close the valves 36 and 26, open the valve 31, and cause the bolts 9 to lock the caps 4,'theyl1aving been lifted into their closed positions.

In operation the hose may be quickly attached to the hydrant, as upon turning the shaft 2O slightly with a key or wrench the caps 4 are unlocked and drop out of the way. A hose is then attached to port 2. A further turn of the rod opens the water-supply valve and admits the water. A hose may then be attached to port 3, and a further turn of rod 2O opens-valve 36, and water is discharged through port 3, or, if two firemen are at the hydrant one can turn the shaft 2O continu- IOO TIO

ously and the other will have time to attach hose in succession at both nozzles before the water flows therethrough.

While I have described the specific mechanism for unlocking the caps and operating the valves, I do not desire to confine myself thereto, as other suitable mechanism may be employed. AS an example of afeasible modification, Fig. 5 shows a different construction of the valve 36, which in somerespects is preferable to that shown in Fig. 1. In this modification the arm 37 is one arm of an elbow-lever which is pivoted to the casing. To the other arm 40 of the lever the valve 36 is pivoted at its center. This construction enables the valve to seat squarely and evenly against its seat.

l lay no broad claim in this application for the particular form of capshown and locking mechanism connected therewith, as that matter is embraced in another application filed by me August 8, 1890, Serial No. 361,416.
