LEOPOLD' DREIFUSS, OF DANVILLE, PENNSYLVANIA.
Hose-CO PLING.
SPECIFICATION forming part of Letters Pa ans. 761,950, 'dated June 7,1904.
Application filed septernberfi, 1902 Serial No. 172,152. -(ITo'niodeh) To all rah/0171 it concern I l Be it known that I, LnoroLD DREIFUSS, a
citizen of the United States, residing at Danville, in the county of Montour and State of Pennsylvania, have invented a new and useful Hose-Coupling, of specification.
My invention relates to hose-couplings of the type which are employed for connecting the hose with the fire hydrant or plug, and has for its-objeetsto produce a device of this which the following is a character of simple construction which will be efficient in operation and one in which the parts may be readily connected or, disconnected and will when coupled present a perfect union, by which leakage is entirely obviated.
novel details of construction and combination of parts more fully hereinafter described.
'In the accompanying drawings, Figure l is a verticallongitudinal section showing the parts coupled. Fig. 2 is a transverse sectional elevationon the line 2 2 of Fig. 1. Figs. 3 and 1 are detail perspective views. Fig. 5 is a detail sectional view.
Referring to the drawings, 1' indicates a fire hydrant or plug provided with a laterally-extending nozzle 2, having a central escapeopening 3, through which the water from the.
hydrant is discharged,the'wall of the nozzle being provided with a pair of diametrically oppositely disposed transverse perforations 4.
Disposed within and preferably formed integral with the nozzle 2 is a circular headblock or flange 5, having a' forwardly-projecting tubular extension 6, externally surrounded at its point of junction with the head 5 by an outwardly flaring or diverging peripheral socket 7 8 indicates a coupling sleeve or thimble provided with an externally-threaded portion which receives the rear end of the hose 9 and with an internally-threaded portion receiving the forward end of aeoupling member 10, provided at its rear end with a substantially eonical couplinghead 11. This head, which seats and fits within the socket 7, presents at its front an abrupt peripheral shoulder 12,
To these ends the invention comprises the faces of which are curved to conform to the curvature of the extension 6,'are designed for engagement with the shoulder 12 of the coupling-head 11 to maintain the parts in coupled engagement and are held normally in engaging position each by means of a pair of normally expanded springs 16. seated at one end upon studs 17 and at the other end in socketed lugs 18, carried, respectively, by the lockingmember and inner wall of the nozzle 2, upon which parts the springs hear at their ends. At this point it is to be noted" that the inner edge walls of the locking members are inwardly beveled, as at 19, in a plane corresponding to the bevel. of the outer face of the head 11, whereby the latter will operate the locking members automatically when the coupling member 10 is moved to coupling position.
The locking devices 13 are each provided with an actuating member throughwhich they may be manually operated for releasing the coupling-head 11. i These actuating members preferablycomprise each a hand piece 20, having a shank or extension 21, provided at its inner end with a screw-threaded stud 22, engaging a correspondingly-threaded socket .formed in the member 13, it being apparent that through these members, the shanks 21 of which extend through the openings 4, the locking devices may be retracted against the action of the springs 16 to release the coupling-head and, further, that these actuating devices may, when desired, be removed to prevent unauthorized operation of the locks.
For securing the locking devices in position upon the head 5 I employ a clamping-ring 23, which fits within the nozzle 2 upon the outer faces of the locking members and is secured to the head 5 through the medium of a pair of straps 24, which are oppositely disposed and have their inner ends angularly bent, as at 25, and secured by screws or otherwise to the outer face of the block, the outer ends of the straps being after the ring has been inserted in position bent downward upon the outer face of the latter, as indicated by dotted lines in Fig. 3, and secured by screws or the like.
Under normal conditions the outer end of the nozzle 2 is closed by a cap 26, secured in place preferably by a locking member 27, journaled for rotation in a socketed thimble 28, tapped into the cap adjacent to the wall of the nozzle, which latter has a socket 29, engaged by an angularly-bent finger or portion 30 of the locking member. Thelocking member is turned to and from engaging position by a suitable tool or wrench (not shown) formed to fit a square socket 31, provided at the outer end of the member 27. It Will of course be understood that the cap is provided with one or more of the locking members, as circumstances require, they being, however, similar in construction and operation with the one just described.
From the foregoing it will be seen that I produce a device of comparatively simple construction which is admirably adapted for the attainment of the ends in view; but it is to be understood, however, that I do not limit or confine myself to the precise details herein set forth, inasmuch as minor changes may be made therein Without departing from the spirit of the invention.
Having thus described my invention, what I claim is 1. The combination with a hydrant havinga discharge-nozzle, of a head-block situated in the nozzle and provided with a discharge-opening and a forwardly-opening socket wholly surrounding said discharge-opening, a hose having a coupling member provided with a surrounding head seated in said socket, and a plurality of locking devices associated with the nozzle for automatic engagement with the head.
2. The combination with a hydrant having a discharge-nozzle, of a head-block situated therein and provided with a tubular extension and a forwardly-opening socket surrounding the base of the latter, a hose having a coupling member seated upon the extension and provided with a head seated in the socket, and a plurality of locking devices carried by the nozzle for automatic engagement with the head.
3. The combination with ahydrant having a discharge-nozzle, of a head -block situated therein and provided with a diselnu'ge-opening and a forwardly-opening socket wholly surrounding the discharge-opening, a hose having a coupling member provided with a. surrounding head seated in the socket, a plurality of locking devices movably associatial with the nozzle, springs for automatically moving said devices into engagement with the head, and means for disengaging the devices.
4. The combination with a hydranthaving a nozzle provided with transverse apertures, of a head-block situated within the nozzle and provided with guideways, a plurality of locking devices having shanks engaging the apertures and studs working in the guideways, a hose having a coupling member designed for engagement by the devices, means for maintaining the devices in engaging position, and means for actuating the devices to release the member.
5. The combination with ahydrant having a nozzle provided with transvm'se apertures, 01' a head-block situated in the nozzle and provided with guideways, a plurality of locking devices having shanks engaging the apertures and studs working in the guideways, a hose having a coupling member designed for engagement by the devices, means for maintaining the devices in engaging position, and actuating members detachably engaged with the devices.
6. The combination with a hydrant having a nozzle provided with transverse apertures, of a head-block situated in the nozzle and provided with guideways, a plurality of locking devices having shanks engaging the apertures and studs working in the guideways, a clamping-ring overlying the devices and connected with the head-block, a hose having a coupling member designed for engagement by the devices, means for maintaining the devices in engaging position, and means for actuating the devices to release the member.
In testimony that 1 claim the foregoing as my own I have hereto aiiixed my signature in the presence of two witnesses.
