SPECIFICATION forming` part of Letters PatentNo. 746,125, dated. December '8,v 1903.

' Application nea January 16. 190s. sein No. 139.263. (No modem Y To all whom t may concern: i A

Beit known that I, THOMAS FRANCIS MUR-l PHY, a citizen of the United States, and' a resident of vNew York, county ofv New York, and State of New York, have invented certain new and useful Improvements in Automatic Hydrants,of which the followingis aspecification, reference being had to the accompanying drawings, forming a part thereof, in which similar characters of reference indicate correspending parts.

This invention relates to automatic hydrants, and has for its object to provide an efficient and improved apparatus of this character which isf` especiallyadapted for use in vpublic placesas parks, the construction being such as to prevent waste of water and readily supply any demand in required quantities.

The apparatus embodies principally a suitably-housed Valve which is normally seated over the source of watersupply `and a drinking vessel arranged in connection `with n the valve and of such relative proportion In ythe accompanying drawings, I forming part of this specication, Figure 1 is a vertical sectional elevation o f my improvedhydrant; Fig. 2, a sectional plan view taken on the line :n of Fig. l, and Fig. 3 'is a vertical sectional elevation illustratinga modification of construction. v

In .the drawings as illustrated by Figs. 1 andv 2, A represents a metallic housing of T'- shaped contour embodying the vertical cylindrical part 1 andv laterally-extended part 2. Threaded into the upper end of the cylinder 1 is a plug B, and the lower end of said cylinder is threadedto a supply-pipe C, which communicates with the source of water-supply. A tubular spout D is threaded inr-o the lateral extension 2 for the discharge of water.

Seated on the upper end of the supply-pipe y ,i C' is a valve E, which embodies the metallic Patented December s, 19oa.

Adisk e and rubber or other flexible disk c', the

latter being held on the disk c by means of the screw e2, whereby it., may be renewed when worn.

lcentral opening leading through the plug B to allow vertical-movementof'the stem with-V Extended from the disk e isa stem E', which is ground to dt within a verticalZ 4which forms, preferably, an integrall part of the housing A. The outer end of the lever F is provided with an eye f, which engages one end of a chain-Gr.l This said chain is inI connection with a drinking vessel H, which embodies the bowl or cup h, handle h', and eye h2, which is secured to the lower end of 'the chain G.

' The above-described drinking vessel H is `composed, preferably, of metal, and it is Of v suiiicientweight to overcome by its gravity the pressure from the water-main and keep the valve E seated over the outlet of the supply-pipe C when said vessel is in suspended position, as illustrated by full lines, Fig. 1 of toPOstion illustrated by dotted lines, Fig. 1, the'pressure from the main forces the valve E upwardly, causing the washer c4 to rest against the lower end of the plug B to prevent 4leakage and at the same time allowing free outflow of water through the spout D.

Incasing the above-described construction is a hollow standard I, embodying ataper ing upright 7l, the drip-basin t', circular dogtrough 012, and base is, suitable anchor-posts '4 being provided 'to keep the structure in rigid upright position. The top of the standard I is maintained normally closed by means of the cap I', having the slot i6 to accommopurpose of repairing the hydrant.

An outlet-opening 115 is extended from the basin t into the upright il to allow waste water to drip into the dog-trough i2. To prevent overflow of the dog-trough, a discharge or waste pipe .I is extended through the bottom of the dog-trough to a point slightly below the upper level thereof. The supply-pipe C communicates with an auxiliary pipe C', which leads from the main to provide a continuous supply of water to the device.

As a means of access to the inner part of the trough 2, whereby the same may be cleaned, a doorway I2 is formed through the standard I and provided with a normally closed door I3.

To assure instant opening ofthe valve E when the vessel H is lifted, a spring, as f', is located beneath the lever F to lift said lever and allow free upward movement of said valve and its stem; but the nature of this spring is such that its tension is readily overcome by the gravity of the vessel H.

In the modification of my invention illustrated by Fig. 3 of the drawings the hydrant is housed within a bowl K, having an overhanging hood K', and the spoilt embodies the tubular sections 5, 6, and 7, held together by suitable elbows 8. This housing is adapted to be set within a recess of a wall of a building, car, &c., whereby the bowl only extends outwardly. In this structure the lever F is provided with an upwardly-extended part f3, which bears against the under part of a hinged screen or drip-plate L, whereby said lever by the action of its spring f4 will lift the dripplate to allow the valve E to open by pressure from the main when no Weight is on the drip-plate L. The weight in this construction, as in the other previously described, embodies a cup or drinking vessel, as H', which normally rests upon the drip-plate L L to keep the Ivalve closed; but when said vessel is lifted the valve automatically opens to allow discharge of water through the spout 7.

In the application of the invention to insure perfect working thereof care is taken to so construct the outer parts that no projections or ledges are presented to support the vessel, which acts as a weight to keep the valve closed, whereby it must of necessity be suspended by its chain when notin use. Thus in the construction first described the cap I is rounded, so that the vessel H could not be placed thereon, and in the latter-described construction there is no place to normally support the vessel other than the drip-plate which rests upon the lever F.

In the operation and use of the device it is obvious that the simple act of lifting the drinking vessel causes the valve to open, whereby the water will run until the vessel is again allowed to exert its Weight against the pressure from the main. Thus I provide an automatic hydrant calculated to prevent wilfnl or careless waste of water, while at the same time an eflicient means for supply is provided.

I do not confine myself to the specific details of mechanical construction as herein shown and described, as it is obvious that under the scope of my invention I am entitled to slight structural variations.

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

l. In a drinking-fountain, the combination, with a supply-pipe leading from the main, a housing at the upper end thereof, having a discharge-spout, a valve having a verticalstem and a plug engaging around said stem, of a pivoted lever extended across and resting on the valve-stem, and a weight embodying a drinking vessel, and means whereby said weight is maintained in such normal relative arrangement with the said lever as to keep the valve closed over the outlet end of the supply-pipe, and a casing for the parts, substantially as shown and described.

2. In a hydrant, the combination, with a supply-pipe leading from the main, a housing at the upper end thereof supplied with a vertical removable plug and a laterally-extended discharge-nozzle, a double Valve having a vertical-stem extended through said plug and two iiexible surfaces to be seated respectively against the discharge end of the supply-pipe and the inner end of the plug, of a pivoted lever extended across and resting on the valve-stem, and a weight embodying a drinking vessel so connected with the lever that its gravity normally presses the lever against the valve-stein to maintain the Valve in closed condition, and a spring to lift the lever when the Weightis lifted bya consumer, and a casing inclosing the parts, substantially as shown and described.

3. In a hydrant, the combination with a supply-pipe leading from the main, a housing at the upper end thereof supplied with a vertical removable plug, and a laterally-extended discharge-nozzle, a double valve having a vertical stem extended through said plug and having two flexible surfaces to he seated alternately against the discharge end of the supply-pipe and the inner end of the said plug, of a pivoted lever ext-ended across and resting on the valve-stem, and a weight embodying a drinking vessel, and a chain connecting the free end of the pivoter] lever to said vessel, the weight of the drinking vessel being such that, when suspended, ils gravity maintains the valve in closed condition, and a hollow standard iuclosing the supply-pipe and housing, said standard having a removable cap with a slot therein through which the end of the said lever extends, substanlially as shown and described.

In testimony that I claim the foregoing as my invention l have signed my name, in presence of two witnesses, this 12th day of Jannary, i903.

THOMAS FRANCIS MURPHY.
