SELF-CLOSING- YARD-HYDRANT.

Specification of Letters Patent.

Patented Mar. 28, 1916.

Application filed November 20, 1913. Sera1No. 802,120.

To all whom t may concern.'

Be it known that 1, HORACE F. NEUMEYER, a citizen of the United States, residing at Macungie, in the county of Lehigh and State of Pennsylvania, have invented a new and useful Self-Closing Yard-Hydrant, of which the following is a specification.

One object of the present invention is to provide a hydrant which will not waste water when Working under a low pressure.

Another object of the invention is to provide a hydrant of the type hereinafter described having novel means' whereby, at nol time, a continuous passage exists through the supply pipe, through the bypass and through the drainage opening ofthe hydrant.

It is within theV scope of the invention to improve generally and to enhance the utility of, devices of that typevto which the present invention appertains.

With the above vand other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawingz-Figure 1 shows in vertical longitudinal section, the upper portion of a hydrant constructed in accordance with the present invention; Fig. 2 shows in vertical longitudinal section, the lower portion of the hydrant herein disclosed, the parts appearing in the positions which they will' assume while the water is flowing from the source of supply through the hydrant; Fig. 3 is a vertical longitudinal section of the loweryportion of the hydrant, the View depicting the parts as the same will appear at an intermediate stage and when both the bypass and the source of 'water supply are closed: Fig. 4 is a vertical longitudinal section of the lower portion of the hydrant, showing the parts as they will appear after the source of'water supply has been cut od and after the `bypass has been opened to permit a drainage of the hydrant; Fig. 5 is a cross section on the line 5-5 of Fig. 3: Fig. 6 is a cross section on the line 6--6 of Fig. 1.

In carrying out the invention there is provided a casing which is a composite structure, the casing comprising a jacket 1 to the upper end of which is secured a cap V2 having ears 3 receiving a pivot element 4 upon which is fulcrumed a lever 5 carrying at its outer end arpivot element 6 supporting a Vplunger-7 and supporting also a pawl 8 adapted under circumstances'to be pointed out hereinafter to engage with the upper face 9 of the cap 2 but, at the will of the operator, adapted to be moved out of engagement therewith. Y

The plunger 7 works in an opening 10 formed inthe cap 2 and below the opening 10 the cap is provided with a recess 11. By means of a pivot element 12, the lower end of the plunger 7 is connected with a plug 14, constitutinga part of a conduit, the remaining elements of which will be described hereinafter. rlhe plug 14 is threaded or otherwise secured in a coupling 15. Surrounding the plunger 7 is -a compression spring 16,

abutting at Vits lower end against the coupling 15, the upper end of the spring 16 being housed in the recess 11, land having an abutment against the cap 2. Mounted in one side of the coupling 15 is a nozzle 17, extended outwardly through a slot 18 formed in the jacket 1. Secured in place upon the nozzle 17 by means of a nut 19 or otherwise is a closure plate 2O for the slot 1S, the closure plate 20 being mounted to reciprocate upon a flat table 21 formed on the outer face of the jacket 1 around the slot 18 therein.

The conduit above mentioned further includes a pipe 22, the upper end of which is threaded intothe coupling 15. VThe lower end 0f the jacket 1 is threaded into a coupling 23 formed inone side with a lug containing a drainage outlet 24. Threaded into the lower end of the coupling 23 and constituting a part of the casing is acoupling 25 which may be united with a pipe 26 whereby water is delivered into the casing and into the conduit.

A sleeve 27 is threaded onto the lower end of the pipe 22 and into the sleeve 2T is threaded a bushing 2S provided with an outwardly projecting flange 29. A primary valve, preferably taking the form of a cup leather and denoted by. the'numeral 30 is bound between the flange 29 and the lower end of the sleeve 27. This valve 30 conforms closely to the bore of the coupling 25. In the side wallv of thecouplingr 25 adjacent the valve 30 is formed an upright bypass groove 31. The bushing 2S includes a transverse bridge 32 connected with the body portion of the bushing by upright arms 33. Upon thelower face of the bridge 32 there is a lug 34. Y

A secondary valve is slidably mounted in the bridge 32, and this secondary valve includes a stem 35.which is immediately received in the bridge. The secondary valve further includes a head 36 located below the bridge, the head being provided with a circumscribing flange 37 which extends above and below the head proper. The upwardly projecting poi-tienl of the flange 37 retains a spring 38, the upper end of which surroundsV the lug 34 on the bridge 32. This spring 38 preferably is fashioned from a flat strip; of metal formed into the shape of a\cone,the longer transverse dimension of the strip being vertically disposed. By meansof a screw 39 or the like which'is threaded into the head 36, a resilient `washer' 40 is held against the bridge and withinthe contour of the depending portion of the lange 37. This washer 40 is adapted to coperate with the seat 41 connected by means of a flange42 with the coupling `25.

Vxhen the water supply to the hydrant is to lbe cut oif,the spring 16 forces the pipe 22 downwardly and the parts appear as shown in Fig. 4. Under such circumstances, the primary valve or cup leather A lies between-the ends of the bypass 31 and the bypass is opened.A The spring 38 is put under compression and the washer 40 is held against the valve` seat 41. When the parts Vare arranged as above described water cannot ypass upwardly through the pipe 26 and through the valveseat 41, be-

cause the' latter is closed by the valve 35-V 36-40. Any water which may have accumula-ted in the pipe portion 22 of the conduit, however, will flow downwardly through i the bushing 28, around the edge of `the cup leather, upwardly through the bypass 31, between the sleeve 27 and the wall of the coupling 25 and thence pass out.` of the coupling 23 by way of the drainage outlet 24. Now when yit is desiredV to. open4 the supply pipey 26 and to permit the water to flow out through the pipe 22 and the nozzle 17,. `the free outerl end of the lever 5 is depressed, the plunger 7 elevating the pipe 22. Under such circumstances, the parts will first appear as shown` in Fig.,3.` Vhen the pipe 22 moves upwardly, the primary valve or cup leather 30 will move upwardly, into the position shown in Fig. 3 and `will cut oli the upper end of the bypass 31.l During this limited Vupward movement of the pipe 22, the spring 38 will maintain the secondary valve 35-36-40 in engagement withthe seat 41, as shown in Fig. 3. Therefore, during the opening movement olf the l hydrant, wa ter cannot flow directly from the -pipe26 through the seat 41, through the bypass 31 and out of the outlet 24, it beingy observed that the. secondaryvalve remains. onV the seat 41 untill lthe primary valve.` 30' has closed the bypass 31. Continued movement of the free end'ofthe lever 5 will cause the parts to be-positioned las .shownf in Fig. 2.` As there disclosed,- the primary, valve 30 still cuts oli' the bypass 31, but ther. pipe 22 has been lifted sufiiciently so that the washer 40 'of the'secondary valve no longer rests on the seat 41. Thereupon. water. is free to How through the pipe 26 and outl of the nozzle 17. c Considering the description of Fig. 3com-` versely, from the foregoing description: 80 thereof it will be obvious that upona closing movement, the washer `40iof 'the secondary valve will'engage with the-seat 41 before` the primary valve 30- moves into an 'opening4 position with respect to the bypass31.

Recalling the function `'of the springl` -it will be 4obvious that waterwill flow. through the pipe 22 and throughthe nozzle: 17 only so long as the free. end of thelever: 17 is depressed. Should it. be desiredl to se. cure a continuous flow through the piper22. and the nozzle 17 ,l the pawl 8 'isk swung back-1 y wardly into the position lshown in Fig. 1, the lower end of they pawl engaging with' the upper end face 9 of the cap 2. Iny this mannenthe plungerf andthe pipe 22will be held elevated, against `the action oflthe spring 16 and the valves` at thelower endo-z the hydrant willY appear asshown in Fig. 2.

Havingl thus described the: invention, 10g what is claimed is 1. Ina .hydrant of the classL describedy` a f casing having a drainageoutlerz'` a valve seat i and a by-pass. located between the outlet 1 and the seat; a conduit mounted to slide in 105,

the casing -in the direction of its length;.a y. primary valve carriedby `the conduity and 3 movableitherewith to lopen the by-pass; ai secondary valve movably supported on thev conduit and cooperating with lthe seat; 4an i110v auxiliary spring bearing j against: they conduit and the secondaryI valve to imaintainf the secondaryvalve engaged with the seat-f: while the primary valve is moving to open the byepass, and toI maintain the secondary 115 .i

serving to overcomethe -eort of the auml-'V1204 iary springl and serving .to overcome` the irictionbetween the primarylvalve and :the1 casing.V
