Patented Mar. 30, 1948 WATER SERVICE APPARATUS John T. McGarry, Cincinnati, Ohio; Mary Frances McGarry,'executrix of said John T. McGarry, deceased, assignor to Railroad Products Company, Cincinnati, Ohio, a corporation of Ohio Application April 4, 1944, Serial No. 529,485 6 Claims. (01. 137-43) My invention relates to hydrants and the like, and more especially to those of the type in which the outlet, spout, or hose connection is positioned nearly at ground level in a box or the like having a lid which is opened for access to the spout for connection of the hose, and is kept closed normally to exclude foreign substances from the spout or hose connection.

In those examples of hydrants of this type heretofore in use, so far as I am aware, the spout or part to which the hose is to be connected actually is below ground level and depends especially upon the effectiveness of the box lid when this is closed for exclusion of the substances which would pollute the spout. If its threads or other portions engaging for making the hose connection bear impurities, these are forced inside the hose to mingle with the water. Thus the water delivered by the hose, as for instance a hose delivering water to railroad trains, may be contaminated with matter that may cause widespread disease when used by the many people on the trains. Of course I am not limited to the use of my invention in railway service, though that is where it is especially important, for sanitation in the respects just noted.

An object of my invention is to dispose the hose connection means so that any impurities getting past the box lid will not contact this connection; and will be, if they are'accompanied by ground water, washed from the box to a drain of some type, so that the danger of entrance of 1301- ing description, illustrated in the accompanying drawings, in which Figure 1 is a sectional side elevation of an entire hydrant structure selected for illustration of th relation of my invention to the other parts of the hydrant, with the box lid closed;

Fig. 2 is a plan view of the upper part shown in Fig. 1, with the box lid open, but with the main valve operating parts in their positions incident to the main valve being closed as in Fig 1;

and

Fig. 3 is a vertical cross section of the same on the plane of the line 3-3 of Pig. 2.

The lower part of the hydrant structure as illustrated in Fig. 1 is substantially the same as that disclosed and claimed in my copending application, Serial N0. 524,392, filed February 29, 1944. It will be understood that I am not limited, however, to this particular lower structure which, though preferred is illustrational only; as my improved hose connecting upper structure is usable along with any one of various lower structures for the general purpose of the one her illustrated. This one is preferred because it provides for disposal of the residue of water left in the riser after closure of the hydrant, so that it will not freeze in the riser; and further, so finally disposing of the residue water that it does not again enter the riser, and that connection to a sewer is unnecessary and the risk of contamination of th riser by contamination back surging from the sewer is eliminated.

For clear understanding, this exemplary lower structure will be described in limited detail, preliminary to description of the example of my present invention associated and coordinated with this lower structure and imposing some of the details thereof as herein shown.

As herein shown, there is a unit comprisingthree vertically disposed chambers. The widest chamber l at the right contains control mechanism for emptying this chamber of water draining into it. The middle chamber 2 surrounds the riser I3. The chamber 3 at the left is to receive and dispose of the water taken from the right hand chamber. There is a'fourth chamber 4 below the mechanism chamber I and the riser chamber 2, into the right end of which enters the water supply main 5 controlled by a stop valve 6. Leading out of the bottom of the left hand chamber 3 is the perforated bulb 1 to dissipate the water from this chamber 3 into-the surrounding ground which may be rocks, not shown, in the familiar manner of drainage.

Leading up from the left end part of bottom chamber 4 is the stand pipe 8 carrying on its top the main valve casing 9 in which is the main valve In seating downwardly to close the passage ll through which water goes up from the standpipe when the valve Ill is lifted from its seat to flow up through passages l'2 in casing 9 into riser [3 leading up from the top of casing 9. In the left side of this casing 9 is a drain port 14 which is open when valve In is seated but is closed by the valve when the valve is lifted from its seat; That is, when water is stopped from flowing up through riser [3, th water remaining in the riser drains through port [4 into middle casing chamber 2 that surrounds the riser. At the bottom is a communication port I5 through which the drained water may pass into the right hand chamber I.

The right hand chamber I contains any suitable mechanism, not material to the present invention, adapted for operation when the level of drainage water from the riser reaches a predetermined level in chambers I and 2, to. cause ejec tion of the drainage water through a discharge pipe 23 to the waste chamber 3, which relieves through the bulb I.

To facilitate removal of all of this mechanism upward from chamber I, for servicing the-mech-z ceives the spout chamber 42 which has a bottom opening receiving the upper :end of riser I3. Across the opening forthe left hand or drainage chamber 3 is a perforated disk or strainer 43; The top end part of discharge pipe 23 joins the main lower vertical pipe by a union 44, just above which this part curves to a horiozntal direction and; it'also curves'around spout chamber 42 and then downward, opening over strainer 43a substantial distance up from it. This top end .partzof pipe 23'of course is detached when the plug disk 23 is to be removed. The opening in the top of the middle or riser chamber 2 is a large enough to permit passage of main valve'casing 9 along with riser I3 and spout chamber42, which detaches at this Opening while main valve 9 prefer-ably'de' taches from standpipe 8. Before removing these parts and the mechanism in chamber I; the stop valve 6 is closed, to confine the high pressure water in main 5; this being readily done, and valve 6 being closed after the parts are restored, by means of the elongated stem 45 extending up into a socket member 46 at'ground level, in which the square end of the stem may be engaged to turn the stem. J

At the left the spout chamber42 has the upwardly curving spout 41; and the chamber has a detachable top 48 containing astuffing box 49 through'which the main valve operatingrod 50 extends down centrally in riser I3 to connect with main valve II and up above top 4.8 to pivotally connect with a lever bar 5I fulcrumed at the left on a link 52' pivoted to the left edge of top 48 and at the right guided between two guides 53, parts of top 48. The handle 54 is pivoted to lever bar H at the right of these guides,'and has a toeglearm 55 extending down from its pivot-receiving end to pivot to a lower toggle link 56 the bottom en'd-of whioh pivots to an arm 51 extending from'the side of and being part of Spout chamber 42; Within this chamber ahelical spring 58 surrounds operating rod 50 and is compressed between the gland of stuffing box 49 and a collar 59 on rod59 which is part of the upper end section 59' of rod 50, into which the 'main lower section is screwed. This sprin holds main valve I5 down to its seat against the high pressure water unless overcome by action of the operator by means of handle 54 and associated parts just described; The lever or handle 54 and the toggle link 56 are so proportioned and disposed that raising handle54 straightens the toggle with V powerful action on the main valve against the seating spring 58 just above described. Stop lugs 60 and 6| on the link 55 and arm 5'! permit the toggle to pass slightly to ,left of straight vertical position, holding main valve In open until handle 54 is forcibly depressed, releasing spring 58.

"The top partof the unit, above the partition .40, constitutes the equivalent of the usual box, so called, of prior apparatus of this general type.

'It extends' appreciably above the ground line G which may be the top surface of a concrete railroad station platform, for instance; and it preferabiy has embedded in the surface material the outward flange 62 with its top surface exposed. The lid 63 is of inverted trough shape, or of dome shape, with a rim 64 that fits all around the part or rim -65 of the unit above flange 62 and down on this flange, affordinga fair exclusion of matter from the box. But the fit of lid 6.3 is not relied upon for protecting the portions of hose connection from pollution.

"Were it spout .47 that received the hose detachably, when the hose is removed and the box closed by the lid, suchmatter, especially liquid,

7 getting from the ground past the lid, easily could .be in part deposited on the surfaces of the spout on which the hos'e connection surfaces will bear upon connection. Such pollution by this would be forced into the hose interior to be taken up by the water being delivered for potable use. This liability is because spout 41 is below the upper edge of'rim' 65. To elevate this spout would involve increase of the height of lid 63; though it isdesira-ble to minimize the height of the lid to avoid undue obstruction at ground line G- My invention comprises, therefore; a perman'ent con nection 65 of an intermediate hose 51 which leads up into-the dome part 6-8" of lid 63' to be permanently connectedto one ,matin'g'part 69.0f a hose connector attached to the underside of the lid.

As here shown, the connector, of whichthe other mating part "III isflseen iniFigs. 2 .and V3,. is, ofa quickly operatingkind, similar to couplings for: air and other ,hoseon trains. It willbe under stood that a screw. coupling or any other suitable coupling vmayjbeused; it being the nature of my invention that one mating part iscmounted up in lid" 6 abovethe .box' rim .65 or placeof en trance of pollution. Thedetachableusual hose II isseenconhectedto part B Q by its part it, andto beof any length to reach the place ofdelivery of the potable water, inthe usual manner.

The :lid 63 has hinges- 12 holding it to the box at therear, and has a finger notch 73 on its-front. edge for engaging it toopen it. Preferably the lid rim 641is slanted 'at -14-all around its four edges, to minimizestumblin'g on the lid; and the" 7 sides and ends of domepart 68 also are slanted for easy passagethereovezi- Though not so shown it will be understood 'thatthelid top surface may.

be roughened in familiar manner, to minimize slipping of persons thereon. A

Preferably lid 53. does not pass the vertical in 7 ward and lower openp'osition; since the lid will.

fall closed with its heavy rim fi4'forward" of vertical. Ea h hin e 12 has .a stop lug I5ito engage.

the top of a recess 75 in the box rim 55 as indie cated inl ig. 3; so that lid .63 cannot go farther backward. In Fig; 3,'theop'en lidzisrepresentedi aasasrrs by solid lines, and the closed lid is represented by broken lines.

Provision is shown for putting the closure of lid 63 under control of the operating handle or lever 54, according to the valve opening or valve closing position of the latter. The pivot pin ll fixed in the lower toggle link 5'6 and turning in arm 55 is extended backward to turn in a bearing 78 in the back wall of the box, adjacent to which it has fixed on it the segment E9. Fixed in lid 63 and projecting forward in such position as to engage the segment 79 when it is raised incident to raising handle 54 to open the main valve it], is a pin 80, for holding the lid 63 in its raised forwardly inclined open position in which it is shown. Depressing the handle 56 swings segment 79 down away from lid pin '80 so that the lid is free to close. The mode of operation is to raise the lid, holding it raised with one hand While connecting hose H and then raising handle 53 with the other, to open valve ill, upon which the segment and pin engagement is attained, to hold the lid open without the operators attention. He must close main valve 19 before disconnecting hose H; and to do so must depress handle as, releasing the lid to fall closed if he forgets to control it by hand.

The lid is not so heavy that the operator could not get control of it if he forgets as just supposed; so that there is no serious element of danger involved. However, such slight element as is present, as liability to strike a hand not on the lid is an aid toward insuring that the operator will keep a hand on the lid while detaching hose H and operatin the handle 54 to close main valve Hi. If his hand is on the lid when it is freed to close by these acts, it is unlikely that he will forget to close the lid in the usual and proper way. This precaution against neglect to close the lid is important in connection with my provision for protecting the hose connection by the lid; since if the lid were left open, that precaution would be nullified.

By having the riser l3 protected by the management of the residue drainage water as herein first described, and having the detachable hose connection protected as just described, I have provided a hydrant of the depressed type which is sanitary in its entirety; as is logical, since any neglected precaution is substantially certain to nullify the benefits of all other precautions.

Though my invention is herein rather precisely disclosed, it will be understood that modifications in construction and operation may occur in practice, and that I am limited only within the scope of the following claims.

I claim:
