HYDRANT.

Specification of Letters I'atent.

Patented Feb. 22, 1916.

Application fiIed March 12, 1915. Serial No. 13,981.

To all whom it may concern Be it known that I, GEORGE N. FRAZER, a citizen of the United States, and a resident of Eugene, in the county of Lane and State of Oregon, have invented a new and useful Improvement in Hydrants, of which the following is a specification.

This invention relates to an improvement in hydrants, and more particularly to that type disclosed in my patent application, Serial No. 874,193, allowed January 27, 1915.

One of the principal objects of the invention is to provide an improvement in the drainage means of the hydrant, such improvement embodying a drainage plug normally closing a drain opening, the plug be ing provided with a drain valve automatically operable when the inlet valve is in closed position, to be opened for providing a continuous drainage from the hydrant casing.

A further object is toprovide an improvement embodying the plug having a drain opening or channel arrangedtherein and controlled by a drain valve, means being provided whereby the inlet valve lever will automatically operate in raising or opening the drain valve when the inlet valve is in closed or seated position.

A further object is to provide a device of the class described which will be extremely simple, durable, eflicient in operation and inexpensive to manufacture.

With these and other objects in view which will become apparent as the description proceeds, the invention resides in the construction, combination and arrangement of parts hereinafter more fully described and claimed and illustrated in the accompanying drawing in which like characters of reference indicate like parts throughout the several figures, of which Figure 1 represents a view in section taken through the base or inlet section of the hydrant, showing the improvement in place therein, Fig. 2represents a top plan view of the drainage plug removed, and Fig. 3 represents a view in section taken vertically on the plane indicated by the line 3-3 of Fig. 2, looking in the direction indicated by the arrows.

In carrying out my invention, I provide a base or inlet section 5, having a lateral inlet .or port 6. The base or inlet section is substantially similar to that described and shown in my application, Serial No. 874,193, above mentioned.

Extending within the inlet or port 6, is a bushing 7 provided with an annular outwardly extending flange 8, adapted to rest and be secured against the outer face of the hydrant adjacent the port. The inner end of the bushing extends slightly within the base section 5 and is adapted to act as a seat for the inlet valve 9. In lieu of the bushing, to which the water main leads, I may use an elbow or section of the type disclosed in my prior application.

The inlet valve 9 is connected by means of a link or links 10, with the rod 11 actuable by mechanism described in my prior application in such manner as to swing the valve against and away from its seat in closing or opening the inlet port. The valve is suitably faced with leather or rubber indicated at 12, adapted to be compressed against the valve seat when said valve is closed in order to provide a leak proof joint. Valve 9 is formed on the upper end of a valve lever 13, which corresponds to the analogous lever illustrated in my prior application.

In connection with the improvement forming the subject of my present application, the lower end of the base or inlet section is preferably, but not necessarily, offset as at 141. This offset portion at its lower end is provided with an opening as at 15. A bushing 16 having a funnel or cone-shaped bore 17 is disposed within opening 15, and is provided with an external annular flange 18, which rests against the bottom of the base or inlet section and may be in any suitable manner secured thereto. The extreme lower end of bore 17 merges with the cylindrical bore 19 in the lower portion of the bushing. This bushing is adapted to accommodate a drain plug 20. The plug is provided on its upper face with a pair of spaced ears 21 between which the lower end of lever 13 is pivoted as at 22. The main portion of the plug is substantially cylindrical and at its lower end is externally threaded as at 23. The upper end of the plug is provided with an outwardly extending annular flange 24:, having a beveled surface 25. The flange serves as an anchorage or hearing for one end of a series of rubber or other suitable washers 26, which are slipped upon the body portion of the plug beneath said flange. The washers similar to the flange, have their outer edges beveled as at 27 at an inclination adapted to conform to the inclination of the walls of bore 17. In order that the washers may be securely maintained in place, I thread upon the lower end of the plug a closed nut 28. When in position the nut compresses the washers against flange 24 and prevents their accidental removal. The lower or closed end of the nut occurs in spaced relation to the lower edge or face of the plug when the nut is turned home, a chamber 29 being formed. This chamber is provided with outlet openings 30, communicating with the outside atmosphere. A bore or outlet passage 31 provides communication between chamber 29 and the interior of the base or inlet section of the hydrant. In order that closed nut 28 will not become accidentally removed or lost, I provide a bolt 32, extending through the closed end of the nut and turned into a threaded recess 33 provided in the body of the drain plug. The outlet passage or bore 31 is controlled by a drain valve 34. having a fluted or ribbed stem 35, projecting with the bore or passage. A compressible washer or facing 36 provided on the valve is adapted to be compressed against the upper face of the plug adjacent the bore or outlet passage when the drain valve is in closed position.

The drain valve is operated from the lever 13 through the medium of a lever 37. This lever is disposed between the lower end of lever 13 and the drain plug, and is centrally pivoted at 38 between a pair of ears 39 rising from the plug and between the ears 21. What may be termed the inner end of lever 37 is provided with a slot or elongated opening 40 through which projects a pin 41, carried by a pair of cars 42, which arise from the upper surface of drain valve 34. The outer end of the drain valve lever 37 is provided with an adjustable pin or bolt 43, which extends upwardly toward the lever 15. The latter adjacent its lower end has a laterally extending lug or dog 44 provided thereon, said dog having a fiat under'surface 45.

When the inlet valve 9 is in closed position. the valve lever 13 is swung from a vertical to an inclined position. As it nears the limit of its inclination, the lug 44 engages with the pin or bolt 43, thus depressing the outer end and hence raising the inner end of the drain valve lever 37. This operation serves to lift the drain valve from its seat in order to establish communication through the bore 31, chamber 29 and outlet 30. so that any water which may remain within the hydrant casing will find free passage to the exterior of said casing.

In opening the inlet valve by reason of the rod 11 being raised vertically, the valve lever 13 is moved from an inclined to a vertical positionand in so doing the lug 44 leaves the pin or bolt 43, and the drain valve 34 is thus allowed by its own weight to close. Furthermore when the water from the water main rushes into the base or inlet section, its pressure maintains the drain valve in closed position and similarly acts upon the upper surface of plug 20 in order to maintain the latter in tightly seated position so that there will be no leakage at either of these points during the time that the hydrant casing is flooded.

The whole apparatus, that is, the inlet valve, link 10, rod 11, valve lever 13, and the plug 20, together with the mechanism carried thereby is adapted to be lifted clean out of the base or inlet section, when an inspection of the hydrant is desired, as in the manner set out in my previous application. 'l/Vhen this is done the bottom of the hydrant casing is opened, and the interior of i t the casing may therefore be readily inspected and cleaned. In placing the device within the hydrant it is lowered therein, and the plug is properly guided into engagement with the bushing 16, initially by the act of the closed nut 28, which is provided with an annular beveled surface 46 at its lower end, in engaging and centering within the bore of the bushing.

In order that the inlet valve may also readily be guided into its proper position. the base or inlet section 5 is provided adjacent the inlet port 6, and near the lower point of the latter with a pair of inwardly extending al-ined lugs 47. These lugs extend inwardly fromthe opposite sides of. the base section, and are spaced apart a distance substantially equal to or slightly greater than the width of thevalve lever 13 on each side of which they lie. When the mechanism is lowered within the hydrant, the lever is engaged between the lugs 47 so as to guide the inlet valve properly into position against its seat. The distanceof lugs 47 from the rear wall of the base or inlet section is great enough to allow free passageof the drain plug between said lugs and rear wall during the operation of raising and lowering the apparatus within the base.

Although I have described the preferred embodiment of my invention I may desire to I make such changes in the construction, combination and arrangement of parts thereof as do not depart from the spirit of the inven tion, and the scope of the appended claims.
