RELIEF-VALVE.
Specification of Letters Patent. I Patgnted S t 19" i916 Application filed March29, 1915. Serial No. 87,562;
To all whom it may concern:
Be it known that we, CHARLES JAMES RICHARDSON, of 19% Vauxhall Bridge road, Vestminster, London, S. 7., England, and
5 FRANK KNIGHT, of a9 Fairmont road, BriX- ton Hill, London, S. 7., England, have in'- vented certain new and useful Improvements in Relief-Valves; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to relief-valves and is designed for application to the water chambers of portable water filters intended for military and field purposes, although its use is not limited to such purpose.
In the type of filter referred to above a water chamber is provided having an inter- 0 nal cloth covered cage, through which the water is forced by means of a pump attached to the device. Owing to the fact that the cloths in many cases are impregnated with a filtering medium which becomes a permeable and flocculent covering, the subsequent charges of water do not succeed in penetrating the cloth, and continued pumping has in some cases forced in the sides of the cage and caused the cylinder to burst, thereby 0 rendering the filter useless.
The object of the present invention is to prevent such damage occurring, and also to enable the operator to allow the excess of the first charge of water to pass away unfiltered 5 for re-use, and with this end in view the invention consists in a relief valve, capable of external manual operation to allow the eX- cess of the first charge of water to pass away unfiltered and which is thereafter capable of 0 working automatically to relieve the pressure in the water chamber. Subsidiary features of the invention will be hereinafter described and claimed.
Reference will now be made to the accom- 5 panying drawings in which Figure 1 is an elevation partly in section showing the valve in the closed position. Fig. 2 is a view similar to Fig. 1, but with the valve in the open position, and Fig. 3 is 0 an external elevation of the relief valve.
In the drawings 6! represents a hollow cylindrical valve chamber the sides of which are perforated as shown at b, and which is provided with a flange 0 at its base for at- 5 tachment to the water vessel. Centrally disposed within the chambera is a valve rod (Z carrying at its lower end a valve 6 and a washer f of rubber or likematerial which when the valve is closed is seated at g.
The upper part of the valve chamber w is closed by means of a cap it through which the valve rod (Z protrudes, this rod carrying at its upper end a cross piece 2' protruding beyond the dimensions of the valve body, and an operating handle j. The cap it comprises a lower screw threaded portion adapted to engage an internal thread upon the chamber 0;, and an upper portion consisting of a flanged ring provided with deep slot is and shallower slots Z at right angles thereto, the contour of the upper edge of the r ng being such that passage of the cross plece z from one set of slots to the other is facil tated. When the valve is in the closed position the cross piece 71 is accommodated 1n the slots is but when the handle is given a quarter turn the cross piece lies within the slots Z and thereby maintains the valve in raised position.
A spring m is disposed between the underside of the valve cover it and a metal disk n adjacent to the washer f which spring is of the required strength to give relief according to requirements.
A screw 0 passes through the wall of the valve chamber a and the cap it to lock these members against relative rotation when the handle 7' is turned.
The operation of the device is as follows :VVhen water is first admitted to the filter chamber by means of a pump, the relief valve is lifted by the handle j which is turned to allow the cross piece to drop into the slots Z in the fianging on the cover It, so that the valve is raised and the first water from the filter allowed to flow away through slots 6 in the valve 6 and perforations b in the valve chamber a. Thereafter the valve is lifted by means of the handle j to disengage the cross piece 2' from the slots Z and turned, so that under the influence of the spring m the valve is restored to its seating, the cross piece i resting in the slots k. The device is now in condition for automatic operation, for, if the internal pressure exceeds the reaction of the spring m, the valve will lift against the action of the latter, and allow the fluid to pass through the slots 6 and emerge through the perforations b.
The tension of the spring m may be made adjustable upon the valve stem (13 and the valve cover h may also be formed with hexagonal sides for removal and adjustment.
A relief valve comprising in combination, a casing having outlet ports therein, a valve seat in said casing, a valve therefor provided with a spindle, a ring carried at the outer end of said spindle in the same plane therewith and affording a hand grip, a cross piece connected with saidspindle at right angles thereto and in a plane at right angles to the plane of said ring, and a rim on said casing having two pairs of slots of different depth cut therein, said cross piece resting alter nately in one pair of slots or the other according as the valveis closed or opened, one pair of slots lying at right angles to the other.
In testimony whereof we affix our signatures in presence of two Witnesses.
