characters of reference marked thereon,

which form a part of this application.

This invention relates to improvements in irrigation valves, theprincipal object of the invention being to produce a valve for the purpose which will be effectually watertight when closed.

A further object is to produce a valve which may be readily removed from its seat and lifted out for inspection or replacement of parts without the necessity of demounting the remainder of the irrigating-pipe unit to do so. In the present form of valve, the clamping bar is usually integral with the ring or valve seat member. This construction either prevents a good seating of the valve in case the parts are not accurately centered with each other, or else it necessitates a somewhat complicated means for providing the necessary latitude of movement to obtain a good seat. With my improved form of construction, the clamping bar is removable at will, and the disadvantages of poor seating, etc., have been overcome in a simple and eflicient manner as will be seen hereafter.

Another object has been to provide the valve with a removable turning handle, by means of which the valve may be turned either way on its seat or removed entirely from the valve casing.

A still further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly effective for the purposes for which it is designed.

These objects, I accomplish by means of such structure and relative arrangement of the parts as will fully appear by a perusal of the following specification and claims.

On the drawings, similar characters of reference indicate corresponding parts in the several views.

Figure 1 is a cross sectional elevation of my improved valve.

Fig. 2 is a fragmentary view taken on a line 2-2 of Fig. 1, showing a clampingbar retainer.

Fig. 3 is a perspective view, partly broken away, of a valve-key retainer, or box.

Fig. a is a perspective view of a valve-key or turner.

Referring now more particularly to the figures of reference on the drawings, the numeral 1 represents a metallic valve casing comprising an annular ring 1 having an outwardly projecting flange 2 thereon, which has a downwardly projecting flange 3 around the outer periphery thereof substantially parallel to the flange 1*.

Projecting upwardly from the flange 1 above the flange 2 is a lip 1 which forms a seat for the valve hereinafter described.

The flanges 1 and 3 taper slightly toward each other at their lower ends as at 4, the space therebetween holding the end of the concrete pipe 5 which is poured into and assembled with the member 1 in the pipe yard.

This casing, on account of its shape is well adapted to be used in this'operation. In making the pipe by the usual method, a rim is used at the bottom of the pipe to hold the ell. In setting the easing into the concrete, this ring is not used, the valve casing being substituted therefor. The pipe is then tamped on to the casing in the usual manner and with the same tools. The outer and inner rims of the casing being of the same diameter as the pipe, it fits easily into the mold.

The clamping bar 6 is formed separate from the member 1, having its ends adapted to project loosely into slots 7 provided in flat bosses 8 depending downwardly from the ring 1 These slots are of sufficient height to permit of'the thickness of the bar 6 and the end of a rib 6 thereunder to be projected into either slot when it is desired to remove the bar 6 from the ring 1.

The rib 6 on the bar 6 however is slightly less than the inside diameter of the ring 1*, so that the bar must be raised in order to project either rib into its corresponding slot, and yet permitting of a certain amount of lateral play of the bar.

A valve cap 9 is positioned above the member 1, being adapted to cover the same, and is provided with a packing ring 10 adapted to rest on the seat 1 projecting upwardly from the flange 1 of casing 1.

The member 9 is provided with a boss 11 tioned a member 12, which has a screw 13 extending downwardly therefrom and in- 1 tegral therewith, and which projects through a tapped hole provided in the bar 6.

The member 12 has an enlarged portion 14: above the boss 11 and overlapping the same, the boss being provided with a packing ring 145 at this point. The portion 14 is hollow, but has a pair of oppositely disposed V-shaped members 15 projecting therein, the points thereof being suitably spaced apart. A cover 16 is secured over the member 13, which cover by being squeezed under the member lt as shown at 16 is provided with a slot 17 therethrough, adapted to receive the rectangular lower end 18.0f a valve turning key 19 therein. This key is provided with a handle bar 20, and is held in a substantially rigid position while being utilized by means of a disk 18 secured to the key 19 above the member 18 and adapted to rest on the cover 16 when being used, being of a length sufficient to project above the usual hydrant hood or bypass pipe 21 ordinarily positioned around the concrete pipe 5 for a considerable distance above the same. A cotter pin 22 is placed through the screw 13 below the boss 11,. and impinges thereagainst.

The operation is as follows When it is desired to open or close the I valve, the portion 18 of the key is inserted through the slot 17, and the key is turned till the portion 18 bears against .the sides of the V-shaped projections in the member 13. By then continuing to turn the key, the valve will, of course, be opened or closed,

depending upon the direction of turning of the key. By reason of thefact that the clamping bar 6 is loosely mounted in the member 1 with regard to lateral .motion therein, it is evident that the valve cap 9 will always find a. perfect seat with the cas ing 1, no matter'if the tapped .hole 14 in the bar 6 is off center.

The packing rings 10 and 14 assure a watertight seat when the valve is closed. Should it be desired to remove the cap, the key is turned till the screw 13 is clear of the bar, when the key is lifted, and the cap is raised with it, it being only necessary to hold the key so that the portion 18 thereof bears against the under side of the cover 16, and is not-in alinement with the slot 17' therein.

The valve turning handle or key being re movable with the valve itself, permits of an. entirely unobstructed fiow of water through the pipe, and a greater volume may freely pass therethrough than is possible with a valve remaining secured in the casing. By this same means, the clamping bar may also be removed from the casing with the valve cap and screw when desired.

Thus, from the foregoing description it will readily be seen that I have produced such a device as substantially fulfils the objects of the invention, as set forth herein.

While this specification sets forth in detail the present and preferred construction of the device, still in practice, such deviations from such detail may be resorted to as do notform a departure from the spirit'of the invention as defined by the appended claims. 7

Having thus described my invention, what I claim as new and useful and desire to secure by Letters Ratent is 1. An irrigation valve including in combination with a concrete irrigation pipe, a casing having annular spaced and concentric flanges, the outside and inside diameters of the outer and inner flanges respectively being of the same diameters as those of the concrete pipe on which the casing is placed, whereby the concrete may be poured into and assembled with the same and a stand ard mold used for forming the pipe.

An irrigation valve including a me tallic valve casing, a valve cap adapted to seat against the upper edge of the casing, a screw rotatably mounted in the "cap, a key retaining portion formed with the upper end of'the screw, a clamping bar receiving the screw therethrough and loosely mounted in thecasing, and a key adapted to fit into the key retaining portion of the screw whereby the screw, valve cap and clamping bar'may be manipulated to raise and remove the'same from the casing at will.

- 3. In an irrigation valvehaving aicasing, a valve cap adapted to seat thereon, and. a screw .rotatably .mounted in the cap and projecting below the same, a clamping bar receiving the lower end of the screw therein,

the ends of the bar projecting. slightly un der the edges of the casing in .slotted bosses formedwith the casing, and the bar having ri bs on its underside terminating short of the slots whereby limited lateral movement of the bar may be had, the height of the slots in the bosses being sufficient to receive the ribbed end ofthe bar therein when the same is lifted and moved laterally whereby if the valve cap is raised off its seat and the screw then tilted from a vertical plane, the
