FREELAND D. LESLIE, OF MILTON, MASSACHUSETTS.

REMOVABLE VALVE SEAT FOR BALL COCKS.

Application filed January 27, 1921. Serial No. 440,303.

To all w hom t may concern Be it known that I, FREELAND D. LESLIE, a citizen of the United States of America, and a resident of Milton, in the county of Norfolk and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Removable Valve Seats for Ball Cocks, of which the following isa specication.

This invention relates to ball cocks and more particularly to a removable valve seat therefor, the object of the invention being the provision of a device of this character which will divert the water passing through the same so that the noise of the rushing water will be reduced toi a minimum.

The invention consists in a tubular valve seat having inwardly extending ribs in staggered relations to each other and preferably at different distances apart and at different angles relatively to each other.

The invention further consists in certain novel features of construction and arrangement of parts which will be understood readily by reference to the description of the drawings and to the claimsto be'hereinafter given. y

For the purpose of illustratingthe invention, one preferred form thereof is illustrated in the drawings, this form having been found to give satisfactory and reliable results although it is to be understood lthat the various instrumentalities of which the invention consists can be variously arranged and organized and the invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described except as required by the scope of the appended claims'.

Of the drawings:

Figure 1 represents a vertical section of a ball cock provided with a removable valve seat member embodying the principles of the present invention.

Figure 2 represents an enlarged vertical section of the removable valve seat member.

Figure 3 represents a section thereof on throughout the several figures of the drawings.

In the drawings, 10 is a hollow body portion having an inlet 11 and outlet 12.

Within the inlet 11 is disposed a tubular member 13, the upper end of which is pro-4 vided withan annular valve seat 14 and the opposite end of which is flaring as indicated at 15.

This Haring end 15 of the tubular member 13 lits into the cone-shaped outer end of the inlet 11 and thereby prevents inward movement of the tubular member 13.

Against the outer end of the flaring portion 15 of the tubular member 13 rests the end of a pipe 16 coupled to the body portion 10 by means of the member 17.

The end of the pipe 16 bearing against the flaring end 15 of the tubular member 13 prevents any outward movement thereof.

In alinement with the inlet 11 and reciprocable in the body portion 10 is a plunger 18 to the inner end of which is secured a packing member 19 by means of a screw 20.

This packing member coacts with the seat 14 to close the inlet and prevent water passing through the chamber 21 to the outlet pipe 12.

The plunger 18 has separated ears 22 extendin upwardly therefrom in which is revoluly mounted a pin 23.

The body portion 10 is provided with separated ears 25 between which is disposed a rocking member 26 having a lateral arm 27 disposed between the ears 22.

This arm 27 has an open ended slot 28 formed therein through which the pin 23 extends.

The rocking member 26 has an elongated `opening 29 formed therein through which extends a pin 30 mounted in the ears 25.

In the upper end of the rocking member 26 is disposed the usual float rod 31 secured therein by the clamping bolt 32.

The body portion 10 is provided with a Hange 33 by which it may be secured to the usual flushing tank in any desired position.

l/Vhen the water is low in the flushing tank the lower end' of the lloat on the rod 31 will cause the member 26 to be moved about the pin 30 and lift the plunger 18 from the seat 141 and permit the passage of water through the pipe 16, tubular member 13 and outlet 12 and as soon as the water rises sufficiently the plunger will be moved downwardly until the packing member 19 is forced solidly against the seat 14.

The removable member 13 is provided with a plurality of ribs Btextending in-v wardly toward the axis of said tubular member and alternately disposed on opposite sides of the member.

The ribs are at diiferent angles to the axis of the tubular member 13 and those at the opposite ends or" said tubular member are inclined inwardly toward each other as clearly indicated in Figs. 1 and 2 of the drawings.

Preferably the inner ends of the blades 34 are in alinement with the centra-l axis of the tubular member 13 as shown in -the drawings but it desired they may be extended lso that the inner ends are disposed between the inner ends of two oppositely disposed ribs.

By constructing the tubular member in this manner with the plurality of inwardly extending staggered ribs a zigzag passage is provided through which the water must flow when the plunger 13 is lifted from the'valve seat 14C.

This zigzag passage is of much greater length than the length of the tubular inember.

Owingn to the inclination of theribs '34, the water flowing through the removable valve seat member is retarded to a certain extent by these delecting ribs.

This results in the water flowing' through the removable valve member silently and thereby overcomes the objections to `ball cocks ofthis character now in general use in which considerable noise is made byithe water rushing` through. the ball cock from the inletpipe to the discharge pipe...

It is believed that the operation and many advantages of the invention will be understood readily without further description.

Having thus described my invention, I claim- 1. In a device of the class described, a tubular member provided with a. valve seat at one end and having a plurality of inwardly extending ribs at varying,- distances apart.

2. In a device of the class described, a tubula-r member provided with a valve seat at one end and having a plurality of inwardly extending ribs at different angles relatively to each other.

3. In a device of the class described, a tubular member provided with a valve seat at one end and havinga plurality oic ribs extending inwardly at an angle to the axis thereof with those at the opposite ends inclined toward a point intermediate the length of said member.

Ll. In a device of the class described, a tubular member provided with a valve seat at one end and having a plurality of inwardly extending ribs at various inclinations and alternately disposed on the opposite sides of said member.

5. In a device of the class described, a tubular member provided with a valve seat at one end and having formed integral therewith a plurality of inwardly extending ribs alternately disposed on the opposite sides of said member with their inner ends at the axis ot" said tubular member.
