VALVE.

Specification (if Letters Patent.

Patented Get. 15, 1912.

Application filed February 17, 1912. Serial No. 678,312.

To all whom it may concern:

Be it known that I, VVILBUR F. BUDLoNG, citizen of the United States, residing at Berea, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Valves, of which the following is a specification. 1

The object of my invention is to provide a valve construction adapted especially to spraying apparatus employing caustic or corrosive chemicals and in which the inter-j nal parts may be assembled in using rela= tion and handled as a unit both for putting the same in place and in removing them from the casing and thus avoid separate handling of said parts.

In my prior invention, Patent No. 1,001,246, on which the present construction is 'an improvement I provided for the eliminae tion of all interior screws or screw parts and for'the simplification of the device in other particulars, but I found, from practice, that the manner of assembling did not always secure perfect fitting and alinement of the parts. I also found that in demounting the parts the valve proper and valve seat remained in the valve chamber or casing and were not conveniently removed. Also that when demounted the parts were separate and liable to become lost. In my present invention all these objections are overcome and the parts are further simpli lied and secured together in a practical and economical manner and may be assembled in perfect fit and alinement under the immediate observation of the operator, and be removed as a unit and cleaned and replaced in like manner without disturbing the lit or alinement.

In the drawings, Figure 1 represents a sectional elevation of a valve construction embodying my improvementand in which a conventional type of ball-valve is shown. Fig. 9. represents a valve cage or crib with the valve and valve seat therein. Fig. 3 is a sectional elevation of the valve casing or chamber, and Fig. 4 is a bottom view of Fig. 2. Fig. 5 is a sectional plan looking down on line a w of Fig. 1, the adjustable cage being shown in a different position.

The valve casing or chamber 0 is adapted to receive all the other parts and is provided with an inlet port 2 at its bottom and an outlet 3 at its side and top and an opening 4 in its top, as formerly, besides having opposite lugs or projections 5 at about its middle and side, and an annular channel 6 about the top opening at for a gasket. The ball valve '0 is confined within the cage 6, and the said cage is of a size to enter snugly through the top opening 4: of the casing and is closed across its top and provided with a flange 7 which. overlaps the casing and serves as a cap or cover therefor. The said cage is provided with a ring-shaped bottom portion which has an annular inside recess, and a correspondingly shaped valve seat (Z is located in said recess and in this instance is shown as beveled atboth outer edges so as to be reversible, which is desirable when the seat becomes worn. A rubber, lead or other suitable gasket 9 is employed to make 5 a fluid tight closure between the cage and the bottom of chamber 0, and a similar gasket h is provided for the channel 6 in the top of the chamber or casing to seal the flange 7 of the cage fluid tight thereon. A

yoke n is of a size adapted to reach across the top of the casing and its cover and has teeth 8 on its side extremities adapted to engage beneath the lugs 5, and a cam m is pivotally mounted on the said yoke and-* adapted to bear upon the said cover or top of the cage and thus forcibly lock the casing and cage together in water tight relations. A screw might serve the same purpose but the cam is more convenient. The gasket 9 is substantially wedge shape and adapted to enter the substantially V-shaped space formed between the beveled edge of the cage and the bevel of the seating ring h, whereby the said gasket is made to serve the double. purpose of wedging. the parts together and making a fluid tight joint. This construction and arrangement of the parts also makes them unitary for handling and avoids the objection of fishing the valve and its seat out of the casing after the cage has been removed, as was formerly necessary. This is very important in spraying devices especially because of the caustic or other severe character of the chemical and the consequent objection to handling the device at all and especially separately. Frequently, in fact, the casing is filled with the liquid when the valve mechanism has to be removed and the recovery of the parts by an inexperienced person is liable to become embarrassing. But by having the said valve seat temporarily locked to the cage it can be removed with the crib and carry the valve with it, which is very desirable. It will be 'noticed, also, that the cage does not come quite down to the bottom of the casing nor the flange 7 to the top of the casing when the gaskets intervene, so that there is room for the compression and tightening of gaskets and which, in any event, must be of such proportions as to perfectly seal the parts at both places and with substantial uniformity against possible leakage.

The parts are handled by assembling the crib or cage and the valve and valve seat and gasket 9 as seen in working position Fig. 1, and then placing them in the casing as a unit. The wedge shape of the gasket serves especially to fasten the valve seat ring in or on the cage with such security as makes such handling possible, while it also serves as a seal when under compression through the yoke to prevent leakage about the said seat.

By spacing the panels or bars I) of the cage apart at varying distances, as the space 8 compared with-the space 9, the valve '0 will be automatically rotated more or less during the operation of the machine. For example, suppose the space 8 to be located more or less nearly opposite the exhaust 3 of the easing as shown in Fig. 5 and the liquid is rushing in from below. The freer exit of the liquid from or through space 8 than through the more contracted spaces 9 will actually induce a perceptible rotation or turning of the ball as it rises and thus it will always present a different portion to the seat and prevent undue wear upon any one portion thereof.

What I claim is:

1. In a valve mechanism, a casing and a cage therein having a ring-shaped bottom provided with an annular recess, a ringshaped valve seat occupying said recess, said cage and seat having a substantially V-shaped space between them and a substantially wedge-shaped gasket adapted to wedge into said space and lock said parts together and to seal the valve seat as to both the cage and the bottom of the casing.

2. In a valve mechanism, a chamber with an inlet and an outlet and a cage therein having a bottom provided with an annular recess on its inside, a ring-shaped valve seat occupying said recess, and a gasket adapted to wedge into the space between the wall of said recess and said valve seat to lock said parts together and to seal the valve seat as to both the cage and the bottom of the chamber.

3. A. valve casing and a cage therein having an annular recess in its bottom, a valve in said cage and a ring-shaped seat for said valve removably secured in said recess and having beveled outer edges, thereby making the said seat reversible, and a gasket adapted to engage about the edge of said seat.

4. A valve mechanism having a casing and a cage therein provided with panels spaced apart at diflerent intervals, whereby a greater space remains between two given panels than between other two, a ball valve adapted to float in said cage and a seat there for at the bottom of the cage and the said casing having an inlet in its bottom and an outlet on a plane relatively above the said ball, whereby when the liquid flows through the said crib the ball will be automatically turned by the action of the liquid,

5. In a valve mechanism, a casing having an opening in its top and an inlet and outlet in its side and bottom respectively, a cage having openings of varying size therein, said cage being seated upon and within said casing apart from its side walls.

In testimony whereof I affix my signature in presence of two witnesses.
