CLYDE L. CRAIG, OF WASHINGTON COURT HOUSE, OHIO.

FLOAT-VALVE.

Application filed January 18, 1917. .Serial No. 143,071.

To all whom it may concern:

Be it known that I, CLYDE L. CRAIG, a citizen of the United States, residing at Vvashington Court House, in the county of Fayette and State of Ohio, have invented certain new and useful Improvements in Float-Valves, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improvements in float valves and it is an object of the invention to provide a device of this general character having novel and improved means whereby the float may be caused to ride upon the surface ofthe water onto be submerged to any predetermined extent in accordance with the particular requirements of practice.

Furthermore it is an object of the in vention to provide a novel and improved device of this general character whereby the float may be maintained submerged so that the same will. be protected against inter ference which would possibly be imposed thereupon by the elements, such as wind, snow, ice, or the like in the event the boat should ride upon the surface of the water.

A still further object of the invention is to provide a device of thisgeneral character including a float operatively engaged with the valve member together with a balancing member operatively engaged with the valve member for controlling the position of the float relative to the water level so that said float may be caused to ride upon the surface of the water or be submerged to any predetermined depth when the valve member has been seated to close the water supply.

It is an object of the invention to provide a novel and improved device of this general character including a buoyant body operatively engaged with a weighted valve member whereby the valve will be caused to work against the pressure of the water supply when the buoyant body is not in action so that the buoyant body may be submerged before the water supply is completely cut off. l

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved fioat valve whereby certain important advantages are attained and the device is rendered simpler, less expensive and Specification of Letters Patent. Patented Aug, 10 1920 otherwise more convenient and advanta geous for use, all as will be hereinafter more fully set forth; r

The novel features of the invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein is disclosed a v ew partly in elevation and partly in section illustrating a float valve constructed in accordance with an embodiment of my invention, a coacting tank being shown in fragment. As disclosed in the accompanying drawings, denotes a tank of: predetermined dimensions and for any particular. purpose. Arranged within the tank T at any desired point and preferably adjacent the bottom thereof is the stand pipe 1 in communication with a suitable source of water supply. Positioned within the stand pipe 1 is the valve member 2 which is adapted to control the discharge of the water through the pipe 1 into the tank T.

Operatively engaged with the valve member 2 is the stem 3 which, as herein disclosed, is vertically extended above the up- .per or discharge end of the stand pipe I,

and the free end portionof the stem 3fis returned, as indicated atlr, and then extended laterally, as at 5, said laterally extended portion being of such a length as required by the necessities of practice.

Slidably mounted uponthe portion 5 is the poise 6 of predetermined weight and which is fixed in itsdiiferent positions upon the portion 5 through the medium of the binding screw 7. At this time I wish to state that I do not wish to be understood as limiting myself in anyway as to the character of the poise 6 or the manner whereby said poise is mounted or adjusted relative to the portion 5 of the stem 3, although in practice I have found that the arrangement hereinbefore described and as illustrated in the drawings serves with a maximum of efficiency.

The returned portion 4 of the stem 3 affords a loop or eye which permits a suitable connection with the stem 3 of the flexible member M of a predetermined length and which has its outer end portion suit ably connected to the buoyant body, or float 8.

.ride upon the surface of the water when the flow through the stand pipe 1 is completely stopped, However, it is of especial import that the float or buoyant body 8 be submerged especially when the tank is of such a character as to be employed in the open, as for agricultural or stock purposes. It is thought to be self-evident that when the float or buoyant body 8 is submerged no interference is. offered thereto by the elements, such as wind, snow, or ice.

The depth to which the float or buoyant body 8 will be submerged can be readily regulated by the extentof outward adjustment of the poise 6 upon the portion 5 of the stem. 7

When the float'or buoyant body 8 is at nearly the limit of its upward movement, the member Mvvill serve as a fulcrum for the stem 3. The poise 6 carried by the portion 5 of the stem 3 initially maintains the stem 3 angular relative to the longitudinal axis of the stand pipe 1 upon the rise of the water level in the tank and when the float or buoyant body 8 has rendered the member M substantially taut and the member 8 is at nearly the limit of its upward movement the marginal portion ofthe valve 2 will contact with a portion of its seat arranged at the top of the stand pipe 1. The force of the water passingupwardly through the stand pipe 1 will coact with the valve to gradually overcome the resistance of the poise 6 and completely force the valve 2 into closed position. The period of time however, required to completely close the valve member 2 permits the discharge of a sufficient amount of water within the tank 2 to submerge the float or buoyant body 8. The water escaping from the stand pipe 1 will also exert additional pressure upon the disk 9, to be hereinafter referred to, or direct upon'the float or buoyant body 8 whereby the proper closing of the valve member 2 is further assured.

I also find it of advantage in practice to suitably fix to the stem 3 at a predetermined point exterior of the stand pipe 1 the disk 9, said disk being of such diameteras to 0bstruct the flow of water discharged from the pipe 1 and deflect the water so that the water as discharged will not be thrown above the tank T. The use of this disk 9 is of particular advantage when' the stand pipe'l is in communication with a source of water supply of high pressure, such as .main pressure.

'Tnterposed in the stand pipe 1 below the valve member 2 is the check valve 10 herein disclosed as of a flat type and provided at its axial center with the weight 11 to facilitate the maintenance of said check valve 10 in its closed position.

The use of the check valve is of importance when a plurality of tanks are employed and in ,connection with a common source-of water supply and wherein said tanks are at diflierent levels as itwill at once he self-evident that the water within the tank T will be held therein should a second tank at a lower level beemptied.

From the foregoing description, it is thought to be obvious that a float valve constructed in accordance with my invention is of an extremely simple and comparatively inexpensive nature and is particularly well adapted for use by reason of the convenience and facility with which it may be assembled, and it will also be obvious thatmy invention is susceptible of some change and modification without material. departure from the principles and spirit thereof and for this reason I do notwish to be understood as limiting myself vto the precise arrangement and formation of the several parts hereinshown in carrying out my invention in practice, except as hereinafter claimed.

It will also be at once apparent that the poise 6 or its mechanical equivalent will serve to operate or prevent the valve memher 2 being held in closed position under the influence of the water pressure passing through the pipe 1 when the buoyant body or float .8 is not in action as the poise 6 serves to tilt the valve member 2 against the water pressure.

I claim: 1 I

In combination with a valve member and its seat, a buoyantbody operatively engaged with the valve member, and means carried by the valve member for retarding the seating of the valve'member under the influenceof the buoyant body to submerge the buoyantbody before the Jvalve member is in close contact with its seat. 7

3.
