VALVE.

SBEQIFIGATIQN forming part of Letters Patent No. 252,195, dated January 10, 1882.

' A Application fned october 11, issn. (Nomad.)

To all when?, it may concern:

Be it kno'wnthat 1, WILLIAM DECKER, of Colfax, county of McLean, State of Illinois, have invented a new and useful-Improvement 5 in Valves for Control-lin g the Flow of Water,

of which the following is a specification.

My invention relates to an improvement'in valves, the object being to providean article of this character which shall be adapted to au- 1o tomatically control the flow of water into a vessel, and which shall combine with simplicity and cheapness of construction durability in use.

With these ends in view my invention consists in certain detailsin construction and comt 5 binations of parts, as will hereinafter be described, and pointed out in the claims.

In the accompanying drawings, Figure l is aview in vertical section of a water-vessel provided with a valve constructed in accordance 2o with my invention, and Fig. 2 is a plan view thereof with the floating weight removed.

A represents a vessel of any desired form, and C a pipe supplying itwith waterfrom any convenient source, D is a valve-chamber, into which the said pipe G discharges its contents, whichniowfrom thencentothevesselAthrough an egress-port, d, formed in the upper wall of the chamber. A hinged valve directly attached to the interior wall of the said chamber is 3o adapted, as will be hereinafter described, to automatically open and close communication between it and the vessel A by covering, under certain conditions, the egress-port d.`l

A oat., F, of any desired size, construction,

or material, and arranged to be floated by the water in the vessel A after it has` attained a predetermined height therein, is connected to the hinged valve E, described above., by a rod, e, or any suitable equivalent therefor. It is 4o desirable that the connection between ,the said valve and rod be a pivotal one, in order that as the valve is opened and closed the rod which actuates it in such motion may always reciprocate in a vertical plane, while the connection between the said rod and oat should be vertically adjustable to permit the regulation of the height to which the water must rise in the vessel A before the float isV buoyed thereby.

i In the fulfillment of this last-recited principlem of construction the float may be centrally 5o pierced with an interiorly screW-threadedjapevtilre and the upper end of the rodscrewthreaded 5 or any other equivalent method of adjustment may be resorted to.

G is a bar or guide interposed between the float and the top of the valve-chamber D, and adapted to fulfill the twofold function of securing to the guide a vertical reciprocation and of supporting the float when not buoyed by water in the vessel A, and bearing a weight 6o which would otherwise fall on the valve E. In order that the bar may fulfill this function, it should be located a little below the water-line at which the float is buoyed. In the fultillment of its rst-named function it is provided with a perforation exactly registering with the egressport ol, and arranged to receive the guiderod c.

It is obvious that many devices for fulfilling the designs of the guide G may be adapted in 7o lieu thereof. For instance, a frame secured to the side of the valve-chamber may be arranged to extend over the top thereof and guide the rod e and support the unbuoyed float. It is particularly necessary that a guide of some character be employed, as otherwise the oat, in changing its position on the water, which it is left free to do, will tend to wrench the hinge-bearing of the valve.

Havingdescribed myinvention, I will briey 8o set forth its mode ot' operation. Supposing the vessel E to be empty, if water be admitted to the valve-chamber D through the pipe C, it

vwill dow from said chamber into the vessel A through the egress-portal. When water nearly fills the vessel A the float F will bebuoyed thereby, and slowly rising close the port d by means of valve E, which it operates by means ofrod c. The valve E will remain closed until the subsidence of the water lowers the 9o tloat, which will, in falling, open the valve and again allow the water to pour into the outer vessel.

It is not necessary that the vulve mechanism should be located in the receptacle from I9 5 which the water is withdrawn; but it may as ,ter-pressure.

.mentof them.

well be located without and connected with it by suitably-arran ged water-conduits.

When the. waterows into the valve-chainber under much head it will tend to close the valve in antagonism to the weight ot the oat. In such case the Weight of the float should be regulated in proportion to theforce ofthe Wa- Among the advantages claimed forthis form of valve over others may be mentioned that of' cheapness, as it does not require the nice atb justment necessary to the operation of circular and hemispherical valves; the advantages-of durability and simplicity, the parts being few and -simple and the'adjustment such that the wear on the parts is very slight, and the iin.- portant advantage of surety of action, the arrangement ofthe parts precluding a displace- I would have it understood that I do not limit myself to the exact construction of parts` shown 'and described, but hold' myself at'libto closey upwardly and cover said port, of a cat and a stem secured at one end to the oat and at the other end hinged to said valve, substantially as set forth.

2. A supply-pipe, C, receptacle A, chamber D, with ports c and d, and oating weight F, in combination with a hinged valveattachedto thc inner surface ot' chamber D near the egress-port d, and suitable connections between the valve and floating weight, as set forth.
