W. G. ESTEP FLOAT CONTROLLED VALVE Reissued Nov. 3, 1931 =UNITED STATES PATENT OFFICE WILLIAM G. 'ESTEP, 0F DUQUESNE, PENNSYLVANIA, ASSIGNOR OF ONE-THIRD TO ROBERT HAWK AND ONE-THIRD TO JOSEPH GONLIN, 0F DUQUESNE, PENNSYLVANIA- FLOAT CONTROLLED VALVE Original No. 1,804,093, dated- May 5,1931, Seria11N0. 42 1,004, filed January 15, 1930. Application ,for reissue fil ed July 28, 1931. Serial No. 553,664.
This invention relates to a float controlled valve designed primarily for use in flush tanks and the like.
It is an ob'ect of the invention to provide a valve t e casing of which has means for supporting and guiding a float actuated lever used for actuating the .valve. v
Another object is to provide a valve which will be held to its seat by the elevated float in the tank being supplied with water and also by the pressure of water from the sup- P y p p A further object is to provide a simple and ellicient means for protecting the working parts of the valve, this means being easily removable when it is desired to obtain access to said parts.
With the foregoingand other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.
In the accompanying drawings the preferred form of the invention has been shown.
In said drawings:
Figure 1 is a vertical longitudinal section through the Valve casing and adjacent parts, a portion of the float being shown connected thereto.
Figure 2 is a bottom plan view of the structure.
Figure 3 is a section on line 3-3, Figure 1.
Figure 4 is a section on line l4, Figure 1.
Referring to the figures by characters of reference, 1 designates the body portion of the Valve casing which is preferably formed of metal, or porcelain, or other strong ceramic material. Extending from this body portion is a tubular stem 2 formed integral therewith and exteriorly screw-threaded as shown at 3. A bore 4 in the stem is provided at its inner end with a tapered seat 5 located at one end of a passage 6. This passage opens through the body portion 1.
Formation one face of the body portion 1 are spacedlugs 7 between which is mounted one end of an elongated curved lever 8 held guide between which a portion of the lever 8' 1s adap. ed to slid-e.
At the point beween the pivot lugs 7 and the guide ears 10 the lever 8 is formed with a slot 12 into which projects the reduced end 13 of a valve stem 14. This reduced end is attached to the lever by means of a transverse screw 15 or. other suitable pivot device. The stem is cut away longitudinally as shown particularly at 16 to provide longitudinal clearances between the stem and the wall of the passage 6. At that end remote from the lever the stem 14 is provided with a conical enlargement forming a valve 17 which is adapted to fit snugly against the seat 5. This valve may be formed in its large end with a kerf 18 whereby it is possible to grind the valve to its seat and insure a tight fit.
For thepurpose of protecting the pivot lugs, the guide ears, and the adjacent parts,
the body portion 1 of the valve casing is pro-I vided with a tight fitting cap 19 of a metal which will not corrode and this cap has a slot 20 extending thereinto from its edge within which the lever 8 is adapted to work. The slot is of such length that sufiicient clearance is always provided along the lever to permit,
the flow of water passing through the passage 6 when valve 17 is unseated.
The cap can be held to the body portion 1 by frictional engagement therewith although,
under some conditions, it might be advisable to use small screws or the like for holding it in place. Ordinarily, however, the cap is made with suflicient resiliency to cause it to grip the body portion 1 so that it will not become accidentally detached therefrom.
A float, a portion of which has beenindicated at 21, can be connected to lever 8 by any suitable means. For example, a stem 22 can be extended from the float and adjustably and detachably seated within a split sleeve 23 provided at one end of thelever 8.
. In practice, the stem 2 is inserted into an opening 24 formed. in the wall 25 ofthetank to be equipped with: this invention. A gas ket 26 of rubber or other suitable material is arranged on the stem between wall 25 and 10 body portion. 1 so that when 'a-nut 27 mounted. on; the threaded portion. of; stem 2*. is screwed against the wall 25, the washer or gasket 26 will be compressed and prevent leakage. Thereafter a supply pipe 28 can pling29.
When. the tank to which the. devicefis appliedrequireszfilling the float 21 andthatendofgthelever 8 towhich it is connected will be held. at'their. lower extreme. positions; Consequently, lever 8 will thrust against the stem. 1a. and. hold. valve 17 unseated. Thus water will be free. to flow around the valve and. along passa e 6: to the interior: of cap 19.. from. which. t will. escape through the slot .2Q intothetank. Astthe level of the liq.- uidin. thertank rises, the float will be gradually elevated and will pull: on the. end of lever 8. Thus the lever will draw valve 17 toward itsseat where. it will be heldnot only by. thefloatoperated lever but. also by the pressure back of the-valve from supply pipe, 28...
is claimed is:
1.. A. device of the class; described includ-- ing a body portion having a. tubular stem 0pm, therethrough, there, being a seat in, the stem,.diametrically opposed. ausof. pivot lugsand: gl i e ears on.the. bo y portion, a 40, floatvactuated. lever: pivotally mounted. be-
' tween. thelugs. and slidable between. the. ears, avalve adapted. to. fit. snugly upon the. seat,
be connected to the stem 2' by a, suitable cou and said slot constituting an outlet for liquid released by the valve when unseated.
3. A device of the class described including a body portion having an integral stem, there being a bore in the stem opening ,throughthe body portion andhaving a seat,
lugs integral with. the body'portiom, guide ears integral with the body portion, a lever extending between the ears and between the ing a body portion. having a tubular. stem opening therethrough, there being a. seat in.
. the stem, a float actuatedlever pivotally connectedto the body portion, means on the body portion for sliding engagement by the lever toguide it, a valve adapted to fit snugly upon the-seat, a stem projecting therefrom through the body and pivotally connected. to the lever adjacent. to the guiding means, and. a; protecting cap engaging the body portion and housing said guiding means and the ad'- jacent portionv of the. lever, there being an openingfin the cap in which the lever is movably mounted, said opening constituting, a liquid outlet.
In testimony that I claimthe foregoing as my' own, I have hereto afilxed my signature.
