VALVE.

Specification of Letters Patent.

Patented Nov. 7, 1916.

Application led September 6, 1913. Serial No. 788,486.

To all whom it may concern Be it known that I, GEORGE O. MILLER, a citizen of the United States, residing at North Tonawanda, in the county of Niagara and State of New York, have invented certain new and useful Improvements in Valves, of which the following` is a specification.

This invention relates to improvements in valves for faucets, and more particularly tobthat type of faucet known as Fuller bi My invention has for its object the provision of a valve of this type which is reinforced in a manner to thoroughly strengthen the same and prevent the wearing away of the yielding material; to so construct the same that the valve will retain its proper form under the pressure to which it is subj ected when placed in a bib; and to so reinforce the same that cutting of the yielding material will be prevented.

To this end the invention consists in constructing the valve of the usual formation, which is that approximating the shape of an acorn, and in reinforcing the same.

It further consists in providing a valve of this type with a reinforcing member of a formation somewhat similar to the body of` the valve and provided with a roughened surface to assure proper adherence thereto of the material forming the body of the valve.

It also consists in so forming the reinforcing member that the pressure necessarily applied to the valve when closing the same against its seat will be in'a direction atan angle to the edges of said reinforcing member, whereby cutting of the valve body is prevented and assurance is had of retaining the formation of said body.

It furthermore consists in the construction and arrangement of parts to be hereinafter described and particularly pointed out in the subjoined claims. Y

In the drawings,-Figure 1 is a side elevation of a Fuller bib valve, showing the same of the usual formation. Fig. 2 is a central longitudinal section through the same. Fig. 3 is a cross section taken on line e-e, Fig. 2. l

The valve, as stated, is of the usual circular formation in cross section having itsgreatest diameter at 5 and tapering from this point in one direction, as at 6, and in the other direction at a less angle, as at 7, to the seating end 8, which is curved.

This valve has its body-portion made of rubber or otherl suitable yielding material and is provided with a central bore 9 extending from end to end thereof to enable its being applied to the usual valve rod used in Fuller bibs.

10 represents a metallic or other suitable reinforcement which is preferably of circular formation in cross section and tapered to conform to the long tapered portion of the valve body and is embedded in the material forming said body but constructed so .that it terminates short of the ends thereof. For this reason it is entirely surrounded with the rubber or other material forming the valve body, which material is molded around it in any suitable manner. This reinforce--A ment or reinforcing member is in the form of a tapered thimble open at both ends and having the extremities bent inward, as at 11, 12, and in order to provide a secure bond between the same and the material forming the valve body, it has a rough or undulated surface preferably formed by slight indentations 13 created by pressing the metallic material inward to form the projections 14e on the inner face of the reinforcement, the exterior surface of said reinforcement having the appearance similar to an ordinary sewing thimble, but if desired may otherwise be roughened for the purpose mentioned.

As is well known, valves of Fuller bibs are subjected to considerable pressure when seating them against their valve seats and the yielding material from which they are made quickly wears away under such pressure due to the fact that the entire body of the valve is yielding in the direction of its length as well as inwardly toward the valve stem'to which it is secured. Owing to the peculiar formation of Fuller bib valves, it is essential that the valve body be yielding at least in a measure, but it is also highly essential that sufficient backing be provided toprevent undue wear of said valve body, which the small size of the valvestem does not afford.V My improved reinforcement assures retention of the 'valve body to its proper formation, and as it is embedded approximately centrally between the exterior surface of the valve body and the bore of the same it retains sufficient yielding qualities to properly seat against its valve seat without allowing its being compressed against said seat to such an extent as to inlos jure the same, as is common, and owing to the reinforcing member being circular' in cross section, the valve body is greatly stiffened. Moreover, the. tapering formation given this reinforcing member permits the material forming the body of the valve to yield in the direction of its length as well as inwardly toward the reinforcement.

By bending the opposite ends of the reinforcing member inwardly, as shown, there is no chance of the yielding body becoming cut at its ends when the valve is subjected to pressure by closing it against the valve seat and by reason of the small. indent-ations or roughened surface being provided on the exterior of said reinforcement, the ,tendency of the rubber creeping on the reinforcement is entirely eliminated.

lf, at any time the valve becomes worn, the formation of the same is retained along the nnworn portion, and crushing of the valve will not occur at any time. The valve may therefore be used for along period of time, sinceit wears in such a way that the metallic reinforcement will always serve as a proper backing for the yielding material outside of the same. V

Having thus described my invention, what l claim is,-

l. A. valve for bibs comprising` a yielding body having a central cylindrical bore extending from end to end thereof and a metallic reinforcing member somewhat shorter than said bore. embedded in said yielding body and encircling said centralbore.

2. A. valve for bibs comprising a yielding body tapered lengthwise and having a longitudinal cylindrical bore therein extending from end to end thereof, and a reinforcing member shorter than said bore embedded therein and similarly tapered.

3. A. valve for bibs comprising a yielding elongated body having a central cylindrical bore extending from one end thereof to the other, a metallic reinforcement embedded therein and extending from a point near one end of said body to point near the other end thereof, said reinforcing meinber having its ends bent at an angle to prevent cutting of the material forming the body when pressure is applied thereto.

A. valve for bibs com-prising-a tapered body formed ofyielding material having a central cylindrical bore arranged lengthwise therein and extending from end to end thereof, a circular metallic reinforcing member somewhat shorter than said bore embedded in said yielding body and having its wall arranged at a slight angle to said bore.

5. A valve for Fuller bibs comprising an elongated body-portion formed of yielding material having a central cylindrical bore extending from end to end thereof, a circular metallic reinforcing member somewhat shorter than said bore embedded in said body portion and having its opposite ends bent inwardly. p

6. A valve for bibs comprising a tapered body-portion formed of yielding material having a central `cylindrical bore extending A:om end to end thereof, a tapered circular reinforcing member somewhat shorterthan said bore embedded in said yielding bodyportion and having inwardly bent ends and a roughened exterior surface, for the purpose set forth.

7. A valve for .bibs comprising a tapering body formed of yielding material vhaving a central cylindrical bore arranged lengthwise therethrough and extending from end to end thereof, a metallic tapered reinforcing member somewhat shorter than said Vbore conforming in cross section to the formation of said body and having roughened interior and exterior surfaces, for the purpose set forth.

8. A .valve for Fuller bibs comprising a tapering body-portion formed of yielding material havingl a central cylindrical bore arranged lengthwise ltherein and extending from end to end thereof, and a tapered reinforcing member of circular formation in lcross section having opposite ends bent inwardly,v said reinforcing member being somewhat shorter than said bore and provided with exterior indentations and interior projections, for the purpose set forth. 9. A valve comprising an elongated body portion formed of yieldingmaterial having a central cylindrical bore extending from end to end thereof, and a metallic reinforcing member embedded in said body portion and arranged so that when closing said valve against a seatrthe pressure will be in a. direction at a slight angle to the exterior surface of said reinforcing member.

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