Mixing faucet using drawn metal parts

Claim 2

A body for a mixing faucet comprising: a tubular cylindrical casing open at the top and closed at the bottom by a plug; tubular supply pipes having segmental notches in their upper ends secured to the sides of said casing with the bottom of the casing secured to the bottoms of the notches and closing the sides of the notches; a mounting ring secured around the midportion of said casing in closing relation to the upper ends of said pipes and projecting radially therebeyond; said casing defining inlet ports opening to the upper ends of said pipes; a clamp bar secured to the bottom of said casing in projecting relation between said supply pipes and adapted to support clamp screws in opposed relation to said mounting ring; said casing having an outlet port formed through its side above said mounting ring; an annular groove formed around the exterior of said casing above said outlet port; said groove being adapted to coact with a retaining member for holding a core actuating cap member rotatably in position on the upper end of said casing; and flowed metal sealing and holding connections between the adjacent edges of said casing, said plug, said pipes and said mounting ring.

Claim 3

A faucet body as defined in claim 1 in which there is a post secured to said plug and said clamp bar and spacing the bar below said casing, and in which said groove is spaced substantially above said outlet port permitting the location of an annular base of a spigot to be mounted in rotatable relation around said casing and over the top of said ring.

Claim 4

A faucet body as defined in claim 1 in which said casing and said supply pipes are formed from drawn metal tubing.

Claim 5

A mixing faucet comprising: a tubular cylindrical casing closed at its lower end; a pair of supply pipes projecting downwardly below said casing and having segmental notches in their upper ends secured and sealed to the side of said casing along the edges of said notches and communicating with said casing through inlet ports formed through opposite sides of the casing; an outlet port formed through said casing in spaced relation above said inlet ports; a cylindrical core rotatably and slidably mounted within said casing and defining an axially extending central mixing chamber closed at each end; a lateral inlet passage formed in said core and rotatably selectively registrable with said inlet ports and axially selectively movable with said core into and out of registry with said inlet ports; a lateral outlet passage formed in said core and slidably selectively registrable with said outlet port when said inlet passage is in registry with said inlet ports; a vent tube extending through said mixing chamber and in sealed relation through the ends thereof to open to said casing above and below said core; delivery means mounted on said casing and defining a delivery passage communicating with said outlet port; a cap member mounted in rotatable relation on the upper end of said casing above said delivery means; and means connecting said cap member to said core to permit rotatable and axial movement of the core relative to the casing.

Claim 6

A mixing faucet comprising: a tubular cylindrical casing closed at its lower end; a pair of supply pipes projecting downwardly below said casing and having segmental notches in their upper ends secured and sealed to the side of said casing along the edges of said notches and communicating with said casing through inlet ports formed through opposite sides of the casing; an outlet port formed through said casing in spaced relation above said inlet ports; a cylindrical core rotatably and slidably mounted within said casing and defining an axially extending central mixing chamber closed at each end; a lateral inlet passage formed in said core and rotatably selectively registrable with said inlet ports and axially selectively movable with said core into and out of registry with said inlet ports; a lateral outlet passage formed in said core and slidably selectively registrable with said outlet port when said inlet passage is in registry with said inlet ports; a vent tube extending through said mixing chamber and in sealed relation through the ends thereof to open to said casing above and below said core; delivery means mounted on said casing and defining a delivery passage communicating with said outlet port; a cap member mounted in rotatable relation on the upper end of said casing above said delivery means; and means connecting said cap member to said core to permit rotatable and axial movement of the core relative to the casing.

Claim 7

A mixing faucet as defined in claim 4 in which there is a mounting ring rigidly connected around said casing above said supply pipes, said means forming said delivery passage including a spigot with an annular base rotatable about said casing and retained between said mounting ring and said cap member.

Claim 8

A mixing faucet as defined in claim 4 in which said mixing chamber is formed by a bore from one end of said core, and a plug closing the entry end of said bore, said vent tube having one end extending in sealed relation through said plug.

Claim 9

A mixing faucet as defined in claim 6 in which said plug and the lower end of said vent tube are located at the lower end of said core and within the closed end of said casing.

Claim 10

A mixing faucet as defined in claim 4 in which: said casing and said supply pipes are formed of cylindrical tubing; a plug closing the lower end of said casing; said supply pipes having notches formed in their upper ends receiving the sides and the adjacent portions of the lower end of said casing; a mounting ring secured around said casing in closing relation to the upper ends of said supply pipes; and soldered joints connecting and sealing the adjacent surfaces of said casing, said supply pipes and said mounting ring.

Claim 11

A mixing faucet as defined in claim 8 in which there is a clamp support secured to the bottom of said casing and adapted to support clamp screws in opposed relation to said mounting ring.
