Abstract
An improved lever head for a single handle mixing faucet of the type wherein the hand lever is brought out of the body at right angles to the valve slides is described. Volume adjustments are made by swiveling the handle from side to side whereas mixing adjustments are made by rotating the hand lever about its longitudinal axis.
Claims18
In a lever head for a single-lever mixing valve for sanitary use for regulating the mixing and volume flowing of cold and hot water with a hand lever which is pivoted substantially at right angles to a valve slide, the improvement wherein said valve slide is mounted for axial displacement and swinging movement transverse to said axial displacement in a plane thereof, and the control settings for adjusting the mixing ratio of cold and hot water are produced by turning the hand lever about its longitudinal axis to effect said swinging movement independently of said axial displacement and the control settings for adjusting the volume flow are produced by swivelling the lever about a pivot on the body to effect said axial displacement independently of said swinging movement.
A lever head for use with a mixing valve having a head piece movable reciprocably in an axial direction and pivotally transversely of said axial direction to control the position of a valve, said lever head comprising:
- a body covering said headpiece;
- a hand lever comprising a swiveling lever, means for pivotally coupling said lever to said body to permit swiveling motion about a swivel axis in a fixed plane relative to said body, a spindle extending through said swiveling lever and rotatable therein, and an adjusting knob coupled to one end of said spindle;
- said spindle being coupled to said head piece by a gear drive;
- and
- whereby swivel motion of said swivel lever moves said head piece reciprocably in said axial direction and rotational movement of said spindle moves said head piece transversely and independently of the movement of said head piece by said swivel motion.

- and
- whereby swivel motion of said swivel lever moves said head piece reciprocably in said axial direction and rotational movement of said spindle moves said head piece transversely and independently of the movement of said head piece by said swivel motion said hand lever further comprising a head having a spherical face, said headpiece being adapted to engage said head, said head being guided parallel to said swivel axis by a sliding shoe in a sliding guide, and said spherical head having a transverse slot positioned parallel to the sliding surfaces of said sliding shoe and in which said spindle is mounted, whereby rotary motion of said spindle causes transverse motion of said sliding shoe.
