Dial for fluid temperature and flow control
FIG. 1 is front elevational view of a dial for fluid temperature and flow control showing my new design;
FIG. 2 is a front perspective view; and,
FIG. 3 is a rear perspective view thereof.
The edge views are of conventional thickness throughout the drawing.
The characteristic feature of the design resides in the combination of the following elements: a disk; two diametrically opposed arc of surface ornamentation on one side of the disk, adjacent the circumference of the disk; each arc comprising a series of radial marks of equal circumferential separation, which gradually increase in length from one end of each arc to the other, increasing in the same direction on both arcs; surface ornamentation, visually representing temperature, adjacent one of the arcs; surface ornamentation, visually representing flow, adjacent the other arc.
