Knight's American mechanical dictionary : a description of tools, instruments, machines, processes and engineering, history of inventions, general technological vocabulary ; and digest of mechanical appliances in science and the arts . ank on a ver-tical axis common to all. This carries a compoundstop-cock, which a<lmits the water to and dischargesit from each compartment when filled. Paytons meter ((, Fig. 2970) contains two S-shapedarms, whose extremities during rotation are in closecontact with each other and with the sides of thebox. The arrows indicate the direction of the cur-rent. Similar devices are shown under ; Rotary Pump. In Cochranes meter for measuring liquids underpressure, the measurement is effected by a pivotedvessel resembling a double scoop, which tilts anddischarges when either side is full. A bent leverbelow tills is tilted back and forth at each move-ment of the scoop, actuating the registering mechan-ism. Atwells cylindrical case has a piston E whichturns on an axial shaft communicating motion tothe register, and cariying an arm which, at the end LIQUID-METER. 1328 LIST. of each stroke, ulmuges a cylimliical valve F so asto cause tlie wutei- to alteiiuitely enter and discharge.

In Fig. 2972, a watcr-whecl within a pipe is con-nected to a register to indicate tlie How of How is regulated by a sliding-valve. In Youngs spirit-meter, Hoats G in the measur-ing-chambers are attached to each end of a pivotedbeam. The alternate downward motion of the Hoats,as the chambers are discharged, diverts the induc-tion How from one to the other. The Hoats G andtinir valves occupy two chambers, and arc suspend-ed to opposite ends of the oscillating beam E. Thevalve-stems have a limited sliding motion in the Fig. 2D73. Spiral- Vane Meter.
