  • the general objects of the invention are to provide a-water meter or measuring device adapted to operate under all conditions of temperature'and service. and with water at all fluid temperatures whether boiling hot or cold andtorpvide a nutating piston for path -for-the circulation-ofthe fluid through the gear-train and in this-manner to' attain immunity fol-the gearm from the action of electrolysis or from ga' vanic action inci-' dent to their immersion in dead or lifeless water such as accumulates about the gearing in the main case in the ordinary forms of construction.
  • a further object is-toprovide forms of main ca'se, measuring or piston chambergand crown frame, and bearing plate for the gear train, attached directly to the measuring chamber and so arranged that all the interior and working parts can be removed in one assembled'ma'ss, and hence increasethe accessibility of all parts and their adaptability to adjustment and repair.
  • This form of construction also permits reversal ofthe motor in any position without interfering with its use.
  • Figure 1 11s acentral vertical section-of the improved device;
  • Fig. 2 is aside view of the measuring origiston chamber showing inlet and outlet ces therein, and radial partition;
  • Fig. 3 -1 a horizontal transverse. section through the main case and pistonichamber-showi-n relative location of theinlet and outlet onfices;
  • Eig. 4. is a plan view of the controlling gear-train and the crown frame and bearing plate arranged for the support ofthe same;
  • Fig. 5 is a vertical sectional view of the crown'frame and bearing plate Showing one of the screw threaded s lndles, adapted to afford. adjustment fort e renewal of the bearing surfaces.
  • the bottomcover-QO is preferably breakabl so that the-measuring chamber and case will not be destroyed at a low degree of temperatune.
  • the entire structure may be mounted upon base members 40 by means of bolts 41 which ass through said'base these bolts-and bear against said lugs to hold the case upon the base members 40.
  • the engaging parts of the measuring chamber and main case are Tplreferably formed in the ribs 23 and 24.. e ribs 23 are so spaced as to form with the ribs 24 vertical passages through which the water will flow from the inlet opening 5' and will take its passage up over the measuring chamber and down into the inlet opening ass through this chamber and after operating the disk valve P will pass out the outlet opening 27 and mainoutlet 6.
  • a radial partition 28 separates the inlet and outlet openings in this chamber.
  • a complete circulation through the gear train T is thus formed which prevents the water surrounding the gears from becoming dead" and prevents the settin up of any galvanic'pr electrolytic action terein which ordinarily is the source ofgradual disintegration of the gears. The water itself will not corrode them since they are made of bronze.
  • iston P is peculiar in being made very wi e between striking surfaces, and hence has a wide bearing surface upon the circular walls of the chamber.
  • a ball P is inserted in the opposite edge ofthe disk, which is designed to travel in a vertical groove 29 in the wall of the chamber and hence kee the disk from he body of the disk is also novel in being formedv of materials or a'substance which while being rigid is also not hard enough to produce an great degree 'of friction.
  • This disk is ormed of a composition containing graphite and other refractory materials.
  • the bottom 20 is not attached to the measuring chamber but when attached to the main. case secures the measuring chamber and all the working parts in place.
  • disks for this purpose have been made of vulcanite or hard rubber. but these disks are affected by, heat and warped out of shape. Many materials are suitable for this purpose, but the specific compositiondoes not pertain to the spiritof.
  • the disk piston including the ball and disk is composed largely of a self lubricating non-frictional compound, graphite, which is also refractory in char acter.
  • Other ingredients are india rubber and sulfur, in suflicient quantity to permit vulcanizing the Whole into a solid mass.
  • Other ingredients to give body to the piston may be powdered graphite, or fullers" earth.
