In the accompanying drawings, which show so much of our improved apparatus as is necessary to illustrate our invention, Figure 1 represents a view in elevation, with portions of the casing broken away to Show the [interior; Fig. 2, a section therethrough, on the line a: w of Fig. 1; and Fig. 3, a view in perspective of one of the hinged diaphragms or trip-flanges detached.

A metallic frame or case for inclosing and supporting the operative parts of the mechanism is shown as composed of two parts, AA, in this instance of similar construction and corresponding outline, which are united by bolts or screws, so that they may readily be separated. An annular frame or disk, B, is inclosed between the two parts of the supporting and inclosing frame or casing, (which parts are recessed or cut away to receive the disk,) and is caused to revolve, as will hereinafter he explained, with its edge or periphery moving in a groove-seat, b, formed by corresponding shoulders on the inner sides of the sections A A of the supporting-casing. The disk is supported at its center in the supporting-casing by a huh, I), with which it revolves.

- Within and near the periphery of the revolvin g frame or disk are formed a series of sectoropenings, 0. Metal plates D, constituting trip-flan ges or movable diaphragms, are hinged or pivoted at their backs or outer side at equal distances apart to the outer side of this revolvin g frame, so as to swing or open and close within these openings 0. To keep the plates in proper position and prevent wabbling on their pivots, guide notches or recesses 61 d are formed at their outer or free ends, and at their backs, so that the plates embrace the revolving frame, and are kept in position at right angles thereto. The back notches (I embrace the lugs F, to which the plates are hinged. A water-way or conduit, G, is formed by recessing or cutting away the sections A. A of the frame from the inlet G to the outlet G This conduit is preferably so made as to represent in form, in cross-section, the outline of a truncated cone, with its base outward. A groove or guidewa-y, H, for the movable diaphragms D, leads from the eduction G at the termination of the conduit to the induction G at or near the beginning of the conduit. This groove is formed in the two parts of the frame or case A A, and terminates at its opposite edges or sides, in both parts, flush with the wall of the outer or largest portion of the conduit, and flush. with the inner edge of the groove-seat or rest b, respectively.

The operation is as follows: The liquid enters the induction-pipe G impinges against the hinged diaphragms or trip-flanges, closing or swinging them out across the conduit, formin g movable compartments therein. When the diaphragms reach the terminus of the conduit (where they are carried by the current) they abut against a stop, I, formed bya shoulder crossing the conduit from the guideway or groom H to its opposite Side, and forming an abutment terminating the conduit. This folds the diaphragm back against the outer wall of the guide-groove, into which they pass, and in which they fit snugly, to prevent leakage from the conduit, the liquid passing out at G and the diaphragms, as their disk revolves, being carried around in the groove, (the fluid in the meantime acting on the succeedin g diaphragms,) and again, in succession, being presented to the current of liquid, and

As the area in cross-section of the inlet and of the outlet'are each the same as that of the conduit, there'is' no dead liquid accumulated during the Operation.

The' peculiar form of the conduit is advantageous, as the largest portion of the body'of the liquid, an d consequently the greatest pressure, is exerted against the backs of the diaphragm's, thus acting on the disk with greater leverage than'could be brought to bear'were the diaphragms of uniform sectional area throughout their entire length. The liquid as it enters the conduit is deflected froni'its nar row to its wider side. 7 r r The area of the 'diaphragms being slightly larger than that of the conduit,the pressure 7 always causes them to fit snugly, notwithstanding the wearing away of the diaphragms, Another advantage due to our method of hin'ging the diaphragms at their .outer ends instead of their inner ends,'as heretofore practiced, is that thediaphragm is drawn across the face of the induction-pipe some distance 7 before opening, so as to allow the eompart' ment in advance of it to be completely filled, and then opens quickly but steadily when released from its guiiling-groove, owing to the pressure of the liquid behind, and thus avoids the slamming of the diaphragms. The stop at the educt-ion end of the conduit gradually disk, and thus swings out the diaphragm in the direction of the outflowing current, thuspressing out the liquid, and the diaphragms fit so snugly in the grooveH that flooding iseffectnallypre- V vented'that is to say, there can be no dead 7 7 space in this meter, and'consequentlyit must 1 7 always registeruniformlyand accurately 'Wedo not, broadly, claim actuating hinged diaphragms by the pressure of a column of liquid fiowing'through a'conduit,as we find that this is old; but
