LIQUID-'lvl ETER.
SPECIFICATION forming part of Letters Patent V1\`|'o..248,'70, dated January 5, 1904. Application led October 30, 1903. Serial No. 179,202. (No modelli To a/ZZ whom t may concern;
Beit known that we, ALONZO S. DRISKO and REINOLD BERRENBERG, residents of Boston, in the county of Suffolk and State of Massa'- chusetts, have invented certain new and useful Improvements in Liquid-Meters, of which the following, taken in connection with the accompanying drawings, is a specification.
This invention relates to liquid meters; and it consists in certain novel features of construction, arrangement, and combination of parts which will be readily understood by reference to the description of the accompanying drawings and to the claims hereto appended, and in which the invention is clearly pointed out.
Figure l of the drawings is a sectional plan of a meter illustrating the invention with` the cover or upper head removed, the cutting plane of the sectional portions being through the axes of the inlet and discharge passages. Fig. 2 is a section on line AIA on Fig. 1. Fig. 3 is a plan of the piston-wingoperating ring. Fig. 4 is a side elevation of the same. Fig. 5 is asectional side elevation of one of the piston-wings drawn to an enlarged scale. Fig. 6 is -an elevation of the outer edge of the same. Fig. 7 -is a section of the same on line B B on Fig. 5. Fig. 8 is a partial section of the casing on line C C.
In the drawings, i represents the casin g having its lower head integral with the peripheral wall and provided with the hub 2 on its under side, in which is formed a hearing for the lower end of the shaft 3, which-also has a bearingin the upper head 4, which is secured to said casing by suitable bolts 5, as shown. The left side of the casing, as seen in Fig'l, is bored out concentric to the axis of the shaft 3, while thefright side thereof is bored out eccentric to the axis of said shaft, as shown.
The shaft 3 has rmly secured thereon, so as to be revoluble therewith, the piston-wheel 6, comprising a base-plate and a peripheral rim surrounding an annular chamber, the periphery of said piston-wheelv fitting closely to the .inner perirneterof the concentric portion of the wall of said casing, but being eccentric to and removed from Contact with the inner surface ofthe right-hand portion of the peripheral wall of said casing, as shown in Fig. 1. The rim 4of said piston-wheel has cut through it a series of radial slots having parallel sides, in each of which is iitted, so as to be movable radially therein, a piston-wing 7, as shown in Fig. 1.y Within the annular Achamber of the piston-wheel 6 is placed a metal ring 8, having a width in the direction of the length of its axis approximately equal to the height of the rim of said piston-wheel above its base-plate, upon which said ring rests in a position to surround the upwardlyproject-ing central hub of said piston-wheel, but free to be moved laterally in said annular chamber to a limited extent for a purpose which will presently appear.
In a bearing in the head 4 is mounted a short shaft or spindle 9, having a squared upper end and a section just below said squared portion provided with a male screwthread, to which are fitted suitable clamping' and binding nuts l0 and l1, respectively, as a means, in connection with the collar 12 on the under side of 'said 'head 4, for clamping said spindle in a fixed or non-revoluble position in said head. The lower end of said spindle 9 has formed thereon an eccentric 13, upon which is mounted,so as to be revolnble thereon, a roller 14, the periphery of said roller being arranged to bear against the inner perimeterof said ring to press it against the inner ends of two ofthe wings .7 and force them into contact with the inner surface of the eccentric portion of the casing- Wall from the time said wings pass the inletpassage 15 until they have advanced one- .eighth of a'revolution, more or less, beyond said inlet-passage.
discharge-nozzle 16 is formed-on the side of the casing opposite to the inlet-passage 15, and said casing 1 has formed in the inner surface of its peripheral wall contiguous to said discharge-passage a groove or by-path 17, which extends on either side of said discharge-passage for the purpose of permitting a free escape of the liquid behind a wing as soon as said wing passes the end 18 of said by-pass, thereby preventing any choking of the machine by forcing the liquid into a constantly-contracting passage. y
The wings 7 have an outline when seen in ICO side elevation, as shown in Fig.` 7, and may be plain solid plates, as shown in theleft-hand portion of Fig. 1, or they may have their outer edges slotted from top to bottom and said slot have fitted thereto a movable case-engaging bar or plate 19, with springs back of them to press them outward into contact with the inner surface of the peripheral Wall of the casing, all as shown in Figs. 5, 6, and 7 and in the right-hand portion of Fig. l.
By the construction of the casing and the piston-wheel illustrated in Fig. 1 a crescentshaped chamber is formed between said `piston-wheel and casing, into which the piston- Wings are forced and made to contact with the wall of the casing by contact with the periphery of the ring 8 as they are carried by said piston-wheel around the axis of the shaft until said wings reach the center of said crescentshaped chamber and then are gradually moved inward again by the action thereon of the wall of the casing, the position of the ring 8 being such as to present no obstruction to such inward movement.
The rim of the piston-wheel 6 has formed therein a series of perforations 20 to save metal and lighten said wheel, but may be dispensed with, if desired. The ring 8 also has cut through it a series of perforations 21 to permit free passage of liquid to its interior,
as when in operation the whole interior 0f the' casing not occupied by the piston-wheel, its wings, the ring 8, and the eccentric and its truck is filled with the liquid.
The bearing of the shaft?) in the upper head is provided with a packing-box and a suitable gland 22 to prevent leakage around said shaft.
The wear of the piston-wings may be compensated for by the spring-pressed bars 19 when 'used or by the ring 8, acted upon by the adjustable eccentric 13 and the roller 14, carried thereby.
The liquid is admitted to the interior of the casing through the inlet-passage, so as to impinge upon the piston-wings substantially at a right angle to their side surfaces as they are passing said inlet-passage.
This invention may be used as a motor operated by water or steam with good results without change.
The operation of this invention will be readily understood from the foregoing without further explanation here.
We claim- 1. In a liquid-meter, the combination of a casing the two opposite halves of which are bored out to arcs of circles eccentric to each other, and provided with inlet and discharge passages; a shaft mounted in bearings in said casing coinciding with the axis of the bore of one-half of said casing; a piston-wheel mounted on said shaft and having a peripheral rim inclosing an annular chamber, and provided with a series of radial slots cut through said rim,the periphery of said Wheel fitting closely to the inner surface of the peripheral Wall of said casing for approximately one-half of its circumference; a piston-Wing itted to each of said radial slots and movable endwise therein; a metal'ring arranged loosely within the annular chamber of said piston-wheel, but eccentric thereto, with one side of its periphery in contact with a pair of the piston-wings and pressing them into contact with the'inner su rface of the eccentric portion of the casing-wall; a roller mounted on an adjustable eccentric, and bearing upon the inner perimeter of said ring, to hold said ring in contact with said wings; and means for securing said eccentric in afixed or non-revoluble position.
2. In a liquid-meter, the combination of a casing the two opposite halves of the chamber of whichare bored out t0 arcs of circles eccentric to each other, and provided with inlet and discharge passages, and a by-pass contiguous to said discharge-passage; a shaft Ymounted in bearings coinciding with the axis of the bore of one-half of said casing; a pistonwheel mounted on said shaft the rim of which incloses an annular chamber and has cut therethrough a series of radial slots; and a series of piston-wings fitted to and movable radially therein; an adjustable eccentric mounted in a head of said casing; means for clamping said eccentric in the desiredadjusted position; a revoluble roller mounted on said eccentric; a ring located in said annular chamber in position to inclose the central hub of said piston-wheel and said eccentric-mounted roller, and to act by its outer peripheral surface upon said piston-wings to force them into contact with the eccentric portion of the wall of the casing.
In testimony whereof we have signed our name to this specication, in the presence of two subscribing witnesses, on this 28th day of October, A. D. 1903.
