Application filed February 28, `1922. Serial No. 540,069.

This invention relates to grinding devices,

and especially'for grinding the oscillatory disc pistons of water meters.

The object is to provideta device of this I character which ymay be readily applied to the upper vportion of the measuring chamber of an ordinary water meter, in which they disc form of piston is employed, the device having means for engagement with the drill chuck of an ordinary drill 'press which may be employed for imparting rotary motion to an attachment which, in turn, causes the disc piston to rotate and to rock in the same manner as when driven by the pressure of d the water in its normal operation as a meter,

the said measuring chamber and piston being adapted to vbe immersed in a pan or other receptacle containing a grinding fluid while being supported on th'e bed pla-te of the drill press, suitable clamps, braces or holding meansbeing employed for holding the non-revolving shell or bearing .portion of the grinder from turning while the operation is in progress;v

A full and complete understanding of the invention may be obtained from a consideration of the following detailed description, taken in connection' with the accompanying drawing forming a part of this specification, it being understood that while the drawing shows a practical form of the invention,the latter is not confined to strict conformity therewith, butmay be changed or modi'ed so long assuch changes or modifications mark no material departure from the salient features of the invention as specifically pointed out in the appended claims.

In water meters most generally fused, an

outer casing comprising `upper and lower sections is employed 1n which are housed, 1n the said lower section, an interior'casing `confining a rotary and oscillating disc piston, .which has suitable connection with registering'mech'anism housed inthe upper section of the outer casing, and so arranged, by means of gearing, as to indicate at any time the quantity of water which has passed through themeter. The lower section of the outer casing has suitable nipples forl connection to a pipe line in order to allow the water to enter at one side and to pass out at the other, and the interior casing locatedfin the lower-section is also provided with inlet and outlet passages so that the disc pistonl may be actuated thereby, the said piston being preventedy from revolving'about its own axis by suitable, vertically disposed walls,

well known manner, and lto cause an upwardly directed pin to impart "rotary motion to a vertical shaft included in` aftrain of ears.

g In the continued use of the meter the'l interior casing, havingv the disc piston located therein, is subjected to the passage quantities of water andfrequently becomes clogged with accumulations of` sediment,

which iirst impedes the operation of the pis# ton and gearingto an extent that'accurate with new members.-

the accumulations, that the but free to rock about a central point in a ",85

of great 1 The abovel briefly described parts of an ordinary water ymeterform no part of the present invention, which lis concerned with means for grinding and renewing the'piston, by removing all accumulations yin the` piston casing. Y It has not been deemed necessary,- in the drawing, to y illustrate the construction of the water meter in detail, northeI ,operation of the same, only the pistonlv casing for r wn,

the; same being shown. The casing, constituting a measuring chamber, comprises a lower section l and an upper section 2, suitably tted and held together, and so shaped -asto permit of therncking movement of a ,thus held from axial rotation while allowed toroclnthe said. ball having an axially disposed pin'7; eiitending upwardly through the .upper ball bearing. The casing is yprovided 'with a water inlet on one sideand al water outlet, on theother side, neither of which are shown, while the upperportion of the pis ,ton casing 1s :provided with an upstanding annular flange 8v provided with threads in its inner4 wall.

The invention comprises a tubular sleeve Lor casing, 9,having one endreduced to-provide an extension y1() which is exteriorly threaded and of a diameter to be screwed intorthe said flange 8V of the piston casing,

the shoulder .thus yformed restingupon the upper edge ofthe flange. The casing 9, at the ,threadedenrh is providedwith a counterbore 11 entendingone-third the length of the saine, and abore 12 ofV reduced width which extends ythe remaining portion of the casing. A shoulderl -13,is provided-at the 'juncf tion of the two bores. Extending from this shoulder to a point near the other or upper r end of the sleeve is alongitudinally disposed groove 1.4L, constituting an oil groove, and at theV upper end of the same the casing is provided withv a transverse borell which is suitably. threadeduior the reception of a screw. 16v forja purpose .to be explained.

Adapted to the bore 12 through the casing 9, is an inner sleeve 17 of a` diameter f te yfreely, slide therein, said sleeve having at its lowerend an outstangling flange V18,

adapted to abut against theinterior shoul-y der 13 otthe casing and to form a thrust bearing for the inner sleeve, andprevent its u pward movement. In line with the screw 16, the innerY sleeve 17 isA provided with a peripheral groove19 which isadapted to receive the 'inner end of the saidA screw at ,any to prevent any downward .movement of the sleeve within the casing y when the' device isl being applied for operalatence 21, circular in tormand adapted to snugly iit the counterbore '11 of the casing 9, and provided at one side with an undercut 1nclined slot H22, v.into vwhich is adapted to loosely fit the upstandiirg` pin 7 ot the piston disc 3.. ritthefupper end the spindle 20vis provided with a reduced 'portionl having one side flattened and adapted to enter the chuck 211- ot an rordinary drill press, or any other suitable part of a machine having means tor turning` the device, the said chuck havingI the usual eet screw 25 for maintaining the connection. The threaded portion ot the spindle 20 extends somewhat above the upper end of the casing 9 and receives a clamping nut 2,6 applied thereto, .with a washer 27 interposed be tween the same and the upper-,end ot the casing, said washer being oi" a diameter to extend over and bear upon the said upper end and to form a thrust bearing in, opposition to the aforesaid flange 18.

In operation. the piston casing 1 is removed trom the water meter and placed within a pan, indicated in dotted 4lines at 28 in Figure 1v of the drawing', while saidA pan is supported on the bed plate oi the drill press directly beneathvthe chuclrv 24;. Any suitable means, such as clampingmember 29 which may be formed of wood and held in clamping relation by a bolt 30 may/f be employed to hold the casing from turning and the pan is filled with any suitable grinding` fluid, such as emery and oil, to a level above the casing members 1 and2, so that the interior, ofthe casingfmay be flooded with the same and subjected to the grinding action thereohwhen the rotation ot the drill press is started after the parts are properly connected.l

In applying` the grinderto the piston cas ing, the screw 16 is tightened against the im ner sleeve 17 to prevent `the latter trom turning in the casing 9, when, by unscrewing the nut 26 suiiiciently,.the spindle 29 may be screwed throughy the sleeve `1,7 to bring; the head 21 near to or projecting below the lower end ofthe extension 10` ot the casing. The inclined pin 7 ort the'pist0n may then be introduced into theundercut slot 22 of said head, and theextension threaded into the upstanding ange 8 ot the piston casing. After the. casing 9 kis seated, the spindle 20` may be screwed upwardly throughthe inner sleeve 17,.,which is held from rotation within the .caxsing9 by ineans -ot the screwy 1G, until all binding action of the pin7 within the slot 22 is: relieved, when the clampnut 2,6 is Y.tightened down against the washer 27, which; binds the spindle 2Owithin the inner. sleeve 17 and the screw `16 is then released, whenthe movable partsarefree to rotateqwithin the casing 9 tolproceed with the grinding. operation.
