Application filed December 30. 1903. Serial No. 187,201.

To all whomz't may concern,.-

Be it known that I, JOHN D. WALSH, acitizen of the United States, residing at Lockport, in the county of Niagara and State of New York, have invented certain neit7 and useful Improvements in Meters; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

One important-object of my invention is to provide an eflicient, accurate, and wear-resisting device for measuring and metering liqpids which shall be noiseless in its operation, simple in its construction, and free from jar in operation and which may be readily adjusted to meter the same and varying quantities of liquid matter at the same time and varying quantities at different times.

Another important object is so to construct the dash-pot and the bucket and its rockshaft, suitably positioned upon a supporting member, that these parts (namely, the bucket, dash-pot, and rock-shaft) may be readily removed from the device and be used with any appropriate or preferred form of casing, or, in fact, without a casing, enabling me to manufacture these parts and sell them separately from my casing, the buyer being enabled to position these parts in an appropriate casing to suit himself or to use them without a casing, as desired.

Another important object is to provide a novel and improved form of dash-pot.

Another important object is to provide a dash-pot with means for maintaining the same constantly su pplied with liquid for a purpose hereinafter appearing; and my invention consists of the constructions, combinations, and arrangements of parts herein described, illustrated, and claimed.

1n the accompanying drawings, Figure l is a vertical longitudinal section ofthe casing,

taken along line a: of Fig. 4 and showing in rear elevation 'the interior parts of the device,

one position thereof being shown in dotted lines. Fig. 2 is a transverse vertical section taken along line y g/ of Fig. 4. Fig. 3 is a side elevation of my device, a part of the end casing being removed and showing other parts of thecasing in section; and Fig. 4 is a plan view of the device, the casing and parts of the de- Vice being removed along line 2 z of Fig. 1

are formed downward projections as, adapted to engage the inner walls of the caslng and rest upon the interior ange and hold the cap in place. Similar projections or lugs a4, near the center of the cap, are arranged to center the top of a screen E, hereinafter described.l

The upper portion of the casing A is formed with threaded inlet-openings a5, and the lower portion is formed with similar openings adapted to form outlets therefor, both inlet and outlet pipes being adapted to be connected with supply and discharge pipes, respectively. EX- tending across the interior of the upper, portion of the casing and below the inlet-openings a is the horizontal plate or flange al, which may be formed integral with the walls of the casing. This plate is provided with an opening a8 to receive a nozzle D.

Secured to the front cover a of the casing A, on the innersidc thereof, is a bracket B, extending nearly across the interior of the casing A. Rotating in bearings b b2, respectively, in the bracket B and the cover-plate a is a rock-shaft b3. Secured to the upper surface of the lower part of the bracket B are upward-extending stops b", and below the plane of these stops and the outlet-openings a are my peculiar form of dash-pots b5, desirably provided with perforations L6 through their lower peripheries, both the stops and dash-pots being formed integrally with the bracket or suitably secured thereto. My dash pot or pots are preferably formed with Haring sides L7 and with a cone-shaped under periphery 68. The central portion of the dashpot is desirably solid, as at bg, the sides of this solid portion preferably flaring with a curvature conforming to or paralleling the flare of the sides Zf, the solid portion b, with the sides if, forming chambers 51, preferably independent of each other-that is, non-communicating-and of a size larger than the toes of plungers, hereinafter described.

. The curvature of the sides of the dash-potV chambers is very important with a bucket having a rigid plunger or plungers. If the' plungers were pivoted, the sides of the dashpot chambers could be made straight, as usual; but'With-a preferably rigid plunger, as in my construction, and for a dash-pot chamber of my desired size itis my novel ideato make the sides of the dash-pot chambers am curve, (in parallelism, d-esirably,) so that the plunger-toes may swing clear into the chambers al without wedging tight therein, as would be the case were the sides of the dash-pot chambers straight.

Extending longitudinally of the interior of the casing A is open-ended bucket C, formed with a plurality of compartments c c, separated by a partition c. Secured to the under side of the bucket C is saddle-bracket c2, which is suitably secured to the rock-shaft b3, as by set-screws c3.' Projecting downward from the under side of the saddle-bracket are bosses 0*, into which are tapped screws c5, arranged to cpme into contact alternately with the stops or bumpers Z, carried by the bracket, when the bucket is rocked.

Secured to the under side of the bucket are plungers, each preferably comprising an upper toe or foot 07, a vertically-elongated body portion es, and a lower toe or foot c8 of less area than the chambers b1 in the dash-pots b5 and being arranged to strike alternately therein as the bucket is rocked, thus providing an effective cushioningmeans preventing noise.

Extending through the opening as of the horizontal plate or fiange a7 is a nozzle D, which may be threaded into engagement with the walls of the opening. Formed on the u pper portion of the nozzle are shoulders cl3, adapted to rest upon the plate a7, and projecting upward above the shoulders (l2 are lugs Z3 formed to engage vthe lower end of a screen E. The lower end of this nozzle may be tapered and extended to within a short distance of the top of the bucket.

The screen E is of any suitable material and arranged with its top end e centered around the'projections a* of the cap a and is there held between these projections and the interior iange a'. The lower end of the screen is centered around the projections Z3 of the, nozzle D and rests upon the shoulders cl2' .fore that the same, together with the bracket B, the bucket, and rock-shaft supported by the cover-plate a, may be removed readily from the casing. Consequently these parts may be manufactured and sold separately and connected up t-o any suitable form of casing.

In the operation of my invention liquid is admitted through the inlet-openings passes through the screen En and thence down through the nozzle D into one of the com partments c of the bucket C, as indicated by the arrows in the drawings. The screen E serves to. prevent sediment in the water or liquid from passing through, and such sediment finds its way downward to the fiange a7, where it will be below the plane of the top of nozzle D and out of the current of the liquid passing through the device. W'hen sufficient liquid has passed into the compartment c, as shown in Fig. l by dotted line G, the bucket will be rocked downward by the weight of the water, the shaft will be turned, and the water will run out of the end of the compartment, thence into the bottom cf the casing A, filling the dash-pots through the perforations 1), and when the water reaches the level of the outlet-openings a will be carried off. By having the dash-pots on a lower plane than the outlet-openings liquid is retained'in them, and this is a novel feature of my invention. The lower toes 0S of the plungers being of less area than the dash-pots, the liquid can escape only around the edges of the plungers when they enter the dash-pots at each downward movement of the bucket, forming a liquid cushion. The velocity of the bucket is decreased by this arrangement, the noise avoided which would occur if in the operation of the device the adjusting-screws c5 were allowed to strike the bumpers Z without decreasing the momentum of the bucket. As the empty compartment rises pressure of the water on the upper side of the toes csoperates as a slight brake on the ascending plunger` and the oscillating action of the bucket is thereby rendered somewhat less abrupt, thus tending to avoid jar and strain.

The device may have liquid supplied by gravity, or the same may be pumped into the casing through the openings a".

rlhe quantity of water allowed to How into one of the compartments c is regulated by the adjusting-screw c5. It is obvious that should either of the adjusting-screws be carried farther into the boss c* its corresponding bucket or compartment would travel a relatively increased distance downward, and the liquid in the opposite compartment would thereby be allowed to rise to a higher elevation, and a greater quantity of the liquid would be contained in that compartment. The capacity of the other com p'artment would -remain unchanged unless the other adjusting-screw was changed to project a greater 'or less distance out of the boss. It will thus be seen that the device will operate to meter different quantities at the same time and may be. adjusted to meter varying quantities at different times.

It is important in a device of the character of my invention that exact quantities of water shall be measured at each oscillation of the BEST AVAILABLE COPEl bucket, and to this end positive means insuring such precise measurement must be provided. In experiments leading up to the perfection of my present construction, forming the subject-matter of this application for patent, I rst used a spring plate or sheet in the path of movement of the oscillating bucket, against which the bucket would strike, this spring-plate serving as a stop or abutment limiting the degree of downward movementof the bucket, the same as is shown by patents in the art;- but I found not only would the bucket striking against the spring-plate cause a very great and objectionable degree of noise, but the spring-plate would yield to a certain extent, and thus by reason of such yielding the correct and desired quantity of water could not be measured. In other words, the spring-plate was a yielding stop. abutments or bumpers 6*, in connection with the adj usting-screws c5, form a rigid stop, so that exact quantities of water may be positively measured. A
