impact/ED Mi-:TER FO-R WATER, GAS, 8@ l' Speeiication'forming part of Letters Patent No.. 33,3218, `dated September 24, 1861i,

To all whom it may concern: Be it known that I, HENRY Q. IIAWLEY, of `the city of Albany, in the county of Albany `andState of New York, have invented certain new and useful Improvements in Met-ers for' `Water, Gas, aud other Fluids; andI do hereby declare that the following is a full, clear, and exact description of the saine, reference being had to the accompanying drawings, forming part of this specification, in which 'Figurel is a central longitudinal vertical section of a water-meter with my'improvements. Fig. 2 is a transverse vertical section of the same through one of vthe valve-boxes.

Similar letters of reference indicate corresponding parts in both figures.

This invention consists in 'a novel-systemof valve-operating mechanism applied to opcrate, as hereinafter explained, in combina-4 tion with a reciprocating piston or diaphragm,

upon whose opposite sides the water or other liuid is caused to :actalternately by the op- -eration of the valves affected by the said mechanism.

To enable others skilled in the art. to make andv use my invention, 'I will iirst describe the' construction and operation of the m-eter represented in the drawings,.and then explain, briefly, some modifications which' may be made.

A is a horizontal cylinder having at its .ends two valve-boxcsfB B to which are fitted the .two inlet-valves C C and outlet-valves D D',

and which contain the principal parts of the valve-operating mechanism, .consisting of two levers E E and two tumblingbars F F and their attached tumbling-weights G G1, the

- said bars being connected by chains 'H'.H

with therod I ofthe piston J, which is'itted to the cylinder A, and upon whose opposite cylinder and arranged in the same box B or B' have their stems c or c and d or d conf fnected with'their respective leverE or E ou opposite sides of its fixed fulcrum a or a', so

- that the same movement of the lever will areconnected with opposite ends of the piston-` rod I by means of the chains H H through the agency of 'which the piston can move the tumblingba-rs Aby pulling them, but not 'by pushing them.

Before explainingthe operation of the me.

ter I will remark that the arrangement -of the valves C C and D D is suchthat the" closed valve at either end of the cylinder in let or outlet is subject tothe pressure of the head of water. The operation will be'best undersiom lhy` referring to Fig. 1, which represents the inlet-valve C and outlet-valve Dopenand the inlet-valve C and outlet-valve D closed,',the4 water entering thefcylinder by the box B', vdriving'the piston to the left, and leavingt-he cylinder by theboxB, the chain Hfalling When the pisf` and the chain H tightening ton in this movement arrives within a. certain distance of the lefthand end of the cylinder,

the left-hand end of the rod I cornes in contact with a protuberance on the tumbling# bar F, and at the same instant the chain H' is drawn tight, and the'conti'nued movement y-oi the piston causes the piston-rod Ito push f the bar F and to pull the bar F" in such a mauner that both at the same time pass vertical positions and are caused to'fall over by their weights G G until the harFcomes incontact with the outer arm of. the lever E-that is to say, the arm farthest from the'cylinderand the bar F comes in contact with-the inner arm -of the lever Etha t is to say, the arm nearest the cylinder-letting thechain H-- slack again. The weights G G' now act against the levers Ewith a tendency to close the valves C D and open C D, but are not heavy enough to counteract the pressure -of the water on the closed valves CD', and

the valves therefore remain undisturbed until as the piston arrives very near the left-hand end of its stroke the left-hand end, of its rod I again comes in contact with the tumblingbar Fand\ the chain H is again straightened, and the least continued movement causes the val'ves C and D tostart from their seats, and

as all the lvalves are then nearly balanced or subject to nearly similar pressures of l water F in that movement, by which means as the piston arrives near the right-hand end ot the cylinder the valves C and D are opened again and C and D are closed.

It will have been observed that in the cxample of my invent-ion represented in the drawings the weights are not used to start the valves, but only to complete the opening and closing after 'they have been started, andl hence they do not require to be very large and their arrangement within the valve-boxesv does not'require the said boxes to be of very large capacity; but the weightsalone, it heavy enough, may be depended upon for operating the valves by the fall of the tumbling-bars from the vertical position.

In the above operation it is desirable in order to prevent the too violent slamming of the valves that the weights G G should be arrested by coming down upon the bottoms of the valve boxes before the valves are quite closed, leaving the valves to be closed by the flow of Water alone. To permit this the weights are so'fitted tothe pins e eg', on which they are suspended from the tumblingLbars F F', that a slight upward and downward movement thereon is provided t'or.

In4 the construgtion ofthe meter care should be taken that the. piston-rod and chains .II Il are respectivelyof the proper length to move the4 two tumbling-levers at the same time, and that the length of the movement of the piston is sufficient at least topermit of length enough in the chains to allow either end of the piston-rod to move beyondwhere the end of its attac-hed tu mbling-.bar when pulled over will fall.

Folding rods may be used instead of chains for connecting the piston-rod with the tumbling-bars and will operate in the same manner.

'In adapting the meter to the measurement of gas I propose tov substitute a diaphragm for the piston and' to substitute sliding valves, either at or arc-formed, for the puppet-valves, and the said valves may be operated upon directly by the tumbling-barswithout the intervention ot' the levers E E'.

The wheel and dial work for counting vand registering the strokes of .the piston may be arranged Within either of the valve-boxes vand made to derive motion in any convenient manner from any suitable part of the y valveoperating mechanism. I

By extending the piston-rod through a .stuffing-box in one of the valve-boxes and making suitable connections the same con-f struct-ion ot' apparatus maybe adapted to make a water-pressure engine.

In meters for measuring water in placesl where the head is suffieientto make it ad` vantageous I propose to protect the puppetvalves from the too violent action Vof 'the water,an'd also to regulate partially its action upon them, by means of boxes or shields covering their backs, the water in such ease bei ng admitted to the valves by openings around or near the upper edge of the said boxes 0r shields.

I do not confine myself to the use of any particularl construction or arrangement otl valves; but, v

What I claim as my invention, and desire to secure by Letters Patent, isy l. Combining the piston or diaphragm of a fluid-meter with weighted levers or tumbling-bars for operating the inlet yand outlet y valve or valves thereof by means of a rod I and chains II Il', applied to operate substantially as herein'speeified.

2. The employment, in a Huid-meter, of a Y vsystem oi.' valve-operating mechanism, in

which weighted levers or tumbling-bars arranged within the meter are first brought by' scribed.
