To all whom it may concern:' Be it known that I, FREEMAN W. H001), a-

citizen of the United States, vresidin g at NeW-* ton, in the county of Middlesex andCommonwealth'of Massachusetts, have invented a new and useful Improvement in Water-Me;

. ters, of which the following is a full, clear,-

and exact description, reference being" h'adto where it passes by the inlet-port c, which port is shown by the dotted line back of the abutment (it.v The natural trend of the piston,due to the direction of the current of the water, and

which is the same as the direction of the gymtion of the piston, in, ordinary constructions is against the side of the abutment nearest the outlet-port, at whichpoint the thrust is received by the slotted edge of the piston. In order to relieve this thrust and obviate the" friction incident thereto, I have widened the face of the abutment back to the point marked f, that is, that face which is adjacent to the a ball of thepiston, indicated by e, and have.

f so that the pin g, which I insert loosely and slotted it perpendicular to the'bottom plate,

radiallyin the ball of the piston, may vibrate freely therein as the piston gyrates. In this way l aln enabled to out a wide slotiinthe piston, so wide in fact that the slotted edge I does not bear at any point on the abutment,

ll-the thrust of the piston being taken up by the pin gin the slot h. On account of the pin- 9 being fitted loosely in the ball, it makes a perfect roller-contact in the slot h and a rotating contact in the ball of the piston. The effect of this-arrangement is to ento greatlyred uce the friction, and consequently improve the registration and increase the sensitiveness and durability of the meter. To still further decrease the thrust due to currents of waterat high velocity, I have beveledthe edge of the piston at b, where it passes the-port a, so that the water will not :face, as in the ordinary construction, but ineither side of'the piston.

Having thus fully described myinvention, what I. desire to claim and secure by Letters Patent i s with a disk-chamber and disk, of an abutment provided with a slot in the face thereof adjoining the ball of the piston, a pin projecting from the ball of said piston and acting in said slot, substantially as set forth and described.

In a disk water-meter adisk, a pin, projectin g radially from the center of the ball of the disk, said pin acting in a slot in the face disk, substantially as set forth and described.

3. In adisk. water-meter a disk,a pinprojecting from the ball of the disk, said pin being free to rotate in the ball of the disk and roll against the side of a slot in the abutment, substantially as set forth and described;
