DISK WATER-METER.
SPECIFICATION forming part of Letters Patent No. 527,538, dated October 16, 1894.
Original application filed July 23, 1891, serial No, 400.440. Divided and this application filed November 2, 1893. Serial No.

1 To all whom it may concern:
Be it known that I, LEWIS HALLOOK NASH, a citizen of the United States, residing in South Norwalk, in the county of Fairfield and 5 State of Connecticut, have invented certain new and useful Improvements in Disk Water-Meters, of which the followingis a specification.
.My-present invention consists of certain IO novel parts and combinations of parts specifically pointed out in the claims concluding this specification.
For the purpose of informing those skilled in the art of the nature of my invention I have in the accompanying drawing shown a meter involving the same in the form which is at present preferred by me, which read in connection with the following description will enable persons skilled in the art to make and use the same, but it will be understood that my invention is not limited to the precise form shown andthat various modifications may be adopted without exceeding the scope of the claims. i
l i z 5 The followingis a description of the struct ure illustrated in said drawing.
A B is a meter case preferably made of non-corrosive metal. i 1 l G is a mutating disk arranged for operation e therein.
J is a pin carried by the ball of the disk making connection with an arm carried by a Stud 0, which connects with the registering mechanism of the meter. The piston is com:
posed of metal disk G and metal ball E, the
have claimed the same with other forms go nerically but not specifically.
Among other advantages of. the forms shown the following maybe enumerated: By making the disk of a metal instead of hard rubber, as the disks of commercial meters of this type are now made, I entirely do away with the well known danger of fracture and distortion from various causes. However, if 5 5 both piston and case were made entirely of metal the friction and wear occurring would make the structure of little or no value as a practical water meter. The principal friction surfaces are at the ball of the piston, and its seat in the case and by making these of different materials, the seat being of metal and the contact surface of the ball being of nonmetallic material, the friction and consequent wear are very slight. Thus the maximum 65 strength and minimum wear and friction are obtained and a durable and efficient meter is made. If desired, the parts of the case not in frictional Contact with the piston ball might be made of non-metallic material, although I 7c prefer to make them as described.
In the foregoing specification I have incidentally referred to some of the modifications which may be adopted in the practice of my invention but I havenot endeavored to 7 5 specify them all, and I desire it to be distinctlyj understood that mention by me of some modifications is not in any way intended to exclude others not referred to but which are within the spirit and scope of my invention.
The details illustrated and above described are not essential to the several features of my invention separately considered. This will be indicated in the concluding claims where 8 5 the omission of an element in any given claim or the omission of reference to the detailed features of the elements mentioned is intended to be a formal declaration of the fact that the omitted elements or features are not o essential to theinvention therein covered.
What I claim is- 1. In a water meter, the combination of a nutating pistoncomposed of a ball and disk, both made of metal, the friction surface of the ball being coated with non-metallic ma- 5 terial and a case, that portion of which is in frictional contact with the ball of the piston being made of metal.
2. In a water'meter a nutating piston composed of ball and disk both made of metal, the friction surfaces of the ball being coated to with non-metallic material and the metal surfaces of the disk being exposed.
