' WATER- METER.
SPECIFICATION forming part of Letters Patent No. 661,067. dated November 6, 1900.
Application filed June 4,1900.
Serial Ito-19,011- (No modem To all whom, it may concern.-
Be it known that I, LEWIS HALLOCK NASH, a citizen of the United States, and a residentof South Not-walk, in the county of Fair-field and State of Connecticut, have invented a new and Improved VVater-Meter, of which the following is a full, clear, and exact description.
Myinvention relates to an improvement in water-meters of that type shown in my Patents No. 211,769, issued January 28, 1879, and No. 408,507, of August 6, 1889, said type consisting of a cylinder having inwardly-extending projections or teeth forming pockets between them and having ports through the heads opening within the pockets and a piston within the cylinder having peripheral projections or teeth adapted to e'nter the pockets in the cylinder and less in number than said pockets in the cylinder. In meters con structed as shown in-said patents pockets Were form ed in the cylinder-wall between the joint forming or bearing surfaces at the inner ends of its projections'and the port-openings in the heads, in which sand and similar foreign matter might lodge and interfere with the action of the meter. In my present invention it is designed that each tooth of the piston shall engage all the peripheral surfaces of the cylinder lying-between adjacent portopenings in the head in passing from one pocket to the next andthat upon entering the pocket some portion of the piston-tooth shall project beyond the inner edge of the port-opening from one end to the other, so that the entire surface of the heads within the port-openings therein are completely swept over by the piston, and any sediment which may enter the cylinder is afforded no place for lodgment, but is promptly swept into the port-openings and discharged.
My invention comprises the novel features which will be hereinafter particularly pointed out in the claims.
In the figures of drawings accompanying, one form of carrying out my invention is shown, the same being a form now preferred by me. It is, however, to be understood that my invention is not limited in its applica tion to this particular form of meter, but may be applied to any form of meter of the class mentioned, some of these forms being shown in the patents above referred to. I do not therefore ish tolimit my invention to the in which similar characters of reference indicate corresponding partsin both the figures.
Figurel is a sectional plan upon the line 1 1 of Fig. 2, and Fig. 2 is a sectional elevation upon theline 2 2 of Fig. 1 with the upper head removed.
The cylinder A has the usual pockets in its inner periphery, formed by the inwardly-projecting bearing-points D and ports K within these pockets, opening into passages in the heads. The piston B also has the projecting teeth E, which are adapted tov enter these pockets, the annular passages G and G, ports g, and the central chambers H and H. The heads also have the ports G and I, all of said tion of the meter is, in its general features, like that of the device shown in said patents.
In my present invention the inner or end surfaces (1 of the bearing-points D between pockets in the cylinder, which are engaged by the surfaces e upon the ends of the pistonteeth, join the side surfaces 01, which are engaged by the side surfaces 6 of the pistonteeth, and said surfaces (1 extend to the inner edges of theport-openings K. Also the piston-teeth E in their innermost position within the pockets project beyond the inner edges of the port-openings K. The portopenings K extend from one of the bearingpoints D to the other and into recesses formed in the sides of said bearing-points. As a consequence of these features the entire surface of the heads within the lines of the inner edges of the port-openings K and the bearing-surfaces d and d is swept over by the piston, and any sediment or foreign substance which may enter the cylinder with the water is forced into the ports and carried out again. This construction leaves no pockets in the cylinder where such matter may lodge, but its entire interior is swept over at each revolution of the piston.
Having thus fully described my invention, I claim as new and desire to secure by Letters Patent--- 1. A meter of the class described having a -parts being in the main like correspondingparts in the patents mentioned. The operadrawings, forming a part of this specification,
case provided with joint-forming projections undercut or recessed on their sides and ports extending between said projections and entering said recesses, combined with a piston provided with joint-forming projections engaging those of the case.
2. A meter of the class described having the inner surfaces of the cylinder between the port-openings in the inner faces of the heads conforming to the paths of travel of the outer surfaces of teeth or projections upon the piston, the sides of said projections of the cylinder being undercut or recessed outside of the inner edges of said port-openings, and said port-openings extending into said recesses, substantially as described.
3. A water-meter having a cylinder provided with inwardly-extending teeth or projections forming peripheral pockets, the cylinder-heads having port-openings within and extending entirely across the pockets, and a piston having teeth less in number than the pockets in the cylinder and adapted to enter said pockets, the outer ends and that portion of the side surfaces of the teeth of the cylinder lying Within the inner port-line being engaged respectively by the end and side surfaces of the teeth upon the piston in passing from one pocket to the other, and the teeth of the piston in their outer positions overhanging the inner edge of the port, substantially as described.
