WATER METER.

No. 299,213. Patented May 27, 1884.

BENAIAH FITTS, OF WORCESTER, MASSACHUSETTS, ASSIGNOR TO THE UNION WATER METER COMPANY, OF SAME PLACE.
"WATER ll/l ETER.
SPECIFICATION forming part of Letters Patent No. 299,213, dated May 27, 1884. Application filed August 25, 1881. (Model) To all whom it may concern-.-
Be it known that I, BENAIAH Frrrs, of Worcester, in the county of \Vorcester and State of Massachusetts, have invented certain new and useful Improvements in Water-Meters; and I declare the following to be a description of my said invention sufficiently full, clear, and exact to enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification. 7
This invention has especial reference to that class of meters known as the Worthington Meter, and described in Letters Patent N 0. 13,320, wherein two reciprocating pistons and slide-valves are employed, one piston acting directly to operate the valve governing the flow of water to the other piston, and vice versa. These meters as heretofore construct ed, although quite satisfactory in their general operation, are defective in the arrangement of their ports or valve-passages to and from the cylinders, these being a source of frequent derangement and annoyance, since in practice the passages are liable to become filled or clogged with sediment and dirt, and when so clogged their form and arrangement are such that it is inconvenient and difficult to clear them, requiring in some localities much time, labor, and-trouble to keep the meter in proper run ning condition.
The object of my present invention is to obviate this defect and to provide the meter with ports and passages which will permit free flow of water, while they are not liable to become clogged, and are conveniently accessible when desired. These objects I attain by the mechanism constructed as shown and heroin described.
In the drawings, Figure l is a longitudinal section of a meter, (at the position indicated by line 10 w in Fig. 4,) illustrating the nature of my invention. Fig. 2 is a transverse secof Fig. 1. Fig. cylinder at line Fig. 4 'is a plan view of the tion of the cylinder at line as w 3 is a transverse section of the 3 g of Fig. 1.
valve-seat plate.
In reference, A and A denote the two cylinders, respectively provided with pistons B B, fitted to move back and forth with a reciprocating action.
0 indicates the valve-seat plate, secured to the bottom of the cylinders, and provided with guideways c for the slide-valves D, which are arranged to move over their seats and ports by engagement with the pistons B B, the central portion of which is recessed, leaving shoulders b, which engage the projections d on the valve 1).
E E indicate the passages leading from the valve-ports c c to the cylinder A, and I I indicate the passages leading from the ports 23 i to the other cylinder, A. These several passages are all made straight and direct in the valveseat plate, as shown, and are then carried up into the cylinders in the peculiar manner illustrated-i. e., the two passages E and I being made to take a twisting course and to pass each other within the triangular piece between the cylinders, said passages being separated from each other by a spiral or winding partition, which forms a part of the main dividing-partition between the cylinders. The passages communicate with the enlarged end chambers of the cylinders just beyond the finished piston-bearing surfaces a a, as illustrated. The said passages can be made by properlyadjusted cores when casting the cylinders.
The general action of the pistons and valves, as well as the registering mechanism, (not shown herein,) being substantially the same as in the ordinary meters of this class, need. not be herein more definitely described.
The advantages of my improvements are simplicity in the construction and facility of manufacture, adaptation of passages for giving a free flow of water, and non-liability to become clogged by sediment; also, the convenience of access to the interior of the valve-seat plate for cleaning out said passages.
That I claim as of my invention, and desire to secure by Letters Patent, is
The combination of the cylinders A A, having internal bearing-surfaces, a a, said cylinders being separated below by a triangularshapedspace, the pistons B 13, provided with cated in the triangular space beneath the oylshoulders I) b, the removable valve-seat plate inders, substantially as shown and described. 10 0, having guideways c c and ports a a M, and 1 fitness my hand this 22d day OtAuguSt, the valves D D, provided with projections d, A.
