I IMPROVEMENT IN WATER-METERS.

Gite Sthtult nfm'et tn in that-fitters smut. ant making pm at it: stain;

Be it known that LELmU SPENCER, of Elizabeth, county of Union, and State of New Jersey, have invented alnew and useful Improvement in Water-Meters, or Meters for Measuring'Liquids; and do hereby declare that the following is a full, clear, and exact description thereof, referenc'e being had to the accompanying drawings,

Figure 2, an external and elevation.

Figure 3, a horizontal section through the cylinders and valve-.chest; and

Figures 4 and 5 transverse and vertical. sections of portions of'my invention.

This invention relates to a water-ureter, in which the case or box containing the operatingparts is so constructed as to form the headsof the cylinders-and render the box itself. water-tight, ivhereby the use of stuflingboxes for the piston-rods and valve-stems used in my foruirlpatepted) invention are dispensed with, and a eonsequentincrease oi: power derived from the force or action of the wateizon the pistons, withother advautnges to be hereinafter explained.

In the draivings, A representsthe box, \r'hose base, 13, rests on u ndforms-thdupper headsetthe cstlinders. 0 isa plate, which'constitutes the lower heads of the cylinders, said plate being bolted to the base, '13,. of the box by bolts zz, firmly securingthe cylinders D D and valve-chest E placed between thesaid box and ate. These cylinders and, valve-chest, instead of being let into the parts B as represented, may have flanges at topand bottom for reception of rubber packing between them-and their heads, or the cylinders y gt'ly g-ph e g g may be cast onthe lower plate C, if preferred, ff' are the pistons; g g, the piston-rods, which siitle freely in 1 guides h 7:, cast on the box A. z z' are rods, which connect the piston-rodstwith the arms of the crank-shaft K,

said shaft being also'supported in bearings k is, cast on the box. I] are the slide-valves within the chest E."-

m m m 'm? are the portsof injection, and discharge through which the water from the supply-pipe'y is zidl'nitted and discharged from the-cylinders through -the pipe 2. n n are the valve stems, and o o eccentrics and rods connecting the valves with the-crankshaft K. On the crank-shaft K is placed a worm-wheel, p, which, with the pinion q and shaft r, (passing through a stuflingbox', 8,) nctuates clock-mechanism placed ontop of the host for recording the quantity of waterpassed through the meter.

, Having discovered, from use .oi' thewater-meter for which I obtaiued a. patenqd'une 12, 1866,,that the stufling-boxes and slotted piston-rods used therein, tended to impede the action or force of the water on the pistons, and the form of box, while lli,00IlSllHifi(lD1liChl stock, was*subject to leakage; these defects prompteda me to design the present invention, which I consider an improvement on the former, inasmuch as the disuse of the stufling-boxes to the piston-rods and valve-stems, as well as substituting connecting-rods between the crank .and piston-rolls, for the slotted heads on the piston-rods, whereby I am enabled to remove much friction and render the pistons more sensitive to the force or action of the water thereon; and, besides this, the box is water- 'tight and more compact; and thus I produce n; superior water-m eterand at much lesscost.

What I claiih as my invention, and desire to secure by Letters Patent, is- Y I Constructing the box containing the operating parts of the meter, sons to form the heads of the cylinders and render the box itself water-tight, sirbstant-ially as and for the purposes herein specified. I Ialso claim the arrangement oi the piston-rods g g, in thei'ree guides h It, in combination with connectingrocls i i, substantially as and for the pin-pose set forth. 5

In testimony whereof, I have hereunto set my signature, this eleventh day of December, A, D'..186T. i v ELIHU SPENCER.
