' IMPROVEMENT IN LIQUID-METERS.
Specification forming part of Letters Patent No. 127,907, dated J une ll 1372.
To all whom it may concern:
Be it known that I, HIRAM S. MAXIM, of Brooklyn, in the county of Kings and State of New York, have invented an Improvement in Liquid-Meters; and the following is declared to be a correct description of the same.
This meter is provided with double-acting oscillatin g cylinders acting upon cranks placed at about right angles to each other, and in which the pressure of water keeps the cylinders to their seats and makes the valves tight, but allows the parts to yield suciently for any obstruction to Work out from between the valve-face and the seat.
My present invention is to be distinguished from the meters heretofore constructed in which double-acting reciprocating pistons are employed, that act upon ri ght-angled cranks to move a revolving shaft, and slide valves that open and close the ports of the cylinders.
In the drawing, Figure 1 is an elevation of the double-actin g cylinders and section of the case of the meter. Fig. 2 is a view Of the valve-seat. Fig. 3 is a sectional elevation of the cylinder, and Fig. 4 is a sectional plan of the oscillatin g cylinders.Y
The case of the meter is made of the bottom c, cylinder or sides b, and top c. These may be of any suitable material and connected together by bolts d, or otherwise. The inletpipe c is provided with a deilecting cap that directs the'water downward as it enters the casing, so that sand and foreign particles will be deposited upon the bottom. This sediment may be drawn Off by a cock. In the central portion of the case is a vertical standard, h, having on the sides the valve-seats for the valves of the cylinders k and l that Oscillate upon the centers or trunnions n in the standard h. They may also be supported by bearings and trunnions m m. The pistons p and rods r are of any desired character, and the right-angle cranks .s are upon the shaft t and receive the ends of the piston-rods r. The induction-ports 3 and 4 in the standard 7L open out through the side of the standard, as seen in Fig. 4, so that liquid will pass in freely through said ports and enter the cylinders through the ports thereof, when theopenings coincide, from the-oscillating movement of the cylinders. The eduction-ports 5 and 6 open into the hollow standard h and lead to the eduction-pipe c. It will now be understood that the pressure of the water within the case, acting against the cylinders, will press their valve-faces against thel seats on h with a yielding force that is proportionate to the pressure of the water, and by this means the valves will be kept into contact with the seat; but if there should be any foreign substance between the surfaces it will speedily work or wash out by the action of the water and the oscillating movement. It will be apparent that the oscillatin g movements of the cylinders upon their respective centers or trunnions operate the valves, which valves are composed of the faces of the cylinders that are above and below the centers l or trunnions and rest against the sides of the standard h, the ports being in the respective parts as shown.
The shaft t has upon it a worm or screwthread, giving motion to the wheel 10 and vertical shaft 11, at Vthe upper end of which is the crank-arm 16 that acts upon the crank 12 of the shaft '13, leading to the worm 14 and counting apparatus or index. By this construction the parts will move without binding or friction even when the shafts 11 and 13 are not perfectly in line with each other; and in order to prevent leakage around the shaft 13 a spring, 17, is employed to keep the eye of the crank into contact with' the end' of the tube 18.
In case of any hard substance preventing the movement of the cylinders, the ow of water might beinterrupted. To prevent this I employ the valve w, closed by a spring and opening into the delivery-pipe c, so that an accumulation of pressure will cause this valve to open, instead of the water being entirely stopped from flowing.
I claim as my invention- 1. Two oscillating cylinders sustained upon the vertical standard h, and provided with the induction and eduction ports, substantially'as specied, in combination with the inclosing-case and the delivery-pipe, connected with the standard h, whereby the pressure of Signed by me this 26th` day of February, liquid in the ease keeps the valve-faces of the A. D. 1872. cylinders to their seats, as set forth.
2. The shaft 13, spring 17, and crank 12, in terposed between the separate crank-arm 16 Witnesses: and the index mechanism, as and for the purposes set forth.
