UNITED STATES PATENT EEicE.
JOHN HARTIN, OF NEW YORK, N. Y..
IMPROVEMENT lN WATER-METERS.
Specification forming part of Letters Patent No. 9,1l, dated May 24, 1853.
.To all whom, t may concern:
Be it known that I, JOHN HARTIN, of New York, in the county and State of New York, have invented certain new and useful Improvementsin a Fluid-Meter; and I do hereby declare that the following is a full, clear, and exact description of the fluid-meter with the improvements, reference being had to the accompanying drawings and the letters of reference thereon, all of which form a part of this specification.
The same letters of reference always designate the same object or part of the meter in all the iigures.
In the drawings, Figure l is a longitudinal vertical section. A is a" cylinder. B is a piston. G is the piston-rod, to which is attached an arm, D, which plays by means of a pin in a slit in a connecting-piece, E, which operates a lever, F, to the top of which is attached a ball, G. H H are two slitted connecting-rods, which operate thrte sliding valves, I l2 I3. K K K are passages for the lluid to enter into the cylinder. L L L L L are passages for the tluid to be discharged from the cylinder. M M arejoints in the connecting-rods H H. N is an index for ascertaining how much fluid is discharged from the cylinder. O is a finger fixed to the piston-rod for marking the index. I is a sliding box for regulating the stroke of the piston and the quantity of tluid in the cylinder. Q is a screw by which the sliding box P is moved. B is a sliding piece to be regulated in conjunction with the sliding box P. S is a screw to set the sliding piece It. T T are two flexible metallic rings placed around the pistou to cause it to move tight inv the cylinder. U U are openings in the piston through which the liuid acts on the metallic rings T T.
Fig. 2 is a sectional end View through the center of the cylinder. A is the cylinder. I is a sliding valve for opening and shutting the passages through which the fluid enters into the cylinder. K is a passage for the iiuid to enter into the cylinder. L is a passage for the discharge of the duid from the cylinder.
Fig. 8 is a perspective view of the piston. T T are two iiexible metallic rings. U U U are openings through which the liuid acts on the metallic rings and forces them outward, thus causing the piston to move tight in the cylinder. Vis a cut through the metallic ring to allow it to expand.
The nature of my invention consistsin providing the cylinder inside with a sliding box or stop, l?, which is adjusted in its position by a screw, Q, by which means I can limit the stroke of the piston by causing it to strike against the said box or stop for the purpose of preventing the pin in the arm D from straining upon the stop R in the slotted arm E after tilting the lever F. The sliding box l? in the cylinder and the sliding piece R in the slotted connecting-piece E have to be regulated proportionally, so-as to have the oscillating ball G, with its lever F, operate the valves properly. I make slits in the two connecting-rods H H, which operate the valves, and make likewise a slit in the connecting-piece E. By the combination of these two slitted connectingrods H H and the slitted connecting-piece E with the oscillating ball G and lever F, I obtain a sudden change of the valves whenever the piston has moved to a certain place in the cylinder. I make the fluid itselt` cause the piston to move tight in the cylinder by means of openings U U U, Fig. 3, on the faces of the piston. These openings run obliquely, U U, Fig. l, toward the inside of metallic rings placed in grooves around the piston. Through the said openings the fluid presses against the inside of the metallic rings (which are cut through in one place, as shown, V, Fig. 3) and causes them to expand and press tight against the cylinder. I place an index, N, Fig. l, near the piston-rod, and a finger or point, O, on the piston-rod, by which means I ascertain how much fluid is drawn ott' from the cylinder.
To enable others skilled in the art to make and use my invention, I shall further describe its construction and operation.
I construct a cylinder, A, with its necessary passages, K K K L L L L L, Fig. l, for the fluid to enter and to be discharged through, and proper places for the valves, as shown in the annexed drawings. Into this cylinder, after it has been accurately bored inside, I tit a piston, B, tightly, allowing it to move freely. Around this piston I put tlexilole metallic rings fitted into grooves nicely. Said rings I cut off in one place, V, Fig. 3, so that they can expand. On the faces of the piston I make oblique openings toward the inside of the metallic rings. The rod of the piston passes through one end of the cylinder. At the other end of the cylinder, inside,1 I place a round box, l?, which is tted closely around a projecting piece and made to slide on it by means of the regulating-screw Q. This box P is to limit the stroke ofthe piston. I place one sliding valve in thepassage over the cylinder, I', Fig. l, and two sliding valves at their proper places in the passages below the cylinder, I2 F. To the upper valve, I', I attach a connecting-rod, H, joined at M, said connectingrod being slitted at the end and connected with a lever, F, by means of a pin on the. lever passing through this slit. Io the two lower valves I attach likewise a connectingrod and connect it with the lever F in the same manner as the upper connecting-rod. To the pistoirrod I lix a short arm, D, and conneet this arm with the lever F by means of a slitted connecting-piece, E, and a pin on the arm D, which pin plays in the slit of the connecting-piece E. At the end of this slit I fit a sliding piece, R, to be operated by a screw, S. The piece R has to be regulated in conjunction with the sliding box P in the cylinder, for the purpose as hereinbefore stated. At the top of the lever F, I place a ball, G. I put an index, N, near the piston-rod and a point, O, on the piston-rod to mark the index.
Now, if the fluid enters through one passage at the top into the cylinder, it will force the piston along in the cylinder and at the same time act against those metallic rings on the piston and force them outward, thus preventing the leakage of the piston. When the piston is moved to a cert-ain place in the cylinder, the piston-rod acts Q by means of the arm D and its pin in the slit of the connecting-piece E) on the lever F, and carries the oscillating ball G over the center, when the weight of the ball G carries the lever F down quickly and as quickly changes the valves. The top valve closes the passage where the fluid just entered one end of the cylinder, and opens the other passage for the fluid to pass into the other end of the cylinder. At the same time that the upper valve changes the two lower valves change also, one valve allowing the fluid which passed into the cylinder at one end to be discharged while the other valve is closed and the fluid is passing into the cylinder at the other end, thus causing the piston to move to and fro in the cylinder.
The slits in the connectingrods H H of the valves are for the purpose of leaving the valves undisturbed until the oscillating ball G is can ried over the center, when it causes the valves to change quickly.
The index N marks the quantity which may be discharged during one stroke of the piston. To ascertain how many cylinders of fluid have been drawn, another index must be attached to the meter.
Having thus fully described my improved iuid-meter, what I claim as my invention, and desire to secure by Letters Patent, is-
The adjustable box or stop P in one end of the cylinder for the piston to strike against, for the purpose of preventing the pin in the arm D from straining upon the stop R in the slotted arm E after the tilting of the lever F, substantially as herein set forth.
JOHN HARTIN.
