Description
UNITE THOMAS MEIKLE, OF LOUISVILLE, KENTUCKY.
IMPROVEMENT IN VALVES FOR HYDRAULIC ELEVATORS.
Specication forming part of Letters Patent No. 186,863, dated January 30, 1877 application tiled August 7, 1876.
To all whom yit may concern:
Be it known that I, THOMAS MEIKLE, of Louisville, in the county of Jefferson and State ot' Kentucky. have invented a new anduseful Improvement in Valves for Hydraulic Elevators, of which the following is a specifica` tion This invention relates to a system of balanced and graduated valves for a hydraulic elevator, whereby the valves can be easily and certainly operated and closed without shock to the pipes.
In the annexed drawings, making part of this specification, Figure l is a vertical longitudinal section. Fig. 2 is a plan view, partly in section; and Fig. 3 is a transverse section of one of the cylinders.
The same letters are employed in all the figures in the indication of identical parts.
A in the drawingis the pipe communicating with the cylinder, and,through lateral branches A1 A2, with the valve-chamber B, regulating the inlet of water, and O, regulating the discharge. In the interior of each is a circular partition, D, forming an intermediate chamber opening into the ducts A1 A2, and, through opening controlled by valves E and El, communicating, respectively, with the inlet and discharge pipes. The valve-seats D1 and D2 are, respectively, in the top and bottom ol' the partition, and support valves E and E1,which fit on the seats and carry a tubular series of downwardlyprojecting points, E2, with converging spaces between them, through which the water ows in passing under vthe valves, so that as the valves descend, instead of cutting o the water suddenly and with a shock, it is gradually diminished as it passes through the converging spaces. The valves are of the same area, and discharge the water equally above and below, so that they are balanced,
and they have pressure both up and down,with only preponderance to keep them well seated. rlhey are attached to astem, F, passingthrough a stuffing-box, and actuated by levers G, having their fulcrum in the middle, and having a stud-pin on the endrentering a curved slot, H, in the T-frame, which moves 011e way or the other by the rack I and pinion K, the movement being determined by the form of the slot, to give a perfectly easy movement to the valves.
I am aware that valves operating upon the same principle have been employed for faucets and for gasand steam regulators, converging recesses being formed in the periphery of the plug with a view to making a very rapid increase of issue as the valve is opened more and more. It is obvious, however, that such valves are not adapted for the purpose to which mine are applied, where a small valve is designed to issue a considerable amount of water, and in which, therefore, the requisite area of discharge is attainable only by cutting through the valve, so as tol form lingers, between which the water will tlow freely from the center. It is to valves of this modied construction that my application is limited.
What I claim as my invention, and desire to secure by Letters Patent, is-
In combination with the val ves for induction and exit, attached to stems F F, the levers Gr G and slotted reciprocating arms H, for alternately actuating the valves, substantially as set forth.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
THOMAS MEIKLE. Witnesses:
THos. MALONE, JAMES TILLEY.
