Specification of Letters Patent.
Patented @luly a, Tall.
Application filed August 21, 1915. Serial No. 46,710.
To all whom it may concern:
Be it known that T, SAMUEL Lrrrnn'r, a citizen of the United States, and resident of East Cleveland, in the county of Guyahoga and State of Ohio, have invented certain new and useful Improvements in Valves, of which I hereby declare the following to be a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.
The objects of the invention are to provide an improved combined suction and discharge valve for use in an air pump, and in which the gravity operated valves are so arranged that they will make a practically sealed joint upon their seats, but can never become choked or seated in the outlet passages upon the reverse movement of the engine.
The valve of this invention is particularly adapted for use with apparatus for pumping fibrous pulp and such like wherein the usual diificulty of clogging and choking experienced in the prior devices is entirely avoided.
The invention comprises the use in connection with the cylinder having a common inlet and exhaust port, of a 'l' shaped union or casing inclosing the inlet and outlet valves and having central and vertical passages communicating with the said port, and includes valve chambers formed of separable portions in the vertical passage in which the valve seats are constructed, and also means for limiting the vertical movement of the respective valves.
The invention is illustrated in the accompanying drawings, hereinafter more fully described, and specifically "pointed out in the claims.
In the accompanying drawings the figure is a vertical central section of the device.
In the figure, A is a T shaped union or valve casing, one extremity of which is attachable to the cylinder of a pump having a piston A and provided with a common port A for inlet and exhaust. The casing is provided with a central passage l3 and communicating therewith a main vertical passage including communicating transversely of the central passage in a vertical direction in the arms of the "l".
A semi-spherical chamber is formed in each vertical passage C C respectively, by means of the enlarged extremities C and C and detachable capping members E and F passaged at E and F. These In the upper cross arm of the 'l' a valve seat S is formed and the semi-circular chamber in the cap in which the valve plays is provided with circumferential ribs R, R, upon its inner face, against which the valve impinges when rising, and which limit its movement but do not prevent the mixture of the fluid or gas or air with pulp pumped out of the cylinders from passing. The valve seat S is formed with a sharp cutting edge whereby the pounding of the globular valves thereupon cuts and chops up the fibers extending therethrough. The valve is therefore self clearing. It is noted that the ribs R are symmetrically arranged and alined with respect to the valve seats S whereby the globular valves are caused to deliver blows directly to the sharp cutting edges of the valve seats S.
The semi-spherical cap is complementary screw threads arm at 42.
It will be seen that the valve will be free to rise until it makes contact with the curved ribs above and that ample passage will remain between the ribs for water, gas, oil or air, or whatever fluid may be pumped, so that the passage will never become choked.
When the outward pressure is relieved the ball valve will fall by gravity and seat itself firmly upon its seat, thus closing and sealing the outlet opening.
The lower or inlet valve H is also gravity operated and the positions of parts in the lower cross arm which contain the valve seat and stop ribs are reversed relatively to the upper cross arm. The larger portion of the chamber C is formed in the lower arm C of the casing and the seat S is formed on the cap portion. Ribs R of the same character as described above in the roof of the chamber permit free flow of air through the passage D, but prevent the valve from closing the opening.
The ball valves G and H are interchangeable and automatic in action and while makattached by on cap and in perfect seats below, cannot possibly choke the passage above, no matter. how high the speed of the engine or the amount of force with which the valves are thrown against the ribs which limit their vertical movement. The balLvalves are preferably made of bell metal but may be made'of other material if desired, especially with chemical or acid pumps.
- This valve is also capable of use in other varieties of pumps andcan be used as check valves in'any piping system.
This device is of the greatest value for pumping semi-fluid and fibrous substances such as wood or paper pulp, since the valves can never become clogged by the material in the pump. The metal ball valves when fall- 1 ing strike against the sharp edges S, S, of
the valve seats, and in rising strike against the sharp edges of the ribs which stop and atthe same time space the balls away from the walls of the casing.
. This action of thevalves will cut into any fibers in the material and will cut apart the material so that it will readily pass through the vertical passages without clogging whereby the valve will clear itself from obstructions.
Having described the invention what I claim as new and desire to secure by Letters Patent is:
1. In a valve, the combination of a T shaped union or casing provided with a central passage and vertical transverse passages communicating therewith in the central and vertical transverse arms ofv said casing, said arms being provided with valve chambers and each valve chamber having in the lower part thereof a circular sharp edge valve seat and each chamber having in the upper part thereof a plurality of circumferentially spaced checking and alining devices and a globular metallic valve Copies of this patent may be obtained for vertically reciprocal in each chamber and adapted to cooperate with said valve seats and said alining ribs for the purpose designated.
2. In a valve, the combination of a T shaped union or casing provided with a central passage and vertical transverse passages communicating therewith in the central and vertical transverse arms of said casing, said-arms being provided with valve chambers and each val e chamber having in the lower part thereof a circular valve seat and each chamber having in the upper part thereof, a plurality of circumferentially spaced checking and alining devices and a globular metallic valve vertically reciprocal in each chamber and adapted to coiiperate with said valve seats and said alining ribs for the purpose designated.
8. In a valve, the combination of a T shaped union or casing provided with a central passage and vertical transverse passages communicating therewith in the central and vertical transverse arms of said casing, capping members detachably secured to the extremity of each transverse arm, each capping member being provided with a passage in continuation of the transverse passage in its respective transverse arm and having a semi-circular chamber formed in the approximated extremity thereof, a globular valve in each chamber, a circular sharp edged valve seat in the bottom of each chamber, and each chamber having upon the upper side thereof a plurality of circumferential checking and alining ribs preventing the closing of the passage, but permitting the passage of fluid therethrough around the valve when the valve is lifted from its seat, said ribs being symmetrically arranged with reference to the valve seat for the purpose described.
In testimony whereof, I hereunto set my hand this nineteenth day of August, 1915.
