ALEXANDER K. RIDER, OF ELIZABETH CITY, NEW JERSEY.
Letters Patent No. 89,344, dated April-27, 1869. A'
The Schedule referred to in these Letters Patent and making part of the same.
To all whom it ma/y concern y Be it known that I, ALEXANDER K. RIDER, of Elizabeth'Gity, and county of Union, in the State of New Jersey, have invented certain new and useful Improvements in Pumps; and I do hereby declare that the fllwing is a full and exact description thereof.-
My invention relates to the construction ofthe valves, and of the parts and passages adjacent thereto.
I will first describe what I consider the best means of carrying out my invention, and will afterwards designate the points which I believe Ato be new. A
I employ a tube, preferably vulcanized rubber in whole or in part, to serve as each valve, there being four independent valves, and I provide a bonnet at each,` end of Veach valve-chamber, connected together by a bolt, which passes through-the valve-chamber in the space within the interior of the tube which serves as .the valve. V
The valvehas Qsu'icient play to perform properly, whil'efit need not touch the bolt'at all; that is to say, the cavity within the valve is so much greater than the bolt, that the valve may close tightly, and again open to its widest extent, by moving bodily in one directicn or the other, while the bolt stands unaffected in the space in its interior.
The accompanying drawings form a part of this specification. Y
Figure 1 is a longitudinal section, and
Figure 2, a cross-section on line S S, through the entire pump.
Figure 3 is a cross-section through the valve, and its seat and cage on a larger scale.
Figurev 4 is a longitudinal sectionthrough the same, on the inclined line 'I '.l,-in fig. 3.
The remaining iigures show diiierent modiiications in the construction ormaterial of the valve.
Figure 5, a cross-section, all rubber;
Figure 6, a cross-section, all brass;
b Figure?, a cross-section, part brass and part rub- Figure 8, a cross-section, part rubber and part linen; and
Figure, a cross-section, all iron.
Similar letters of reference indicate corresponding parts in .all the figures. 4
A is the cylindricalchamber, which forms the -body of thepump proper, and B is a piston of any approved construction, reciprocated therein by any approved means. It may be operated by steam or other power, may stand in thegperpendicular, horizontal, or variously inclined position, may be made of cast-iron, brass, or other suitable material, may be lined, enamelled, or otherwise prepared, and the piston may be constructed and packed in any approved manner. In' short, the pump, in all thepoints other than those to which my invention directly relates, may be of any approved kind.
Ports or passages, which admit the water into the lbarrel A ofthe pump, and permit its discharge, are
indicated by I I I I.
A cylindrical hole, larger than the Valve, is bored, or otherwise produced, so-,as to form a chamber in the port, extending directly through the casting which forms the body of the pump. -Irito this is fitted a bushing, M, peculiarly constructed, as will be described further on.
The several valves are indicated by N. Each is mounted in a hole in its bushing M, so as to have liberty to play, as above intimated.
The'bonnets G (D2 cover the end of cach valve-chamber and bushing, and are connectedtogether by the bolt D.
' The' four valves, and their respective bushings, may be exactly alike. A minute description' of one will serve for the whole, the only difference necessary being the change of position or inclination.
. 'Ihe valve N may be formed entirely of' ilulanized rubber, or it may serve a tolerable purpose if formed entirely of brass, iron, or various other material, but necessarily in the form of a cylinder. The preferable construction, however, is a tube of India rubber, drawn tightly over a tube of brass, or other suitable metal. i
This construction is indicated in iig. 7, the outer elastic material being indicated by N, and the inner unyielding material being indicated by N2.
The bushing M is hollowed out by coring, or by suitable tools, or partly by each of these processes, so as to form a seat, J, which may be grated or crossbarred, as indicated, to afford a better bearing for the valve when it shuts upon its seat.
The width of the seat corresponds to the width'of the port I, and the metal of the bushing M is solid on each side of the seat. Inother words, when by the force of the water the valve is pressed down upon its seat, it covers tightly the entire communication through the passage, or port I, and forbids the access of water from either side. In other words, it is a tight valve .when shut.
When the force ofthe water lifts the valve, itis allowed, by the form of the chamber m, within the bushing M, to rise from its seat, but the rise gislimited, as represented; that is to say, when it has risen to a sufficient heightto allow the water to iiow freely'around it through passages, now to be described, its further rise is arrested, and it remains in that positiomallowing thewater to flow past it on each side. The, passages for the flow of the water in this manner are indie/ated by mf. These passages are very capacious, and they are divided'simply by slight webs M. 'Ihese'webs may be connected together around the whole exterior of the bushing, excepting immediately against the ports I I; that is to say, the water enters freelyon one side of the hushing, and iiows out freely on the other side.
The remaining surface of the bushing may be either' grated or ribbed, or it may be a continuous shell. VI
' drawings.
It will now be seen that, in the working of the pump,
my several induction and eduction-valves move awav from their seats, and again return to them, bythe action ofthe water. In other words, they are self-acting valves, like ordinary pump-valves, and that they close upon their seats with all the tightness due to a correct adaptation of the forms ofthe parts to each other, and also with the capacity to adapt themselves to inequalities and imperfections due to the India-rubber material on the valve, and that they allow Very long ports measured in the transverse direction across the cylinder, and that they allow very capacious openings, and a very free discharge of the water around them.
The valve is caged by the bushing Very eiectnally, and in case any dcrangement or clogging should possibly occur, or any repairs ever beccme necessary, one
or both the bonnets may be removed by simply taking oii' a nut from the bolt D, and the valve may be immediately drawn o utand examined. The bushings M may be also removed for examination or repairs, if desired.
My invention, as above described, may be applied on pumps, for pumping hot or cold water, air, gases, or any fluid which will not affect the materials.
In cas'e oils, acids, or the like are pumped, which will affect rubber, I make the valve entirely of metal, or of metal covered with leather, felt, orvother suitable soft materialwhich will remain unaffected.
In constructing my pump for pumping air, I esteem it important to place the valve and its bushing as near the main chamber A as is practicable.
The construction of my valve in two concentric tubes,
the exterior of rubber, and the interior of brass, or the ready to move with the least amount of resistance from inertia or other cause.
I can dispense with separate bushing by casting the valve-chambersin one piece with the pump, giving such chambers the same internal form as the bushings described. 4
Having now fully described my invention,
What I claim as new, and desire to secure by Letters Patent, is as follows:
l. The cylindrical valve N, seat J, and cross-bars, or grids M', constructed and arranged as represented, relatively to each other, and to the ports I I of a pump, for the purposes herein set forth.
2. lIhe freely-rolling, or shifting Valve N, having an exterior of soft rubber, and an interior of metal, when made in the form of a hollow cylinder, and mounted to work upon a cylindrical seat, in the manner andfor the purposes herein set forth.
3. The combination of the removable bushing M, formed with `a seat, J and webs M', as represented, the bonnets C* C2, the through-bolt D, and the tubular valve N, constructed, combined, and arranged as represented, for the purposes herein set forth.
In testimony whereof, I have hereunto set my name in the presence of two subscribing witnesses.
A. K. RIDER.
