Raising Water and other Liquids.
I CEDRIC VAUGHAN, General Manager, of the Hodbarrow Mining Company, Millom,
in the County of Cumberland, Civil and Mining Engineer, do hereby declare the nature
of my said Invention for "IMPROVEMENTS IN CLACKS OR VALVES FOR PUMPS, AND
APPLIANCES FOR RAISING WATER AND OTHER LIQUIDS," and in what manner the same
is to be performed, to be particularly described, and ascertained, in and by the following
statement.
My Invention is more particularly applicable to heavy pumps, such as are used in
mining and similar operations, where they are worked at considerable depths and under
great heads of water.
The objects of my Invention are twofold,
First, to provide the means by which a clack or valve, or clacks and valves,
(hereinafter called a valve or valves,) may be constructed and fitted so as to better
withstand the action of water or other liquids charged with sand, grit, or other
substances, than is the case with the ordinary types of such valves at present in use for
heavy pumps.
Secondly, to construct a valve or valves in such a manner that those portions of the
wearing surfaces, (hereinafter called the beats), which require repairing, renewing,
changing, or refitting, from time to time, may be more readily and expeditiously
effected than is possible with valves of this class as at present constructed and fitted.
I attain the object of my Invention in the following manner viz
Instead of forming or fitting the beats on the fixed portion of the valve or clack
called the seat or seating, as is the method usually employed, I apply or fit such beats
to the moveable portion of the valve called the cover; and although my Invention is
applicable to various forms of such valves, it is more particularly applicable to a form
of double beat valve, Patented by Messieurs Harvey and West, in the year 1839, (No.
of Patent 8,103).
As the principle of my Invention is the same in whatever form of such valves it may
be applied, it will be sufficient for the present purpose if I describe my Invention as
applied to the form of valve illustrated in the Specification of Messieurs Harvey and
West's, Patent already referred to.
My Invention will be better understood on reference to the accompanying two sheets
of Drawings, on Sheet 1, of which for the convenience of reference I have reproduced
several figures from the drawings accompanying Messieurs Harvey and Wests,
Specification, and on Sheet 2,1 illustrate corresponding views of such a Valve em-
bodying the modifications and improvements which comprise the essential features of
my present Invention; the same numbers and letters of reference are employed
throughout the several views on both sheets of drawings.
Fig. 1, Is an elevation of the valve and seat, the cover being closed.

page_text: Fig. 2, Is a vertical section of the same shewing the cover or valve raised or lifted
from its seat or seats.
Fig. 3, Is a half plan in section of the seat on the line a, B, the cover being
removed.
Fig. 4, Is a half plan of the cover looking towards the interior or underside of the
same, c, c, is the seat made of cast iron or other metal upon which the cover d, d, works;
the faces e, e, and el, el, are faced or turned true, and when shut fit accurately on to the
beats f, f, and f, ff, is the lower beat and ", is the upper heat, in Fig. 2,
e, e, is the top opening of the valve, and e, e, is the bottom opening of the valve, the
dotted lines with arrows in Fig. 2, represent the direction which the water takes when
the valve is opened.
From the foregoing drawings and description it will be seen that the general form
and action of my improved Valve, (as illustrated on sheet 2) and the material employed
in its construction, may be the same or similar to that described in Messieurs Harvey
and West's Specification (as illustrated on Sheet 1), and with regard to these points of
similarity I lay no claim to novelty; neither do I lay any claim to novelty of the
modification in the position of the ribs or feathers 1,1,1,1, as shewn on the cover of
my improved Valve (in Figs. 1, and 2, Sheet 2 of the accompanying drawings) the
ribs or feathers being so placed at an angle act like the blades of a screw propeller or
turbine and cause the cover to rotate and fall in a different position on the seat of the
Valve, at cach beat or stroke of the pump.
As already stated Messieurs Harvey and Wests Valve has the beats formed or fitted
to the fixed portion of the valve called the seat or seating, whereas by my improved
arrangement, I apply or fit the beats to the moveable portion of the valve called the
cover, and in lieu of introducing the beats into circular grooves, cast, turned or other-
wise formed in the face of the cover, I fit and attach the beats to the cover by means
of a metallic ring or rings with bolts, rivets or other equivalent fastenings as illustrated
in Figs. 1, 2, and 4, of the accompanying sheet of the drawings marked number 2
already referred to in which ff, and f¹ƒ, are the beats, h, h, and h¹, h', being the
metallic ring or rings, and i, i, and,, are the bolts, rivets or other equivalent
fastenings.
1
I employ leather, india rubber or other suitable compressible material in the forma-
tion of the beats herein described so that when the cover is down upon the seat or
seats a water tight joint is formed and by the arrangement herein described, when the
beats require repairing, renewing, changing or refitting from time to time, the operation
can be readily and expeditiously performed, by simply removing the old cover and
substituting for it, a duplicate cover which will always be kept ready for the purpose
with the beats fitted for use, and in this way considerable time may be saved and the
consequent danger and risk which invariably attends the stoppage of pumps in mining
operations may be avoided.
Having now particularly described and ascertained the nature of my Invention and
in what manner the same is to be performed, I declare that what I claim is :
(1.) In heavy pumps such as are used in mining and similar operations; applying or
fitting, those portions of the wearing surfaces of the valves or clacks, called the beats,
which require repairing, renewing, changing or refitting from time to time, to the
moveable portion of the valve or clack, called the cover; substantially as herein
described and illustrated, in Figs. 1, 2, 3 and 4, of the accompanying sheet of drawings
marked number 2.
(2.) Improvements in clacks or valves for pumps and appliances for raising water
and other liquids substantially as herein described and set forth.
