to be as follows:-
communication
In the manufacture of paper and in the sizing and dressing of warps
as is well known steam is used for the drying of the paper and the
warps, and for the regulation of the pressure within the cylinders em-
ployed as the drying mechanism apparatus known as the steam pressure
regulator has been and is now employed, this regulator being suitably
located between and connected with both the cylinders and the steam
generating apparatus to insure the desired regulation of pressure, that is
to say, to maintain within the drying cylinders a stated amount of pres-
sure, however great may be the pressure of steam within the steam gene-
rating apparatus.
Among the steam pressure regulators employed as above are those
having a valve to regulate the flow of steam to the cylinders wherein it
is to be used, and a diaphragm, on which the steam pressure acts, con-
nected and arranged together so that as the diaphragm is depressed or
lowered because of a reduction in the steam pressure, the valve opens
the passage of steam to the cylinders, and vice versa. In this class of
apparatus a weight is employed to act in conjunction with the diaphragm
of the regulator, to maintain the required steam pressure in the cylinders.
This weight is adapted for adjustment, to act with a greater or lesser force
upon the diaphragm, but after such adjustment it becomes permanent in
its action, that is to say, it acts to all intents and purposes always with
a fixed leverage or weight upon the diaphragm, whatever may be the
increase or decrease of steam pressure, either by generation or con-
sumption, or both; the weight or its leverage being in the one case too
heavy, and in the other too light, to secure a perfect regulation of steam
pressure.
In the use of steam pressure regulators, as aforesaid, it has been found
that while the machinery to which it was connected was running, the
pressure was regulated as desired, but that on arresting or stopping such
machinery there would be in the drying cylinders a pressure greatly in
excess of that to which the regulator was adjusted, in many instances
such pressure being double, thus straining the cylinders, causing leakage
and a liability to explosion. This increase of pressure as stated within the
cylinder is supposed and believed to occur from the fact that there is no
condensation of steam when the machinery is not moving, but on the
contrary an accumulation increasing the pressure, the increase being that

page_text: which during the running of the machinery would be taken up to dry
the paper, warp, or other material. Furthermore, in using simply a
pressure regulator for the purpose stated, the same pressure is given in
all the cylinders, but as some of the cylinders are smaller than the
others it is more advantageous for sizing and dressing warps, drying
paper, and for other like operations, that within such smaller cylinders
the pressure of steam should be below that to which the pressure regu-
lator is set, the several cylinders receiving steam from a common pipe,
that through the pressure regulators used is in connection with the steam
generating apparatus.
The main objects of this Invention are, first, to overcome the stated
disadvantage in the weight or leverage on the diaphragm of the regu-
lator; secondly, to overcome and prevent increase of pressure within the
cylinders when the machinery is stopped; thirdly, in one or more of a
series of the said cylinders to secure a pressure of steam less than that in
the other cylinder or cylinders of the series, the several cylinders of the
series receiving steam through one and the same steam pressure
regulator.
To effect these objects the said Invention consists, first, in apparatus
for producing a leverage or weight upon the diaphragm of the regulator,
which apparatus is so constructed and arranged that in direct proportion
to any increase or decrease of steam pressure the leverage or weight on
the diaphragm will decrease or increase, and thus secure the proper
opening of the valve to maintain the desired steam pressure.
The said Invention consists, secondly, in a connection between a
steam pressure regulator and a paper drying machine, or a slasher, or
other like machine, so arranged and applied to the steam pressure regu-
lator and the said machine that the stopping of the machine will set the
regulator either entirely to arrest the flow of steam to the cylinders, or to
admit less steam to the cylinders than that at which the regulator
is set.
The said Invention consists, thirdly, in the location of a weighted
valve within the passage leading from the common steam supply pipe of
the cylinders (in which supply pipe the pressure regulator is located) to
those cylinders in which it is desiréd to have a reduced steam pressure.
According to the degree in which this valve is weighted or otherwise
adapted to close the passage of steam from the said supply pipe to the

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Robert Lake in the Great Seal Patent
Office on the 3rd December 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Third day of June, in the year of
our Lord One thousand eight hundred and seventy-two, in the thirty-
fifth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said William Robert Lake, Her special license
that I, the said William Robert Lake, my executors, administrators, and
assigns, or such others as I, the said William Robert Lake, my
executors, administrators, and assigns, should at any time agree with,
and no others, from time to time and at all times thereafter during
the term therein expressed, should and lawfully might make, use,
exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for
"IMPROVEMENTS IN STEAM PRESSURE REGULATORS, AND IN THE METHOD OF APPLYING
THEM TO THE DRYING CYLINDERS OF PAPER MACHINES, SLASHERS, AND OTHER LIKE
APPARATUS," a communication to me from abroad by Nathanial Chase
Locke and Alpheus Crosby Locke, both of Salem, Massachusetts, United
States of America, upon the condition (amongst others) that I, the said

page_text: William Robert Lake, my executors or administrators, by an instrument
in writing under my, or their, or one of their hands and seals, should
particularly describe and ascertain the nature of the said Invention,
and in what manner the same was to be performed, and cause the same
to be filed in the Great Seal Patent Office within six calendar months
next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said William Robert Lake, do hereby
declare the nature of the said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained
in and by the following statement, reference being had to the accom-
panying Drawing forming a part of this Specification:-
In the manufacture of paper and in the sizing and dressing of warps, as
is well known, steam is used for the drying of the paper and of the warps,
and for the regulation of the pressure within the cylinders employed as
the drying mechanism apparatus known as the steam pressure regu-
lator has been and is now employed, this regulator being suitably located
between and connected with both the cylinders and the steam generating
apparatus to insure the desired regulation of the pressure, that is to say,
to maintain within the drying cylinders a stated amount of pressure,
however great may be the pressure of steam within the steam generating
apparatus.
Among the steam pressure regulators employed as above are those
having a valve to regulate the flow of steam to the cylinders wherein it
is to be used, and a diaphragm on which the steam pressure acts, con-
nected and arranged together so that as the diaphragm is depressed or
lowered because of a reduction in the steam pressure, the valve opens
more the passage of steam to the cylinders, and vice versa. In this
class of apparatus a weight is employed to act in conjunction with the
diaphragm of the regulator to maintain the required steam pressure in
the cylinders. This weight is adapted for adjustment, to act with a
greater or lesser force upon the diaphragm, but after such adjustment it
becomes permanent in its action, that is, it acted to all intents and pur-
poses always with a fixed leverage or weight upon the diaphragm,
whatever might be the increase or decrease of steam pressure, either by
generation or consumption, or both the weight or its leverage being in
the one case too heavy, and in the other too light to secure a perfect
regulation of steam pressure.

page_text: In the use of steam pressure regulators, as aforesaid, it has been found
that with the machinery to which it is connected is running the pressure
is regulated as desired, but on stopping such machinery there would be
in the drying cylinders a pressure greatly in excess of that to which the
regulator was adjusted, in many instances such pressures being double,
thus straining the cylinders, causing leakage, and a liability to explosion.
This increase of pressure within the cylinders is supposed and believed
to occur from the fact that there is no condensation of steam when the
machinery is not running, but on the contrary, an accumulation increas-
ing the pressure, the increase being that which (were the machinery
running) would be taken up to dry the paper, warp, or other material.
Furthermore, in using simply a pressure regulator for the purpose stated
the same pressure is given in all the cylinders, but as some of the
cylinders are smaller than the others, it is more advantageous for sizing
and dressing warps, drying paper, and the like, that within such smaller
cylinders the pressure of steam should be below that to which the
pressure regulator is set, the several cylinders receiving steam from a
common pipe, that through the pressure regulators used is in connection
with the steam generating apparatus.
The main objects of the said Invention are, first, to overcome the
stated disadvantages in the weight or leverage on the diaphragm of the
regulator; secondly, to overcome and prevent increase of pressure within
the cylinders when the machinery is stopped; third, in one or more of a
series of cylinders to secure a pressure of steam less than that in the
other cylinder or cylinders of the series, the several cylinders of the
series receiving steam through one and the same steam pressure
regulator.
To secure object first the said Invention consists in a leverage or
weight upon the diaphragm of the regulator, which leverage or weight is
so constructed and arranged, or both so constructed and arranged, that
in direct proportion to any increase or decrease of steam pressure the
leverage or weight on the diaphragm will decrease or increase, and thus
secure the desired opening of the valve to maintain the desired steam
pressure.
To secure object second the Invention consists of a connection between
a. steam pressure regulator and a paper drying machine, or a slasher, so
arranged and applied to the steam pressure regulator and the said

page_text: A represents a coupling having four openings B, C, D, and E;
two B, C, in a line at right angles to the two D and E. Within this
coupling, at one side of the passage G through it in a line with
openings D, E, is a wall F separating the passage of coupling between
openings B, C, so that one side of opening C communicates with the
opening D, and its other and opposite side with the opening E, see
Figure 5, Plate 2. Within the coupling chamber G, between openings D
and E, are parallel shoulders a and b, one a at one end of the wall F,
and the other b at the other end thereof, and the two forming continua-
tions of the said wall across the chamber G. These shoulders each have a
similar sized circular opening H through them, which openings H are in
the same axial line as the openings D, E, to coupling A. The shoulders a
and b are the seats for a balanced puppet valve I, which, as shewn, is
placed within coupling chamber G to play in a line from seat a to seat b,
and to come by one of its heads c against the face d of seat a, and by
the other f against the corresponding face g of seat b. The heads c and f
are of equal diameter, which diameter however is larger than the
diameter of the said openings H; they are each bevelled off as shewn
at h to secure a sure, perfect, and steam-tight joint between them and
their seats, and furthermore, the distance between them corresponds to
that between their seats, so that both at the same time will be similarly
and equally closed.
Between the heads c and f the puppet valve is made with longitudinal
radial steam guiding wheels 1, four in number in the present instance,
and under this Invention it is made in two transverse parts K and L,
with one of its heads a or b to each part; the part K is adapted as a
screw bolt, and the part L as a screw nut to be attached to and detached
from each other, the nut part L having arms corresponding to wings 1 of
part K. This construction of the puppet valve I is for the purpose of
securing the location of a puppet valve having heads of equal diameter
or area with a seat for both heads. This hitherto has not been accom-
plished owing to the trouble in locating the valve, for the reason that
with the heads of equal diameter and made permanent and undetachable
the one from the other, as is obvious, it is impossible to pass the valve
either by one end or the other through either one of its seat openings, as
must be done to properly locate the valve within its chamber. Making
the valve however as described, enables the one part to be inserted
irrespectively of the other part, and when these parts are within their

page_text: chamber in their proper relative position to the seats to be secured or
connected together by screwing the one on to the other. In this con-
nection it may be well to remark that to insure the proper location of a
long puppet valve, it is best that its two parts should be of unequal size,
as one part must be passed to its chamber within the coupling A through
the opening B in communication therewith, and not blocked by the
wall F.
The coupling A constructed and provided with a puppet valve as
above described, forms the medium of communication between the steam
boiler and the chamber or cylinder and other parts in which the steam
is to be used, and wherein it is desired to maintain a steam pressure
below the pressure in steam boiler, and therefore for such
it is
purpose
located in a position, such as shewn in the Drawings, and by a pipe at
opening B, connected to steam generator by a pipe at opening C to
chamber etc. in which the steam is to be used, and by a vertical pipe M
at opening E to a steam pressure regulator of suitable construction, the
opening D being closed by a screw stopper or plug N. The steam in
passing from the boiler passes through the chamber G provided the
valve I is opened, both to the chamber in which it is to be used and
to the steam pressure regulator. O is the steam-pressure regulator;
P is the pressure chamber of regulator O with which the pipe M from
coupling A communicates. This chamber P is steam-tight,
end has a flexible diaphragm Q that is secured in any suita
about its edges from displacement, and under this Inventi
through a fixed central vertical stem R with a right angular arm S, both
within the regulator chamber P, it is connected to the lower end of a
vertical stem T to the puppet valve. This valve stem T passes through
the steam conducting pipe M and through stem T; all depressions or
elevations of the diaphragm are communicated direct to the valve I,
proportionately lowering or raising the same. The stem R of the
diaphragm is guided within a socket U at the bottom of the regulator
chamber P.
.:
at one
manner
by and
Outside of the regulator chamber P its diaphragm has a central
vertical stem V passing upward through a stationary guide W. Through
this stem V the diaphragm is loaded to maintain the pressure desired in
the cylinder and other parts wherein the steam is to be used, and under
this Invention this weighting of the diaphragm is accomplished as
follows:-X is a lever passing through the vertical slot m² of the

page_text: diaphragm stem V, and by on end hung to turn on a fulcrum n of
fixed post Y, the other end being free to be weighted to give to said
lever an increased or decreased force; on the diaphragm Z is a clasp
adapted to be moved on the lever X and to be fastened by set screw p.
This clasp Z has a flexible band or chain A' fastened by one end to it,
and by the other to the periphery of a drum or shaft B² hung in
suitable bearings of standards C. The chain A2 by turning the shaft B
is roller up therein or unrolled therefrom as the case may be.
D is a cam or eccentric wheel fixed to shaft B2 herein-before referred
to. From the periphery of this cam wheel D² through a chain E², or a
strap, or line, is suspended a weight F³, or a holder or rest, on which a
weight or weights may be placed. Turning the shaft B the eccentric is
turned, and according to the direction of the turning of the shaft the
flexible strap or chain E is laid upon or allowed to swing off from the
periphery of eccentric. The location of the chain E² on the eccentric
is such that pulling down the chain will pull down the lever X resting
as described on the diaphragm, thus increasing the weight or leverage
therein, and that pulling the strap in the opposite direction the weight
or leverage on diaphragm is loosened.
An arrangement of parts, such as above described, between the lever X
and weight F, first having been properly adjusted to the pressure to be
maintained by applying a weight F³, or a series of weights, or by
changing the position of the slide Z on lever X increasing or decreasing
its length of leverage on diaphragm, or both operates as follows:-
Whether by a decreased generation of steam in the boiler, or by an
increased consumption of steam in the cylinder and other parts wherein
it is to be used, on both, the steam pressure within the cylinder is
reduced; the steam pressure on diaphragm Q to regulator is propor-
tionately reduced, leaving it free to be depressed by the weight or
leverage on it; the arrangement of this weight or leverage on it; the
arrangement of this weight or leverage is such as herein described, that
as the diaphragm lowers or falls it increases in leverage or weight (the
ccentric then turning in a direction to lengthen the arm of leverage of
weight F on the shaft B³, and through it on lever X), and thus it assists
and hastens the depression or fall of the diaphragm, and consequently
the opening of the valve I to the flow of steam through it, establishing
the desired pressure of steam in cylinder, &c.

page_text: And whether by an increased generation of steam in the boiler, or by
a decreased consumption of steam in the cylinder etc. wherein it is to
be used, or both, the steam pressure within the cylinder &c. is increased;
the steam pressure on diaphragm to regulator is proportionately in-
creased, raising or lifting it, as also the lever X, and through it turning
the shaft B2 in a direction to decrease the arm of leverage of weight F³
on said shaft, consequently by thus decreasing its force or leverage
against the diaphragm it will assist and hasten its lifting movement,
and through it the closing of the passage through the valve I for steam,
whereby the flow of steam is proportionately reduced to bring the steam
pressure in the cylinder &c. to the desired amount.
The form of the eccentric or cam D2 is such as at all points of leverage
through it upon the shaft B³, and thus upon the diaphragm Q to cause a
smooth, even, and regular change.
In lieu of suspending the weight F* to a cam periphery, as described,
it may be hung directly to an arm from the shaft, the same effect being
then produced, but not in so smooth and even a manner.
In lieu of an adjustable clasp Z on the lever X I may use a fixed one;
but to have it adjustable is desirable, as it enables a nicer adjustment of
leverage to be made.
As the stem of the valve I is arranged within the steam passage to
regulator no stuffing boxes are necessary, and yet a steam-tight move-
ment of said stem is secured. Also by the arrangement and construction
of the regulator herein described the steam acts on the diaphragm
through a column or body, thus preventing deterioration of the
diaphragm, as is obvious.
In lieu of a flexible suspension of the weight from cam D³, and also
connection between lever X and shaft B3 a rigid one in either one or both
cases may be used, but it is best to have them both flexible, as their
operation and effect are more perfect, steady, reliable, and easy.
In lieu of making the puppet valve in two transverse parts, as
described herein, it may be made in more than two parts; and in lieu of
adapting them to be screwed one on the other, as described, they may be
constructed for being fastened together by independent fastening devices;
and in lieu of the valve being transversely divided it may be longi-
tudinally divided, or both longitudinally and transversely.

page_text: The above arrangement of leverage, in addition to being applied to
the peculiarly constructed and arranged steam pressure regulator herein
described, may be applied to other forms of regulators, and therefore it
is not intended to limit it to any one particular style or construction of
steam pressure regulator, but to apply it to whatsoever steam pressure
regulator it is now or may hereafter be found adapted.
In Figures 1, 2, and 4 is shewn an arrangement of parts for securing the
second object of these improvements that is to overcome and to prevent
increase of pressure within the cylinder, etc., when the machinery is
stopped. This arrangement of parts consists in an arm G* at one end
secured by a set screw to a rod H³, and at the other end connected
through a chain or flexible band I to the axis or shaft B³. The
rod H is the shipper rod that is the rod by and through sliding or
moving which to the right or left the machinery is stopped or allowed
to run.
Under the present connection of the shipper rod with the axis or
shaft B it is intended that the movement of the rod to the right, that
is in the direction of the arrow, Figure 2, shall stop the machinery,
and that the movement of the rod in the opposite direction, that is to
the left, shall allow the machinery to run or produce the connection of
it with driving power.
Now it is plainly obvious, first, that in the stated movement of the
shipper rod to stop the machinery the axis or shaft B is turned in the
proper direction to decrease or relieve its weight or leverage on the
diaphragm of the regulator; or, in other words, to leave the diaphragm
free for the steam pressure to raise it, thereby allowing the valve I,
according as the parts may be adjusted, to rise and to close entirely, or
more or less in degree, the passage through the valve chamber G for the
steam to the cylinder, &c., the steam itself being the medium or force
acting upon the diaphragm to raise it, and thus close the valve; and,
secondly, that in the reverse or opposite movement of the shipper rod
to establish the connection between the machinery and the driving
power the pressure regulator valve or the weight or leverage on the
diaphragm Q of the pressure regulator is set free for action.
The shipper rod may be connected to the valve direct or through the
diaphragm, so that the movement of the rod in the direction to stop the
machinery or cylinder will positively and directly act to close the
valve I, and vice versa.

page_text: It is not intended to limit this part of the Invention to the connection
of the shipper rod with any one particular part of the regulator for
securing a closing or opening of the valve, substantially as described,
nor to any particular arrangement of connecting parts or devices, nor to
the connection with any one particular steam pressure regulator, nor to
a direct connection between the pressure regulator and shipper rod, for
the object desired may be secured in various other ways; for in lieu of
being connected with the shipper rod the pressure regulator may be
connected with some other part that from the movement of the shipper
rod to arrest or set going the machinery will secure the desired effect in
the pressure regulator, as, for instance, with the running parts of the
machinery. The connection of the regulator with the shipper handle
direct is simple, effecient, and practical.
In Figures 6 and 7 is shewn a weighted valve suitable for securing
the third object of this Invention. The construction of this weighted
valve is substantially similar to weighted valves heretofore used in
connection with steam, its construction forming no part of this
Invention.
L³ is a cylindrical case adapted at each end to be attached to pipes;
M2 is a valve to which N is the stem. The valve is arranged
at the opening or seat Os of the case L³, wherein by its wings it is
guided in its movement, and the stem N2 passes through a cross guide
or head P³ of the case L. This guide or head P' and the interior surface
of case L² are relatively constructed with a screw thread, so that the
head can be set to any point in the length of the case, and thus produce
through the spiral spring Q³ around valve stem N2 a greater or lesser
degree of pressure upon the valve M³ to hold it closed.
In Figure 8 is shewn the application of a weighted valve, such as above
described, the valve being at the lower end of the case L³. Let it be
supposed a steam pressure regulator to be located at R², and that it is
adjusted for a pressure of six pounds in the cylinders S3 and T2, pipes
connecting the regulator and cylinders. Furthermore let it be supposed
that in the smaller cylinder Ts it is required that the steam pressure
should be less, say, three pounds. Through the location of the said
weighted valve in the pipe leading to such cylinder this reduced pressure
in cylinder T is secured by setting the spring of said valve to exert on
it a pressure equal to the difference between the number of pounds
pressure desired in the cylinder and the pounds pressure to which the

page_text: regulator is set, which in this case is three. Thus with three pounds of
spring pressure on valve M³ obviously three pounds of steam pressure
in cylinder secures the perfect balance of the valve, and thus its closure
to the admission of more steam until by the consumption of steam in
the cylinder the pressure is reduced destroying said equilibrium, when
the valve again opening, steam passes in, re-establishing the equilibrium
and closing the valve, and so on.
