page_text: We, WILLIAM CHARLES ROSSNEY, of Hyde Park, Gas Engineer, CHARLES
LIVINGSTON HUNT, of Boston, Printer, and CHARLES ALBERT SHAW, of Boston,
Patent Solicitor, all in the State of Massachusetts, one of the United States. of
America do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement:-
Our invention relates to that class of gas-regulators which are operated
automatically by the pressure of the gas; and it consists in a novel construction
and arrangement of the parts, as hereinafter set forth, by which a more effective
device of this character is produced than is now in ordinary use.
It is well known that in nearly all gas regulators having valves, which are
opened and closed by the pressure of the gas in such a manner as to automatically
control the supply delivered to the burners, much difficulty is experienced from the
valves becoming clogged or stuck by gas tar, or by the carbonaceous deposits from
the gas, while others are so constructed as to be less sensitive and certain in their
operations than is necessary to produce the best results.
Our invention is designed to obviate these and other objections, which are
hereinafter pointed out, and to that end we make use of means which will be
readily understood by all conversant with such matters from the following
explanation:
In the accompanying drawing

the drawings.
A represents the body proper, B the gas-holder, C the cylinder and D the base.
of the regulator these nante haing unforchl

page_text: The body A is cylindrical in form, but may be made in any other suitable shape,
and should be about six inches in diameter and eight in height in a regulator for
use with an induction pipe one inch in diameter.
A cover P (see Figure 1) is secured to the top of the body A, by the screws 23;
but instead of being secured in this manner, it may be provided with an annular
downwardly projecting flange for keeping it in position as shewn in Figure 6 or
it may be secured in any other suitable manner. The cover is preferably. composed
of cast iron.
Projecting horizontally and inwardly from the walls of the body A is an
annular flange z, on which is erected a cylinder C, concentric with said body and
open at either end, the body A, flange z, and cylinder C, being cast integral or in
one piece. When not so formed they are connected by gas-tight joints.
The base D is also cast integral with the body A of which it forms a part; but
it may be made separately, if preferred, and be united to the body proper by screws
or other suitable means, whereby a gas-tight joint is produced and the parts held
in proper position, the body proper A, base D, flange z, cylinder O and cover P
constituting the body of the regulator.
Within the body A and preferably disposed on the base D is a vertically
arranged cylindrical hub or projection G which may be cast integral with said
base; but when not so cast it is united thereto or to the induction pipe E, in such
a manner as to form a gas-tight joint therewith.
An annular reservoir or chamber a, open at its top, is formed in said huh, which
hub is also provided with a vertical opening or passage H, extending centrally
through it from top to bottom.
A downwardly closing cup-valve I has its lower portion disposed in the
chamber a, said valve being provided with a stem 22, which is adjustably jointed
or connected, by the pin K to a main counterbalancing lever M. This lever is
furnished with a movable counterbalance or weight N, and the weight provided
with a screw 40 for securing it in any desired position on said lever.
Projecting inwardly and horizontally from the wall of the body A, above the
hub G, is a bar or fulcrum L, having at its inner end a downwardly projecting
arm 24 provided with a series of holes i. The outer end of said bar is screw-
threaded and passes through a hole in the wall of the body A, being properly
packed and secured in position by the lock-nuts 25 and 26, by which nuts and
screw thread the bar is also rendered adjustable laterally of said body.
The lever M is provided at one of its ends with a series of holes f, and at its
opposite end with a series of holes ; and is pivotted or jointed, by means of a pin
or fulcrum proper b in the arm 24 of the bar L between the weight N, and joint
or pin K; being made vertically adjustable on said arm by the pin b and holes i,
and laterally adjustable thereon by the pin b and holes f.
An auxiliary lever Q having its outer end jointed by the pin w to the wall of
the body A, or to a projection thereon, is arranged horizontally within said body
opposite the bar L, and preferably on the same plane therewith, said lever being
both laterally and vertically adjustable.
The lever Q is provided with a series of holes k and is connected with the
lever M by a short vertically arranged rigid bar or link S, said bar being detachably
and adjustably pivoted or jointed at its lower end to the lever M by the pin 27,
and connected in like manner to the lever Q by the pin 28.
A vertically arranged rod J, having its lower end adjustably jointed or pivoted
to the inner end of the rod Q by the pin 29 is firmly connected, by means of the
lock nuts y; l, with the gas holder B, at or near its centre; said rod being,
preferably; secured in the top of the holder in such a manner as to be readily
adjusted vertically therein; and yet so packed as to form a gas-tight joint
therewith.
The rod is elongated at its upper end and passes loosely through the cover P,
as ahewn at 30, thus permitting the air to enter the chamber above the holder B,
and the long arm of the lever M. to be depressed by pushing said rod down and

page_text: the valve I opened to permit a free flow of gas through the regulator, if at any
time the same should be required, and vice versa.
The induction pipe E opens upwardly through the base D, beneath the hub G,
into the passage H the joint between said pipe and the base, and also between said
pipe and hub being gas-tight. An induction pipe F, opening outwardly through
the body A is disposed below the flange z, the joint between said pipe and the
body being also gastight. The latter pipe may however, lead outwardly through
the base D, if preferred, instead of through the body A as shewn in Figure 6.
An annular chamber m is formed between the cylinder C and walls of the body A,
the top of said chamber being open.
A quantity of some suitable liquid preferably quick-silver or mercury, is placed
in the chamber m for packing the holder B, the lower edge of said holder being
immersed in said liquid when the holder is in use.
The chamber in the hub G; flares or is dish-shaped, its outer walls being
inclined at an angle, preferably, of about 45° thereby making said chamber wider
at the top than it is at the bottom, as shewn in Figure 1. Its outer walls are also
vertically grooved or corrugated, as shewn at y in Figure 4.
The body of the cup valve I is vertically grooved or corrugated, as shewn at
16 in Figures 2 and 3, and its lower edge is serrated or provided with teeth 17, as
best seen in Figure 2.
A quantity of some suitable liquid t, preferably quicksilver or mercury, is placed
in the chamber x of the hub G, to form a liquid seat for the valve I, the lower
ends of the teeth 17 being immersed in the liquid when the gas is passing through
the regulator.
When the regulator is used in a position where it is not perfectly stationary, or
when it is disturbed by the jarring of the building in which it is placed, as, for
instance, in a factory where heavy machinery is running, the liquid t is liable to
be slightly disturbed or caused to flow from one side to the other of the chamber a,
thereby causing the gas to be delivered intermittently to the burners, or the lights
to "flicker."
To prevent the liquid t from circulating in the chamber when the regulator is
jarred or disturbed as described, the corrugations y in the outer walls of said
chamber, and the corrugations 16 in the body of the cup valve I are employed, the
liquid falling into the grooves or corrugations and thereby being prevented from
flowing or circulating as freely as it would were the outer walls of the chamber
and body of the valve plain or smooth.
We do not, however, confine ourselves to using the corrugations y, as they may.
be omitted wholly or in part, if desired as shewn in Figure 6, or, instead of the
corrugations, one or more projections of any suitable form may be disposed on
either wall of the chamber a, for accomplishing the same result. The inner wall
of the chamber may also be corrugated instead of the outer, if preferred, or both
may be corrugated.
Neither do we confine ourselves to corrugating the body of the cup valve I, as
said corrugations may be omitted wholly or in part, if desired; as shewn in
Figure 6; or, instead of the corrugations, one or more projections of any suitable
form may be disposed on the outer or inner side of the valve for performing the
same function.
A. fulcrum bar or standard L, for supporting the lever M, may be erected on the
base D, if desired, as shewn in Figure and used in place of the bar L, shewn in
Figure 1.
The liquid t and the hub G provided with a chamber x for said liquid, constitute
a liquid valve seat for the valve I. The pin w serves as a fulcrum for the lever Q
but any other suitable fulcrum may be employed.
The gas-tar and other carbonaceous deposits from the gas which tend to collect
on the lower edge or teeth 17 of the valve I will be washed or detached from said
valve by the liquid or quicksilver tas the valve rises and falls and be blown by
the inflowing gas against the outer walls of the chamber a, to which they will

page_text: .
adhere and thus be prevented from interfering with the proper working of the
valve. It is somewhat important, therefore, that there should be sufficient space
between the valve and the outer walls of the chamber x at the surface of the
liquid t to prevent the tar and deposits, when once detached from the valve, from
returning and re-adhering to it and hence the outer walls of the chamber x are
flared or inclined as shewn in Figure 1 whereby the requisite space is afforded
around the valve I at the surface of the liquid, and the use of the liquid economized,
a less quantity being required than would be necessary if the chamber was of
uniform width throughout.
We do not however confine ourselves to flaring the walls of the chamber, as they
may be formed vertically, if desired, as shewn in Figure 6 sufficient space being
of course provided between said walls and the valve to permit the same to operate
properly.
The jarring or disturbance of the regulator when in use, as described, is also
liable to cause the cup-valve I, to oscillate or swing slightly on the pin K, and
thereby disturb the even flow of the gas, or cause the lights to flicker.
To obviate this difficulty the parts are so constructed and arranged that the
extreme lower portion of the valve is kept immersed beneath the surface of the
liquid t, when the regulator is in use, and an opening or openings, for the passage
of the gas through the the valve is formed therein above the level of said liquid,
thereby preventing the valve from swinging or oscillating when the regulator is
jarred or disturbed, said opening or openings being adapted to be closed by the
liquid when the valve is sufficiently depressed.
In the valve shewn in Figures 1 and 2 the spaces between the teeth 17 constitute
the openings for the passage of the gas through the valve, the points of said teeth
being immersed in the quicksilver or liquid t, to prevent the valve from swinging
or oscillating, but instead of serrating the valve, or constructing it with teeth, it
may, if preferred, be made with slots or openings 19 for the passage of the gas, as
shewn in Figure 5, its lower edge being immersed in the liquid t, in substantially
the same manner as when the teeth are employed. One or more of the slots 19,
may be used as required and they may also be elongated to open downwardly
through the lower edge of the valve, if desired.
We do not, however, confine ourselves to serrating the lower edge of the valve,
or to providing it with openings for the passage of the gas, as the serrations may
be dispensed with, as shown in Figure 6, the gas passing beneath the extreme
lower edge of the valve in entering the regulator when the openings are omitted;
neither do we confine ourselves when it is serrated to serrating the entire lower
edge of the valve, as one or more A-shaped openings may be formed therein,
although we deem it preferable that its lower edge should be entirely serrated.
Neither do we confine ourselves to making the spaces between the teeth strictly
A-shaped, as this form may be varied without departing entirely from the nature
of our invention; nor to making the teeth 17, V-shaped or pointed, as the form of
the teeth may also be varied, if desired.
We however deem a cup-valve, which is serrated or provided in its lower portion
with one or more A-shaped openings for the passage of the gas, the smaller part
or apex of the opening being uppermost, as shewn in Figures 1 and 2 superior to
one which is provided with one or more openings having parallel or approximately
parallel sides, substantially as shewn in Figure 5 for the reason that the width or
area of the A-shaped opening decreases rapidly from its base to its apex and hence
the valve requires to be but slightly depressed to greatly reduce the volume of the
inflowing gas, and, vice versa; or, in other words, the flow of the gas through an
opening thus A in the valve, when the opening is arranged as described, will be in
inverse ratio to the rise or fall of the valve as the case may be; whereas, when
the opening is of uniform width, the quantity of gas passing through it will
correspond with the distance the valve rises or falls.
The auxiliary lever Q and connecting bar or link S may be dispensed with
and the rod J jointed directly to the lever M, if desired, as shewn in Figure 6.

page_text: We, however, deem it preferable to use them, as they enable the valve to be more
delicately adjusted than is possible when the rod J is connected directly to the
lever M and also prevent the lower end of said rod from being sprung or moved
laterally to such an extent as it is liable to be moved when the lever is not
employed.
It will be obvious, that by moving the bar S towards the fulcrum w of the
lever Qthe distance which the valve I will be raised or lowered by the gas holder B
will be decreased, and that, by moving it in the opposite direction, or towards the
rod J, it will be increased.
The weight or counterbalance N may be placed between the bar S and arm 24,
if desired; or it may be placed on the auxiliary lever Q instead of the lever, M if
preferred. The weight may also be omitted and the lever M so constructed as to
act as a counterbalance to the valve.
The top d, of the valve I is thickened to give it weight, and thus enable the
valve to counterbalance, to a certain extent, the movable parts on the opposite side
of the fulcrum pin b.
In the use of our invention the gas is let into the regulator through the pipe E,
passing thence upwardly through the opening H into the valve I thence down-
wardly through the opening or openings in the lower part of the valve or beneath
the yalve as the case may be, into the chamber x, thence into the body A. the gas
holder B and thence through the pipe F to the burners.
When the gas is passing through the regulator as described, if the pressure is
increased, as, for instance, by shutting off, a portion of the burners, the gas-holder B
will be raised accordingly, thereby drawing up the rod J, elevating the long arms
of the levers Q, M depressing the valve I, and decreasing the volume of gas
delivered to the pipe F or to the burners, in the manner which will be readily
obvious without a more explicit description.
Of course, when the pressure within the regulator is decreased, as, for instance,
by lighting an additional number of burners the gas-holder B, will fall, the long
arms of the levers QM be depressed the valve I raised, and the volume of gas
passing through the regulator increased.
It will be obvious that the valve I being provided with a liquid seat cannot be
clogged, with gas tar, to such an extent as to prevent it from working properly,
for the reason that the tar cannot adhere to the quicksilver t, and should it adhere
to the teeth 17, or lower edge of the valve, and thereby partially close up the
opening or openings through which the gas passes, it would merely decrease the
pressure within the gas holder B, and cause said holder to fall and open the valve
accordingly.
As the inflowing gas is discharged directly into the cup of the valve I, the force
of the gas is utilized in assisting to raise said valve, thereby enabling the parts
with which the valve is connected to be so adjusted as to render the regulator much
more sensitive than it would otherwise be.
Of course it will be understood that the valve is to be so adjusted that it will
open sufficiently to supply the smallest number of burners which inay be used when
the gas is let on, and be closed when all of the lights are turned out.
Instead of the valve I with its liquid seat, as herein before described, we some-
times employ a valve constructed substantially as shewn in Figure 7 which will
answer the purpose very well, more especially with large pipes and gas mains.
In Figure 2 the valve I is hemispherical and suspended to the lever M, said lever
being supported by a.fulcrum L and provided with a movable counterbalance N,
as in Figure 1.
The pipe E is elongated and passes through the base D, its upper end a being
bevelled to form a knife-edge seat for the valve so as to prevent the valve from
sticking to it readily should gas tar be deposited thereon.
The weight N is merely auxiliary in its functions, but it enables the valve to be
balanced or adjusted with much greater nicety than would, perhaps be possible
without it use, and is therefore very convenient.

page_text: The object in making the fulcrum of the lever M adjustable vertically is to
regulate, to a certain extent the vertical movements of the valve I; and the object
in making said fulcrum adjustable laterally is to enable said valve to be properly
counterbalanced. The object of the adjustability of the other parts will also be
obvious.
We do not confine ourselves, to the use of the standard L as a fulcrum for the
lever M, as any suitable fulcrum may be employed; nor to elongating the rod J to
pass through the cover P, as said rod may terminate at the top of the holder B with
which it is connected, and an additional rod be employed above said top if deemed
necessary; nor to making the fulcrum for the lever M adjustable, as the movable
weight N when used, obviates, to a great extent the necessity of such adjustability
nor to weighting the lever M when its fulcrum is made adjustable as the use of an
adjustable fulcrum for said lever renders it possible to dispense with weighting it,
although we deem it preferable to weight the lever and provide it with an
adjustable fulcrum.
