Improved Means for Indicating Stoppage of the Outflow of the Stuff
Tap in Paper Making Machinery and for analogous Uses.
I, GEORGE EDWARD JORDAN, of Oswald Place, Dover, Kent, Papermaker, do
hereby declare the nature of this invention to be as follows:-
This invention relates to improved means which are particularly applicable
for automatically indicating stoppage of the outflow of the stuff tap in paper
making machinery, but are also applicable for analogous use in other apparatus
liable to become blocked by the passage of semi-liquid matters flowing there-
through or therefrom.
To this end, the invention is characterized by the application to the paper
making (or other) machinery of an electrical indicating device in combination
with a device by which the electric circuit is kept unclosed during the proper
flow of the paper stuff, and is closed on the cessation of such flow; the flow
of the stuff being thus instrumental in detaining such device out of operative
position, and the device being automatically operative in completing the electrical
circuit upon the flow of the stuff ceasing to detain it.
In applying the device, say, to a paper making machine, 1 locate it in the
shoot leading from the stuff chest to the wet end of the paper making machine,
opposite the outlet from the stuff chest into said shoot. The device consists of
a plate located opposite said outlet and supported by a lever which is pivotally
mounted on the shoot sides and is formed or provided with a counter-weighted
arm constantly tending to hold the said plate towards the paper stuff outlet and
also to close an electrical alarm circuit. The arm carries a contact plate elec-
trically connected to an alarm bell in circuit with one pole of a cell or battery,
the other pole of which is connected to a contact plate with which that of the
said arm is adapted to make contact when the paper stuff outlet is blocked and
the stuff ceases to flow. When the paper stuff is properly flowing its impact
against the opposite plate so acts thereon as to keep the contact plate of its
arm out of contact with the contact plate in direct electrical connection with
the cell or battery, and, consequently, an alarm is only given when the paper
stuff ceases to properly flow.
The plate arm being counterweighted as aforesaid can be adjusted to accom-
modate any required pressure or supply of the feed so that when the paper stuff
either ceases to flow through the outlet or stuff tap or partly ceases so that
ts pressure on the plate is less than the counter-pressure of the counterweight,
he lever will swing on its bearings and the alarm will be sounded, so drawing
he attention of the machine attendant to the necessity of clearing the paper
tuff outlet in order to prevent the formation of broken and thin paper which
would otherwise be liable to be made.

Tap in Paper Making Machinery and for analogous Uses.
I, GEORGE EDWARD JORDAN, of Oswald Place, Dover, Kent, Papermaker, 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:-
This invention relates to the application to paper making machinery and to
other apparatus liable to become blocked by the passage of semi-liquid matters
flowing therethrough or therefrom of the hereinafter described means of auto-
matically indicating the stoppage or lessening of the outflow of the stuff tap
or other outlet in such machinery.
To this end, the invention is characterized by the application to the paper
making or other machinery of an electrical indicating device in combination
with a device by which the electric circuit is kept unclosed during the proper
or desired flow of the paper stuff and which is automatically closed upon the
cessation or lessening of such flow, the flow of the paper stuff or other semi-
liquid matter being thus instrumental in detaining such device out of operative
position, and the device being automatically operative in completing the
electrical circuit upon the flow of the stuff ceasing to detain it.
The accompanying drawings represent, by way of example, the application of
the device to a paper making machine, showing it as focated in the shoot
leading from the stuff chest to the wet end of the paper making machine,
opposite the outlet from the stuff chest into said shoot; Figure, 1, representing
a side elevation; and Fig. 2, representing a sectional front elevation with the
electrical apparatus represented diagrammatically.
The device consists of a plate, a, located opposite said outlet, b, and supported
by a lever, c, which is pivotally mounted, at i, on the sides of the said shoot, d,
and is formed or provided with an arm, e, having an adjustable counterweight, f,
constantly tending, when the apparatus is in action, to hold the plate, a, towards
the paper stuff outlet, b, and also to close an electrical alarm circuit, g, h, i, j,
k, l, m. To this end, the arm, c, carries an adjustable contact plate, m, electrically
connected to an alarm bell, k, in circuit with one pole of à cell or battery, i,
the other pole of which is connected to a contact plate, g, with which that of
the said arm is adapted automatically to make contact when the paper stuff
outlet is blocked and the stuff ceases to flow therethrough. When the paper
stuff, o, is properly flowing its impact against the opposite plate, a, so acts
thereon as to keep the contact plate, m, of its arm, c, out of contact with the
contact plate, g, in direct electrical connection with the cell or battery, i, and,
consequently, an alarm is only given when the paper stuff ceases to properly flow,
when the plates, g, m, make contact and complete the electrical circuit.
The plate arm, e, being adjustably counterweighted as aforesaid, can be
adjusted to accommodate any required pressure or supply of the feed so that,
the contact plate, m, being correspondingly adjusted, when the paper stuff
either ceases to flow through the outlet or stuff tap or partly ceases so that its
pressure on the plate, a, is less than the counter-pressure of the counterweight, f,
the lever will swing on its bearings and the alarm will be sounded, so drawing
the attention of the machine attendant to the necessity of clearing the paper
stuff outlet in order to prevent the formation of broken and thin paper which
would otherwise be liable to be made.
The adjustability of the counterweight also permits, when the apparatus is
not in action, of its being so set adjacent to the fulcrum of the lever that the

page_text: be so neid or will so hang that the contact plates, g, m, will not make
contact and the alarm will consequently not be sounded.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
-
and
or
;
The application to paper making machinery
become blocked by the passage of semi-liquid matters flowing therethrough or
other apparatus liable to
herefrom of means of the nature hereinbefore described for automatically indi-
ating the stoppage or lessening of the outflow of the stuff tap or other semi-
iquid outlet of such machinery.
