Year: 1877

page_text: LETTERS PATENT to Edward Brasier, of Bastable House, New Cross, in the
County of Kent, Engineer, for the Invention of "NEW OR IMPROVED
MACHINERY OR APPARATUS FOR GAUGING AND INDICATING THE THICKNESS
OF PAPER AND OTHER MATERIALS."
Sealed the 4th January 1878, and dated the 5th July 1877.
PROVISIONAL SPECIFICATION left by the said Edward Brasier at the Office
of the Commissioners of Patents on the 5th July 1877.
EDWARD BRASIER, of Bastable House, New Cross, in the County of Kent,
Engineer. "NEW OR IMPROVED MACHINERY OR APPARATUS FOR GUAGING AND
INDICATING THE THICKNESS OF PAPER AND OTHER MATERIALS."
This Invention relates, first, to new or improved arrangements of machinery or
apparatus for guaging and indicating the thickness of paper as it passes from the
paper-making machine.
The apparatus consists of a pair of rollers of steel or other suitable material, the
ends of which are supported in a metal frame. Upon the bearings of the top roller
a beam is mounted which extends across the machine, and upon the top of said
beam a knife edge is fixed which forms the fulcrum of a lever. Upon the long end
of this lever another knife edge is arranged which also forms the fulcrum of another
lever. A toothed rack is secured to the long end of the last-mentioned lever, which
rack gears into a toothed pinion for actuating the indicator.
The operation of the machine is as follows:-The paper is passed through the
rollers, and is drawn through them by the winding drums, and any variation in the
thickness of the paper causes the top roller to rise imperceptibly, and raises the
beam before mentioned with it.. The beam gives motion to levers which are so
arranged that the indicator is at once acted upon.
The object of this part of my Invention is to prevent extra thick paper from
passing from the paper-making machine without the knowledge of. the makers, or
for the purpose of indicating the thickness of the paper as it is delivered from the
paper-making machine.

page_text: In place of employing two rollers the lower roller may be dispensed with, and a
fixed curved surface substituted therefor.
Machinery or apparatus of this character may be employed for guaging and
indicating the thickness of woven or other fabrics, sheets of metal, or other
materials.
SPECIFICATION In pursua
the said Edward Brasier in the Great Seal Patent Office on the 5th January
1878.
EDWARD BRASIER, of Bastable House, New. Cross, in the County of Kent,
Engineer. "NEW OR IMPROVED MACHINERY OR APPARATUS FOR GAUGING AND
INDICATING THE THICKNESS OF PAPER AND OTHER MATERIALS."
This Invention relates, first, to new or improved arrangements of machinery or
apparatus for guaging and indicating the thickness of paper as it passes in
continuous or other sheets from the paper-making machine.
And in order that this part of my Invention may be clearly understood and
readily carried into practice I will proceed to describe the Drawings hereunto
annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a front elevation and Figure 2 is an end view of machinery or
apparatus arranged and applied in accordance with my Invention to the calendering
roller m of a paper-making machine, although I would remark that such or similar
apparatus may be arranged and applied so as to act independently of such roller.
Figure 3 is a separate view on a larger scale of the combined arrangement of
levers and fulcrums employed in carrying out my Invention.
The apparatus consists of a pair of rollers of steel or other suitable material, the
a, a¹; are the frames for carrying
ends of which are supported in a metal frame.
the rollers, and b is a girder piece for strengthening the same, to which is attached
a rigid fulcrum c. d is a beam or girder which extends across the machine, and is
supported upon the journals or bearings of the roller e; and upon the top of said
beam or girder d a block f is fixed, upon which a knife edge rests, which forms the
fulcrum of a lever g. Upon the extreme end of this lever another knife edge h is
fixed or arranged, which also forms the fulcrum or support of another lever i, thẻ
fulcrum of which is at j. A quadrant or toothed rack is secured to the extreme
end of the lever i, which rack gears into a toothed pinion- for actuating the
pointer of the indicator or index 12.
The levers g and i are provided with set screws n and o, and counterbalance
weights p and q for adjusting them.
The Drawings show the guaging and indicating apparatus previously described
as applied to the calendering roller m of a paper-making machine; but it will be
evident to anyone acquainted with this class of inachinery that the apparatus may
be arranged and applied independently of such roller m.
The operation of the machine is as follows:-The paper is passed through between
the rollers, e and m, and is drawn through them by the winding drums, and any

and raises the beam & with it. The beam & gives motion to the levers gand i,
which are so arranged that the pointer of the indicator is at once acted upon.
The object of this part of my Invention is to prevent extra thick paper from
passing from the paper-making machine without the knowledge of the makers, or
for the purpose of indicating the thickness of the paper as it is delivered from the
paper-making machine.
In place of employing 2 rollers the lower roller m may be dispensed with, and a
fixed curved surface substituted therefor.
Machinery or apparatus of this character may be arranged and employed in
accordance with my Invention for guaging and indicating the thickness of woven or
other fabrics, sheets of metal, or other materials; and a competent mechanic, aided.
by the foregoing description and Drawings, will readily arrange and apply apparatus
for carrying out this part of my Invention.
Having thus described the nature of my Invention and the manner of performing
or carrying the same into practice, I would have it understood that I do not intend
to limit my claim to the exact details herein described, as the same may be greatly
varied without departing from the main features and character of my Invention; at
the same time I do not claim separately any of the mechanical parts which are well
known and in common use; but what I claim is,-
The new or improved arrangement of machinery or apparatus for guaging and
indicating the thickness of paper as it passes from the paper-making machine
between rollers or surfaces arranged in combination with a series of compound levers
combined with an indicator, substantially in the manner and for the purpose herein-
before described.
I also claim the arrangement and application of machinery or apparatus, such as
herein-before described, for guaging and indicating the thickness of woven or other
textile fabrics, leather, sheet metal, or other materials within sheets or surfaces,
substantially in the manner herein described.
Lastly. I claim the new or improved method of guaging and indicating the
thickness of paper as it is made and delivered in a continuous sheet from paper-
making machines, substantially as herein described.
In witness whereof, I, the said Edward Brasier, have hereunto set my hand
and seal, this Fourth day of January, in the year of our Lord One thousand
eight hundred and seventy-eight.
