IMPROVEMENTS IN THE MANUFACTURE OF MEDICATED PAPER, AND IN APPAratus thereFOR
Year: 1884

page_text: I WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake, & Co, Patent Agents,
Southampton Buildings, in the County of Middlesex do hereby declare the nature
of my invention for "IMPROVEMENTS IN THE MANUFACTURE OF MEDICATED PAPER,
AND IN APPAratus thereFOR " to be as follows:-
This invention relates to the manufacture of medicated paper for surgical or
toilet use, and to apparatus therefor.
Strong paper treated in its finished condition with remedial disinfectants or
anti-optic agents is of great value in surgical practice, answering the purpose
of oiled silk and more expensive dressings. It has for such use the advantage of
cheapness, thus admitting, at a small cost, of change of bandage at every dressing.
Heretofore, in the manufacture of medicated paper, so called, by the admixture
of drugs or remedial agents to the pulp while in the heating engines, there is an
apparent impossibility of using anything that will not unite with water. Con-
sequently many of the most valued remedial agents cannot be used, and of those
that may be used, only the cheapest are available on account of the excessive
amount of water with which the pulp is diluted preparatory to passing to tho
forming machinery; where, in connection with the dryers all water and moisture is
removed, carrying with it nearly all if not all of any ingredients that may have
been added with a view to medicating the paper. Only a trace of anything.
combined can be discovered by chemical analysis.
No attempt has heretofore been made to medicate the finished sheet, probably
because of the seeming impossibility of so doing as the slightest wetting of the
thin paper causes it to contract, and 'in drying it wrinkles and consequently loses
its smooth surfaco.
:
By treating the manufactured sheet with an agent of an unctious or oily nature,
such as vaseline, glycerine, paraffine, or any of the animal or vegetable oils, a vehicle
is provided in which to place, and to transfer on to the finished sheets, the agents
most valued by the medical profession for their soothing antiseptic and disinfectant
properties.
The said invention therefore comprises a medicated paper, treated with an
unctious or oily substance as a vehicle for the remedial disinfectant or antiseptic
agent.
It also comprises a process; and apparatus for use in the manufacture.
To prepare this naver I proceed in the manner hereinafter described.

page_text: The apparatus constructed according to this invention is provided with standards
in which are journalled a drying cylinder, a receiving roll over which the paper to
be treated runs on its passage to the periphery of the drying cylinder, a cylindrical
medicating brush, a cylindrical distributing brush, and a second distributing brush
which acts also as a polishing brush.
A delivery roll, is arranged in such a position that the medicated paper passes
over the same before being wound upon a winding shaft.
A trough for containing the medicating liquid extends from one standard to the
other underneath the bearings of the medicating brush, and a roll provided with
bearings between the medicating brush and the trough is arranged to transfer the
liquid from the said trough to the brush.
A steam pipe passes through the said trough for warming the medicine, and
a second steam pipe admits steam to the interior of the drying cylinder; such pipe
passing through one of the hollow journals of the same. An outlet pipe for the
condensed steam also passes through the hollow journal of the cylinder at the other
end of the machine.
The medicating and first distributing brushes are driven by a belt which passes
over pulleys on the ends of the shafts of the same and on the shaft of the second
distributing roller, and a second belt which serves to drive the winding shaft passes
over a pulley on the main driving shaft and a pulley on the said winding shaft.
The second distributing roller is driven by a belt passing over a pulley on the
end thereof and a pulley on the delivery roll. The trough roll is driven by a belt
passing over pulleys on the ends of the shafts of the said trough roll and the
drying cylinder.
The standards for the bearings of the winding shaft have their bearings on the
shaft of the main driving pulley.
A swinging arm is pivotted on one of the end standards and carries a friction
roller, which serves as a tightening pulley to the first mentioned belt.
Motion is communicated to the machine by means of the belt passing over a
pulley on the main shaft and a pulley on the winding shaft.
The winding shaft acts as a driver to the apparatus, first driving the delivery roll
by frictional contact; which roll, through the belts, drives the brushes. The drying
cylinder is driven by the passage over it of the web of paper coming from the
receiving roll, and by the movement of the cylinder motion is communicated to
the medicine take-up roll by the belt arranged as hereinabove stated.”
The operation of the machine is as follows, that is to say: The web of paper to
be treated with the medicating preparation enters by passing onto the periphery of
the drying cylinder over the receiving roll; it receives immediately the medicating
preparation from the brush, which brush is supplied from the trough by the take
up roll which rotates partly within the trough for such purpose. The paper then
passes to the distributing or equalizing brush to have the preparation more evenly
distributed. It then passes to the second distributing brush which serves also to
polish and finish the paper so treated. The paper, still being kept in close contact
with the heated cylinder, passes onto the delivery roll over which it passes and is
received onto the winding shaft and then rewound into a web.
More brushes may be added to the machine; or one or both of the distributing
brushes may be dispensed with, this depending altogether upon the degree of finish
it is desired to give to the paper treated.

Southampton Buildings, in the County of Middlesex do hereby declare the nature
of my invention for "IMPROVEMENTS IN THE MANUFACTURE OF MEDICATED PAPER

It also comprises a process; and apparatus' for use in the manufacture.
To prepare this paper I proceed in the manner hereinafter described.
In the accompanying drawing
Figure 1 is a front elevation of the apparatus or machine employed in the
manufacture.
Figure 2 is an end elevation thereof.
Figure 3 is a central vertical cross section thereof, taken in the line - of
Figure 1.
a, a are the end standards in which are journalled the drying cylinder b, the
receiving roll cover which the paper to be treated runs on its passage to the
periphery of the drying cylinder, a cylindrical medicating brush d, a cylindrical
distributing brush e, and a second distributing brush f which acts also as a polishing
brush.
g'is the delivery roll, and the winding shaft onto which the medicated paper
is delivered.

page_text: i is the medicine trough extending from one standard to the other underneath
the bearings of the medicating brush d, and j is a trough roll having bearings
between the medicating brush & and the trough i
A steam pipe passes through the trough i for warming the medicine, and
a steam inlet pipo admits steam to the interior of the drying cylinder; such pipe
passing through one of the hollow journals of the revolving cylinder. An outlet
pipe m for the condensed steam, also passes through the hollow journal of the
cylinder at the other end of the machine.
The belt n which drives the brushes d and e, passes over pulleys on the ends of
the shafts of the brushes d, e and f, and the belt o which serves to drive the
winding shaft h, passes over a pulley o' on the main driving shaft and the pulley h¹
on the shaft h.
p is a belt passing over pulleys on the ends of shafts of the roll g and brush f
and driving the latter, and q is a belt for driving the trough roll j, the said belt
passing over pulloys on the ends of the shafts of the said trough roll; and the
drying cylinder b.
The standards for the bearings of the winding shaft h, have their bearings on
the shaft of the main driving pulley.
t is a swinging arm pivotted on one of the end standards and carrying a friction
roller t, which serves as a tightening pulley to the driving belt n.
'
Motion is communicated by means of the belt o passing over the pulley, o from
the shaft of the latter to the winding shaft h. The winding shaft h acts as a
driver to the apparatus, first driving the delivery roll g by frictional contact;
which roll g, through the belts p and n, drives the brushes f, e, d. The drying
cylinder bis driven by the passage over it of the web of paper coming from the
receiving roll c; and by the movement of the cylinder motion is communicated to
the medicine take-up roll j, by the belt q, arranged as hereinabove stated.
The operation of the machine is as follows, that is to say:-The web of paper
to be treated with the medicating preparation enters by passing on to the periphery
of the drying cylinder over the receiving roll c; it receives immediately the
medicating preparation from the brush & which brush is supplied from the trough i
by the take-up roll ; which rotates partly within the trough for such purpose.
The paper then passes to the distributing or equalizing brush e to have the
preparation more evenly distributed. It then passes to the brush f which serves
to polish and finish the paper so treated. The paper, still being kept in close
contact with the heated cylinder, passes onto the delivery roll g; over which it
passes and is received onto the winding shaft h and is then rewound into a web.
More brushes may be added to the machine; or the brush e, or the brush f, may
be omitted in the operation, this depending altogether upon the degree of finish it
is desired to give the paper treated.
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:
First. Medicated paper for surgical or toilet use prepared in a roll or otherwise
substantially as described.
Second. Paper treated with combined agents composed of an unctious or oily
substance and a remedial disinfectant or antiseptic agent, the former serving as
a vehicle to properly retain the latter in the paper during the process of introducing
it, substantially as described.
Third. The method of producing medicated paper by treating the paper with
a medicating preparation while the paper is in a heated state, substantially as
described.
Fourth. The combination of a drying cylinder b, with a brush & for supplying
a medicating preparation to paper running over the periphery of such cylinder
substantially as described.

page_text: Fifth. The combination of a drying cylinder b, with a brush d for supplying
a medicating preparation to paper running over the periphery of such cylinder,
and a distributing brush e, substantially as described.
Sixth. The combination of a drying cylinder b, with a brush d for supplying
a medicating preparation to paper running over the periphery of such cylinder,
and a distributing and polishing brush f, substantially as described.
Seventh. The combination of a drying cylinder b, with a brush & for supplying
a medicating preparation to paper running over the periphery of such cylinder,
and distributing and polishing brushes e, f, substantially as described.
