PROVISIONAL SPECIFICATION.
An Improved Plaister for Medicinal Purposes.
I, JOSEPH HENRY OSGOOD, of Peabody, in the County of Essex, and State of
Massachusetts, United States of America, Manufacturer, do hereby declare the
nature of this invention to be as follows:—
My invention relates to plaisters for medicinal purposes and it has for its several
objects
(1) The preventing of the plaister adhering directly to the person, except only
at its ends (or sides) or at such parts as may be convenient to the wearer, leaving
the rest of the plaister, that is, its effective or active part free to adapt itself to the
motions of the body in any and every direction without impairing the 'efficiency of
its medicinal action;
(2) The covering of the plaister, that is, the part which is not intended to adhere
to the flesh, with a layer of medicated or non-medicated cotton, wool or equivalent
fibre, such material, whether medicated or not, clinging at its under surface directly
to the adhesive material of the plaister and serving to give warmth and protection
to the skin, and to produce a gentle, pleasant friction due to the movements of the
body, inasmuch as the plaister does not adhere to the person anywhere except at its
edges or sides or other limited portions as may be predetermined;
(3) The furnishing of a light, easy comfortable plaister, which (unlike most
plaisters of any considerable size, and which cling to the skin by their entire or nearly
entire surface) will not painfully contract the skin or be difficult to remove;
(4) The availing of all the advantages due to perforations (if perforations be
availed of) but in a novel and better manner than usual and without weakening the
structure of the plaister;
(5) The opportunity of medicating at will the above named fleecy material, and
this independently of any medication of the adhesive material; and
(6) A means for lessening at the sticking parts of the plaister the force of the
adhesiveness to the skin, while at the same time permitting enough of the sticking
quality to hold the plaister to its place without the need of any strings or band.
The plaister may be made in any desired shape or form.
In carrying out my invention I employ a textile backing piece, on the front face
of which is placed the.medicated material and the whole may, if desirel, be
perforated with numerous holes made either through the cloth or through the fleecy
material hereinafter mentioned, or through both. Cotton, wool or kindred fibre or
fleece is laid over and clings to all the surface of the material, except at those
parts which are to adhere to the person.
It will be seen that my improved plaister is always ready and in a permanent and
portable form for immediate use, and may be made of any desired size or shape and
that the fleecy material may at any time be medicated with any desired medicament;
that it is easily applied to any desired part of the person that it adheres to the
skin only at certain portions and such only as are enough to hold it in place; that
the cotton or equivalent material not only holds its own place without sticking, but
also interposes between such non-medicated sticking material and the flesh,
permitting of free movements of the body. It also gives all the benefit derivable
from the warming properties of the fibre, and allows the medication of such fibre,
if desired.
Another advantage is that the plaister can be folded up flat without injury, and
shipped in quantities or mailed in a letter, the non-adhesive cotton of fibre
preventing the folded faces from sticking together; hence it can be readily opened
or unfolded when wanted for use, and this folding tends to preserve and retain the

page_text: healing qualities of any medicaments which may have been previously applied to
the fleece.
With my invention the sticking portion of the plaister merely serves to confine
the plaister to the body or keep it in close contact therewith, while the fleecy layer
of cotton, &c., when properly medicated, furnishes the active medicinal principles
which tend to effect the cure.

COMPLETE SPECIFICATION.
An Improved Plaister for Medicinal Purposes.
I, JOSEPH HENRY OSGOOD, of Peabody, in the County of Essex, and State of
Massachusetts, United States of America, Manufacturer, 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:-
My invention relates to plaisters for medicinal purposes, and it has for its several
objects:
(1) The preventing of the plaister adhering directly to the person, except only
at its ends (or sides), or at such parts as may be convenient to the wearer, leaving
the rest of the plaister, that is, its effective or active part free to adapt itself to the
motions of the body in any and every direction without impairing the efficiency of
its medicinal action :
(2) The covering of the plaister, that is, the part which is not intended to adhere
to the flesh, with a layer of medicated or non-medicated cotton wool or equivalent
fibre, such material, whether medicated or not, clinging at its under surface directly
to the adhesive material of the plaister and serving to give warmth and protection
to the skin, and to produce a gentle, pleasant friction due to the movements of the
body, inasmuch as the plaister does not adhere to the person anywhere except at its
edges or sides or other limited portions as may be predetermined:
(3) The furnishing of a light, easy, comfortable plaister, which (unlike most,
plaisters of any considerable size, and which cling to the skin by their entire or
nearly entire surface) will not painfully contract the skin or be difficult to remove :
(4) The availing of all the advantages due to perforations (if perforations be
availed of), but in a novel and better manner than usual, and without weakening
the structure of the plaister:
(5) The opportunity of medicating at will the above-named fleecy material, and
this independently of any medication of the adhesive material, and
(6) A means for lessening at the sticking parts of the plaister the force of the
adhesiveness to the skin, while at the same time permitting enough of the sticking
quality to hold the plaister to its place without the need of any strings or band.
The plaister may be made in any desired shape or form.
In the drawings, which will serve to illustrate an efficient means for practising
my invention,
Figure 1 shews a quadrangular form, and
Figure 2 a circular form of my improved plaister, having the sticking surface at
the margin.
Figures 3 and 4 shew the same forms with the sticky surface between as well as
at the margin.
Figure 5 is a section on the line a of Figure 1 or Figure 2.
Figure 6 is a section of a plaister having a sticking surface at and between its
margin: 1 edge or edges; and
Figure 7 is a portion of a parforated plaister.
In carrying out my invention I employ a textile backing piece A on the front

page_text: face of which is placed the medicated material and the whole may, if desired, be
perforated with numerous holes c, made either through the cloth or through the
Acecy material hereinafter mentioned, or through both. Cotton, wool or kindred
fibre or fleece D, is laid over and clings to all the surface of the material except at
those parts e, e, which are to adhere to the person.
It will be seen that my improved plaister is always ready, and in a permanent
and portable form for immediate use, and may be made of any desired size or shape;
and that the fleecy material may at any time he medicated with any desired
medicament, that it is easily applied to any desired part of the person, that it
adheres to the skin only at certain portions and such only as are enough to hold it
in place, that the cotton or equivalent material not only holds its own place without
sticking, but also interposes between such non-medicated sticking material and the
flesh, permitting of free movements of the body. It also gives all the benefit
derivable from the warming properties of the fibre, and allows the medication of
such fibre, if desired.
Another advantage is that the plaister can be folded up flat without injury, and
shipped in quantities or mailed in a letter, the non-adhesive cotton or fibre
preventing the folded faces from sticking together; hence it can be readily opened
or unfolded when wanted for use; and this folding tends to preserve and retain
the healing qualities of any medicaments which may have been previously applied
to the fleece..
With my invention, the sticking portion of the plaister merely serves to confine
the plaister to the body or keep it in close contact therewith, while the fleecy layer
of cotton, &c., when properly medicated, furnishes the active medicinal principles.
which tend to effect the cure.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A medicinal plaister composed of a backing-piece, surfaced with an adhesive
material and having such surface, except that portion which is to cling to the
person, covered with a fleece or layer of medicated cotton, wool, or equivalent fibre,
held to the backing by such adhesive material, substantially as described.
2. A medicinal plaister composed of a medicated backing-piece, surfaced with an
adhesive material, and having such surface, except that portion which is to cling to
the person, covered with a fleece or layer of medicated cotton, wool, or equivalent
fibre, held to the backing by such adhesive material, substantially as shewn and
described.
