page_text: LETTERS PATENT to Gustav Jaeger, Physician at Stuttgart, Germany, for an
invention of "IMPROVEMENTS IN THE MANUFACTURE OR TREATMENT OF
TEXTILE MATERIALS, WEARING APPAREL, AND FURNITURE, FOR THE PURPOSE
OF MAKING THEM INODOROUS AND FOR PROTECTING BOLSTERED FURNITURE
AGAINST MOTHS."
PROVISIONAL SPECIFICATION left by the said Gustav Jaeger at the Office
of the Commissioners of Patents on the 5th May 1882.
"IMPROVEMENTS IN THE
GUSTAV JAEGER, Physician, at Stuttgart, Germany,
MANUFACTURE OR TREATMENT OF TEXTILE MATERIALS, WEARING APPAREL, AND
FURNITURE FOR THE PURPOSE OF MAKING THEM INODOROUS, AND FOR PROTECTING
BOLSTERED FURNITURE AGAINST MOTHS,"
My invention has for its object to protect wearing apparel and furniture against
the volatile substances given off by perspiration, which substances are injurious to
health, and also to protect bolstered furniture against moths. For this purpose I
coat all wooden surfaces exposed to the atmosphere with resinous or fatty
substances, so as to close the pores of the wood. I also make the bolsters of
furniture removable, by mounting them in a frame, the bottom of which is formed
by a metallic sieve or perforated plate, and cover the bottom of the bolsters by a
removable sheet of felt (placed between the bolster and the metallic bottom of the
frame) which serves as a base or support for the application of insect powder.
Textile materials and leather, if not already inodorous, can be made so according
to my invention by impregnating them with hydro-carbons, such as vaseline,
paraffin, wax, and ceresin, and fabrics made from materials thus treated, are
likewise inodorous. I have found that the injurious substances given off by
perspiration and which have a peculiar smell, are absorbed by most textile
materials of vegetable origin, but not by those of animal original origin, such as
hair or wool; consequently this treatment applies particularly to textile materials
of vegetable origin, such as cotton yarns.

GUSTAV JAEGER, Physician, at Stuttgart, Germany. "IMPROVEMENTS IN THE
MANUFACTURE OR TREATMENT OF TEXTILE MATERIALS, WEARING APPAREL, AND
FURNITURE FOR THE PURPOSE OF MAKING THEM INODOROUS AND FOR PROTECTING
BOLSTERED FURNITURE AGAINST MOTHS,"
My system is based principally on the following principle.
The specific and individually different odorous substances contained in the
exhalations and eliminations of the human body take an important part in his
sanitary condition. Of such odorous substances the body produces two kinds of
opposite effects, namely:-
=
1. Malodorous or nauseous substances (Odours of soiled linen and excrements)
the incomplete elimination of which has a very unfavorable effect on the mental
and physical condition of man. They are poisonous to the organism which produces
them.
2. Such volatile matters only recently known or noticed which are for their
producer of an agreeable musk-like odour and which for their enlivening and
restoring effects might be called Life-substance, restorative of the constitution or
self medecine such volatile matters having thoroughly advantageous effects on the
general condition of man.
Not only does the human body communicate such volatile matters to the
surrounding air, but he imparts them also to all objects with which he comes into
contact. The different articles of clothing and household furniture, however are not
equally susceptible to such gases. Some materials do not absorb any of these
substances to a remarkable degree (such as metal, glass, polished, painted or oiled
wood) others absorb poisonous gases only viz all goods made of vegetable fibres viz
Linen, cotton, hemp, jute, paper, raw wood as well as silk and leather, others
however absorb the agreeable and salubrious gases (such as animal wool, hairs,
feathers, horn)
'
Experience and experiments have convinced me that the variations of motility
in imvoluntary motive apparatus-used in my new method of examination the so
called neural-analysis, and the variations of motility in imvoluntary motions,
especially of the movements of the pulse recognised long ago by Physiologists and
Pathologists, may be traced to the same source, the pulse curve is therefore also a
neural analytical curve. By experiments I have found
1. The inhalation of an odorous substance is sufficient to cause a variation in the
pulse-curve.
2. The pulse varies whenever another odorous matter is inhaled, and the
variation is specific for every odour, Aconite, Salt, Alcohol, Pork, and Beef all affect
the pulse differently.
3. The physiological effects of the so called homopathic dilutions, even of the
most extreme ones, may be recognised in the osmograms of the pulse as distinctly
as in the osmograms obtained by the pressure of the finger.
For instance, the pulse-curve obtained with a homopathic dilution of salt equal
to 1:4000 differs essentially but chiefly by its important decrease in the height of
the curve from the corresponding pulse-curve of alcohol. These facts proove that
in the choice of clothes, furniture or household utensils their respective quality and
susceptibility in absorbing odorous matter must be taken into consideration. The
poisonous or beneficient odorous matter absorbed by them even if extremely
rarefied affect the human organism and may therefore become advantageous or
disadvantageous to the condition of man.
In consideration of the above I produce furniture remaining free from disagreeable

page_text: odours, and if bolstered free from moths. In the manufacture of such furniture
two points must be considered.
1. The treatment of wood. If a piece of furniture is to remain free from
disagreeable odours. the wooden parts must not as is usually the case, be polished,
painted or otherwise coated on the visible parts only but all surfaces coming into
contact with the atmosphere for instance the inside of furniture specially such as
used as receptacles for clothes and victuals must be equally subjected to a treatment
causing the pores of the wood to be closed. For this purpose all, oils lacks, resins
or polishes may be used, these substances having the peculiarity to absorb and
retain only the agreeable odours.
2. The treatment of the bolstering in bolstered furniture.
To manufacture bolstered furniture remaining free from disagrecable odours,
besides metal, and wood having been treated as described under 1., textile fabrics
and bolster material made from animal hairs or feathers only, should be used. To
keep such bolstered furniture free from moths, the bolstering is not firmly attached
to the frame but removable; such furniture may be made in two different
constructions, represented in the accompanying drawing by vertical sections of the
seat of a bolstered chair. Fig. 1. represents a construction with helical springs.
A, is a vertical section of the wooden frame. B, represents a grating made of flat
irons upon which the helical springs are fastened, C is a sheet of felt spread over
the helical springs. D is the movable bolstered seat. Fig. 2 represents a cheaper
construction without helical springs. A¹. is a vertical section of the wooden frame,
B. a wire netting, C. a movable sheet of felt and D¹. the movable bolster.
Security from moths is due to the following fact. 1. The bolster is movable and
may be brushed on all surfaces which prevents the moths from settling down in
inaccessible places. 2. Insect powder may be strewn at any time on the felt-
sheet C or C, as well as between the joints of A and D, respectively A¹. and D¹.
This prevents the settling down of moths. The seats of sofas are treated in the
same way.
The backs of the sofas are movable bolsters leaning against a wooden frame, the
back bolsters of chairs are provided with loops in the 4 corners by which they are
fastened to the heads of 4 nails see fig. 3.
In reference to the novelty of the process it may be observed.
1. All the surfaces of the wood exposed to the atmosphere are coated, whereby
the pores of the wood are closed, while in the most elegant furniture hitherto
manufactured the hind part and under part of the frame remain in a raw state.
2. The bolstering consists exclusively of animal hairs. In all bolstered furniture
hitherto manufactured hempen cords and strings are fastened over the helical
springs and textile fabrics or fibres of vegetable origin used as coverings of the
bolster material.
3. New is also, not the moveable bolsters as such, but that owing to this and
the introduction of an independant sheet of felt between the metal base and the
movable seat it is possible to strew Insectpowder on the most important place viz.
on the underside of the bolster which is impossible in ordinary furniture.
If however textile materials or fibres of vegetable origin are to be used for
clothes and furniture such materials, to remain free from disagreeable odours, must
not only be coated on the surface with substances remaining free from odours, but
must be thoroughly impregnated with matters remaining naturally free from
odours.
This process relates to :-
I. Textile materials (woven fabrics, threads and bolster materials) and leather
material (raw materials).
II. Clothes (outer garments and under garments, hats, shoes, collars, cuffs
braces,) and bedding.
III. bolstered furniture with fixed bolsters.
I. Process for the treatment of raw materials.
In the human atmosphere the following materials become malodorous.

page_text: 1. All threads, yarns and textile fabrics of vegetable origin produced in the
hitherto usual way.
2. Materials produced from horny animal substance if they are impregnated
with dyes or other finishing substances liable to become malodorous (such sub-
stances are, wood extracts, paste, glue, gum and fats liable to become rancid).
The materials mentioned under 1 and 2 lose this bad quality, if they are impreg-
nated with solid hydro carbons such as Vaseline, Paraffin, fossil wax, or real wax
(animal or vegetable), or a mixture of both, for instance Ceresin."
"
In the manufacture of textile fabrics wax has been applied to the surface only
for the purpose of obtaining lustre and stiffness for instance in the case of Satins
and glazed threads; compared with it my process is new as regards purpose and
method, for firstly the purpose is not physical as above but chemical viz: rendering
materials inodorous, secondly in the manufacture of satin and glazed thread the
wax is applied on the surface only, whereas in this process the aim is complete
impregnation, while avoiding the retention of the impregnating substance on the
surface.
II. Method of manufacturing composite clothes and beddings.
My method consists in using exclusively such materials which remain free from
odours viz, materials to which the human atmosphere does not impart a disagreeable

page_text: 4. Deodorizing threads, textile and leather fabrics by impregnating them with
paraffin, wax, vaseline or ceresin.
5. Deodorizing clothes and bedding by using materials naturally inodorous or
materials rendered inodorous by impregnation.
6. Using for bolstered furniture materials rendered inodorous by impregnation.
The whole substantially as described.
In witness whereof I, the said Gustave Jaeger have hereunto set my hand
and seal this twenty eighth day of October A.D. 1882.
