page_text: Improvements in Sanitary Conveniences for Travellers.
I, ERNST DRESEN, of Bonn-on-Rhine, Germany, Merchant, do hereby declare the
nature of this invention to be as follows:-
The present invention concerns a necessity apparatus which can be folded so as
to occupy a very small space for travelling conveniences, and quickly prepared
for use; it is provided with a paper bag which can be instantaneously detached
after use.
The apparatus is composed of a metallic circle formed of two semi-circles of
such a profile that the circle has a circular gutter opened at the top; the two
semi-circles are articulated to one another so that they can fall on each other.
One of the semi-circles is provided with two pivotable rods forming a handle to
hold the apparatus and the other semi-circle is connected by means of a hinge
with spiral spring with a third semi-circle to which a fourth semi-circle is articu-
lated; the two latter form a circle which can fall upon the former in the gutter,
in which, for the functioning, the edges of a conical strong paper bag are intro-
duced; by falling on this gutter the second circle formed by the two last-mentioned
semi-circles, fix and hold the edges of this paper-bag in the gutter: this fixity
is secured by a small bent spring plate dropping on the circles thus arranged; the
apparatus is then ready for use; for this it is placed on a stool which has a hole
in it and which can be taken to pieces for travelling and when the apparatus has
been used, it can be lifted from this stool and be substituted by a wooden plate
which folds in two for the transport, and which allows the stool to be used as a
seat.
When the apparatus has been used, the stool is removed and the spring plate
holding the circles in each other is drawn back: the second circle under the
influence of its spring, leaves the gutter and falls on the outside; the paper bag
and its contents fall by their own weight.
To put the apparatus into the travelling bag, it is first folded as for working
thus forming a single circle, one half of which is afterwards folded on the other
half, by means of the articulations with which the circles are provided; the two
rods serving as handles, and which are for that purpose bent in the same radius
as the periphery of the first semi-circles are likewise dropped on the periphery
of the latter; the stool is taken to pieces, the rim of the seat is folded as also the
wooden plate and the all is arranged in the travelling bag made of cloth or any
suitable material.
The conical bags may, be made of strong paper with a water-proof coating or of
any suitable water proof material neither too expensive nor too heavy.
They are stored in the travelling bag in sufficient quantity according to the
duration of the journey.

page_text: I, ERNST DRESEN, of Bonn on the Rhine, Germany, Merchant, 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 a sanitary convenience which is capable of being
folded so as to take up very little room and so as to be capable of being carried by
travellers and which is also capable of being quickly got ready for use, the
apparatus being provided with a bag of impervious paper which can be instan-
taneously removed therefrom after use.
The apparatus may be fitted to a stool or to a folding seat having a back arranged
in such a manner as to be adapted when detached from the said seat to form a
small bench or rest for the feet.
The accompanying drawings illustrate by way of example one mode of carrying
out the invention. In these drawings, Figure 1 is a plan of the apparatus, opened
to receive the paper bag. Figure 2 is a plan of the same in its position of working.
Figure 3 is a plan of the apparatus folded together for transport in a travelling
bag. Figure 4 is an elevation of the same folded as shown in Figure 3.
Figure 5 is a vertical section in a plane M, N, of Figure 1. Figure 6 is a vertical
section in the plane O, P, of Figure 1. Figure is a vertical section of the
plane Q, R, of Figure 1. Figure S is a vertical section of the apparatus on the
plane X, Y, of Figure 2 and showing in vertical section the paper bag in the
operative position. Figure 9 shows a stool upon which the apparatus is arranged.
Figure 10 shows the movable seat or top of the stool which can be replaced upon
the latter after the apparatus has been removed after it has been used. Figure 11
is a front elevation of a folding seat to which the apparatus shown in Figure 1
can be fitted, the parts being shown in the position of use. Figure 12 is a side
elevation of the same. Figure 18 is a plan of the same. Figure 14 shows the
same seat folded together for transport. Figure 15 is an elevation of the back of
the above seat detached from the latter. Figure 16 shows the said back opened out
so as to serve as a small bench for resting the feet thereon!. Figures 17 and 18 are
views of the cover which may be employed to cover over the aperture in the afore-
said seat in order to use it in the usual manner as an ordinary seat.
The apparatus consists essentially of a metal hoop composed of two half
hoops A and A Figure 1 shaped in cross section as shown in Figure 7 and forming
a circular groove which is open at the top. These half hoops are connected
together by means of lugs J movably jointed one to the other in such a manner
that one of the half hoops can be folded back upon the other. Upon periphery
of the half hoop A¹, and at an equal distance from the two joints above mentioned,
there are soldered two plates F, F, to which are fixed two small vertical
cylinders G, G, in which engage with slight friction the ends bent at right angles
of two rods H which constitute together the handle for operating the apparatus.
These two rods which are curved to the same radius as the periphery of the half
hoop A, are capable of pivotting on their ends that are engaged in the
cylinders G, G, and of being folded against the periphery of the above mentioned
half hoop when the apparatus is folded for packing into its bag or when the said
apparatus is placed in the folding seat. In order to operate the apparatus, the
outer ends of the rods H, H, are held one against the other by means of a bar I
that forms a spring hook. The inner ends of the plates F, F, are bent at right
angles and are perforated to receive the ends of a small pin or trunnion to which
is fixed the end of a coiled spring that is attached at its other end to a bent plate 1)
and keeps the latter bearing in its normal position upon the top of the hoop A¹
for the purpose hereinafter described..

page_text: On the part of the half hoop A and diametrically opposite to the point where the
spring plate D is arranged, there is movably jointed another metal half hoop B
formed in cross section as shown in Figure 6. This joint is effected by means of
plates S and S of which the two first S, are soldered on the periphery of the
half hoop A, whilst the second, S¹, is soldered on the half hoop B. A coiled
spring Carranged between the two half hoops tends to keep the hoop B in the
position shown in Figure 1.
To the half hoop B there is movably jointed by means of two small rivetted
axles K, K, a last half hoop B¹ consisting of a flat bar of iron, Figures 1 and 5.
This latter is capable of folding by turning on the two joints K, K, in such a
manner as to enter the circular groove formed by the half hoop B, when it is
required to fold the apparatus for packing away in its bag.
The apparatus being opened as shown in Figure 1, there is introduced into the
hoop A, A, a paper bag of conical form with its apex downwards. The edges
of the bag are turned down into the circular groove formed by the half hoops A
and A. Pressure is applied to the bar D which turning on its spring pin uncovers
that part of the groove which it had previously covered over. The hoop B, B¹.
is turned down on to the hoop A, A. This hoop entering the circular groove A, A',
keeps in its place the paper bag by bearing upon its edges in the groove, and the
rigidity of the arrangement is ensured by the spring bar D) which is turned down
on to the hoop.
When the apparatus is being used, it is sufficient to bear upon the bar D in order
to move it away. The bar B, B, pulled by the spring C, turns on its pivots and
turns down outwardly into the position shown in Figure 1, and the bag being
drawn by the weight of the matters which it contains becomes released from the
hoop A, A, and falls.
In order to fold the apparatus for the purpose of packing it away into its bag,
it is first folded as shown in Figure 2 as if it was being got ready for use. The
half hoop B enters the groove of A which is turned with its groove uppermost,
whilst enters the groove of A!. Then the half hoop A is turned on the
pivots J, J. The half hoop B embraces the hoop B' in the groove of A¹, and the
hoop A rests upon the hoop A' as shown in Figures 3 and 4.
The hook I is then
unhooked, and the rods H, H, are folded against the periphery of the hoop A¹.
In order to use the apparatus when the paper bag has been fitted therein, it
is placed upon a stool consisting of an annular part U which is arranged to support
it and which is itself supported by four feet V which are fixed to the annular
part by means of their screw threaded ends. This stool, as will be seen, is easy
to take apart, and it can be used as an ordinary stool when the apparatus has
been removed, by substituting for the latter a seat W which is capable of being
folded as shown in Figure 10 for packing away with the other parts in a travelling
bag.
Finally, the apparatus shown in Figures 1 to 4, may be fitted to a seat arranged
in such a manner as to be capable of being completely folded for packing in a
travelling trunk or even in a valise. The seat is composed of a plate under
which are fixed two longitudinal pieces d,. d. Upon these are jointed in the
manner indicated in Figures 11 and 12, the feet by means of metallic plates m
each provided with an extension bent at right angles that maintains the corre
sponding foot at a given angle when the seat is unfolded. The feet are stayed
together in pairs by means of rods q. The plate a is perforated at the centre
with a circular aperture i of suitable diameter and it is formed with a circular
shoulder h upon which the portable apparatus shown in Figures 1 to 4 is placed.
The seat is provided with a back consisting of an open-worked plate b hinged to
one of the longitudinal sides of the plate a forming the seat, by means of two
pins and it can be very easily detached from the seat. Two rods c, c,
movably jointed at one of their ends to the sides of the plate a and having at their
ends an aperture in the form of a button-hole are attached by means of these button-
holes to two small wood screws 6 screwed in the sides of the plate c in such a

page_text: manner as to keep the latter in its upright position. When the back bis removed
from the seat, the said back can be used as a small bench for resting the feet
thereon. For this purpose it is provided with four small rods t, t, which fold
down as shown in Figure 16, to form the four feet of the small bench. A cover
shown in Figures 17 and 18 is placed upon the aperture in the plate a when it is
desired to use the seat as an ordinary seat.
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 sanitary convenience capable of being folded in such a manner as to take
up very little room and so as to be capable of being carried by travellers and
being provided with a bag of impervious paper or any other suitable material
which can be detached instantly after the apparatus has been used, as set forth.
(2) In a sanitary convenience as claimed in Claim 1, the arrangement of two
half hoops movably jointed one to the other and forming a circular groove into
which engage the edges of a paper bag designed to receive the matters, one of the
two half hoops being provided with two curved rods constituting the operating
handle and being capable of folding against the periphery of the said half hoop, as
set forth.
(3) In a sanitary convenience as specified in Claim 1, the arrangement of two
half hoops movably jointed together the one being constituted by a curved flat
bar of iron, whilst the other has a hollow form in cross section in such a manner
that the half hoop of flat bar iron can fit in the other half hoop by causing the first
to make half a revolution on its pivots, the two half hoops forming a hoop which
is movably jointed to the one referred to in Claim with an intermediate spring
and which when it is turned down on to the hoop referred to in Claim 2, enters
the circular groove formed by the latter for the purpose of fixing the paper bag
in its operative position, the said hoop when turned down being kept in its position
by means of a spring bar, and turning outwardly by the action of the spring of
its movable joint when the aforesaid spring bar is removed, after having used the
apparatus, and thus allowing the paper bag to become detached from the apparatus
by its own weight, as set forth
(4) In a sanitary convenience as specified in Claim 1, the arrangement of the
several cross sectional forms of the half hoops of irou, and of the several movable
joints of the apparatus, for allowing the apparatus to be folded as shown in
Figures 3 and 4 with a view to its being packed in a travelling bag, as set forth.
(5) In a sanitary convenience as specified in Claim 1, the arrangement of a stool
that can be taken to pieces, provided with a circular part for supporting the
apparatus, which latter can be replaced when not in use, by a top or seat which
allows the stool to be used in its usual manner, as set forth.
(6) In a sanitary convenience of the kind specified in Claim 1, the arrangement
of a seat capable of being folded together in such a manner as to be capable of
being carried in a travelling bag and upon which the apparatus can be fitted, and
being provided with a removable back which is arranged to serve as a small
bench for the feet, as set forth.
