page_text: LETTERS PATENT to Manuel Leopold Jonas Lavater, of the Strand, in
the County of Middlesex, India-rubber Manufacturer, for the Invention
of "IMPROVEMENTS IN APPARATUS KNOWN AS INJECTION BOTTLES, AND IN
PNEUMATIC DISCS USED IN APPARATUS FOR ADHERING TO GLASS AND OTHER
IMDED MEADT. STROMANATO "
Sealed the 16th March 1860, and dated the 28th September .1859.
PROVISIONAL SPECIFICATION left by the said Manuel Leopold Jonas
Lavater at the Office of the Commissioners of Patents, with his Petition,
on the 28th September 1859.
I, MANUEL LEOPOLD JONAS LAVATER, of the Strand, in the County of
Middlesex, India-rubber Manufacturer, do hereby declare the nature of the
Invention for "IMPROVEMENTS IN APPARATUS KNOWN AS INJECTION BOTTLES, AND
IN PNEUMATIC DISCS USED IN APPARATUS FOR ADHERING TO GLASS AND OTHER
IMPERMEABLE SUBSTANCES," to be as follows:-
This Invention has for its object improvements in apparatus known as.
injection bottles, and in pneumatic discs used in apparatus for adhering to
glass and other impermeable substances.
In the construction of injection bottles, in place of making the india-.
rubber bottles, as heretofore, so as to receive and have fixed therein tubular :
mouthpieces of wood or other, material, through which the bottles are filled,

page_text: and in which the clyster or such like pipes are fixed, the necks of india-
rubber bottles are, according to my Invention, cast with such an enlargement
or thickening at the outer ends thereof as to dispense with the use of the
separate or distinct mouthpiece of wood or of other material heretofore used,
the edges of the india-rubber bottles fitting tightly to the exterior of the
clyster or such like pipe; or, in the construction of injection bottles, india-
rubber bottles of the ordinary form may be used, and the clyster or such like
pipe may be fitted into it, the exterior of the pipe being of larger diameter
than usual, so as to fit tightly into the mouth of the bottle.
In making india-rubber discs for pneumatic apparatus for adhering to glass
and other impermeable substances, each india-rubber disc is made of greater
thickness at the outer edges or circumference than in the centre, and so that
by deflecting the central portion of a disc within the limits of the thickness of
its circumference a sufficient vacuity will be obtained, and consequently such
discs will admit of having flat plates fixed to their backs in place of hollow
cups or chambers, as has heretofore been the practice.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Manuel Leopold Jonas Lavater in the Great Seal Patent
Office on the 28th March 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, MANUEL
LEOPOLD JONAS LAVATER, of the Strand, in the County of Middlesex, India-
rubber Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-eighth day of September, in the year of our
Lord One thousand eight hundred and fifty-nine, in the twenty-third year of
Her reign; did, for Herself, Her Heirs and successors, give and grant unto
me, the said Mannél Leopold' Jonas Lavater, Her special licence that I, the
said Manuel Leopold Jonas Lavater, my executors, administrators, and
assigns, or such others as I; the said Manuel Leopold Jonas Lavater, my
executors, administrators, and assigns, should at any time agree with, and no
others, from time to time and' at all times thereafter during the term
therein expressed, should and lawfully might make; use, exercise, and vend,
within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man; an Invention for "IMPROVEMENTS IN APPARATUS
KNOWN AS INJECTION BOTTLES, AND IN PNEUMATIC DISCS USED IN APPARATUS FOR
ADHERING TO GLASS AND OTHER IMPERMEABLE SUBSTANCES," upon the condition

page_text: (amongst others) that I, the said Manuel Leopold Jonas Lavater, my
executors or administrators, by an instrument in writing under my, or
their, or one of their hands and seals, should particularly describe and
ascertain the nature of the said Invention, and in what manner the same was
to be performed, and cause the same to be filed in the Great Seal Patent
Office within six calendar months next and immediately after the date of the
said Letters Patent.
.
NOW KNOW YE, that I, the said Manuel Leopold Jonas Lavater, do
hereby declare the nature of the said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained in and
by the following statement thereof, that is to say :-
This Invention has for its object improvements in apparatus known as
injection bottles, and in pneumatic discs used in apparatus for adhering to.
glass and other impermeable substances.
In the construction of injection bottles, in place of making the india-rubber
bottles, as heretofore, so as to receive and have fixed therein tubular mouth-
pieces of wood or other material, through which the bottles are filled, and in
which the clyster or such like pipes are fixed, the necks of india-rubber bottles.
are, according to my Invention, cast with such an enlargement or thickening
at the outer ends thereof as to dispense with the use of the separate or
distinct mouthpiece of wood or of other material heretofore used, the edges
of the india-rubber bottles fitting tightly to the exterior of the clyster or such
like pipe; or, in the construction of injection bottles, india-rubber bottles of
the ordinary form may be used, and the clyster or such like pipe may be fitted
into it, the exterior of the pipe being of larger diameter than usual, so as to
fit tightly into the mouth of the bottle.
In making india-rubber discs for pneumatic apparatus for adhering to glass
and other impermeable substances, each india-rubber disc is made of greater
thickness at the outer edges or circumference than in the centre, and so that
by deflecting the central. portion of a disc within the limits of the thickness of
its circumference a sufficient vacuity will be obtained, and consequently such
dises will admit of having flat plates fixed to their backs in place of hollow
cups or chambers, as has heretofore been the practice.
Having thus stated the nature of my Invention, I will proceed more fully
to describe the manner of performing the same.

page_text: thereof. From these views it will be seen that the ordinary mouthpiece of
wood or other material, which has heretofore been fixed in the neck of such
a description of bottle, in order to receive the end of a clyster or other pipe,
is dispensed with, and in place thereof the neck or mouthpiece of the bottle
itself is made of greater substance, in order that, by the greater strength
thereof, the holding of the end of a clyster or such like pipe may be made
more secure than when a wood or other mouthpiece is used to receive the end
of a clyster or other pipe, as was formerly the case. The bottles, as here-
tofore, are made of vulcanized or converted india-rubber. a is the elastic
mouthpiece, and 6 a clyster pipe fitted therein, the hole or passage in the
mouthpiece being smaller in diameter than the exterior of the clyster pipe,
so that when the end of the clyster pipe is forced in, the elastic mouth-
piece embraces the same very strongly, and in such manner as to prevent the
passage of the fluid in that direction when the bottle is pressed in with a
view to force the fluid through the clyster pipe. In the Drawing the ordinary
form of clyster pipe is shewn, but, if preferred, the end may be made larger,
and the mouthpiece or neck of the bottle also larger than that shewn, and
made similar to those heretofore made when intended to receive and have
fixed therein a mouthpiece of wood or other material, but in this case also the
thickness or substance of the india-rubber is to be made of greater strength,
and sufficient to hold the end of the clyster or other pipe securely.
Figure 3 shews a plan and section of a disc of india-rubber (by preference
vulcanized or converted india-rubber) suitable for pneumatic apparatus for
adhering to glass and other impermeable surfaces for which plain discs of
india-rubber have heretofore been used. Figure 4 shews a plan and section
of another form of india-rubber disc; and I would state that the shape may
be varied, but the circular or elliptical form is preferred; but in all cases they
are to be made similar in respect to having their outer edges or parts thicker
or of greater substance than the central parts, and they should also in all
cases be made similar in respect to having tubular portions produced at the
centres, in order more securely to attach the end of the stem air-tight thereto.
These india-rubber discs are formed in moulds, and retained therein during
the process of vulcanizing or curing the same by hand, as is well understood,
when making other articles of vulcanized or cured india-rubber in moulds.
I would remark, that although it is preferred to employ india-rubber and
sulphur without the admixture of other matters, I do not confine myself
thereto, as other substances may be combined therewith.
Having thus described the nature of my Invention and the manner of
performing the same, I would have it understood that what I claim is,-

page_text: First, the manufacture of flexible elastic india-rubber bottles with mouth-
pieces, as herein described.
And, secondly, I claim the manufacture of india-rubber discs for pneumatic
apparatus, with extra thickness or substance at the edges, and tubular centres,
as herein described.
In witness whereof, I, the said Manuel Leopold Jonas Lavater, have
hereunto set my hand and seal, this Twenty-seventh day of March,
in the year of our Lord One thousand eight hundred and sixty.
L. J. LAVATER. (L.S.)
