En the Matter of a Patent granted to Manuel Leopold Jonas Lavater,
India-rubber Manufacturer, of 23, Holywell Lane, Shoreditch,
London, E.C., for the Invention of "THE APPLICATION OF THE
PRINCIPLE OF EXHAUSTING AIR, AS USED IN PLATE HOLDERS, BREAST
PUMPS, FOR PEGS," bearing date the Seventh day of January, One
thousand eight hundred and fifty-eight, and which said Letters
Patent have become and are now vested in the said Manuel Leopold
Jonas Lavater and Christopher Walton, of Ludgate Street, in the
City of London, Goldsmith.
DISCLAIMER AND MEMORANDUM OF ALTERATION proposed to be
entered by the said MANUEL LEOPOLD JONAS LAVATER and CRISTOPHER
WALTON, as such Patentee and Assignee as aforesaid, pursuant to the
Statutes in that case made and provided.
WHEREAS the said Patentee and Assignee have been advised that the
title and Specification of the said Invention are ambiguous and uncertain,
and that it is doubtful whether the Specification does not claim more than
was new at the date of the said Letters Patent, for which reason we, the said
Manuel Leopold Jonas Lavater and Christopher Walton, wish to disclaim
and alter the title and Specification of the said Invention, as follows:-

OF
THE
upon

page_text: my, or their, or one of their hands and scals, 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 my said 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 consists in the application of the principle of pneumatics
to cause pegs, whether to act as brackets or other similar articles, to adhere
mechanically on solid surfaces, such as glass, walls, pannels, and furniture.
The said pneumatic pegs, whether in the form of brackets or other similar
articles, may be adapted (with accessories, such as holes, rings, hooks,
nails, springs, buttons, slides, screws, and other similar means,) for the
purpose of receiving and supporting or fastening articles, such as chandeliers,
candlesticks, sconces,
niture,
fixtures for gas
lamps, vases, shelves,
^
shaving or other glasses, fur-
reflectors, stands for hatters, milliners, drapers, and
other trades, and generally all articles or goods that are required to be
supported on pegs fixed to solid surfaces.
Process of manufacture.-On the under side of an inverted wooden cup
is fixed an india-rubber disc, and on the top of the said cup is placed a
rotary cylinder, on the inside of which is formed a female screw or screw
mut. The cylinder and cup are traversed through the centre by a stem,
the outer end of which is formed into a screw working in the screw nut of
the cylinder; to the other end of the stem is attached a flat button, which
is fastened air-tight to the disc of india-rubber.
peg,
The method of using the above-named pneumatice pegs is as follows:-
The disc should be placed on any solid surface, when, by turning the
cylinder, it acts on the stem, which draws the india-rubber disc into the
cup, and creates a vacuum, greater or less according to the extent the screw
is moved, and the peg will remain secure. For disadhering the said
unscrew the cylinder or nut till the disc is forced flat.
methods of moving the disc may be used instead of the aforesaid screw, but
I prefer the said screw. In manufacturing the above pegs, whether in the
form of brackets or other similar pneumatic instruments, I do not confine
myself to any express shape, form, or size (which will vary according to
Other known

page_text: r application and use,) or to the use of any particular kind of materials
he course of manufacture.
In witness whereof, I, the said Manuel Leopold Jonas Lavater, have
hereunto set my hand and seal, this Twenty-fifth day of June, in
the year of our Lord One thousand eight hundred and fifty-
eight."
In witness whereof, we, the said Manuel Leopold Jonas Lavater and
Christopher Walton, have hereunto set our hands and seals, this
Twenty-third day of November, in the year of our Lord One thou-
sand eight hundred and fifty-eight.
To the Clerk of the Patents for England.
I hereby grant my Fiat, giving leave to the within-mentioned Manuel
Leopold Jonas Lavater and Christopher Walton to file in the Great Seal
Patent Office, with the Specification to which the same relates, the within-
written Disclaimer and Memorandum of Alteration.

PROVISIONAL SPECIFICATION left by the said Manuel Leopold Jonas
Lavater at the Office of the Commissioners of Patents, with his Petition,
on the 7th January 1858.
I, MANUEL LEOPOLD JONAS LAVATER, India-rubber Manufacturer, of
23, Holywell Lane, Shoreditch, London, E. C., do hereby declare the
nature of the said Invention for "THE APPLICATION OF THE PRINCIPLE OF
EXHAUSTING AIR AS USED IN PLATE HOLDERS, BREAST PUMPS, POR PEGS," to be as
follows:-
I have applied for pegs the principle of exhausting air as used in plate
holders, breast pumps, so that an exhausting apparatus made in the shape of
pegs, I apply on window glasses, walls, for hanging articles on; I therefore
claim as my Invention the application of the said principle for pegs of all
shapes.

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 "THE APPLICATION OF THE PRINCIPLE OF EXHAUSTING AIR
(PNEUMATICS), AS USED IN PLATE HOLDERS, BREAST PUMPS, CUPPINGS, FOR INSTRU-
MENTS TO BE CALLED SELF-ADHERING PEGS, OR PNEUMATIC BRACKETS, OR PNEUMATIC
INSTRUMENTS OR UTENSILS," upon the condition (amongst others) that I, the
said Manuel Leopold Jonas Lavater, 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

and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Manuel Leopold Jonas Invater, do
hereby declare the nature of my said 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 consists in the application of the principle of pneumatics to
cause pegs, brackets, and other similar articles to adhere mechanically on
solid surfaces, such as glass, walls, panels, furniture; the said pneumatic pegs
brackets, and other similar articles, adapted with accessories, such as holes,
rings, hooks, nails, springs, buttons, slides, screws, and other similar means, for
the purpose of receiving and supporting or fastening articles, such as chan-
deliers, candlesticks, sconces, lamps, vases, shelves, shaving or other glasses,

page_text: PROCESS OF MANUFACTURE.
On the edge of a wooden cup is fixed an india-rubber disk (as used in plate
holders), and on the top of the said cup is placed a rotary cylinder, the inside
of which is a female. screw or knot. The cylinder and cup are traversed
through the centre by a square stem, the end of which is a screw working
in the knot of the cylinder; to the other end of the stem is attached a flat
button which is fastened to the disk.
The method of using the above-named pneumatic utensils are as follows:-
The disk should be placed on any solid surface, when, by turning the cylinder,
it acts on the stem which draws the india-rubber disk and creates a vacuum,
greater or less according to the modulation of the screw, which, when done,
the utensil will remain secure. For disadhering the said utensil, unscrew the.
cylinder till the disk is forced flat.
Other known methods of creating a vacuum. I use instead of the aforesaid
screw, such as, india-rubber bottles or balls, pumps, but I prefer the said screw,
which I apply also to breast pumps, cuppings, plate holders, and other similar.
instruments and utensils; and in manufacturing the above pegs, brackets
breast pumps, cuppings, plate holders, and other similar pneumatic instru-
ments and utensils, I do not confine myself to any express shape, form,
or size, (which will vary according their application and use); also I use of
all kind of materials in the course of manufacture.
In witness whereof, I, the said Manuel Leopold Jonas Lavater, have
hereunto set my hand and an seal, this Twenty-fifth day of June, in
the year of our Lord One thousand eight hundred and fifty-eight.
MANUEL LEOPOLD JONAS LAVATER. (L.S.)
