and Birkbeck, Patent Agents and Engineers, of 34, Southampton

Invention of "IMPROVEMENTS IN COPYING PRESSES."—A communication

PROVISIONAL SPECIFICATION left by the said John Garrett Tongue
at the Office of the Commissioners of Patents, with his Petition,
on the 14th October 1874.
I, JOHN GARRETT TONGUE, of the Firm of Tongue and Birkbeck,
Patent Agents and Engineers, of 34, Southampton Buildings, Chancery
Lane, in the County of Middlesex, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN COPYING PRESSES," a communication
to me from abroad by Pierre Jacques Betting, of Paris, France, to be as
follows:
90

page_text: presses to all kinds of seats, such as arm and other chairs, foot and
other stools, in such manner as to leave space to place a book or register
therein, and, if required, springs, and which will bear the weight and
movement of a person sitting thereon, the said seats being used either
as an ordinary seat or as a copying press when required. By these
means a new and useful article is obtained of a twofold character.
presses to an
Kinus of seats, such as arm and owner спашот 1000 ли
other stools, in such manner as to leave space to place a book or register
therein, and, if required, springs, and which will bear the weight and
movement of a person sitting thereon, the said seats being used either
as an ordinary seat or as a copying press when required. By these
means a new and useful article is obtained of a twofold character.
The top or seat of a chair constructed in accordance with this In-
vention is arranged to open by means of a hinge, a space being left to
receive a book or register.
The pressure may be given either by means of steel springs, india-
rubber, or other mechanical contrivance, or by the weight of the person
sitting down upon it.
The method of carrying out this Invention will be clearly understood
by referring to the annexed Drawings, which show its application to
an ordinary chair.
Figure 1 shows a side view of a chair suitably arranged and con-
structed for being used as a copying press; Figure 2 shows a front view
of the same; Figure 3 shows a longitudinal section of the same taken
on the line 1, 2, of Figure 2; in this Figure the seat is raised in order to
allow the book or register to be placed therein; and Figure 4 shows a
similar section, the seat being lowered ready to receive pressure on the
book or register. In all these Figures the same letters of reference
refer to the same parts.
a is the frame of the chair, having leggs 6 and back c. The two fore
leggs are only fitted with castors d in order to facilitate the removal of
the chair from one place to another; e is the bottom fixed on the
frame a; f is a drawer arranged in front of the chair in order to
receive the book or register g; h is a pressing plate or board having an
oscillating motion in order to press uniformly on the book notwith-
standing the different inclinations it may assume. This plate or board h
is balanced in the centre of a lever i, which is carried by and moves on
a fixed point j; k is the seat moving on pin joints or centres at 1, the
seat being formed either of cane or otherwise. The seat in lowering
acts on the extreme end m of the lever i. n is a chain or cord attached
to one of the extreme ends to the moveable plate h, and the other to

page_text: the seat k, for the purpose of lifting the plate h in order to admit of
the easy introduction of the book when being placed into the drawer.
In order to make use of the chair as a copying press it is only requisite
to lift the seat k, which by means of the chain » will lift one end of the
plate or board h, then draw out the drawer f in order to place the book
or register g therein, the drawer f is then pushed in order to place the
book under the plate h, as shown in Figure 4. This being done the
seat k is lowered, and when the person sits down upon it a pressure is
given which bears on the lever i and acts on the plato h, this plate
presses on the whole surface of the book or register y, and the letter
inserted into the book is copyed.
SPECIFICATION in pursuance of the conditions of the Letters Patent,.
filed by the said John Garrett Tongue in the Great Seal Patent
Office on the 14th April 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN.
GARRETT TONGUE, of the Firm of Tongue and Birkbeck, Patent Agents
and Engineers, of 34, Southampton Buildings, Chancery Lane, in the
County of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourteenth day of October, in the year of our
Lord One thousand eight hundred and seventy-four, in the thirty-eighth
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said John Garrett Tongue, Her special licenso that
I, the said John Garrett Tongue, my executors, administrators, and
assigns, or such others as I, the said John Garrett Tongue, my exe-
cutors, 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 COPYING PRESSES," (a communication to me from abroad by Pierre
Jacques Betting, of Paris, France,) upon the condition (amongst others)
that I, the said John Garrett Tongue, my executors or administrators,
$6

page_text: book or register. In all these Figures the same letters of reference
refer to the same parts.
a is the frame of the chair, having legs and back.c. The two fore
legs are only fitted with castors d in order to facilitate the removal of
the chair from one place to another; e is the bottom fixed on the
frame a; f is a drawer arranged in front of the chair in order to
receive the book or register 9; h is a pressing plate or board having an
oscillating motion in order to press uniformly on the book notwith-
standing the different inclinations it may assume. The plate or board h
is balanced in the centre of a lever i, which is carried by and moves on
a fixed joint j; k is the seat moving on pin joints or centres at 1, the
seat being formed either of cane or otherwise. The seat in lowering
acts on the extreme end m of the lever i; n is a chain or cord attached
to one of the extreme ends to the moveable plate h, and the other to
the seat k, for the purpose of lifting the plate & in order to admit of the
easy introduction of the book when being placed in the drawer.
Figures 5 and 6 show a vertical and horizontal section of a copying
press "chair" similar to that previously described. These Figures show
that the drawerf, in which the book or register g is placed, is moved by
an arm or pressing piece o sliding between two brackets p. The arm o,
when drawn in the direction shown by the arrow, will draw out the
book or register g as soon as the letter is copied.
Having thus fully described the construction of the chair and
apparatus it will be easily understood that in order to make use of the
chair as a copying press it is only requisite to lift the seat k, which by
means of the chain n will lift one end of the plate or board h, then draw
out the drawer f in order to place the book or register 7 therein; the
drawer fis then pushed in in order to place the book under the plate h,
as shown in Figure 4. This being done the seat k is lowered, and when.
the person sits down upon it a pressure is given which bears on the
lever i and acts on the plate h; this plate presses on the whole surface
of the book or register g, and the letter inserted into the book is
copied.
Having thus described the nature of the Invention communicated to
me by the said Pierre Jacques Betting, and the manner in which the
same is or may be carried into practice, what I claim is, the application

page_text: and utilization of seats of various kinds for the purposes of a copying
press, substantially in the manner herein-before described and repre-
sented in the Drawings hereunto annexed.
In witness whereof, I, the said John Garrett Tongue, have hereunto
set my hand and seal, this Fourteenth day of April, in the year
of our Lord One thousand eight hundred and seventy-five.
