PROVISIONAL SPECIFICATION left by the said William Brookes at
the Office of the Commissioners of Patents, with his Petition, on
the 4th May 1872.
I, WILLIAM BROOKES, of 62, Chancery Lane, London, in the County of
5 Middlesex, Patent and Registration Agent, do hereby declare the nature
of the said Invention for "IMPROVEMENTS IN MEANS FOR COMMUNICATING
MOTION AND PRESSURE TO PARTS OF PRESSES, COCKS, AND VALVES, VICES, AND
JACKS, WHICH IMPROVEMENTS ARE ALSO APPLICABLE IN COMMUNICATING MOTION
AND PRESSURE TO PARTS OF OTHER APPARATUS," (a communication to me

page_text: '
from abroad by Luis Alexandre Farjon, of Brussels, in the Kingdom of
Belgium, Engineer,) to be as follows:-
This Invention as communicated to me relates to means for commu-
nicating motion and pressure to the acting parts of presses, cocks, valves,
jacks, vices, and other apparatus wherein pressure and limited travel
are required; and it consists in the following mode of communicating
motion and pressure to the said parts as a substitute for the endless
screws, levers, cams, or eccentrics generally used for such purposes.
Two discs or plates or blocks of iron or other suitable metal or
material are cast or formed each with a circular inclined plane or helical
rib or surface upon its face. The said circular inclined planes or helical
ribs or surfaces are in all respects similar one to the other, so that when
the said discs or blocks or plates are placed face to face one upon the
other they may. be made to form together a cylindrical body, the most
elevated portion of the said circular inclined plane or helical surface on
one disc or plate or block fitting on to the lowest portion of the circular
inclined plane or helical surface on the other disc or plate or block.
When placed in position one of the said discs or plates or blocks, herein-
after called "the travelling disc," is guided so as to be capable of
receiving a forward and backward motion in the direction of its axis,
but is incapable of rotatory motion, and the other of the said discs or
plates or blocks, herein-after called the rotatory disc, is mounted so as
to be incapable of motion in the direction of its axis, but is capable of
rotatory motion, limited however by preference to less than one com-
plete revolution. The effect of this arrangement is that when motion
is communicated to the said rotatory disc in the proper direction the
circular inclined plane or helical surface upon its face, by moving round
upon the circular inclined plane or helical surface on the travelling
dise will force the said travelling disc forward, thus imparting to the
said travelling dise the required travel and pressure. Springs or other
suitable devices may be used to cause the return of the said travelling
disc to its original position when the rotatory diso is turned in the
opposite direction. The said travelling disc is connected or fixed to
the tool, press plate, valve, or other acting part to which motion and
pressure are to be imparted, and the said rotatory disc may be cast with
or fixed to a spindle, rod, shaft, or other suitable means of commu-
nicating thereto rotatory motion from a key, lever, hand wheel, or other
suitable mover.

If required more than two blocks, plates, or discs may be used so as to
increase the travel. In such cases the intermediate blocks are provided
with circular inclined planes on their upper and lower faces.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Brookes in the Great Seal Patent Office
on the 4th November 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
BROOKES, of 62, Chancery Lane, London, in the County of Middlesex,
Patent and Registration Agent, send greeting..
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourth day of May, in the year of
our Lord One thousand eight hundred and seventy-two, in the thirty-
fifth year of Her reign, did for Herself, Her heirs and successors, give
and grant unto me, the said William Brookes, Her special license, that
I, the said William Brookes, my executors, administrators, and assigns,
or such others as I, the said William Brookes, my executors, adminis-
trators, 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 MEANS FOR
COMMUNICATING MOTION AND PRESSURE TO PARTS OF PRESSES, COCKS, AND VALVES,
VICES, AND JACKS, WHICH IMPROVEMENTS ARE ALSO APPLICABLE IN COMMUNICATING
MOTION AND PRESSURE TO PARTS OF OTHER APPARATUS," a communication to
me from abroad by Luis Alexandre Farjon, of Brussels, in the Kingdom
of Belgium, Engineer, upon the condition (amongst others) that I, the
said William Brookes, 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 William Brookes, do hereby declare
the nature of the said Invention, and in what manner the same is to be

page_text: performed, to be particularly described and ascertained in and by the
following statement thereof, that is to say :-
This Invention, as communicated to me, relates to means for com-
municating motion and pressure to the acting parts of presses, cocks,
valves, jacks, vices, and other apparatus wherein pressure and limited
travel are required; and it consists in the following mode of commu-
nicating motion and pressure to the said parts as a substitute for the
endless screws, levers, cams, or eccentrics generally used for such
purposes.
Two discs or plates or blocks of iron or other suitable metal or
material are cast or formed each with a circular inclined plane or helical
rib or surface upon its face. The said circular inclined planes or helical
ribs or surfaces are in all respects similar one to the other, so that when
the said discs or blocks or plates are placed face to face one upon the
other they may be made to form together a cylindrical body, the most
elevated portion of the said circular inclined plane or helical surface on
one disc or plate or block fitting on to the lowest portion of the circular
inclined plane or helical surface on the other disc or plate or block.
When placed in position one of the said discs or plates or blocks,
herein-after called the "travelling disc," is guided so as to be capable
of receiving a forward and backward motion in the direction of its axis,
but is incapable of rotatory motion, and the other of the said discs or
plates or blocks, herein-after called the rotatory disc, is mounted so as
to be incapable of motion in the direction of its axis, but is capable of
rotatory motion, limited however by preference to less than one complete
revolution. The effect of this arrangement is, that when motion is com-
municated to the said rotatory disc in the proper direction the circular
inclined plane or helical surface upon its face by moving round upon
the circular inclined plane or helical surface on the travelling disc
will force the said travelling disc forward, thus imparting to the said
travelling disc the required travel and pressure. Springs or other
suitable devices may be used to cause the return of the said travelling
disc to its original position when the rotatory disc is turned in the
opposite direction.
The said travelling disc is connected or fixed to the
tool, press plate, valve, or other acting part to which motion and
pressure are to be imparted, and the said rotatory disc may be cast with
or fixed to a spindle, rod, shaft, or other suitable means of communi-
cating thereto rotatory motion from a key, lever, hand wheel, or other
suitable mover.

page_text: If required more than two blocks, plates, or discs may be used so as to
increase the travel. In such cases the intermediate blocks are provided
with circular inclined planes on their upper and lower faces.
Having now described the nature of this Invention I will proceed to
describe the manner in which the same is to be performed, reference
being had to the accompanying Drawing and to the figures and letters
marked thereon.
Figure 1 represents in longitudinal section a cock to which this
Invention is applied. a is the body of the cock; b is a valve for opening
and closing the same; c is the valve spindle, upon the end of which is
formed or fixed the travelling disc or block d, the face of which disc or
block forms a circular inclined plane or helical surface, as shewn by the
lined, e¹; e is the rotatory disc or block, the face of which is also
formed with a circular inclined plane or helical surface e¹, d'; f is a
key for turning the said rotatory disc. When the said rotatory disc e
is turned in the right direction the circular inclined plane or helical
surface e³, d³, upon its face will move round upon the circular inclined
plane or helical surface on the face of the travelling disc d, the point e¹
moving in the direction of e³, and will force down the said travelling disc
and with it the stem or spindle c and valve 6, thereby opening the cock.
When the key or handle f is turned in the opposite direction the
rotatory disc c moves back to its former position, as shewn in the
Drawing, and a spring 7 placed round the valve stem or spindle c closes
the valve b, at the same time pressing back the travelling disc against
the face d¹, e³, of the rotatory disc e.
Figure 2 represents in longitudinal section a large cast-iron cock
the valve of which is actuated according to these improvements. a is
the body of the cock; b, the valve; b, the valve seat upon which tho
valve 6 is pressed down when the cock is closed; is the valve stem
which fits into a suitable hole made to receive it and in which it has
a certain amount of play in the travelling disc or block d; e is the
rotatory disc, to which rotatory motion may be given by means of a
key or lever fitting on the stem e³ of the said disc; is an india-rubber
washer placed round the valve spindle c to allow of the valve ¿
adjusting itself suitably upon its seat. By turning the rotatory diso e
the travelling disc will be forced down, causing the valve 6 to rest
upon its seat b¹ and close the cock. The details of construction of
this cock will be readily understood from the Drawing.

page_text: Figure 2³ shows another form of metallic valve which may be used in
place of the valve b, Figure 2, the valve seat being made to correspond.
•
Figure 3 shows in front elevation the application of this Invention
to a copying press. a is the frame of the press; b, the bottom plate; c,
the pressing plate which is guided by the uprights a', a², of the frame a,
upon which uprights the lugs c', c³, of the pressing plate care capable
of sliding up and down; d, d, are springs on the uprights a', a³, which
springs press the plate cupwards. Upon the said pressing plate c is formed
or fixed the travelling disc f; g is the rotatory disc, the stem g' of which
disc passes upwards through the frame a and has affixed upon its upper
end the hand lever / by which motion is given to the said rotatory disc.
By turning the said hand lever the said rotatory disc g is caused to turn
round and forces down the travelling disc f and press plate c upon
the book or other article which may have been placed between the
bottom plate 6 and the press plate c, communicating thereto the required
pressure.
Figure 3B is a transverse section of the rotatory disc g, Figure 3, and
part of its stem g', and of the travelling disc f with part of the pressing
plate e. Figure 3º is a plan of the same.
Figure 4 represents the application of this Invention to a copying
press similar to the copying press represented by Figure 3, except as
regards the means of communicating motion and pressure to the
pressing plate. The like parts in the two said presses are indicated by
the same letters of reference.
Instead of two discs or blocks provided with circular inclined planes 2
upon their faces being used, as in Figure 3, in the present case a third
intermediate block or disc i provided with circular inclined planes upon
its upper and lower faces is placed between the two discs or blocks f, 9,
which latter blocks or discs are fixed to the frame a and press plate c
respectively. Rotatory motion being given to the said third or inter- 3
mediate block or disc i, the plate c will be forced down upon the block
k placed between the bottom plate b and press plate c, and the travel of
the said press plate will be greater than that of the press plate shown
in Figure 3.
Figure 4 shows the application of this Invention to a stamping press. 3
a is the frame of the press; b, the stamping die; c, is the rotatory disc,
and d the travelling disc. By reference to the Drawing it will be
readily understood that when rotatory motion is communicated to the

page_text: rotatory disc c the travelling disc and stamping die will be forced down
and the stamping effected.
and
Figure 5 represents the application of this Invention to a punching
machine. a is the frame; b, the punch or tool; c, the rotatory disc;
d, the travelling disc.
Figure 6 represents this Invention applied to an iron vice; Figure 6*
is a transverse section of the same; Figure 6' is a longitudinal section
showing the discs separately. The same letters of reference indicate like
parts in Figures 6, 64, and 6º. a, a, are the jaws of the vice; b, the
rotatory disc, and c the travelling disc. Motion is given to the said
rotatory disc 6 by the action of a bar or lever inserted in the head d of
the said disc.
Figure 7 represents part of a cramping frame to which this Invention
is applied. a is the rotatory disc, and 6 the travelling disc. The con-
struction and action of this machine will be readily understood from the
Drawing.
Figure 8 represents a series of three blocks or discs applicable to jacks
and other machines in which increased travel is required for the acting
parts. In this arrangement the intermediate two-faced block c forms
the rotatory disc; the single-faced block a is the travelling block, and the
third block 6 is stationary. When rotatory motion is communicated
in one direction to the two-faced block c, the said block ascends the
circular inclined plane on the block b, and forces upwards the travelling
block a, as shewn in the Drawing. The contrary takes place when the
said block c is turned in the opposite direction. It will be readily
understood from the divers applications of this Invention herein-before
described that the means of communicating motion and pressure
according to this Invention are applicable to other apparatus and
machinery wherein pressure and limited travel are required.
Having now described the nature of this Invention, and means of
carrying the same into practical effect, I wish it to be understood that
I do not confine myself to the precise details herein-before described
and illustrated in the accompanying Drawing, as the same may be
varied without departing from the nature of the Invention; but I claim
5 as of this Invention,―
Firstly. The mode of communicating motion and pressure to the
acting parts of presses, cocks, valves, vices, jacks, and other annaratus.

page_text: wherein pressure and limited travel are required, substantially as herein-
before described and illustrated in the accompanying Drawing, that is
to say, by employing for the purpose a pair of discs or plates or blocks
of iron or other suitable metal or material, cast or formed each with a
circular inclined plane or helical rib or surface upon its face, and placed
one against the other face to face, so that, by turning in the proper
. direction one of the said discs or blocks, herein called the rotatory disc,
upon the other disc or block, herein called the travelling disc, which
latter disc or block is guided so as to be incapable of rotating but can
receive motion in the direction of its axis, the said rotatory disc or block
will force forward the other or travelling disc or block, and the parts
connected therewith, springs or other suitable devices being used to
cause the return of the said travelling disc when the rotatory disc is
moved round in a contrary direction.
Secondly. The mode of increasing the travel of the travelling disc or
block by the use of one or more intermediate discs or blocks, substantially
as herein-before described and illustrated in the accompanying Drawing.
In witness whereof, I, the said William Brookes, have hereunto set
my hand and seal, this Fourth day of November, in the year of
our Lord One thousand eight hundred and seventy-two.
