Year: 1874

page_text: LETTERS PATENT to Edward Waterman, of the City and County of
Bristol, for the Invention of "AN IMPROVED CONSTRUCTION OF PRESS
APPLICABLE TO THE STAMPING OUT OR EMBOSSING OF LEATHER AND TEXTILE
AND OTHER MATERIALS."
Scaled the 7th August 1874, and dated the 21st March 1874.
PROVISIONAL SPECIFICATION left by the said Edward Waterman at
the Office of the Commissioners of Patents, with his Petition, on
the 21st March 1874.
I, EDWARD WATERMAN, of the City and County of Bristol, do hereby
declare the nature of the said Invention for "AN IMPROVED CONSTRUCTION
OF PRESS APPLICABLE TO THE STAMPING OUT OR EMBOSSING OF LEATHER AND TEXTILE
AND OTHER MATERIALS," to be as follows:-
The object of this Invention is to provide a press (for stamping out.
leather and other fabrics by means of loose cutters) which will enable
the workman to have well in view (for the purpose of handling) the.
material on which he is operating, so that he may arrange the cutters.

page_text: thercon to avoid defective places and otherwise economically adapt
their arrangement when cutting leather to the inequalities in the thick-
ness of the skins. This advantage is obtained by causing the platten to
traverse horizontally away from the work as well as vertically to give
the nip.
The horizontal bed of the press is made fast to a pair of standards,
which are fitted on their inner faces with guides for receiving a pair of
vertically sliding checks that carry the platten. Attached to or cast
with the cheeks are slotted arms which project outwards in rear of the
press. These arms are intended to form ways on which the platten may
be run out clear of the bed of the machine.
The platten is fitted with antifriction rollers, and it is connected by
means of a pair of jointed rods to a horizontal rock shaft, which has its
bearings at the top of the end standards.
The sliding checks receive their motion from excentrics on a longi-
tudinal shaft situate below the bed of the press, and by this means the
platten when it is over the bed is brought down to give the nip, and
raised from the work. In rear of this excentric shaft is mounted a shaft.
which carries an excentric for working the rock shaft before mentioned
as imparting the traverse motion to the platten. This second or back
shaft is driven by a pinion, which it carries, gearing into a spur wheel
which is loose on the excentric shaft, but is made fast thereto when
required by a conical clutch. This clutch is set in action by a crank
lever which bears against a cam keyed on the excentric shaft. The
depression of the crank lever by the cam will throw the clutch into
action, and thus the traverse motion of the platten will be properly
timed.
For the purpose of locking the back shaft and relieving the platten of
its action a notched plate is keyed on to the end of the back shaft and
fitted to receive a locking pin carried by a bell crank, which is put in
action by a spring and thrown out of action by a cam on the end of the
excentric shaft.
To fit the press for stamping out a wooden block is placed on the bed
of the press, and upon this the leather or other material to be operated
upon is laid. Detached cutters of the required shape are then disposed
over the material according to the judgment of the workman,, the
platten at that time resting on its guides, which extend in rear of the

page_text: press. When the cutters are properly arranged the press is ready for
starting. This press is by preference worked by steam power, but in
that case it is started by means of a treadle. The driving pulley is
mounted loosely on its shaft, and it is made fast thereto by means of a
sliding clutch. This clutch is operated by the depression of the
treadle..
Rotary motion is communicated from the driving pulley shaft to the
excentric shaft before mentioned by means of spur gearing, and the
action of the press is arrested by means of a cam on the excentric shaft
acting upon a rock lever connected with the treadle levers. When this
rock lever is set in action by the excentric it will, by reason of its
connection with the treadle lever, throw the clutch out of action, and
thereby stop the action of the press.
Twill be chriane that this

SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Edward Waterman in the Great Seal Patent Office
on the 21st September 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
WATERMAN, of the City and County of Bristol, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-first day of March, in the year
of our Lord One thousand eight hundred and seventy-four, in the
thirty-seventh year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Edward Waterman, Her special
licence that I, the said Edward Waterman, my executors, administrators,
and assigns, or such others as I, the said Edward Waterman, 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
AN IMPROVED CONSTRUCTION OF PRESS APPLICABLE TO THE STAMPING OUT OR
EMBOSSING OF LEATHER, TEXTILE AND OTHER MATERIALS," upon the con-.
6.6

page_text: dition (amongst others) that I, the said Edward Waterman, 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 imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Edward Waterman, 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, reference being had to the Drawings
hereunto annexed, and to the letters and figures marked thereon (that
is to say) :-
The object of this Invention is to provide a press (for stamping out
leather and other fabrics by means of loose cutters) which will enable
the workman to have well in view (for the purpose of handling) the
material on which he is operating, so that he may arrange the cutters
thercon to avoid defective places and otherwise economically adapt their
arrangement, when cutting leather, to the irregularities in the thickness
of the skins. This advantage is obtained by causing the platten to
traverse horizontally away from the work as well as vertically to give
the nip.
In the accompanying Drawings Fig. 1 is a front elevation of the
press; Fig. 2 is an end elevation of the right-hand side of Fig. 1; and
Fig. 3 is a sectional clevation taken through the platten in the line 1, 2,
of Fig. 1.
A is the horizontal bed of the press made fast to a pair of standards B, B.
These standards are fitted on their inner faces with guides for receiving
a pair of vertically sliding cheeks C, C, that carry the platten. Attached
to or cast with the cheeks are slotted horizontal arms C₁, C, which
project outwards in rear of the press. These arms are intended to form
ways on which the platten D may be run out clear of the bed of the
machine.
•
The platten D is fitted with antifriction rollers d, and also with a pair
of bracket arms d', which are connected by means of a pair of jointed
rods d² to a horizontal rock shaft E, which has its bearings at the top of
the end standards.

page_text: The sliding cheeks receive their motion from a pair of excentrics c on
a longitudinal shaft F situate below the bed of the
press.
By
In order to adapt the platten to various thicknesses of work the
cheeks C which carry the platten require to be adjusted vertically with
respect to the excentrics c. To this end instead of connecting the
excentric rods c¹ directly with the cheeks C they are jointed to vertical
adjusting screws c² which pass up through guide boxes C² carried by the
cheeks. Fitted to these screw boxes are bevil pinions c³, the hubs of
which are tapped to allow of their working freely on the screws c².
turning these pinions the cheeks Ċ will be raised or lowered, and with
them the platten. To ensure a corresponding adjustment of the two
cheeks they are each furnished with a bracket arm c', in which is
mounted a transverse shaft c* for carrying a pair of bevil pinions in gear
with the pinions c³. Keyed to the shaft c³ is a hand wheel c', by turning
which rotary motion is simultaneously imparted to the pinions c³, and
thus both cheeks are raised or lowered to the like extent.
It will now
be understood that by the rotation of the excentrics c the platten, when
it is over the bed, will be brought down to give the nip, and will then
be raised clear of the work.
In rear of the excentric shaft F is mounted a shaft G, which carries
an excentric e for working through the excentric rod e', and arm e³, the
rock shaft E before mentioned as imparting the traverse motion to the
platten. This shaft G is driven by a pinion g which it carries, gearing
into a spur wheel f, which is loose on the shaft F, but is made fast
thereto when required by a conical clutch f¹ in connection therewith.
This clutch is set in action by a crank lever H mounted on a short
standard H. A bowle on one arm of this crank lever bears against a
cam H keyed on the shaft F. The depression of the crank lever by the
rotating cam will cause the forked end of the lever H to throw the clutchi
into action, and thus the traverse motion of the platten will be properly
timed.
For the purpose of locking the shaft G and relieving the platten of its
action a notched plate g¹ is keyed on to the end of the shaft G and fitted
to receive a locking pin 9². This pin is carried by a bell-crank lever g³
supported on a standard G', and it is put in action by a spring 9* and
thrown out of action by a cam g5 on the end of the excentric shaft F.
To fit the press for stamping out, a wooden block A¹ is placed on the
bed of the press, and upon this the leather or other material to be

page_text: operated upon is laid. Detached cutters of the required shape are then
disposed over the material, according to the judgment of the workman,
the platten at that time resting on its guides, which extend in rear of
the press. When the cutters are properly arranged the press is ready
for starting. This press is by preference worked by steam power, but
in that case it is started by means of a treadle. I is the driving pulley
mounted loosely on its shaft I', and it is made fast thereto by means of
a sliding clutch I which is operated by the depression of the treadle I³,
as will be presently more particularly described.
pulley shaft to the
Rotary motion is communicated from the driving
excentric shaft F by means of the spur gearing i, i. The action of the
press is arrested by means of a cam 2 (see Fig. 3) on the excentric
shaft F in the following manner :-³ is a rock lever mounted loosely on
the shaft I¹ and carrying at its free end a bowle that bears upon the
cam 3. This rock lever is connected by a coupling rod to a rock lever ¿ª
having its fulcrum on a bracket at the foot of the machine. A spring
under this rock lever serves to keep the bowle of the lever & in contact
with the cam 2. Overlying the lever is the tail of a bell-crank
lever I', the upper and forked end of which embraces the sleeve shaft or
boss of the clutch I². So long as the larger radius of the cam bears
upon the bowle of the lever the clutch will be maintained in action,
but when the recess in the cam comes round the crank lever I will be
released from the pressure of the lever i, and the clutch will slip out of
action. The pinion i of the clutch is made broad enough to allow of
this lateral motion without sliding out of gear with the spur wheel on
the shaft F. Underlying the lever I' is the treadle lever I, the nose
of which (when the treadle lever is depressed) will tip the bell-crank
lever I and throw the clutch into action, motion will therefore be then
imparted to the press.
It will be obvious that this press may be employed for embossing and
impressing by the adaptation of suitable appliances thereto.
Having now set forth the nature of my Invention of "An Improved
Construction of Press applicable to the Stamping out or Embossing of
Leather, Textile and other Materials," and explained the manner of
carrying the same into effect, I wish it to be understood that under the
above in part recited Letters Patent I claim, the arrangement of
stamping or embossing press above described furnished with a platten

page_text: which receives a traverse motion to and from the work, in the manner
nd for the purpose above set forth.
In witness whereof, I, the said Edward Waterman, have hereunto
set my hand and seal, the Eighteenth day of September, in
the year of our Lord One thousand eight hundred and seventy-
four.
