IMPROVEMENTS IN PRESSES FOR CUTTING AND EMBOSSING VARIOUS SUBSTANCES
Year: 1872

page_text: LETTERS PATENT to Frank Holloway, of New Cross, in the County
of Kent, Engineer, for the Invention of "IMPROVEMENTS IN PRESSES
FOR CUTTING AND EMBOSSING VARIOUS SUBSTANCES."
Sealed the 19th November 1872, and dated the 22nd May 1872.
PROVISIONAL SPECIFICATION left by the said Frank Holloway at the
Office of the Commissioners of Patents, with his Petition, on the
22nd May 1872.
I, FRANK HOLLOWAY, of New Cross, in the County of Kent, Engineer,
3 do hereby declare the nature of the said Invention for “IMPROVEMENTS
IN PRESSES FOR CUTTING AND EMBOSSING VARIOUS SUBSTANCES," to be as
follows:-
My improved press for cutting and embossing various substances
relates to that class of press in which a follower attached to a vertical
rod which works in guides is brought down onto a cutting or embossing
tool. This is effected by means of a lever or levers mounted on a fulcrum
or pivot in the side standards. This lever is provided at its other end
with a bowle or antifriction roller, which is capable of adjustment in a

page_text: slot to correspond either to the intended length of stroke of the follower
or to the thickness of the substance to be operated upon. The lever is
actuated by a cam, which bears against the surface of the antifriction
roller or bowle. On the axle of this cam is keyed a toothed wheel, into
which gears a snail or screw, whereby a slow motion is communicated
to it. The spindle of this snail or screw carries a winch handle or hand
wheel, whereby it is rotated when required. The under side of the snail
or worm rotates in an oil trough, so that it should be kept constantly
lubricated.
For embossing purposes part of the circumference of the cam should
be made concentric, so as to produce a dwell when the pressure is given.
This is not so important when the machine is used only for cutting.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Frank Holloway in the Great Seal Patent Office on
the 22nd November 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FRANK
HOLLOWAY, of New Cross, in the County of Kent, Engineer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-second 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 Frank Holloway, Her special licence that I,
the said Frank Holloway, my executors, administrators, and assigns, or
such others as I, the said Frank Holloway, 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 PRESSES FOR CUTTING AND
EMBOSSING VARIOUS SUBSTANCES," upon the condition (amongst others) that
I, the said Frank Holloway, my executors or administrators, by an instru-

page_text: ment 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 Frank Holloway, 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 Drawing hereunto
annexed, and to the letters and figures marked thereon (that is to say):-
My improved press for cutting and embossing various substances
relates to that class of press in which a follower attached to a vertical
rod which works in guides is brought down onto a cutting or embossing
tool, and is made to cut, punch, emboss, or press, according to the nature
of the tool that is used and the operation it is intended to effect.
In the accompanying Drawing Fig. 1 is a side elevation of one of my
improved presses; Fig. 2 is a plan or top view of the same; Fig. 3 is an
end view, some of the parts being removed; Fig. 4 is a side elevation of
a press, in which the adjustments are somewhat different from the plan
shewn in Fig. 1.
The desired operation, whether it be cutting, punching, embossing, or
pressing, is effected by means of a lever a mounted on a fulcrum or
pivot a¹ in the side standards b, b. This lever a is provided at one end
with a bowle or antifriction roller c, which is capable of adjustment in a
slot c', as shewn at Fig. 4, so that its throw may correspond either to the
intended length of stroke of the follower or to the thickness of the
substance to be operated upon.
In Fig. 1 an adjustment equivalent to this and with the same object
is shewn as adapted to the follower, and will be hereafter more parti-
cularly explained. The lever a is actuated by a cam d (shewn by dots
at Figures 1 and 4), which bears against the surface of the antifriction
roller or bowle c. On the axle of this cam d is keyed a toothed wheel d',
into which gears a snail or screw f, whereby a slow motion is commu-
nicated to it. The spindle of this snail or screw carries a winch handle
or hand wheel f¹, whereby it is rotated when required. The under side

page_text: of the snail or worm frotates in an oil trough e (shewn by dots in
Figures 1 and 3), so that it will be kept constantly lubricated.
The upper end of the lever a (in Figures 1 and 2) is made in the form
of a fork (as indicated by dots in the plan view, Fig. 2), so as to embrace
the stem g¹ attached to the follower h; the stem glis provided with
two collars g, g, between which the forked end of the lever a works.
At the upper end of the stem g¹is a brass hand wheel or disc g², whereby
the stem g¹ may be turned round when required. The lower part of the
stem has a screw thread cut upon it and screws into a female screw
tapped in the follower h, the stem of which is capable of moving up and
down in the vertical guide i.
It will now be understood that the follower may be raised or lowered
in its guide i by merely turning the stem g¹ in the required direction by
means of the brass handle g³, so that the lower face of the follower may
be adjusted with great nicety.
In Fig. 4 the follower is mounted in a guide i in the same manner
as in Figures 1 and 2, but the mode of adjusting the position of the
follower is different. In Fig. 4 the upper end of the lever a is simply
inserted in a slot made at the upper end of the stem of the follower.
The adjusting device is at the opposite end, which carries a slotted
frame a³. The bearings of the antifriction bowle c are placed in the slot
of the frame a³, and are adjusted at any point therein by means of the
regulating screw j, as by turning this screw in either direction the lever a
will be rocked on its centre of motion, and the working surface of the
follower will be adjusted to a nicety, according to the nature of the work
to be done.
In pressing or embossing it is preferred to bring down the follower
onto the back of the embossing plate, which is placed on the work; but
for cutting or punching it will sometimes be found more convenient to
fix the working tool or punch in the follower either by screwing it in
or otherwise.
For embossing and pressing purposes part of the circumference of the
cam should be made concentric with the axis, as shewn in the Drawing at
Fig. 4, so as to produce a dwell when the pressure is given. This is not
so important when the machine is used only for cutting or punching (as
in the arrangement shewn at Figures 1 and 2).

page_text: For punching or cutting purposes the cam may be made to act more
quickly than in Fig. 4, and it may be made to act two, three, or more
times for each rotation of the cam or wheel d, as shewn at Figures
1 and 2. When the press has done its duty the follower is brought
back to its original position by a spring or other equivalent device,
which may be adapted to the tail end of the lever a, but is not shewn
in the Drawing.
Having now described my Invention of "Improvements in Presses for
Cutting and Embossing various Substances," and having explained the
manner of carrying the same into effect, I claim as the Invention
secured to me by Letters Patent as aforesaid, working the follower of
a cutting, punching, pressing, or embossing machine by means of a
lever actuated by a cam, and provided with an antifriction bowle and
fine adjustment, as herein set forth.
In witness whereof, I, the said Frank Holloway, have hereunto set
my hand and seal, the Twenty-second day of November, in the
year of our Lord One thousand eight hundred and seventy-two.
FRANK HOLLOWAY. (L.S.)
