CERTAIN IMPROVED MACHINERY FOR MAKING ENVELOPES AND BAGS
Year: 1852

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
SHAW, of Birmingham, in the County of Warwick, Patent Agent, send
greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Seventeenth day of
December (One thousand eight hundred and fifty-two), in the sixteenth year
of Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said George Shaw, my exors, adiñors, and assigns, Her especial
licence, full power, sole. privilege and authority, that I, the said George
Shaw, my exors, adñors, and assigns, or such others as I, the said George
Shaw, my exors, adiñors, or assigns, should at any time agree with, and
no others, from time to time and at all times during the term of years
therein expressed, should and lawfully might make, use, exercise, and vend,
within England, Wales; and the Town of Berwick-upon-Tweed, the Invention
of "CERTAIN IMPROVED MACHINERY FOR MAKING ENVELOPES AND BAGS," com-
municated to me from abroad; in which said Letters Patent is contained a
proviso that I, the said George Shaw, should cause a particular description or

page_text: the nature of the said Invention, and in what manner the same is to be
performed, by an instrument in writing under my hand and seal, to be
inrolled in Her said Majesty's High Court of Chancery within six calendar
months next and immediately after the date of the said in part recited
Letters Patent, as in and by the same, reference being thereunto had, will
more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
George Shaw, do hereby declare that the nature of the said Invention, and
the manner in which the same is to be performed, are fully described and
ascertained in and by the following statement thereof, reference being had
to the Drawing hereunto annexed, and to the figures and letters marked
thereon, that is to say :-
The Invention relates,-
First, to the application of adhesive material to the carrying instruments
used to feed paper blanks into envelope or bag folding and creasing machines,
and also into other machinery used in the production of envelopes or paper
bags.
Secondly, the Invention relates to means for creasing the blanks for folding
into envelopes or bags.
In order that the Invention communicated to me may be fully understood,
I will proceed to explain the means pursued by me.
DESCRIPTION OF THE DRAWING.
I have not thought it necessary to shew complete machines for feeding and
folding paper to produce envelopes or bags, as, amongst others, the various
movements for effecting the feeding from a pile of blanks of individual
blanks by moving instruments, which take such single blanks and place
them on to a folding table, was described in a Specification of a Patent
granted to Amedée Francois Rémond on the Twenty-eighth day of February,
in the year One thousand eight hundred and forty-nine, I have therefore
only thought it necessary to show the separate parts to which the present
improvements apply.
Figure 1 shows the under side of the instrument (somewhat different in
form to that described in such former Specification, but which is to have
like movement given to it) for receiving a blank from the pile of blanks; and
by the adhesive matter of carrying such single blanks to creasing or folding
means, or it may be to gumming or drying means; and the improvement
consists in the application thereto of the adhesive matter as a holding means,

page_text: and which I will now explain. I take pieces of india-rubber, and immerse
the same in turpentine, to which I set light and burn until the india-rubber
is partially melted. I then wipe the surface of such india-rubber between
paper, to take off the outer and more liquid surface until the paper although
still tending to adhere comes away clean. India-rubber thus prepared and
made adhesive, I apply as may be found desirable to the transferring instru-
ment. I have found it sufficient to apply the same at the parts a, a, a, but
do not confine myself thereto; and I fix such prepared india-rubber by merely
pressing the india-rubber against the parts, or by the application of pins or
otherwise.
The second part of the Invention consists in the application of a suitable
shaped plunger, with comparatively sharp edges, in combination with flexible
rotating surfaces for creasing the folding parts of envelopes or bags.
Figure 2 shews a section of these parts sufficient for this part of the In-
vention to be understood. Figure 3 shows a plan of the flexible surfaces,
which consist of prepared or vulcanized india-rubber, in the form of tubes a,
upon axes b, capable of revolving in bearings c. d, is the plunger, which I
prefer to be somewhat larger than the quadrangular space left between the
cylindrical surfaces a, so that when the blank is placed over the space formed
by the surfaces a, by the feeder, Figure 1 (or other suitable feeder), and the
plunger & descends, the comparatively sharp edges of the plunger will cause
the blank to be creased by pressing into the flexible surfaces of the cylinders a.
The paper thus creased by passing through the space between the surfaces a, a,
will be received into a suitable receiver below.
Having thus described the nature of the said Invention, I would have it
understood that I do not confine myself to the precise details, so long as
the peculiar character of either part of the Invention be retained; but what
I claim is the preparation of adhesive material, and the application thereof
to the feeding or transferring means used in the manufacture of envelopes
and paper bags, as herein explained.
Secondly, I claim the application of flexible creasing means of a cylindrical
form in combination with a suitably formed plunger, as herein explained, in the
manufacture of envelopes and paper bags.
In witness whereof, I, the said George Shaw, have hereunto set my
hand and seal, this Fifteenth day of June, in the year of our Lord
One thousand eight hundred and fifty-three.
GEORGE SHAW. (LS.)

page_text: AND BE IT REMEMBERED, that on the Fifteenth day of June, in the
year of our Lord 1853, the aforesaid George Shaw came before our said
Lady the Queen in Her Chancery, and acknowledged the Specification afore-
said, and all and every thing therein contained and specified, in form above
written. And also the Specification aforesaid was stamped according to the
tenor of the Statute made for that purpose.
Enrolled the Seventeenth day of June, in the year of our. Lord One
