IMPROVEMENTS IN PRODUCING CORRUGATED SURFACES ON LEATHER
Year: 1851

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
PEGG, of Leicester, Manufacturer, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Twenty-ninth day of May, in the fourteenth year of Her
reign, and in the year of our Lord One thousand eight hundred and fifty-one,
did, for Herself, IIer heirs and successors, give and grant unto me, the said
John Pegg, Her especial licence, full power, sole privilege and authority, that
I, the said John Pegg, my exors, adñiors, or assigns, or such others as I, the
said John Pegg, my exors, adññiors, 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, my
Invention of "IMPROVEMENTS IN PRODUCING CORRUGATED SURFACES ON LEATHER;"
and in which said Letters Patent is contained a proviso that I, the said
John Pegg, shall cause a particular description of the nature of my said
Invention, and in what manner the same is to be performed, to be enrolled
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.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
John Pegg, do hereby declare that the nature of my said Invention, and the
manner in which the same is to be performed, are fully described and ascer-
tained in and by the following statement thereof, reference being had to the
Drawings hereunto annexed, and to the figures and letters marked thereon,
that is to say:--
My Invention consists of employing strands or bands of india-rubber in com-
bination with leather, by the use of grooved or fluted rollers, or crimping
surfaces or apparatus, so as to corrugate the leather according to the crimping
surfaces or apparatus, and to obtain to such corrugated surfaces elasticity by
means of the india-rubber. And in order that my Invention may be most fully
understood and readily carried into effect, I will proceed to describe the means
pursued by me. The india-rubber which I prefer to employ is that which has
undergone a process to render it permanently elastic; and I use that descrip-
tion which is called vulcanized india-rubber; and I cause strands or threads
thereof to be held distended in a suitable frame or apparatus, according to the
nature of the work to be performed; and I apply india-rubber cement to one
side of a piece of leather, and place the leather in contact with the stretched
strands or bands of india-rubber; and I use a second piece of leather, or it
may be of woven fabric, coated with india-rubber cement against the first
mentioned piece of leather, by which the strands or bands of india-rubber will
be shut in between the two surfaces of the leather, or one surface of leather,
and one of woven fabric. The two surfaces so placed together are then sub-
mitted to pressure between rollers which causes them to adhere more firmly.
The leather is then to undergo the corrugating or crimping process; and in
doing this I cause the leather to be slightly damped and passed through or
between a crimping apparatus, which may be heated or otherwise, so as to
produce permanent corrugations in the leather; and after leaving the crimping
apparatus, the leather is put into warm water, about seventy degrees of Fahren-
heit, more or less, by which means euamelled and stiff or stubborn leathers
become softened to such an extent as to allow the strands or threads of india-
rubber to contract freely, the leather at the same time partaking of such
contraction. The fabric is then taken out and dried.
DESCRIPTION OF THE DRAWING.
Figure 1 shows a frame with several strands of india-rubber held distended
therein. Figure 2 is a section thereof, the red lines indicating a piece of
leather coated on the under side with india-rubber cement: and the vellow

page_text: line indicates another piece of leather, or it may be a piece of woven fabric; also
coated with india-rubber cement, which may be used either in a moist or dry
state, by which it will be evident that the elastic india-rubber will be closed
between the two surfaces, and when the cement is set or dry, if used moist,
the same may be removed from the frame and then corrugated as above
mentioned. This arrangement is for cases where the india-rubber is only to
be introduced, intermediate of the length of the piece of leather as shewn by
the plan and edge view, Figure 3.; but it will be evident that in such manner
considerable lengths of leather may have india-rubber applied thereto.
Figure 4 shews a pair of rollers, such as are employed when corrugating-a
piece of elasticated leather, such as Figure 3, and the result produced is indi-
cated at Figure 5; but in case considerable lengths of leather be treated
according to my Invention then I use rollers, such as are shewn at Figure 6;
other forms of crimping apparatus may be used, but the plan which I prefer
is as above described.
Having thus described the nature of my Invention and the manner of per-
forming the same, I would have it understood that I do not confine myself to
the details as herein described, so long as the peculiar character of the Inven-
tion be retained; but what I claim is the employment of strands or bands of
india-rubber, in combination with leather, by means of grooved or fluted
rollers or crimping apparatus, so as to corrugate the leather, as hercin
described.
In witness whereof, I, the said John Pegg, have hereunto set my hand
and seal, this Seventeenth day of November, in the year of our Lord
One thousand eight hundred and fifty-one.
Signed, sealed, and delivered, by tho
within-named John Pegg, in the
presence of
JOHN (LS.) PEGG.
