County of Middlesex for an Invention of IMPROVEMENTS IN MACHINERY OR
APPARATUS FOR MAKING PAPER BAGS Communicated to him from abroad

Office of the Commissioners of Patents on the 3rd October 1882.

WILLIAM LLOYD WISE, of 46 Lincoln's Inn Fields in the County of Middlesex
"IMPROVEMENTS IN MACHINERY OR APPARATUS FOR MAKING PAPER BAGS
(a communication to me from abroad by Myron Nathaniel Stanley of New York,
State of New York one of the United States of America)
This invention relates to the application, to machines for making paper bags
from a continuous band, of folding apparatus for making two or more additional
lateral folds in the continuous band of paper, before it enters the machine, in such
a manner as to obtain bags shaped like a pair of bellows with square or rectangular
bottoms when opened.
This folding apparatus is applicable to the machine described in the provisional
specification dated 4 May 1882, Nº 2098, as well as to other machines for making
paper bags from a continuous paper band, and may be attached and detached at
will. In the latter case the machine produces flat bags of the ordinary pattern.
The apparatus is composed of two plates connected to two supports by means of
screws. On each of the two plates there is screwed a guide in such a manner as to
form two grooves in each of which there is situated a counter-plate held by a
support to which it is connected by means of thumb screws
The apparatus works in the following manner :-
The paper is introduced by hand between the plates and the counter-plates at
their pointed extremity, and the folds, once commenced, continue to be formed by
the movement of the continuous band.

page_text: The rest of the operation takes place in a manner which varies according to the
kind of machine to which the folder is applied. By the use of this apparatus the
bags, instead of being finished side-wise as is usually the case, by a back-bone
resulting from the two opposed and flattened sides of the bag, have folds like a
pair of bellows, which render the bags more convenient, inasmuch as they have a
square or rectangular form, when once the folds are opened.
The screws and other appliances for fixing the apparatus are inserted in oval
holes; thus all the different parts may be adjusted in such a way as to vary the
size of the bags and the dimensions of the folds.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said William Lloyd Wise in the Great Seal Patent Office on the
31st March 1883.

"IMPROVEMENTS IN MACHINERY OR APPARATUS FOR MAKING PAPER BAGS,"
(a communication to me from abroad by Myron Nathaniel Stanley of New York,
State of New York, one of the United States of America)
This invention relates to the application to machines for making paper bags
from a continuous band, of folding apparatus for making two or more additional
lateral folds in the continuous band of paper before it enters the machine, in
such a manner as to obtain bags shaped like a pair of bellows with square or
rectangular bottoms when opened. This folding apparatus is applicable to the
machino described in the specification of Letters Patent dated 4 May 1882,
N° 2098, as well as to other machines for making paper bags from a continuous
paper band, and may be attached and detached at will. In the latter caso the
machine produces flat bags of the ordinary pattern.
The accompanying drawing illustrates apparatus according to this invention;
Fig. 1 being an inverted plan, and Fig. 2 an end view.
The apparatus is composed of two plates a a¹ connected to two supports & d¹ by
means of screws m. On each of these two plates there is screwed a guide c, c¹ in
such a manner as to form two grooves, in each of which there is situated a counter
plate b b held by a support ce' to which it is connected by means of thumb
screws P, p¹.
The apparatus works in the following manner :-
The paper (which is shewn by the dotted line a) is introduced by hand between
the plates a a¹ and counter plates b, b¹ at their narrower extremities, and the folds,
once commenced, continue to be formed by the movement of the continuous band.
The rest of the operation takes place in a manner which varies according to the
kind of machine to which the folder is applied. By the use of this apparatus the
bags, instead of being finished sidewise as is usually the case, by a backbone

page_text: resulting from the two opposed and flattened sides of the bag, have folds like a
pair of bellows, which render the bags more convenient, inasmuch as they have a
square or rectangular form, when once the folds are opened.
The screws m n and other appliances for fixing the apparatus are inserted in
oval holes as shewn: thus all the different parts may be adjusted in such a way as
to vary the size of the bags and the dimensions of the folds.
Having described the nature of the said invention and the manner of carrying
the same into practical effect as communicated to me as aforesaid, what I consider
to be novel and original and therefore claim as secured to me under the herein-
before in part recited Letters Patent is :-
In a machine for making paper bags from a continuous band the use of the
improved folding apparatus substantially as hereinabove described with reference
to the accompanying drawings for the purpose specified.
In Witness whereof I the said William Lloyd Wise have hereunto set my
hand and seal this thirty-first day of March in the year of our Lord one
thousand eight hundred and eighty three.
