Office," No. 8, Southampton Buildings, London, Doctor of Laws, for
the Invention of "IMPROVEMENTS IN THE MANUFACTURE OF PAPER BAGS."
-A communication from abroad by Edwin J. Howlett and John P.
Onderdonk, both of Philadelphia, Pennsylvania, United States of
America.
COMPLETE SPECIFICATION filed by the said George Haseltine at the
Office of the Commissioners of Patents, with his Petition and
Declaration, on the 5th May 1873, pursuant to the 9th Section
of the Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
HASELTINE, of the "International Patent Office," No. 8, Southampton
Buildings, London, Doctor of Laws, send greeting.
WHEREAS I am in possession of an Invention for "IMPROVEMENTS
THAN DADZ Bage" and have netitioned Her Majesty to

page_text: grant unto me, my executors, administrators, and assigns, Her Royal
Letters Patent for the same, and have made solemn Declaration that it
has been communicated to me from abroad by Edwin J. Howlett and
John P. Onderdonk, both of Philadelphia, Pennsylvania, United States
of America.
NOW KNOW YE, that I, the said George Haseltine, do hereby declare
that the following Complete Specification, under my hand and seal, fully
describes and ascertains the nature of the said Invention, and in what
manner the same is to be performed, in and by the following statement,
reference being had to the accompanying Drawing forming a part of
this Specification :-
This Invention relates to improvements in the manufacture of that class
of paper bags known as “satchell bottomed" bags, that is to say, bags with
rectangular bottoms; and it consists in folding and cementing a strip of
paper into tubular shape as herein-after described, cutting from the
tube so formed a section of suitable length in such a manner as to leave
a flap turning down the end of the tube adjacent to the flap, and
cementing the said end to the outside of the bag to form a bottom,
which when the bag thus formed is opened or filled shall assume a
rectangular shape. The Drawing shews the bag in different stages of
manufacture.
Figure 1 is a perspective view illustrating the said Invention; Figure 2,
a plan; and Figure 3 is a side view of the same; Figure 4 is another
plan; Figure 5 represents the complete bag expanded;. Figure 6, the
inside of the bottom; and Figure 7, the outside of the bottom thereof.
To describe these improvements more particularly a strip of paper or
the end of a long strip thereof is taken and folded, as shewn in Figure 1,
the edges being lapped and the sides bent inward to form the longitudinal
folds a. The lapped edges having been pasted together, three sides of
the tube thus formed are cut in the line (or plane) b, c, and the fourth
side in the line d, e, tearing or cutting off the waste end, the left hand
end in Figure 1 on the lines b, d, and c, e, Figure 2, which leaves a
projecting flap or end f, Figures 2 and 3. The tube is preferably flattened
before cutting. Then a section of sufficient length to form the bag is cut
from the tube in the manner just described, the three upper sides pro-
jecting beyond the lower side, as seen at the right hand end of Figure 1,
so as to leave a flap for the next bag; the left hand end of the severed

page_text: section is then folded down on the line g, h, and pasted to the outside of
the bag, as shown in Figure 4.
The shape of the opened or filled bag thus made is shown in Figure 5,
the inside of the bottom in Figure 6, and the outside of the bottom in
Figure 7.
The above described operations may be performed either by hand or
machinery; the order in which they are performed may be varied
according to convenience. When the bag is made by machinery guide
fingers or other devices for turning the paper inward to make the folds
should be attached to the ordinary machine for making tubular bags.
Having thus fully described the said Invention as communicated to
me by my foreign correspondents, and the manner of performing the
same, I wish it understood that I claim, a satchel bottomed paper bag
made with two longitudinal folds a, a flap fand a single lateral fold
extending from 9 to h, and cemented to the outside of the bag to form
the bottom thereof, as herein described.
In witness whereof, I, the said George Haseltine, have hereunto
set
my hand and seal, this Fifth day of May, in the year of our
Lord One thousand eight hundred and seventy-three.
Witness,
JAMES EDWARDS,
8, Southampton Buildings,
London.
