I JOSEPH TAYLOR CRAW of Jersey City in the County of Hudson and State of
New Jersey, United States of America Paper Box Maker, do hereby declare the nature
of this invention to be as follows:-
This invention relates to the manufacture of paper boxes, and especially to that
class of boxes commonly known as "siftless knock down boxes," the main objects of
the invention being to provide a box which may be quickly set up, and which when
set up will have a perfectly flat springless bottom without exposed folds, the blank from
which the box is made being so cut and scored, that when the parts are adjusted to
place they will be, as it were, locked against displacement, and that, too, without the
aid of paste or other viscid material except upon the main paste-flap.
To the ends named, the invention consists of a box made from a blank that is cut
and scored to form the sides, ends, paste-flap, double bottom, and rectangular end-
flaps of the box, as will be hereinafter described.
Reference is to be had to the accompanying drawings forming a part of this
specification in which similar figures of reference indicate corresponding parts in all
the views.
Figure 1 is a view of the blank from which my box is formed, the blank being so
cut that when folded it will constitute a box having my preferred form of top or
cover.
Figure 2 is a perspective view of the partially completed box, the inner bottom-flap
being represented partially folded to place, while the main bottom and the end flaps
are represented as they appear prior to being moved to place.
Figure 3 is a perspective view of the box, wherein the parts of one side and end of
the box are broken away, the several parts of the blank being represented as they
appear when folded to complete the bottom of the box, the top of the box being
represented as it appears prior to the closing of the box.
Figure 4 is a longitudinal sectional elevation of the box.
Figure 5 is a cross-sectional elevation of the same.

page_text: Figure 6 is a longitudinal sectional elevation of a modified construction, the different
folds being given to the blank to form the bottom, while the top is represented as
being formed with tucks.
Figure 7 is a cross-sectional elevation of a box constructed and folded as represented
in Figure 6, the top, however, being represented as it appears when open.
Figure 8 is a plan view of the form of box illustrated in Figures 6 and 7.
Figure 9 is a perspective view of a modified form of box; and
Figure 10 is a perspective view of a box wherein the cover is made separate from
the main body of the box but from a blank that is the same except as to size.
In making such a box as the one illustrated in the drawings above referred to, I
take a rectangular blank and score it longitudinally at 11 and 12 and transversely at
13, 14, 15, and 16, cutting the blank at 17 and 18 upon the line of the score 12, and
at 19 and 20 upon the line of the score 13; also cutting the blank from point of the
intersection of the scores 11 and 13 diagonally to the edge of the blank at the end of
the score 14, and diagonally from the intersection of the scores 11 and 16 to the edge
of the blank at the end of score 15..
In the blank so formed, 20 and 21 become the sides of the box ; 22 and 23, the
ends; 24, one thickness of the bottom, and in my preferred manner of folding, the
inner thickness of said bottom, while 25 forms the other thickness of the bottom,
preferably the outer thickness; 26 and 27, the end-flaps ; 28, the main paste-flap ;
29 and 30, the double top, and 31 and 32 the top-folds.
In forming a box from the blank illustrated in Figure 1 and described as above,
the blank is first bent upon the score 14, the paste-flap 28 being bent over so as to be
borne upon by the side 20. The bottom portion 24, is then bent in and pressed
against the side 20, and the flaps 26 and 27 folded upon the bottom portion 25. Said
bottom portion is folded down until the lower opening of the box is closed. The
flaps 26 and 27 are then pressed out against the inner faces of the ends 22 and 23,
and the portion 24 is pressed down between the flaps 26 and 27 and against the upper
face of the outer bottom, 25. This is my preferred manner of folding the box, and in
practice the bottom formed as described will be found to be perfectly flat and at the
same time very secure; but if deemed advisable, lines of paste may be applied to
the outer faces of the flaps 26 and 27, so that said flaps will adhere to the inner faces
of the ends 22 and 23. This pasting, however, will he found to be entirely unnecessary
and superfluous except when exceedingly fine material is to be packed within the box.
Boxes having bottoms formed as above described, may be placed so as to stand in a
vertical position upon the pan or platform of any of the ordinary forms of automatic
scales, and being so placed will receive their charge or load from the scales without
tilting one of the most serious objections of the ordinary form of knockdown box
being that the numerous tucks and folds caused by the adjustment of the parts produce
a bulging, springy bottom, which prevents the boxes from standing in a steady vertical
-position.
After the boxes have been filled, their open ends are closed by folding in the folds
31 and 32 upon the line of scores 33 and 34, which scores are drawn inward to
intersect the angles formed by the meeting of the scores 11 and 14, and 11 and 15.
After the folds 31 and 32 have been adjusted, as described, the outer top-flap, 29, is
folded down and pasted to the upper surface of the inner top-flap, 30, and in this
manner I form my preferred style of box; but in certain cases it might be deemed
advisable to substitute cuts for the scores 33 and 34, such a construction being
represented in figures 6 and 7, and by so cutting the blank I form end-tucks 35, that
are integral with the top portion, 30, and in this top portion, 30, I form transverse
cuts 36.
In folding the box described, the top portion, 29, is folded down to close he top of
the box, the tucks 35 are folded down so as to extend at right angles from the top
portion, 30, which portion is then folded down, the tucks 35 passing inward between
the ends 20 and 23 and the ends of the top portion, 29, after which the locking
flaps 37 are bent over and their apices inserted within the transverse cuts 36 of the
top portion, 30, thus forming a box that will be practically siftless.

page_text: Instead of folding the bottom portion, 24, within the body of the box before intro-
ducing the end-flaps, 26 and 27, such end-flaps may be first folded upon the bottom
portion, 25, the portion 25 then folded over, and the ond-flaps folded out against the
inner faces of the ends 22 and 23, after which the bottom-flap, 24, may be folded
down and pasted to the outer face of the bottom-flap, 25.
A box constructed as described will be found to possess sufficient strength and
rigidity to resist the test of a diagonal strain-that is, to resist the test of a strain
applied diagonally to its corners.
If desired, the end-flap, 27, may be cut off in a line with the score 16, as represented
in Figure 1; but this cutting is not absolutely necessary.
In Figure 9 I illustrate a construction wherein the folds 31 and 32 are cut away
from about the centre of their inclined edge, said cuts being shown at 40, and extending
backward to the score lines 14 and 15, to be met by other cuts formed on the score
lines which extend from the outer edge of the top portion 30 inward to the cuts 40;
for certain classes of goods this form of box will be found more desirable than the
forms heretofore described.
In figure 10 1 illustrate a construction wherein the blank is cut away upon the line
of the score 11, thus forming an open top box, and in connection with this box I
employ a cover 41 which is made from a blank in all respects similar to the blank
employed to form the box represented beneath the cover, except that the cover-blank
is slightly larger than the box-blank, and in this case, if it is desired to dispense with
paste or glue in making the box, metallic retaining-clips 42 and 43 may be employed
to hold the end-flaps 26 and 27 against the ends 22 and 23, the clip 43 being formed
with over-turned ends 44, one of which ends embraces the paste-flap 28, as illustrated,
the two clips holding the blank sections in position after they have been bent and
folded to form the box. It will, of course, be understood that the clips could be used
upon the box as well as on the cover, and by using the clips the blanks may be shipped
Hat," ie. without folding. This, latter form of box is designed especially as a
receptacle for heavy articles such as hardware.

page_text: Improvements in Paper Boxes.
I JOSEPH TAYLOR CRAW of Jersey City in the County of Hudson and State of
New Jersey, United States of America Paper Box Maker do hereby declare the nature
of this Invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
This invention relates to the manufacture of Paper Boxes, and especially to that
class of boxes commonly known as "siftless knock down boxes," the main objects of
the invention being to provide a box which may be quickly set up, and which when
set up will have a perfectly flat springless bottom without exposed folds, the blank
from which the box is made being so cut and scored, that when the parts are adjusted
to place they will be, as it were, locked against displacement, and that, too, without
the aid of paste or other viscid material except upon the main paste-flap.
To the ends named, the invention consists of a box made from a blank that is cut
and scored to form the sides, ends, paste-flap, double hottom, and rectangular end-
flaps of the box, as will be hereinafter described.
Reference is to be had to the drawings left with my provisional specification in
which similar figures of reference indicate corresponding parts in all the views.
Figure 1 is a view of the blank from which my box is formed, the blank being so
cut that when folded it will constitute a box having my preferred form of top or
cover.
Figure 2 is a perspective view of the partially completed box, the inner bottom-
flap being represented partially folded to place, while the main bottom and the end
flaps are represented as they appear prior to being moved to place.
Figure 3 is a perspective view of the box, wherein the parts of one side and end
of the box are broken away, the several parts of the blank being represented as they
appear when folded to complete the bottom of the box, the top of the box being
represented as it appears prior to the closing of the box.
Figure 4 is a longitudinal sectional elevation of the box.
Figure 5 is a cross-sectional elevation of the same.
Figure 6 is a longitudinal sectional elevation of a modified construction, the different
folds being given to the blank to form the bottom, while the top is represented as
being formed with tucks.
Figure 7 is a cross-sectional elevation of a box constructed and folded as represented
in Figure 6, the top, however, being represented as it appears when open.
Figure 8 is a plan view of the form of box illustrated in Figures 6 and 7.
Figure 9 is a perspective view of a modified form of box ; and
Figure 10 is a perspective view of a box wherein the cover is male separate from
the main body of the box but from a blank that is the same except as to size.
In making such a box as the one illustrated in the drawings above referred to, take
a rectangular blank and score it longitudinally at 11 and 12 and transversely at
13, 14, 15, and 16, cutting the blank at 17 and 18 upon the line of the score 12, and
at 19 and 20 upon the line of the score 13; also cutting the blank from point of the
intersection of the scores 11 and 13 diagonally to the edge of the blank at the end of
the score 14, and diagonally from the intersection of the scores 11 and 16 to the edge
of the blank at the end of score 15.

page_text: In the blank so formed, 20 and 21 become the sides of the box ; 22 and 23, the
ends; 24, one thickness of the bottom, and in my preferred manner of folding, the
inner thickness of said bottom, while 25 forms the other thickness of the bottom,
preferably the outer thickness; 26 and 27, the end-flaps; 28, the main paste-flap;
29 and 30, the double top, and 31 and 32 the top-folds.
In forming a box from the blank illustrated in Figure 1 and described as above, the
blank is first bent upon the score 14, the paste-flap 28 being bent over so as to be
borne upon by the side 20. The bottom portion 24, is then bent in and pressed
against the side 20, and the flaps 26 and 27 folded upon the bottom portion 25. Said
bottom portion is folded down until the lower opening of the box is closed. The flaps
26 and 27 are then pressed out against the inner faces of the ends 22 and 23, and the
portion 24 is pressed down between the flaps 26 and 27 and against the upper face
of the outer bottom, 25. This is my preferred manner of folding the box, and in
practice the bottom formed as described will be found to be perfectly flat and at the
same time very secure; but if deemed advisable, lines of paste may be applied to the
outer faces of the flaps 26 and 27, so that said flaps will adhere to the inner faces of
the ends 22 and 23. This pasting, however, will be found to be entirely unnecessary
and superfluous except when exceedingly fine material is to be packed within the box.
Boxes laving bottoms formed as above described, may be placed so as to stand in a
vertical position upon the pan or platform of any of the ordinary forms of automatic
scales, and being so placed will receive their charge or load from the scales without
tilting one of the most serious objections of the ordinary form of knockdown box
being that the numerous tucks and folds caused by the adjustment of the parts produce
a bulging, springy bottom, which prevents the boxes from standing in a steady vertical
position.
After the boxes have been filled, their open ends are closed by folding in the folds
31 and 32 upon the line of scores 33 and 34, which scores are drawn inward to
intersect the angles formed by the meeting of the scores 11 and 14, and 11 and 15.
After the folds 31 and 32 have been adjusted, as described, the outer top-flap, 29, is
folded down and pasted to the upper surface of the inner top-flap, 30, and in this
manner form my preferred style of box; but in certain cases it might be deemed
advisable to substitute cuts for the scores 33 and 34, such a construction being
represented in figures 6 and 7, and by so cutting the blank I form end-tucks 35, that
are integral with the top portion, 30, and in this top portion, 30, I form transverse
cuts 36.
In folding the box described, the top portion, 29, is folded down to close the top of
the box, the tucks 35 are folded down so as to extend at right angles from the top
portion, 30, which portion is then folded down, the tucks 35 passing inward between
the ends 20 and 23 and the ends of the top portion, 29, after which the locking
flaps 37 are bent over and their apices inserted within the transverse cuts 36 of the
top portion, 30, thus forming a box that will be practically siftless.
Instead of folding the bottom portion, 24, within the body of the box before intro-
ducing the end-flaps, 26 and 27, such end-flaps may be first folded upon the
bottom portion, 25, the portion 25 then folded over, and the end-flaps folded out
against the inner faces of the ends 22 and 23, after which the bottom flap, 24, may be
folded down and pasted to the outer face of the bottom-flap, 25.
A box constructed as describel will be found to possess sufficient strength and
rigidity to resist the test of a diagonal strain-that is, to resist the test of a strain
applied diagonally to its corners.
If desired, the end-flap, 27, may be cut off in a line with the score 16, as represented
in.Figure 1; but this cutting is not absolutely necessary.
In Figure illustrate a construction wherein the folds 31 and 32 are cut away
from about the centre of their inclined edge, said cuts being shown at 40, and
extending backward to the score lines 14 and 15, to be met by other cuts formed on
the score lines which extend from the outer edge of the top portion 30 inward to the
cuts 40; for certain classes of goods this form of box will be found more desirable
than the forms heretofore described.

page_text: In figure 10 illustrate a construction wherein the blank is cut away upon the line
of the score 11, thus forming an open top box, and in connection with this box I
employ a cover 41 which is made from a blank in all respects similar to the blank
employed to form the box represented beneath the cover, except that the cover-blank
is slightly larger than the box-blank, and in this case, if it is desired to dispense with
paste or glue in making the box, metallic retaining-clips 42 and 43 may be employed
to hold the end-flaps 26 and 27 against the ends 22 and 23, the clip 43 being formed
with over-turned ends 44, one of which ends embraces the paste-flap 28, as illustrated,
the two clips holding the blank sections in position after they have been bent and
folded to form the box. It will, of course, be understood that the clips could be used
upon the box as well as on the cover, and by using the clips the blanks may be shipped
flat," ie. without folding. This, latter form of box is designed especially as a
receptacle for heavy articles such as hardware.
