I, WILLIAM PHILLIPS THOMPSON, Fel. Inst. P.A. of the Agency for Foreign
Patent Solicitors, 6 Lord Street, Liverpool in the County of Lancaster, and
323 High Holborn in the County of Middlesex, Civil Engineer, do hereby declare
the nature of this invention (a communication from abroad by the Morgan
Envelope Company, of Boston, County of Hampden, State of Massachusetts,
United States of America, Manufacturers) to be as follows:-
This invention relates to improvements in devices for holding rolls of paper and
cutting pieces of given length from a strip thereof, the object being to provide an
improved apparatus for manipulating a cylindrical roll of paper.
The apparatus is composed of a metallic frame having two arms projecting
horizontally therefrom. In the one arm is pivoted a geared segment having
thereon a projecting centre-pin extending towards the centre between said arms,
and adjoining the same, a second pin or projection parallel with the first.
The said centre pins serve as means for engaging the geared segment with the
end of a wooden or other cylindrical centre-piece of a roll of paper, as hereinafter
described, the end of the first pin entering a central hole in said.centre-piece, and
the end of the second pin entering a suitable hole near to centre one, whereby the
segment and the roll of paper are caused to have a coinciding rotary motion.
A projecting square centre piece on the geared segment in place of the centre
pin to enter a square socket in the end of the cylinder on which the strip of
paper is wound would answer the same end as the projections, but said square
socket is less easily formed than the two round holes as aforesaid.
The other arm of frame is provided with a removable centre-pivot, opposite said
projections, the inner or pointed end of which enters a central hole in the end of
the aforesaid cylindrical centre-piece of the roll of paper, and forms a support for
one end of the latter.
Said removable pivot, has a laterally projecting wing thereon between which
and its head is a slot.

page_text: This arm has a perforation through it corresponding in form to the transverse
section of the body of the pivot and its wing, and the thickness of the arm
surrounding said perforation is equal to the width of the said slot in the pivot.
The above described construction of the pivot and of the part of the arm which
received it, provides means for locking the roll of paper to the arms of the frame
and for conveniently removing a centre-piece from which the paper has been
unwound to place a full roll in the frame as follows:
By passing the end of the pivot through the perforation in arm, and turning it
partly round, the arm is engaged in the slot, in the pivot, preventing the latter
from moving endwise from the roll, and by turning the pivot back to its point of
starting, it is disengaged from the latter.
A knife having preferably a serrated edge is attached to suitable arins, which
have their ends pivotally engaged with the frame whereby the knife has a
vibratory motion between the arms of the frame.
A geared segment is attached to one of the arms which engages with the afore-
said geared segment on the arm.
A rolled strip of paper, having said cylindrical or other suitable shaped centre-
piece, having been placed in the frame, the operation of the device is as follows:
The knife and the outer ends of the arms swing downward against the lower
part of the base, by gravitation. The end of the strip of paper on the roll hangs
downward from the outer side of the latter.
By seizing and pulling the end of the strip of paper, the roll together with the
segment are rotated, and the engagement of the latter with the segment, on the
knife-arm causes the knife to swing up against the under side of the roll, its edge
projecting more or less beyond its periphery. At this point in the operation the
paper is drawn downward against the edge of the knife whereby a piece is cut off,
whereupon the knife drops by gravity to its point of starting and in so doing,
through its geared connection with the roll, causes the latter to rotate in a
direction contrary to that which was given to it by pulling the end of the paper-
strip as aforesaid, and to drop the end of the strip on the roll so that it hangs in a
pendant position from the latter ready to be seized as before.
By means of the above mentioned devices, pieces of paper of a given length, or
substantially so, may be cut from a rolled strip of paper, by proportioning the
circumference of the roll to the length required.
It will be seen that when the end of the rolled strip of paper is pulled and the
roll is rotated, the rotary motion of the latter is imparted to the knife giving it a
vibratory motion, and that when, by the separation of the piece of paper from the
strip the roll and knife are free, the vibratory movement of the knife by gravity
is imparted to the roll causing the latter to rotate.

. I, WILLIAM PHILLIPS THOMPSON Fel. Inst. P.A. of the Agency for Foreign
Patent Solicitors 6, Lord Street Liverpool in the County of Lancaster and
323, High Holborn in the County of Middlesex Civil Engineer, do hereby declare
the nature of this invention (a communication from abroad by the Morgan'
Envelope Company of Boston, County of Hampden, State of Massachusetts,
United States of America, Manufacturers) 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 improvements in devices for holding rolls of paper and
cutting pieces of given length from a strip thereof, the object being to provide an
improved apparatus for manipulating a cylindrical roll of paper.
In the drawing forming part of this specification, Figure 1, is a perspective
view of a device for holding rolls of paper and cutting off pieces from the paper,
embodying this invention, having one arm of the frame partly broken away.
Figure 2, illustrates detail parts hereinafter explained.
In the drawing A, is a suitable base of wood, or other material on which the
frame, B, hereinafter described is secured, and which provides convenient means
for supporting said frame in proper position in any convenient place, for use, in
holding a roll of paper.
A metallic frame B has two arms, c, c', thereon projecting horizontally therefrom.
In the arm c, is pivoted the geared segment d, having thereon the projecting center-
pin e extending towards the center between said arms, and adjoining the center-
pin e, a pin or projection o, parallel with the latter.
The said center-pin e, and the pin o serve as means for engaging the segment d
with the end of a wooden or other cylindrical center-piece of a roll of paper, as
hereinafter described, the end of the pin e entering a central hole in said center-
piece, and the end of the pin o entering a suitable hole- near the center one,.
whereby the segment and the roll of paper are caused to have a coinciding rotary
motion.
A projecting square center-piece on the segment d, in place of the center-pin e
to enter a square socket in the end of the cylinder f. on which the strip of paper
is wound, would answer the same end as the projections e and o, but said square
socket is less easily formed than the two round holes as aforesaid.
The arm c¹, of frame B is provided with a removable center pivot z opposite said
projections, e, the inner or pointed end of which enters a central hole in the end
of the aforesaid cylindrical center-piece of the roll of paper, and forms a support
for one end of the latter.
Said removable pivot & has a laterally projecting wing a, thereon between which
and its head is a slot n as shown.

page_text: The arm c¹ has a perforation through it corresponding in form to the transverse
section of the body of the pivot z and its wing x as shown and the thickness of
arm c¹, surrounding said perforation is equal to the width of the said slot, n in the
pivot s.
The above described construction of the pivot, %, and of the part of arm c¹,
which received it, provides means for locking the roll of paper to the arms of the
frame B, and for conveniently removing a center-piece from which the paper has
been unwound to place a full roll in the frame as follows:
By passing the end of the pivot, 2, through the perforation in arm, c¹, and
turning it partly round, the arm is engaged in the slot, n, in the pivot, preventing
the latter from moving endwise from the roll, and by turning the pivot back to its
point of starting, it is disengaged from the latter.
A knife, w, having preferably a serrated edge as shown, is attached to suitable
arms, m, which have their ends pivotally engaged with the frame, B, as shown in
Figure 1, whereby the knife has a vibratory motion between the arms of the
-frame B.
•
A geared segment y, is attached to one of the arms m, which engages with the
aforesaid geared segment on the arm, c.
A rolled strip of paper, h, having said. cylindrical, or other suitable shaped
center-piece, f, having been placed in the frame B, the operation of the device is as
follows.
The knife and the outer ends of the arms, m, swing downward against the lower
part of the base A, by gravitation. The end of the strip of paper on the roll h
hangs downward from the outer side of the latter.
By seizing and pulling the end of the strip of paper, the roll, h, together with
the segment d, are rotated, and the engagement of the latter with the segment y,
on the knife-arm, causes the knife to swing up against the under side of the roll,
its edge projecting more or less beyond its periphery. At this point in the operation
the paper is drawn downward against the edge of the knife, whereby a piece is cut
off, whereupon the knife drops by gravity to its point of starting and in so doing,
through its geared connection with the roll, causes the latter to rotate in a direction
contrary to that which was given to it by pulling the end of the paper-strip as
aforesaid, and to drop the end of the strip on the roll so that it hangs in a pendant
position from the latter ready to be seized as before.
By means of the above mentioned devices, pieces of paper of a given length or
substantially so, may be cut from a rolled strip of paper by proportioning the
circumference of the roll to the length required.
It will be seen that when the end of the rolled strip of paper is pulled and the
roll is rotated, the rotary motion of the latter is imparted to the knife, giving it
a vibratory motion, and that when, by the separation of the piece of paper from
the strip the roll and knife are free, the vibratory movement of the knife by.
gravity is imparted to the roll causing the latter to rotate.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, as communicated
to me by my foreign correspondents, I declare that what I claim is
1. In a device for holding a rolled strip of paper and cutting pieces therefrom,
a frame substantially as described having arms thereon, a roll of paper hung to
rotate between said arms, a knife having a pivoted connection between the latter,
and mechanism substantially as described, connecting said arms and knife with
said roll, whereby by pulling the end of said strip and turning the roll, the knife
is swung against the roll and by the return gravity movement of the knife, the
roll is given a rotary movement, combined and operating substantially as set
forth.
2. The frame B, having the arms, c, c', the geared segment d, having, the pro-
jections, e and o thereon, the removable pivot, x the knife, w, connected to arms,
having a pivotal connection with said frame, the geared segment y, attached to one;

page_text: of said arms and engaging with the segment d, combined with a rolled strip of
paper, substantially as set forth.
3. A roll-holder and paper severing device, for cutting or tearing pieces from
a strip of paper, consisting of a frame having two horizontally projecting arms
thereon, on one of which is pivoted a geared segment having thereon a center to
engage with the center-piece of a roll of paper, and having on its second.arm a
removable locking pivot substantially as described, to support one end of said roll
combined with a paper cutting knife pivoted to vibrate between said arms, having
thereon a geared segment engaging with said first-named segment, substantially as
set forth.
4. A roll holding frame, substantially as described, having arms thereon between
which a roll of paper is pivoted, combined with a paper severing knife having
a geared connection with said roll whereby the rotary motion of the roll imparts
a vibratory motion to the knife, and vice versa, substantially as set forth.
