PROVISIONAL SPECIFICATION.
Improvements in Roll Paper Holders and Outters.
I, WILLIAM ROBERT REEVES, of 18. Fairbridge Road, Upper Holloway, in
the County of Middlesex, Manufacturer, do hereby declare the nature of this
invention to be as follows:-
This invention relates to roll paper holders and cutters in which a gravitating
knife is employed guided and supported by an inclined flange, the edge of said
knife resting upon the peripheral surface of the roll of paper, and adapted to sever
the paper when the latter is pulled diagonally against the edge of the knife.
knife is adapted to accommodate itself to the roll as it gradually becomes reduced
in size, or when a fresh roll is put in.
The
In carrying the invention into effect, the paper roll may be mounted on a mandrel
or roller of any suitable kind journalled in bearings formed in side supporting
frames. The said mandrel may if desired be provided with cones on which the
roll of paper itself is mounted, instead of the roll being mounted on the mandrel
itself.
The
The paper cutting knife is provided at each end with blocks or shoulders and
with projecting lugs formed to slide against inclined flanges on the side frames.
When the shoulders and lugs are in place so that the flange passes between them
the under side of the blade rests upon the peripheral surface of the paper roll, and
the blade will rise and fall as the size of the roll is diminished or increased.
blade will therefore always remain in contact with the periphery of the paper roll.
The shoulders and lugs aforesaid are so formed that the cutting edge of the
blade is in contact with the paper on the roll, the back edge of the blade being
preferably out of contact with the paper.
The knife may be secured to the blocks on which the lugs are by means of
screws, or it may be made in one piece therewith.
Instead of canting the knife as described it may be constructed with a slight
concavity from its cutting edge to its back portion.
Owing to the peculiar arrangement of the blocks or shoulders and the lugs in
conjunction with the inclined flange the paper cutting knife is enabled to resist the
upward strain or pull exerted upon it during the operation of cutting the paper.
The greater the pull exerted the firmer will the shoulder and lug be held against
each side of the inclined flange.

Improvements in Roll Paper Holders and Cutters.
I, WILLIAM ROBERT REEVES, of 18 Fairbridge Road Upper Holloway London
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 roll paper holders and cutters in which a gravitating
knife is employed, guided and supported by an inclined flange, the edge of said
knife resting upon the peripheral surface of the roll of paper, and adapted to sever
the paper when the latter is pulled diagonally against the edge of the knife. The

page_text: knife is adapted to accommodate itself to the roll as it gradually becomes reduced
in size, or when a fresh roll is put in.
In carrying the invention into effect, the paper roll may be mounted on a
mandrel or roller of any suitable kind journalled in bearings formed in side-
supporting frames. The said mandrel may, if desired, be provided with cones on
which the roll of paper itself is mounted, instead of the roll being mounted on
the mandrel itself.
The paper cutting knife is provided at each end with blocks or shoulders and
with projecting lugs formed to slide against inclined flanges on the side frames.
When the shoulders and lugs are in place, so that the flange passes between them,
the under side of the blade rests upon the peripheral surface of the paper roll, and
the blade will rise and fall as the size of the roll is diminished or increased. The
blade will therefore always remain in contact with the periphery of the paper roll.
The shoulders and lugs aforesaid are so formed that the cutting edge of the
blade is in contact with the paper on the roll, the back edge of the blade being
preferably out of contact with the paper.
Owing to the peculiar arrangement of the blocks or shoulders and the lugs in
conjunction with the inclined flange, the paper cutting knife is enabled to resist the
upward strain or pull exerted upon it during the operation of cutting the paper..
In the accompanying drawings
Fig. 1 is a perspective view of a roll paper holder and cutter constructed
according to this invention and of which
Fig. 2 is a view partly in end elevation and partly in transverse section and
Fig. 3 is a sectional view showing the mandrel. and cones for supporting the roll.
Like letters indicate like parts throughout the drawings.
A are the two side supporting frames or standards which are secured at their
lower ends to the base B and which are secured together at their upper ends by a
bar or preferably wooden rail C. A are the recesses or bearings, in the
standards A. in which the journals D' of the mandrel D are supported. The part
of each of the standards below the bearing A' may be of any desired construction
and either vertical or inclined but the part above said bearing is preferably of
angle section having two ribs or flanges à a' and is inclined or leans over as shown
in Fig. 2.
E is the paper cutting knife or tearing edge to each end of which is secured
preferably by screws E Figure 2 a block F, a cheek or shoulder F' of which is
adapted to work against the front face of the flange a of the appropriate
standard A and a pin or projection F carried upon the lug F' of which is adapted
to work against the back of said flange a.
The roll G may be supported or wound directly on the mandrel D or as shown
in the drawings it may be wound on a cardboard or equivalent tube H and mounted
on the mandrel by means of truncated tubular conies H' fitting in the ends of the
tube H and sliding on the mandrel D.
The front edge of the knife E is constantly pressed against the periphery of the
roll G the inclination and weight of the knife itself and the preponderating weight
of the blocks F at the front ensuring this result. As the roll G becomes gradually
smaller and smaller the blocks F slide down the upper part of the standards A
and whenever the paper is pulled diagonally upwards in the act of tearing it against
the edge of the knife E the blocks Fact as levers and the shoulder F and pin or
projection F of each block are pressed tighter against the respective sides of the
appropriate rib or flange a the knife E thus being prevented from being moved
upwards. It will be seen that the greater the pull on the paper upwards against
the edge of the knife E the firmner will the shoulders F¹ and projections F' be held
against the respective sides of the flanges a.
Instead of the knife E being cauted as shown in the accompanying drawings it
may be constructed with a concavity in its under surface extending from its front
edge to its back edge sufficient to prevent the back from touching the paper.
The before described apparatus if desired may be modified without departing

page_text: from the spirit of the invention for example the knife E may be formed integral
with the blocks F.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim is :-
1. In apparatus such as described the combination with a standard such as A A¹
having its upper portion a a¹ inclined of a block such as F having shoulders or
projections such as F F' substantially as and for the purpose described and
illustrated in the accompanying drawings.
2. In apparatus such as described the combination with a knife or tearing edge
of blocks such as F F F2 F3 substantially as described and illustrated in the
accompanying drawings.
3. The combination and arrangement of parts constituting the complete roll
paper holder and cutter substantially as described and illustrated in the accom-
panying drawings.
