Improvements in Machinery for Cutting the Edges off Paper
Previous to Hanging.
I, JAMES OATES, of West Parade, Huddersfield, Yorkshire, Painter and Gilder, do
hereby declare the nature of this invention to be as follows:-
My invention has reference to a certain form of apparatus for cutting off the
edges of wall paper previous to its being hung.
The apparatus comprises two pairs of revolving discs or cutters placed at a suitable
distance apart so that as the edges of the paper are drawn through the cutters, such
edges are cut off. The roll of paper to be operated upon is placed on a spindle at
the feeding end of the machine, and after passing between the revolving cutters, the
said paper is wound upon a spindle, but in practice it is found that the uncut, roll of
paper delivers the said paper at a quicker rate than the taking up spindle can
receive it, and this arises in consequence of the diameter of the uncut roll being
larger than that of the taking up spindle consequently as the paper is delivered
quicker than it can be taken up, the said paper puckers or gets out of parallel with
the revolving cutters whereby the edges of the paper are not cut off straight or
parallel. To remedy this defect is the object of my invention, and this I accomplish
by the employment of one or more bars or rods placed in slotted framework between
the cutters and the uncut roll of paper, which rods put sufficient friction on the paper
to cause it to travel in a straight and even manner, whereby the paper is cut parallel
from one end to the other.

Improvements in Machinery for Cutting the Edges off Paper
Previous to Hanging.
I JAMES OATES of West Parade, Huddersfield, Yorkshire, Painter and Gilder
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:
My invention has reference to a certain form of apparatus for cutting off the edges
of wall paper previous to its being hung.
The apparatus comprises two pairs of revolving discs or cutters placed at a suitable
distance apart so that as the edges of the paper are drawn through the cutters, such
edges are cut off. The roll of paper to be operated upon is placed on a spindle at the
feeding end of the machine, and alter passing between the revolving cutters, the said
paper is wound upon a spindle, but in practice it is found that the uncut roll of paper
delivers the said paper at a quicker rate than the taking up spindle can receive
it, and this arises in consequence of the diameter of the uncut roll being larger than
that of the taking up spindle; consequently as the paper is delivered quicker than it
can be taken up, the said paper puckers or gets out of parallel with the revolving
cutters, whereby the edges of the paper are not cut off straight or parallel.
To

page_text: remedy this defect is the object of my invention, and this I accomplish by the
employment of one or more bars or rods placed in slotted framework between the
cutters and the uncut roll of paper, which rods put sufficient friction on the paper to
cause it to travel in a straight and even manner, whereby the paper is cut parallel
from one end to the other.
Such being the nature and object of my said invention, I will now proceed to
describe the same more fully, and for that purpose make reference to the accompanying
sheet of drawings illustrative thereof, wherein Fig. 1 is end elevation of the feeding
end of a machine employed for cutting paper.
Fig. 2 is plan view of same, and
Fig. 3 is section through the line A B of Fig. 2.
a represents the framework of the machine, having a main driving shaft bon
which are discs or cutters c caused to revolve by hand wheel d. A shaft e parallel
with shaft bis also employed, on which are fixed another pair of discs or cutters f,
such shaft being mounted in suitable bearings g, and made to revolve by a spur
wheel in gear with another spur wheel i fixed on the main shaft b, so that on
rotary motion being imparted to the main shaft, it is also imparted to the upper
shaft f, causing the two sets of discs to revolve for the purpose of cutting the paper
as it travels along. The roll of paper to be cut is shewn at j, and it is first placed
upon a spindle k, the ends of which rest in brackets l. The free or loose end of the
paper is passed over the table or bed m, between the revolving cutters and on to
two bars n placed horizontally at the back of the machine. So far the parts
described are not new, but have been in use prior to the date of this application for
patent, but practically the machine was a failure because the paper was delivered at
a quicker rate than it was taken up, in consequence of the unequal diameters of the
taking up and delivery rollers. To obviate this I employ two bars o and p, the ends
of which are placed loosely in slotted brackets q, fixed at each side of the machine,
such rods resting upon the paper, which I find puts sufficient drag or tension on the
said paper to prevent it puckering or travelling out of an even line, by which means
the edges of the paper can be cut off with great regularity. When the bars o and
are not in use, they are raised up the slotted bracket 9 and placed into the curved
notches at the top of the said bracket. The paper is drawn through the machine
by means of a pair of rollers s and t, the upper one being preferably made with an
india rubber tire. The cutting discs c and are made adjustable 'upon their shafts b
and e so as to permit the machine to cut paper of different widths. In order to adjust
the paper so as to cut strips of equal width off each side of the said paper, the
spindle k from which it is being wound is supported on arms or bars u capable of
oscillating upon the fixed ends so that the workman, by taking hold of the handle w,
can guide and control the paper laterally, thereby ensuring that the proper and
equal widths are being cut off the paper. On reference to the drawings it will be
seen that the taking up bars n are driven by a cord a working in grooved pulleys,
and when the driving, band becomes slack through stretching, or by variations of
temperature, or other causes, I provide that the said driven band shall pass under
an adjustable guide pulley y; see Figs. 3 and 4, where it will be seen that such guide
pulley y can be raised or lowered by means of nut z working upon the screw z¹
for the purpose of regulating the tension of the said driving band and taking up the
slack.
Instead of employing the bars or rods for putting friction upon the paper, the bed m
over which the paper travels may be covered with flannel, india rubber, or other
substance, which will put sufficient friction upon the travelling paper to make it travel
evenly over the said bed, and be presented to the revolving cutters in a straight and
parallel manner.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is

page_text: therewith of one or more bars such as o and p for placing tension upon the paper,
substantially as described.
Secondly. The employment of the adjustable pulley y, nut z, and screw z¹, as shewn
in Fig. 4 for adjusting the tension of the driving band.
Thirdly. In a machine for cutting edges off paper, the combination therewith of
the rotating discs c and f, tension rods o and p, with the peculiarly formed slotted
bracket g, all arranged and operated in the manner described.
Dated this 3rd day of July 1889.
