Improvement in and relative to Paper-making Machinery.
I, ARCHIBALD HUGH MUNRO, 17, St. Luke Street, Barrow-in-Furness, in
the County of Lancashire, Paper Maker, do hereby declare the nature of this
invention to be as follows;-
In the first place, this improvement relating to paper makeing machinery,
it is to do away with a vacuum or suction box, this box is fixed stationery &
an endless wire cloth 66-mesh in the square inch passes over the top of it &
the water is sucked out from the paper pulp fibres as it travels along, it takes
great force & power & causes a great friction & wear & tear to the wire cloth
which only lasts a short time & are very expensive & the cost of changeing these
wires is also great.
In the second place, it is to do away with a very heavy roll called a top coucher
usually about 1 feet 10 in. dia. & a ½ in. brass shell with a very thick woolen
jacket covering on it, also a heavy wood guard board 10 in. by 4 in. which
runs the full length on the top of the roll & it is pressed down tight & a water
spray constantly running on to keep the jacket clean, the above couch roll works
on the top of the paper pulp fibres & the wire cloth as it travels along & very
often spoils a lot of stuff which is a very common accurance in this part of
the machine, also in makeing laid papers & name papers the laid lines & names
will be shown in the sheet more correct than the present machine make because
it will not have the weight of the heavy couch roll to press them out while
the paper pulp is in its wet state.
In the third place, the bottom couch roll which the wire cloth laps three
parts around it in its position, I convert this roll into a suction roll which
dispences with the top & bottom couch rolls & the main stationery vacuum or
suction box & all above explained. Thus my suction roll will travel the same®
speed as the wire cloth & does away with great friction & power & wear &
tear to the wire cloth, & will be of a great saveing, also will increase the out
put of paper for they will be able to drive the machines so much faster, & at
a considerable less cost.
My suction roll can be put to work to any paper machine of any size or width
& made to any dia., also any class of metals.
my said
Having now particularly described & ascertained the nature of
invention and in what manner the same is to be performed, I declare that what
I claim is my suction roll for wire parts for paper machine.
I wish to call it by name A. H. Munro's Jubilee suction roll.

Auchirald Hugh Munro, 17, St. Luke Street, Barrow-in-Furness, in

page_text: invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
In the first place, this improvement relating to paper makeing machinery,
it is to do away with a vacuum or suction box, this box is fixed stationery, &
an endless wire cloth 66' mesh in the square inch passes over the top of it &
the water is sucked out from the paper pulp fibres as it travels along, it takes
great force & power & causes a great friction & wear & tear to the wire cloth
which only lasts a short time & are very expencive & the cost of changing these
wires is also great.
In the second place it is to do away with a very heavy roll called a top coucher
usually about 1 feet 10 in. dia. & a 7 in. brass shell with a very thick woolen
jacket covering on it, also a wood guard board 10 in. by 4 in. which
runs the full length on the top of the roli & it is pressed down tight & a water
spray constantly running on to keep the jacket clean, the above couch roll works
on the top of the paper pulp fibres the wire cloth as it travels along & very
often spoils a lot of stuff which is a very common accurance in this part of
the machine, also in makeing laid papers & name papers the laid lines & names
will be shown in the sheet more correct than the present machine make because
it will not have the weight of the heavy couch roll to press them out while
the paper pulp is in its wet state.
In the third place, the bottom couch roll which the wire cloth laps three
parts around it in its position, I convert this roll into a suction roll which
dispences with the top & bottom couch rolls & the main stationery vacuum or
suction box & all above explained. Thus my suction roll will travel the same
speed as the wire cloth & does away with great friction & power & wear &
tear to the wire cloth, & will be of a great saveing, also will increase the out
put of paper for they will be able to drive the machines so much faster, & at
a considerable less cost.
The suction roll can be made any width or dia. to answer any paper machine,
also of any class of metals.
FIG. 1.
AA is showing complete suction roll as it will be when ready for paper machine,
B showing sections through AA, also, C the suction holes through into the inner
chambers which is connected up to the vacuum or suction pumps, D the outside
shell of the inner chambers answers as the shaft which is shown on the drawings,
E showing gland & packing arrangements to make the suction end air tight, Fi
showing suction pipe to the pumps, G a cap or lid to be taken off now & again
to wash out the inner chambers of the roll, also this end of the roll can be made
to connect to suction pumps if required, H driveing pulley & friction combind for
stoping & starting suction roll, V feather key, J pedestals, K hand wheel is fixed
on to a loose bush on outside shell D, the bush having a screw on the outside which
screws into the moveable end L, for screwing L out & in according to the different
widths of paper required on the machine, M rubber strips & plate are fixed on
with stud screws below ribs R, they will only be the length of the moveable
end L, it is to make sure that this part is air tight, P are bits fitted easy & fixed
on to the moveable end L to make part L level with the surface of the outside
shell of the roll S & R. W collar to keep moveable ends L in there positions,
also H in its position, N showing section end of suction pipe, F the open port
in the section is where the suction pipe is connected to the pumps, as the chambers,
of the inside shell, D travels to the open port in section F this is where the
water is sucked out of the paper pulp fibres.
The outer covering of roll A A. is constructed of ribs shown on drawing marked R
on A A, S is a solid rim at both ends of roll 3 in. wide to support the ribs marked R
shown on drawing A A and B and ribs are a fixed length from S to S shown on A A.

page_text: extends the full length to port F, L is showing moveable part to screw out &
in, in the space Y 10 in. at both ends, Y shown on B.
B is two star shaped sections X and X', section X is 10 in. shorter from each
end of outer covering of roll marked $ shown on A A, this allows the moveable
part L to screw out & in 10 in. in space Y on star shaped section X, X' the inner
section extends the whole length of shell, or tube D), N is sectional end of suction
pipe and F which is connected to the pumps.
The complete suction roll A A is built up of two star shaped sections X and X',
the the inner section X' extends the whole length of the shell or tube D), and the
outer section X only the length of the roll proper over which the paper pulp
passes, the two sections communicate with one another by means of apertures
which admit water to the compartments of the inner section X', the water then
passing to the port F to the suction pipe F', the port F is so arranged as to
communicate only with those sections of the star shaped parts X and X¹ over
which the wire cloth & paper pulp are passing, the sections coming successively
within range of the suction port F and successively escaping therefrom as the roll
revolves.
