page_text: I, FRANK MACK EDMUNDS of Franklin Falls, in the county of Merrimac and
State of New Hampshire one of the United States of America, Miller Wright 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:-
Webs of paper taken from the paper-making machinery and wound upon rolls to
form rolls of paper to enter printing-presses and other machinery have to be
trimmed at each edge, so as to present a web of uniform width and with straight
edges.
The web is now trimmed as it is being wound upon a roll by means of rotating
cutters mounted on rotating shafts, and the ribbons of paper taken from both edges
are wound upon spools or rolls; but this is objectionable, for by reason of slits in
the edges of the paper and other causes the ribbons become broken, and the ends of
the ribbons are then liable to be caught by the travelling web and wound up with
it to the detriment of the web. A great deal of dust is also present during the
winding operation, which is very disagreeable and troublesome to the operator.
To obviate the employment of the spools for the ribbons and any liability of the
ribbons becoming wound with the web, and to collect the dust, I have provided
the usual trimming machine with mouths or receivers, having co-operating with
them an exhaust or suction apparatus which draws or sucks the ribbons and dust
into the said mouths, and taking the ribbons into pipes discharges them therefrom
into a suitable receptacle.
My invention consists, essentially, in the combination, with a paper-trimming
mechanism, of mouths or receivers for the ribbons of paper, and with an exhaust or
suction apparatus to operate, substantially as will be hereinafter described.
Figure 1 in side elevation represents a sufficient portion of a paper-trimming
machine to illustrate a practical embodiment of my invention. Fig. 2 is a front
elevation thereof; Fig. 3, a detail showing the shape of the mouth or receiver, and
Fig. 4 a modified form of mouth or receiver.
The frame A, the roll B, containing, as herein shown, the web or paper to be
trimmed, and the leading-roll B¹, and the shafts a a¹, provided with rotating
cutters a a³, two cutters for each edge of the web, are all as usual in paper-
trimming machines.
In front of the cutters a³ a³ in the direction of the travel of the web or paper,
drawn through the machine by any usual or suitable' feeding mechanism, I have

page_text: placed the open mouths or receivers b, forming part of the pipes 6', in connection
with the casing of the exhaust-fan C, which may be of any usual or suitable
construction, having the inlet and outlet mouths w and e, the fan rotating within
the casing also being of any suitable well-known construction.
Herein for sake of saving space on the drawings I have shown the exhaust-fan
as placed upon the floor next the trimming-machine; but it will be understood
that the said exhaust-fan may be placed at a remote distance from the machine,
and, if desired, on a lower or other floor of the building in which the machine is
operated.
In practice the pipes 61 61 will have telescopic or other sections, as at 6², to permit
the mouths or.receivers and parts of the pipes to be adjusted horizontally toward
and from each other, to adapt the open mouths or receivers to properly co-operate
with the cutters a² a³, which are made adjustable on their shafts according to the
width of the web and the width that the ribbons are to be cut from the webs.
In practice the ribbons cut from the edges of the webs will be inserted in the
open mouths or receivers, and as the web or paper is fed through the machine
the rotation of the shaft d of the usual belt-wheel in the exhaust-fan C will suck
and draw the ribbons into the pipes 61, and the said ribbons, after arriving
substantially at the point marked 2 of the exhaust-fan, are thereafter blown out
through the delivery-pipe e, a part of which is shown in Fig. 1, the said delivery-
pipe delivering the ribbons into a suitable box or receptacle adapted to receive
them.
In Fig. 4 I have shown a modified form of mouth or receiver, which may be
joined with the pipes b', said mouth or receiver being of tubular form, as shown
at 10, and extending a short distance in a direction parallel with the leading-roll of
the machine, suitable slots, 12, being provided on each side of the said mouth or
receiver and extending inward a short distance, through which the paper to be
wound is made to pass. By this form of mouth or receiver the dust present is
more easily drawn into the pipes or collected than by the mouth previously
described.
The web or paper passing beyond the cutters will be wound upon a suitable roll
or shaft in usual manner.
I do not desire to limit my invention to the employment of a fan by which to
create an indraft of air into the open mouths of the pipes B¹, for any other well-
known exhaust apparatus-such as a pump-might be used without departing
from my invention; but I prefer an exhaust-fan for cheapness and simplicity.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is
In a paper-trimming machine, the cutters to trim the edges of the web, combined
with pipes having open mouths to receive the ribbons or strips of paper cut from
the web, and also the dust present at such operation, and with an exhaust apparatus
to suck and take away from the trimming-machine the said ribbons or strips of
paper and dust, substantially as, and for the purposes hereinbefore described, set
forth, and illustrated in the drawings annexed.
