page_text: JOSEPH EBENEZER BLANCHARD Fairfield Road, Burgess Hill in the County of
Sussex, Builder 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 relates to an apparatus for the purpose of cutting off the list or
trimming expeditiously one, or both sides of paperhangings by one operation,
performing at the same time the process of unwinding and rewinding, and also to
enable the operator to guide the paper to the cutters and roller, thus effecting the
came efficiently and in less time than it has been possible hitherto.
The construction of the said apparatus and mode of operation is as follows.
There is a frame constructed of wood or other suitable material, to which is
attached or inserted a panel over which the paper passes during the operation,
this panel has a hole each side. for the cutters.
At one end of the machine. or apparatus there is a space formed, extending
crosswise and, having a bottom upon which rests a movable carriage. The said
movable carriage is for the purpose of holding in proper position the roll or piece
of paper which is intended to be cut or trimmed and consists of a board or other
suitable material, at each end of which there is a slotted bracket, one of these
brackets is kept in position (and when in use having its face bearing against the
end of the roll or piece of paper) by means of a spiral spring arranged to act under
the plate of the bracket, the other being adjustable to different width paper is
fastened with a set screw, these brackets support the ends of a rod or spindle,
upon this spindle is placed the roll or piece of paper to be cut, the spindle can be
taken out or replaced by drawing back the spring bracket.
For the purpose of working or moving backwards and forwards this movable
carriage I provide a lever, which is turned upon a pivot or pin, this lever is
connected with the carriage, and extends under, the rolling apparatus to the other
end of the machine; by a handle attached to this lever the operator can slide the
carriage horizontally, as may be required, and so guide the paper to the cutters and
ப

page_text: roller as it unwinds and rewinds. The lever can be arranged to act upon the rom
or piece of paper without using a separate movable carriage but simply sliding the
roll upon a spindle by having long brackets connected with the lever, but I find
the movable carriage as above described to answer the purpose best.
Near the opposite end to that occupied by the movable carriage, there is a roller
which is divided or split lengthwise, upon which the paper is rolled after it is cut,
or trimmed, this roller is arranged to revolve with a driving pulley, one end of the
roller being connected to the spindle of the pulley, and the other end has a movable
bearing held in position with a spring, so that by pressing the spring the roller can
be easily taken out or reinserted.
At a convenient distance from this roller and pulley there is another small pulley
which communicates a rotary motion to the two circular cutters, to the spindle of
this pulley is attached or secured with a nut one of the circular cutters, the shaft
carrying the other circular cutter is also attached to this spindle when it is
required. As in some cases it is only necessary to trim one side or edge of the
paper, the shaft carrying one circular cutter is connected to the said spindle by
being slipped on, and fastened by means of a set screw, and can be adjusted to suit
different widths paper, and when not required may be taken away, the other end
having a slotted pivot provided for that purpose which is also adjusted with a set
screw.
If it is required to cut or trim paper varying greatly in width from that in
ordinary use, I use a shaft carrying the adjustable cutter having a long thread, so
by turning the nuts which secure the cutter the same can be fastened at different
places on the shaft.
The small pulley and circular cutters are caused to rotate by means of an endless
band from the driving pulley.
In accordance with my invention I use circular steel cutters having teeth similar
to saws but all the teeth are beveled or have their basils in one direction crosswise,
when the cutters revolve the teeth cut against or comes in contact with fixed steel
plates or discs which are basiled in the opposite direction to the cutters, thus each
tooth coming in contact with the plates form shearing edges similar to that
produced by a pair of scissors, the teeth of the cutters require to be set or turned
slightly towards the plates, in order that the paper may pass clear of the cutters
after it has past the shearing edges.
The plates may be either square or circular, but I prefer to use circular plates
having a screw hole in the centre for fixing the same then by turning the plates on
the screw slightly a fresh edge is easily obtained as may be required for the circular
cutters to come in contact with.
These plates are screwed to bearers which are secured to the underside of the
panel, the bearers are secured by the screws passing through the slots in the panel
so as to be easily adjusted to the cutters and to different width paper.
In order to cut or trim a roll or piece of paper the sliding bracket should be
adjusted to the width of the paper, so that the spring bracket bears lightly against
the end of the roll, or piece, of paper when placed between the two, the spindle of
the movable carriage is then put through the roll or piece of paper, and placed in
its position in the brackets, the end of the paper brought over in contact with the
circular cutters, and attached to the split roller, by taking out one half of the roller
and replacing the same with the end of the paper between the two parts of the
roller, it will be necessary to cut a few inches of the list before connecting to the
roller, this is best done by a pair of scissors, then by turning the driving pulley;
which may be done by a handle attached thereto or by any other means, the paper
is wound upon the split roller and trimmed as it comes in contact with the
revolving cutters and the plates, the operator can turn the driving pulley with one
hand and guide the paper by the handle attached to the lever as before described
with the other, the listing which is cut off is led so as to fall under the machine by
slanting guides. When the roll or piece of paper is trimmed and rewound the split
roller can be taken out and withdrawn from the cut roll.

In thus giving a full description of apparatus, I wish it to be understood that
I do not claim any of the parts separately which are well known for the purposes
ascribed to them neither do I limit myself to the exact details before described so
Jong as the novel parts constituting my invention are retained.
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
(1.) The improved arrangement, and combination, of apparatus for cutting off
the list or trimming paperhangings, arranged to act substantially in the manner,
and for the purposes herein before described, and represented, in the drawings hereto
annexed.
(2.) The improved combination, and application of the lever for guiding the
paper to the cutters and roller, substantially as, and for the purposes before
described and represented in the drawings.
(3.) I claim the improved arrangement, combination, and application, of the
circular cutters and plates, by which the paper is cut substantially as, and for the
purposes before described and represented in the drawings.
Dated this 24th day of February 1886.
