Improvements in Guillotine Cutting Machines.
We THOMAS FURNIVAL of the Reddish Ironworks Reddish in the County of Lan-
caster, Engineer, EDWARD TUDOR Junior of the Reddish Ironworks, Reddish in the
County of Lancaster, Cashier, CHRISTOPHER PRESTON of Devonport Green Wilmslow
in the County of Chester, Gentleman, and WILLIAM BYWAY of Number 138 Princess
Street, Manchester, in the County of Lancaster, Plumber, 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 and
accompanying drawings:
Our Invention relates to the well known Guillotine machines which are used in the
cutting of paper in bulk and in the trimming of the edges of books or sewn matter
and are otherwise similarly used as is well understood. In such machines there have
been no ready means for taking up the wear of the parts carrying the fence or gauge
plate which is used to facilitate the adjustment of the work and the object of our
invention is to remedy this defect and also to improve the means for readily securing
the wood knife bed in position. We mount the said fence to slide toward and from
the said knife bed whilst remaining always parallel with the line of cut and we arrange
for the front portion of the table to slide to and from the front end of the back
portion of the said table and provide means whereby force can be exerted upon
the said front portion so as to securely clamp the wood bed between the parts.
Our Invention will be best described with reference to the accompanying drawings.
In the said drawings Fig. 1 represents a side elevation of so much of a Guillotine
machine as is necessary to the illustration of our Invention. Fig. 2 is a plan view of
the table of the machine and Fig. 3 is a cross section of the central portion of the
table drawn to the larger scale than the other two Figs. In the said Figs. a is the
back fixed portion of the table and bis the front portion which we render adjustable
as will be explained hereinafter. Upon the table a is mounted the fence c. In the
said table is formed a slot d which is made to be exactly at right angles with the line
of cut of the knife and is planed so that the sides of the slot are at right angles with
the planed face of the table so that a planed block e can slide toward and from the
knife bed f. The said block appears in cross section in Fig. 3 from which it will be
seen that the cheeks g. g₁ of the slot project below the underside of the table. One of
these cheeks namely the cheek g' in the example is truly planed on the outside in
order that a strip piece h may slide against the said cheek. The block e is cast or

page_text: formed with a projecting angle piece e¹ which is drilled and tapped to receive
adjusting screws i which bear against the strip h and press it into sliding contact with
the face upon the cheek g', so that the block is guided to slide truly in a straight
line without shake or looseness toward and from the line of cut at the same time
drawing the sliding block e against the inner face of the check g¹. The fence is
secured to the block e by means of bolts k. A screw nut is formed upon or fixed to
the block e and a screw shaft m which is mounted below the table in suitable bearings
works in the said screw nut. It will be seen that if the parts are suitably fitted to
work together the fence can be quickly moved into the required position by turning
the screw m in one direction or the other by means of a handle or hand wheel. The
cheek g' may be gripped between the block e and the strip with any desired degree
of tightness by adjusting the screws i. If considered to be desirable bolts may be
provided for securing the fence more firmly in its adjusted position or the bolts k may
be adapted to be used for this purpose. The strip h is by preference formed with
lateral end projections as indicated in Fig. 4 in order that it may be carried to and fro
with the block. In place of the nuts for pressing the sliding strip against the
cheek g' one or more springs or wedges might be used. The knife bed occupies
a space between the planed front end of the table a and the opposed planed end of the
adjustable table b. The latter is fitted to slide to some extent upon the framing.
A link n is hinged by one end to a fixed part of the table or framing. The other end
of the said link is acted upon by an excentric or crank which is formed upon or fixed to
a hand lever P which is mounted upon a stud fixed to the table b. The result of this
arrangement is that when the said handle is moved outward from below the table the
part b is slightly slid outward away from the knife bed so that the latter is released
but on the contrary when the hand lever is turned inward below the table the part b
is forcibly pressed toward the part a whereby the knife bed is tightly gripped as in a
vice. The table can be secured in its adjusted position by means of bolts or screws T.r.
which pass through slots in the said table. The link n is made in two parts connected by
means of a nut so that the link may be lengthened or shortened so as to regulate the
action of the excentric. The details may be varied so long as the sliding vice like
action of the front part 6 of the table is retained. Under some circumstances we may
use two or more such links and excentrics or cams.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
(1) The parts of a Guillotine machine constructed and acting substantially as
and for the purpose set forth.
(2) In a Guillotine cutting machine attaching the fence to a block which is fitted to
slide in planed ways or slides and operated by means of a screw shaft in combination
with means for adjusting the parts substantially as set forth and indicated.
(3) In a Guillotine cutting machine the block carrying the fence sliding in
contact with one face of the slot d and of the cheek g¹ and the strip sliding in
contact with and pressed toward the other or back face of the said cheek in com-
bination with a screw shaft m whereby the said block and the carried fence may be
moved toward and from the line of cut substantially as set forth and indicated.
(4) In a Guillotine machine the excentric crank or cam for moving forward the
part of the table in order to grip the knife bed ƒ substantially as set forth and
indicated.
