Improvements in Guillotines for Paper, Cardboard, and the like.
ARTHUR WILLIAM STEVENSON 21, Bridge Street, Ardwick, Manchester, Box
Manufacturer, do hereby declare the nature of this invention to be as follows:-
My invention relates to improvements in guillotines by means of which it is
possible, when large quantities of material have to be cut, to effect a considerable
saving in time. Until now it has been customary when a workman wishes to
cut a large quantity of sheets of cardboard, paper and the like to a given size,
to first trim 35
one edge of each bundle, placing each bundle as he trims it upon
a table behind him or at his side. He then sets the guage of the guillotine so that
the boards will be cut to the required size, and feeds each of the bundles of boards
or the like into the guillotine a second time.
"
"
By my invention I construct an additional back guage to the guillotine which
is attached to the front of the ordinary back guage, and which may be called a
false guage," and which is arranged so that, by suitable mechanical means it will
slide up and down, or sideways, in slots or grooves prepared in the ordinary back
guage. This false guage is of metal carefully planed, and preferably from
toinch thick, and of suitable height, according to the thickness of material
usually cut on the guillotine.
Assuming the false guage to be inch in thickness, the operator, if he required
to cut down some bundles of boards to 30 inches long, would set his ordinary guage
to 30 inches. He would, before lowering or placing in position the false guage,
feed a bundle of boards to the ordinary back guage, thus "trimming" one edge
and cutting down to 30 inches. He would then place the false guage in position
and turn round his bundle of boards, and without unsetting his guage, trim the
other edge and cut down the bundle to the required 30 inches. It will thus be
seen that it is possible with one setting of the guage, to cut a large number of
bundles of material exactly to the required size, cutting both edges of each bundle,
one immediately after the other, instead of, as at present, cutting one edge of the
whole quantity, and afterwards cutting the other edge. Thus, only one handling
of the material is necessary instead of two.

[Price 8d.]

page_text: the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
-
The object of my invention is to construct an attachment to a guillotine or the
like by the use of which it is possible to considerably increase the amount of
work that can be turned out by such guillotine. In order to fully describe my
invention I have provided drawings of which
Figure 1, is a side view of a guillotine with my invention attached thereto.
Figure 2, is a front view of the same.
Figure 3 is an upright sectional view on the dotted lines A, A.
Figure 4, is also an upright sectional view on the dotted lines A, A, showing
an alternative construction of my attachment.
In the drawings, A is the frame-work of an ordinary guillotine, B is the knife-
holder, C is the knife D is the table and E is the ordinary back guage. In order
to carry out my invention, I take a square shaft M which I support by brackets K
and N in the position shown or in any similar suitable position. Upon this shaft
I place a chain-wheel and boss L having a square hole sufficiently large to allow
the chain-wheel to slide easily along the shaft. This boss is attached to the
guage E by an arm I, so that as the guage E is moved forward or backward by
the operator, the chain-wheel and boss L are also moved a corresponding distance
and direction. To the back guage E I attach by means of bolts or the like, an
additional guage F of metal or other suitable material, which I call a false guage,
and which will slide up and down in the slots T in the back guage E, as shown in
Figure 3 by the dotted lines S. A chain H is passed over the guide roller U
which is supported by a bracket J attached to the back guage E, and is also passed
over the chain-wheel L, a weight R being fixed at the other end of the chain to
balance the weight of the false guage F. At the front of the shaft M, in a posi-
tion convenient to the operator, is fixed a rope-pulley O with a rope P and treadle Q
attached. It will be easily seen that when the operator presses the treadle down
he causes the shaft M to turn and thus raises the false guage F.
In order to more fully explain the working of my invention I will assume that
the operator wishes to cut a large quantity of cardboard to the exact length of
30 inches. In the ordinary way he would first trim each bundle of boards sepa-
rately placing each bundle as he trims it on a table and would afterwards set the
back guage at a distance of 30 inches back from the knife and would cut down
each bundle to that size. This would necessitate two handlings each bundle hav-
ing to be put into the guillotine a second time. By my invention assuming the
false guage to be exactly half an inch in thickness he would set the back guage E
to 30 inches the false guage having first been raised by the pressure of the
treadle Q. The bundle of board would therefore when fed into the guillotine be
first cut to 30 inches, after which the operator would let down the false guage F
thus reducing the distance between the knife and the back guage to 30 inches.
He would then turn the bundle of board round, place it against the false guage F,
and thus cut it to 30 inches without removing it from the guillotine. He would
then again raise the false guage F by the pressure of the treadle Q, and repeat
the operation as many times as required until all the cardboard had been cut.
It is obvious that to cut both ends of a bundle of cardboard without removing it
from the guillotine is much quicker than to cut one end first, take out the card-
board and afterwards feed it a second time into the guillotine.
In Figure 4 I show an alternative construction which I prefer as being rather
simpler. In this the pressure of the treadle Q causes the false guage F to turn
upon an axle G into the position shown by the dotted lines S. Other mechanical
devices may also be employed in carrying out my invention, such as the moving
of a false guage forward by means of eccentrics.
I can if desired add a second similar arrangement with false guage to enable me
to cut all four sides of the cardboard at one setting of the back guage without
removing the cardboard from the guillotine.

page_text: 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. In a guillotine a moveable false guage for the purpose of reducing the dis-
tance between the knife and the ordinary back guage, and which false guage can
be instantly placed in and out of position as desired by the operator.
2. In a guillotine a combination of the shaft M, the chain-wheel and boss L,
the chain or the like H, and the false guage F, all substantially as and for the
purpose set forth.
