HENRY PATTMAN TRUEMAN and JOHN GEORGE NEW both of 78 Parade
Birmingham Warwickshire Engineers and Machinists do hereby declare the nature
of this invention to be as follows:-
These improvements consist first of a novel arrangement of the parts carrying the
worm & worm wheel described in our previous patent No. 4923, 1884, whereby the
space required for working is considerably reduced.
This is accomplished by fixing a bracket for carrying the worm and worm wheel
in front of one of the upright members of the frame, instead of at the end of the
frame as heretofore.
The space vacated by the worm and worm-wheel is now occupied by the fly wheel
and crank.
The connecting rods from the worm wheel to the knife bar are placed immediately
behind the worm-wheel and in front of the knife-bar.
"
The Second point in these improvements is a novel arrangement of "self-clamp
or automatic means of clamping and releasing the material to be operated upon by a
Cutting machine. This is effected by placing a sliding nut or nuts on the framework
of the machine, the said nut or nuts are pressed downwards by a spring or springs,
or other suitable mechanism, and the springs are compressed by connection with the
knife-bar on its upward stroke. These sliding pieces or nuts are provided with
internal screw threads, and the usual hand wheel, screw, and clamp commonly
used on cutting machines, is fitted thereto. This arrangement is more simple and
direct than those hitherto employed.
The Third point in these improvements is the adoption of means whereby the
automatic action of the machine may be arrested, thus converting it into an
ordinary hand clamp cutting machine. This is effected by the insertion of a lock-
bolt or bolts which retain the sliding nut or nuts in their compressed position.
The paper is then clamped by working the screw passing through the nut, and
the machine is releived from the work of compressing the springs. This is an
advantage when a stoppage of the prime motor necessitates the working of a
machine by manual power.

page_text: The Fourth point in these improvements relates to the moving and holding of
the fence or gauge of Guillotine Cutting machines. This is usually effected by a
nut which fits in a long slot in the back table, this nut is necessarily short
compared to the width of the gauge and it cannot be lengthened without increasing
the space required for the working of the fence. In our improvement we discard
the use of the slot in the table as a guide for the nut, and carry the usual screw
for operating the gauge completely across the cutting machine from end to end,
where it runs in bearings. The nut working on this screw is provided with a
vertical extension which passes through the slot and is fixed to the gauge, and
there is also a horizontal prolongation which extends a long distance down the
screw shaft and there embraces the same. By this means we ensure a bearing
approximately as long as the gauge itself, thus reducing the error which is caused
by the wearing of the parts.

Improvements in Guillotine Paper Cutting Machines.
HENRY PATTMAN TRUEMAN and JOHN GEORGE NEW both of 78 Parade,
Birmingham, Warwickshire Engineers and Machinists do hereby declare the nature 2
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 :-
These improvements consist first of a novel arrangement of the parts carrying
the worm and worm wheel described in our previous patent No. 4923, 1884,
whereby the space required for working is considerably reduced. This is accom- 2
plished by fixing a bracket for carrying the worm and worm wheel in front of
one of the upright members of the frame, instead of at the end of the frame as
heretofore. The space vacated by the worm and worm wheel is now occupied
by the fly wheel and crank.
The connecting rods from the worm wheel to the knife bar are placed immediately 8
"behind the worm wheel and in front of the knife bar.
The second point in these improvements is a novel arrangement of "self-clamp"
or automatic means of clamping and releasing the material to be operated upon
by a Cutting Machine. This is effected by placing a sliding nut or nuts on the
framework of the machine, the said nut or nuts are pressed downward by a spring 3

page_text: or springs, or other suitable mechanism, and the springs are compressed by con-
Dection with the knife-bar on its upward stroke. These sliding pieces or nuts.
aro provided with internal screw threads, and the usual hand wheel, screw, and
clamp commonly used on cutting machines, is fitted thereto. This arrangement
is more simple and direct than those hitherto employed.
The Third point in these improvements is the adoption of means whereby the
automatic action of the machine may be arrested, thus converting it into an ordinary
hand clamp cutting machine. This is effected by the insertion of a lock-bolt or
bolts or other well known devices which retain the sliding nut or nuts in their
compressed position. The paper is then clamped by working the screw passing
through the nut, and the machine is releived from the work of compressing the
springs. This is an advantage when a stoppage of the prime motor necessitates
the working of a machine by manual power.
The fourth point in these improvements relates to the moving and holding of the
fence or gange of Guillotine Cutting Machines. This is usually effected by a nut
which fits in a long slot in the back table, this nut is necessarily short compared
to the width of the gauge and it cannot be lengthened without increasing the
space required for the working of the fence. In our improvements we discard
the use of the slot in the table as a guide for the nut, and carry the usual
screw for operating the gauge completely across the cutting machine from end to
end, where it runs in bearings. The nut working on this screw is provided with a
vertical extension which passes through the slot and is fixed to the gauge, and
there is also a horizontal prolongation which extends a long distance down the
screw shaft and there embraces the same. By this means we ensure a bearing
approximately as long as the gauge itself, thus reducing the error which is caused by
the wearing of the parts.
That our invention may be fully understood and curried into operation we will
describe the accompanying sheet of drawings, made to a scale of about 4 of an inch
to a foot and marked with letters of reference. The same letters refer to the same
parts of the machine throughout the drawings.
Fig. 1 is an end elevation of a cutting machine showing the bracket S carrying
the worm and worm wheel in front of the vertical iron bars A. A.
Fig. 2 is a front elevation of the same part shewing the relative position of the
bracket S and the fly wheel B.
"
The sliding nut C, the spring D and the hand wheel and clamp E, E 1 are also
shown.
F Fig. 1 shows the rollers used to lift the springs by contact with the knife bar G
during its upward stroke. H are bolts inserted in the sliding box I to arrest the
action of the spring when desired. Fig. 3 is a back elevation of the same parts as
Fig. 2 shewing the mode of applying two springs D. D. in lieu of the single spring D.
Fig. 2. Fig. 1 also shews a view of the screw J which is common to cutting
machines and is usually fixed immediately under the table. K is the long slide or
nut which embracing the screw J at L and M gives very long bearing to the fence
which is attached to M, and marked M' in the drawings. The working of the parts is
as follows: The turning of the flywheel B. Fig. 2 operates the worm N and the
worm wheel O Fig. 1. The connecting rod which moves the knife-bar is fixed to the
crank pin P. and occupies the space between the worm wheel O and the upright bar A.
The connecting rod Q and knife-bar G is also indicated in Fig. 2.
The working of the self-clamping apparatus is shown in Figs. 2 and 3. The paper
or substance to be cut is placed under the clamp E 1 which said clamp can be adjusted
to any distance from the pile by turning the hand wheel E in the manner usual to
cutting machines.
When the knife bar is in its upper position as shewn in Fig. 1
the rollers F on the box I keep the spring D in a compressed condition. The box 1
is connected to the sliding nut C by screws and consequently the sleeve and the
spring on it move with the said box I. As the knife-bar descends the rollers, the
box, the spring, the sleeve, the hand wheel, and clamp move with it until the clamp El
rests on the pile of paper, which said pile has to sustain the pressure of the spring,

page_text: and when the knife-har returns on its upward stroke the spring is again compressed
and the clamp lifted from the paper. When preferred two or more springs and
slides or boxes may be used, or more than one spring may be fitted to the same box.
When it is required to arrest the action of the spring the bolt H is inserted in a hole
drilled in the box so as to connect the box with the main frame, and the hand wheel E
will then work the clamp bar E 1 in the usual way. When it is desired to use longer
springs than shewn in Fig. 2 the nut C takes the form shewn in Fig. 3 and the
springs are connected at each end on suitable rods as shewn. The long nut K Fig. 1
has two vertical members L M connected by a horizontal portion marked K, the
vertical portion M is provided with an internal screw thread adapted to work on the
screw J. The portion markod L has a bored hole which fits accurately the plain
portion of the scrow J and also the tops of the threads cut upon the said screw.
is clear that the turning of the screw will cause the nut L. K. M. to traverse the
screw longitudinally and to stand at any desired position on the same and that the
usual paper gauge M¹ being fastened to M will partake of its motion. It is also
apparent that the bearing of the nut extending from L to M will prevent any
movement of the gauge about M as an axis.
It
Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed, we declare that what we claim is.
First. The use of a bracket placed in front of one end of the frame of a cutting
machine and carrying the operating wheels for the purpose of economising space,
substantially as described.
Second. The use of a spring or springs in combination with a sliding nut and hand
wheel clamp, substantially as described.
Third. The use of a sliding nut as and for the purpose described.
Fourth. The use of bolts or other well known devices for arresting the action of
the self-clamp apparatus, substantially as described.
Fifth. The use of a long nut sliding on a screw as and for the purpose described.
