PROVISIONAL SPECIFICATION.
Improved Means for Preventing Injury to Attendants during the
Feeding of Paper or other Material to Heated and other Rolls or
Cylinders.
We, THOMAS SMITHI TAIT and JOHN HOOD, both of Inverurie Mills, Inverurie,
Scotland, Paper Factors, do hereby declare the nature of this invention to be
as follows:-
This invention has for object, certain improved means for preventing injury
to attendants during the feeding of paper or other material to heated and other
rolls or cylinders.
For the purpose of this invention, we fix or apply to the frame of a machine,
say, a couple of plates or screens of wirework or their equivalents with an open
mouth and gradually narrowed to the feed rolls or cylinders to enable sheets
of paper to be fed by hand and be directed into and between the rolls or cylinders,
the hands of an attendant being thereby kept well away and protected from
injury, such as by being drawn in, from too close application or from carelessness.
The invention is specially applicable in paper mills and callendering shops
where heated rolls or cylinders are used.
The plates or wire hand protector screens may be in pairs fixed, or one may
be a hinge jointed to be turned up or made to slide clear for temporary adjust-
ment or other requirement, and they can be arranged for adjustment to suit the
particular material to be fed to the rolls or cylinders, the back ends of the
plates or wire guards serving by a narrow slot to direct the material into the
rolls with certainty.
The plates, or the upper one only may be perforated to allow for escape of
steam or moist heat that may be formed.

page_text: Scotland, Paper Factors, do hereby declare the nature of this invention, and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
This invention has for object certain improved means for preventing injury
to attendants during the feeding of paper or other material to heated and other
rolls or cylinders.
For the purpose of this invention, we fix or apply to the frame of a machine,
say, a couple of plates or screens of wirework or their equivalents with an open
mouth, and gradually narrowed to the feed rolls or cylinders to enable sheets
of paper to be fed by hand and be directed into and between the rolls or cylinders,
the hands of an attendant being thereby kept well away and protected from
injury, such as by being drawn in, from too close application or from carelessness.
The invention is specially applicable in paper mills and callendering shops
where heated rolls or cylinders are used.
The plates or wire hand protector screens may be in pairs fixed, or one may
be a hinge jointed to be turned up or made to slide clear for temporary adjust-
ment or other requirement, and they can be arranged for adjustment to suit the
particular material to be fed to the rolls or cylinders, the back ends of the
plates or wire guards serving by a narrow slot to direct the material into the
rolls with certainty.
The plates, or the upper one only may be perforated to allow for escape of
steam or moist heat that may be formed.
In the accompanying drawings
Figure 1 is an end elevation of part of a paper-making machine with parts of
the framing removed and showing the safety guards fitted.
Figure 2 shews a plan of the guards in one plane and the opening between
their edges.
Figure 3 shews a plan of the guards with the opening between their sides.
In Figure 1 a, a, a, a, a, are the drying cylinders, b, b, b, are part of the
framing carrying the cylinders, c, c, c, are the felt rolls; d, d, d, d, d are the
endless travelling felts partially covering the cylinders, and between which and
the cylinders the workman's hand is in danger of being caught when leading in
the paper; e, e, e, represent the paper, with arrow marks, shewing the direction
in which it is travelling; f, f¹ together guard the upper intake, and f, f³, guard
the lower.
Each intake between travelling felt and cylinder is guarded by two fixed
plates as at f, f, or f², f, fixed to the framing, and so shaped and set as to make
between them a gradually narrowing opening through which the paper can be
passed with ease, but at the narrowest part, small enough to prevent the passage
of a hand.
The guards may be set as in Figure 2 or Figure 3, or they may be set at an
angle to each other, and may be fixed to the frames in the manner shewn in
Figure 1, or otherwise as may be most suitable according to the style of framing
used; thus the plate f³ in Figure 1 can be made to cover a large part of the.end
of the cylinder as shewn by dotted diagonal lines or it may be combined with ft,
to form one of the plates of the upper intake as shewn by dotted lines. The
guards may be made of any suitable material, close or open.
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:-
1
The improved means for preventing injury to attendants during the feeding
of paper or other material to heated and other rolls or cylinders, and consisting
of arranging two fixed plates, screens, or their equivalents set at each intake
between the travelling felts and drying cylinders, with the opening between
the plates or screens large enough to admit of the passage of the paper, but small

page_text: enough to prevent the hand of a workman from passing through, as described
and substantially as shown in the annexed drawings.
