PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Outting Bagging Cloth and
the like.
I, ALFRED BYWATER STOTT, of Victoria Works, Mill Lane, Bradford, in the
County of York, Sack and Bag Maker, do hereby declare the nature of this
invention to be as follows:-
This invention relates to certain improvements in apparatus for cutting bagging
and the like, and is particularly applicable for what is known as botany bagging, and
has for its object the arrangement of the apparatus in such a manner that one
attendant only is required to each machine, thus dispensing with half the labour
hitherto required.
1 accomplish my object in the following manner :-The rotating cutter or knife
is secured on a shaft, driven in the ordinary manner, and attached to a suitable
table somewhat as hitherto, and to the back of said table I mount another shaft
upon which is secured a driving pulley, and loose upon said shaft is mounted a
forked lever the arms of which pass down each side of the before mentioned rotating
cutter and supports a short shaft upon which are mounted two wheels, and a pulley
to which rotary motion is communicated.
The sacking is fed to the machine in the ordinary manner, the attendant by
means of a treadle connected by a rod to the forked lever causes the same to move
on the before mentioned shaft as fulcrum and bring the guide wheels to bear upon
the sacking, such wheels, being driven by the pulley secured on the said shaft,
cause the bagging to be stretched tight and travel towards the rotating cutter and
thence away from the machine without the aid of a second attendant.
When the attendant releases his hold of the treadle the forked lever is operated
by means of a weight or spring and the guide wheels raised clear of the bagging
and table.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Cutting Bagging Cloth and
the like.
I, ALFRED BYWATER STOTT, of Victoria Works, Mill Lane, Bradford, in the
County of York, Sack and Bag Manufacturer, 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 :-
This invention relates to certain improvements in apparatus for cutting bagging
and the like, and has for its object, the arrangement of the apparatus in such a
manner that, one attendant only is required to each machine, thus dispensing with
half the attendance hitherto required.
In describing my invention, reference is made to the accompanying drawings, in
which
Fig. 1. represents a plan of a machine constructed according to my invention,
the casement being removed to more clearly show the mechanism.
Fig. 2. a section of same through line a. b.
Fig. 3. an elevation, part of the casement being removed, and
Fig. 4. a view showing a modification,

page_text: The casement of the machine is indicated by the letter A. and the frame by A¹
and mounted thereon is a shaft B. carrying the cutting knife C. driven by the
pulley D. from pulley E. on the main shaft of the machine.
The shaft F. is mounted on brackets G. supported and secured in any convenient
manner and rotated by means of pulley H. upon the shaft is also mounted a forked
lever J. between the arms of which rotates the before mentioned cutting knife, and
at one end of the said lever is mounted a short shaft S. upon which are secured two
discs K. K and a pulley L. for giving rotary motion thereto, the circumference of
each disc K. being conical and by preference fluted.
Below the table M. and under the before mentioned discs are two rotating 1
shafts N. to each of which is secured a disc P. upon the circumference of each rests
a circular plate Q. mounted on a stud in the centre in such a manner as to cause
the plate to rotate horizontally, or at the same inclination as the table M. the upper
surface of the plates Q. Q. near the circumference of each being cut to an angle
to suit the inclination of the circumference of the respective discs K. K.
Mounted in a convénient position near the bottom of the machine is a treadle
lever R. connected by rod Sf to the lever J. for the operation of the said lever, and
in order to keep the cutting edge of the knife C. sharp, I mount a rotating circular
stone or emery wheel T. in an adjustable manner, so that, the periphery of the
rotating stone or the like may, when required, be in contact with the angle of the
knife forming the cutting edge and thereby keep it sharp.
The sacking is fed to the machine by an attendant, who, on pressing down the
treadle lever R. operates the forked lever J. on the fulcrum shaft F. thus causing
the rotating discs K. K. to bear upon the sacking, and by the pressure of same
upon the plates Q. Q. the bagging is moved forward and stretched as it is cut and 2
travels to the right and left of the circular cutting knife without the aid of a second
attendant, the upper surface of each circular plate Q. being covered by a plate
shown by dotted lines except the portion indicated by U. of about one fourth of the
area of the plate.
On the attendant releasing the pressure on treadle lever R. the weight W.
secured on the bar of forked lever J. causes the pressure of the disc K. K. on the
circular plates Q. Q. to be entirely removed or relieved to the required extent.
The apparatus may be modified by mounting the lever J. under the surface of
the table M. and the discs N. N. on the shaft S. in lieu of discs K. K. the latter
being mounted on a shaft extending across the machine and in place of the circular
knife C. a band knife Y. mounted on suitable pullies to which rotary motion is
given may be utilized for the purpose of my invention.
Having now particularly described and ascertained the nature of this inven
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The combination of a cutting knife with a forked lever J. discs K. and P. and
the circular plates Q. Q. arranged substantially in the manner as described and
illustrated by the accompanying drawings.
2. The combination of the parts forming the complete apparatus arranged
substantially as and for the purpose herein set forth and illustrated by the
accompanying drawings.
