I, WILLIAM JAMES ASHWORTH, of Kondrovo in the Government of Kalouga,
Russia, Mechanical Engineer do hereby declare the nature of this invention to be as
follows:-
My invention relates to flybars for paper pulping engines and has for its object the
reduction of what is technically termed half stuff to a fine pulp in a more expeditious
manner than by the flybars heretofore employed.
In carrying my invention into practice I form on or attach to the fly bars on the
cylinder of the pulping engine, to those on the bed plate, or to those on both the bed
plate and cylinder as may be desired, two or more cutting edges knives or blades
according to the class of work the machine is required to perform instead of a
single cutting-edge or knife as heretofore. I sometimes employ my improved
multiple bladed flybars in combination with the ordinary, or single bladed flybars
in the following manner that is to say, the cylinder of the pulping engine may
be provided with my improved double, or multiple bladed flybars, and the bed
plate may have the ordinary single edged fly bars or vice versa.
It is evident that the degree of fineness to which the pulp is reduced is in
direct proportion to the number of cuts it receives and therefore assuming that the
cylinder and bed plate have flybars with two cutting knives or edges on each, the
pulp will in each revolution of the cylinder undergo four times as many cuts as
can be obtained with the ordinary single edged flat bars.

page_text: Improvements in Paper-pulping Engines.
I, WILLIAM JAMES ASHWORTH, of Kondrovo in the Government of Kalouga,
Russia, Mechanical Engineer 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 :-
My invention relates to flybars for paper pulping engines, and has for its object
the reduction of what is technically termed "half stuff" to a fine pulp in a more
expeditious manner than by the flybars heretofore employed.
My said invention comprises the novel construction and arrangement as hereinafter
set forth with reference to the accompanying drawing, in which
Figure 1 shows my improved flybars as attached to the cylinder and bed plate of
a pulping machine.
Figure 2 shows in section and drawn to an enlarged scale two of the bed.plate
bars, and one of the cylinder fly bars.
Figure 3 shows the cylinder and bed plate bars as heretofore employed in paper
pulping engines.
In carrying my invention into practice I form on, or attach to the fly bars a, on
the cylinder A of the pulping engine, to the bars on the bed plate B, or to
those on both the cylinder and the bed plate; two or more cutting edges, knives or
blades preferably of a chisel shape as shown in Figures 1 and 2 according to the class
of work the pulping engine is required to perform.
The construction and arrangement of the fly bars which I preferably employ is
shown in detail in Figure 2. Each fly bar, in this instance, has two cutting edges
knives or blades instead of a single cutting edge as heretofore.
I sometimes employ my improved multiple bladed fly bars in combination with the
ordinary or singled bladed flybars in the following manner, that is to say, the cylinder A
of the pulping engine may be provided with my improved double or multiple
bladed flybars, and the bed plate B may have the ordinary single edged bars or
vice versa.
It is evident that the degree of fineness to which the pulp is reduced is in direct
proportion to the number of cuts it receives, and therefore, assuming that the cylinder
and bed plate have fly bars with two cutting edges, blades or knives on each, the pulp
will in each revolution of the cylinder undergo four times as many cuts as can be
obtained with the ordinary single edged fly bars.
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
First In a paper pulning onging the banc
the lindor and the bour Lan the

page_text: bed plate thereof provided with two or more cutting edges as and for the purpose above
specified.
Second. The arrangement of fly bars on the cylinder having two or more cutting
edges and ordinary or single edged bars on the bed plate or vice versa, as, and for the
purpose, above specified.
Third. The bars constructed and arranged substantially as described and shown in
the accompanying drawing as and for the purpose specified.
