PROVISIONAL SPECIFICATION.
Improvements in Machines for Dusting or Cleaning Rags and other
Paper-making Materials.
1, WILLIAM GILLESPIE, of New Cathcart, in the County of Renfrew, North
Britain, Foreman Papermaker, do hereby declare the nature of this invention to
be as follows, that is to say :-
My said invention has for its object to improve and simplify the construction
and action of machines for dusting or cleaning rags and other paper-making
materials.
In my improved machine the working parts are placed within a framing con-
structed of wood or iron, and the principal part is a cylinder made with iron end
rings or frames and with one or more intermediate, rings; the rings or frames having
fixed to them longitudinal bars which may be of wood. Coarse woven wire or wire
netting is fixed in a cylindrical form to the inside of the longitudinal bars; and on
the inside of the woven wire or netting but secured to the longitudinal bars there
are a number of inclined blades. At one end of the cylinder there is formed upon
the end frame an open inner ring of considerably smaller diameter than the outer
part of the frame, and this inner ring fits and turns upon a trunnion or hollow
bearing fixed to one end of the fixed framing. The spaces between the inner
and outer rings of the ead frame and the spokes connecting them are covered with
woven wire or netting. The other end of the cylinder is completely open and the
end frame or ring rests on and is guided by rollers attached to the fixed framing.
The cylinder is made to rotate by means of a belt or any suitable gearing; and it
is placed, by preference horizontally, but may be slightly inclined. The rags or
materials to be dusted are introduced through the trunnion at one end, and are
gradually moved towards the other end from which they are delivered by the action
of the inclined blades. The rotation of the cylinder repeatedly carries the rags
round and up to the highest point from which they drop getting thereby freed from
dust which passes through the woven wire or netting.
Instead of the end of the cylinder turning upon the outside of a fixed trunnion,
the end frame may be made with or have fixed to it a trunnion turning inside of a
fixed bearing ring or trunnion.
Instead of the rotating apparatus being cylindrical it may be made polygonal ;
and the blades may be hinged so as to turn down and facilitate the dropping of the
rags or materials as they reach the upper part.

Improvements in Machines for Dusting or Cleaning Rags and other
Paper-making Materials.
I, WILLIAM GILLESPIE, of Millholm Cottages, Cathcart, in the County of
Renfrew, North Britain, Foreman Papermaker, 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 said invention has for its object to improve and simplify the construction
and action of machines for dusting or cleaning rags and other paper-making
materials

page_text: In my improved machine the working parts are placed within a framing con-
structed of wood or iron and the principal part is a cylinder made with iron end
rings or frames, and with one or more intermediate rings, the rings or frames having
fixed to them longitudinal bars which may be of wood.
Coarse woven wire or wire netting is fixed in a cylindrical form to the inside of
the longitudinal bars and on the inside of the woven wire or netting but secured to
the longitudinal bars there are a number of inclined blad as shown in drawing
Figures 1 & 6 letter. F. At one end of the cylinder there is formed upon the end
frame an open inner ring of considerably smaller diametr than the outer part
of the frame as shown in drawing Figures 2 & 5 let.ered A, and this inner
ring fits and turns upon a trunnion or hollow bearing fixed to one end of the
fixed framing as shown in drawing Figures 2, 3 & 5 lettered A & B. The spaces
between the inner and outer rings of the end frame and the spokes connecting
them are covered with woven wire or netting. The other end of the cylinder
is completely open and the end frame or ring rests on and is guided by rollers
attached to the fixed framing as shown in drawings Figures 1 & 4 lettered C. D. & E.
The cylinder is made to rotate by means of a belt or any suitable gearing and it
is placed, by preference horizontally, but may be slightly inclined.
The rags or
materials to be dusted are introduced through the trunnion at one end and are
gradually moved towards the other end from which they are delivered by the action
of the inclined blades. The rotation of the cylinder repeatedly carries the rags
round and up to the highest point from which they drop, getting thereby freed from
dust which passes through the woven wire or netting.
Instead of the end of the cylinder turning upon the outside of a fixed trunnion,
the end frame may be made with or have fixed to it a trunnion turning inside of a
fixed bearing ring or trunnion.
Instead of the rotating apparatus being cylindrical it may be made polygonal;
and the blades may be hinged so as to turn down and facilitate the dropping of the
rags or materials as they reach the upper part.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
First. That the machine being on a level principle everything works
smoothly.
Second. The introduction of the blades in the inside is to the best of my
knowledge and belief an entire novelty and is advantageons for the more easily
retaining or delivering the material operated on.
Third. The trunnion principle is also to the best of my knowledge and belief a
novelty in this class of machine and possesses the advantage of rendering it safer
for the operator to work the machine and in my opinion lessens the wear and
tear of the machine itself.
