page_text: We THOMAS WATSON of 85 Springfield Terrace Falls Road Belfast Mechanic and
JAMES DAVIDSON of 135 Grosvenor Street Belfast Mechanic do hereby declare the
nature of this Invention to be as follows:-
This Invention relates to that description of Fibre cleaning machines in which the
fibrous material is subjected to the action of pins or piercers carried by oscillating
reciprocating bars or frames the pins being arranged to pass through fixed grids or
gratings into the fibrous material fed between the said grids whereby the non-fibrous
portions of the material are broken and loosened from the fibrous portion. It has been
found in practice that the non-fibrous portion and dust thus removed from the material
under treatment is apt to accumulate at the base of and between the pins or piercers
behind the fixed grids thereby preventing the proper action of the machine and
necessitating the frequent stopping thereof for the purpose of clearing away the
accumulation.
Our Invention has for its object to obviate this defect and consists in placing loose
strips or pieces of wood or other suitable material upon the rows of pins or piercers
between the reciprocating frames which carry them, and the fixed grids or gratings
and so as to be free to move along the said pins. These strips of wood or clearers
which are subjected to constant vibrations either by the motions of the machine
when at work or if necessary by a motion acting on the bars or clearers may
be of such a width as to fill the spaces left between the fixed grids and the frames or
bars which carry the pins or piercers when the latter are advanced to their full extent
in the direction for piercing the material and may be maintained on the pins or piercers
by means of pins passed through or into the bars to engage with the piercers or they
may be otherwise secured thereon.
The loose strips or bars thus arranged effectually prevent the accumulation of dirt
between the pins and thereby increase the efficiency of the machine enabling it to be
worked almost continuously and without the necessity for stopping to remove
accumulations from between the pins.

Improvements in Fibre Cleaning Machines.
We THOMAS WATSON of 85 Springfield Terrace, Falls Road Belfast, Mechanic and
JAMES DAVIDSON formerly of 135 Grosvenor Street now of 97 St. Mary Terrace,
Crumlin Road Belfast, Mechanic 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 that description of fibre cleaning machines in which the
fibrous material is subjected to the action of pins or piercers carried by oscillating
reciprocating bars or frames the pins being arranged to pass through fixed grids or
gratings into the fibrous materials fed between the said grids whereby the non fibrous
portions of the material are broken and loosened from the fibrous portion.
It has been found in practice that the non fibrous portion and dust thus broken and
loosened from the material under treatment accumulates at the base of and between the
pins or piercers behind the fixed grids thereby preventing the proper action of the
machine and necessitating the frequent stopping thereof for the purpose of clearing
away the accumulation.
Our Invention has for its object to obviate this defect which we effect by means of
strips or clearers placed between the rows of pins or piercers so as to remove or
prevent accumulation of matter there-between.
We will describe our invention more particularly with reference to the accompany-
ing drawings in all of which the same figures and letters of reference are employed to
indicate corresponding parts.
Figure 1 is a sectional view shewing the relative position of the pins or piercers and
fixed grids with the strips or clearers between the pins or piercers.
Figure 2 is a face view of pin plate removed from the grids with the strips or
clearers in position.
Figure 3 is a sectional view at right angles to Figure 1 shewing means for giving
movement to the strips or clearers.
Figure 4 is a cross section of the strip or clearer shewn in Figure 3 and
Figures 5 to 8 are side views and cross sections of various forms of clearers which
may be employed.
Figure 9 illustrates an arrangement of moveable guide plates for imparting motion
to the clearers.
A are the pins or piercers set in the plate B and passing through the grid C.
Between the rows of pins or piercers A we place strips or pieces of wood or other
suitable material constituting clearers D. These strips or clearers Dare free to move
along between the pins or piercers A and fill or nearly fill the spaces left between the
fixed grids C and the plate B when the latter is advanced to the full extent in the
direction for piercing the material.
These strips or clearers D which rest upon the pins or piercers A are carried by
them as they advance and recede and they are preferably made with serrated edges as

page_text: shewn in figures 3 and 4 and to the right of figure 1 or they may be provided with
projecting pins as in Figures 5 and 6 and in the middle of Figure 1 or they may have
tufts of bristles as shewn in Figures 7 and 8 and to the left of Figure 1.
The object of these serrations projecting pins or bristles is to insure the prevention
of accumulation between the pins A.
To increase the efficacy of these strips or clearers D they have preferably an end wise
motion given to them as the pins A advance in the direction for piercing the material
which motion may be effected by means of plates or guides E which are fixed at a
suitable angle to cause the strips or clearers (when the pins are advancing and the
pin plate is carrying forward the said strips or clearers) to be moved endwise.
When the pins A are retreating the clearers D are by their frictional contact with
the said pins carried back with them and the opposite end wise movement of the strips
or clearers takes place, and the said strips or clearers are pushed endwise in the
reverse direction so as to scrape or touch the pin plate B when it again advances.
The guide plates E may be fixed or they may be carried on hinges e and be con-
nected together by a connection f as shewn in figure 9 so that when it is desired to
vary or reverse the endwise movement of the strips or clearers D the said guides
plates E can be set at a loss or opposite angle so as to lessen or alter the direction
of the end wise movement of the clearers. The irregular movement of the strips or
clearers D along and across the pins or piercers A and occasionally in contact with
the pin plate B prevents the accumulation of material between the said pins or
piercers and the machine can be worked without the repeated stoppages hitherto
necessary to remove accumulation.
Having now particularly described and ascertained the nature of the said Invention
and in what manner the same is to be performed we declare that what we claim is
First. In fibre cleaning machines bars strips or clearers situated between the rows
of pins or piercers substantially as and for the purpose hereinbefore described.
Second. In fibre cleaning machines, bars strips or clearers situated between the
rows of pins or piercers in combination with the inclined fixed or adjustable plates or
guiding surfaces (E) or equivalent means for giving endwise motion to the said bars
strips or clearers substantially as hereinbefore described.
