PROVISIONAL SPECIFICATION.
Improvements in Clearers for Yarns.
I, MALCOM MACGREGOR GREEVES, of The Forth River Mills, Falls Road,
Belfast, in the County of Antrim, Ireland, Manager, do hereby declare the nature
of this invention to be as follows:-
In the reeling or winding of yarn from flax it is customary to pass the material
through a device called a clearer to remove lumps etcetera therefrom.
These have hitherto been made in the form of a bracket to be screwed or bolted
to the frame with a thin slot or saw cut the size of which is regulated and adjusted
by means of a set screw passing through from one side to the other. This form is
objectionable as it is difficult to keep the two jaws or sides of the slot parallel,
and to set them the required distance apart, besides being liable to be tampered
with by the workers causing loss of time in adjusting the slot for each change in
thickness or lea of yarn.
My invention consists essentially in the combination of a detachable or movable
clearer with a holder or bracket in which it can be easily fixed and from which it
can be quickly removed and replaced by another of different size.
In carrying out the invention I construct the clearer in the form of a flat plate
with a slit or saw cut of the required gauge extending from the top to the bottom
or nearly so. This flat plate I fit into a bracket or holder provided with a slide
or groove or other receptacle for it. The bracket is provided with side lugs to
receive a set screw at each side and at or near the bottom is a small spring bolt or
catch which engages with a nick or groove in the clearer and holds it in position.
Instead of a spring catch a screw or other device may be used to secure the clearer
in its position in the holder.
The bracket or holder is affixed to the frame by a screw or bolt or in any other
convenient manner.
By this arrangement no adjustment of the slot or slit in the clearer is required
as a clearer of proper size will be placed in the holder; no tampering with the
clearer will be possible by the workers as the slot is of a fixed size; and the
clearers can be readily changed from one size to another without loss of time.

COMPLETE SPECIFICATION.
Improvements in Clearers for Yarns.
I, MALCOM MACGREGOR GREEVES, of The Forth River Mills, Falls Road,
Belfast, in the County of Antrim, Ireland, Manager, 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 :-
In the reeling or winding of yarn from flax it is customary to pass the material
through a device called a clearer to remove lumps etcetera therefrom.
These have hitherto been made in the form of a bracket to be screwed or bolted
to the frame with a thin slot or saw cut the size of which is regulated and adjusted
by means of a set screw passing through from one side to the other. This form
is objectionable as it is difficult to keep the two jaws or sides of the slot parallel,
and to set them the required distance apart besides being liable to be tampered
.

thickness or lea of yarn.
My invention consists essentially in the combination of a detachable or movable
clearer with a holder or bracket in which it can be easily fixed and from which it
can be quickly removed and replaced by another of different size.
It will be fully described with reference to the annexed drawings in which sufficient
of a reeling frame is shown to illustrate the invention.

thereon.
Fig. 2. End elevation of same.

Fig. 6. Side elevation in section.
Fig. 7. Front elevation of bracket with clearer plate removed.
Fig. 8. Front elevation of clearer plate.
Fig. 9. Side elevation of clearer plate.
I construct the clearer A with a removable plate B and bracket or holder C.
The removable clearer plate B is formed with a slit or saw cut 6 of the required
gauge extending from top to bottom or nearly so.
The removable clearer plate B fits into the bracket or holder C provided with a
groove or other receptacle to receive it and at the bottom of the bracket C
place a small spring bolt or catch D and provide in the clearer plate B a groove
or nick d with which the bolt D engages and secures the plate in position. Instead
of a spring catch a screw or other device may be used to secure the clearer in its
position in the holder.
The clearer A is affixed to the front of the machine by a screw or bolt passing
through a hole e in the bracket C or in other convenient manner and between each
of the clearers is fitted a guide wire E. The wire E fits into holes in the side
lugs F and are secured therein by the set screws f'.
The clearer plate B is removable and a number of plates are provided with slits
or cuts of different size or gauge. By this arrangement no adjustment of the slot
or slit in the clearer is required as a clearer of proper size will be placed in the
holder; no tampering with the clearer will be possible by the workers as the slot
is of a fixed size; and the clearer can be readily changed from one size to another
without loss of time.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
In a yarn clearer for use in reeling and winding machines the combination of the
removable clearer plate B provided with slot or slit of the desired size with the
fixed bracket or holder C provided with grooves c to receive the clearer plate, and
the spring bolt D or its equivalent which engages with and secures the clearer
plate, with or without the guide wires E substantially as described.
