PROVISIONAL SPECIFICATION.
Improvements in Fur Opening and Blowing Machines.
I GILES ATHERTON of the Virginia Mills, Higher Hillgate, Stockport, in the
County of Chester, Hat Manufacturer, do hereby declare the nature of this Invention
to be as follows:-
My Invention relates to the machinery used in the opening of fur and in the
separating therefrom of the kemps hair and foreign matters as for example my
Invention is particularly applicable to the class of machines termed picker blowers.
In such machines the fur is opened by means of rapidly revolving pickers or spiked
rollers. Previously to my invention the bodies of these rollers have been made of
wood but owing to the changes to which such material is subject and to the want of
true balance in the rollers they have not been well adapted to run truly and sieadily
at the high speeds which are necessary. I make the roller bodies of brass or other
suitable metal the body of the roller being made in the form of a cylindrical shell
which is bored and turned to make it true or a length of tube may be used if the same
would be sufficiently true. The said shell is provided with metal ends which are fixed
upon the roller shaft and the steel pins are fixed in the metal shell. I may truly
balance the roller after it is completed. To prevent the lubricant from passing on to
the roller form each roller end or shaft end with a projecting collar and I form an
oil catcher upon the pedestal or bearing block and its cap the outer wall of such oil
catcher entering between the said collar and the roller end. Lubricant passing along
the roller shaft is thrown off by the said collar and falls into the oil catcher from
which if considered to be advisable a pipe may convey the oil to a conveniently
situated receptacle. The bearing may be freely lubricated to suit the high velocity of
the shaft without danger of the oil getting on to the roller and thereby damaging the
fur. The collars on the roller or shaft ends may be used as means for effecting the
balancing of the roller by cutting or shaping the collars as may be required. In
place of the ordinary sieves made of twine I use sieves made of strained copper or
brass wire which inay or may not be tinned or plated to prevent oxidisation. For the
travelling aprons I use woven material which is japanned or prepared on both sides
so as to be double faced such material not retaining the fine fur or dust upon its inner
or back surface to the same extent as the single faced material. I prefer to apply the
said improvements in combination with apparatus for automatically feeding forward
the fur to be treated.

Improvements in Fur Opening and Blowing Machines.
I GILES ATHERTON of the Virginia Mills, Higher Hillgate, Stockport in the
County of Chester Hat 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 and accompanying drawings:-
My Invention relates to the machinery used in the opening of fur and in the
separating therefrom of the kemps hair and foreign matters as for example my
Invention is particularly applicable to the class of machines termed picker blowers.
In such machines the far is opened by means of rapidly revolving pickers or spiked
rollers. Previously to my Invention the bodies of these rollers have been made of
wood but owing to the changes to which such material is subject and to the want of
true balance in the rollers they have not been well adapted to run truly and steadily
at the high speeds which are necessary. I make the roller bodies of brass or other

page_text: suitable metal the body of the roller being made in the form of a cylindrical shell
which is bored and turned to make it true or a lengtli of tube may be used if the same
would be sufficiently true.
In the drawings attached hereto one end of such a roller is shown in section.
In the said drawings a is the metal roller shell and b. b are the steel pins which aro
firmly fixed in the said shell. The butt ends of the pins may be screwed and the holes
to receive the pins may be tapped or the pins may be driven tightly into their places
or they may be suitably secured. When the roller is well made and truly balanced it
can be run at a very high speed. The cylindrical shell of the roller is provided with
metal end blocks c whereby the roller is keyed or secured to the roller shaft. d. I
prefer to balance the roller after it has been provided with pins and been secured to
its shaft. In ordinary cases there is a tendency for the lubricant to pass from the
shaft bearings along the shaft to the roller ends whence it is thrown off amongst the
fur and damages the same. To prevent this I form a collare upon each end block as
represented in Fig. 1 and I form recesses or oil catching chambers e. e. in the bearing
pedestal and its cap and I arrange for the outer wall of such oil catcher to enter
between the said collar and the roller end. Lubricant passing along the roller shaft
is thrown off by the said collar and falls into the oil catcher from which if considered
to be advisable a pipe may convey the oil to a conveniently situated receptacle. The
bearing may be freely lubricated to suit the high velocity of the shaft without danger
of the oil getting on to the roller and thereby damaging the fur. Fig. 2 illustrates a
modification in the construction. In this example the collar d' is formed upon the
roller shaft a swell being also formed upon the shaft to receive the roller end
block in order that such block may be capable of being passed over the collar d'.
It will be seen that the result will be the same in both examples. The collars on the
roller or shaft ends may be used as means for effecting the balancing of the roller by
cutting or shaping the collars as may be required. In place of the ordinary sieves
made of twine I use sieves made of strained copper or brass wire which may or
may not be tinned or plated to prevent oxidisation. Such sieves besides being more
durable than the ordinary sieves do not become clogged with the fur or fine fluff to
the same extent owing to the fact that such fluff has less tendency to adhere to the
smooth surface of the wire. For the purpose I have so far found soft or annealed
brass wire to be the most suitable. For the travelling aprons I use woven material
which is japanned or prepared on both sides so as to be double faced such material
not retaining the fine fur or dust upon its inner or back surface to the same extent as
the single faced material.
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.
1. The improved construction of picker rollers and bearings for the same
substantially as and for the purpose set forth and indicated.
and with metal end
2. The brass or metal cylinder a provided with steel pins
blocks whereby the roller can be fixed upon its shaft substantially as and for the
purpose set forth.
.
3. The collar c' or 'in combination with the oil catching recess or recesses e for
the purpose set forth.
4. In machinery used for the indicated purposes sieves made with soft brass or
with metal wire as set forth.
5. In machinery used for the indicated purposes travelling aprons made of woven
fabric which has been japanned or prepared on both sides so as to have smooth faces
below and above as and for the purpose set forth.
