Improvements in or relating to Machines employed for Striking,
Scouring, and Brushing Leather."
We, ROBERT GLEIC BEAN, and CHARLES HENRY GOUGH, of the Gibralter
Leather Works, Knostrop, near Leeds, in the County of York, Leather Manu-
facturers, do hereby declare the nature of this invention to be as follows:-
Hitherto on machines, having a rotating drum or wheel, employed in the
manufacture of leather for striking, scouring, and brushing it has been customary
to cement the striking or scouring tool (which is made of slate or stone) into an
iron trough or box which is bolted on the periphery of the drum or wheel.
In this
method of fixing the tool in position, not only is there a great loss of time in
waiting for the cement or fixing mixture to harden, but also should the tool become
damaged or when it has worn away, before it can be removed from its holder the
cement requires to be chipped or burnt away thus entailing further loss of time and
expense.
*
Now the object of this invention is to overcome these difficulties, and to provide
a cheap, simple, and effective method of securely fixing the tool in position
without the use of cement or loss of time either in the application or removal of
the tool.
According to our invention instead of making the tool rectangular as at present,
that is with its ends and sidesiat or about right angles with its base, we make one
or both sides and ends to taper, the end or ends being preferably made to taper
more than the side or sides..

The tool shaped as above described is then placed in a metal rectangular box like
holder constructed in two portions. One of the portions--the holder proper-is
provided with a cavity shaped to suit the contour of the tool. This cavity extends
nearly the full length of the holder, and its depth is made about one half or three
fourths that of the tool. Into this cavity the tool is placed and is retained in
position by means of a retaining plate or piece which is bolted or otherwise fixed to
the holder and forms one of its sides. By having the sides and ends tapered
as described the tool is prevented from working out of its holder, and is thus
secured in position without the aid of cement or other fixing mixture.
Suitable packings of any soft material, such as strips of leather, may also be used
when desired for fixing the tool more tightly in its holder.
The above described holder may be bolted to the periphery of the drum or wheel
of the machine as in the ordinary machine either between the brushes or at suitable
intervals apart.
By the use of the herein described means a worn or damaged tool may be
removed from its holder and a new tool inserted therein without removing the
holder from the drum or wheel.

Improvements in or relating to Machines employed for Striking,
Scouring, and Brushing Leather."
We ROBERT GLEIG BEAN and CHARLES HENRY GOUGH of the Gibralter
Leather Works, Knostrop near Leeds in the County of York, Leather Manu-
facturers, 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 :-
Hitherto on machines having a rotating drum or wheel employed in the
manufacture of leather for striking scouring and brushing it has been customary to
cement the striking or scouring tool (which is made of slate or stone) into an
iron trough or box which is bolted on the periphery of the drum or wheel. Iv
this method of fixing the tool in position, not only is there a great loss of time in
waiting for the cement or fixing mixture to harden, but also should the tool become
damaged or when it has worn away, before it can be removed from its holder the
cement requires to be chipped or burnt out. thus entailing further loss of time and
expense.
Now the object of this invention is to overcome these difficulties, and to provide
a cheap, simple, and effective method of securely fixing the tool in position
without the use of cement or loss of time either in the application or removal of
the tool.
In the drawings:-
Fig. 1 shows the application of tools and their holders constructed according to
this invention to a drum or wheel of a striking machine.
Fig. 2 an elevation of the tool and its holder with the retaining plate removed.
Figs. 3, 4, and 5, are respectively a longitudinal elevation (with retaining plate
removed) a transverse section and a plan of tool holder.
Figs. 6 and 7. a side and an end elevation of the tool.
A, is the tool which instead of being made rectangular as at present, that is with
its ends and sides at or about right angles with its base a, is made with both its
ends aa² and one of its sides a³ to taper so as to form a dovetail as shown at
Figs. 6 and 7.
In the drawings the ends a¹ a² are preferably shown to taper more
than the side a³. If desired both sides a3 a4 may be made to taper, but for the
majority of cases one tapering side will be found to be sufficient.
B, is a boxlike holder, made of cast, wrought, or malleable iron, or other
suitable material preferably, constructed in two pieces,-
-a holder (B) proper and a
retaining plate bolted thereto, capable of being bolted or otherwise fixed to the
periphery of the drum C as shown at Fig. 1. In the holder B is provided_a
cavity shaped to suit the contour of the tool A. This cavity extends nearly
the full length of the holder, and its depth is made say about one half or three
fourths that of the tool.
Into the cavity & the tool A is placed and is retained in position preferably by
means of a retaining plate which is bolted or otherwise fixed to the holder and
forms one of its sides. By having the sides and ends tapered as described, the tool
is prevented from working out of its holder, and it is secured in position without
the aid of cement or other fixing mixture. Suitable packings D of any soft
material such as strips of leather, may also be used when desired for fixing the tool
more tightly in its holder. Any desired number (eight are shown in the drawings)
of the above described holders may be bolted to the periphery of the drum or wheel
of the machine as in the ordinary machine either between the brushes (not shown
in the drawings) or at suitable intervals apart. By the use of the herein described
means a worn or damaged tool may be removed from its holder and a new tool
inserted therein without removing the holder from the drum or wheel, and when
the tool is inserted in the holder it is held securely in position without the aid of
cement.

page_text: Although we prefer constructing the holder B and fixing it to the periphery
of the drum or wheel of the machine as above described, we would have it
distinctly understood that any of the following methods may be adapted for
attaching a tapering tool such as A to the periphery of the drum, namely; both
sides of the holder may be made a fixture and one or both of its ends may
be made loose (to permit of the tool being inserted) and bolted thereto; or both
sides may be made loose and bolted to end pieces cast or formed on the base
plate or the holder B may be cast or formed in one piece, with a cavity therein
of a shape to suit the contour of the tool A. In this case the tool would be passed
into the cavity from the underside of the holder, and would be retained in position
by the periphery of the drum when the holder was bolted to it. Or a tapered hole
may be cast or formed in the rim e of the drum C and a plate bolted to its inner
periphery e for holding the tool in position. Or the holder B may be cast or
formed on the periphery of the drum with one or both of its ends or sides b
and bolted thereto and a cavity cast or formed in the holder to permit of the
tool being passed therein, and then retained in position by the loose side or end
piece or pieces being bolted in position. Or a tapered cavity say about an inch
deep and the length of the tool may be cast or formed in the rim of the drum into
which the tool is passed and retained in position by means of a plate bolted to the
face of the rim.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is:-
1. The improvements in or relating to machines employed for striking, scouring
and brushing leather which improvements consist essentially in mounting a tool
provided with tapered ends and side or sides in a cavity formed for its reception in
a holder cast on or bolted to the periphery of the drum or wheel of the machine,
or in a cavity formed in the rim of the drum itself whereby it is retained in
position without the aid of cement or other fixing mixture substantially as herein
described.
2. In fixing or attaching a striking or scouring tool to the drum of a leather
striking, scouring or brushing machine, the use of a holder such as B made in one
or more portions in which is formed a cavity such as for the reception of a tool
such as A. provided with tapered ends and side or sides substantially as and for the
purposes set forth.
3. In machines for striking scouring and brushing leather the tool! A capable of
being fixed in its holders without the use of cement or other fixing mixture sub-
Stantially as herein set forth and illustrated.
4. In a machine for striking, scouring, and brushing leather the combination of a
tool such as A with a holder such as B having a cavity such as for receiving
the tool and a retaining piece such as for holding the tool in position without the
use of cement or other fixing mixture substantially as herein set forth and
illustrated.
5. In a machine for striking scouring and brushing leather the combination of
tool A, holder B, retaining piece b, with the drum or wheel of the machine as and
for the purposes set forth.
