IMPROVEMENTS IN MACHINES FOR OPENING AND CLEANING COTTON AND OTHER FIBRE
Year: 1885

page_text: We WALTER LORD and WILL LORD, both of Canal Street Works, Todmorden
in the County of York, Machine Makers, do hereby declare the nature of said
Invention for IMPROVEMENTS IN MACHINES FOR OPENING AND CLEANING COTTON
AND OTHER FIBRE, to be as follows:-
Our invention consists first, in an improved arrangement for preventing the oil
employed for lubricating the shafts of the vertical cone drums from reaching the
outer surfaces of the drums and the belt or belts employed to drive the machine,
and secondly, for an improved arrangement for admitting air to the "beater
cylinder.
In performing the first part of our Invention we make an oil reservoir around
the upper part of the upper bearing of the vertical shaft to which the driving cone
is secured and we drill a hole through the bearing to the shaft; a piece of cotton
wick or other suitable material is placed in this hole to convey oil from the
reservoir to the shaft in the bearing; the top surface of the cone is dished or
recessed and a passage (or passages) is made through the solid part of the cone,
parallel to and preferably opening on to the shaft; any oil that passes through the
upper bearing is caught in the recessed part of the cone from which it can pass
through the before mentioned opening down the shaft to the lower bearing or
footstep.
When a driving pulley is keyed to the shaft we recess its inner part or boss and
make a passage (or passages) through the boss in order to allow oil to pass through
it to the lower bearing or footstep of the shaft.
Similar oil passages are or may be made through the upper bearing of the shaft
and the solid part of the other or driven cone.
}
In carrying the second part of our Invention into effect wo make a chamber by
ineans of a casing of perforated sheet metal preferably between the front edge of
the beater knife and its back or frame; air is admitted at the ends or other part of
this casing and is drawn in through the perforations by the revolving beater.
We employ movable dampers by adjusting which the draught may be regulated
to cause the fibre to pass evenly to the dust cages.

Improvements in Machines for Opening and Cleaning Cotton
and other Fibre.
We, WALTER LORD and WILL LORD, both of Canal Street Works, Todmorden,
in the County of York, Machine Makers do hereby declare the nature of said
Invention for IMPROVEMENTS IN MACHINES FOR OPENING AND CLEANING COTTON
AND OTHER FIBRE, and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
Our invention consists, first, in an improved arrangement for preventing the oil
employed for lubricating the shafts of the vertical cone drums from reaching the
outer surfaces of the drums and the belt or belts employed to drive the machine,
and secondly, for an improved arrangement for admitting air to the beater or
cylinder.
In performing the first part of our Invention we make an oil reservoir around
the upper part of the upper bearing of the vertical shaft to which the driving cone
is secured and we drill a hole through the bearing to the shaft; a piece of cotton
wick or other suitable material is placed in this hole to convey oil from the
reservoir to the shaft in the bearing; the top surface of the cone is dished or
recessed and a passage (or passages) is made through the solid part of the cone,
parallel to and preferably opening on to the shaft; any oil that passes through the
upper bearing is caught in the recessed part of the cone from which it can pass
through the before mentioned opening down the shaft to the lower bearing or
footstep.
When a driving pulley is keyed to the shaft we recess its inner part or boss and
make a passage (or passages) through the boss in order to allow oil to pass through
it to the lower bearing or footstep of the shaft.
Similar oil passages are or may be made through the upper bearing of the shaft
and the solid part of the other or driven cone.
In carrying the second part of our Invention into effect we make a chamber by
means of a casing of perforated sheet metal preferably between the front edge of
the beater knife and its back or frame; air is admitted at the ends or other part
of this casing and is drawn in through the perforations by the revolving beater.
We employ movable dampers by adjusting which the draught may be regulated
to cause the fibre to pass evenly to the dust cages and, to admit any required
portion of the air usually drawn through the grates or grids at the delivery side of
the beater.

And in order that our Invention may be fully understood and readily carried
into effect we will describe the accompanying Sheet of Drawings, reference being
had to the figures and letters marked thereon. Figure 1 is a side elevation, partly
in section, of an opening or cleaning machine to which our improvements have
been applied. Fig. 2 is a detailed view of part of the same and Fig. 3 is a view
of an alternative arrangement for regulating the air admitted to the beater or
cylinder:

page_text: Referring, first to Figs. 1 and 2.-a and b designate the pair of vertical cone
drums mounted on the shafts c and c¹, the cone a being the driver; d is the oil
reservoir which we make around the upper part of the upper bearing e of the shaft c
and el is the hole which we form in the bearing e and in this hole we place a piece
of cotton wick or other suitable material f to convey oil from the reservoir d to the
shaft c. The top surface of the cone a is dished at a¹ and passages a³ (or a passage)
are made through the solid part of the said cone parallel to and preferably opening
on to the shaft c as shown. On the shaft c is also keyed the driving pulley g
which is dished or recessed at g¹ and provided with, say two, passages g².
Any oil that passes from the reservoir d through the upper bearing e is caught
in the dish a¹ and flows through the passages a down the shaft c to the dish gl
thence through the passages g³ to the footstep h. In like manner the driven cone b
is dished at b¹ and provided with passages be so that any oil escaping from the
upper bearing i runs down the shaft c¹ and passes through the passages b² to the
lower bearing or footstep j and thus none of the oil employed for lubricating
the shafts c c¹ can reach the outer surfaces of the cones a and b and the driving
pulley g and thus the oil is kept from contact with the belts employed to drive
the machine whereby much slipping is avoided while at the same time thorough
lubrication of the shafts and lower bearings or footsteps is insured.
Referring now to the second part of our Invention as illustrated by Fig. 1.-k is
the beater or cylinder and the beater knife; m is the casing of sheet metal which
is perforated at m¹ and is placed, according to our Invention, between the front
edge of the beater knife and its back or frame so as to form a chamber n; at
the back of the frame we form an additional or supplementary chamber o which
is placed in communication with the chamber n by means of perforations in the
frame l¹. Air is admitted to the chamber o at its ends or through perforations o¹
formed at the top as shown and the volume of air, admitted to the chamber n and so
to the beater or cylinder k, is regulated by employing a movable damper or dampers,
such as p, to open or close the perforations 12 as required.
In the alternative arrangement for admitting air illustrated by Fig. 3 we
admit air at the ends of the chamber n and dispense with the perforations 1,
chamber o and damper p. We regulate the volume of air admitted through the
perforations m¹ to the beater or cylinder k by means of a damper q, which may be
made in one or two pieces, free to be moved longitudinally to uncover or close the
perforations m.
In both arrangements shown and described the air is drawn in through the
perforations m by the action of the revolving beater k assisted by the dust fan
or fans.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed, we declare that what
we claim is
1. In an opening or cleaning machine, the improved arrangement for preventing
the oil employed for lubricating the shafts of the vertical cone drums from reaching
the outer surfaces of the cone drums and the driving pulley and the belts employed
to drive the machine, substantially as berein shown and described.
2. The combination with a cone drum mounted on a vertical shaft, of a dish or
recess in said cone drum to catch the lubricant escaping from the upper bearing of
the shaft and a passage or passages in the cone drum to permit the said lubricant
to pass downward toward the lower bearing or footstep substantially as herein
set forth.
+
3. The combination with the vertical cone drum a mounted on the shaft c
provided with a dished portion a¹ and a passage or passages such as a², of the
driving pulley g also mounted on the shaft c and provided with a dished portion g¹
and a passage or passages such as g³, all substantially as and for the purposes herein
described and as illustrated by the drawings.

page_text: 4. In a machine for opening or cleaning cotton and other fibres, the improved
arrangement for admitting air to the beater or cylinder, said arrangement con-
sisting chiefly of the use and application of the perforated casing m in combination
with movable dampers for regulating the draught of air admitted, substantially as
herein set forth for the purpose specified.
