Improvements in Drawing and other Preparing Machinery for
Textile Fibres.
We, CHARLES DRENNAN, of 12, Battenberg Street, Foreman Fitter, JAMES
HEANEY, of 6, Clonard Street, Preparing Master, ARTHUR WILSON METCALFE, of
Grove Mill, Flax Spinner, and JAMES MACKIE, of Albert Foundry, Machine Maker,
all of Belfast, Ireland, do hereby declare the nature of this invention to be as
follows:-
_
The rubbers for the underside of the drawing rollers of preparing machinery
are held in position by means of a bar fixed parallel to the roller, and at a
suitable distance from it, to which springs are attached which reach towards
the roller. At or near their extremity may be attached a small bracket, or the
spring itself may be formed to receive the rubber block, having a neck in the
middle to lie upon the spring or bracket thereon so that it can accommo-
date itself freely to the roller, and can easily be removed and replaced. The
rubber block may have rubber material on one or more sides, and be capable of
being turned over to a fresh side.
The bush or bearing applying pressure to the pressing axles is set into the
hanger or hook in such a way as to be capable of swinging freely in the plane of
pressure so as to accommodate itself to inequalities in the pressing roller, and
still preserve a full bearing upon the axle. The bush though free to move is
prevented from falling out of the hook or hanger.
Conductors for the slivers entering gills at the back of preparing machinery
are provided upon a bar immediately behind the rising of the fallers, the said
conductors may consist of gaps cut out a suitable breadth in the bar to guide and
confine such slivers entering the gills, or separate conductors may be attached
to said bar, and be either adjustable or fixed permanently thereto. The bar may
be secured in position with screws or otherwise to the back roller, or bottom
slide, or to some other part of the machine with facility for ready removal, such as
by lifting out of a slot or catch.

Improvements in Drawing and other Preparing Machinery for
Textile Fibres.
We, CHARLES DRENNAN, of Battenberg Street, Belfast, Foreman Fitter, JAMES
HEANEY, of Clonard Street, Belfast, Preparing Overlooker, ARTHUR WILSON MET-
CALFE, of Grove Mill, Belfast, Flax Spinner, and JAMES MACKIE, of the Albert
Foundry, Belfast, in the County of Antrim, Ireland, Machine Maker, 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 improvements in the supports for the rubbers of front
rollers in the bearings or gibs for the axles of the front pressing rollers, and in a
sliver conductor placed at the back of the fallers.
It will be fully described with reference to the accompanying drawings in
which sufficient of a flax drawing frame is shown to illustrate the invention.

At
We support the rubbers A which press against the under side of the drawing
roller B by means of a bar C fixed parallel to the roller, and attached to the
under surface of the bottom slide D or other suitable part of the frame. The
bar C runs longitudinally of the machine and carries a number of springs C
attached to it at intervals, which extend towards the front of the machine.
the extremity of each spring C¹ is fitted a small bracket c upon which the
rubber A rests. Instead of the bracket c fitted to the end of the spring,
the spring may at its end be so formed as to provide a support for the rubber. The
rubber block A is preferably made with a neck a in the centre, so as to engage
with two roller bosses, the neck a resting upon or engaging with the spring
bracket, so that the rubber may readily accommodate itself to the bosses of
the roller B. The rubber block A will be easily removed and replaced, and may
be made either with one side or with two, three or more sides to receive the
rubbing material, and be capable of being turned round about its axis in the
spring bracket c.
The bottom slide 1), the top slide 1' the back rollers E and E¹ and the jockey
roller Fare of the ordinary construction.
The gib or hanger G is constructed with the bush or bearing H by which pres-
sure is applied to the axle of the pressing roller K fitted so as to be capable of
swivelling freely in the plane of pressure, so as to accommodate itself to any
inequality in the sizes of the bosses of the pressing roller K, and preserve a full
bearing upon the axle k. The bearing or bush H is formed with an inclined or

page_text: curved top, and is fitted loosely into the gib head or hanger G, the under
surface of which rests upon it. At either end the bush H is provided with
trunions which fit into grooves or slots g in the gib head upon which it can
swivel or rock, and is held in position therein by pins or rivets g¹ driven across
the slot after the bush is inserted (as shown in detail in Figs. 3, 4 and 5.) In
an alternative arrangement the bush H may be held in position by a pin or
screws, running longitudinally through the bush H, the ends passing into holes
drilled in the gib heau G, this pin also forming a pivot for the bush H to rock
or swivel upon (as shown in detail in Figs. 6, 7 and 8). Or the bush H may be
held in position by a projection H¹ passing up through a hole in the gib head G,
with a pin inserted therein on the outside (as shown in detail in Figs. 9
and 10). Or the projection H¹ may be screwed either externally or internally
and secured by a nut or set screw.
Between the roller E (to the front of the back set of rollers) and the rising
faller L, we place a sliver guide or conductor to direct the sliver straight into
the gills on the fallers L, to prevent any lateral displacement of the fibres. The
guides or conductors M are attached to or secured upon a bar N, which is
bolted to the back rulers 0 or to the bottom slide C or to any other convenient
part of the framing. The sliver guides or conductors M are preferably movable
and capable of being adjusted opposite the gills as in Figs. 11 and 12, or they
may be formed of gaps m cut out of the bar N of suitable breadth to guide and
confine the slivers entering the gills.
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:-
1. The combination with the under rubbers of the front roller of a bracket
upon which the rubber rests, supported by a spring attached to a bar running
longitudinally of the machine, substantially as described.
2. A gib or hanger for the front pressing roller constructed with a loose bush
or bearing capable of swivelling therein to accommodate itself to inequalities of
the pressing roller, substantially as described.
3. The combination with the gib or hanger G of a bush H formed with inclined
or curved top and trunnions h fitting into grooves in the gib head, substantially
as described and shown.
4. The combination with the gib or hanger G of a bush H capable of swivelling
therein, held in position by a pin, substantially as described and shown with
reference to Figs. 6, 7 and 8 or Figs. 9 and 10.
5. A sliver guide or conductor placed between the back roller E and the rising
faller to guide or direct the sliver to the gills, substantially as described and
shown.
