I TITUS SALT, a, Director of "Sir Titus Salt Bart. Sons and Company Limited'
of Saltaire in the County of York Manufacturer, do hereby declare the nature of
my invention for IMPROVEMENTS IN APPARATUS USED IN, SHEARING OR CUTTING
THE PILE OF PILE FABRICS to be as follows:-
The present invention has reference to certain improvements in machinery for
use in shearing or cutting the pile of pile fabrics to an even surface and these
improvements are adapted to be used in combination with apparatus such as is
described in the provisional specification accompanying my application for Patent
dated February 9th 1885 N° 1760 or a modification or adaptation thereof in part
or whole.
In the present improved apparatus the pieces of pile fabric, either in endless
band form, or with unconnected ends, or, only connected into a long piece, pass
over a supporting bar having a narrow edge which presents the pile surface
successively to the cutting instrument, as the piece travels on, in order to its being
shorn evenly; and as the stretched piece passes on towards the point where the
shearing takes place it is submitted to a brushing instrument, the brushing being
generally effected by a revolving roller brush; but it may be a band of brushes on
a belt operating across the piece horizontally or in other direction, the piece being
held distended by means of a roller, or rollers clothed with card surface, for the
better hold on the piece. A tray or collecting box placed in front of the brushes
and somewhat below serving to catch the severed pile and prevent its becoming
again mixed with the unsevered pile. When shorn the piece is conducted past a
rotating beam provided with blades to a travelling scray, or table of slats or bars,
or a moving apron carried by suitable distending axes intermittently operated by
suitable gearing so that the piece in even folds becomes arranged upon and is
carried along by this travelling surface until at the opposite side it becomes lifted
smoothly and regularly and is caused to pass over a suitable roller to a beam;
thence partially around, or over a guiding beam or roller, thence partly around
another roller clothed with card surface and upwards to the narrow edged support,
with which this description of the course of the piece commenced passing the
brush.

page_text: Brushing means act on the pile surface of the piece on its way to the cutting
point to raise the pile ready for the cutter and remove extraneous matters.
The blade or bar which supports the piece and presents the edge of pile to the
cutter is lowered during adjustment and raised for the cut.
•
The intermittent motion to the supports of the travelling surface may con-
veniently be attained by applying a ratchet wheel to the axis of the rear support
(operated by a click, or driver, conveniently in two divisions operating alternate
teeth as the driver, or double driver) and by the respective reciprocations of the
click or driver the roller or support is turned and traversing of the scray from front
to rear takes place. The clicks may be carried by a lever arm centred to the rear
roller this lever arm at its outer end being connected by a.rod or arm to and so as
to rotate (as on a crank pin) around the face of a disc applied to the axis of one of
the card clothed distending rollers-the pin on which this arm or link turns being
fitted to and held in a groove or slot extending from the centre to the periphery of
the disc, with capability of adjustment of the pin and consequently of the throw or
inotion imparted to the rod and to the click operating the ratchet and thereby the
speed of the scray's traverse. The scray is carried by preference on groove pulleys
which engage projections on the inner face of the scray and thereby preserve
correct relation.
Upon the axis of the front card clothed distending roller is applied a concentric
shoulder or pulley adapted to be engaged and frictionally retarded by means
of a strap passed partly around it and having its ends secured the one to the
fixed portion and the other to the loose portion weighted of an articulated or
jointed arm.
The front portion of the machine before travelling apron or scray is protected by
a shield or fence board and the rear side may be so if desired.

Pile of Pile Fabrics.
I TITUS SALT, a Director of "Sir Titus Salt Bart. Sons and Company Limited"
of Saltaire in the County of York 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:-
The present invention has reference to certain improvements in machinery for
use in shearing or cutting the pile of pile fabrics to an even surface and these
improvements are adapted to be used in combination with apparatus such as is
described in the specification accompanying my application for Patent dated
February 9th 1885 N° 1760 or a modification or adaptation thereof in part
or whole.
In the present improved apparatus the pieces of pile fabric, either in endless
band form, or with unconnected ends, or pieces only connected into a long piece,
pass over a supporting bar having a narrow edge which presents the pile surface
successively to the cutting instrument, as the piece travels on, in order to its being
shorn evenly; and as the stretched piece passes on towards the point where the
shearing takes place it is submitted to a brushing instrument, the brushing being
generally effected by a revolving roller brush; but it may be a band of brushes on
a belt operating across the piece horizontally or in other direction; the piece being
held distended by means of a roller, or rollers clothed with card surface, for the
better hold on the piece. A tray or collecting box placed in front of the brushes
and somewhat below serving to catch the severed pile and prevent its becoming
again mixed with the unsevered pile. When shorn the piece is conducted past a
rotating beam provided with blades to a travelling scray, or table of alats or bars,
or a moving apron carried by suitable distending axes intermittently operated by
suitable gearing so that the piece in even folds becomes arranged upon and is
carried along by this travelling surface until at the opposite side it becomes lifted
smoothly and regularly and is caused to pass over a suitable roller to a beam;
thence partially around, or over a guiding beam or roller, thence partly around
another roller clothed with card surface and upwards to the narrow edged support,
with which this description of the course of the piece commenced passing the
-brush.
Brushing means act on the pile surface of the pièce on its way to the cutting
point to raise the pile ready for the cutter and remove extraneous matters.
As already described in the aforesaid specification the intermittent motion to the
supports of the travelling surface may conveniently be attained by applying a
ratchet wheel to the axis of the rear support (operated by a click, or driver,
conveniently in two divisions operating alternate teeth as the driver, or double
driver) and by the respective reciprocations of the click or driver the roller or
support is turned and traversing of the scray from front to rear-takes place. The

capability of adjustment of the pin and consequently of the throw or motion
imparted to the rod and to the click operating the ratchet and thereby the speed

DESCRIPTION OF THE DRAWINGS.
The figure shews a sectional side elevation of the machine. The dotted lines A
indicate the course taken by the pile fabric to be shorn or cut. B indicates the
main framing, a is the cutting instrument revolving in the direction of the arrow
and formed of cutting blades a on a suitable support a' as is well understood. 6 is
a supporting bar over which the sheet of fabric passes in the direction of the arrows
and by which it is presented to the cutters ac is a revolving brush turning in
the direction of the arrow and adapted to brush the pile of the fabric A as it is
drawn past it, the fabric A being kept distended: between the edge of the bracket d
and the rotating cylinder e which being clotbed with card cloth or suitable similarly
holding material serves to hold and retard the passing fabric A as that roller e is
itself retarded in its revolution by means of a break strap or similar means e¹
'passing around its axis e³, said band e¹ being connected to the articulated weighted
arm ee whereby pressure is exerted to retard the roller e. Direction is given to
the sheet of fabric A for its passage partly around the card roller & by its passing
partly around the guide roller f g is a tray or collecting vessel for collecting
severed portions of pile removed by the brush c. h is a distending and guiding
bar over which the fabric A passes as it is drawn up from the scray or travelling
surface which brings it in folds from front to back of the machine as already
described fully in my said former specification. j is a roller or cylinder covered
with card or similar holding material around which partly the fabric A passes and
is drawn upon thereby. From this cylinder the fabric passes to and is acted upon
by the revolving guide roller k and thence is delivered to the scray i for renewal
of the operation or completing of the treatment. Z is a shield or fence rearward of
the machine:.
The blade or bar 6 which supports the piece A and presents the edge of pile to
.the cutter a¹ is lowered during adjustment and raised for the cut.
.In the apparatus described it will be seen that with the exception of the roller f
none of the supporting parts come in contact with the face of the pile of the fabric.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is:
1. In machinery for shearing, cutting or trimming the ends of the pile of pile
fabrics. The use of a roller covered with card surface for the purpose of retarding
the cloth as it is being drawn through the machine substantially as and for the
purpose set forth,

page_text: 2. The method of retarding the card roller by means of a strap and lever as and
for the purpose set forth and shown by the drawing.
3. In machinery for shearing cutting or trimming the ends of the pile of pile
fabrics the use of a tray or trays or collecting vessel or vessels to collect the
severed pile or dust which is removed from the cloth by the brushing means as
set forth.
4. In machinery for shearing cutting or trimming the ends of the pile of pile
fabrics the combination or arrangement of parts for distending the fabric whose
pile is to be cut as set forth.
5. The combination or arrangement of parts of machinery for shearing or cutting
the pile of pile fabrics set forth herein and shown by the accompanying drawings.
Dated this 14th day of July 1886.
