IMPROVEMENTS IN MACHINERY USED IN SHEARING OR CUTTING THE PILE OF PILE FABRICS

I TITUS SALT a Director of "Sir Titus Salt Bart., Sons & Company, Limited" of
Saltaire in the County of York Manufacturer do hereby declare the nature of my
invention for IMPROVEMENTS IN MACHINERY USED IN SHEARING OR CUTTING THE
PILE OF PILE FABRICS to be as follows:-
:-
These improvements relate to machinery for use in shearing or cutting the ends
of the pile of pile fabrics to substantially an even length and particularly to means
for conveying the piece to be shorn from one side or end of the machine to the
other during shearing or otherwise, without creasing, or damage thereto.
For this purpose I arrange my improved machinery so that the piece of pile
fabric or pieces of pile fabrics, joined as usual into an endless band by connecting
the ends of the piece or pieces or the ends of the piece may be unconnected, may
be passed under the operation of the cutting or shearing means for the making
even of the pile, and as the portion of the piece emerges from this shearing it is
received onto a travelling scray or apon or travelling surface adapted to convey
the successive portions of the endless piece deposited by the operation of the
machinery from the delivery to the receiving end of the shearing means gradually
in such a manner as not to crease or damage it and avoid the loss of time and
labor required to push the piece along, when, as is the practice, the endless piece is
permitted to accumulate at the front of the machine and the operator pushes it at
intervals underneath the machine where it is supported on boards or stillages
placed there for the purpose and from which it is drawn as required to enter at
the back of the machine.

Improvements in Machinery Used in Shearing or Cutting the
Pile of Pile Fabrics.
I TITUS SALT a Director of "Sir Titus Salt Bart. Sons & Company Limited" of
Saltaire in the County of York Manufacturer do hereby declare the nature of my
invention for IMPROVEMENTS IN MACHINERY USED IN SHEARING OR CUTTING THE
PILE OF PILE FABRICS and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement,:-
In machinery used in shearing or cutting the pile of pile fabrics such as velvet
or plush especially it has been the general practice to allow the velvet or other
fabric being treated to pass down from the part delivering it from the cutting parts
to the front of the machine where it is permitted to accumulate and the attendant
from time to time pushes it along to the underneath part of the machine where it
is supported on boards or stillages placed there for the purpose and from whence
the fabric is drawn upon to cause it to enter at the back of the machine for
treatment or repeated treatment but this arrangement exposes these materials such
as velvets and the like to creasing and damage besides causing loss of time and
expenditure of labor in order to effect the repeated pushings of the piece from front
to back below the machinery.
The object of the present invention is to effect this transfer of the fabric
regularly and automatically from one side of the machine to the other by
mechanical means without necessitating the constant attention of the attendant
for the purpose as heretofore and to effect the object in a better manner avoiding
creasing or damage to the piece in transit.
In carrying out my invention my improved machinery is arranged so that the
piece of pile fabric or pieces of pile fabrics, joined as usual into an endless band
by connecting the ends of the piece or pieces or the ends of the piece may be
unconnected, may be passed under the operation of the cutting or shearing means
for the making even of the pile and as the portion of the piece emerges from this
shearing it is received onto a travelling scray or apron or travelling surface adapted
to gradually convey the successive portions of the piece or endless piece deposited
by the operation of the machinery from the delivery, to the receiving end of the
sbearing means.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a side section taken on a line passing through the machine from
front to back. Figure 2 side view of the means adapted to give to the scray its
progressive or step by step motion from front to back by operating the front
axis H. Figure 3 is a front view of this device and part of the roller B and of 3
this Figure 4 is a corresponding plan view a indicates generally the main framing
of the machine, A is the cutter, which shears the fabric. B is a roller or cylinder
clothed with card or similarly holding surface adapted to put a drag on the
fabric F to draw it along continuously and keep it tightly stretched between the
roon of th

page_text: after passing the revolving guide roller B¹ it is delivered to the scray C in regular
folds which scray being continuous and supported on front rollers H and back
rollers H¹ which are caused to revolve intermittently the fabric F is conveyed
along with it until arriving at the other end it receives the draught of the
ruller B and having first been passed over an adjustable roller Z supported on the
standard Z which roller Z admits of the point at which the piece of fabric leaves
the scray or travelling apron so as to compensate for the variations in the length
of the pieces whilst the nicer adjustments of the speed of the travel of the scray or
travelling surface are effected by the movement of the crank pin N to or from the
centre of the disc O passes up to and over the beam D under another roller or
beam D' and over another beam D2 so arranged as to put a drag or tension on the
fabric to strain it level and it thence passes under a guide rod or roller D³ and
over a roller D under a guiding roller E¹ to the blade A¹ over a bar E³ undergoing
a brushing operation as it passes by the revolving brush E..
The apron or scray C stretched upon the axes H H is constructed and operated
as follows.
c are a series of slats or wooden bars connected to supports, belts, bands or
sheet c¹ by rivets or screws c³ having large heads with flat and substantially broad
underheads so that when leather for the band c¹ is used a good and secure hold is
obtained and these heads I utilize to form guides for securing the correct traverse
of the scray or travelling surface by their engaging or lying in the grooves h³ sunk
in the belt or band supporting pullies h¹ carried by the axes H H¹ and upon the
end of one of these axes H is applied a ratchet wheel I engaged by a click K (or
duplicate click one click taking one and the other another tooth) as the click is
lifted and lowered by the oscillating lever L which lever is centred on the shaft H
at L¹ and is connected at L' to one end of the connecting rod M which engages
at M the pin N which is carried in the undercut slot O¹ formed in the face of the
revolving disc O carried on the shaft B2 of the tension roller B and driven thereby.
This slot O¹ running from centre to a peripherical line on the face of the disc O
enables the pin N which is by a sliding adjustment fixed in it to be adjusted to
give a greater or less throw or extent of motion to the click K and thereby to the
roller operating the scray or travelling surface C and so regulate the speed of travel
of the fabric and its supply to the rear side of the machine.
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 a mechanically operated carrier, travelling surface or scray for carrying the
fabric being operated upon from one side or end to another side or end of a machine
substantially as set forth.
2. The construction and arrangement of the parts of travelling surfaces, carriers
or scrays and means of operating the same, for conveying plusli, velvet or other
pile fabrics from one side to another of machinery used in shearing, trimming or
cutting the pile of such fabrics substantially as set forth.
