PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Cutting Piled Fabrics.
I JOHN JAMES MANN of Chatham Buildings Circus Street Manchester in the
County of Lancaster Electrician do hereby declare the nature of this invention to be
as follows:-
This invention relates to improvements upon the apparatus for cutting piled fabrics
for which Letters Patent No. 16996, dated 10th December 1887 were granted to James
Hoyle Smith, Andrew Goddard, Lloyd Higginbottom and Thomas Mannock, and
especially to that part of such apparatus which relates to the carrying of the cloth
backwards and forwards past the knife as described in the Specification of such Letters
Patent with reference to Fig. 4 on the drawings accompanying the same, the objects
of my invention being first to shorten the traverse and diminish the speed of the
carriage and hence diminish the room occupied by the machine and at the same time
to obtain a corres¡ onding increase in the length of traverse of the cloth to be cut, and
secondly to improve the means for traversing the carriage whereby it is kept square
and all tendency to oscillate is obviated.
For this purpose instead of having only one roller at each side of the carriage and
one roller at each end of the machine I propose to have two or more rollers for
example say three rollers at each side of the carriage a corresponding number of
rollers at each end of the frame, and the cloth which is held by the two tightening
rollers as before passes from one tightening roller alternately round the rollers at one
side of the carriage and at the same end of the frame, then over the two rollers g. h.
at the top of the frame a where cutting of the pile takes place, and then alternately
round the rollers at the other end of the machine and the rollers on the same side of
the carriage to the other tightening roller and the action will be then the same as that
of a multiple sheaved pulley tackle, so that a shorter and slower traverse to and fro of
the carriage will impart a longer traverse of the cloth to be cut.
For moving the carriage to and fro instead of having one rope wheel only I have
two (one at or near each side of the frame) and I employ an endless rope which first
passes round one wheel then round one or more guide pulleys at one end of the frame,
then round two pulleys on the same level on the carriage back again over one or more
guide pulleys on the same end of the frame, thence round the other rope wheel and
then round the same arrangement of pulleys at the other end of the machine and back
again to the first rope pulley.
The carriage, instead of having a central guide only, has a clip or slide upon each
side running upon a rail or rod.
By this arrangement the carriage is kept always square and all tendency to oscillate
is obviated.

Improvements in Apparatus for Cutting Piled Fabrics.
I JOHN JAMES MANN of Chatham Buildings Circus Street Manchester in the
County of Lancaster Electrician 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 upon the apparatus for cutting piled fabrics
for which Letters Patent No. 16996 dated 10th December 1887, were granted to James
Hoyle Smith, Andrew Goddard, Lloyd Higginbottom and Thomas Mannock, and

page_text: especially to that part of such apparatus which relates to the carrying of the cloth
backwards and forwards past the knife as described in the Specification of such
Letters Patent with reference to Fig. 4. on the drawings accompanying the same,
the objects of my invention being to shorten the traverse and diminish the speed
of the carriage, and hence to diminish the room occupied by the machine and at
the same time to obtain a corresponding increase in the length of traverse of the
cloth to be cut and secondly to improve the means for traversing the carriage
whereby it is kept square and all tendency to oscillate is obviated.
The nature of my invention and the manner in which the same is to be performed
or carried into practical effect will be readily understood on reference to the annexed
sheet of drawings and the following explanation thereof.
Fig. 1. is a partial longitudinal section and Fig. 2 a sectional plan view of so much
of a pile-cutting machine (of the construction previously referred to) as is necessary
to illustrate the application of my invention thereto.
a is part of the framing of the machine and is the travelling carriage.
Instead of having only one roller at each side of the carriage and one roller at each
end of the machine I propose to have two or more rollers c and c' (for example say
three rollers) at each side of the carriage band a corresponding number of rollers d
and d' at each end of the frame a, and the cloth which is held by the two tightening
rollers e, el as before passes from one tightening roller e alternately round the rollers
at one side of the carriage band at the same end of the frame a, then over two
rollers and at the top of the frame where the cutting of the pile takes place,
and then alternately round the rollers at the other end of the machine and the
rollers c¹ ou the same side of the carriage to the other tightening roller e³, as shown by
the dotted lines and the action will be the same as that of a multiple-sheaved pulley
tackle so that a shorter and slower traverse to and fro of the carriage will impart a
longer traverse to the cloth to be cut.
For moving the carriage to-and-fro instead of having one rope wheel only I have
two rope wheels fand f(one at or near each side of the frame) and I employ a rope i
one end of which is fastened to the rope wheel f round which it is passed; it then
passes round a guide pulley f*, at one end of the frame, and thence to two carrier
pulleys on the same level on the carriage and back again over another guide
pulloy, on the same end of the frame, thence to the other rope pulley to which
it is fixed. A similar arrangement of rope and pulleys f*, and is provided at the
other end of the machine, the rope being coiled round the rope pulleys in the
reverse direction.
Or an endless rope may be employed passing round the pulleys and rope wheels in
a similar way but I prefer the arrangement above described. The carriage c instead of
having a central guide only, has one or more clips or slides m, upon each side running
upon a rail n or a rod. By this arrangement the carriage is kept always square, and
all tendency to oscillate is obviated.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
In apparatus for cutting pile fabrics such as has been herein referred to, the use of
a travelling carriage for imparting the two and fro motion to the cloth, such carriage
being provided with two or more sets of rollers and operating in combination with
two or more stationary rollers at each end of the frame in such manner that the cloth
being led backwards and forwards over the said rollers, has a greatly increased trave
imparted to it where it passes under the knife as compared with the travel of the
carriage itself, substantially as described.
