Apparatus through which Successive Lengths of Cloth or
Fabrics have to be Passed.
I, EBENEZER MARSHALL of 22 New York Street Chorlton-upon- Medlock
Manchester in the County of Lancaster Mechanical Engineer, 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 machinery or apparatus through which successive
lengths of cloth or fabrics have to be passed from rollers as for example in finishing
bleaching dyeing printing and similar processes and has for its object to enable the
successive lengths to be passed continuously without stopping the machine or
apparatus at the end of each piece or batch.
These Improvements consist in the adaptation or arrangement to or with
Calenders or other apparatus or machines through which successive lengths of cloth
or fabrics have to be passed, of an apparatus by means of which the successive
lengths of fabric may be joined or connected together without stopping the machine
and in the construction of the joining or connecting apparatus.
And in order that this invention may be more readily understood and carried
into practical effect I have hereunto appended a sheet of Drawings having similar
parts or details in each of the figures indicated by similar letters and reference
being hereinafter had thereto.
Fig. 1. represents the apparatus in end elevation and Fig. 2 in side elevation as
applied to or arranged with an ordinary Calender. A similar arrangement may be
adopted with machinery or apparatus other than a Calender or the joining or
connecting apparatus may be arranged level with or below the Calender or other
machine or in any other convenient position instead of above as represented in the
Drawings.
than c
The joining or connecting apparatus consists of a framework or bearings for the
shaft a upon which are mounted the 3 pulleys b. c. d, d having a greater diameter
From the shaft a is driven the shaft e upon which are mounted the
2 pulleys ff¹ either of which is capable of driving the shaft e when connected by
the clutch g. The pulleys ff¹ may be of equal diameter. Upon the shaft e. is
also mounted the roller h and above it a smaller roller i. On a lower level and in

page_text: front of roller his fixed the table or board k to which may be attached the
sewing machine j. Below h and k are brackets carrying bearings for the spindles
of the cloth rolls. These bearings consist of slots or grooves closed at the bottom
by plates or blocks m which are capable of being removed by the handles n but
are ordinarily kept in position by spiral springs o or their equivalent. In front of
the bearings are two rails y upon which the ends of the spindles of the following
rolls may rest and below the bearings are two inclined planes p. Behind the
apparatus may be placed inclined bars or board r upon which the cloth is delivered
and beyond r there may be placed a frames carrying staves between which the
cloth may be passed to remove creases. From s the cloth t t passes to the Calender
or other machine or apparatus. The pulley b is driven from the calender or other
apparatus so that when this machine is stopped the motion of the roller h is also
arrested. The pulleys c. d and ff¹ are connected respectively by endless bands
or belts.
The operation of the apparatus is as follows-Let it be supposed that a length of
cloth is being passed through the apparatus as represented in Fig. 2. Here u is
part of a roll of unfinished cloth which is being unwound by h and i and delivered
on whence it is drawn by the Calender and finally wound on the roller w.
During this part of the operation the roller h is driven by the pulleys c. f. and the
rate of delivery of the cloth upon r corresponds with the speed at which it passes
through the calender or other machine, At the same time the following roll of
cloth is placed with its spindle on the rails y. When only a few yards of cloth
remain upon u the clutch g is moved over to engage the pulley f¹ whereupon the
roller h is driven at an increased speed and the cloth accumulates upon r.
Just
before the end of the cloth leaves u the roller h may be stopped by disengaging the
clutch g from f¹. The ends of t and of the roll x are then placed upon k where
they may be lightly stitched or otherwise joined together by the sewing machine
or by other usual or convenient means. By this time the accumulation of cloth
upon will probably have become nearly exhausted but if not then as soon as this
is the case, the clutch g is caused to engage with the pulley f and the cloth is
delivered at its normal speed from the roll x which has meanwhile taken the place
of by the following operation: As soon as the ends of t and have been
connected the attendant withdraws the blocks m by means of the handles n
whereupon the roller u drops upon the inclined rails p and slides forward out of
the way. The roll x is then pushed forward along y until its spindle drops into
the bearings previously occupied by the spindle of u The ends of the cloth or
fabric are lightly joined or connected together in order that the attendant at w
when a joint approaches may readily break it and pass the disconnected end
issuing from the Calender or other machine around another roller as for example w¹
Bo that the successive lengths may be wound upon separate rollers.
By these Improvements a considerably increased out put is obtained from each
Calender or other machine or apparatus to which it may be applied since it may
be worked continuously without stopping at the end of each length.
It will be understood that we do not limit ourselves to the precise details and
arrangement herein before described and illustrated on the accompanying drawings
as the same may be considerably varied without departing from our invention, and
further that although we have represented these Improvements as applied to a
Calender we may apply them to any other machine or apparatus through which
successive lengths of cloth or fabric are required to pass from rollers, and finally
that we do not claim any portion of the Calender as part of this our Invention.
Having now particularly described and ascertained the nature of this my
said Invention and in what manner the same is to be performed I declare
that what I claim is :-
(1.) The adaptation to or arrangement with a Calender or other machine or
apparatus through which successive lengths of cloth or fabric have to be passed of
an apparatus by means of which the end of each length is delivered at a higher

page_text: rate of speed and temporarily accumulated so as to permit the following length to
be joined thereto without arresting the motion of the Calender or other machine or
apparatus, substantially as herein before set forth and described.
(2.) The combination and arrangement of the shaft a the pulleys c d the shaft e
the pulleys ff¹ the clutch g the rollers hi the table k with the removable
bearings 1. m the rails y and the inclined planes or rails p, substantially as and
for the purposes herein before set forth and described and as illustrated on the
accompanying sheet of Drawings.
(3.) The combination of the apparatus consisting essentially of the parts specified
in the preceding claim, with the inclined planer and the frame and staves 8,
substantially as hereinbefore described and set forth and as illustrated on the
accompanying sheet of drawings.
