PROVISIONAL SPECIFICATION.
Improvements in "Nap" Raising Machines.
I, CHARLES EDWARD MOSER, of Aix-la-Chapelle, Germany, and the Queen's
Hotel, Leeds, England, Engineer and Machine Maker, do hereby declare the
nature of this invention to be as follows:-
My invention has reference to certain improvements in " nap" raising machines.
According to my said improvements I employ a series of raising or napping
rollers carried in suitable bearings upon the framework of the machine. Each
of the said series of raising or napping rollers may be arranged separately, or
the said series may be arranged in pairs, in threes, or other suitable collocation.
Interposed between the said raising or napping rollers are plates, heated by
steam or hot air, for heating the cloth while passing round and in contact with
the raising or napping rollers. The bearings carrying the said raising or napping
rollers are adjustable or movable upon the said framework by means of screws
or their equivalent so that the raising or napping rollers may be brought more
or less into contact with the cloth, as required.
The machine is driven by means of a shaft deriving its motion from a counter-
shaft or other shaft or motor. The said driving shaft carries pulleys from which
pass belts to pulleys upon the journals of the raising or napping rollers, the said
belts pass over and under, and vice versa, the said pulleys of the raising or napping
rollers depending upon the arrangement of the said rollers, as previously referred
to, thereby causing each alternate raising or napping roller to revolve in the
opposite direction to that preceding it so that the fabric is teasled against the nap
and with the nap simultaneously. Or other suitable motion may be given to the
said raising or napping rollers.
The cloth is passed into the machine and taken off by guide rollers and parts
connected therewith.

Improvements in "Nap" Raising Machines.
:
I, CHARLES EDWARD MOSER, of Aix-la-Chapelle, Germany, and Queen's
Hotel, Leeds, England, Engineer and 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:-
My invention has reference to certain improvements in "nap" raising machines.

page_text: According to my improvements I employ a series of raising or napping rollers A
carried in suitable bearings B upon the framework C of the machine. The said
series of raising or napping rollers are arranged in pairs or groups, as shown in the
drawings annexed.
Interposed between the said raising or napping rollers are plates D (heated by
steam or hot air) for heating and guiding the cloth or fabric E while passing
round and in contact with the raising or napping rollers A. The said plates D are
hollow inside and connected to the steam or hot air supply D₁ (for heating the
roller D2) at one end, and open at the other end to allow of the removal of the
condensation, when steam is used.
The bearings B carrying the said raising or napping rollers are adjustable or
movable upon the said framework by means of screws F (or their equivalents) so that
the raising or napping rollers A may be brought more or less into contact with the
cloth as required. For this purpose the said screws F are fastened to plates F¹ by
nuts F and screw through bosses or blocks F3. F4 are slots through which project
bolts F, which are tightened or slackened in the slots by nuts Fo.
The machine is driven by means of shaft G deriving its motion from a counter-
shaft or other shaft or motor.
The said driving shaft G carries pulleys H and H' from which pass belts J
and J to pulleys K upon the journals of the raising or napping rollers A. The
said belts J and J' pass over the pullevs of the raising or napping rollers so as to
cause one series or group of raising or napping rollers to revolve in the opposite
direction to the other, so that the fabric is teaseled against the nap and with the
nap simultaneously. Or one raising or napping roller in each pair or group may
be driven from one side of the machine, and the other roller in each said pair or
group may be revolved from the roller driven as aforesaid, by connecting them by
means of pinions, or pulleys and cross-belts, or other such means, the other end of
the rollers will therefore simply turn in their bearings. Or the said rollers may
be driven in any other suitable manner.
The speed of one of the said rollers (relatively to the other) may be varied by
altering the size of the pulley used.
The cloth is passed into the machine and taken off by guide rollers and parts
connected therewith, which will be readily understood by those skilled in the art
from the drawings.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed declare that what I
claim is :-
A nap raising machine having raising or napping rollers arranged in pairs or
groups in bearings which are adjustable or movable upon a stationary frame so
that the said raising or napping rollers may be brought more or less into contact
with the fabric, and which said rollers are driven so as to act against the nap
and with the nap simultaneously, as shown and described.
