Improvements in Fulling Machines.
I, HENRY GROSSELIN of 1 Boulevard St. Denis, Paris, France, Machine Builder, do
hereby declare the nature of this invention to be as follows:-
This invention has reference to fulling machines and has for object to prevent
entanglement or disarrangement of the pieces of cloth in the trough of the machine
and at the same time obtain a more rapid and more regular fulling.
In machines of the ordinary construction the stocks or mallets, generally two, are
raised one after another; the result is that the beating action on the cloth is given
alternately at the right and the left. The cloth being thus pushed by alternate blows
or pressures from one side to the other becomes disarranged in the trough; this
necessitates frequent handling and causes irregularities in the fulling.
The
In the machines, constructed according to my invention, there are, according
to one modification, three mallets, of which the middle one occupies a working
width equal to or slightly less than that of the other two combined.
action of the three mallets is produced by a cranked shaft arranged so that
the middle mallet is at the bottom of its travel when the two outside mallets
are both at the top and vice versa. It will be readily understood that with this
arrangement the action of the mallets is exerted on the cloth in a symmetrical manner
alternately in the middle and at the two sides of the trough. The width of the two
outside mallets being the same their action is equal and the fabric does not get
displaced during its movement in the trough. Further, the fulling is more rapid on

another.
Instead of the mallets being worked by cranks they can be worked by cams which
first raise the mallets and then allow them to fall by their own weight. The cams in
this case are arranged on a shaft so as to lift and release the mallets in the order
already explained.
According to another modification I employ two mallets or beaters each of which
covers the whole width of the trough. These mallets are placed one above another
and work one after the other; the lower one pushing the cloth and causing it to turn
and the upper one completing the work and fulling with a strong pressure without
causing any displacement of the cloth. More than two mallets can be similarly.

The machine may also have say four mallets, two of them alternating with the other
two, that is to say, mallets 1 and 3 will alternate with mallets 2 and 4.

COMPLETE SPECIFICATION..
Improvements in Fulling Machines.
I, HENRY GROSSELIN of 1 Boulevard St. Denis, Paris, France, Machine Builder, 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 has reference to fulling machines and has for object to prevent
entanglement or disarrangement of the pieces of cloth in the trough of the machine
and at the same time obtain a more rapid and more regular fulling.

page_text: In machines of the ordinary construction the stocks or mallets, generally two, are
raised one after another; the result is that the beating action on the cloth is given
alternately at the right and the left. The cloth being thus pushed by alternate blows or
pressures from one side to the other becomes disarranged in the trough; this
necessitates frequent handling and causes irregularities in the fulling.
In the machines constructed according to my invention there are according to one
modification which is represented in Figures 1 and 2. of the annexed drawings three
mallets C, C, C³ of which the middle one occupies a working width equal to or
slightly less than that of the other two C¹ and C³ combined. The action of the three
mallets is produced by a cranked shaft A and connecting rods B', B', B' arranged so
that the middle mallet C is at the bottom of its travel when the two outside
mallets Care both at the top and vice versa. It will be readily understood that
with this arrangement the action of the mallets is exerted on the cloth in a symmetrical
manner, alternately in the middle and at the two sides of the trough. The width of
the two outside mallets being the same their action is equal and the fabric does not get
displaced during its movement in the trough. Further, the fulling is more rapid on
account of the division of the surface upon which the mallets act: If desired five
mallets can be used instead of three, three of them working on one axis of rotation and
two on another.
Instead of the mallets being worked by cranks they can be worked by cams which
first raise the mallets and then allow them to fall by their own weight. The cams in
this case are arranged on a shaft so as to lift and release the mallets in the order already
explained.
i
According to another modification which is represented in Figures 3 and 4 I employ
two mallets or beaters CC each of which covers the whole width of the trough:
These mallets are placed one above another and work one after the other by the action
of the cranked shaft A and connecting rods B B; the lower mallet pushing the
cloth and causing it to turn and the upper one C' completing the work and fulling with
a strong pressure without causing any displacement of the cloth. More than two
mallets can be similarly superposed.

My improved machines may also have say four mallets two of them alternating with
the other two, that is to say mallets 1 and 3 will alternate with mallets 2 and 4.
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.::
1. In a fulling machine three mallets or beaters placed side by side the middle one
being wider than the other two and being worked alternately there with so that it is at
the bottom of its travel when the others are at the top and vice versa, substantially
as hereinbefore described and represented in Figures 1 and 2 of the annexed
drawings.
.
.
2. In a fulling, machine, two or more superposed mallets or beaters worked one
after another and each of them covering the whole width of the trough, substantially
as herein before described and represented in Figures 3 and 4 of the annexed
drawings.
