page_text: LETTERS PATENT to John Smith, of Cheetham, in the City of
Manchester, Bleacher, Dyer, and Finisher, for the Invention
of "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR BEETLING WOVEN
FABRICS."
PROVISIONAL SPECIFICATION left by the said John Smith at the
Office of the Commissioners of Patents, with his Petition, on the
30th April 1872.
I, JOHN SMITH, of Cheetham, in the City of Manchester, Bleacher,
Dyer, and Finisher, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR BEETLING WOVEN FABRICS,"
to be as follows:—
My Invention consists in winding the fabric to be beetled on a flat
blade of iron, which blade in revolving winds the fabric upon it, when
the lap is finished the blade is taken out, and the laps so formed or
otherwise are placed on the bed of the beetling machine, on which they
aro traversed laterally to and fro by means of broad belts, the ends of

page_text: which are wound on two rollers. The stampers which act on the laps
of the fabric are raised by cams and fall by their own gravity in the
usual manner, the lower face of the stamper is concave and serrated.
Tho to-and-fro motion of the broad belts is produced by a crank pin
projecting from a pinion driven by a wheel on the cam shaft, and this 5
crank pin works a lever, to which is jointed a double catch acting on a
friction pulley, to this pulley is fixed a toothed wheel which gives
motion to a chain passing around toothed wheels on the axles of the
rollers on which the ends of the broad belts are wound.
In order to reverse the motion of the broad belts and to vary tlıcir 1
traverse I attach two adjustable blocks to the chain, which blocks act
alternately on a lever fixed to the axle of the double friction catch above
referred to, thereby causing the friction pulley to move alternately in
contrary directions. The mechanism for traversing the belts to and fro
may be varied.
By means of these improvements the fabrics are brought out to their

SMITH, of Chcetham, in the City of Manchester, Bleacher, Dyer, and
Finisher, send greeting.

grant unto me, the said John Smith, Her special licence that I, the
said John Smith, my executors, administrators, and assigns, or such
others as I, the said John Smith, my executors, administrators, and
assigns, should at any time agree with, and no others, from time to

United Kingdom of Great Britain and Ireland, the Channel Islands, and
Isle of Man, an Invention for "IMPROVEMENTS IN MACHINERY OR Apparatuș
FOR BETTLING WOVEN FABRICS," upon the condition (amongst others) that I,
the said John Smith, my executors or administrators, by an instrument
in writing under my, or their, or one of their hands and seals, should
particularly describe and ascertain the nature of the said Invention, and
in what manner the same was to be performed, and cause the same to be
filed in the Great Seal Patent Office within six calendar months next
and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said John Smith, do hereby declare, the
nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement (that is to say) :-
.
My Invention consists in winding the fabric to be beetled on a flat
blade of iron, which blade in revolving winds the fabric upon it, when
the lap is finished the blade is taken out and the laps so formed or
otherwise are placed on the bed of the beetling machine on which they
are traversed laterally to and fro by means of broad belts, the ends of
which are wound on two rollers. The stampers which act on the laps
of fabric are raised by cams and fall by their own gravity in the usual
manner, the lower face of the stamper is concave and serrated. The
to-and-fro motion of the broad belts is produced by a crank pin projecting
from a pinion driven by a wheel on the cam shaft, and this crank pin
works a lever, to which is jointed a double catch acting on a friction
pulley, to this pulley is fixed a toothed wheel which gives motion to a
chain passing around toothed wheels on the axles of the rollers, on which
the ends of the broad belts are wound.
In order to reverse the motion of the broad belts and to vary their
traverse I attach two adjustable blocks to the chain, which blocks act
alternately on a lever fixed to the axle of the double friction catch above
referred to, thereby causing the friction pulley to move alternately in.
contrary directions. The mechanism for traversing the belts to and fro
may be varied.
By means of these improvements the fabrics are brought out to their
...

page_text: And in order that my Invention may be fully understood and readily
carried into operation, I will proceed to describe the accompanying
Sheet of Drawings, reference being had to the figures and letters marked
thereon.
Fig. 1 is an end view, and Fig. 2 a side view of a machine for beetling
woven fabrics to which my improvements are applied; Fig. 3 is a
detached view on an enlarged scale of part of my improvements.
a, a, are the standards; b, the driving shaft; c, the cam shaft; d, d,
the stampers; e, the broad belts which traverse the laps of fabric to and
fro under the stampers, and which are wound on the rollers f,f. These:
parts are made as usual. The lower face of the stampers instead of
being plain as now customary I make concave, as shewn in Fig. 2 and
serrated as shewn in Fig. 1, by which improved shape the action of the
stampers produces more effect on the fabric than heretofore.
The
to and fro motions are imparted to the broad belts e by the following
improved arrangement or combination of machinery; to the end of the
driving shaft b is fixed a slotted disc b', in which is the adjustable crank
pin, to this crank pin is suspended the link 9 the lower end of which
is connected to the horizontal arms of the double elbow lever h, which
oscillates on the stud i, this lever is shewn best in Fig. 3, and it is
provided with bosses at the elbow to support the short shaft j, at the
outer end of this shaft is fixed the crank j¹, and between the arms of
the double elbow lever is the double catch j³ which is also fixed on the
shaft j, this double catch takes into the V groove of the friction pulley k
which is loose on the stud i and to which the toothed wheel is fixed.
To the axles of the rollers f,f, are fixed the toothed wheels ƒ',ƒ³, and
these wheels are driven from the wheel k¹ by means of the chain 7, to
which the two adjustable blocks m and n are attached. To the double
elbow lever his jointed the lever o the upper end of which is slotted,
and in this slot the crank j¹ enters, the lever o is held in position by the
spring o' which is also fixed to the lever h. When the machine is at
work and the left hand side of the double catch ƒ is in gear with the
friction pulley & the block m is gradually approaching the double elbow
lever h, and as soon as the point of the block m presses against the
lever o it reverses the position of the double catch ³, and brings the
right hand side of the catch into gear with the friction pulley, by this
means as the machine continues its work the direction of motion of the
chain / is reversed, and then the block » gradually approaches the double

page_text: elbow lever / until the point of the block comes against the lever o,
which is then in the position shewn in dotted lines in Fig. 3, and again'
reverses the position of the double catch . By this arrangement a
self-acting to-and-fro motion is given to the belts e and to the laps
of fabric resting upon them, and the length of the traverse can be
varied by setting the blocks m and n nearer to or further from each
other.
Having thus stated the nature of my Invention and described the
manner of performing the same, I declare that I claim,-
First, making the lower face of the stampers of beetles concave and
serrated as shewn.
And, secondly, the self-acting machinery for reversing the direction
of motion of the laps of fabric to be beetled, as shewn and described, or
any modification of the same.
In witness whereof, I, the said John Smith, have hereto set my hand
,and seal, this Twenty-sixth day of October One thousand eight
hundred and seventy-two.
