CORDELE DE ECIFICATION.
I, ROBERT SCHAELLIBAUM, of 6 Robert St Upper Brook Street Manchester in
the County of Lancaster, Engineer, do hereby declare the nature of my invention
for "IMPROVEMENTS IN OPENERS AND SCUTCHERS ALSO APPLICABLE TO SOME
OTHER SIMILAR MACHINES USED IN THE PREPARATION OF COTTON OR OTHER
FIBRES"
and in what manner, the same is to be performed to be particularly
described and ascertained in and by the following statement:-
My invention relates to improvements in openers and scutchers which improve-
ments are also applicable to some other similar machines used in the preparation of
cotton or other fibres, such as Willows, or carding engines with the exception
of what are known as Crighton openers, and has for its object to make such
machines more efficient in opening the cotton or other fibres and extracting,
impurities therefrom, than heretofore has been the case.
And in order that my invention may be better understood I have caused to be
appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures.
Fig 1 on annexed drawing shows my improvements as applied to an opener
system, Taylor and Lang.
Fig 2. as applied to scutchers & Fig 3. as applied to the licker-in of a carding
engine.
In carrying out my invention and when applying the same to all kinds of
Willows & openers (except Crighton openers) it consists of a stationary comb A
see Fig 1. constructed of a plate a of wrought iron or brass or other suitable metal
and provided with steel pins b. The section of the plate or foundation is generally
a parallelogram, the top edge thus forming a knife and acting like the top edges of
the usual grid bars e employed in these machines. The pins b which may be of a
round or a flat section are set at such a distance from each other that the largest
impurities which generally happen to pass on with the cotton in the respective
machines are permitted to pass between the pins b, thus preventing anything from
sticking between the pins which would necessitate stripping or cleaning.

page_text: The pins bare set at an angle to their plate or foundation with the points
inclined against the direction in which the cotton is moving, thus affording the
most grip.
The plate or foundation a, itself is also arranged inclined against the beater or
cylinder f, and the last row of pins which the cotton reaches being nearer to the
beater or cylinder f than the first row, or instead of arranging the plate or
foundation a inclined, the pins of several rows may gradually grow longer in the
direction in which the cotton moves for insuring an equal strain on all the rows as
illustrated.
When applying my invention to a scutcher and also to a certain kind of openers,
see Fig 2. I combine the stationary comb A with a grid B which latter consists of
a suitable number of wrought iron or steel bars g of the section as illustrated.
These iron or steel bars are carried by and arranged to slide in a groove in the
bracket h, the stationary comb A being suitably fastened to the bracket h.
The inclination of the bars g to the radius of the beater i or cylinder increases
from the top to the bottom "and also the distance of the bars g from each other in
the same direction, for the purpose of obtaining a uniform draft of air through the
grid B from the top to the bottom. In certain cases, however, the succession of
the bars g may be reversed.
This combination is intended for scutchers and openers with small porcupines,
and for the feeding arrangement of Crighton Openers.
When applying my invention, in a carding-engine to the licker-in C see Fig 3,
I provide or form the comb A with finer and more pins 6 than in the applications
already described, and arrange the comb A underneath the licker-in between the
ordinary knife k and shell
Having now described and ascertained the nature of my said invention and in
what manner the same is to be performed I declare that what I claim, is
(1) The exclusive use and application of stationary combs to the grids of openers
or similar machines used in the preparation of cotton or other fibres substantially
as described and illustrated in the annexed drawing.
(2) The exclusive use and application of one or more stationary combs to the
top covers of Willows or openers with large porcupines and to openers in which
the common porcupines are replaced by an axle bearing a quantity of steel blades
or other arrangement for carrying the cotton or other fibres forward.
(3) The exclusive use and application of stationary combs as described, to
scutchers,, with or without special grids, as well as to machines being a combination
of openers and scutchers.
(4) The exclusive use and application of stationary combs as described, to the
licker-in of carding engines, for cotton or other fibres.
Dated this 4th day of June A.D. 1885.
