page_text: LETTERS PATENT to John Tattersall, senior, and John Tattersall, junior, both
of Preston, in the County of Lancaster, Machinists, for an Invention of
"IMPROVED STRIPPING MOTION FOR CARDING ENGINES."
PROVISIONAL SPECIFICATION left by the said John Tattersall, senior, and
John Tattersall, junior, at the Office of the Commissioners of Patents on the
2nd April 1880.
JOHN TATTERSALL, senior, and JoHN TATTERSALL, junior, both of Preston, in
the County of Lancaster, Machinists. "IMPROVED STRIPPING MOTION FOR CARDING
ENGINES."
On the 29th of January last we lodged in the Patent Office an application and
Provisional Specification for a Patent for "Improved Stripping Motion for Carding
Engines," No. 393, which in due course was granted. In that Specification we
strip by a revolving brush or its equivalent, and altho we find it does its work
fairly well and is suitable in some cases, we find that an occilating clearer faced
with teeth of wire, bristles, or any other suitable material is much better in other
cases; we therefore add the above named clearer to our former Provisional Speci-
fication, which will now read thus:-
Our Invention consists of an "Improved Method of Stripping the Rollers of
Carding Engines," and is constructed in the following manner :-
Wo use the radial arms commonly used for stripping flat cards, to which
we apply a motion not dissimilar in outline to the one used by us in a
Patent granted to our Mr. John Tattersall, senior, on the 6th day of March 1877,
titled "Improved Stripping Motion for Carding Engines," and numbered 887.
That Invention was designed to strip flat, This roller Cards. The radial arins are,
as before, worked or radiated from or on the cylinder shaft, to which we fit a
moveable sectional traveling motion, made to travel from roller to roller in accordanco
with the number of rollers on the engine.
We fit and work between the two radial arms over and outside the circum-
ferential line of the rollers a circular or other shaped brush or its equivalent of any
suitable material, or an occilating clearer faced with teeth of wire, bristles, or any
other suitable material; these get their action either direct from crown wheel

page_text: or a camb in the crown wheel. Either the brush or clearer is now brought in
proper contact with strips or section of the circumference of each roller in rotation
on its radial journey going from one roller to another till all are visited and partialy
stripped, when the revolving brush or occillating clearer is thrown out of gear and
lifted clear of the rollers. It is radialy carried back again to the first roller, which
by this time has revolved just far enough for the end of the last stripping to come
again in contact with the brush or clearer or their equivalent, which is now again
in contact, and begins to strip as before, stripping a section of each.
The strippings are cleanly carried away by a comb, knife, clearer, or any other
convenient means, being periodicaly brought down in contact with brush, which, 1
having so cleared, retires, carry, and depositing such strippings in a receptacle
conveniently placed. (This applies to the brush only), but where the clearer is
-used-alone the brush_is_removed, and the clearer substituted, the strippings being
deposited as before stated. Such strippings are unbroken, and not-at-all-damaged.
Between each roller we fix a dead plate, having short teeth sufficiently long to 1
comb without holding the cotton, the Speeds and Actions of the several parts are
obtained by the usual mechanical appliences, not necessary here to describo.

"
JOHN TATTERSALL, senior, and JOHN TATTERSALL, junior, both of Preston, in
the County of Lancaster, Machinists. IMPROVED STRIPPING MOTION FOR CARDING
ENGINES."
Our Invention consists of certain improvements in stripping carding engines,
bearing relation to, but being a bettor description of, and carrying a few detailed
additions to Provisional Specification lodged by us on the 29th January 1880. In
our second Provisional Specification, lodged April 2nd 1880, we make the before
mentioned alterations and additions, which are herewith fully explained and
delineated, reference being made to the accompanying Drawings, the several Figures
being marked by corresponding letters of reference.
Fig. 1 is a side elevation of an ordinary carding engine, showing end of brush.
Fig. 2, front elevation of the same, showing brush in contact with roller,
stripping.
Fig. 3, camb in crown or sun wheel.
Fig. 4 is a similar side elevation to Fig. 1, but showing oscilating clearer in
contact with stripping board.
B
Fig. 5, front elevation of the same.
Fig. 6, side and front view of lever L.
A, in Figs. 1, 2, 4, and 5, is main shaft carrying the cylinder of carding engine;
radial arm; C, balanco weight; D, driving pulley giving motion to shaft E,
on which is wheel F, thence to double carrier wheels F and F2, F' giving motion
to wheel G on shaft G¹, on which is fixed brush H. On shaft G¹ is the carrier
wheel F, which gives motion to crown or sun wheel J, on the inside of which is
camb, Fig. 3, in the groove K of which works a bowl K, Fig. 6. M is the lower
or fulcrum end of lever L, working freely on a pivot secured in side frame B. On
the centre pivot a of crown or sun wheel J works a swing lever N, on the
outer end of which is worked planet wheel O geared into crown or sun wheel J.
On the inner side of this planet wheel is a rack pinion working in a groove round
rack quadrant P, from R to and round S, to and round R again, carrying the
stripping motion secured to radial arms B. This travels from carding rollers No. 1
to 15, when the planet wheel O, with its rack wheel inside having passed round
the quadrant to point S, turns from the upper to the lower side of rack, and by
means of turning the lower side of such rack lowers lever N, and raises dotted
bracket N¹ and connecting rod N2, thereby lifting brush wheel G out of gear and
brush H out of the way of all the rollers while it travels at one sweep from roller
15 to roller 1, just in time to meet No. 1 roller when rack wheel O turns round
from lower to upper side at point of quadrant rack R, thereby raising the swing
lever N, and lowering back dotted bracket N', and connecting rod N2, it brings
brush into gear again where it left of its stripping at its last visit, taking up the
strip where it before left off, going on rotatively stripping as before, when the
upper end of lever L is moved from c to d by the groove K in camb, Fig. 3, in
which works bowl K¹ in Fig. 6. Such movement draws downward the end of the
upper lever e at a to T, and the end of clearer U is brought down in contact with
brush H strips it, the lever L going back to c by the action of the camb lifts the
clearer U to the stripping board V, which cleans it. This occurs between each
stripping action on the rollers. The brush H continues to revolve during the whole
stripping action of the machine.
Over the wire board V in any convenient position we place a receptacle for
stripping.

page_text: Figs. 4 and 5 ara similar in radial arms. B; balance weight; C, driving pullies,
motions, and shafts, crown or sun and planet wheels, with double carrier wheels
driving wheel F, and working in a similar quadrantial rack, leaving out brush
H, wheel G, shaft G', dotted bracket N', connecting rod N2, and have corresponding
letters of reference, as in Figs. 1 and 2, but in this case the circular brush is
removed, the lever L is retained in all its integrity. The frame of the machine is
cut or made lower at X, Fig. 4, bringing board V much lower, the clearer board U
is shown now in action with its stripping board V, but when by the action of
lever Lat c being brought inward by the camb action to d, then the clearer U at
the end T would be brought down in contact with roller 8, Fig. 4, and strip &
section of rollers same as brush. It is then moved up by lever L brought in contact
with stripping board V, and thus the clearer is stripped. This clearer has a similar
action to the clearer in the before mentioned-Figs. 1 and 2; having the brush
removed it directly strips the rollers the same rotative manner as before named.
Having described our Invention and the way it is worked, we wish it to be
distinctly understood that we do not confine ourselves to the precise details wo
have had occasion to describe and refer to, as many variations may be made in
detail without deviating from the principle or main features, but what we claim as
secured to us herein is,―
First. The levers Land e with strippers W, dotted bracket N', and connecting
rod N2, and their method of connection and working, substantially as and for the
purposes herein before set forth.
Second. The stripping board V, the circular brush H, and method of driving,
fixing, and connecting same for sectionaly stripping rollers of carding engines
rotatively, substantialy as and for the purposes herein before set forth.
Third. The method of substituting the clearer for circular brush for stripping
direct the rollers sectionaly with the mode of applying the same, as shown on
Figs. 4 and 5, substantialy as and for the purposes herein before set forth.
Fourth and last. The general arrangements of the several parts, their uses, and
methods of application, substantially as and for the purposes hereinbefore set
forth.
In witness whereof, we, the said John Tattersall, senior, and John Tattersall,
junior, have hereunto set our hands and seals, this Twenty seventh day of
July, in the year of our Lord One thousand eight hundred and eighty.
