Improvements in Stripping Comb Apparatus for Stripping the
Revolving Flats of Carding Engines.
We, THOMAS RODGERSON MARSDEN, Manager with Messieum Platt Bros. &
Co. Ld., of Oldham, in the County of Lancaster, Machinists, HENRY WALSHI,
Foreman with the said Company, and PLATT BROS. & Co. LD., aforesaid, do
hereby declare the nature of this invention to be as follows:-
Our said invention relates to improvements in stripping comb apparatus for
stripping the revolving flats of carding engines.
In carrying our invention into effect and as applied in conjunction with the
ordinary stripping comb apparatus, we retain several of the old parts, but instead
of the comb bar which carries the stripping comb being fixed as before to the
side arms which support it, we mount or pivot the said comb bar loosely in
bearings secured to the supporting arms so that it can turn easily on its axis.
We also fix on one end of the comb bar an arm or crank and connect the said
arm or crank by a connecting rod or tie to a pivot on the block shaft bracket or
other suitable fixed part of tho frame. The result of this arrangement will be
readily understood. The usual cam acting on one of the side supporting arms
causes them to rise and fall in the ordinary manner but owing to the addition
of the aforesaid crank and pivoted connecting rod which acts on the pivoted comb
bar, the comb bar in addition to its up and down movement receives a rocking
motion, on its own axis. The path, or arc in which the serrated edge of the comb
travels during its up and down motion, instead of having as heretofore its curve
or convexity in the same direction as the arc through which the flats travel
during the operations of stripping, has its curve or convexity in the opposite
direction to that of the arc through which the flats travel as they are taken round
by the star wheel carriers.
By these means we are enabled to strip the flats more effectually than has been
hitherto practicable. An advantageous feature of our invention when applied to
the ordinary stripping motion is that no additional cams are employed to produce
the described dual motion, consequently our improvements are easily applicable
to existing carding engines and at very slight expense.

5 Improvements in Stripping Comb Apparatus for Stripping the
Revolving Flats of Carding Engines.
We, THOMAS RODGERSON MARSDEN, Manager with Messieurs Platt Bros. &
Co. Ld., of Oldham, in the County of Lancaster, Machinists, HENRY WALSH,

page_text: Foreman with the said Company, and PLATT BROS. & Co. LD., aforesaid, 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 and necompanying drawings:-
Our said invention relates to improvements in stripping comb apparatus for
stripping the revolving flats of carding engines.
In carrying our invention into effect and as applied in conjunction with the
ordinary stripping comh apparatus, we retain several of the old parts, but instead
of the comb bar which carries the stripping comb being fixed as before to the
side arms which support it, we mount or pivot the said comb bar loosely in
bearings secured to the supporting arms so that it can turn easily on its axis."
We also fix on one end of the comb bar an arm or crauk and connect the said
arm or crank by a connecting rod or tie to a pivot on the block shaft bracket or
other suitable fixed part of the frame. The result of this arrangement will be
readily understood. The usual cam acting on one of the side supporting arms
causes them to rise and fall in the ordinary manner but owing to the addition
of the aforesaid crank and pivoted connecting rod which act on the pivoted comb
har, the comb har in addition to its up and down movement receives a rocking
motion, on its own axis. The path, or arc in which the serrated edge of the comb
travels during its up and down motion, instead of having as heretofore its curve
or convexity in the same direction as the arc through which the flats travel
during the operations of stripping, has its curve or convexity in the opposite
direction to that of the are through which the flats travel as they are taken round
by the star wheel carriers.
And in order that our said invention may be more fully understood we will
now describe the same with reference to the accompanying sheet of drawings.
Fig. 1 is a sectional view of our improved stripping comb apparatus together
with auch part only of a carding engine as is necessary to illustrate the
invention.
Fig. 2 is a view looking in the direction of the arrow Fig. 1, and showing the 3
bracket to which the connecting link is pivoted.
Fig. 3 is a front view or a view at right angles to Fig. 1.
Figs. 4 and 5 are detail views.
Upon the shaft a is keyed a cam 6 upon which rests a bowl c carried at the foot
of an arm d secured to the supporting or radial arm e vibrating upon a fixed a
contre el. It will be understood that these parts are old but instead of the comb
bar which carries the stripping comb being fixed to the side or radial arms e as
heretofore, we mount or pivot the comb har loosely in bearings secured to the
radial arms e. Upon the ends of the radial arms we mount carrier blocks f
adjustably secured in position upon the ends of the arms e by means of nuts fi. 4
The carrier blooks f provide bearings within which the comb bar g can oscillato
freely.
The comb har g is provided with a crank A koyed thereon and a connecting
link is loosely mounted at one end to the crank hand at the other end to a
bracket or other suitable fixed part of the frame. Fig. 4 shows a view of the 4
connecting link i at right angles to Fig. 1 whilst Fig. 5 is a plan view of the
crank h. The result of this arrangement will be readily understood.
The cam acting on one of the radial arms e causes them to rise and fall in the
ordinary manner but owing to the action of the aforesaid crank A and pivoted
connecting rod or link which act on the pivoted comb bar g, the comb bar in 5
addition to its up and down movement receives a rocking motion on its own
axis.
The path or are in which the serrated edge of the comb g' travels during its
up and down motion is therefore diverted and instead of having as heretofore
its curve or convexity in the same direction as the arc through which the flats 5
travel, has its curve or convexity in the opposite direction, as shown in dotted

page_text: lines in the drawing. By these means we are enabled to strip the flats more
effectually than has hitherto been practicable.
An advantageous feature of our invention when applied to the ordinary strip-
ping motion is that no additional cams are employed to produce the described
dual motion, consequently our improvements are easily applicable to existing
carding engines and at very slight expense.
Having now particularly described and ascertained the nature of our said in-
vention and in what manner the same is to be performed we declare that what we
claim is.-
The general arrangement, construction and combination of parts comprising
the improved stripping comb apparatus for stripping the revolving flats of carding
engines substantially as described and illustrated.
