Improvements in Stripping Comb Apparatus for Stripping the
Revolving Flats of Carding Engines.
I, SILAS WALMSLEY, of 44, St. Mary's Road, Bamber Bridge, Preston, in the
County of Lancaster, Head Carder, do hereby declare the nature of this invention
to be as follows:-

My said invention relates to improvements in stripping comb apparatus used
to effect the stripping of the revolving flats of carding engines as is well under-
stood.
Such stripping apparatus usually consists of a comb mounted on a bar caused
to vibrate through an arc parallel to that through which the flats travel. Owing
to the fact that combs so mounted are liable to drag through and injure the card
dents on their up-stroke it has lately been proposed to impart a secondary motion
to the comb bar in addition to the vibratory one so that the comb is caused to
move towards and from the dents. It is to this latter class of stripping comb
arrangement that my invention relates.
According to my invention I mount the comb bar loosely in blocks carried on
the outer ends of the side supporting arms so that the bar is free to move on its
axis.
The comb is preferably set so as not to actually touch the dents. To one end
of the comb bar I secure a suitably shaped bracket and in this bracket I form a
cam groove.
The contour of such cam groove is regulated by the particular
movement it is desired that the comb bar shall make on its axis as the bar is
vibrated up. and down. Within this cam groove or slot an anti-friction bowl runs
or plays this bowl being carried on a stud adjustably secured to a small bracket
bolted to the block shaft bracket. The anti-friction bowl might be carried from
an extension of the block shaft bracket or from any other suitable part.
The side supporting arms are vibrated in the ordinary manner by means of a
bowl running on a cam or excentric.
From the above it will be seen that in addition to its up and down movement
the bowl running in the cam groove compels the comb bar to turn or revolve on
its axis. This additional movement of the comb bar causes the stripping comb
to travel through a path or arc opposed to that through which the flats travel
so that the flats are effectually stripped by the comb on the down stroke without
its injuring the dents on the up stroke.
I prefer that the comb in commencing its down stroke, shall first move angu-
larly to the flats, then squarely to them, and finally move quickly away, this
final movement serving to effectually detach the stripped fibre from the comb.
The same path is of course traversed on the up stroke.
The method of imparting the additional movement to the comb bar as above
indicated is extremely simple and efficient and may be readily applied to existing
engines.

I, SILAS WALMSLEY, of 44,, St. Mary's Road, Bamber Bridge, Preston, in the
County of Lancaster, Head Carder, 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 accompanying drawings:-
:-
My said invention relates to improvements in stripping comb apparatus used
to effect the stripping of the revolving flats of carding engines as is well under-
stood.
Such stripping apparatus usually consists of a comb mounted on a bar caused
to vibrate through an are parallel to that through which the flats travel. Owing
to the fact that combs so mounted are liable to drag through and injure the card
dents on their up-stroke it has lately been proposed to impart a secondary motion
to the comb bar in addition to the vibratory one so that the comb is caused to
move towards and from the dents. It is to this latter class of stripping comb
arrangement that my invention relates.
My invention will be clearly understood from the following description when
read in conjunction with the annexed sheet of illustrative drawings.
In the said drawings.
Fig. 1 represents a side view of my invention applied to the vibrating comb
bar of an ordinary revolving flat card only so much of the carding engine being
shown as is necessary for a comprehension of my invention.
Fig. 2 is a plan of Fig. 1 looking in the direction of the arrow.
Figs. 3, 4, and 5 are detail views.
In carrying my invention into effect I mount the comb bar a loosely in blocks or
bearings a adjustably carried on the outer ends of the side supporting arms cc
so that the bar is free to move on its axis.
The comb a is preferably set so as not to actually touch the dents. To one
end a of the comb bar a, I secure a suitably shaped bracket band in this bracket
I form a cam groove 61. The contour of such cam groove is regulated by the par-
ticular movement it is desired that the comb bar shall make on its axis as the
bar is vibrated up and down. The bracket 6 is secured to the comb bar axis a
by means of a pinching screw 62 or in any other suitable manner. Within the
cam groove or slot b¹, an anti-friction bowl e runs or plays, this bowl being carried
on a stud or projecting carrier e¹ which is adjustably secured to a bracket f
bolted to the block shaft bracket y. The anti-friction bowl e might be carried
from an extension of the block shaft bracket or from any other suitable part.
The side supporting arms are vibrated in the ordinary manner by means of a
bowl bearing on a cam or excentric the bowl h being carried in an arm h¹
secured to the supporting arm cl.

From the foregoing description, it will be seen that in addition to its up and
down movement, the bowl a running in the cam groove or slot b¹, compels the 4
comb bara to turn or revolve on its axis. This additional movement of the
comb bar causes the stripping comb to travel through a path or are opposed to
that through which the flais travel so that the flats are effectually stripped by the
comb on the down-stroke and the stripped fibre detached from the comb as the
comb draws away from the flats on the termination of such stroke.
With the form of cam groove indicated in the drawings, the comb in com-
mencing its down-stroke will first move angularly to the flats, and then quickly
away, this final movement serving to effectually detach the stripped fibre from the
4

page_text: comb as above mentioned. The comb travels through the same path in the
reverse way on the up-stroke as will be clearly understood.
The method of imparting the additional movement to the comb bar as above
indicated is extremely simple and efficient and may be readily applied to existing
engines.
By varying the form of cam groove the movement imparted to the comb bar
is correspondingly varied.
.
I find, that owing to the more efficient action of a comb so mounted, it is not
necessary to strip the fluff brush nearly so often as when using the ordinary
vibrating comb.
Having now particularly 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:-
-
In stripping comb apparatus, the employment of a bracket attached to the
comb bar and formed with a cam groove or slot in which bears a bowl e so that
on the vibration of the comb bar a secondary movement is imparted thereto, in
the manner, and substantially as described and shown.
