page_text: I SAMUEL BEAUMONT of Roubaix, France, Card Manufacturer 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:—
The primary objects of my invention are to provide simple and efficient means
for adjusting the distance and position of the strippers used in carding engines
between themselves and the card cylinder and for facilitating the removal when
required of the stripper from the card cylinder while at the same time the stripper
adapts itself in relation to the card cylinder so that no injury to the cards them-
selves can under ordinary circumstances occur as heretofore and this is more
particularly the case during the action of withdrawing or replacing the stripper
into its normal position with reference to the card cylinder previous to the removal
of the fluff or dirt and other extraneous matter accumulating thereon.
According to my invention I fit or mount the stripper card on a frame, which
adjusts its position when necessary, while at the same time the stripper and its
frame can be brought back clear of the card cylinder when it is required to remove
the stripper from same, all as hereafter described.
The frame by which the stripper is carried is arranged so that it has imparted
to it or is capable of receiving when required a to and fro motion and this may be
accomplished by any suitable mechanical contrivances. A convenient arrangement
is to mount or to carry the stripper segment or frame on spindles either of round,
square or other convenient section sliding in apertures or grooves in a framework;
round the spindles there are helical or other springs to allow the spindles carrying
the stripper a to and fro, or it might be a resilient motion in which latter case
when the stripper is brought down to the cylinder the springs allow the stripper to
yield when necessary and when it is required to remove the stripper from the
cylinder and during its return motion the spindles and stripper are withdrawn and
the stripper can be thrown back without dragging the cards of the stripper through
those of the carding cylinder.

page_text: In order that my invention may be fully and clearly understood I will proceed
to describe the same with reference to the accompanying drawings.
Figure 1 is an end elevation partly in section of a card stripper and frame
connected therewith constructed according to my invention, Figure 2 is a
sectional plan of the same showing the framework broken for the economy of
space; Figure 3 is a vertical section, drawn on a somewhat smaller scale than
Figures 1 and 2 showing the stripper applied to the cylinder of a carding engine;
Figure 4 is a similar view also drawn on a smaller scale, of the stripper showing
the same in the act of being removed from the card cylinder.
The above views show the stripper in the case where springs act to close the
stripper frame up to the card cylinder or in other words to change or to adjust the
position of the stripper in relation to the card cylinder; and Figure 5 is a view in
sectional plan of a portion of the stripper and its frame where a reverse action of
the mechanism is shown the stripper being brought back by the spring action and
brought up to the card cylinder by a cam or eccentric.
Similar letters of reference refer to like parts in all the Figures.
A is the segment or wood frame to which stripper cards are connected. H shows
a portion of the card cylinder; B B B'are the spindles on the underside or back of
the frame A which carry and support the said frame; C C C are bracket frames
bolted or otherwise connected to a cross shaft D, the ends D₁ of which are carried,
or work in bearings in the brackets marked K shown at Figures 3 and 4 where
for example the emery roller is usually carried in revolving flat carding engines, in
.other carding engines suitable brackets for this purpose may be attached either to
the bend (half moon) or to frame of engine. The spindles B pass through slots in
the bracket frames C and there are collars E secured to these spindles by screws
in such position that the said collars act as stops to the spindles and regulate the
extent of the to or fro movement of the said spindles; F F F are helical springs
round the spindles B between the collars E and the cross shaft D; G is a cam or
eccentric operated by lever G₁ for imparting a to or fro movement through one
or more of the spindles B to the segment A. The cam or eccentric may be
arranged or placed at any convenient position, for example there may be a cam at
each end of the shaft D or of an auxiliary shaft D₁ Figure 5 supported therefrom
by suitable bracket and operated by a lever G¹ at one end, or it may be supported
on an adjustable slide F¹ Figures 1, 2 and 3 which may be fixed by set screws in
position on the prolongation of one of the spindles B¹. This cam may be utilized
to draw the stripper frame A back from the carding cylinder H so that the stripper
may be removed therefrom in which case the springs F are compressed until the
action of the cam G on the cross shaft D is removed when the expansion of the
spring again brings the stripper into position for working into the dents of
the teeth on the carding cylinder and it is this arrangement of the stripper which
is shown at Figures 1, 2, 3 and 4 whereas at Figure 5 the stripper is pressed into
position to work in the card cylinder by the cam itself and the spring brings it
back. At Figures 3 and 4 I have shown the several positions of the stripper and
stripper frame; at Figure 3 when the stripper is engaged for work with the cards
of the card cylinder, and at Figure 4 the full lines show the stripper drawn back
with the teeth clear of the card cylinder teeth and the dotted lines show the
position of the stripper when it is swung back for clearing or cleaning.
The frame and shaft D and handle G¹ may be operated by hand the shaft D
being provided with another handle fixed to a prolongation of the spindle at D' or
it may be operated automatically by means, for example, of an auxiliary cross
shaft having cranks or eccentrics and being connected by rods to equivalents for
the handle G¹ and the handle not shown in the drawings, on the prolongation D¹
the auxiliary cross shaft being rotated by band or strap from any prime mover.
I do not limit myself absolutely to the arrangements described for fitting the
stripper frames and for imparting the to or fro motion thereto although I have
found the means described a convenient way of carrying the invention into effect.

page_text: 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 strippers for or in connection with carding engines the imparting to same of
a to or fro or adjustable reciprocating motion whereby the stripper can be removed
from the card cylinder and placed in position for recommencing the operation of
stripping without touching the teeth of card cylinder all substantially as and for
the purposes set forth.
