JONATHAN HOLDEN and JOHN EDWARD HOLDEN, both of Reims, France
PROVEMENTS IN MACHINES FOR CARDING WOOL AND OTHER EIBROUS MATERIAL."
These improvements have reference specially to double carding machines, their
object is to augment considerably the effective produce or yield of these machines by
means of a simple and inexpensive modification.
In order that these improvements be clearly understood we have represented at
Figure 1 of the annexed Sheet of Drawing a portion of ordinary double card, and
at Figure 2 the same portion modified in accordance with our new system.
This portion of the carding engine is compressed between the two large drums
T, T, in which the combing cylinder P is placed. In the ordinary system of
machine, Figure 1, the wool is taken from the drum T by the combing cylinder P
at their point of contact O, it is afterwards taken from the combing cylinder by
the stripper N at the point of contact A and immediately transferred therefrom to
the drum T¹.
In this arrangement the combing cylinder merely acts the part of an inter-
mediate agent between the two drums in order to transfer the fibrous material from
the one to the other.
We have been enabled by a simple arrangement easily put into practical arrange-
ment, and without otherwise materially altering the machine itself, to double the
action of the combing cylinder by causing it to effect at another part of its travel
an additional action of considerable value.
--
This arrangement, which is represented at Figure 2, consists in bringing the
cylinder T in circumferential contact with the combing cylinder P and in placing a
second stripper N¹ underneath this point of contact C. Under these circumstances
the following action takes place, the textile material taken from the drum T by the
combing cylinder P at the point O is transferred by the stupper N₁ at the point B
to the drum T and at the same tine operated upon or carded, for it acts at this
Price 4d1

page_text: point as a working cylinder and not as a comber,,then the stripper N which main-
tains its original position in the carding engine transfers from the combing
cylinder P at the point A to the drum T the fibrous material which the combing
cylinder had previously received at the point of contact C from the drum T².
This novel action of the combing cylinder necessitates its being supported in
peculiarly constructed bearings in order to regulate accurately its contact with both
cylinders. For this purpose a bearing is required which can be moved both in a
horizontal and a vertical direction.
We have represented at Figure 2 tho bearing which we have imagined for this
purpose, it consists in a block with vertical sides in which we place a flat sided
bearing free to slide up or down within the same, this bearing is bored out to
receive the shaft of the combing cylinder which rotates within it, a screw placed
under the bearing and which traverses the frame, and the bearing in which it is
tapped serves to raise the bearing at any required height, whilst a screw placed
over the bearing serves to fix it at such required height, the horizontal displace-
ment is obtained as usual by means of a screw attached laterally to one side of
the block, and which traversing an upright lug on the framing is worked to the
right or to the left by means of nuts placed on either side of the lug, a vertical bolt
passing through the framing and a slotted flange of the bearing on its opposite side
serves to maintain the block in the horizontal position required Similar bearings
are adapted for the same purpose to the stripper N¹.
As it will be seen this modification is easily made and can be obtained in many
different manners, for instance, by bringing the two carding- drums T and T closer
together, or by simply augmenting the diameter of the combing cylinder, the result
of this improvement is a better utilisation of the working parts of the card,
thereby producing a more perfect working of the fibrous material, for whilst the
cylinder P still works as a comber at the point O it is transformed into a regular
worker at C, and its efficiency in this case is considerably augmented in so much
as its diameter is much greater than that of the other workers, and thereby forms
a much larger or more extensive working surface with the drum T
Having thus explained the nature of our improvements; as well as the means
for putting the same into practical operation, we claim as our Invention--
Firstly The arrangement .above described of bringing the combing cylinder in
simultaneous working contact with the two great drums of a carding-engine.
Secondly. The addition to the above arrangement of parts of a second stripper
placed below in simultaneous working contact with the combing cylinder and the
after drum.
And, Thirdly. Conjointly with the above arrangement of parts of the blocks and.
bearings for adjusting vertically and horizontally the combing cylinder and the
under stripper.
In witness whereof, we, the said Jonathan Holden and John Edward Holden,
have hereunto set our hands and seals, this Twenty-third day of August,
in the year of our Lord One thousand eight hundred and seventy-six.
