Improvements in Hand Cleaning Cards.
I, ALBERT KERN, of the Firm of Kern & Schervier, Manufacturers, of Aix-la-
Chapelle, 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 present invention has for its main object to provide important improve-
ments in the clearing of card clothing by doing away with the great drawbacks
which are experienced in the ordinary method (that is still employed almost
universally) of mounting and fixing the foundation plates of cleaning cards.
These drawbacks result mainly from the fact that the fixing of the foundation
plates of card clothing on the ordinary tablet by means of nails or pegs presents
prominent disadvantageous features in those cases where it is desirable to have a
smooth surface, whilst the mounting and the nailing necessitate considerable
time, and the work is difficult. Furthermore, in following the ordinary method
of nailing it is scarcely possible to obtain a uniform tension of the card, and
with this old method it is utterly impossible to obtain a tension of the card that
is capable of being regulated, and to replace it instantly by another tension
according to the requirements of cards of all counts or numbers. Improvements
made in this field, deserve therefore a special consideration, the more so, because
the mode of cleaning is of vital importance in relation to the tear and wear of
cards in all spinning mills.
The above mentioned drawbacks are entirely obviated by the present invention.
The accompanying drawings illustrate by way of example, a form of construc-.
tion of this invention and in these drawings:
Figure 1 is a view in plan, and
Figure 2 is a cross section of a mounting of a cleaning card, constructed in
accordance with the principles of this invention.
The nailing of the foundation plates is entirely dispensed with. The plates b
are provided on their longitudinal edges with metal strips a which are bent
back at an acute angle and which maintain a very efficient closure such that
nothing can adhere thereto. The plates are adapted to be slipped with the
greatest ease and rapidity upon the tablet c. Similarly the plates b can be
removed and replaced with ease and rapidity (according to the requirements
of the various gauges or numbers of the iron or steel wire. By all these arrange-
ments there is realised, not only a great saving in time, but also a considerable
reduction in the number of mounts and of cards that were necessary formerly.
For the purpose of obtaining a firm support for the sliding movement of the
plates of the cards, there has been provided at the lower end of the tablet upon
which the said plates rest, a stretching device d which is capable of being moved
at right angles to the direction of its length and to which is hooked the lower
frame of the plate of the card. The stretching device as well as the screw nut
block e, are fitted in notches or cavities formed in the tablet.c as also in the
bandle ffixed to the tablet. The arrangement and construction of the stretching
device and of the block is such that these latter do not project beyond the

page_text: surface of the tablet c.
The above mentioned block e serves as a guide for a
screw which, at the point where the handle is connected to the tablet, passes
vertically through an extension that projects from the handle and ends in a ring h
or other device which will enable it to be turned easily. By tightening up the
screw g, the displacement of the stretching device which can be effected within
the most narow limits, will produce with great ease the tension of the plate of
the card, and will enable a supplementary tension to be imparted at any desired
moment to the said plate, which operation has been utterly impossible heretofore
and which constitutes an important and useful improvement..
The form of the handle as also the form of the tablet may be modified according
to desire.
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:-
A new method of mounting the plates of hand cleaning cards characterized by
the fact that these plates are provided with binding strips and are slipped upon
their tablet and are fixed firmly thereon without nailing or the like by means
of a stretching device, and by the fact that these plates can be easily, rapidly,
and uniformly stretched and their tension adjusted at will by means of a screw
arranged at the centre of the tablet, substantially as hereinbefore described.
