Improvements relating to the Fastening of Card Clothing to the
Flats of Revolving Flat Carding Engines, and to Devices for Use
therein.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, 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:-
This invention relates to the form of the clips, and especially to the manner or
method of providing them with prongs or spurs which are formed from the clip
itself, so to speak, rather than by extensions from its edge. This result is attained
by punching or otherwise forming in the edge of the plate from which the clip is
made, prongs or spurs, the greatest diameter of which is at an angle to the edge
of the plate and within the edge of the plate, the substance of such prongs being
obtained from or within the edge of the clip. This makes a very considerable
Baving in the cost of the clip and provides teeth of great strength and holding
power. The teeth being arranged at an angle in respect to the edge of the clip are
stronger, take better hold of the edge of the wired clothing and consequently act to
unite it more securely, firmly and rigidly to the clips and through them to
the flats.
Referring to the drawing:
Figure 1 is a perspective view of the clip and
Figure 2 is a sectional view showing the said clip attached to the clothing.
A represents the side clip. It is formed from a flat metal plate preferably thin
iron and steel and to the angular shape shown in Figure 1, the part or section a
lapping upon a surface of the card clothing near its edge, and the part a' extending
by the edge and the edge of the flat to lap upon the inner surface of the flat. The
prongs a are formed by cutting, punching, or severing sections upon lines extending
diagonally inward from the edge of the part a of the clip, and then bending,
folding or turning these cut sections upward or so that they extend from the inner
face of the part a and are parallel with each other and with the greatest diameter
upon an angle with the edge of the said part and within it. The length of the
prongs or points and their sharpness will depend upon the degree of the angle of
the cuts in relation to the said edge. This provides the clip with points or spurs
which are very strong and which are formed from the material of the part a.
It will be seen that the edges of the clips effect a novel combination with the
edges of the clothing in these particulars: First, the prongs make small cuts in the
clothing considering their width and strength and thus preserve the strength of
the clothing at the edge as much as possible consistent with the manner of engaging
it; second, that by their wedge-like edges they draw the clothing to some extent
as they are being inserted into its edges.
Clips of this character may be attached closely to the edges of the clothing
thereby providing space for a large wired section.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me
by my foreign correspondent, I declare that what I claim is :-
1. As an improved article of manufacture, a clip for attaching the edges of card
clothing to flats, the same comprising a long metal plate, having the section a,
which is adapted to lap or extend upon the surface of the card clothing near its
edge, and has formed from its substance by diagonal slits extending inward from
its edge, tlie short prongs a', which are within the outer edge of said section, and
bear an angle thereto, the said clip also having the section a bent at a right angle
to the section a, as and for the purposes described.
2. In à clip for fastening the edge of card clothing to flats, the narrow section a
for extending or lapping upon the outer surface of the clothing, adjacent to its
edge and having formed therein within the inner edge of said section a short
prongs a to engage the edge of the clothing only, and the points of which are
adapted to be upset upon the inner surface of the clothing, the said prongs being
at an angle to the inner edge of the said section; and the said section having means
for fastening it to the flat, which are adapted to extend above the edges of
the clothing and flat; and lap upon the upper surface thereof; as and for the
purposes described.
3. The combination of the flat, the clothing having the unwired edges and the
clips uniting the clothing to the flat by means of prongs formed within the outer
edge of the section a of each clip, bent at an angle to said edge, and making an
engagement with the edges of the clothing, as and for the purposes specified, and
the said clips having sections a¹ which extend about the outer edges of the clothing
and the flats, and lap upon the under surface of the flats.
4. The combination of a clip having teeth bent at an angle to the edge which
laps upon the clothing, and the outer edges of which teeth are inclined from their
points outwardly, with the edge of the card clothing with which said inclines are
engaged, and by which a slight straining action upon the clothing in the act
of inserting the prongs is produced.
5. A clip having a lapping edge or section a provided with prongs a provided for
engaging the edge of the clothing, set at an angle to said edge and separated from
each other by straight or uncut sections of said edge, as and for the purposes
described.
