Improvements in Gigging or Napping Machines.
I, LOUIS CLARENBACH Jr., of 204 S. 3rd Street Philadelphia, Pennsylvania,
United States of America, Dealer in Textile Machinery, 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 :-
My invention relates to improvements in that class of gigging or napping
machines in which the napping is accomplished by the contact of the cloth with
a series of carding or napping rolls which have a forward motion around a common
shaft as well as an independent motion on their own axes in the opposite direction,
and consists of novel devices for controlling the relation between the said motions
securing a uniform friction for all of the napping rollers employed, and adjusting
or regulating the speed of the carding or napping rolls as required.
In the accompanying drawing,
Figure 1 represents an end elevation, partly broken away, of a gigging machine
embodying my invention.
Figure 2 represents a similar view on an enlarged scale of a part of the machine,
showing my improvement applied thereto.
Figure 3 represents a partial side elevation, broken away, of my improved
mechanism.
Similar letters of reference indicate corresponding parts in the several figures.
A designates the frame of the machine, supporting ring frames B, having
slots C, and centrally located within said frames B is a driving shaft D, to the
ends of which are secured spider frames E having radial arms F. The ends of
said arms are forked, and receive the spring-pressed bearings G of the journals of
a series of carding or napping rolls H, arranged in the form of a circle around the
said shaft D.
To the journals of said rolls are keyed the friction pulleys J, which are revolved
by contact with the inner surface of an annulus 9. Guide rolls L, and feed rolls M
are supplied at different parts of the machine, as shown, over which the cloth to be
napped is slowly fed against the carding rolls H.
A hanger 1 is secured to one side of the frame A, wherein a gear wheel 2 is
removably or adjustably mounted. Said gear wheel 2 has a sprocket or analogous
chain wheel affixed thereto, traversed by an endless belt 4, which also runs over
a wheel 5 keyed to the end of the shaft D.
Standards 6 are located adjacent to the hanger 1, and gear wheel 2, as seen in
Figure 2, and support a gear wheel 7 having a smaller gear 8 attached thereto,
which meshes with the said gear 2. The teeth of the gear 7 mesh with the
peripheral teeth of the annulus 9, the latter being located within the ring frame B
and constructed with a web 10 or arms if desired, said web being mounted loosely
on the shaft D.
The motion of the shaft D is transmitted through the belt 4 to gear 2, and
through gear 7 projecting through the slot C of frames B to the annulus for revolving
the latter at a greater or less speed and in the same direction as said shaft D, as
fully shown by the arrows.
The friction pulleys J on the ends of the carding rolls H, bear against the
flange of the annulus,

page_text: The spider frames E revolve at a uniform rate of speed and carry the rolls H
forward. The annulus is given a varied motion according as the nature of the
cloth requires a vigorous or light treatment to produce the nap.
The carding rolls therefore moving in one direction around a common shaft D
at a uniform rate of speed, are of themselves revolved in a reverse direction by
contact with the annulus 9, which latter according to the arrangement of the
gearing is given a fast or slow movement.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
First. In a gigging machine, an exteriorly toothed annulus, friction rollers, in
contact with the interior of said annulus, and napping rolls connected with said
friction rollers with means for rotating said annulus and rolls said parts being
combined substantially as described.
Second. A gigging machine having an exteriorly toothed annulus, a frame
carrying a series of napping rolls, a driving shaft with which said frame is con-
nected, friction pulleys on the napping rollers bearing against said annulus, and
gearing for operating said annulus, the friction rollers being within said annulus,
and the latter loosely mounted on said driving shaft, the several parts being
combined substantially as described.
Third. A gigging machine having a frame carrying a series of napping rolls,
friction pulleys carried by said napping rolls, and an annulus whose exterior is
toothed and whose inner surface engages with said friction rollers, a gear wheel
meshing with said annulus and means for operating said gear wheel, said annulus
being loosely mounted on the driving shaft to which the frame of the napping rolls
is secured, said parts being combined substantially as described.
Fourth. In a gigging machine, a driving shaft and a frame thereon supporting
napping rolls, friction pulleys on said rolls, an exteriorly toothed annulus, said
pulleys engaging with the interior of said annulus, a gear wheel and means for
adjustably supporting the same, a gear wheel meshing with said removable gear
wheel and the toothed annulus, and means for operating the last named gear
wheel, said parts being combined substantially as described.
