PROVISIONAL SPECIFICATION.
Improvements in and relating to Looms for Weaving Royal Axminster
or Moquette Tufted Fabrics.
We, JAMES HUMPHRIES & SONS LIMITED, of Kidderminster, in the County of
Worcester, Carpet Manufacturers, and JAMES PERCIVAL HUMPHRIES, of the same
place, a Director of the said Company, Carpet Manufacturer, do hereby declare
the nature of this invention to be as follows:-
This invention relates to the employment of improved mechanism for raising
the loops or tufts from the back of the carpet to the front, and keeping them
in their place when lifted.
Heretofore a plain single comb has been used, or a pair of combs, one of the
pair following the other and working independently, or a plain bar or plate,
working in advance of the comb.
The object of our invention to be described, is an arrangement or construction of
mechanism the object of which is to prevent as far as possible, any of the tufts
of yarn failing to be brought to the surface from the back, which faulty opera-
tion is likely to occur with the ordinary plain single comb.
For this purpose we employ a comb of a certain thickness with a grooved
centre, the front part of the comb slightly higher than the back portion of the
comb. This comb is fixed to a bracket, which bracket gives the comb its motion
by the aid of cams or tappets operated by the loom axis and is attached to said
bracket by screws in slots, springs being arranged underneath the bracket acting
on the comb in such a way, that the comb is kept fast against the back of the
work as it comes forward to push the tufts up to the front of the carpet. The
front or higher portion of the comb by this means as it comes forward places the
lower ends of the tufts in their proper position previously to their being forced
up to the front of the carpet by the comb passing through the ground ends, and
the back portion of the comb acting close to the work brings the tufts up to
their proper position.

page_text: place, a Director of the said Company; Carpet 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:--
This invention relates to the employment of improved mechanism for raising
the loops or tufts from the back of the carpet to the front and keeping them
in their place when lifted.
Heretofore a plain single comb has been used, or a pair of combs, one of the
pair following the other and working independently, or a plain bar or plate,
working in advance of the comb.
The object of our invention to be described, is an arrangement or construction
of mechanism the object of which is to prevent as far as possible, any of the
tufts of yarn failing to be brought to the surface from the back, which faulty
operation is likely to occur with the ordinary plain single comb.
For this purpose we employ a comb of a certain thickness with a grooved
centre, the front part of the comb slightly higher than the back portion of the
comb.
This comb is fixed to a bracket, which bracket gives the comb its motion by the
aid of cams or tappets operated by the loom axis and is attached to said bracket
by screws in slots, springs being arranged underneath the bracket acting on the
comb in such a way, that the comb is kept fast against the back of the work as it
comes forward to push the tufts up to the front of the carpet.
The front or higher portion of the comb by this means as it comes forward
places the lower ends of the tufts in their proper position previous to their being
forced up to the front of the carpet by the comb passing through the ground
ends, and the back portion of the comb acting close to the work brings the tufts
up to their proper position.
Such a double tooth comb is shown in the accompanying drawing wherein :-
Fig. 1 represents by sectional side elevation parts of a loom of the description
mentioned, the comb in the position it occupies before it begins to operate on a
tuft.
Fig. 2 shows the toothed comb in the act of bending up and bringing the
yarn from the back to the front position.
Fig. 3 shows the comb in its position after having finished its work and placed
the tufts of which only the end of each row is illustrated in their desired U or
iooped position.
Figs. 4 and 5 show by partial front view and edge view respectively the double
toothed comb separately.
The comb A has a grooved centre, dividing the respective two front and back-
longer and shorter-rows of teeth A¹ and A2, and this bar of combs is fastened to
a bracket B by screws C working in slots C', so arranged, that the springs D
pressing against the said comb, cause the front row of teeth A' to be always well
against the back of the cloth, and thus prevent the possibility of any small parts
of the tufts from getting past the front to the back of the comb.
In looking at Figure 1 the tufts E are represented at the back of the cloth,
preparatory to being pushed forward to the front.
The cams usual to this class of machine operating on the bracket B in the
ordinary manner bring the comb A forward, and push the ends of the tufts of
yarn, through the ground ends to the front, as shown in Figure 2.
Each of the teeth of the front division or part A¹ of the comb, are slightly
rounded on the top in the direction lengthwise of the bar of combs (see Fig. 4),
and thus assist in clearing themselves between the ground ends for the comb to
come through to the front, and keep the way clear for the back part of the
comb A to finally bring up the tufts, as shown in Fig. 3, to their proper place.
It will be noticed in referring to Fig. 4 that the lower row of teeth A³ are
square at the top, and thus help more effectually to bring up the tufts cleanly
to the front of the carpet or fabric.

page_text: The comb A as shown in Fig. 3, having placed the ends of tufts in their proper
position, instantly retires below the level of the surface of the cloth, in order to
be out of the way of the cutters (which are used in this class of loom) to sever
the tufts from the tubes, after being bound in the work as is well understood by
those ordinarily skilled in this class of manufacture.
This invention is adapted for use in the class of loom described in the Specifica-
tion of Letters Patent granted to S. Pitt (Smith & Skinner) dated January 18th
1877 No. 235.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:
-
1. The construction and use of combs with double rows of teeth of different.
heights of rows, and parts cooperating therewith for raising the ends or parts of
loops or tufts in the manufacture of Royal Axminster, or Moquette tufted fabrics,
substantially as and for the purpose set forth.
2. The double toothed comb device for manipulating the tufts of fibres to form
them into loops or tufts in the weaving of a Royal Axminster or Moquette tufted
fabric as set forth.
