PROVISIONAL SPECIFICATION.
Improvements in or connected with Apparatus for Weaving
Carpets.
I, IGNAZ GINZKEY, of Maffersdorf, Austria, Manufacturer, do hereby declare
the nature of this invention to be as follows:-
This invention relates to improvements in or connected with apparatus for
weaving carpets and has for object to impart a regular surface to the woven article,
for which purpose means are provided for evening and setting up (regulating) the
pile of the chenille thread introduced into the shed both before and after the same
has been beaten up by the lathe.
The accompanying drawings illustrate a carpet loom with my improvements
applied thereto, in which
Fig. 1 is a front elevation ;
Fig. 2 an end elevation;
Figs. 3, 4, 5 and 6 are various elevations of the apparatus for setting up and
brushing up the pile of the chenille thread introduced into the shed before being
beaten up by the lathe in different positions, and Figs. 7, 8, 9 and 10 are similar
views of the apparatus for combing up the pile of the finished article, that is to say,
after the chenille thread has been beaten up.
The apparatus for setting up and brushing up the chenille pile before being
beaten up by the lathe, comprises levers bb adapted to be oscillated by means of
the connecting rod.a and crank a', and carry a comb c that is provided with blunt
teeth and extends across the entire width of the loom. This comb c, which is
adapted to slide in guides on the levers bb, is capable of being moved horizontally
by means of the connecting rod d and lever d', and in thus moving is caused by
guide-rollers 62, which are situated in the guides b', engaging in a curved groove c³
formed in the combe, to make a parallel movement in a vertical direction.
After the chenille thread has been inserted into the shed and has been brought
into the position shewn in Fig. 3, the levers bbare rocked by means of the
crank a¹ towards the lathe e, until the comb c reaches the upper warp threads f,
which latter are at the same time pressed down to a slight extent by means of a
roller g, as shown in Fig. 4.
The comb c then begins its two-fold movement (to-and-fro, and up-and-down),
during which the pile threads between the warp threads are caused to pass to the
upper surface of the material.
Then the rotation of the roller produced by means of a chain / brings a brush g
fixed to this roller against the pile which is thus brushed up towards the material
(Fig. 5), after which the lathe.e is caused to beat up.
As the beating up of the lathe causes individual pile threads to become
disarranged in the finished fabric, there provided above the cloth beam w
(Fig. 7) another comb k which, when rocked about k', combs the pile and renders
it uniform.
The comb k is mounted so as to be capable of partial rotation on the end of the
curved arm which is rigidly connected to the shaft . This shaft is oscillated
by a crank disc m through the medium of the arm of the connecting rod.
In the position shown in Fig. 7, the comb k has reached its lowest position and
is taking into the chenille-pile as shown in the figure. If now the crank disc m be
rotated in the direction of the arrow a, the arms and will be oscillated in the
direction of the arrow B. In this manner the comb is caused to make a
movement around its centre of rotation towards the shed (in the direction of the
CD

page_text: arrow y) by a spring pressed pawl which is pivoted to the framing of the loom and
bears against the nose ' fixed to the comb (Figs. 7 and 8).
In this way the comb sets up again the pile threads that had become
disarranged.
By further rotation of the arms and 12 in the direction of the arrow B, the
nose slips over the point of the pawl n, as shown in Fig. 9, thus allowing a
spring to come into operation and pull the comb k back again into its initial
position..
Meanwhile the crank disc has changed its stroke and the parts and are again
rocked towards the cloth beam; the pawl n is again caused to engage behind the
nose, by the spring n', which has a constant tendency to press the pawl. against
the comb k.

I, IGNAZ GINZKEY, of Maffersdorf, Austria, 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 improvements in or connected with looms for weaving
carpets and has for object to impart a regular surface to the woven article for
which purpose means are provided for setting up or raising and combing or evening
the pile of the chenille thread introduced into the shed, both before and after the
same has been beaten up by the lathe or slay.
The drawings filed with my Provisional Specification illustrate a carpet loom
with my improvements applied thereto,
Fig. 1 being a front elevation; and
Fig. 2 an end elevation.
Figs. 3, 4, 5, & 6 are elevations of the apparatus used for setting up and brushing
up the pile of the chenille thread introduced into the shed before being beaten up
by the lathe or slay, the several views showing the parts of the apparatus in
different relative positions.
Figs. 7, 8, 9 & 10 are similar views to Figs. 3, 4, 5 & 6 respectively, showing the
apparatus for combing up or evening the pile of the finished article, that is to say,
after the chenille thread has been beaten up. The apparatus shown in Figs. 1 to 6
inclusive for setting up and brushing up the chenille pile before it is beaten up by
the lathe or slay, comprises levers which are arranged to be oscillated by a
connecting rod a and crank a', and carry a comb c that is provided with blunt
teeth c and extends across the entire width of the loom. The comb c, which is
adapted to slide in guides on the levers bb, is capable of being moved horizontally
by means of a connecting rod d and lever d', and in thus moving is caused, by
guide-rollers, which are situated in the guides & and engage in curved grooves c*
in the comb c, to make a parallel movement in a nearly vertical direction.
After the chenille thread has been inserted in the shed and has been brought
into the position shown in Fig. 3, the levers bare rocked, by means of the
crank a', towards the lathe or stay e until the comb e reaches the upper warp
threads, which are at the same time pressed down to a slight extent by means of
a roller g, as shown in Fig. 4.
The comb then begins its two-fold movement namely, towards the cloth beam
and upwards by means of which the pile filaments between the warp threads are
caused to pass to the upper surface of the material. The roller g is then rotated

page_text: in the direction of the arrow shown in Fig. 4, by means of a chain h, when the
comb c is in an elevated position, to bring a brush g', fixed to this roller, against
the pile, which is thus brushed up towards the cloth or carpet beam wo, after which
the lathe or slay e is caused to beat up the chenille thread. When the comb c is
in the position shown in Fig. 5, the brush g' is turned back into its initial position
in the direction of the arrow (Fig. 5) by means of a spring.
As the beating up of the lathe e causes individual pile filaments to become
disarranged in the finished fabric, there is provided above the cloth or carpet
beam w (Fig. 7) another comb k, which, when rocked about its centre of motion k',
combs the pile and renders its uniform. This comb is mounted, so as to be
capable of partial rotation, on the end of a curved arm which is rigidly connected
to a shaft . This shaft is oscillated by a crank disc m through the medium of
an arm and a connecting rod P. In the position shown in Fig. 7, the comb k has
reached its lowest position and is engaged with the chenille pile.
If, now, the crank disc m be rotated in the direction of the arrow a, the arms l
and will be oscillated in the direction of the arrow ẞ, and the comb k will bo
caused to make a movement around its centre of rotation ¹ in the direction of the
arrow a and towards the shed, by the action of a pawl n, which is pivoted to the
framing of the loom, and is caused to bear against a nose k² on the comb (Figs. 7
and 8) by a spring n'. In this way the comb k sets up again any pile filaments
that may have become disarranged.
a
By further rotation of the arms and in the direction of the arrow ẞ, the
nose slips over the point of the pawl n, as shown in Fig. 9, thus allowing
spring to come into operation and pull the comb k back again into its initial-
position. Meanwhile the crank disc m will have changed its stroke, the parts
and will be again rocked towards the cloth beam and the pawl n will be again
caused to engage behind the nose by the action of the spring n' which has a
constant tendency to press the pawl n against the comb k.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. In a chenille carpet loom apparatus for setting up and brushing up the chenille.
thread introduced into the shed, before it is beaten up by the lathe or slay,
comprising a horizontally and vertically movable comb c the movement of which
serves to bring the pile filaments between the warp threads to the upper surface of
the material, and a rotary brush g' adapted to brush up the pile filaments towards
the cloth or carpet beam, after the comb c has been raised therefrom.
2. In a chenille carpet loom, apparatus for combing and evening the pile on the
finished fabric, comprising a spring pressed rocking comb k, which, when moved
towards the shed, enters the pile, and, on its return movement, is rocked by means
of an arresting pawl n.
3. In a carpet loom, setting up and brushing up apparatus, constructed arranged
and operating substantially as herein before described with reference to and shown
in Figs. 1 to 6 inclusive of the drawings.
