page_text: We ISIDORE WILLENS and EDOUARD DEPOORTER of Tourcoing in the Republic
of France, Inventors 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 :-
In gill Loxes of the ordinary construction used in the treatment of fibrous
materials the heckle bars are actuated by endless screws, provided with cams which
cause the heckle bars to rise and descend from one track to the other.
The present invention has for its object a method of actuating the heckle bars
without making use of the said screws. This is effected by a combination of wheel
gearing.
According to this invention the hecklebars are pressed close against each other
on the tracks, and they press upon each other without being able to become
displaced or disarranged in any way.
The two ends of these hecklebars lave the form of a cog or tooth and are so
arranged as to easily engage in the toothing of the cog wheels which cause them to
rise and fall.
Moreover according to this system, the wheels producing the rise and fall of the
heckle bars are screwed on to their axles, which enables them to be dismounted and
replaced with facility.
Referring to the accompanying drawings in which the various parts of the
apparatus are shown on a scale of one half full size.
Figure 1 is a side view and Figure 2 a front view.
A, transverse shaft like that usually employed in gill boxes. It actuates by suitable
gearing the shafts D, which bear at their ends the cam wheels C causing the
hecklebars B to rise from the lower tracks K to the upper tracks L On this
shaft D are moreover placed the wheels E actuating other wheels E¹. These last
actuate the shafts D¹ which bear on their other ends the cam wheels C' which cause
the hecklebars to descend from the upper tracks L to the lower tracks K.
S denotes two supports forming together the head of the gill box (Figure 2).
These supports carry all the pieces of the head and comprise especially;
1. The boxes in which the vertical axles H H revolve.
2. The tracks K and L constructed of steel or tempered iron; on these travel the
hecklebars B.
3. Two plates S¹ S₁ of tempered iron sustaining the shafts D and D¹ upon which
are screwed the spur wheels C and C¹.

page_text: 4. Two supports V W carrying a little shaft D¹¹ one part of which forms tho
endless screw F.
This screw F for which wheel gearing may be substituted if preferred, receives
the motion of the wheel work E by means of the intermediate piece El fixed on
the end of the said shaft D. This same screw actuates the vertical shaft H by
the pinion G. This shaft H bears at its upper part a pinion M which engages in
the species of rack formed by the ends of the hecklebars and which gives the
forward motion to these bars upon the upper track. The same shaft H. bears a
wheel J which actuates the shaft H', by means of a wheel work. J¹, fixed on this
last shaft. This shaft H¹ carries the pinion N which like the pinion M engages in
the lower rack, formed also by the ends of the hecklebars; the said pinion N
producing the return movement of the bars on the lower tracks. R R¹ Ru are
springs which as in ordinary.gill boxes assist the rise and the descent of the
hecklebars. O small rods of iron or steel fixed on the upper tracks to maintain the
hecklebars in position until the moment of their fall. P-pieces of iron or steel
which serve to guide the hecklebars when they mount from the lower to the upper
tracks. T is a guide for directing the material to be heckled to the teeth of the
beckle bars this guide which forms a part of every construction of gill box is fixed
on the two supports S.
As is obvious from the foregoing explanation the present invention possesses the
following advantages;
1. The endless screws which are done away with are much more costly to make
than the wheel gearing which replaces them.
2. The construction of the hecklebars with regular ends like cog wheel teeth is
less costly than the hecklebars as hitherto constructed.
There will thus be a considerable economy attainable in the construction of the
gill box. As has already been stated the hecklebars being pressed one against
another support each other, so that they cannot be either bent or broken by the
material under operation should this material contain lumps or hard or twisted
pieces.
In this system the cam wheels have
free from wear.
special form which renders them almost
They are preferably cast in steel or in malleable iron and tempered.
Moreover they are secured upon their axles by means of a screw thread which
enables them to be instantaneously dismounted or replaced.
If it be thought advisable to cause the heckling bars to come in contact with the
drawing cylinders, it is only necessary to substitute littlo supports fixed on the
sides of the principal supports S for the plates of tempered iron indicated by
the letter S¹.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, we declare that what
we claim is
The improvement in the construction of gill boxes consisting essentially in the
mechanism designed to replace the endless screws hitherto employed, substantially
as described and shown in the accompanying drawings.
