I, JULES DEVALLÉE, of 60, Rue Watt, Roubaix, in the Republic of France,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in gill-frames or spreaders for treating
flax or the like.
In gill-frames or spreaders as heretofore generally constructed the shafts of the
screws for operating the gills or heckle-bars are extended back to the main driving
gear of the machine and are rotated directly by means of spur gearing. By
reason of this arrangement the shaft with the upper pair of screws must be of
considerable length whereby it is awkward and difficult to mount and dismount
the same, and, as the screws and the combs must be very often separated from
one another, this entails expenditure of time and money which has been found of
great disadvantage.
Now, in order to obviate this disadvantage, I arrange the intermediate gearing
for the screws at the end of the latter next to the drawing rollers. By this con-
struction I am enabled to mount the upper screws on short shafts or studs so that
the said screws are very light and can be, together with the gills or heckle-bars,
easily removed and cleaned.
I am also enabled by my improvements to remove or exchange the feed
cylinders without having to remove the screws and the latter can be removed and
replaced without the necessity of lifting off the feed cylinders.
The bearings or the attachment of the studs or shafts of the screws, comprise a
plate arranged at the ends of the screws opposite to the spur gear. The said spur
gear can be enclosed, if desired, in a casing or plate of suitable shape.
In a machine of ordinary construction, for the purpose of cleaning etc., the
gills and the feed cylinders with the whole of the driving gear must be removed
whilst with my arrangement only the screws need to be unscrewed to give access
to the gills.

I, JULES DEVALLÉE, of 60, Rue Watt, Roubaix, in the Republic of France,
Engineer, do hereby declare the nature of this invention and in what manner the
Price 8d1

page_text: same is to be performed, to be particularly described and ascertained in and by
the following statement:-
This invention relates to improvements in gill-frames or spreaders for treating
flax or the like.
In the accompanying drawings:-
Figure 1 represents a sectional elevation and a part plan of a gill-frame or
spreader of ordinary construction.
Figures 2 and 3 are sectional elevations of gill-frames or spreaders made
according to my invention.
Figure 4 is a plan of a machine of ordinary construction.
Figure 5 is a similar view of a gill-frame or spreader made according to my
invention.
In gill-frames or spreaders as heretofore generally constructed the shafts d
(see Figure 1 of the drawing) of the screws for operating the gills or heckle-
bars are extended back to the main driving gear of the machine and are rotated
directly by means of spur gearing a. By reason of this arrangement the shafts d
with the upper pairs of screws must be of considerable length so that it is awkward
and difficult to mount and dismount the same and, as the screws and the combs
must be very often separated from one another, this entails expenditure of time
and money which has been found of great disadvantage.
Now, in order to obviate this disadvantage, I proceed as shewn in Figures 2
and 3, that is to say, I arrange the intermediate gearing a for the screws c¹, c
and at the end of the latter next to the drawing rollers. By this construction
I am enabled to mount the upper screws on short shafts or studs & so that the
said screws are very light and can be, together with the gills or heckle-bars,
easily removed and cleaned.
I am also enabled by my improvements to remove or exchange the feed
cylinders A without having to remove the screws and the latter can be removed
and replaced without the necessity of lifting off the feed cylinders.
The bearings or the attachments of the studs or shafts of the screws, comprise
a plate arranged at the ends of the screws opposite to the spur gear a. The said
spur gear a can be enclosed, if desired, in a casing or plate of suitable shape.
In a machine of ordinary construction, as shewn in Figure 1, for the purpose
of cleaning etc., the gills the feed cylinders A with the whole of the driving gear
must be removed whilst with my arrangement as shewn in Figure 5 only the
screws need to be unscrewed to give access to the gills. A comparison of the
construction shown in the two figures will clearly shew the important result
obtained by my invention.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:
A gill-frame or spreader wherein the gearing for the screws operating the gills
is secured to the ends of the screws next the drawing rollers and wherein the
shafts of the screws are so shortened that they only require one bearing
immediately behind the screws, substantially as, and for the purposes, hereinbefore
described.
