Improvements in Preparing Frames Employed in the Manufacture
of Fibrous Materials.
I SAMUEL DYER of 135 Grosvenor Street in the Borough of Beltast and County
of Antrim, in Ireland, Flax Mill Manager do hereby declare the nature of this invention
to be as follows:-
The object of my invention is to provide means of keeping the rollers of Spreading,
Drawing and Roving Frames, employed in the manufacture of fibrous materials such
as flax, hemp, jute, tow and cotton, clean and free from collections of flowings and
laps or loose fibres and rubber pickings which become disengaged from the sliver in
the process technically known as preparing.
For this purpose, in addition to the ordinary rubber of the Spreading, Drawing and
Roving Frames, I attach to the rubber rod of the Frame a bracket carrying a small
cylindrical rubber which impinges upon the roller and is made by it to revolve at a
high speed and catch the flowings which drop off the ordinary rubber when it is lifted
up to be cleaned. I form the bracket with a slot so that the rubber will accommodate
itself to every size of roller and may be removed from the bracket when requiring to
be cleaned. And I further provide the Drawing and Roving Frames with a
rubber which i place underneath the back pressing or jockey rollers and between the
back rollers of such Frames. This rubber is held in position by springs and brackets
attached to the Frames and may be stationary or made to revolve, according to will.
The action of this rubber prevents the sliver laps from collecting upon the back
pressing or jockey rollers and from making the circumferences thereof unequal, so
that portions of the sliver run in slack to the Gills and cause unevenness in the yarns,
and ruffling and tossing of the sliver by frequent cleanings is thereby avoided.

Improvements in Preparing Frames Employed in the Manufacture
of Fibrous Materials.
I, SAMUEL DYER of 135 Grosvenor Street in the Borough of Belfast and County of
Antrim in Ireland, Flax Mill Manager, 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:―
The object of my invention is to provide means of keeping the rollers of Spreading,
Drawing and Roving Frames employed in the manufacture of fibrous materials, such
as Flax, Hemp, Jute, Tow and Cotton, clean and free from collections of flowings and
laps or loose fibres and rubber pickings which become disengaged from the sliver in
the process technically known as "Preparing."
For this purpose, in addition to the ordinary rubber of the Spreading. Drawing and
Roving Frames, I attach to the rubber rod of the Frame brackets carrying small
cylindrical rubbers which impinge or press upon the wood pressing rollers and are
made by them to revolve at a high speed and to catch the flowings which drop off the
ordinary rubber when it is lifted up to be cleaned.
I form each bracket with a slot so that the cylindrical rubbers will accommodate
themselves to every size of roller and may be removed from the brackets when
requiring to be cleaned.
I may, however, dispense altogether with the use of the ordinary rubber heretofore
employed and keep the Rollers clean and free from flowings and laps or loose fibres
by the use of the cylindrical rubbers only.
I also in like manner attach a cylindrical rubber to the brackets which carry the
iron pressing roller of a Spreading or a Drawing Frame.
or
I further provide the Drawing and Roving Frames with a rubber which 1 place
underneath the back pressing or jockey rollers and between the back rollers of such
Frame. This rubber is held in position' in close contact with the back pressing or
jockey rollers by springs and brackets attached to the Frames and it may be stationary
dead" or may be made to revolve, according to will, by means of a friction boss
or other ordinary mechanical agency. The action of this rubber prevents the sliver
laps from collecting upon the back pressing or jockey rollers and from making the
circumferences thereof unequal so that portions of the sliver would run in slack to the
gills and cause unevenness in the yarns; and ruffling and tossing of the sliver by
frequent cleanings is thereby avoided.
And in order that my said invention may be more fully understood I shall now
proceed to refer to the drawings upon the sheet hereunto annexed, the same letters of
reference indicating the same or corresponding parts of my apparatus throughout all
the figures.
Fig. 1. is an end elevation of part of a Drawing Frame shewing (with some
ordinary parts) a slotted bracket attached to the rubber-rod and carrying a cylindrical
rubber which impinges or presses upon a wood pressing roller, and also a slotted
bracket attached to a bracket bearing the iron pressing roller and carrying a cylindrical
roller which impinges or presses upon the iron pressing roller.

page_text: Fig. II. is a front elevation showing part of an ordinary rubber and two slotted
brackets carrying a cylindrical rubber between them; also a wood pressing roller.
Figs. III. & IV. are an end and a front view respectively of a slotted bracket to be
attached to the rubber rod of the frame.
Fig. V. is a front view of a cylindrical rubber to be carried from the rubber rod.
Fig. VI. is a front elevation of an iron pressing roller and of slotted brackets
carrying a cylindrical rubber which impinges or presses upon it.
Fig. VII. is a front view of the cylindrical rubber shewn in Fig. VI.
Figs. VIII. & IX are an end and a front view respectively of the slotted brackets
shewn in Fig. VI.
Fig. X. is a back view of the back pressing or jockey rollers and the screw brackets
of a Drawing or Roving Machine, showing a stationary rubber held in position
against the back pressing or jockey rollers by springs and brackets.
Fig. XI. is an end view of a screw bracket and of the back rollers, shewing the
stationary rubber held in position against a back pressing or jockey roller by a
bracket and spring; and
Figs. XII & XIII are a back and an upward view respectively of the stationary
rubber. a is a slotted bracket; is a cylindrical rubber; c is a wood pressing
roller is an iron pressing roller; e, e are back pressing or jockey rollers; is a
stationary rubber; g, g are brackets and h, h are springs for holding the stationary
rubber,, in contact with the roller.
Having now particularly described and ascertained the nature of my inven
tion and in what manner the same is to be performed I declare that what
I claim is
1. The use, in Preparing Frames employed in the manufacture of fibrous materials,
of a cylindrical rubber supported in a desired position on slotted brackets substantially
in the manner and for the purposes hereinbefore described and shewn in the drawings
hereunto annexed.
2. The use, in Spreading, Drawing and Roving Frames employed in the manu-
facture of fibrous materials, of cylindrical rubbers supported on slotted brackets and
maintained in contact with the wood pressing rollers of such Frames substantially in
the manner and for the purposes horeinbefore described and shewn in the drawings
hereunto annexed.
3. The use, in spreading and Drawing Frames employed in the manufacture of
fibrous materials, of a cylindrical Rubber supported on slotted brackets and maintained
in contact with the iron pressing Rollers of such frames substantially in the manner
and for the purposes hereinbefore described and shewn in the drawings hereunto
annexed.
4. The use, in Drawing and Roving Frames employed in the manufacture of fibrous
materials, of a stationary or revolving Rubber supported and operating substantially
in the manner and position and for the purposes hereinbefore described and shewn in
the drawings hereunto annexed; and
5. The several and respective combinations and arrangements of parts constituting
my Rubbing Apparatus above mentioned constructed and employed substantially
in the manner and for the purposes hereinbefore described and illustrated by the
drawings hereunto annexed.
