of Lancaster, Clerk, for the Invention of "AN IMPROVEMENT IN OR
ADDITION TO ROLLERS EMPLOYED IN SPINNING."
PROVISIONAL SPECIFICATION left by the said Wilhelm Dreschfeld
at the Office of the Commissioners of Patents, with his Petition, on the
26th January 1856.
I, WILHELM DRESCHFELD, of Manchester, in the County of Lancaster,
Clerk, do hereby declare the nature of the said Invention for "AN IMPROVE-
MENT IN OR ADDITION TO ROLLERS EMPLOYED IN SPINNING," to be as follows:-
The object of this Invention is to prevent waste of fibre and "roller laps,"
and to keep the rollers clean.
The Invention consists in adapting to the upper or under roller, a shield or
apron, lined or not on one side with a piece of cloth or other suitable material.
This shield or apron comes in contact with the roller, keeps it clean, and
prevents the vibration or agitation of the air acting upon the filamentous.
substances operated upon.
From rapid rotation of rollers or cylinders, air in their immediate vicinity

page_text: is set in a state of vibration or agitation, and in the case of rollers employed
in spinning machinery, this action of the air has a tendency to raise the fibres
of the filamentous substances operated upon, on account of their great
lightness. By degrees these fibres get hold of the upper roller, become fixed,
and ultimately form waste. Frequently a number of these fibres become
grouped together, and form laps upon the roller. The shield or apron
prevents the agitation of the air being communicated to the fibres, consequently
waste and lapping are avoided.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Wilhelm Dreschfeld in the Great Seal Patent Office on
the 26th July 1856.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILHELM
DRESCHFELD, of Manchester, in the County of Lancaster, Clerk, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-sixth day of January, in the year of our
Lord One thousand eight hundred and fifty-six, in the nineteenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Wilhelm Dreschfeld, Her special licence that I, the said Welhelm
Dreschfeld, my executors, administrators, and assigns, or such others as I, the
said Wilhelm Dreschfeld, my executors, administrators, and assigns, should at.
any time agree with, and no others, from time to time and at all times there-
after during the term therein expressed, should and lawfully might make,
use, exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for "AN IMPROVE-
MENT IN OR ADDITION TO ROLLERS EMPLOYED IN SPINNING," upon the condition
(amongst others) that I, the said Wilhelm Dreschfeld, my executors or
administrators, by an instrument in writing under my, or their, or one of
their hands and seals, should particularly describe and ascertain the nature.
of the said Invention, and in what manner the same was to be performed,
and cause the same to be filed in the Great Seal Patent Office within six
calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said Wilhelm Dreschfeld, do hereby declare.
the nature of my said Invention, and in. what manner the same is to be

page_text: performed, to be particularly described and ascertained in and by the following
statement thereof, reference being had to the Drawings hereunto annexed,
that is to say-
The object of this Invention is to prevent waste of fibre and "roller laps,"
and to keep rollers clean.
The Invention consists in adapting to the upper or under roller, or to any
roller employed in spinning machinery, a shield or apron, covered or not on
one side, or on all the sides, with a piece of cloth, cork, wood, or other
suitable material. This shield or apron comes in contact with the roller, keeps
it clean, and prevents the vibration or agitation of the air acting on the
filamentous substances operated upon. From rapid rotation of rollers or
cylinders, air in their immediate vicinity is set in a state of vibration or
agitation, and in the case of rollers employed in spinning machinery, this
action of the air has a tendency to raise the fibres of the filamentous sub-
stances operated upon on account of their lightness. By degrees the fibres get
hold of the roller, become fixed, and ultimately form waste. Frequently a
number of these fibres become grouped or clustered together, and form laps
on the roller. Now, my shield or apron prevents the agitation of the air
being communicated to the fibres, and waste and lapping are consequently
avoided.
Figures 1, 2, 3, 4, and 5 of the Drawings annexed shew various descriptions
of shields or aprons adapted for carrying my Invention into effect. In
Figure 1 (elevation) and Figure 2 (end view), the shield A is sloped off to a
thin edge a, which is the part in contact with the roller. In Figure 3
(elevation) and Figure 4 (end view) the part b, which comes in contact with
the roller, is not a sharp edge as in Figure 1, but is hollowed, and forms a
smooth surface against which the face of the roller works. A, Figure 5,
is a shield formed with a recess adapted for a double roller, or roller in two
parts, of the description shewn. A is the shield; B, the roller; e, the recess
in the shield. Figure 6 shews a shield partially covered with cloth. The
shield or apron is connected to the roller, to the axis of the roller, or to
the machinery, in any suitable manner, and it may be either a fixture or
removeable. For example, if removeable, it may be hooked on the roller
by hooks attached to it as at d, d, Figure 5, or it may be suspended by
eyes to hooks placed on the machine, or fixed to the frame of the machine
by screws.
And having now described the nature of my said Invention, and in what
manner the same is to be performed, I declare that I claim, the employ-

page_text: ment of a fixed or removeable shield or apron adapted to rollers employed in
spinning machinery, for preventing waste of fibre and roller laps, and for
keeping the rollers clean.
In witness whereof; I, the said Wilhelm Dreschfeld, have hereunto set
my hand and seal, the Eleventh day of July, One thousand eight
⚫ hundred and fifty-six.
WILHELM DRESCHFELD: (L.S.)
