HENRY JENKINSON, of Salford, in the County of Lancaster, Machine Maker,
and THOMAS PRIESTLEY, of Shuttleworth, in the same County, Manager, send
greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of the United of Great Britain
and Ireland, bearing date at Westminster, the Twelfth day of December
(One thousand eight hundred and forty-nine), in the Thirteenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the
said John Henry Jenkinson and Thomas Priestley, our exors, admors, and
assigns, Her especial license, full power, sole privilege and authority, that
we, the said John Henry Jenkinson and Thomas Priestley, our exors, admors,
and assigns, or such others as we, the said John Henry Jenkinson and Thomas
Priestley, our exors, admors, or assigns, should at any time agree with, and no
others, from time to time and at all times during the term of years therein
expressed, 'should and lawfully might make, use, exercise, and vend, within
England, Wales, and the Town of Berwick-upon-Tweed, our Invention of
"CERTAIN IMPROVEMENTS IN MACHINERY OR APPARATUS TO BE USED FOR PREPARING,
SPINNING, AND DOUBLING, COTTON, WOOL, FLAX, SILK, AND SIMILAR FIBROUS
MATERIALS;" in which said Letters Patent is contained a proviso that we,
the said John Henry Jenkinson and Thomas Priestley, or one of us, shall
cause a particular description of the nature of our said Invention, and in what
manner the same is to be performed, by an instrument in writing under our
hands and seals, or under the hand and scal of one of us, to be inrolled in
Her Majesty's High Court of Chancery within six calendar months next and

page_text: immediately after the date of the said in part recited Letters, as in and by
the same, reference being thereunto had, will more fully and at large
appear.
NOW KNOW YE, that in compliance with the said proviso, we, the said
John Henry Jenkinson and Thomas Priestley, do hereby declare the nature
of our Invention to consist:-
First, in an improved arrangement of machinery applied to mules, billies,
stretchers, and similar machines for scavenging or cleaning the top-board of the
carriage and the front of the roller beam simultaneously or in succession, by
means of a revolving, traversing, and oscillating roller applied to each.
rollers attached.
In drawing No. Figure 1 represents a front elevation of a mule carriage
and roller beam. Figure 2 a transverse section of the same, with the dirt
Figure 3 the dirt rollers on a larger scale, the dark blue
and pink coloured circles representing some of the various positions which the
said rollers a¹ and a assume during operation; and Figure 7 a plan of the
dirt roller. A is the roller beam; B the top board of the mule carriage. a¹
and a are the dirt rollers, made of tin or other suitable material, and covered
with felt or flannel. Their axes are placed in openings in the bars So as
to enable the rollers to revolve freely in them; these bars 6 pass through
openings in the brackets c, in which they traverse up and down, and oscillate
outwards and inwards to a small extent.
In Figure 2 a carriage is shown receding from the roller beam; and as the
roller a rests upon and is at this period of the operation supported by the
top board, it is thereby caused to revolve and descend down the inclined top
board, the dirt on which adheres to the roller cover, and at the same time the
roller a', being in contact with the roller beam, and being made to revolve by
means of the pullies d', ds, and strap d³ (see Figure 1), thereby collects the
dust from that beam, and when the carriage goes in these rollers are raised
and turned by the means before described.
In Figure 7, c is one of the brackets attached to the roller beam. 6 is one
of the bars which carry the dirt rollers; this bar is made to fill the slot or
opening in the bracket in the direction of the black line, so that it may
traverse up and down without any lateral motion, but as it does not entirely
fill the slot or opening in the direction of the red line, the rollers oscillate to
and from the roller beam.
In regard to this portion of our Invention, we do not claim any of the parts
separately which are shewn and described; but we do claim the improved
arrangement of the parts whereby the roller a² rises in the slots c, c, and allows
the rollers a' and a to accommodate themselves to the increasing size as the

page_text: dirt collects, and the application of these parts to such machines as we have
shown and described for scavenging and cleaning the carriage tops and roller
beams.
Secondly, in raising the finished cops partially off the spindles on which they
are made by mechanical means, instead of performing this operation by manual
labour, which was the only plan in use prior to our Invention.
In Drawing No. 1, and in Figures 1 and 2, e is a plate or strip of metal
extending the whole length of the carriage (which we call a comb' plate);
having slots in it, one for each spindle; each slot embraces three sides of the
spindle within it below the cop, so that when this plate is raised the cops are
necessarily raised with it; a plate with a straight edge may be made to
answer the same purpose. The plate e is fixed to the rack f, which takes into
the pinions f¹ keyed on the shaft, on which is also fixed the worm sector f³,
to which motion is given by the worm and winch f*, thus imparting a vertical
or lifting motion to the rail e, and thereby to the cops y.
In regard to this portion of our Invention, we do not claim any of the parts
separately which we have shewn and described; but we do claim as our
Invention the raising of the cops partially off the spindles on which they arò
formed by mechanical means instead of by hand as heretofore.
.
Thirdly, in weighting the front top rollers of preparation and spinning
machines on their upper surface by placing weights thereon, which we prefer
to be in the form of rollers, so that they may revolve, and thereby avoid as
much friction as possible, and that they may also act as clearer rollers.
In Drawing 1, and in Figures 4 and 5, are represented these our improve
ments, Figure 4 being a transverse section, and Figure 5 a longitudinal eleva-
tion of parts of one of these machines. 9, are the top weights formed into
rollers, which rest, and revolve freely upon the ordinary front top rollers h, and
they are kept in their places by short axes working in slots, as shown in the
Drawing. By covering these weights with flannel they also act as clearers.
In Figure 6 is represented one of the old ways of weighting a front top
roller by a weight suspended from its axes. Figures 4 and 5 show the
revolving weight as applied only to the front top rollers of mules or
throstles.
In this portion of our Invention we do not claim any of the separate parts
we have shown and described, nor the application of revolving weights when
used on any other than the front top rollers; but we do claim as our Invention
weighting the front top rollers of preparation and spinning machines by a
weight resting upon the upper surface of what are now ordinarily called the
front ton rollers.

page_text: Fourthly, in a novel arrangement and application of machinery to carding
engines and drawing frames, for stopping their action when a sliver breaks.
In Drawing No. 2, and in Figures 7, 8, 9, and 10, our new arrangement of
parts forming a stop motion is shown applied to a drawing frame between the
front delivering rollers and the delivering blocks (we have also shown the well-
known stop motion at the back of the frame). a represents the trumpet
mouth; 6 an elbow lever carrying a rod c. This rod at its lower end carries

trumpet mouth, when in a position for working, as shown in Figure 7, is so
nearly balanced as to be kept in that position whilst the whole of the slivers
are passing through it, by the friction and pressure they exert upon it; but if
any one of the slivers breaks, the trumpet mouth falls, owing to the diminution
pressure, and the weighted lever also falls, and turns the shaft f, upon
which it is fixed, partially round, so that the fingers g, which are also fixed to
this shaft, come in contact with the vibrating bars h of the well-known stop
motion, and thereby stop the machine.
of
When this stop motion is applied to a carding engine, a slight variation of
this arrangement is necessary, which any competent workman can supply.
In this portion of our Invention we do not claim any of the parts separately
which we have shown and described; but we do claim the combination of
parts we have shown forming the stop motion when placed between the front
drawing rollers and the delivering blocks, or any similar combination. And we
also claim the use of a stop motion to carding engines when actuated by the
trumpet mouth or guide of the sliver.
Fifthly, in a new manufacture of driving pullies to be used in preparation,
spinning, doubling, and winding machines. These driving pullies we make
by forming a short portion of a cylinder on a disc by pressing, stamping, bend-
ing, or by the means sometimes called spinning, tin, sheet iron, or other thin
plates of malleable metal, and uniting such a disc in the centre to a boss by
solder or any other suitable means, so that thereby the friction pulley so formed
can be fixed upon an axis.
In regard to this portion of our Invention, we do not claim any separate
part of the pulley, nor the mode of uniting the two parts together; but what
we do claim is, the application to the wharves of spindles or bobbins friction
pullies, made as aforesaid, for driving them by contact when used in such
machines as we have described.
And, lastly, in the novel application of one or more scavenging or dirt
rollers to the under side of the traversing carriage of preparation and spinning
machines, which rollers rest and roll upon the floor, and, being covered with

page_text: flannel or felt, or such other substance, collect the dirt upon them by rolling
backwards and forwards.
In this portion of our Invention we do not claim any of the parts separately,
but we do claim attaching to such preparation and spinning machines as have
traversing carriages one or more dirt rollers, which rest upon the floor and
collect the dust from the part over which they roll.
In witness whereof, I, the said John Henry Jenkinson, have hereunto
set my hand and seal, this Twelfth day of June, in the year of our Lord
One thousand eight hundred and fifty.
