PROVISIONAL SPECIFICATION left by the said John Walker & Thomas
Green. Beaumont at the Office of the Commissioners of Patents on the
21st March 1883.
JOHN WALKER and THOMAS GREEN BEAMONT [sic] of Dewsbury Mills in the
County of York. "IMPROVEMENTS IN AND APPLICABLE TO "LAP" FORMING
MACHINES FOR FEEDING WOOL AND OTHER FIBRES TO CARDING MACHINES
Our Invention has reference to that class of machine known by the name of
Marsden and Blamires' feeding Machine; but our Improvements are applicable to
other lap machines where the lap is formed by the reciprocatory motion of a
carriage
The first part of our Invention consists in a new combination and arrangement
of apparatus for giving the necessary to and fro motion to the carriage; and this
we accomplish by means of a connecting rod, one end of which is attached to the
carriage and the other end to an endless travelling chain which imparts the
necessary to and fro motion to the carriage
The endless chain, which is driven by means of a toothed wheel, passes over and
around adjustable pullies, and it is kept at a suitable tension by an adjustable
wheel
By the employment of this form of apparatus, the rack and pinion at present
employed for giving reciprocatory motion to the carriage are dispensed with,
whereby we are enabled to run the carriage and last doffer in the scribler machine
very much quicker, consequently the layers or films of fibre are thinner, producing
a "lap" of the same weight of a greater number of layers than is now the case,

page_text: the advantage of which is to produce better carding as is well understood by
practical carders and spinners
As the distance travelled by the carriage varies according to the class of the
fibre operated upon, the length of stroke given to the said carriage can be regulated
to the greatest nicety by removing or adding more links to the chains and adjusting
the rollers
Secondly. Our Invention relates to the means of operating the cuttling or
reversing rollers each time the carriage arrives at the end of its traverse and this
we effect by connecting a lever to some convenient part, so that on being moved
sideways it comes into contact with the bracket carrying the cuttling rollers.
We also attach to each side of the carriage adjustable stop pieces which come into
contact with the said lever, tilting it sideways at the end of each stroke thereby
reversing the rotary motion of the cuttling rollers.

JOHN WALKER and THOMAS GREEN BEAUMONT of Dewsbury Mills in the County
of York " IMPROVEMENTS IN AND APPLICABLE TO "LAP" FORMING MACHINES FOR
FEEDING WOOL AND OTHER FIBRES TO CARDING MACHINERY"
Our Invention has reference to that class of machine known by the name of
Marsden and Blamires' feeding machine, but our Improvements are applicable to
other lap machines where the "lap" is formed by the reciprocatory motion of the
carriage.
The first part of our Invention consists in a new combination and arrangement
of apparatus for giving the necessary to and fro motion to the carriage; and this
we accomplish by means of a connecting rod, one end of which is attached to the
carriage and the other end to an endless travelling chain which imparts the
necessary to and fro motion to the carriage.
In order that our Invention may be better understood, we herein give reference
to the accompanying sheets of Drawings, wherein Figs 1 and 2 are side elevations
of such parts of a scribbling machine and lap forming apparatus as are necessary
to shew the application of our Improvements. Fig 3 is an illustration of Figs 1
and 2 combined. A is framing of the scribbling machine having cylinder B and
doffer C arranged in the usual manner. The lap forming apparatus is shewn at
Fig 2 and is that constructed on the principle and known by the name of Marsden
and Blamires' feeding machine, which is so well understood and forming no part of
our Invention, it is not necessary to describe it in this Specification; our Invention.
being simply in the means or method of imparting to it the necessary reciprocatory
motion for forming the laps, and this we accomplish by means of the endless
chain D and connecting rod E, the latter being connected to the chain by bolt at
the part F and to the lap forming machine at the part G.
The endless chain D which is driven by means of a toothed wheel H, passes
over and around adjustable pullies I and J and the said chain is kept at a suitable
tension by an adjustable toothed wheel K. The toothed wheel H receives its
rotary motion from the swift, doffer or other going part of the scribbling machine
as is found most convenient. By the employment of this form of apparatus, the rack
and pinion at present employed for giving reciprocatory motion to the carriage, are
dispensed with, and the great wear and tear occasioned thereby is avoided; we are
also enabled to run the carriage and lost doffer in the scribbler machine very much
quicker, consequently the layers or films of fibre are thinner, producing a "lap" of the
same weight of a greater number of layers than is now the case, the advantages
of which are to produce better carding as will be well understood by practical
carders and spinners. As the distance travelled by the carriage varies according
to the class of fibre operated upon, the length of stroke given to the said carriage
can be regulated to the greatest nicety by removing or adding more links to the
chain and adjusting the rollers I, J and K.
Secondly. Our Invention relates to the means of operating the cuttling or
reversing rollers each time the carriage arrives at the end of its traverse; and this
we effect by connecting a lever to some convenient part so that on being moved
sideways it comes into contact with the bracket carrying the cuttling rollers.
We also attach to each side of the carriage, adjustable stop pieces which come into
contact with the said lever, tilting it sideways at the end of each stroke, thereby
reversing the position of the cuttling rollers."

page_text: This part of our Invention is shewn at Fig 2, where L and M are the cuttling
rollers connected at each end to oscillatory brackets N, working upon the fulcrum P,
whilst the shafts or bosses of the said rollers nove within the curved slots Q each
time they are moved sideways for reversing their position.
The slots are formed in the frame R and to this frame, we atttach the lever S
provided with a slot at its upper end, into which enters a pin T projecting from
the oscillatory bracket N. At each side of the lap forming carriage we fix
adjustable stop pieces U, which at each inward or outward movement of the
carriage strikes the bottom point of the lever S, tilting it sideways as shewn in the
drawings, first on one side and then on the other side, whereby the position of the
cuttling rollers are reversed. Two flat springs V. are provided for holding the
bracket in position until the rollers are reversed. Fig 4 shews how the cuttling
rollers may be reversed by the fixing W being placed on the bracket N.
t
Having now shewn and described our Invention and the manner in which the
same is to be performed, we would have it understood that we do not confine
ourselves to the exact details herein shewn and described as they may be varied
without departing from the main features thereof, nor do we confine ourselves to
the driving of a Marsden and Blamires' "lap" forming machine, as our Improve-
ments are equally applicable to other descriptions of such machines where a
reciprocatory motion is necessary to form the laps, what therefore we claim is
Firstly. The endless chain Ď operated in the manner and for the purposes
substantially as herein shewn and described.
Secondly. The adjusting rollers for adjusting and regulating the tension of the
endless chain.
Thirdly. The means and method herein shewn and described for tilting and
reversing the cuttling rollers in .manner substantially as herein shewn and
described.

In witness whereof, we, the said John Walker and Thomas Green Beaumont
have hereunto set our hands and seals this seventeenth day of September in the
year of our Lord, One thousand eight hundred and eighty three.
