Year: 1853

page_text: LETTERS PATENT to Edward Davies, of Gothenburg, in the King-
dom of Sweden, Manufacturer, for the Invention of "IMPROVE-
MENTS IN MACHINERY OR APPARATUS FOR CARDING AND OTHERWISE
PREPARING COTTON OR OTHER FIBROUS MATERIALS TO BE SPUN, AND ALSO
FOR CLEANING OR STRIPPING CARDS USED IN THE SAID OPERATIONS."
Sealed the 5th December 1858, and dated the 30th June 1853.
PROVISIONAL SPECIFICATION left by the said Edward Davies
at the Office of the Commissioners of Patents, with his Petition,
on the 30th June 1853.
I, EDWARD DAVIES, do hereby declare the nature of the said Inven-
tion for "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR CARDING AND
OTHERWISE PREPARING COTTON OR OTHER FIBROUS MATERIALS TO BE SPUN,
AND ALSO FOR CLEANING OR STRIPPING CARDS USED IN THE SAID OPERATIONS,"
to be as follows:-
My Invention relates to improvements in the card and lap machines,
by which the card requires stripping, and I gain all the advantages of
a double carding engine in nearly the space of a single one, as I am

page_text: enabled to put about four times the quantity of sliver on my lap that
can be put in the best can now in use, and I put it on with a regulator
so that the sliver is never stretched.
By reference to the accompanying two Sheets of Drawings it will be
seen that I place a roller or small cylinder under or beneath the main
cylinder in front of the carding engine, and also a small cylinder be-
hind the main cylinder, with two rollers and two clearers for opening the
cotton previous to going to the main cylinder.
The second Sheet of Drawings shews my improved lap machine,
which I place in front of the carding engine, with a regulator to pre-
vent the stretching of the sliver, which also enables me to dispense
with cans, coilers, or plungers, and put on considerably more weight
on each lap.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Edward Davies in the Great Seal Patent Office,
on the 27th December 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
EDWARD DAVIES, of Gothenburg, in the Kingdom of Sweden, Manu-
facturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent, bearing date the Thirtieth day of June, in the
year of our Lord One thousand eight hundred and fifty-three, in the
seventeenth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Edward Davies, Her especial
licence that I, the said Edward Davies, my executors, administrators,
and assigns, or such others as I, the said Edward Davies, my execu-
tors, administrators, and assigns, should at any time agree with, and
no others, from time to time and at all times thereafter 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 "IMPROVE-
MENTS IN MACHINERY OR APPARATUS FOR CARDING AND OTHERWISE PREPARING

page_text: COTTON OR OTHER FIBROUS MATERIAL TO BE SPUN, AND ALSO FOR CLEANING
OR STRIPPING CARDS USED IN THE SAID OPERATIONS," upon the condition
(amongst others) that I, the said Edward Davies, by an instrument
in writing under my hand and seal, 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 imme-
diately after the date of the said Royal Letters Patent.
NOW KNOW YE, that I, the said Edward Davies, do hereby
declare the nature of my said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained
in and by the following statement (that is to say):
My Invention relates, firstly, to improvements in the arrangement
and construction of the carding engine, by which I gain all the advan-
tages of a double carding engine in nearly the space now occupied
by a single one, and I dispense entirely with the operation of stripping
the card by hand. Secondly, in the arrangement and construction of
the lap machine, by which I am enabled to put about four times the
quantity of sliver on the lap that can be put in the best can now in
use, and by means of an apparatus or regulator attached to the lap
machine I prevent the stretching of the sliver. To accomplish these
objects I place a roller or small cylinder behind the main drum or
cylinder with two rollers and two clearers for opening the cotton or
material previous to its going to the main drum or cylinder, and an
additional roller or cylinder under the doffer which constitutes a self-
acting stripper. My improvements in the lap machine consist of a self-
acting regulator to prevent the stretching of the sliver, and which
enables me to dispense entirely with cans, coilers, and plungers, and
also to put considerably more weight on cach lap. These my said
improvements will be clearly understood by reference to the accompany-
ing two Sheets of Drawings, in which the same letters of reference are
used to represent similar parts where different views or diagrams are
shewn. In Sheet 1, Fig. 1, is a side elevation of a carding engine, with
the side plate frame off, shewing the position of the additional small

page_text: cylinder behind the main cylinder or drum, with the two rollers and
clearers, and also shewing the additional roller or cylinder under the
doffer, for the purpose. of stripping the card with a smaller cylinder or
urchin to assist in the said process. Figs. 2, and 3, are sectional eleva-
tions of the same, shewing the working parts of the engine more in
detail, all of which are easily understood by persons conversant with
spinning machinery. a, represents: the lap roller with the cotton or
material on it as received from the blowing or lap machine; b, b, the
feed rollers; c, and d, the rollers usually employed for conveying the
cotton or material from the feed rollers to the main drum or cylinder;
e, my additional roller with the two smaller rollers and clearers for
opening the cotton or material previous to its going 'to the main drum
or cylinder; f, the usual rollers, cylinders, or conductors; g, the doffer;
h, my additional roller or cylinder under the doffer for stripping the
card; and, the smaller cylinder or urchin for assisting in the said
process. In Sheet 2, Fig. 1, is a front elevation of a lap machine,
shewing my improved regulator for preventing the .stretching of the
sliver; and Figs. 2, and 3, are right and left hand end views of the
same. a, represents the lap roller revolving on its axes above the
fluted roller b; c, the tube through which the sliver passes, the end of
the said tube pressing the sliver on the lap roller; d, a lever attached
to the wheel e, and slide f, so that by the revolutions of the wheel e,
the said lever draws the slide f, giving it a lateral motion backwards
and forwards with the assistance of the weight chain and pully g, thus
regulating the delivery of the sliver and preventing it being stretched.
Having thus fully described the nature and particulars of my said
Invention, I desire it to be distinctly understood that I do not confine
myself to the exact details herein described, as such may be varied or
modified without departing from the principle thereof. But I claim as
of my Invention, and which, to the best of my knowledge and belief,
has not been hitherto used within this realm firstly, thearrangement
and construction of the carding engine, with the additional smaller
cylinder, rollers, and clearers, with the self-acting stripping roller. And,
secondly, the lap machine, with the regulator, to prevent the stretching

page_text: of the sliver, as all of which improvements are herein described and
illustrated in the accompanying two Sheets of Drawings.
In witness whereof, I, the said Edward Davies, have hereunto set
my hand and seal, this Third day of October, One thousand
eight hundred and fifty-three.
Signed, sealed, and delivered by
the within named Edward
Davies, in the presence of
E. J. HUGHES,
Patent Agent,
