IMPROVEMENTS IN CONDENSER CARDING ENGINES
Year: 1877

page_text: LETTERS PATENT to James Bragg, of Buckfastleigh, in the, County of Devon,
Foroman in a Woollen Factory, for the Invention of "IMPROVEMENTS IN
CONDENSER CARDING ENGINES."
Sealed the 15th September 1877, and dated the 22nd March 1877.
PROVISIONAL SPECIFICATION left by the said James Bragg at the Office of
the Commissioners of Patents on the 22nd March 1877.
JAMES BRAGG, of Buckfastleigh, in the County of Devon, Foreman in a Woollen
Factory. IMPROVEMENTS IN CONDENSER CARDING ENGINES."
"
Firstly. My Invention consists in the employment of three or more "doffer"
cylinders arranged in any convenient position; by employing three or any number
of doffers I am enabled to greatly increase the number of threads to be taken from
the "swift" of condensor, and the space between the rings of the doffer cylinder can
also be increased. I purpose employing the usual rubbing leather, or if preferred,
twist straps of leather or any convenient material.
Secondly. My Invention consists in the application of a spinning or winding
process to the condensor.
Thirdly. My Invention consists in an improved mechanical arrangement by
which the whole of the "condensor machine" following the "doffer" cylinders can
be removed.
By fixing to the condensing machine four or any convenient number of wheels to
run on two rails, one on each side, the condensing machine can then be wheeled
back, leaving the doffers behind, so that the cylinder and doffers as well as the
condensing parts can then be more readily and conveniently examined or repaired
than in the ordinary fixed frame now employed, thereby greatly minimising the
labour and time connected therewith.

page_text: Firstly. My Invention consists in the employment of three or more “doffer
cylinders arranged in any suitable position. By employing three or any other
convenient number of doffers I am enabled to greatly increase the number of threads
to be taken from the swift of condenser, and the spaces between the rings of the
"doffer" cylinders are also increased, and this I am enabled to do without
diminishing the usual number or reducing the size of workers, &c., on the carder.
Secondly. My Invention consists in an improved mechanical arrangement by
which the whole of the condensing machine following the "doffer" cylinders can be
easily removed.
By fitting to the condensing machine four or any other suitable number of wheels
to run on two pieces of flat iron let into the floor, that is to say, one on each side,
the condensing machine can be wheeled back, leaving the doffers behind, so that the
cylinder and doffers as well as the condensing parts can be more readily and
conveniently cleaned, examined, and repaired than is the case with the ordinary
fixed condensing frame, thereby greatly reducing the labour and time necessary for
such purposes. I do not confine myself to this method of removing the aforesaid
condensing parts as there are other means of doing so, such as sliding, &c.
And in order that the nature and novelty of my said Invention may be more
readily and properly nnderstood, I have joined hereto a Sheet of Drawings which
represent the various portions of the same, and in which,-
Figure 1 shows the arrangement of the "doffer" cylinders, surface drums, and
incidental parts when working, A being the "doffer" cylinders; B, the new
method of carrying the doffer cylinders by brackets fixed to carding frame; C, the
method of fastening the condensing fraine to the carding frame by means of bolts;
E, the surface drums for carrying bobbins; F, the condensing frame which carries
the whole of the working parts of the condensing machine following the "doffer
cylinders; G, the wheels on which the condensing frame is mounted.
Figure 2 shows a grinding roller and bracket H, which can he readily fixed to
either of the "doffer" cylinders when the condensing frame F is run out, as shown
in this Figure; J are taper pins which fit into the holes K, so as to steady the con-
densing machine when connected, as shown at Figure 1.
The different parts are indicated by the same letters in both Figures.
Having now described the nature of my Invention and the manner in which the
same is to be performed, I wish it to be understood that I do not limit myself
to the precise details herein-before described, as the same may be varied without
departing from the nature of my said Invention; what I claim as my Invention is,
the improvements in the construction of "condenser carding engines,"
Firstly. By the employment of three or more "doffer" cylinders.
.Secondly. By the mechanical arrangement by which the whole of the condensing
machine following the doffer cylinders can be easily removed, substantially as
herein described, and is illustrated on the accompanying Sheet of Drawings, or any
mere variation or modification thereof.
In witness whereof, I, the said James Bragg, have hereunto set my hand
and scal, this First day of September, in the year of our Lord One thousand
aight hundred and seventy-seven.
