Year: 1876

page_text: LETTERS PATENT to Michael Tomkinson and William Adam, both of Kidder-
minster, in the County of Worcester, for the Invention of "AN IMPROVEMENT
IN THE MANUFACTURE OF CARPETS AND RUGS, AND IN
MACHINERY OR
APPARATUS Therefor.
"
Sealed the 29th December 1876, and dated the 29th September 1876.
PROVISIONAL SPECIFICATION left by the said Michael Tomkinson and
William Adam at the Office of the Commissioners of Patents on the
29th September 1876.
MICHAEL TOMKINSON and WILLIAM ADAM, both of Kidderminster, in the County
of Worcester. "AN IMPROVEMENT IN THE MANUFACTURE OF CARPETS AND RUGS,
AND IN MACHINERY OR APPARATUS THEREFOR."
Our Invention has for its object the production of the chenille better closed and
improved in appearance than hitherto, and consists in employing for the same in
the manufacture of the said carpets and rugs a suitable system or arrangement of
cog wheels or other mechanism in connection with the cutting machine used in
cutting the chenille for causing the closing bed and water roll to revolve, and
thereby more effectually damping and closing the chenille, at the same time
allowing a greater strain to be applied to the cloth and better enabling it to
maintain its position in the grooves and on the beds during the process of
manufacture.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Michael Tomkinson and William Adam in the Great Seal Patent
Office on the 22nd March 1877.
MICHAEL TOMKINSON and WILLIAM ADAM, both of Kidderminster, in the County
of Worcester. "AN IMPROVEMENT IN THE MANUFACTURE OF CARPETS AND RUGS,
AND IN MACHINERY OR APPARATUS THEREFOR."
Our Invention has for its object the construction and employment of machinery
or apparatus for facilitating the manufacture of chenille carpets and rugs by a more

page_text: effectual method than hitherto, whereby the chenille is not only greatly improved
in appearance but better closed than by the process at present in use, and consists
in employing for the above an arrangement of cog wheels revolving with the shaft
or other suitable mechanism in connection with chenille cutting machinery for
facilitating the action of the closing bed, and enable the same to revolve more
effectually and advantageously than hitherto for completely closing the chenille and
admitting of a greater strain being given to the cloth, so as to better keep it in
position in the grooves and on the beds during the said manufacture.
And in order that our Invention may be more fully described and readily
carried into effect, we now proceed to describe the same by aid of the accompanying
Drawings, reference being had to the letters and figures thereon marked (that is to
say):
Fig. 1 represents a side elevation of a chenille cutting machine employed by us
in the manufacture of carpets and rugs, showing our improvements in connection
therewith; Fig. 2, a vertical front view thereof, partly in section; and Fig. 3, a
detached view of a modification of our improved gear in lieu of the strap above
described.
In each Figure the same letters of reference denote similar corresponding parts.
A, standard framing or body of the machine; B & B¹, fast and loose pulleys
receiving action from the driving band B2 for communicating direct motion to the
main shaft C of the machine; D, pinion wheel keyed upon the said shaft so as to
revolve with the-same in gear with the intermediate spur wheel E mounted in
suitable bearings F on the frame of the machine aforesaid; G, fixed pulley moving
in union with the spur wheel E for giving motion (through the medium of the
endless band H) to the connecting rigger wheel I working in bearings attached to
the frame; J, pinion wheel revolving with the wheel I in gear with the cog
wheel K on the closing bed; L & L¹, strap and pulley wheels for actuating the
knife cylinder M upon the shaft or axis N, turning in bearings O by means of the
fixed motion pulley P in manner shewn; Q, cutting bed; R, the closing bed
revolving in direct communication with the main shaft through the medium of our
improved system of tooth and pinion gear, as above described; S, continuous belt
for working other parts of the machine, by the whole combined arrangement and
mechanical action of which the closing bed is made to revolve with greater
precision, and thus to more effectually close the chenille than by other systems in
use, and at the same time allow a greater strain to be applied to the cloth so as to
better keep it in its position in the grooves and on the bed.
In conclusion to the foregoing description, we would here briefly note that we are
aware the closing bed in chenille cutting machinery hitherto employed in the
manufacture of carpets and rugs has before received motion from a cross belt on the
main shaft of the machine, we do not therefore claim the revolving closing bed
except in conjunction with the toothed wheel and other intermediate gear employed
by us, as herein-before described.
And we would again note that in lieu of the belt H a cog wheel may also be
employed for connecting the two wheels F & I, represented at Fig. 3, so as to
run together in gear with each other and give the requisite direct motion to the
closing bed in like manner to the belt aforesaid.
And we would again further note that the water roll herein-before provisionally
referred to may be employed conjointly with our said improvements, or otherwise
modified, as in practice may be found necessary.
Having now fully described and ascertained the nature of this our said Invention,
and the manner in which the same is to be performed and carried into effect, we
would have it clearly understood that we do not by any means confine ourselves to
the precise details herein-before set forth and described, as the same may be
otherwise varied or receive such other modifications as in practice may be found
desirable without departing from the general principle of these our said improve-
ments, nor do we claim as new and of our said Invention the exclusive use of the
several parts, combinations, and processes, except when the same are employed in'

page_text: and for the purposes of our said Invention, which we hereby declare to consist in
giving revolving motion to the closing bed in chenille cutting machines direct from
the main shaft through the intervention of cog and strap wheel gear for more
completely closing the chenille and maintaining an increased strain upon the cloth
and set position in the grooves and on the beds, substantially in the manner and for
the purposes herein-before set forth and described.
In witness whereof, we, the said Michael Tomkinson and William Adam, have
hereunto set our hands and seals, this Nineteenth day of March, in the year
of our Lord One thousand eight hundred and seventy-seven.
