"IM-
This Invention relates to a novel arrangement of the "workers" upon the surface
of the "swifts" of scribbling and carding engines, and consists in arranging such
workers close together or nearly so, instead of leaving a considerable space between
them as hitherto. By this arrangement I am not only enabled to increase the
number of "workers employed, but each worker acts as a cleaner upon those
adjacent to it, so that it is not necessary to remove the workers to be cleaned, an
operation which is of frequent occurrence when "workers" are arranged on the old
system, and which causes a great waste of time and labour, I also employ cards
formed from a continuous strip or strips of serrated metal wound round the
cylinders, instead of the usual wire cards for the above purpose.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Joseph Hemingway in the Great Seal Patent Office on the 20th March

"
This Invention relates to a novel arrangement of the workers and "strippers
upon the surface of the swift or breast of scribbling and carding engines em-
ployed in the preparation of wool and other fibrous substances, and consists in
arranging such "workers" and "strippers" closer together than hitherto, whereby we

page_text: are enabled to increase the number thereof. I also employ cards formed from a
continuous strip or strips of serrated metal wound round the cylinders instead of the
usual wire cards.
The cylinders for both swift workers and strippers are constructed of metal,
having a continuous groove or thread turned in the periphery or surface, and the
serrated metal card is pressed into the groove whilst being wound on the cylinder,
so that if it breaks when working the ends do not fly loose, but remain fast on the
cylinder.
By my improvements, which I prefer to apply to the first swift or breast of the
machine, a great saving of time and labour is effected, as it is not necessary to
remove the "workers" and "strippers' for the purpose of cleaning them as
frequently as when ordinary cards are used.
"
I may also add my improvements to any of the remaining swifts as well as to
the first swift or breast.
The accompanying Sheet of Drawings illustrates my Invention sufficiently to
enable persons practically acquainted with carding machinery to understand and
carry out the same. It represents a sectional elevation of an ordinary "scribbler"
carding engine, of which the first "swift" or "breast" A is covered with card of
the form shewn in detail, Fig. 2, and fully described above. The "workers" and
" strippers B it will be seen are much closer than usual, the first four being
arranged so as to nearly touch each other, and the remainder having rather more
space between. These "workers" and "strippers" are also clothed with the same kind
of card as the swift. Between the first and second swift I place only the angle
stripper D, dispensing with the "fancy" and "doffer."
"
Having thus described the nature of my Invention, and the manner in which the
same is to be performed and carried into practice, I would have it understood that
I do not confine myself to the precise arrangement herein shewn, neither do I claim
the peculiar kind of card herein described, but what I claim as my Invention, and
consider to be new is, the employment of the metal "swift
or "breast" A, and
"workers" and strippers thereon clothed with serrated metal as herein described,
in combination or coupled along with the other "swifts" and "workers" clothed and
arranged in the ordinary manner.
"
In witness whereof, I, the said Joseph Hemingway, have hereunto set my
hand and seal, this Nineteenth day of March, in the year of our Lord One
thousand eight hundred and seventy-seven.
JOSEPH HEMINGWAY. (L.S.)
