IMPROVEMENTS IN MACHINERY FOR THE MANUFACTURE OF OIL CLOTH FOR PACKING PURPOSES
Year: 1884

page_text: PROVISIONAL SPECIFICATION.
I JOHN BLACKWELL of the firm of Messieurs John Blackwell and Company of.
Collyhurst in the city of Manchester, Oil cloth and Tarpaulin manufacturers,
do hereby declare the nature of this my invention for IMPROVEMENTS IN
MACHINERY FOR THE MANUFACTURE OF OIL CLOTH FOR PACKING PURPOSES,
to be as follows:-
.My invention has for its object the construction of an improved Machine for
drawing the cloth through the Oil trough in the manufacture of oil cloth for
packing purposes.
In carrying out my invention I employ a series of two, three, or more, preferably
four swifts mounted on axes in a frame and geared together, such swifts being
driven by means of a counter shaft with fast and loose pulleys. I prefer to con-
struct the outer surface of the swifts of a number of angle irons with the edge of
the angle iron outwards and I so time the swifts with regard to each other that the
angle irons " gear" into each other.
By passing the cloth under and over the swifts, I am enabled to draw such cloth
through the oil trough by power instead of by hand as heretofore and I also obtain
more uniform treatment of the oil cloth. The swifts are mounted upon a suitable
frame which in turn is mounted on wheels running on rails conveniently disposed
near the stove for drying the oil cloth after treatment.
It will be readily understood that this machine may be used for withdrawing the
oil cloth from the drying stove previous to re-treating or finally rolling.

I JOHN BLACKWELL of the firm of Messrs John Blackwell & Company of
Collyhurst in the City of Manchester Oil cloth and Tarpauling Manufacturer
do hereby declare the nature of my Invention for IMPROVEMENTS IN MACHINERY
FOR THE MANUFACTURE OF OIL CLOTH FOR PACKING PURPOSES and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :—
My Invention has for its object the construction of an improved machine for
drawing the cloth through the oil-trough in the manufacture of oil cloth for
packing purposes.
In carrying out my Invention I employ a series of two, three, or more preferably
four swifts mounted on axes in a frame and geared together, such swifts being
driven by means of a counter shaft with fast and loose pulleys I prefer to con-
struct the outer surface of the swifts of angle irons with the edge of the angle iron
outwards and I so time the swifts with regard to each other that the angle-iron
"gear" into each other.
By passing the cloth under and over the swifts I am enabled to draw such cloth
through the oil trough by power instead of by hand as heretofore and I also obtain
more uniform treatment of the oil cloth-The swifts are mounted upon a suitable
frame which in turn is mounted on wheels running on rails conveniently disposed
near the stove for drying the oilcloth after treatment.
It will be readily understood that this machine may be used for withdrawing the
oilcloth from the drying stove previous to re-treating or finally rolling.
And in order that this my said Invention may be better understood and more
readily carried into effect I have hereunto annexed a sheet of drawings and will
now describe my Invention referring to the Figures and letters of reference marked
thereon.
Fig. 1. is a sectional elevation of the machine embodying my improvements and
Fig. 2 is an end view of the same-shewn broken in the centre for want of space to
illustrate it in its entirety.
In both the views A A A are the swifts mounted in the bearings B in the main
frame E preferably mounted on wheels or rollers F running on rails G on the floor
transversely to the direction in which the cloth is carried through the machine and
conveniently near the stove for drying the oilcloth after treatment.
The swifts A A A are geared together by the spur wheels H (of which the pitch
line only is shewn in the drawing) and driven preferably by power by the pinion I
on the shaft J carrying fast and loose pulleys K for the purpose.
The swifts are formed with a series of angle-irons L having the edge of the
angle-irons outwards as illustrated I so time the swifts with regard to each other
that the angle irons L "gear" into each other as illustrated in Fig. 1.
The cloth being treated is passed under and over these swifts A in the direction
of the arrows after it comes from the oil-trough (which is of the ordinary and well
known construction) and when such swifts are set in motion as described it will be

page_text: obvious that the cloth will be steadily and uniformly drawn through the oil-trough
and paid out to the drying stove and I thus obtain a more uniform treatment of the
cloth than has been possible heretofore.
It will be readily understood that the machine may be used for withdrawing the
oilcloth from the drying-stove previous to the re-treating or finally rolling.
.
Having now particularly described and ascertained the nature of my said
Invention and in what manner in which I propose to carry it into effect I wish it
to be understood that I do not confine myself to the precise details thereof nor to
the number of the swifts or angle irons, so that sufficient are employed to effectually
grip" the cloth and draw it through the machine as described and I declare that
what I claim is
"
1st The improved mechanism for the manufacture of oilcloth for packing purposes
substantially as described and illustrated on the accompanying drawings.
2nd The improved combination and arrangement of swifts constructed of angle
iron and geared together substantially as and for the purpose hereinbefore described
and illustrated in the accompanying drawing.
