Improvements in the Method of and in Means and Appliances for
Tarring, Colouring, and otherwise Preparing Thread, Hemp, Jute,
or other Twine for Sewing, and in Feeding or Supplying the same
to Sewing Machines.
I, WILLIAM PETERS, of 44 Tenter Street South, Goodman's Fields,
London E., Manufacturer do hereby declare the nature of my said invention
to be as follows:-
The object of my invention is to effect improvements in the method of tarring or
colouring and otherwise preparing thread, hemp, jute, or other twine, for sewing
sacks or other articles by means of sewing machines, and in feeding or supplying
such sewing materials to sewing machines.
In carrying out my invention I use an apparatus consisting of an outer and an
inner vessel, the outer vessel containing water, and the inner vessel containing tar,
colouring matter or other materials. The outer vessel, containing water, is heated
by means of an atmospheric gas burner, or other source of heat, whereby the
contents of the inner vessel are kept at or near the boiling point of the water, by
which it is heated.
The outer cistern is fitted with, or combined with a suitable frame, having
bearings in which two rollers, covered with vulcanised rubber, or other material,
are fitted.
The spindles of these rollers are fitted with toothed wheels, suitably
connected with the main shaft of the sewing machine, in such a manner that the
motion of both shaft and rollers is simultaneous. A perforated bar is also fitted to
the frame, in such a position that any tar or other material intercepted thereby
may fall back into the inner vessel underneath the same, and the twine may be
thereby suitably guided to the rollers. The frame is fitted with one or more spring
or springs above the rollers, the pressure from which may be applied to or
removed from the rollers, by means of a screw, eccentric, or other well known
appliance.
The thread, hemp, jute or other twine (all hereinafter included in the word
"thread") passes from the ball, reel, or other source of supply, into the inner
vessel, containing the tar or colouring matter, under a horizontal pin or bar fitted
near the bottom of the same vessel. The thread is then carried upwards to, and
passes through one of the holes in the above mentioned bar, whereby it is suitably
guided to the rollers. The thread then passes between the rollers, whereby all
surplus material is removed from the thread, which then passes direct to the
sewing machine. The speed of the rollers is at all times regulated so as to feed
the tarred or colored thread, at the required speed, direct to the needle of the
sewing machine.

Improvements in the Method of and in Means and Appliances for
Tarring, Colouring, and otherwise Preparing Thread, Hemp, Jute,
or other Twine for Sewing, and in Feeding or Supplying the same
to Sewing-machines.
I WILLIAM PETERS of 44 Tenter Street South, Goodman's Fields,
London E., Manufacturer, do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
The object of this invention is to effect improvements in the method of tarring,
coloring and otherwise preparing or impregnating thread, hemp, jute or other twine
for sewing sacks or other articles by means of sewing-machines and in feeding or
supplying such sewing materials to sewing-machines.
In carrying out my invention I employ means and appliances such as are
illustrated in the drawings annexed hereto, wherein
Fig. 1 is a side view of construction according to this invention applied to the
table of the sewing-machine to which the impregnated twine is to be supplied.
Fig. 2, is a face view of the same seen from right hand side of Fig. 1.
Portions of the vessels are broken away for facility of illustration.
A, indicates the framing and table of the sewing-machine to which the device is
applied and B, is the sewing-machine "motion-shaft," carrying a cone pulley C,
which drives, by strap, the cone D, of the gearing of the feed rollers of the
appliance which I will now proceed to describe.
a, is an outer vessel and 6, is an inner vessel, said outer vessel containing water
and the inner vessel containing the tar, coloring matter or other impregnating
material wherewith the twine or thread supplied is treated. This outer vessel a, as
shown in the drawings is of cast iron and carries the frames c, of a piece therewith
all being bolted down to the table A.
Under the outer vessel a, is provided a space for a gas burner d, or other source
of heat and the bottom edge of vessel a, is formed with a lip a¹, so that if any of
the contents of the vessels comes over it will fall clear of the flame.
The inner vessel b, stands in the outer vessel a, upon feet b', so that the space
between these two vessels acts as a water-casing to the inner vessel b, and the
contents thereof can be maintained at required degree of heat.
The twine or thread a, from the ball, or source of supply, is carried into the
inner vessel b, under a bar 62, which is secured to one side of the vessel b, and
extends partially across within the vessel. This will allow. of the twine being
passed by a fork or pair of jaws conveniently over the end of and under the said
bar 2. The free end of the twine or thread will then be passed through one of a
series of holes in a cross bar e, acting as guide and as a cleaner or scraper to the
twine as it comes up out of the contents of the vessel b, whence said twine is passed
between rollers f, g, and further cleansed, by expression, at the same time that it is
drawn forward and delivered out to the proper
"
" tensions or guides and to the
needle of the sewing machine.
The axles of the rollers f, g, are carried in the movable bearing blocks f¹, g', the
upper blocks f', whereof are acted upon by the spring h, the pressure of which is
regulated by the cam ¹ and adjustable nut h².
The rollers are covered with vulcanized rubber or other material so as to afford
a good but yielding grip on the thread. The upper roller f, is geared and driven
by spur wheels 2, 92, from the axle of the lower roller g, to which motion is given
through suitable connections from the "motion-shaft" B, so that the delivery of the
twine or thread will be simultaneous with and equal to the quantity required for
the stitching done by the sewing-machine.
In as much as the machine so fitted will be required to be used from time to
time for different thickness of twine or thread and of material to be operated

page_text: upon and varying size of stitch the cone strap will be required to be set
accordingly and for this purpose there is provided the guide fork i, which will
be set as and when required by a set screw, not shown which holds and secures
the said fork to the framing.
The simultaneous motion of the rollers f, g, in relation to the sewing-machine
will conveniently be effected by gearing such as is shown, that is to say, the
axle of the roller g, carries the spur wheel g³, which engages with carrier pinion k,
the latter gearing with spur wheel l, on face of which is a bevil m, gearing with
bevil n,
fixed to pinion o, engaging with spur wheel p, (by carrier pinion o').
Upon the shaft of the spur wheel p, is carried one of the pair of bevil wheels
the other one of the pair being mounted upon the shaft of the cone D, thus com-
pleting the requisite train for the simultaneous motion between the sewing-machine
and the feeding device.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
First. Supplying thread to sewing-machines direct from the tarring, coloring or
preparing tank, such tank being water-jacketed and heated substantially as and for
the purpose set forth.
Secondly. In means for supplying twine or thread to sewing-machines the feed
rollers f, g, operating to furnish the prepared thread to the needle in quantity as
requisite for the stitching as the same proceeds, as herein specified.
Thirdly. The preparing and supplying appliance for twine or thread for sewing-
machines constructed and operating as and for the purpose substantially as herein
set forth and shown by the drawings.
