Improvements in Apparatus for Measuring and Recording or
Indicating the Length of Yarn, Thread, or Strands Twisted or
whilst being, Twisted.
I ABRAM COMBE of Falls Foundry Belfast, Ireland, Machinist do hereby
declare the nature of this invention to be as follows:-
The object of this invention is by improved apparatus to record the length of
twisted yarn, thread, or strand, that passes on to the bobbin, after being twisted
in differential twisting frames, or strand forming machines, that is to say, in twisting
frames, in which the yarns or threads, that are being twisted, together, are drawn
from the creel through a forming tube, or eye, by means of hauling pullies, carried
by the flyer, which hauling pullies, are caused to revolve on their axes, by being
geared with a central pinion driven at a different speed from the flyer itself, this
difference in speed, imparting the rotary motion to the hauling pullies, and the
or "strand"
variations in this difference of speed determines the length of "twist
pulled through the forming tube or eye for a given number of revolutions of the
flyer.
"
The object of this my said invention is accomplished by applying to, and com-
bining with, stranding, twisting or doubling mechanism, such as described in
Specification No. 4112, 1891 filed by the present applicant, an arrangement of
"Jack" or differential motion, consisting of three or four bevel wheels, one of
these bevels is driven from the flyer, and the speed at which it revolves, bears &
fixed proportion to the speed of the flyer. Another bevel is driven in the opposite
direction, from the central pinion, that drives the haul pullies, and the speed at
which it revolves, bears the same proportion to the speed of the central pinion, as
the above mentioned bevel, bears to the speed of the flyer.
Both these two bevels gear into one or two bevels, carried by a wheel or pulley,
or on a radial stud, or studs, on a shaft, this wheel pulley or shaft being caused
to revolve by the difference in the speeds of the first mentioned bevels and at a
speed corresponding to this difference.
By employing the wheel pulley or the shaft, which carries the last named bevel,
or bevels, to drive a worm, worm wheel and cross shaft, an indicating dial and
pointer or a bell motion are or is operated and the length of twisted yarn thread
or strand, pulled through the forming tube or eye, is recorded or indicated.

5 Improvements in Apparatus for Measuring and Recording or
Indicating the Length of Yarn, Thread, or Strands Twisted or
whilst being Twisted.
I, ABRAM COMBE, of Falls Foundry, Belfast, Ireland Machinist, do hereby
declare the nature of this invention and in what manner the same is to be
O performed, to be particularly described and ascertained in and by the following
statement:
The object of this invention is by improved apparatus to record the length of
twisted yarn, thread or strand that passes on to the bobbin, after being twisted in

differential twisting frames or strand forming machines, that is to say, in twisting

ground with a central pinion driven at a different speed from the flyer itself, this

variations in this difference of speed determines the length of twist or

The object of this my said invention is accomplished by applying to and com-
bining with stranding, twisting or doubling mechanism, such as described in
Specification No. 4112, 1891 filed by the present applicant, an arrangement of
jack" or differential motion consisting of three or four bevel wheels one of these
bevels is driven from the flyer, and the speed at which it revolves bears a fixed
proportion to the speed of the flyer. Another bevel is driven in the opposite
direction, from the central pinion, that drives the haul pulleys and the speed at
which it revolves bears the same proportion to the speed of the central pinion as
the above mentioned bevel bears to the speed of the flyer.
Both these two bevels gear into one or two bevels, carried by a wheel or pulley,
or on a radial stud, or studs on a shaft, this wheel pulley or shaft being caused to
revolve by the difference in the speeds of the first mentioned bevels and at a speed
corresponding to this difference.
By employing the wheel pulley or the shaft, which carries the last named bevel
. or bevels, to drive a worm, worm wheel and cross shaft, an indicating dial and
pointer or a bell motion are or is operated and the length of twisted yarn thread
or strand pulled through the forming tube or eye is recorded or indicated.
'
Such being the nature and object of my said invention the following is a complete
description of same reference being had to the accompanying drawings forming
part of this Specification in which :-
Fig. 1. is a sectional elevation of a measuring apparatus embodying the features
of my invention.
Fig. 2. is a plan view of said measuring apparatus.
Similar letters of reference designate corresponding parts in both figures.
The shaft 1 of the twisting frame drives the flyers of said frame at a constant
speed, and the speed of shaft 1 bears a certain ratio to the speed of the flyers.
The shaft 9 drives the central wheel which drives the hauling pulleys and are
being carried in the flyers the ratio of speed between the shaft 9 and the central
pinion being the same as between the shaft 1 and the flyers, and as the hauling
pulleys are geared with the central pinion the difference in the speed of shaft
and shaft 9 is in direct proportion to the length of yarn, twist or thread pulled
through by the hauling pulleys. To register the difference in speed between
shaft 1 and shaft 9 and thereby the length of twist pulled through by the haul
pulleys.
Worms A. and A¹ are placed on the shafts 1 and 9 respectively; the worm A
gearing into a worm wheel B, and the worm A' into a worm wheel B¹ these worm
wheels being so arranged that the wheel B turns in the opposite direction from
wheel B¹.
On the worm wheel B is mounted a bevel D and on the worm wheel B' is
mounted a bevel C, and both these bevels gear into one or two bevels G and H
which are carried by a wheel or pulley or by a radial stud or studs F fixed on a
shaft E, this wheel, pulley or shaft being caused to revolve by the difference in
the speeds of the bevels C and D and at a speed corresponding to this difference.
The number of revolutions of shaft E can be registered by an ordinary dial or
counter motion, such as shewn in Figs. 1 and 2 viz::-A worm L is mounted on.
shaft E and works into a worm wheel M placed on a cross shaft N then an
ordinary indicating dial O or a pointer P or a bell motion is used and registers the
speed of shaft E and in turn the difference in speed between the shafts 1 and 9

page_text: and consequently the length of twisted yarn, thread or strands pulled through
the forming tube or eye.
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 :-
The improved apparatus herein described and illustrated whereby the difference
in speed of the central pinion which drives the hauling pulleys and the speed of
the flyers (in differential, doubling, twisting or strand forming machines) operates
an indicating pointer or indicating dial, or by bell motion and pointer, which
registers the length of twisted yarns, thread or strands that are pulled through the
forming tube or eye of such machines.
