COMPLETE SPECIFICATION.
Improved Thread-doubling Machine.
I, JOHN PITT BAYLY, of 18, Fulham Place, Paddington, in the County of
London, Patent Agent, do hereby declare the nature of this invention (a com-
munication to me from abroad by N. S. Perkins, of New London, Connecticut,
U.S.A., Gentleman,) to be as follows:-
My invention relates to improvements in thread-doubling machines; and the
objects of my invention are to improve the efficiency of the machines, to produce
a machine specially adapted for uniting three strands, and to combine with the
movable guide a stop motion.
In the accompanying drawings
Fig. 1 is a front elevation of so much of a thread-doubling and winding-device as
is necessary to show my improvement.
Fig. 2 is a side elevation thereof on the same showing some of the parts in vertical
section.
Fig. 3 is a plan view of my thread-guides.
Fig. 4 is a plan view of the lower thread-guide.
Fig. 5 is a front elevation of one of the spools and its driving-mechanism as
operated upon by the stop-mechanism.
Fig. 6 shows, partly in elevation, a larger sectional view on line cc of Fig. 4 of
the supports for the movable thread-guide, and
Fig. 7 is a detached view showing a modification.
A designates a driving-shaft bearing friction driving-pulleys B B, upon which

page_text: the sides of the spool C rest, and by which they are driven, and D designates
the driving-bar over which the united strands are guided when being wound
upon the receiving spool C, all as any ordinary thread winding machine, and for
which any known driving mechanism and receiving-spools may be substituted.
I consider it unnecessary to show the entire frame of the machine, as any frame
which will support the parts in the respective positions shown, will answer all
the requirements of my invention.
7, 8, and 9 designate longitudinal bars of the frame, upon the lower one of which
the several delivery spools or bobbins 10, containing the threads to be united,
are arranged for unwinding in any ordinary manner.
Upon the bar 8 of the frame I secure the tension regulating device of my
winder.
11 designates a bracket bearing at its upper and lower ends the plates 12 and 13,
having notches 14 formed in their edges, which notches serve as upper and lower
fixed guides for the several strands to be united.
Upon the lower plate 13 I arrange a rod 15 which is connected to said lower
plate 13 by a ball-and-socket joint 16, whereby said rod can move as on a universal
joint. The upper end of this rod 15 bears the movable thread-guides 17, which
should be arranged about mid-way between the upper and lower fixed thread-guides,
as shown. I have illustrated three of these niovable guides and three strands of
thread 18 as being united. These strands run from the delivery bobbins or spools 10
through the lower fixed guides 14, then inwardly and upwardly to and through the
movable guides 17 then outwardly and upwardly to and through the upper fixed
guides in the plate 12, and then upwardly to the uniting point on the guide bar D in
front of the receiving-spool C. When thus being united, if one of the strands is
strained more or less than others the movable guide immediately moves by reason
of its universal joint into a position to equalize the varying tension of the strand,
all substantially in the manner shown and described in reissued U.S.A. Letters
Patent, No. 10364, to Albert Washburn, dated August 7th, 1883, but differing
therefrom in the arrangement of the movable guide upon a roà having a universal
joint.
While I have shown this doubler as uniting three strands it may be used for
uniting two strands, by merely dropping one strand and passing the remaining two
in one of the notches 19 of the upper and lower fixed guides, and in like manner
any number of strands may be united by providing a suitable number of notches for
the upper and lower fixed guides, and a corresponding number and position of the
movable guides at the upper end of the rod 15. Thus if the machine is constructed
specially for uniting only two strands, then there need be only two notches in the
upper and lower fixed guides, and only, two movable guides on the upper end
of the rod.
While greater usefulness is attained when my machine is used for uniting three
strands than when only two are united, it is of an apparent advantage to have a
machine that may readily be changed for use in uniting two or three or other
number of strands when desired, and so far as I know, no such machine has ever
before been produced or patented, or described in any printed publication. In order
to accomplish the best results the moving thread-guides should have the greatest
possible freedom of movement, and this they have at all times in any machine
where two or more strands are being united. I also extend the rod 15 some
distance below the universal joint 16 and immediately underneath it I arrange
a circular step 20 upon the upper side and outer end of the stop-actuating lever 21,
said step being centrally located with reference to the axis of the rod 15 when said
rod is in vertical position. This lever 21 is weighted as at 25, and provided with
an upwardly projecting arm 22 which bears upon the lower end or arm of the stop
lever 23, as shown in Fig. 2. The contacting ends of the arm 22 and lever 23 are
also illustrated by broken lines in Fig. 1. The upper end of the stop lever 23
carries a swinging arm 24 that rests upon the periphery of one of the driving
wheels B immediately under one of the heads of the spool C, as shown in Fig. 2.

page_text: In the ordinary operation of the machine the varying tensions of the several
strands will not move the rod 15 sufficiently out of an upright position to throw its
lower end off the face of the circular step 20, but in case any of the strands
should break, the remaining strands will pull the movable thread guides so far
to one side that the lower end of the rod 15 will slip off the circular step 20,
and thereby leave the stop actuating lever 21 free to be acted upon by its
weight 25, and through the arm 22 and lever 23 to operate the stop-mechanism
by pushing the swinging-arm 24 under one of the heads of the spool C, as
indicated by broken lines in Fig. 2, and thereby lift one end of the spool into
the position shown in Fig. 5. In this position there will not be friction enough
upon the other head of the spool to drive it, and, consequently, it is immediately
stopped by the stop-mechanism so soon as one of the strands is broken.
While I have illustrated a particular kind of stop mechanism it is one that is
well known, and other stop-mechanisms may be substituted therefor, the essential
feature of my combination consisting of the lower end of the rod that supports
the movable thread guides, the circular step of the stop-actuating lever 21,
whereby the lower end of said rod upon the breaking of a thread immediately moves
to one side and permits the stop-mechanism to act.
In Fig. 7 I have shown a slight modification of the circular step 20 at the lower
end of the rod 15 consisting of securing said step to the lower end of said rod, and
provide an upward projection 26 on the top of the stop-actuating lever 21 ; but the
operation is the same as that already described, only the step slips off the projecting
end 26 instead of having the projecting end of the rod slip off the step, the result
being the same in both cases.
My invention resides chiefly in mounting the movable thread-guides on the rod
which vibrates upon a joint, and in combining therewith the step actuating lever,
and therefore the other parts are shown and described for the purpose of showing
the connection of my invention therewith, and they may be changed, so long as
these essential parts of my invention are retained.
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 :-
1. In a machine for uniting threads, the combination of the upper and lower
thread guides and intermediate movable guides supported on a rod having a
universal joint, and adapted for operating upon two or more threads, substantially
as described, and for the purpose specified.
2. The combination of the upper and lower thread-guides, the rod 15, vibrating
on a universal joint, and provided with movable thread-guides on one end, while its
opposite end projects beyond the joint, the circular step, the stop-actuating lever,
substantially as described, and for the purpose specified.
3. The combination of the upper and lower thread-guides, a rod vibrating on
a joint and having movable thread-guides at one end, and a projecting end on
the opposite side of said joint, the step, and the stop-actuating lever, substantially
as described, and for the purpose specified.
4. In a machine for uniting threads, the combination of upper and lower thread-
guides, a support for movable thread-guides intermediate between said upper and
lower guides, a vertical rod having in connection with said support a universal joint
by which it is mounted, and movable thread-guides mounted on said rod on a plane
above said joint, substantially as described, and for the purpose specified.
