page_text: Improvements in Spinning-rings and Travellers.
I, HORACE LORING HAYDEN of Plymouth, in the County of Plymouth, State of
Massachusetts, United States of America, mechanic, do hereby declare the nature
of my invention for IMPROVEMENTS IN SPINNING RINGS AND TRAVELLERS, and in
what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :-
My invention is an improvement in travellers and traveller-rings for twisting
frames. The object of my invention is first, to render the friction of the yarn
upon the traveller variable at pleasure, within certain limits whereby the twisted
yarn may be wound more or less tightly upon the spool or bobbin.
Further my object is to render the friction of the traveller variable in the race,
whereby the amount of twist may be varied. I have also sought to improve the
construction of the ring and traveller in particulars hereinafter pointed out.
In the accompanying drawings Fig. 1 is a plan view of the ring and Fig. 2. is a
side elevation. Fig. 3 is a section. Fig. 4 is a view of the traveller detached.
The ring is composed of two parts, an outer A and inner B. As shown, the
inner part is a solid ring formed with an extension a to enter the rail, and a
flange b to rest upon the top of the rail. The part c extending above the rail is
formed with a shallow groove, with a low armed pit above it, showing
approximately an ogee curve.
The outer flange ring has a bottom f, adapted to rest upon the rail outside of
the inner ring flange b. The bottom of the ring has a rebate g to fit over flange b.
The inner face of this outer ring is grooved as shown at 2, Fig. 3 and the upper
edge is slightly rounded.
This ring is cut, as shown at 3, and has lugs 4, 4; and each lug is adapted to
receive a screw 5, by means of which the diameter of the ring may be increased or
diminished.
The two rings when put together, as shown in Fig. 1, leave an annular race
between them, larger in its lower part and adapted to receive and retain a traveller
of suitable shape.
The outer ring is held to the rail by screws in the slots
inclined to allow the ring to move in contracting or expanding.
6, these slots being
The improved traveller is shown at E. As ordinarily made these travellers
are simple hooks or clasps of brass, placed over and partially embracing the ring

page_text: or flanges thereon. The friction of the yarn upon these travellers, as well as their
friction on the ring is invariable, and after a little use the traveller becomes so
worn and grooved that it necessarily cuts the thread and breaks the end down.
To provide for the variation of the friction upon the yarn, I have made the
traveller in the form of a solid block and have set in the upper edge thereof a series
of hooks over one or more of which the yarn may be passed, according to the
amount of friction required.
I prefer to make the block or body of the traveller of brass, babbitt metal or
similar material and to make the hooks of hardened steel. The soft metal of the
body does not wear the rings so rapidly and the steel hooks better resist the wear of
the yarn.
It will be apparent that the expansion or contraction of the outer ring
may be made to increase or diminish the friction upon the traveller.
When the ring is expanded over the shoulders or upper margins of the ribs 7 7,
the traveller will bear on the ring, but when the outer ring is contracted it may.
cause the curved portion of the rings to bear on the whole surface of the sides of
the traveller. The shape of the traveller is adapted to the faces of the rings for
this purpose. In operating this device the yarn is brought down in as many plies
as may be desired and passed under the hook or hooks (increasing the number to
increase the friction) and thence the yarn passes directly to the spool in the
ordinary manner.
In order to cause the traveller to lag and thus to diminish the twist, I have only
to turn up the screw and contract the outer ring.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare what
I claim is
1st An improved traveller ring consisting of an outer and inner ring forming
when together, an annular race enlarged at the bottom in combination with a
suitable traveller, all substantially as described.
2nd In a traveller ring the combination of the inner and outer runs in the
annular race formed by the rings constituting this traveller as an entirety,
substantially as and for purposes herein set forth.
3rd In combination with a traveller ring having an annular race, a traveller
adapted to said race and provided with a series of hooks, all substantially as
described.
4th In combination with a traveller ring having an annular race as described,
a traveller consisting of a body of soft metal and having hardened steel hooks as
set forth.
5th The combination with a traveller of the traveller ring, arranged as described,
whereby the size of the annular race may be varied, as and for purposes herein set
forth.
Dated this 11th day of August A.D. 1885.
