IMPROVEMENT IN RING THROSTLES AND DOUBLING FRAMES
Year: 1884

page_text: We THOMAS SMITH, JOHN SMITH and JOHN LEIGH of Stockport in the County of
Chester do hereby declare the nature of the said Invention for AN IMPROVEMENT
IN RING THROSTLES AND DOUBLING FRAMES to be as follows:-
Our Invention has for its object to prevent or lessen the damage to the yarn in
the operation of spinning and doubling in the machinery fitted with ring and
traveller mechanism the said damage arising from broken ends of yarn coming
into contact with the rings and absorbing oil therefrom. To remedy this defect
we employ a thin shell or annular shield which is held in position within the ring.
Between this shield and the ring we leave just sufficient room for the traveller.
When a yarn breaks the end comes into contact with the inner surface of this
shield and as, this surface is free from oil the yarn is not damaged. The shield may
be fixed to the ring rail in any suitable manner. In one arrangement we fix the
shield to a plate which is situated below and is fixed to the ring rail and carries a
number of shields. Any oil dropping from the rings is received and retained by
this plate. The shield may be forined in one piece with the said plate by stamping
or by other means.

We THOMAS SMITH, John Smith and JOHN LEIGH of Stockport in the County
of Chester do hereby declare the nature of the said Invention for "AN IMPROVE-
MENT IN RING THROSTLES AND DOUBLING FRAMES," and in what manner the
same is to be performed to be particularly described and ascertained in and by
the following statement and accompanying drawings :—
Our Invention has for its object to prevent or lessen the damage to the yarn in
the operation of spinning and doubling in the machinery fitted with ring and
traveller mechanism the said damage arising from broken ends of yarn coming into
contact with the rings and absorbing oil therefrom. To remedy this defect we
I Prin

page_text: emlpoy a thin shell or annular shield which is held in position within the ring.
Between this shield and the ring we leave just sufficient room for the traveller.
When a yarn breaks the end comes into contact with the inner surface of this
shield and as this surface is free from oil the yarn is not damaged. The
accompanying drawings illustrate the manner in which we carry our Invention
into effect. In the said drawings Fig: 1. represents a cross section of a ring rail
taken on the centre line of a ring and Fig: 2. is a plan of a portion of the ring rail
showing two rings provided with our protectors. In the said Figs: a is the
ordinary ring rail and b is a ring. Below the rail is a plate c which carries the
aforesaid shields d. d. In Fig: 2. a portion of the rail is left out in order to show
the plate c. and the shields. In practice we make the said plate and the shields of
tin plate or of sheet zinc or of sheet iron or steel but we do not confine ourselves
to the use of any particular material. The shields may be soldered or fixed to the
plate or be formed in one piece therewith by stamping or by other means. The
edges of the plate are turned up so as to embrace the rail and the plate is secured
to the rail by means of clips e. which are hinged by one end to one edge of the
plate c. and extend across the rail cach clip being shaped to pass between two
contiguous rings. In the example only one of these clips appears but it will be
understood that they are hinged to the plate at suitable intervals. The outer end
of each clip is formed with a tubular eye into which a sliding bolt f. can be shot
when the plate is in position the plate being thus secured to the rail. Each shield
is made of a suitable diameter to enter the ring and to leave sufficient space for the
free passage of the traveller. It will be understood that each shield is fixed or
formed on the margin of a circular hole which is formed in the plate c. The said
plate is formed with other openings as at g. to clear the crutch heads on the tops
of the lifting rods and the margins of these openings are raised or turned up so that
any oil which may drop upon the plate is retained. It will be seen that ench
circular shield will prevent the contact of the yarn ends with the ring so that
lubricant may be used more freely when our Invention is adopted. Whenever
desirable the plate can be removed for cleansing by unlocking the clips and turning
them up and backward.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed we declare that what
we claim is :
1. The circular shields d. d. carried by a plate c. extending below the ring rail
the said shields extending upward within the rings substantially as and for the
purpose set forth and indicated.
2. The application to and below the ring rail of an oil catcher formed with
circular shields which extend upward within the rings to keep the yarn ends from
contact with the oiled surfaces of the ring.
