IMPROVEMENTS IN SPINNING AND TWISTING FRAMES
Year: 1879

page_text: LETTERS PATENT to James Barbour, of Belfast, in the County of Antrim,
Ireland (Machinist), for the Invention of "IMPROVEMENTS IN SPINNING AND
TWISTING FRAMES." A communication from abroad by Andrew Coulter, of
Riga, in the Empire of Russia.
Sealed the 25th November 1879, and dated the 28th May 1879.
PROVISIONAL SPECIFICATION left by the said James Barbour at the Office
of the Commissioners of Patents on the 28th May 1879.

"IMPROVEMENTS IN SPINNING AND TWISTING FRAMES." [A communication from
abroad by Andrew Coulter, of Riga, in the Empire of Russia.]
These improvements consist of a novel method of lubricating the collars of the
vertical spindles of spinning, twisting, and similar frames, and also of a peculiar
form of flyer.
The improvement in lubricating spindles is the outcome of the Invention for
which Letters Patent, No. 1708, 22nd April 1876, were granted to the present
applicant, and consists of a boss or projection on the insido of the oil cup and round
the spindle, the top of this projection being about or nearly level with the outer
rim of the oil cup. On the outer surface of this projecting boss are one or more
suitably shaped grooves which conduct the oil to the upper edge of the projecting
boss, and thence to the revolving spindle. These grooves always remain full of
oil; however, the level thereof may vary in the cup; thus a continuous supply of oil
is given to the spindle, and the cups only require replenishing at long intervals. It
is necessary where the oil remains so long in the cups to have them covered. This
arrangement of grooves in the projecting boss in the oil cup supersedes the ":
'ring'
to form the annular space around the projecting boss which was the subject of the
previous Patent.
"
The second part of this Invention consists of a novel form of flyer in which the
legs are bent backwards from the direction in which they turn, so that the yarn in
passing from the thread plate to the eye of the flyer does not touch the leg or
shoulder of the flyer. By this arrangement the yarn is not frayed or rubbed by
contact with the leg or shoulder of the flyer, and so a more even yarn or twist is
produced.

"IMPROVEMENTS IN SPINNING AND TWISTING FRAMES." A communication from
abroad by Andrew Coulter, of Riga, in the Empire of Russia.
These improvements consist of a novel method of lubricating the collars of the
vertical spindles of spinning, twisting, and similar frames, and also of a peculiar form
of flyer. The nature of these improvements will be understood from the following
description, reference being had to the accompanying Drawing, wherein the same
figures and letters of reference always apply to the same or like parts. Figures 1,
2, and 3, are explanatory of the limproved form of flyer, and Figures 4, 5, 6, and 7
illustrate the novel method of lubricating the collars or bearings of the vertical
spindles of spinning and twisting frames.
The improvement relating to lubricating spindles consists of a boss or pro-
jection a on the inside of the oil cup a¹ and round the spindle b, the top of
this projection being about or nearly level with the outer rim a' of the oil cup. On
the outer surface of this projecting boss a are one or more suitably shaped grooves c
which conduct the oil to the upper edge of the boss, and thence to the revolving
spindle b. These grooves c always remain full of oil; however, the level thereof may
vary in the cup a¹; thus a continuous supply of oil is given to the spindle b, and the
cup a¹ only requires replenishing at long intervals. It is necessary where the oil
remains long in the cup to have it covered as shown in the section d, Fig. 5.
The projecting boss a may be either parallel on its outer surface with the axis
of the spindle, as in Figures 4 and 5, or conical as in Figures 6 and 7.
The second part of this Invention consists of a novel form of flyer, in which the
legs e are bent backwards from the direction in which they turn, as shewn in
Figures 1, 2, and 3, so that the yarn ƒ in passing from the thread plate f¹ to the
eye e of the flyer e does not touch the leg or shoulder of the flyer e.
By this arrangement the yarn is not frayed or rubbed by coming in contact with
the leg or shoulder of the flyer, and thus the production of an even yarn or twist is
ensured.
Having now set forth the nature of the Invention of "Improvements in Spin-
ning and Twisting Frames," as communicated to me from abroad, and explained
the manner of carrying the same into effect, I wish it to be understood that under
the above in part recited Letters Patent I claim,―
Firstly. The use of a projecting boss around the spindle with a groove or grooves
on its outer surface for conducting the oil to the vertical spindles of spinning and
twisting frames.
Secondly. The peculiar form of flyer with legs bent backwards from the
direction in which they turn, substantially as and for the purpose above described.
In witness whereof, I, the said James Barbour, have hereunto set my hand
and seal, the Twenty-first day of November, in the year of our Lord One
thousand eight hundred and seventy nine.
