PROVISIONAL SPECIFICATION left by the said Ferdinand Henry Ziffer at
the Office of the Commissioners of Patents on the 11th March 1878.
FERDINAND HENRY ZIFFER, of Manchester, in the County of Lancaster. "LM-
PROVEMENTS IN THE CONSTRUCION OF THROSTLES USED FOR SPINNING COTTON OR
OTHER FIBROUS SUBSTANCES."
This Invention relates to the construction of that class of throstles known as
"ring throstles," and relates inore particularly to an arrangement for adjusting
with the greatest accuracy the absolute perpendicular position of the spindle, so as
to avoid vibration during its rapid revolution. This I propose to effect by a
peculiar construction and arrangement of the collar or bolster which supports the
spindle in the bolster rail, which I form with a rectangular block above the rail,
and a nut beneath fitting on a screw thread cut upon the lower cylindrical part of
the collar, the hole through the rail being rather larger than the collar; the latter
when adjusted is fixed tight by means of the nut.
The block is made hollow at the top so as to form an oil cup, a hole or passage
being drilled through into the centre to admit the oil to the spindle.
The block can be set either forwards or backwards by means of small set screws
tapped through the front and back flanges of the bolster rail, and having their ends
pressing against the front and back of the block, which is fixed to or forms part of
the collar; thus it will be seen that the spindle can be adjusted in any direction
with the greatest accuracy, and when adjusted can be fixed by screwing up the-nut
underneath. This same method of adjustment may also be adapted to the footstep
rail.

page_text: Another part of the Invention consists in fitting on to the spindle a conical_cup
fitting on to the upper part of the collar, and in boring out the lower part of the
spool to fit on to such cup. The cup fits tight on to the spindle, but can be
removed when it is required to withdraw the spindle.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Ferdinand Henry Ziffer in the Great Seal Patent Office on the 11th
September 1878.
FERDINAND HENRY ZIFFER, of Manchester, in the County of Lancaster. "IM-
PROVEMENTS IN THE CONSTRUCTION OF THROSTLES USED FOR SPINNING COTTON OR
OTHER FIBROUS MATERIALS."
This Invention relates to the construction of that class of throstles known as
"ring throstles," and relates,-
First. To an arrangement for adjusting with the greatest accuracy the absolute
perpendicular position of the spindle, so as to avoid vibration during its rapid
revolution, and also its exact central position in the ring.
And, Secondly. The Invention relates to a means of compensating for any wear
which may occur in the bush at the top of the bobbin, so that notwithstanding such
wear the bobbin will always fit tight on the spindle.
Such being the nature and object of my said Invention, I will now proceed to
describe in detail the manner in which the same is to be or may be performed or
carried into practical effect, and in order that the same may be clearly understood I
have annexed hereunto a Sheet of Drawings illustrative thereof, and have marked
the same with figures and letters of reference corresponding with those in the
following explanation thereof.
Fig. 1 in the annexed Drawing is a section, and Fig. 2 an elevation of a spindle
bobbin, bolster rail and bolster, spindle rail and footstep, constructed and arranged
according to my Invention; Fig. 3 is a transverse section, and Fig. 4 a plan view
of the bolster rail and bolster; and Figs. 5 and 6 are similar views of the spindle
rail and footstep.
a, a, is the bobbin or spool, and b, b, is the spindle; d, d, is the bolster; g, g, the
bolster rail; d, d', the footstep; and g', g', the spindle rail. The bolster d, d, and
the footstep d', d', are each cast with a rectangular block d", d", above the rail, a
screw thread being cut or formed upon the lower cylindrical part of the bolster and
the footstep, and a nut l,, screwed thereon below the rail to fix the bolster or
footstep when adjusted, the hole through the rail being rather larger than the said
cylindrical part to allow of its being adjusted in any direction before being fixed
by the nut, . The adjustment of the bolster and footstep is made by means of
set screws n, n', tapped through the front and back flanges of the bolster and
spindle rails g, g', and having their ends bearing against the block d", d".
It will hence be evident that should the spindle b, b, through working lose its

page_text: exact perpendicular position or become out of the centre of the ring the bolster
and footstep can be adjusted with the greatest accuracy by means of the set
screws n, n².
The blocks d and d' are made hollow at the top so as to form oil caps, a hole or
passage o, o¹, being drilled through the former into the centre of the bolster to
admit oil to the spindle.
The spindle b, b, has fixed on it just above the bolster da conical shaped cup_c, c,
the bobbin or spool a, a, fitting on the top of the spindle at the upper part, and on
the cup c, c, below.
The cup c, c, is made to taper for the following reason:-Should the bobbin a, a,
in time become worn loose at the point of the spindle it can be pushed on a little
further, and it then again fits tight, the top of the spindle being also similarly
tapered or conical. The cup c, c, is also made hollow beneath to serve as a cover
for the bolster d, d, and thus prevent dust or cotton ends or hard waste from
collecting thereon. The cup fits tight on the spindle, but can be removed when it
is required to withdraw the spindle.
ff is a plate placed loosely on the rail g, g, to cover the oil cups. This plate
has small holes drilled through to pour oil into the cups without removing the
plate. On this plate f, f, over each spindle there is a small washer e, e, put on to
cover the oil hole in the said plate. A similar plate and washers f¹ and c¹ are
applied to the footstep also.
Having now described the nature and object of my said Invention, together
with the manner in which the same is to be or may be performed or carried into
practical effect, I wish it to be understood that I do not limit myself to the precise
details given, but I claim as my Invention,-
First. Casting a cup or block in one piece with the bolster (or affixing a block
thereto), such cup or block being so arranged that it can be adjusted by means of
set screws, substantially in the manner and for the purpose above described.
Secondly. Affixing or applying similar blocks to the footsteps for the same
purpose.
Thirdly. Fixing on the spindle a tapered or conical cup, so arranged that when
the bobbin wears in the hole it can be made fast again by pushing it further on to
the spindle, such cap also acting as a cover for the bolster.
In witness whereof, I, the said Ferdinand Henry Ziffer, have hereunto set my
hand and seal, this Ninth day of September, in the year of our Lord One
thousand eight hundred and seventy-eight.
