IMPROVEMENTS IN APPARATUS FOR LUBRICATING FOOTSTEPS AND SPINDLES
Year: 1877

page_text: LETTERS PATENT to John Greenwood, of Oldham, in the County of Lancaster,
Cotton Carder, and Holland Taylor, of the same Place, Machine Maker, for the
Invention of "IMPROVEMENTS IN APPARATUS FOR LUBRICATING FOOTSTEPS
AND SPINDLES."
Scaled the 30th November 1877, and dated the 18th August 1877.
PROVISIONAL SPECIFICATION left by the said John Greenwood and
Holland Taylor at the Office of the Commissioners of Patents on the 18th
August 1877.
JOHN GREENWOOD, of Oldham, in the County of Lancaster, Cotton Carder,
and HOLLAND TAYLOR, of the same Place, Machine Maker. "IMPROVEMENTS IN
APPARATUS FOR LUBRICATING FOOTSTEPS AND SPINDLES."
Our Invention is applicable to the machines for preparing cotton and other fibrous
materials, known as slubbing, intermediate, and roving frames, and it consists in an
improved mode of lubricating the footsteps and spindles of such machines, whereby
the lubricating material and the labour of applying it are considerably reduced; the
lubricating material is also prevented from being thrown out of the footstep by the
centrifugal force of the revolving spindle.
In performing our Invention we cover the lower part of the spindle with a conical
tube of metal, the lower end of which tube fits in a recess in the footstep; this
tube prevents the escape of the lubricating material and also prevents any dirt or
fibres accumulating in the footstep.

the said John Greenwood and Holland Taylor in the Great Seal Patent Office
on the 16th February 1878.
JOHN GREENWOOD, of Oldham, in the County of Lancaster, Cotton Carder,
and HOLLAND TAYLOR, of the same Place, Machine Maker.. "IMPROVEMENTS IN
APPARATUS FOR LUBRICATING FOOTSTEPS AND SPINDLES."
Our Invention is applicable to the machines for preparing cotton and other fibrous
materials, known as slubbing, intermediate, and roving frames, and it consists in an
improved mode of lubricating the footsteps and spindles of such machines, whereby
the lubricating material and the labour of applying it are considerably reduced; the
lubricating material is also prevented from being thrown out of the footstep by the
centrifugal force of the revolving spindle.
In performing our Invention we cover the lower part of the spindle with a conical
tube of metal; the lower end of which tube fits in a recess in the footstep, this tube
prevents the escape of the lubricating material, and also prevents any dirt or fibres
accumulating in the footstep.
And in order that our Invention may be fully understood and readily carried
into operation, we will proceed to describe the accompanying Sheet of Drawings.
Fig. 1 represents an ordinary spindle of a slubbing or intermediate frame, with
our improved lubricating footstep; the upper part of the footstep is carried upwards
to form a chamber for the oil or other lubricant, and to receive the lower end of the
conical tube a, the upper end of which is of sufficient diameter to allow the spindle
to revolve freely without touching it. When the spindle is at work this conical
tube prevents the lubricating material being thrown out by centrifugal force,
thereby economising the lubricating material, and it also prevents any dirt or fibres
accumulating in the footstep.
Fig. 2 represents the spindle of a roving frame with our improved lubricating
footstep in this case the conical tube a is rather longer than in the previous
Figure, but the length of the tube a may be varied according to circumstances.
Fig. 3 represents a modification of our Invention; in this case the lubricating
material is kept in the footstep, and the dirt and fibres excluded by the flat cover a,
which fits outside the footstep.
We wish it to be understood that we do not intend to limit ourselves to the
details given, as the same may be varied according to the peculiar construction
of the machine to which our improvements are applied, and that we clain,-
The conical tube a, or its equivalent, when applied to the footsteps of spindles for
slubbing, intermediate, and roving frames, in the manner and for the purposes
described.
We also claim the chamber or recess in the footstep in which the tube or its
equivalent fits, or to which it is attached.
In witness whereof, we, the said John Greenwood and Holland Taylor, have
hereunto set our hands and seals, this Fourteenth day of February, One
thousand eight hundred and seventy-eight.
