Bolton, in the County of Lancaster, Machine Maker, and JAMES MACQUEEN, of the
same Place, Machinist. CERTAIN IMPROVEMENTS IN MACHINES FOR SPINNING AND
DOUBLING."

Our Invention consists, first, in an improved mode of connecting the double
rings of ring and traveller throstle-spinning and doubling frames to the ring rail,
also in the mode of constructing the fly or fluff catchers. Shallow recesses are
made in the ring rail; these recesses are larger in diameter than the ring which is
held in them by three clamps and set screws; the ends of these clamps are made to
fit against the body of the ring, and have slots. to enable them to follow the ring.
By this means the position of the ring can be set to the spindle; and we make
one of the clamps with an angle bracket to act as a fly or fluff catcher to strike the
fibres off the traveller, and as the position of the fly catcher is determined by the
ring no setting is required.
Our Invention consists, secondly, in an improved mode of lubricating the
spindles of throstle spinning and doubling frames; either the footsteps in ordinary
frames, or both bearings of spindles made with bolster and footstep bearings in one
piece, whereby any convenient number of spindles can be lubricated from one oil
chamber.

page_text: We make a groove in the bolster rail or footstep rail, and a similar groove in a
side bar fixed to the rail; or we cut a groove only in the rail and apply a flat side
bar; the recess formed by these grooves or this groove is supplied with oil from a
chamber, the lower end of which is below the level of the recess to collect the
inpurities in the oil.
The oil recess is connected to each spindle by passages in the rail, and in the
bolster or footstep; these passages are also inclined upwards to prevent the
impurities in the oil passing to the spindles.
By this method the height of the oil in the bolsters is easily kept to a proper
level, and the objection that dirt and impuritics collect in the step is satisfactorily
disposed of, and the impurities collected at the bottom of the chamber are easily
removed.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Benjamin Alfred Dobson and James Macqueen in the Great Seal
Patent Office on the 8th November 1878.
BENJAMIN ALFRED DOBSON, of the Firm of Messieurs Dobson and Barlow, of
Bolton, in the County of Lancaster, Machine Maker, and JAMES MACQUEEN, of the
same Place, Machinist. "CERTAIN IMPROVEMENTS IN MACHINES FOR SPINNING AND
DOUBLING."
Our Invention consists, first, in an improved mode of connecting the double rings
of ring and traveller throstle-spinning and doubling frames to the ring rail, also
in the mode of constructing the fly or fluff catchers.
And, secondly, in an improved mode of lubricating the spindles of throstle-
spinning and doubling frames, either the footsteps in ordinary frames, or both
bearings of spindles made with bolster and footstep bearings in one piece, whereby
any convenient number of spindles can be lubricated from one oil chamber.
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, reference
being had to the figures and letters marked thereon.
Figs. 1 and 2 illustrate the first part of our Invention. In these views g is the
ordinary ring rail of a ring and traveller spinning and doubling frame, and is a
ring of tho usual construction. Each ring is secured to the ring rail by three
clamps i, the inner ends of which fit against the body of the ring, and they are
provided with slots for the holding-down screws j. The lower flange of the ring h
fits in a shallow recess in the ring rail, and these recesses are larger in diameter than
the flange of the ring; by this means the centre of the ring can be set to coincide
with the centre of the spindle. One of the clamps i of each ring is turned up or
made with an angle bracket h, which acts as a fly or fluff catcher to strike the fibres
off the traveller m. As the position of this fly catcher is determined by the ring,
no setting or adjusting of the fly catcher to the ring is required.

page_text: Figs. 3 and 4 illustrate the second part of our Invention. In these views n is
the spindle, which is supported in the footstep 2, screwed into the rail w and in the
bolster bearing 7, fixed in the tube r, which is screwed in the bolster rail 8; the
spool or bobbin t fits above on the spindle n, and below in the cup u, which is either
fixed to or made in one one piece with the wharve v; this wharve is provided with a
long hollow bush fitting on the spindle . This mode of supporting the spindle and
the spool or bobbin forms no part of our Invention.

At the under side of the rail s is a groove, and a similar groove is mado in tho
rail w. The recess formed by these grooves is supplied with oil from the chambers y,
which are screwed into the rail w; the lower ends of the chambers y are below tho
level of the recess to collect the impurities in the oil.
The oil recess is connected to the bolsters and footsteps of the spindles, and any
convenient number of the chambers y may be used. A tap is placed at the
bottom of each chamber y to discharge the impurities when required.
By this method the height of the oil in the bolsters is easily kept to a proper
level, and the objection that dirt and impurity collect in the steps is satisfactorily
disposed of, while the impurities collected at the bottom of the chamber are easily
removed.
Fig. 5 represents a modification of this part of our Invention. The rails is
recessed below, and below it is the plates; the tuber contains the bolster q, as in
Fig. 4, but it extends through the rails and plate 2, and is secured to them by the
nut ; the lower end of the tubo r forms the footstep p. The oil is supplied to
the recess in the rails by chambers y, as before, and it enters the tubes by the
side passages ¹.
Fig. 6 represents a modification of Fig. 5. In this view the recess for the oil is
made in the plate z', which is screwed to the side of the rails, and the oil passes
through the passages 2 to the spindles.
Fig. 7 represents our improved method of oiling the footsteps alone. The rail s
has a recess, as before, and the plate is held to it by screw; the oil enters the
footstep p from below at the centre, and passes upwards and returns into the recess
through the hole ³.
Having thus stated the nature of our Invention, and described the manner of
performing the same, we declare that we claim,-
First. Making the recesses in the ring rail larger than the flanges of the rings for
the purpose of adjustinent, as shewn and described in reference to Figs. 1 and 2.
Secondly. Making the fluff catcher of one piece with the clamp for holding the
ring, as shewn and described in reference to Figs. 1 and 2.
And, Thirdly. The improved modes of lubricating any convenient number of the
bolsters and footsteps of spindles from one oil chamber, as shown and described in
reference to Figs. 3, 4, 5, 6, and 7.
In witness whereof, I, the said James Macqueen, for myself and on behalf of
the within-named Benjamin Alfred Dobson, have hereunto set my hand and
seal, this Second day of November, One thousand eight hundred and
seventy-eight,
JAMES MACQUEEN. (L.S.)
