Year: 1877

page_text: LETTERS PATENT to Thomas Henry Rushton, 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, for the Invention of "IMPROVEMENTS
IN MACHINERY FOR SPINNING AND DOUBLING."
Sealed the 7th December 1877, and dated the 10th October 1877.
PROVISIONAL SPECIFICATION left by the said Thomas Henry. Rushton and
James Macqueen at the Office of the Commissioners of Patents on the 10th
October 1877.
THOMAS HENRY RUSHTON, 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. "IMPROVEMENTS IN MACHINERY FOR SPINNING AND
DOUBLING."
Our Invention is applicable to those ring and traveller throstle spinning and
doubling frames in which the spindle is supported by a tube fixed in the bolster
rail, and passing inside the bobbin or spool, and it consists in certain improved
arrangements of machinery for facilitating the doffing of the full bobbins or spools.
In performing our Invention we employ a bush, the upper end of which has a
conical hole fitting on the spindle, and the lower end fitting on the tube fixed in
the bolster rail. When the bobbins or spools have been filled the bushes are all
lowered by the action of a horizontal bar provided with inclines and springs, or
other equivalents; the bush is then carried round by the friction of the spindle,
while the ring rail is lowered to wind a few coils of yarn or thread around the lower
end of the bush. After the full bobbins or spools have been doffed and empty ones
put in their places, the ring rail is lifted to bring the yarns or threads on to the
Prine R71

page_text: bobbins or spools, on to which they are wound as usual; the horizontal bar above
referred to must now be moved to cause the inclines and springs to raise and stop
the bushes, which remain stationary until another doffing is required.
By means of this Invention we can use plain tubes fixed to the bolster rail, and
allow the oil to run down the outside of the tube back into the cup fixed to the
spindle, as described in the Provisional Specification of Letters Patent applied for
by the within-named James Macqueen, in conjunction with Benjamin Alfred
Dobson, on the 24th day of July 1877, Number 2826; the bush being outside the
tube prevents the oil coming in contact with the bobbin or spool.
Another advantage is, that by stopping the bush when it is not required to run, a
considerable saving in power is effected, and the yarn or thread that has been
wound on the bush while doffing can be removed while the frame is running,
thereby preventing the loose ends from forming fly and catching the oil.
Our Invention may be modified by connecting and disconnecting the bush to and
from the bobbin or spool by a cone or otherwise.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Thomas Henry Rushton and James Macqueen in the Great Seal
Patent Office on the 6th April 1878.
THOMAS HENRY RUSHTON, 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. "IMPROVEMENTS IN MACHINERY FOR SPINNING AND
.DOUBLING."
The nature of our Invention consists in certain improved arrangements of
machinery for facilitating the doffing of the full bobbins of those ring and traveller
throstle spinning and doubling frames in which the spindles are supported by long
tubes fixed to the bolster rail, and passing inside the bobbin or spool.
And in order that our Invention may be fully understood we will proceed to
describe the accompanying Sheet of Drawings.
Fig. 1 represents a spindle for a ring and traveller throstle spinning and doubling
frame, which is supported in a tube fixed to the bolster rail, and passing inside the
bobbin or spool.
Figs. 2 and 3 represent our improved arrangement of machinery for facilitating
the doffing of the full bobbins or spools.
In Fig. 1 a is the spindle; b, the ring rail; c, the bolster rail; d, the footstep
rail; and e, the footstep; fis the long tube or bolster fixed in the bolster rail c; gis
the bobbin or spool fitting on the spindle a on which the yarn is wound; and i, the
oil cup fixed to the spindle.
Our Invention consists in the application of the bush to the spindles a, this
bush is only carried round by the spindle when the yarn is being wound on the

page_text: braid, which is fixed to its lower end; the upper end of the bush 7 has a conical
hole fitting on the spindle a, and the lower end is fixed in the braid ' fitting on
the tube fixed in the bolster rail c. When the bobbins or spools have been filled
the bushes are all lowered by the action of the horizontal bar n, shewn also in
Figs. 2 and 3. This bar is connected by the link n to the lever n³ fixed on the
same shaft as the weighted lever o. The bar n is provided with inclines n' or other
equivalents; the bushes are then carried round by the friction of the spindle, while
the ring rail b is lowered to wind a few coils of yarn or thread around the braids l'.
After the full bobbins or spools have been doffed, and empty ones put in their
places, the ring rail b is lifted to bring the yarns or threads on to the bobbins or
spools g, on to which they are wound, as usual; the horizontal bar n above referred
to must now be lifted by the attendant acting on the weighted lever o or other
equivalent to cause the inclines n' or other equivalents to raise the bar n and stop
the bushes by removing them from contact with the spindle; the bushes and the
braids remain stationary until another doffing is required. The pin projecting
from the bar n comes in contact with the pin projecting from the braid /', and
prevents it revolving, or the pins may be dispensed with and the threads cut by a
knife.
By this means we can use the bolster bearings shewn in Fig. 1, and allow the
oil to run down the outside of the tube f back into the cup i fixed to the spindle;
the bush being outside the tube f prevents the oil coming in contact with the
bobbin or spool.
Another advantage is that by stopping the bush when it is not required to run,
a considerable saving in power is effected, and the yarn or thread that has been
wound on the braid while doffing can be removed while the frame is running,
thereby preventing the loose ends from forming fly, and catching the oil.
Fig. 4 represents a spindle for a ring and traveller throstle spinning and
doubling frame, to which the improved mode of lubricating described in the
Specification of Letters Patent granted to Benjamin Alfred Dobson, and the within-
named James Macqueen, on the 24th day of July 1877, No. 2826, is applied, and
shewing the bolster tube f carried upwards within the bobbin g, and the bush
with braid ', as shewn and described in reference to Fig. 1.
Our Invention may be modified, as shewn in Fig. 5, by connecting and dis-
connecting the braid to and from the bobbin or spool. a is the spindle; f, the
bolster tube; g, the bobbin or spool; c is the bolster rail; all of which are madé as
shewn in Fig. 4; is the doffing braid, to which are attached the springs ; fis
a collar, free to turn on the bolster tube f, but held from moving up or down, as
shewn, or otherwise; n' is a pin in the rail n, bent so as to project over the flange
of the braid l¹.
When it is desirable to doff, the attendant, by moving the weight o or other
equivalent, brings down the rail n, and the pin n catching the flange of the braid l¹
brings it with it, the swell on the springs then acting on the collar f¹ expands
the springs, and connects them with the inside of the bobbin or spool g, as shewn,
and turns round the braid '; after doffing, the rail n is lifted, as before described,
and the braids being disconnected from the bobbin or spool cease to revolve until
the contact is again formned, as described above.
Having thus stated the nature of our Invention, and described the manner of.
performing the same, we wish to remark that we do not intend to limit ourselves
to the details given, as they may be considerably varied or modified, and we
declare that we claim,-
First. The application of the bush to the spindles of machines for spinning and
doubling, which bush is fixed to the braid ", and is connected to the spindle
and disconnected therefrom when required in the manner and for the purposes
described.
Secondly. The application of a spring cone or other equivalent for connecting

page_text: and disconnecting the bobbin or spool to and from the braid ', as shewn and
described.
In witness whereof, we, the said Thomas Henry Rushton and James Macqueen,
have hereunto set our hands and seals, this Fourth day of April, One
thousand eight hundred and seventy-eight.
