Year: 1872

page_text: LETTERS PATENT to John Elce, of Manchester, in the County of
Lancaster, Machine Maker, and Henry Birkby Arundel, of the same
Place, Manager, for the Invention of "IMPROVEMENTS IN MACHINERY
FOR PREPARING COTTON AND OTHER FIBROUS SUBSTANCES.
PROVISIONAL SPECIFICATION left by the said John Elce and Henry
Birkby Arundel at the Office of the Commissioners of Patents, with
their Petition, on the 14th October 1872.
We, JOHN ELCE, of Manchester, in the County of Lancaster, Machine
Maker, and HENRY BIRKBY ARUNDEL, of the same Place, Manager,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
MACHINERY FOR PREPARING COTTON AND OTHER FIBROUS SUBSTANCES," to be as
follows:-
In slabbing, roving, and intermediate frames and other machines of the
like nature it is usual to employ a swing vibrating between the driving
shaft and the copping rails, and this swing supports the carrier wheels
for transmitting the motion from the driving shaft to the shafts for

page_text: driving the bobbins.
As the copping rail moves up and down these
wheels roll on their axis and cause an uneven winding; now our Inven-
tion consists in so arranging the driving wheels that this rolling is
avoided or counterbalanced and a perfectly uniform winding is obtained.
To effect this object a bevel wheel on the driving shaft driven through
the differential motion gears into another bevel wheel loose on a diagonal
shaft which swivels round a fixed bush concentric with the driving shaft ;
on the other end of the diagonal shaft is a bush supporting another
bevel wheel which is connected to the top bevel wheel by keys and
grooves; this lower bevel wheel gears into a bevel wheel on the horizontal
shaft. for driving the bobbins; this bevel wheel being placed on the
opposite side of the diagonal shaft to that on the driving shaft produces
the compensation required to effect a perfect winding of the sliver or
roving. The particular arrangement of the machinery may be modified.
The bobbins instead of being driven by skew wheels and two horizontal
shafts as usual we now drive by one horizontal shaft and bevel or mitre
pinions, each pair of which drives a spur wheel gearing into two of the
spur bobbin pinions, one on each side of the centre shaft, thus dispensing
entirely with skew gearing and with one horizontal shaft.
SPECIFICATION in pursuance of the conditions of the Letters Patent
filed by the said John Elce and Henry Birkby Arundel in the Great
Scal Patent Office on the 14th April 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN ELCE,
of Manchester, in the County of Lancaster, Machine Maker, and HENRY
BIRKBY ARUNDEL of the same Place, Manager, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourteenth day of October, in the year
of our Lord One thousand eight hundred and seventy-two, in the thirty-
sixth year of Her reigu, did, for Herself, Her heirs and successors, give
and grant unto us, the said John Elce and Henry Birkby Arundel, Her
special licence that we, the said John Elce and Henry Birkby Arundel,
our executors, administrators, and assigns, or such others as we, the said
John Elce and Henry Birkby Arundel, our executors, administrators, and
assigns, should at any time agree with, and no others, from time to time

page_text: and at all times thereafter during the term therein expressed, should and
lawfully might make, use, exercise, and vend, within the United
Kingdom of Great Britain and Ireland, the Channel Islands, and Isle
of Man, an Invention for "IMPROVEMENTS IN MACHINERY FOR PREPARING
COTTON AND OTHER FIBROUS SUBSTANCES," upon the condition (amongst others)
that we, the said John Elce and Henry Birkby Arundel, our executors
or administrators, by an instrument in writing under our, or their, or
one of our or their hands and seals, should particularly describe and ascer-
tain the nature of the said Invention, and in what manner the same
was to be performed, and cause the same to be filed in the Great Scal
Patent Office within six calendar months next and immediately after
the date of the said Letters Patent.
NOW KNOW YE, that we, the said John Elce, and Henry Birkby
| Arundel, do hereby declare the nature of our said Invention, anḍ, in what
manner the same is to be performed, to be particularly described and
ascertained in and by the following statement (that is to say) :-
:-
In slubbing, roving, and intermediate frames and other machines of the
like nature it is usual to employ a swing vibrating between the driving
shaft and the copping rail, and this swing supports the carrier wheels for
transmitting the motion from the driving shaft to the shafts for driving
the bobbins. As the copping rail moves up and down these wheels roll
on their axes and cause an uneven winding. Now our Invention consists
in so arranging the driving wheels that this rolling is avoided or counter-
balanced and a perfectly uniform winding is obtained. The bobbins
instead of being driven by skew wheels and two horizontal shafts as
usual, we now drive by one horizontal shaft and bevel or mitre pinions,
each pair of which drives a spur wheel gearing into two of the spur
bobbin pinions, one on each side of the centre shaft, thus dispensing
entirely with skew gearing and with one horizontal shaft.
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 is an elevation partly in section of a roving frame to which our
improvements are applied; Fig. 2 is a plan of part of the same; Figs. 3
and 4 are detached views of part of our Invention.
a is the driving shaft; b, a bevel wheel which is driven through and
forms part of the differential motion; c, the roller beam; d, the drawing

page_text: rollers; e, the bottom rail; f, the copping rail; f, the end slide; and g, g,
the spindles; all these parts and the others requisite to complete the frame
and which are not described hereafter are made in the ordinary manner.
The bevel wheel b is provided with a long boss or tube to which is keyed
the bevel wheel which gears into another bevel wheel loose on the
diagonal shaft i which has a bridle swivelling on the fixed bush j
which is concentric with the driving shaft a. This diagonal shaft i does
not revolve. At the lower end of the shaft i is the bush P, see Fig. 3, on
which fits the bevel wheel & which is provided with a long boss fitting over
the boss of the wheel hand connected to it by keys taking into grooves,
by which arrangement the wheel transmits motion to the wheel k,
while at the same time the bosses of the two wheels may slide in or out
like the tubes of a telescope; the bush which supports the lower end of
the diagonal shaft i is fixed in the socket which swivels in bearings fixed
to the end slide ƒ', and the wheel k gears into the wheel on the shaft
by which the bobbin pinions are driven, as will be explained hereafter.
The wheel is held in gear with the wheel & by the collar fixed on
the shaft i, and the wheel is held in gear with the wheel by the collar
on the bush i². As the bevel wheel is placed on the opposite side of
the diagonal shaft i to that of the wheel b' on the driving shaft a it is
evident that as the copping rail moves up and down to distribute the
rovings on the spools or bobbins the retarding action caused by the
rolling of one pair of wheels is compensated for by the accelerating
action of the other pair and consequently a perfectly uniform winding
takes place. This mode of communicating motion from the driving
shaft to the shaft by which the bobbin pinions are driven may be
applied to roving and other similar frames in which one or two shafts
and skew wheels and pinions are employed to drive the bobbin pinions.
Our improved machinery for driving the bobbin pinions consists of the
mitre pinions fixed on the shaft ; these pinions gear into similar
pinions m which are cast or fixed to the spur wheels m², and each spur
wheel m' gears into two pinions n which carry the bobbins round, one
on each side of the shaft . By this means the skew gearing usually
employed is dispensed with, and one horizontal shaft gives motion to
both rows of bobbins; similar gearing is applied to the bobbin rail e for
driving the spindles. The copping rail is counterbalanced by the long
weight o which is suspended to chains fixed to the pulley o' cast with or
close to the rack pinions o*.

page_text: Having thus stated the nature of our Invention and described the
manner of performing the same, we declare that we claim,-
First. The telescope wheels h and k and the parts acting in com-
bination therewith for driving the shaft or shafts by which the bobbin
pinions are driven, as shewn and described.
And Secondly. The improved mode of driving the bobbin pinions
and spindles when used in combination with the mode of communicating
motion from the driving shaft a to the shaft l, as shewn and described.
In witness whereof, I, the said Henry Birkby Arundel, for myself
and on behalf of the said John Elce, have hereto set my hand
and seal, this Tenth day of April, One thousand eight hundred
and seventy-three.
