PROVISIONAL SPECIFICATION.
Improvements in Machines or Frames for Roving and Twisting
Fibres.
We ARTHUR WILSON METCALFE, of Glass House Mill, Pateley Bridge in the
County of York, Flax Spinner, and WILLIAM JOHN HENNING of the same place,
Preparing Master, do hereby declare the nature of this invention to be as
follows:-
This invention relates to machines, or frames used for roving, slubbing, and gill
spinning of flax, and other fibres.
It is mainly intended for producing what is called in the flax trade "double
rove upon one roving bobbin.
"
The usual manner in which this is accomplished is to put the separate bobbins of
rove up together at the spinning frame.
The method we propose to adopt is to combine these two, or more, rovings
together at the roving frame, and for that purpose we adopt the following
arrangement.
In front of the boss roller or drawing roller we fix a diagonal plate such as is
used in drawing frames in order to combine the slivers from two or more gills into
one delivery, these slivers we pass through a conductor, and two pressing, or
calender rollers, in the manner usual to drawing frames, from whence the sliver is
twisted, and put on the bobbin in the ordinary way.
By a different arrangement of the delivery rollers from that above described we
may pass the combined sliver under the bottom delivery roller, half round, and
between it, and the pressing roller, over the top of the pressing roller, and thence
to the spindle, this arrangement being similar to that frequently used in twisting
frames for yarns. In this case in order to relieve the rove from strain due to
backlash on the spindles and gearing we make the top roller capable of swinging
backwards and forwards upon the bottom roller so that, on the rove tightening
from any cause, the top roller, over which the rove passes, can swing forward
and give relief, the reverse action also taking place with the slackening of the
rove.

COMPLETE SPECIFICATION.
Improvements in Machines or Frames for Roving and Twisting
Fibres.
We, ARTHUR WILSON METCALFE, of Glasshouse Mill, Pateley Bridge, in the
County of York, Flax Spinner, and WILLIAM JOHN HENNING, of the same place,
Preparing Master, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
This invention relates to machines or frames used for roving, slubbing, and gill
spinning of flax and other fibres.
It is mainly intended for producing what is called in the flax trade "double
rove" upon one roving bobbin.
The usual manner in which this is accomplished, is to put the separate bobbins
of rove up together at the spinning frame.

page_text: The method we propose to adopt is to combine these two or more rovings
together at the roving frame, and for that purpose we adopt the following
arrangement.
In front of the boss roller or drawing roller, we fix a diagonal plate such as is
used in drawing frames, in order to combine the slivers from two or more gills into
one delivery; these slivers we pass through a conductor, and two pressing or
calender rollers, in the manner usual to drawing frames, from whence the sliver is
twisted and put on the bobbin in the ordinary way.
By a different arrangement of the delivery rollers from the above described, we
may pass the combined sliver under the bottom delivery roller, half round, and
between it and the pressing roller, over the top of the pressing roller, and thence
to the spindle; this arrangement being similar to that frequently used in twisting
frames for yarns.
In this case in order to relieve the rove from strain due to
"blacklash on the spindles and gearing, we make the top roller capable of
swinging backwards and forwards upon the bottom roller, so that on the rove
tightening from any cause, the top roller over which the rove passes can swing
forward and give relief; the reverse action also taking place with the slackening
of the rove.
Such being the nature and object of the said invention, the following is a
complete description of same, reference being had to the accompanying drawings
forming a part of this Specification, and in which similar figures of reference refer
to similar parts throughout.
Fig. 1 is a sectional end elevation of the front part of an ordinary roving or gill
spinning frame, having our improvements applied thereto.
Fig. 2 is a sectional end elevation of the front part of an ordinary roving or gill
spinning frame, having our improvements applied thereto.
Fig. 3 is a plan view of Fig. 2 with the pressing rollers removed, in order more
clearly to show the sliver passing from the gills.
According to this invention, and referring inore particularly to Fig. 1 of the
drawings. At 1 is the ordinary drawing roller with the pressing roller 2 above it.
At 3. 3 are the spindles and flyers of the ordinary kind. Upon an extension of
the carriage plate 4, is mounted a front or delivery roller 5, with pressing rollers 6.6
above it, said pressing rollers 6. 6 being maintained in correct position by means of
the brackets or bearings 7. At 8 is the sliver doubling plate which is similar to
the doubling plate used in flax drawing frames.
In Figs. 2 and 3 the parts are arranged in a manner similar to those in Fig. 1,
but the rove 9 passes from between the rollers 1. 2, to and under the roller 5, round
the front, and between the rollers 5 and 6, thence over the top of the roller 6, to the
flyer 3, whereby it is twisted in the ordinary manner.
The pressing roller 6 is maintained in position above the roller by means of
the bearings or brackets 7. 7, the lower ends or arms of which are pivoted at 10,
and capable of swinging backwards and forwards, but are steadied and a certain
amount of friction or resisting power put upon them by means of a counterbalance
weight below, or by means of the spring 11 adjustable by means of the nuts 12 on
the screw which passes through the plate 13.
When any extra tension caused by "backlash" of the gear is put upon the
rove 9, the roller 6 can move forward to the position shewn by dotted lines at 6',
and thus relieve the strain whereon the counterbalance weight or spring 11 will
move the roller 6 to its normal position.
At 15 are the ordinary gills, and the slivers are drawn from the gills 15 by the
drawing rollers as ordinary. The alternate slivers 16. pass from the gill 15 down
through the diagonal slots 17 in the sliver plate 8, and under the latter and the
alternate slivers 18, pass from the gills 15 direct to the drawing rollers, and the
sliver 16 passing up through slots 17, the two slivers are united at the delivery
rollers 5. 6, and form the double rove 9 as delivered to the spindles and flyers 3.
By the means herein described, two or more slivers can be united in one rove.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
(1.) The sliver plate having diagonal slots 17. 17, and the front delivery
rollers 5. 6 introduced between the drawing rollers 1. 2, and the spindles and
flyers 3, as and for the purpose herein described, and substantially as illustrated by
Fig. 1 of the accompanying drawings.
(2.) The front delivery and pressing rollers 5. 6, the pressing roller 6 being
carried in bearings or brackets 7, having counterbalance weight, or adjustable
spring, as and for the purpose herein described, and substantially as illustrated by
Figs. 2 and 3 of the accompanying drawings.
