IMPROVEMENTS IN CAP SPINNING FRAMES AND IN APPARATUS CONNECTED THEREWITH
Year: 1885

page_text: I, JOHN LEEMING of North Vale Works Bradford in the County of York,
Machine Maker do hereby declare the nature of this invention for IMPROVEMENTS
IN CAP SPINNING FRAMES AND IN APPARATUS CONNECTED THEREWITH to be as
follows:-
This invention relates to certain improvements in the method of overcoming
the varying tension of driving bands used in cap spinning and twisting frames.
Hitherto various devices have been designed for this purpose, perhaps the best
known is that in which the tension is attempted to be equalized by passing the
bands over pullies or rollers having a counter balance weight.
The difficulty however in the efficient accomplishment of this object is the fact
that in the case of cap spinning, the wharl has to travel from one position to
another and in so doing the tension may be equalized but it is done to the detri-
ment of the tape or band inasmuch as it does not run in the centre of the wharl
but it is forced down on to the bottom flange and then up on to the top flange.
In carrying out my invention I employ two fixed rails both bushed to receive
the spindle: the two rails are at such a distance apart as to admit of the traverse
required. Upon the upper side of the top rail I place my stationary, as regards
position, wharl with the ordinary metal tube made fast to it. The metal tube thus
revolves round the spindle in the ordinary way the spindle does not revolve but is
traversed along with the cap in the bushes by means of the lifter motion.
The above is only one mode of carrying my invention into practise. I will now
describe a second method which is a modification of the first as follows:-
To the wharl which in my improvement is always in the same position, I cast or
secure a flange of sufficient diameter to allow of the securing of two vertical guide
rods, of the length equal to the necessary traverse they pass through the lifter rail.
The metal tube on which the bobbin or other on which the yarn is built up, is
placed, is provided with a flange at the bottom of the same and of about the same
diameter as the before mentioned flange secured to the wharl; through this flange
are two holes made corresponding with the two vertical guide rods.
The flange
secured to the wharl revolves and with it the two guide rods thus giving motion
to the metal tube. The ordinary lifter rail being placed below the flange of the
metal tube thus traversing the metal tube as is required.

Connected therewith.
I, JOHN LEEMING, of North Vale Works, Bradford, in the County of York,
Machine Maker, 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 certain improvements in the method of overcoming the
varying tension of driving bands used in cap spinning and twisting frames.
Hitherto, various devices have been designed for this purpose, perhaps the best
known is that in which the tension is attempted to be equalized by passing the
bands over pullies or rollers having a counterbalance weight; the difficulty how-
ever in the effective accomplishment of this object is the fact that the wharl has
to travel from one position to another, and in so doing, the tension may be equalized
but is done to the detriment of the tape or band inasmuch as it does not run in
the centre of the wharl but presses against the bottom flange in one portion of the
traverse and on the top flange in another portion.
My invention consists in mounting the wharls on non-rotating spindles and
securing to each wharl two guide rods which extend in a vertical direction through
a flange of the metal tube on which the bobbin or spool is placed. The said flange
rests upon the lifter rail which moves up and down in the ordinary manner but in
so doing causes the revolving metal tube to traverse along with it thus building
the yarn on the bobbin or spool with the wharl at the same elevation in all portions
of the traverse, and the driving band or tape in the centre of the wharl.
In order that my invention may be better understood I have appended a sheet
of drawings illustrative thereof, in which Fig. 1 represents a front elevation of a
spindle with the driving wharl and tube mounted thereon according to my inven-
tion, the cap, which is of the ordinary description being removed, Fig. 2 is a vertical
section through the cap, metal tube, wharl, and rails, and the two vertical guide
rods partly in section, and Fig. 3 is a plan of the metal tube. In all the figures
similar letters represent similar parts.
The driving cylinder and other portions of the spinning or twisting frame not
shewn in the drawings, are arranged and actuated in the same manner as in all
ordinary frames, therefore do not require any explanation or illustration thereof.
The bottom rail A is attached to the framework, and the non-rotating spindles B
are secured in the said rail in the usual manner. Instead of making the spindles
parallel for the whole distance above the top surface of the rail A, I make them
thicker for some distance at B¹ upon which I mount the wharls C each of which
rests upon a washer or collar D. On the top side of the wharl I form a boss upon
which is secured the two vertical guide rods E which pass through an opening in
the lifter rail F and through small holes H in the flange of the metal tube G, thus
when the wharl is in motion causing the tube G and the bobbin or spool thereon
to rotate, the latter being driven by the usual pins in the tube flange.

page_text: The band or tape from the driving cylinder passes around the groove of each
wharl C thus giving motion to the same and to the guide rods E and metal tube G,
the flange of the latter resting on the lifter rail F operated in the usual manner,
causes the revolving metal tube G to traverse up and down the non-rotating
spindle B thereby building the yarn on to the said bobbin or spool; the wharl
rotating, rests upon the collar or washer D on the fixed bottom rail and remains at
the same elevation in whatever position the lifter rail F may be.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
The combination of a wharl with vertical arms and metal tube such as G
mounted on a non-rotating spindle, the whole operating as, and constructed,
substantially in the manner and for the purpose set forth.
A rotating wharl with which are combined the vertical arms for operating a
flange tube such as G for the purpose described.
