Improvements relating to the Building Motions of Spinning and like
Frames.
We, JAMES CALVERT, of 17, Garbett Street, Accrington, Foreman, and Messrs
HOWARD AND BULLOUGH LIMITED, of Globe Works, Accrington, Machine Makers,
do hereby declare the nature of this invention to be as follows:-
"The object of our invention is to make long lift bobbins with a gradual taper
finish at the top of the cop or bobbin, with a square bottom and is better for re-
winding as it does not slip off the nose of the bobbin.
Upon the heart I arrange a slide with lip, into which is tapped a screw which
terminates in a bevel wheel gearing (when forming the top of the bobbin) with
bevelled teeth upon one side of a bevel wheel, loose upon the heart boss, a bevel
wheel upon a small horizontal regulating shart upon a swivelled bracket, is pulled
by spring into contact with the loose bevel wheel, a pressure rod is connected
to the cam lever arm, and can be regulated as to its position with same, by its
lower screwed part and nuts and adjustable stud; this bar has a thickened part
which bears against the small horizontal shaft and keeps its wheel out of gear
with the loose bevel wheel until it arrives at the narrowest part, when it allows
it to engage therewith and stops the loose bevel wheel, upon which the bevel
wheel upon the slide is operated, and so operates the slide, raising and so forms
the taper on the top of the bobbin.
For winding back of the plate at any position of the bobbin, I employ a loose
bush on the shaft with a tapered end or edge and a turned down part, so as to
slide upon the shaft and vary its position in relation to the pressure bar, and
so the thick or thin part comes in contact with the pressure bar, the bevel wheel
on the shaft is put in or out of gear at will.
The pressure bar is kept in position by suitable bracket at its top end attached
to the machine frame.

Improvements relating to the Building Motions of Spinning and like
Frames.
We, JAMES CALVERT, of 17, Garbett Street, Accrington, Foreman, and Messrs.
HOWARD AND BULLOUGH LIMITED, of Globe Works, Accrington, Machine Makers,
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;
The object of our invention is to make, or build long lift bobbins in spinning,
winding, doubling and like frames-with a gradual taper finish at the top of the
cop or bobbin, and with a square bottom, at the same time we obtain a solid
nose, not liable to unravel with handling, and we are able to dispense with the
top flange of doubler bobbins and so use bobbins with only one Hange; this is
better for rewinding, as the yarn does not slip off the nose of the bobbin, thus
reducing waste to a minimuni.
DESCRIPTION OF DRAWINGS.
Fig. 1 is an end elevation of part of a winding or doubling frame, with our
improvements applied.
Fig. 2 is a plan of Fig. 1.
Fig. 3 is a front view of Fig. 1.
Fig. 4 is an end view of a modification of means for operating slide or move-
able nose.
Fig. 5 is a plan of Fig. 4.
Upon the heart cam A, or in combination therewith, we arrange a slide B,
with lip C, into which is tapped a screw D, this screw terminates in a bevel
wheel E, gearing (when forming the top of the bobbin) with bevelled teeth F¹
upon one side of a bevel wheel F, loose upon the heart boss.
A bevel wheel G, keyed or fixed upon a small horizontal regulating shaft or
stud H, carried by a swivelled bracket J, is pulled into contact or gear with the
loose bevel wheel F, by means of a spring K, the shaft or stud H is prevented
from revolving preferably by friction in its bearing or other means.
A pressure rod L is connected to the cam lever arm M, such rod being regulated
as to its position, when coming in contact with the shaft H, by means of nuts N
upon its lower screwed part, and clamping screw P; the rod L is adjusted accord-
ing to the diameter of bobbin required to be made.
This rod or bar L has a thickened part R, and is raised and lowered until its
thinner lower part and its thicker upper part are brought alternately opposite
the shaft H, whereby the wheels G F are allowed to move into gear or are
forcibly separated, the wheel G upon engaging with the loose bevel wheel F stops
the same; when this is effected the bevel wheel E upon the slide B, is operated
by the teeth F1 as the cam revolves, and so operates the slide, projecting it
beyond the nose of the cam, and, as the slide comes in contact with the runner A¹
upon the lever M, (to which is also attached the chain M' for giving motion to
the ring rail or lifter plate), it gives an extended lift to the rail when at the
top of its traverse, and so forms the taper on the top of the bobbin, the previous
layer of yarn being held or supported by the subsequent layer for the purposes
aforesaid.
For winding back of the ring rail or lifter plate at any position of the bobbin,
we employ a loose bush S on the shaft H, with a tapered end or edge and a
turned down part T, this part T is connected with means for operating the
bush S, so as to slide upon the shaft H, and vary its position in relation to the
pressure bar L, and, as the thin or thick part of the bush comes in contact with
the pressure bar L, the bevel wheel G, on the shaft H, is put in and out of gear
with the wheel F at will, the sliding part S being operated by the handle U.
and bar U attached to the turned down part T, as desired.
W is a handle employed for operating the shaft H, after being released, for
winding back or adjusting the ring rail or lifter plate, previous to starting the
frame, and, according to the position on the bobbin, it is required to begin wind-
ing, the revolving of the shaft H operates the wheel F, whose teeth F1 act upon
the wheel E, and, as the wheel E becomes blocked (on the sliding nose return-
ing to its starting position) the continued motion of the wheel revolves the
cam for the purposes aforesaid.

page_text: Or, as an alternative to the teeth F, wheel E and screw D), we may employ,
(see Figs. 4 and 5), upon the bevel wheel F, an eccentric ring F, this eccentric
ring works within a notch F2 upon the lip C of the slide or radiating nose B,
so imparting a continuous and automatic movement to the said slide for the
purposes aforesaid.
The pressure bar is kept in position by a suitable bracket V at its top end,
attached to the machine frame.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed we declare that what
we claim is :--
1. In spinning and like frames, the use and employment of a moveable or
radiating nose or slide B, upon or in combination with an ordinary heart or
cam, for the purposes set forth.
2. In spinning and like frames, the combination of wheel G, upon shaft H,
pressure rod or bar L, loose wheel F, having bevelled teeth F¹, gearing with
the wheel E, upon screwed shaft D, for automatically and intermittently oper-
ating the moveable nose or slide B, upon the heart cam A, in the manner and
for the purposes set forth.
3. In spinning and like frames, the combination of the wheel F, and eccentric
ring F, for imparting a continuous and automatic motion to the slide B, upon
the cam A, in the manner substantially as set forth.
4. In spinning and like frames, the use and employment, of a loose or sliding
bush S, upon the shaft H, in the manner and for the purposes set forth.
