I WILLIAM BODDEN of Hargreaves Works, Oldham in the County of Lancaster
Spindle 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 :-
3
This invention is an improvement relating more especially to such spinning devices
as are secured to a single spindle supporting rail and also to that class of spinning
devices the rotating parts of which are so supported that they may be deflected to a
certain extent by the effect of an unbalanced load, and it consists of the construction;
and combination of parts as hereinafter set forth.
My invention is illustrated in the accompanying drawings, in which Fig. 1. is an
elevation, partly in central vertical section, of a single rail spinning spindle. with the
supports therefor. Fig. 2 is an elevation of the spindle with a sleeve whirl attached
thereto. Fig. 3 is an elevation of that form of step support which I prefer to use.
Fig. 4. is a central sectional elevation of a spindle footstep with a portion of the
spindle that is supported therein and Fig. 5 is a plan of said footstep.
Figs. 6, 7 and 8 illustrate a modification of the invention hereinafter more
particularly referred to.
Similar reference numbers refer to similar parts in all of the views.
In the drawings, 1 represents the bolster bearing support, which is preferably.
provided with the external collar 2, a nut 3. and the washer 4, the; said nut engaging

page_text: with a screw thread upon the exterior of the said support. I prefer to form an oil
chamber 5 in the upper part of the collar 2 as shown and to form an oil conduit 6
through the side of the support 1. and communicating with the said chamber.
Whenever it may be desired to do so, a washer 18. may be placed encircling the
elevated part 7. of the bolster bearing support and covering the top of the oil
chamber 5. in the usual manner.
At the base of the support 1. is secured the step case 8. in any convenient manner
the construction which I prefer being shown in the drawing.
This preferred form of step case is provided with a sleeve 9, screw threaded in its
interior and which engages with a screw thread upon the surface of the support 1.
The step case of this form is usually provided with flattened surfaces 10, which are
adapted to receive a wrench.
Below the bottom of the threaded part of the sleeve 9. is the step well 11. in which
the footstep 12 is supported.
The footstep 12 is made of such a size with respect to the other parts of the
structure and of such a form that it may be moved laterally to a slight extent in all
directions, and it is preferably provided with one or more oil holes 13, leading from
the space surrounding the step to the cavity in the interior thereof in which the
spindle is supported.
The said cavity is preferably made of the shape of the spindle and also a little
larger than the said spindle, as shown in Fig. 4. or in other words the spindle prefer-
ably fits loosely in the said footstep.
I also make the step well 11. so deep that several discs or washers 14. may be
placed therein below the bottom of the footstep 12. These discs or washers may be
made of any suitable material but I prefer to form one or more of the lower discs in
the series of leather, or some other elastic material in order to prevent the vibrations
induced in the spindle footstep 12 by the spindle 15 from being communicated to the
bolster bearing support 1. and thence to the spindle supporting rail 16.
It is preferable that one or both of the surfaces in contact at the bottom of the
footstep 12. that is the bottom of the said footstep and the top of the uppermost of
the discs 14. should be plane, to the end that the said footstep may easily yield
laterally to a slight extent and with equal freedom in all directions, upon the applica+
tion of a force thereto in a lateral direction..
The modification illustrated by Figs. 6. 7 and 8. may be employed in cases wherein
it is preferred to positively prevent the footstep 12 from rotating with the spindle in
which case one or more slots 20 are made in the sides of the footstep 12 and one or
more locking pins 19 are inserted through the side of the step case 8. the inner ends
of the said pins engaging with the said slots.
An equivalent lock for preventing the footstep 12 from rotating may sometimes be
substituted for the one illustrated.
The lower part of the spindle 15 is preferably made of a small diameter and
terminating in a sharp point although any other suitable construction of these parts.
may be adopted at the will of the maker of the device, to meet any unusual require-
ments.
When the lower end of the spindle is made of a small diameter as shown the spindle
increases in diameter as the bolster bearing is approached from its lower end.
The bolster bearing is preferably cylindrical. The spindle is preferably provided
with a sleeve whirl, the plane of whose band groove crosses the said bearing in its
bolster.
The fit of the spindle 15 in its bolster bearing should be a rather loose one in order
that the blade, or upper unsupported end, of the spindle may be able to yield slightly
to the force exerted thereon by an unbalanced load. :
The central hole in the bolster bearing support 1. is shown as a cylindrical one,
for the greater part of its extent, and slightly larger than the diameter of the spindle,
although it is not in all cases desirable to adhere to this exact construction.
It is preferable to form near the upper part of the bolster bearing an oil retaining

page_text: groove 17. to prevent oil in considerable quantities from passing over the top of the
bolster 1. when the spindle is being used.
I have found that a spindle of the kind described runs very well indeed at the usual
speeds at which such spindles are operated, and that it is perfectly practicable to
remove the step case for the purpose of cleansing it and removing the sediment
which is intentionally allowed to settle therein below the lower end of the spindle,
even when the spindle is in operation and spinning yarn.
I prefer to make the fit of the lower end of the bolster bearing support 1. with the
shoulder of the step case with which it is usually in contact so perfect that the joint
between them may easily be made impervious to oil by screwing up the step case
tightly, although a soft metallic or other suitable washer may sometimes be advan-
tageously inserted at this joint as an equivalent for such perfect fit.
The much desired and so called gyrating capacity of spindles is possessed by this
invention to a considerable degree, on account of the looseness of the fit of the spindle
in the step and bolster bearings and of the freedom of the step to move laterally to a
slight extent in all directions.
When an elastic substance supports the step as herein described the spindle runs
with very little jar indeed at the highest desirable speeds.
The form of the lower end of the spindle insures that the bolster bearing is properly
lubricated when there is sufficient oil in the interior of the bolster, the oil being
carriod upwards by the action upon it of centrifugal force.
Another great advantage of the spindle as illustrated is the cheapness of its con-
struction, and the ease with which all its parts are reached for the purposes of
examination and cleansing.
I do not desire to limit myself in the use of my invention in all cases to the
particular forms, of the various parts of the structure which are herein illustrated,
since such forms of some of the parts may in some cases be much changed without
departing from the invention, and especially I do not desire in all cases to support the
foot step 12. upon the bolster bearing support by means of the detachable step case
as illustrated since I am aware that the said step-case may be made an integral part
of the said bolster bearing support when it is desirable to do so.
I am also aware that in some cases, it may be desirable to make the combined
bolster bearing, and bolster bearing support in two or more piecos, in which caso it
may be done without departing from my invention.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what 1
claim is:-
1. The combination of a step case forming part of or adapted to be attached to or
detached from the base of a bolster bearing support of a vertical spindle, with a
footstep supported therein by a longitudinally elastic support (formed of discs or
washers of leather or other suitable material) and free to move laterally in all directions
with respect thereto and to revolve or partially revolve therein substantially as described
and for the purposes specified.
2. The combination of a step case forming part of or adapted to be attached to or
detached from the base of a bolster bearing support, of a vertical spindle, with a
footstep supported therein by a longitudinally elastic support (formed of discs or
washers of leather or other suitable material), and free to move laterally in all directions
with respect thereto and with a pin or locking device to prevent the same from
revolving or partially revolving therein.
3. The spinning device which consists of a bolster bearing support provided with a
bolster bearing formed integrally therewith, a spindle provided with a sleeve whirl,
the plane of whose band groove crosses the said bolster bearing, a detachable step case
attached to the lower end of the said bolster bearing support and a footstep supported
in the said step case and free to move laterally in all directions, and a longitudinally
elastic support for the said footstep formed of discs or washers of leather or other
suitable material substantially as described and for the purposes specified.

page_text: 4. The spinning device which consists of a bolster bearing support provided with a
bolster bearing formed integrally therewith, a spindle provided with a sleeve whirl,
the plane of whose band groove crosses the said bolster bearing, a detachable step case
attached to the lower end of the said bolster bearing support, and a footstep supported
in the said step case and free to move laterally in all directions and to revolve or
partially revolve therein and a longitudinally elastic support for the said footstep
