PROVISIONAL SPECIFICATION.
Improvements in the Footsteps of Spindles used in Spinning,
Twisting, Doubling, and similar Frames.
I, WILLIAM FLECK REYNOLDS of Linfield Foundry, Grosvenor Street Belfast,
in the County of Antrim Ireland, Engineer do hereby declare the nature of this
invention to be as follows:-
As usually constructed & mounted the footsteps employed for spindles used in
spinning, twisting, doubling & similar frames have their heads hollowed out & a rim
or ledge left thereon so as to form a receptacle or cup for the lubricating oil. They
are protected from dust or waste by a cast or stamped metal cover which fits around
lower part of spindle, embracing at same time the foot step in which the spindle
revolves, in such a manner that it may be readily raised & replaced. The oil lying
in the cup of footstep having the whirling motion of spindle imparted to it is liable
to be thrown out & lost. The object of my invention is to obviate this waste of
lubricant & my mode of carrying it out is as follows.
I place in the oil cup of the footstep a short tube or ring of sheet or cast metal
wide enough in its bore to admit of the passage of lower part of the spindle through
it without contact, this ring or tube may be of cylindrical, conical or other suitable
form in section. I furnish the tube with a flange or base which fits into cup of foot-
step when I find it necessary to employ tubes of small diameter. At or near the
base or lower end of the tube I drill holes to admit of the free passage of the oil into
annular space formed around foot of spindle in oil cup or I notch or slit the base or
lower end of the tube in lieu of drilling for the same purpose. The ordinarily used
step cover may be removed in the usual way without disturbing the tube or ring.
It will be seen that only to the oil in the inner of the two chambers formed in
the footstep by the tube or ring placed therein can the whirling motion of the
spindle be communicated so that none of the oil can be thrown out or wasted from
this cause.

Improvements in the Footsteps of Spindles used in Spinning,

I WILLIAM FLECK REYNOLDS of Linfield Foundry, Grosvenor Street, Belfast,
in the County of Antrim, Ireland, Engineer, 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 :-
As usually constructed & mounted the footsteps employed for spindles use. in
spinning, twisting doubling & similar frames have their heads hollowed out & a rim
or ledge left thereon so as to form a receptacle or cup for the lubricating oil. They
are protected from dust or waste by a cast or stamped metal cover which fits around
lower part of spindle embracing at same time the footstep in which the spindle
revolves, in such a manner that it may be readily raised or replaced.
The oil lying
in the cup of footstep having the whirling motion of spindle imparted to it is liable
to be thrown out & lost.
The object of my invention is to obviate this waste of lubricant & my mode of
carrying it out is as follows.
I place in the oil cup of footstep a short tube or ring of sheet or cast metal wide

page_text: enough in its bore to admit of the passage of lower part of the spindle through it
without contact. This ring or tube may be of cylindrical, conical or other suitable
form in section. I furnish the tube with a flange or base which fits into cup of
footstep, when I find it necessary to employ tubes of small diameter. At or near the
base or lower end of the tube I drill holes to admit of the free passage of the oil
into annular space formed around foot of spindle in oil cup or I notch or slit the
base or lower end of the tube in lieu of drilling for the same purpose. The ordinarily
used step cover may be removed in the usual way without disturbing the tube or ring.
It will be seen that only to the oil in the inner of the two chambers formed in the
footstep by the tube or ring placed therein can the whirling motion of the spindle be
communicated so that none of the oil can be thrown out or wasted from this
cause.
On the accompanying sheet of drawings, C is the lower part of a spindle revolving
in footstep, a vertical section of which is shewn at B. D is a section of the
bottom or step rail of spinning or twisting frame, A is a vertical section of the
ring or tube placed in footstep, A¹ is an elevation, A² a representation of the base
or under side of same, E is a vertical section of a footstep having the ring or tube
turned out of the solid, the holes for admission of lubricant to spindle foot being
afterwards drilled at F as shewn.
Having now particularly described & ascertained the nature of my said Inven-
tion & in what manner the same is to be performed I declare that what I
claim is-
The use in spinning, twisting doubling & similar frames of footsteps for spindles
furnished with tubes or rings fitted in their oil cups or reservoirs for the purpose
bereinbefore set forth substantially as indicated by the accompanying drawings &
described, whether these tubes form part of the footsteps themselves, are loose in
them, or, attached to them by soldering, brazing or otherwise.
