1 THOMAS KILVINGTON HATTERSLEY of Leeds in the County of York, Spindle and
Flyer Manufacturer, do hereby declare the nature of this invention to be as follows:-
The object of this invention is to facilitate the adjustment of spindles in their
bearings. It is chiefly applicable to the vertical spindles used in textile machinery,
for example, flyer spindles, which have a step and collar bearing, the spindle being
coned to fit the adjustable coned collar.
I will describe my invention in relation to the vertical spindles of spinning and
twisting machinery, but it will be obvious that my improvements may be readily
applied to the adjustment of other kinds of spindles, whether vertical or horizontal.
Great difficulty has hitherto been experienced in adjusting the spindle bearings of
dry spinning machinery, and hence the tendency to run such machinery while the
spindles are loose, to the great detriment of the wearing parts.
Instead of, as heretofore, relying on the adjustment of the collar bearings in their
rails by taps from a hammer, a tedious and uncertain means of adjustment, I now
propose to cut, in the periphery of the collar bearing, a helical groove to receive the
rounded end of a stud, which projects through the rail into the seat for the bearing,
and fits the helical groove which extends from end to end of the collar bearing.
This stud is fitted into a hole drilled through the face of the spindle rail to the
bearing socket, and in rear of the stud, the bole is tapped to receive a binding screw,
which fits the tapped hole in the rail, and bears against the rear end of the stud, with
the object of forcing it into the helical groove and fixing the bearing firmly in its
socket..
The helical groove is made to provide for the vertical adjustment of the bearing,
which is coned internally to fit the coned portion of the spindle.
Tlie bearing is flattened at its opposite sides to receive a key for turning it. When
the screw is slackened, the bearing is free to turn under the action of a key, whereby
it may be lowered in its rail to fit the coned portion of the spindle.
For the step bearings of the flyer spindles, the like provision is adopted, the helical
groove cut in the exterior of the bearing providing for its vertical adjustment by
imparting an axial motion thereto.
It will be obvious that my invention may be readily applied to the bearings at
present in use in textile machinery generally.

page_text: I THOMAS KILVINGTON HATTERSLEY, of Leeds, in the County of York, Spindle
and Flyer Manufacturer 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 this invention is to facilitate the adjustment of coned spindles in their
bearings, the invention being specially applicable to the live spindles used in textilo
machinery, for example, flyer spindles which have a step and collar bearing, the
spindle being coned to fit the adjustable coned collar.
Great difficulty has hitherto been experienced in adjusting the spindle bearings of
dry spinning machinery, and hence the tendency to run such machinery while the
spindles are loose, to the great detriment of the wearing parts.
Instead of, as heretofore, relying on the adjustment of the collar bearings in their
rails by taps from a hammer, a tedious and uncertain means of adjustment, I now
adopt the arrangement shewn in the accompanying drawing:
Fig. 1 is a plan view of a portion of the top rail of a spinning frame, with my
invention applied thereto.
Fig. 2 is a front view of the same, and
Fig. 3 is a cross section of the rail, showing the adjustable bearing in place, and
the means for fixing it in the rail.
In these Figures, A is the rail, B a portion of a coned spindle, fitting a coned
collar bearing C. Around the collar bearing C a helical groove is cut to receive
the rounded end of a stud c, which projects through the rail into the seat for the
bearing, and fits the helical groove which extends nearly from end to end of the
collar bearing.
This stud is fitted into a hole drilled through the face of the spindle rail to the
bearing socket, and in rear of the stud, the hole is tapped to receive a binding screw c¹
which fits the tapped hole in the rail, and bears against the rear end of the stud, with
the object of forcing it into the helical groove, and fixing the bearing firmly in its
socket..
The helical groove is made to provide for the vertical adjustment of the bearing,
which is coned internally, as usual, to fit the coned portion of the spindle.
The top end of the bearing is squared to receive a key for turning it. When the
binding screw c¹ is slackened, the bearing is free to turn under the action of a key,
whereby it may be lowered from time to time in its rail, to fit the coned portion of
the spindle as the contact surfaces wear away.
The increased facility thus afforded for adjusting the collar bearings of spindles,
will be obvious, as all that is required from the attendant, is to slacken the binding
screw, and impart, by the key or spanner, a slight axial motion to the bearing, to
bring it into closer contact with the coned spindle, which position is then to be

page_text: secured by tightening up the binding screw, and thereby forcing the stud c into close
contact with the helical groove.
For the step bearings of the flyer spindles, the like provision for vertical adjust-
ment to that described with reference to collar bearings is adopted, the helical groove
cut in the exterior of the bearing for the reception of the stud e providing for the
vertical adjustment of the step bearing on axial motion being imparted thereto.
I would remark that means have been proposed for facilitating the adjustment of
coned bearings in their rails through the action of screw threads; thus, the periphery
of the bearing has been threaded, and the rail tapped, to receive the screw thread.
Again, the ends of the bearing have been threaded to receive adjusting nuts, which,
when tightened up, bore against the opposite faces of the rail, and imparted, when
desired, an endway adjustment to the bearing.
The obvious disadvantages, however, of these plans, left the old mode of adjust-
ment in full force, notwithstanding the trouble which its use involved.
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 construction of adjustable coned collar and step bearings for live spindles as
described, which admit of being turned in their supports for the purpose of longi-
tudinal adjustment, such adjustment being effected by the aid of a stationary guiding
and locking stud as above set forth.
