IMPROVE- MENTS IN THE BEARINGS OF SPINDLES FOR SPINNING AND DOUBLING AND THE MODE OF FASTENING THE SAME TO THE SPINDLE RAILS
Year: 1884

page_text: I THOMAS MANGNALL GRIBBIN Spindle and Flyer Maker of Manchester in the
County of Lancaster do hereby declare the nature of said invention for IMPROVE-
MENTS IN THE BEARINGS OF SPINDLES FOR SPINNING AND DOUBLING AND THE
MODE OF FASTENING THE SAME TO THE SPINDLE RAILS to be as follows:-
My improvements in the bearings of Spindles consists in making the top and
bottom bearings in two separate parts and in attaching them together in such a
manner as to make one complete fixing the whole being fastened to one Spindle
rail described as follows:-I make the footstep part with an annular flange forming
a shoulder to rest on the spindle rail, the bolster part is formed of a clamp ring
provided with an upright bracket arm holding the top bearing of the spindle in its
upper part. This clamp ring is made to fit the annular flange of the footstep and
is provided with a screw for fastening it to the flange the two bearings can thus be
easily separated and the Spindle taken out for the purpose of cleansing or repairing.
My improvement for fastening the bearings of spindles to the spindle rail consists
in placing a flannel washer between the flange of the bearing and the top of the
spindle rail and a spiral spring on the stem or shank of the bearing below the
spindle rail and between the fastening nut. The nut is screwed up thereby
compressing the spring until sufficient stability or firmness is given to the spindle
bearing; the nut is kept in that position by a collar fastened by a set screw below
the nut or by a second lock nut or the spring may be compressed as required and
held in position by means of the collar alone, by this means an elasticity is given
to the fixing of the spindle whereby higher speed may be attained.

County of Lancaster, do hereby declare the nature of said invention for IMPROVE-
MENTS IN THE BEARINGS OF SPINDLES FOR SPINNING AND DOUBLING AND THE
MODE OF FASTENING THE SAME TO THE SPINDLE RAILS and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement :—
My Improvements in the Bearings of Spindles consists in making the top and
bottom bearings in two separate parts and in attaching them together in such a
manner as to make one complete fixing the whole being fastened to one spindle
rail-In the accompanying sheet of drawings Fig. 1 represents an elevation of a
spindle with my improved arrangement of the top and bottom bearings. Fig. 2 is
a plan of the same, a is the footstep part or bottom bearing and is formed with an
annular flange b forming a shoulder to rest on the spindle rail c, The bolster or
top bearing part is formed of a clamp ring d provided with an upright bracket
arm e, forming or holding the top bearing of the spindle f in its upper part―The
clamp ring is made to fit the annular flange 6 of the footstep a, and is fastened to
it by a set screw g-The footstep may be fastened to the spindle rail c, by a set
screw through the side of the rail, or a nut at its lower end, as shewn in the
drawing, The top bearing can thus be easily separated from the bottom bearing
and the spindle taken out for the purpose of cleaning or repairing.
My Improvement for fastening the bearings of spindles to the spindle rail consists
in placing a flannel washer between the flange of the bearing and the top of the
spindle rail, and a spiral spring on the stem or shank of the bearing below the
spindle rail and between the fastening nut.-Fig. 3 of the accompanying drawing
shews this part of my invention, a is the spindle bearing, b is the flange of the
bearing, d is the flannel washer between the flange of the bearing and the spindle
rail c, g is the spiral spring, e is the nut for compressing or tightening the spring
to give sufficient stability to the spindle, f is a collar between the nut and the
spring which when the spring is sufficiently compressed is fastened with a set
screw thus acting as a lock nut or two nuts may be used or the collar itself without
the nuts. By this means an elasticity is given to the fixing of the spindle whereby
higher speed may be attained.
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
First The making of the top and bottom bearings of spindles in two separate
parts and attaching them to one spindle rail as described.
Second-The use of a flannel washer and a spiral spring as described either in
combination or separate, for fastening the bearings of spindles to the spindle rail.
