Improvements in Spinning Spindles.
A communication by HENRY D. KLOTS, of 165, Broadway, New York, in the
County and State of New York, United States of America, Gentleman.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for
Foreign Patent Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street,
Manchester, both in the County of Lancaster, and 323, High Holborn, in the
County of Middlesex, Civil 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 :-
This invention relates to spinning spindles wherein the bobbin holding spindle-
blade is allowed to yield laterally to accommodate itself to an unbalanced load and
thereby prevent vibration and its resulting disadvantages.
This improvement consists primarily in mounting a spindle-blade constituted with
a spring intermediate the bobbin-holding and bolster-bearing portions thereof in a
bearing which is yieldingly connected to a spindle rail, whereby the flexibility of
the said spring and the yielding connection of the said bearing will conspire in a
novel manner to take up and remove both the local and bodily vibration of the
spindle, due to an unbalanced load. This improvement also consists of a rigidly
combined bolster and step-bearing for the spindle yieldingly connected to the
spindle-rail by means of a universal joint such that the said combined bearing can
swing on a fixed centre, in exact consonance with the tendency due to an unbalanced
load.
In order that the invention may be clearly ascertained, the manner in which the
same is carried into effect will be first described in detail, and then its novel
features pointed out in the claims.
Reference is to be had to the accompanying drawing forming part of this
Specification, in which―
Figure 1 is a sectional elevation of a spinning spindle embodying the invention;
Figure 2 is a sectional plan view of the same on the line 2-2, Figure 1.
Corresponding parts are designated by like letters of reference in both figures.
A, designates the spindle-rail, B an attachable portion thereof, F the spindle-
blade, and C and C the bolster and step-bearings respectively on which the lower
portion of the spindle-blade F is mounted.
The spindle-blade is constituted above the bolster-bearing C¹ and below the
bobbin-holding portion F' with a spring H which may be rigidly attached to the
ends of said bolster-bearing and bobbin-holding portions of the blade, or formed
integrally therewith by reducing the diameter of the blade to one-eighth or three-
sixteenths of an inch according to the previously determined temper of the metal,
so that above the bolster-bearing C¹, the spindle-blade, with the whirl G, is free to
play laterally in all directions against the resiliency of the spring H.
The bolster-bearing C' is connected yieldingly to the spindle-rail A, and it is
preferred to construct such yielding connection as follows-
The bolster and step-bearings C1 and C2 are rigidly combined in the form of a
bearing-tube C which is mounted on the rail A. by means of a universal joint D,,
such that every joint of the spindle-bearing tube C will be allowed a movement
only in arcs of circles described about the fixed centre of said universal joint D.
The bearing-tube is here shown upheld and its lateral deviation resisted by
several radially arranged springs E bearing laterally against the tube.
In place of the pivot form of universal joint here shown, a ball-and-socket joint
or ordinary gymbals are sometimes used with equal advantage.

page_text: The spring H accommodates and takes up what is termed the "local," that is,
waves of vibration in the spindle due to an unbalanced load, and arranges or
transforms the same into a resultant "bodily" vibration, which is communicated to
the spindle-bearing, whence it is finally and fully taken up by the yielding
connection of the spindle-bearing with the rail A.
The best results are obtained with the rigidly combined bolster and step-bearing
and a yielding connection in the form of the fixed-centre universal joint described,
but good results are obtainable with universally yielding connections of various
other forms, as well as with a bolster-bearing yielding independently of the
step-bearing.
Continued use of this self-springing spindle in combination with the yieldingly
connected spindle-bearing, has demonstrated that it can be run at speeds three
times as great as can ordinarily be employed without appreciable vibration.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me
by my foreign correspondent, I declare that what I claim is―
1. The combination of a yieldingly mounted spindle-bearing and a spindle-blade
constituted with a spring intermediate its bobbin-holding and bearing portions,
substantially as described.
2. The combination of a rigidly combined holster and step-bearing, its universal
joint and a spindle-blade constituted with a spring intermediate its bobbin-holding
and bolster-bearing portions, substantially as described.
3. In a spinning spindle, a rigidly combined bolster and step-bearing for the
spindle-blade mounted on a fixed-centre universal joint, substantially as described.
