Improvements in and Connected with Wharves for Spinning Spindles..
We, THOMAS HALL, gentleman and FRANCIS A. HALL, gentleman both of
Lawrence, in the County of Essex, and State of Massachusetts, United States
of America, 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 our invention relates to an improvement in spinning-machine whirls; and
our object is to so improve these whirls that the flanges are not liable to be
fractured or otherwise injured under ordinary usage.
We attain this object by the
means illustrated in the annexed drawings in which
Fig. 1. is an enlarged diametrical section of the lower part of a spindle, shewing
the peculiar construction of our improved whirl. Fig. 2. is a side view of a spindle
having our improved compound whirl applied to it. Fig. 3. is a diametrical section
shewing the modification of Figs. 1 and 2 hereinafter explained.
Similar letters refer to like parts in all the views.
The letter A designates a tubular spindle having an annular flange, a, and
provided with a stud, e, the latter to key the spool to the spindle, so that the spool
will rotate with the latter in the usual well-known manner. Below the flange a, and
integral with the spindle-tube A, is a tapered enlargement or boss, A', shown clearly
in Fig. 1. of the annexed drawings. On this boss we rigidly secure our improved
whirl B. This whirl has before our invention been made integral and of cast metal.
In practice we find that the upper flange when the whirl is so cast is frequently
broken by reason of the fragility of the cast metal. To obviate this objection, we
construct the lower or base flange or washer, c¹, of the whirl and the body d entire,
and preferably of cast iron, and we make the top flange or washer, e, independent
thereof, and employ wrought metal, or other suitable material less fragile than the
base c¹ and body & to form the said flange or washer. We first drive the metal
washer or flange e on the boss A¹ of the tube A. We then drive the boss A¹
of the tube A into the central aperture through the body d and base-flange c¹ of
the whirl B.

page_text: It is obvious that both flanges e and c¹ of the whirl B may be made of a
comparatively tough metal or other suitable material, and the body d of a less fragile
metal that is to say, when both flanges e and c¹ are made of a less fragile metal
than the body portion d the lower Hange, c¹, may be held tightly upon the reduced
end of the body d by friction or in any other suitable manner, and a portion, C2,
driven upon the tapered boss A', as shewn in Fig. 3.
It will be observed from the foregoing that we produce a spinning-whirl having
an independent flange which is not adjustable and which is not liable to be broken;
also, that we produce a whirl, one or both flanges of which may be readily replaced,
if necessary. Furthermore, it will be seen that by our invention the old and well-
known whirls having broken flanges can be utilised by cutting off the useless flanges
and substituting more perfect and more endurable ones.
Having now particularly described and ascertained the nature of our said inven-
tion, we declare that what we claim is :-
1. A spinning-machine whirl having a flange or washer formed separate from the
body d, both being adapted to be applied to a tubular spindle, as specified.
2. The combination, with the tubular spindle, of a whirl composed of a body, d,
and flanges formed separate therefrom and united upon the boss of said spindle, as
specified.
3. The herein-described spinning-whirl having a body and a flange formed of
cast metal in one piece, and a flange formed of wrought metal, substantially as
described.
4. The combination, with the tubular spindle having a flange, a, and a boss, A¹,
of a whirl composed of a cast metal body and flange and a wrought-metal flange, e,
substantially as described.
