Improvements in and connected with Spindles for Spinning and
Twisting.
We, JOHN FRASER, PATRICK FRASER, and NORMAN FRASER, all of Westburn
Foundry, Arbroath, in the County of Forfar, North Britain, Engineers, do hereby
declare the nature of this invention to be as follows, that is to say:-
Our said invention has for its object to improve and simplify the construction
or arrangement of spinning or twisting spindles and their bearings and holders.
In carrying out our invention the spindles used are plain, with square or un-
pointed bottom ends; and each is held in a bottom and an upper tubular bearing
which is preferably of castiron, and is made with a recess for oil at the upper end.
Each bearing tube is made externally with a slightly projecting convex belt at
about its middle, and this belt fits in a holding socket, its convex form allowing
the bearing tube with its spindle to assume the best position when spinning. The
bottom, bearing tube is closed at its lower end, and a hard steel ball is placed
in it for the spindle to rest on as on a footstep bearing, the ball allowing free access
of the lubricant to the lower end of the spindle. The upper bearing tube has its
lower end dipping into lubricant in a cup formed in the top of the wharve; and
suits are formed in the lower end of the tube to give free access to the lubricant.
The lower and upper holding sockets for the bearing tubes of each spindle are
formed in a casting which may be made with sockets for one or more spindles.
The sockets are made with openings at their sides for conveniently inserting or
withdrawing the spindles, screws being used to draw together the sides of the
socket and grip the bearing tubes. The casting is made with fitting strips to
bear against the rail of the machine, and is fixed to the rail by a pair of bolts the
holes for which are made keylike or elongated to allow of easy removal. The rail
is, preferably a steel piece of channel section, but it may be of castiron as in
ordinary machines, and the holding sockets may be cast on it.
Instead of the lower bearing being as hereinbefore described it may be con-
structed in the ordinary way; and in some cases the upper and lower bearings
may be attached to upper and lower trame rails.

page_text: declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement, that is to say:-
Our said invention has for its object to improve and simplify the construction
or arrangement of spinning or twisting spindles and their bearings and holders.
And in order that our said invention and the manner of performing the same
may be properly understood, we hereunto append a sheet of explanatory drawings
to be hereinafter referred to in describing our improvements.
In the accompanying drawings Figure, 1, is a front elevation Figure, 2, a
horizontal section and Figure, 3, a vertical section of one modification of our
improvements. Figures, 4, 5, and 6, are respectively views, similar to Figures, 1, 2,
and 3, of a second modification. Figure, 7, is a horizontal section of a third
modification. In these drawings the same reference letters and numerals are used
to mark the same or like parts wherever they are repeated.
In carrying out the invention according to the first modification, each spindle, A,
is held in bottom and upper tubular bearings, B, C, made preferably of castiron
and formed with recesses, B 1, and C1, for oil at their upper ends. The spindles
used are plain with square or un-pointed bottom ends as shown in Figure, 3. The
bearing tubes, B, C, are formed externally with slightly projecting convex
belts, B2, C2, which fit into holding sockets, D, E, the convex form of the belts
allowing the bearing tubes with the spindle to assume the best position when
spinning. The bottom bearing tube, D, is closed at its lower end and a hard
steel ball, G, (Figure, 3) is placed in it for the square end of the spindle, A, to
rest on as on a footstep bearing, the ball allowing free access of the lubricant to
the lower end of the spindle, a groove, G1, being formed in the tube to lead the
lubricant from the recess, B1, to the footstep bearing. The upper bearing tube, C,
has its lower end dipping into lubricant in a cup, H, formed in the top of the
wharve, H 1, fixed to the spindle, A, and slits, H2, are formed in the lower end of
the tube to give free access to the lubricant. The lower end of the wharve, H 1.
is formed to act as a protecting cover for the upper end of the bearing tube, B.
The bottom bearing tube, B, can be adjusted vertically by an adjusting screw, J,
working in the holding socket piece, D), and acting against a flat lug, J1, on
the tube, the lug being arranged to bear against a stop, J 2, on the socket piece so
as to facilitate the setting of the tube, and prevent it turning round after being
set.
The lower and upper holding sockets, 1), E, for the bearing tubes, B, C, are
formed in a casting or bracket, K, made with sockets for one spindle, but it might
be made as hereinafter described with sockets for two or more spindles. The
sockets, D, E, are made with openings, D1, E1, at their sides for conveniently
inserting or withdrawing the spindle, and screws, E2, E3, engaging in pro-
jecting flanges, E4, E5, on the sockets, bind or draw together the sides of the
sockets, and thereby hold the bearing tubes firmly in position. The bracket, K,
is made with fitting strips to bear against the rail, L, of the machine, and is fixed
to the rail by screw bolts, L 1, engaging preferably in comparatively long checked
or rebated parts, K1, in the bracket to allow of easy removal. The bracket, K,
is not screwed quite tight up to the rail, L, but rests normally as shown on the
bolts, L1, by the shoulders formed at the upper ends of the checked parts, K 1,
this arrangement permitting the spindle to lift, in case of any emergency arising,
where such movement would be desirable. The bolts, L1, may however_be
arranged to engage in key like or elongated holes, instead of the checked parts, K 1.
The rail, L, is preferably a steel piece of channel section; but it may be of castiron
as in ordinary machines, and the holding sockets may be cast on it.
Instead of the lower bearing, B, being as hereinbefore described it may be con-
structed in the ordinary way; and in some cases the upper and lower bearings, C, B,
may be attached to upper and lower frame rails.
According to the second modification of our improvements shown in Figures, 4, 5,
and 6, the bracket, K, is made with sockets for two spindles and it is fixed to

page_text: the rail by upper and lower bolts, M, N, having extended parts to receive upper
and lower clip pieces, M2, N2. The clip pieces by means of thumb
screws, M3, N3, working on the extended parts, are pressed against the bearing
tubes, B, C, and thereby hold them firmly in position in their sockets.
In a third modification shown in Figure, 7, our improvements are shown as
applied to existing machines. The holding sockets, D, (E) are formed in a casting
or bracket piece, P, which is fixed to the frame rail, L, the bracket being shaped
at the socket parts to fit semi-circular seats, Q, or seats of other suitable shape,
formed in the rail, the bearing tubes being held in their sockets by clip pieces as
in the former modification.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:-
1. The construction, combination, and arrangement of parts constituting our
improvements in and connected with spindles for spinning and twisting, sub-
stantially as hereinbefore described with reference to the accompanying drawings.
2. In and connected with spindles for spinning and twisting, a spindle held
in bottom and upper bearing tubes, the lower end of the spindle resting on a
ball bearing in the bottom tube, both tubes having upper oil recesses, the lower
end of the upper tube having slits, and dipping into an oil recess in the spindle
wharve the lower end of which is made to form a cover for the upper end of the
bottom tube, both bearing tubes being formed with projecting convex belts to
fit adjustably in sockets open at the sides and formed in a bracket arranged
with sockets for one or more spindles and adjustably fixed or formed on the
spinning frame rail or rails, each bearing tube being held in its socket by means
of a screw bolt engaging in flanged or projecting parts of the socket, or by a clip
piece engaging on a bolt and pressed against the tube by a nut, substantially as
herein before described with reference to the accompanying drawings.
3. In and connected with spindles for spinning and twisting, the combination
of an upper bearing tube as described in the previous claim, with a lower bearing
as ordinarily constructed, substantially as hereinbefore described.
