PROVISIONAL SPECIFICATION.
Improvements relating to the Spindle Bearings of Spinning, Roving,
and Twisting Frames.
I, ROBERT LAUGHLIN, of 322, Shankhill Road, Belfast, Ireland, Mechanic,
do hereby declare the nature of this invention to be as follows:-
-
This invention relates to an improved method of applying necks and steps
to above frames. At the present time it is desirable that as much labour as
possible should be saved, for this purpose I adopt a novel system of applying
necks and steps. Heretofore the custom has been to drive them into their
position very tight, which entailed a great deal of labour afterwards in freeing
them by rhyming.
Process of fixing necks and adjusting of steps. The system I adopt is to make
the necks and steps with flat heads, with two small screws in each, to fasten
them to the rail, thereby leaving them quite free, as they are neither pressed
by tight driving nor grub screws as at present used.
For the adjustment of the spindle to make same lineable, I bore and tap the
step and apply an adjusting screw, so that when the spindle wears down out of
line it can be brought lineable by this adjusting screw, and very little expense
compared with the old custom, when spindles got out of line the old steps had
to be replaced by new ones which caused considerable delay and loss of the work
of machine.
These necks and steps can be applied to the present make of rails, but in new
machines I would make a hollow or grooved rail and with the flat instead of
saucer top, the oil can flow from one end of the rail to the other and oil each
spindle, and not as at present, when each has to be oiled separately.

Improvements relating to the Spindle Bearings of Spinning, Roving,
and Twisting Frames.
I, ROBERT LAUGHLIN, of 322, Shankhill Road, Belfast, Mechanic,
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 follow-
ing statement; -
This invention relates to what are known as neck and step bearings for the
spindles of spinning, roving, and twisting frames.
Heretofore it has been customary to drive the necks or steps into position in
the frames; a method of procedure which entails a great deal of labour especially

page_text: should it be desired at any time to withdraw them from the frames for the pur-
pose of repairs, renewals, or such like.
With my improved form of neck and step bearings and method of fitting
Bame into position in the frame a great deal of time is saved both in inserting
and withdrawing from the frame.
And in order that my said invention may be properly understood I have here-
unto appended an explanatory sheet of drawings, whereon,
Fig. 1 is a vertical section of the improved neck and step bearings as applied
to a spinning, roving, or twisting frame.
Fig. 2 is a plan view of same.
Fig. 3 is a slightly modified construction of the arrangement shown at Fig. 1;
whilst Fig. 4 is a plan view thereof.
In carrying out my invention I make the neck a and step b with a flat head c
having an annular casing or projecting rim d for the purpose of containing
any suitable lubricant for lubricating the spindle h (indicated in dotted lines).
The neck a and step b are secured in the rails ef of the spinning, roving, or
twisting frame by means of a screw, or screws g g¹, inserted through the flat
head c.
To enable the spindle h to be properly adjusted in the neck and step when
its lower end becomes worn, the step b is bored and tapped for the insertion of
an adjusting screw 2. The inner end of this adjusting screw is so shaped that
it forms a bearing for the lower end of the spindle h. By inserting a pin or
the like in the hole in the adjusting screw, the latter may be screwed upwards
so as to adapt it to the lower end of the spindle h and thereby retain same in a
proper working position. The jam nut serves to lock the adjusting screw in
the desired position. With this construction of step, spindles can be readily
kept in line and at very little expense as compared with the old method which
necessitated, when spindles get out of line, replacing the old steps by new ones
thereby causing considerable delay and loss.
In order to economise metal and enable the neck a to be more readily with-
drawn from the rail e it may, if desired, be recessed or grooved at k as shown in
Fig. 1.
The necks and steps, as above described, can be readily applied to the rails of
frames as presently constructed but in new machines I prefer to adopt the con-
struction shown at Figs. 3 and 4 of the drawings. With this construction the
rails e, f, are made with a hollow or groove l, m, into which fit the necks a and
steps which are preferably secured in position, as before, by means of
screws g, g. By making the rails e, f, as described the annular casing or
projecting rim d for lubricating purposes on the neck and step as shown at Fig. 1
is dispensed with and the oil or other lubricant when placed in the grooves l, m
readily flows from end to end thereof thereby lubricating all the spindles
simultaneously.
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 consider novel and desire to claim is:.
Neck and step bearings for the spindles of spinning, roving and twisting
frames constructed and fitted substantially as hereinbefore described and as
shown in the Figs. 1 to 4 of the drawings annexed.
