PROVISIONAL SPECIFICATION.
Improvements in or relating to the Bearings of Spindles of Spinning
and like Machines.
I, JAMES BARBOUR, of the Firm of Combe, Barbour, and Combe, Limited, of
Falls Foundry, Belfast, Ireland, Machinist, do hereby declare the nature of this
invention to be as follows:-
-
This invention relates to rail bearings of spindles of said machines, and the
improvements hereinafter described effect considerable saving in the cost and
labour of fitting, and also ensure accuracy of adjustment of the relative parts
not attainable under the old system of fitting.
In the boring of holes for the long collars in the top rail and the holes
for the footsteps in the lower rail, accuracy of relative position of the
upper and lower holes is not attainable by reason of the holes not being
all bored true, or by reason of the fitting of the rail throwing the
holes out of vertical line, hence the practice of reaming out the hole in
the long collar so as to admit, through faulty fitting, the major part of the hole in
the long collar being made linable with the footstep on the bottom rail.
We have designed and constructed a long collar so as when in position in the
hole of the top rail and the spindle is in position in the long collar, the
long collar and spindle automatically assume a vertical or true plumb line in
relation to the footstep on the lower rail, the said collar is then secured or fixed
in such position by set screw as ordinary.
The long collar is bored internally for the spindle in the usual way, but its
outer portion is of two different diameters, one portion practically fitting the hole
in the top rail, the other portion of said collar being of less diameter than the
hole, such for example tapering in two directions or two cones in opposite
directions. So likewise the oil cup formed on the head of the long collar must
not lie flat on the top rail, but is made convex to the upper surface of the rail
that when the spindle is passed through the long collar and into the footstep
on the bottom rail, the long collar will roll or move on its contact part with the
hole in the top rail, and the convex head of the long collar will admit of the
required movement, and the whole are then in true relative position, whereon
the long collar will by the set or fixing screw be made secure in its corrected
position.

Improvements in or relating to the Bearings of Spindles of Spinning
and like Machines.
I, JAMES BARBOUR, of the Firm of Combe, Barbour, and Combe, Limited, of
Falls Foundry, Belfast, Ireland, Machinist, 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 improvements in the manufacture of the rail bearings
for the spindles of spinning and like machines the object being to facilitate the
fitting of the bearings and also to facilitate and ensure accuracy of adjustment
of the relative parts not easily attainable under the old system of fitting. The
invention consists in the use of a long collar and oil cup so constructed that the
former automatically adjusts itself to the spindle and falls into position in its
carrying rail where it is held by means of a set screw.
Such being the nature and object of the said invention the following is a
complete description of same, reference being had to the annexed drawings
in which.
Fig. 1 is a sectional side elevation of a spindle and rail fitted with the
improved bearing.
Fig. 2 is a sectional elevation of the improved bearing detached.
Heretofore in the boring of the holes 1 of the bearings or long collars 2 in
the top rail 3 and the holes 4 for the footsteps 5 in the bottom rail 6 accuracy of
position of the holes has not often been attained owing to all the holes not being
bored truly or through the rails 3, 6 not being accurately adjusted in relation
to one another when fitted to the machine, thus the holes 1, 4 were thrown out
of a vertical line. It has been sought to remedy the defect by reaming or
reboring the hole in the long collar after the latter has been placed in position in
its top rail, the idea being to fix the long collar in position, and then to ream out
the internal bore more or less so as to bring the greater part of it linable with
the footstep 5 in the bottom rail 6.
According to this invention I employ a long collar 2 with an oil cup 7 forming
a part of it and the under side of such oil cup 7 is convex or bevelled for the
purpose hereinafter described. The outside of the long collar 2 is made conical
for two portions 8, 9 of its length, the bases or wide parts of the cones 8, 9 being
towards each other with a narrow intervening space 10 between, of cylindrical
form, and diameter corresponding in size to the hole in the rail 3. The long
collar 2 is bored internally for the spindle 11 in the usual manner and it is inserted
into the top rail 3 until the oil cup 7 rests on the top rail of the 3 and the oil
eup 7 not being flat on the underside, and the outside of the collar 2 being of the
shape described the long collar 2 will rock or roll in the rail or move until it
adjusts itself to the spindle 11 and to the footstep 5 on the lower rail 6 whereon
the long collar is fixed in position in the rail 3 by means of the set screw 12.
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―
The improved method of and means employed for automatically adjusting the

page_text: long collars or top rail bearings of spindles to the spindles and their footsteps as
and for the purpose herein described and substantially as illustrated by the
accompanying drawings.
