PROVISIONAL SPECIFICATION.
Improvements in Collars for Spindles of Spinning and Twisting
Frames.
I JOHN PATON junior of Chapel Works, Montrose, North Britain Flax Spinner, do
hereby declare the nature of this invention to be as follows:-
The object of this invention is to provide a more efficient means for lubricating the
spindles of spinning and twisting machinery than that at present in use.
Instead of applying the lubricant directly to the bearing surface of the collar
I provide in the collar a lubricant chamber from which the lubricant will escape as it
is required and lubricate the spindle supported by the collar.
My improved lubricating collar retains externally the ordinary form and it is carried
as usual adjustably in the rail or bar.
This collar is bored out to receive an externally ribbed tube which forms the
bearing surface for the spindle and fitting tightly in place forms a receptacle between
it and its seat for the lubricant. This receptacle is closed at top by a cover and at
bottom by a flange carried by the internal tube.
This tube which forms the bearing surface is pierced with holes to allow of the
lubricant escaping from the ebamber and spreading over the bearing surface of
the tube.
By preferance I propose to employ a viscid form of lubricant which under the
friction heat of the spindle will flow slowly from the chamber and maintain for a
comparatively long period an effective lubrication of the collar and spindle.
This it will be understood provides against the loss of lubricant at present experienced
in spinning and twisting machinery where the oil runs down the spindle leaving the
contact surfaces comparatively dry.
The advantages consequent on the use of this invention are that the spindles run
more steadily are more easily driven and the speed is much more regular because
there is less liability to slipping of the driving band and thus a uniform twist will be
imparted to the thread.
Moreover an economy in the wear of the spindles and collars is effected by reason
of the lubrication being better maintained than heretofore.

COMPLETE SPECIFICATION.
Improvements in Collars for Spindles of Spinning and Twisting
Frames.
1 JOHN PATON junior of Chapel Works, Montrose, North Britain, Flax Spinner,
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:-
The object of this invention is to provide a more efficient means for lubricating the
spindles of spinning and twisting machinery than that at present in use.
Instead of applying the lubricant directly to the bearing surface of the collar,
I provide in the collar a lubricant chamber from which the lubricant will escape as it
is required, and lubricate the spindle supported by the collar.
My improved lubricating collar retains externally the ordinary form, and it is
carried as usual adjustably in the rail or bar of the spinning or twisting
frame.

page_text: In the accompanying drawing
Fig. 1 is a sectional elevation of my improved lubricating collar fitted to receive a
spindle with a conical neck, and
Fig. 2 is a sectional plan of the same.
Fig. 3 shews in sectional elevation a modification of the lubricating collar formed to
receive a spindle with a parallel or cylindrical neck.
A, Figs. 1 and 3 is the rail or spindle bar, into which the collar B is adjustably
fitted in the usual manner. This collar consists of a cylindrical tube into which is
tightly fitted a conical bush C, made of gun metal or equivalent material. The bush C
is formed with external longitudinal ribs, and it also carries a flange at foot for
closing the space between the bush and the collar, which space constitutes a chamber
for the reception of the lubricant.
The bush is pierced with holes to permit of the lubricant reaching the spindle D,
which turns freely in the bush C.
ติ
The lubricant chamber is closed at top by a lid E, which is removable to allow of
the renewal of the lubricant which, when poured into one division of the lubricant
space, will flow over into the adjacent spaces, and thus fill the chamber.
As the temperature of the pierced bearing surface of the bush is raised by reason of
the rapid rotation of the spindle, an even flow of the lubricant to the neck of the
spindle will take place
By preference I employ a viscid form of lubricant, which, under the friction heat
of the spindle, will become limped, and flowing slowly from the chamber, will maintain,
for a comparatively long period, an effective lubrication of the bush and spindle.
This construction of collar, it will be understood, provides against the loss of
lubricant at present experienced in spinning and twisting machinery, where the oil
runs down the spindle, leaving the contact surfaces comparatively dry.
The advantages consequent on the use of this invention are, that the spindles run
more steadily, are more easily driven, and the speed is much more regular, because
there is less liability to slipping of the driving band, and thus a uniform twist will
be imparted to the thread.
Moreover, an economy in the wear of the spindles and collars is effected, by reason
of the lubrication being better maintained than heretofore.
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 :-
Constructing collars for spinning and twisting frames as above described, in which
a lubricant chamber is provided for supplying, through holes made in the bush or
bearing surface of the collar, lubricant to the neck of the spindle working therein, as
and for the purpose above set forth.
