PROVISIONAL SPECIFICATION.
Improvements Connected with Mounting the Circles of "Noble's"
and other Combing Machines.
We, CHARLES HOYLE, and JAMES RAMSDEN HOYLE, both of Greengate, Keighley,
in the County of York, Machine Makers, do hereby declare the nature of this invention
to be as follows:-
This invention has for its object, the minimising the danger of damage to which the
comb pins or teeth of the circles are liable by the inaccurate rotation of the latter,
consequent on the retaining or bearing flange of the rack plate becoming slack in its
path, by constant rotation and thereby continued wearing of the rack and steam chest
or other plate flange surfaces; by which the rack plate and therefore the comb circle
is allowed to rotate otherwise than in a true and accurate circle.
In order to compensate for the wearing of the above named surfaces, and retain the
necessary accurate rotation of the comb circles, I accomplish the same by forming the
bearing surfaces of the flanges at right angles to the respective plates, or conically
inclined thereto; and combining with the steam chest or other suitable plate, an
additional ring made adjustable, or a series of curved plates somewhat wedge shaped
in their vertical section; each plate being fit into a recess and adjustable, so that any
wear of either flange may be compensated by regulating the additional ring or curved
plates; thereby retaining the rack and comb in their true, position, and securing
accuracy of rotation so essential with fine pitched comb circles.

COMPLETE SPECIFICATION.
Improvements Connected with Mounting the Circles of Noble's
and other Combing Machines.
We, CHARLES HOYLE, and JAMES RAMSDEN HOYLE, both of Greengate, Keighley,,
in the County of York, Machine Makers, 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 has for its object, the provision of means for minimising the liability
of damage to the comb pins or teeth. of the circles by the inaccurate rotation of the
latter, consequent on the retaining flange on the rack plate-becoming slack in its path
by the constant friction and rotation, and thereby continual wearing of the rack and
steam chest or other plate flange surfaces; by which the rack plate and therefore the
comb circle is allowed to rotate otherwise than in a true and accurate circle: and
consists in combining with the steam chest an additional ring or a series of curved
plates somewhat wedge shaped in their vertical section made to fit a corresponding
inclined service; and being made adjustable, any wearing of the rubbing surfaces
may be compensated by regulating the additional ring or curved plates, thereby
retaining the rack and comb circles in their true circular path.
In describing our invention more in detail reference is made to the accompanying
drawings, in which,
Fig. 1. represents such portions of the plan of a large comb circle as are required
to show our invention which is added thereto, part of the rack plate supporting the
comb circle being cut away so as to more clearly show the steam chest plate.
Fig. 2. is a section of the same through lines a. b.

page_text: Fig. 3. an enlarged sectional detail through the steam chest plate, rack circle and
adjusting curved plate, and
Fig. 4. is a front view of the same.
In carrying out our invention, we by preference cut in the steam chest and
plate A, a series of recesses as at B. at an acute angle with the top face of the
steam chest, and mount in each recess a curved plate D. somewhat wedge shaped
and cut to such an angle as to fit the inclined surface before referred to, and the
turned face of the rack flange at E.
Each curved plate D. is formed with a flange at the bottom or wide part, and
is kept in its position against the steam chest and in working contact with the
turned face of rack flange E. by the set screws passing through brackets F. secured
to the underside of the steam chest plate.
The outer screws G. G. are threaded for the entire length, and engage with threads
cut through the bracket F. so that by regulating there screws, the respective wedge
shaped curved plates D. may be raised or lowered as desired, one side being against
the steam chest and the other in working contact with the rack circle flange for
keeping the latter and the comb circle in their true circular path: the other screw H.
in the centre, passes freely through the bracket F. but is threaded to engage with the
flange at the bottom of the curved plate, so that on the respective screws G. G.
being regulated to support the curved plates D. at the desired height for retaining
the rack circle in a true path, the centre screw of each bracket is tightened, thereby
locking the curved plates in their required position until they require readjustment
to compensate for the wearing away of the surfaces and in order to lubricate the
wearing surface of the curved plates D. and the turned surface of rack flange working
in contact therewith, we form a channel in each carved plate D. and connect therewith
a pipe K. having a cup at the top through which lubricating material is supplied
to the parts named.
It will be easily perceived by persons having mechanical knowledge that our object
may be accomplished by cutting the inner face or circumference of the steam chest
to the same or a similar angle as the recesses at B. and making the several curved
plates considerably longer, or in one entire ring, which may be supported by a
series of screws similar to G. and locked by intermediate screws H. arranged in the
manner as before described.
Having now particularly described and ascertained the nature of our invention
and in what manner the saine is to be performed, we declare that what we claim is :
1. In a combing machine the combination of a series of wedge shaped curved
plates D. with the steam chest and rack circle for the purpose described.
2. In a combing machine the combination of a series of wedge shaped curved
plates D. with the steam chest and rack circle and the adjusting screws H. substantially,
in the manner shown and described and for the purpose as hereinbefore set forth.
3. The hereinbefore described method of retaining the rack circle in its true
circular path by a series of curved plates or by an entire ring made taper to fit a
recess or space between the steam chest and a flange on the rack circle, all arranged
substantially in the manner described.
