Improvements Connected with the Mounting of the Circles of
Combing Machines.
We, THOMAS BASTOW, of Wapping Shed, Bradford, in the County of York, Wool-
Comber and THOMAS HENRY SHAW, of the same place, Manager, do hereby declare
the nature of this invention and in what manner the same is to he performed, to
be particularly described and ascertained in and by the following statement :-
The object of this invention is the provision of means whereby the comb circles
may be retained in a true circular path by certain combinations arranged in such a
manner that the invention may be applied to old machines constructed in the usual
manner as hitherto also in conjunction with the above object to so attach the steam
chest that considerably less heat is lost by radiation from the circular plate and
attachments thereto; and consists in making the steam chest of the comb circles in
sections and mounting between each section, adjustable guiding pullies to rotate in
contact with the turned surface of the rack flange on the reverse side to that of the
teeth; or the guide pullies may be dispensed with and the steam chest made adjustablo
and so constructed that it keeps the comb circles in a true circular path; or the
steam chest may be made with recesses at intervals in the flat surface of the same
such a depth so as to allow of the passage of an instrument so that on coming in
contact with the turned surface of the rack flange on the reverse side to that of the
teeth, the comb circle is kept in a true circular path; in any case a layer of non-
conducting material is inserted between the steam chest and bed plate for preventing
the free passage of heat from one to the other.
In describing our invention more in detail, reference is made to the accompanying
drawings in which Fig. 1. represents a plan of so much of a bed plate and large comb
circle of a circular combing machine as are required to illustrate our invention added
thereto.
Fig. 2. is a section through irregular line Z. Z..
Fig. 3. represents a plan of a portion of a bed plate and comb circle showing an
arrangement by which the guide pullies may be dispensed with.
Fig. 4. represents a modification of the same.
Fig. 5. a side view of a portion of a steam chest sunk to allow access to the rack
flange, and,
Fig. 6. a section through line X. X.
The circular bed plate A. is fixed in the usual manner but instead of making the
steam chest B. in one annular piece cast to or forming part of the circular bed plate A.
we construct it separate, and attach it to the said plate by screws, placing a layer of
non-conducting material C. such as asbestos between the steam chest and circular
bed plate A.
According to the arrangement shown by Figs. 1. and 2. the steam chest B. is made
in four sections, each section being secured to the bed plate, and connected together
by small pipes D. the steam being supplied to one of the sections circulates through
the same to the outlet pipe in another section; or each section may be provided with
a separate supply and outlet pipe.
In the space between each section of the steam chest B. we mount on a suitable
bracket a guiding pulley E. in such position that the face of each is in contact with
the turned surface of the rack flange F on the reverse side to that of the teeth for
driving the comb circle G, by which means the said circle is retained and free to
revolve in its true path; and each guiding pulley E. being made adjustable, the same
can be moved whenever desirable to compensate for the wearing of the flange For
the respective guiding pullies.
Our object may be accomplished without the guiding pullies E. by making the
steam chest B. in sections, and securing them to the circular bed plate A. in the

manner as before described and turning the circumference of the inner diameter of
the same at H. so that on the several sections of the steam chest B. being placed with
the circumference of the inner diameter at H. in contact with the turned surface of
the rack flange F on the reverse side to that of the teeth, the comb circle G is
retained, and free to revolve in a true circular path, the sections being adjusted or
kept in working contact with the turned surface of the rack flange by the adjusting
screws S.
The comb circle G. may be retained in its circular path by a modified arrangement
of the steam chest B, which is shown in part plan by Fig. 4. the steam chest B. being
made in one piece but is not a complete circle, and is cast or formed separate from
the circular bed plate A. to which it is secured by bolts. The internal circumference
of the steam chest at H. is turned to fit the rack flange F. on the reverse side to that
of the teeth and is adjusted or kept in working contact with the turned surface of the
rack flange F by a bolt K. passing through the two lugs L, one being formed on each
blank or stopped end of the hollow steam chest B. so that on the regulation of the
said bolt, the internal diameter of the steam chest may from time to time be adjusted
and thus keep the surfaces of the steam chest and comb circle flange in working
contact, thereby enabling the comb circle B. to rotate in a true circular path; the
steam chest being provided with the usual inlet and outlet pipes; and in securing the
said chest to the circular bed plate a layer of non-conducting material inserted
between the two as before described for preventing the free passage of heat from one
to the other.
The steam chest B. may be made in another form separate from the circular bed
plate A. and secured thereto clear of the comb circle flange in the manner as before
described and in order to keep the comb circle G in its true path, the steam chest B.
may be recessed at intervals as at B for allowing of the insertion of a screw M.
having a shoe, or block N. at the end thereof, against which rotates the turned surface
of the rack flange F. on the reverse side to that of the teeth for driving the comb
circle thus keeping the said circle in its true path.
;
When applying our invention to old machines, we first cut away the steam chest
from the circular bed plate A. by which we obtain room to apply and secure our novel
steam chest which is secured in the manner as hereinbefore described.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. The rotating comb circle of a combing machine combined with the steam
chest B. made in sections substantially in the manner and for the purpose as herein-
before described.
2. The rotating comb circle of a combing machine combined with the steam
chest B. terminating with blank ends and lugs L. arranged and operated substantially
in the manner and for the purpose as hereinbefore described.
3. The rotating comb circle of a combing machine combined with the steam
chest B. having recesses B' at intervals and the screws M. with the shoes N. arranged
and operated substantially in the manner and for the purpose as hereinbefore
described.
4. The combination of.a combing machine circular bed plate A. having a loose
steam chest attached thereto with a layer of non-conducting material between the
same for the purpose as hereinbefore described.
