PROVISIONAL SPECIFICATION.
Improvements in Combing Machines.
We, JOHN CHARLES WALKER, and JONATHAN EDWARD STEPHENSON, both of
Shipley Fields Mill, Shipley, near Leeds, in the County of York, Engineers, do
hereby declare the nature of this invention, to be as follows:-
Our improvements have reference to Noble's and other kindred combing machines.
Firstly. In order to cause the large and small comb circles to rotate with greater
steadiness, we provide runners in a convenient manner underneath the rack circles,
having their peripheries or steadying surfaces running in a diagonal line to the plane
of movement of the rack circles. These runners may be fixed to the rack circle plate
and rotate with it, or they may be placed on any suitable part of the steam chest or
framework of the machine, working against a suitable angular ring, such ring being
formed on the rack circle, and whereby such rack circle is supported on the runners,
or the angular runners may be mounted on the rack circle and travel round therewith,
and revolve on or against a ring having an angular surface, such ring being applied
underneath the rack circle.
Secondly. The circular steam chest for imparting heat to the circular combs have
hitherto been made of hollow cast iron form, requiring careful casting, and also
requiring a core to form the internal space for steam. Now in our improvements we
make the steam chest of a trough form, and apply a thin metal plate cover on the top,
such cover being rivetted, soldered or otherwise secured to the top, so as to render it
steam tight. By this arrangement we provide a steam chest of larger steam capacity,
the heat is given off with much greater readiness at the point at which it is required,
also the construction of the steam chest is much simplified, and the risk of blown
castings is obviated.

Improvements in Combing Machines.
We, JOHN CHARLES WALKER and JONATHAN EDWARD STEPHENSON, both of
Shipley Fields Mills, Shipley near Leeds in the County of York, Engineers, 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:
Our improvements have reference to Nobles and other kindred Combing Machines.
Firstly. In order to cause the large and small comb circles to rotate with greater
steadiness we provide runners underneath the rack circles, baving their peripheries or
steadying surfaces running in a diagonal line to the plane of movement of the rack
circle.
In the accompanying drawings Figs. 1. 2. 3. 4. 5. 6 and 7, shew various modes of
applying the herein before mentioned runners.
We have marked the parts which correspond in each figure with corresponding
letters in all of which A represents the rack circle, B the steam chest and C the
framework of the machine. In Fig. 1, D is the runner or V pulley, mounted on a
stud or bracket E attached to the framework; any required number of such pulleys
may be provided round the machine. Underneath the rack circle A is provided
V piece or ring F whereby the rack circle is supported on the runners or pulleys D
steadying it thereby. In Fig. 2 we provide any required number of pulleys G at an

page_text: angle to the rack circle A, and mounted on a suitable bracket H attached thereto.
The outer edge of the flange of the steam chest is bevelled upon which the runners G
revolve, steadying the circle in its wovement. In Fig. 3 we provide any required
number of runners K,.mounted on brackets L attached to the framework C, and
underneath the rack circle A we provide an annular projecting piece M, these
runners K are in contact with the annular face of the projecting piece, steadying the
movement of the rack circle thereby. Fig. 4 is very similar to Fig. 2. In this case
the runners N are mounted on a bracket O attached to the underside of the rack
circle A, working in connection with the bevelled face of a ring P attached to the
framework C. By this arrangement also great steadiness is imparted to the rack
circle as it revolves. In Fig. 5 we employ a number of double coned horizontal
runners Rattached by suitable brackets R' to the underside of the rack circle A and
revolve as the circle rotates in a V grooved ring S attached by suitable bracket T to
the framework C, steadying the circle thereby. In Fig. 6 we employ vertical
bevelled runners T mounted on studs underneath the rack circle A. In this arrange-.
ment the bevelled runners revolve against the bevelled face of a ring U attached by
suitable bracket V. to the framework, imparting great steadiness to the rack circle as
it revolves. Fig. 7 is very similar to Fig. 6 except that the ring W is made of
V form to contain the oil, and the runners X slightly altered in shape to suit such
Vring, thereby steadying the rotating circle.
Secondly. The circular steam chest for imparting heat to the circular combs have
hitherto been made of hollow cast iron form, requiring careful casting and also
requiring a core to form the required internal space for steam. Now in our improve-
ments we make the steam chest of a trough form as shewn at Fig. 8, and apply a thin
metal plate cover Y on the top, such cover being rivetted, soldered or otherwise
secured thereto so as to render it steam tight. By this arrangement wo have a steam
chest of large steam capacity, the heat being given off with much greater readiness at
the point at which it is required, also the construction of the steam chest is much
simplified and the risk of blown castings is obviated.
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 :-
1st. The arrangement and application of pulleys or runners, and angular rings or
parts upon which the runners or pulleys revolve, such pulleys or runners and angular
rings or parts having their peripheries or steadying surfaces in a diagonal line to the
plane of movement of the rack circle, whereby greater steadiness is imparted to such
rack circle when in motion, substantially as herein set forth and shewn in the accom-
panying drawings.
2nd. The arrangement and construction of steam chest, having a thin plate or
cover fixed on the top, substantially as and for purposes herein set forth.
