Improvements in Combing Machines.
We, ALBERT SMITH, of the firm of John Smith and Sons, Limited, Fieldhead
Mills, Bradford, in the County of York, Worsted Spinner, and HENRY WALTON
WHITEHEAD, of the firm of Taylor Wordsworth & Co., Water Lane, Leeds, in
the said County, 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 :-
The object of our invention is to construct the driving mechanism of combing
machines in such a manner as to greatly reduce the liability of the machines
executing inferior work by reason of the frequent breakages of the slivers as they
are fed to the machine on starting the same in the morning after standing all night,
or when commencing to comb a new lot of fibre, and to be enabled to put the
machine up to the proper rate of speed when the comb circles and adjacent parts
have become heated to the requisite temperature and the slivers begin to leave the
feed rollers freely.
In the accompanying drawings Fig. 1 represents an elevation of our improve-
ment partly in section applied to the upper portion of a "Noble's" combing
machine. All the other parts of the machine not shown are ordinary and do not
constitute any part of our invention.
Fig. 2. is a plan of the same.
Fig. 3. a section through line a. b.
Fig. 4. a section through line c. d. and
Fig. 5. a plan showing a modified arrangement.
To the ordinary pillars A. A. of a "Noble's" combing machine, we secure
brackets B. B. for supporting a counter shaft C. upon the centre of which is
mounted a loose pulley D. The pulley E is keyed on the counter shaft C. as is
also the spur wheel F. which gears with the spur wheel G of larger diameter
keyed on what is known as the top or driving shaft H of the machine: by this
arrangement the top shaft H is driven at a slower rate than the counter shaft C.
therefore the machine at a proportionate reduction in speed whenever required such
as on beginning work in the morning or commencing to comb a new lot of fibre.
The pulley Jis prepared with a long boss for the reception of the spur wheel K.
which is keyed thereon and gears with the spur wheel L of smaller diameter keyed
on the top shaft H. so that when the driving belt M is on pulley J. the top
shaft H. will run at an increased speed, and therefore all the other parts of the
machine which are driven from the shaft H in the usual manner.
In Fig. 5 a modification is shown by which we may also accomplish our object.
According to this arrangement, we place the three pullies on the top shaft H of the
machine, the centre pulley D being loose on the shaft the same as when mounted on
counter shaft C; the pulley E is keyed on top shaft H. as is also the spur
wheel F which gears into the spur wheel G of larger diameter keyed on the
counter shaft C on which is also keyed another spur wheel L gearing with spur
wheel K of larger diameter and keyed on the long boss of pulley J. which is
mounted loose on the top shaft H. so that on the belt M running on the centre
pulley D. the machine is at rest, and when placed to run on the pulley E. the
top shaft H. will rotate at the speed of said pulley E. but when the belt is moved
to run on the pulley J. the speed of the top shaft increased by the spur wheels
arranged in the manner described; thus by these means hereinbefore described, the
machine may be run at two different speeds as may be required by the condition of
the slivers and temperature of the comb circles, which as is well known by those
conversant with combing, the latter requires to be at a temperature proportionate
to the speed of the combing machine.

page_text: Having now particularly described and ascertained the nature of our inven-
tion, and in what manner the same is to be performed, we declare that what
we claim is:-
:
The top shaft H of a combing machine combined with a counter shaft C or C¹
pullies D. E. and J..and the spur wheels F. G. K. and L. arranged substantially in
the manner as hereinbefore described whereby the machine may be at rest or run
at different speeds on moving the driving belt M from one pulley to another.
