Improvements in the Leather Traversing Motion of Noble's Combing
Machines.
I, DAVID HIRD, of 95, Harewood Street, in the City of Bradford, Combing Over-
looker, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in the motion for traversing the leathers
of the drawing off rollers of Noble's combing machines; and its object is to
heart" or
dispense with the pawl and ratchet usually employed to drive the
cam and drive such heart or cam by a continuous motion.
For this purpose I fix a sprocket wheel on the outer end of the cam shaft
and I drive this sprocket wheel by a chain from an adjacent sprocket wheel.
This latter sprocket wheel is fixed on a short shaft mounted in an attachment
to the underside of the steam chest and this short shaft may be driven by a
worm wheel engaging a worm on a vertical shaft driven by a pinion engaging and
driven by the rack.
The cam shaft may be driven from the short shaft by spur wheels instead of
a chain. Or the cam shaft may be driven direct by a worm and worm wheel.

I, DAVID HIRD, of 95, Harewood Street, in the City of Bradford, Combing Over-
looker, 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:―

To fully describe my invention reference is made to the accompanying sheet of
drawings, forming a part of this specification, in which similar letters of reference
indicate corresponding parts in each of the figures.
Figure 1, is an elevation of my improved motion.
Dimina is a plan view of the same.

page_text: The broken line A in Figure 1 represents the underside of the steam chest upon
which the annular rack carrying the large circle revolves, and the shaft B shown
broken away in Figure 2 is the cam shaft of the leather traversing motion usually
driven by a pawl and ratchet.
In this case I fix a sprocket wheel C on the outer end of the shaft B in place of the
usual ratchet wheel and I drive this wheel by the chain 1), from the sprocket
wheel mounted upon the stud F projecting from the bracket or attachment G
fixed to the underside of the steam chest. A worm wheel H is fixed on the boss J
of the wheel E and this worm wheel engages the worm K on the vertical shaft L
mounted in the attachment G. The shaft L is driven by the pinion. O fixed upon
its upper end engaging and driven by the annular rack above referred to.
It will be readily understood that when the comb is in operation a continuous
and uniform motion is given to the leather traversing shaft B.
The shaft B may be driven from the wheel H by spur wheels instead of a
chain and sprocket wheels. Or the cam shaft may be driven directly from the
rack by a worm and worm wheel when the construction of the comb will permit
the worm K and pinion to be placed sufficiently near to the shaft B.
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
1. In a Noble comb, the combination with the pinion 0 arranged to be driven
by the rack of the large circle of, the worm K driven by said pinion and
engaging a worm wheel H arranged when in operation to impart a continuous
motion to the leather traversing shaft, substantially as herein shown and
described.
2. The combination with the pinion 0, worm K, worm wheel H, and the
sprocket wheels E and C coupled together by a chain, all arranged and operating,
substantially as herein shown and described and for the purpose specified.
