PROVISIONAL SPECIFICATION.
[Communicated from abroad by ROBERT OBERNESSER, of Nomexy-Châtel,
Vosges, France, Cotton Mill Manager.]
Improvements in Apparatus or Machinery for Grinding Wire Cards.
I, GEORGE WHITELEY, of Oldfieldnook, Cleckheaton, in the County of York,
Card Manufacturer do hereby declare the nature of this invention to be as
follows:-
:-
This invention relates to improvements in that class of apparatus or machinery
for grinding or "pointing" wire cards (employed in machinery for carding fibrous
material) in which one or more rotary grinding wheels or discs is or are traversed
across the card and its object is to prevent the said wires being sprung or inclined
laterally by the traversing motion as this is found to be a frequent cause of
irregular grinding.
For this purpose one or more breaks, depressions or cut away portions is or are
formed in the periphery of each grinding wheel thereby breaking the continuous
contact of the wheel with the card and thus obviating the tendency to spring the
card wires laterally.
In practice two or more breaks or depressions are preferably formed in each
wheel or disc an equal distance apart so as not to interfere with the balance of
the wheel.

COMPLETE SPECIFICATION.
Improvements in Apparatus or Machinery for Grinding Wire Cards.
I, GEORGE WHITELEY, of Oldfieldnook, Cleckheaton, in the County of York,
Card Manufacturer, 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 relates to improvements in that class of apparatus or machinery
for grinding or "pointing" wire cards (employed in machinery for carding fibrous
material) in which one or more rotary grinding wheels or discs is or are traversed
across the card and its object is to prevent the said wires being sprung or inclined
laterally by the traversing motion as this is found to be a frequent cause of
irregular grinding.
For this purpose one or more breaks, depressions or cut away portions is or are
formed in the periphery of each grinding wheel thereby breaking the continuous
contact of the wheel with the card and thus obviating the tendency to spring the
card wires laterally.
In practice two or more breaks or depressions are preferably formed in each
wheel or disc an equal distance apart so as not to interfere with the balance of
the wheel.
Reference is to be had 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.

page_text: Figure 1, represents an elevation of such parts of a card grinding machine as
are necessary to illustrate the application of my improvements thereto.
Figure 2, is a separate side view of one of the improved grinding dises.
The screw A for traversing the grinding wheel Balong the hollow shaft (' is of
ordinary construction and may be arranged and operated in any ordinary way.
The grinding wheel B is preferably formed, in the manner now frequently adopted,
of a number of dises D' having pointed peripheries E. But these peripheries
instead of being circular or unbroken have portions F cut away thus allowing the
wheel to be freely traversed without springing the dents or card wires aside.
It is obvious that my improvements are equally applicable to other forms of card
grinding wheels.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
A wheel for grinding or "pointing" wire cards, having one or more depressions
or cut away portions in its periphery, substantially as herein shown and described
and for the purpose specified.
Datel this 19th day of December 1893.
