We, WILLIAM BOWN, of 308 Summer Lane Birmingham in the County of
Warwick, Manufacturer, and, GEORGE CAPEWELL of 17 Victoria Place, Potters
Lane Aston, near Birmingham aforesaid, Machinist do hereby declare, the nature
of our said invention for "IMPROVEMENTS IN MACHINES OR APPLIANCES FOR
CLIPPING OR SHEARING HAIR, WOOL, OR OTHER LIKE MATERIAL, OR SUBSTANCE,"
to be as follows:-
Our improvements have for their object the diminishing of the friction in the to
and fro movement of the cutting plates of clipping or shearing machines whether for
wool, hair, or other substance.-In carrying our improvements into effect, we take
for example, say, an ordinary clipping machine, one which has the top cutting
plate held in position by a triangular or other shaped bar, to which we connect or
attach one or more oscillating quadrants or segments with or without projections,
holes, slots, or their equivalents on the sides or ends; or cog wheels may be used
for this purpose.
For preference, we use two of these quadrants, or segments, in an upright
position, the points of the quadrants or segments bearing against the bar, the outer
edges or peripheries bearing against the top of the cutting plate or other bearing
surface, or vice versâ.
When the cutting plate is moved to and fro by the working of the handle, the
parts of the quadrants or segments bearing against the bar oscillate upon their
points, while the outer edges or peripheries make an antifrictional movement on
the cutting plate or bearing piece. To ensure perfect oscillation, we sometimes
use the said projecting pieces on the sides or ends of the quadrants or segments
working in corresponding holes, slots, or their equivalents in the cutting plate, or
bearing piece, or vice versa.
The quadrants or segments are preferably-connected to the bar so that when
taking the clipper to pieces for cleaning or otherwise, the said quadrants, or
segments, will not be detached from the bar.

page_text: When necessary we provide a spring cap which covers the bar and parts thereby
excluding all dirt, grit, or other impediment to the proper working of the clipper.
This improved system of reducing the friction in the working of the plates may
be applied to other parts of the clipper if found desirable.
When applying our improvements to other clipping machines than those with
the triangular or other shaped bar, we attach the quadrants segments or pieces to
an independent holder, holders, or clamping pieces, made in any suitable or con-
venient form.

We WILLIAM BOWN of Birmingham in the County of Warwick Manufacturer
and GEORGE CAPEWELL of Aston near Birmingham aforesaid Machinist do hereby
leclare the nature of our said invention for IMPROVEMENTS IN MACHINES OR
APPLIANCES FOR CLIPPING OR SHEARING HAIR WOOL OR OTHER LIKE MATERIAL OR
SUBSTANCE 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 for their object the diminishing of the friction in the to
and fro movement of the cutting plates of clipping or shearing machines whether
for hair wool or other substance.
In carrying our improvements into effect we take for example say an ordinary
clipping machine one which has the top cutting plate held in position by a
triangular or other shaped bar to which we connect or attach one or more
oscillating quadrants or segments with or without projections holes or slots or
their equivalents on the sides or ends or cog wheels may be used for this purpose.
By preference we use two of these quadrants or segments in an upright position
the point or top part of the quadrant or segment bearing against the bar, and the
outer curved edge or periphery bearing against the top of the cutting plate or
other bearing surface or vice versa.
When the cutting plate is moved to and fro by the working of the handle the
parts of the quadrants or segments beating against the bar oscillate upon their
points or top parts while the outer curved edges or peripheries make an anti-
frictional oscillating or rolling movement on the cutting plate or bearing piece.
But as our improvements will be best understood by referring to the drawings
hereunto annexed we will describe the same reference being made to the figures
and letters marked thereon.
Figure 1. is a top view of the clipper in which the top cutting plate A A is held
in position by the triangular or other shaped bar B; and to this bar we connect or
attach the oscillating quadrants or segments in an upright position as shown in
dotted lines in Figure 1. marked C. C. also in detached underside view transverse
and longitudinal sections of the bar B. at Figures 2. 3. and 4. aud in a detached view
of the quadrant or segment C. at Figure 5. the outer curved edges or peripheries
of these quadrants or segments C. bearing against the top of the cutting plate A A
as seen at Figure 4. the points or ends a. a. of the quadrants or segments C.
bearing against the underside of the bar B. and held in position by preference by a
small set pin passed through the side of the bar as shown in dotted lines in
Figure 1 marked b. and in section at Figure 3.-When the cutting plate A is
moved to and fro by the working of the handle D the parts or points a. of the
quadrants or segments C. C. oscillate against the recessed part of the underside of
the bar B. (see figure 4.) while the outer curved edges or peripheries of the
quadrants or segments C. C. make an antifrictional oscillating or rolling movement

showing the back part or tail E. of the bar B. resting on a ledge or projection F on
the fixed or top lever G which forms a steadying seat for the back part of the
bar B.
To ensure perfect oscillation we sometimes use projecting pieces on the sides or
ends of the quadrants or segments C. C. working in corresponding holes slots or
their equivalents in the cutting plate or other bearing part or vice versa.
quadrants or segments C. C. are by preference connected to the bar B. so that when
The
taking the clipper to pieces for cleaning or otherwise the quadrants or segments C. C.
will not be detached from the bar B.
When necessary we provide a spring cap which covers the bar B. and parts,
thereby excluding all dirt grit or other impediment to the proper working of the
clipper This improved system of reducing the friction in the working of the
plates may be applied to other frictional parts of the clipping or shearing machine
if found desirable.
When applying our improvements to other clipping or shearing machines than
those with the triangular or other shaped bar B. as before described we attach or
connect the quadrants or segments C. C. to an independent holder, holders or
clamping pieces made in any suitable or convenient form.
Having now described our improvements we wish it understood that what we
claim as our invention and wish protected by letters patent is
The construction of machines or appliances for clipping or shearing hair or other
material or substances substantially as herein described and exhibited by the use of
quadrants or segments or their equivalents in connection with the top cutting
plate or other bearing parts by which means the friction of the parts is greatly
reduced.
