PROVISIONAL SPECIFICATION.
Improvements in or relating to Clipping Machines for Wool or Hair.
We PHILIP ASHBERRY, of Burngreave Road, Manager, and WALTER BARNES,
of Intake Road, Ivory Carver, both of Sheffield in the County of York, do hereby
declare the nature of our invention to be as follows:—
This invention of improvements in mechanical clippers for cutting wool or hair,
relates more particularly to the method of and mechanism for coupling the clipper
to the end of the flexible shaft by which the driving motion is transmitted to the
reciprocating cutter.
The object is to provide means by which the shearer may uncouple and couple
the clipper to the shaft either when stationary or in motion, with rapidity and
certainty, and without the use of any tools.
I propose to construct the end of the flexible driving shaft as follows, the
termination of the actual shaft is of tubular form with a longitudinal slot through
each side to receive a projecting stud on each side of the driving spindle of the
clipper which can thus be pushed in and drawn out without any other motion, and
so requires some retaining action when in use.
Upon the end of the tubular cover round the flexible shaft, we attach a socket
piece in which the slotted end of the flexible shaft revolves, and in the enlarged
outer end of the said socket piece beyond the flexible shaft, a short stud projects
into the interior.
Upon the last joint piece of the clipper, which carries the end of the driving
spindle with the projecting studs above mentioned, we form a few turns of a coarse
screw thread, of such a diameter that will easily pass into the enlarged outer end
of the said socket piece, and that when pushed in will engage with the stud before
mentioned, and cause the socket piece to be drawn up against a shoulder on the
joint piece.
The clipper and the flexible shaft are thus coupled together without fear of
becoming loose or uncoupled, while to uncouple and detach the clipper whether the
shaft is either stationary or running, it is only necessary to give the clipper a few
turns in the right direction so as to disengage the coarse thread of the joint piece
from the stud in the socket.

Improvements in or relating to Clipping Machines for Wool or Hair.
WE PHILIP ASHBERRY, of Burngreave Road, Manager, and WALTER BARNES,
of Intake Road, Ivory Carver, both of Sheffield in the County of York 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 of improvements in mechanical clippers for cutting wool or hair,
relates more particularly to the method of and mechanism for coupling and
uncoupling the clipper to the end of the flexible shaft by which the driving motion
is transmitted to the reciprocating cutter.
The object is to provide means by which the shearer may uncouple and couple

page_text: the clipper to the driving shaft, either when said shaft is stationary or in motion,
with rapidity and certainty, and without the use of any tools.
The annexed sheet of drawings will illustrate the invention being a partly
sectional elevation of the apparatus in position for coupling.
We construct the end of the flexible driving shaft A, as follows; the terminal B,
which is attached to the shaft by a double ended screw C, has a deep longitudinal
slot D, on either side, to engage with the cross stud E, which projects from each
side of the spindle F.
The flexible shaft and its terminal are carried by a non-rotating shaft casing G,
which terminates in a socket H, having an inwardly-projecting radial stud I.
Upon the last joint piece J, of the clipper L, which instrument is not shown in
the drawing, and which carries the short driving spindle F, before mentioned, we
make a few screw threads K, of coarse or quick pitch, forming a screw plug, which
when passed into the socket H, of the other part, will engage and co-act with the
stud I.
It will be understood that when the two parts are being put together, the
studs E, on the spindle F, will enter the slots D, of the revolving terminal B, and
the spindle will be carried round, and frictional contact will cause the part J, and
screw K, also to revolve, and thus the two parts will be drawn together and be
retained in that position.
The clipper and the end of the flexible shaft can thus be coupled instantly and
without fear of becoming loose or uncoupled, while to uncouple and detach the
clipper when the shaft is either running or stationary, it is only necessary to give
the clipper a few turns in the proper direction to disengage the coarse pitch
screw K, from the stud I, in the socket H.
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 :-
1. The construction, arrangement, and combination of the several parts con-
stituting the means for coupling together a clipper and its driving shaft, substantially
as hereinbefore described and illustrated.
2. As a means for coupling and uncoupling the flexible driving shaft of a sheep
clipping machine, a slotted terminal B, and socket H with internal stud I, connected
with the said shaft, and upon the clipper, a projecting spindle F, having studs E,
and a quick thread screw K, substantially as hereinbefore described and with
reference to the drawings.
