Office of the Commissioners of Patents, with his Petition, on the
6th August 1878.
I, THOMAS LOVELL PHIPPS, of Aston, near Birmingham, in the County
of Warwick, Mechanical Engineer, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN CLIPPERS FOR CLIPPING HORSES AND
OTHER ANIMALS," to be as follows:-
My Invention consists of the construction and combination or arrange-
ment herein-after described of the parts of clippers for clipping horses
and other animals.
The gutters consist of two parallel plates having serrated edges as in
clippers of the ordinary kind. The moveable cutter is connected with
the fixed cutter by means of a slot in the said moveable cutter parallel
to its cutting edge, a rib-like projection on the fixed cutter of the same
width as but shorter than the said slot engaging in the said slot. By
this means the moveable cutter is guided and the parallelism of its
motion preserved upon the fixed cutter. A screw at the middle of the
projection described is fitted with a screw nut. The said screw has a

page_text: screw, a square hole in the middle of the said bow spring fitting on the
square shoulder at the base of the screw. By advancing the screw nut
described to a greater or less distance on the said screw, the said bow
spring may be brought into any required state of tension, and the said
bow spring may thus be made to press the moveable cutter in contact
with the fixed cutter with any required degree of pressure. The
moveable cutter being thus kept to its bearing on the fixed cutter by a
spring, its action is more certain and uniform than when it is adjusted
by screws or other fixed bearings.
The moveable cutter is covered by a case or cover which is fixed at its
centre by the screw and screw nut which serve to secure the bow spring
described.
.
The moveable cutter is worked by a moveable handle or lever turning
on a pin or axis on the fixed cutter, the short arm of the said lever
taking into a slot in the edge of the said moveable cutter. The clipper
is held while being worked by a fixed handle. On the motion of the
moveable handle or lever a reciprocating motion is given to the moveable
cutter, and the the clipping is effected by the serrated edges of the
two cutters in the ordinary way.
The fixed and moveable handles are connected to the plate of the
fixed cutter in the following manner :-On the under side of the head of
the fixed handle are two studs which take into holes in the fixed cutter.
The head of the fixed handle is hollow or cut away, and the head of the
moveable handle or lever is passed under the hollow head of the fixed
handle. By passing a screwed pin through holes in the said heads and
fixed cutter and screwing a nut on its end, the said two handles are
securely connected to the fixed cutter, the screwed pin described consti-
tuting the axis on which the moveable handle or lever turns. By this
arrangement the head of the moveable handle has a bearing both at top
and bottom. The sides of the cut-away part in the head of the fixed
handle serve as stops to limit the motion of the moveable handle or
lever.

standing in the middle of the said recess.
The spring in this modification has the following form:-Its middle
portion is concave, and its ends are convex. When put in its place on
the screw the middle concave portion of the spring enters the recess in
the fixed cutter, and the said spring is made thereby incapable of motion
about the screw as a centre. The convex ends of the spring press upon
the moveable cutter while the middle portions of the spring passing
through the slot in the moveable cutter serve as guides to the moveable
cutter, and preserve the parallelism of its motion.
