Specification Accepted, 24th May, 1887.
We THOMAS LOVELL PHIPPS and William BURMAN both of Ryland Road, Edgbaston
Birmingham, in the County of Warwick, Manufacturers, do hereby declare the
mature 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 :-
Our invention has for its object principally, the production of hair clippers, for the
clipping and shearing of horses and other animals, but our said invention, is also for
the cutting of the human hair, and for the clipping of hedges and the like: and the
said invention consists in interposing between the underside of the cap or caps or
handle, or a combined cap and handle, and the plain upper side of the top cutter
plate, anti-friction balls or spheres, which work within longitudinal grooves, formed
within the undersigned of the said cap or caps, or parts as aforesaid.
By which means, the cutiers are more easily worked, by reducing frictional contact
between the hearing surfaces and working parts; and which said invention is an
improvement upon Letters Paient granted to us on the Seventh day of July 1885
numbered $204.
We will now proceed to describe with reference to the accompanying Drawing,
the manner in which the same is to be performed.
Figure is a plan (partly in section) of a horse clipper provided with two ball
bearing surfaces. Figure 2 represents a transverse vertical suction of the same on
the dotted lines A B. Figure 3 is a longitudinal section, showing the positions of
the two ball bearings, and the long recesses, wherein they roll or traverse. Figure
4. is a longitudinal section of the cap separately, figure 5 is an underside plan of the
same, figure 6 is a cross section on the dotted lines CD. Figure 7 is a plan (partly
in section) of a clipper provided with three ball bearing surfaces instead of two, as
in figure 1. The breaking away of the top of the said cap, is to thus exhibit the
ball bearing surfaces, and the longitudinally disposed recesses wherein the balls
traverse, on the reciprocation of the plates, when the clipper is in use.
The same letters of reference indicate corresponding parts in the several figures of
the Drawing.
a is a lever, and a² is a cap or cover. (separate from each other in figure 1, but
combined in one in ligure 7) having upon its underside, long recesses, disposed in

page_text: e'
the longer direction of the cutier plaies; and within these recesses, balls or spheres c
are placed, and which are prevented from falling out by slightly closing over the
surrounding metal, as best seen in figures 5 and 6,″ d is the top cutting plate, and
is the under cuting plate; and it is between the plain top of the said plate d, and the
tops of the insides of the recesses formed in the underside of the cap, that the balls
or spheres e roll; by this means, the frictional contact between a² and c, is reduced to
a minimum, and the clipper thereby made to work more easily, and the wear of the
contact and working surfaces greatly reduced. are studs on the underside of the
cap, which take into corresponding holes in the bottom plate, and through long slots
in the top plate. / is a cutterplate securing pin, and " is a screw nut is a lever
connecting pin, which proceeds upwards from the face of the under lever h. The
lever a has upon its front end, a short arm a', by which means, the reciprocating top
plate is worked, by engaging within a gap in the said plate, as in figure 1, or between
square studs as in figure 7. The levers are secured in position by a nut ², screwing
upon the end of the pin y.
The balls or spheres as aforesaid are held within their long recesses, by slightly
closing or spreading the surrounding metal of the open tops of the said recesses, over
the tops of the balls or spheres contained within them, and which said drawn over
surrounding or overhanging metal, is marked at. The drawing over of the metal
aforesaid, prevents the balls or spheres from falling out of their said recesses, when
the parts of a clipper are taken to pieces.
Or instead of the surrounding metal being drawn over the tops, it may be drawn
over the ends or other paris, as indicated in the Specification of our former Letters
Patent No. 8204 and dated July 7th 1885 before cited.
Figure 7 is a spring cap, instead of being made rigid.
Having now particularly described and aseeriained the nature of our said invention,
and in what manner the same is to be performed, we declare that what we claim is ;-
First. In a ball bearing clipping or shearing machine. Interposing between the
underside of a loose covering eap or caps, or the underside of the cap of a combined
cap and handle, and the plain upper side of the top culter plate, rolling and loose
working anti-friction balls or spheres, whereby frictional contact between the hearing
and working surfaces, are greatly reduced; substantially as described and set forth.
Secondly. Disposing the long sockets or recesses, wherein the ball bearings roll,
and loosely work, in the longer direction of the covering cap, or cutier plates; or in
the direction in which the top cuiter plate works, substantially as set forth.
Thirdly. Holding anti-friction balls or spheres within their recesses, or within
their long recesses, by making the open boundary edges of the said recesses slightly
overhang the balls or spheres, either by a closing or drawing in process, or by partly
drilling and partly closing in (the ends) for the purpose substantially as described and
set forth.
Dated this Seventh day of March 1887
THOMAS LOVELL PHIPPS,
WILLIAM BURMAN.
