Improvements in Horse Clippers and the like.
I, MOTT GEORGE GILLETTE, of 46 Gray's Inn Road, in the County of
Middlesex, Manufacturer of Horse Clipping Machines, do hereby declare the
nature of this invention to be as follows:-
This invention relates to horse clippers and the like driven by flexible driving
shafts and comprises various improvements as hereinafter described.
According to my invention drive the oscillating knife plate through a lever
pivoted at or near its centre to the frame of the clipper and having a slot at
its outer end engaging a pin on the said knife plate. The inner end of the said
lever is made with a cylindrical eye having its axis parallel to the pivot pin of the
lever; the wall of the cylinder is slotted to admit the driving pin as hereinafter
described.
I place within the cylinder a loose fitting cylindrical plug in which is formed a
radial slot extending the whole length of the plug. The driving spindle to which
the flexible driving shaft is coupled is housed within the handle of the clipper in
the usual manner. The inner end of said spindle is bored with an excentric hole
parallel to the axis of the spindle to receive a loose fitting pin having a flat sided
head that projects through the slot or opening in the side of the cylinder and fits
within the slot of the before mentioned cylindrical plug and serves to oscillate the
lever about its pivot pin when the driving spindle is rotated.
The interposition of the lever in the driving mechanism and the slotted
cylindrical plug in the end of said lever constitute the chief features of my
invention.
In some instances especially when a long lever is used, I provide a series of
balls to support the lever for the purpose of reducing the friction. The balls are
arranged to roll in short grooves or recesses formed in the frame of the clipper
and in the face of the lever.
A further improvement according to my present invention relates to the tension
device which consists of a screw passing through a part of the frame and bearing
on the back of the cover plate of the oscillating knife plate. This screw is
furnished with a lock nut to lock the screw in any position to which it may
be Bet.

Improvements in Horse Clippers and the like.
I, MOTT GEORGE GILLETTE, of 46 Gray's Inn Road, in the County of
Middlesex, Manufacturer of Horse Clipping Machines, 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 more particularly to hair clippers of the kind in which a

page_text: reciprocating serrated cutter is employed in conjunction with a stationary serrated
cutter or comb.
An essential feature of my invention consists in operating the reciprocating
cutter by a pivoted lever one end of which engages loosely with a pin or stud in
the reciprocating cutter and the other end of which carries a loose cylindrical plug
or block which is slotted longitudinally to receive the head of a loose eccentric
pin projecting from the end of the driving spindle.
For regulating the pressure with which the reciprocating cutter bears on the
stationary cutter I prefer to employ a tension device consisting of a set-screw
which is carried by the frame of the clipper and bears upon the cover plate of the
reciprocating cutter. By tightening this set-screw the cover plate can be caused
to press the cutters together with more or less force. The set-screw is provided
with a lock-nut for retaining it in its adjusted position.
The aforesaid pivoted lever may be supported by anti-friction balls.
In order that my said invention may be clearly understood and readily carried
into effect I will proceed to describe the same more fully with reference to the
accompanying drawings, in which:
Figure 1 is a plan
Figure 2 a longitudinal central section, and
Figure 3 a horizontal section on the line 1.1. of Figure 2, the driving spindle
being in elevation.
Figure 4 is an elevation of the inner end of the driving spindle with its
eccentric pin.
Figure 5 is a front elevation and Figure 6 a side elevation of the pivoted
lever.
Figure 7 is a front elevation and Figure 8 a side elevation of the loose
cylindrical plug or block.
Figure 9 is a front elevation and Figure 10 a side elevation of the loose
eccentric pin.
A is the frame or casing of the clipper, B the stationary serrated cutter or
comb, C the reciprocating serrated cutter, and D the driving spindle which is
housed within the handle portion A' of the frame of the clipper. The free end of
this spindle is, as is usual with clippers of this description, connected to the end of
a flexible shaft driven by any suitable machine.
E is the pivoted lever which is forked at its upper end to receive a pin or stud c
projecting from the reciprocating cutter.
The opposite end of the said lever E is formed with a cylindrical eye or socket e
the axis of which is parallel with the pivot pin ex of the said lever E, that is to
say it is at right angles to the plane of movement of the lever. F is the cylin-
drical plug or block which loosely fits into the cylindrical eye or socket e and is
formed with a radial slot f that extends from end to end of the plug.
The inner end of the spindle D is provided with a cylindrical head D¹ having
formed eccentrically therein a longitudinal hole for the reception of the loose pin d.
This pin has a flattened bead which is adapted to enter the aforesaid slot in the
cylindrical plug F, the wall of the said eye or socket e being slotted to permit the
head of this pin to enter the said slot f.
The said eccentric. pin d serves to oscillate the lever E about its pivot when
the driving spindle is revolved, and by reason of this pin being mounted loosely in the
end of the driving spindle and of the cylindrical plug being loosely carried by the
lever E, the aforesaid head of the pin d will reciprocate evenly in the slot where
it has a considerable bearing surface. Undue wearing of these parts and much
friction are therefore avoided with the result that a more even and regular
movement is obtained than heretofore.
The aforesaid stationary knife or comb B is firmly connected to the frame or
casing A of the clipper by screws bb and said knife or comb is formed with
rectangular holes b¹ for the reception of rectangular stumps or posts g projecting
inwardly from the cover plate G; lateral movement of the said cover plate is

page_text: thereby prevented. These posts pass through slots c* in the reciprocating knife C
and thereby permit the said knife to freely participate in its reciprocating move-
ments. The cover plate is formed with flanges g¹g the former of which bears
upon the surface of the knife C. H is a set-screw carried by an arm A' projecting
centrally from the frame or casing A of the clipper. By turning the head H¹ of
this set-screw its inner end can be caused to bring the flange g' of the cover plate
with more or less force against the cutter C and the frictional contact between
the two knives can thus be increased or diminished as desired. 'H' is a lock nut
for securing the screw H in its adjusted position.
In cases where the aforesaid lever E is made longer than that shewn in the
drawings, I may employ anti-friction balls or rollers contained in a slotted cavity
formed in the frame or casing of the clipper at some point between the fulcrum
and the driven end of the lever. The lever would then bear on these balls or
rollers during its oscillations.
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 :-
1. In a hair-clipper the combination with the pivoted lever employed for
operating the reciprocating knife, of a slotted rotary plug or block and of a
loose eccentric pin on the driving spindle substantially as described and for the
purpose specified.
2. In a hair-clipper the combination with a loose cover plate having posts 9 and
flanges gg, of a set-screw having a locking nut and carried by an arm A¹
substantially as described and for the purpose specified.
3. A hair-clipper having its parts constructed arranged and combined to operate
substantially as described with reference to the accompanying drawings.
