PROVISIONAL SPECIFICATION.
Improvements in and relating to Hair or Toilet Clipping Machines.
I, JOHN RAE of 147 Stockwell Street, Glasgow, Lanarkshire, Trade Cutler do
hereby declare the nature of my invention to be as follows:-
This invention has reference to and comprises improvements in the construction
or arrangement and combination of the parts of portable hair or toilet clipping
or cutting machines held and worked by the hand as used by barbers and others,
whereby these machines will be enabled to work in a more efficient and satisfactory
manner, and be more easily repaired in the event of their getting broken.
These hair clipping machines as heretofore constructed consisted of a lower fixed
plate formed with a series of teeth on its front transverse end, and a correspondingly
formed plate with similar front teeth, mounted by pins and slots over this, and
which receives a transverse motion to perform the clipping or cutting operation by
means of a projecting arm on a hand operated lever mounted on a central stém or
spindle.
A helical or spiral spring is mounted round this spindle having its one end
bearing on a bridge part or eye on the lever, and having its other end bearing on
an adjustable screw pin which regulates the tension of spring, and the action of
this spring is by its recoil to move the upper transverse reciprocating cutting plate
in the one or opposite direction to that in which it is moyed by the action of the
hand. The whole is enclosed, except the cutting parts, by an upper plate mounted
over the spindle and held down over the cutting blades by a thumb screw nut, the
plate being also preferably formed with a projecting handle which is gripped by the
thumb when working the movable projecting handle or hand lever by the fingers.
With this construction of instrument considerable difficulty and time is lost in
replacing the spring should it get broken, and also in manipulating the hair cutting
operations by the projecting out straight fixed and movable handles. To overcome
these objections, my improvements consist first in dispensing with the enclosed
helical spring and its adjusting screw, and bearing bridge part, and in fitting a
volute or telescopic or equivalent acting spring outside the casing between the
fixed and movable handles.
This spring would preferably be formed as a double acting telescopic or
volute blade spring and have its two ends mounted over projecting pins formed
on the inner adjacent: sides of the fixed and movable handles, preferably about
midway of their length or near their inner ends. As the handle or hand lever
is moved by the fingers in one direction to move the upper cutting plate in one
transverse direction the spring. is compressed to move telescopically inwards,
and the recoil of this spring will move or reciprocate the cutting blade plate in the
opposite direction. With this arrangement should a spring get broken it can be
easily, and quickly replaced by mounting a new spring on the projecting studs of
and between the handles.
By a further improvement instead of fitting the fixed and movable handles to
project straight out behind the cutting blades, they would be placed at an angle or
to one side of the instrument the movable one being nearly parallel with the
reciprocating blade in its forward travel, so that the barber can work with greater
freedom, and in a more perfect manner, and with more comfort to the party being
operated on than with the formerly arranged handles.

As heretofore constructed the top toothed plate received a motion which made it
reciprocate a distance of two teeth over the lower fixed plate, but by forming
longer slot in it, and lengthening or adjusting the arm of the band lever which
actuates this plate, the inovable plate will be made to travel or reciprocate a
distance of three teeth over the lower fixed toothed plate.

COMPLETE SPECIFICATION.
Improvements in and relating to Hair or Toilet Clipping Machines.
I, JOHN RAE, of 147 Stockwell Street, Glasgow, Lanarkshire, Trade Cutler,
do hereby declare the nature of my invention, and in what manner the same
is to be performed to be particularly described and ascertained in and by the
following statement in writing, that is to say :-
This invention has reference to and comprises improvements in the construction
and arrangement of the parts of portable hair clipping or cutting machines worked
by hand, as used by barbers and others, whereby these machines will be enabled
to work in a more efficient manner and be more easily repaired.
And in order that my said invention and the manner of performing or carrying
same into practice may be properly understood I have hereunto appended an
explanatory drawing illustrating a hair cutting machine as constructed and fitted in
accordance with my improvements.
Referring to said drawing:-The improvements consist first in dispensing with
the helical or other spring usually enclosed between the upper and lower toothed
plates of the machine, and its adjusting screw and bearing bridge or eye part, and
in fitting a volute or telescopic or equivalent acting spring A outside of the casing
and between the fixed handle B and movable handle C. This spring A would
preferably be a double acting telescopic or volute blade spring, formed of a ribbon
of steel divided longitudinally to near its outer coiled end, and have its end mounted
on projecting pins or studs D formed on the inner adjacent sides of the fixed and
movable handles B, C.
As the handle or hand lever C is moved by the fingers in one direction to move
the upper cutting plate E in one transverse direction the spring A is compressed
telescopically inwards, and the recoil of this spring will reciprocate the cutting
plate in the opposite direction. In the case of a spring breaking it is easily
removed and a new one inserted.
By another improvement instead of fitting the fixed and movable handles B, C,
as usual to project out behind and almost at right angles to the cutting plate, they
are placed at an angle or projecting towards one side of the machine the movable
one being nearly parallel with the reciprocating plates when pressed inwards to
move the cutting plate, so that the operator can work with greater freedom, and in
a more perfect manner and with more comfort to the party being operated on than
with the handles as usually arranged.
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 :-
First. In hair or toilet clipping machines, the fitting and use of a volute or
telescopic or equivalent acting spring between the fixed and movable handles
substantially as herein described in reference to and shown in the accompanying
drawings.

page_text: Second. In hair or toilet clipping machines, the placing of the handles at an
angle or towards one side of the machine and acting in combination with a spring,.
substantially as and for the purposes set forth
