A DYNAMO-ELECTRIC HORSE-CLIPPER
Year: 1885

page_text: I CHARLES DE SALAZAR of 13 Arundel Street Haymarket London in the
County of Middlesex Electrical Engineer do hereby declare the nature of my
invention for "A DYNAMO-ELECTRIC HORSE-CLIPPER" to be as follows :-
My invention consists of fixing to ordinary horse clippers or others of more
suitable size, between the handle and the scissors two induction rings with electric
motor this new disposition allows also for diminishing the weight and size of the
clipper.
The circular rotary movement caused by the electric motor is transformed into
and gives to the scissors an alternating rectilinear motion by a system of articu-
lating levers which diminish and regulate the speed of the motor and scissors which
otherwise would be too great and this also allows for considerable increase of power
in the clipper.
This motor can be kept in action by any ordinary electric battery which may be
attached to or carried by the person using the clipper.
The action of the clipper is noiseless rapid and devoid of all danger, it also can
be worked with one hand only thereby allowing of the free use of the other.
To further describe the action of my Dynamo electric horse clipper, I place the
two induction rings side by side almost touching one another one is a fixture and
connected to the immoveable portion of the clipper, whereas the other revolves
having about its centre a pivot or axle which also revolves with it and passes
through the centre of the fixed ring, to this axle is attached an arm furnished with
a pin which is eccentric and which works in a slot of suitable length cut in the
moveable arm of the clipper. The revolving induction ring gives motion to the
moveable arm and causes the alternating rectilinear movement of the clipper.

page_text: I, CHARLES DE SALAZAR, 13 Arundel Street, Haymarket, London, Electrical
Engineer, 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 :-
My said Invention consists in combining with horse clippers an electro-motor
having a circular motion by means of which a reciprocating rectilinear motion is
imparted to the moveable comb of the clipper. In the following description, and
in the drawings, is described, and shown, an electro-motor which is suitable for
the said purpose, and it substantially consists of two induction rings or circular
electro-magnets one of which is fixed whilst the other is caused to revolve on an
axis by the action of the current. The revolving spindle is so connected with the
moveable comb of the scissors that a reciprocating rectilinear movement is given
to the same by the rotation of the former.
I will now proceed to describe my Invention with reference to the accompanying
drawings in which the same letters of reference indicate like parts in all the
figures. Figure 1, is a front elevation, and Figure 2, a side elevation, of a horse
clipper constructed in accordance with this invention, and Figure 3, a back elevation
of the electro-motor showing the mechanism for transmitting motion to the moveable
comb as hereinafter described. A. A¹ are respectively the moveable and stationary
combs of the clipper, B. is the handle and C. the arm connecting the stationary
comb A¹ to the handle. One of the circular electro magnets D. D' is attached at
its neutral points to the arm C. and the other is provided with a cross bar & formed
of brass, and which bar carries an axis e working in a bearing formed in the arm C.
The said axis also carries the commutator of the electro-motor. To the free end
of the axis e is attached a pinion F. having two teeth f on the inner face of its disc
(which is indented immediately over each tooth, see Figure 3,) gearing into pins
on the disc wheel G. which has a crank pin H on its face the periphery of the disc
wheel G. is provided with as many indentations as there are pins on its face, the
points between each pair of indentations are situated in the radial line midway
between each pair of teeth. It will be evident from this arrangement that the
wheel G is only free to revolve when one of the teeth f is actually operating one
of the pins on the disc wheel G-The arrangement of the pinion R, and wheel S,
Figure 5, may be employed in place of the foregoing step by step movement.
some cases the crank pin H. is directly attached to the axis e- -The said crank
pin H. gives a vibratory movement to the lever I. either by means of a connecting
rod or by working direct in the slotted end of the said lever, as shown in the
drawings. The lever I turns freely on the pin k, which is fixed firmly to the
stationary comb A' and the movement of the extremity of the upper, or shorter,
arm of the said lever gives a reciprocating movement, in the form of clipper
shown, to the comb A. by means of a pin working in a slotted hole, as will be well
understood.
In
In some cases, instead of communicating the motion from the electro-motor to
the moveable comb by the means hereinbefore described, I pivot the extremity of

page_text: one of a pair of links . l. Figure 4, to a stud on the fixed comb A¹ and the
corresponding end of the other link is arranged to work freely on the stud m. fixed
to the comb A. The opposite ends of the two links are jointed together by means
of the pin n. The links so arranged form a toggle joint and it will be readily
understood that when the pin n. is made to reciprocate in a direction at right
angles to the line passing through the centres of the studs m. the comb A has
the desired reciprocating motion given to it-Motion is communicated to the said
toggle joint from the electro-motor by any suitable and known means such as a
connecting rod from the crank pin H to the joint pin n or it will be evident that
the crank pin may be replaced by a cam.
In the cases hereinbefore described the axis of the electro-motor has been
assumed to be at right angles to the plane in which the comb A. moves, but, in
some cases, I construct the clippers with an electro-motor having its axis parallel
with the plane of the clipper, in which case the pinion F. may be replaced by a
worm gearing into a worm wheel in place of the toothed wheel G. a crank pin or
cam being fitted on the worm wheel in a similar manner to that, described in the
case of the wheels G. and S.
When the moveable comb is operated by means of the toggle joint arrangement
shown in Figure 4 it will be evident that, if the motor has its axis parallel with
the plane of the combs, the end of the armature spindle e. may be provided with a
drum T. Figure 6. having a groove cut on its cylindrical surface, the plane in
which the said groove lies being inclined to the armature axis e. In this case the
rod I. works in guides i. and is provided with a stud projecting from it at right
angles and gearing into the inclined groove on the drum T, this arrangement, as
shown in the drawing, will give one double reciprocation of the moveable comb for
each revolution of the armature and it will be readily understood that if more
than one reciprocation is required the groove on the drum T must be cut in a
wave line, the number of waves corresponding with the desired number of
reciprocations of the comb.
It will be understood that I do not wish to confine this invention to the employ-
ment of electro-motors constructed as hereinbefore described and shown in the
accompanying drawings, as any suitable electro-motor will effect the desired object
when arranged in a similar combination.
It will be readily understood that horse clippers constructed as hereinbefore
described will be found suitable for many analogous operations.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is
In the construction of horse clippers, the combination with the various parts
thereof, which are constructed substantially, in the ordinary manner, of an electro-
motor, having a circular motion, arranged in such a manner and in connection with
such means, that a reciprocating rectilinear motion is imparted to the moveable
comb of the clipper, substantially as hereinbefore described. and shown in the
accompanying drawings.
