Improvements in Hair Clippers.
We, GEORGE FRANKLIN STEVENS and FRED EUGENE STEVENS, both of
No. 161 Washington Street, Haverhill, in the County of Essex and State of
Massachusetts, United States of America, Gentlemen, 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 has for its object to provide a hair clipper in which the handles:
can be adjusted at any desired angle with reference to the toothed cutting plates or
blades, so that the clipper can be adapted for convenient operation on various parts
of the body of an animal, some parts being more conveniently reached when the
handles stand in a position approximately at right angles with the plane of said.
blades, while other parts are more conveniently operated on when the handles stand
approximately in line with the plane of said blades. The invention consists in a.
hair clipper comprising the construction substantially as hereinafter described and
claimed.
Of the accompanying drawings, forming a part of this Specification,―
Figure 1 represents a top view of a hair clipper embodying the invention.
Figure 2 represents a side view of the same."
Figures 3 and 4 represent top views, showing different ways of carrying the
invention into practice.
Figure 5 represents a side view of the construction shown in Figure 4.
Figure 6 represents a section on line 6-6, Figure 4.
The same letters of reference indicate the same parts in all the figures. In the
drawings
a a' represent the toothed plates or blades of a hair clipper, said blades having
the usual comb-shaped cutting edges and being pressed together so that one is in
rubbing contact with the other. This invention has nothing to do with the
construction of the blades and with the manner of connecting and operating them,
but relates wholly to the hereinafter described adjustable connection of the
operating handles 6 6¹ to the blades.
In carrying out the invention, we provide the blade a with a cylindrical stud or
bearing c, and the blade a¹ with a cylindrical stud or bearing c¹, said studs being
formed on or attached rigidly to the blades in any suitable manner. In the
handles 66 we form sockets adapted to closely fit and turn upon said studs, the
handles being formed as separate parts movable on the studs. The studs are so
arranged that when the handles are placed upon them said handles can swing in
planes substantially at right angles with the plane of the blades, so that each
handle can occupy a position approximately at a right angle with the plane of the
blades, as shown at x (Figure 5), or a position approximately parallel with said
plane, as shown at x, or in various intermediate positions more or less inclined, as
shown in full lines in Figures 2 and 5.
It will be seen that this provision for the adjustment of the handles relatively to
the cutting blades greatly increases the usefulness and convenience of the clipper,
particularly when used for horse clipping. It is also convenient and desirable in
clippers for cutting human hair.
The handles may be held by friction in any position to which they may be
adjusted, or if preferred, by positive means. When the studs c c are slightly
tapered, as shown in Figures 1 and 4 (the sockets in the handles being correspondingly
tapered), a sufficiently firm connection can be secured by friction alone. The same

page_text: result may be attained without tapering studs by providing springs e e (Figure 3)
arranged to press the handles outwardly against washers ff secured by screws ff
to the studs.
In Figures 2, 4, 5, and 6, we show the handles provided with locking pins i pressed
by springs into engagement with holes in the studs, there being a series of said
holes, so that the handles may be locked in several positions.
Various other modifications may be employed without departing from the spirit
of our invention, which is not limited to the details here shown.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is:
1. In a hair clipper, the combination with two toothed plates or blades one
movable upon the other and having journals the axes of which are substantially
parallel with the front edges of said toothed plates, of handles connected with said
journals, and means for holding the handles in varying positions ranging from a
substantially straight line with the plane of the blades to an approximately right
angular position relatively thereto.
2. In a hair clipper, the combination with two toothed plates or blades one
movable upon the other, and a cylindrical stud or bearing connected with each of
said blades and having its axis substantially parallel with the front edge or line of
the teeth of handles having sockets fitting said studs and adapted to stand
thereon at different inclinations relatively to the blades, and means for holding the
handles in their adjusted positions.
:
3. In a hair clipper, the combination with two toothed plates or blades, one
movable upon the other, and handles for operating said blades: of means for
frictionally holding the handles in varying positions relatively to the blades,
ranging from a substantially straight line with the plane of the blades to an
approximately right angular position relatively thereto, said means including
hinge-members on the blades the axes of which are substantially parallel with
said toothed plates, and hinge-members on the handles engaged with members on
the blades.
