I, JULES EMILE LERESCHE, of St. Julien-du-Sault (Yonne), in the Republic
of France, Manufacturer, do hereby declare the nature of this invention to be
as follows:-
This invention relates to razors having removable blades.
According to my invention I secure the blade into the groove of the blade
carrier by means of a lever mounted upon the blade-carrier and the head of
which is so arranged as to act in the manner of a cam or eccentric. This head
together with the blade carrier and the back of the blade are so formed that by
depressing the lever for fixing the blade, the said lever exercises two actions
simultaneously upon the blade, riz. on the one hand it draws the blade into the
groove and retains it there and on the other hand it pushes it longitudinally
so causing it to press strongly against the abutment formed for this purpose
in a carrier at a suitable part. Thus the blade is retained in and securely
fixed to the blade-carrier at two independent points riz at the head of the
lever and at the abutment of the carrier.
By lifting up the lever the head thereof presses against the back of the blade
and in this manner forces the same out the groove in the carrier whereby the
removing of the blade is facilitated in case it sticks or is otherwise retained
in the groove, say by rust, or through the deformation of the parts, or from
any cause whatever.
The razor comprises a blade carrier in which is arranged a removable blade
the back of which is engaged in a groove of the said carrier.
A lever is mounted in a recess formed for its reception in the back of the
blade carrier, and the end of this lever is formed as a cam and constitutes the
working part of the said lever.
In one form I provide the blade with a kind of beak at its rear end designed
to engage and to hook into an abutment of the blade carrier arranged so to
form a retaining stop. Furthermore the blade is also formed with a recess
of peculiar shape in which the head or cam of the lever engages.
In order to fix the blade in position it suffices to place it in position and then
to depress the lever when the head of the said lever acts on the recessed portion
of the blade and thereby pushes the blade rearwardly thus causing the beak to be
firmly secured in the abutment. As the recess is curved towards the front end
of the blade the latter is at the same time caused, by the action of the lever
head to turn on the beak and thereby moved fully into the groove in which
position it is securely retained owing to being engaged and strongly pressed
at the recess by the head and also at the beak in the abutment.
For detaching the blade it suffices to move the lever into its raised position.
Towards the end of this movement the head of the lever produces a strong pres-
sure upon the lower part of the recess and thus loosens the blade if need be
and causes it to leave the groove.
In the form above described the lever does not extend to the front end of the

page_text: blade carrier and the back of this latter, beyond the groove, is formed with a
solid portion forming a cross-bar or bridge-piece between the right and left
portions of the blade-carrier. The groove may however be extended to the
extremity of the blade carrier when the portion may be replaced by a screw
or pivot forming a distance piece. Again the lever may extend to the end of
the blade carrier. In this case it is preferable to form the end of the lever
somewhat like a button bent without protruding beyond the right and left hand
sides of the blade-carrier.
I would remark that the fixing of the blade by means of the head of a lever
which draws it into the groove of the blade-carrier and forces it into an abut-
ment in the blade-carrier, forms the main feature of my invention.
The form and disposition of the said abutment are however of secondary
importance. Thus it is not necessary for the abutment to be designed to retain
the blade by hooking together because the blade is drawn into and retained
in the groove of the blade carrier by the lever so that as a matter of fact the
beak may be omitted.
As to the disposition of the abutment this may be varied to a large extent,
thus the abutment may form the end of the groove so that the projecting part
of the blade is pressed into it by depressing the lever.
The lever may be inverted that is to say it may be disposed so as to move down
towards the razor handle instead of turning towards the front end of the blade.
It then acts to force the blade against an abutment arranged at a point of the
blade carrier between the lever and the end of the blade for example near the
front end of the blade carrier.
In this case the abutment may be formed by a pin which passes across the
groove in the blade carrier and with the blade engages by the side of a recess.
In a further modified arrangement the lever instead of acting direct upon
the blade may be caused to only act upon it through the intervention of a small
slide mounted in the groove of the blade carrier."
Moreover the lever may be arranged so as to move laterally that is to say,
in a plane perpendicular to that of the blade.
In these last two cases the lever acts only so as to move the blade against its
stop and to secure it in its place.

Improvements in Razors.
I, JULES EMILE LERESCIIE, of St. Julien-du-Sault (Yonne), in the Republic
of France, Manufacturer, 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 to razors having removable blades.
According to my invention I secure the blade into the groove of the blade
carrier by means of a lever mounted upon the blade-carrier and the head of
which is so arranged as to act in the manner of a cam or eccentric. This head
together with the blade-carrier and the back of the blade are so formed that by
depressing the lever for fixing the blade, the said lever exercises two actions
simultaneously upon the blade, viz. on the one hand it draws the blade into the

in a carrier at a suitable part. Thus the blade is retained and securely
fixed to the blade-carrier at two independent points viz., at the head of the
lever and at the abutment of the carrier.
By lifting up the lever the head thereof presses against the back of the blade
and in this manner forces the same out the groove in the carrier whereby the
removing of the blade is facilitated in case it sticks or is otherwise retained
in the groove, say by rust, or through the deformation of the parts, or from
any cause whatever.
My invention will be readily understood from the accompanying drawing,
in which:
Figure 1 shows a razor, partly in elevation and partly in section, constructed
in accordance with my invention, the parts being shown as they would appear
before the depression of the locking lever.
Figure 2 is a similar view but with the lever depressed and the parts firmly
locked together.
Figure 3 is a similar view to Figure 2 but showing a modified form.
Figure 4 shows the back of the razor of Figure 3.
Figures 5 and 6 show modifications.
Like letters of reference designate corresponding parts in all the figures.
a designates the blade carrier and 6 the removable blade, the back of which
is engaged in the groove c of the blade carrier.
d is the lever which is mounted in a recess e formed for its reception in the
back of the blade carrier. f is the head forming a cam and constituting the
working part of the lever.
In Figures 1 and 2 I have shown the blade provided with a small projec-
tion at its rear end adapted to engage and to hook into the abutment h of
the blade carrier so to form a retaining stop. Furthermore the back of the
blade is also formed with a recess at i j of peculiar shape in which the head f
of the lever d engages and is slightly cut away toward the rear end in order to
form the projecting part which engages into the recess e behind the head f.
In order to fix the blade in position it suffices to place it as shown at Figure 1
and then to depress the lever as indicated by the arrow 1 when the head of the
said levers acts on the portion and thereby pushes the blade in the direction
indicated by the arrow 2 thus causing the beak g to be firmly secured in the
abutment h. As the recess is curved towards the front end of the blade, the
latter is at the same time caused, by the action of the lever head f, to turn on
the point gas is indicated by the arrow 3 and thereby moved fully into the
groove as shown at Figure 2 in which position it is securely retained owing
to being engaged and strongly pressed at i by the head f and also at g in the
abutment h.
For detaching the blade b it suffices to move the lever d from the position
Figure 2 into the position Figure 1. Towards the end of this movement the
head f of the lever produces a strong pressure upon the part ; of the recess i j
and thus loosens the blade, and causes it to leave the groove c.
It will be noticed that in the form shown at Figures 1 and 2 the lever
does not extend to the front end of the blade-carrier, and the back of this latter,
beyond the groove e, is formed with a solid portion m forming a cross-bar or
bridge-piece between the right and left portions of the blade-carrier. The
groove e may however if desired be extended to the extremity of the blade
carrier, in which case the portion m may be replaced by a screw or pivot
forming a distance piece. Again the lever d may extend to the end of the
blade carrier as shown in Figures 3 and 4. In this case it is preferable to form
the end of the lever somewhat like a button n, bent but without protruding
beyond the right and left hand sides of the blade-carrier.
I would remark that the fixing of the blade 6 by means of the head f of a

page_text: lever d which draws it into the groove of the blade-carrier, and forces it into
an abutment in the blade-carrier, forms the main feature of my invention.
The form and disposition of the said abutment are however of secondary
importance. Thus it is not necessary for the abutment to be designed to retain
the blade by hooking together, because the blade is drawn into and retained in
the groove of the blade carrier by the lever, so that as a matter of fact the
projection g may if desired be omitted as shown in Figure 3.
As to the disposition of the abutment, it is obvious that this may be varied
to a large extent, for instance it may be formed as shown at k, forming the end
of the groove e, the shape being somewhat similar to that shown in Figures 1
and 2, so that the part of the blade is pressed into it by depressing the lever d.
The lever may be inverted, that is to say it may be disposed so as to move
down towards the razor handle instead of turning towards the front end of the
blade. It then acts to force the blade against an abutment arranged at a point
of the blade carrier between the lever and the end of the blade, for example
near the front end of the blade carrier.
Figure shows a convenient arrangement of this kind in which the abutment
is formed by a pin h which passes across the groove in the blade carrier and
with which the blade engages by the side q of a recess r.
In a further modified arrangement (Figure 6) the lever d instead of acting
direct upon the blade 6 may be caused to act upon it through the intervention
of a small slide o mounted in the groove of the blade carrier.
Moreover the lever may be arranged so as to move laterally, that is to say
in a plane perpendicular to that of the blade.
In these last two cases, the lever acts only so as to move the blade against
its stop and to secure it in its place.
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:—
1. In a razor having a removable blade the combination with a blade carrier
having a groove, a removable blade the back of which is engaged in the said
groove, of a lever mounted upon the blade carrier and formed with a cam head,
an abutment formed in the blade carrier and a recess in the back of the blade,
against the end of which the head of the lever acts, thus pushing and applying
the blade against the abutment and also drawing the blade into, and retaining
it in, the groove of the blade carrier substantially as hereinbefore described
and illustrated in the accompanying drawings.
2. The razors constructed substantially as herein before described and shown
by the accompanying drawings.
