Improvements in Razors.
I, FÉLIX GEORGET, Manufacturer, of Nogent, Haute Marne, France, do hereby
declare the nature of this invention to be as follows:-
My invention relates to a system of razors the removable blade of which can be
taken off and replaced by another without the aid of any tool.
For this purpose each of the blades is provided on its back with a lug or pro-
jection having an inclined groove and which can enter a mortice in the blade-
carrier, the latter carrying a slide the end of which can engage the groove so as
to act as a wedge for firmly securing the blade to the blade-carrier.
The slide itself is preferably mounted so that it can be easily removed for clean-
ing, also without the aid of any tool.
The removable blade is provided on the back with a lug or projection in which
an inclined groove is formed.
The blade-carrier is formed with a longitudinal groove, in which the back of
the blade fits exactly. The blade carrier has a mortice formed in it for the pass-
age of the lug or projection on the blade. On the back of the blade-carrier and
behind the mortice is mounted a slide. It is provided at its rearward extremity
with an actuating knob, and at front it takes the form of a fork the two branches
of which pass to the left and right of the lug or projection on the blade.
The part of the slide which connects the two branches of the fork is on its top
side inclined in such a way that, when the slide is pushed forward, this part,
which then engages with the inclined groove in the lug of the blade, acts as a
wedge in such groove so as to tighten and securely hold the blade against the
bottom of the groove of the blade-carrier.
It will be seen that it is only necessary to draw the slide back in the opposite
direction in order to detach the blade.
I have already stated that the slide itself can be easily removed without the
aid of any tool. For this purpose, it is connected to the back of the blade-carrier
by the head of a screw screwing into the blade-carrier and passing through a long
slot in the slide. This slot is equal in width to the diameter of the stem of the
screw, but it terminates at its rear end in a circular enlargement the diameter of
which is slightly greater than that of the head of the screw.
If, after having removed the blade, it is desired to detach the slide, it is only
necessary to push it forward to the full extent so as to bring the enlarged part
of the slot opposite the screw, when it can be removed without trouble from the
blade-carrier.
It will be readily understood that razors constructed according to my system
may be made in any desired form and of any dimensions.

I, FÉLIX GEORGET, Manufacturer, of Nogent, Haute Marne, France, do hereby
declare the nature of this invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
My invention relates to a system of razors the blade of which can be taken
off and replaced by another without the aid of any tool.
For this purpose each of the blades is provided on its back with a lug or pro-
jection having an inclined groove and which can enter a mortice in the blade-
carrier, the latter carrying a slide the end of which can engage the groove so as
to act as a wedge for firmly securing the blade to the blade-carrier.
The slide itself is preferably mounted so that it can be easily removed for clean-
ing, also without the aid of any tool.
The accompanying drawing illustrates the invention.
Fig. 1 shows a razor made according to my invention on an enlarged scale, the
handle being broken off so as to save space. In this figure the removable blade
is shown in elevation and the blade-carrier as well as the fixing slide are shown
in longitudinal section.
Fig. 2 is a view of the back of the instrument corresponding to Fig. 1.
Fig. 3 is a detail view of the slide on a still larger scale.
In these figs. A represents the removable blade; it will be seen that it is pro-
vided on the back with a lug or projection a in which an inclined groove a¹ is
formed.
B represents the blade-carrier which is formed with a longitudinal groove b,
in which the back of the blade fits exactly. The blade-carrier has a mortice 6¹
formed in it for the passage of the lug or projection a. On the back of the blade-
carrier and behind the mortice is mounted the slide C. It is provided at its rear-
ward extremity with an actuating knob, and at front it takes the form of a fork
the two branches of which pass to the left and right of the lug or projection a.
The part of the slide which connects the two branches of the fork is on its
top side inclined in such a way that, when the slide is pushed in the direction of
the arrow, this part, which then engages with the inclined groove a¹, acts as a
wedge in such groove so as to tighten and securely hold the blade against the
bottom of the groove of the blade-carrier.
It will be seen that it is only necessary to draw the slide back in the opposite
direction to the arrow in order to detach the blade.
I have already stated that the slide itself can be easily removed without the
aid of any tool. For this purpose, it is connected to the back of the blade-carrier
by the head of a screw D screwing into the blade-carrier and passing through a
long slot in the slide. This slot is equal in width to the diameter of the stem of
the screw, but it terminates at its rear end in a circular enlargement the diameter
of which is slightly greater than that of the head of the screw.
If, after having removed the blade, it is desired to detach the slide, it is only
necessary to push it forward to the full extent in the direction of the arrow so as
to bring the enlarged part of the slot opposite the screw, when it can be removed
without trouble from the blade-carrier.
It will be readily understood that razors constructed according to my system
may be made in any desired form and of any dimensions.

page_text: 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 razors with removable blades, fixing the blade to the blade-carrier by
means of a lug or projection provided with a groove and formed on the blade
and of a slide acting as a wedge and movable along the back of the blade-carrier.
2. In the method of fixing the blades of razors set forth in the preceding claim,
the special arrangement permitting the slide to be detached from the blade-carrier
without the aid of any tool, such arrangement consisting in fixing the slide to the
back of the blade-carrier by means of a screw passing through a slot in the form
of a button-hole made in the slide.
3. The improved razor with removable blade substantially as described and
as shown in the accompanying drawings.
