I, FRANK LAWRENCE of the city of St. Louis in the State of Missouri in the
United States of America, but at present residing at the Hotel Metropole, Charing
Cross in the county of Middlesex Gentleman 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 reference being had to
the accompanying drawings forming part of this specification and in which:
Figure 1 is a perspective view of my improved razor.
Figure 2 is a perspective view of the blade supporting plate.

3 is a perspective view of the handle removed.
4 is a perspective view of the blade-dog removed from the handle.
Figure 5 is a perspective view of the blade-holder for use in sharpening the blade.
Figure 6 is a similar view, showing the blade in place in the holder, and the holder
secured to the handle.
Figure 7 is an enlarged detail perspective view of the blade supporting plate.
Figure 8 is a similar view slightly modified, and
Figure 9 is a similar view, showing still another modification.
This invention relates to certain improvements in safety razors, and consists in
features of novelty hereinafter fully described and pointed out in the claims.
Referring to the drawings, A represents the blade, supported by a plate B, to which
it is held by end lugs or projections C on the plate, that grasp the ends of the blade,
as shown in figure 1. These projections are prefarably slit or cut, at D, which
disconnects them from the plate B, at these points, and only leaves them united to the
plate for a short distance, at E. The object of these cuts is to allow for the adjustment
of the blade relative to the guard roller, as it becomes worn. Thus, when the blade
is put in, it will be held by the stop C, at the proper place, and as it becomes worn,
the stops will yield, owing to the cuts D, to pressure brought to bear upon the blade
and allow the latter to be forced down farther to bring its cutting edge in the proper
relation to the guard roller.

page_text: In figures 1, 2 and 7 I have shown the cuts D between the stop lugs and the plate B.
In figure I have shown the upper cut D at this point, and the lower cut at the outor
corner of the stop shown in this figure. In figure 9, the modification that is shown
consists in placing the stops at an incline to the plane of the plate B, which will yield
outward, when pressure is brought to bear on the blade, and allow the downward
adjustment of the latter.
F represents the guard-roller, which is provided with a number of circumferential
grooves forming a series of annular rings, which assist in the use of the instrument
by moving the latter and depressing the skin, at intervals.
G represents the handle, which is secured to the blade and the supporting plate, in
a cheap and novel method. H represents a dog threaded to enter a socket in one
end of the handle G. This dog has a non-circular portion I between its head and the
screw H¹, which fits between lugs B' extending upward from the plate B, and against
one side of which an enlarged end G2 of the handle G bears, as shown in figure 1.
The dog engages the blade, as shown in figure 1, and it will be understood that,
when the dog is placed over the blade, with the neck I between the projections B¹, and
the handle screwed up tight against the projections, the blade and handle will be held,
firmly connected to the plate B. When it is desired to disconnect the parts and
remove the blade, it is only necessary to unscrew the handlo slightly when it (carrying
the dog with it) can be moved upward away from the blade and its supporting plate,
and the blade is then free to be moved from the plate. This method of connecting
the blade to the supporting plate is simple, durable and cheap, and is effective in
holding the parts together.
L represents the holder in which the blade is placed, as shown in figure 6, to be
sharpened. This is provided with a threaded neck L', which may be screwed into the
socket G of the handle G, by removing the dog H.
When the holder. L is not in use it may be inserted into the hollow handle from
the rear end, the threaded neck L', projecting from the handle as shown in figure 3.
Having now particularly described and ascertained the nature of this invention and
in what manner the saine is to be performed I declare that what I claim is :-
1. In a safety razor, the plate B provided with lugs or projections C, having slits
or cuts D, substantially as and for the purpose set forth.
2. In a safety razor in combination with the plate B having projections B³, the
handle G and dog H substantially as and for the purpose set forth.
3. In a safety razor in combination with the plate B, having projections B¹, the
handle G having a serew threaded socket G and dog H having non-circular shoulder I
and threaded outer portion H' substantially as set forth.
4. In a safety razor, in combination with the blade supporting plate, a guard roller
journalled to the plate, and having a series of circumferential grooves substantially
as set forth.
