Improvements in Safety Razors.
I, BENJAMIN JOSEPH BARNARD MILLS carrying on business under the firm or style
of Harris and Mills of 23 Southampton Buildings in the County of Middlesex, Patent
Agent, do hereby declare the nature of this invention, a communication to me from
abroad by Albert S. Aloe of the City of St. Louis, in the State of Missouri, one of
the United States of America, Merchant, to be as follows:-
In this improvement, the guard roller is made with spiral ribs so as to carry the
lather, &c. endwise as it is turned by its bearing against the skin. The clamps
upon the clamp plate are made to cover the points of the blade and thus act as guides
therefor.
The main plate of the case has a handle to which it is hinged, and a spring catch
plate is hinged to the main plate and handle. A clamp plate is connected to the
main plate by hinges, the ears of these hinges forming projections against which
the ends of the blade bear. At the corners of the clamp plate are hooks which engage
the edge of the blade at the corners. Ears upon the clamp plate give journal bearing
to the guard roller. The guard roller is made with spiral rib or ribs, which extend
from end to end of the roller, and which act to carry the leather, &c. endwise, as
the roller is turned by pressure against the skin. The inclination or pitch and the
number of the spiral ribs may be varied or a single spiral rib would answer the
purpose, if the pitch were made sufficiently low.
The spring plate has a spring tongue extending back of the hinge, so as to hold
the front end of the plate down upon the blade.
The spring plate is split and bent at its front part, so as to form fingers that extend
over the blade, fingers that hook over the top of the clamp plate, and a finger that
fits behind the clamp plate. These fingers hold the clamp plate and blade in using
position. By disengaging these fingers from the clamp plate, the blade can be
removed and the parts folded, to be put, if desired, in a case,

page_text: A holder made in two parts, is employed; the one part is made hollow to
receive the other or solid part, and has a slot in its back through which extends
a pin in the solid part. When the solid part is extended it receives the blade,
and the device acts as a holder for use in sharpening the blade. When the blade is
removed, the solid part can be telescoped into the hollow part, when it may, if :
desired, be placed in a suitable case.

page_text: Figure 5 is a detail end view.
Figure 6 is a detail cross section, showing the position of the blade relative to the
clamp plate and guard roller, the section being taken on line 6-6, figure 4.
Figures 7 and 8 illustrate a device for holding the blade in sharpening it; figure 7
showing the holder open and the blade in place, and figure showing the holder
closed up.
In this improvement, the guard roller is made with spiral ribs, so as to carry the
lather, &c., end wise as it is turned by its bearing against the skin. The clamps
upon the clamp plate are made to cover the points of the blade and thus act as guides
therefor.
A is the main plate of the case having a handle a, to which it is hinged at a¹. Bis
the spring catch plate hinged to the plate A and handle a at a¹. Cis the clamp
plate connected to the plate A by hinges a², the ears of these hinges forming pro-
jections against which the ends of the blade D bear (see figure 3). At the corners

of the plate Care hooks c, which engage the edge of the blade at the corners.
ears upon the plate C giving journal bearing to the roller E. The roller is made with
spiral rib or ribs e, three being shown, which extend from end to end of the roller,
and which act to carry the lather, &c., end wise, as the roller is turned by pressure
against the skin. The inclination or pitch and the number of the spiral ribs be
varied. It will be seen that a single spiral rib would answer the purpose, if the pitch
were made sufficiently low.
inay
The spring plate B has a spring tongue 6 extending back of the hinge a¹, and
bearing upon the plate A, so as to hoid the front end of the plate B down upon the
blade.
The plate B is split and bent at its front part, so as to form fingers b² that extend
over the blade, fingers that hook over the top of the plate C, and a finger b' that
fits behind the plate C. These fingers hold the plate C and blade in using position.
By disengaging these fingers from the plate C, the blade can be removed and the
parts folded, as shown in figure 3, to be put, if desired, in a case.

page_text: I represents a holder made in two parts, I¹ and I2; the part I¹ is made hollow to
receive the part I, and has a slot 13 in its back, as shown, through which extends a
pin J in the part I². When the part I is extended, (as shown in figure 7), it receives
the blade and the device acts as a holder for use in sharpening the blade. When the
blade is removed, the part. I can be telescoped into the part I (as shown in figure 8),
when it may, if desired, be placed in a suitable case.
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. A safety razor having a guard roller provided with a spiral rib, substantially as
set forth.
2. The combination of a razor blade and a plate, to which the blade is clamped,
said plate having hooks forming guards for the corners of the blade, substantially as
set forth.
3. The combination of the plate A, having plates B and C hinged to it, the plate B
inade with tongue b, and part with fingers 3, 3, 4, and the plate Chaving 'hooks c
and hinges a², the hooks engaging the edge of the blade.
4. The combination of the plate A, a razor blade D and a plate connected to the
plate A by hinges a² formed by projections on the plates A and C, and the plate C
having hooks c, substantially as, and for the purpose, set forth.
5. The combination, with the plate and the plate C hinged thereto, of the latch
plate B, hinged to the plate A and having the lips or fingers embracing the edge of
the plate C between them, as set forth.
6. The combination, with the plate A, the blade plate Chinged thereto, and the
blade D of the plate B, hinged to the plate A and engaging directly with the blade
plate C, and the lugs or fingers 2 projecting from the plate B and engaging the
blade 1 for holding it to place, substantially as set forth.
7. In a safety razor, a device for holding the blade while sharpening it, consisting
of two members, one of which serves as the handle, and the other of which acts to
receive the blade, the latter telescoping the former, substantially as set forth.
8. In a safety razor, a device for holding the blade while being sharpened, con-
sisting of a handle part slotted on its back, a holder part telescoping the handle part,
and a moving pin secured to the holder part and extending through the slot in the
handle part, substantially as shown and described.
