page_text: We TERENCE FRANCIS CURLEY of 204 Union Street, Manufacturer, and ALBERT
SANFORD GRANGER, of 629 Douglass Street, Gentleman, both of Brooklyn, in the
County of Kings and State of New York, United States of America, 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:-
Our invention relates to safety razors, that is to say, to razors which are provided
with guards which protect the flesh from being cut when the razors are in use, and
the object of our invention is to provide such razors with guards which may be readily
reversed to allow of using either side of the razor blade, and which may be removed
to permit of the exchange of razor blades.
Our invention consists in the combination with a tubular razor back pivoted in a
handle, of a razor blade inserted in the back, and a reversible guard adapted to be
used in connection with either side of the razor blade, all as hereinafter more fully
described.
Reference is to be had to the accompanying drawings forming a part of this
specification, in which similar letters of reference indicate corresponding parts in all
the figures.
Figure 1 is a side elevation of our improved safety guard razor with a portion
broken away to more clearly show the construction. Figure 2 is a side sectional
elevation showing the guard unfastened and partly removed from the razor back.
Figure 3 is a transverse section taken on line in Figure 1. Figure 4 is a
transverse section taken on line y-y in Figure 2. Figure 5 is a transverse section
taken on line in Figure 2. Figure 6 is a side elevation of a modified form of
our improved razor. Figure 7 is an edge view of the same. Figure 8. is a transverse
section taken on line in Figure 6. Figure 9 is a side elevation partly in
section of a modified form of our improved safety guard razor. Figure 10 is a side
elevation of the removable guard. Figure 11 is a detail view of the end of the guard
and razor. Figure 12 is a side elevation partly in section of a modified form of
guard; and Figure 13 is a transverse section taken on line y-y in Figure 12:
A is the tubular back having a U-shaped shank B which is pivoted to the handle C

page_text: at a.
Upon one side of the tubular back A there is a slot b which corresponds in
position with the groove of the shank B, and to the tubular back is fitted the razor
blade D which is clipped by the edges of the slot of the tube and is retained therein
as the back of the blade is wider than the slot in the tubular back.
The guard E consists of a flat strip of metal bent at right angles at each end
forming orms cd, the arm d terminating at its extremity in an eye c adapted to fit
over the tubular back A and provided with a slot f which permits it to slip over the
back when the blade D is held in the back A. The opposite sides of the guard E are
fluted so as to form oblique transverse ribs al which contract with the sides of the
blade of the razor, allowing the beard to pass between the ribs at the same time pre-
venting the blade from cutting the flesh. The arm e of the guard E is longer than
the arm and is provided with a study which fits into the end of the tubular
back A.
F is a locking lever which prevents longitudinal movement of the guard which in
turns holds the blade. This lever F is fitted to the shank B and turns on the pivot a
and is provided with a T-shaped head, the width of the narrower portion of which
does not exceed the diameter of the tubular back A. The arm has a serrated
concave edge and a tang which extends beyond the pivot a.
In Figure 1, the guard is in the position it occupies when the razor is in use.
In order to strop the razor, the guard is turned back through a half revolution,
so that it will lie in the same plane as the razor blade but upon the opposite
side of the razor back. When it is desired to remove the razor blade D, the
locking lever F. is turned on its pivot thereby releasing the arm & of the guard E
and allowing it to be moved longitudinally along the tubular back A when the blade D
may be pushed out from the free end of the back. When the guard E is in place,
as shewn in Figure 1, the arm springs into a notch & in the end of the tubular
back A.
In the modification shewn in Figures 6, 7, and S. the guard E turns, in the same
manner as before described, upon the back A but the eye el which turns upon the
back is not slotted and the guard is provided with a lug which is engaged by a
forked latch e formed upon the end of the arm F, the said arm being placed in the
U-shaped shank B' and arranged to turn on the pivot 2, as in the other case. When
it is desired to remove the blade D', the arm . of the guard E is sprung out of
the end of the tubular back A and swung laterally so as to allow the plate D' to
..slide out.
We preferably form the beaded back of the razor blade of a slotted cylindrical rod
fastened to the back by soldering, but the beaded back may be made in one with
the blade.
In the modification shewn in Figures 9, 10, and 11, the back A which is of tubular
form, is provided with a slot for receiving the razor blade B2. The shank (2
which is formed in one with the back A is made hollow to receive the shank D² of
the guard E. The blade B fits loosely in the back A2 to permit of its being swung
laterally a short distance to place it upon one side or the other of the guard E. The
shank D of the guard E2 is pivoted in the handle F2 at which also serves as the
pivot for the shank D)². The shank D is provided with a curved slot a* for receiving
the pivotal pin 2 and the edge of the said shank D2 is provided with a curved
serrated surface to afford a firm hold to the thumb while the razor is in use. The
guard E consists of a flat strip of metal extending from the end of the shank D and.
hent at right angles, as seen in Figure 10, an arm being formed upon the free
extremity of the guard for engagement with the end of the tubular back A2, the said
arm being provided with a notch which catches upon the end of the tubular
back A².
In the modification shewn in Figures 12 and 13,
and the guard E3 is provided with a short arm f
hole 73 in the inner side of the hollow shank C³
of the guard, is provided with a stud adapted
back.A.
the pivoted shank D³ is omitted
having a lug g³ which enters a
The arm at the opposite end
to enter the end of the tubular

page_text: In Figure 9, when it is desired to reverse the guard, the arm d² is detached from the
end of the tubular back and turned on the pivot away from the edge of the blade B².
The blade B is then swung laterally in one direction or the other, as required, and
the guard E is shut down alongside the cutting edge of the blade and the notched
arm is brought into engagement with the end of the tubular back A². When
desirable, the guard E may be removed from the shank C by disengaging the slotted
end thereof from the pivot b³.
In the modification shewn in Figures 12 and 13, the blade B³ is shifted, after
swinging out the arm d³ sufficiently to release the stud in the end of the tubular
back A3, when the guard E may be swung outward and removed from the tubular
shank C3. The razor may then be swung over and the guard replaced.
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. The combination, with the slotted tubular back A., provided with the hollow
shank B, of the razor blade D, held by the tubular back, the swinging guard E,.
provided with the slotted eye c, and having the stud g and locking lever F, provided
with the T-shaped head h, substantially as specified.
2. In a safety razor, a reversible guard E, provided with transverse ribs ¹, upon
opposite sides, substantially as specified.
3. In a safety razor, the combination, with the slotted tubular back A, and the
razor blade D, held by the said tubular back, of a swinging guard E, provided with
transverse ribs a¹, and a fastener for holding the guard in the position of use, sub-
stantially as specified.
4. In a safety razor, the combination, with the slotted tubular back, and the blade
loosely fitted to the said back, of a guard having one of its ends inserted in the tubular
shank of the back, and having the opposite end removably secured to the end of the
tubular razor back, substantially as specified.
5. The combination, with the slotted tubular back A, provided with the tubular
shank C, of the blade B2, and the guard E2, provided with the shank D2, pivoted in
the tubular shank C, substantially as specified.
