page_text: I, HENRY HARRIS LAKE, of the firm of Haseltine. Lake & Co., Patent Agents,
Southampton Buildings, in the County of Middlesex, do hereby declare the nature
of my 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 safety razors or shaving instruments the object being
to provide an improved blade-holder and handle combined, also an improved guard
for the blade-edge, together with means for adjusting the blade, whereby the
construction and arrangement of such instruments is simplified and their cost is
reduced.

:-
This invention relates to safety razors or shaving instruments the object being
to provide an improved blade-holder and handle combined, also an improved guard
for the blade-edge, together with means for adjusting the blade, whereby the
construction and arrangement of such instruments is simplified and their cost is
reduced.

invention.

A A are jaws having sockets to receive the opposite ends of a blade D. B is a
spring-handle connecting the jaws and affording a hinge at the loop b. C is a
transverse clamp-screw provided with a suitable head on one end for turning it
and for bearing upon the outside of one jaw, while its stem passes through both
jaws to screw into the one opposite its head.

o represents a socket, there being one in each of the jaws A A; they are adapted
to receive the ends of the blade D to hold the blade rigid, and H is a guard
adapted to rest between the jaws A A and be clamped by them. In operation, the
blade D and guard H are clamped or released by the jaws A A moving on the
hinge b through the rotation of the screw C, and it is immaterial in which direction
the spring of the handle B operates, whether to distend the jaws A, A, when
released by screws C, or whether to exert a pressure upon the ends of the blade
and guard as released by said screw.
By means of the spring-jaws and screw, the blade may be, together with the
guard, quickly removed and replaced, and the jaws and spring-handle may be
formed in one piece from sheet metal.
.
In order to provide means for readily adjusting the blade to the guard, so that
as the edge of the blade is worn by use it may always be set to the proper
operative position relative to the guard, I combine with the jaws A, A, auxiliary

page_text: pieces O, O, in the form of plates having themselves the sockets o, adapted to
conform to and firmly seat the ends of the blade D, as seen in Figure 2, and
adapted to conform to and rest against the inner faces of jaws A, A, and so as to
reciprocate with said jaws as they are moved by screw C. Resting against said
jaws, screws d, d pass from the pieces O, O to the outside of the jaws through
elongated openings dd having their longer axes in the direction of movement
required to bring the edge of the blade close to the guard.
The stems of screws d, d filling the openings d', d in one direction, compels the
movement of plates O, O, with the blade D to be to or from the guard H; and
upon the guard a fine line engraved over its surface and indicating the proper
position of the blade edge, enables any one to restore the blade after honeing it,
without experimenting.
The heads of screws d, d are adapted to bind against the outer surfaces of
jaws A, A, as shown in Figure 3, to set the pieces O, O.
The stem of screw C passes through elongated openings y in plates O, O, as
shown in Figures 2 and 5, so that said screw opposes no obstacle to their
movement.
The guard H consists of a plate provided with two or more rows of per-
forations h, one row being opposite the edge of the blade and the succeeding row
being placed parallel to the first to cause the perforations thereof to come opposite
the intervals between the perforations of the adjacent row, by means of which
arrangement, all.hair which would not be forced through the first row of apertures,
passes through the next one, and the increased surface presented by the walls of
the perforations h, holds the lather from flying or dropping from the guard,
so that it is possible to use the apparatus for a longer time without being
compelled to clean it, than would be the case with the employment of the guard
in common use.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, as communicated to
me by my foreign correspondent, I declare that what I claim is:-
First. The within described improved shaving apparatus, consisting of a pair of
jaws A, A, a spring-handle B formed integral with said jaws and framing them
together, a clamp-screw C adapted to close and distend said jaws, and a blade D
and guard H adapted to be enclosed between said jaws and held by the screw C,
substantially as shown and described.
Second. The within described improvement in shaving apparatus, consisting of a
pair of jaws A, A, framed together to enclose between them a blade D and guard
therefor, in combination with auxiliary jaw-pieces O, O, provided with means for
rigidly holding the ends of a blade between them and adapted, substantially as
shown, to move over, and be adjustable upon, said jaws to carry the blade with
them, for the purpose set forth.
Third. The within described improved guard for shaving apparatus, consisting
of a plate H provided with perforations h arranged in series, as shown, with those
in one row parallel to the edge of the blade, coming opposite the intervals between
the perforations of the adjacent row, and said plate being arranged relatively to a
blade D, substantially as shown.
