of the user and which guard has housed a gen
erally reciprocable type of blade. This blade has
embraced a large number of teeth or projections,
it the side edges of whichwere sharpened. The
guard has similarly included a large number of
spaced elements, each having sharpened edges`
which cooperated with the edges of the blade
projections, so that as the blade was reciprocated
within the guard a shearing action would occur..
Various forms of this apparatus have appeared
upon the market, and it has been customary to
mount the guard and blade assembly upon a head
portion coupled to `a handle. The latter has been
hollow and has enclosed a motor which, when
energized, has served to reciprocate the blade or
otherwise suitably move the same with respect to
the guard.
Aside from other objections, one major diñ'ì
30 culty which has been present in an apparatus of
this nature has „been that the user, in pressing
Áthe guard against the skin, has caused the skin
to wrinkle under the guard, as a consequence of
which the hair or whiskers have tended to as
sume positions parallel to the skin surface. -As a
With these and other objects in mind, refer

lustrated in Figs. 6 and '1. In these views a
mechanism similar to that aforedescribed is
presented. However, a pin 46" is associated with
the lhousing 24 and rides within a groove 46 50
formed in the blade body 21. Accordingly, the

so that the shearing structure may cooperate to
maximum advantage with the hair to be re

bore 26 may be closed by a cap 36, which latter
55 may be removed for the >purpose of permitting
a discharge of any matter accumulated within
such bore, and especially within the hollow por
tion of the blade body.
It is one of the primary objects of the present
invention to assure a maximum of coaction be
tween the shaving implement and the surface
which is to be cleaned. To this end, it is pro
posed to tension 'such surface. While-within
the purview of the present invention-struc
65 tures may be devised which extend adjacent the
shearing zone and which will not be power Ádriven
to effect this result, it is preferred that a power
driven mechanism be employed. To this end,
as shown especially in Figs. 2 and 5, the plate
70 _31 may mount a shaft 31, which extends beyond
the housing 24. At this point the shaft supports
' a worm 33.
Extending adjacent the worm, and
exterior-ly of the housing, .is a shaft 33, which
1 mounts at its lower end a gear 43, to be driven
by the worm 33. Adjacent its upper end, 'shaft

the latter to merely reciprocate.
Now referring to the form of construction; illus 55
trated in Figs. 8 to 1l, it will be observed that
there is illustrated a shaving apparatus which
is of especial utility for use in removing hair
from inaccessible surfaces such as from under
the arm-pits and other concave surfaces. To 60
this end, the operating surface of the razor pre
sents an outer configuration corresponding to a
fragment of a sphere. As illustrated, it includes
a guard 5I in the form of a convex body, and
-one edge portion of which is preferably shaped to 65
provide a comb portion 62, the teeth edges of
which 4are sharpened to present shearing sur
faces. 'I'his body may have a central stud 63,
which serves to movably mount a blade 66 in
spaced relationship to the guard 6I. This blade, 70
as especially shown in Fig. 11, has teeth 66, the
side edges of which are sharpened or beveled to
cooperate to maximum advantage with the ad
jacent surfaces of. the comb projections. The
blade may be formed with a central opening 75
Vwithin which the bosses 53 project, as well as
openings 51 spaced from the central opening andÁ
through which fastening elements such as screws
~ 58 may extend. The blade is also-formed with
an opening 58 within which `a pin 59 rides. - VThis

in Figs. 16 and 1'1, it will be noted that in-this

though it will be equally apparent that rollers

of the vrollers a double guard yand cutting mecha
nisrn has been employed,- and these guards may be
arranged in tangential planes so as to cooperate
to best advantage with the surface to be shaved.
In these views, the numeral 88 indicates a drive 20

circular path. This pin rides- in a groove corre

alone to protect the shearing edge of the blade
but also functions to maintain the blade against
accidental displacement.
