?lm-like leaves or shavings‘which dissolve in
stantly upon contact with the wet hands of the
A further object of the invention
to provide
a simple and e?icient means to remove from
any preferred soap bar the said eiiective usage
quantities of soap, said means being adapted to
embodiments in Various forms and designs ap
propriate to the locations in which they are to be
I--* used as wall ?xtures and further adapted to
portable forms of small size for the traveling kit.
Another object of the invention is to provide
a means for economically dispensing any selected
kind of bar soap in a rapidly soluble form and in
a cleanly fashion, and whereby the unsightly
soap dish is replaced by an attractive ?xture
which is capable of embodiment in many different
shapes and designs.
These and other objects are attained by the
means described herein and disclosed in the
accompanying drawings, in which:

Soap in bar form remains the most satisfac
tory form of cleansing agent that is universally
used in the civilized world, although it is in some
ways wasteful and productive of unsightly con
ditions about the places in which it is used.
Soap in liquid, powdered and other forms has
found no universal acceptance by the public be
cause of inherent objections to the character and
quality of the materials and because the results
secured therefrom by the average user are less
satisfactory than from soap in cake or bar form.
It has been proposed heretofore to remove thin
slices and granular particles from bars of soap
by mechanical means but the means employed
55 have not been extensively used because of di?i~
culty in actual operation or dependency on at
mospheric conditions.
The present invention avoids all heretofore
known objections to soap dispensers and opens up
a further ?eld for such devices in the home and in >
fact in any places where soap is used non-indus
trially or where rapid dissolution of soap is re
quired in any quantity.
The wall mounting type of dispenser of the in
vention may desirably be of the arrangement i 150
shown in the drawings since this form is readily
adapted to manufacture both as a high grade
?xture and as'relatively inexpensive forms of dis
penser. It is furthermore- well adapted to a large
variety of ornamental designs and may be made‘ 7
from a variety of materials suitable in appear
ance and price for different uses and markets.
The mechanism itself distinguishes essentially
from heretofore known devices in the means and
method of removing a de?nitely controlled
amount of soap from a selected bar, in a form
that is at once free from scattering and waste and
that dissolves completely and instantly as it falls
upon the wetted palm of the user’s hand or on any
thoroughly wet surface.
While the device in its I
several forms is adapted to the use of bar soaps
of various kinds in the slightly moist condition
in which they are ordinarily purchased and used,
the drying out of the bar does not result in a less
effective form of the material dispensed. More
speci?cally, a somewhat moist cake of soap will
be dispensed in soft thin leaf~like shavings or
?lms while an unusually dry cake of soap will
produce a less cohesive dispensed product that is
practically of the same useful characteristics as
the former. The thickness of the amount re
moved from the'cake of soap is preferably of the
order of a few thousandths of an inch (e. g. .002’.’
to possibly .005”). The ready solubility of the
shavings disappears as the thickness thereof in
creases and for this reason, and also in order to
discourage waste of soap by too frequent opera
tion of the dispenser, the negative rake shaving
blade is arranged in a very de?nite relation to
the limit of movement of the bar of soap operated
Ordinary means for cutting and scraping soap
from the bar have been accompanied by either a
frequent complete jamming of the cutter or an
irregular gouging and chattering operation which
produces Wide variation in thickness of the re
moved portion and hence the production of a
relatively large amount of material that is not
easily soluble and that is objectionable not only
as to wastefulness but as a pasty solid that
gathers about the use-r’s ?ngernails.
In the several embodiments of the present in
vention, the controlled production of. soap shav
Cl ing is effected by the use of a shaving blade that
is perpendicular to the face of the bar of soap
operated upon. This blade has a negative angle
of rake on each side thereof so that it is oper
ative upon movement in either direction, whether
10 the blade be used for reciprocatory or rotary
movement in either direction. For practical
purposes it is deemed preferable to make the
blade of substantially triangular cross section
with an included angle between the negative rake
15 faces of about 45° or probably less.
The means
carrying this blade preferably represents the
limit of soap feeding movement and the scraping
or shaving edge is above it by the several thou
sandths of. an inch necessary to push said edge
20 a suitable distance into the soap. Having ?xed
relations between the soap and
means for holding and feeding the
effecting the relative movement

several forms.

A desirable form of the device as a wall
mounted ?xture is shown in Figs. 1 to 6 wherein
a substantially box-shaped frame Iii having out
wardly oifset portions H in the sides 12 thereof
30 is adapted to be secured to a wall !3 by means
of screws M passing through back wall IS.
resilient bump-er it‘ is provided near the bottom
of said back wall to absorb the shock and deaden
the metallic noise of a cutter slide ll which is
35 provided at opposite sides with .guideway mem
bers l8 riding on the outwardly turned ?anges IQ
of an inner frame 20. Springs 2| anchored to
said guideway member and said back wall l5
yieldably hold the cutter slide in retracted posi
40 tion against the bumper. The tension of these
springs is su?icient to permit ready withdrawal
of, the slide by the pull of an operator’s ?ngers
on the depending pull-?ange 22 in a natural
manner which leaves the open palm of the user’s
hand in position to receive the soap shavings as
they are removed from the bar of soap 23 above.
The slide 3'! is provided with one or more
transverse apertures 2‘; which are crossed by the
double negative rake shaving blades 25 which
50 have the top edges extending a few thousandths
of an inch above the top face of cutter slide I?
in a manner heretofore explained.
(This is
shown in exaggerated relation in Fig. 4 for the
sake-of clarity of disclosure.)
The inner frame, bounded by pairs of walls 20
and 26 is open at both ends, the topsof the walls
25 having slots 2'? therein through which the
ends of a pivoted latch 28 may extend for re
movably securing a spring urged soap feed
plunger assembly which operates on the soap bar
23 in the soap bar adapter 29 and holding the
soap 23 against the top face of cutter slide ll
and against shaving blades 25.
The adapter 29 for an otherwise standardized
65 machine is substantially a hollow sleeve of any
suitable material and of a cross sectional open
ing such that a bar of soap of given cross sec
tional shape may be used therein and held against
lateral movement while guidedly advanced by the
plunger 38. The adapter slidably ?ts in the
inner frame. Plunger 3% of the soap feed assem
bly is supported on the sides of. its slotted cylin
der 3! which houses spring 3!!) between its
closed upper end and said piston 30. Lugs 32
struckfrom the ends of slotted cylinder 3| hold
the plunger 30 against movement beyond the end
thereof. The notches 33 occasioned by the
formation of said lugs 32 and also the adapter 29
seat in place on lugs 34 on the bottom of inner
frame 26 holding the bottom open end of the
adapter slightly above the path of cutter bars 25.
Latch bar 28 holds the entire assembly secure.
The bar of soap 23 of rectangular, oval or other
cross section rests on the top of cutter slide l7
and guides at its side edges, either wholly or in 10
part on the adapter walls that are opposite the
slots in the cylinder 3|. The legs 35 of the cylin
der straddle the soap 23.
The entire device is adapted to be enclosed by
a cover shown fragmentally at 36 in Fig. 1 and 15
which may take any ornamental shape and may
be ?nished in any desired fashion.
The cover
leaves exposed only those parts shown in the
bottom plan view (Fig. 3).
Rubber bumpers 31 mounted conveniently 20
serve to cushion the forward pull on member 22
during operation of the device. To ?ll the dis
penser, the ornamental cover is slidably removed,
whereupon latch bar 28 is turned about its pivotal
mounting on stud 39 to release its ends from the 25
slots 21. The spring 32 which was held under
compression by said latch bar now pushes the
soap feed assembly (shown in Fig. 6) upwardly
so that it is easily lifted out to permit a bar of
soap 23, of the proper cross section, to be dropped 30
into the adapter 29. The feed assembly is then
replaced and the end of plunger 30 engages the
upper end of the soap 23. By pushing down on
latch bar 28 until it reaches the level of slots 2'!
and then turning it until the ends engage in the
slots, the device is conditioned for replacement of
the cover 36 and is ready for operation.
To operate the device, the user, after wetting
the hands, reaches under the device with one
hand and places the upturned ?ngertips behind 40
pull ?ange 22. Pulling forwardly against the
moderate resistance of springs 21 the cutter slide
is drawn forwardly and the blade or blades 25
shave a very thin creped appearing leaf of soap
which drops through apertures 24 into the wet 45
palm of the hand. The springs 25 provide the
return cutting movement of slide I7 and a further
scraping of soap is delivered to the palm of the
hand. The movement is rapid and easy and is
repeated once or twice to deliver the desired
quantity of soap. The thin, creped form of the 50
soap produces practically instant
thereof on the wet hands and enables rapid pro~
duction of lather such as is obtainable particu
iarly from the bar of soap used and does not
appear to be considered obtainable from liquid
or powdered soaps.
It is to be understood that while certain non
corrodible metals are deemed proper for the de
vice, it is also contemplated that vitreous mate 60
rials or materials ?nished with vitreous coatings
may be used, and also that transparent materials
may be used in parts, according to known meth
ods of fabricating those materials into devices,
where observation of the soap supply and/or of
the operation of the mechanismis desirable.
In Fig. '7 there is illustrated a rotary form of
the device which in this instance is made in small
form suitable for the traveling bag in lieu of the
personal soap box or container. It is to be under
stood that the device on a larger scale may also
be adapted to wall mounting for rotary operation.
This devicecomprises a relatively deep cover 46
preferably cylindrical and having corrugations 4|
inthe circumference thereof. The cover 40 has
an internal annular shoulder or flange 42 with a
multiplicity of yieldable bosses 43 that cooperate
with an internal ring 44 on the inner wall of a
base 45 to provide removable connection of the
cover and base and also permit easy relative ro
tation thereof.
The base 45 is apertured and has
a shaving blade 46 mounted across the opening
therein, said blade 46 being essentially like the
blades 25 of Fig. 4. The cover has a rectangular
way therein receiving a small rectangular piece
of soap 41 and the sides 48 of said way have op
and presenting a continuous straight cutting edge
slightly above the plane of the plate and to the
advancing face of the soap said blade having
clearance faces on opposite sides of said cutting
edge and forming between them an included angle
which is bisected by a perpendicular from the
plane of the plate through the straight edge.

bination of means arranged to receive a bar of
solid soap and to yieldably urge said bar endwise 10
in a given direction, an apertured plate reciproca
form a means to accommodate slight variations
ble in a plane perpendicular to the direction of
movement of the soap, a rigid wedge shape
scraper blade rigidly secured to the plate and ex
tending across the aperture in said plate, said
blade having a continuous straight edge and
clearance faces diverging from said edge on op

To ?ll this device the cover and base are
dicular from the plane of the plate through the

upright with one hand and the cover is given a
rotary or oscillatory movement with the other.
The single negative rake scraper 46 cuts in either
direction about the theoretical axes of the cylin
drical device.
