(Cl. 248—224)
This invention is a demountable wall ?ange
adapted to be associated with and form a support
for bathroom ?xtures, and more particularly soap
and the soap dish is shown in fragmental section.
Figure 3 is a view similar to Figure 2, but show
ing the next two steps in the operation of assem
dishes, tumbler holders, towel bars, toilet paper
bling the front plate and the back plate to bring
these parts into ?nal interlocked relation.
Figure 4 is a back View of the construction

5 holders, etc.
The object of the invention is to provide an
economical and e?icient construction wherein
such ?xtures may be mounted in readily detach
able position upon a wall by means of screws or
10 nails which are normally concealed from view.
Speaking generally, the wall ?ange of the pres
ent invention comprises two plates, hereinafter
referred to as a back plate and a front plate.
The back plate is adapted to be mounted on a
15 wall by screws or nails passed through perfora
tions provided in the plate and preferably coun
tersunk, so that the back plate can be rigidly
and permanently secured in position. The back
plate is provided with openings and bridging
20 said openings is a leaf spring positioned against
the back face of said plate. The front plate has
rearwardly extending hooks arranged in pairs
with the hooks of each pair extending in oppo
site directions and so located that, when the
25' hooks are passed through the openings in the
back plate, they may be brought into clamping
relation between the spring and the distant ends
of the openings and thus be resiliently engaged
with the back plate in such manner as to pre
30 clude inadvertent disengagement of the parts
but to permit the front plate to be readily de
mounted when desired.
The ?xture to be sup
ported by the ?ange construction described is
permanently associated with the front plate.
Marked advantages of the present invention
reside in the simplicity of its construction, its
economy of manufacture and thorough practica
bility in use.

Features of the invention, other than those
adverted to, will be apparent from the herein
after detailed description and claims, when read
in conjunction with the accompanying drawings.
The accompanying drawings illustrate one
practical embodiment of the invention, but the
45 construction therein shown is to be understood
as illustrative, only, and not as de?ning the limits
of the invention.
Figure 1 is a perspective view showing the
present invention associated with a soap dish and
with the front plate removed from the back
plate.
Figure 2
is
a vertical transverse section
through the back plate showing the ?rst step in
the operation of mounting the front plate there
551 on. In this view the plate is shown in elevation
Figure 5 is a section through the back plate on 'i -
the line 5-5 of Figure ii, the front plate being en
tirely omitted and the spring being also omitted
in the interest of clearness.
Figure 6 is a view corresponding to Figure 4, but
showing the hooks of the front plate in the posi
tion corresponding to the full line position of
Figure 3.
Figure 7 is a view similar to Figures 4 and 6,
but showing the hooks of the front plate in the
?nally locked position corresponding to the
dotted lines position of Figure 3.
Figures 8, 9 and 10 are views respectively cor
responding to Figures 1, 2 and 3, but showing an
inverted construction hereinafter described.
Referring to the drawings, I designates a back
plate which, in practice, may be conveniently
stamped up from sheet metal in such a way as
to dish the back of the plate and impart thereto
sufficient thickness to be ornamental and also to
permit of an interior dimension su?icient to re
ceive the tabs of the front plate, presently de
scribed.
As shown in the drawings, the back plate is
provided with upright slots 2 adjacent its oppo
site ends, while between these slots the plate is
punched to form countersunk holes 3 through
30.
5
which screws 4 may be passed as shown in Fig
ure 5. The screws may be screwed into any ?rm
support, such as a wall 5, shown in the latter
?gure, to ?rmly mount the back plate I thereon. 40.
Extending across the back of the back plate is
a leaf spring 6 held in place by a pair of rear
wardly stamped retainers ‘l and an intermediate
punched boss 8 which holds the spring 6 in a
bowed condition and under tension with its op as
posite ends extending across the lower ends of
the slots 2.
It is to be noted that the back plate is stamped
up to provide the marginal skirt 5 which gives it
the desired depth, while the countersunk holes 7
are so formed that the tapered wall thereof bears
against the surface of the support 5, so that,
when the screws ii are inserted, they may be
screwed in tightly to rigidly secure the back plate
in position without deforming the latter.

The front plate l0 may also be conveniently
stamped up from sheet metal with a marginal
skirt I l to give it the desired appearance of depth
and the lateral edges of said skirt are provided
with rearwardly extending upright tabs l2. These
tabs are provided in their upper end with notches
[3’ of a width substantially equal to the thickness
of the stock from which the back plate is
punched. In the lower edges of the tabs I2 are
10 similar notches [4’, but these latter notches are
somewhat wider and may conveniently be of a
width substantially equal to the combined thick
ness of the stock of the back plate and the diame
ter of the spring 6. The notches I3’ and [4' thus
15 form at the top and bottom of each tab up
wardly and downwardly extending hooks l3 and
M, respectively.
The ?xture to be detachably mounted by the
structure of this invention may vary within wide
20 limits, but, for the purpose of illustration, it is
shown as a soap dish i5, the frame of which is
welded to the front of the front plate ID, as clear
ly shown in Figure l. I wish it understood, how
ever, that I may use the ?ange of this invention
25 for any ?xture and that the showing of the soap
dish is not to be understood as limiting the use
of this invention.
'
The parts are manufactured as shown in Figure
l with the front and back plates separate from
(leverage which sets up a shearing strain on the
hooks [3, rather than a downward pressure.
The spring 6 is more than adequate to withstand
the normal downward pressure, so that the
actual load is carried by the hooks l3 and these 5
are well adapted to withstand the strains of
ordinary use. Nevertheless when the front plate
is to be removed, the pressure is applied directly
to the front plate or in such close proximity there
to that the pressure is entirely or almost entirely 10
downwardly and this permits the removal of the
1 parts.
I have found that the form of the invention
described is the best form for practical purposes.
It is apparent, however, that the structure may
be used in an inverted position by simply welding
the soap dish upsidedown on the front plate ll’).
In this case, the Whole of the resulting structure
would be inverted and the spring would coact
with the notches [4' at the top instead of at the
bottom as shown in Figures 8, 9 and 10. Similar
ly it is within the purview of this invention to
mount the soap dish on the front plate at an
angle of 90° to the position shown, so that, when
the parts are mounted, both plates will be up 25
right instead of horizontal as illustrated, while
the slots 2 will extend in a horizontal direction.
I do not ?nd these latter two structures as desir
able as the preferred form of the invention
30 one another. In securing the mounting on a ?rm
shown, but the present invention is to be under
support the back plate is ?rst secured in place
by passing screws 4 through the countersunk
openings 3 into the support 5. The lower por
stood as not limited to the arrangement illus
trated, as others may prefer the modi?cations de
scribed. The claims are, therefore, to be con
tions of the tabs l2 are passed through the up
35 right slots 2 and the lower hooks I4 are hooked
over the spring 6, as shown in Figure 2. There
after pivotal movement is imparted to the front
plate, as indicated by the arrow in Figure 2, and
at the same time a slight downward pressure is
410 exerted on the ?xture I5, in order to bring the
rounded camming edges I6 of the hooks I 3 into
engagement with the upper ends of the slots 2.
Continued pressure in the direction of the arrow
.will cause the tabs I2 to pass entirely through
45 the slots 2 and through the position shown in
full lines in Figure 3 until the notches l3’ aline
with the wall of the back plate, whereupon the
spring 6 will elevate the tabs I2 and cause the
hooks l3 to snap into engagement with the back
50 plate, as shown in dotted lines in Figure 3 and in
full lines in Figure 7.
The parts will thereupon be in assembled rela
tion and will remain so until it is desired to re
move the ?xture. To accomplish this, down
55 ward pressure is applied to the front plate II] or
to the ?xture adjacent the front plate, and when
this pressure is su?icient to force down the ends
of the spring 6, the upper hooks l3 may be dis
engaged from the wall of the back plate and the
60 front plate may be then removed by reversing the
‘operations described.
It will be noted, however, that, when the front
plate is in mounted position the screws 4 will be
concealed and the front and back plates will ap
65 pear to the casual observer as a unit, without
any visible means of attachment either to one an
other or to the wall. Nevertheless the parts may
be assembled or dismantled in an expeditious and
efficient manner. When the parts are assembled
70 there is practically no tendency to inadvertently
disengage them through the application to the
20v
strued accordingly.

It will be noted that the front plate Ill, as well
as the beveled skirt of the back plate l, are pro
vided with bosses H and 18, respectively, which
register with one another. These bosses not only
serve to strengthen the plates and impart a pleas
ing appearance thereto, but the bosses I'l facili 40.
