9 Claims. (Cl. 248-289)
This invention relates generally to the class of
supports and pertains particularly to improve
ments in wall attached brackets for the support
of household utility devices such as rotary can
openers, fruit juice extractors and the like.
The present invention constitutes a continua

' Secured upon the lower end of the pìntle 20
below the tongue I6 is a locking plate 2I which,
as `shown in Figure i3, is of a width sub
55 stantially `equal to the width of the hinge
plate I3 and the forward edge of this locking
plate is substantially semi-circular as shown and
is bordered by the upstanding rim 22 which has
a notch 23 in its edge midway between its ends
and is inclined slightly downwardly from each
side of this notch to the adjacent end.
Secured upon and enclosing a portion of the
upper end of the pintle 2li above the tongue I4,
is the downwardly opening hollow cap v2li `and en
circling the upper end of the pintle and inter l
posed between the top of this cap and the top
of the fixed tubular hinge post I9, is the ex
pansion spring 25. This spring constantly ex
erts an upward pressure upon the pintle so yas ’to
move the lock plate upwardly and _maintain the
top edge of the rim ‘22 in contact with the -lower
between each arm 32 and the lower part of the
mounting plate.
It will be noted that the arms S2 are of slightly
greater length than the feet i8’ of the hinge plate
and that when the hinge plate is mounted upon
the mounting bracket 26 each foot I8’ rests upon
the top of an arm 32 and is engaged at its for
ward edge behind the up turned lip 33.
In order to .conveniently mount the hinge plate
in position `upon the supporting bracket £5 the
top edge of the hinge plate i3' is engaged at each
v,side of the tongue I4 against the under sides of
'the upper arms 3G and behind the down turned
.lip SI, the body portion of the plate I3 extending
outwardly and downwardly from the plate Z'I.

pintle downwardly against the tension of the
spring 25 thus lowering the locking plate 2l to
dis-engage the arm from the notch 23 so that
the arm may be swung as desired. It will be
readily seen that when itis desired to swing
the arm back into operating position it will not
be necessary to -push‘ the pintle 2@ down since

is cut the integral forwardly projecting resilient l
tongue 2S which must be l’iexed or bent rear
wardly when the hinge plate I3 is mounted upon
the supporting bracket in the manner shown in
Figure 2.
At the top edge of the supporting bracket 26
the plate has extending forwardly therefrom, ad
jacent each vertical edge, an arm 3e which ter
minates in the short down turned lip- 3l. The
space between these arms 3@ is suilicient to receive

bracket 2E and the hinge plate are so designed
that when they are in interlocked relation the
hinge plate cannot slip from position under the
strains imposed thereon during the use of the
utility device which is carried upon the arm Ill.
However the hinge plate can be attached to the
supporting bracket and removed therefrom easily
and quickly and without exertion.
