SEWING CABINET
l’atrick H. Harmon, San Fernando, Calif.
Application May 23, 1936, Serial No. 81,529
6 Claims. (Cl. 223--l07)
My invention relates to improvements in work
boxes for use more particularly as a sewing cab
inet although it may be used in other capacities
as will presently appear.

of the trays, or, to closed position as determined
`The invention is designed primarily to provide
a cabinet of the folding sectional type which em
bodies a pair of tray sections hinged together
and suspended for swinging movement into either
open position to provide a pair of open top trays,
10 or, into closed position to provide a closed com
partment, the sections counterbalancing each
other in Veither of said positions against move
ment to the opposite position so that no catches
or other locking devices are required to hold the
sections closed or open.
>Anotl‘ier'object is to provide a cabinet of the
class and for the purpose above indicated which
is simple in construction, strong and durable, and
economical to manufacture.
Other objects are also comprehended by my
invention all of which together with the exact
nature of my improvements will be readily un
derstood when the following description and
claims are read with reference to the accompany
ing drawing:

In said drawing:
Figure l is a View in vertical section taken on
the line i-l of Figure 2, looking in the direction
indicated by the arrows, and illustrating the
30 cabinet of my invention with the sections in
closed position.
'
Figure 2 is a View in transverse section, and
Figure 3 is a View partly in transverse section
and partly in side elevation illustrating the sec
tions in opened position;
together as at 9 at their open edges whereby said
trays may be relatively swung to opened position
determined by engagement of said small ends
v
Referring to the drawing in detail, and by ref«
erence numerals, the illustrated embodiment of
my invention comprises a pair of opposed end
uprights I of any suitable edge contour, conw
¿n nected together at their upper ends by a bar i?,
shaped to provide a hand grip 3 for carrying the
cabinet from'place to place, and similarly con~
_nected at their lower ends by a bar 3'.
by engagement of the open edges of said trays. 5
The trays d and 5, in their fully opened position
incline outwardly and downwardly to further fa
cilitate access to the interior thereof in said
opened position.
The trays li and 5 are suspended from the up
connected side by side to the uprights I and to
the sides 'l of said trays. Preferably said links
are pivotally mounted in metal plates il and i2 15
suitably secured to the uprights and trays, re
spectively, as by screws it.
The pivotal con
nections of the links it to the trays l and t are
offset rearwardly of the transverse center of said
trays and also oliset below the longitudinal cen
ter of said trays whereby in the opened positions
of said trays the greater portion of the weight
thereof is outside the points of pivotal connec~
tion of the links lil thereto. This feature pro
vides for each tray in its opened position coun
terbalancing the other against movement to
closed position. The pivotal points of connec
tion of the links It to the uprights i and trays
il and 5 are relatively arranged so that the links
incline downwardly and outwardly from their
points of connection to Said uprights whereby
the points of connection of the links to the trays
are always laterally offset outwardly from the
center of gravity of said links.
As will be clear
this feature provides for the trays being urged 35
towards closing position by their own weight after
they have been swung inwardly on their hinges
9 past a vertical dead center position relative to
the pivotal points lil’ of connection of the links
l0 thereto.
40
Each tray il and 5 is provided with a centrally
located transverse partition ld which in the
opened position of the tray inclines upwardly and
Intermediate the uprights i and swingingly
outwardly to facilitate access to the rear comn
mounted thereon, as presently described, is a pa' 1
partment formed in the tray thereby, and in the
closed position of the tray inclines upwardly and
of tray sections 4 and 5, respectively, each com
prising end walls E, side walls ‘l and a bottom
wall ß. The trays ¿i and 5 are designed so that
they gradually increase inv depth from one end
C11 0 to the other and are thereby formed with large
and small outer and inner ends, respectively.
Preferably the bottom walls 8 of each tray are
relatively divergent outwardly from the end wall
6 to facilitate access to the interior of the trays.
The small ends 6 of the trays 4 and 5 are hinged
55
10
rights l, by means of opposed pair of rod~like
links it, the links of each pair being pivotally
inwardly so that implements or articles located
on said partition will gravitate toward the outn
side of the tray for a purpose which will be clear.
The small ends of the trays It and 5 are provided
with inwardly extending ledges l5 at their open
edges which in the closed position of the trays
form upright partitions for preventing the conm
tents of the trays from intermingling.
It is to be noted that the described means for 55
>aiosfrri
suspending the trays for independent swinging
movement causes them to swing up to an ele
vated position when moving from closed to
opened position. Thus the cabinet may be built
low and the contents of the trays easily reached
when the latter are opened.
This feature together with the described in
clination of the trays and the outer end walls
and partitions thereof provides for easy removal
10 of articles from the bottom thereof and for ren
dering articles on the bottom of the trays readily
visible to a person seated alongside the cabinet.
The foregoing is a detailed description of a
preferred embodiment of my invention and it is
believed that the construction and advantages
thereof will be clear without further explanation.
It is to be understood, however, that the precise
details described are illustrative of a preferred
embodiment of my invention only, and that right
is herein reserved to changes and modifications
of such details falling within the scope of the
claims appended hereto.
What I claim is:
l. A cabinet comprising, a pair of spaced apart
opposed uprights, a pair of open top trays be
tween said uprights having end and side walls,
respectively, and hingedly connected together in
end to end position for folding movement into
closing and opening relation, and means for sus
pending said trays from said uprights for relative
swinging movement, said means being pivotally
connected to said uprights and to the sides of the
trays, respectively.
2. A cabinet comprising, a pair of spaced apart
opposed uprights, a pair of open topI trays be
tween said uprights having end and side walls,
respectively, and hingedly connected together in

40 pending said trays from said uprights for relative
swinging movement, said means being pivotally
connected to said uprights and to the sides of the
trays, respectively, said means being pivotally
connected to the respective trays each at points
f so that the centers of gravity of the two trays
when in closed position will lie between the two
pivot connections so as to hold the trays in closed
position and when in open position the individual
centers oi gravity of the two trays will be out
ward oi the pivotal connections thereby main
taining the trays in their open positions.
.
3. A cabinet comprising, a pair of spaced apart
opposed uprights, a pair of open top trays be
tween said uprights having end and side walls,
will be outward of the pivotal connections thereby
maintaining the trays in their open positions, said
trays having their hinged ends inclined upwardly
and outwardly from the hinges when the trays
are in closed position whereby the trays will slope
downwardly and outwardly from the hinges when
they are in open position.
4. A cabinet comprising, a pair of spaced apart
opposed uprights, a pair of open top trays be
tween said uprigl’its` having end and side Walls, 10

pending said trays from said uprights for relative
swinging movement, said means being pivotally 15
connected to said uprights and to the sides of the
trays, respectively, said means being pivotally
connected to the respective trays each at points
so that the centers of gravity of the two trays
when in closed position will lie between the two 20
pivot connections so as to hold the trays in closed
position and when in open position the individual
centers of gravity of the two trays will be outward
of the pivotal connections thereby maintaining
the trays in their open positions, and said trays 25
being deeper at one end than at the other and
inclining outwardly and downwardly in their
opened position with the hinged ends abutting
and limiting the outward swinging of the trays.
5. A cabinet comprising, a pair of spaced apart 30
opposed uprights, a pair of open top trays be
tween said uprights having end and side walls,
respectively, and hingedly connected together in
end to end position for folding movement into

pending said trays from said uprights for rela
tive swinging movement, said means being piv
otally connected to said uprights and to the sides
of the trays, respectively, said means being piv
otally connected to the respective trays each at 40
points so that the centers of gravity of the two
trays when in closed position will lie between the
two pivot connections so as to hold the trays in
closed position and when in open position the
individual centers of gravity of the two trays will
be outward of the pivotal connections thereby
maintaining the trays in their open positions, said
trays having, respectively, a transverse partition
inclining from the bottom of the tray inwardly
and upwardly in the closed position of said tray,
and upwardly and outwardly in the opened posi
tion of the tray and the end walls of each tray
being outwardly divergent relatively.
