Frank Schlachta, "Pittsburgh, 1 Pa., assigner of
one-half to. AndrewÍK. Sypien, Pittsburgh, Pa.
„Application November 24, 1934,'Serial No. 754,618
3 Claims. (Cl. 155-184)
'_ This invention relates to upholstered furniture,
such as davenports, sofas .and vchairs ofthe loose
cushion seat type as used in living rooms, 'hotel
lobbies ëtc.
Ll
In ordinary practice, furniture of this kindis
provided with a cushion support, commonly called
in the trade platform, having a plurality of heli
cal springs which rest on its bottoms on a laced
webbing. The tops of said helical springs are
tied together with a strong twine, coveredwith
a single piece of canvas and ñlledwith moss and
cotton and again covered with a single piece of
canvas which is tacked to the rails of the chair
or sofa. Before the top canvas is tacked to the
side rails of the furniture the space between the
two arms, the back and the platform is packed
with moss or other suitable material, so that no
gap exists between the platform and the arms
and back.
'
In the above described construction, a» great
percentage of the ñexibility of ¿the springs near
the arms and the back is lost,`due to this com
pact packing. Another disadvantage of this con~
struction is when, for instance one of the helical
springs or the tie-cord breaks, the platform has
to be entirely ripped open when replacing defec
tive parts.
My invention relates Vparticularly to improve
vments which overcome the disadvantages ‘out
30 lined aboveand the ob-jects of my invention :are
as follows:
LO
The primary object of my invention is to pro
vide'upholstered’furniture such as chairs, divans
etc. with a removable platform-which .ishingedly
'attached to the 'front Vrail of said chairs, >divans
etc.
' Another object of my invention is to >provide
40
to manufacture.
.
10
With the foregoing and other objects in view
this invention consists of the novel construction,
combination and arrangement of parts, as here
inafter set forth and more specifically described
and illustrated in the accompanying drawings 15
wherein is shownsan embodiment ofthe inven
tion, but it is ‘to‘be understood that changes,
variations and modiflcations'can be resorted to
which vcome withinlthe -scope vof the claims here
unto appended.

`
ÁAnother Vobjectof'the invention is to provide
upholstered furniture, such as chairs, divans, etc.
in which the construction of the platform may
be readily inspected before purchasing.
Still another object of the invention is to pro
vide a platform of upholstered chairs, divans,
etc. which permits easy cleaning, thus making
such furniture clean, mothpro'of and therefore

fit of` the Ahelical springs is attained by eliminat
ing the packing between the arms, the back and

and parts broken away; and
'
inventiomwith parts eliminated and parts broken
away.
z `In carrying outmy‘invention, I provide a chair ,45
or divan frame 8, comprising the side rails 9, a
:front :rail -.I.0,.a1rear‘rail VI I 4and the legs I2.
At this time, it is Yimportant to mention that
no change of the present method of construct
ing chair or divan frames is required when using 50
my improvements, furthermore old upholstered
chairs or divans may be readily altered or mod
ified at low cost, without changing the structure
of the conventional frame work of the same.
A series of helical springs I3 are placed in the 55
2
2,107,087
usual manner, resting on a laced webbing I4,
which is tacked to the underside I5 of the rail
ings 9, IU and I I as shown in the various views of
the drawings. The bottom I6 of said coil springs
I3 is securely fastened on said webbing I4.
The upper portions I1 of the outer helical coil
springs I3 are connected at the edges by means
of suitable connectors I8 to a stiff wire frame I9,
which is of rectangular shape, similar to the
10 shape of the seat frame 8 and is preferably
rounded at the corners, to fit partly around the
helical corner springs, as best shown in Figure '7
of the drawings. The said wire frame I9 is fully
covered with canvas 20, whichcovering extends
15 downwardly and is tacked to the upper edge 22
of the rails 9, III and II by means of tacks 2|.
In order to prevent excessive forward swaying
of the platform, the wire frame I9 is yieldingly
held at the rear end by two sets of three coil
20 springs, one at each corner, arranged in a man
ner as shown in Figures 4 to 6.
The aforesaid
arrangement comprises a pin-bolt 23, one end of
which is pointed,.as at 24, and the other end 25
is threaded.
25
_
,
This pin-bolt 23 is first inserted through the
aperture 26 of the back-brace 21 and two coil
springs 28 and 29 of proper proportions are
slipped over the protruding end of said pin-bolt
23. The pin bolt 23 is then driven into the top
30 of the rear rail II and tightened by means of a
nut 30.
`
Should it be desired to make the said springs
28 and 29 adjustable an additional nut 3| may
be placed below the back-brace 21, as shown in
35 Figure 6. Another coil spring 32 is hooked
around the pin-bolt 23 between the coil springs
28 and 29 and fastened to the wire frame I9, in a
manner vas best shown in Figure 6.
A quilted pad 33, of similar outline as the seat
40 of the furniture and of uniform thickness with
the exception of the two sides and the rear edge,
is being employed in my invention and the under
side of the front edge of said pad 33 is attached
with tacks to the top portion of the front rail
45 34, so as to provide a hinged front end which will
permit flapping over of said pad 33 when desired,
as is clearly illustrated in Figure 5 of the
drawings.
.
`
Referring now to Figures l and 5, pad 33 is
50 provided with thinned out edge portions 35 at
three edges, so as to permit these edges toibe
conveniently pushed under the arms and the
lower edge of the rear or back of the furniture
by pressing downwardly upon the pad, thus, a
55 seal between said platform and the arms and the
back of the furniture being effected when pad
33 is in its final position.
'
At each corner of the pad 33 I provide a metal
ring 31 secured thereon (Figure 5) and under
60 neath the back brace 21 in near proximity vof the
pin-bolt 23 I provide a 'small hook 39. When the
pad is placed into final position as shown best in
Figures 2 and 5, an elastic string 40 may be tied
around said ring 31 and hook 39, this is to pro
65 vide additional means to prevent thefpad from
wrinkling.
'
In order to conveniently remove said pad 33
when it is desired to clean or repair the inside
of the platform, I provide a loop 36 which isl
sewed on the back edge of the pad as clearly
shown in Figures 2 and 5. By taking hold of
said loop 36 and by pulling frontwardly or to
wards the operator the pad 33 will be released
from its hold under the arms and the lower endV
of the back of the furniture, thus exposing the
elastic ties 40 due to its elasticity, and it is now
possible to easily remove these ties from the 10
hooks 39.
It is believed that the operation of the device
will be readily understood, without a further de
tail description of such operation, in view of the
purpose and function of the different elements
having been set forth previously. I only wish to
add that the thinned out edge portions of the
pad at the arms and back are pushed between
the underside of the arms and back by depress
ing the helical coil springs with the palm of the 20
hand. When released the said helical springs
force the edges of the pad tightly against the
underside of the arms and the back thus re
taining the pad in a stretched position at all
times.`
