UPHOLSTERED SPRING CON STRUCTEON
George It. Beatty, .îacksom Mich., assigner to
Reynolds Spring Company, Jackson, Mich., a
corporation of Delaware
Application November 26, 1934, Serial No. 754,754
6 Claims.
This invention relates to upholstered spring
constructions and more particularly to an ar
rangement for readily securing the springs and
the lower edge of the upholstery on the sides of
5 such constructions.
Attempts have been made to secure efficient
and economical arrangements as above described
and an example of such an attempt is illustrated
by Letters Patent No. 1,387,160 granted to Wil
10 liam D. McCullough et al. This invention is an
improvement over the structure disclosed in the
above patent.
The improvements reside not only
in a construction which may be fabricated more
readily and economically due to simplified con
'15 struction permitting the ready access of tools and
consequently saving in time and by the use of
more simplified tools, but also in an arrangement
permitting the upholstery on the sides to be se
cured on a level with the lowermost portions of
20 the construction and in minimizing the overall
height of the constructions.
An object of the present invention is to provide
a base frame comprising an upholstery and
2
spring securing strip in an upholstered spring
construction by which the border springs may be
rea-dily secured in position and by which the
lower edge of the upholstery on the sides may
be readily and eñiciently secured.
3
Another object of the invention is to provide an
upholstered spring construction in which the
lower edge of the upholstery covering the sides
is secured in such a manner as to permit a con
struction of minimum overall height.
A further object of the invention is to provide
35 an arrangement for readily securing upholstery
or other fabric to an object.
These and other objects will be apparent from
the following specification when taken with the
accompanying drawing in which
40
Fig. 1 is a plan view of a corner of the con
struction having a portion broken away to show
details of the assembly of the upholstery and
spring securing strip at the bottom,
Fig. 2 is a section taken on the line II-II of
45 Fig. 1,
Fig. 3 is a perspective view of an upholstery
securing ro-d, and
Fig. 4 is a section of a modified upholstery and
spring Vsecuring strip showing the upholstery
50 secured in position.
Referring to the drawing the spring construc
tion comprises a plurality of vertical coil springs
I maintained in a predetermined spaced relation
having a cushion 2 resting on their tops and
55 being enclosed at the sides with a skirt 3. The
(Cl. 155-180)
tops of the coil springs I at the border are se
cured to a wire border frame ¿l by clips '5 and
inwardly are connected by crossed braces 6. The
bottoms of the border coil springs I are secured
to the upholstery and spring securing strip 'I -55
and inwardly are connected by the spacing strips
8. Relatively deep sheet metal spring supporting
cross bars 9 constitute spreaders and add rigidity
to the structure.
The structure described above with the’excep- lv10
tion of the upholstery and spring securing strip
'i constitutes the prior art, this invention resid
ing in the construction of the upholstery and
spring securing strip -I and its association with
the spring structure as a whole and in this case y1li
particularly the cross bars 9, the spring I and
the skirt 3.
The upholstery and spring securing strip 1 is
roughly of a W-cross section having at the top
and bottom channels Il! and II, respectively, {2‘0
facing laterally in one direction and intermediate
the channels It and II, a channel I2 facing lat
erally in the opposite direction. One wall of the
channel I2 forms a wall of the channel I0 and
the other wall of the channel I2 forms a wall v'25
of the channel I I. The strip ‘I may be formed in
any usual manner as by rolling.
The upper laterally facing channel I 0 is ini
tially formed large enough to freely receive the
lower edges of coil springs I and the turned up 30
ends I3 of the forks I4 extending from the bars 9.
As shown in Fig. 2 the border springs I »rest on
the bars 9 and snugly fit into the turned up ends
I3. The border coil springs I` and the snugly
fitted fork ends I3 are clamped in the channel I0 35
by closing in or crimping as shown at I5.
The laterally facing channel I I is formed with
a restricted throat and which is sufficiently yield
able -to receive a plurality of relatively short skirt
securing rods or the like I‘I after the lower edge 40
of the skirt 3 has been laid in the channel II.
The skirt securing rods I'I have a somewhat larger
diameter than the width of the restricted throat
IB with the skirt 3 covering the same so that
when the rods I'! have been forced past the re- 45
stricted throat I6 into the bottom of the chan
nel I I they are yieldably retained therein. It
has been found that if the rods I'I are ma-de of
suitable wire about one and one-half inches long
and spaced about one half inch apart, a very
satisfactory connection is obtained. In actual
practice the skirt 3 i-s forced into the channel II
by the rods Il so that only one operation is re
quired to make the connection. The lower edge 55

of the channel II is iinished by the return
bend I8.
The channel I2 is made suñiciently deep to
provide walls of adequate depth for the channels
I0 and II and to receive a backing tool during

have provided an upholstery and spring securing of said channels being arranged to have secured
strip which not only eiiectively secures the border therein a coil of a spring and the lower one of
coil springs I and the lower edge of the skirt 3 -said channels being arranged to have secured
but permits the securing of the same in a rapid
and expeditious manner.
It is pointed out that as the invention resides
in the base frame strip and its association with
the remaining structure, I do not Wish to be lim
ited to the details of the remaining structure but
25 only by the scope of the following claims:
1. In an upholstered construction, a base frame
comprising a channel member having two later
ally and inwardly facing open channels one dis
