SPRING CUSHION ooNsTmrcTIoN.
Application vtiled Iune 16, 1924. Seria-l No. 720,161.
To all 'whom it may concern.'
Be it known that I, SAMUEL Sunxorr', a
.citizen of the United States of America',
and a resident of Chicago, Cook County,- Illinois,have invented' a' certain new and useful Improvement .in Spring Cushion Constructions, of which the following is a specification.
Y This invention'relates to .improvements in spring cushion construction and method of 'I manufacturing the same and' more especially to self-contained spring assemblies for upholstered seat cushions, furniture, mo-
tor cars and the like. f The object of the invention is to provide an improved method of fastening and sewing together the pieces of fabric that'make' up the'outer coverin and inner compartmens or cells into. which the springs are in. sei-ted, the purpose being toprovide ample strength, shaperetaining qualities, easel and rapidity in the sewing operations, and ready insertion of the springs into the cover.
with a portion o A preferred embodiment of the invention is illustrated in the accompanying drawings, in which:
Figure 1 isa to plan view of a cushion i) the fabric removedf-t show the internal structure,
Figure 2 1s an enlarged view 1n. vertical section taken longitudinally or v`lengthwise .spring retaining member before sewed to the cover pieces.
A cushion of the type embodying the features of the invention consists of. a casing of burlap fabric made up of pieces cut to size and' sewn together on machines; Within this casing is a multitude of coil springs arranged in rows, each spring being separated from its neighbor by surrounding walls of fabric, so arranged as to form individual 'cells for each spring. The ciishion may be of any shape, size and thickness, the one herein disclosed being square. l
Considering the cushion as a completed article of manufacture, the same comprises a top cover piece 1 and a bottom cover piece "tances from side to side,
2, the two being designated for the purpose "of this description only. These cover pieces are of equal size and square in shape, bein cut to larger dimensions than the finishV cushion since the margins of each are folded at right angles and their edges brought together and stitched around the sides and ends at 3, thereby forming the boxing or side walls 4 and end walls 5.
. '1 he interior-of the cushion is divided into spring compartments .for the individual springs 6. The Space is divided into longi-A tudinal compartments extending the length of the cushion by' means of a plurality of I'partition walls -7, made of strips of burlap,
stitched along their ed esito the top and bottom pieces and exten ing 'vertically or at right angles therebetween. These partition walls 7. are spaced a art at equal disdividing the space intov six (Figure 1) of these full length com artments.
Dividing each ot'` the lengthwise compartments into an equal number of small Square compartments is a series of division walls 8, spaced apart at equal intervals and extending'transversely between the partition walls 7. The width of the division p walls 8 is less than the distance between the partition-walls 7 so that a space separates the edges of the former from the latter, as clearly shown in Figure 3.
These division walls are not separate pieces but form a series of tabs which are sewn to and form a part of a unitary. member, consisting of a plurality of such tabs i sewn to a long narrow strip 9, the, complete member being shown in Figure 5. This member, when in place, extends lengthwise between the partition walls 7, the lower ends of the division walls or tabs bein stitched to the bottom piece 2, as shown in iiigures 1 and 3, and the narrow conecting strip stitched to the to piece alon one edge only the lines of stitcliing being igndicated by `16 in Figpre 1, and as it will be observed, ex-
tend parallelto and adjacent the lines of stitching 11, of the partition walls 7.' Thus it is seen that the division walls or tabs 8 are not-sewed directly at both ends to the top and bottom pieces, but only at one end, the Opposite ends being sewn to the connecting strip 9, which in turn is stitched to the' top piece 1. In this ymanner one edge of the connecting strip is 'free and partakes of the nature of a flap, the purpose of which will strip 9 is furthermore extended at its ends beyond the length of the` cushion, in the form of end sections` 9", 9, which are carried down halfway of the end wall boxing and their extreme edges includedin the hem made by sewing the edges' of the to and bottom pieces together at 3. This is c early shown in Figure 2. n l
10 Within these square compartments is inserted a spring 6, the. same being separated by the vertical-'wallson four sides. The method of assembling the material to make the cushion involves aiseries of sewing operations which must be carried out in a prescribed' order since otherwise-it would be impossible 'to usel 'sewing machines.
Hence, it is necessary to sew the free ends of the tabs 8 to the bottom piece as the first operation. Thus, beginning at one end of a bottom piece, 'all of the first or, end most row of tabs 8 ofthe several connected tab members, aresewn down by a single operation, then t-he second row, and so on until ,25 all are secured -to the same cover piece.: Next, the partition walls are stitched down.
to the same piece and between the rowsof tabs 8, thereby completing one half of the' by sewing around the Ioutside along the line A 3, one end being left open` for the insertion of'the springs, this operation being termed loading.
. The loading of the cushion is carried out by means of a loading fixture, lwhich in its 40 simplest formare two thin wood or metal strips between which are compressed a row of springs of the number and spacing required to fill'a single row of cells within each' longitudinal compartment. When compressed, the'strips are clamped together and inserted endwise into the open end of the compartment. In doing this, the fixture is inserted between the top piece l and the connecting strip or flap 9, so that it does not encounter the 'division walls or tabs 8. lVhen the fixture is inserted its full length, the same is twisted axially toward and over the free edge of the flap, a halfeturn which brings each spring into its respective com-y partment with the vflap beneath one end. By releasing the fixture, the springs expand and spring into their final positions, whereupon the fixture is withdrawn and the next row loaded. When the loading is completed the open end is sewed up' andthe cushionjis complete.
The advantage of this particular construction, the rapidity and ease of loading is greatly increased, in that the cushion can be completely sewed up for loading, and
connecting tabs Stitc then by the use of afixture the gang method of'loading can be employed, which would be impossible were the edges of the .division tabs sewed. directly .to the top and bottom pieces, thus necessitating the use of the space' at the corners of each cell for-introducing a. spring therein, this being a slow tedious and expensive operation.
Having set forth the important features of the cushion construction embodying the invention, and explained the method of assembling and loading the cushion, I claim:
l. A method of constructing spring cushions consisting of providing a plurality of strips, each'having a series of ed transversely thereof, stitching the free ends of said' tabs to a cover piece in parallel rows, stitching one edge of each strip to another cover piece and sewingpartition strips vto said cover pieces and between the rows of tabs and connecting strips.v
3. A method of constructing springcush ions consisting of providing separate cover pieces, providing aplurality of relatively narrow connecting strips having a series of tabs sewed transversely thereof and 'y at equal distances apart, sewing the free end of one of the endmost tabs of eachstrip in spaced relation along aline parallel to the end edge of one of said cover pieces, sewing the next series of tabs and so on until all are secured to the samecover piec, stitching a series of partition strips to said cover piece, andalong parallel lines between said series -of tabs, applying another cover piece, and
securing one'edge of said connecting strip and the free edges of said partltion strips to.
said last' mentioned cover piece.
' 4. A method of constructing spring cushions consisting of providing separate cover pieces, providing a plurality o f relatively narrow connectingstrips having a series of tabs sewed transversely thereof and at equal distances apart, sewing the free e'nd of one of the endmost tabs of each strip in spaced relation. along a line parallel to the end edge of one of said cover pieces, sewing thenext series of tabs and so on until all are secured to the same cover piece, stitching a series of partition strips to said cover piece, and` along parallel lines between said series of tabs, applying another cover piece, sewing one longitudinal edge of said connecting strip and the free edges of said partition strips to said last mentioned cover piece, sewing the margins of said cover pieces together around the sides and one end of thecushion to form the boxing, one end of said connecting strip being sewed with the end margins-of the cover pieces, and loading the compartments formed by the partition strips,. rom the open end of the cushion by inserting a loaded fixture be- 10 tween the connecting strip and the adjacent cover piece, rotating the xture to bring the springs into the individual spring compartments, and releasing the springs from the fixture.
