2 Claims.
This invention has for its main object to provide a spring assembly for upholstery, which is jacketed in a novel manner with a batt of suitable fibrous materiall to provide certain structural advantages, as hereinafter pointed out, to,
gether with the economic advantages also referred to hereinafter.
In the accompanying drawing illustrating a suitable embodiment of the invention,
Fig. l is a perspective view of a jacketed spring assembly, constructed in accordance with the invention.
Fig. 2 is a vertical longitudinal sectional view of the same taken on the line 2--2 of Fig. 3.
Fig. 3 is a vertical transverse sectional view of the same, taken on the line 3-3 of Fig. 2.
corner portions of the outer casing of the ultimate cushion or mattress into which the jacketv ed spring assembly is incorporated.
Fig. 4 is a fragmentary detail perspective view on an enlarged scale, showing a corner portion of the structure.
Fig. 5 is a fragmentary detail view in elevation, showing a corner portion of the structure.
The spring assembly I of the structure may be of any of the large number of types found on the market. The jacket 2, housing or enveloping the same, may be composed of any suitable flbre. In the instance illustrated the batt is composed of a long fibre. such as sisal, and
is equipped with the usual stitch chains 3, com.
The width of the batt 2 is so much greaterl than the width of the assembly l as to enable the side edge portions of the batt 2 to be secured to each other by machine stitching 5, as shown in Figs. 1 and 3. The latter maybe incorporated into the structure, either before or after the stitch chain or other stitching l has been incorporated.
After the'sald stitching 5 has been incorporated to complete the structure, the loose triangular folded batt portions 8 remainvat the corners of the same and these may be turned to overlap the side walls of the structure as shown in Fig. l, or the front and rear walls thereof, as'shown in Fig. 4, and may, of course. be secured in either of these positions electively. The corner portions t are advantageous in that they form what may-be termed fillers for the corners of the assembly I, as they are of twice the thickness of the batt I and obviate the usual insertion of additional padding material into the In introducing the stitch chains 5, the side edge portions of the assembly l are compressed in order to cause the meeting edge portions of the batt 2 along the sides of the structure to be brought into outwardly projecting overlapped relation to each other upon the sewing machine table, the stitch chains 5 being continuous throughout the length of the said side edge portions as shown clearly in Fig. 4.
The structure is advantageous in the respects above described and by reason of its adaptability to the machine stitching 5, is more economically produced than other jacketed spring assemblies known to me.
I claim as my invention:
1. A lspring assembly equipped with a jacket comprising a unitary rectangular uncovered fibre batt of a length substantially equal to twice the length and depth of said assembly and of a width greater than the width and depth of said assembly and having its side edge portions meeting and joined along the sides of said assembly by stitch-chains extending through meeting edge portions of said batt extending outwardly from the resulting side walls formed by the side edge portions of said batt, the ends of said batt being joined at one end of said assembly, the surplusage of the batt at the corners of the assembly constituting substantially triangular double thick projections folded inwardly to overlap assembly equipped with a jacket composed of a rectangular batt composed of relativelyA long fibres adapted to be retained in their normal association and against tearing by stitch-chains,
said batt being of a sufllciently greater width than said batt to cause side edge portions thereof to form side walls of said assembly and being of' sufficiently greater length than said assembly to completely envelop the top and bottom and ends of the latter, said batt being wrapped around said assembly and having its side edge portions stitchedtogether along the sides of the latter and its end edge portions secured together at one end of said assembly, the portions of said batt disposed at the corners of the assembly constituting flange elements folded to substantially triangular form and disposed to lie in contact with and secured to peripheral wall portions of the said jacket and provide corner padding within the ultimate upholstery unit into which the jacketed spring assembly is incorporated. l
