SPRING CUSHIONED UPHOLSTERY Filed Oct. 8, 1939 Patented Sept. 27; 1932 JOHN HILTON, or DUBLIN COUNTY, IRELAND seameousnronnn urnons'rnnr Application filed October s, 1930, Serial No. 487,248, ma Great Britain October 16, 19,29.

This invention relates to improvements in spring cushioned upholstery, the object being to provide new combinations and construc-' tions utilizing my flexible and thin tempered 5 steel laths with springs outstanding on each side of the fiat surface of said laths as disclosed in my British specifications Nos. 282,259 and 284,501 p In the prior art, according to my British specification No. 104,787 the series of laths with outstanding springs on either side of same are clearly arranged to form a single framework with the ends of the lathe connected to each other for this purpose and so form a mattress or a cushion for application to a fiat surface, but is not suitable for application to articles having curved contours, and if applied to curved contours the above framework would be noisy in operation and would be subject to undue strain and cockling or warping out of the desired shape when applied to a variety of contours or a combination of contours such as in cozy corners or to arm chairs or other articles having curved contours owing to the fact'that it forms a complete framework as above and therefore does not permit of separate or independent operation of each lath with its springs.

According to my present invention, to overcome the above disadvantages and to insure that the desired contour will be given on curved surfaces or combinations of curved surfaces without undue strain or cockling or warping of the laths with their springs and to insure silent operation of the same, the spring cushioned upholstering such as chair frame backs and cushion frames, lounges, couches, arm rests of same and box mattress frame tops embodying a base or support shaped to the contour of the finished upholstery are combined with a series of thin and flexible tempered steel laths with springs of equal lengths on one side of same and springs of equal lengths on the other side of same whereby the same arranged separately to form a series with their springs follow the aforesaid desired contours of said furniture 0 and are thereby adapted to opeate silently on any desired contour, each separate tem- Fee:

pered steel lath having its opposite end-suit- V each separate lath with itsoutstanding springs'forms a separate unit which can be independently worked into any desired contour or combinations of contours, without being strained or stressed or made noisy by be ing connected to the adjoining lath with its sprlngs. g I

For box spring mattresses onwhich it is desirable to have a convex surface, it is usual to fasten single springs together by twine in a suitable wooden frame and to tie down the springs with twine to get the desired shape or contour. These connections break very quickly in use and exert an unequal strain on the springs so tied down; and according to my method of construction and arrangement it is only necessary to make a box having its top curved to'the desired contour so that the temperedsteel strips and their accompanying springs follow the desired con tour when laid on said top.

In the accompanying explanatory dia- 'grammatic drawing Fig. 1 shows aside elevation representative of a chair frame back or sofa back of which a fragmentary front elevation is shown in FigQ. Fig. 3 shows a front elevation representative of a cushion frame or lounge or couch, of which a fragmentary plan view 1s shown 111 Fig. 4. Fig. 5 shows an end elevatlon of an arm rest of same of which a. fragmentary plan view is shown in Fig. 6. Fig. 7 shows a plan view of a box spring mattress frame top of which an end elevation is shown in Fig. 8, all of the foregoing figures showing examples of the application of said flexible tempered steel laths to furniture constructed with the desired contours; and the same reference numbers are used for the same parts throughout. With reference to Figs. 1 and 2, a series of single or separate thin and flexible and tempered steel laths 1 have their opposite ends at 2 suitably fastened or nailed to the back 3 so that the outstanding springs 4 and the lath 1 follow the desired contour 5 of the seat back it being then only necessary to cover over the springs 4 in the known manner with suitable covering material indicated by 6.

With reference to Figs. 3 and 4 the seat is also provided with the desired contour at 7 and with side protuberances 8 to which the opposite ends of the lath 1 are nailed at 9 so that the desired contour is similarly given to the spring'cushioned seat which is similarly covered over with suitable covering m material 6.

With reference to Figs. 5 and 6 the arm rest is similarly constructed to the desired contour shown in Fig. 5 and is provided with protuberances 10 to which the lath 1 is nailed at 11 so that the outstanding springs of thelath l and the lath itself follow the desired contour and only require tobe covered over with suitable material 'indicated by 6; and the two-outermost springs indicated by 12 are preferably parallelbarrel springs so as to clear the bases of the adjoining conical springs. A v V WVith reference to Figs. 7 and 8, the top 13 of the box spring mattress is shaped to the contour shown and is provided with side protuberances 141 to which the opposite ends of the laths 1 are nailed at 15 so that the lath 1 and the outstanding springs 4t similarly take the desired contour and are similarly cov- Q;-ered over with material indicated by 6.

The innermost bases of the springs a may be suitably nailed or fastened to the contour 7 of the furniture, and these springs 4 are of equal length on one side of the lath 1 and are 5; valso of equal length on the other side of the lath 1, and their inner ends are suitably attached in any convenient and known manner to the lath 1.

Having described my invention, I claim In combination with spring cushioned upholstery embodying a base support shaped to the contour of the finished upholstery, a series of separate thin and flexible and tempered steel laths with springs of equal ;;l-engths on one side of same and springs of equal lengths on the other side of same said laths being arranged separately with their outstanding springs and adapted to form a series with their springs following the aforelpaid contours of said furniture and being thereby adapted to form any desired contour, opposite anchoring parts arranged and secured on said furniture at opposite ends of the desired contours, the opposite ends of said flitths being anchored to said opposite anchoring parts. a
