CUSHION.

To all whom it may concern Be it known that L MAX Fr'sonrraxn, of

the city of Toronto, in the ccunty'of York,

use with. automobiles, ambulances and the like, having for its object to provide means whereby the abnormal shockdue to'sudden compression of the cushion will be absorbed, thereby preventing the total collapse of the cushion and the consequent shockto a person who may be seated'the'reon.

Further o j'ects are'to provide for'ftheelimination f noise or contact of the said springs one-with another and {to efiect,' if

desired, the-partial .compressionjof certain 'of said springs inorderto increase their efiicient operation. f

The invention consists essentially of the novel construction and arrangement. of the parts whereby the primary springs.-f0rining the foundation of the cushion are reinforced; either directly or indirectly, by further resilient members which may be off strength than the'prirnary' springs. Pockets are preferably provided for the accommodation of the said springs and their reinforcing means, the. springs if desirable being in a state of partial compression Within the said pockets and a suitable fibrous material ex tending around the said pockets both between the same and betweenthe outer covering of the cushion all ofwhich is more particularly described in the following specification and with reference to the accompanying drawing in which,-

Figure 1 1s a sectional perspective view of part of a cushion made according to this invention, certain parts being broken away to more clearly illustrate the structure. Fig,

. is a sectional detail view illustrating the primary spring within one of the pocketsand a secondary spring concentrically dis posed within-said primary spring and also provided with a pocket. Fig. 3 is a transverse section of Fig. 2. Fig. 4 illustrates a method in which the primary spring may be reinforced and the separate secondaryspring.

dispensed Fig.- 5 illustratesas an ex- .ample anoth-er arrangement of the springs,

and' Fig. 6 is a plan of the same;- Similar characters of reference indicate the several figures .ofthe drawing. 3 6.0 1, 1, are the main or-primary springs forming the foundation ofjthe cushion and arranged perpendicularly therein, the. said springs being attached d rectly to the frame. of the cushion, where such a frame is em- 66 ployed, but it is preferred to dispense with such frame and arrange the springs inv fab ric pockets 2, the said fabric pockets being surrounded by felt oiothersuitable fibrous material 3 in such a manner that the internal "I0 construction of the cushion will: be in the .form of a series of spring containing' rolls A.-A. extending from side to side, th e said "series of rolls preferably beingiui'therr eoveredwith a layer of fibrous material f1: be-

-tween the same and the outer coveringbr envelop 5'.

'Where cushions are'so provided with. main Where in connection with automobiles, it isjlO found that they w ork' very satisfactorily under ordinary conditions,- but upon the re hicle passing overa very uneven surface the violent shock will elfect'th'e total collapse of the cushion, beneath the weight of the person seated thereon, the shock "therefore being directly transniitted to the person with consequent discomfort.

- In the present case the total collapse of the cushion under such circumstances is pre vented by the resilient reinforce-ment'of the said springs 1 for a gm of their length. in such manner that after the. primary springsl have been compressed to a certain extent the reinforcementwi ll come into -0 eration, thereby increasing the*"ro or P v P P tion of forcenecessary for" the further compression of the cushion! The most con venient "form of such resilient reiniorce- 10 shorter than the primary springs, although for example, pads of porous rubber or the like may be used for a similar'purpose if desired. These sprin sji may be concen trieallyarraingedv witnin the springs 2, or 10 -may be integral therewith as indicated in Fig. 4 whereby the primary springs 2 are.

7 are fabric pocketssurrounding the reinforcing springs G and preventing noise, which may he causedby contact het-weenthe primary and secondary springs, while also havin; asoneot their'o jects to retain the said secondarv springs in a state of partial '('ompressiom-itso desired; in order to increase their efiieient:operation.

Theproportionate number of primary and secondary springs may be varied a'ecordmg, to requlrel'nents as Inlay-also the respective positions of the said primaryand seeondary sprin g s Fig. of the drawing indicating,

as an example,'an alternative arrangement.

'ith ae'ushlnn of tlus description the required resiliency may he obtained for comfort under ordinary'*eireunwtanees, while- .providing for increased l'eisista'uee, In the and not in a limiting sensc, except as necessitated by the prior art.

What I claim as my invention is:

1. In combination with a eusliion,-lla\'ing primary springs forming the foundation of said cushion, and secondary springs, substantially shorter than said primary springs, and upon eommonaxes with said primary springs, individual pockets also substantially shorter than said primary springs adapted to retain said secondary springs (10- axially within said primary springs.

In combination with a cushion having primary springs forming the foundation of said cushion, and secondary springs; substantially shorter than said primary springs, pockets in which said secondarysprings'are inelosed and n'iaintained in a state of partial .t'ompression.

Signed at 'loronto, in the county of York in the Province of ()ntario, in the Dominion of Canada, this 14th day of January, 1914.
