1 Claim.

The invention relates to a cushioned seat, as described in the present specification and illustrated in the accompanying drawing that iorms part of the same.

The invention consists essentially in the novel construction of the frame and the inner covering thereof and the formation of seat back and frame to receive a novel form of outer covering as pointed out in the claims for novelty following a description in detail of the preferred forms of the invention. v

The objects of the invention are to reduce the cost of production in upholstered chairs and chesterfields by eliminating the conventional v stuing and substituting blankets of an elastic material, such as sponge rubber or any soft resilient goods that may be introduced as an inside covering for the frame and thereby producing a very comfortable easy chair or sofa that may in the matter of upholstering be constructed without the necessity of employing expert workmen in that line, and of course lengthening the life of the particular piece as compared with the stuffed furniture that has been in vogue for centuries past, besides insuring sanitary cushioning that may be sterilized simply by the removal of the outer coverings; to facilitate mass production of upholstered goods in the manufacture of furniture, both in the way of the 30 stufling by the piece, making the furniture susceptible to slip covers, and in the way of suspended seat bottoms for carrying the cushion and for affording the yielding veffects tothe weight of the person using the seat; to remove entirely from upholstered pieces the bad results resulting from the continued use of stuffed arms and spring seat bottoms where the weakening of one spring is apt to disarrange the complete seat and where the-stuffed arms are liablel to 40 receive permanent dis'lguring impressions, and in this connection minimize the wear and tear on said bottoms and arms by the use of theA aforesaid piece goods of a resilient nature, in fact throughout the chair or sofa utilize the 45 rubber or elastic piece goods in every direction where the strips, lengths or pads of material will save the destruction or distortion of springs or other parts and thus materially assist in doing away with much stuff usually contributing 5o to the completion of a chair or like article of furniture; to t the inside covers of a frame and other parts so as to be particularly suitable for the more ornamental silk tapestry or other coverings that may be removable for cleaning or. 55 for replacing andyet to make it possible to build `a chair or sofa with simply the inner coverings, and generally to provide in the furniture line of invention simplicity, elasticity and comfort in the covered frame apart from and including outer coverings.

In the drawing, Figure 1 is a plan view of a chair showing the seat bottom with the blanket or pad coverings for the springs partially broken away and omitting one arm and a portion of the back.

Figure 2 is a vertical sectional View of the chair showing the interior of the back and the covered spring bottom.

Figure 3 is a fragmentary sectional detail showing the construction of the covered frame enclosed in the outer cover.

Figure 4 is a fragmentary detail showing one means of holding the resilient pad on the seat bottom frame.

Figure 5 is a fragmentary detail showing another means of holding the resilient pad on the seat frame.

Figure 6 is a sectional detail showing a modification of either form illustrated in Figures 4 and 5 and pieces of the back intermediately broken away showing the back cover.

Figure'? is a detail of the lacing of the outside covering at the' front portion of the seat bottom.

Like 'numerals of reference indicate corresponding parts in the various figures.

Referring to the drawing, the principal description of the details of this invention will be coniined to its application to the construction of an arm chair, or chestereld, and in this arm chair, the frame will be preferably of wood, thoughv it may be of any material desired, and in regard to its general form, is of conventional pattern, the pieces indicated by the numerals I5, I6 and Il representing an arm structure from the top downwardly, while the bars I8 in rectangular form constitute the seat frame as part of the whole frame, this seat frame being supported on the legs I9.

There is nothing novel about the seat frame, it is the same as has been made in the past with the exception of its use in supporting the seat bottom in a particular manner hereinafter more particularly described.

The side boards I'I of the arm structure are secured at the front and rear ends to the seat frame I8, leaving an elongated slot 2I on either side.

The back 22 is rigidly secured to the seat frame I8 and is suitably cushioned as is more particularly described in an accompanying application divided from this application.

The seat bottom 29 is in the form of what are familiarly known as bed springs and the cables 3o of rubber cords or wire cable are strung through the helical springs 3I at the ends and are made into a mesh through the rings or fastenings 32 joining the extended cords alternately and pulling them together, the outer cords on either side being fastened to the frame bars Cured thereto.

of the seat frame i8 by the tie members 33, the rings 32 and the tie members 33 being of rubber cords or wire as found desirable, thus the mesh forming the seat bottom is held by its end loops 34 and 35 to the helicals, though this may be departed from, and these loops may be strung through resilient members, or even laced around bars, the fact that the seat bottom is made in the nature of a bed spring being novel through its particular mode of application.

This seat bottom is associated in its applicai tion with a blanket or pad 36 of sponge rubber of a suitable thickness tol provide resiliency in addition to the resiliency of the spring seat bottom, and this blanket or pad 3S covers the helicals 3l as well as insuring a smooth pad for the mesh of the spring.

Thisblanket or pad is preferably held by a piece of cotton or canvas cemented thereto and secured to the rear cross bar of the seat frame I B and this fastening may be extended along the sides if desirable.

At the front an air cushion is built up by an extending piece of sponge rubber 3B cemented to and reduced at its inner end to bring it flush with the pad 35 and at its outer end cemented to the face piece.) 39 of spongerubber and extending upwardly the'refromto complete the air cushion indicated by the nulmeral 40, which is very effective in resilientlysupporting the seat cushion over the front bar of the seat frame and thus insuring comfort as well as maintaining it in its original orderly position.

'I his form of air cushion is particularly i l lus trated in Figure l, while in Figure the sponge rubber pad extends completely around the corner of the frame and in addition to padding the helical springs pads the corner, and this extension 4I is secured to the front bar.

The sponge rubber covering of the front bar of the seat I8 also extends upwardly over the extension 4l of the pad and is joined to said pad by theI sponge rubber piece 42, which forms the air cushion 43.

The helical springs are shown in Figure 4 'as hooked to the angle bar 44, while in Figure `5 they are shown as hooked to the plate 45 vscrewed to the cross bar.

The covering of the chair is shown as of sponge rubber in blanket ferm, the arm structures having Ythe sponge vrubber blankets 46 se- Usually these blankets are secured to the vframe by an adhesive or by nails, but they may be so fastened by cotton Vstrips therefrom or otherwise as to be more or Aless readily removable.

The chair is Yready for the cushion'which rests on the blanket 36 of the seat bottom 29, this blanket 36 being pierced at intervals, forming the air holes 54, the case of the cushion lalso having air holes and suitable stufling, in fact uthe cushion will usually be of sponge rubber containing springs and its structural details are not included in this particular invention.r

The chair can be considered as finished 'after the seat frame has been completely covered and a case provided for the back, and under such circumstances the sponge rubber will be made in suitable patterns and colors so that 'it lwill prove attractive in moderate priced furniture, but it is preferable to useslip covers.

The chair with the outer covering on is complete and it will readily be seenthat as apiece of furniture, it is both useful and ornamental,- useful from the fact that there is no stuffing in so far as the ordinary use of the term is concerned, for stuinng generally means some kind of Wadding, hair or other kind of threadlike or fluffy material. Such material is eliminated from the upholstery work and the elimination of this material means of course sanitation as Well as facilitating repairs.

There can be no lasting impression left in the sponge rubber such as is common in conventional stuffing and the economy in production and in maintenance is considerable, because of the greatly reduced number of springs.

The same principles of construction throughout may be applied to chesterelds with the sponge rubber as the elastic inner padding fitted permanently or removably on the frame and having a similar seat bottom, though always changes may be made to meet different trade conditions.

The fabric fastening mentioned hereinbefore gin connection with the seat bottom sponge rubber Yblanket may be used much more extensively in the padding of sponge rubber attached to the various parts of the frame, but for purposes of its use, the illustrations particularly in Figures 4 and 5 will show perhaps the best methods of applying it.

'I 'he numeral I 01 shows a strip cemented on to the sponge rubber and drawing the end of the sponge rubber in closely to the frame and securing this strip by the tacks IUS, thus it is not necessary lto put any nails through the Asponge rubber, but simply attach it Wherever it is necessary by means of these strips.

In 'more extensive production, it will be found better to introduce these textile strips or other fabricated material, that is v'of a vfibrous nature, directly into the blankets of sponge rubber during *its 4process of manufacture, as more particula'rly shown in Figure 5, where the fabric |09 projects yf rcnn the blanket intermediate of its depth, Vthat is to say, it is completely submerged in theblanket. 1t is not necessary to have the strip right through the blanket, but just in from the edge all around.

This particular fastening strip is indicated by the numeral 1'09 and as `has already been explained, it can be used very Vextensively in `all the elastic tblankets throughout the chair, -for while the rubber may be fastened "otherwise, in order to `'insii're the greatest sanitation through the remoya-l of this elastic padding, Vthese str-ips may be usedand Vthe inner cover-ing of the chair removed for cleaning purposes.

What we claim iszlAcushion seat comprising a'frame having side, and front land backm'embersfa seat springstructreo'n the top edge of 'said frame and suspended between the members thereof, a blanket of resilient andlspongy material laid Yon `said spring structure and secured tothe outer sides of said frame members land an angle strip of similar spongy material permanently secured to the blanket, Oneedge onthe top and the other along the front ofthe seat and l"having its apex proj ected clear of said blanket to lform'anfair pocket along the'front edge ofthe seat.
