mechanisms, one for the production of the Secured upon the top 2 isa base or support arms of a chair, and the other for the produc- 3 having a longitudinally extending trough tion of the arms and likewise the over-stuffed or concave mold 4 secured thereto. Said back. trough is preferably formed from sheet metal In said drawings, and is secured fixedly in place except at its Figure 1 is a perspective view of the press inner edge where, as indicated at 5, it is free and extends'upwardly abovethe base and in overlapping relation to the lower edge of the side compression member 6. As will be seen the mold is open at each end and the two molds 4 and e r-are set in slightly converging relation toconform to the angularity desired to be givento the finished chair arms from the back to the front. e

Hingedly connected to the inner port-ion of base 3 and extending lengthwise thereof is the presser plate or member 6an'd having that face whichis next to the mold or trou h l I i u u c V ,I 1 l g ven that contour which it 1s desiredto 1mpart to theinner side of the chair arm. In

the instant case the presser plate is provided with a wedge-shaped block or'filler piece 7 which when the parts are brought into pressmg relation Wlll effect the desired contour of the finish fabric by compression of the underlying filling. I

- The base 3 willbe provided with a series of pins 8 along its upper face outward of the trough l and likewise with pins 9 at each end below the trough. Pins 10 will also be provided in the. ends of the presser plates 6.

Presser plate 6, where both arms are to I be formed at the same time, is interconnected with the'presser plate 6 -through-a pair of in .terconnected arms or levers 11 and 12, said levers being hingedat their outer ends to the respective plates 6 and 6 and to each other at" their inner ends. With the parts in the position shown in Figure 1, in which the presser plates 6 and 6*.are retracted, the levers 1 11 and 12, which in effect form a toggle, abut 6 while the stretcher cloth 15, which is attached to the inner end of the cover 1l,talres the position shown in Figure 2-- In empaling the cloth or covering 14 the operator will take care that it does not contact the trough but stands away therefrom as indicatedin Figure 3. He will then place the filling over the cloth as indicatedat the right in Figure 2'. This filling may be of any approved form but preferably there isfirst imposed upon the cloth a layer of, cotton batting 16 and immediately over the trough and upwardly adjacent the presser' plate 6 a second cheaper filling denoted by 17. -.This is, of course, done upon both sides-where two arms are to be sii'nultaneously forme'd'upon the chair frame. The chair frame is shown in Figures 3 and 4 and is of the usual form and embodies, among others, the upper arm elements18, and the intermediate and side braces 19 and 20,'respectively. Attached to the upper elements 18 and 18 are springs 21 but said springs need not be present and in fact will not be present where certain furniture elements are being produced under the present method,

lVhen a chair frame is placed upon the apparatus the parts come to the position shown -Figure 3, the fabric 1% being slightly stretched by the weight of theimposed chair frame. I p r A plunger or platen 22 is then moveddownwardly against the chair frame and pressure'isapplied through any suitable means (not shown). Prior to this, however, the operator will preferably slightly inturn the edges of the cotton batting 16, see Figure 8,

so that when the platen 22 isfully lowered the edges of the batting will roll inwardly as the frame moves downwardly. At the same time the finish covering 14 w ll be stretched and drawntaut over the filling and the presser begin to move to pressing position as the chair frame is moved downwardly but they stand away suiliciently from-the chairframe during such period as to prevent a dragging effect being exerted upon thefilling.

With the pressure still exerted and the covering clamped in the troughs or forms the operator draws the stretcher cloth out-- wardly over the intermediate brace 19 and tacks it to the outer face of brace ZOand 9O as the case may be. He then drawst-he edges of the :linish cloth 1% from the pins and tacks the same to the various frame elements, 1' these steps may be reversed. aft-er which front finish panels as 23 shown in part at the left of Figure 4, may be positioned to cover the edges at this poi t. ()utside finish fabric (not shown) will also be positioned and tacked in place but as these finish steps are wellknown and have no direct bearing upon this invention full exposition thereof is not deemed essential.

The platen 22 is then raised, the links 11 and 12 broken from their straightened position to retract thepresser plates 6 and Y6 after which the chair islifted off of the machine.

Not only does the machine form and contour the arms but it has been found in actual practice that by havingthe chair ailin-v K the plate 1s provided wlth a trough-shaped verted position no difiicnlty is experienced in maintaining the filling or stunmg in place and it likewiseenables the operator to more ez-rpeditiouslyhandle the stretcher strips and tacl-iat 1e same in place.

linl igures 5 7 inclusive thesaine general In this showing tie trough elements are shown as having a slightly tili'ibl'fiilt contour and the filler strips Tare omi ted; the parts are tl'ierefore numbered as in the above (5 scription. v 2

As will be seen upon reference to Figures 7 and 8 the frame of the machine isprovided with a cross bar E l formed with groove in its upper face. to receive the rounded lower end of a baclr contouring and compression member designated generally 25 This arrangement allows thecompresslon member to he rocked and for the purpose of effecting such movement a toggle compria ing links 26 and 27 is interposed between a fixed portion of the machine and a bracket attached to said member 25. A hand lever 29 connected to the toggle by a rod 30 is pro vided-for actuating the toggle and con sequence rocking the compressor plate.

On its outer face ad acent its lower end member or element 31 curved or contoured to conform with the top of the back of the chair which is to be upholstered. A series of pins 32 extend outwardlyfrom the plate below thetrough to which the cover goods for the forward face of the back is attachechthe goods being carried over the trough, upwardly along the plate and over the upper end thereof. Such goods may have stretcher strips attachedto its sides as is usual.

As will be best seen upon reference to Figure 5 the upper part of the plate 25 is materially narrower than the lower portion which carries the back top conforming trough 31 or is of a width somewhat less than the distance between the arm compression plates 6 and 6.

Extending outwardly from each of the side edges of plate 25, at the upper narrow portion thereof and at right angles to the face of theplatefls a blade or wing denoted respectively by 33 and 33 Said blades are preferably formed from rigid sheet metal plate and the lower edges thereof are rounded as shown in Figures 7 and 8.

Assuming that the form of press just set forth is to be employed the operator will position the covering elements and place the stuffing thereon, the stalling for the back extending up from trough 31 and resting on the fabric overlying the back compression plate. With the partslin the position shown in F igure a chair frame. having the back springs secured to the backframe will be placed'in an inverted position, as before, on

the press andforced downwardly. The arms will of course be contoured as above set forth and in addition theupper curved and rounded edge of the back will be likewise contoured by the trough 31. Lever 29 is then depressed straightening the toggle and thereby'rocking the back compression plate forcing the covering goods and filling firmly and smoothly against the back sprii'lgs. At the same time wings 33and 33 will carry the stretcher strips attached to the back covering l etween the usual upholstering strips of the chair frame and to the rear of the frame where they may be readily tacked. So too, they will: carry the stretcher strips at the ends a of the arm coverings or the ends of said coverings through in. a like manner. This obviates the necessity of theuse ofthe usual stufling stick commonly employed, along with its attendant disadvantages. Again, the

wings separate the filling between the arms and the back when the operator is positioningthe same. y

The back contouring element in the structure, as above described, is designed primarily for forming backs, the upper portion of which are intended to be completed by an imposed wooden finishing element. It may be used, however, for forming strictly overstuffed backs as well.

As will be appreciated by those skilled in the art the machine in both of its described forms makes for better and more expeditious work than can possibly be done under old hand methods now commonly in use.

arms and backs and the broader claims are to be so construed.

What is claimed is:

1. That method of contouring and covering over-stuffed furniture elements which consists in securing the covering adjacent its edges over a form and in spaced relation thereto; placing stuffing on said covering; forcing the furniture element against the stuh'ing and thereby compressing the stufling at theinitial zone of contact and thereby tensionin the covering and carrying itinto contact with the form; causing the tension of the cover to produce a compressive action between the stulfing and another face of the furniture element other than that which first contacts the stuffing; securing the covering toth'e furniture element while the covering is held; and finally removing the covered furniture element from the form.
