y zo' claims. (o1. 33 176) which the cushion is to fit.

In upholstery work Whether this is made in a factory on a mass production basis or by the individual upholster'er such as is engaged in the repair trade, it is preferable to employ some type of a form or template from which the goods may be cut. Presuming -a chair is to have a cushion,

my cushion form may be adjusted to the'shape.

of the chair seat and given the proper curvatures at the sides, back and front, so that this form may be used to cut the material of the cushion. Again in making cushions for davenportsr and similar long pieces -of furniture in which several cushions are used, the cushion form or' template may be adjusted for the two end cushions and then have the intermediate cushions, the sides being adjustable to the shape desired.

An object and feature of my invention is in the template or cushion form employing a relatively rigid centering orlbody block. This forms the support for adjustable sides, front and back, which may 'be thrust outwardly diiTer-ent distances from the body block and clamped in the correct position. A further characteristic is that the main, side, back and front panels are to a certain extent flexible in order to provide for a curvature at the edge of the cushion. These may be arranged to form convex curves outwardly or concave Yor a reverse convex and concave curvature. My invention also contemplates corner extensio-n strips operating `in conjunction with the panelsv so that these extension strips may be thrust outwardly from their individual panels to lmeet at a corner, depending upon the variation and size and shape Vof the cushion to be made. Further details of my invention relate to the mannerI of lsldably mounting the extension panels and in forming the end or connecting strips at the corners. A lfurther feature lof my inve-ntion relates to forming the panels with achannel-like guide and in having the extension strips slidably mounted in such guide of the panels.

Considered ininore detail a characteristic and feature of my invention consists of a flat preferably rectangular body block provided with a series of front to rear guide tubes or grooves and transverse guide tubes or grooves. Slidably mounted on ythe tubes or the grooves there are adjusting rods, these rods 'extend outwardly beyond the peripheral edge of the'body and havethe contour panels attached'thereto in a loose mannenfthis being preferably by an upturned Afinger-like structure on the outer end' ofeach rod so that when the rods are thrust inwardly the contour panels are positioned in. close contiguityvto the sides of the body block. Clamping bolts with clamps extendvertically through the -body block and are providedwith a detent or keeper end to engage each of the extension rods and clamp or lock the-se in their adjusted position With the contour panels liexedto the proper vshape ace cording to the particular cushion to be made'. In

order to-'permit this flexing of the contour panels f there is preferably a loose connection between the lingers of the rods andthe backA of the panels. A further characteristicy of my invention is that 'the guide structure ofthe panels is made with outward folds having a reversebend at the upper and lower edges of the panels. These folded edges are notched to facilitate flexing. The extension strips are then slidably'mounted in the channel structures. A' 'further' detail featureV includes locking corner pieces which have an interlocking connection with tWo adjacent extension strips and thus retain these 'strips at the corners of the cushion. l y j In view of the'fact that the cushion form having the characteristics of adjustability to develop the outline for cushions of chairs, davenports and the like, it is equally obvious that the adjustable form'when set for a' particular cushion may be used as a guide structure in upholstering a chair suchras the inside back and inside arms of the chair.A It may also be used on the inside arms and inside back of a davenport or similar long piece of furniture. An advantage of using my form'for this purpose is that it is considerably greaterrin thickness, that is, vertical heighth than a cut template and hence more nearly rep-v resents the thickness ,of the upholstery within which the cushion is to t. y

My invention is villustrated in connection with the accompanying drawings', in which:

Referring first to the main details of Figs. l through 5, I employ a body block II. This is illustrated as made in the main of a wood board vor the equivalent, rectangular as to plan having a front edge I2, a rear edge I3 and two side edges I4 and I5. On the bottom of the board there are a series of transverse deep grooves I6 extending from side to sid-e, that is, between the sides I4 and I5 and a series of front to rear shallow grooves` I'I and I8. These grooves are slightly offset one'from the other' depending of course on the size of the block, that is, the distance between the front and rear edges I2 and I3 and likewise if necessary the grooves I6 may be offset laterally where it is necessary to have long extension rods hereunder described. Fitted in each of the grooves there is a guide tube I9, note particularly Fig. 5, held in place by staples or the like at the top of the respective groove and each tube to form a guide for an extensionrodhas one or more cut-outs or openings 20 for the locking purpose hereunder detailed.

Slidably mounted in each of the tubes are a series -of extension rods, such rods being designated by the assembly numeral 25 and the rods extending laterally are designated by the numerals ZBand 21, referring to those which extend beyond the sides I4 and I5. The rods extending beyond the front edge I2 are designated 28 and those extending beyond the rear edge I3 by the numeral 29. Each of these rods preferably has a serrated lower edge 3B, note Fig. 5, for the purpose of obtaining an accurate locking.

The locking arrangement designated as the locking assembly 35 includes vertical perforations 35 in the body block. Each perforation has a large recess 3l extending upwardly from the bottom of the block, note Fig. 6. For each rod there is at least one bolt 38 extending downwardly through the perforation 36. The bolt has a lateral detent or keeper end 39, this being shown as formed with longitudinal teeth or serrations 49 to engage the serrations 30 on the rods. The upper part of the bolt is provided with screw threads 4I on which is threaded a lower nut 42, this being preferably arched or domed on its lower surface indicated 43. Also there is a lock nut 44.

With this 4construction I employ a spring latching clip designated 50 in the details shown in Fig. 5. Such clip has a strap 5I with an upturned nger grip end 52, a portion in the strap is formed with an S or reverse curve 53, this having a slot 54. The upper end of the S curved portion hasa horizontal end strip 55 engaging the dome surface 43 of the nut 42. The bolt thus extends downwardly `through the slot 54 in the S shaped section of the strap-like clip. When this clip is in the position shown in Fig. 5, the bolt is pressed upwardly due to the spring pressure of the S shaped portion of the clip and thus the keeper 39 is brought into locking engagement with the serrations 30 of an extension rod. When it is desired to loosen the locking grip the clip may be tilted to the dotted line position shown in Fig. 5.

The contour panels designated by the assembly numeral 6I] include a front panel 6|, rear panel 32 and two side panels 63 and 64. Each of these panels is made of sheet metal having a vertical web 66, reverse bends or folds 6l and 68 at the bottom and top and upwardly and downwardly turned rims 69 and 15. 'Ihese rims have spaced notches 'II shown as V shaped. By this construction there are thus formed channel guides on the outside of the web of each contour panel and in each guide channel designated by the assembly numeral l2, there are two extension strips I3. Each strip is preferably formed of sheet metal of a flexible nature and theyare inserted from opposite ends of the channel guides. Each strip has a reverse end hook 'I4 outwardly bent so that the hooks of adjacent corner extension strips may touch or be in close proximity. They are then held in place by a locking corner piece 'I5 (note Fig. l). Each corner piece has a vertical web I'6 with two inturned hook-like edges ll engaging the hooks 14 of the extension strips. These locking corner pieces are inserted vertically and may be removed by the same motion.

A pocket engagement of the extension rods and the contour panels is constructed somewhat asfollows, note particularly Figsl 1, 2 and 4. On the back of each panel, that is, attached to the web 69, there are a series of vertical tubular pockets 8 I. These are formed by preferably metal strips 82 secured at their vertical edges to the back of the web. They may be somewhat rectangular or curved to form vertical spaces 83. It; is through these spaces that the finger end 84 of each of the extension rods extend vertically.

Some or" these pockets are made larger than the others considered lengthwise of the contour panels to allow for a iiexing movement as hereunder detailed and in such pockets there is formed a horizontal slot 85 through which may be extended the locking horizontally bent end 86 of the upwardly extending; ngers. In making the assembly the nger with the bent locking end is inserted upwardly through the bottom of a pocket, the end 88 being parallel to the web of a contour panel, then the rod with the iinger 84 is turned at right angles so that the locking end 86 extends inwardly substantially at right angles to the contour panel. The extension rod may then be tted in the guide tube or groove of the body block.

As above mentioned the pockets engaging the ngers 84 of the extension rods are made of different sizes, note a small sized pocket 90 and 9I is at the center of the front and rear panels 6I and 62 as this forms a center of flexing and on each side the pockets 92 and 93 are elongated to permit a slight movement of the lingers in the pockets. In the side panels 63 and 64 there are small pockets 94 and 95, these being preferably oiset one from the other and large pockets 95. There should always be a large pocket adjacent the end of each panel. It is to be understood however that the rods are to a certain extent ilexible to allow bending so that the contour panels-may be properly flexed. If desired a coverplate |00 of metal may be secured to the bottom of the body block and in this the guide grooves and the guide tubes for the extension rods.

In the manner of using my invention as above described, in the normal operation the contour panels with the extensionfrods are pressed inwardly so that they are in close'proximityto the edges of the body block as shown in Fig. 2. At this time also the extension strips 1.3 are thrust inwardly in their guide channels formed on the ,contour panels, the locking corner pieces "l5 are preferably in place connecting adjacent extension strips. To t the `device for instance to a 4chair or a construction for which a cushion is to be made, the corner pieces 75 are preferably removed, the front, side and rear contour panels are pulled away from the block, the spring clips 5i) having been loosened. This pulls the extension rods outwardly from their guide 4grooves or tubes, the `panels are flexed together the de-r sired contour of the sides, front and back of the cushion. Usually the side panels are symmetrical as to the body block but not necessarily so. The extension rods are then preferably locked using the locking clip 5I) voperating on the locking bolt 3B causing its keeper 39 to engage the underside of each extension rod. The extension strips 'i3 are then pulled outwardly and are flexed or pulled out straight according to the vshape of the corners of the cushion to be made and when -in proper position the corner locking .elements 15 are interlocked with the locking ends 'I4 of each extension strip, thus causing the contourpanels with the extension vstrips together with the locking corners to form an outline of the cushion v for which the material is to be cut. It is to be noted that the whole operation-is carried out with the device tted or used in connection with an article of furniture such as a chair, davenport or the like. As above mentioned the small 'pockets such as 90 and 9| retain the portion of the contour panels towhich they ae connected substantially in alignmentl with the guide tubes lor the various guide grooves of the block but the larger pockets indicated for instance at 92 permit a certain looseness so that the contour panels may be readily flexed withoutbending the extension rods, however, when these rods are pulled outwardly from the body aconsiderable distance they will flex to a' limited extent. The ready iiexing of the contour paneIsis-obtained by providing the notches such' Ias 1|. These cut away a suiiicient amount of the upwardly and down-turned flanges or rims such as 79 so that the main flexing is in the web 66`and the upper and lower edge portions of the guide channels for the extension strips 'may' follow the contour of the webs of eachcontour panel. As above mentioned the contour panels may be parallel to the side edges of the body block. They may have a convex curve considering the outer contour ofthe cushion. They can be bent to the concave curve or a reversejcurve 'including both concave and convex portions. Thus the extension panels may be shaped or flexed to include many shapes for the edge of av cushion to vbe made from material cutwith the aid of my template or cushion form.

In Fig. 6 I illustrate a, modification of the locking bolt and clip assembly. In this case the bolt with the keeper end is the same as shown in Figs. 4 and 5. In this case however the lowerinut |05 is preferably fiat and is engaged by .a swivel plate or disc |06 having diametrically opposite nstub shafts |01. v'Ihelocking-clip I I0 has a iiat 4.strip an upturned finger-grip end ||2`and two vspacedl ears |13. These ears are provided with a perforation journal for the stub shaft 18. The ears have a rounded edge ||4 facili- 5 tating tilting upwardly. The locking bolt 38 iS in its raised or'locking position when the clip 410 is inthe position shown in fully lines in Fig. 16 and is loosened when this clip is tilted upwardly as shown in dotted lines. It will be -understood that a `number of other types of clips Ycan be used to locky and tighten the locking bolts inrelation Ito the extension strips. For convenience-of .handling the ldevice I Amay have one or 4more handles H5 secured to the top ofthe body 15 .block Y f In Ffigs..-7 and 8 I illustrate another type of flatch. This employs a vwedging disk |20, this having prongs to engage in the wood block. Such vdisk has opposite raised or cam surfaces |2| with -gg peripheral top `surfaces l|22 between the ends of the raised or cam sections. A lever bar |23 has :aperfora-tion through which extends thepbolt 38, such .bolts having nuts and if desiredlock nuts vengaging the upper surface of the lever bar. This .lever baris 'preferably rounded on .the r.lower edge. 'Therefore when occupying the position xshown in Fig. 7 withxthe lever bar resting on the depressed surface |22, the locking bolt is in its lowered position with the keeper end 39 loosened fromV theV extension` rod but when turned into the dotted line position of Fig. 7 with the .lever-bar raised by fthe cams |.2|, the keeper is brought into locking relation with the extension Various changes maybe made in the details of V.the construction without departing from the spirit .-or scope of the invention as ipended claims.
