COMBINATION FUR-NI'IURE.`

Application led December 31, 1927. Serial No. 243,951.

In lurnishingi` a home, among the moet essential articles in the equipment are chairs. Ar very convenient although less oitten used article is a step ladder. A high-chair is an.- other requirement when very young persons are members of the household.

My invention relatesI to combination ltur- .nilure7 and its principal object is to provide in one unitary structure the elements necessary to transform the device, when the parts are in'operly arranged, into either one of three separate articles of utility,-a high chair, an ad ults chair and a step-ladder.

A further object is to so construct and fabricate the parts that thoserequired for either ot the three purposes maybe brought into functioning` position without detachinp; any oit the ind ividual parts employed i'orfthc other purposes enumerated.

l have illustrated the preterred embodi.- nient o'" my invention by the use of the accompanying: drawings, in which,-

Fig. l is a side elevation of the devirc shown as an ordii'iary household chair7 the eleniei'its used to convert the chair into other articles being stowed away or 'folded into inoperative positions;

'Similar reference characters are employed fragmentary elevation', partly to indicate like parts throughout allthe ditil'erent views et the drawings. y

'lheelements comprising ni'y ,invention are built around and operate in conjunction with the parts otan ordinary household chair, and, in combination with the latter and with each other7 provide the individual articles of household furnishings hereinafter to be described. f

, 17 l, represent the back legs and upright extended portions thereoit7 2, 2, the front legs and 3 the seat oli the changthe latter being` hinged at the rearward end. The usual. bracing` and tying means are shown iny the rungs end back-boards 5.

Suspended bet veen the upper extended portions oi'V the legs, 1y 1, is a double pantoggraph traine, each side consisting, when extended, or" one longvertical liront-.leg 6, a horizontal bar 7, and a vertical bar VS, together with a channel member 9 which completes the 'four-sided trame. i v

This member 9 has downwardly extending` ears 9 through which the parts are jointedly connected at points 1.0 and 11. The

' pantog'raph iframe, complete7 swings on the dowel '12 and when folded or retracted into inoperative position snugly tits between the two uprights'or leg' extensions on the legs 1.

A board 13 extends from one to the other of the horizontal bars 7 and serves :is the seat for the high-chair. On the upper end o1" each of the leg 1 extensions is a plate 1.4 havinga slot 1.) in which operates a trunnion 16 projecting inwardly from each ot the table side arms 17. The slots in these plates yhave ott-set portions at the top and bottom,-those at the top being on the back 'side` and those at kthe bottom on the it'ront side oli the slots.

Mounted on the under side of the highchair table 18 are spring-rods 19adaptable kof engagement with notches 20 in the upper ends of the legs G forthe purpose of holding;y the table 18 from accidental displacement from the pantog'raph frames. To f guide the rods 19 and control their outward movement there are provided slotted `brackets 21, having slots 22 in which the rods.,operatis-oue of these brackets beingr y provided on each side ol" the table. v

f' Then the rods 19 springy into engagement with the notches 20, the table is forced forwardly so 'that the trunnions 16 are then locatedv in the lower ott-set portions o the slots 15,which thus effectively ties the table `making connection with each of these bars,

to the frames and to the chair extensions 1 and prevents the lifting of the table by a child who may be seated in the high-chair.

The adult chair-seat 3 has holes 23 adapted to receive the trunnions 24 on the ,bottom ofthe legs G, so that when the frames are extended they may be held rinly against horizontal movement on the seat.

Beneath the seat 3, which may be swung` upwardly on the hinge pins 25,:is a bottoniboard 26, which, with the proper side and end members make a box, which provides a convenientV storage chamber, the seat 3 serving as the cover therefor.`

Swinging from each inner side of 'the legs 2, at 27, 27, is a horizontal bar 2S; also at 29, is a leg 30.` A bar 31, disposed in parallel relation te the bars' 28, makesV connectionk with the rungs 32 nd 3, and secured to the two bars 28 is a platform which serves as the lowest step inthe stepladder combination.

As is thecase with the high-chairV frame,

this step-ladder frame is collapsible, and the latter' may be housed between the two 2, 2 of the chair. To 'secure the p-ladner frame in its folded "position l provide trunnions in the seat 3Vwhich, when the frame is retracted, engage notches v36 in the ends of the bars 28,-the sea-t first being lifted until the frame is in place and then lowered, which effects the locating of the trunnions in the notches.

The pins 27 do not extend transversely from leg to leg of the chair but project inkwardly only so far as to provideproper support for the endsr'ofthe bars 28. They areshortened to allow the bar 31 to be folded between the legs 2 .without interfer-V ence. y

Inarranging to place the high-chair coinbination 1n Josition the leest are brought 7 nf l l upwardly, as seen infig.Y 6, and swung forl *Y into locked position on the frame. In con``V verse manner of operation the table may be ivardly until they assume a substantially vertical position, then 'lowered ,sothat the lifted and swung into inoperative position Awhile the child is still seated on the highchair.V

' Thelowest step in the step-'ladder coin! Vbination is put 1nV place by rst raising the seat 3 which'disengages the 4t'ri'ninions 35 from the bars128 andv swinging the frame vvoutwardly yuntil the legs reach vthe floor.

With theedevicearranged as a step-ladder,V

the seat13 is moved into extended position Awardly hinged seat said chai stance a chair fora boot-black. thc rece 7 tacle under the seat 3 being useful to store his implements and material whennot in use.

The manner of constructing the parts, th simple operations required to put eit" ero Vthe combinations into and the coinpleteness with which the attachments to convertvv devieeinto the-se combiimions may be housed and condensed, makes it a very convenient and serviceable article of household use.`

Having thus described inyinventicm, what I claim and'desire to secure by Letters Patentis lfln a device of the characterdescribed, comprising in coinbii'iation'a chair, a rearwardly hinged seat on said chair, uprA t extensions on the rearward end of said chair., a plateV on the upper end of each of said upright extensions having therein a relatively long, vertical slot piovided with a real-wa diy disposed off-set portion at upper end and a forwardly disposed oli-set portion at itsV lower nd, a table, arms extending from said ta and embracing l plates, a trunnion in each ef said arms adapted to engage jdie slof: in its adjacent plate, a pantograph frame l v hung to each of said upright ext a seat se eured to and extending fr one-"to the other of the said pantograph frames, nie ns support the free ends of said pento; frames on said hinged seat, and means to lock said table to said pantog'raph frames.
