This frame The mattress frame Il is made up of sideand lend angle'irons I8 and I9 suitably bridged by a screen network 2B held taut by tension springsv 2l, as is shown in figurev 2. rlhis yframe I'I has support arms 22 at its yfour corners which are pivoted to the end angle irons I9 by pivots 23.

The axes of these pivots extend lengthwise of the lOy ' structure. Conversely, the mattress frame is supmattress frame as is shown in Figure 3, thisA positioning of the pivots being to hold the arms 22 free from play in directions.l lengthwise of the crib as for purposes whichV will/hereinafter 4be apparent, As so mounted, the support arms 22 may be swung from retracted positions beneath mattress frame i'sl permitted when it is sup-V the frame into outward laterally extending posi;v tions andr vice versa, this retraction of the arms having a principall advantage in permitting Ya reduced overall sizeof the carton for packaging Athe frame for shipping, When in' outwardly ex-v tended positionathearms 22 have supporting 'engagement lwith the two rieidifyne brackets. 9. a'foredescribed.` and with two other brackets at theother Vtwo Cornersfof rthe crib which, forV the purpose, of standardizing' the` parts, are made identical with ythe rigdfyng brackets 9,.

` Reference being hadto Figure, it will. be seen thatfeach, rigi'difying` bracket,94 is secured to the end section I byscrews 25l and that it has three horizontal vertically spaced Vlugs :l upper andlower identical lugs 2t and an intermediate lug 2'?.

29at the'erid thereof which'is adapted'to. receive snugly the corresponding guide Vrod 5 to holdjthis rod rigid ,against sidewise play or movement (it will be understood that the apertures 29: in theA two. brackets 9. at the corners.v of'tlzie-clib4 adja- Acent the stationary side panel serve no. pur-'- `rpose in''t he present structure); Beside the` aper-l ture 2,9thje upper and. lowefr lugs 26 each have av pair effin-ner.V and outer apertures Yli and 3i.

A'l'.lhese r(aperturesare` received by th'eksupport arms 22j/in the variouspcsitions ofthe mattress-frame, `thelsupport arms, being?, for example, ofl a hook shape adapted toA fit `these apertures 'and to be interlocked. withY the lugs against horizontal play.

holes 30arf1d 3 Iy are `so positionedfthatwherl themattress frame is supported horizontally in either lower or'l Yhigher positions', the support varms 22 engage the outer apertures 3B ofA either the rupper or lower lugs as the-case may be; and

/ To. permit the mattress frameto-bersupported horizontally alsoY at ani interrnediate` level.`r and at different heights with a medium. inclination.. therek `are .provided the.. intermediate lugs 2l.

These. lugs have apertures 32 for receiving the t ends rofthe support arms 22 when the arms are in. supporting. engagement therewith. However, vthese apertures. arev elongated in the direction lengthwise/.olf the cribr so as to receive thesup.-

port arms 22Y both when theV mattressv frame is "heidV non zpntauyby thesegmtermediate iug'sand v .at an'inclinaton fromn thse'flues at Olne end f ofthe crib andv from either the 'upper orflower lugs 26at the` other fend 'of ythe crib, the' `amount ,of retraction ofthesuppcrt'armsfirom 'thef'crib end sections asfthex'mattress 4,fieuhe is movedjtjo t medium inclination being yinsufficient to permit [The lugs 26,are longer than the

intermediate lug

2,1,v and are each'provided with yan'` aperture y the support arms to be received in apertures in the intermediate lugs separate from those received by the support members when the mattress frame is held horizontally.

- Since the support arms 22 are free from play in the directions lengthwise of the crib and are adapted to engage the upper and lower lugs of the brackets 9 substantially without play in a horizontal plane, the mattress frame and its support means is effective to rigidify the whole crib ported without play, the freedom fromV lengthvwise play of theframe being particularly impcltantin obtaining a' well-constructed and com;- mercially suitablel crib. While some play of the ported from the intermediate lugs 2l, because Yofthe slot-like shape of the apertures 32, this play is vof such limited character as to be not particularly objectionable.

A It will bev seen thatr when the` support arms 22 are in theirputwardfelfective positions, asis dened by theabutment of thev arms against the horizontal iiangesof the end angle ironsV i9 of the'wm'attress frame4 they extend upwardly to forma;v hanger type of'support for the frame.

vThis permits the frame to be supported at lower levelsin the crib and 'thus gives a greater depth to the Ycrib as in respect of'thedistance from the fra-me tof'the top of the side panels.v

They cribarrangementY hereinabove describedv is of yparticularly simple Aform; yetV it has' the desirable features of adjustability ofthe mattress y frame and ofthe side -`panel, andi of being of a highly rigidfconstruction'in each of the various adjusted positionsL of 'theseparta' While I have hereindisclosedbu't one side panel, as being vertically adjustable, no unnecessary limitationof my invention to a crib havingbut one adjustable side' llzvjnel' is intended. Itwill, for example, be seen that' the mov'alcplel mounting ofthe panel'v 3 may be duplicated.' with rSp'ect tothe panel 2', and, that the'crib structure will yet be held an- 4gularly rigid, at* its corriers'by the, mattress frame and; support meansftherefor asy is hereinabove described,A

t Injligure 5 there isA shown a modification of my inventiclnv in "respect of the retractible support arms 'for the mattress frame. In 'acc'ordancewith this modification, the, mattress frame isv provided` with1

supportarms

3,5 atits corners which are' inthe shape of bars but which terminate in hooks 35' adapted for supporting 'engagement with'. the lugs of the, respective brackets 9. This

support rarm

distance equal to the lengthof the slots 3'Ij'be' tween ia. retracted position' beneath. the frame'and Aan outward "extended position for'supporting eneasement' withthe respective-brackets 9L thelarms being restrictedjto',slidinggmotion by the contact of the, tQDQedge 'thereof ,against Jthe'horizontal flanges Ofthe l'enti angle irons IQfof the frame.
