The object ofmyinvention-is to provide an ironingtable, mounted upon a collapsible support, with a gravity lock arrangedrigidly 'to fastenthe elements of such support in extended position by the mere act of spacing I theironing board portion of such table from the floor when the collapsible support is arranged beneath the board. Such gravity lock is further proportioned and arranged to release such elements when theu-table is arranged with the supportabove the board.

Thedetailsof construction and mode of operation of an: ironing board. embodying my invention are illustrated in the "accompanying drawings, in which:

T Fig. l is a side elevatlonof such table with portions broken away to show the gravity Fig. 4 is a of theigravity locking devicein engagingrpol lapsed against the under locking device for holdingthe-supporting-- sition; and

My improved ironing table comprises a board a mounted upon a collapsible support.

' Such support comprises a rear'leg structure b composed of two spaced members 1) connected by two horizontal slats 0 and 0 and reinforced by slatscQand 03 extending longitudinally of such legkstructuresbh A diago'nal: crutch d, comprising two converging members d'is fastened'to the-under surface of'the ironing board a upon-a shaft or pivotpin f, upon which the leg bis also pivotalily connected to the board. Such plvot or j "tial thickness and the head n3- of such end "is tapered inwardly toward such hook. Such shaft pin 7 is held by cleats e dependingfrom theunder surface of the board-a, and such pivot pin" f extends transversely of'such board. 1 1 v The-"converging members d of the diagonal crutch d are connected at their point o 50 convergence by screws or bolts 9. and are spaced apart at such. pointby a. spacer h.

Intermediate the ends 10f such crutch two spaced guide rods '5 are locatedspaced apart to define a groove if between them, extendlng laterally of the members 01.

A jointed brace member 7' is pivotallyfas tened at one end to the board a andpivotally fastened at the other to the leg 6, the-pivotal connection to'the boardbeing made thru ,a. pivot pin k carried by pendent cleats 7c,

and the pivotal connection to the leg I) is 1 .made thru a pivot pin Z.

When the collapsible support is extended, one element j. of such brace member j extends substantially horizontally and the other element 7'2 extends vertically. Such elements are connected together by a fitting m, which straddles the element j,.as shown in Figs.

4' and 5, .the webs m extending, downwardly along the sides of the" latter. Extensions of m2 and m3 of such webs m extendabove I and below such element 7', a pivot pin 0. extends thru the ears m2 and the end of the element j2, which is thus connected to the element j. i v I f,

Theears m3, which'extend' below such ele--v ment j, serve as stops for engaging one of such transverse members i when the support is arrangedin extended position, which engagement locates the parts of such support. A gravity latch 01. is pivotallycarriedbetween such ears m8 upon a pivot pin p, such pivot pin passing. thru such gravity lock intermediate the ends of the latter, but at one side of the center of, gravity thereof. 7 The heavier end n is weighted suiiicientlyto hold up the opposite hooked end'ni against the under surface of the element j? and in en- "gagement with the transverse member 2" when the support is tionh v v .As;is shown in'Figs. 4: and 5, the hooked end n2 :of such gravity latchn is of substan-' arranged in extended positaper thus tends toguide the gravity latch of I the member iwWhBIl' the parts are extended and PATENT OFFICE table is to be collapsed without'turning .it upside downrelative to the position'shown in Fig. 1, such latch can be disengaged and the parts moved into collapsed position merely by gripping such tapered end n3 an d drawing it toward the pointed end a of the ironing board, the table during the operation being supported by the squared end a2 of such board.

The operation of setting up such collapsible support consists merely of spacing the board a from the floor and arranging thesupport beneath the board. This permits the leg'b and the crutch cl to swing downwardly counter clockwise about the pivot f, as the parts are shown in Fig; 1 and to arrange the jointed member j in the position shown in the latter. hen the leg Z) hangs pendent, the gravity lock engages the transverse member i, as shown in Fig. 4, andthe whole is rigidly set up. The setting up of such support may'also be accomplished by resting the board (1- upon its squared end a2, in which position the parts will swing into extended position. The board can be collapsed, as has previously been explained, either by turning the table upside down, that is, with the support above the board, in which position the gravity lock is arranged to release the memher i, or else by supporting the table upon the squared end a2 of the board and gripping the tapered head 113 of the gravity low: a and drawing such lock toward the pointed end a" of the body. If the latter. mode of operation is used, the pull upon the gravity lock n pivots the lock clock-wise, as viewed in Fig. 4, to release its engagement with the member 6' and then closes the jointed member j and pulls up the leg I) and. crutch (Z together therewith. T he latch a is proportioned so that the weighted end 11 swings into abutment withthe under surface of the element when the hook'e'd end 112 swings out of engagement with the member 2' andthus serves to limit the degree of pivot about the pin 0, as is shown in Fig. 5.

I claim:

1. In an ironing table, an ironing board and a collapsible supporting frame for the latter, said frame comprising a leg, a diagonal crutch and a jointed brace member, the leg and diagonal crutch being. pivotally connected to the board at one end of the latter and the jointed brace member being pivotally.

latch carried by the brace membensaid latch having its center of mass arranged eccentrically to its pivotal mounting and provided with a hooked end adapted to be swung toward and arranged to grip the laterally arranged member when the latter is in abutment with the stop and the supporting frame is arranged beneath the board.

2. In an ironing table, an ironing board and a collapsible supporting frame for the latter, said frame comprising a leg, a diagonal crutch and a jointed brace member, the leg and diagonal crutch. being p ivotally connected to the board at one end of the latter and the jointed brace member bein pivotally connected by one of its ends to tlie middle ofthe board and by the other to the leg, a

laterally arranged member carried by the crutch andastop carried by the brace member with which stopthelaterally arranged member abuts when the supporting frame is fully extended, apivotally mounted gravit latch carried by the brace member, said latch having its center of mass arranged eccentrically to its pivotal mounting and provided with a hooked end adapted to be swung toward and arranged to grip the laterally. arranged member when the latter is in abutment With the stop and the supporting frame is arranged beneath the board, said hooked end being proportioned to swing free of and be disengaged from the laterally extending member under the influence'of the eccentric mass of said latch when the supporting frame is arrangedabove the board.

3. In an ironing table, an ironing board leg and diagonal crutch being pivotally connected to the board atone end of the latter and the jointed brace member being pivotally connected by one of its ends to. the middle of vthe board and by the other to theleg, a laterally arranged member carried by the crutch and a stop carried by the brace member with which stop the laterally arranged member abuts when the. supporting frame is fully extended, a pivoted latch carried by saidbrace memberadjacent the stop, the latch having a hooked portion at one sideof its pivot and a weighted end at the otherproportioned to swing the hooked portion towards the brace member and to, engage the lateral member when the latter is arranged. in abutment with the stop. a a a 4. In an ironing table, an ironing board and a collapsible supporting frame for the latter, said frame comprising a leg, at diagonal crutch and a jointed brace member, the leg and diagonal crutch being pivotally connected to the board at one end ofthe latter and the jointed brace member being. pivotally connected by one of its ends to the middle ofthe board and by the other to the leg, a laterally arranged member carried by the crutch and a stop carried by the brace memher with which stop, the laterally arranged member abuts when the supporting frame is fully extended, a: pivoted latch carried by said-brace member; adjacent the, stop, the
