inetodamember st ii i d fi 1:1 1 .'-j: hi -aii l bati i is. impar -a: co tinuat on. .of my co p ending application, Ser;ial l t l 'o.- 691,602 wherein is described and claimed a structure of .QPQZQ ??%9PIni lll i% .gdevice by which the locking rod member or brace is releasably fastened to the front leg when the table is set up for use so as to prevent the legs from becoming folded accidentally, and enabling the user to unlatch the parts easily before folding them.

The present application-provides a somewhat similar system of bracing for the legs, yet arranges the locking bar and its latching device in a new way, whereby the objects of the invention are attained.

These objects are to simplify the construction, provide a supporting mechanism having stability, reducing the cost and facilitating the manufacture of the table.

My improvement, therefore, is found in the supporting structure arranged so that changing the board on a given set of legs can be accomplished easily and quickly and the shop assembly of these parts is facilitated, reducing the cost of manufacture.

My improvement also includes a novel means whereby the toggle-like locking member is enabled to latch itself in a straightened position and to make it easy for the user. to unlatch it and fold all the supporting parts by a single breaking-down movement of the toggle.

With these objects in view I have devised and invented the improved ironing table that is illus trated in the accompanying drawing and described herein, my claimed invention residing in the particular construction and arrangement of the toggle-like locking rod members and the manner in which they are hinged and connected together between the rear legs and the top of the front leg so as to provide a rigid framework that is capable of standing rigidly.

Tothe-ironing board 1 areihinged acentrally arranged front leg 2 anda pair ofispac ed rear legs 3.. Connecting-rods 4 are pivoted at.5 to the front .leg'2; near its foot and .to the. rear: legs in-g termediat'etheirends at 6. v "The toggleorlocking rod member. consists of two bars 7 pivotally cone-1 nected to the rear legs at 6. The bars 'lfconverge: forwardly and each is pivoted at 8 to one of the side bars 9 of a toggle member 10. The other ends of side bars 9 are pivoted to the hinges of leg 2, as shown at 11. The bars 9 are spaced apart a distance equal to the thickness of the front leg 2 so that when the parts are folded they will lie close alongside the legs 2. The member 9 swings forward and upward as indicated by the broken line in Fig. 1 to fold the table, and compactness for shipment and neat appearance when folded are thus attained. The longitudinal upper edges of bars 9 are parallel and are preferably connected by a suitable web member or Y spacer, as shown in Fig. 2.

Near the pivot 8 is an abutment 12 which is; struck up from bar 9 near its. upper edge, and v near its lower edge is a projection 13. The free end 14 of bar 7 is adapted to ride over the projection 13 when pivot 8 of the member 10 is pushed downward inthe manner indicated by the broken line in Fig. 1. The part 14 is releasably locked between 12 and 13 in the manner shown in Fig. 2 by a reverse or upward swinging movement of the joint 8, so as to hold the members '7 and 10 in the straightened position shown is prevented from going in Fig. 1 and joint 8 higher. Folding or extending is thus accomplished by .a single movement, and the table is designated-in the trade as a one movement ironing table; In the position shown, the parts ,7 and 10, together with leg 2 and connecting rods 4, constitute a rigid triangular non-racking truss frame structure that has its apex at 11 and rests on the floor at its lower corner 5, tending to keep the legs 3 upright. The self-supporting framework'wil hold that position while aboard 1 is being removed and another board is being put in its place and fastened .to plates 15 and 16 earlying the pivots for plates 3 and 2 respectively.

boards 1 which maybe appliedto the legs; can be done; conveniently: by using. a standard Legs 3 are prevented from pivoting about 6 as a center and the triangular frame 2, 4 and 7, 9 is prevented from collapsing and dropping to the floor by reason of the triangular shape of the frames defined by the parts 3, 4 and the floor, and by the parts 4, 2, 10, 7. A triangular pivoted framework can not be racked, so, barring sliding ofthe bottoms of legsi3 and Z on: the floor, the framework must retain its position without the board 1. Similarly, the frame 4, 2, 7 is rigid ture, and will not collapse. This general arrangement of the legs, together with the novel'* 7 toggle-like foldable locking; deviceexemplified by the structure illustrated in 2'ponstitutes BEDQW' and useful improvement in foldable ironing tables whereby a single breaking-down movement .of the toggle suffices to fold all the "supporting'parts; as

For rapid assembly in the factory the board l: canlbe' laid down flat on a flooror table and the legs, and a central front" framework, extendedasshown in Fig 1, can :be
