My invention has referei'ice to improvements in ironing boards .oftlre folding variety, and its objects, generally stated, are:

Toprovide a'device ofthis character,havm5 ing, in. connection, with asingle and folding leg, a pair of folding legs which are divergent when operatively disposed but Which automatically converge when the legs are placed in closed positions, and all foldable within n1 the compass of and against the body portion, thus adding" to its'compac'tness and serving to support the. legs and connecting parts against strain when the board is subjected to handling while in folded condition Further, to provide a board which maybe instantlyadjusted to a height which will aceommodate'it to'the requirements ofthe user;

Further, to provides construction in such a device which will permit all play to betaken -1.2 up in its pivotal connections, when in use, and thereby assureto the user at all times a substantialand solid -Working surface; and,

Further, such additional objects, adverb tages and capabilities as will later more fully msu appear. 1 i Inthe8.0001111)anylngdl't-Wlng Figure 1 is aside elevation of the device complete, and in open position; 1

Referring more particularly to the drawing, the body portion of the device, denoted as 1, is provided, in the present embodiment of the invention, with a portion 2 reduced in width, which is useful in; ironing sleeves, or the like, but as will be obvious, it

Ii may be of any other suitable form. A pair of hangers, each designated as 3, are-bolted to the body portion'and disposed in spaced relation. Said hangers, in common with the other paits't'o be described are located on or extend from the undersidelof the body portion. WVhat term as the single leg of the device, generally denoted asi, consists of a pair of members 5 bolted together, as at 6, to form at one end a leg which is provided witha beveled foot portionT, and bifurcated at the other end and pivotally mounted in said hangers, as is more particularly -illus-' trated in Fig, i, by the bolts 8.

A pair of bracket members, of metallic construction, are secured to the body-portion and adjacent the hangers, the same beingoppositely disposed and extended longitudinally of said portion, in spaced parallel relation. Each is of identical construction, and comprises a body member 10, whiohcarries a right angular portion 11, through which thememher is secured in place, asindicated in Fig. 2. Said member is also provided with an elongated slot 12, horizontally disposed, which terminates at one end in a curved slot 13 havinga plurality of teeth 14 extending in a like curve and spaced away from the lower edge thereof; J

Arod 15, having at each end retainer-:16

is slidablymountedin the members last de scribed and isoperable therein in a manner which will presently appear. Aslink 1 7, is

fixedly secured at'one'end tosaidrod, and

centrally thereof, as more particularly appears n Fig. 4, and is reduced in thickness at the other end, as at 18, to provide a con venient handle, the link being held in a'horizontal position against the ,bodyportion by the keep'er19. This link, including itsfunctions and mode of operation,will be" described with more particularity hereinafteri o As detailed in'Fig; 2, a. pair of legs, e ach denoted as 20, areswingingly and slidably mounted on the rod 15 by the scre'wl eyes 21,

secured inthe upper endof' each leg, said legs being disposed on either side of the link 17, and the head of the link, immediately connected with the rod, serving as a spacing element therefor. Each legis pivotally connected with the leg 4 by a bolt 22, secured in place, and bears upon and rotates overa wedge-shaped block 23, fixedly secured to the last-named leg. The pivotal connections lastdescribed are designed to permit a slight play in. the legs so that they willworkrfreely.

1 device.

As it may be noted in Fig. 1, when the board is in open and operative position the rod 15 is engaged on either side by a pair of oppositely disposed teeth 14, which serve to hold the same securely insaid position. When it is desired to vary the height of the device, the adjustment therefor may be effected by the user grasping the handle 18 of the link, when, by reason of the clearance between said teeth and the slot 13 and the fact that said rod is fixedly secured to the link, the link may be manipulated by pressing the handle 18 toward the body portion so as to disengage the rod from the teeth and the rod may be then brought forwardly so as to engage another pair of teeth, thus lowering the board.

The plurality of teeth provided for this purpose and disposed'as they are in a curved line extending downwardly as shown in Fig. 1-,-in cooperation withthe pivotal connections of the legs and the other connecting "elements shown and described, will permit a considerable variance in the height of the The board may be folded by releasing said rod from the teeth with which it is en gaged, through manipulation of the" link as just described, and forcing the rod, by said link, to enter the horizontal and parallel slots 12, when the legs may be collapsed. The

link-also serves to hold the rod in free sliding engagement with said slots and likewise the slots 13, and is instrumental also. in keeping the pair of legs in alignmentso that they can be folded without binding or inconvenience. As the folding operation proceeds,

said pair of legs, by virtue ofthe wedgeshaped blocks on which they act and their swinging and sliding connections with the rod, will gradually converge at their-lower ends and diverge attheir upper ends, and when the-board is completely folded, said legs,

together with the single leg, willoccupy the positions shown in Figs. 4 and 5, and, wherein thelegs are, located within thelimits of the "body portion and rest thereon. Then the device is thus folded, it may behandled, or easily placed in condition for shipping, without danger of springing the legs orconnection.

The device may be adjusted for height also,

tions, and it is in'a most compact and convenient-form for these purposes. r l

Theboard may also be folded in other ways, as for instance, it may be placed on its larger end, to relieve the legs of weight and tomake the linkmore accessible, and on release of the rod from the teeth securing it in place, the legs will readily fold up against the body porby the user placing a foot against the free end'of the single leg, whenthe board is in operative positiomand raising the body portion until the rodlis free of the teeth in which it is engaged, then when the user permits said leg" to slide forwardly a Shortdistance the of the cycle of operations described.

The spread of the legs is the chief factor in determining the height of the device, but said teeth, inaddition to their function as catch elements for the rod, also serve, on account of the curved line on which they extend as shown, to compensate for the difference in the lengths of the single leg and the pair of legs as they extend upwardly from their pivotal connections each with the other, and'the positions they assume in their pivotalmovements. curing-and maintaining the body portion in a level position when the device is operatively disposed, and as the legs have a three-point.

contact with the floor on which they stand,

they will accommodate themselves to a sur-. "face which might be somewhat uneven and Said teeth are thus important in se-.

stillsupport the body portion in said position. The legs, being triangularly arranged, re-

ceive the stresses and strains incident to the use of such a device mainly in a longltudmal direction, and they, in" conjunction with their connecting elements, asdescribed, obviously will take up lost motion in the parts, caused through wear or otherwise, when pressure is applied to the body portion, and thus provide a solid and practically permanent basis therefor. p I

Also, the disposition of the parts issuch as to afford a body portion having an under side free from obstructions for the. ma or part of itslength, which makes the device particularly efficacious andhandywhen ironing dresses and large articles.

" Ghangesin and modifications of the construction described may be made without departing from the spirit of my invention or sacrificing its advantages, hence I ask that I be not confined to the specific structure set forth.
