` f `4 clarin.` (o1. :ss-12a) This invention relates to an full or toy size. i, l,

The object ofthe invention is the provision. of means holding. one leg that may be vplaced in two different positions corresponding to three different heights of the boardproper abovethe `floor ory other supporting surface. These. I means also function as alock locking the `legs of the` board in folded or collapsed position upon thelbottom side of the board proper so that theA entire struc--y ture may be handled or stored away in a narrow space without the legs spreading andhampering the user. l

The invention consists in the details of .construction whereby certain importanty advantages are attained and which will be described. I g

The novel features of my invention will hereinafter be particularly claimed.

The description is illustrated by the accompanying drawings in which:

Figure 1 is a .bottom plan view of the ironing board with the legs in position collapsed against the bottom of the board;

Figure 2 is a longitudinal central line 2-2 of Figure 1;

Figure 3 is a lcentral longitudinal section through the board with the` legs extendedthe ironing board of section on lowermost ends of which aregomitted and the latch set in a position giving the board the` maxi- Figure 4 is a section similar to that of Figure 3 with the distinction however that the latch holds f the legs in a position in which the height of the board above the floor is less than that of the preceding figure;

Figure 5 is a detail sectional view of the pivot means attached to the bottom of the board and to which one pair of the legs are pivoted;

Figure 6 is a transverse section on line 6-6 of Figure 4;

Figure 7 is a longitudinal detail section on line 'l-l of Figure 6 through the latch set in the position of Figure 4.

Similar reference characters are employed to designate similar parts throughout the figures.

The board proper B of moderate thickness is generally Oblong and has its longitudinal edges approaching one another towards the right hand end. Beneath the board and near the left hand right-angled end of the same are blocks 2 secured to the board by nails 3 or other fastening means. These blocks have aligned apertures 4 through which extends a rod 5 having ends protruding beyond the blocks and passing through apertures 6 in the upper portions of downwardly V diverging legs 1 which are ior connected at an intermediate point by a rod 8 and near their bottomv ends by a rod 9. .f I To the bottom of the board a latch IU is pivoted by a screw nail or other fastening means The latch is provided with a notch I2 extending parallel to the plane of the board and formed in the end remote from pivot II. Another notch I3 is formed in the bottom surface of the latch, between the pivot I I and notch I2.

Upon rod 8 is pivoted another shorter pair of legs I4 the upper converging ends of which carry a rod I5 while the lower diverging ends carry the rod I6. Owing to the fact that the leg structure I4 is shorter than leg structure 'I and passes through the latter, the former may be folded into the latter in which position the latch I0 may be turned to the position of Figure 1 in which the rod 8 is lodged inthe notch I2 and the entire board is locked together. If it is desired to use the board, the latch IIl is turned to the position of Figure 4, the board is inverted, the legs are unfolded to a crossed positionin which the rod 1 I5 can be lodged in notch I3. If the user finds the board inconveniently low, he may adjust the same to a higher elevation by lifting the board so as to disengage rod I5 from the notch I3, then turning the latch to a reverse position of Figure 3 in which he may rest such rod in the same notch now located on theopposite side of the pivot or in the end notch I2, if a still greater height of the board above the :door surface is desired.

Having described the invention what I claim and try to secure by Letters Patent is:

1. In combination with an ironing board provided with a stand on the underside thereof composed of crossed hinged legs foldable into one another and one of which legs is pivotally connected at its upper end to the underside of the board. a block rotatably connected to the underside of the board and provided with a notch in one end thereof and a second notch in its underside and between said end and the point of connection of the block to the board, said rst notch being engageable with the hinge of the legs for locking the stand in a collapsed position against the board when the block is disposed with said first notch facing toward the pivot of said leg to the board, a rod extending transversely from the upper end Of the other leg, and said first notch being engageable, in the same position of the block with the rod for holding the stand in one extended position, said second notch being engageable with the rod in said aforementioned position and in a second position of the block intermediate of their ends to, an intermediatev portion ofv the'rst pairof legs and in crossedrelationship, a rung connecting corresponding,v
