To all whom t may concern Be it known that I, WILLIAM H. FRENCH,

p a citizen of the United States of America,

residing at Detroit, in the county of lVayne and State of Michigan, have invented certain new and useful Improvements inIroningoards, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to an ironing table and to an arrangement thereof whereby rigidity of the supporting means is afforded through the 'peculiar construction which places the parts under such strain that they are locked rigidly with no slack and no tendency to work apart.

The invention consists in thematters hereinafter set forth, and more particularly pointed out in the appended claims.

In the drawing,

Figure 1 is a view in side elevation of a table that embodies the invention with a dotted diagrammatic additional view showing the position assumed by the parts that support the table just before complete eX- tension;` i

Fig. 2 is a view of theunderside of the `table with the parts in collapsed position;

Fig. 3 is a view of the rear-leg of the Ai-table;

Fig. 4 is a view in detail of a locking slot;

Fig. 5 is a view in detail of a brace hinge construction and Fig. 6 is a view in detail of a front construction.l

As herein shown, an ironing board 1 of suitable shape has at its outer end a depending block 2 suitably arranged thereon with a. pivot pin `3 extending entirely through the same. A pair of brace legs 4: extend from the block to which they are secured by the pin, and each have a portion 5 that is beveled to bear solidly against the table 1 ahead of the pivot when the device is fully eX- tended. A suitable cross tie 6 connects the low-.er end portions of these brace legs.

A pair of divergent members 7 that form an upright frame when extended, are connected by suitable cross'pi'eces 8, and have inner beveled faces 9 at the upper end that, where they are pivoted on the pin 3, frictionally bear against the outer faces of the brace legs 1 and thereby not only maintain the parts in close relation without any play tending links 13 which in turn are pivotedv as indicated at l1 to a depending block 15 carried by the members 7 and cross bars 8. Slots 16 on the proximate faces of the brace legs 11 are engaged by the projecting end portions of the pin 12 and each has a locking notch 17.

The parts are so disposed that in extending thedevice, as indicated by the dotted lines in Fig. 1, the beveled faces of the pro Jecting portions 5 of the brace legs 4 bear upwardly against the face of the table as the final position of the parts is approached. By putting suiicient pressure on the parts, the pin 12 is forced to drop into the notches 17 and when this is done the beveled faces of the portions 5 of the brace legs are sprung into close contact with the lower face of the board. This adjustment is made such as to take up all the slack in the .parts and re* quire some force to bring the legs into posi tion with the notches 17 engaged. T he spring of the material of which theparts are'made, permits this. To release the device it is only necessary to raise the links 13 which consequently moves the pin 12 out of the notches 17 and permits the pin to slide down the grooves 16 and thereby allows the supporting parts to fold up against the table.

As a result of this construction, a very simple and e'ective support for an ironing board is obtained that not only holds the table in position when extended but locks the parts firmly without any special locking or tension producing members.

Another very obvious advantage is that with one motion the operator can swing the supporting members into extended position and snap them, so to speak, interlocked rigidly without the necessit)v of the tightening up of any screws or like holding members. The release is likewise effected with a. single movement.

Obviously. changes in the details of construction inay he made without departing from the spirit of my invention and I do not yio care to limit myself to any particular form or arrangement of parts.

What I claim is l. An ironing table comprising a board, a pivot block on the under side thereof, a pair of brace legs embracing the block to which they are pivoted with the portions forward of the block adapted .to bear against the table when the legs are extended, a frame pivoted on the block in frictional engagement with the brace legs which it embraces, the proximate faces of the brace legs having longitudinal slots terminating at the uppcr end portions in lateral recesses, a pair offlinks pivoted at the forward end to the frame, an arm swinging from the table, and a pivot pin extending through the rear portion of the links and the lower portion of the arm into the slots of the brace legs, the parts being proportioned to force the forwardly extending parts of the brace legs firmly against the board when the brace legs are sprung sufficiently so that the pin enters the lateral recesses of the slots.

2. An ironing table comprising a board, a pivot block on the upper face thereof, a frame swinging from the pivot block, an arm pivoted at the upper end to the under face of the board and swinging therefrom, links coupling the arm and frame to main! tain them in parallel relation, a pair of brace legs pivoted at the upper end to the pivotal connection of the frame and block between which they are interposed in frictional engagement with both, the brace legs having longitudinal slots on their proximate 'faces with lateral recesses at the upper end portions thereof, a pivot pin coupling the links and arm and having a sliding engagement in the slots of the brace legs, the parts being proportioned to permit the pins to drop into the recesses of the slots when' the parts are in open position and the brace legs are sprung, and the portions of the brace legs that extend beyond the pivot past the frame having beveled faces that bear upwardly firmly against the under face of the board when the pivot pin engages the lateral recesses ofthe slots the pin maintaining the brace legs in tensioned position.

3. An ironing table comprising a board, a pivot block on the under side of the board, a pivot pin extending from each end of the block, a frame having divergent side members that are pivoted on the pin, an arm swinging from the underside of the board, links connecting the free portions of the frame and arm` to swing in parallel relation, a pair of brace legs in frictional engagement between the ends of the blocks and the swinging frame members on the pivot member thereof with portions eX- tending ahead of the block and adapted to bear upwardly against. the face of the board, there being longitudinal slots in the proximate faces of the brace legs terminating at the upper end in lateral recesses and a pivotal connection between the links and arm that plays in the slots and locks the parts rigidly in supporting position when the brace legs are sprung sufliciently so that the pivotal connection engages into the slot recesses.

In testimony whereof I affix my signature in the presence of two witnesses. WILLIAM H. FRENCH.
