AARON M. SPRINGER,

OF PORTLAND, OREGON, ASSIGNOR TO OREGON WOODENWARE MFG. CO-, A CORPORATION OF ILLINOIS.

IRONING-BOARD.

Application filed may 6,

To all whom it may concern Be it known that I, AARON M. SPRINGER, citizen of the United States of America, and a resident of the city of Portland, 1n the county of Multnomah, in the' State of Oregon, have invented certain new and use: ful Improvements in Ironing-Boards, of which the following is a specification, reference being had to the accompanying drawin s.

Idy invention relates to improvements in ironing boards of that general descr1 tion set forth in my apglication for nited States Letters Patent erial Number 203,99a filed November26, 1917. 7

Among the various objectspf my invention, those regarded as most important are the production of improved mechanical efficiency in such a device and the promotion of economy in the manufacture of the article. The means by which those ob ects referred to are attained will be best understood from the following specification wherein that which constitutes my invention is first described in detail and afterward succinctly set forth in the appended claims. 1

In the accompanying drawmgs,

Figure I is a side elevation of my board having its supporting members expanded to the several positions which they occupy when the board is in use. I

Fig. II is an end elevation of the subject matter of Fig.I.

Fig. III is a bottom plan view of my device complete, showing the supporting members in the position against the bottom of the board which they occupy when folded.

Fig. IV is a side view of one of the brace legs of my device, detached. I

Fig. V is a detail medial, longitudinal vertical section of a portion of the subject matter of Fig. II.

Fig. VI is an illustration in aggroupment of one of the brace ends.

Fig. VII is a View of the middle hinge shown in Fig. V, taken at right angles to the view shown therein. I

Referring to the numerals on the draw; ings, 1 indicates an ironing board proper which is preferably made of wood, and may be of any usual or preferred shape and dimensions suitable for the purposes required of it.

Upon the bottom of the board 1, and "op- I affords simple and effective means .ally securing each leg to the board with Specification of Letters Patent. Patented Nev, 16 1920 1918. Serial No. 332,937.

eratively secured to it so that they may be conveniently folded a ainst it when the board is not in use, provide an assemblage of supporting members, comprising outside legs 2 and 3 which cooperate as a Hair, and a third or intermediate leg 4. he legs 2, 3 and 4 constitute when expanded a tripod support for the board 1, and are adapted to be expanded into 0 erative positions as shown in Figs. I and 1 b a pair of braces 5 and 6, operatively exten ing between. the legs 2 and 3, respectively,

and the bottom of the board 1, and a pair I of tension rods 7 and 8, connecting the free end of the leg 4 to the legs 2 and 3, respectlvely, substantially at their respective points of connection with the braces 5 and 6.

I prefer to secure the legs 2 and 3, re-

. spectively, to the bottom of the board 1 by any suitable means which will admit of such oscillatory movement of the legs as will permit them to be expanded to the position whichv they occupy as shown in Fig. II, or to be closed as indicated in Fig. III. Bolts or rivets 9 passing through the legs 2 and 3, respectively, and a base plate 10 of a hin e jaw 11 %or pivotfreedom of movement about the longitudinal axis of the member 9. A chafing plate 12, against which the base plate 10 may wear is preferably secured, as by terminal tangs 13, about the member 9 to the brace to which it belongs. Y

The hinge jaw 11 fits snugly between jaws 14 of a hinge member 15 secured as by a bolt or rivet 16 to the bottom of the board 1, a pintle 17 being employed to unite the jaws 11 andthe jaws-14, respectively. By

the hinge mechanism last described and which is shown more particularl and on enlarged scale in Figs. V and, II, two movements of the legs 2 and 3, respectively, are provided-in order to accommodate the movements of those legs to the actuation imparted to them by the cooperation'therewith and between each other of resilient brace- legs 18 and 19.

To secure such cooperation with thelegs 2 and 3, I prefer to provide transverse brace- legs 18 and 19 that are in efl'ect parts of the legs 2 and 3, being secured at their lower ends to said legs, respectively, as by bolts 20 and 21, respectively. The upper ends of the brace-legs converge to a point close to the bottom of the board 1, where they are pivoted as indicated at 22 preferably to a cross-bar 23 as by aid of an intermediate hinge member 25, secured to and projectin downwardly from the bottom of the boar 1 between lateral hinge members 26 and 27, secured to the legs 18 and 19, respectively. By reason of their disposition relatively to their-respective legs 2 and 3 'and to the board 1 the brace- legs 18 and 19 aremade to contribute to the rigidity of the said legs in service, and to the firm support of the board.

Through the disalinement of the pivotal connections 22 and 9, respectively,.in combination with provision made of the pintles 17, means are provided whereby the legs 2 and 3 may be automaticallyexpanded and closed solelyby a pushing or a pulling force applied to the braces 5 and .6.

The leg 4 is hinged to the bottom of the board 1, preferably by aid of a pintle 30 passing through a clip 31 secured, as by a screw or bolt 32, to the bottom of the board 1. The pintle 30 is preferably located close to the axis of the cross-bar 23 and the leg 4 is provided with a toe 33 to engage a stop block' 34 on the bottom of the board 1, when the board is set up, the length of the leg 4 being such as to bring its foot 35 near] vertical to the end of the board 1' whicfi it supports.

The tension rods 7 and 8 extend from a point of connection 39 with the leg 4 near its foot 35 to the bolts 20 and 21, respectively, to which they are united in effect by a loose connection, for example chains 40 and 41, respectively, after the manner de scribed in my previous application aforesaid. The chain ends 40 and 41 of the rods 7 and 8 respectively, preferably engage hinge terminals 42 and 43 secured to the respective braces 5 and 6.

In like manner, the relative lengths of the legs 2 and 3, and 4, and of the rods 7 and 8 should be properly proportioned and adjusted to the relative lengths of the braces 5 and 6 and the brace- legs 18 and 19 in order to effect a,rigid assemblage of the members when these braces are adjusted to their holding positions. This position is determined by an engaging member 47 which may-consist of a cleat of wood secured to the bottom of the board 1 and preferably notched as indicated at 48, to engage and hold the ends of the respective braces 5 and 6 substantially as described in my aforesaid application. The braces 5 and 6 are likewise preferably united neartheir free ends as by a yielding, preferably, metallic bar 50, adapted from its yielding nature to afford the slight hinged effect described in my previous application aforesaid as desirable between the bars to accommodate expansion of the legs 2 and 3. Engagement which they engage when the board is set up. A release and reverse movement of the braces 5 and 6 will serve tov close the le s to the folded position shown in Fig. 11 Also as in my previous application aforesaid, when theends of the braces 5 and 6 are adjusted to the notches 48 they serve to secure the various members of the supporting mechanism in operative position from a single point. But an important distinctive feature of my present invention in comparison with what has preceded it, is that the operation of opening as well as of closing the legs 2 and 3 is as direct and-positive in the one operation as in the other. More over the truss effect of the combination is modified as to the position of its severalconstituent members and improved thereby. The modified truss effect referred to is twofold and is well illustrated in one aspect in Fig. I and in the other aspect in Fig. II. In Fig. I the effect referred to is found in the relative disposition of the board 1 and the brace 5 (shown as one of two), and, in like manner, the leg 2, in combination with the bracelegs 18 and 19. The members 1, 5, (6) and 18 (19) form a triangular truss member as shown in Fig. I in which the angle 5, 20, 18' is intersected by the leg 2 which acts as a cross brace. The stiffening effect upon the whole structure is in practice very considerable. A like result with transverse stiffening effect is derived from the disposition shown in Fig. II of the brace-legs 18 and 19with respect to the legs 2 and 3, and the positive connection between them, respectively, and between the said leg braces and the board 1.

\Vhat I claim is: g

1. The combination with a board and its supporting mechanism, comprising a pair of legs and an independent double hinge connection between each leg and the board, of means for actuating in part said double hinge connection and thereby expanding the free ends of said legs automatically operative whenever the legs are brought in a transverse plane substantially at right angles to the board.

2. The combination with a board and its supporting mechanism, comprising a pair of legs and a double hinge connection between each leg and the board, of brace-legs secured to said legs and hinged to the board, respec' tively, and means whereby the bringing of the legs into a transverse plane substantially at right angles to the board causes the free ends of the legs to expand.

3; The combination with a board and its supporting mechanism, comprising a pair of legs and a double hinge connection between each leg and the board, of brace-legs secured to said legs and hinged in disalinement with said hinge connections to the board, respectively, whereby the bringing of the legs into a transverse plane substantially at right angles to the board causes the free ends of the legs to expand.

4. The combination with a board and its supporting mechanism, comprising a pair of brace-legs and braces extending to the'board having one end of each secured to said legs,

respectively, and their other ends hinged together and also hinged in fixed pivotal relationship to the board.

In testimony whereof, I have hereunto set my hand in the presence of two subscribing witnesses.
