AUGUST SWANSON, OFCEDAR RAPIDS, IOWA.

IRONING BOARD.

Application filed September 20, 1921.

1 '0 all whom it may concern:

Be it known that I, AUGUST Swanson, a citizen of the United States, residing at Cedar Rapids, in the county of Linn and State of Iowa have invented certain new and useful lmprovements in Ironing Boards; and I do hereby declare the following to be a full, clear, and exact description of the invention, suchas will enable others skilled in the. art to which it appertains to make and use the same.

The object of this invention is to produce a folding ironing table adapted to be easily manipulated, and when set in position for use, to be strong, rigid, and immovable under the iron.

The invention is fully disclosed in the description and claims following, reference being had to the accompanying drawing, in which:

Fig. 1 is aside view of my improved ironing-board in position for use. Fig. 2 is a view of thesame from the under side, partly folded. Fig. 3 is a sectional view, longitudinal to the brace-holding cross-rod,

. showing detailsoi' the device for holding and. locking the brace-rods. Fig. 4: is a cross-section of the same, in the line of one of the brace-rods. Fig. 5 shows details of the brace-rod hinge and its connections.

In the drawing, the numeral 5 denotes an ironing-boarrfl of a familiar type, to which is attached a pair of cross-cleats or brackets 6, and to the ends of these are hinged the pairs oi? legs 7 and 8 for the head and foot of the board, respectively. These pairs of legs are connected by diagonal tie-bars 9 and 10, so as to give them lateral rigidity. For the legs 8 the ties may connect all on one side of the legs, but for other pair of legs the upper ends of the tie-bars connect with the inner sides of the legs, and their lower ends with the outer sides, for a purpose which will presently appear. The head pair of legs is more widely separated than the other pair, so that in folding the latter may :t'old inside the former. For stability the legs are all spread at the foot, special projection being given the legs which support the smaller end of the board, to prevent tipping of the same under the ironing pressure.

The repective pairs of legs are hingedly connected by diagonal and practically parallel tie-bars 11. These are connected, a

little way from the head-end legs by a rigid rod 12, the connection with the tierods being pivotal so as to permit the rod to turn. The rod is pierced at 12 by countersunk holes to receive the correspondingly headed brace-rods 13. The other ends of the brace-rods connect suitably with hinge-lugs 1a, and these are hinged to brackets 15 secured to a crosscleat 16. When the legs are folded down fiat against the under side of the board, as they may be, the brace-rods shde endwise through the cross-rod, as shown in Fig. 2. They also pass between the tie-bars 9, and in order that the latter may not interiere with the full movement of the brace-rods their upper ends are connected with the inner sides of the legs, as above mentioned.

When the table is unfolded for use the brace-rods act as struts, as well as ties, and lock the legs rigidly in their extended position. For this purpose the'cross-rod is provided with an enclosing .tube 17, which may turn a limited distance on the rod. A hole at 17 permits the head of the brace-rod to pass through, and a slot at l7 allows the tube to turn so as to form an abutment for the head of the rod, as shown in Fig. 4:. To make this action of the tube automatic, a coil spring 18 connects therewith by a stud 19, and its other end engages a stud 20 on the tie-bar 11.

To collapse the table from the position shown in Fig. 1, the operatorturns the tube 17 against the tension of the spring, until the hole 17 will allow the head of the bracerod to pass out. He then presses backwardly, when the legs fold back, and finally lie flat against the under side of the board. To restore thetablejto its erected position it is only necessary to push the legs iorwardly, any one of the legs being available for that purpose.

Having thus described my invention, I-

claim:

1. In an ironing table, the combination of a board, head and foot legs hinged thereto, diagonal tie-bars conpecting the head with the foot legs, a cross-rod revolubly connecting the tie-bars, brace-rods hinged at one end to the board and mounted slidably in connection with the cross-rod, and a perfo rated tube turnable on the cross-rod, to lock the brace-rods when fully retracted.

2. A locking brace for ironing-tables, com- In testimony whereof I aflix my signature in presence of two Witnesses.
