IRONING-TABLE.

Specification of Letters Patent.

Patented Feb. 15, 1921.

Application filed May 21, 1920. Serial No. 383,098.

To all whom it may concern:

Be it known that I, ARTHUR J. CRANDALL, a citizen of the United States, residing at Olean, in the county of Cattaraugus, State of New York, have invented certain new and useful Improvements in Ironin Tables; and I do hereby declare the followlng to be a full, clear, and exact description of the invention, such as will enable others Skilled in the art to which it appertains to make and use the same.

The present invention is a table mounted on a collapsible support, and by preference the top of the table is an ironing board so that when the structure is set up ironing can be done on it, whereas it occupies but little space when folded and it can be stored in a pantry or closet. The prevalent objection to many structures of this kind which have been devised is that at least one pair of legs is not pivoted directly to the table top or board, and the result in use is a little lost motion of parts, attended by more or less squeaking. In another type where the legs are pivoted to the top or board looseness and rattle or squeaking between and at the crossing point of the legs prevails. These and other objections it is the purpose of the present invention to avoid as far as possible, and this object is carried out by applying a brace for holding the legs distended and the structure set up, which brace is itself a toggle having a knuckle hinge and a finger for holding its links alined; and in addition I use a spring which assists in maintaining alinement and at the same time prevents rattle. Provision is made for the close folding of the two pairs of legs against the bottom of the board, one within the other, so that the collapsed structure occupies but little space.

Details are set forth below and shown in the drawings wherein:

Figure 1 is a side elevation of this ironing table set up ready for use.

Fi 2 is a central. longitudinal section showing the structure in the act of being folded or collapsed.

Fig. 3 is a bottom plan view of the structure completely folded.

Fig. l is a detail perspective view showing a portion of the toggle brace and connected parts.

Referring to the drawings, the numeral 1 designates the top of this structure which in the present instance is an ironing board of proper size and having a padding and cover not illustrated, and 2 are cars depend ing' from the edges of this board near its heel. Mountedvon individual pivots 3 in saidears are the upper ends of an outer pair of legs 4, their lower portions being connected across their lower edgesby braces 5. The numeral 6 designates a block having a notch 7 in its body, and 8 are trunnions at the ends of the block which are pivoted through the legs 4 at about their midlength as shown. I

Secured beneath the board at about the point'indicated is a block 12 whose extremities have trunnions constituting pivots 13 for an inner pair of legs 14 whose lower portions are connected on their lower edges by braces 15, and the bodies of these legs are slotted as at 18 for the reception of the trunnions 8, the slots being of such length that when the trunnions stand in their upper ends the structure is folded as seen in Fig. 3, and the inner legs lie close alongside of and within the outer legs and all legs against the lower face of the board 1, and at this time the braces 5 and 15 are at the bottom of the structure as seen. I speak of these elements as braces, because they are preferably crossed as shown so as to give considerable strength to the structure when set up, but it is obvious that the braces 15 might be replaced by rungs directly connecting the legs 14, whereas the braces 5 must connect the lower edges of the legs 4 because these braces overlap the legs 14 in the folded condition of parts.

A toggle brace connects the block with the board. It is made up of a lower link 20 fastened upon the block 6, an upper link 21 hinged at its upper end at 22 to the bottom of the board 1, and a hinge 23 connecting the meeting ends'of these links on their under side so that in effect a knuckle hinge is produced because the links can open no farther than into strict alinement with each other as seen in Fig. 1. In addition, I attach a finger 24: at its lower end at 25 to the lower link 20, and allow its upper end to overlie the upper link 21, and this finger greatly strengthens and reinforces the knuckle hinge, or may alone be used to limit the hinging movement in one direction. Attached at 26 to the upper link is a spring 27 which leads between the inner legs and is attached at the point 28 to the bottom of the board 1 near the toe of the latter, and the tension of this spring when the structure is set up is exerted to hold the toggle-like brace open and with its links in-strict alinement. At this time the brace holds the trunnions 8 in the lower ends of the slots 18, and the proportion of partsshould be such that the support for the board 1 is now very rigid so that ironing can be done without vibration and rattle or squeaking of parts.

After the structure has. served its'purpose, the user has but to reverse it, collapse the brace as indicated in Fig. 2, and fold the legs as shown in Fig. 3, and the distended spring then lies Within the, notch 7 through the block 6 and also through" a notch 19 with which the block 12 may be provided. The parts are of appropriate materials and sizes! What isclaimed is; a The herein described ironing table com prising a board, a pair of outer legs pivoted at then upper ends beneath one end of the board, a pair of inner legs pivoted-at their upper ends beneath the board near its other end and having slots in their bodies, a block having a transverse notch across its midlength and trunnions at its ends projecting through said slots in the inner legs and pivotedin the outer legs, a toggle-like brace whose lower link is secured on the block and Whose upper link is hinged beneath the board, a finger secured to the lower link and crossing the hinge line. and overlying the upper link when the toggle is open,"said trunnions at this time lying in the lower ends of said slots, and a contractile spring connecting the toggle near its center with the under side of the board, as and for the purpose described.

In testimony whereof, I afiixmy signa ture, in the presence of two Witnesses.
