Feb. 15, 1966 E. E. FOSTER IRONING APPARATUS Filed July 27, 1964 5; 4f 48 O 4Z 38 INVENTOR. EDWIN E. FOSTER United States Patent O 3,234,672 IRONING APPARATUS Edwin E. Foster, Austin, Tex., assignor to Majik-Ironers, Inc., Austin, Tex., a corporation of Texas Filed .Iuly 27, 1964, Ser. No. 385,439 11 Claims. (Cl. 38-30) This invention relates to ironing apparatus, and more particularly to an iron lifting mechanism and to the cornbination therewith of an ironing board.

It is one of the objects of the invention to provide a light weight compact iron lifting mechanism in combination with a folding ironing table or board, which can be stored as a complete unit requiring no more space than a standard ironing board and separate iron.

Another object is to provide ironing apparatus defining. a complete ironing unit which is easy to fold and store, and which can easily be set up for an ironing operation.

Still another `object is to provide ironing apparatus in which iron lifting mechanism is energized by water under pressure. The same water under pressure can supply water for a steam ironing operation and also for a spraying operation.

According to a feature of the invention, the water reservoir normally employed in steam or steam and spray irons is removed from the iron itself, and the space normally occupied thereby is filled with heat insulating material to insulate the iron handle more effectively. Also by removing the water reservoir from the iron, the weight of the iron is constant and does not change as water is used.

According to another feature of the invention, a water reservoir of substantial size larger than the reservoir provided in conventional steam irons may be located on the ironing table, preferably beneath the rear end of the ironing table on the corner nearest the operator to assist in achieving proper weight distribution. Preferably, water from the reservoir is supplied to the iron under pressure by a continuously running electric motor which may be mounted in or adjacent to the reservoir.

Alternatively, the iron lifting mechanism and the water supply for steam or spray operations may be provided by water under pressure from a conventional tap. With this type of construction the iron and the `supporting and lifting mechanism may be removeable from the ironing board for separate storage.

The above and other objects and features of the invention will be more readily apparent from the following description when read in connection with the accompanying drawing, in which FIGURE l is a perspective view of ironing apparatus embodying the invention in erected condition.

FIGURES 2 and 3 are respectively side and face views of the ironing apparatus in stored condition.

FIGURE 4 is an enlarged view of the iron and lifting mechanism with parts broken away and in section.

FIGURE 5 is a partial sectional view of the iron supporting linkage mounting socket.

FIGURE 6 is an enlarged view of the ir-on control valve and FIGURE 7 is a section through the valve of FIGURE 6.

The complete apparatus as illustrated in FIGURES 1, 2 and 3 comprises an ironing board 10 which may be of any conventional construction, and which is adapted to be supported on cross legs 11. Legs 11 carry transverse foot members 12 at their lower ends to support the board in a stable manner on a oor or similar surface. The legs are preferably pivotally connected to the board so that they can be moved from the erected position shown in FIGURE l to a folded position closely adjacent to the under surface of the board for storage as shown in FIG- URES 2 and 3.

ICC

The board has secured to the rear end thereof an elongated supporting bracket or rod 13 which extends parallel to and spaced from one side of the board to terminate in a socket 14 centrally of the length of the board. As best seen in FIGURE 5, the socket 14 is connected to the bracket 13 through a rotatable joint formed by a stub shaft 15 `secured to the socket and extending rotatably into the bracket 13 which may be tubular. Preferably a latch indicated generally at 16 is provided to hold the shaft 15 in an operating position as shown in FIGURE 5 or in a storage position at 90 to the operating position.

The socket 14 supports an iron supporting linkage cornprising a main arm 17 and a forearm 18 pivotally connected thereto on a horizontal axis. This linkage is constructed as more particularly disclosed and claimed in my `Patent No. 2,648,146 so that the free end of the forearm will -be constrained to move in a plane parallel to the surface of the ironing board 10 when the apparatus is in its operating condition. The base arm 17 as seen in FIGURE 5 is pivoted to the upper end of a stub shaft 19 which is in turn rotatable in the socket 14. With this construction it will be apparent that the free end of the forearm can be moved to any desired position over any part of the ironing board.

An iron indicated generally at 20 is supported from the free end of the forearm 18 for vertical movement from a raised position spaced above the ironing board to a lowered ironing position and which it rests on material on the ironing board. As shown, the iron is formed at its forward end with an upwardly extending tubular bracket 21 to the upper end of which a lifting lever 22 is pivoted on a pivot 23. The free end of the lever 22 carries a yball 24 which ts slidably and rotatably in a lspherical socket at the free end of the forearm, so that the iron can be swung to any desired angle relative to the forearm.

The lifting lever 22 is normally urged to a raised position about the pivot 24 in which it will raise the iron above the ironing board, -by a spring 25 which may conveniently be mounted in the tubular bracket 21. To move the lever downwardly about the pivot 24 thereby to lower the iron on the ironing board, a push rod 26 extends through the spring 25 and is pivoted to the lever 22 conveniently -on the same axis as the spring. The lower end of the push rod 26 is connected to an arm 27 pivoted in the iron handle, and which is in turn connected to a second push rod 28 extending through the iron handle, which is tubular, to an operating lever 29. The operating lever 29 is pivoted in the iron handle on a fixed pivot 31 and is pivotally connected intermediate its ends to a pressure responsive device shown as an extensible bellows 32. With this construction when the bellows is subjected to pressure and extended thereby, it will exert a pushing force on the rods 28 and 26 and will swing the arm 22 about the pivot 24 downwardly thereby lowering the iron onto the ironing board and cancelling entirely the effect of the spring 25.

According to the present invention the bellows 32 is adapted to be operated by water under pressure. For this purpose a lwater storage tank 33 is mounted beneath the ironing -board at the rear end thereof. A pump, such as a small gear pump, driven by an electric motor 34 takes water from the tank and forces it out through a supply conduit 35. The supply conduit may extend ythrough the tubular bracket 13 `and may tbe connected through fiexible sections to extensions through the supporting arms 17 and 18 to lead to the iron as shown. A return conduit 36 parallels the supply conduit 35 to return Water from the iron to the tank.

As best seen in FIGURE 4 the supply conduit 35 leads directly to the bellows 32 and leads therefrom through sole plate of the iron t-o supply Water thereto for conversion lto steam, and is provided with Ia seco-nd valve 43 having a manual operating lever 44 extending into the opening of the iron handle so that the supply of water for steam operation can be manually controlled.

The valve 38 as shown in FIGURES 6 and 7 is a double valve having a central xed core portion 45 with a transverse bore therethrough communicating with the conduit 37. A rotatable cap 46 at one end of the valve is formed with an angular lpassage 47 communicating with one end of the ktransverse bore in the core 45 and selectively registerable with passages in Ithe core leading to thereturn lconduit y36 or to the steam supply conduit 39. In one angular position or the cap 46 as shown in FIGURE 7, Ithe passage 47 communicates with the return conduit 36 while in another angular position of the cap, an opposite extension of the passage y47 will communicate with the conduit 39. The cap 46 is turned through an extension arm 48 rigid therewith, and which is connected through a link 49 to a valve actuating -lever S1 pivot'ed to and overlying the iron handle. A spring 52 normally urges the lever 511 upwardly so that the valve 'Will occupy the position shown in FIGURES 6 and' 7, wherein it connects :the conduit 37 to the return conduit 36. When the lever 51 is depressed as by an operator grasping the iron handle, .the cap 46 will be burned counterclockwi-se as seen in FIGURES 4 and 6 to move the passage 47 out of registration with the return conduit 36 and into registration With Ithe conduit 39. Ilf the valve 44 is open at this time, Water will ow from the valve through the .conduit 39 into the sole plate of the iron to be converted into steam for steam ironing in the usual manner.

' The valve is completed by a `second cap 51 rotatably mounted on the opposite end of the valve core 45 and which is'provided with a pass-age 52 communicating with the opposite endl of the transverse bore in .the valve core. The cap 5:1 is adapted to be turned by a lever extension 53 which projects upwardly through the iron handle and terminates at the forward end of the iron handle in convenient position to be moved forwardly by the thumb of the user. -A spring 54 normally holds the lever 53 in ythe position .shown wherein the passage v52 is out of registration with the conduit 41. When the lever 5-3 is pressed forward it will .turn .the cap 5l1 [to a position bringing the passage 52 into registration With the conduit 41 so that water will be supplied to the spray nozzle 42.

For use, the iron apparatus is set up as shown in FIG- URE l With legs 11 extended and with the socket 14 turned to a vertical position at right `angles to the ironing board to support the iron above vthe board. With water under pressure being supplied -to the conduit 35 and with the valve 38 in the position shown, the water will simply ow through the valve to the return conduit 36 without developing any appreciable pressure in :the bellows 3.2. When the lever 51 is depressed to close the return conduit 36 pressure will build up in the bellows and expand it thereby rocking the supporting :lever `22 downwardly about the pivot 24 and lowering the iron onto the ironing board. It will be noted that at this time the full Weight of the iron rests on the material on the ironing board so that ironing can be accomplished effectively. Also at this time a stearn ironing operation can be eifected by moving the control lever 44 to open the valve 43, and if desired the spray may be applied simply by pressing on the upper end of the lever 53.

At the completion of an ironing operation the latch 16 is released and the socket 14 is turned to a position parallel to the underside of the ironing board. The legs lll may then be folded against the underside of the ironing board and the supporting linkage 17 and 18 may be moved to the position indicated generally in FIGURES 2 and 3. At this time the board, the iron and lthe supporting mechanisrn are all arranged in a compact grouping whose. width is approximately equal to or only slightly greater than the thickness of a conventional ironing board in its stored condition. The entire apparatus may `therefore be stored in substantially the same space required ,for 'storing an ironing Iboard alone.

Alternatively, and preferably in the event the pump and tank are replaced by a connection `to a conventional IWater spigot, the iron supporting linkage and iron may be removed from the board by slipping `the shaft y19 from the socket `14, and by providing detachable couplings adjacent to lthe sockets inthe conduits 35 and 36. When this 1s done the board can be stored separately lfrom the iron supporting linkage and the iron, according to the preference of the user.
