Any type of ironer construction may be used. By way of illustration the ironer disclosed in my copending application S. N. 209,227, now Patent No. 2,379,788, patented July 3, 1945, is shown. The mechanism is mounted on a folding work table which becomes a cabinet enclosing the ironer when folded.

The ironer as shown in Fig. 1 is fastened to the top of the work table I. Additional working surface is provided by a front helf extension 2 hinged to the work table I by hinges 2a. In a similar manner the working surface is extended to the rear by the rear shelf 3 also hinged to the table i. A side extension 4 is also provided and is hinged to the tablel by hinges 40:. These hinges may be of the double fulcrum variety shown in Figs. 11 and '12. For example, the leaf may be secured to the extension 4 and may be fulcrumed at H to the movable leaf 12. The leaf 12 may be fulcrumed at '13 to the leaf M which is secured to the table top I The movable fulcrum H swings from the position shown in Fig. 11 to that shown in Fig. 12, the operator exerting a slight lifting movement to the extension 4. To prevent articles from falling off the rear of the work table a vertical barrier 5: extends upward from the rear edge of the shelf 3 and preferably is fixedly secured to the shelf 3 at right angles thereto. The table I is supported on legs 6 and 'l which carries a pedal base 8, having control pedals 9 and H. The leg 6 and l are hinged to the table I, and the pedal base is hinged to the lower end of leg 1. The pedal base 8 is provided with hooks 8a which fit into slots 6a in legs 5. This cabinet may be folded into a compact case which rests on the base I fixed to the lower end of leg 1.

Fig. 2 shows the cabinet partially folded. The three shelf extensions 2, 3 and 4 are folded-up and become two sides and an end of the protecting cabinet. The vertical barrier 5, attached to the rear shelf extension, becomes the upper or third side of the cabinet. The original work table top I forms the under or fourth side of the cab- Suitable frictional catches may be pro-- inet. vided to hold these sides in folded position. For

example, the barrier 5 may be provided with a metal or leather strap 58 (Fig. 13) which is pro: vided with a recess 5I, which receives the button pedal base 8 is folded on its hinges against the right vertical leg 1, as indicated by the dotted lines and the small permanent base ID of the machine is now revealed. A small latch (to be described in detail later) holds the pedal base 8 indie folded position.

Fig. 4 shows the cabinet more fully folded, the

' left leg 6 of the ironer being folded up under the ,table top I.

A small latch (to be described in more detail later) holds the left leg in the folded position. r

The ironer cabinet is now folded down against the right leg 1 as shown in Fig. 5.

The resulting unit, as shown in Fig. 6, is a neat cabinet enclosure for the ironer that occupies very little fiOOr space and is so small that it can be readily stored in any portion of a kitchen or laundry. A pair of small wheels I2 on the cabinet base It are provided to aid in moving the unit.

To unfold the ironer, as shown in Fig. 6, the

.operator grasps a small handle i5 and raises the. left end of the cabinet to a position slightly higher than that shown in Fig. 4. Automatic latches (to be described in more detail later) first release the left leg 6 and subsequently the pedal base 8. The

pedal base 8 engages the left leg 6, the hook 8a entering and resting in the slot 5a. The cabinet is then lowered until the left leg 6 bears on the floor, and the ironer appears as shown in Fig. 2.

The sides are then unfolded, and the ironer appears as shown inFig. 1 and is ready to use. The .pedal base 8 is provided with pedals 9 and II which are connected with cable control I02 and I08 for the ironer.

Details of the automatic latching mechanism are shown in Figs. 1 to 10. The table top I preferably is a sheet metal panel having side flanges 55. The leg 6 preferably is a sheet metal panel having side flanges and an end flange 51 reinforced by an angle iron 58. The leg 1 is a sheet base 8 is a sheet metal panel having side flanges 60. The end of leg 6 is provided with a pair of feet, as illustrated in Fig. 1.

The table top I i hinged to the leg 1 by pins I33 which pass through flanges 55 and 59 of top metal panel having side flanges 59. The pedalcarry pins I39 which support the ends of latches I31.

The latches I31 have hooks I40, with tapered lower edges. The flanges 56 of leg 5 have outwardly directed projections I36 which hook over the hooks I45 and retain the legin raised position until the unfolding operation is started.

The flanges 55 of the top I carry right angled brackets I58 to which are riveted spring latches I34 having hooks I34a. When the pedal base 3 swing upwardly its end, I5I, hooks under hooks I34a, so that the leg 8 is retained in it folded, upper position until the unfolding operation is started.

Further details are as follows: The leg 5 is hinged to the top I by means of a pin I83, which is welded to the flange 55 of the top I and which loosely passes through flange 55.

The leg I has, at its upper corners, a bent leaf I10, which cooperates with the latch I34 to lift the latch I34 when the top I is moved to the position I46, as indicated in Fig. 10. The leg 1 also has openings I15 at its upper corners to receive the flanges 55 of the. table top I.

The pedal base 8 is provided with two flanged openings Ill and I12 in which the pedals 9 and II are hinged by hinges I13. The base 8 also has an end flange I14 and two end ears III through which the hinge pins I I5 loosely extend from the leg 1 and base IS. The pins III) may comprise a bolt having a head I15 over which an extended threaded nut I11 i placed to clamp the leg 1 and base I0 together. The end of the bolt constitutes the pin Iill through which the end ears III are hinged. L

Rods I5! and I05 have bearings in the flanges of openings Ill and I12 and in flange I14. The rod IilI is bent at I83, with the end I030. attached to the rod or cable I08. The other end of .rod MI is bent at I91, and again at I18, where it is provided with a pulley I19 to cooperate'with the bottom of pedal 9. Whenever the pedal the depressed, it, depresses pulley I19 and swings rod IflI clockwise, thus lowering the end I03a which is connected to the cable or rod I08.

The rod IE5 is bent at I04, the end ma being connected with the cable or rod I02. "The other end of the rod IE5 is bent at I and again at I3I, where it is provided with a pulley I32 to cooperate with the pedal I I. Whenever thefpedal II is depressed, the pulley I82 is depressed and the rod I55 is turned clockwise, thus lowering end I 64a together with cable or rod I82.

When the pedal base 8 is swung upward, on the pins H5, the pedals 9 and I I, together with the bent portions I03 and I54, fold inwardly, thus allowing the face of pedal base 8 to come into proximity of the face of leg I.

The base It includes a bottom pan I98 having flanges IQl and I92, and a vertical pan I93 having flanges I94 and I95.

During the unfolding operation the left leg 6 is automatically released by lifting the left end of the cabinet to a position indicated by the'line M4 in Fig. '1. Levers I 32 pivoted onpins I33 engage an extension MB of the right leg I. Levers I42 also engage latches I31. The lifting of the left end of thecabinet inclines the table top I of the cabinet inclines the table top I to the'rposition shown by the dotted line M6, in Fig. 10.

which automatically unhooks the spring latches l34,by lifting them above the edge of pedal base, 8 and releases the pedal base 8 so that it can "swim-2g down, as indicated by the dotted lines in "Fig.- a

a In operation, the machine assembly, as shown in Fig. 6, is moved to so that it can swing down as indicated by the dotted lines in Fig. 4-. Similarly, lifting on the handle is a position indicated a little further to swing the cabinet to ing the latche I34 from the edge of the base 8 and allowing the base 8 to swing down, as indicated by the dotted lines in Fig. 3. The shelves 2 and 4 and the back and cover 3 and 5 are then unfolded to the position shown in Fig. l, for operation of the ironer.

When the ironing operation is finished, the op"- erator then folds the cabinet by folding upwardly the sides and ends 2, 3, 2 and 5 to the position shown in Fig. 2. Thereafter he folds the base 3 upwardly as indicated by the dotted lines in Fig. 3, after which he fold the leg 6 upwardly as indicated by the dotted lines in Fig. 4. Thereafter he lowers the main body of the cabinet downwardly, as indicated by the dotted lines in Fig. 5, so that the cabinet is now in vertical position, as indicated in Fig. 6. The cabinet may then be rolled, on rollers I 2, by a slight tilting movement, to its place of storage.
