Patented May 175, 1934 UNITED STATES PATENT OFFICE 13 Claims.

The present invention is generally concerned with ironing and more particularly relates to a functionally and structurally improved iron having an adjustable handle which may be locked in In certain aspects the invention includes improvements although not exclusively upon the construction for pressing and ironing disclosed in my application Serial No. 526,614, filed March 31, 1931 in which the handle of the iron may be swung from one position to another by first operating a set screw device cooperatively associated with a handle connecting member and its electrode receiving boss disposed therein. In other certain'aspects, although the invention is not limited to being merely an improvement upon the ironing and pressing embodiment disclosed in said application, an object thereof resides in the provision of an ironing device having a handle which may be quickly released from a set position and swung to an-l other predetermined position for automatic locking thereof.

A4 further object comprehends the provision of I a trigger arrangement having a manipulating portion disposed within close proximity to the body of the handle, which portion may be conveniently operated to permit the handle to be quickly swung towards another predetermined position for self locking. l A

A further object of the invention is to provide .a device of the character referred to comprising a heating element disposed in a pressing arrangement formed of upper and lower complementary plate sections one of which includes a pair of terminals or electrodes electrically associated with the heating element, which terminals are properly insulated from and extend through an elevated portion or boss disposed on the upper section, the boss being provided with a curved passageway or groove to guide an interlocking part of a trigger member as the handle is swung and including cut away portions or openings for receiving the interlocking part to prevent a connecting member to which the handleis rigidly mounted and to which the trigger is pivotally sustained from turning.

Other objects and in part obvious are in part pointed out hereinafter.

The present invention will be best 'understood from the following discussion of several typical structural embodiments, reference being had to the accompanying drawing in which:

, Fig. 1 is a perspective view of the electric iron illustrating two set and locked positions of the handle, one position being indicated in full lines and the other in dash and dot lines.

Fig. 2 is a fragmentary elevational view of the iron showing parts thereof in section.

Fig. 3 is a section taken along the line A-A 65 of Fig. 2. y

Fig. 4 shows one manner of mounting the iron on a stand.

Fig. 5 shows the iron mounted on the top plate of the stand.

Fig. 6 shows the iron mounted between the upper and lower plates of the stand.

Fig. '1 is a fragmentary sectional view showing a modication of the locking mechanism and Fig. 8 is a fragmentary view of the handle illustrating the manipulating portion of the trigger disposed in a recess thereof.

Referring to the drawing, the iron is generally designated 10 and comprises upper and rlower

complementary plates

11 and 12 forming a pocket within which is appropriately conned an electric coil or heating element 13. The lower plate is provided on its bottom side 14 with a smooth and flat surface, which surface may be conveniently utilized for pressing and/or other uses requiring a heated surface. The upper and lower plates may be suitably connected together bi fastening members, such as screws 15 or the li e.

The

ends

16 and 17 of the heating element are connected to the free terminals or

posts

18 and 19 which are properly insulated from each other and from the metal upstanding cylindrical boss or elevation 20 extending from the upper plate 11.

The boss 20 includes a recess 21 through which the electrodes extend, the gage of the recess being such as to properly receive a plug (not shown) having the usual sockets for electrical contact with the upstanding electrodes to render the heating coil effective when the plug is connected to a suitable source of electrical energy.

A circular groove or passageway 22 is provided on the lower portion of the boss. This groove guides a cylindrical projection or flnger 23 of a trigger device of a locking mechanism generally denoted 24.

The trigger device includes a lever 25 which has an intermediate portion pivotally connected at 26 to lugs 27 projecting outwardly from and carried by the depending cylindrical hollow housing or connecting sleeve broadly denoted 28.

Suitably disposed in a recess at one end of the lever is a helicoidal spring 29. This spring also has one end thereof bearing against a portion of the outer face of the housing and thus normally urges the upper portion of the lever away from and yits lower portion towards the housing.

'Associated with the upper part of the lever is a free manipulating portion 29. In the form according to Figs. 1, 2, 4, 5 and 6, the manipulating portion is clear of the handle 30 from which the housing or skirt 28 depends and to which it is rigidly fastened. With the embodiment disclosed in Fig. 8, the manipulating portion is arranged with the recess 3l of the handle to preclude any possibility of accidental displacement thereof during the operation of pressing. However, with the form according to Fig. 8, although the manipulating portion of the trigger is inaccessible for accidental operation, accessl thereto nevertheless may be conveniently had for operating the locking mechanism.

The sleeve or connecting member 28 is a hollow cylindrical member and loosely encompasses or surrounds the cylindrical boss 20. Face or side 32 of the housing is relatively shorter than its sides 33. Rigidly attached to the upper portion of the larger face 33 is the handle 30. Therefore if .the handle 30 is swung or shifted the housing turns bodily therewith. Handle 30 embodies a longitudinal and axially disposed channel 34 which registers with opening 35 in the upper portion of the side 33. If desired lan electrical cord may be passed through the hollow handle for electrical engagement with the

terminal posts

18 and 19.

Side 33 of the housing also includes an opening 36 and the boss 20 is provided with diametrically opposed recesses or

openings

37 and 38. Normally spring 29 urges nger 23 of the locking mechanism into the opening 36 of the housing. In the locked position of the handle, finger 23 extends into one of the

recesses

37 or 38 of the boss and thus overlaps a portion of the sides thereof, which sides prevent relative rotation of the housing with respect to the boss.

When locked the handle may be in either of the positions illustrated in Fig. 1. .In the full vline position, the free portion of the handle has been swung as to extend above the upper plate of the iron. Where it is desired to shift the handleto its dot and dash line position to extend laterally of the iron, the manipulating portion 29 is lifted upwardly against the action of spring 29. This causes the cylindrical projection or finger 23 to clear and be free of the sides of the recess 38. Consequently, the handle may be swung in an arc. This also causes the housing to rotate or swivel relative to or about the boss. During thistime, however, finger 23 is guided in the curved channel 22 until the other recess 37 is met at which time, flnger 23 automatically, by

reasonof the action of the spring 29',snaps into position or l interlocks with the sides of recess 37. In other words all that is required to adjust the handle from one position to another involves the operation of lifting the trigger member and subsequently turning the handle until the trigger snaps into position with one of the interlocking recesses of the boss. f

In the form shown in Fig. 4, the free portion of the handle has been swung and locked in a position as to extend to one side of the iron, which portion is appropriately disposed in a stand generally denoted 40 and of the type disclosed in United States Patent 1,708,957 as to present the bottom face 14 of the iron towards the operator for pressing delicate fabrics or the like.

In Fig. 5, the iron in accordance with the invention, is shown mounted on the top plate of the stand.` In Fig. 6 the iron is mounted between the upper and lower plate of the stand.

With the embodiment disclosed in Fig. 2, the interlocking finger part of the trigger locking mechanism is in the form ofl a cylindrical post which cooperates with a cylindrical recess to-prevent relative rotation of the housing with respect to the boss or the complementary upper and

lower plates

11 and 12 which form the presser means. The invention it should be understood is not merely limited to this form of construction for a similar purpose. For example, the trigger kmay be provided, instead of a cylindrical post, with a tapered rib as 50 which cooperates with recess having tapered sides 51 associated with the boss 20.

Since many changes may be made in the above methods of operation and many apparently widely' different embodiments of the invention could be devised without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawing should be interpreted as illustrative and not in a limiting sense.
