13 Claims.

This invention relates to an electric iron and particularly to an' electric iron of the `folding type.

It is an object of this invention to provide a sturdy though`inexpensivenelectrlc iron which may readily be-folded and when folded occupy a minimum of space. 1

Another object of the invention is to provide an electric iron of whichthe', handle may be moved longitudinally of theiron into a collapsed position in close fitting superposed relation to the base of the iron and to provide means for effectively securing or locking'the handle in its extended position and in the collapsed position whereby to prevent inadvertent collapsing of the handle from its extendedposition and to protect the handle against vibration and fracturing when in collapsed position;

Applicants invention further contemplates the provision yof a relatively very thin iron having simple but effective -means for preventing the heating ofthe relatively thin cover plate by the heating element interposed between this cover plate and the sole`plate. Y

Other and further-objects and advantages of the invention will be apparent from the following description whentakenfinjconnection with the accompanying drawings, wherein:

Fig. 1 represents a perspective View of yan electric iron embodying the invention, the handle being shown in extended position.

Fig. ,2 is a view similar to Fig. 1 but showing the handle in collapsed position. Y

Fig. 3 is an enlarged vertical section taken substantially along the line 3-3 of Fig. 1.

Fig. 4 is a fragmentary view in section through the handle, illustrating the manner in which the' handle may be unlocked for movement to the collapsed position of Fig. 2.

Fig. 45 is a vertical section taken along the line 5--5 of Fig. 1.

Fig. 6 is a vertical section taken along the line 6--6 of Fig. 2.

Fig. 7 is a view in exploded perspective of the elements constituting the base of the iron. Fig. 8 is a fragmentary vertical section taken substantially along the line 8-8 of Fig. 3.

Fig. 9 is a` view in exploded perspective of the handle latching means. i' 50 Fig. 10 is a perspective view of a handle attach? ing element.

' Fig. 1'1 is a view in elevation showing the iron supported in vertical rest position.

Various structures have been devised for col- 55 lapsibly supporting thehandle of an electric ironbut these have not been entirely satisfactory because of their complexity and consequent expense, their bulkiness, even when the handle was collapsed, and their susceptibility to rattlingv and fracturing of the handle and its mounting 5 means when the handle was in collapsed position.

Prior devices of this type, in .which the bulkiness of the iron was reduced' by yreducing the vertical dimensions of the cover plate or shell, were further unsatisfactory because the shell of reduced. size became heated to such a high temperature that after use a relatively long time had to be allowed for cooling of the shell before the handle could be collapsed. 15

An electric iron constructed in accordance with applicants invention avoids these defects' and insufciencies of the prior devices and provides an electric iron of the folding type which, when the handle is in collapsed position, occupies a 20 minimum amount of space; the-danger of vibration and fracturing of the handle is reduced to a minimum and means are provided for maintain.- ing the shell or cover plate at a sufliciently low temperature so that the handle may be moved to collapsed position immediately after use. a

As shown in the drawings, an' electric iron constructed in .accordance with applicants invention embodies a sole plate 2 having a cut out portion forming a channel 4 (Fig. 7) for receiving the heating element 6 which may be of any convenient conventional structure, but preferably comprises the usual resistance coil wound on an insulating plate 8 which is interposed between upper andV lower insulating plates I0 and I2. The heating element 6 is clamped in position in the channel 4 by a relatively thin metal plate I4 also received in the channel 4, the plate I4 being of a shape similar to the sole plate 2 and mounted within the upstanding rim or ange I 6- of the latter. The plate I4 is securedto the sole plate by cap screws I8 (Figs. 3 and 6), passing through openings 2,0 (Fig. 1) in the plate I4 and received in threaded openings 22 in the sole plate. 45

At a rear corner of the plate I4 a portion 24 is cut to form a slot for receiving the usual plug receiving terminals l2li which are insulatingly mounted on a resilient strap 28 and connected to the opposite ends of the resistance coll of the heating element 6. 1

A cover plate or shell 30, preferably of sheet metal, is detachably fastened to the sole plate The cover plate 30 is preferably of a shape similar to that of the sole plate 2 but is longer than the sole plate so as to project rearwardly beyond the heel of the sole plate and is provided with a depending rim oriiange 38 adapted to engage the rim or flange I|6 of the sole plate. In order to permitA circulation of air between the cover plate or shell 30 and the heated clamping and sole plates I4 and 2, respectively, the depending rim or flange 38 is provided'l with a plurality of spaced notches, grooves or openings 40, and it will be evident that, by reason of a circulation of air through the openings 40, overheating of the cover plate or' shell will be prevented.

A terminal housing 42, preferably of sheet metal, is received within an opening 44 in the cover plate or shell 30 and is secured, with the strap 28, to the clamping plate I4 as by a cap screw 46 passing through apertured lugs 48 and 49 ,of the terminal housing and strap '28, respectively, and received within a threaded opening 50 in the clamping plate. The horizontal, outwardly projecting lugs 5| and 52 formed on the housing 42 and the strap 28 are clamped between the cover plate or shell 30 and the clamping plate |4, as shown in Fig. 5.

The depending rim or flange 38 of the cover plate or shell 30 is partially cut away at the rear portion thereof` to permit a rest member 54 to be interposed between the rear portion of the cover plate and the clamping plate |4. The rest` member 54 rests upon the rim i6 of the sole plate and is provided with an upwardly pressed or offset portion 55 forming' an upstanding shoulder or ridge 56 to engage the flange 38 and lock the rest member to the shell to hold the rest member against relative movement. ,This rest member extends rearwardly beyond the rear edge of the cover plate or shell and is provided at its rear edge with spaced projecting lugs 51 which arepreferably bent upwardly to lie so as properly to engage the iiat supporting surface whenthe iron is in vertical position, as shown in Fig. l1.

A forward edge of the rest member is notched as at 58 to snugly receive the rear edge of the terminal housing 42 to oder further support for the housing when the iron is in vertical position and in turn to utilize this housing in supporting the iron in vertical position.. -The rest member is also provided at its forward edges with a struckup boss 59'` engaging the cover plate to support the latter and apertured to receive the rear screw 32 by which the coverv plate is secured to the sole plate so as to provide an additional spaced point of supporting engagement between the rest memf' ber and the sole plate. Openings 60 in the portion of the rest member lying beneath the rearwardly projecting heel portion of the cover plate or shell and the rear edge of the sole plate further facilitate the circulation'of air between the cover plate or shell and the clamping and sole plates and with the air circulating openings 40 in the rim of the cover plate insure the maintenance of the cover plate or shell at a sufficiently low temperature for satisfactory use and to permit folding of the handle into close juxtaposition with the cover plate or shell without the danger of mar-l ring the handle or burning the fingers of the user.

The handle means 62 comprises the usual handle 64l of heat insulating material and front and rear handle supporting members 66 and' 68. The front supporting member 66 preferably comprises a wire or rod of resilient material bent to provide animate ceived'in threaded openings 36 of the s ole plate.

spaced legs 10, integrally'connecting spaced feet 12, with an upper, horizontally extending handle engaging portion-14, the spaced feet 12 being integrally joined by a lower, horizontally extending pivot portion 16. As shown in Fig. 6, the feet 12 converge from the pivot portion 16 so as snugly to receive the handle when in collapsed position and resiliently latch the handle in that position.

A clip 18, having a substantially semicylindrical body portion (Fig. 7) receiving the pivot portion 16 of the member 66 and depending lugs 82, pivotally secures the supporting member 66 to the upper flat surface of the cover plate or shell 60, the lugs 82 passing through slits 84 and bent over into attaching engagement with the undersurface of the cover plate (Fig. 3).

The handle supporting member 66 is detachably locked to the front end of the handle 64 by the locking or latching means 66. This locking means comprises a plate 88 (Fig. '7) secured to the handle in the end groove 90 (Fig. 3) as by a screw 92. A latching clip 94 (Fig. '1) isl pivotally mounted on a resilient plate or strip 96 secured to the handle by the screw 92 and overlying the plate 68 (Figs. 3 and 4). The clip 94 passes through a slot 96 (Fig. 7) in the spring plate 96, by the edges of which it is pivotally associated with said plate, and between the plate 96 and the will be retained in its non-latching or released position, as shown in Fig. 4.

Theclip 94, exteriorily. of the spring strip 96, is shaped to provide a groove/|02 (Figs. 4 and 7) and a nger or operating portion` |04, the groove |02 receiving the handle engaging portion 14 of the handle supporting member 66. The lowerl edge portion |06 of the spring strip 96 extends over the groove |02 when the clip 94 is in latching position and bears against the portion 14 ofl the member 66 to retain it in the groove 02 (Fig. 3).- It will be evident thatV by engaging the iinger |04 of the latch clip 94 the same will be raised from the position shown in- Flg.'3 to theposltion shown in Fig. 4, thereby to release the handle supporting member 66 from the handle.

The rear handle supporting member 68 preferably comprises a wire or rod bent to provide spaced feet |08 (Figs. 1 and 2) integrally connected at their lower ends by a horizontally extending pivot portion H0 and integrally connected to a horizontally extending attaching portion |I2 by spaced legs ||4 (Figs. 1 to 4). A clip ||6 similar `in all respects to the clip 18 pivotally fastens the member 68 to the fiat upper surface of the cover plate or shell 80. The member 68 is pivotally fastened to the handle -64 by a plate ||6 secured to the handle as by a screw ||8 and having a struck out portion |20 forming an inwardly facing groove for pivotally receiving the horizontally extending portion ||2 of the member 68.

At its lower edge the plate ||6 isprovided with laterally extending lugs |22 adapted to engage the legs |08 of the supporting member 68 at points spaced sufliciently from the center of the portion ||2 when the handle is in extended posi- Ation so as to limit the movement of the handle handle supporting member B6 may be pivoted in a counterclockwise direction from the full line position of Fig. 3 to the dotted line position of said figure, or the full line position of Figs. 2 and 6, in which position the horizontally extending portion 12 of this member 66 rests upon the upper surface of the cover plate or shell 30 and thereupon the handle 64 may be moved in a forward direction longitudinally of the iron to a collapsed4 position in close fitting relation to the base of the iron, as shown by the full lines of Figs. 2 and 6 and the dotted lines of Fig. 3.

In moving to this position the handle 64 will be forced between the spaced resilient legs 1I! and feet 12 of the front supporting member 66, as shown in Fig. 6, and resiliently held by this vmember against vibration when in collapsed position and resiliently latched in this collapsed position. The position which the handle occupies in relation to the base when collapsed and the latching of the handle in this position proy tect the handle against the dangers of fracturing during transportation or storage;

It should be notedthat the feet 'l2 and |08 of the front and rear handle supporting members 66 and 68, respectively, extend in opposite directions along the cover plate when the handle is in extended, operating position as shown in Figs. land 3 and therefore absolutely prevent move- ,ment of the handle relative to the base so long as the front supporting member is latched to the handle.

It will be seen from the foregoing description that applicant has provided a sturdy and inexpensive, relatively very thin, collapsible iron wherein means are provided for preventing overheating of the cover plate; wherein the handle from the foregoing description and it is obvious l that numerous changes may be made in the form, construction and arrangement of the several parts without departing from the spirit or scope of the invention, or sacrificing any of its attendant advantages, the -form herein'described being a' preferred embodiment for the purpose of illustrating the invention.
