ELECTRIC IRON Filed Feb. 7, 1940 2 Sheets-Sheet -2 PatentedY Mar. 18, 1941 UNITED STATES PATENT OFFICE ELEc'rRic IRON Application February 7, 1940, Serial No. 317,644

12 Claims.

This invention relates to an electric iron.

It is an object of this invention to simplify the construction, decrease the heating of the handle, and improve the operation of an electric iron;

and particularly, a thermostatically controlled temperature adjustable electric iron.l`

A further object of applicants invention is to provide an iron with a one piece streamlined shell construction in combination with extremely lo simple means for supporting the temperature adjustment means, the terminal means, and in addition providing an intermediate support for the shell, cooperating with the shell 'to form a housing chamber for the working parts of the iron. Applicants invention .also contemplates the provision of simple, inexpensively produced and assembled means or supporting the handle in spaced relation to the shell so that air may circulate in the space between the handle and the shell to dissipate the heat of the shell, and main- '20 tain the handle in a relatively cooler condition.

Another object of the invention is to provide in an iron a streamlined handle mounted on a streamlined shell and provided with a cavity housing the Iterminals of the iron andrhaving 25 an integral at and then outwardly turned surface portion forming a rest for .the fleshy part of the hand of the user, and a relatively thin edge for supporting the iron in vertical position, the

cavity in the handle being closed by a member which locks in place a member cooperating with a portion of the handle to form a supporting bushing for the supply conductor or cord.

A further object of the invention is to provide a thermostatically controlled iron, wherein the thermostatic control-element is mounted in direct heat conducting relation to and upon the sole plate of the iron and always exercises` its control functions at the desired .temperatures of the sole plate, and the .temperature adjustingelement is supported independently of the temperature controlled and adjustable contacts, so that the adjustment of the element will not aiect the mounting for the contacts, and the contacts may f be readily and independently replaced when worn.

Other and further objects and advantages of the invention will be apparent from the description when takenin connection with the accompanying drawings, wherein:

As shown in the drawings, an electric iron constructed in accordance with applicants invention embodies a sole plate 2 having a reduced upper surface portion 4 from which extends small pieces or lugs 6 adapted to engage the inner surface of the shell 8 at the lower edge thereof to position the shell on the sole plate in proper position relative thereto and tending to limit or prevent lateral movement of the shell on the sole plate The heating element l0 rests upon the upper surface portion 4 of the sole plate, and may be of any convenient conventional structure, but preferably comprises the usual resistance coil wound on an insulating plate l2 interposed between upper and lower insulating plates i4 and I6, The heating element is clamped in position on the sole plate by a clamping plate I8 of a shape similarto the sole plate and secured to thersole plate by screws 20, 22 and 24 passing 5 through apertured bosses or lugs 25, 28 and 30 formed integrally with the clamping plate and projecting upwardly therefrom.

A bimetallic thermostatic control element 32 is fastened directly to the sole plate in heat con- 50 ducting relation thereto as by a screw 34, the bimetal element passing upwardly through elongated openings 36 and 38 in .the plates of the heating element l0 and in the clamping plate I8, and being bent to engage in overlying relation I6 an insulating button 40 secured to a resilient contact strip 42. Since the thermostatic element is in direct engagement with the sole plate, the heat of the sole plate is directly conducted to the thermostatic element, and the element therefore is constantly maintained at the temperature of the sole plate and follows directly-the variations in temperature of the sole plate. As the temperature of the sole plate increases the radius of curvature of the forward end portion of the thermostatic element decreases so that the free edge of the element deflects the resilient contact strip downwardly to separate the contact lf3 carried thereby from the upper contact Q5 carried by a superimposed resilient contact strip d. As the temperature of the sole plate decreases the free end of the thermostatic element moves upwardly andthe resilience of the contact strip Q22 causes its contact it to reengage the contact fit.

The Contact strips t2 and i8 are carried by a support 50 which comprises a plate or bracket 52 secured to the sole plate as by screws 5d on which is supported a series of insulating blocks or pieces 56 insulatingly supporting the contact strips l2 and 48 on the plate 52 and insulating the strips from each other, the insulating pieces being fastened together as by insulated rivets or pins 58. It will be seen that by virtue of this mounting the contact strips are supported as an independent unit on the sole plate so they may be readily removed independently of the other Working parts of the iron, or for replacement as the contacts or strips become worn.

The contact strip d8 carries at its outer end' an insulating button 5U' which by the resilience of the strip d8 is constantly maintained in contact with an adjusting screw d2 for determining the setting of the contact i6 relative' to the contact M. The adjusting' screw d2 is mounted in an internally threaded bushing ed passing through an opening in the mounting plate t@ and peened over at its upper edge and thus clamped to the mounting plate. The mounting plate 55 in addition to supporting the mounting bushing for the adjusting screw also provides a support for the terminal of the iron and intermediate support for the shell and a sole member cooperating with the shell to enclose the operating or working parts of the iron.

The cover plate'or shell 8, which is preferably of sheet metal, is of streamlined configuration and extends from the toe of the sole plate to a point well beyond the rear or heel of the sole plate. The shell 8 rises from the toe of the sole plate to a point adjacent the rear edge of the forward foot portion of the handle E8 and then gracefully inclines downwardly to the point A (Fig. 2) beyond the heel of the sole plate at v which point the slightly inclined rear portion of the lower 'edge of the shell intersects the upper surface of the shell. From this point the stock of the shell extends upwardly at an angle to the upper' surface of the shell and to the lower edge of the shell to denne a rest portion 7B, the rest portion l@ being concave in transverse configuration to provide spaced feet l2 no thicker than the thickness of the stock from which the shell was formed. The upward turning of the portion 'lil provides at the point A a rounded smooth edge, which will not snag or catch articles being ironed. The upward extension of the rest -member disposes the entire member so-that it will not snag or catch articles being ironed. The shell isp formed with reenforcing ribs or ridges 74 extending longitudinally of the shell and in parallel relation i'rom4 diverging to the rear end of the shell.

the toe to a point adjacent the forward foot of the handle 68 and then flaring outwardly or The upper surface of the shell at an intermediate point, preferably centrally thereof, is depressed as at l@ to form a part circular cavity receiving a shiftable stop linger l@ splined or.

otherwise fastened to the upper end of the adjusting screw 62 which passes through an opening 8! in the bottom of the depressed portion ld. The stop finger i8 is limited in its movement by the vertical edges 82' which constitute edges of the part circular cavity formed by the depressed portion 76. The shell is secured to the mounting plate 56 as by screws 8d received in counter-sunk openings in the depressed portion i6 and threaded into the portion 8S of the mounting plate 65. The depressed portion le and the shftable stop iinger 78 and the screws @l in this depressed portion are covered by the disc-like indicia bearing portion B8 of an adjusting member @t pinned to the upper end oi the adjusting screw 62 as by set screw 92 lying beneath a radially projecting operating nger 94 of the member 90. A resilient washer d6 is interposed between the disc-like portion 88 of the member all and the shiftable stop iinger "i8 so as to maintain this stop finger in surface engagement with the bot'- tom of the depressed portion l5 as the adjusting screw 62 in being adjusted moves vertically. A reference symbol 98 for the indicia bearing dise portion de of the member 90 may be.etched, stamped, or otherwise formed, in or on the shell adjacent the edge of the disc-like portion t8.

The portion d@ of the mounting plate 66, which portion supports the mounting bushing dll for the adjusting screw 62, and the parts carried by this screw, and which also supports the shell 8, is inclined and extends generally parallel to the depressed portion '16 of the shell in close juxtaposition thereto so that the bottom of the depressed portion 76, counter-sunk as at l for the reception of the screws 8d, engages the portion 86 of the mounting plate. Hence the shell is vsupported directly on the mounting plate so that the screws 8d act merely as fastening means, and in being placed will not warp the shell or the mounting plate` to thus, as in prior devices, loosenv the mounting plate from its support or destroy or detrlmentally affect the calibration or setting. of the thermostatic control means.

On opposite ends of the portion 86 the mounting plate is oir-set downwardly to provide portions l02 and llll extending substantially' parallel to the plane of the clamping and sole plates and secured to the clamping plate by being interposed between the head of the mounting screws 20, 22, and 2d and the associated bosses 2S, 2@ and 3@ of the clamping plate. ri'he oi-set portions ltl and |06 of the mounting plate are provided with apertures it@ and los, respectively, for receiving the shanks of the attaching screws.

The iiange lill connecting the portion a@ to the portion Mld of the mounting plate is reinforced by a portion or section H2 pressed upwardly from the portion it and the ange il@ so as to strengthen the support oered for the portion 8er The mounting plate 66 rearwardly of the oi-set portion ldd provides a terminal mounting portion l lf3 of relatively reduced crosssection terminating in an enlarged downwardly extending shell supporting and closure member H6. 'Ihe shellV supporting and closure member, or portion H6 of the mounting plate, is preferably inclined to the plane of the sole plate andv extends substantially at right angles to the wall or wall surfaces of the shell so as to provide an efficient supporting member not liable to deformation as the user applies a downward and forward thrust on the handle in utilizing the iron. The upper and outer edges of the portion ||6 of the mounting plate engage the entire wall or wall surfaces of the shell in the plane of this portion and at its lower edge engages the rear pieces or lugs 6 extending outwardly from the inwardly off-set surface portion 4 of the sole plate so that the forward and downward thrust applied to the shell through the handle will be directly transmitted by the portion I6 to the sole plate. It will be extremely unlikely therefore that the forces applied to the shell or the inertia of the sole plate will cause a deformation or warping of the mounting plate 66 and/or the shell 8.

The terminals lill and |26, which are preferably of relatively thin bar stock, are supported on the portion |i4 of the mounting piateby insulated pins or rivets |22 passing through openings |24 in the portion |54 of the mounting plate, the terminals being insulated from the portion ||4 by suitable strips of insulation. The terminal ||8 is connected to the contact carrying strip 46 as by a conducting strap |26 secured by screw |28 to the terminal H8, the screw |28 passing through an enlarged opening |30 in the portion l|4 of the mounting plate. One end of the resistance member of the heating element |0 is connected to the contact carrying strip 42 as by the terminal |32 and the other end of this resistance member is connected to the terminal |20 as by a strap |34 secured to the terminal by the screw |36, the screw |36 passing through an enlarged opening |36 in the portion i4 of the mounting plate. The terminals or bars ||8 and |20 pass upwardly from the mounting plate at an angle through an opening |40 in the rear portion of the shell, and are received in a cavity in the handle 66. 1

The handle 68 is of a streamlined configuration and preferably formed of a suitable heat-resisting moldablematerial, such as Bakelite or simllar substance. It comprises a forward or front foot portion |42, a backward or rear foot portion |44, and an interconnecting integral hand grip portion |46. At the juncture of the hand grip portion |46 and the rear foot portion |44 the handle is provided with an integral rearwardly projecting portion |46 which is formed with an upper surface portion which merges into the upper surface of the rounded hand grip portion |46, but is substantially fiat throughout its larger pcrtionas at |50, the surface portion |50 merging into a slightly upturned end portion |52 which forms with the rear generally concave surface |54 a relatively thin edge |56 which cooperates with the relatively thin feet 12 of the rest portion 10 in supporting the .iron in vertical position. By reason of the substantially fiat surface portion |50 and the slightly upturned surface portion |52, the rest member |48 provides a very restful support for the fleshy part of the hand of the user as he pushes downwardly and forwardly to move the iron over an article being ironed. .y

In order to maintain the handle in a much cooler condition than the shell, front and rear members or means |58 and |60 are provided which support the handle in spaced relation to the upper surface of the shell and conform in shape to the front fand rear foot portions |42 and |44 of the handle at the bottom thereof, the peripheral walls of these members |66 and |60 conforming to the lines of the handle. The vertical wall or walls of these members are provided with a plurality of spaced openings |62 and |64, respectively, separated or defined by generally triangular pieces or lugs |66 and |66, respectively, providing substantially point-like sources of engagement with the surface of the shell, and therefore automatically aligning the members relative to the surface of the shell and permitting greater tolerances in the manufacture of these irons. The pointing of the lugs |66 and |66 also reduces the conduction of heat from the shell to the members to a minimum. The front member |58 at its forward toe portion is formed with a downwardly extending lug or lugs |10 received in a substantially V-shaped opening |12 in the shell to secure the member more rigidly against forward movement relative.to the shell. The openings |64 in the rear vertical wall of the rear handle supporting member are defined or spaced by generally rectangular pieces or lugs |14 which engage thesurface of the shell along the edge A defined by the rest portion 10 of the shell so that these pieces or lugs are in engagement with this rest portion, thereby preventing rearward movement of this member |66. It will be seen that the lugs or pieces |10 and |14 in preventing movement of the handle supporting and spacing members |56 and |60 relative to the shell also increase the rigidity of the connection of the handle to the shell. The openings |64 in these handle supporting and spacing members permit a relatively large volume of air to circulate between the surface of the shell and the front and rear feet of the handle, so that the handle is maintained in a relatively cooler condition, andv the heat of the shell is more effectively dissipated. Also it should be noted that the handle supporting and spacing members |58 and |60 provide a very convenient and simple way in which to support a moulded handle on a streamlined metal shell, it having been found diilicult lto so precisely form the moulded surfaces of the front and rear feet of such a. handle, and the surface of the shell, that the handle may be mounted on the shell without disiiguring spaces between these surfaces. The members |58 and |60 being of relatively thin sheet metal stock can be easily formed or reshaped in assembling the iron so' that the handle rests snugly upon the upper surface of these members while the lower edges of these members snugly contact and conform to the lines of the shell. The handle is fastened to the shell by a screw |16 received in an internally threaded bushing or sleeve |18 in the front foot portion |42 and by screws |80 countersunk in the upper surface of the shell and threaded in the rear foot portion |44.

The terminals or bars ||8 and |20 pass through enlarged openings |82 and |84 in the rear handle supporting member |60 and the rear foot |44 of the handle and into a cavity |66 in this rear foot portion. A partition |68 formed integrally with the handle projects into the cavity |66 between the terminals ||6 and |20 and provides means insuring maintenance of the terminals in the proper spaced relation. The supply conductor or cord |60 passes into the cavity |86 through a slot or opening |62 formed in a side wall of the rear foot portion |44 and is connected within the cavity to the terminals ||6 and |28. The cord is provided with a tapered rubber bushing |64 formed at its inner end with an anupper end to merge uniformly into the concave rear surface ld of the rest member or portion 'its of the handle. As shown best in Figure 12- g@ the closure member ist is formed with an integral lug or flange 2812 of reduced size extending into the slotfl or opening 92 to close the rear portion of this slot or opening. A member or plate 2M, preferably of insulating material, is

3g fitted into the cavity tt against the slotted side wall of the cavity and is slotted as at 2h35 to embrace therein the end of the bushing |96. The member mit is of a size such that when tted into the cavity E86 and locked in place by the closure g@ memberuiat, it compresses and clamps the bushing against the forward wall of the 'slot 892 and is interposed between the side wall of thecavity we and the annular flange ist of the bushing so as to retain the supply cord against outward gg movement.

1t will be seen from the foregoing description that applicant has provided an electric iron in which the construction is simplified; the heating of the handle is decreased; the operation of an y@ electric iron is improved; the iron embodies a one-piece streamlined shell construction in combination with extremely simple means which supports the temperature adjustment means, the terminal means, and in addition provides an intermediate support for the shell, cooperating with the shell to form a housing chamber for the working parts of the iron; means are provided so that air may circulate in the space between the handle and the shell to dissipate the heat of g@ the shell and maintain the handlein a relatively cooler condition; the iron comprises a streamlined handle mounted on a streamlined shell and provided with a cavity housing the terminal of the iron; the handle of the iron has an integral 'da i'lat and then outwardly turned surface portion forming a. rest for the fleshy part of the hand of the user, and a relatively thin edge for supporting the iron in vertical position; the terminal receiving cavity in the handle is closed ab by a member which locks in the' cavity a member supporting the supply conductor or cord against breakage due to strains upon the cord; the iron embodies a thermostatic control element mounted indirect heat conducting relation to and upon mit the sole plate of the iron and always exercising its control functions at the desired temperatures of the sole plate; and in which the temperature adjusting element is supported independently of the temperature controlled and adjustable con- @o tacts, so that the adjustment of the element will n ot aect the mounting for the contacts, and the contacts may be readily and independently replaced when worn.
