ELECTRIC :mou AND STAND Filed Sept. 5, 1933 Patented Feb. 26, 1935 PATENT OFFICE 1,992,624 I ELECTRIC IRoN A'ND STAND Rudolph Kovac, Chicago', Ill., assignor to American Automatic Devices Co., Chicago, Ill., a corporation of Illinois Application September 5, 1933, Serial No. 688,095l 8 Claims. (Cl. 219-25) My invention relates to electric irons and stands and has for its object the provision of a new and improved form and arrangement of l parts by which an electric current may be fed to the iron by a cord attached directly to the iron or alternatively by a cord attached to the stand upon which the iron rests from time to time in the course of ironing operations. It is one of the objects of my invention to provide improved current feeding means on the iron comprising tWo sets of contact members projecting outwardly from the iron in different directions, one set in substantially vertical position for engagement with the plug of the cord when the cord is attached directly to the iron and the other set in approximately horizontal position for engagement with the contact members of the stand when the cord is attached thereto rather than to the iron. It is one of the objects of my invention to provide an improved arrangement of shielding means adapted in one position to shield both of said sets of contact members by cooperation with the plug of the cord when attached directly to the iron and adapted in another position to shield both of said sets of contact members by cooperation with the current feeding means on the stand when the iron is being used with the cord attached to the stand.

It is another object of my invention to improve devices of this type in sundry details hereinafter pointed out. vThe preferred means by which I have accomplished my several objects a're illustrated in the drawing and are hereinafter specically described. That which I believe to be new and desire tocover set forth in the claims.

Fig. 1 is a side view of my improved iron and stand with the cord attached to the stand'for 40 heatingthe irony' g Fig. 2 is al view sinilar to Fig. 1, but partly broken away, and showing the iron in a slightly `diiferent position on the stand so as to prevent delivery ofele'ctric current to the iron;

3 is a view similar to Fig. 2, but showing the cord attached directly to the iron 'rather than to the stand; i

Fig. 4 is a view of the rear end portion of the viron as seen Afrom one side, with certain of the parts broken'away; and

Fig. 5 is across sectional view taken at line 5-5 of Fig. 4'upon aslightly enlarged scale.

Referring-now to the several gures of the drawing, in which corresponding parts are indi 5 cated by the same reference characters,.10 indiby Letters Patent is` cates the body of a stand supported at its rear end by short legs 11 and at its front end by'one or more longer legs 12 so as to stand normally in slightly inclined position. At the rear end of the stand, a bracket 13 projects upwardly carrying at its upper end current feeding means 14 comprising upper and lower insulation members 15 and 16 respectively held in position upon the bracket by means of a bolt 17 (see Fig. 3) and supporting in position two contact members 18 provided at their rear end portions with contact pins 19 which project beyond the insulation members 15 and 16,-only one of said contact members 18 being shown in the drawing. In the arrangement shown a shield device 20 in the form of a flattened sleeve is secured in position about the contact pins 19, being held in position by means of a plate 21 formed therewith and extending between the bracket 13 and the insulation member 16. The arrangement is such that a standard plug 22 of a cord'23 is adapted to t upon the contact pins 19v for feeding electric current thereto, -as is shown in Figs. 1 and 2. 'I'he contact members 18 are preferably of the type illustrated in the copending application of Narodick, Serial No. 554,745, such contact members forming in and of themselves no part of my invention.

In Figs. 1, 2 and 3, I have shown an electric iron 24`of any approved type in position upon the stand 10 in a variety of different relations thereto. Such iron 24 is provided withva handle 25 of wood or other suitable material supported in position between the upper ends of the arms 26 of a yoke secured in position upon the iron by means of bolts 26a. In the arrangement shown the rearmost arm 26 is provided with a housing member 27 upon its rear face, 'such housing in the arrangement shown being formed of sheet metal comprising a front wall portion 28 and side wall portions 29 and 30 formed integrally with the front wall portion 28. In the arrangement shown the housing is secured in position by means of bolts 31 having screw threaded relation to thevarm 26. The arrangement is such that the housing is effectively closed at its front face and at both side faces.

As is clearly shown in Figs. 4 and 5 the iron 24 is' provided at its rear end portion between the side walls 29 and 30 of the housing with contact' pins 32 and 33 which are of standard size and relationship for receiving thereon the plug 22.of

the cord 23 which has been already referred to as having effective engagement with the pins 19. The pins 32 and 33 are mounted in substantially iii) vertical position on the iron so as normally to port the cord a3 Well above the base or the en the plug is positioned upon such pins illustrated in Fig. 3.

the arrangement shown in Fig. `l, the pins 33 extend upwardly through an insula-l her 34 of Wood or other suitable inate-u ii i extends upwardly through an opening in he Wall ci the housing comprising the body of the iron, as is usual in such constructions. lNuts and 3@ upon said serve to clamp auxiliary contact p is 37 and 33 in position upon the pins and espectively, such contact pins 3l and 33 being arranged in substantially horizontal position at right angles to the position' of the s 33 33 so as to extend rearwardly in subparallel relation to the side walls 22 l or the housing 27.

For completing the enclosure about the contact pins carried by the iron to the extent necessary for effective results in my improved arrangement, I .have provided a hood member 33 which is pivotally mounted upon the housing 27 by means or rivets lo as hereinafter described. Such hood 39 comprises side Wall portions il and Ll2 each in the Ytorni ot a sector, such side Wall portions being connected at tl* outer ends by a curved Wall portion 43, as is best shown in Fig. d, the rivets l0 having engagement with the side Walls 2Q- and 3l) of the housing md the side 'walls il i2 oi the hood. The pivotal connection by means of the rivets Lill is such 'that the hood 39 is adapt ed to stand normally in any adjusted position with respect to the housing, so as to close the housing at its upper end as shown in Fig. l. or to close the housing at the rear as shown in Fig. 2, the hood being held yieldingly in adjustedposition by friction.

In the normal use of the iron 24, it is placed in position upon the stand l' with the plug 22 of the cord mounted upon the contact pins 19 in the position as shown in Fig. l. The arrangement is such that when the iron 24 is in position upon the stand, with the hood 39 in its uppermost position as shown in said Fig. l, the contact pins 37 and 33 stand in effective engagement with the contact members 13 of the current feeding means la'. ln the arrangement as shown. in Fig. l, cur" rent is being fed to the heating element of the iron at all times when the iron is in position on the stand. When and if for any reason it may be desirable to place the iron upon the stand Without any additional current being fed to the heating element, this can be effected conveniently by rst moving the hood 39 to its lowermost position so as to hold the iron in slightly advanced position upon the stand and to prevent engagement of the contact pins 39 with the contact members 13,-as is illustrated in Fig. 2 of the drawing. Il at any time it is desirable that current be vfed to the heating element at all times during the ironing operation, the hood 39 would then be moved ,to its lowermost position as shown in Fig. 3 so as to permit the plug 22 to be inserted upon the contact pins 32 and 33 of the iron in lieu of being mounted upon the `pins 19 of the stand.

From the above description, it will be seen that by the use of my improved arrangement the contact pins 32 and 33 and the horizontal Contact pins 37 and 38 are at all times effectively shieldedduring the feeding of current thereto. With Ithe parts in the relation as shown in Fig. 1, the hood 39 prevents access to the contact pins of the iron from above, while the insulation members andA :casacca lil prevent access to auch pins during the time when. the iron is in position as shown in l, and there is, there-fore, no lilreiihood of a person, being shoclred or having the iingers burnt coming into contact with the pins 32 and or the pins 3? and 33. When the hood 39 is in its lowered position as shown in. 3, the housing parte, by cooperation with. the plug 22, effectively shield the contact pins at all times when current is being delivered through the cord and plug,

and shocks and burns to the operator by the iingers coming into contact With either oi pins is also prevented.

Ey my arrangement I have provic d convenient, and el'liective arrangement t be provided readily and cheaply and effective for any one oi the three uses na... contemplated as above described.
