(ci. 21a-25) My invention relates to sadirons and particu larly to electric irons wherein a detachable guard supplied with a plug is ordinarily used for at tachment to terminal posts on the iron. -Among 5 the objects of my invention is the provision of a new and improved sadiron structure comprising only must material costs be reduced to a mini mum but the number of operations necessary to assemble the parts must be made just as few as possible and this can be accomplished in many in ber adapted to serve as a support for the termi nal posts and simultaneously provide a cover stances by reducing the number of separate ln dividual connections which must be made in or der to secure all of the parts together. Another factor which cannot be overlooked during this simplifying process is the inevitable requirement or closure for a portion of the iron casing com monly known as the heel. of safety which is especially necessary in electric 10 appliances of this sort designed for household use. Another object is the provision in an electric sadiron structure of a mounting for the terminal In the invention disclosed, meeting to-a large. extent the rigid requirements above recited, there the formation and adaptation of a metallic mem posts supplied by a single separate metallic part 15 which is clamped in the iron between sole plate and casing and which acts also in the nature of'a columnar reinforcement between the sole plate and the casing. ' Still another object is the provision in an elec 20 tric sadiron of a .combined support for the termi nal posts and cover for the under side of the heel has been provided a structural unit integral in itself, serving a plurality of purposes and re 15 quiring a minimum of operations to install it in an appliance. In the embodiment shown the part in question is composed of a sheet metal stamping formed substantially in the shape of the letter Z as viewed in cross section providing a plate or support at the top leg to which terminal posts ' which is made from a single stamping provided l -may be attached and extending rearward at the with means'for engaging portions of the casing and adapted to be clamped into position against 25 the sole plate of the iron bythe casing wherein it is firmly supported by pressure and friction in such a manner as to provide a solid base for the terminal posts while at the same time acting as a reinforcement for the casing or shell adjacent the 30 point where the terminal posts are attached. With these and other objects in view my in vention _ consists in the construction, arrange-~ ment and combination of the various parts of my device whereby the objects contemplated are at ß' tained as hereinafter more fully set forth and pointed out in my claims and illustrated in the accompanying drawing in which: _ extending rearward to form what is known as a heel or heel rest. _ ' As shown in the drawings an electric iron hav ing a base A is provided with a handle B for manipulating it over an ironing board. A control D is provided for turning the iron on and off. The 'base -ls composed of a sole plate III within which is embedded a heating element i2 and sur mountlng the sole plate is a weight member Il at tached thereto. Above the sole plate and weight is a shell or casing I6 which entirely covers the 35 base portion of the iron and extendsy rearward at Il in the form of a hollow heel or heel rest. The Fig. 1 is a small scale side elevation of an iron withthe device installed therein. 40 _bottom leg to close a cavity formed at the rear of the iron by the application of a shell or casing ' Fig. 2 is a fragmentary longitudinal elevation partly in section showing the rear portion of an iron with the device installed. _casing is 'secured to the sole plate structure by means of screws 20 threadably engaged in the weight Il. The handle B is attached to the base 40 by means of a bracket 22 at the front and an other bracket 24 at the rear 'and these brackets , y Fig. 3 is a top view of the'rear portion of the are secured to the handle by means of a. bolt 26. iron partially in section taken on the line 3_3 of _ In the top of the shell-or casing I6 there is formed ß Fig. 2. - Fig. 4 is a top view of the stamping forming the combined terminal post support and heel cover. and ' ' an opening 2l immediately forward of the heel I8 45 within which are positioned a pair of terminal posts $4. ‘ . ~ . _ At the rear .ofthé ironv underneath the shell or Fig. 5 is a cross sectionalview taken `on the linev « .casing the substantially 'Z shaped metal stamping _ 'l0 5_5 of Fig. 2 looking in the direction of the ar-, . )rows _ f Inthe construction of _electric sadirons many -factors must be taken into-v consideratlon when ` ' it is desired to build a ‘rugged structure which be-` 55- 'cause ofl weight of the iron alone is subjectto a î great deal of strain and abuse. It is furthermore essential to reduce the manufacturing cost of de 'vices of this_.sort to a figure as low as possible in order that the manufacturer may be able to meet I competition inthis highly developed art. Not above describedeis positioned and is designated by the character 3l. 'I‘he upper leg of the Z shaped stamping formed in the shape of a plate 32 lies adjacent the casing partially closing the opening plate Il and the forward 2l and the other leg forming a cover extends rearward adjacent the sole plate 55 heel Il. The plate I2 is provided at the end with a lug 36 vadapted to engage a depression 3l in theshell adjacent the opening 2l by means of which it is partially anchored to the casing. Formed also on the plate are a pair 2 2,133,600 in which are a pair of apertures 44. combined terminal post~ support and heel cover comprising a metal plate having upper and lower portions and a connecting plate therebetween. one of said portions being adapted to provide a The central bar 46 of the Z shaped section 3.0 is a plate like element somewhat trapezoidal in shape connecting the upper and lower plates 32 means for engaging a portion of the casing and locating means for -positioning the leg in the of projectionsl 48 designed to position the plate Within the opening 28. As viewed in Fig. 4 the plate 32 has a central'slightly dished portion 42 and 34. At the upper- end 48 the element is rounded slightly where it presses against the 10 bottom of the casing I6 adjacent the hole 28. -The lower plate 34 extends rearward substan tially horizontal-'to the soleplate and is provided with a flange 58 extending downward to add ri gidity to the plate and is provided also with an 16 upward extending rim 52 which ñts snugly within ‘edge of the heel I8. The upper plate 32 extends almost completely across the opening 28 forming a rigid bottom for the opening supported at both front and back 20 upon which the pair of terminal posts 54 previ ously referred to are mounted. 'I‘hese are insu lated from the plate by a series of mica. washers 58 and are held in place by a nut 58. Ample clearance is provided between the terminal posts 25 54 and the adjacent edges of the holes 44 in the «plate for insulating purposes. The terminal pests are connected by wires 60 to the heating element of the iron and a guard 62 protects the . posts from accidental blows which would tend to so knock them out of alignment. ' When the device is assembled the terminal posts are mounted and tightened into the holes 44- of the combined terminal support and heel cover which is then positioned upon the sole plate on a shelf at the rear indicated as numeral 62 and in this position the lower leg 34 extends rear wardas previously described. The lug 26 on the plate 32 is then positioned in the depression 38 provided for it adjacent the hole 28 in the casing and the shell or casing is then lowered into -place over the sole plate and there attached. Attach ment consists of pressing the Z shaped member 30 between the casing and the sole plate and supporting it at one end by üie lug 36. During 45 the operation the-»rim 52 of the Zshaped plate is engaged frictionally within the inside portion of the hollowfheel plate. The Z shaped part by the means described is securely clamped between stationary parts forming a base for the iron. Once the „parts are in place the insulated ter 50 minal posts 54, become ñrmly attached to the casing by means of the rigid positioning thereon of the part 30 and its upper plate 32. Due to the support provided by the lug 38 resting lupon -the shell and the somewhat columnar support of the cross bar 46 the dished portion 42 supporting the terminal posts is made extremely rigid when once secured in place. The central bar A46 by resting at one end on the sole plate and at the 60 other end against the shell, forms a spreader and reinforcement for the shell at a point of contact which is adjacent the terminal post opening 28 serving thus an added purpose. Some changes may be made in the construction 65 and arrangement of the parts of my device with cut departing from the real spirit and purpose of my invention and it is Amy intention to cover by my claims any modiñed forms of structure or use of mechanical equivalents which may be reason ably included within their scope.
