TERMINAL POST SUPPORT AND HEEL COVER Filed March 12, 1938 Womgya Patented Oct. v 1938 .l UNITED STATES A PATENT ori-ICE TERMINAL POST SUPPORT AND HEEL COVER tion of Missouri Appuminn umn iz, 193s. serai No. 195,534 s claims. (ci. 21a-25) My invention relates to sadirons and particularly to electric irons wherein a detachable guard supplied with a plug is ordinarily used for attachment to terminal posts on the iron. -Among the objects of my invention is the provision of a new and improved sadiron structure comprising the formation and adaptation of a metallic member adapted to serve as a support for the terminal posts and simultaneously provide a cover or closure for a portion of the iron casing commonly known as the heel.

Another object is the provision in an electric sadiron structure of a mounting for the terminal posts supplied by a single separate metallic part 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 electric sadiron of a .combined support for the terminal posts and cover for the under side of the heel which is made from a single stamping providedwith means'for engaging portions of the casing and adapted to be clamped into position against 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 point where the terminal posts are attached.

With these and other objects in view my invention consists in the construction, arrangement and combination of the various parts of my device whereby the objects contemplated are attained as hereinafter more fully set forth and pointed out in my claims and illustrated in the accompanying drawing in which:

extent the rigid requirements above recited, there has been provided a structural unit integral in itself, serving a plurality of purposes and requiring 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 l may be attached and extending rearward at the bottom leg to close a cavity formed at the rear of the iron by the application of a shell or casing extending rearward to form what is known as a heel or heel rest. As shown in the drawings an electric iron having 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 surmountlng the sole plate is a weight member Il attached thereto. Above the sole plate and weight is a shell or casing I6 which entirely covers the base portion of the iron and extendsy rearward at Il in the form of a hollow heel or heel rest. The 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 by means of a bracket 22 at the front and another bracket 24 at the rear 'and these brackets are secured to the handle by means of a. bolt 26.

In the top of the shell-or casing I6 there is formed an opening 2l immediately forward of the heel I8 within which are positioned a pair of terminal posts $4.

At the rear .ofth ironv underneath the shell or .casing the substantially 'Z shaped metal stamping above describedeis positioned and is designated by the character 3l. 'Ihe upper leg of the Z shaped stamping formed in the shape of a plate 32 lies adjacent the casing partially closing the opening 2l and the other leg forming a cover plate Il extends rearward adjacent the sole plate and the heel Il. The plate I2 is provided at the forward 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 plate for insulating purposes.

-The lower plate 34 extends rearward substantially horizontal-'to the soleplate and is provided with a flange 58 extending downward to add rigidity to the plate and is provided also with an upward extending rim 52 which ts 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 upon which the pair of terminal posts 54 previously referred to are mounted. 'Ihese are insulated 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 54 and the adjacent edges of the holes 44 in the 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 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 rearwardas 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. Attachment consists of pressing the Z shaped member 30 between the casing and the sole plate and supporting it at one end by ie lug 36. During 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 terminal posts 54, become rmly 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 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 and arrangement of the parts of my device withcut departing from the real spirit and purpose of my invention and it is Amy intention to cover by my claims any modied forms of structure or use of mechanical equivalents which may be reasonably included within their scope.
